Description

The The present invention relates to a connector, which with an electrical and / or electronic part, such as a relay, a fuse, a resistor, a processor or the like. Is connectable.

A relay mounting portion having a relay mounting structure disclosed in Japanese Unexamined Patent Publication No. 9-35605 is known as the one corresponding to this type of connector. Like this in 14 and 15 is shown is a relay mounting portion 1 such that a relay 5 between a pair of outer walls 2 is fittable, and two pairs of resilient locking pieces 3 from a bottom wall 4 inside the outer walls 2 Stand up or stand up while away from the outer walls 2 are spaced. A locking claw 7 , which with a locking or locking projection 6 is engageable, which at the relay 5 is provided at the front end of each resilient locking piece 3 educated. The resilient locking pieces 3 are resilient to the outside in the process of inserting the relay 5 in the relay mounting section 1 deformed and resiliently return to the locking jaws 7 with the locking tab 6 when moving over the locking tab 6 to engage. In this way, the relay becomes 5 at a detachment from the relay mounting portion 1 prevented. In addition, the outer walls prevent it 2 the excessive resilient deformation of resilient locking pieces 3 in that they are arranged at such positions to abut against the resilient locking pieces 3 to be brought when the resilient locking pieces 3 resilient to be deformed outwards.

Because the outer walls 2 separated from the resilient locking pieces 3 outside the resilient locking pieces 3 are provided while removing from the resilient locking pieces 3 in the relay mounting section 1 According to the connector according to the prior art, the relay mounting portion tends 1 to become tall overall. Although such a problem by omitting the outer walls 2 can be solved, it is not reasonable as a function of preventing the excessive resilient deformation of the resilient locking pieces 3 get lost.

Furthermore a connector of this type usually consisted of a receptacle, in which a relay through an opening fittable which is formed in the front surface thereof, and one receiving a connection Section or terminal receiving section, which continuously or subsequently backwards from the rear surface of the A receptacle for receiving Anschlußpaßstücken extends, and resilient interlocking or locking pieces, which in each case a locking or locking claw on its front Have end, are resilient deformable provided on a surrounding wall of the recording. Window holes leading to the Gripping the relay are in the surrounding wall the recording formed by cutting. When the relay goes through the opening fit the recording it is inserted while it resiliently recovers the resilient locking pieces Outside deformed. When the relay is in a proper position, return the resilient locking pieces resilient to theirs original or starting positions back, around the locking claws with the rear end surface of the Engage relay with respect to its insertion direction, As a result, the Relay is locked so as not to exit or fall out. Such a connector for For example, a relay is disclosed in Japanese Unexamined Patent Publication No. 9-35605.

In in the case of the connector according to the state The technology is or will be at a release or removal of the relay for one Maintenance or for some other reason the locking claws Finger held to be resilient to the resilient locking pieces outward to deform, and a rear part The relay is held by other fingers while maintaining the above state is obtained. Thereafter, the relay is pulled out of the receptacle and away. Since the relay must be pulled with a fairly large force to the relay connections and to disconnect the terminal fittings, however, the process is sometimes difficult. There was therefore one Demand for an improvement in handleability or operability. It was also difficult, precise to judge if the relay is in a proper position connected in the recording or connected or not.

US-A-6 126 474 discloses a connector having a receptacle, in which an electrical part can be used. Furthermore This connector includes a resilient locking piece which is engageable with the electrical part, and a one Deformation preventing section to prevent excessive deformation of the resilient locking piece to prevent.

US-A-5 980,297 discloses a connector having a locking piece and a locking piece a deformation preventing portion integrally molded with the connector housing or cast.

JP-10 050 404 discloses a connector for a PC card, wherein the Connector includes a hole in which a removal tool is used to pull a Card at the time of an inspection.

following become preferred embodiments of the present invention with reference to the enclosed Drawings described.

<First Embodiment>

A first embodiment in which the present invention is applied to a connector for a relay (as a preferable electric and / or electronic element) for use in a vehicle will be described with reference to FIG 1 to 13 described. By 10 a connector is identified. This connector 10 consists of a terminal receiving portion or terminal receiving portion 12 for receiving one or more female or female terminal fittings 11 (please refer 12 , not illustrated in other figures) and a picture 20 which is in front of or adjacent to the terminal receiving portion 12 is provided and is provided and is substantially in the form of a rectangular or rectangular pipe which opens to the front.

