Description

Technical Field

[0001] This invention relates to a wire stop, and more particularly to a wire stop structure with conductive function. Background Technology

[0002] With the rapid development of technology, electronic devices, such as audio-visual playback devices or electronic components inside computers, such as integrated circuits, usually have a default grounding circuit on the motherboard. This grounding circuit is coupled to the ground wire in the power supply line to conduct leakage current and discharge it to the earth, thus preventing harm to the human body in the event of a leakage. Furthermore, due to poor insulation or a humid environment, the casing of such electronic devices may accumulate static electricity, which can lead to electric shock accidents in severe cases.

[0003] In particular, when the casing of the electronic device is made of metal, the static electricity on the metal casing cannot be discharged because the metal casing cannot be connected to the connecting wire in the aforementioned power cord. As a result, the static electricity often causes electric shock to people, which urgently needs to be improved. Summary of the Invention

[0004] The main objective of this invention is to provide a wire stop structure for wires, which can be attached to a metal casing so that the static electricity accumulated in the metal casing can be discharged through a power line connected to the wire stop structure and having a grounding wire, thereby avoiding electric shock to personnel.

[0005] To achieve the aforementioned objectives, the present invention provides a wire guide structure for wires, comprising a metal fixing tube with an axially extending through hole at its front end for a power cord to pass through, and a fixing mechanism for mounting on a metal casing. A larger diameter sleeve is connected within the through hole, and the sleeve and the adjacent surface of the through hole form an abutment surface. A first joint portion is provided at the rear end of the fixing tube. A metal spring has its front section fitted within the sleeve hole and has an axially extending slot on its outer circumferential surface. This slot connects to a wire groove for the power cord to pass through and be positioned. At least two anti-retraction wings extend obliquely forward from the inner circumferential surface of the wire groove. These at least two anti-retraction wings are used to clamp the metal mesh layer within the power cord, and the metal mesh layer is electrically connected to the grounding wire within the power cord. A clamping tube has an axially extending positioning hole for the rear section of the spring to be accommodated and for the power cord to pass through. The front end of the positioning hole has a second joint portion that engages with the first joint portion.

[0006] In one embodiment, the rear section of the spring forms a first tapered section that tapers rearward, and the first tapered section is adjacent to the constriction section; and the rear sections of the clamping tube and the positioning hole each form a second tapered section that tapers rearward and a tapered inner wall corresponding to the position of the first tapered section, and the tapered inner wall exerts a clamping effect on the first tapered section, so that the constriction section tightens and fixes the plastic outer sheath of the power cord.

[0007] In one embodiment, the fixing mechanism includes a collar and an annular groove that are radially adjacent to each other on the outer peripheral surface of the front end of the fixing tube 1; and the metal shell is formed by connecting a bottom shell and a top shell, and the bottom shell and the top shell are provided with positioning grooves and positioning tenons that are mutually sleeved and fixed at their respective positions relative to the collar and the annular groove on their outer periphery.

[0008] In one embodiment, the first joint is an external thread segment, and the second joint is an internal thread segment that is screwed into the external thread segment.

[0009] In one embodiment, the outer peripheral surface of the tube spring is provided with at least two support flaps that extend obliquely backward and are radially compressed by the sleeve hole to form support and fixation.

[0010] In one embodiment, the clamping tube is made of metal or plastic. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] like Figures 1 to 8As shown, the wire stop structure of the present invention for wires basically includes a fixing tube 1, a spring 2, and a clamping tube 3. The fixing tube 1 and the spring 2 are both made of conductive materials, such as metal, while the clamping tube 3 can be made of conductive materials, such as metal, or non-conductive materials, such as plastic.

[0021] The front end of the fixing tube 1 has an axial through hole 11 for the power cord 4 (shown in Figure 4) to pass through, and is provided for mounting to the metal housing 5 (shown in Figure 5). Figure 6 The fixing mechanism includes a collar 12 and an annular groove 13 radially adjacent to each other on the outer peripheral surface of the front end of the fixing tube 1. A larger diameter sleeve hole 14 is connected inside the through hole 11, and the adjacent surfaces of the sleeve hole 14 and the through hole 11 form an abutment surface 15 (shown in...). Figure 8 The rear end of the fixed tube 1 is provided with a first joint 16, such as an external thread section.

