Hereinafter, a configuration of a preferred embodiment of a dual card socket connector according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in the drawings, the case 10 forms the skeleton of the connector of the embodiment of the present invention, and a metal shell 10 'is installed to cover the top of the case 10. Thus, the case 10 and the shell 10 'form the overall appearance and skeleton. Of course, the case 10 and the shell 10 ′ may be housed therein to form a separate component.

The case 10 is formed in a substantially flat plate shape with the outer wall 11 and the rear end wall 11 ′ protruding at a predetermined height to form a predetermined space between the shell 10 ′ and the outer wall 11 and the rear end wall 11 ′. A guide side wall 12 is formed inside the upper surface of the case 10 so as to extend in parallel with the outer wall 11. The guide side wall 12 also serves to guide the movement of the tray 30 to be described below. The guide side wall 12 is not continuously connected from the front end to the rear end of the case 10. That is, it is not formed in some sections.

The installation end 14 is formed relatively thick in the front end and the rear end of one side of the outer wall 11, respectively. The front and rear ends of the guide rods 26 to be described below are fixed to the installation end 14, respectively. A switch opening 16 is formed on the opposite outer wall 11 provided with the installation end 14. The switch opening 16 is installed through the operation lever 50 to be described below.

The lever rotation shaft 17 and the cam rotation shaft 18 are located in a relatively narrow area between the outer wall 11 and the guide side wall 12, that is, a space in which the tray 30 to be described below is located. Each is formed to protrude in a state spaced apart a predetermined distance. The lever rotation shaft 17 is the rotation center of the operation lever 50 to be described below, the cam rotation shaft 18 is the rotation center of the linkage cam 60 to be described below.

In the case 10, the guide step 20 is formed side by side in the moving direction of the tray 30 on the bottom surface of the space where the tray 30 is located. The guide step 20 serves to guide the movement of the tray 30.

In the relatively low region corresponding to the guide step 20, the first contact terminals 22 and the second contact terminal (in order from the rear end of the case 10 toward the tip in the moving direction of the tray 30, respectively) 24) are arranged. The number and arrangement direction of the contact terminals 22 and 24 are designed to suit the electrical connection with the card used.

 On the other hand, the guide rod 26 is provided along one side outer wall 11 of the case 10. Both ends of the guide rod 26 are respectively connected to the installation end 14. The guide rod 26 passes through the guide end 33 of the tray 30 to be described below. The guide rod 26 serves to guide the movement of the tray 30. One side of the guide rod 26 is provided with a protruding elastic member 28. The protruding elastic member 28 acts as a cylindrical coil spring in a direction in which the tray 30 protrudes from the inside of the case 10 to the outside. In this embodiment, the protruding elastic member 28 is installed on the guide rod 26 corresponding to the rear end of the case 10 with respect to the guide end 33, but may be in an opposite position. Of course, in this case, the direction of action of the elastic force of the elastic member 28 should be reversed.

An opening 36 for a contact is formed by extending from the center portion in the width direction to the rear end of the tray 30. The contact opening 36 allows the first and second contact terminals 22 and 24 to be visible from the upper portion of the tray 30 so that the contact between the card and the contact terminals 22 and 24 can be made. At the same time, it serves to prevent interference with the contact terminals 22 and 24 when the tray 30 moves.

A mounting guide 38 is formed along an edge of the second seating surface 32 of the tray 30. The mounting guide 38 is to hold the edge of the card seated on the second seating surface 32 so as not to flow from the card seating second seating surface. The mounting guide 38 may be made of a metal material having good elasticity. The mounting guide 38 is located in a through hole (not shown) formed in the tray 30.

The movement guide step 39 is formed at a position corresponding to the guide step 20 of the case 10 on the bottom surface of the tray 30. The movement guide step 39 allows the tray 30 to move along a predetermined path while moving along the guide step 20.

Hanging protrusions 40 are formed on the opposite side of the tray 30 from the side of the guide 30. The hook protrusion 40 is interlocked with the interlocking cam 60 to be described below to allow the tray 30 to be in or out of the case 10. The hook protrusion 40 is provided with a hook 41 in the tip direction of the tray 30. The hook surface 41 is formed to be orthogonal to the side surface of the tray 30. The hook surface 41 is hooked to the hook end 64 of the interlocking cam 60 to be described below.

