Description

  The present invention relates to a connector.

  Conventionally, as a connector, a housing chamber in which a connection portion between a terminal and an electric wire is accommodated is provided inside the housing, and the housing chamber is filled with a waterproof filler, thereby waterproofing the connection portion. The thing which raised the property is known. For example, this type of connector is disclosed in Patent Document 1 below. In the connector of Patent Document 1, a seal cap (water stop member) is further provided so that the filler does not flow out from the electric wire outlet of the housing. The seal cap is formed in an annular shape with a flexible material having elasticity such as rubber, and the electric wire is inserted into the inside of the cap, and is sandwiched between the semicircular arc-shaped wall surfaces of the housing and the rear holder forming the housing. Make it. In this connector, the seal cap has an inner peripheral surface closely attached to the outer peripheral surface of the electric wire over the entire circumference, and an inner peripheral surface (housing and rear holder) at the electric wire outlet of the housing over the entire outer peripheral surface. Are formed by being sandwiched between the semi-arc-shaped wall surfaces of the semi-arc-shaped wall surfaces.

JP 2014-179192 A

  However, when the seal cap is deformed, the seal cap depends on the sandwiched state between the semicircular wall surface of the housing and the semicircular wall surface of the rear holder. The degree of adhesion to the peripheral surface is not always desired over the entire circumference. For this reason, the conventional connector has room for improvement in suppressing the outflow of the filler from the wire outlet.

  Therefore, an object of the present invention is to provide a connector having a high effect of suppressing the outflow of the filler.

  In order to achieve the above object, the present invention provides a terminal connection portion that is physically and electrically connected to a counterpart terminal of a counterpart connector, and a wire connection portion that is physically and electrically connected to a wire. A terminal including the terminal, an annular liquid-stopping member through which the electric wire is inserted inward, a first storage chamber in which at least a part of the terminal connection portion of the terminal is stored, and the terminal together with the connected electric wire The second storage chamber in which the wire connection portion is stored, the third storage chamber in which the outer peripheral surface of the liquid stop member is fitted, and the electric wire connected to the wire connection portion passes through the inside of the liquid stop member. And a liquid-proof member formed by filling the second storage chamber with a liquid filler, and the liquid-stopping member includes the third liquid-retaining member. The third storage chamber over the entire circumference of the outer peripheral surface fitted in the storage chamber An annular resin body that is in close contact with the inner peripheral surface, an inner peripheral surface that is in close contact with the outer peripheral surface of the electric wire, and an outer peripheral surface that is in close contact with the inner peripheral surface of the resin body over the entire periphery And an annular elastic body.

  Here, it is desirable that the liquid stopping member is an integrally molded product of the resin body and the elastic body.

  The housing communicates with the second housing chamber by assembling the first housing member having a semi-arc-shaped first semi-arc-shaped wall surface communicated with the second housing chamber and the first housing member. A second housing member having a second semi-arc-shaped wall surface, and the first housing member and the second housing member are assembled to each other to assemble the first semi-arc-shaped wall surface and the second housing member. A columnar space formed by a second semi-arc-shaped wall surface, comprising a wire lead-out portion for guiding the wire in the second storage chamber to the wire outlet, wherein the first housing member is the first half member. The arcuate wall surface has a semicircular first semicircular recess, the second housing member has a semicircular second semicircular recess on the second semicircular wall surface, and the housing includes the first semicircular recess. Forming the first semi-annular recess and the second semi-annular recess by assembling the housing member and the second housing member together. It is desirable to have annular recesses and the third accommodating chamber.

  In the connector according to the present invention, since the liquid stop member is composed of the outer resin body and the inner elastic body in the radial direction, the liquid stop member consisting only of the resin body or the liquid stop member consisting only of the elastic body is applied. Compared with the case where it is made, the elastic body is easy to follow the change of the shape of the electric wire. For this reason, since this connector can improve the outflow suppression effect of the filler from between the inner peripheral surface of the liquid-stopping member and the outer peripheral surface of the electric wire, the liquid filler in the second storage chamber is moved outward. Can be suppressed.

  Hereinafter, embodiments of a connector according to the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited by this embodiment.

[Embodiment]
One embodiment of a connector according to the present invention will be described with reference to FIGS.

  Reference numeral 1 in FIGS. 1-4 indicates the connector of the present embodiment. This connector 1 is a so-called waterproof connector. The connector 1 includes a terminal 10 and a housing 20 that houses and holds the terminal 10. The illustrated case 20 is an assembly in which a plurality of case members (a housing 30, a rear holder 40, a front holder 50, and a shell 60), which will be described later, are assembled together.

