In the vicinity of the slightly center of the locking piece 313, a convex locking projection 311 is formed by the outer casing 310 covering the outer casing 330 of the substrate-side connector 300. This lock The projection 311 has a shape protruding from the lateral side toward the lateral direction, that is, the locking hole (recess) 13b corresponding to the cable-side connector 100, on the lateral side of the substrate-side connector 300, and the cable-side connector 100 is connected to the substrate side. When the device 300 is fitted, it is fitted to the locking hole 13b of the cable-side connector 100. Further, as shown in FIGS. 6 and 7, the casing 330 of the board-side connector 300 may be provided with tapered portions 335, 336, and 337 which are inclined toward the opening 381. By providing these tapered portions 335, 336, and 337, through the contact of the tapered projections 335, 336, 337 with the guide projections 25 provided on the lower side of the projections 38 of the cable-side connector 100, the projections 38 are provided. When guided to the opening 381, the fitting of the board-side connector 300 and the cable-side connector 100 can be made more rounded.

As shown in Fig. 9 and Fig. 10, as a substrate side connector The locking projection 311 of the convex portion of the bracket 300 is fitted to the locking hole 13b as a recess of the cable-side connector 100 and is locked to the locking hole. The cable side connector 100 and the board side connector 300 are mutually locked by the locking protrusion 311 being locked to the locking hole 13b. Since the locking piece 313 is formed by a part of the upper casing 10, it has a state of being elastically pressed by the metal, and is always elastically pressed toward the cable-side connector 100. With this elastic action, when the cable-side connector 100 is fitted to the board-side connector 300, the locking projection 311 provided on the locking piece 313 is snap-fitted to the locking hole 13b. The locking of the cable-side connector 100 and the board-side connector 300 is maintained by the elastic action of the locking piece 313, so that the locking projection 311 is not removed from the locking hole 13b.

After the lock, the force acts on the cable side connector 100 In the case of the locking direction of the board-side connector 300, a part of the locking protrusion 311, that is, the periphery of the protruding lower side portion 321 of the locking protrusion 311 fitted to the locking hole 13b, particularly near the corners of the both ends thereof, and the locking hole 13b A part of the lower side portion 17a of the locking hole 13b, in particular, the vicinity of the corner portions 17b, 17c at both ends thereof collides with each other, and the force for releasing the force is generated.

As the cable side connector 100 and the board side connector In the case of the lock of 300, there are mainly two cases. As described with reference to FIG. 4(a), in the case where the cable-side connector 100 and the substrate-side connector 300 are intended to be pulled by the draw tape, another case is as described with reference to FIG. 4(c), without intentional carelessness. The cable side connector 100 is pulled away from the substrate side connector 300 through the cable 4.

Of course, in the former case, it is more sleek to unlock, In the latter case, it is better to prevent the lock from being released. Therefore, in the present invention, the resistance of the front side of the cable-side connector 100 in the locking projection 311 and the locking hole 13b is set to be smaller than the resistance of the rear side.

Referring mainly to Figures 9 and 10, the description is used to generate the desired A structural example of resistance. In this configuration example, the substrate side connector 300 is used to generate a desired resistance. As shown in FIG. 9 and the like, the locking projection 311 provided at the center of the locking piece 313 is provided in a state of being swelled from the locking piece 313. As a result, the locking projection 311 has a protruding portion along the extending direction toward the locking hole 13b side at least at the lower side portion 321 thereof. The entire projection has a bilaterally symmetrical shape, but it is asymmetric with respect to the corner. That is, the chamfering process is performed on the corner portion 316 on the front side in the horizontal direction. This chamfering process is not performed on the corner portion 329 on the rear side. Therefore, the locking projection 311 has a left-right asymmetrical shape with respect to the chamfered portion (316). When the locking of the cable-side connector 100 and the board-side connector 300 is released, the corner portion 316 which is chamfered and the corner portion 329 which is not chamfered are both portions which collide with the locking hole 13b to generate resistance. However, by changing the degree of protrusion of the corner portion, there is a difference in resistance between the cable side connector 100 or the front side and the rear side of the board side connector 300.

For example, as shown in FIG. 9, the harness is used (not shown) The cable side connector 100 is lifted upward on the front side thereof (in the direction of the arrow [e] in the figure), and since the draw tape is provided on the front side of the cable side connector 100, the center of rotation becomes more than the draw tape As a result, in the collision portion around the periphery of the lower side portion 321 of the locking projection 311 and the periphery of the lower side portion 17a of the locking hole 13b, the periphery of the corner portion 316 of the locking projection 311 collides with the periphery of the front side corner portion 17b of the locking hole 13b. In the vicinity of the portion, a larger resistance is generated in the vicinity of the corner portion 329 of the locking projection 311 and the vicinity of the collision portion around the rear corner portion 17c of the locking hole 13b. However, even in this case, since the corner portion 316 of the front side locking projection 311 is chamfered, the resistance is reduced, and as a result, the cable side connection can be more smoothly released than when the chamfering process is not performed. The device 100 is locked to the substrate side connector 300.

