Plug connector of printed circuit board

Technical Field

The utility model relates to the technical field of circuit boards, in particular to a plug connector of a printed circuit board.

Background

The plug connector is also called a flat cable plug, i.e. a flexible circuit board, and is used for data transmission in movable parts and movable areas according to flat cable rules, line sequences, line colors, line numbers and the like specified by the industry specifications, for example, a computer internal mainboard is connected with data lines of a hard disk and a CD driver, a mobile phone mainboard is connected with data lines of a display screen, and data lines between connecting devices are collectively called flat cables.

In the use process of the existing flexible circuit board, the plug and the connecting part are detachably fixed in an inserting mode, and frequent inserting and drawing are usually needed, so that the existing flexible circuit board is not only troublesome, but also easily damages the plug; when the plug is inserted into the connecting part, the plug can be inserted reversely, so that the normal use of the circuit board is influenced, a short circuit can be caused, and the circuit board is damaged.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects that the conventional connector is frequently plugged and damaged, the utility model provides the plug connector of the printed circuit board, which solves the problem by arranging a rebounder between a connecting seat and a plug.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a plug connector of printed circuit board, which comprises a connecting seat, plug and winding displacement, the connecting seat includes shell and the public end of pegging graft, be equipped with two rows of public ends of pegging graft in the shell, the plug includes the fixed block, female end of pegging graft and winding displacement hole, the winding displacement hole has been seted up on the fixed block, the fixed block bottom is equipped with two rows of female ends of pegging graft, the public end of pegging graft stretches into the female end of pegging graft, make the fixed block arrange the shell in, the winding displacement pressure equipment is downthehole in the winding displacement, be equipped with on the face of connecting of shell and fixed block and press the popup device, press the popup device including setting up the bounce-off ware in the shell and the trigger shell fragment that sets up in the fixed block bottom surface, trigger the shell fragment and lean on at the bounce-off ware top.

Furthermore, the pressing and popping device is provided with two groups which are symmetrically arranged at two sides of the plug-in male end.

Furthermore, a baffle plate used for resisting the fixing block is arranged in the shell, and the upper surface of the baffle plate is flush with the top end of the rebounder.

Furthermore, an error correction assembly used for guiding and limiting the fixing block is arranged between the shell and the fixing block.

Furthermore, the error correction assembly comprises a rib arranged on the inner wall of the shell and a groove correspondingly arranged outside the fixing block, and the groove is longitudinally spliced with the rib.

Furthermore, the grooves and the convex edges are correspondingly arranged into semi-cylinders or quadrangular columns.

The beneficial effect of the utility model is that,

(1) the rebounder arranged in the shell is pressed to be locked, and then is pressed to be unlocked and popped out, so that the trouble of plugging and unplugging is saved, the plug is prevented from being damaged, and the service life of the connector is prolonged;

(2) through the two groups of pressing ejection devices symmetrically arranged in the shell, the stability of plug connection is ensured, the plug is prevented from falling off, and the normal use of the circuit board is ensured;

(3) through the error correction subassembly that sets up in the shell, lead and spacing to the grafting direction and the inserted position of plug, guarantee to peg graft accurately, improve the availability factor.
