Detailed Description
Hereinafter, embodiments of a connector and a connector-equipped electric wire according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiment.
[ embodiment ]
One embodiment of the connector and the connector-equipped electric wire according to the present invention will be described with reference to fig. 1 to 35.
Reference numeral 1 in fig. 1 to 4 denotes a connector according to the present embodiment. Note that reference symbol WH in fig. 1 to 4 denotes a connector-equipped electric wire attached in a state where the connector 1 is electrically connected to the electric wire We.
The connector 1 constitutes a connector device together with a mating side connector 101 (fig. 1). The connector device is a device that electrically connects objects to be connected electrically connected to the 1 st connector and the 2 nd connector to each other by physical and electrical connection between the 1 st connector and the 2 nd connector. Here, for convenience of explanation, the connector 1 is referred to as a 1 st connector, and the mating connector 101 is referred to as a 2 nd connector.
Here, the connection object refers to, for example, a power supply circuit such as an inverter, an electric device such as a rotating electric machine, and the like. For example, the connector 1 is electrically connected to an electric device (not shown) via an electric wire We. On the other hand, the mating connector 101 is attached to a case 201 (fig. 1) of the power circuit 200, and is electrically connected to the power circuit 200 via an electric wire (not shown). The connector 1 and the mating connector 101 are electrically connected to each other, thereby enabling electrical connection between the electrical apparatus and the power supply circuit 200, and enabling power supply from a power supply (a secondary battery or the like) to the electrical apparatus or charging of electricity generated by the electrical apparatus to the power supply.
The connector 1 of the present embodiment is inserted and fitted into the mating connector 101, and is electrically connected to the mating connector 101. On the other hand, the connector 1 is pulled out from the mating connector 101 and the electrical connection with the mating connector 101 is released. Here, the insertion and fitting direction is referred to as a "connector insertion direction", and the removal direction is referred to as a "connector removal direction". When the directions of these two directions are not specified, they are referred to as "connector insertion/removal directions". Regarding each of these directions, when the connector 1 is described as a main body, the direction of the connector 1 with respect to the mating connector 101 is shown, and when the mating connector 101 is described as a main body, the direction of the mating connector 101 with respect to the connector 1 is shown.
The connector 1 of the present embodiment may be a female connector having female terminals or a male connector having male terminals, as long as it has the configuration described in detail below. The connector 1 of the present embodiment may be configured as a shielded connector that suppresses noise from entering from the outside. In the following examples, the connector 1 will be described as a male connector, and the mating connector 101 will be described as a female connector. The connector 1 is described as being configured as a shielded connector.
The connector 1 of the present embodiment includes a terminal fitting 10 and a housing 20 (fig. 4 and 5).
The terminal fitting 10 of the present embodiment is formed of a conductive material such as metal (copper, copper alloy, aluminum alloy, or the like) into a male shape. In this example, a male terminal fitting 10 is formed by pressing a conductive metal plate as a base material, such as by cutting or bending. The terminal fitting 10 includes: an electrical connection portion 11 electrically connected to a mating side terminal 110 of the mating connector 101, which will be described later; and a wire connecting portion 12 electrically connected to a tip end of the wire We (fig. 4 and 6 to 9).
The electrical connection portion 11 of this example is formed in a male type. The electrical connection portion 11 is formed in a flat plate shape having 2 flat wall surfaces (the 1 st wall surface 11a, the 2 nd wall surface 11b) (fig. 9). Here, the electrical connection portion 11 is formed in a rectangular flat plate shape, and the 1 st wall surface 11a and the 2 nd wall surface 11b are disposed to face each other in a parallel state. The electrical connection portion 11 has at least one of the 1 st wall surface 11a and the 2 nd wall surface 11b as a contact portion that is physically and electrically connected to the mating terminal 110. Here, as described later, the counterpart terminal 110 has 2 electrical connection portions (the 1 st electrical connection portion 121, the 2 nd electrical connection portion 122), and therefore, the 1 st wall surface 11a and the 2 nd wall surface 11b are respectively made as contact portions to be electrically connected to the respective electrical connection portions.
The electric wire connection portion 12 of this example is physically and electrically connected to the tip end of the electric wire We. The wire connection portion 12 may be crimped to the end of the wire We by a process such as swaging, or may be fixed by welding. The electric wire connection portion 12 of this example is crimped to the end of the electric wire We.
In the terminal fitting 10 of this example, the one end portion 11c side of the electrical connection portion 11 disposed to face each other is a tip, and the wire connection portion 12 is disposed on the other end portion 11d side (fig. 6 to 9).
The terminal fitting 10 of this example has a virtual axis P (fig. 8 and 9) along the axial direction of the tip of the electric wire We that is physically and electrically connected to the electric wire connecting portion 12, and a held portion 13, an electrical connecting portion 11, and the electric wire connecting portion 12, which will be described later, are arranged in this order from the tip along the virtual axis P.
Specifically, the electrical connection portion 11 extends in a direction along the imaginary axis P (hereinafter simply referred to as "axial direction"). In the electrical connection portion 11, one end in the axial direction is the above-mentioned one end portion 11c, and the other end in the axial direction is the above-mentioned other end portion 11d (fig. 8 and 9). The electrical connection portion 11 has 2 end surfaces (a 1 st end surface 11e and a 2 nd end surface 11f) which are arranged to face each other and are different from the 2 end portions 11c and 11d which are arranged to face each other (fig. 8). The 1 st end face 11e and the 2 nd end face 11f are disposed in parallel to each other in a direction orthogonal to the axial direction of the terminal fitting 10 and the direction orthogonal to the 1 st and 2 nd wall surfaces 11a and 11b, respectively. In the electrical connection portion 11, the 1 st end surface 11e side and the 2 nd end surface 11f side around the virtual axis P are configured as substantially rectangular flat plates having the same shape.
The connector 1 of the present embodiment has the terminal fitting 10, for example, in each of a plurality of poles. Here, 2 terminal fittings 10 are provided (fig. 5). In the connector 1, although the case 20 has been described as having a plurality of similar terminal fittings 10, the terminal fittings 10 of this example and terminal fittings of different shapes from the terminal fittings 10 of this example may be mixed.
Next, the case 20 of the present embodiment will be described.
The housing 20 of the present embodiment includes a housing body 20A (fig. 2 to 5 and 10) that houses the terminal fitting 10. Further, the case 20 of the present embodiment has a shield cover 20B that covers a portion from the accommodating body 20A to the tip of the electric wire We while taking the portion inside (fig. 1 to 5). Further, the housing 20 of the present embodiment includes a holding member 20C (fig. 4 and 5) for preventing the terminal fitting 10 from coming off the housing body 20A on the electric wire We side.
First, the accommodating body 20A will be explained.
The container 20A is molded from an insulating material such as synthetic resin. The housing body 20A houses the electrical connection portion 11 in a housing space 33 described later on the inside, and projects the wire connection portion 12 to the outside. The accommodating body 20A of the present embodiment is roughly divided into a 1 st accommodating member 30 and a 2 nd accommodating member 40 (fig. 2 to 5 and 10).
The 1 st accommodating member 30 is shaped as a cylindrical body having at least one end opened in the cylinder axis direction. Therefore, the 1 st accommodating member 30 has a cylindrical outer peripheral wall 31 (fig. 3 to 5 and 10). The 1 st accommodating member 30 of this example forms the outer peripheral wall 31 in a square cylindrical shape, and has one end in the cylinder axis direction open and the other end closed. In the 1 st receiving member 30, the mating terminal 110 is inserted into the receiving space 33 (fig. 2 and 10) from the opening 32 (fig. 2, 4, and 10) at the one end along the cylinder axis direction. Strictly speaking, however, the mating terminals 110 are inserted into the accommodating space 33 from the opening 32 via the 2 nd accommodating member 40 as described later.
In the outer peripheral wall 31, an end portion on the opening 32 side thereof serves as a fitting portion (connector fitting portion) 31a (fig. 4 and 10) to be fitted with a later-described connector fitting portion 153e of the mating connector 101. The connector fitting portion 153e is inserted and fitted inside the connector fitting portion 31 a. An annular sealing member Se1 (fig. 4, 5, and 10) is concentrically attached to the outer peripheral surface of the connector fitting portion 31 a.
The outer peripheral wall 31 has an insertion hole 34 (fig. 5 and 10) for inserting the terminal fitting 10 into the accommodation space 33 from the front end on the electrical connection portion 11 side. The 1 st accommodating member 30 of this example accommodates the electrical connection portion 11 in the accommodating space 33 inside, and on the other hand, protrudes the electric wire connection portion 12 from the insertion hole 34 to the outside (fig. 4).
Here, the insertion hole 34 is provided for each terminal fitting 10. Therefore, 2 insertion holes 34 are formed in the outer peripheral wall 31 of this example (fig. 5 and 10). Each insertion hole 34 is formed and arranged so that each terminal fitting 10 is inserted with the axial direction of each other in the same orientation. That is, here, the axial direction of the terminal fitting 10 is an insertion direction of the terminal fitting 10 into the housing space 33 (hereinafter, referred to as "terminal insertion direction"). Further, each insertion hole 34 is formed and configured such that each terminal fitting 10 is inserted in a state where the 1 st and 2 nd end surfaces 11e, 11f of the electrical connection portion 11 are directed toward the cylinder axis direction of the outer peripheral wall 31 (that is, a state where the 1 st and 2 nd wall surfaces 11a, 11b of the electrical connection portion 11 are made to follow the cylinder axis direction of the outer peripheral wall 31).
The 1 st housing member 30 of this example has a guide portion 35 (fig. 4 and 10) that guides the terminal fitting 10 to be inserted into the housing space 33 through the insertion hole 34. For example, the insertion hole 34 is continued to the wall body 36 at the other end of the outer peripheral wall 31 in the cylinder axis direction. Therefore, the guide portion 35 is provided on the wall surface 36a of the wall body 36 on the side of the housing space 33. The guide portion 35 is provided to the terminal fitting 10. Therefore, in the wall surface 36a of this example, the guide portion 35 is provided at 2.
