Description

Technical Field

[0001] This utility model relates to the field of wire clamp technology, specifically to an anti-slip electrical wire clamp. Background Technology

[0002] A wire clamp is a connecting accessory used in circuits to connect two sections of wire. Its core is usually made of iron or aluminum. While ensuring good contact, it also needs to have a certain tensile strength to maintain the stability and safety of power transmission.

[0003] When using wire clamps, the insulation layer at the wire connection needs to be removed to expose the metal core. The core is then brought into contact with and fixed to the metal part on the wire clamp. The fixing method is generally to press the core to the metal part with external force, relying on the friction of the core to resist the pulling of the external force, such as the anti-slip practical wire clamp disclosed in the prior art with the publication number CN209298382U.

[0004] The core of a conductor is generally composed of multiple metal wires with a circular cross-section, while the metal part of the clamp is a complete unit. When fixed, the contact area between the metal wires and the metal part on the clamp is small, which leads to insufficient friction between the two when subjected to tension. Therefore, the fixing strength of the clamp for the conductor in the prior art needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide an anti-slip electrical wire clamp, which increases the contact area of ​​the metal wire and copper wire during fixing by uniformly mixing the metal wire and copper wire of the conductor core and pressing them together in the conductive groove, thereby greatly improving the fixing strength and tensile strength of the conductor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip electrical cord clamp, comprising two outer shells, a connecting wire between the two outer shells, a cover plate on the top of the outer shells by screws, and a rubber pressure block fixed at the bottom of the cover plate;

[0007] A pad is fixedly provided on the inner wall of the outer shell. A conductive groove is embedded at the top of the pad. The two ends of the connecting wire are fixedly connected to the conductive grooves inside the two outer shells respectively. Multiple copper wires are fixedly provided on the inner wall of the conductive groove.

[0008] Furthermore, protrusions are fixedly provided on both sides of the outer shell, and two positioning pressure plates are rotatably connected to the top of the protrusions. One end of the positioning pressure plate extends to the top of the cover plate, which can press and fix the cover plate.

[0009] Furthermore, a bellows is provided between the two protrusions on the same side, and a buffer spring is provided inside the bellows. The two ends of the buffer spring are fixedly connected to the two protrusions respectively. When the buffer spring is not pulled by external force, the length of the connecting line is greater than the distance between the two shells.

[0010] Furthermore, a plug hole is provided on the side of the outer casing away from the connecting wire. Two baffles are provided on the side of the outer casing away from the connecting wire by screws. The two baffles are symmetrically arranged on both sides of the plug hole. A semi-circular sealing strip is fixed on the baffle. The two semi-circular sealing strips can be fastened to form a complete sealing ring. The inner diameter of the sealing ring is smaller than the inner diameter of the plug hole and smaller than the outer diameter of the wire.

[0011] Furthermore, the housing is equipped with a fastening assembly, which includes two compression rollers. The lower compression roller is rotatably connected to the inner wall of the housing, and the upper compression roller is rotatably connected to end plates at both ends. The end plates are fixedly located at the bottom of the cover plate. The two compression rollers are arranged symmetrically above and below each other. The surface of the compression rollers is covered with a layer of elastic rubber. The distance between the two compression rollers is smaller than the diameter of the wire, thereby enabling the wire to be pressed and fixed.

[0012] Furthermore, a clamping plate is fixedly provided on the side of the extrusion roller facing the pad, and an anti-slip strip is fixedly provided on the end of the clamping plate away from the extrusion roller.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. By mixing the metal wires and copper wires of the conductor core evenly, and then pressing and fixing the metal wires and copper wires together in the conductive groove, the contact area of ​​the metal wires during fixing is increased, thereby greatly improving the fixing strength and tensile strength of the conductor.

[0015] 2. By setting a fastening component, the wire entering the housing is clamped between two extrusion rollers. The tension on the wire causes the extrusion rollers to rotate and the anti-slip strip to further clamp the wire, thereby converting the tension on the wire into a clamping force. The greater the tension, the greater the clamping force, further reinforcing the wire and preventing it from falling off due to the tension. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The anti-slip electrical cable clamp shown includes two outer shells 1, with a connecting wire 4 between the two outer shells 1. The top of the outer shell 1 is provided with a cover plate 2 by screws, and the bottom of the cover plate 2 is fixed with a rubber pressure block 10. Both the outer shell 1 and the cover plate 2 are made of insulating plastic.

[0026] A pad 101 is fixedly provided on the inner wall of the outer shell 1. A conductive groove 102 is embedded at the top of the pad 101. The two ends of the connecting wire 4 are fixedly connected to the conductive grooves 102 inside the two outer shells 1 respectively. Multiple copper wires 103 are fixedly provided on the inner wall of the conductive grooves 102.

