As illustrated in FIG. 7, the jack contact terminal 300b according to the embodiment of the present invention is caught on the outer circumferential surface to prevent the plug contact terminal 300a from being separated from each other in a direction away from each other in the process of being inserted into the jack contact terminal 300b. The protrusion 320 is formed, and the locking groove 410 is formed on the inner circumferential surface of the jack insulator 400b surrounding the outer circumferential surface of the jack contact terminal 300b to engage the locking protrusion 320 as shown in FIG. 8.

Therefore, in the process of inserting the plug module 10a into the jack module 10b so that the plug contact terminal 300a contacts and inserts into the jack contact terminal 300b, the plug contact terminal 300a and the jack contact terminal ( 300b) is prevented from escaping in a direction away from each other.

For example, in the process of inserting the plug contact terminal 300a into the jack contact terminal 300b, the jack contact terminal 300b is inserted in the direction in which the plug contact terminal 300a is inserted by friction with the plug contact terminal 300a. The slip may be pushed out of the normal position, and the locking protrusion 320 is formed on the outer circumferential surface of the jack contact terminal 300b, thereby preventing such movement.

The locking protrusion 320 may be formed only on the jack contact terminal 300b, but may also be formed on the outer surface of the plug contact terminal 300a. In this case, the locking groove 410 may also be formed on the plug insulator 400a. Can be formed.

On the other hand, the jack guide shell 200b may be formed with a pressing protrusion 240 on the inner circumferential surface of the jack insulator 400b to prevent the jack insulator 400b from being separated from the plug insulator 400a in a direction away from each other. Of course, the pressing protrusion 240 may be formed on the inner circumferential surface of the plug guide shell 200a in addition to the jack guide shell 200b.

Meanwhile, as illustrated in FIGS. 6A and 6B, the jack guide shell 200b includes an elastic holding part 220 which is cut in a plurality in the circumferential direction at an end portion facing the plug guide shell 200a. The elastic retainer 220 is formed to elastically press the outer circumferential surface of the plug guide shell 200a in a state where the plug guide shell 200a is inserted.

According to this structure, since the elastic retaining portion 220 of the jack guide shell 200b elastically presses the outer circumferential surface of the plug guide shell 200a while the plug guide shell 200a is inserted into the jack guide shell 200b, Cohesion between each other is improved to maintain a more stable bonding state.

At this time, the elastic retaining portion 220 may be formed in a separate pipe shape that is inserted into the end portion of the jack guide shell 200b, as shown in Figure 6 (b), the middle portion is concave in the radial direction It is formed to be curved so that it can be configured to elastically press the outer peripheral surface of the plug guide shell (200a).

In addition, the elastic retaining unit 220 may be formed in a shape that is cut so that the jack guide shell 200b is opened in the end direction as shown in (a) of FIG. 6, in this case, the jack guide shell 200b A separate elastic fixing ring 230 is coupled to surround the outer circumferential surface of the elastic holding part 220, and the elastic fixing ring 230 may be formed in a “C” shaped ring shape with one side open. The elastic fixing ring 230 is preferably formed of an elastic material, and serves to additionally generate an elastic force by supplementing the structural elastic retainer 220 having a "C" shape. In addition, even if the elastic force is reduced in the elastic retaining portion 220 due to long time use, the elastic fixing ring 230 to compensate for this to continue to exhibit the elastic force, accordingly the plug guide shell (200a) and jack guide shell (200b) Cohesion with can be maintained good.

On the other hand, the jack contact terminal 300b is formed with a plurality of elastic coupling portion 330 is cut along the circumferential direction at the end toward the plug contact terminal 300a, as shown in Figure 7, the elastic coupling portion 330 ) Is formed to elastically press the outer circumferential surface of the plug contact terminal 300a in a state where the plug contact terminal 300a is inserted.

Accordingly, since the elastic coupling portion 330 of the jack contact terminal 300b elastically presses the outer circumferential surface of the plug contact terminal 300a while the plug contact terminal 300a is inserted into the jack contact terminal 300b, Cohesion is enhanced to maintain more stable contact coupling and electrical connections.