A guide surface 42 is formed to be inclined on the hook protrusion 40 corresponding to the opposite side of the hook surface 41. The guide surface 42 is interlocked with the interlocking cam 60 to be described below, so that the rotation of the interlocking cam 60 occurs smoothly.

The operation lever 50 is rotatably installed on the lever rotation shaft 17 of the case 10. The lever rotation shaft 17 penetrates an intermediate portion of the operation lever 50. The operation lever 50 is made of a metal material, but is not necessarily so. One end of the operation lever 50 protrudes out of the case 10 through the switch opening 16, and the other end extends to a position adjacent to the cam rotation shaft 18.

The coupling part 51 is formed at one end of the operation lever 50. The coupling part 51 extends outside the case 10 through the switch opening 16. The coupling part 51 is provided with an operation switch 52. The operation switch 52 may be integrally formed with the coupling part 51 or made separately. The operation switch 52 is a portion in which a user operates the operation lever 50.

The other end of the operation lever 50 is provided with a pressing portion 54. The pressing part 54 serves to press the hook end 64 of the interlocking cam 60 to be described below. The pressing part 54 is formed to protrude perpendicularly to the other end of the operation lever 50.

A lever elastic member 56 is installed at one end of the other end of the operation lever 50 and one end of an inner surface of the outer wall 11 of the case 10 so as to support both ends. The lever elastic member 56 provides a force to allow the operation lever 50 to rotate counterclockwise with reference to the drawing about the lever rotation shaft 17. In this embodiment, the lever elastic member 56 is a cylindrical coil spring, but is not necessarily so. For example, a torsion spring may be installed on the lever rotation shaft 17 to provide a force to the operation lever 50.

The interlocking cam 60 is rotatably installed on the cam rotation shaft 18. The interlocking cam 60 has a disc shape in which both ends thereof are cut in a plan view, and a guide curved surface 62 is formed along a side outer edge of a predetermined section. The guide curved surface 62 is a curved surface having a predetermined radius of curvature and is in contact with the pressing portion 54 of the operation lever 50 to be described below.

Hook portions 64 are formed at portions where the guide curved surface 62 ends. The hook end 64 is a portion formed by cutting off a part of the interlocking cam 60 and is formed at both end portions of the guide curved surface 62. One end of the hook 64 is selectively in close contact with the hook protrusion 40 of the tray 30, and the other end of the hook 64 is selectively in close contact with the pressing portion 54 of the operating lever 50. That is, in the state in which the tray 30 is inside the case 10, one side hook 64 is in close contact with the hook protrusion 40 of the tray 30, and the other hook end 64 is the manipulation lever. It is in close contact with the pressing part 54 of 50.

The stop surface 66 is formed on the opposite side of the guide curved surface 62 from the interlocking cam 60. When the tray 30 protrudes out of the case 10, the stop surface 66 is in close contact with the side surface of the tray 10 to prevent the interlocking cam 60 from being rotated any further. The stop surface 66 is formed on the opposite side of the guide curved surface 62, but only one side thereof is used.

In the interlocking cam 60, an interference avoiding portion 68 is formed between a portion where the guide curved surface 62 is formed and a portion where the stop surface 66 is formed. The interference avoiding part 68 cuts off both sides of the upper surface of the interlocking cam 60, and avoids interference between the hook protrusion 40 of the tray 30 and the pressing part 54 of the operation lever 50. It plays a role. For reference, the hook end 64 corresponds to one inner surface of the interference avoiding part 68.

Hereinafter, the dual card socket connector according to the present invention having the configuration as described above will be used in detail.

In the dual card socket connector of the present invention, in order to insert a card in the state shown in FIGS. 1 and 2, the tray 30 must protrude out of the case 10 by operating the manipulation switch 52. .

When the operation switch 52 is removed in the front direction of the case 10, the operation lever 50 is rotated in a clockwise direction with reference to FIG. 2 about the lever rotation shaft 17. That is, the lever elastic member 56 is rotated while compressing.

When the operation lever 50 rotates, the pressing portion 54 of the operation lever 50 no longer presses the hook end 64 of the interlocking cam 60. Therefore, the tray 30 starts to move out of the case 10 by the restoring force of the protruding elastic member 28.

When the tray 30 starts to move, the interlocking cam 60 is rotated by the hook protrusion 40. The tray 30 is moved by the restoring force of the protruding elastic member 28 until the guide end 33 is engaged with the mounting end 14 or until the protruding elastic member 28 is completely restored. . 6 shows a state in which the tip of the tray 30 protrudes out of the case 10. Here, the guide end 33 is in close contact with the installation end 14 and no longer moves. Of course, the hook protrusion 40 also hangs on the guide wall 12 on the tip side of the case 10 so that it is no longer moved.