The guide portion 35 of this example has 2 protruding portions 35a (fig. 10) that protrude from this wall surface 36a toward the cylinder axis direction of the outer peripheral wall 31 and extend in the terminal insertion direction. The projections 35a are arranged to face each other with a space therebetween. The space does not prevent the electric connection part 11 from being inserted into the accommodating space 33Is set to a size equal to the plate thickness of the electrical connection portion 11. Therefore, in the guide portion 35, a groove (hereinafter, referred to as "guide groove") 35b (fig. 4 and 10) is formed between the respective projections 35a along the terminal insertion direction. In the terminal fitting 10, the electrical connection portion 11 is guided along the guide groove 35b from the one end portion 11c side. In addition, the guide groove 35b is set to a size equal to the plate thickness of the electrical connection portion 11 as described above, so that the play of the electrical connection portion 11 between the respective protruding portions 35a can be suppressed. In this example, the groove bottom 35b of the guide groove 35b is1Is raised toward the opening 32 side than the wall surface 36a (fig. 4).
Further, the guide portion 35 of this example has a guide wall surface 35c that guides the one end portion 11c side of the electrical connection portion 11 inserted from the insertion hole 34 to the guide groove 35b (fig. 4 and 10). The guide wall surface 35c guides the one end 11c side of the electrical connection portion 11 from the wall surface 36a to the groove bottom 35b of the guide groove 35b1Is provided.
The 2 nd accommodating member 40 is shaped as a polyhedron matching the shape of the accommodating space 33 of the 1 st accommodating member 30 (fig. 10 and 11). The 2 nd accommodating member 40 is accommodated in the accommodating space 33 from the opening 32 of the 1 st accommodating member 30 in the cylinder axis direction (fig. 2, 4, 5, and 10). The 2 nd accommodating member 40 accommodates the electrical connection portion 11 of the terminal fitting 10 inside itself in a state where the accommodation into the accommodation space 33 is completed (fig. 4).
The 2 nd accommodating member 40 has a terminal accommodating chamber 41 (fig. 4, 5, and 10 to 12) that accommodates the electrical connection portion 11 in the accommodating space 33. This terminal accommodating chamber 41 starts to accommodate the electrical connection portion 11 accommodated in the accommodating space 33 from the opening 41a (fig. 5, 10, and 11) as the 2 nd accommodating member 40 is inserted into the accommodating space 33. Then, the terminal accommodating chamber 41 once completes the accommodation of the 2 nd accommodating member 40 into the accommodating space 33, the accommodation of the electrical connection portion 11 is completed. Therefore, the 2 nd accommodating member 40 has a notch portion 42 (fig. 5, 10, and 11) on the outer peripheral surface side, which communicates the terminal accommodating chamber 41 with the outside of the 2 nd accommodating member 40. The electric wire connection portion 12 protrudes from the notch portion 42 to the outside of the 2 nd accommodating member 40. The notch portion 42 is disposed to face the insertion hole 34 in a state where the 2 nd accommodating member 40 is accommodated in the accommodating space 33 such that the electric wire connecting portion 12 protrudes outside from the insertion hole 34 of the 1 st accommodating member 30.
When fitting of the connector 1 with the mating connector 101 (hereinafter, referred to as "connector fitting") is completed, the later-described 1 st and 2 nd electrical connection portions 121, 122 and 2 contact members 130 of the mating terminal 110 are accommodated in the terminal accommodating chamber 41. In the terminal accommodating chamber 41, the respective contact members 130 are brought into contact with the 1 st wall surface 11a and the 2 nd wall surface 11b of the electrical connection portion 11, respectively, to be physically and electrically connected to each other. Therefore, the 2 nd accommodating member 40 has a terminal insertion port 43 for inserting the counterpart side terminal 110 into the terminal accommodating chamber 41 (fig. 2, 3, 10, and 12). The terminal insertion port 43 is formed to be arranged on the opening 32 side of the 1 st accommodating member 30 in a state where the 2 nd accommodating member 40 is accommodated in the accommodating space 33, and is arranged to face the terminal accommodating chamber 41 in the cylinder axis direction of the outer peripheral wall 31. Therefore, either the 1 st end surface 11e or the 2 nd end surface 11f of the electrical connection portion 11 accommodated in the accommodation space 33 is disposed opposite to the terminal insertion port 43.
The 2 nd accommodating member 40 has a communication chamber 44 (fig. 2, 3, 10, and 12) for allowing the terminal accommodating chamber 41 and the terminal insertion port 43 to communicate with each other in the cylinder axial direction of the outer peripheral wall 31. Therefore, when the electrical connector 11 is accommodated in the terminal accommodation chamber 41, one of the 1 st end surface 11e and the 2 nd end surface 11f is disposed to face the terminal insertion port 43 with the communication chamber 44 interposed therebetween.
The 2 nd accommodating member 40 has a contact preventing portion 45, and the contact preventing portion 45 prevents a finger of an operator or the like from touching the electrical connection portion 11 through the terminal insertion port 43 (fig. 2 to 4, 10, and 12). The contact preventing portion 45 is formed and arranged so that a finger does not reach the electrical connection portion 11 via the terminal insertion port 43. For example, the contact preventing portion 45 is disposed so as to cover at least a part of an end surface (the 1 st end surface 11e or the 2 nd end surface 11f) of the electrical connection portion 11 disposed opposite to the terminal insertion port 43 from the terminal insertion port 43 side in the cylinder axis direction of the outer peripheral wall 31. The contact preventing portion 45 is provided in the communicating chamber 44 so as not to hinder the insertion of the mating terminal 110 into the terminal accommodating chamber 41.
The contact preventing portion 45 of this example is formed in a flat plate shape having 2 flat wall surfaces, and the 2 wall surfaces are formed in the communication chamber 44 so as to be along the cylinder axial direction of the outer peripheral wall 31. Here, the contact preventing portion 45 is formed in a rectangular flat plate shape. Then, the contact preventing portion 45 is configured to divide the communication chamber 44 into 2 compartments in a direction orthogonal to the 1 st and 2 nd wall surfaces 11a, 11b of the electrical connection portion 11. That is, the communication chamber 44 is divided into a 1 st divided communication chamber 44a and a 2 nd divided communication chamber 44b in the orthogonal direction by the contact preventing portion 45 (fig. 2, 3, 10, and 12). Further, here, the terminal insertion opening 43 is also divided into a 1 st divided insertion opening 43a and a 2 nd divided insertion opening 43b in the orthogonal direction by the contact preventing portion 45 (fig. 2, 3, 10, and 12). Therefore, the 1 st electrical connection portion 121 of the mating terminal 110, which will be described later, is inserted into the terminal accommodating chamber 41 through the 1 st split insertion port 43a and the 1 st split communication chamber 44 a. Further, a 2 nd electrical connection portion 122, which will be described later, of the mating terminal 110 is inserted into the terminal accommodating chamber 41 through the 2 nd split insertion port 43b and the 2 nd split communication chamber 44 b.
In this example, after a combination of a pair of the 1 st electrical connection portion 121 and one contact member 130, which will be described later, and the 1 st housing body 151 are inserted into the 1 st divided communication chamber 44a from the 1 st divided insertion port 43a, they are inserted into the terminal housing chamber 41. In the terminal accommodating chamber 41, the one contact member 130 is brought into contact with the 1 st wall surface 11a of the electrical connection portion 11, thereby electrically connecting the electrical connection portion 11 with the 1 st electrical connection portion 121. In this example, the 2 nd accommodating body 152 and a combination of the pair of 2 nd electrical connection portions 122 and the other contact member 130, which will be described later, are inserted into the 2 nd divided communication chamber 44b from the 2 nd divided insertion port 43b, and then are inserted into the terminal accommodating chamber 41. In the terminal accommodating chamber 41, the other contact member 130 is brought into contact with the 2 nd wall surface 11b of the electrical connection portion 11, thereby electrically connecting the electrical connection portion 11 with the 2 nd electrical connection portion 122. Therefore, the 1 st divided insertion port 43a, the 2 nd divided insertion port 43b, the 1 st divided communication chamber 44a, the 2 nd divided communication chamber 44b, and the contact preventing portion 45 are formed and provided in the 2 nd accommodating member 40 so as to be able to be inserted thereinto.
The 2 nd accommodating member 40 has a terminal holding portion 46 that holds the held portion 13 (fig. 3, 4, and 6 to 9) of the terminal fitting 10 so that the electrical connection portion 11 does not come off from the terminal accommodating chamber 41 (fig. 4 and 11). The terminal holding portion 46 is formed so as not to detach the electrical connection portion 11 from the terminal accommodating chamber 41 by holding the held portion 13 (fig. 4). The held portion 13 and the terminal holding portion 46 are formed and arranged so as to be able to hold at least one of the leading end side and the base end side of the terminal fitting 10. In the terminal fitting 10 of this example, the wire connecting portion 12 is made to protrude to the outside of the accommodating body 20A. Therefore, the base end side of the terminal fitting 10, which is the location of the held portion 13, is the end 11d of the electrical connection portion 11 on the wire connection portion 12 side. For example, the held portion 13 is formed as an inserted portion at the tip of the terminal fitting 10, and the terminal holding portion 46 is formed as an insertion portion that is inserted into the held portion 13 at the same time as the 2 nd accommodating member 40 is inserted into the accommodating space 33. Then, the held portion 13 and the terminal holding portion 46 are formed to lock the movement of the terminal fitting 10 in the terminal insertion direction with respect to the housing space 33 and the movement of the terminal fitting 10 in the direction opposite to the terminal insertion direction.
Specifically, the held portion 13 of this example is formed in a T-shape protruding from the front end (one end portion 11c) of the electrical connection portion 11 along the imaginary axis P. The held portion 13 includes: a T-shaped 1 st wall surface 13a arranged on the same plane as the 1 st wall surface 11a of the electrical connection portion 11 (fig. 6, 8, and 9); and a T-shaped 2 nd wall surface 13b disposed on the same plane as the 2 nd wall surface 11b of the electrical connection portion 11 (fig. 7 and 9). Further, the held portion 13 includes: a T-shaped shaft portion 13c having a central axis disposed on the imaginary axis P; and an intersecting portion 13d that is orthogonal to the shaft portion 13c at the tip of the shaft portion 13c (fig. 6 to 9). The held portion 13 uses a slit-shaped groove portion 13e (fig. 4 and 6 to 9)) formed between the electric connecting portion 11 and the one end portion 11c as an inserted portion. The groove 13e is formed at 2 centered on the imaginary axis P.
The held portion 13 in this example is formed in a direction orthogonal to the axial direction and the orthogonal direction to the 1 st and 2 nd wall surfaces 13a and 13b, and both shapes around the virtual axis P are the same. Therefore, the held portion 13 can use both the groove portions 13e as the inserted portions. For example, in the case where the 1 st end surface 11e of the terminal fitting 10 is disposed in the terminal accommodating chamber 41 so as to face the terminal insertion port 43, one of the 2 groove portions 13e is used as an inserted portion. In addition, in the terminal fitting 10, in a case where the 2 nd end surface 11f is disposed in the terminal accommodating chamber 41 so as to face the terminal insertion port 43, the other of the 2 groove portions 13e is used as an inserted portion.
