Description

Technical Field

[0001] The utility model relates to the field of wire and cable connection, in particular to a wire splitting device for a transmission line. Background Art

[0002] The strain clamp on a transmission line is an important electrical appliance. Its drainage clamp needs to bear the pressure of the conductor and also has good electrical performance. The existing drainage clamp adopts a single-plate - single-plate crimping structure, and two smooth and flat drainage plates are crimped together with bolts.

[0003] Due to the contact surface between the two existing drainage plates being perpendicular to the horizontal ground and smooth, only the fixing device between the two drainage plates provides pressure, resulting in insufficient tightness between the contact surfaces. The non - tight fit between the contact surfaces of the drainage plates is easily affected by the natural environment, leading to a decline in the performance of the drainage clamp, and further affecting the stable operation of the transmission line. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the following problems existing in the prior art: Due to the contact surface between the two existing drainage plates being perpendicular to the horizontal ground and smooth, only the fixing device between the two drainage plates provides pressure, resulting in insufficient tightness between the contact surfaces. The non - tight fit between the contact surfaces of the drainage plates is easily affected by the natural environment, leading to a decline in the performance of the drainage clamp, and further affecting the stable operation of the transmission line.

[0005] To solve the problems existing in the prior art, the utility model provides a wire splitting device for a transmission line, which includes a conductive seat. At least one screw is arranged inside the conductive seat. A pressing block extending to the inside of the conductive seat is sleeved outside the screw, and a nut sleeved on the end of the screw is arranged above the pressing block.

[0006] Preferably, both of the two inner parts of the conductive seat have cavities. The two cavities of the conductive seat are arranged in an inclined shape and are arranged end - to - end.

[0007] Preferably, the bottom end of the pressing block is adapted to the inner size of the conductive seat, and the bottom end of the pressing block is in a fitting state with the middle part of the inner side of the conductive seat.

[0008] Preferably, both sides of the bottom end of the pressing block have inclined contact surfaces, and the two contact surfaces of the pressing block are respectively adapted to the inclined angles of the two cavities of the conductive seat.

[0009] Preferably, a plurality of convex blocks are arranged on the inner sides of the two cavities of the conductive seat and on the contact surfaces of the pressing block, and the cross - section of the convex blocks is triangular.

[0010] Preferably, the pressing block and the convex block of the conductive base are arranged in a staggered manner.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By screwing the nut, the pressing block moves towards the inside of the conductive base with pressure, so that the pressing block squeezes the ends of the main wire and the branch wire inside the conductive base, fixing them inside the conductive base. At the same time, the staggered convex blocks of the pressing block and the conductive base squeeze simultaneously, improving the stability of the main wire and the branch wire. Secondly, the end of the branch wire is at the highest position of another cavity of the conductive base between the branch wire body, so that the cavity of the conductive base has resistance to the wire, further improving the stability of wire installation.

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention.

[0019] The specific embodiments of the present utility model will be described below in conjunction with the drawings.

[0020] Embodiment 1

[0021] As Figures 1-4 shown, a wire splitting device for a power transmission line includes a conductive base 1. At least one screw 4 is arranged inside the conductive base 1. A pressing block 2 extending to the inside of the conductive base 1 is sleeved outside the screw 4. A nut 3 sleeved on the end of the screw 4 is arranged above the pressing block 2.

[0022] The interior of the conductive base 1 has two cavities. The two cavities of the conductive base 1 are arranged obliquely and are arranged end to end. This structure makes the highest points of the two cavities of the conductive base 1 located at both ends of the conductive base 1 respectively.

[0023] The bottom end of the pressing block 2 is adapted to the inner size of the conductive base 1, and the bottom end of the pressing block 2 is in a fitting state with the middle part of the inner side of the conductive base 1, which is used to contact the bottom end of the pressing block 2 with the conductive base 1, so that wires with different diameters can be placed inside the conductive base 1.

[0024] Both sides of the bottom end of the pressing block 2 have inclined contact surfaces. The two contact surfaces of the pressing block 2 are respectively adapted to the inclined angles of the two cavities of the conductive base 1. This structure is used to make the pressing block 2 fully contact the wires inside the cavities of the conductive base 1.

[0025] A plurality of bumps are provided on the inner sides of the two cavities of the conductive base 1 and on the contact surfaces of the pressing block 2, and the cross-section of the bumps is triangular. The bumps of the pressing block 2 and the conductive base 1 are arranged in a staggered manner. When the pressing block 2 moves inward to the conductive base 1 to squeeze the wire, the bumps can increase the resistance between the wire and the conductive base 1 and the pressing block 2, and improve the stability of wire installation.

[0026] Working principle:

[0027] During use, place the main line of the transmission wire inside one cavity of the conductive base 1 and make one cavity of the conductive base 1 horizontal. The inclination of the other cavity increases. Sleeve the pressing block 2 on the outside of the screw 4 and move it towards the conductive base 1. Sleeve the nut 3 on the end of the screw 4. At the same time, insert the end of the branch wire from the highest point to the lowest point of the other cavity of the conductive base 1 and insert it inside the other cavity of the conductive base 1. Then turn the nut 3 to make the pressing block 2 move towards the inside of the conductive base 1 with pressure, so that the pressing block 2 squeezes the main line and the end of the branch line inside the conductive base 1 to fix them inside the conductive base 1. At the same time, the staggered bumps of the pressing block 2 and the conductive base 1 are squeezed simultaneously, improving the stability of the main line and the branch line. At the same time, the end of the branch line and the branch line body are at the highest point of the other cavity of the conductive base 1, making the cavity of the conductive base 1 have resistance to the wire, further improving the stability of wire installation.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