  The terminal 10 is formed of a conductive material such as metal. For example, the terminal 10 is formed into a predetermined shape by press forming such as bending or cutting for a metal plate as a base material. The terminal 10 is physically and electrically connected to a terminal connection portion 11 that is physically and electrically connected to a counterpart terminal (not shown) of a counterpart connector (not shown) and an electric wire 70. And a wire connecting portion 12 (FIGS. 3 and 4).

  The terminal connecting portion 11 is formed into a female type into which a male counterpart terminal is inserted and fitted, or a male type to be inserted into and fitted into a female counterpart terminal. In the present embodiment, the terminal connection portion 11 is formed in a male shape so that the terminal 10 becomes a male terminal. Here, a single-piece terminal connecting portion 11 extending in the insertion / extraction direction between the connector 1 and the counterpart connector (hereinafter referred to as “connector insertion / extraction direction”) is formed. The electric wire connection part 12 is formed so that the core wire 71 (FIG. 4) of the terminal of the electric wire 70 may be connected physically and electrically. The connection is made by crimping or welding. In this embodiment, two barrel pieces are provided in the electric wire connection portion 12, and each barrel piece is crimped to the exposed core wire 71, thereby crimping the electric wire connection portion 12 to the core wire 71.

  The terminal 10 is formed in an L-shape in which the terminal connection portion 11 and the wire connection portion 12 intersect (here, orthogonal). For this reason, in this exemplary terminal 10, the electric wire 70 is extended from the electric wire connection part 12 in the orthogonal direction with respect to the connector insertion / extraction direction.

  The casing 20 is formed of an insulating material such as synthetic resin. The housing 20 is formed by assembling four housing members together. Here, a housing 30 as a first housing member, a rear holder 40 as a second housing member, a front holder 50 as a third housing member, and a shell 60 as a fourth housing member are provided. (FIGS. 3 and 4). The illustrated case 20 is formed so that three sets of a pair of terminals 10 and electric wires 70 are accommodated side by side.

  The housing 20 includes a first storage chamber 21 (FIG. 3) in which at least a part of the terminal connection portion 11 of the terminal 10 is stored, and a first connection chamber 12 in which the wire connection portion 12 of the terminal 10 is stored together with the connected electric wire 70. 2 storage chambers 22 (FIGS. 4 and 5) are provided for each terminal 10. Furthermore, this housing | casing 20 also has the storage chamber (3rd storage chamber 23) of the liquid stop member 90 mentioned later for every terminal 10 (FIG.3 and FIG.6). Moreover, this housing | casing 20 has the fitting part 24 fitted to the housing | casing (not shown) of an other party connector, and the electric wire outlet 25 from which the electric wire 70 connected to the electric wire connection part 12 is pulled out outward. And a wire lead-out portion 26 for guiding the wire 70 in the second storage chamber 22 to the wire outlet 25 (FIG. 3).

  The first storage chamber 21 may be formed so that the free end of the terminal connection portion 11 is accommodated in the room, and is formed so that the front end protrudes from the room. May be. The illustrated first accommodating chamber 21 is the latter, and is formed so that the single-piece terminal connecting portion 11 is inserted and held. The first accommodating chamber 21 extends in the connector insertion / extraction direction, and both ends in the extending direction are opened. In the first storage chamber 21, one opening opens to the counterpart terminal side, and the other opening opens to the second storage chamber 22. The terminal connection part 11 is inserted from the opening on the second housing chamber 22 side, and protrudes from the opening on the counterpart terminal side toward the counterpart terminal side. Three first storage chambers 21 are formed in the housing 30. Each first storage chamber 21 is arranged such that the terminal connection portions 11 of the respective terminals 10 are arranged on the same plane.

  The housing 30 is provided with a fitting portion 24 so as to surround the three first accommodation chambers 21. The illustrated fitting portion 24 is fitted inside the cylindrical portion of the housing of the mating connector. The fitting portion 24 is formed in a columnar body such as a prismatic shape or a racetrack shape, for example, and the column axis direction is arranged in accordance with the connector insertion / extraction direction. The three first storage chambers 21 are formed inside the fitting portion 24. An annular packing 39 is attached to the outer peripheral surface of the fitting portion 24. The packing 39 is also in close contact with the inner peripheral surface of the cylindrical portion of the housing of the mating connector, and improves the liquid tightness between the connector 1 and the mating connector. Note that the illustrated fitting portion 24 has a cylindrical portion such that its outer peripheral surface extends to the counterpart connector side.

