Background

With the popularization of electronic products, electronic connectors are increasingly used, and the TYPE-C interface is increasingly used due to the unified trend of communication protocols and interfaces. Especially, the TYPE-C interface is used in a large area on the handheld terminal, and meanwhile, the requirements of the lightweight and thin handheld terminal are very strict. For electronic component's overall arrangement, the TYPE-C interface on the current handheld terminal sets up on the interface board generally, and the interface board area is less, consequently the interface board produces through the makeup mode and cuts it again after the welding of TYPE-C interface. Sundries easily appear in the whole production process to enter the TYPE-C interface to cause the damage of the TYPE-C interface, so that in order to solve the problem, the TYPE-C interface is plugged by the plug, and the plug is pulled out after welding is finished. The existing automatic plug-out mode adopts clamping jaws to clamp to a TYPE-C interface shell and then pulls out the plug in the plug-out direction. Because TYPE-C interface is small, the outer contour of the plug is little different than the outer contour dimension of TYPE-C interface, and then in order to guarantee the extraction of the plug, the clamping force of clamping jaw is great usually, very easily leads to TYPE-C interface damage, and clamping jaw and plug relative position are difficult to control simultaneously, and the clamping jaw needs to be far away from the plug before extracting the plug usually, consequently leads to the clamping jaw to produce stronger impact before contacting with plug edge, and then leads to the damage of the plug, extraction failure.
