    [0001] The invention relates to an electrical connector to be used for an electrical connection between devices mounted in an automobile or different industrial machines, and more particularly to an electrical connector comprising a locking arm provided in an electrical connector for connecting the electrical connector. to another electrical connector. Japanese Patent Application Publication No. 2005-135751 discloses an electrical connector comprising a lock arm, a release unit formed at a rear end of the lock arm, and a flexible support portion formed between the lock arm blocking and an upper surface of a female housing to extend in a forward-to-back direction. In the electrical connector, the locking arm is connected to the support portion at a location closer to a front end than a rear end of the support portion, thereby ensuring that the locking arm and the support portion can be arranged in a small space above an upper surface of the female housing as compared to an electrical connector having a locking arm connected to a support portion at a location closer to a rear end than a front end of the support part, and the female connector can thus be miniaturized. Japanese Patent Application Publication No. 2013-30323 discloses an electrical connector comprising a locking arm, an engaging hook to be brought into engagement with an engagement hole formed at a connector housing when the electrical connector is inserted into the connector housing, and a locking release unit for releasing the engagement hook from the engagement hole when the locking arm is pushed back from the connector housing beyond the hook of engagement, a fulcrum located closer to a rear end being positioned closer to the engagement hook than a fulcrum located closer to a front end in a direction opposite to a direction in which the engagement hook extends. Fig. 13 illustrates an example of an inner housing of a conventional electrical connector including a locking arm, and Fig. 14 illustrates an example of an outer housing in which the inner housing is inserted. As shown in Fig. 13, a lock arm 51 is formed over an upper surface of an inner housing 50. As shown in Fig. 14, an outer housing 40 includes a hood 41 having a rectangular cross section, in which the inner housing 50 is inserted. The cover 41 comprises on an inner surface of a top wall a recess 42 in which the locking arm 51 of the inner housing 50 is inserted. A plurality of metal terminals 43 (see Fig. 16) extend into the cover 41 in a direction in which the inner housing 50 is inserted into the outer housing 40.
    [0002] The lock arm 51 of the inner housing 50 comprises a lock arm body 52, a front arm 53 supporting a front end of the lock arm body 52 on an upper surface of the inner housing 50, a rear arm 54 supporting a rear end the lock arm body 52 on the upper surface of the inner housing 50, a locking projection 55 to be locked with a locking unit (not shown) located in the recess 42 formed at the cover 41 of the outer housing 40, and a release unit 56 for releasing the locking projection 55 from the blocking unit. As illustrated in FIG. 14, an electrical connector comprising the cover 41 having a relatively large width of an opening is accompanied by a problem that, if the locking projection 55 has a relatively small width, the inner housing 50 is easily inclined relative to the outer casing 40 when cables connected to the metal terminals inserted into the inner casing 50 are pulled. Thus, the lock projection 55 may be designed to have a relatively large width to avoid the problem. As shown in Fig. 15, the lock projection 55 designed to have a width WB greater than a first width WA transfers outwardly a point at which the inner housing 50 begins to tilt with the result that that the inclination of the inner housing 50 is made smaller. However, the blocking protrusion 55 having the larger width WB poses a problem in that, if the inner case 50 is inserted into an inclined condition in the outer case 40, as illustrated in FIG. 16, the inner case 50 It can be inserted deep into the outer housing 40, with the result that the inner housing 50 comes into contact with the metal terminals 43 extending into the inner housing 40 thereby causing the metal terminals 43 to be bent and / or damaged.
