Description

  The present invention relates to a connector device for a composite memory card, and more particularly to a connector device for a composite memory card that is used in a portable terminal or the like and can be applied to memory cards of different sizes.

  In recent years, memory cards have been used for storing data of portable terminals such as mobile phones and digital cameras. The memory card is inserted into a memory card connector device and used.

  At present, several types of memory cards are commercially available and are commercially available. Although the shape of each memory card is similar, the external dimensions are different.

  From the standpoint of the user of the portable terminal and the digital camera, it is desirable that any memory card can be used. If a plurality of memory card connector devices are provided for each type of memory card, several types of memory cards can be supported. However, since it is important for the portable terminal and the digital camera to be small, it is difficult to provide a plurality of memory card connector devices. Accordingly, a connector device for a composite memory card has been developed that is compatible with two types of memory cards, and some have been put into practical use.

  1A and 1B show an example of a conventional composite memory card connector device 30. FIG. Y1-Y2 is the longitudinal direction, X1-X2 is the width direction, and Z1-Z2 is the height direction. Y1 is the direction in which the memory card is inserted. The composite memory card connector device 30 includes a first memory card 10 shown in FIGS. 3A, 3B, 4A, 4B, and 4C, and FIGS. This is a configuration that can be applied to any of the second memory cards 20 shown in (D) and FIGS. 4 (D), (E), and (F).

  The first memory card 10 has a width W1, a length L1, and a thickness T1, and the second memory card 20 has a width W2, a length L2, and a thickness T2. Comparing the dimensions of the outer shape, at first glance, the length L2 is about twice the length L1, the lengths are different, and the widths and thicknesses are substantially the same. Strictly speaking, the width W2 is slightly larger than the width W1, and the thickness T2 is slightly larger than the thickness T1. L2> L1, W2> W1, and T2> T1. The first and second memory cards 10 and 20 have different external shapes and mainly different lengths.

  Reference numerals 11 and 21 denote front end sides in the insertion direction. 12 and 22 are rear end sides in the insertion direction. Reference numerals 13 and 23 are contacts. The lower surface of the first memory card 10 has a step portion 14 that is one step lower on the front end side 11, and contacts 13 are arranged on the lower step portion 14. Similarly, the lower surface of the second memory card 20 has a stepped lower portion 24 formed in a comb-like shape on the front end side 21, and contacts 23 are arranged in the lower stepped portion 24.

  Pay attention to the tip side. The first memory card 10 has a front end side width W1A narrower than the width W1, and has a shoulder 15 on the left side. The second memory card 20 has a chamfered portion 25 on the left side.

  The composite memory card connector device 30 has a structure in which a housing 31 is provided with a first memory card contact 32, a second memory card contact 33, and a plate-like rotating member 34. Reference numeral 35 denotes a memory card insertion slot. The first and second memory card contacts 32 and 33 are arranged corresponding to the lengths of the first and second memory cards 10 and 20, and the contact portion 32 a of the first memory card contact 32. In the middle, the contact portion 33a of the second memory card contact 33 is located on the back side. The first memory card contact 32 extends obliquely from the memory card insertion slot 33 side in the Y1 direction toward the Z1 direction. The plate-like rotation member 34 is supported with the vicinity of the memory card insertion slot 35 as a rotation fulcrum, and is placed on the oblique first memory card contact 31.

  When the first memory card 10 having the thickness T1 is inserted and inserted to the final position through the memory card insertion slot 35, the contact 13 becomes the contact portion as shown in FIGS. 2 (A) and 2 (B). 32a is contacted.

  When the second memory card 20 having the thickness T2 is inserted and inserted to the final position through the memory card insertion slot 35, the contact 23 becomes the contact portion 33a as shown in FIGS. Touched.

