The receptacle connector 13 includes an insulating body 14 , a center contact 15 protruding from the center of the insulating body 14 , and an external conductor 17 formed in a cylindrical shape on the insulating body 14 . . Then, when the external conductor 17 is inserted into the annular space 12 of the plug connector 2, the contact 3 and the center contact 15 are electrically connected. And when the cylindrical external conductor 17 of the receptacle connector 13 is inserted into the annular space 12 of the plug connector 2, the contact portion 6c of the free end is closed by the elasticity of the spring piece 6b. It is fitted to the outer surface of the cylindrical outer conductor 17 of the receptacle 13 .

However, since the shape of the spring piece 6b is complicated, there is a problem in that the manufacturing cost is increased. In addition, there is no separate structure for guiding the position of the contact 3 embedded in the insulating body 4, so the position of the contact 3 is assembled in a state deviated from the fixed position during the assembly process, and the defect rate of the product is increased. There is this. In addition, there is no configuration to separately shield between the contact 3 and the center contact 15 , so there is a problem in that signal interference occurs between the contact 3 and the center contact 15 .

To this end, the present invention places the extension terminal 244 and the contact terminal 242 in the mold while the carrier connection part C1 of the carrier C connected to the extension terminal 244 of the receptacle terminal 240 moves in the mold direction. . After that, the mold is injected into the mold to form the coupling cover 220 . At this time, since the coupling cover 220 is provided with a concave portion 222 , the extension terminal 244 is exposed in the concave portion 222 direction. In this state, the carrier connection portion (C1) of the carrier (C) connected to the extension terminal (244) located in the concave portion (222) is cut at the extension terminal (244), the carrier (C) is removed. Since the coupling cover 220 is provided with the concave portion 222 , the coupling cover 220 and the receptacle terminal 240 have an effect that can be easily insert injection-molded.

On the other hand, in an embodiment of the present invention, the coupling cover 220 and the receptacle terminal 240 are configured to be insert injection-molded, but this is only an embodiment, and in some cases, when the mold is injected into the mold, the coupling cover 220 ) and the receptacle body 210 may be integrally formed. In addition, the coupling cover 220, the receptacle body 210, and the receptacle terminal 240 may all be fitted in a prefabricated manner.

12 is a diagram schematically illustrating a process in which a mating shield is coupled to an extension of a receptacle connector of a connector device including a plug connector and a receptacle connector according to a preferred embodiment of the present invention.

First, referring to FIG. 12 (a), the coupling cover 220 is positioned to be inserted into the receptacle coupling part 212 through insert injection, etc., and the contact terminal 242 is positioned so that the coupling cover 220 passes through. do.

Then, referring to (b) of FIG. 12 , the coupling shield 230 is coupled to the coupling groove 214a of the extension part 214 in a state in which it is inserted. The coupling shield 230 is formed to fill the coupling groove 214a, and may be formed of a material capable of shielding electromagnetic waves.

Then, referring to FIG. 12( c ), a boundary line between both sides of the coupling groove 214a and both sides of the coupling shield 230 is pressed so that the pressing portion P is formed. That is, when the boundary line between both sides of the coupling groove 214a and both sides of the coupling shield 230 is physically pressed, the pressed portion is concavely pressed to form a pressing portion P, and the coupling groove 214a and the coupling shield ( 230) are coupled with each other. As described above, since the present invention is configured to couple the coupling groove 214a and the coupling shield 230 using the pressing part P, the coupling shield 230 can be coupled to the coupling groove 214a with a simple structure. there is

In addition, since the receptacle body 210 and the mating shield are made of a shieldable material, signal interference occurs between the receptacle terminal 240 guided to the receptacle coupling part 212 of the receptacle body 210 and the plug terminal 130 . It has the effect of blocking it from happening.

Fig. 13 is a diagram schematically showing a receptacle connector of a connector device including a plug connector and a receptacle connector according to a preferred embodiment of the present invention, and Fig. 14 is a view showing a plug connector and a receptacle connector according to a preferred embodiment of the present invention It is a diagram showing a receptacle connector of a connector device in cross section.

Referring to the drawings, in order to couple the plug connector 100 and the receptacle connector 200 to each other, the receptacle coupling part 212 is inserted into the plug coupling part 114 . Then, the contact terminal 242 of the receptacle terminal 240 is positioned between the side wall terminal 132 of the plug terminal 130 and the end wall terminal 134 . At this time, the outer periphery of the contact terminal 242 is in contact with the side wall terminal 132 and the end wall terminal 134 , and the plug terminal 130 and the receptacle terminal 240 are electrically connected.

On the other hand, the body coupling guide part 114c is convexly formed on the inner periphery of the plug coupling part 114, and on the outer periphery of the receptacle coupling part 212, the body fitting part ( 212a) is concave. Accordingly, when the receptacle coupling part 212 is inserted into the plug coupling part 114, the body coupling guide part 114c and the body fitting part 212a are mutually fitted, and the receptacle coupling part 212 and the plug coupling part ( 114) has the effect of being strongly coupled to each other. In addition, since the receptacle coupling part 212 and the plug coupling part 114 are firmly coupled to each other, the plug terminal 130 and the receptacle terminal 240 have an effect of stably maintaining an electrically connected state without connection failure.

Although the present invention has been described in detail in the above examples, it goes without saying that the present invention is not limited thereto, and it is apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical spirit of the present invention, and these variations and modifications are appended If it falls within the scope of the claims, the technical idea should also be regarded as belonging to the present invention.
