[0009]

【Example】

 Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIGS. 1, 2, 3, and 4 show one of the electric connectors A and B, and both have a lock portion. First of all, FIGS. 1 and 2 show a kind of electric connector A having a housing 1 having a non-operable lock part. In these drawings, the housing main body 2 is provided with terminals along the left-right direction. The part 3 is formed. A terminal 4 is attached to the terminal attaching portion 3 as shown by a chain line. A non-operable lock portion 6 is formed on the upper surface 5 forming the housing body 2. That is, in the center of the upper surface 5 of the housing main body 2, a base portion 7 extending between the front portion and the rear portion is formed, and the non-operable lock portion 6 is integrally formed on the base portion 7 so as to project. The non-operational lock portion 6 is composed of a steeply sloped lock surface 8 on the front side and a gently sloped guide surface 9 on the rear side, and has a substantially trapezoidal shape.

Next, FIGS. 3 and 4 show another type of electrical connector B having a housing 10 having an operation lock portion of one of the electrical connectors A and B. In these figures, the housing is shown. A terminal mounting portion 12 is formed on the main body 11 along the left-right direction. A terminal 13 is mounted on the terminal mounting portion 12 as indicated by a chain line. An operation type lock portion 15 is formed on the upper surface 14 forming the housing body 11. That is, in the center of the upper surface 14 of the housing body 11, a slightly wide pedestal 16 is formed between the front part and the rear part, and a lock is provided on the pedestal 16 via a substantially central support part 17 of the pedestal 16. The part forming plate 18 is formed in a state of being supported horizontally with respect to the base part 16. Lock bodies 19A and 19B are integrally formed on the left and right sides of the rear portion of the lock portion forming plate 18 so as to project leftward or rightward. Each of the lock bodies 19A, 19B has a wall surface on the front side thereof formed as a lock surface 20A, 20B. An operation knob 21 is formed at the front of the lock portion forming plate 18 so as to stand vertically. The operation knob 21 is pinched by a finger to raise the front portion of the lock forming plate 18 upward. For example, the lock members 19A, 19B on the rear side are lowered, and the lock members 19A, 19B on the rear side are raised by pushing the operation knob 21 downward. Allows 18 tilts. Here, an insertion gap 22 for inserting the upper surface 27 of the wafer body 24 is formed between the upper surface of the base 16 and the lower surface of the lock portion forming plate 18.

Next, the other electrical connector C having the wafer 23 will be described in detail with reference to FIGS. 5 and 6. The wafer 23 is composed of a wafer body 24 and terminals 25 mounted side by side, and one end of the terminal 25 extends into a housing mounting space 26. The size of the housing mounting space 26 is determined so that both the one housing 1 and the other housing 10 can be exchangeably accommodated without excess or deficiency. In other words, the sizes of the housings 1 and 10 on the one side are determined so that they can be accommodated in one housing mounting space 26 of one wafer 23 without excess or deficiency. Now, on the upper surface 27 of the wafer body 24, a lock receiving portion 28 for receiving the non-operable lock portion 6 of the one housing 1 and a lock receiving portion 32 for receiving the operation lock portion 15 of the other housing 10. And are formed.