  The contact 23 and the contact portion 32a operate as follows. Since the thickness T2 of the second memory card 20 is thicker than the thickness T1 of the first memory card 10, the second memory card 20 itself pushes the plate-shaped rotating member 34 in the Z2 direction, The memory card contact 32 is bent in the Z1 direction, and the contact portion 32a is displaced in the Z2 direction. Accordingly, the contact 23 passes in the Y1 direction above the contact portion 32a without contacting the contact portion 32a. Even when the second memory card 20 is removed, the first memory card contact 32 is maintained in a state of being bent in the Z1 direction, and the contact 23 contacts the contact portion 32a above the contact portion 32a. Pass in the Y2 direction.

The composite memory card connector device 30 is configured to identify the difference in thickness between the first and second memory cards 10 and 20 by the rotation member 34 being displaced in the thickness direction of the memory card.
JP 2003-288932 A

  The plate-like rotating member 34 does not reach the contact portion 32a. Therefore, when the second memory card 20 is inserted and mounted, the upper portion of the contact portion 32a is exposed. Further, the second memory card 20 is not guided by the rotating member 34 in the contact portion 32a.

  For this reason, a part of the second memory card 20 may hit the contact part 32a depending on the situation. If a part of the second memory card 20 hits the contact part 32a, in some cases, The contact part 32a will be bent. If the bent contact portion 32a exists, the contact 23 may come into contact with the contact portion 32a during the insertion of the second memory card 20, and when the contact 23 comes into contact with the contact portion 32a, An abnormal signal is exchanged between the second memory card 20 and the contact 23.

  In the state where the second memory card 20 is mounted, the first memory card contact 32 is forcibly bent to a horizontal state as shown in FIG. While the device 30 is being used for a long time, the first memory card contact 32 is permanently deformed in the horizontal direction and the position of the contact portion 32a is displaced in the Z2 direction, whereby the first memory card 10 is removed. When attached, the contact between the contact 13 and the contact portion 32a may be incomplete.

  Accordingly, an object of the present invention is to provide a composite memory card connector device made in view of the above points.

Therefore, in order to solve the above-described problem, the present invention provides a housing in which a single insertion slot and a first card having a short length and a second card having a long length can be inserted,
A contact for a second card disposed in the housing corresponding to the second card;
A first card contact disposed in the housing in correspondence with the first card and positioned closer to the insertion slot than the second card contact;
When the second card is inserted, the second card is operated by the inserted second card so that the second card moves away from the contact portion of the contact for the first card. A contact protection member
The first card is mounted in contact with the contact portion of the first card contact, and the second card is inserted beyond the contact portion of the first card contact. In the connector device for a composite card that is configured to be in contact with the contact for the card,
The contact protection member supports the second card with the contact protection member itself in a portion where the second card exceeds the contact portion of the contact for the first card,
The contact protection member has a shape having a slit corresponding to the contact portion of the contact for the first card,
A lock mechanism for locking the contact protection member in an inclined state when the second card is inserted;
When the first card is inserted, the contact portion of the first card contact protrudes from the slit, and when the second card is inserted, the lock mechanism Thus, the contact protection member is locked in an inclined state and is positioned higher than the contact portion of the contact for the first card .

  Since the second card is configured to support the second card with the contact protection member itself in a portion beyond the contact portion of the contact for the first card, the second card is inserted and removed. The reliability of preventing the second card from interfering with the contact portion of the contact for the first card can be improved.

  Next, an embodiment of the present invention will be described.

Further, as shown in FIG. 6C, the cam 95 is substantially in contact with the protruding piece 62. The X2 side portion of the card identification member 100 protrudes into the memory card insertion slot 52.

  Next, the operation when the first memory card 10 or the second memory card 20 is inserted and inserted into the composite memory card connector device 50 will be described.

  The composite memory card connector device 50 is configured to identify the difference in thickness between the first and second memory cards 10 and 20 by the card identification member 100 being displaced in the width direction of the memory card.

  First, the operation when the first memory card 10 is inserted and mounted will be described.

  10A and 11 show a state where the first memory card 10 is mounted. FIG. 10B shows the first memory card 10 omitted.