  A front holder 50 is fitted to the outer peripheral surface of the fitting portion 24. The front holder 50 is formed as a cylindrical body whose one end is closed, and is formed so that its inner peripheral surface is fitted to the outer peripheral surface of the fitting portion 24. The front holder 50 is fitted into the fitting portion 24 from the counterpart connector side, and its outer peripheral surface is fitted to the counterpart connector together with the outer peripheral surface of the fitting portion 24. For this reason, in the illustrated case 20, the outer peripheral edge portion of the front holder 50 substantially forms a fitting portion 24 for the mating connector (FIGS. 3 and 4). The closed wall surface 51 at one end of the front holder 50 is formed with a through hole 51a for inserting and holding the terminal connecting portion 11 for each terminal 10 (FIG. 3). The terminal connecting portion 11 is projected from the through hole 51a toward the counterpart terminal side.

  The second storage chamber 22 is formed using a space surrounded by the housing 30, the rear holder 40 and the shell 60.

  A housing groove 31 for forming the second housing chamber 22 is formed in the housing 30 for each terminal 10 (FIGS. 4 and 5). The illustrated accommodation groove 31 is formed in a rectangular shape, and the electric wire connection portion 12 is accommodated therein. The wall surface on the second storage chamber 22 side in the fitting portion 24 of the first storage chamber 21 is used as the wall surface 31a on the counterpart terminal side of the storage groove 31 (FIGS. 6 and 7). For this reason, the wall 31 a is provided with an opening on the second storage chamber 22 side in the first storage chamber 21.

  The accommodation groove 31 is provided with openings 31b and 31c in two of the six wall surfaces (FIGS. 6 and 7).

  In the housing groove 31, a portion facing the wall surface 31a in the connector insertion / extraction direction is an opening 31b. The opening 31 b of each housing groove 31 is closed by the wall surface of the shell 60 assembled to the housing 30.

The opening 31 c is a wall surface of the housing groove 31 on the side of the wire outlet 25 of the shell 60, and is provided on the wiring path of the electric wire 70. That is, the opening 31 c is provided to guide the electric wire 70 in the second storage chamber 22 to the electric wire outlet 25. The opening 31c may have a size that allows only the electric wire 70 to pass therethrough. For this reason, here, the opening 31 c is closed while leaving the opening 31 c ₁ (FIG. 7) having a size and shape corresponding to the diameter of the electric wire 70. The wire lead-out port 25 side of the circular opening 31c ₁ that is the left is provided with a wire draw-out portion 26.

As the wire lead-out portion 26, a space formed when the housing 30 and the rear holder 40 are assembled to each other is used. For example, the housing 30 has a semi-arc-shaped wall surface (hereinafter referred to as a “first semi-arc-shaped wall surface”) 32 communicating with the second storage chamber 22 for each terminal 10 (FIGS. 4 and 7). Further, the rear holder 40 has a semi-arc-shaped wall surface 41 (hereinafter referred to as “second semi-arc-shaped wall surface”) 41 communicating with the second storage chamber 22 by being assembled to the housing 30 for each terminal 10 (FIG. 3). And FIG. 7). When the housing 30 and the rear holder 40 are assembled to each other, the first semi-arc-shaped wall surface 32 and the second semi-arc-shaped wall surface 41 become one wall surface that is connected around the circumference in the circumferential direction. A columnar space is formed. The columnar space communicates with the second accommodation chamber 22 (accommodation groove 31), and is arranged such that the column axis direction is along the wiring path of the electric wire 70. Here, this columnar space is used as the electric wire outlet 26. In this illustration, that the peripheral edges of the first half arcuate wall surface 32, respectively the second accommodating chamber 22 side of the second half-arc-shaped wall 41 is continuous, an opening 31c ₁ is formed. That is, its opening 31c _1, is that the opening of the second accommodation chamber 22 side of the wire draw-out portion 26. Therefore, in this example, the first semi-arc-shaped wall surface 32 and the second semi-arc-shaped wall surface 41 are formed as semi-arc-shaped wall surfaces, and the first semi-arc-shaped wall surface 32 and the second semi-arc-shaped wall surface 41 are formed. The electric wire lead-out portion 26 is a columnar space. Wires 70 of the second housing chamber 22 is inserted into the wire lead-out portion 26 through the opening 31c _1, drawn from the opening of the opposite side of the wire draw-out portion 26 and the opening 31c _1.