[0027] During connection, the outer insulation of the wire is removed, and one end of the wire, along with the exposed core, is inserted into the outer casing 1. After entering the outer casing 1, the copper wire that makes up the core is inserted into the conductive groove 102 and mixed with the copper wire 103. After the two are mixed evenly, the cover plate 2 is placed on top and fixed to the top of the outer casing 1, so that the rubber pressure block 10 is embedded downward into the conductive groove 102 and the mixed core and copper wire 103 are pressed and fixed together. The copper wire 103 and the metal wire that makes up the core are fully mixed evenly, which increases the contact area of ​​the metal wire during fixing, thereby greatly improving the fixing strength and tensile strength of the wire.

[0028] Two wires are connected to the inside of the two housings 1 in the same way. One of the wires is connected to the terminal of the electrical equipment, thereby completing the connection of the electrical equipment's power transmission line using the wire clamp.

[0029] The cover plate 2 needs to be pressed and fixed to the top of the outer casing 1 and tightened, as follows: Figure 1 , 5 As shown, protrusions 5 are fixed on both sides of the outer shell 1. Two positioning pressure plates 6 are rotatably connected to the top of the protrusions 5. One end of the positioning pressure plate 6 extends to the top of the cover plate 2, which can press and fix the cover plate 2.

[0030] A bellows 3 is provided between two protrusions 5 on the same side. A buffer spring 301 is provided inside the bellows 3. The two ends of the buffer spring 301 are fixedly connected to the two protrusions 5 respectively. When the buffer spring 301 is not pulled by external force, the length of the connecting line 4 is greater than the distance between the two outer shells 1.

[0031] After the cover plate 2 is placed on the top of the outer shell 1, in order to ensure that the cover plate 2 is tightly closed, the positioning pressure plate 6 can be rotated and pressed on the top of the cover plate 2, thereby providing additional fixing force for the cover plate 2, improving the fixing strength of the cover plate 2, and preventing the cover plate 2 from being pushed open by the wires inside the outer shell 1. A bellows 3 and a buffer spring 301 are set between the two outer shells 1. When the wire clamp is pulled by an external force, both the bellows 3 and the buffer spring 301 will be stretched. The elastic force generated by the stretched buffer spring 301 plays a buffering role and improves the tensile strength of the wire clamp.

[0032] The wires need to be connected inside the housing 1 and also sealed within the housing 1, such as... Figure 2 , 3 As shown, the outer shell 1 has a plug hole 9 on the side away from the connecting line 4. Two baffles 8 are provided on the side of the outer shell 1 away from the connecting line 4 by screws. The two baffles 8 are symmetrically arranged on both sides of the plug hole 9. A semi-circular sealing strip is fixed on the baffle 8. The two semi-circular sealing strips can be fastened to form a complete sealing ring. The inner diameter of the sealing ring is smaller than the inner diameter of the plug hole 9 and smaller than the outer diameter of the wire.

[0033] When connecting, the wire is inserted into the outer casing 1 through the plug hole 9. After the wire is connected and fixed, two baffles 8 are symmetrically installed at the plug hole 9. The semi-circular sealing strips on the two baffles 8 can be fastened together to form a complete sealing ring. The sealing ring is tightly fastened to the outer end of the wire, thereby playing a sealing role and preventing external dust and moisture from entering the outer casing 1.

[0034] To further improve the strength of the wire connection, such as Figure 2-4As shown, the housing 1 is equipped with a fastening assembly 7, which includes two compression rollers 701. The lower compression roller 701 is rotatably connected to the inner wall of the housing 1, and the upper compression roller 701 is rotatably connected to end plates at both ends. The end plates are fixedly mounted on the bottom of the cover plate 2. The two compression rollers 701 are symmetrically arranged vertically. The surface of the compression rollers 701 is covered with a layer of elastic rubber. The distance between the two compression rollers 701 is smaller than the diameter of the wire, so that the wire can be pressed and fixed.

[0035] A clamping plate 702 is fixedly provided on the side of the extrusion roller 701 facing the pad block 101, and an anti-slip strip 703 is fixedly provided on the end of the clamping plate 702 away from the extrusion roller 701.

[0036] The wire is inserted into the housing 1 through the plug hole 9 and connected to the conductive groove 102. During this process, the wire rests on the lower compression roller 701. After the cover plate 2 is placed on the top of the housing 1, the upper compression roller 701 presses down on the top of the wire, thus clamping the wire between the two compression rollers 701. The wire is in a bent state between the fastening component 7 and the pad 101 to allow for pulling. Once the wire is subjected to tension, the excess wire will be pulled outward. The moving wire causes the compression roller 701 to rotate, and the two clamping plates 702 rotate accordingly. After rotation, one end of the clamping plates 702 moves closer to each other and finally causes the anti-slip strip 703 to clamp the upper and lower sides of the wire, thereby converting the tension on the wire into a clamping force. The greater the tension, the greater the clamping force, further reinforcing the wire and preventing it from falling off due to tension.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
