Description

Cable Connector Assembly

【Technical field】

The invention relates to a cable connector assembly, in particular to a cable connector assembly with a circuit board.

【Background technique】

With the rapid development of electronic products and the increase of equipment functions, the structure of the connector is becoming more and more complex, and the circuit board is gradually integrated into the interior of the connector. The circuit board not only has conductive paths, but also includes chips, capacitors, resistors, etc. Electronic components, but the molding step is often required in the connector manufacturing process, and the high temperature and high pressure conditions of direct molding can easily damage electronic components.

Therefore, it is necessary to improve the cable connector assembly to solve the above problems.

【Content of invention】

The main object of the present invention is to provide a cable connector assembly with an improved structure, which has a structure for protecting electronic components on a circuit board.

In order to achieve the above object, the present invention adopts the following technical solution: a cable connector assembly, which includes an insulating body, a terminal installed in the insulating body, a circuit board electrically connected to the terminal, and a cable connected to the rear end of the circuit board and an insulating shell, the circuit board is provided with electronic components, the cable connector assembly also includes an insulating inner shell assembled on the circuit board and protecting the electronic components, the electronic components are accommodated in the insulating inside the shell.

Compared with the prior art, the invention has the following beneficial effects: the insulating inner shell can protect the electronic components on the circuit board from being damaged.

【Detailed ways】

1 to 6, the cable connector assembly 100 of the present invention includes an insulating body 1, a number of terminals 2 accommodated in the insulating body 1, a metal shell 3 surrounding the insulating body 1, a circuit board 4, Insulate the inner shell 5, the outer shell 6 and the cables 7.

The metal shell 3 includes a first shell 31 and a second shell 32 assembled together. The first shell 31 covers the butt joint at the front end of the insulating body 1, and the second shell 32 covers the mounting portion at the rear end of the insulating body 2. (not marked), a pair of screws 8 pass through the first shell 31 and the second shell 32 to fix them.

The terminal 2 extends backward out of the rear side of the insulating housing 1 and is connected to the front end of the circuit board 4 . The circuit board 4 is trapezoidal and located behind the insulating body 1 and the second housing 32 . The circuit board 4 is provided with an electronic component 41 and a plurality of through holes 42 located around the electronic component 41 . The insulating inner shell 5 includes a main body 51 with a receiving space 511 and several pairs of assembly feet 52 extending downward from the main body 51. The main body 51 has a shape similar to that of the circuit board 4, and each assembly foot 52 is provided with a protrusion 521 Therefore, it can be buckled with the corresponding through hole 42 of the circuit board 4 , so that the electronic component 41 is closed and accommodated in the accommodation space 511 of the insulating inner shell 5 .

The insulating shell 6 is overmolded on the outermost layer, but before forming the insulating shell 6, an inner mold (not shown) must be formed at the tail of the terminal 2, the circuit board 4, the insulating inner shell 5 and the front end of the cable 7, because the insulating inner The protection of the shell 5 prevents the electronic components 41 from being damaged by the inner mold.

The insulating shell 6 covers the second casing 32 , the inner mold, the circuit board 4 , the insulating inner shell 5 and the cable 7 . The insulating inner shell 5 only covers the area where the electronic components 41 are arranged on the circuit board 4 .

In other embodiments, the insulating shell 6 can also be directly overmolded on the outermost layer without forming the inner mold first, or the insulating shell 6 adopts an upper and lower shell structure that is welded together. The molding of the two insulating shells The method will also go through a high-temperature process, and the insulating inner shell 5 will also provide protection for the electronic component 41 .