First, the non-operational lock receiving portion 28 will be described. When the housing 1 having the non-operational locking portion 6 is mounted in the housing mounting space 26 of the wafer 23, the terminals 4 and 25 are completely connected. A receiving groove 29 for fitting the protruding trapezoidal lock portion 6 is formed on the upper surface 27 so as to correspond to the position of the non-operational lock portion 6 at the time. In this example, one non-operable lock portion 6 is provided near the rear side of the center of the housing 1, so that one receiving groove 29 is also formed in the upper surface 27. A slit 30 is formed from the center of the front wall of the receiving groove 29 to the front edge of the upper surface 27. The front wall 31 portion divided into two by the slit 30 functions as a lock receiving surface. Since the slit 30 is formed, the trapezoidal non-operable lock portion 6 of one of the electric connectors A and B is used as the other electric connector as described later. When the front end edge of the upper surface 27 of the wafer main body 24 of C is slid on the wafer main body 24 and trying to enter the receiving groove 29, the upper surface 27 is easily elastically deformed and easily locked. Then, when the lock bodies 19A, 19B of the other type of electrical connector B of the one electrical connector A, B slide on the lock receiving bodies 33A, 33B of the other electrical connector, the upper surface 27 is elastically deformed and locked. It's easy to do. In this case, unlike the case where the upper surface 27 is simply formed with the slit, the slit 30 which is connected to the receiving groove 29 is formed. Therefore, the space of the receiving groove 29 is also useful when the upper surface 27 is elastically deformed. Since the upper surface 27 of the wafer also has a smaller area with the downsizing of the electrical connector, the work place on the upper surface 27 is limited, and a slit is formed on the upper surface 27 outside the position connected to the receiving groove 29. Becomes difficult, but this point can be solved.

Next, regarding the operation type lock receiving portion 32, the housing 10 having the operation type locking portion 15 is mounted in the housing mounting space 26 of the wafer 23, and the terminal 13 and the terminal 25 are completely connected. The lock bodies 19A, 19B are engaged in correspondence with the positions of the operation-type lock portions 15 at the time, that is, the positions of the lock bodies 19A, 19B projecting to the left and right in the rear portion of the lock portion forming plate 18, respectively. The lock receivers 33A and 33B for fitting are formed integrally by projecting on the upper surface 27. In this embodiment, since the operation type lock portion 15 is shown as two left and right lock bodies 19A and 19B, an example in which the left and right lock receiving bodies 33A and 33B are provided correspondingly is shown. The rear wall of each lock receiving body 33A, 33B is configured as a lock receiving surface 34A, 34B, and the portion that is a gentle slope toward the front is configured as a guide surface 35A, 35B.

Next, a state in which the electric connector A having the housing 1 having the non-operable lock portion 6 is attached to the other electric connector C having the wafer 23 and the housing 1 is locked to the wafer 23 is illustrated. 7 and FIG. 8 will be described. That is, when the housing 1 is mounted in the housing mounting space 26 of the wafer 23 from the rear side of the housing 1, first, the gently inclined guide surface 9 of the non-operable lock portion 6 contacts the front edge of the upper surface 27 of the wafer 23. , Push this part up a little. At this time, since the slit 30 continuous with the receiving groove 29 is formed, the space of the receiving groove 29 and the space of the slit 30 smooth the elastic deformation of the upper surface 27, and although the friction is generated, the trapezoidal non-operable lock portion 6 is Proceed toward the receiving groove 29 of the lock receiving portion 28. That is, the insertion of the housing 1 proceeds. Then, when the terminals 4 and 25 are completely connected, the non-operational lock portion 6 is fitted into the receiving groove 29 of the lock receiving portion 28. At this time, the lock surface 8 comes into contact with the lock receiving surface 31, and the housing 1 is prevented from coming off the wafer body 24 by an unexpected external force. On the contrary, in order to intentionally remove the housing 1 from the wafer 23, the housing 1 is pulled to the front side, and the lock surface 8 contacts the lock receiving surface 31, and this portion is slightly pushed up. At this time, since the slit 30 is formed, friction is generated, but the trapezoidal non-operable lock portion 6 can be removed from the receiving groove 29 of the lock receiving portion 28.