    [0003] Due to the above mentioned problem in the conventional electrical connector, it is an object of the present invention to provide an electrical connector capable of preventing an inner housing from being inserted deeply into a slanted condition in an outer housing when the inner case is inserted into the outer case. In one aspect of the present invention, there is provided an electrical connector comprising a first housing in which an interior space is formed, and a second connector comprising a second housing insertable into the interior space, the first housing comprising in the space a locking engagement portion, the second housing comprising a locking arm having a locking projection to be engaged with the locking engagement portion, the first housing comprising in the interior space at least one rib extending in a first direction in which the second housing is inserted into the interior space, the locking arm being formed with a guide space in which the rib can be inserted when the second housing is inserted into the interior space . Since the electrical connector according to the present invention comprises a rib extending in the first direction mentioned above, it is possible to prevent the second housing from being inserted deeply into an inclined condition in the first housing when the second housing is inserted into the first housing. The locking arm of the second housing is formed with a guide gap extending in the first direction mentioned above to allow the rib of the first housing to enter, and therefore the rib of the first housing does not interfere. not with the second housing when the second housing is inserted into the first housing, which ensures that the second housing can be inserted into a correct posture in the first housing. It is preferable that the guide space has a shorter length than a total length of the locking arm, the locking arm being divided by the guide space. It is preferable that the guide space is defined as a groove formed at the level of the locking arm. It is preferable that the first housing is formed with a recess in which the locking arm is inserted, the rib being formed in the recess. It is preferred that the rib is formed on at least a portion of a total length of the interior space in a direction along the length of the first housing. It is preferred that the electrical connector further comprises at least one second rib formed on a bottom of the first housing, the second rib extending in the first direction, the second housing being formed with a recess in which the second rib is inserted. . It is preferred that the second rib is formed at a center in a widthwise direction of the first housing. It is preferred that the second rib is formed over at least a portion of a total length of the interior space in a direction along the length of the first housing. For example, the lock arm may comprise a lock arm body extending in the first direction, the lock arm body being resiliently deformable in a second direction perpendicular to the first direction, a first leg connecting the locking arm body at one end to the second housing such that a gap is formed between the lock arm body and a surface of the second housing, a second leg connecting the lock arm body to the other end to the second housing such that a gap is formed between the lock arm body and the surface of the second housing, and a wall extending obliquely from the lock arm body in a direction away from the surface of the second housing, where, when the wall is pushed towards the locking arm body, the locking arm body is deformed, the first and second branches acting as seals, then, the wall comes into contact at a distal end with the locking arm body, and then the locking arm body is deformed, the first and second branches acting as dots and a stop point acting further as a working point to thereby allow the locking projection to be released from the locking engagement portion of the first housing, the stop point being defined as a point at the the level of which the wall and the blocking arm body come into contact with each other. The wall is located at the rear of the locking arm locking projection supported at the first and second branches on a surface of the second housing facing the locking engagement portion of the first housing, and extends into oblique from the blocking arm body to the second branch. When the wall is pushed toward the lock arm body, the lock arm body is deformed with the first and second limbs acting as fulcrums, and then the wall comes into contact at a distal end. with the locking arm body, and then the locking arm body is deformed with the first and second branches acting as fulcrums and further with the stop point acting as the working point. Thus, the locking arm locking projection can move further even if the wall is moved a short distance, and therefore the locking projection can be released from the locking engagement portion of the first housing. It is preferable that the second branch comprises third and fourth branches formed at opposite ends in a direction in the width direction of the second leg, and at least a fifth leg formed between the third and fourth legs.
    [0004] When the locking arm is deformed to thereby release the locking protrusion from the locking engagement portion of the first housing, the lock arm body can be prevented from being deformed at a rear end in the center in a direction in the width direction, and the blocking projection can thus be made to move securely over a desired distance. It is preferable that a gap between a distal end of the wall and the lock arm body is smaller than the gap between the lock arm body and the second housing surface. The advantages obtained by the present invention mentioned above will be described below. First, the first housing is formed with a rib extending in a direction in which the second housing is inserted into the first housing, and the locking arm is formed with a guide space in which the rib can be inserted when the second housing is inserted. housing is inserted into the first housing. Therefore, it is possible to prevent the second housing from being inserted into an inclined condition in the first housing, and furthermore, it is also possible to prevent the second housing from contacting and bending the terminals. even if the metal terminals extend into the first housing.