One or more cavities 13 is formed around the terminal receiving portion 12 penetrate substantially along a longitudinal direction, and the female terminal fittings 11 are at least partially usable in it. The cavities 13 of this embodiment are at one or more level (s) or level (s), preferably at three upper, middle and lower levels in 2 arranged. There is a total of, for example, five cavities 13 one at each of the upper and middle stages, and three are arranged transversely substantially adjacent to each other at the lower stage. A resiliently deformable locking portion 14 is preferably in each cavity 13 formed and with the female terminal fitting 11 engageable to lock it.

The recording 20 is formed to have such a shape and size that a relay 50 (as a preferred electrical / electronic element) at least partially insertable therein through an insertion opening formed in the front surface of the receptacle 20 is trained. The relay 50 , which at least partially in this recording 20 can be mounted or mounted, is substantially in the form of a rectangular or rectangular parallelepiped in total and one or more relay terminal (sockets) 51 protrude on the ground surface thereof at positions substantially corresponding to the female terminal fittings 11 which is in the cavities 13 are used.

Each of opposite walls 21 , which at the top and bottom of the recording 20 in 2 are cut in a U-shape at its front end to a recess or a groove or groove 22 train. As will be described in more detail next, each well is 22 with leading edges or edge or edge sections 23 (a pair of left and right or lateral guide edges) 23 in 3 ) for guiding the insertion of a detecting tool or actuator 60 for checking an electrical connection, and stop edges 24 , with which an engaging projection or extension 63 the detecting actuator 60 essentially comes into contact with the detecting actuator 60 to stop are at an end position of each leading edge 23 provided or made available.

Here is the construction of the detecting actuator 60 briefly described. As in 10 and 11 shown, there is the detecting actuator 60 from an actuatable section 61 , preferably substantially in the shape of a rectangular parallelepiped, and a main body 62 facing forward (or to the connector 10 ) from the front surface of the actuatable section 61 extends. The main body 62 has the outer surfaces of its rear portion, preferably its rear half shaped such that the rear portion, preferably the rear half at least partially into the receptacle 20 is conformable with the outer surfaces thereof substantially in direct contact with the inner surfaces of the receptacle 20 are held or are. The engaging projection 63 which is substantially in sliding contact with the corresponding recess 22 the recording 20 can be brought protrudes from each of the left and right or lateral side surfaces of the rear portion / the rear half. One or more detecting pin (s) 64 which (r) with the corresponding locking sections 14 in the cavities 13 are projecting from the front surface of the main body 62 before, and one or more, electrically conductive, connection detecting pin (s) 66 which are shorter than the detecting pins 64 is and in contact with the female terminal fittings 11 can be brought up, protrude (protrude) near the corresponding detecting pins 64 in front. Each detecting pin or pin 64 is with a flat section 65 provided at the front end, which at least is partially insertable into an insertion space Q, which between the locking portion 14 and the inner surface of the cavity 13 is defined when the locking section 14 with the female terminal fitting 11 is engaged at a proper insertion position (see 13 ).

Next, the functions of the detecting actuator 60 described. First, as in 12 shown, the actuatable section 61 gripped or manipulated, or may be grasped or manipulated to at least partially detect the detecting actuator 60 in the recording 20 Insert through the insertion and it to the back of the recording 20 to press while the engaging projections or elevations 63 essentially in sliding contact with the leading edges 23 being held. As in 13 shown, when the flat sections 65 at the front end of the detecting pins 64 Where they are at least partially inserted into the insertion spaces Q, the front end surfaces of the engaging projections reach 63 essentially in contact with the stopping edges or edges 24 the wells 22 and the connection detecting pin (s) 66 essentially comes into abutment against the forward ends of the female terminal fitting (s) 11 whereby he or she is electrically connected to the female terminal fitting (s) 11 is connectable or are.