  The first memory card 10 is fitted to the guide groove 102 of the card identification member 100 on the X1 side, and is inserted to a predetermined position without moving the card identification member 100 in the X1 direction. Touched.

  Further, the first memory card 10 is inserted while pushing the slide member 80 in the Y1 direction while bending the spring 85 with the shoulder portion 15 on the X2 side.

  Next, an operation when the second memory card 20 is inserted and mounted will be described.

  FIG. 12A shows an initial state in which the second memory card 20 is inserted. FIG. 12B and FIGS. 13A to 13C show the initial state in which the second memory card 20 is inserted, with the second memory card 20 omitted.

  FIG. 14A and FIG. 16 show a state where the second memory card 20 is inserted and mounted to the final position. FIG. 14B and FIGS. 15A to 15D show a state in which the second memory card 20 is mounted with the second memory card 20 omitted.

  Since the second memory card 20 is thicker than the width of the guide groove 102, the second memory card 20 does not fit into the guide groove 102, and pushes the inclined surface 104 to move the card identification member 100 in the X1 direction. Inserted into. At this stage, the contact protection member 90 does not move, and only the card identification member 100 is moved.

  When the second memory card 20 is further inserted, the chamfered portion 25 on the X2 side of the second memory card 20 is guided by the inclined surface portion 81 on the Y2 side of the slide member 80, and the second memory card 20 is inserted. Is moved in the X1 direction, and the card identification member 100 is pushed by the second memory card 20 and further moved in the X1 direction.

  At this time, the contact protection member 90 together with the card identification member 100 is moved in the X1 direction by a distance corresponding to the pitch P. At this time, the cam 95 hits the projection piece 62 and pushes it to displace the projection piece 62 in the Z2 direction as shown in FIG. Similarly, as shown in FIG. 15C, the cam 95 is in a state of riding on the upper surface of the first memory card contact 60. As a result, the first memory card contact 60 is pushed down in the Z2 direction. The contact portion 61 is displaced in the Z2 direction and sinks into the opening 93, and as shown in FIGS. 15D and 16, the upper portion is covered and protected by the crosspiece 94.

  The second memory card 20 is inserted between the slide member 80 and the card identification member 100 in the Y1 direction, pushes the hook portion 82 of the slide member 80 on the distal end side 21, and bends the spring 85, while FIG. 16 is inserted to the final position shown in FIG. While the second memory card 20 is positioned between the slide member 80 and the card identification member 100 and inserted in the Y1 direction, the contact protection member 90 is maintained in the state shown in FIG.

  Therefore, before the contact 23 of the second memory card 20 reaches the position of the contact portion 61, the contact portion 61 sinks into the opening 93 and the crosspiece 94 covers the contact portion 61 to protect the contact portion 61. This state is maintained thereafter.

  For this reason, when the second memory card 20 is inserted, the second memory card 20 and the contact 23 are supported by the crosspiece 94 covering the contact portion 61 and pass above the second memory card 20. Also when the second memory card 20 is removed, the second memory card 20 and the contact 23 are supported by the crosspiece 94 covering the contact portion 61 and pass through this upper side. Therefore, the second memory card 20 has higher reliability than the conventional one in preventing the second memory card 20 from interfering with the contact portion 61. As a result, the second memory card 20 is not caught by the contact portion 61 and the contact portion 61 is not bent.

  Further, after the second memory card 20 is inserted to some extent, the cam 95 does not push the protruding piece 62 but the cam 95 rides on the upper surface of the first memory card contact 60. Therefore, the first memory card contact 60 is stably maintained in the depressed state.

  Note that when the first and second memory cards 10 and 20 are removed, an operation of slightly pushing in the first and second memory cards 10 and 20 that are mounted is performed. By this operation, the slide member 80 is unlocked, the slide member 80 is returned in the Y2 direction by the force of the spring 85, and the first and second memory cards 10 and 20 are pushed back in the Y2 direction.
