Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a cable multi-port connector. Background Technology

[0002] With rapid economic development, the demand for electricity is increasing, and overhead transmission lines are also developing rapidly. High-voltage transmission lines are channels connecting substations and transmitting electricity, and are an important part of the power grid. A large number of high-voltage transmission lines need to be connected in a T-shape, connecting the main line and branch line of the same voltage level at the line crossing through a multi-pass clamp, thereby enabling the simultaneous supply of power from one main line to one or more branch lines.

[0003] The shortcomings of existing technology:

[0004] Currently, when making T-type connections, the most commonly used products are C-type clamps, aluminum parallel groove clamps, bolt-type and compression-type T-type clamps. Although these products can achieve T-type connections, there are too many specifications for C-type clamps, making selection and wiring complicated. Often, due to the mismatch between the outer diameter of the conductor and the product, the clamps are either too loose after installation, resulting in poor contact, or too tight, causing them to slowly loosen and lead to circuit faults. Aluminum parallel groove clamps lack insulation protection, leaving the product and conductors exposed to the atmosphere. Over time, they will slowly oxidize and corrode due to contact with air, reducing the product's lifespan and easily leading to electrical safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a multi-port cable connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable multi-port connector, the connector comprising a clamp body and an insulating protective component wrapped around the outside of the clamp body, the clamp body having a main cable mounting groove through which the main cable is installed in the installation direction of the main cable, a first bolt hole being provided on one side wall of the main cable mounting groove, the clamp body also having a branch cable mounting hole for installing branch cables, and a second bolt hole being provided on the side wall of the branch cable mounting hole.

[0007] Preferably, a locking groove is provided on the groove wall of the main line mounting groove near the bottom of the groove, and the locking groove is arranged opposite to the first bolt hole.

[0008] Preferably, the bottom of the locking groove is conical, and the bottom of the locking groove is provided with teeth.

[0009] Preferably, the insulating protective assembly includes an upper shell and a lower shell, wherein the upper shell and the lower shell are hinged to each other on one side wall that is close to each other.

[0010] Preferably, the upper shell and the lower shell are respectively provided with main line pipe openings and branch line pipe openings at the main line mounting groove and the branch line mounting hole, and a buckle is provided between the upper shell and the lower shell.

[0011] Preferably, both the upper and lower shells have support pieces inside that are provided along the outer contour of the clamp body for fixing the clamp body.

[0012] Preferably, torsion bolts for fixing the main cable and branch cable are installed at both the first bolt hole and the second bolt hole.

[0013] Preferably, the torque bolt has a fracture groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This cable multi-port connector has a main cable mounting groove extending through the clamp body in the direction of main cable installation. A first bolt hole is provided on one side wall of the main cable mounting groove. A branch cable mounting hole is provided below the main cable mounting groove and perpendicular to the main cable mounting groove. The branch cable mounting hole is used to install branch cables. A second bolt hole is provided on one side of the branch cable mounting hole. Torque bolts for fixing the main cable and branch cables are movably installed in the first bolt hole and the second bolt hole, respectively. The main cable is pressed against the inside of the main cable mounting groove by the torque bolts, and the branch cable is pressed against the inside of the branch cable mounting hole by the torque bolts. This improves the stability of the clamp body in fixing the cable and prevents poor contact and line faults due to the clamp body being installed too loosely.

The upper and lower shells are movably connected by a snap-fit ​​hinge and are mounted on the outside of the clamp body. The upper and lower shells are respectively provided with main line ports and branch line ports at the main line mounting slot and branch line mounting hole, respectively. The main line ports and branch line ports are connected by snap-fit ​​mechanisms, improving the connection stability between the upper and lower shells. The upper and lower shells prevent the product and wires from being exposed to the atmosphere for extended periods, thus preventing oxidation and corrosion, extending the product's lifespan, and reducing electrical safety hazards.