In contrast, when the female terminal fitting 11 is insufficiently used without the locking portion 14 to engage, the flat section 65 the leading end of the detecting pen 64 the front end surface thereof is substantially in abutment against the locking portion 14 , whereby any further insertion of the detecting actuating element 60 is prevented or prevented. Thus, the front end surfaces of the engaging projections come 63 not in contact with the stopping edges or edges 24 the wells 22 , Still the connection detecting pin (s) is still 66 electrically with the female terminal fitting (s) 11 connectable to the front end (s) of the female terminal fitting (s) 11 to reach. In this way, whether the female terminal fittings 11 are properly inserted or not, by checking an electrical connection by means of the connection detecting pin (s) 66 be detected. Such detection can also be performed by the contact state of the engaging projections 63 with the stopping edges or edges 24 viewed from the outside.

Each of opposite walls 25 the recording 20 which are at positions different from the opposite walls 22 (and left and right in 2 ) is arranged with a pair of slots 26 formed extending rearwardly from the front end thereof. A resilient locking piece 27 which is integral or integral with the receptacle 20 is formed and with the relay 50 is engageable to the solution or removal of the relay 50 from the recording 20 to prevent is between each pair of slots 26 provided or made available. Each resettable locking piece 27 includes a main body 27F and a locking claw 27A connected to the rear end surface or a rear stepped surface of the relay 50 (as in a direction of insertion of the relay 50 in the recording 20 seen) is engageable when the relay 50 is arranged at a proper or appropriate position (when the relay 50 to a substantially proper depth in the receptacle 20 is received) protrudes inwardly from the front end of the main body 27F in front. An inclined or bevelled surface 27B for guiding the relay 50 and / or the resilient deformation of the resilient locking piece 27 is on the upper surface of each locking claw 27A intended.

An inner projection 27E bulges outward in a width direction WD (or in a direction substantially in the plane of the resilient locking piece 27 or the wall lies in which the resilient locking piece 27 is provided) on the inside of each main body 27F , This inner projection 27E has an extended locking surface 27H (please refer 6 ) substantially flush with a. locking surface of the locking claw 27A which at least partially with the relay 50 is engageable, whereby an area of engagement of the locking claw 27A with the relay 50 is enlarged by a shaded or hatched portion, as in 7 is shown. The inner projections or extensions 27E are usually inside the slots 26 (upper slots in 2 ) arranged. When the resilient locking pieces 27 resiliently deformed outward, pass the inner projections 27E first the slots 26 and get into abutment against the inner surfaces of the receptacle 20 if the resilient locking pieces 27 be resiliently deformed further. The recording 20 , against which the inner projections or elevations 27E can form an excessive deformation preventing sections 40 , and areas of recording 20 along the slots 26 (upper slots in 2 ) are extended to the outside and ge bulges to substantially the outer sides of the slots 26 and / or the inner projections 27E cover. The excessive deformation preventing portions 40 these embodiments are preferably over the substantially entire length of the slots 26 provided and cover only the outer sides of the slots 26 without the outer sides of the main body 27F cover. Any section preventing excessive deformation 40 is with a sloped or bevelled surface 40A for a discharge or exit of the corresponding inner projection 27E trained to the relay 50 to be removed (see 8th ).

In addition, an outer protrusion bulges 27G outwardly in a width direction WD (or in a direction substantially in the plane of the resilient locking piece 27 or the wall lies in which the resilient locking piece 27 is provided) on the outer side of each main body 27F , These outer projections or elevations 27G are preferably substantially in the form of a rectangular flat plate and integrally overlap integrally (at least partially) the front ends of the resilient locking pieces 27 from the outside (see 1 ), and at least partially cover the outer sides of the slots 26 (lower slots in 2 ). The outer projections 27G essentially come into abutment against the outer surfaces of the recording 20 which act as an excessive deformation preventing sections 41 Serve when the resilient locking pieces 27 resilient are deformed inward or become. The outer surfaces of the recording 20 as the excessive deformation preventing portions 41 are recessed at positions where the outer projections 27 essentially come into contact, creating depressions or recesses 29 be formed. The wells 29 are formed to form pins or pins for forming the outer projections 27G and are useful in improving the strength of the molding pins.

Next, the functions of this embodiment will be described. First, the relay 50 at least partially through the insertion opening of the receptacle 20 used. In the insertion process of the relay 50 Will the one or more resilient locking pieces be or become 27 in substantially sliding contact with the outer surfaces of the relay 50 while being resiliently deformed outward (see 4 and 5 ). When the relay connections 51 reach substantially proper connection positions where they can be connected to the female terminal fitting (s) 11 in the recording 20 become the resilient locking pieces 27 resiliently returned to the locking claws 27 with the rear end surface or a rear side of a stepped portion of the relay 50 how to engage hooks (see 6 ).

