[0046] The embodiments of the present application are further described in detail below with reference to the accompanying drawings:

[0047] The present application provides a wire connector, which includes a connecting tube 100, at least one gasket 200 and at least one abutting piece 400. The connecting tube 100 includes a connecting hole 110 that runs through both ends of the connecting tube along the axis and at least one through hole 120 opened on the tube wall of the connecting tube 100. The gasket 200 is used to be installed in the connecting hole 110 to cooperate with the inner wall of the connecting hole 110 to form a connecting cavity 300 for accommodating the wire to be connected. The connecting cavity 300 is connected to the through hole 120. One end of the abutting piece 400 passes through the through hole 120 and extends into the connecting hole 110 and is fixedly connected to the through hole 120 to abut the wire to be connected in the connecting hole 110. The connecting tube 100 and the abutting piece 400 are both conductors.

[0048] In the above implementation process, the connection hole 110 passes through the two ends of the connection tube 100 to form two ports, and the two ports are used to insert a wire respectively, thereby connecting the two wires. If the diameters of the two wires are the same and fit the inner diameter of the connection hole 110, the gasket 200 is not required, and the two wires are directly inserted into the two ends of the connection hole 110 respectively, and then the fastening member 400 is used to pass through the through hole 120 to fasten the wire in the connection hole 110, thereby achieving structural connection and electrical conduction of the two wires. If the diameters of the two wires to be connected are inconsistent, wherein the diameter of the first wire is the same as or slightly smaller than the inner diameter of the connecting hole 110, and the diameter of the second wire is smaller than the inner diameter of the connecting hole 110, then the first wire can be directly extended into one end of the connecting hole 110 and fastened together with the fastening member 400, and a gasket 200 is placed at the other end, and the second wire is inserted into the connecting cavity 300 formed by the gasket 200 and the connecting hole 110, that is, the gasket 200 is used to fill the gap between the wire with a smaller diameter and the connecting hole 110, and finally the fastening member 400 is used to press the wire inward from the tube wall of the connecting member, thereby achieving structural connection and electrical conductivity of two wires of different sizes.

[0049] Optionally, the material of the connecting tube 100 can be selected according to the material of the wire to be connected, and can be copper or aluminum, etc., which is not limited in the embodiment of the present application.

[0050] Preferably, the gasket 200 is also a conductor, which can effectively improve the electrical connection performance of the two wires.

[0051] Optionally, the length of the gasket 200 is more than two. The cross-sectional areas of the multiple gaskets 200 can be the same or different.

[0052] When the cross-sectional areas of the plurality of gaskets 200 are the same, two of the gaskets 200 are respectively placed at the two ends of the connection hole 110. The wire connector can also be used to connect two wires with the same diameter and smaller than the inner diameter of the connection hole 110.

[0053] Preferably, the cross-sectional area of ​​each gasket 200 is different, so that the wire connector can be applied to a wider range of wire sizes. For example, two gaskets 200 with different cross-sections are respectively installed or placed at both ends of the connection hole 110, so that two wires with different diameters and both smaller than the inner diameter of the connection hole 110 can be connected.

[0054] Optionally, the extension length of each gasket 200 may be less than or equal to half the extension length of the connection hole 110 . Each gasket 200 is used to reduce the gap at one end of the connection hole 110 and is suitable for filling the gap between the connection hole 110 and a wire to be connected.

[0055] Optionally, the extension length of each gasket 200 can also be equal to the extension length of the connecting hole 110. When each gasket 200 is placed in the connecting hole 110, it can directly reduce the space at both ends of the connecting hole 110, which is suitable for connecting two wires of the same size and smaller than the inner diameter of the connecting hole 110.

[0056] In a possible implementation, the gasket 200 is formed with grooves 210 running through both ends thereof, the inner surface of the groove 210 and the wall of the connecting hole 110 opposite thereto form a connecting cavity 300 , and the inner surface of the groove 210 is an arc-shaped curved surface as a whole.

[0057] In the above implementation process, since the cross-street surfaces of most conductors are circular or nearly circular structures, compared with the planar structure, the arc-shaped groove 210 structure provided on the gasket 200 is more conducive to increasing the contact area between the gasket 200 and the conductor, reducing the gap between the conductor and the gasket 200 and the connecting hole 110, improving the stability of the structural connection and the electrical connection, and facilitating the insertion of the gasket 200 between the conductor and the connecting hole 110 or the insertion of the conductor into the connecting cavity 300 between the gasket 200 and the connecting hole 110.