The terminal holding portion 46 is inserted into the groove portion 13e of the held portion 13 in a state where the 2 nd accommodating member 40 is accommodated in the accommodating space 33. In this example, a slit-shaped groove portion 41b1 (fig. 11) cut along the cylindrical axial direction of the outer peripheral wall 31 is formed in the wall portion 41b constituting the terminal accommodating chamber 41. The terminal holding portion 46 of this example uses the remaining portion of the wall portion 41b having the bottom side of the groove portion 41b1 as an insertion portion into the held portion 13. In the held portion 13 and the terminal holding portion 46 of this example, the fitting of the groove portions 13e, 41b1 with each other is also started as the 2 nd accommodating member 40 is inserted into the accommodating space 33. Then, in the held portion 13 and the terminal holding portion 46, the insertion of the remaining portion of the wall portion 41b into the groove portion 13e is completed at the same time as the accommodation of the 2 nd accommodating member 40 into the accommodating space 33 is completed, and the electrical connection portion 11 can be held in the accommodated state in the terminal accommodating chamber 41.
Here, in the held portion 13, when the remaining portion of the wall portion 41b is inserted into the groove portion 13e, the intersection portion 13d is disposed outside the outer peripheral surface of the 2 nd accommodating member 40 (fig. 3 and 4). Therefore, in the housing 20A, an annular gap 21 (fig. 3 and 4) is provided between the inner peripheral surface of the 1 st housing member 30 and the outer peripheral surface of the 2 nd housing member 40. The gap 21 is set to a size at which the intersection 13d can be disposed and at which fingers of an operator or the like cannot enter. In the connector 1, the conduction test can be performed by the intersection 13d provided in the gap 21.
However, in the guide portion 35 illustrated previously, looseness of the electrical connection portion 11 between the respective protruding portions 35a can be suppressed. In the electrical connection portion 11, the 2 nd volumeIn a state where the receiving part 40 is accommodated in the accommodating space 33, one of the 1 st end surface 11e and the 2 nd end surface 11f is arranged to be in contact with the groove bottom 35b of the guide groove 35b1The other of the contact preventing portions is arranged to face an end face 45a (an end face on the opposite side to the terminal insertion port 43 side) of the contact preventing portion 45 (fig. 4). Therefore, the 1 st receiving part 30 and the 2 nd receiving part 40 may be formed to utilize the groove bottom 35b in a state of receiving them completely with each other1And the end face 45a sandwich the electrical connection portion 11. That is, the 1 st accommodating member 30 and the 2 nd accommodating member 40 may be formed to hold the electrical connection portion 11 by sandwiching in a state where the accommodation therebetween is completed. In this way, the connector 1 can improve the effect of preventing the electrical connection portion 11 from coming off the terminal accommodating chamber 41 by the terminal holding portion 46, and can suppress the looseness of the electrical connection portion 11 in the terminal accommodating chamber 41. Therefore, the connector 1 can improve vibration resistance and improve the fitting operability with the mating connector 101. In the connector 1 of this example, in order to obtain such an effect, as described later, the 1 st receiving member 30 and the 2 nd receiving member 40 are fastened to the shield shell 20B by an axial force in the cylindrical direction.
In this 2 nd accommodating member 40, a combination of the terminal accommodating chamber 41, the notched portion 42, the terminal insertion port 43, the communication chamber 44, the contact preventing portion 45, and the terminal holding portion 46 is provided for each terminal fitting 10. Each combination is configured to accommodate the plurality of terminal fittings 10 in such a manner that the axial direction of each other and the terminal insertion direction with respect to the accommodating space 33 are the same direction. In this example, 2 such combinations are provided. One of them is formed and arranged in combination to accommodate the electric connection portion 11 of the terminal fitting 10 in the terminal accommodating chamber 41 in a state where the 1 st end surface 11e is arranged to face the terminal insertion port 43 (that is, in a state where the 1 st and 2 nd wall surfaces 11a, 11b are arranged along the cylinder axis direction of the outer peripheral wall 31). The electrical connection portion 11 is inserted into the terminal accommodating chamber 41 from the 1 st end face 11e side. The other is formed and arranged in combination so that the electrical connection portion 11 of the terminal fitting 10 is accommodated in the terminal accommodating chamber 41 in a state where the 2 nd end surface 11f is arranged to face the terminal insertion port 43 (that is, in a state where the 1 st and 2 nd wall surfaces 11a and 11b are arranged along the cylindrical axial direction of the outer peripheral wall 31). The electrical connection portion 11 is inserted into the terminal accommodating chamber 41 from the 2 nd end surface 11f side.
Next, the shield case 20B will be explained.
The shield case 20B is a 1 st shield member that suppresses intrusion of noise from the outside between the accommodating body 20A assembled with the 1 st accommodating member 30 and the 2 nd accommodating member 40 and the tip end of the electric wire We. The shield case 20B covers the portion from the outside while taking the portion inside. The shield case 20B is formed of a conductive material such as metal. The shield case 20B includes: a main shield 51 that exposes the opening 32 side and covers the accommodating body 20A from the outside; and a sub-shield 52 covering the wire connecting portion 12 and the end of the wire We protruding from the insertion hole 34 to the outside of the accommodating body 20A from the outside (fig. 1 to 5, 13, and 14).
The main shield 51 has a cylindrical outer peripheral wall 51a (fig. 1 to 5, 13, and 14) having one end open and the other end closed. The outer peripheral wall 51a of this example is formed in a square tube shape matching the outer shape of the 1 st accommodating member 30 in a square tube shape. In the main shield 51, the 1 st receiving member 30 is inserted into the receiving space 51c (fig. 14) from the opening 51b (fig. 2, 4, and 14) at one end thereof along the axial direction of the two members. The seal member Se1 is closely attached to the inner peripheral surface of the outer peripheral wall 51a in a state where the 1 st housing member 30 is housed in the housing space 51c, and improves the liquid-tightness between the connector fitting portion 31a and the main shield 51 (fig. 4).
The outer peripheral wall 51a has a through hole 51a disposed to face the insertion hole 34 in a state where the 1 st accommodating member 30 is accommodated in the accommodating space 51c1(FIG. 14). The through hole 51a1Provided for each terminal fitting 10. In this example, 2 through holes 51a are provided1。
The sub-shield 52 is provided for each terminal fitting 10. Therefore, here, 2 of the sub-shielding bodies 52 are provided. The sub-shield 52 is formed in a cylindrical shape with both ends open. The sub-shield 52 of this example is formed in a cylindrical shape. In the shield case 20B, the sub-shield 52 is inserted from the through hole 51a of the main shield 511The edge portion of (b) protrudes toward the outside of the main shield 51. The sub-shield 52 of this example protrudes in a manner such that the cylinder axis direction is along the terminal insertion directionAnd (6) discharging. In the sub-shield 52, the terminal fitting 10 is inserted into the receiving space 52b (fig. 5) from the opening 52a on the free end side. The terminal fitting 10 passes through the through hole 51a of the main shield 511And the insertion hole 34 of the 1 st receiving member 30 into the receiving space 33 from the front end.
The shield case 20B has a coupling body 53 (fig. 2 to 5 and 13) for coupling the adjacent 2 sub-shield bodies 52 arranged side by side. The connecting member 53 may be any connecting member as long as it connects 2 adjacent sub-shields 52 arranged side by side, and may be a connecting member connecting all sub-shields 52 (for example, 3 sub-shields 52). The connecting body 53 of this example exists between 2 adjacent sub-shield bodies 52 arranged side by side. The connecting body 53 is screwed to a wall surface 201a (fig. 1) of a conductive installation object (in this example, a housing 201 made of a conductive material such as metal) of the mating connector 101 in a connector fitting state, thereby fixing the connector 1 to the mating connector 101. Therefore, the connecting body 53 has a through hole 54 (fig. 3) used for fastening the screw. The through hole 54 will be described in detail later.
Here, a ring-shaped seal member Se2 (fig. 4 and 5) is concentrically attached to the end of the electric wire We. The sealing member Se2 is closely attached to the inner peripheral surface of the sub-shield 52 in a state where the electrical connection portion 11 is accommodated in the accommodation space 33, and improves the liquid-tightness between the sub-shield 52 and the electric wire We (fig. 4).
The holding member 20C has a cylindrical outer peripheral wall (outer peripheral wall 62 described later) into which an end portion of the sub-shield 52 on the opening 52a side is fitted, and the holding member 20C is a cylindrical member formed so as to be able to pull out the electric wire We wired in the housing space 52b of the sub-shield 52 to the outside. The holding member 20C is formed of a conductive material such as metal. The holding member 20C is provided for each terminal fitting 10. In this example, there are 2 holding members 20C.
The holding member 20C of this example has a cylindrical inner peripheral wall 61 and a cylindrical outer peripheral wall 62 (fig. 13 and 14) concentrically arranged at a radial interval. The inner peripheral wall 61 and the outer peripheral wall 62 are open at both ends in the cylinder axis direction, respectively. Therefore, in the holding member 20C, a cylindrical gap 63 is formed between the inner peripheral wall 61 and the outer peripheral wall 62 (fig. 14). In the holding member 20C of this example, an annular opening at one end in the cylindrical axial direction of the cylindrical gap 63 is closed by an annular wall (hereinafter referred to as "annular wall") 64 (fig. 13). The holding member 20C is configured such that the end portion of the sub-shield 52 on the opening 52a side is inserted into and fitted into the cylindrical gap 63 from the opening 63a (fig. 14) on the other end in the cylindrical axis direction. Therefore, in this holding member 20C, the inner peripheral wall 61 is inserted into the accommodation space 52b of the sub-shield 52, and the outer peripheral wall 62 covers the outer peripheral surface of the outer peripheral wall 52C of the sub-shield 52 (fig. 13 to 15). In this holding member 20C, the electric wire We wired in the accommodation space 52b of the sub-shield 52 is guided to the space inside the inner peripheral wall 61, and is pulled out to the outside from the opening at one end of the inner peripheral wall 61.
The sub-shield 52 and the holding member 20C are held in a fitted state by the lock mechanism L (fig. 13 and 14). In this example, a locking mechanism L is provided at 2. The lock mechanism L includes: a 1 st engaging body 55 provided on the sub-shield body 52; and a 2 nd engaging body 65 provided on the holding member 20C.
