Description

Wire stop structure for wire rod Technical Field The present disclosure relates to wire guides, and particularly to a wire guide structure with conductive function. Background With rapid development of technology, electronic devices, such as audio/video playing devices or electronic parts in computers, such as integrated circuits, usually default a grounding circuit on a motherboard, and the grounding circuit is coupled to a grounding wire in a power wire so as to conduct and guide a leakage current to the ground for release, so as to avoid injury to a human body when leakage occurs. In addition, the electronic equipment has poor insulating property or moist use environment, so that the shell of the electronic equipment has certain static electricity, and electric shock accidents can occur in serious cases. Particularly, when the housing of the electronic device is made of a metal material, the metal housing cannot be connected with the grounding wire in the power wire, so that static electricity on the metal housing cannot be conducted and discharged, and therefore, the static electricity often causes electric shock injury to personnel, which is needed to be improved. Disclosure of Invention The invention mainly aims to provide a wire stop structure for a wire, which can be connected to a metal shell so as to lead out and release static electricity accumulated in the metal shell through a power wire combined with the wire stop structure and provided with a grounding wire, thereby avoiding electric shock injury to personnel. The wire stop structure for wire rod includes one metal fixing pipe with front end with through hole for the power wire to pass through, one fixing mechanism for the power wire to pass through, one sleeve hole connected to the through hole and with relatively large hole diameter, one first joint part in the back end, one metal pipe spring with front section set inside the sleeve hole and with slot in the outer peripheral surface, at least two anti-back wings extending forwards and around the slot for the power wire to pass through, one metal net layer connected to the power wire, one positioning hole for the power wire to pass through, and one tightening pipe with the back end of the positioning hole and with the second joint part. In one embodiment, the rear section of the tube spring forms a first tapered section tapering backward and the first tapered section is adjacent to the binding opening section, and the rear sections of the tightening tube and the positioning hole form a second tapered section tapering backward and a tapered inner wall respectively corresponding to the first tapered section, and the tapered inner wall forms a tightening effect on the first tapered section to enable the binding opening section to tighten and fix the plastic sheath of the power wire. In one embodiment, the fixing mechanism comprises a collar and a ring groove radially adjacent to each other on the outer peripheral surface of the front end of the fixing tube 1, the metal shell is formed by butting a bottom shell and a top shell, and the positions of the outer peripheral edges of the bottom shell and the top shell relative to the collar and the ring groove are correspondingly provided with a positioning groove and a positioning tenon which are sleeved and fixed with each other. In one embodiment, the first engagement portion is an externally threaded section and the second engagement portion is an internally threaded section that is threaded with the externally threaded section. In one embodiment, the outer peripheral surface of the tube spring is provided with at least two supporting fins which extend backwards and obliquely corresponding to the sleeve hole position and are used for radially compressing the sleeve hole to form a supporting and fixing structure. In one embodiment, the packing tube is made of metal or plastic.
