Assembly can also be possible.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1 in an exploded manner, the memory card adapter 10 according to the embodiment has a first housing 20 and a second housing 30 formed of insulating plastic, and has a spring property and conductivity such as phosphor bronze. It has a plurality of terminals 40 formed by punching a thin metal plate and a metal shell 50 formed by punching a metal plate such as a stainless plate. A perspective view of the completed memory card adapter 10 is shown in FIG. 2, and a bottom view is shown in FIG.

  As shown in FIG. 4, this memory card adapter 10 has one standard, that is, a card connector 70 corresponding to the memory card 60 before miniaturization, and another standard smaller than the one standard. Used to connect the memory card 80. The card connector 70 is provided with a card receiving cavity so that the memory card 60 can be inserted as shown by an arrow 61, and a contact piece (not shown) of the conductive terminal 71 extends into the card receiving cavity. When the memory card 60 is inserted into the card receiving cavity, the contact piece engages with a contact pad provided on the lower surface of the front end of the memory card 60 in the insertion direction.

  The memory card adapter 10 according to the embodiment is configured in accordance with the memory card 60 before the miniaturization. The memory card adapter 10 receives the miniaturized memory card 80 as indicated by an arrow 11 and is connected to the card connector 70. It can be inserted as indicated by arrow 12. When inserted into the card connector 70, the terminals 71 of the card connector 70 and the memory card 80 can be electrically connected.

  The first housing 20, the second housing 30 and the metal shell 50 constitute a holder 90 of a memory card 80 that is miniaturized. That is, the first housing 20 is connected to the front end side, the second housing 30 is connected to the rear end side, and the second housing 30 on the rear end side is assembled so as to cover the metal shell 50. And the metal shell 50 cooperate to form a card receiving cavity 91. The card receiving cavity 91 is opened at the rear end to form a card insertion slot 92.

  The terminal 40 is formed into a shape as shown in FIGS. A plurality of terminals 40 are mounted together in the second housing 30 in a state where the terminals 40 are arranged in parallel in the longitudinal direction of the carrier 41, and the carrier 41 is separated after mounting. Each terminal 40 and the carrier 41 are integrally connected by a connecting piece 45 interposed between the pad piece 44 and the carrier 41 as shown in an enlarged manner in FIG. The connecting piece 45 is narrower than the width of the pad piece 44. In FIG. 6, a line 46 shown on the connecting piece 45 represents the position of separation. Each terminal 40 has a mounting piece 42 at an intermediate portion, a contact piece 43 extends from one end of the mounting piece 42, and a pad piece 44 extends from the other end. The mounting piece 42 is supported by the second housing, and the pad piece 44 is supported by the first housing 20.

  Hereinafter, details of each element will be described with reference to FIGS.

  As shown in FIG. 10, the second housing 30 has a bottom wall 31, side walls 32 erected on both side edges of the bottom wall 31, and both sides on the front edge of the bottom wall 31 (left front in FIG. 10). A terminal mounting wall 33 provided so as to connect the walls 32 is integrally formed. A plurality of inverted T-shaped terminal mounting holes 34 are provided in parallel in the terminal mounting wall 33 so as to penetrate in the front-rear direction.

  A plurality of terminals 40 in the state shown in FIG. 5 are attached to the second housing 30 by press-fitting. The contact pieces 43 are attached in a lump so as to be inserted into the terminal attachment holes 34 from the side. As shown in an enlarged view in FIG. 11, an entrance portion of the terminal mounting hole 34, that is, a portion opened at the front end surface 36 of the second housing 30, for batch mounting of a plurality of terminals 40, A chamfered portion 341 is formed. This is because when the terminal 40 is mounted, each contact piece 43 is surely drawn into the corresponding terminal mounting hole 34 so that the contact piece 43 is not deformed.

  When the plurality of terminals 40 are mounted to the state shown in FIG. 13, the barbs 421 on the side edges of the mounting pieces 42 constituting the intermediate portion of each terminal 40 bite into the inner wall of the terminal mounting hole 34 and are locked. The contact piece 43 extends in a cantilever shape on the bottom wall 31 beyond the terminal mounting wall 33 as shown in the figure. On the other hand, the pad piece 44 extends in front of the front surface of the terminal mounting wall 33.

  After the plurality of terminals 40 are collectively attached to the second housing 30 in this way, the connecting piece 45 connecting each terminal 40 and the carrier 41 is cut at the position of the line 46 as shown in FIG. Then, the carrier 41 is separated, and the first housing 20 is mounted on a pad piece 44 extending in front of the second housing 30 as shown in FIG. 8 and 9 show a plan view of the terminal 40 after the connecting piece 45 is cut off at the position of the line 46.

