Chinese Patent Application Publication No. CN101118998A discloses a cable connector assembly, which includes: an insulating body, a number of conductive terminals, cables, partitions, covers and pull straps, and the partition is located at the connection between the conductive terminals and the cables. The cover body wraps the above-mentioned separator through the outer mold coating method and is partially formed on the rear part of the insulating body and the front end of the cable. The separator is mainly used to seal the gap between the terminal tail and the insulating body to prevent the outer mold from overflowing during molding. Insulation body, and at the same time facilitates the welding of terminals and cables, while the separator needs to be produced in a separate mold, which increases the manufacturing cost of the cable connector assembly.

Therefore, it is necessary to improve the existing technology to overcome the above-mentioned defects.

【Content of invention】

The main purpose of the present invention is to provide a cable connector assembly with simple structure and low cost.

In order to solve the above technical problems, the present invention provides a cable connector assembly, which includes an insulating body, conductive terminals accommodated in the insulating body, a printed circuit board, several cables and a housing, the insulating body includes An extended docking portion and a fixing portion extending backward from the rear of the docking portion, wherein the terminal is accommodated in the docking portion and has a tail exposed in the fixing portion, the printed circuit board is fixed to the fixing portion and extends from the docking portion The direction is vertical, the extension direction of the cable is perpendicular to the extension direction of the docking part, and the printed circuit board is electrically connected to the conductive terminal and the cable.

Compared with the prior art, the present invention has the following beneficial effects: due to the use of printed circuit boards as partitions, not only can the cost of making separate partitions be saved, but also the receiving holes on the printed circuit board can increase the distance between them and the conductive terminals. Insertion force, convenient welding, simplifying the production process.

【Detailed ways】

Please refer to Fig. 1 to Fig. 5, which is a cable connector assembly 100 of the present invention, which includes an insulating body 1, a conductive terminal 2 installed in the insulating body 1, a printed circuit board 3 fixed on one side of the insulating body 1, a wire Cable combination 4 and housing 5.

The insulating body 1 includes a docking part 10 and a fixing part 11 integrally formed. The docking part 10 includes a docking cavity 101 and a terminal slot 102. The docking cavity 101 is in the shape of an "L" and its transverse length is greater than its longitudinal length. The terminal slot 102 is located in the docking cavity 101 on the lower right, and lined up in a horizontal direction, the docking cavity 101 and the terminal slot 102 both extend along the docking direction. The docking portion 10 extends rearwardly out of a fixing portion 11 , and the fixing portion 11 is provided with symmetrically arranged protrusions 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 connection portion 22 and a tail portion 23 , and the contact portion 21 and the connection portion 22 are accommodated in the terminal slot 102 .

The printed circuit board 3 is in a "convex" shape as a whole, and includes a base 31 and an extension 32. The lateral length of the extension 32 is greater than that of the base 31. The base 31 is provided with a number of receiving holes 310, and the receiving holes 310 are arranged in a row. And communicate with the terminal slot 102 correspondingly, the tail portion 23 of the conductive terminal 2 passes through and electrically connects the receiving hole 310, the base portion 31 is fixed on the inside of the hook 111, thereby fixing the printed circuit board 3 front and rear; between the base portion 31 and the extension portion 32 forms a recessed portion 33, and the recessed portion 33 interferes with the protrusion 110 to fix the printed circuit board 3 up and down. The extension portion 32 is provided with a plurality of finger pads 320 arranged in a row. The finger pads 320 are electrically connected to the receiving holes 310 of the base 31 through the conductive lines on the printed circuit board 3 .

The cable assembly 4 is composed of several cables. The cables include an inner core wire 41 and an outer insulating layer 42 . The inner core wire 41 is welded to the finger soldering point 320 of the printed circuit board 3 .