[0022] The spring 2 is made from a metal sheet through processes such as cutting, stamping, and rolling. The front section of the spring 2 is fitted into the sleeve hole 14, and an axial groove 21 is provided on its outer circumferential surface, making the spring 2 essentially an elastic body with radial expansion and contraction capabilities. Furthermore, the spring 2 also has an axial groove 22 that communicates with the groove 21 and allows the power cord 4 to pass through and be positioned. Figures 1 to 3 As shown, the outer peripheral surface of the tube spring 2 is provided with at least two rearwardly extending support winglets 23 at the position corresponding to the sleeve hole 14 of the fixed tube 1; and the inner peripheral surface of the groove 22 is provided with at least two forwardly extending anti-reverse winglets 24.

[0023] Furthermore, the rear section of the tube spring 2 forms a first tapered section 25 that tapers rearward, and the first tapered section 25 is adjacent to the constriction section 26.

[0024] The clamping tube 3 is axially provided with a positioning hole 31 for the rear section of the tube spring 2 to be fitted and for the power cord 4 to pass through. The front end of the positioning hole 31 is provided with a second joint 32 that engages with the first joint 16, for example, an internally threaded section. The rear section of the clamping tube 3 also forms a second tapered section 33 that tapers rearward at the position corresponding to the first tapered section 25. The second tapered section 33 forms a tapered inner wall 34 in the positioning hole 31 to provide a clamping effect on the first tapered section 25.

[0025] As shown in Figure 4, the power cord 4 is a prior art technology, comprising two wires 41, a grounding wire 42 wound around the wires 41, a metal mesh layer 43 covering the wires 41 and the grounding wire 42, and a plastic sheath 44 covering the metal mesh layer 43. The grounding wire 42 is a bare metal wire and is in contact with the metal mesh layer 43 to form an electrical connection.

[0026] When assembling the wire stop structure with the power cord 4, the clamping tube 3 and the spring tube 2 are first sequentially inserted into the power cord 4, and the rear section of the spring tube 2 is fitted into the positioning hole 31, so that the at least two anti-retraction flaps 24 are positioned precisely at the metal mesh layer 43. Subsequently, the metal mesh layer 43, the wires 41, and the grounding wire 42 are passed out through the through hole 11 of the fixing tube 1. Finally, the first joint 16 of the fixing tube 1 is combined with the second joint 32 of the clamping tube 3, for example, by screwing, so that the front end of the spring tube 2 abuts against the abutment surface 15, while the first tapered section 25 of the rear end abuts against the tapered inner wall 34 in the positioning hole 31 and is subjected to radial external force, causing the slot 21 to contract, and the constricting section 26 to gradually tighten the plastic outer sheath 44 of the power cord 4, thereby fixing the power cord 4.

[0027] The anti-retraction flaps 24 also clamp and fix the metal mesh layer 43. Since the extension direction of the anti-retraction flaps 24 is opposite to the pulling direction of the power cord 4, they can prevent the power cord 4 from retracting. The support flaps 23 are radially compressed by the sleeve hole 14 of the fixing tube 1 to form a support and fixation effect. Figure 5 shows a perspective view of the wire stop structure combined with the power cord 4.

[0028] Figures 6 to 8 This is a diagram illustrating the connection of the wire harness structure with the power cord to an electronic device. For example... Figure 6 As shown, the electronic device 5 includes a metal casing 51 formed by the mating of a bottom casing 511 and a top casing 512, and a circuit board 52 fixed inside the bottom casing 511. The two wires 41 of the power cord 4 and the ground wire 42 are coupled to the relevant circuits on the circuit board 52. The bottom casing 511 and the top casing 512 are respectively provided with positioning grooves 513 and positioning tenons 514 on their outer peripheries relative to the collar 12 and the annular groove 13, which are mutually fitted and fixed. Finally, the top casing 512 and the bottom casing 511 are mated together to form the electronic device. Figure 7 The 3D diagram shown.

[0029] Figure 8 for Figure 7 The cross-sectional view taken along line AA clearly shows that the static electricity on the metal shell 51 is conducted to the tube spring 2 through the fixed tube 1. Since the tube spring 2 and the anti-reverse wing 24 sandwich the metal mesh layer 43, and the metal mesh layer 43 is electrically connected to the grounding wire 42, the static electricity is also conducted and released through the grounding wire 42, thus avoiding electric shock injury to personnel.

[0030] Therefore, the benefit gained from the implementation of this invention is that, since the wire stop structure has the function of conducting electricity, when it is connected to the metal shell, the static electricity of the metal shell can be conducted and released through the power line connected to the wire stop structure and having a grounding wire, thereby avoiding electric shock to personnel. It can be described as a great invention that has never been seen before in the same kind of product.

[0031] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
