[0025] In order to thoroughly understand the implementation manners of this application, detailed structures will be presented in the following description. Obviously, the implementation of the implementation manners of this application is not limited to the special details familiar to those skilled in the art. The preferred implementation manners of this application are described in detail below. However, in addition to these detailed descriptions, this application can also have other implementation manners.

Additionally, in the description of the present application, unless otherwise clearly specified and limited, the terms "install", "connect", "join" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0027] The following further elaborates on the embodiments of the present application with reference to the drawings:

[0028] In the first aspect, please refer to Figure 1 , the present application provides a T-shaped wire clamp. The T-shaped wire clamp includes a first connecting pipe 100 and a second connecting pipe 200. The first connecting pipe 100 has a first channel 110, and the first channel 110 penetrates at least one end of the first connecting pipe 100. One end of the second connecting pipe 200 is welded or integrally formed with the pipe wall of the first connecting pipe 100 to form the wire clamp body 300. The second connecting pipe 200 has a second channel 210, and the second channel 210 penetrates the end of the second connecting pipe 200 far from the first connecting pipe 100. The axis of the first connecting pipe 100 is perpendicular to the axis of the second connecting pipe 200.

[0029] In the above implementation process, since the first connecting pipe 100 and the second connecting pipe 200 form the wire clamp body 300 by welding or integral molding, the bolt connection structure is omitted. The first connecting pipe 100 and the second connecting pipe 200 can be electrically connected to the wire by means of crimping. Therefore, when the T-shaped wire clamp is used to connect the wire and the branch wire, the crimping method is directly adopted for connection, and no manual maintenance is required in the later stage, effectively improving the efficiency of power construction and reducing the risk of manual maintenance.

[0030] Optionally, the end of the second connecting pipe 200 can be connected to the pipe wall of the first connecting pipe 100 near the end, or can be connected to the pipe wall in the middle of the first connecting pipe 100. That is, the connection position between the second connecting pipe 200 and the first connecting pipe 100 can be any position on the first pipe wall, and the embodiments of the present application do not limit this.

[0031] During the power construction process, the electrical connection between the branch line and the main line may be the connection between the end of the branch line and the end of the main line. In this case, a structure in which the first channel 110 forms a port on the first connecting pipe 100 can be adopted, and the end of the main line penetrates into the first channel 110 from the port. It is also possible that the end of the branch line is connected to the middle part of the main line. At this time, the main line cannot penetrate into the first channel 110 from the port.

[0032] Please refer to Figures 2 - 7 , in a possible implementation manner, the first connecting pipe 100 includes a main pipe body 120 and a clip 130. One end of the second connecting pipe 200 is welded or integrally formed with the main pipe body 120 to form a wire clamp assembly 300; an installation groove 140 penetrating through both axial ends is formed on the pipe wall of the main pipe body 120, and the clip 130 is snap-connected to the installation groove 140 so that the clip 130 is installed into the installation groove 140 along the axial direction of the main pipe body 120 to block the installation groove 140 and restrict the clip 130 from radially separating from the main pipe body 120.

[0033] In the above implementation process, when connecting the main line and the first connecting pipe 100, the main line can be installed into the first connecting pipe 100 radially from the installation groove 140, and then the clip 130 can be installed into the installation groove 140 axially from the end of the first connecting pipe 100. Finally, a press is used to press the first connecting pipe 100 to form a first crimping portion, thereby completing the electrical connection between the main line and the first connecting pipe 100. It can be seen that the first connecting pipe 100 adopts the matching structure of the main pipe body 120 and the clip 130, which can be applicable to the connection situations of the end and the middle part of the branch line and the main line, effectively expanding the applicable scenarios of the above T-shaped wire clamp.

[0034] In a possible implementation manner, the side walls 141 on both sides of the installation groove 140 extend gradually away from the notch at the outer surface of the main pipe body 120, and the side surfaces 132 on both axial sides of the clip 130 are correspondingly arranged with the side walls 141 on both sides of the installation groove 140.

[0035] In the above implementation process, the side walls 141 on both sides of the installation groove 140 extend inward from the notch at the outer surface of the main body 120 in a gradually diverging trend, that is, the installation groove 140 is a structure that gradually expands inward from the notch at the outer surface of the main body 120, that is, the notch is small, and the bottom opening on the other side opposite to the notch is large, so as to achieve the effect of preventing the clamping piece 130 from radially detaching from the installation groove 140. Preferably, the side walls 141 on both sides of the installation groove 140 are symmetrically arranged. Correspondingly, the side surfaces 132 on both axial sides of the clamping piece 130 are also symmetrically arranged.

[0036] In a possible implementation manner, a snap groove 150 is formed on at least one of the side walls 141 on both sides of the installation groove 140, and a snap protrusion 131 that cooperates with the snap groove 150 is provided on the side surface 132 of the clamping piece 130.

[0037] Optionally, the cross-section of the snap groove 150 is rectangular.

[0038] Preferably, the cross-section of the snap groove 150 is triangular, and one side of the triangle is formed at the notch of the snap groove 150, that is, on the side wall 141 of the installation groove 140.

[0039] Optionally, a snap groove 150 with a triangular cross-section is formed on the side wall 141 on one side of the installation groove 140, and the side wall 141 on the other side is a plane. The snap groove 150 includes an adjacent first groove surface 151 and a second groove surface 152. The first groove surface 151 extends inward from the outer surface of the main body 120 and is connected to the second groove surface 152. The side of the second groove surface 152 away from the first groove surface 151 is connected to the inner surface of the main body 120. Among them, the included angle between the first groove surface 151 and the other side wall 141 of the installation groove 140 is α 1 , 0 < α 1 ≤20°. Limiting α 1 within the above range can reduce the thickness of the two parts on both axial sides of the clamping piece 130, and the thickness of each part increases gradually in the direction away from the wire, that is, the thickness of the side close to the wire is smaller and it will also deform first during the crimping process, which can improve the crimping effect.

[0040] Optionally, as Figure 5 shown, snap grooves 150 with a triangular cross-section are symmetrically arranged on the side walls 141 on both sides of the installation groove 140. Specifically, the snap groove 150 includes a first groove surface 151 and a second groove surface 152. The first groove surface 151 extends inward from the outer surface of the main body 120 and is connected to the second groove surface 152. The side of the second groove surface 152 away from the first groove surface 151 is connected to the inner surface of the main body 120. Among them, the included angle between the first groove surfaces 151 of the two snap grooves 150 is α 2 , 0 < α 2 ≤20°. Limiting α 2Limited within the above range, the thickness of the two parts on the axial sides of the clamping piece 130 can be reduced, and the thickness of each part gradually increases in the direction away from the wire, that is, the thickness of the side close to the wire is smaller, and it will also deform first during the crimping process, which can improve the crimping effect. Among them, the central plane of the first channel 110 corresponding to the connection between the second groove surface 152 and the first groove surface 151 is used as the reference plane, and the included angle between the second groove surface 152 and the reference plane is β 2 , 0 ≤ β 2 ≤ 45°. The second groove surface 152 and the first groove surface 151 cooperate to form a sliding installation angle for the clamping piece 130 to slide and install, so that the clamping piece 130 and the main pipe body 120 are tightened when being pressed, and the compression ratio is smaller.

[0041] In a second aspect, the present application further provides a wire connection structure, which includes a first wire, a second wire, and the T-shaped wire clamp according to any embodiment of the first aspect. The first wire is installed in the first connection pipe 100 and crimped to form a first crimping part, and one end of the second wire is installed in the second connection pipe 200 and crimped to form a second crimping part.