The relay 50 will be out of the recording 20 removed or removed by the locking claws 27A is disengaged and from the recording 20 is pulled. Specific are or will be, as in 8th shown is the locking claws 27A For example, held by fingers and further from each other in directions of arrows S pressed to the relay 50 in a removal direction Z to free or release. At this time, the resilient locking pieces 27 resiliently deformed beyond its elastic limit, since the operation is performed particularly by a feeling of an operator. In this embodiment, however, the inner projections 27E essentially in abutment against the inner surfaces (bevelled surfaces 40A ) of the excessive deformation preventing portions 40 (Admission 20 ), whereby any further displacement of the resilient locking pieces 27 is prevented or prevented. Thus, the excessive outward resilient deformation of the resilient locking pieces 27 safely prevented.

In the event that the resilient locking pieces 27 resiliently deformed inward, the outer projections can 27G essentially in abutment against the outer surfaces of the receptacle 20 as the excessive deformation preventing portions 41 resulting in any further displacement of the resilient locking pieces 27 is hampered. Such can also be the excessive, inwardly directed, resilient deformation of the resilient locking pieces 27 be safely prevented.

Although the outer walls 2 on the outer sides of the resilient locking pieces 3 are provided while they are in the relay mounting section 1 according to the prior art are spaced (see 15 ), are the resilient locking pieces 27 and the excessive deformation preventing portions 40 . 41 integral or integral with or on admission 20 formed in this embodiment. In this way, the enlargement of the connector as a whole can be avoided in contrast to the prior art.

Because the inner projections 27E preferably the extended locking surfaces 27H substantially flush with the locking surface of the locking claws 27A , the areas of engagement of the locking jaws may be 27A with the relay 50 by the width of the extended locking surfaces 27H be increased, which results in that the relay 50 safe and strong can be locked. In addition, unlike the relay mounting section 1 According to the prior art, the outer surfaces of the resilient locking pieces 27 not completely through the excessive deformation preventing sections 40 covered. Thus, a degree of resilient deformation of each resilient locking piece can 27 be seen from the outside. In other words, if for the resilient locking pieces 27 are not seen to be resiliently deformed, the properly mounted state of the relay 50 be judged in an advantageous manner. In contrast, when of the resilient locking pieces 27 is seen to be resiliently deformed, the relay 50 be judged advantageously as partially mounted without the locking claws 27A precisely engaged with the relay 50 are.

Accordingly, in order to provide a connector having improved operability which can avoid becoming larger in total while preventing the excessive resilient deformation of resilient locking pieces, a connector is provided 10 with a recording 20 provided, in which a relay 50 or another electrical / electronic part or element, such as a fuse, resistor, etc., is at least partially insertable through an insertion opening formed in the front surface of the receptacle 20 is trained. At least one resilient locking piece 27 which with the relay 50 is engageable to the removal or release of the relay 50 To prevent it is between a pair of slits or depressions 26 provided, which in the recording 20 are formed to substantially backward from the front end thereof or substantially along the insertion direction of the relay 50 to extend. In addition, the recording 20 with an excessive deformation preventing section 40 which essentially abuts against the resilient locking piece 27 can be brought to the excessive resilient deformation of the resilient locking piece 27 to prevent if the resettable locking piece 27 resiliently deformed is or will.

The side walls 123A the recording 123 which with the window holes 123B are formed are substantially subsequent to or continuously with the front ends of the side walls of the one terminal receiving portion 122 over graduated sections 123J , The inner surfaces of the stepped sections 123J are preferably substantially flush with and subsequent to the front surface of the one terminal receiving portion 122 and act as contact surfaces 123Q with which the relay 110 , which in an insertion direction ID in the recording 123 is used, essentially comes in contact. The relay 10 is fitted until it is in contact with the contact surfaces 23Q arrives.