    [0005] Second, the lock arm is adapted to include a lock arm body extending in the first direction, the lock arm body being resiliently deformable in a second direction perpendicular to the first direction, a first leg connecting the lock arm locking arm body at one end to the second housing such that a gap is formed between the lock arm body and a surface of the second housing, a second leg connecting the lock arm body to the other end to the second housing such that a gap is formed between the lock arm body and a surface of the second housing, and a wall extending obliquely from the lock arm body in a direction away from the surface of the second housing, where, when the wall is pushed towards the locking arm body, the locking arm body is deformed with the first and second branches acting nt as the fulcrums, then the wall comes into contact at a distal end with the locking arm body, and then the lock arm body is deformed with the first and second limbs acting as as fulcrum and further with a stop point acting as a working point to thereby allow the locking projection to be released from the locking engagement portion of the first housing, the stop point being defined as a point at which the wall and the locking arm body come into contact with each other. By designing the locking arm to have the aforementioned structure, it is possible to release the locking projection from the blocking engagement portion by causing the wall to move only a short distance, thereby to make an electrical connector with reduced height.
    [0006] Third, the locking arm is supported by the second leg on a surface of the second housing, the surface facing the blocking engagement portion of the first housing, the second leg including the third and fourth branches formed at the ends. opposed in one direction in the direction of the width of the second branch, and at least one fifth branch formed between the third and fourth branches.
    [0007] By designing the second leg to have the above-mentioned structure, it is possible to prevent the locking arm body from being deformed at a rear end in the center in a widthwise direction. , and the blocking arm locking projection can thus be moved to a desired distance. Thus, it is possible to securely release the locking projection from the locking engagement portion by causing the wall to move only a short distance.

    [0016] In Fig. 1, an electrical connector 1 according to the preferred embodiment comprises a male connector 1M and a female connector 1F to be inserted into the male connector 1M.
    [0017] The male connector 1M comprises an outer housing 10 as a male housing, and a plurality of male metal terminals 12. The outer housing 10 comprises a cover 11 having a rectangular section and which is open to the female connector 1F. In the cover 11, the male metal terminals 12 protrude towards the female connector 1F. The cover 11 is formed with a locking engagement portion 13 on an inner surface of an upper wall at one end closer to the female connector 1F. The blocking engagement portion 13 protrudes downwardly in the hood 11 at a center in a widthwise direction (a direction perpendicular to a plane defined by FIG. 1) of the outer casing 10. this is illustrated in FIGS. 2 to 4, a first rib 14 and a second rib 15 are formed in the cap 11. The first rib 14 is formed on an inner surface of an upper wall of the outer casing 10, and extends in a direction 100 (see Figure 1) in which the female connector 1F is mounted in the male connector 1M. The cover 11 comprises, on an inner surface of an upper wall and at a center in a direction in the width direction of the outer casing 10, a recess 16 acting as a guide space having a corresponding shape. to a locking arm mentioned later 21 of an inner housing later mentioned 20 so as to allow the locking arm 21 to be inserted therein. The locking engagement portion 13 and the first rib 14 are formed in the recess 16. The first rib 14 is located at the center of the recess 16 in a direction in the width direction of the outer housing 10. The second rib 15 is formed on a bottom of the cover 11 at a center of the recess 16 in a direction in the width direction of the outer housing 10. That is, the second rib 15 is located just below the first rib 14. The female connector 1F comprises the inner housing 20 (see Figures 5 and 6) having