[0022] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0024] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" 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, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] like Figure 1 As shown, a conductor connecting rod comprises an insulating tube 1, a conductor clamp 2, and an insulating rod 3. The insulating tube 1 is composed of a left insulating tube 101 and a right insulating tube 102; the left insulating tube 101 and the right insulating tube 102 are both provided with conductor clamps 2, and the two groups of conductor clamps 2 are connected by a wire 3; the conductor clamp 2 is composed of a crossed upper bite tongue 201 and a lower bite tongue 202, and the outer side of the lower bite tongue 202 is provided with a fixing groove 2021; the fixing groove 2021 matches the insulating rod 3, and the insulating rod 3 matches the fixing groove after passing through the lower through hole 4 of the insulating tube 1; conical guide openings 5 are provided at both ends of the insulating tube 1.
[0026] like Figure 1-2 As shown, a docking post 1021 is provided at the interface of the right insulating tube 102, a buckle 1022 is provided on the docking post 1021, a buckle groove 1011 is provided on the inner wall of the docking interface of the left insulating tube 101, and the left insulating tube 101 and the right insulating tube 102 are connected and matched through the docking post; a rubber layer (not shown in the figure) is provided on the outer wall of the docking post 1021, and the two groups of insulating tubes are docked in a snap-fitting manner, which is convenient for disassembly and maintenance, and the rubber layer can increase friction and sealing.
[0027] like Figure 1As shown, a torsion spring 6 is provided at the intersection of the upper bite tongue 201 and the lower bite tongue 202, and a return spring 7 is provided between the upper bite tongue 201 and the lower bite tongue 202 outside the torsion spring 6. The torsion spring is a return spring that can provide a double-layer restoring force, thereby increasing the bite force of the conductor clamp to prevent the wire from falling off after connection.
[0028] like Figure 1 , 3 As shown, the upper bite tongue 201 and the lower bite tongue 202 are hinged and crossed by the rotating shaft 8, and the inner walls of the left insulating tube 101 and the right insulating tube 102 are provided with a slide 9, the rotating shaft 8 is matched with the slide 9, and the opening of the slide 9 is located at the docking interface. The slide is used to cooperate with the rotating shaft of the conductor clamp to facilitate the installation and limiting of the conductor clamp.
[0029] like Figure 1 , 3 As shown, the cross-section of the left insulating tube 101 and the right insulating tube 102 is a semicircular cavity, and the slideway 9 is located in the semicircular cavity. The semicircular cavity can be adapted to the conductor clamp and can serve as a bottom limit plate of the conductor clamp to prevent the conductor clamp from rotating around the rotating axis.
[0030] like Figure 1 As shown, a bite tube 10 extends inward from the conical guide opening 5, and the other end of the bite tube 10 matches the open end of the conductor clamp 2. After the conductor clamp is pressed open by the insulating rod, the external wire passes through the conical guide opening and the bite tube in sequence to enter the pressing range of the conductor clamp.
[0031] like Figure 1 As shown, the through hole 4 on the insulating tube 1 is rotatably sealed by the sealing cap 11. After the insulating rod presses the conductor clamp to fix the wires at both ends, the insulating rod is taken out and the through hole is sealed by the sealing cap, which can further achieve dust prevention.
[0032] like Figure 3 As shown, the slideway 9 is configured as a concave groove, and the conductor clamp 2 is limited by a limit plate after being inserted into the slideway. After the rotating shaft of the conductor clamp matches the slideway, displacement will occur when there is no limit device. Therefore, after the conductor clamp is installed, the limit plates are respectively inserted into the left and right insulating tubes. The size of the limit plates is slightly smaller than that of the concave groove. After the two insulating tubes are docked, the relative limit plates will conflict with each other, thereby fixing the conductor clamp. When taking out the conductor clamp, it is only necessary to disassemble the two sets of insulating tubes and then take out the limit plates.
[0033] The working principle of the utility model is explained as follows: when in use, the connecting rod can be assembled in advance, which is more convenient and quick when connecting the wires on site; the assembly steps are as follows: the rotating shaft of the conductor clamp is slid inward along the slide and fixed by the limit plate, and then the two groups of insulating tubes are connected to realize the assembly of a connecting rod; when connecting the wires, the conductor clamp is pressed by the insulating rod, and then the wire is inserted into the conical guide port and matched with the conductor clamp, and the operation is repeated at the other end to realize the connection of the wires at both ends. After the connection, there is no need to cover with insulating tape, which greatly improves the efficiency.
[0034] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