  As can be understood from FIG. 4, the first housing 20 is formed in a shape substantially the same as the outer shape of the front end portion in the insertion direction of the memory card 60 before downsizing. As in the case of the second housing 30, a plurality of terminal mounting holes 21 (FIG. 17) are provided in parallel and open at the rear end surface 22 (FIG. 1) of the first housing 20. The terminal mounting hole 21 is a flat hole substantially equal to the cross-sectional shape of the pad piece 44. A chamfered portion (not shown) is provided in the opening of the rear end surface 22 in the same manner as the terminal mounting hole 34 of the second housing 30 so that the pad piece 44 can be guided smoothly and reliably.

  As shown in FIGS. 3 and 17, a notch groove 23 is formed in the lower surface of the front end side of the first housing 20 in accordance with each terminal mounting hole 21, and communicates with the front end portion of the terminal mounting hole 21. ing. A hook-like connecting arm 24 extends rearward from both sides of the rear end surface 22 of the first housing 20, and engages with connecting grooves 35 provided on both sides of the terminal mounting wall 33 of the second housing 30. Thus, the first housing 20 and the second housing 30 can be connected together.

  Further, the terminal 40 is provided with a crank-shaped bent portion 47 at a portion where each mounting piece 42 and pad piece 44 are continuous, as shown in FIGS. 5 and 18. For this reason, in the state where the first housing 20 is completely mounted as shown in FIG. 15 and connected to the second housing 30, the rising pieces 471 of the bent portions 47 provided in the terminals 40 are as shown in FIG. It is sandwiched between the rear end surface 22 of the first housing 20 and the front end surface 36 of the second housing 30. Accordingly, each terminal 40 is firmly held by locking in the terminal mounting hole 34 of the second housing 30 and clamping between the first housing 20 and the second housing 30.

  The width of the terminal mounting hole 21 of the first housing 20 substantially matches the width of the pad piece 44 of the terminal 40. On the other hand, the width of the notch groove 23 is narrower than the width of the pad piece 44. Accordingly, when the first housing 20 is completely assembled, the center portion of the pad piece 44 is exposed to the outside through the notch groove 23 on the lower surface of the front end portion of the first housing 20 to form the contact pad 93. The contact pads 93 are electrically engaged with contact pieces (not shown) of the terminals 71 of the card connector 70 described with reference to FIG.

  The side edge portion at the distal end portion of the pad piece 44 is accommodated in the terminal mounting hole 21 without being exposed to the notch groove 23. The width of the connecting piece 45 connecting the terminal 40 and the carrier 41 is set in the range of the side edge portion that is not exposed. As best shown in FIG. 6, the connecting piece 45 has a relatively wide width on the carrier 41 side to ensure the strength as the connecting piece 45, while the portion 451 continuous with the pad piece 44 is The width of the side edge portion of the pad piece 44 that is not exposed is substantially the same narrow width. Therefore, the cutting edge generated by cutting the connecting piece 44 at the position of the line 46 is not involved in the configuration of the contact pad 93.

  The front edge of the pad piece 44 of the terminal 40 is such that the cut edge generated by the separation after the batch mounting is not involved in the configuration of the contact pad 93. Therefore, the contact piece of the terminal 71 of the card connector 70 When engaging with the contact pad 93, there is no possibility that the contact piece will be damaged by the contact pad 93, and there is no possibility that the plated surface will be peeled off. As shown in FIG. 5, surface processing such as plating after punching and molding a plurality of terminals 40 in a parallel state is possible, the surface is smoothed by surface processing to improve corrosion resistance, and the card connector The frictional resistance at the time of engagement with the contact piece 70 is made small. The cut edge has a broken surface, and even if this portion is plated, the wettability of the plating is poor and it is difficult to process. In addition, a chamfered portion 441 is also formed at the same time after the punching on the lower side of the edge of the pad piece 44. By forming the chamfered portion 441, the card connector 70 can be more smoothly engaged with the contact piece.

  After the first housing 20 is attached to the pad piece 44 and connected to the second housing 30, the metal shell 50 is finally assembled from the rear end side of the second housing 30 as shown in FIG. Has been completed.

  As shown in FIG. 1, the metal shell 50 has a cross section formed into a C channel shape. A pair of side plates 52 facing the top plate 51 are continuous. The side plate hangs down from the edge of the top plate 51 with an L-shaped cross section. The top plate 51 has substantially the same outer shape as the bottom wall 31 of the second housing 30. Further, the side plate 52 has substantially the same height as the side wall 32 of the second housing 30.