a rectangular cross section, as a female housing, and a plurality of female metal terminals (not shown) housed in the inner housing 20 and to be electrically connected to the male metal terminals 12 of the male connector 1M. The inner case 20 is inserted into the cover 11 of the outer case 10. In the description, the expression "before" refers to a front (on a left side in FIG. 1) in the direction 100, and the expression " rear "refers to a back (on a right side in Figure 1) in the direction 100. As shown in Figures 1 and 5, the inner housing 20 is formed integrally with a locking arm 21 on an upper surface 20a (a surface facing the locking engagement portion 13 of the outer housing 10). As shown in FIG. 7, the locking arm 21 comprises a locking arm body 22 in the form of a plate extending in a direction along the length of the inner housing 20, a front branch 23 supporting a leading edge of the lock arm body 22 on the upper surface 20a of the inner housing 20, a rear leg 24 supporting a rear edge of the lock arm body 22 on the upper surface 20a of the inner housing 20, a locking projection 25 to be locked with the locking engagement portion 13 of the outer casing 10 when the inner casing 20 is inserted into the casing 11, and a locking release unit 26 for releasing the locking projection 25 of the casing part. locking engagement 13 of the outer housing 10. The locking arm body 22, the front arm 23, the rear arm 24, the locking projection 25, and the locking release unit 26 are integrally formed. with the inner housing 20. The lock arm body 22 is supported by the front and rear legs 23 and 24 above the upper surface 20a of the inner housing 20 so that there is a gap G1 between the body of the locking arm 22 and the upper surface 20e of the inner housing 20. The locking projection 25 protrudes upwardly from the locking arm body 22 between the front branch 23 and the locking release unit 26. The locking projection An inclined front surface 25a extending obliquely and rearwardly from an upper surface of the lock arm body 22, and a rear surface 25b standing vertically on the upper surface of the lock arm body 22. Lock release unit 26 is at the rear of blocking projection 25, and extends obliquely in a direction away from inner case 20. More specifically, blocking release unit 26 is extends obliquely to the rear, that is to say to the rear branch 24. The front branch 23 protrudes downwardly from the front edge of the locking arm body 22. The front branch 23 is connected at a lower end at the upper surface 20a of the inner housing 20 at a front end of the inner housing 20. The locking arm body 22 tilts upwardly between the front leg 23 and the locking projection 25, and extends parallel to the upper surface 20a of the inner housing 20 between the lock projection 25 and the rear leg 24. As shown in Fig. 5, the lock arm body 22 and the front leg 23 are formed with a guide space 28 at the a center in a direction in the width direction of the inner housing 20. The guide space 28 guides and allows the first rib 14 to be inserted therein when the inner housing 20 is inserted into the hood 11 of the outer casing 10. The guide space 28 is shaped to receive the first rib 14, and extends from the front of the inner housing 20 beyond the locking projection 25. The locking arm 21 is divided into two parts by the space 28 in an area where the guide space 28 exists. As shown in Figure 5, the inner housing 20 is formed at a lower surface with a guide recess 32 shaped to receive the second rib 15 to allow the second rib 15 to enter when the inner housing 20 is mounted in the cover 11 of the outer housing 10. The rear branch 24 comprises a vertical portion 24a standing vertically at a rear end of the inner housing 20 on the upper surface 20a of the inner housing 20, and an extended portion 24b extending horizontally forward from an upper end of the vertical portion 24a. As illustrated in Fig. 8, the rear leg 24 in the present embodiment comprises a left leg 27a and a straight leg 27b located at opposite ends in a direction in the width direction of the rear leg 24, and a intermediate branch 27c located between the left branch 27a and the right branch 27b. Each of the left branch 27a, the right branch 27b and the intermediate branch consists of the vertical portion 24a and the prolonged 24b mentioned above.
