At the same time, it is convenient to solder the terminal and the cable, and the separator needs to be opened by a separate mold, which increases the manufacturing cost of the cable connector assembly.

Therefore, it is necessary to provide a cable connector combination to solve the aforementioned drawbacks.

It is an object of the present invention to provide a cable connector assembly that is simple in construction and low in cost.

To achieve the foregoing objective, the present invention adopts the following technical solution: a cable connector group The device includes an insulative housing, a conductive terminal received in the insulative housing, a printed circuit board, a plurality of cables, and a housing. The insulative housing includes an abutting portion extending in the front-rear direction and a fixing portion extending rearward from the rear of the mating portion, wherein the terminal receives In the abutting portion, and having a tail portion exposed to the fixing portion, the printed circuit board is fixed to the fixing portion and perpendicular to the extending direction of the mating portion, and the extending direction of the cable is perpendicular to the extending direction of the mating portion, and the printed circuit board is electrically connected to the conductive portion. Terminals and cables.

Compared with the prior art, the cable connector assembly of the present invention can save the cost of separately manufacturing the spacer by using the printed circuit board as the spacer, and the receiving hole of the printed circuit board can be increased between the conductive terminal and the conductive terminal. The insertion and extraction force facilitates welding and simplifies the production process.

Referring to the first to fifth figures, the cable connector assembly 100 includes an insulative housing 1, a conductive terminal 2 mounted on the insulative housing 1, a printed circuit board 3 fixed to the side of the insulative housing 1, a cable assembly 4, and a housing. 5.

The insulative housing 1 includes an integrally formed abutting portion 10 and a fixing portion 11. The mating portion 10 includes an abutting cavity 101 and a terminal slot 102. The docking cavity 101 has an "L" shape and a lateral length greater than a longitudinal length, and the terminal slot 102 is located in the docking cavity. 101 at the bottom right, and horizontally lined up The docking cavity 101 and the terminal slot 102 both extend in the mating direction. The abutting portion 10 extends rearwardly from the fixing portion 11. The fixing portion 11 is provided with a symmetrically disposed projection 110, and a plurality of hooks 111 extend from the rear wall of the fixing block 11.

The conductive terminal 2 includes a contact portion 21, a connecting portion 22, and a tail portion 23. The contact portion 21 and the connecting portion 22 are received in the terminal slot 102.

The printed circuit board 3 has a "convex" shape as a whole, and includes a base portion 31 and an extending portion 32. The lateral length of the extending portion 32 is greater than the lateral length of the base portion 31. The base portion 31 is provided with a plurality of receiving holes 310, and the receiving holes 310 are lined up. And corresponding to the terminal slot 102, the tail portion 23 of the conductive terminal 2 passes through and is electrically connected to the receiving hole 310, the base portion 31 is fixed to the inside of the hook 111, thereby fixing the printed circuit board 3 to the front and rear; at the base portion 31 and the extension portion A recess 33 is formed between the recesses 33, and the recessed portion 33 and the bump 110 are interference-fitted to fix the printed circuit board 3 up and down. The extension portion 32 is provided with a plurality of finger pads 320. The finger pads 320 are arranged in a line. The finger pads 320 are electrically connected to the receiving holes 310 of the base portion 31 by conductive lines on the printed circuit board 3.

The cable assembly 4 is composed of a plurality of cables including an inner core wire 41 and an outer insulating layer 42, and the inner core wire 41 is soldered to the finger pads 320 of the printed circuit board 3.