The 1 st engaging body 55 projects radially outward from the outer peripheral wall 52c at the end of the sub-shield body 52 on the opening 52a side. The 1 st engaging body 55 of this example is formed in a claw shape capable of hooking the 2 nd engaging body 65.
On the other hand, the 2 nd engaging body 65 is provided in a portion other than a part in the circumferential direction in the outer circumferential wall 62 of the holding member 20C. The 2 nd engaging body 65 of this example has a base portion 65a (fig. 13 and 14) that protrudes radially outward from the outer peripheral surface of the inner peripheral wall 61 on the same plane as the annular wall 64. Further, the 2 nd engaging body 65 of this example has flexible 1 st and 2 nd flexible shaft portions 65b, 65c at both ends of the base portion 65a in the circumferential direction, respectively (fig. 13 and 14). The 1 st and 2 nd flexible shaft portions 65b and 65C project from both ends of the base portion 65a in the circumferential direction in the cylindrical axial direction of the holding member 20C toward the opening 63 a. The 1 st and 2 nd flexible shaft portions 65b and 65C are disposed at positions equal to the outer peripheral wall 62 in the radial direction of the holding member 20C. Further, the 2 nd engaging body 65 of this example has an engaging portion 65d (fig. 13 and 14) that connects the projecting end portions of the 1 st and 2 nd flexible shaft portions 65b and 65c, respectively. The 2 nd engaging body 65 can move the engaging portion 65d in the radial direction with respect to the inner peripheral wall 61 by bending the 1 st and 2 nd flexible shaft portions 65b and 65 c.
In this lock mechanism L, the holding member 20C is initially inserted and fitted into the end portion of the sub-shielding body 52 on the opening 52a side, and the 2 nd engaging body 65 is bent while the engaging portion 65d is caused to jump over the 1 st engaging body 55. In the lock mechanism L, when the fitting of the sub-shield 52 to the holding member 20C is completed, the engaging portion 65d of the 2 nd engaging body 65 passes over the 1 st engaging body 55, and the 2 nd engaging body 65 is released from the bending. Accordingly, in the lock mechanism L, the engagement portions 65d of the 1 st engaging body 55 and the 2 nd engaging body 65 can be locked in the cylinder axis direction of the outer peripheral wall 62, and the holding member 20C is prevented from being disengaged from the sub-shielding body 52.
Here, the outer peripheral wall 52c of the sub-shield 52 at the end on the opening 52a side has a locking body. The locking body is preferably a protrusion protruding from the outer peripheral wall 52c at the end of the sub-shield 52 on the opening 52a side, and a plurality of locking bodies are provided on the outer peripheral wall 52 c. The holding member 20C has a gap in the outer peripheral wall 62 into which the locking body is inserted. In the lock mechanism L, the holding member 20C is fitted to the end portion of the sub-shield body 52 on the opening 52a side, and the 1 st engaging body 55 and the 2 nd engaging body 65 are completely engaged with each other, and the engaging bodies are inserted into the gap. Here, 2 locking bodies (the 1 st and 2 nd locking bodies 56A, 56B) are provided in the sub-shield body 52, and 2 gaps (the 1 st and 2 nd gaps 66A, 66B) are provided in the holding member 20C (fig. 13 and 14). In this lock mechanism L, in a state where the holding member 20C is fitted to the end portion on the opening 52a side of the sub-shield body 52 and the 1 st engaging body 55 and the 2 nd engaging body 65 are engaged, the 1 st engaging body 56A is inserted into the 1 st gap 66A and the 2 nd engaging body 56B is inserted into the 2 nd gap 66B.
Specifically, the 1 st and 2 nd locking bodies 56A and 56B in this example protrude from the outer peripheral wall 52c toward the radially outer side at the end portions of the sub-shield 52 on the opening 52a side, and extend in the cylindrical axis direction of the sub-shield 52. Here, the 1 st and 2 nd locking bodies 56A and 56B are formed in a rectangular shape. Further, the 1 st and 2 nd engaging bodies 56A and 56B of this example are formed as the outer peripheral wall 52c at the end portion on the opening 52a side of the sub-shield body 52, and the 1 st engaging body 55 is interposed between these two engaging bodies in the circumferential direction of the sub-shield body 52. On the other hand, by providing the 1 st and 2 nd gaps 66A, 66B in the outer peripheral wall 62, there are formed: one end portion 62a constituting one wall surface of the 1 st gap 66A; and the other end 62B, which constitutes one wall surface of the 2 nd gap 66B (fig. 13 and 14). The 1 st gap 66A of this example is provided between the one end portion 62a and the 1 st flexible shaft portion 65b in the circumferential direction of the outer peripheral wall 62 (fig. 13 and 14). The 2 nd gap 66B of this example is provided between the other end portion 62B and the 2 nd flexible shaft portion 65c in the circumferential direction of the outer circumferential wall 62 (fig. 13 and 14).
The 1 st locking body 56A and the 1 st gap 66A are formed and arranged such that when the 1 st locking body 56A is inserted into the 1 st gap 66A, one end and the other end of the 1 st locking body 56A in the circumferential direction are respectively arranged opposite to the 1 st flexible shaft portion 65b in the circumferential direction with respect to the one end 62a of the outer circumferential wall 62 between the one end 62a of the outer circumferential wall 62 and the 1 st flexible shaft portion 65 b. Then, the 1 st locking body 56A and the 1 st gap 66A are formed and arranged so as to be able to suppress relative rotation between the sub-shield 52 and the holding member 20C in the circumferential direction. For example, the 1 st locking body 56A and the 1 st gap 66A are formed and arranged such that: the circumferential distance between one end of the 1 st locking body 56A in the circumferential direction and the one end 62a of the outer circumferential wall 62 and the circumferential distance between the other end of the 1 st locking body 56A in the circumferential direction and the 1 st flexible shaft portion 65b are each as narrow as possible within a range in which the 1 st locking body 56A can be inserted into the 1 st gap 66A. Accordingly, the 1 st locking body 56A is locked in the circumferential direction with respect to the one end portion 62a of the outer circumferential wall 62 or the 1 st flexible shaft portion 65b when the sub-shield body 52 and the holding member 20C are about to rotate relative to each other in the circumferential direction. Therefore, the 1 st locking body 56A and the 1 st gap 66A can suppress relative rotation of the sub-shield 52 and the holding member 20C in the circumferential direction.
Similarly, the 2 nd locking body 56B and the 2 nd gap 66B are formed and arranged such that when the 2 nd locking body 56B is inserted into the 2 nd gap 66B, one end and the other end of the 2 nd locking body 56B in the circumferential direction are respectively arranged so as to face the other end 62B of the outer circumferential wall 62 and the 2 nd flexible shaft portion 65c in the circumferential direction between the other end 62B of the outer circumferential wall 62 and the 2 nd flexible shaft portion 65 c. Then, the 2 nd locking body 56B and the 2 nd gap 66B are formed and arranged so as to be able to suppress relative rotation in the circumferential direction between the sub-shield 52 and the holding member 20C. For example, the 2 nd locking body 56B and the 2 nd gap 66B are formed and arranged such that: the circumferential distance between one end of the 2 nd locking body 56B in the circumferential direction and the other end 62B of the outer circumferential wall 62 and the circumferential distance between the other end of the 2 nd locking body 56B in the circumferential direction and the 2 nd flexible shaft portion 65c are each as narrow as possible within a range in which the 2 nd locking body 56B can be inserted into the 2 nd gap 66B. Accordingly, the 2 nd locking body 56B is locked in the circumferential direction with respect to the other end portion 62B of the outer circumferential wall 62 or the 2 nd flexible shaft portion 65C when the sub-shield body 52 and the holding member 20C are about to rotate relative to each other in the circumferential direction. Therefore, the 2 nd locking body 56B and the 2 nd gap 66B can suppress relative rotation of the sub-shield 52 and the holding member 20C in the circumferential direction.
The connector 1 includes a 2 nd shield member 71 (fig. 1 to 5 and 15) electrically connected to the shield shell 20B in addition to the shield shell 20B as the 1 st shield member. The 2 nd shield member 71 covers the end portion of the sub-shield 52 on the opening 52a side and the electric wire We pulled out from the opening 52a from the outside, thereby suppressing intrusion of noise from the outside into the electric wire We. The 2 nd shield member 71 is formed in a cylindrical shape and provided for each terminal fitting 10. Here, there are 2 nd shield members 71. In this connector 1, the electric wire We is pulled out to the outside from the holding member 20C that has been attached to the opening 52a of the sub-shield 52. Therefore, the 2 nd shield member 71 of this example is formed to cover the end portion on the opening 52a side of the sub-shield 52, the holding member 20C, and the electric wire We drawn out from the holding member 20C from the outside. Accordingly, the 2 nd shield member 71 can suppress intrusion of noise from the outside into the electric wire We drawn out from the holding member 20C. Specifically, the 2 nd shield member 71 of this example is provided as a braid obtained by braiding conductive strands into a cylindrical and mesh shape. Therefore, the 2 nd shield member 71 of this example has flexibility and can follow the movement such as bending of the inner electric wire We. In the drawings, specific shapes (meshes and the like) of the 2 nd shielding member 71 are omitted for convenience of illustration.
The 2 nd shield member 71 is fixed to the sub-shield 52 by a binding member (binding tape 75) made of a conductive material such as a metal (fig. 4, 5, and 15). The binding tape 75 is a binding tape known in the art. For example, the binding tape 75 is wound around the 2 nd shield member 71 and the end portion of the sub-shield 52 on the opening 52a side from above the 2 nd shield member 71. The binding tape 75 is formed into an annular shape by fastening, and the 2 nd shield member 71 is fixed to the end portion of the sub-shield 52 on the opening 52a side.