[0017] 3. This type of cable multi-port connector uses torque bolts to press the main cable into the main cable mounting groove and to press the branch cable into the branch cable mounting hole. The head of the torque bolt will break off from the groove to achieve the purpose of fixing the main cable. Attached Figure Description

[0026] Example

[0027] Please see Figure 1-3 As shown, this utility model provides a cable multi-port connector technical solution: the connector includes a clamp body 110 and an insulating protective component 120 installed on the outside of the clamp body 110. The insulating protective component 120 prevents the product and cable from being exposed to the atmospheric environment and causing oxidation, and reduces electrical safety hazards. The clamp body 110 has a main cable mounting groove 111 through it according to the installation direction of the main cable. A first bolt hole 112 is opened on one side wall of the main cable mounting groove 111. A branch line mounting hole 113 is provided below the main line mounting groove 111 and perpendicular to the main line mounting groove 111. The branch line mounting hole 113 is used to install the branch line cable. A second bolt hole 114 is provided on one side of the branch line mounting hole 113. Torque bolts 130 for fixing the main line cable and the branch line cable are movably installed in the first bolt hole 112 and the second bolt hole 114 respectively. The torque bolt 130 can be either an external hexagon or an internal hexagon to facilitate disassembly. The torque bolt 130 is provided with a fracture groove 131.

[0028] In use, after stripping the main cable, insert it into the main cable mounting slot 111 of the clamp body 110. Then, screw the torque bolt 130 into the first bolt hole 112. The torque bolt 130 secures the main cable against the locking slot 1111. When the torque bolt 130 is tightened to the set torque, the head of the torque bolt 130 will break off from the break groove 131 to achieve uniform torque. A locking groove 1111 is integrally formed on the groove wall of the main cable mounting slot 111 near the bottom of the slot. The locking groove 1111 is distributed opposite to the first bolt hole 112. The bottom of the 1111 groove is conical, and the bottom of the locking groove 1111 is provided with teeth 140 to increase the friction between the main line mounting groove 111 and the main line cable to improve the stability of the main line cable fixing. After stripping the wire of the branch cable to be connected to the main line cable, insert it into the branch line mounting hole 113. Then screw the torque bolt 130 into the second bolt hole 114. The torque bolt 130 is used to press the branch cable against the inside of the branch line mounting hole 113. After the torque bolt 130 is tightened to the set torque, the head of the torque bolt 130 is broken off to facilitate the installation of the insulation protection component 120.

[0029] The insulation protection assembly 120 includes an upper shell 121 and a lower shell 122. A snap-fit ​​hinge is integrally formed on the adjacent side wall of the upper shell 121 and the lower shell 122. The upper shell 121 and the lower shell 122 are installed on the outside of the clamp body 110. The upper shell 121 and the lower shell 122 are respectively formed with a main line port 124 and a branch line port 125 at the main line mounting groove 111 and the branch line mounting hole 113. The main line port 124 and the branch line port 125 are provided with buckles 126. The upper shell 121 and the lower shell 122 are engaged by the buckles 126 to improve the connection stability between the upper shell 121 and the lower shell 122.

[0030] During installation, the upper shell 121 and the lower shell 122 are detachably installed together via a snap-fit ​​hinge 123. The upper shell 121 and the lower shell 122 can rotate relative to each other via the snap-fit ​​hinge 123. The upper shell 121 and the lower shell 122 are then installed on the outside of the clamp body 110. The main line port 124 and the branch line port 125 correspond to the main line mounting groove 111 and the branch line mounting hole 113. The upper shell 121 and the lower shell 122 are integrally formed with support plates 150 for fixing the clamp body 110 along the outer contour of the clamp body 110, which improves the stability of the clamp body 110 installed inside the insulation protection component 120, thus completing the cable connection.

[0031] Working principle of this device:

[0032] In use, strip the main cable and insert it into the main cable mounting slot 111 of the clamp body 110. Then, screw the torque bolt 130 into the first bolt hole 112 on the side wall of the main cable mounting slot 111. The torque bolt 130 will hold the main cable in place in the locking slot 1111. When the main cable mounting slot 111 is tightened to the set torque, the head of the torque bolt 130 will break off from the break groove (the torque bolt can also be an internal hex bolt for easy disassembly). After stripping the branch cable to be connected to the main cable, insert it into the branch cable mounting hole 113 and tighten the torque bolt 130 in the second bolt hole 114 to the set torque, causing the bolt head to break off, which facilitates the installation of the insulation protection component. When installing the insulation protection assembly, the hinges of the upper shell 121 and the lower shell 122 are snapped together so that the upper shell 121 and the lower shell 122 can rotate relative to each other. Then the upper shell 121 and the lower shell 122 are installed on the outside of the clamp body 110. The upper shell 121 and the lower shell 122 are connected by multiple sets of snap fasteners 126.