At a position of one or more, preferably each side wall 123A near or adjacent the terminal receiving portion 122A , is a hole 123K designed to preferably also a part of the existing there, corresponding stepped portion 123J to cut or traverse. The front surface and / or an edge portion of the one terminal receiving portion 122 and that of the relay used 110 (or an edge portion between the electrical / electronic part 110 and a bottom surface of the receptacle 123 and / or a front portion of the one terminal receiving portion 122 ) can at least partially through the holes 123K be seen. Like this in 19 shown is the hole 123K also in a side wall 123C the recording 123 Trained where the rear locking interlocking piece 123D provided or made available.

A pedestal or projection or extension 123M which bulges outward and as a supporting point of a releasing tool or actuator 170 which is operated to the relay 110 To solve or remove is at a part of each stepped section 123J formed, which at least partially in the hole 123K is arranged. The base 123M is preferably substantially in the shape of a column as a whole and from the other part of the stepped portion 123J spaced apart, and this clearance is substantially in communication with the hole 123K , In addition, the height of the pedestal 123M deeper than that of the other part of the stepped section 123J set, and the front end thereof with respect to a height direction has its front Section cut obliquely to a beveled or guiding surface 123N train.

The relay 110 is at least partially in the insertion direction ID in the recording 123 of the connector 120 from a matching side (left side in 20 ) used. The edges of the front surface of the relay 110 essentially come in contact with the leading or guiding surfaces 123D the locking claws 123F the resilient locking pieces 123D and push or push them, causing the relay 110 is pushed while resilient the resilient locking pieces 123D deformed or deformed outwards.

If the relay 110 in the insertion direction ID is pressed to a position where it is substantially in abutment against the front surface of the terminal receiving portion 122 and the inner surfaces of the stepped portions 123J are moved, that is pushed to a proper or corresponding connection position, are or are the resilient locking pieces 123D at least partially reset or returned to the locking claws 123F with the rear surface (or with the rear portion of a stepped portion) of the relay 110 with respect to its insertion direction to engage the relay 110 to lock. During this time, the one or more relay terminals (terminals) 111 at least partially into the corresponding cavities 140 to be connected to the respective female terminal fittings received therein.

In this case, the contact of the front surface of the relay 110 and that of the one terminal receiving portion 122 through the holes 123K can be seen, whereby an assessment can be made whether the relay 110 properly in the recording 123 connected or not connected. In this way it can be prevented that the relay 110 stops or remains at a depth of incomplete connection.

In addition, in the case of releasing the relay 110 from the recording 123 for serviceable or otherwise, the resilient locking pieces 123D first resiliently deformed outwards to the locking claws 123F from the relay 10 except to intervene. In this state, the front end of the releasing actuator 170 (For example, a flat screwdriver) for the relay 110 at least partially into the hole 123K used or can be used in it while passing along the leading surface 123N of the pedestal 123M slides and pushes itself between the front surface of the relay 110 and that of the one terminal receiving portion 122 , The following will, as in 21 shown the actuator 170 forcibly with the pedestal 123M displaced or displaced or pivoted as a supporting fulcrum, whereby the relay 110 from the front surface of the one terminal receiving portion 122 or raised in a withdrawal direction. Then the relay will 110 taken or can be taken and pulled out, for example by fingers. As a result, the relay becomes 110 from the recording 123 solved or removed or can be solved. Here can if the relay 110 for example, gripped by fingers and pulled out without the actuator 170 to use the relay 110 can not be solved unless a strong traction is exercised. If the holes 123K As described above, the actuating element 170 at least partially through the hole 123K be used, making this easier, the relay 110 using the actuator 170 to solve.

As the pedestal 123M as a supporting fulcrum or for the pivotal movement of the actuator 170 is used when the actuator 170 is actuated, the dissolution process can proceed with good handleability. In addition, since the relay 110 can be solved or removed with a small force due to a leverage, working stresses can be reduced. In addition, the actuator can 170 smooth or even between the front surface of the relay 110 and that of the one terminal receiving portion 122 push by the front end of the actuator 170 is caused along the leading surface 123N of the pedestal 123M to glide.

In addition, the actuator can 170 be pressed and the connection position of the relay 110 can visually from three sides of the connector 120 ie from many angles by forming the holes 123K in two or more, for example three of the side walls 123A . 123C the recording 123 beeing confirmed. In this way, the connector 120 be used in a wider area of an application.

<Third Embodiment>