[0058] In a possible implementation manner, a plurality of protruding teeth 220 are formed on the surface of the gasket 200 on a side close to the through hole 120 .

[0059] It should be understood that the surface of the gasket 200 close to the through hole 120 refers to the surface that forms the connecting cavity 300 with the tube wall of the connecting tube 100 on the side of the through hole 120 when the gasket 200 is installed in the connecting hole 110 .

[0060] In the above implementation process, a convex tooth 220 is set on the surface of the gasket 200 for contacting the wire. During the process of the clamping member 400 being pressed, due to the pressure from the clamping member 400, the convex tooth 220 on the gasket 200 can easily pierce the oxide layer on the surface of the wire, thereby effectively improving the electrical connection performance between the wire and the connector.

[0061] Optionally, the protruding teeth 220 extend along the length direction of the gasket 200. When the gasket 200 is formed with a groove 210 and the protruding teeth 220 are arranged on the inner surface of the groove 210, it is convenient to process the protruding teeth 220 along the length direction of the gasket 200.

[0062] In a possible implementation, the gasket 200 has an outer peripheral surface 230 for contacting the inner wall of the connecting hole 110 , and the outer peripheral surface 230 is an arc-shaped curved surface that fits the inner wall of the connecting hole 110 .

[0063] In the above implementation process, the connection hole 110 is set to be circular to adapt to the shape of the wire, and the outer peripheral surface 230 of the gasket 200 that contacts the inner wall of the connection hole 110 is also designed to be an arc-shaped surface, which can increase the contact area between the gasket 200 and the inner wall of the connection hole 110 and improve the stability of the structural connection and the electrical connection.

[0064] In a possible implementation, a plurality of grooves 130 are formed on the tube wall of the connection hole 110 away from the through hole 120 , and a toothed bar 140 is formed between two adjacent grooves 130 .

[0065] The tube wall of the connecting hole 110 away from the through hole 120 should be understood to include the surface of the connecting hole 110 for contacting the gasket 200 .

[0066] In the above implementation process, the toothed strip 140 formed by the groove 130 on the inner wall of the connection hole 110 can increase the friction between the gasket 200 and the connection tube 100, and effectively improve the stability of the structural connection between the connection tube 100, the gasket 200 and the wire. In addition, when the abutting member 400 abuts against the wire in the connection cavity 300, the toothed strip 140 will pierce the oxide layer on the surface of the wire due to the pressure from the abutting member 400, and the oxide layer on the surface of the toothed strip 140 will also be destroyed, so that the electrical connection performance between the connection tube 100, the gasket 200 and the wire can be improved.

[0067] In a possible implementation, the groove 130 is an arc-shaped groove 130 extending circumferentially along the connecting hole 110 , and a plurality of arc-shaped grooves 130 are arranged along the axial direction of the connecting hole 110 .

[0068] Preferably, the circumferential dimension of the arc-shaped groove 130 is the same as the circumferential dimension of the gasket 200 .

[0069] Preferably, the length of the axis of the plurality of arc-shaped grooves 130 along the axial direction of the connection hole 110 is equal to the axial length of the connection hole 110. That is, the arc-shaped grooves 130 are laid from one end to the other end of the connection hole 110. When a wire with the same or similar diameter is directly inserted into one end of the connection hole 110 without the gasket 200, the toothed strips 140 formed by the arc-shaped grooves 130 at this end directly contact the wire, which can increase the stability of the structural connection between the connection hole 110 and the wire and the electrical connection performance.

[0070] Optionally, the axes of the plurality of arc grooves 130 are parallel to the axis of the connection hole 110, and the axes of the plurality of arc grooves 130 are located on the side of the axis of the connection hole 110 away from the through hole 120. The axes of the arc grooves 130 are parallel to the axes of the connection hole 110 but not collinear, i.e., eccentrically arranged, so that the middle of the arc grooves 130 are deep and gradually become shallower toward both ends, which facilitates the processing of the arc grooves 130.

[0071] In a possible implementation, the wire connector further includes a limiting component, which acts on the gasket 200 and the connecting tube 100 to limit the gasket 200 to a predetermined position in the connecting hole 110 .

[0072] In the above implementation process, compared with directly placing the gasket 200 in the connecting hole 110, a limiting assembly is used to limit the gasket 200 to a predetermined position in the connecting hole 110, which can prevent or reduce the movement and rotation of the gasket 200 relative to the connecting pipe 100 during the tightening process of the tightening member 400.

