Abstract
Description
Technical Field
[0001] The utility model relates to the field of screw products, specifically to a conductive wire-passing screw. Background Art
[0002] A conductive wire-passing screw is a special screw mainly used in electrical connections to conduct current. It is a conductive material with good electrical conductivity, corrosion resistance, high stability, etc. The conductive wire-passing screw is usually made of conductive materials such as copper, aluminum, etc., and can effectively transfer current from one conductor to another. When using the conductive wire-passing screw, it is necessary to operate according to the correct steps to ensure the stability of the connection and the electrical conductivity.
[0003] There are some problems in the existing conductive wire-passing screws during use, such as excessive or insufficient tightening force, which affects the electrical conductivity, and the connecting parts are prone to looseness. Therefore, a new type of conductive wire-passing screw is proposed to solve the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide a conductive wire-passing screw to solve the problems in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solution: a conductive wire-passing screw, including a screw rod and a first nut connected thereto. A threaded section is provided on the outer wall of the screw rod. The threaded section and the screw rod form an inclination angle of less than 90° in the direction inclined to the first nut. A second nut is sleeved on the screw rod in a sliding manner. A thread groove adapted to the threaded section is provided in the inner cavity of the second nut.
[0006] Preferably, the first nut is in a hexagonal cross-section shape. The top of the hexagonal cross-section first nut has a planar area, and a groove is provided in the planar area. The shape of the groove matches the shape of the end of the tightening tool.
[0007] Preferably, the groove is in a shape of "one", "cross", hexagonal square or hexagonal flower.
[0008] Preferably, a boss is provided in the radial direction at one end of the screw rod connecting the first nut. The diameter of the boss is smaller than the diameter of the first nut.
[0009] Preferably, the threaded section on the screw rod rotates along the radial direction of the screw rod, but the center line of the cross-section of the threaded section is not perpendicular to the screw rod.
[0010] Preferably, a conductive layer and an anti-loosening layer are coated on the outer surface of the threaded section. The conductive layer is coated on the entire outer surface of the modified threaded section. The anti-loosening layer is coated on a partial surface of the conductive layer. The area of the anti-loosening layer is smaller than the area of the conductive layer.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention, through the design of a screw, a first nut, a threaded section, a second nut, a threaded groove, a recess, a boss, and a planar area, further utilizes the design of the threaded section angle to allow the threaded section on the screw to rotate radially along the screw. However, the center line of the threaded section cross-section is not perpendicular to the screw, but rather inclined towards the bolt head. The threaded section forms an inclination angle of less than 90° with the screw. When vibration occurs, or when a thrust is applied to the bolt tail, the inner threaded groove of the second nut resists the threaded section on the outer wall of the screw, increasing the friction between the threads. This makes it difficult for the bolt to come out of the second nut, achieving an anti-loosening effect. At the same time, it facilitates better control of the tightening force and improves electrical conductivity. Attached Figure Description

[0023] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a coating anti-coagulation device.
[0024] Please see Figures 1 to 4This utility model provides a technical solution: a conductive wire-passing screw, including a screw rod 1 and a first nut 2 connected thereto. The outer wall of the screw rod 1 is provided with a threaded section 5, and the threaded section 5 forms an inclination angle of less than 90° with the screw rod 1 in the direction of the first nut 2. A second nut 6 is slidably sleeved on the outside of the screw rod 1. The inner cavity of the second nut 6 is provided with a threaded groove 7 that matches the threaded section 5. The first nut 2 has a hexagonal cross-section, and the top of the hexagonal cross-section first nut 2 has a planar area 4. The planar area 4 is provided with a groove 3, and the shape of the groove 3 is similar to that of the first nut 2. The end shape of the tightening tool is matched. The groove 3 is in the shape of "I", "+", hexagonal square or hexagonal flower. The end of the screw 1 connected to the first nut 2 is provided with a boss 8 in the radial direction. The diameter of the boss 8 is smaller than the diameter of the first nut 2. The threaded section 5 on the screw 1 rotates in the radial direction of the screw 1, but the center line of the cross section of the threaded section 5 is not perpendicular to the screw 1. The outer surface of the threaded section 5 is coated with a conductive layer and an anti-loosening layer. The conductive layer is coated on the entire outer surface of the threaded section 5, and the anti-loosening layer is coated on a local surface of the conductive layer. The area of the anti-loosening layer is smaller than the area of the conductive layer.
[0025] It should be noted that the threaded section 5 on the surface of the screw 1 is inclined towards the first nut 2 and rotates radially along the screw 1. The threaded section 5 and the screw 1 form an inclination angle of less than 90 degrees. When it matches the threaded groove 7 in the second nut 6, it can resist large external shaking. The groove 3 can be matched with various different structures and can be adapted to tightening tools. The boss 8 can replace the flat washer that needs to be installed in actual installation. The screw 1 has a boss 8 radially at the end connecting to the first nut 2. The diameter of the boss 8 is smaller than the outer diameter of the first nut 2. In this way, the first nut 2 does not contact the periphery of the installed part during assembly, reducing the paint scratch on the edge. The threaded groove 7 uses a matching internal thread, which can achieve a tight fit and greatly improve the tightness of the device structure. The conductive layer and anti-loosening layer on the surface of the threaded section 5 can enhance the conductivity through the conductive layer and form a tight contact with the inner wall of the screw hole through the anti-loosening layer, thereby achieving the purpose of tight connection.
[0026] The working principle of the above embodiment is as follows: When in use, the operator aligns the tightening tool with the groove 3 above the first nut 2 and tightens it to complete the assembly. The threaded groove 7 in the second nut 6 can be matched with the threaded section 5 on the screw 1 to achieve the fastening effect. When the bolt is vibrated or when a thrust is applied to the tail of the bolt, the internal thread on the threaded groove 7 of the second nut 6 resists the threaded section 5 on the screw 1, increasing the friction between the threaded sections 5. This is equivalent to the internal thread resisting the movement of the external thread, making it difficult for the bolt to come out of the second nut 6, thus playing a role in preventing loosening.
[0027] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