On the other hand, when the tray 30 is moved, the guide end 33 is guided along the guide rod 26 and the movement guide step 39 is also guided along the guide step 20. In this way, the tray 30 is moved in a straight line along the correct path.

As shown in FIG. 6, when the tip of the tray 30 is protruded to the outside of the case 10, the user places a card on the first or second seating surfaces 31 and 32 of the tray 30. Can be seated. A relatively large card is seated on the first seating surface 31, and a relatively small card is seated on the second seating surface 32. Of course, cards may be respectively mounted on these seating surfaces 31 and 32 at the same time. At this time, holding the tip of the card with the thumb and forefinger is to place the card on the seating surface (31, 32) in a state that the finger portion is located in the cutout portion 34 for the handle.

When the front end of the tray 30 is pushed into the case 10 while the card is seated on the seating surfaces 31 and 32, the tray 30 overcomes the elastic force of the protruding elastic member 28. Go inside. At the same time, the interlocking cam 60 whose stop surface 66 is in close contact with the side surface of the tray 30 is rotated by the movement of the tray 30.

At the time of rotation of the interlocking cam 60, the guide curved surface 62 rotates in contact with the pressing portion 54 of the operating lever 50, and the guide curved surface 62 is the pressing portion 54. When no longer in contact with the pressing portion 54 is seated on the hook end (64). This is achieved by the restoring force of the lever elastic member 56.

The interlocking cam 60 is rotated so that one hook end 64 of the interlocking cam 60 is in close contact with the hook 41 of the hook protrusion 40, and the operation lever 50 is attached to the other hook end 64. When the pressing portion 54 is in close contact, the tray 30 is completely inserted into the case 10. This state is the state of FIGS. In this state, the card comes into contact with the first or second contact terminals 22 and 24 to make an electrical connection.

On the other hand, in the state that the card is seated on the second seating surface 32, the mounting guide 38 to hold the edge of the card to maintain the contact state with the second contact terminal 24. Of course, the card seated on the first seating surface 31 is pressed by the shell 10 ′ itself or a configuration provided therein in a state seated on the first seating surface 31, so that the first contact terminal 22 is closed. ) Can be maintained.

On the other hand, the contact opening 36 formed in the tray 30 has the first and second contact terminals 22 and 24 simultaneously on the first and second seating surfaces 31 and 32 of the tray 30. The first contact terminal 22 is in the position corresponding to the first seating surface 31 and the second contact terminal 24 is in the position corresponding to the second seating surface 32. The relatively large card seated on the seating surface 31 and the relatively small card seated on the second seating surface 32 may be brought into contact with the first contact terminal 22 and the second contact terminal 24, respectively. have. That is, cards of different sizes can be used simultaneously.

The scope of the present invention is not limited to the embodiments described above, but may be defined by the scope of the claims, and those skilled in the art may make various modifications and alterations within the scope of the claims It is self-evident.

For example, although the case 10 and the shell 10 'form the appearance of the card socket connector in the illustrated embodiment, this is not necessarily the case. For example, a case consisting of an upper case and a lower case constitutes an appearance and the shell 10 'may or may not be part of the case. The shell 10 'can be regarded as part of the case.

In addition, although the operation lever 50 and the interlocking cam 60 were used for the entry and exit of the tray 30, the tray entry / exit mechanism, which is a configuration for the entry and exit of the tray 30, may be adopted. Can be. For example, a lever that is directly engaged to the hook protrusion 40 of the tray 30 is supported in a direction to be hooked to the hook protrusion 40 by a spring, and the user can support the lever while overcoming the elastic force of the spring. When pulled out, the tray 30 protrudes. On the contrary, when the tray 30 is pushed in, the hooking protrusion 40 retracts the lever, and when the hooking protrusion 40 passes, the hooking protrusion 40 again by the elastic force of the spring. It can also be configured to hang on).

In addition, as another example of the entry / exit mechanism of the tray 30, when one end of the lever moves along the cam groove, once pressed, the inside of the cam groove is pressed, and when pressed again, the structure may be separated from the inside of the cam groove. The cam groove is separated from a path into which the end of the lever enters to be walked, and thus a path when the cam groove exits to guide the end of the lever.
