Description

  The present invention relates to a connector assembly, and more particularly to a connector assembly that transmits an audio signal or a video signal.

  A connector assembly according to the prior art includes an insulating main body, a terminal formed by insert molding on the insulating main body, a closing member, and a metal member. An insertion hole is formed in the terminal. The closing member includes an insertion portion that is inserted into the insertion hole of the terminal, and a closing portion that abuts on a rear edge portion of the insertion hole. When the insulating body is manufactured by insert molding with an insulating material using the terminal and the closing member as an insert product, the insulating material is blocked by the closing portion and does not flow into the insertion hole of the terminal.

China Utility Model No. 201408321U Specification

  Since the closing portion of the closing member is made of the insulating material, it is easily damaged during the manufacturing process. As a result, the damaged closed portion cannot stably close the terminal.

  SUMMARY OF THE INVENTION In view of the above-described problems of the prior art, an object of the present invention is to provide a connector assembly that stably closes terminals.

  In order to achieve the above object, a connector assembly of the present invention includes an insulating main body, a metal member, a terminal, and a closing member. The metal member is fixed to the insulating main body and provided with a connection portion. The terminal is formed on a first end protruding from the insulating body, a second end fixed to the insulating body and having an end face, an insertion hole, and an end face of the second end, and the insertion An opening communicating with the hole. The closing member includes an insertion portion that is inserted into the insertion hole of the terminal from the opening side, and a closing portion that comes into contact with the end surface of the second end. A space is formed on the rear side in the insertion direction of the end face of the blocking portion. At least a portion of the end surface of the blocking portion is exposed in the space. The insulating main body is molded by insert molding using the terminal, the closing member, the metal member, and an insert mold as inserts. The space is formed by removing the insert mold.

  Compared with the prior art, the present invention has the following advantages. A space is formed on the rear side of the closed portion. That is, in the process of insert molding, the blocking portion is protected by the insert mold and is not easily damaged by the insulating material. By using the insert mold, the blocking portion is protected. At the same time, the insulating material does not flow into the insertion hole of the terminal due to the blocking of the blocking portion of the blocking member. Thereby, the terminal is stably closed.

It is sectional drawing of another embodiment cut | disconnected along the AA line of FIG.

  Referring to FIGS. 1 and 2, the connector assembly of the present invention includes a main body 100, a protective member 200 that protects the main body 100, and a cable 300 that is connected to the main body 100.

  As shown in FIG. 3, the main body 100 includes an insulating main body 1, a tubular terminal 2 formed by pultrusion molding, a metal member 3, and a closing member 4. The terminal 2 includes a first end 21, a second end 22, and an annular rib 23 that protrudes radially outward. As shown in FIG. 5, an insertion hole 20 is formed in the terminal 2. An opening 24 penetrating the insertion hole 20 is formed at the second end 22 of the terminal 2.

  As shown in FIGS. 3 and 5, the closing member 4 includes a closing portion 42 having an end surface 420 and an insertion portion 41 protruding forward from the closing contact portion 42.

  As shown in FIG. 3, the metal member 3 includes a cylindrical portion 31 and a solder connection portion 32 extending rearward from the cylindrical portion 31.

  3 to 6, when the main body 100 is manufactured, the insertion portion 41 of the closing member 4 is inserted into the insertion hole 20 of the second end portion 22 of the terminal 2. The closing contact portion 42 of the closing member 4 is not inserted into the insertion hole 20 of the terminal 2 and contacts the second end portion 22 to close the opening 24. The terminal 2, the closing member 4 and the metal member 3 are fixed to a mold for molding the insulating main body 1. At this time, an insert mold is disposed at the rear end of the closing member 4. An insulating material is injected into a mold in which the terminal 2, the closing member 4 and the metal member 3 are fixed, and insert molding is performed, whereby the insulating body 1 is manufactured.

  As shown in FIGS. 3 and 4, the insulating main body 1 includes a first slot 101, a second slot 102, a first recess 103 communicating with the first slot 101, and the second slot 102. A second recess 104 communicating with the second recess 104 is formed. The second end 22 of the terminal 2 is fixed to the insulating body 1. A first end 21 of the terminal 2 protrudes from the insulating body 1. The solder connection portion 32 of the metal member 3 is exposed in the first recess 103. The second end 22 of the terminal 2 is partially exposed in the second recess 104 (not shown).

  After the insert molding, the insert mold is removed. 6 and 7, the insulating body 1 is formed with a space 106 that extends along the lateral direction perpendicular to the front-rear direction and penetrates the insulating body 1. When an insert mold having a width larger than the diameter of the end face 420 of the closing contact portion 42 of the closing member 4 is used, a small space 106 is formed in the middle portion of the closing portion 42 as shown in FIG. That is, in the process of insert molding, the intermediate portion of the closing portion 42 is protected by the insert mold and is not easily damaged by the insulating material. When an insert mold having the same width as the diameter of the end surface 420 of the closing portion 42 of the closing member 4 is used, a large space 106 is formed in the closing portion 42 as shown in FIG. That is, in the process of insert molding, the closing portion 42 is all protected by the insert mold and is not easily damaged by the insulating material.

  As shown in FIG. 2, the cable 300 includes a first line 301 and a second line 302. The first wire 301 is inserted into the first slot 101 and soldered to the solder connection portion 32 of the metal member 3. The second line 302 is inserted into the second slot 102 and soldered to the second end 22 of the terminal 2.

  As shown in FIG. 1, the protective member 200 covers the insulating body 1.

  By using the insert mold, the blocking portion 42 is protected. The insulating material does not flow into the insertion hole 20 of the terminal 2 by being blocked by the blocking portion 42 of the blocking member 4. The length of the insertion portion 41 of the closing member 4 is shorter than the length of the insertion hole 20, and the insertion portion 41 does not reach the front end of the first end 21 of the terminal 2. Thereby, the terminal 2 can be deformed when subjected to a lateral force and is not easily damaged. The ribs 23 of the terminal 2 are firmly engaged with the insulating main body 1.

  As mentioned above, although this invention was demonstrated in detail with reference to preferable embodiment, embodiment is an illustration to the last and is not limited to these. In the above description, any modification or change of details that can be made based on the present invention belongs to the technical scope of the present invention.