    [0018] The lock arm body 22 is supported at a forward end by the front leg 23 on the inner housing 20, and at a rear end by the vertical portion 24a of the rear leg 24 on the inner housing 20. and is vertically deformable elastically, i.e., in a direction perpendicular to the upper surface 20a of the inner housing 20 with the forward leg 23 and the vertical portion 24a, both of which act as dots. support. Not only the lock arm body 22, but also the extended portion 24b of the rear leg 24 may be deformed elastic. The lock release unit 26 includes walls 28a, 28b and 28c (see Fig. 5) extending obliquely and rearwardly from the upper surface of the lock arm body 22, and a finger contact 29 in the form of a horizontal plate connecting upper ends of the walls 28a, 28b and 28c to each other. The finger contact 29 of the blocking release unit 26 is above the extended portion 24b of the rear leg 24 with a gap G2 therebetween (see Fig. 7). As shown in FIG. 10A, the female connector 1F is inserted into the male connector 1M in the electrical connector 1 having the above-mentioned structure by inserting the inner case 20 into the cover 11 through the back of the outer case 10. As shown in Figs. 11A and 113, even if an attempt is made to insert the inner housing 20 in an inclined condition in the outer housing 10, the 27c is a first rib 14 formed in the housing cover 11 10 prevents the inner housing 20 from being inserted deeply into an inclined condition into the outer housing 10. Thus, it is possible to prevent the inner housing 20 from abutting and bending the male metal terminals 12 housed in the housing outside 10. The second rib 15 acts in the same way as the first rib 14. More specifically, the second rib 15 formed in the hood 11 of the housing The outer casing 10 prevents the inner casing 20 from being inserted deeply into an inclined condition into the outer casing 10, thereby preventing the inner casing 20 from abutting and bending the male metal terminals 12 housed in the outer casing 10. In the case of the inner housing 20 inserted in a correct posture in the outer housing 10, since the first rib 14 and the second rib 15 formed in the outer housing 10 are inserted into the guide space 28 and the guide recess 32, 20 respectively, the first rib 14 and the second rib 15 do not interfere with the inner case 20. Thus, it is ensured that the inner case 20 is inserted into a correct posture in the outer case 10. When the connector 1F female is mounted in the male connector 1M, as shown in Figure 10A, the inner housing 20 is inserted into the cover 11 Through the rear of the outer casing 10. When the locking projection 25 of the inner casing 20 abuts on the locking engagement portion 13 of the outer casing 10 to urge the locking projection 25, the locking arm body 22 is resiliently deformed downwardly at a central portion, as shown in FIG. 1013, and the locking projection 25 of the inner housing 20 is thus lowered beyond the locking engagement portion 13 10. When the locking projection 25 passes beyond the locking engagement portion 13, the locking arm body 22 returns to its original form shown in FIG. 10A, and therefore the the locking projection 25 of the inner housing 20 is engaged or blocked with the locking engagement portion 13 of the outer housing 10, as illustrated in FIG. 100. When the female connector 1F is released from the male connector 1M, the contact of FIG. finger 29 is pushed down. As a result, the lock arm body 22 is deformed from its original posture illustrated in FIG. 12A to a posture illustrated in FIG. 123. More specifically, the front branch 23 and the vertical portion 24a of the branch both of which act as fulcrums to thereby cause the lock arm body 22 to be deformed, and thus, as shown in Fig. 12B, the finger contact 29 comes into contact with the level of a lower surface with the extended portion 24b of the rear branch 24 (the first stage of pushing down). The finger contact 29 comes into contact with the extended portion 24b at an abutment point 31. Then, as shown in FIG. 120, the lock arm body 22 is deformed with the front arm 23 and the vertical portion 24a which both act as fulcrums and further with the stop point 31 which acts as the working point (the second step of pushing down). Thus, the locking projection 25 is released from the locking engagement portion 13 of the outer housing 10. While the locking projection 25 is kept free of the locking engagement portion 13, the female connector 1F is removed from the 1M male connector.
    [0019] As has been explained so far, the lock arm body 22 is deformed first at the first push down stage, and then at the second push down stage. More specifically, the lock arm body 22 is deformed in such a manner that the front leg 23 and the vertical portion 24a of the rear leg 24 both act as fulcrums at the first push stage to the low, and then further deformed in such a manner that the front leg 23 and the vertical portion 24a act as fulcrums and further the stop point 31 acts as a work point at the second push stage down. Thus, the locking projection 25 can travel a greater distance due to an even smaller distance from the locking release unit 26 compared to the conventional locking arm 51 illustrated in Fig. 13, which ensures that the protrusion blocking portion 25 can be reliably released from the locking engagement portion 13 of the outer casing 10. Since the locking projection 25 can be released from the locking engagement portion 13 with a small movement of the locking unit blocking release 26, it is possible to design the electrical connector 1 with a reduced height.