  Further, a tongue-like piece 53 extending forward is provided at the front end of the top plate 51. The tongue 53 extends toward the first housing 20, and when the memory card adapter 10 is completed, as shown in FIGS. It fits into a tongue-like piece receiving groove 25 provided so as to open in the end face 22. By fitting the tongue-like piece 53 into the tongue-like piece receiving groove 25 of the first housing 20 in this way, the resistance to bending and twisting of the connecting portion of the first housing 20 and the second housing 30 is improved. .

  Further, the side plate 52 of the metal shell 50 is provided with an engagement window 5 21, which fits with the engagement boss 241 provided to protrude from the outer surface of the connecting arm 24 of the first housing 20, and thereby the second housing 30. The metal shell 50 assembled to the first housing 20 is made to have integrity even with the first housing 20.

  The holder 90 is finally completed by assembling the metal shell 50 to the second housing 30 in this way, and the metal shell 50 and the second housing 30 cooperate to receive a card on the rear end side of the holder 90. A cavity 91 is formed. The upper side of the card receiving cavity 91 is partitioned by the top plate 51 of the metal shell 50, and the lower side is partitioned by the bottom wall 31 of the second housing 30. Further, both sides are partitioned by a side wall 32 of the second housing 30. As a matter of course, the hollow shape of the card receiving cavity 91 substantially matches the cross-sectional outer shape of the miniaturized memory card 80.

  A contact piece 43 of the terminal 40 faces the front portion of the card receiving cavity 91 in a cantilever shape. When the miniaturized memory card 80 is inserted through the card insertion opening 92 of the card receiving cavity 91, the contact pads (not shown) of the memory card 80 and the contact pieces 43 correspond to each other in a one-to-one relationship and are electrically connected to each other. Can be engaged.

  In the case of this embodiment, among the plurality of parallel terminals 40, the terminals 40 on both sides are ground terminals. For this reason, the contact piece 43 is made longer than the terminals 40 arranged on the inner side (see FIGS. 5, 7, and 8. The inner terminal 40 also changes the length of the contact piece 43 in accordance with the connection sequence. .) And the spring contact 48 is cut and raised in the base part (mounting piece 42 side) of the pad piece 44 of the terminal 40 used as the ground terminal on both sides.

  A connecting groove 26 is formed between the tongue-shaped piece receiving groove 25 and the terminal mounting hole 21 of the first housing 20 so as to correspond to the spring contact 48 as shown in FIG. When the tongue-like piece 53 of the metal shell 50 is fitted into the tongue-like piece receiving groove 25, the spring contact 48 and the tongue-like piece 53 are electrically engaged with each other, and the terminals 40 on both sides serving as ground terminals. And the metal shell 50 are brought into conduction so that they can have the same potential.

  As described above, in the memory card adapter 10 of the embodiment, the contact piece 43 provided at one end of the terminal 40 is engaged with the contact pad of the miniaturized memory card 80 and the pad provided at the other end of the terminal 40. Since the contact pad 93 that engages with the terminal 71 of the card connector 70 is formed by the piece 44 and there is no internal substrate in the holder 90, the number of parts can be reduced, and the terminal and the internal substrate can be reduced. A mounting process such as a soldering process is not required, and manufacturing can be simplified and facilitated.

  Since some of the plurality of terminals 40 (two in the embodiment) are provided with spring contacts 48, and the spring contacts 48 are directly engaged with the metal shell 50 so as to be electrically connected to each other. This also contributes to the reduction of the number of parts.

  Further, since the front end portion of the memory card adapter 10 in the insertion direction is constituted by the first housing 20 which is a single molded product, accurate modeling can be performed, and processes and facilities such as conventional fusion of the upper and lower housings are possible. Can be omitted. And since modeling can be performed correctly, a fitting condition with the connector 70 for cards can also be improved, and the reliability of a connection can be improved.

  Further, since the cut end surface (fracture surface) due to the separation generated at the end edge portion of the pad piece 44 of the terminal 40 is not related to the configuration of the contact pad 93, the surface of the edge portion related to the configuration of the contact pad 93 is used. Can be processed and processed. For this reason, the durability can be improved, and the mating terminal, that is, the contact piece of the card connector 70 can be prevented from being damaged, and the durability of the card connector 70 can also be improved.

  In addition, since the housing to which the terminals 40 are mounted is divided into the first housing 20 and the second housing 30, not only can a plurality of terminals 40 be mounted together, but also an easy assembly, automatic assembly by a machine. Can also be possible. The chamfered portions 341 provided in the openings of the terminal mounting holes 21 and 34 of the respective housings 20 and 30 are particularly effective when this automatic assembly is performed, and the terminal mounting holes 21 and 25 can be securely connected without buckling the terminals 40. 34 can be invited.