  In the illustrated case 20, the shell 60 is assembled to the housing 30 so as to cover the rear holder 40. The shell 60 has a cylindrical portion 61 that covers the electric wire 70 drawn from the opening of each electric wire outlet portion 26 (FIGS. 3 and 4). In the cylindrical portion 61, one opening is used as the electric wire outlet 25, and the three electric wires 70 are drawn outward from the electric wire outlet 25. Note that the outer peripheral surface of the cylindrical portion 61 is covered with a cylindrical braid 79. The braid 79 enhances the shielding performance by accommodating the three electric wires 70 drawn outward, and is tightened with a fastening member 69 such as a fastening band on the outer peripheral surface of the cylindrical portion 61. It has been.

  In the casing 20 configured as described above, each second storage chamber 22 is protected in order to prevent liquid (water, etc.) from entering the connection portion between the wire connection portion 12 and the wire 70 of the terminal 10. A liquid member 80 is provided (FIGS. 6 and 7). Here, a material formed by filling the second storage chamber 22 with a liquid filler (liquid silicon or the like) is used as the liquid-proof member 80. For example, in this connector 1, the connection body of the terminal 10 and the electric wire 70 is assembled to the housing 30, and the rear holder 40 is further assembled to the housing 30 to form the accommodating groove 31, and the electric wire connecting portion 12 and the electric wire 70 are formed in the accommodating groove 31. Place the connection part with. The liquid filler is filled in the housing groove 31 in this state so that the connection portion is covered. Thereby, in the accommodation groove | channel 31, the liquid-proof member 80 is formed with the filler so that the connection part may be included. The filler is solidified in the second storage chamber 22 and formed as a rectangular liquid-proof member 80. In the connector 1, the shell 60 is assembled to the housing 30 after the liquid filler is filled or after the filler is solidified.

  By the way, depending on the nature of the filler, it takes time to solidify. And in this example case 20, since one electric wire lead-out part 26 is formed by combining the 1st semi-arc shape wall surface 32 of housing 30, and the 2nd semi-arc shape wall surface 41 of rear holder 40, the 1st Considering the design tolerance of the semi-arc-shaped wall surface 32 and the second semi-arc-shaped wall surface 41, the assembly tolerance between the housing 30 and the rear holder 40, etc., between the outer peripheral surface of the electric wire 70 and the inner peripheral surface of the electric wire outlet portion 26 A gap is provided in the space. Therefore, in the accommodation groove 31, the liquid filler may flow out from the gap. The outflow amount varies depending on the size of the gap and the viscosity of the filler.

  Therefore, the connector 1 is provided with a liquid stop member 90 for stopping the flow of the filler in order to suppress the outflow of the liquid filler filled in the receiving groove 31 from the electric wire outlet portion 26 (FIGS. 3 and 4). 6 and 7). The liquid stop member 90 is formed in an annular shape, and the electric wire 70 is inserted through the inside thereof. The housing 20 is provided with a third storage chamber 23 into which the outer peripheral surface of the liquid stop member 90 is fitted.

  The third storage chamber 23 is provided in the electric wire outlet 26. A semi-annular recess (hereinafter referred to as “first semi-annular recess”) 33 is formed in the first semi-arc-shaped wall surface 32 along the circumferential direction (FIGS. 4 and 7). In addition, a semi-annular recess (hereinafter referred to as “second semi-annular recess”) 42 is formed in the second semi-arc-shaped wall surface 41 along the circumferential direction (FIGS. 3 and 7). The first semi-annular recess 33 and the second semi-annular recess 42 are formed so that the recesses extend in the circumferential direction when the housing 30 and the rear holder 40 are assembled to each other (that is, when the wire lead-out portion 26 is formed). It becomes an annular recess (hereinafter referred to as “annular recess”) connected around the circumference. In the housing 20, the annular recess is used as the third storage chamber 23.