Here, the binding tape 75 is wound around the end surface 62C on the opening 63a side of the outer peripheral wall 62 of the holding member 20C and the end surface 56A on the main shield 51 side of the 1 st and 2 nd locking bodies 56A and 56B at positions opposed to each other in the cylindrical axis direction of the sub-shield 52 (fig. 15). Based on this, the binding tape 75 that forms a ring shape (here, an annular shape) after being wound is disposed opposite to the end surface 62c of the outer peripheral wall 62 and the end surfaces 56A of the 1 st and 2 nd locking bodies 56A and 56B in the cylinder axial direction. In this example, the end surfaces 56A of the 1 st and 2 nd locking bodies 56A and 56B are made to protrude in the cylinder axial direction with respect to the end surface 62c of the outer peripheral wall 62. Accordingly, the end surfaces 56A of the 1 st and 2 nd locking bodies 56A and 56B can function as locking portions that can lock the fastened bundling tapes 75 in the tube axis direction. For example, in the connector 1, when a tensile force in a direction of pulling out the second shield member 52 is generated to the 2 nd shield member 71, even if the binding tape 75 moves together with the 2 nd shield member 71 in the tube axis direction relative to the second shield member 52, the binding tape 75 can be locked by the end surfaces 56A of the 1 st and 2 nd locking bodies 56A and 56B. Therefore, in the connector 1, the state in which the 2 nd shield member 71 is fastened to the sub-shield 52 can be maintained. Therefore, the connector 1 can keep the physical connection and the electrical connection state between the sub-shield 52 and the 2 nd shield member 71, and therefore, the reduction of the shielding performance can be suppressed. As described above, in the connector 1, the 1 st and 2 nd locking bodies 56A and 56B have a function of holding the sub-shield 52 by the 2 nd shield member 71, and also have a function of suppressing the relative rotation of the holding member 20C with respect to the sub-shield 52 as described above. Therefore, the connector 1 can suppress an increase in the size of the main body as compared with a case where each function is realized by a different site.
Further, in this connector 1, the sub-shield 52 of the shield shell 20B is provided for each terminal fitting 10, and the 2 nd shield member 71 is coupled to each of the sub-shields 52, so that the respective electric wires We are individually covered with the 2 nd shield member 71. Therefore, compared to the case where the bundled electric wires We are covered with 1 braid, the connector 1 can pull out the electric wires We from the sub-shield body 52 in a flexible state, and thus can improve the degree of freedom of the wiring paths of the electric wires We. In addition, since the connector 1 does not bind the wires We together completely, the occurrence of thermal interference between the wires We is suppressed. Therefore, in the connector 1, since the increase in the diameter of each electric wire We can be suppressed, the degree of freedom of the wiring path of each electric wire We can be further improved.
In the connector 1, as described above, the wire connection portion 12 of the terminal fitting 10 is protruded from the insulating housing 20A, and the protruded wire connection portion 12 is covered with the conductive sub-shield 52. Therefore, in this connector 1, an insulator is caused to exist between the conductive wire connecting portion 12 thereof and the sub-shield body 52, and the insulating distance (spatial distance) therebetween is increased. The connector 1 includes an insulating cylindrical member (hereinafter, referred to as "insulating cylinder") 80 (fig. 3 to 5, 16, and 17) that covers the wire connecting portion 12 and the end of the wire We from the outside.
The insulating tube 80 is formed of an insulating material such as synthetic resin. The insulating cylinder 80 of this example has a square cylindrical body 81 (fig. 4, 5, 16, and 17) that accommodates the wire connecting portion 12 and the tip of the wire We inside. One end side of the cylindrical body 81 in the cylinder axis direction is inserted into the accommodating space 33 of the 1 st accommodating member 30 in a state where the wire connecting portion 12 is accommodated inside. Therefore, the terminal fitting 10 is inserted into the accommodation space 33 from the front end on the electrical connection portion 11 side through the insertion hole 34 together with the one end portion of the insulating tube 80 itself in the tube axis direction. Therefore, in the connector 1, it is preferable that the insertion hole 34 of the 1 st housing member 30 is formed in a substantially rectangular shape, and the cylindrical body 81 is formed so as to be fitted into the insertion hole 34. In the accommodating body 20A, the 2 nd accommodating member 40 is inserted into the accommodating space 33 in a state where the one end portion of the insulating cylinder 80 and the electrical connection portion 11 are accommodated in the accommodating space 33.
The insulating cylinder 80 of this example has a locking claw 82 at one end in the cylinder axial direction thereof (fig. 3, 5, 16, and 17). In this example, the locking claw 82 is provided at least at one position on one end side of the cylindrical body 81 in the cylindrical axis direction. The locking claw 82 is formed as a protrusion on the outer peripheral wall of one end side of the cylindrical body 81 and is accommodated in the accommodation space 33. The locking claws 82 can lock the edge portions of the insertion holes 34 in the outer peripheral wall 31 of the 1 st accommodating member 30 in the cylinder axis direction of the cylinder 81 accommodated in the accommodating space 33 on the one end side (fig. 3 and 17). Therefore, the locking claw 82 can temporarily hold the insulation tube 80 in the 1 st accommodation member 30 until the 2 nd accommodation member 40 is accommodated in the accommodation space 33.
Further, in the connector 1, the movement of the insulation tube 80 in the tube axis direction thereof with respect to the housing body 20A is locked by the locked portion 83 (fig. 3, 5, 16, and 17) provided in the insulation tube 80 and the locking portion 47 (fig. 10, 11, and 17) provided in the 2 nd housing member 40. The locked portions 83 and the locking portions 47 may have any shape as long as the locking described above can be performed. For example, one of the engaged portion 83 and the engaging portion 47 is formed in a protruding shape, and the other is formed in a groove shape into which the mating side is inserted. The insulating cylinder 80 of this example has a locked portion 83 at one end in the cylinder axial direction thereof. In this example, the engaged portion 83 is provided on one end side of the cylindrical body 81 in the cylindrical axis direction. The engaged portion 83 is provided as a sheet-like member protruding from one end of the cylindrical body 81 in the cylindrical axial direction. The engaged portion 83 in this example is formed in an L shape, and includes: a 1 st piece 83a projecting from one end of the cylinder 81 in the cylinder axis direction; and a 2 nd piece 83b disposed perpendicular to the 1 st piece 83a (fig. 16 and 17). The insulation tube 80 is inserted into the accommodating space 33 from the insertion hole 34 such that the direction perpendicular to the L-shaped cross section of the engaged portion 83 is oriented in the tube axis direction of the 1 st accommodating member 30. Then, the 2 nd accommodating member 40 is provided with a groove-like engaging portion 47 for accommodating the 2 nd piece portion 83b in the accommodating space 33. The locking portion 47 is a groove extending in the cylinder axial direction of the 1 st accommodating member 30 for each insulation cylinder 80, and the 2 nd piece portion 83b is inserted in the cylinder axial direction of the 1 st accommodating member 30 while the 2 nd accommodating member 40 is inserted in the accommodating space 33. The 2 nd piece portion 83b can be locked by 2 side walls (walls disposed facing each other in the cylinder axis direction of the cylinder 81) of the locking portion 47. Therefore, in the connector 1, the positional displacement of the insulating tube 80 with respect to the housing body 20A and the shield case 20B along the tube axis direction of the insulating tube 80 can be suppressed.
In the connector 1, the exterior member CB covers the 2 nd shield member 71 from the outside (fig. 1 to 5). The exterior member CB is, for example, a bellows, a shield, or the like, and is formed of an insulating material such as a synthetic resin. The exterior member CB of this example is formed as a bendable member in order to increase the degree of freedom of the wiring path of the electric wire We. For example, the exterior member CB is provided with bendable tube portions CBa, CBb (fig. 1 to 3) for each electric wire We pulled out from the holding member 20C. The exterior member CB is fixed to the shield case 20B by a binding tape CB0, for example.
In this connector 1, the 1 st accommodating member 30 is accommodated in the accommodating space 51c of the main shield 51, and the terminal fitting 10 mounted on the tip of the electric wire We and inserted into the insulating cylinder 80 is accommodated from the front end to the accommodating space 33 of the 1 st accommodating member 30. In this connector 1, the 2 nd receiving member 40 is inserted into the receiving space 33 in this state. In the connector 1, the 1 st receiving member 30, the 2 nd receiving member 40, and the shield shell 20B are screwed in order to hold these components in a fixed state. For example, in the main shield 51 of this example, a female screw portion N (fig. 12 and 14) is formed with its own cylindrical axis direction as an axis. The 1 st accommodating member 30, the 2 nd accommodating member 40, and the shield case 20B are fixed by screwing an external screw member B (fig. 5) to the internal screw portion N. The 1 st accommodating member 30 is formed with a through hole 37, and the through hole 37 is inserted with a cylindrical boss portion 51d (fig. 12 and 14) having a female screw portion N (fig. 3, 5, and 12). The 2 nd accommodating member 40 is formed with a through hole 48 (fig. 3, 5, 11, and 12) through which the male screw member B is inserted. The through holes 37 and 48 are formed with the axial direction of the outer peripheral wall 31 as the axis. The boss portion 51d has the cylindrical axial direction of the outer peripheral wall 51a as an axis. Therefore, the 1 st accommodating member 30, the 2 nd accommodating member 40, and the shield cover 20B are fastened by the axial force in the cylinder axial direction.
The connector 1 shown above is insert-fitted to the mating connector 101 as described above, and is electrically connected to the mating connector 101. Therefore, the mating connector 101 will be described below.
The mating connector 101 includes a mating terminal 110 (fig. 18 and 19) electrically connected to the terminal fitting 10. The mating terminals 110 are provided for each terminal fitting 10. The mating connector 101 of this example has 2 mating terminals 110.
The mating terminals 110 may also use themselves as contact portions. In this case, the terminal fitting (hereinafter, referred to as "mating terminal fitting") 120 itself becomes the mating terminal 110. On the other hand, the mating terminal 110 may be a terminal to which the contact member 130 is attached to the mating terminal fitting 120.
The mating terminal fitting 120 is formed in a female shape from a conductive material such as metal (copper, copper alloy, aluminum alloy, or the like). In this example, a female-type mating terminal fitting 120 is formed by a press process such as cutting or bending, using a conductive metal plate as a base material.
The mating terminal fitting 120 includes a 1 st electrical connection portion 121 and a 2 nd electrical connection portion 122 (fig. 20 and 21) which are disposed to face each other with a space therebetween. The 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 are respectively formed in a flat plate shape having 2 flat wall surfaces. In this example, the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 are respectively formed in a substantially rectangular flat plate shape. In addition, the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 of this example are formed in the same shape, respectively. In the mating terminal fitting 120, one wall surface (hereinafter, referred to as "opposing wall surface") 121a, 122a of the 2 wall surfaces of the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 are disposed to face each other with a space therebetween (fig. 20 and 21). The facing wall surfaces 121a and 122a are disposed in parallel to each other with a space therebetween.
