Formed by continuously cutting from the middle to the upper surface of the module main body 102 are provided. Furthermore, a substrate 105 is attached to the bottom surface of the module body 102 with an adhesive 106, and a plurality of contact pads 104 serving as contacts are formed on the side surfaces of the substrate 105 in the vertical direction.

  FIG. 4 shows a connector 110 for mounting the module 101. The connector 110 is formed in a bowl-like body having a hollow portion 110a opened upward, and the bottom portion 110b of the connector 110 is notched in the vicinity of the four sides. .. Are formed, and a plurality of contact pins 111, 111... Serving as contact terminals are arranged on the inner side surface of the hollow portion 110 a in parallel with the vertical direction.

  The connector 110 is provided with engagement terminals 112, 112... Corresponding to the engagement recesses 102 a, 102 a. The engagement terminals 112, 112... Are bent in a substantially U shape, and one end is fixed to the inner surface of the hollow portion 110a of the connector 110, and protrudes toward the hollow portion 110a near the upper end on the other end side. The contact protrusion 112a bent as described above is formed. The contact protrusion 112a is engaged with the engagement recesses 102a, 102a, and the like so that the module 101 can be prevented from coming off when the module 101 is inserted into the hollow portion 110a to a predetermined position. Yes. In addition, the C surface 110b is formed in the corner | angular part of the hollow part 110a of a bowl-shaped body in the shape corresponding to the C surface 102b of the said module 101. As shown in FIG.

  Further, the connector 110 is mounted on a printed wiring board (not shown), and the contact pin 111 is connected to the control circuit of the module device via a wiring pattern. For this reason, the hook-shaped connector 110 needs to be mounted at a position corresponding to the wiring pattern. Therefore, the module 101 also needs to be connected to a position that correctly corresponds to the wiring pattern. If the module 101 is inserted in an incorrect position, the control circuit may malfunction or, in the worst case, the control circuit may be destroyed. Thus, when the module 101 is fitted to the connector 110, it is required to have an erroneous fitting prevention structure.

And when attaching the module 101 to the connector 110, as shown in FIG. 4, the module 101 is assembled so that it may fall into the hollow part 110a from the upper side of the connector 110. As shown in FIG. At this time, the module 101 is assembled so that the C surface 102 b of the module 101 faces the C surface 110 b of the connector 110. Incorrect fitting is prevented by incorporating in this direction.
