Socket connector and ball locking structure

Abstract

The invention relates to a socket connector and a ball locking structure. The socket connector includes a socket shell; the socket shell includes a cylindrical plugging end; the side wall of the cylindrical plugging end is provided with installation holes which are in radial penetrating; balls are installed in the installation holes; the edge on the one end of each installation hole is provided with a closing-in structure which can prevent the balls from separating from the end; the installation holes are provided with anti-stripping rings which can be put in the other ends of the installationholes to surround the surfaces of the balls; the socket shell is provided with an anti-stripping structure which can prevent the anti-stripping rings from separating from the installation holes; andthe ends of the anti-stripping rings away from the closing-in ends of the installation holes are provided with introversive edges which can prevent the balls from separating. The installation structure can stop the balls in the installation holes to make the balls float in a radial direction in the installation holes so that the balls cannot be separated from the installation holes, and can eliminate damages to the surfaces of the balls caused by rivet turning processes in a rivet pressing technology.

Description

technical field [0001] The invention relates to a socket connector and its ball locking structure. Background technique [0002] In the existing push-pull connectors, the plug and the socket are generally locked by a ball locking structure, and its structure is generally as follows figure 1 As shown, including the socket 1 and the plug 2, the front end of the socket housing is provided with a mounting hole, the mounting hole is provided with a ball 12 that can radially float in the mounting hole but will not come out, and the outer wall of the plug inner shell 21 An arc-shaped groove matching the ball 12 is provided. When the socket 1 and the plug 2 are mated, when the ball 12 moves to the position corresponding to the arc-shaped groove, the ball 12 is locked by the lock set on the inner shell 21 of the plug. The tight sleeve 22 is pushed into the arc-shaped groove on the inner shell of the plug so as to realize the locking between the plug 2 and the socket 1 . [0003] In...

Problems solved by technology

The problem in the actual operation of this method is that during the manufacturing process of the socket connector, the balls must be electroplated to enhance the surface effect and surface smoothness of the balls, because the riveting process is likely to cause damage to the balls 12, which leads to The order of riveting and electroplating will cause defects on the surface of the ball 12. For example, when the method of electroplating first and then riveting is used, the electroplating surface of the ball 12 will be scratched, which will affect the appearance of the ball 12; the method of riveting first and then electroplating At this time, because the ball 12 has been damaged, the surface of the ball 12 will be stained and uneven during the subsequent electroplating, which not only affects the appearance of the ball 12, but also increases the friction force when the ball 12 rotates, causing the plug 2 and the socket 1 to be pushed and pulled tightly when they are plugged in. astringent, not smooth