In the counterpart terminal fitting 120, the electrical connection portion 11 is inserted between the one end portions 121b and 122b (fig. 20 and 21) of the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122, respectively, and is electrically connected to the inserted electrical connection portion 11. The 1 st electrical connection 121 and the 2 nd electrical connection 122 are formed and configured to: one of the 1 st wall surface 11a and the 2 nd wall surface 11b of the electrical connection portion 11 is disposed to face one of the facing wall surfaces 121a, 122a of the one end portions 121b, 122b, and the other of the 1 st wall surface 11a and the 2 nd wall surface 11b is disposed to face the other of the facing wall surfaces 121a, 122 a. That is, the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 are formed and configured such that: the 1 st wall surface 11a and the 2 nd wall surface 11b may be disposed to face either of the facing wall surfaces 121a and 122 a. In this example, the facing wall surfaces 121a and 122a and the 1 st and 2 nd wall surfaces 11a and 11b are arranged to face each other in a parallel state.
In the mating terminal fitting 120, when it is used as a contact with the electrical connection portion 11, contact portions (not shown) are provided in the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122, respectively. In this case, the 1 st electrical connection portion 121 is a protruding portion protruding from the opposing wall surface 121a of the one end portion 121b toward the opposing wall surface 122a of the 2 nd electrical connection portion 122 as a contact portion. Then, the 2 nd electrical connection portion 122 sets, as a contact portion, a protruding portion that protrudes from the opposing wall surface 122a of the one end portion 122b toward the opposing wall surface 121a of the 1 st electrical connection portion 121. Each contact portion has, for example, a spherical surface serving as a contact, and is disposed facing each other with a space in a direction perpendicular to the facing wall surfaces 121a and 122 a. The interval between the contact portions is narrower than the plate thickness of the electrical connection portion 11. Therefore, the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 can be brought into contact with the 1 st wall surface 11a and the 2 nd wall surface 11b of the electrical connection portion 11 by interposing the electrical connection portion 11 therebetween. Therefore, the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 are physically and electrically connected with respect to the electrical connection portions 11, respectively, in the terminal accommodating chamber 41 of the 2 nd accommodating member 40 of the housing 20.
In the mating terminal fitting 120, the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 are connected by a connection portion 123 (fig. 20 and 21). The linking portion 123 links one side end portions of the respective other end portions 121c, 122c of the 1 st and 2 nd electrical connection portions 121, 122 to each other.
The mating terminal fitting 120 includes a fixed portion 124 (fig. 20 and 21) fixed to a case 140 described later. The fixed portion 124 is provided in either one of the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122. The fixed portion 124 of this example is formed into a sheet-like body, and protrudes from an end portion in the connector inserting and extracting direction of the other end portion 122c of the 2 nd electrical connection portion 122. Here, the fixed portion 124 is projected in a direction orthogonal to the facing wall surface 122a of the 2 nd electrical connection portion 122. The fixed portion 124 is formed with a through hole 124a through which an external screw member B1 described later is inserted.
On the other hand, in the case where the contact member 130 is provided, the contact members 130 are mounted on the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122, respectively. In the present embodiment, this case is exemplified.
The contact member 130 may be different members for the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122, or may be a common member for the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122. Here, the contact member 130 is shared between the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122.
The contact member 130 is physically and electrically connected to the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122, respectively, by being mounted on the one end portions 121b and 122b of the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122, respectively. That is, the mating terminal 110 includes: a combination of a pair of the 1 st electrical connection portions 121 and one contact member 130 in a contact state with each other; and a combination of the pair of 2 nd electrical connection portions 122 and the other contact member 130 which are in a contact state with each other. Based on this, the contact member 130 can be brought into contact with the 1 st wall surface 11a or the 2 nd wall surface 11b of the electrical connection portion 11 that has been inserted between the one end portions 121b, 122b of the 1 st and 2 nd electrical connection portions 121, 122. Therefore, the contact member 130 can electrically connect the electrical connection portion 11 with the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122.
The contact member 130 is formed of a conductive material such as metal (copper, copper alloy, aluminum alloy, or the like) so as to have elasticity. In this example, the contact member 130 is formed by pressing a conductive metal plate as a base material, such as cutting or bending.
The contact member 130 is shaped so that the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 are embedded. Therefore, the contact member 130 is formed in a ring shape or a cylindrical shape. For example, the contact member 130 of this example has: 2 square cylindrical annular portions 131 that are aligned in the cylindrical axis direction and are disposed facing each other with a space therebetween; and 4 coupling portions 132 that couple the annular portions 131 (fig. 20 and 21). One end 121b of the 1 st electrical connection portion 121 and one end 122b of the 2 nd electrical connection portion 122 are fitted inside the annular portions 131. Each of the coupling portions 132 is disposed at a corner of each of the 2 annular portions 131, for example, and couples corners facing each other in the cylindrical axis direction.
Further, the contact member 130 has at least one contact portion 133 between the annular portions 131, and the contact portion 133 protrudes outward from each annular portion 131 and has elasticity (fig. 20 and 21). The contact member 130 of this example has a plurality of contact portions 133 protruding in the same direction by the same protruding amount. The contact portion 133 connects both ends in the cylinder axial direction to the respective annular portions 131, and has a curved surface provided at the maximum projecting position at the center in the cylinder axial direction as a contact. The contact portions 133 form a virtual plane (not shown) by connecting the maximum protruding positions to each other. The virtual plane in this example is disposed to face each other in parallel to the facing wall surfaces 121a and 122a when the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 are embedded.
In the mating connector 101, the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 are fitted into the contact members 130 so that the imaginary planes are arranged to face each other with a space therebetween in a state of being parallel to each other. In this way, the contact portions 133 of the contact members 130 are arranged to face each other in a direction orthogonal to the facing wall surfaces 121a and 122a of the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122, respectively. The interval between the respective imaginary planes is narrower than the plate thickness of the electrical connection portion 11. Therefore, in each of the contact members 130, by interposing the electrical connection portion 11 therebetween, each of the contact portions 133 can be brought into contact with the 1 st wall surface 11a and the 2 nd wall surface 11b of the electrical connection portion 11. Therefore, the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 are physically and electrically connected to the electrical connection portion 11 via the contact members 130, respectively, in the terminal accommodating chamber 41 of the 2 nd accommodating member 40 of the housing 20.
Here, in the case where the contact member 130 is provided, the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122 may or may not have the contact portion (projection) described above, respectively. In the case of having the contact portion (the convex portion), the mating connector 101 can realize the sharing of the mating terminal fitting 120 regardless of the presence or absence of the contact member 130. Here, no contact portion (projection) is provided at the 1 st electrical connection portion 121 and the 2 nd electrical connection portion 122.
The mating connector 101 includes a housing 140 (fig. 1, 18, and 19) that accommodates the mating terminal 110. The case 140 has: a receiving member 150 that receives the mating terminals 110 (fig. 1, 18, and 19); and a holding member 160 that prevents the accommodated mating terminals 110 from coming off the accommodating member 150 (fig. 18 and 19).
The housing member 150 is molded from an insulating material such as synthetic resin. The accommodating member 150 includes: a 1 st accommodating body 151 accommodating a combination of a pair of the 1 st electrical connection portions 121 and one contact member 130; and a 2 nd accommodating body 152 accommodating a combination of the pair of 2 nd electrical connection portions 122 and the other contact member 130 (fig. 1, 18, and 19). The 1 st housing 151 is formed to surround the 1 st electrical connection portion 121 and the one contact member 130 in a state where the facing wall surface 121a and the contact portion 133 side of the one contact member 130 are exposed. The 2 nd accommodating body 152 is formed so as to surround the 2 nd electrical connection portion 122 and the other contact member 130 in a state where the opposing wall surface 122a and the contact portion 133 side of the other contact member 130 are exposed. The 1 st housing 151 and the 2 nd housing 152 are disposed facing each other with a space in a direction orthogonal to the facing wall surfaces 121a and 122 a. The distance is set to a size that does not prevent the electrical connection portion 11 from being inserted between the contact members 130. The receiving part 150 is provided with the pair of the 1 st receiving body 151 and the 2 nd receiving body 152 for each counterpart side terminal 110.
The housing member 150 has a cylindrical body 153 (fig. 1, 18, and 19) having a connector insertion/removal direction as a cylindrical axis direction and having both ends open in the cylindrical axis direction. All the combinations of the 1 st receiving body 151 and the 2 nd receiving body 152 extend from the inner space of the cylinder 153 toward the connector insertion direction, and protrude from the opening 153a of one end of the cylinder 153 (fig. 1 and 18). The opening 153b at the other end of the cylindrical body 153 is provided with an insertion port 153c (fig. 19) for inserting the mating terminal 110 for each mating terminal 110. Further, the 1 st housing 151 and the 2 nd housing 152 are held inside the cylinder 153, and a holding portion 153d (fig. 19) for holding the mating terminal 110 is provided. The mating terminal 110 is fixed to the holding portion 153d via the outer screw member B1 inserted through the through hole 124 a. A female screw member N1 (fig. 19) for screwing the male screw member B1 is inserted and fitted into the holding portion 153 d.
The housing member 150 has a flange portion 154 (fig. 1, 18, and 19) on the outer side of the cylindrical body 153 for attachment to the case 201 of the power supply circuit 200. The flange portion 154 has a through hole 154a (fig. 22) through which the male screw member B2 is inserted, and is fixed to the case 201 (fig. 1) via the male screw member B2. A female screw portion N2 (fig. 22) for tightening the male screw member B2 is formed in the case 201.
In the cylindrical body 153, a fitting portion (connector fitting portion) 153e (fig. 1, 18, and 19) with the connector fitting portion 31a of the housing 20 of the connector 1 is formed on the connector insertion direction side (that is, a portion protruding from the housing 201) with respect to the flange portion 154. An annular seal member Se11 is attached to the outer peripheral surface of the connector fitting portion 153 e. The connector fitting portion 153e is inserted and fitted inside the connector fitting portion 31 a. The sealing member Se11 is present between the connector fitting portion 31a and the connector fitting portion 153e, and is in close contact with both wall surfaces. On the other hand, the cylindrical body 153 is a fitting portion 153f (fig. 18 and 19) with the holding member 160 on the connector removal direction side (that is, a portion embedded in the housing 201) of the flange portion 154.
The holding member 160 is molded from an insulating material such as a synthetic resin. The holding member 160 is fitted to the fitting portion 153f on the opening 153b side of the other end of the cylindrical body 153, and closes the insertion port 153c of the mating terminal 110. The holding member 160 is inserted and fitted with the fitting portion 153f inside. The holding member 160 is a fitting portion with the housing 201 in the mating connector 101. Therefore, an annular seal member Se12 (fig. 18 and 19) is attached to the outer peripheral surface of the holding member 160.