Subsequently, the electric connector B having the housing 10 having the other operation lock portion 15 of one of the electric connectors A and B is attached to the other electric connector C having the wafer 23. A state in which the housing 10 is locked to the wafer 23 will be described with reference to FIGS. That is, the housing body 11 is inserted into the housing mounting space 26 of the same wafer 23 shown in FIGS. 7 and 8 from the rear side of the housing body 1. When the insertion is started, the upper surface 27 of the wafer main body 24 comes into the insertion gap 22 of the operation lock portion 15. Now, when the insertion is further continued, the left and right lock bodies 19A and 19B at the rear of the lock portion forming plate 18 of the operation-type lock portion 15 respectively come into contact with the left and right lock receiving bodies 33A and 33B of the lock receiving portion 32 of the wafer 23. However, since the front portions of the lock receivers 33A and 33B are formed as the inclined guide surfaces 35A and 35B, the lock portion forming plate 18 is guided by the guide surfaces 35A and 35B, and the lock portion forming plate 18 is centered on the support portion 17. Tilt so that the rear side is gradually lifted. At this time, in order to make this tilting easier, the operation knob 21 may be pushed down with a fingertip to tilt the lock portion forming plate 18 so that the rear portion is lifted. In addition, the space of the receiving groove 29 itself and the space of the slit 30 promote elastic deformation of the upper surface 27 when the lock bodies 19A and 19B slide on the lock receiving bodies 33A and 33B to facilitate locking. At this point, when the terminals 13 and 25 are completely connected, the left and right lock bodies 19A and 19B of the lock portion forming plate 18 of the operation lock portion 15 get over the lock receiving bodies 33A and 33B. 19A and 19B are lowered to the normal state, and the lock bodies 19A and 19B are locked to the lock receiving bodies 33A and 33B. That is, the lock surfaces 20A and 20B of the lock bodies 19A and 19B are locked to face the lock receiving surfaces 34A and 34B of the lock receiving bodies 33A and 33B. On the contrary, in order to detach the housing 10 having the operation type lock portion 15 from the wafer 23, the operation knob 21 portion is pushed downward so that the left and right lock bodies 19A and 19B are disengaged from the lock receiving bodies 33A and 33B. The forming plate 18 may be tilted and the housing 10 may be pulled out as it is.

Thus, according to the electrical connector C having the wafer 23, both the electrical connector A of the housing 1 having the non-operable lock portion 6 and the electrical connector B of the housing 10 having the operable lock portion 15 are provided. The above two can be mounted and the mounted state can be locked by only preparing one. Therefore, it is necessary to prepare two mating electrical connectors for the electrical connector A of the housing having the non-operable lock portion and a mating electrical connector for the electrical connector B of the housing having the operable lock portion. Therefore, a single mold is sufficient for wafer manufacturing, which can contribute to the reduction of the overall manufacturing cost.

In the above example, the main body 24 of the wafer 23 is provided with the single receiving portion 28 for receiving the non-operational lock portion 6 in the center. When there are two lock portions 6 of the gin 1, two lock receiving portions 28 may be formed on the left and right as in another example of the wafer shown in FIGS.

【effect】

 As described above in detail, according to the present invention, the electrical connector having the housing having the non-operable lock portion is mounted on the electrical connector having the wafer, and the electrical connector having the housing having the operable lock portion is provided. Even when it is mounted on an electric connector having the same wafer as the above, there is an advantage that the electric connector of the housing having the above two lock portions can be selectively fitted and held by the single electric connector. Therefore, when the use is switched from the electric connector of the housing having the non-operable lock portion to the electric connector of the housing having the operable lock portion due to various requirements in use, it can be easily carried out. Further, since the electric connector of the same wafer is sufficient, the wafer itself can be manufactured by using a single mold, which can contribute to the reduction of the manufacturing cost. Further, the non-operable lock part of one kind of electric connector, the operation lock part of one kind of electric connector, or the lock receiving part of the wafer of the other electric connector are also formed on the upper surface of the main body together. Since the top surface has a relatively large area, the above design is easy. Since the slit is formed, the trapezoidal non-operational lock part of one of the electrical connectors of one of the electrical connectors is hooked on the front edge of the upper surface of the wafer of the other electrical connector, so that the wafer body As you slide up and try to enter the receiving groove, the upper surface is likely to elastically deform and lock. Then, when the lock body of the other type of electrical connector of the one electrical connector slides on the lock receiving body of the other electrical connector, elastic deformation of the upper surface is promoted and locking is facilitated. Further, unlike the case where the slit is simply formed on the upper surface, the slit which is continuous with the receiving groove is formed. Therefore, the space of the receiving groove itself is useful when the upper surface is elastically deformed, and is easily locked.