  When the liquid stop member 90 is fitted into the third storage chamber 23, the fitted outer peripheral surface 90a is brought into close contact with the inner peripheral surface of the third storage chamber 23 over the entire circumference, and the inner peripheral surface 90b. Is closely attached to the outer peripheral surface of the electric wire 70 over the entire circumference (FIG. 7). The liquid stop member 90 has an annular resin body 91 and an annular elastic body 92 arranged concentrically (FIG. 8). In the liquid stop member 90, an elastic body 92 is disposed in an inner space of the resin body 91. Here, the outer peripheral surface of the resin body 91 is the outer peripheral surface 90 a of the liquid stop member 90, and the inner peripheral surface of the elastic body 92 is the inner peripheral surface 90 b of the liquid stop member 90.

  The resin body 91 is formed of, for example, a hard polymer material such as a synthetic resin material. The elastic body 92 is formed of, for example, a polymer material having elasticity such as rubber. In the liquid stop member 90, for example, the resin body 91 is formed of a polymer material harder than the elastic body 92, and deformation of the elastic body 92 in the radial direction (that is, deformation of the outer peripheral surface) is the resin body. It is made to be suppressed by the inner peripheral surface of 91. For this reason, this liquid stop member 90 adheres the inner peripheral surface of the resin body 91 and the outer peripheral surface of the elastic body 92 over the entire circumference. Therefore, the liquid stop member 90 is an integrally molded product of the resin body 91 and the elastic body 92 using an integral molding technique such as two-color molding.

  The resin body 91 is formed so that its outer peripheral surface is fitted to the inner peripheral surface of the third storage chamber 23, so that the outer peripheral surface is in close contact with the inner peripheral surface of the third storage chamber 23 over the entire circumference. Let For this reason, since the liquid stopping member 90 is easy to keep the outer peripheral surface 90a in close contact with the inner peripheral surface of the third storage chamber 23 over the entire periphery, from between the inner peripheral surface of the third storage chamber 23. The outflow of the filler can be suppressed.

  The elastic body 92 is formed so that its inner peripheral surface is in close contact with the outer peripheral surface of the electric wire 70. Since the elastic body 92 is restrained from being deformed outward in the radial direction by the resin body 91 as described above, the force applied from the outer peripheral surface of the electric wire 70 to the inner peripheral surface is difficult to escape. Yes. For this reason, since the inner peripheral surface 90b of the liquid-stopping member 90 is easily kept in close contact with the outer peripheral surface of the electric wire 70 over the entire periphery, the outflow of the filler from the outer peripheral surface of the electric wire 70 is prevented. Can be suppressed.

  For example, since the electric wire 70 has a larger tolerance variation than a resin molded product or the like, the outer peripheral surface shape tends to vary. In addition, the electric wire 70 has flexibility and is arranged in a state where it is bent somewhat with respect to its own axis. In this liquid stop member 90, the elastic body 92 can easily follow such a change in the shape of the electric wire 70 as compared with a liquid stop member formed only of a resin body or a liquid stop member formed only of an elastic body. For this reason, the connector 1 has a high effect of suppressing the outflow of the filler from between the inner peripheral surface 90 b of the liquid stopping member 90 and the outer peripheral surface of the electric wire 70. Thus, since the connector 1 of this embodiment uses the liquid stop member 90 which consists of such a resin body 91 and the elastic body 92, it is a liquid filler in the 2nd storage chamber 22 (accommodating groove 31). Can be prevented from flowing out from the electric wire outlet portion 26, and the outflow of the liquid filler from the electric wire outlet 25 to the outside can be suppressed.

  Further, the liquid stop member made of only the elastic body is less likely to be housed in the third storage chamber 23 than the liquid stop member made of only the resin body. However, since the liquid stopping member 90 of the present embodiment is provided with the resin body 91 on the outer side in the radial direction, the storing operation in the third storage chamber 23 is easy to perform. On the other hand, the liquid-stopping member made only of the resin body makes it difficult to insert the electric wire 70 when the degree of close contact between the inner peripheral surface and the outer peripheral surface of the electric wire 70 is increased. Further, the durability of the coating 72 of the electric wire 70 may be reduced. For this reason, when using the liquid-stopping member which consists only of a resin body, the contact | adherence degree between the outer peripheral surfaces of the electric wire 70 must be reduced, and there exists a possibility of producing a clearance gap between them. However, since the liquid stop member 90 of this embodiment is provided with the elastic body 92 on the inner side in the radial direction, the workability of inserting the electric wire 70 is good, and an unnecessary load is applied to the covering 72 of the electric wire 70 during the insertion operation. The possibility of hanging is low. Therefore, the connector 1 of this embodiment can suppress the outflow of the liquid filler to the outside while ensuring good assembly workability and durability.