[0073] Optionally, the limiting assembly includes a limiting block 240 formed on the outer peripheral surface 230 of the gasket 200 and a limiting groove 150 provided on the wall of the connecting hole 110, and the limiting block 240 is used to be installed in the limiting groove 150. Preferably, the limiting block 240 and the limiting groove 150 are adapted in shape and size, and the limiting block 240 on the gasket 200 is installed in the limiting groove 150, which can effectively prevent the gasket 200 from axially moving or circumferentially rotating relative to the connecting tube 100 during the tightening process, thereby ensuring the stability of the structural connection and the electrical connection.

[0074] Optionally, the positions of the limiting block 240 and the limiting groove 150 can be interchanged, that is, the limiting block 240 is arranged on the tube wall of the connecting hole 110 , and the limiting groove 150 is opened on the gasket 200 .

[0075] Optionally, the limiting groove 150 is provided at the end of the connecting tube 100, and a notch 151 is formed at the end of the connecting tube 100. The gasket 200 can be directly pressed against the inner wall of the connecting tube 100 and pushed into the connecting hole 110, and the limiting block 240 enters the limiting groove 150 from the notch 151, so that the gasket 200 can be installed conveniently and quickly.

[0076] In a possible implementation, the axis of the connection hole 110 is parallel to the axis of the connection tube 100 , and the axis of the connection hole 110 is located on a side of the axis of the connection tube 100 away from the through hole 120 .

[0077] In the above implementation process, the connecting hole 110 and the connecting tube 100 are eccentrically arranged, and the connecting hole 110 is eccentric in the direction away from the through hole 120, so that the tube wall of the connecting tube 100 on the side where the through hole 120 is located is thicker, which can effectively ensure the strength of the tube wall of the connecting tube 100 on the side of the through hole 120.

[0078] It should be understood that the axis of the connecting hole 110 and the axis of the connecting tube 100 being parallel means being parallel but not collinear, that is, the situation where the axis of the connecting hole 110 and the axis of the connecting tube 100 coincide with each other is not included.

[0079] Optionally, a through hole 120 is provided at one end of the connecting tube 100, and no through hole 120 is provided at the other end. The end with the through hole 120 can use a fastening member 400 to fasten the wire, and the end without the through hole 120 can be crimped to connect the wire to the connecting tube 100.

[0080] In a possible implementation, two groups of through holes 120 are formed on the connecting tube 100 . The two groups of through holes 120 are respectively formed at two ends of the connecting tube 100 , and each group of through holes 120 includes at least one through hole 120 .

[0081] In the above implementation process, through holes 120 are provided at both ends of the connecting tube 100 , that is, both ends of the connecting tube 100 can use the fastening members 400 to pass through the through holes 120 to fasten the wires to achieve the connection between the wires and the connecting tube 100 .

[0082] Optionally, at least one group of through holes 120 includes more than two through holes 120 , and the axes of the multiple through holes 120 in each group of through holes 120 are parallel and arranged in sequence along the axial direction of the connecting tube 100 , that is, the multiple through holes 120 press the wires along the axis of the connecting tube 100 .

[0083] Preferably, at least one group of through holes 120 includes more than two through holes 120, and the axes of two adjacent through holes 120 in each group of through holes 120 are at a predetermined angle and are arranged alternately along the axial direction of the connecting hole 110. That is, the multiple abutting members 400 at the corresponding ends of the connecting tube 100 can abut the wire from different radial directions of the wire, which can improve the fixing effect of the wire. Further, the angle between the axes of two adjacent connecting holes 110 is 10°-60°, specifically, 10°, 20°, 40° or 60°.

[0084] Preferably, the two groups of through holes 120 each include more than two through holes 120 , that is, each end of the connecting tube 100 can be fixed with multiple abutting members 400 to fix the wires.

[0085] Preferably, the axis of the through hole 120 is arranged along the radial direction of the connecting hole 110. That is, the pressing member 400 can press the wire along the radial direction of the connecting hole 110 or the wire, reduce or avoid the generation of axial force, and improve the fixing effect.

[0086] Optionally, the fastening member 400 is a bolt, an inner thread is provided on the inner wall of the through hole 120, and the fastening member 400 and the through hole 120 are fixedly connected in the form of a threaded connection, so that the connecting pipe 100 can be reused.

[0087] Optionally, the fastening member 400 may also be an expansion nail, and the through hole 120 is a smooth hole.