In addition, the cable is not intentionally inadvertently passed through the cable 4 When the force acting in the direction in which the side connector 100 is pulled away (the direction of the arrow f in the figure) is applied to the cable side connector 100, the center of rotation becomes the front side of the cable 4, and as a result, a collision portion around the lower side portion 321 of the locking projection 311 and the periphery of the lower side portion 17a of the locking hole 13b In the vicinity of the collision portion around the corner portion 329 of the locking projection 311 and the periphery of the rear corner portion 17c of the locking hole 13b, a collision occurs around the periphery of the corner portion 316 of the locking projection 311 and the periphery of the front corner portion 17b of the locking hole 13b. Greater resistance in the vicinity. However, even in this case, since the corner portion 329 of the locking projection 311 on the rear side is not chamfered, the resistance between the locking projection 311 and the locking hole 13b is large, and as a result, the cable side connector 100 does not. The locking is maintained from the substrate side connector 300.

Referring to Figure 11, the other used to generate the desired resistance is illustrated. Configuration example. In this configuration example, the desired resistance is generated by the cable side connector 100'. Fig. 11 is a side view showing the side of the cable-side connector in the same manner as Fig. 5, and similar to Fig. 5, the shape and figure of the locking hole 13b' of the second locking piece 13' provided in the cable-side connector 100'. The locking holes 13b shown in Fig. 5 are different. Further, in the modification of Fig. 11, the inclined portion 28' which is inclined toward the side of the locking projection 311 is provided only at the lower edge portion 17a' of the locking hole 13b', particularly the peripheral edge portion of the corner portion 17b' of the front side thereof, with respect to Therefore, such an inclined surface is not provided around the corner portion 17c' of the rear side.

In this case, for example, as shown in FIG. 9, the cable-side connector 100 is lifted upward (in the direction of the arrow [e] in the figure) on the front side thereof by a draw tape (not shown), since the draw tape is pulled. Provided on the front side of the cable-side connector 100, the center of rotation becomes the rear side of the cable tie, and as a result, in the collision portion around the lower edge portion 321 of the locking projection 311 and the periphery of the lower edge portion 17a' of the locking hole 13b' In the vicinity of the collision portion around the front side corner portion 17b' of the locking hole 13b' and the periphery of the front side corner portion of the locking projection 311, the rear side corner portion 17c' of the locking hole 13b' is formed and the rear side corner portion of the locking projection 311 is formed. Surrounding Greater resistance near the collision portion. However, even in this case, since the corner portion 17b' of the front side locking hole 13b' is provided with the inclined surface 28', the resistance is reduced, and as a result, it can be more smoothly released than when the inclined surface is not provided. The cable side connector 100 is locked to the substrate side connector 300.

In addition, the cable is not intentionally inadvertently passed through the cable 4 When the force acting in the direction in which the side connector 100 is pulled away (the direction of the arrow f in the figure) is applied to the cable side connector 100, the center of rotation becomes the front side of the cable 4, and as a result, In the collision portion of the periphery of the lower side portion 321 of the locking projection 311 and the periphery of the lower side portion 17a' of the locking hole 13b', the collision portion around the periphery of the rear side corner portion 17c' of the locking hole 13b' and the rear corner portion of the locking projection 311 In the vicinity, a larger resistance is generated in the vicinity of the collision portion of the front side corner portion 17b' of the lock hole 13b' and the vicinity of the front side corner portion of the lock protrusion 311. However, even in this case, since the inclined portion is not provided at the lower side portion 19 of the locking hole 13b on the rear side, the resistance between the locking projection 311 and the locking hole 13b is large, and as a result, the cable side connector 100 does not. The connector 300 can be pulled away from the substrate side to maintain the lock.

Furthermore, in the example shown in Fig. 11, only the corner on the front side 17b' is provided with the inclined surface 28', but instead of this structure, as shown in Fig. 5, the inclined surface of the front side and the rear side in the horizontal direction is provided, and the inclination angle of the inclined surface 28 around the corner portion 17b of the front side is made. The inclination angle of the inclined surface 28 around the corner portion 17c on the rear side is small, that is, the inclined surface on the front side is set to be gentle, and the same effect can be obtained.

The invention developed by the inventors of the present invention has been specifically described above based on the embodiments. However, the present invention is not limited to the above embodiments, and Various changes can be made without departing from the scope of the technical idea.

For example, in the above-described embodiment, the cable-side connector 100 is provided with the convex portion 311, and the substrate-side connector 300 is provided with the concave portion 13b. Alternatively, the cable-side connector may be provided with a concave portion and the substrate-side connector may be provided with a convex portion. .