The mating connector 11 has such a configuration.
The connector 1 is inserted and fitted into the mating connector 101 as described above, and thereby electrically connected to the mating connector 101 (fig. 23 and 24). The connector 1 of the present embodiment is fastened to the mating connector 101 with screws in order to maintain a fitted state with the mating connector 101 (that is, an electrical connection state with the mating connector 101). In this example, as described above, the shield cover 20B is screw-fastened to the housing 201 via the coupling body 53 in a connector fitting state, whereby the connector 1 is fixed to the mating connector 101 side. Here, the connector 1 can electrically connect the shield cover 20B and the housing 201 to each other by bringing the shield cover 20B into contact with the housing 201 by the screw fastening, or electrically connect the shield cover 20B and the housing 201 via a conductive screw member. Note that the case 201 is grounded (grounded).
The connecting body 53 is formed to be screwed to the housing 201 in a connector fitting state. The connecting member 53 may be in contact with the wall surface 201a of the housing 201 in the connector fitting state, or may be in contact with the wall surface 201a of the housing 201 in the floating state without being in contact with the wall surface. In this example, as shown in the latter, the coupling body 53 and the case 201 are not brought into direct contact with each other.
In the coupling body 53, the case 201 is screwed between the adjacent 2 sub-shielding bodies 52 arranged side by side. Between the sub-shields 52, the male screw portion B0a of the conductive male screw member B0 used for screw fastening is disposed. The connecting body 53 of this example has a fixing portion 53a (fig. 24) used for fastening the screw. Therefore, the fixing portion 53a is disposed between the adjacent 2 sub-shielding bodies 52 disposed side by side. Then, a through hole 54 (fig. 3 and 24) used for fastening the screw is formed in the fixing portion 53 a. The through hole 54 is a hole through which the male screw portion B0a of the male screw member B0 is inserted, and has an axis in a direction perpendicular to the wall surface 201a of the case 201. Between the adjacent 2 sub-shield bodies 52 arranged side by side, the male screw portion B0a of the male screw member B0 is arranged along the axis.
Here, the male screw member B0 may be screwed to a female screw portion formed in the case 201, or may be provided so as to hang from the wall surface 201a of the case 201 like a stud bolt. When the fixing portion 53a is a member for fastening the male screw member B0 to the female screw portion of the case 201, the fixing portion has a seat surface 53a with which the head of the male screw member B0 comes into contact in the fastened state1(FIG. 24). On the other hand, when the outer screw member B0 is hung from the case 201, the conductive inner screw member is screwed to the outer screw member B0. The fixing portion 53a in this case has a seat surface 53a with which the inner screw member comes into contact in this tightened state1(FIG. 24). In this example, the case 201 is formed with a female screw portion N0 (fig. 1, 22, and 24). Therefore, the fixing portion 53a of this example has a seat surface 53a with which the head portion B0B of the external screw member B0 comes into contact1(FIG. 24).
The fixing portion 53a is formed by arranging a seat surface 53a between adjacent 2 sub-shielding bodies 52 arranged side by side1. In view of this, in the shield case 20B, the head B0B (an inner screw member in the case of using the inner screw member) of the screw-fastened outer screw member B0 is arranged at a position where it is not easily visible to the eyes. Therefore, in the connector 1, it is possible to prevent a worker (a user of the vehicle or the like) who does not grasp the connector 1 from inserting a tool into the head portion B0B and easily releasing the screw fastening. This effect can be obtained equally as compared with the case where the inner screw member is used.
In order to enhance such an effect, for example, it is preferable that the fixing portion 53a is formed closer to the case 201 than the cylindrical shafts of the respective adjacent 2 sub-shields 52 arranged side by sideThe wall surface 201a is provided with a seat surface 53a1. Accordingly, in the shield case 20B, the head portions B0B (inner screw member in the case of using the inner screw member) of the screwed outer screw members B0 can be arranged between the adjacent 2 sub-shield bodies 52 arranged side by side without protruding from the respective sub-shield bodies 52. Therefore, in the connector 1, the head B0B after the screw fastening is less visible than in the case where the head B0B is disposed by protruding from each sub-shield 52 and screwing the head B0B to the edge of the shield shell 20B. Therefore, in the connector 1, the effect of suppressing the screw fastening from being easily released by a worker who does not grasp the attachment/detachment work of the connector 1 can be enhanced. Such an effect can be obtained equally even when the inner screw member is used.
Further, for example, it is preferable that the fixing portion 53a has a seating surface 53a formed so that the head portion B0B (an internal screw member in the case of using the internal screw member) of the external screw member B0 is arranged closer to the wall surface 201a of the case 201 than the cylindrical shaft (the cylindrical shaft of each of the adjacent 2 sub-shields 52 arranged side by side)1. Accordingly, in the shield case 20B, the head B0B (the inner screw member in the case of using the inner screw member) of the outer screw member B0 screwed between the adjacent 2 sub shield bodies 52 arranged side by side can be arranged at a deep position on the wall surface 201a side. Therefore, in the connector 1, the head B0B after the screw fastening becomes less visible, and the screw fastening can be more appropriately suppressed from being easily released. Such an effect can be obtained equally even when the inner screw member is used.
Further, the seating surface 53a1It is preferably disposed as close as possible to the wall surface 201a of the case 201 within a range in which it can be formed. Accordingly, in the shield case 20B, the head B0B (the inner screw member in the case of using the inner screw member) of the outer screw member B0 after the screw fastening can be disposed at the deepest position on the wall surface 201a side between the adjacent 2 sub shield bodies 52 arranged side by side. Therefore, in the connector 1, the head B0B after the screw fastening is least visible, and the easy release of the screw fastening can be suppressed to the best. In useIn the case of the screw member, such an effect can be obtained equally.
Here, the seating surface 53a1The outer peripheral wall 51a of the main shield 51 is preferably disposed adjacent to the outer peripheral wall 51 a. Accordingly, in the shield case 20B, the head B0B (inner screw member in the case of using the inner screw member) of the screw-fastened outer screw member B0 is surrounded not only by the adjacent 2 sub-shields 52 arranged side by side but also by the outer peripheral wall 51a of the main shield 51. Therefore, in the connector 1, since the visibility of the head B0B after the screw fastening can be further reduced, the easy release of the screw fastening can be further suppressed. Such an effect can be obtained equally even when the inner screw member is used.
Specifically, in this example, the fixing portion 53a is formed as a sheet-like portion of a sheet-like body, and the seat surface 53a is formed1Is provided on a plane opposite to the plane disposed to face the wall surface 201a of the case 201. In the outer screw member B0 of this example, an engagement member R such as a C-ring is attached to the screw portion B0a side so that the fixing portion 53a of the sheet-like body is present between the fixing portion and the head portion B0B (fig. 1 and 24). The head B0B and the locking member R sandwich the fixing portion 53a so that the outer screw member B0 automatically pivots around the axis, and hold the outer screw member B0 at the fixing portion 53 a.
In this example, the male screw member B0 is screwed to the female screw portion N0 in a state where fitting of the connector 1 to the mating connector 101 is completed. Accordingly, the connector 1 can maintain a fitted state with the mating connector 101 (an electrically connected state with the mating connector 101), and can electrically connect the 1 st shield member (shield cover 20B) and the 2 nd shield member 71 with the housing 201, thereby exhibiting shielding performance. Then, the connector 1 is configured by arranging the seat surface 53a of the fixing portion 53a as described above1Accordingly, the screw fastening by the external screw member B0 and the internal screw portion N0 can be prevented from being easily released, and therefore, the fitted state between the connector 1 and the mating connector 101 can be prevented from being easily released by a user of the vehicle or the like. Therefore, the connector 1 can suppress occurrence of the disconnection when the connector 1 and the mating connector 101 are fitted againThe shielding performance can be continuously exhibited in a situation where a skilled vehicle user forgets to perform screw fastening or the like.
A cylindrical operation space 53B is formed in the coupling body 53, and the operation space 53B is used for inserting a tool (not shown) such as a socket wrench into the head B0B and for pivoting the head B0B with the tool (fig. 1, 13, 15, and 24).
However, in the connector 1 of the present embodiment, in order to more reliably suppress the screw fastening from being easily released, the insertion of a tool into the head B0B (the inner screw member in the case of using the inner screw member) of the screw-fastened outer screw member B0 is physically avoided. To embody this, in this connector 1, one of the adjacent 2 sub-shielding bodies 52 arranged side by side is provided with a moving member 91 (fig. 1 to 5, 13 to 15, and 23 to 29) that is relatively movable along the outer peripheral wall 52c thereof between the retreat position and the prevention position.
The retracted position is a position (fig. 1 to 5, 15, 23, 25, and 28) at which a tool can be inserted into the head B0B (an inner screw member in the case of using an inner screw member) of the outer screw member B0 after the screw fastening. In the connector 1, when the moving member 91 is located at the retracted position, a tool can be inserted into the head B0B of the screwed male screw member B0, and the state of screwing the male screw member B0 to the female screw portion N0 can be released. On the other hand, the prevention position is a position where a tool cannot be inserted into the head B0B (an inner screw member in the case of using the inner screw member) of the outer screw member B0 after the screw fastening (fig. 24, 26, 27, and 29). In the connector 1, when the moving member 91 is at the prevention position, since the moving member 91 obstructs the insertion of the tool, the tool cannot be inserted into the head B0B of the screw-fastened male screw member B0, and the state of the male screw member B0 tightened to the female screw portion N0 cannot be released.
In the connector 1, after the connector 1 is screwed to the housing 201, the moving member 91 is relatively moved to the prevention position. Accordingly, in the connector 1, the moving member 91 must be relatively moved to the retracted position, and the screw fastening of the connector 1 to the housing 201 can be released. Therefore, if the operator is a worker who grasps the attachment/detachment operation of the connector 1, the screw fastening of the connector 1 to the housing 201 can be released by relatively moving the moving member 91 from the prevention position to the retreat position. On the other hand, the movement member 91 for preventing the position can make a worker (a user of the vehicle or the like) who does not grasp the attaching and detaching work hesitate to easily release the screw stopper. Therefore, in the connector 1, it is possible to prevent a worker who does not grasp the attachment/detachment work process from easily releasing the screw fastening.
Specifically, the moving member 91 has a base 91a, and the base 91a is attached to the outer peripheral wall 52c of the sub-shield 52 to be mounted so as to be relatively movable (fig. 1, 4, 5, 13, 14, 23, and 25 to 29). The moving member 91 of this example is formed to relatively rotate along the circumferential direction of the sub-shield 52 between the retreat position and the prevention position. Therefore, the base 91a is formed in an arc shape and is fitted concentrically and relatively rotatably into the outer peripheral wall 52c of the sub shield body 52.
