After more than half of the length of the body 100 is drawn out of the body 100, the tray 200 is inclined. At this time, the first contact portion C1a of the first card C1 accommodated in the front side of the card holder 200 moves along the card holder 200 at an inclined angle toward the third terminal 156 located on the rear side of the housing 100.

At this time, the front end portion of the first protruding portion 156b-1 of the first connection terminal 156b provided in the third connection terminal 156 does not protrude toward the upper portion thereof than the lower surface of the first contact portion C1a. The first sliding portion 156b-2 of a connection terminal 156b slides along the lower surface of the first contact portion C1a. And, the second protruding portion 156c-1 of the second connection terminal 156c provided in the third connection terminal 156 The front end portion projects toward the upper portion than the lower surface of the first contact portion C1a, so the second sliding portion 156c-2 of the second connection terminal 156c temporarily collides with the outer edge of the first contact portion C1a, that is, the edge portion. At this time, the second sliding portion 156c-2 is formed obliquely so that an end portion thereof can be positioned laterally of the first sliding portion 156b-2. Therefore, the second sliding portion 156c-2 is received by the outer edge of the first contact portion C1a. When the pressure is pressed downward, the first contact portion C1a safely slides along the second sliding portion 156c-2.

Hereinafter, this will be described in more detail, and a hypothetical first line (not shown) and a hypothetical second line (not shown) are formed, and the first line is formed in parallel along the lower surface of the first contact portion C1a; The second line is formed at an angle of 45 ° to the first line on the outer edge of the lower surface of the first contact portion C1a that meets the second sliding portion 156c-2. And, when the outer edge of the first contact portion C1a of the first card C1 moving along the card holder 200 is caught on the third terminal 156, the first sliding portion 156b-2 is formed obliquely so as to be located on the first line and the first Between the two lines, the second sliding portion 156c-2 is formed obliquely, and is located more inclined than the first sliding portion between the first line and the second line. As a result, the first sliding portion 156b-2 and the second sliding portion 156c-2 both collide with the outer edge of the first contact portion C1a at an angle of less than 45 °. Therefore, the first contact portion C1a is pressed downward by the first The state of the sliding portion 156b-2 and the second sliding portion 156c-2 is a sliding movement.

In this way, in the process of detaching the card holder 200 inserted into the housing 100 to the outside, the present invention will not contact the contact portion of the card accommodated in the card holder 200 even if the card holder 200 is tilted and moved. Since the three connection terminals 156 are stuck, the shape of the third connection terminal 156 is not changed, and there is an effect that a poor contact does not occur.

In addition, as described above, since the interval between the side of the tray 200 and the housing 100 is relatively narrow, when the tray 200 starts to be pulled out, the tray 200 is not tilted and is drawn straight along the length direction of the housing 100. At this time, the first contact portion C1a of the first card C1 accommodated in the front side of the tray 200 is not located in the housing. The first terminal 152 on the front side of 100 is stuck and easily moves in the direction of the third terminal 156. Here, the formation of the first connection terminal 152 is similar to that of the second terminal 14 (shown in FIG. 2) provided in the conventional socket 10 (shown in FIG. 2). The first connection terminal 152 ′ (shown in FIG. 12) is distinguished, and the first connection terminal 152 is defined as an ordinary terminal.

FIG. 12 is a schematic view showing a first contact of a first terminal 152 ′ of a connector device having a terminal jam prevention function for explaining a preferred embodiment of the present invention and a first card received in a tray 200; Diagram of the state of the collision.

Referring to FIG. 12, according to circumstances, the interval between the side of the Cato 200 and the casing 100 is relatively wide. When the Cato 200 is pulled out of the casing 100, the Cato 200 may be drawn out from the beginning when it is pulled out. . At this time, the first contact portion C1a of the first card C1 accommodated in the front side of the tray 200 is moved along the tray 200 at an inclined angle toward the first terminal 152 'located on the front side of the housing 100, and is connected to the first wiring The terminal 152 'collided.

At this time, the formation of the first connection terminal 152 'is the same as that of the third connection terminal 156, so detailed description of the shape of the first connection terminal 152' is omitted. Such a first connection terminal 152 ′ has a first connection terminal 152 b ′ and a second connection terminal 152 c ′ formed on one side of the connection portion 152 a ′, and the first projection portion 152 b-1 of the first connection terminal 156 b ′ is formed. Since the front end portion of the first contact portion C1a does not protrude toward the upper portion thereof, the first sliding portion 152b-2 'of the first connection terminal 152b' slides along the lower surface of the first contact portion C1a. In addition, since the front end portion of the second protruding portion 152c-1 'of the second connection terminal 152c' protrudes toward the upper portion than the lower surface of the first contact portion C1a, the second sliding portion of the second connection terminal 152c ' 152c-2 'collides with the outer edge of the first contact portion C1a, that is, the edge portion. At this time, the second sliding portion 152c-2 'is formed obliquely so that its end portion, that is, the second end portion 152c-3' is located to the side of the first sliding portion 152b-2 ', because This second sliding portion 152c-2 'is pressed downward by the pressure of the outer edge of the first contact portion C1a. As a result, the first contact portion C1a safely slides along the second sliding portion 156c-2'.

Although the present invention has been described in detail through examples, the present invention is not limited to this. Many variations and modifications can be made within the scope of the technical idea of the present invention, which is obvious to those skilled in the art to which the art belongs. If such deformation and modification belong to the scope of the claims, the technical idea should also be It is considered to belong to this invention.