    [0020] In a conventional locking arm 51 shown in Figs. 13 and 17A, a blocking release unit 56 is pushed down to release a locking projection 55 from a blocking engagement portion. Thus, as shown in Fig. 17E, a lock arm body 52 is deformed with a front leg 53 and a rear leg 54 which both act as fulcrums. As shown in Fig. 17C, the lock arm body 52 is deformed until the lock arm body 52 contacts a bottom surface with an upper surface of an inner housing 50, with result that the locking projection 55 is released from the locking engagement portion of the outer housing 16.
    [0021] In the conventional lock arm 51, since the lock arm body 52 is deformed only by a force exerted on the lock release unit 56, it is necessary to cause the lock release unit 56 to move. much downwards to allow the locking projection 55 to be released from the locking engagement portion of the outer casing. Therefore, the conventional locking arm 51 is accompanied by the problem that a large gap is required between the lower surface of the lock arm body 52 and the upper surface of the inner housing 50, and the electrical connector including the conventional locking arm. 51 is therefore inevitably of great height. In contrast, the locking arm 21 in the present embodiment allows the locking projection 55 to be released from the blocking engagement portion 55 by a small displacement of the blocking release unit 26. which allows the electrical connector 1 to be smaller in height than the conventional electrical connector. The rear branch 24 is supported on the upper surface 20a of the inner housing 20 by the left arm 27a, the right arm 27b and the intermediate arm 27c. This prevents the lock arm body 22 from being deformed at a rear end in a central portion in a widthwise direction of the lock arm body 22 when the lock arm body 22 is deformed. in such a way that the front branch 23 and the vertical part 24a both act as fulcrums and furthermore the stop point 31 acts as a working point in the second downward pushing stage. . Therefore, it is possible to securely move the locking projection 25 to move thereby to release the locking projection 25 from the blocking engagement portion 13 by a small movement of the blocking release unit. 26. The intermediate branch 27c is preferably at a center between the left branch 27e and the right branch 27b. It should be noted that the intermediate portion 27c may be located in any location between the left branch 27a and the right branch 27b. The locking arm 21 may comprise a plurality of intermediate branches 27c between the left branch 27a and the right branch 27b. Alternatively, the lock arm 21 may be designed not to include the intermediate leg 27c, as shown in Figure 9. The lock projection 25 may not be a protrusion. The locking projection 25 may be any recess that can be brought into engagement with the locking engagement portion 13 of the outer housing 10. It is preferred that the gap G2 (see FIG. distal ends of the walls 28a, 28b and the locking arm body 22 or between the finger contact 29 and the extended portion 24b of the rear branch 24 is smaller than the space G1 (see Figure 7) between the body of the locking arm 22 and the surface 20a of the second housing 20. The gap G2 designed to be smaller than the gap G1 can facilitate the fact that the lock arm body 22 is deformed first at the first pushing stage towards down, and then to the second stage of pushing down.
    [0022] As illustrated in FIG. 1, the rib 14 is designed to have a length almost equal to a total length of the interior space of the cover 11 in a direction in the length direction of the outer casing 10. Rib 14 may be formed by at least a portion of a total length of the interior space. For example, the rib 14 may have a short length only at an opening of the interior space.
    [0023] As illustrated in FIG. 1, the second rib 15 is designed to have a length that begins at a distance from an opening of the outer casing 10. In a manner similar to the first rib 14, the second rib 15 can be designed to have a length equal to a total length of the interior space, or may be at least partially formed in a direction along the length of the interior space of the outer housing 10. INDUSTRIAL APPLICATION The electrical connector according to the present invention invention is suitable for an electrical connector used to make an electrical connection between devices mounted in an automobile and / or an industrial machine and so on.