Further, the moving member 91 has a cap portion 91B, and the cap portion 91B covers the head portion B0B (an inner screw member in the case of using the inner screw member) of the screw-fastened outer screw member B0 (fig. 1, 4, 5, 13 to 15, 23, and 25 to 29). In the prevention position, the cap 91B is disposed on the insertion trajectory of the head B0B (inner screw member in the case of using the inner screw member) of the outer screw member B0 after the tool is fastened to the screw. The cover 91b protrudes radially outward from the base 91 a. The lid 91b is formed such that: the tool can be retracted to a position apart from the insertion path of the tool at the retracted position, and is disposed on the insertion path of the tool at the prevention position. Therefore, when the moving member 91 is at the retracted position, the tool can be inserted into the head B0B (the inner screw member in the case of using the inner screw member) of the screw-fastened outer screw member B0. On the other hand, since the cap 91B obstructs the insertion of the tool when the moving member 91 is in the prevention position, the tool cannot be inserted into the head B0B (inner screw member when the inner screw member is used) of the outer screw member B0 to which the screw is fastened. In this example, the cover 91b of the rectangular sheet-like body is projected outward in the radial direction from one circumferential end of the base 91 a. Then, at the prevention position, the cover 91b is disposed in the cylindrical operation space 53b of the tool.
The moving member 91 has flexibility at least at the base portion 91 a. The moving member 91 is molded from, for example, a synthetic resin.
Here, 2 guide portions 57 are provided on the outer peripheral wall 52c of the sub-shield 52 to which the moving member 91 is attached, and the guide portions 57 guide the relative rotation of the moving member 91 in the circumferential direction and lock the relative movement of the moving member 91 in the cylindrical axial direction (fig. 1, 3, 13 to 15, 23, and 25 to 29). The guide portions 57 are disposed facing each other with a space therebetween in the cylinder axis direction. The one guide portion 57 is a portion for guiding and locking one end portion in the axial direction of the base portion 91a of the moving member 91, and locks an end surface and an outer peripheral surface in the axial direction of the one end portion. The other guide portion 57 is a portion for guiding and locking the other end portion in the axial direction of the base portion 91a of the moving member 91, and locks an end surface and an outer peripheral surface in the axial direction of the other end portion. The guide portion 57 of this example is formed in an L shape protruding radially outward from the outer peripheral wall 52c and protruding in the cylinder axial direction of the outer peripheral wall 52c from the end on the protruding direction side. The base portion 91a of the moving member 91 has notch portions 91c at both ends in the axial direction (fig. 13, 14, 23, and 26). The moving member 91 is attached to the outer peripheral wall 52c of the sub-shield 52 to be attached so as to be movable relative thereto by inserting the guide portions 57 into the notches 91 c. Each cutout 91c is formed so as to be disposed closer to the prevention position side than each guide portion 57 in the circumferential direction when in the retracted position (fig. 23 and 26).
Further, a retraction holding mechanism M1 (fig. 28) for holding the moving member 91 at the retraction position is provided between the moving member 91 and the sub shield 52 to which the moving member 91 is attached. In the present figure, for convenience of explanation, only the shield case 20B and the moving member 91 are shown. The retraction-time holding mechanism M1 includes: a protruding portion 91d protruding radially inward from the inner peripheral surface of the base portion 91a (fig. 14 and 28); and groove 52c1The projection 91d is inserted into the outer peripheral wall 52c of the sub-shield 52 to be mounted at the retracted position (fig. 13 and 28).
The protrusion 91d and the groove 52c1The protrusion 91d is formed so as to be able to pass through the groove 52c when the moving member 91 is relatively rotated from the retracted position to the prevention position with respect to the sub-shield 521And (4) disengaging. Therefore, the protrusion 91d and the groove 52c1An end surface 91d of the cover 91b side in the circumferential direction1、 52c11Inclined with respect to the radial and circumferential directions, respectively (fig. 28). On the other hand, the protrusion 91d and the groove 52c1The moving member 91 is not rotated relative to the sub-shield 52 in the direction opposite to the prevention position side from the retracted position. Therefore, the protrusion 91d and the groove 52c1An end surface 91d set to be opposite to the cover 91b side in the circumferential direction2、52c12Formed in the radial direction, and the end face 91d2、52c12Are locked with each other (fig. 28).
In the connector 1, since the moving member 91 can be held at the retracted position by the retracted holding mechanism M1, the reduction in operability can be suppressed when the screw fastening operation of the outer screw member B0 is performed.
Further, a preventing time holding mechanism M2 (fig. 29) for holding the moving member 91 at a preventing position is provided between the moving member 91 and the sub shielding body 52 to which the moving member 91 is attached. In the present figure, for convenience of explanation, only the shield case 20B and the moving member 91 are shown. Here, the cylindrical operation space 53b of the tool partially cuts the outer peripheral wall 52c of the sub-shield 52 on the relative rotation locus of the moving member 91. Therefore, the outer peripheral wall 52c has a wall surface 53b which is in the relative rotation locus with the operation space 53b1Intersecting corner 52c2(fig. 13, 28, and 29). The time-prevention holding mechanism M2 of this example uses this corner portion 52c2 and the protruding portion 91d of the moving member 91. In the preventing-time holding mechanism M2, the protrusion 91d is caused to intrude into the operation space 53b and the protrusion 91d is caused to be locked in the circumferential direction at the corner 52c simultaneously with the relative rotation of the moving member 91 to the preventing position2Wall surface 53b of operation space 53b1. Base ofIn this case, the prevention-time holding mechanism M2 can hold the moving member 91 at the prevention position.
In the moving member 91, since the base portion 91a has flexibility, the operator can pull out the protruding portion 91d from the operation space 53b by bending the lid portion 91b side of the base portion 91a outward in the radial direction. Therefore, the moving member 91 can also perform relative rotation from the prevention position to the retracted position.
In the connector 1, since the moving member 91 can be held at the prevention position by the prevention-time holding mechanism M2, the cover portion 91b can be continuously disposed on the insertion trajectory of the tool at the prevention position. Therefore, the connector 1 can keep suppressing the operator who does not grasp the mounting/dismounting operation process from easily releasing the screw fastening.
As described above, in the connector 1 and the connector-equipped electric wire WH according to the present embodiment, since the head portion B0B (the inner screw member in the case of using the inner screw member) of the outer screw member B0 after screw tightening is disposed at a position where it is not easily visible to the eye, it is possible to prevent a worker (such as a vehicle user) who does not grasp the connector 1 from easily releasing the screw tightening. Further, in the connector 1 and the connector-equipped electric wire WH of the present embodiment, since the moving member 91 is provided so that the head B0B (the inner screw member in the case of using the inner screw member) of the outer screw member B0 to which the screw is fastened cannot be inserted with a tool, it is possible to prevent a worker (such as a user of a vehicle) who does not grasp the attachment/detachment work process of the connector 1 from easily releasing the screw fastening. Therefore, in the connector 1 and the connector-equipped electric wire WH according to the present embodiment, since the chance that those persons will unintentionally detach the mating connector 101 from the mating connector 101 can be reduced, the screw-fastened state to the housing 201 can be maintained, and the desired shielding performance can be continuously maintained.
However, in the previous example, the moving member 91 that rotates relatively in the circumferential direction with respect to the outer circumferential wall 52c of the sub-shield 52 is shown. In the connector 1, the following moving member 92 (fig. 30 to 34) may be used instead of the moving member 91. The moving member 92 is formed to move relatively in the cylindrical axis direction of the sub-shield 52 between the retreat position and the prevention position. Here, the retracted position is shown in fig. 31 and 32, and the prevention position is shown in fig. 33 and 34. The moving member 92 includes a base portion 92a and a cover portion 92b similar to the moving member 91.
The connector 1 also includes a retraction holding mechanism M1 and a prevention holding mechanism M2, as in the case of using the moving member 91. The outer peripheral wall 52c of the sub-shield 52 to which the moving member 92 is attached is provided with a 1 st projecting portion 58 and a 2 nd projecting portion 59 (fig. 30 to 34) which are disposed to face each other with a space in the cylinder axis direction. Here, the 1 st projection 58 is disposed on the opening 52a side, the 2 nd projection 59 is disposed on the main shield 51 side, and the 1 st projection 58 and the 2 nd projection 59 constitute the retreat holding mechanism M1 and the prevention holding mechanism M2. Here, the case where the moving member 92 is disposed closer to the opening 52a than the 1 st protruding portion 58 is defined as the retracted position (fig. 31 and 32), and the case where the moving member 92 is inserted between the 1 st protruding portion 58 and the 2 nd protruding portion 59 is defined as the prevention position (fig. 33 and 34).
In the retracted position, the 1 st projecting portion 58 serves as a retracted holding mechanism M1, and the 1 st projecting portion 58 locks the movement of the base portion 92a of the moving member 92 toward the prevention position. In this example, when the moving member 92 is relatively moved from the retracted position to the prevention position, the end surface 58a on the opening 52a side of the 1 st protruding portion 58 is inclined so that the base portion 92a can get over the 1 st protruding portion 58 (fig. 30 to 34).
On the other hand, in the prevention position, the 1 st protruding portion 58 and the 2 nd protruding portion 59 become the prevention-time holding mechanism M2, and the 1 st protruding portion 58 and the 2 nd protruding portion 59 sandwich the base portion 92a of the moving member 92 inserted between the 1 st protruding portion 58 and the 2 nd protruding portion 59 in the cylinder axis direction.
At least the base portion 92a of the moving member 92 is also flexible. Therefore, in the moving member 92, the operator can pull out the base portion 92a from between the 1 st protruding portion 58 and the 2 nd protruding portion 59 by bending the cover portion 92b side of the base portion 92a radially outward. Therefore, the moving member 92 can also perform relative movement from the prevention position to the retracted position.
The moving member 92 restricts relative rotation with respect to the outer peripheral wall 52c of the sub-shield 52 by locking the other end portion opposite to the one end portion having the cover 92b to the connecting body 53 in the circumferential direction (fig. 35). The relative rotation can be restricted at both the retreat position and the prevention position. In this figure, an example of the prevention position is described.
Even when the connector 1 and the connector-equipped electric wire WH of the present embodiment use the moving member 92, the same effects as those of the moving member 91 described above can be achieved.
