The beneficial effect of above-mentioned structure is: the contact pin subassembly adopts the modular structure design, thereby be convenient for the assembly of contact pin subassembly and casing, and the clamp plate of upper cover can compress tightly the contact pin subassembly in the base, thereby can guarantee that the connection of contact pin subassembly and casing is compacter, the contact pin is difficult not hard up, drop, and cover on and be provided with the line ball bolt that is used for compressing tightly the wire, but line ball bolt locking wire, after the wire received the pulling force, the wire can not take off with the contact pin pine, can guarantee that the wire is connected more reliably with the electricity of contact pin. Therefore, the plug has the advantages of simple structure, stable and reliable performance and convenience in assembly.
Particularly, a clamping plate is arranged at one end of the base, a clamping groove matched with the clamping plate is formed in a wire hole of the upper cover, the clamping plate is inserted into the clamping groove and forms limit fit of the upper cover and the base, a clamping hole is formed in the other end of the base, a clamping block matched with the clamping hole is arranged at the other end of the upper cover, and the clamping block is clamped in the clamping hole and forms clamping fit of the upper cover and the base. The two ends of the upper cover are respectively clamped on the base, so that the upper cover and the base are assembled conveniently, the assembly of the base and the upper cover is improved, and the base and the upper cover can be connected more compactly.
Particularly, a positioning sleeve is arranged in the base, a positioning hole is formed in the needle base, the positioning sleeve is inserted in the positioning hole to form limiting fit of the positioning sleeve and the needle base, and the screw penetrates through the positioning sleeve and is connected to the upper cover. The needle seat is clamped on the positioning sleeve in the base, so that the base and the needle seat can be assembled conveniently, and the assembly is more convenient.
Particularly, the base in correspond the both sides punishment of needle file do not be provided with the sand grip, the sand grip contradict respectively on the both sides of needle file, and constitute the spacing cooperation of sand grip and needle file. The raised lines in the base can compress the needle base, so that the connection between the base and the needle base can be more compact, and the working reliability of the plug can be improved.
