Abstract
Description
Technical Field
[0001] This utility model relates to the field of torque terminal technology, specifically a novel torque terminal. Background Technology
[0002] In fields such as power systems, industrial automation control, and rail transportation, stable circuit connections rely on the reliable performance of terminal blocks. Torque terminals, in particular, ensure the tightness of wire connections through preset torque values (preventing damage from over-tightening or poor contact due to under-tightening), making them a key component in high-reliability scenarios. In practical applications, a single circuit often requires multiple connection nodes (such as branching or busbar scenarios). Therefore, using multiple torque terminals in series is a common configuration—usually, several terminals are fixed side-by-side using DIN rails (such as DIN rails) to form a terminal block, enabling centralized connection and management of multiple sets of wires.
[0003] Existing series-connected torque terminal blocks are mostly designed with "compactness" in mind, resulting in significant limitations in their structural features and installation methods: spacing lacks specific design, and wire arrangement and electromagnetic compatibility are poor. Traditional series terminals are mostly installed in a "no-spacing, close-proximity" manner, meaning adjacent terminal bodies are directly attached (or with only a tiny gap of 1-2mm), without independent spacing separation structures. When series terminals need to connect different types of wires (such as high-voltage wires and low-voltage signal wires), the tight spacing can cause electromagnetic signals generated by the high-voltage wires to interfere with the low-voltage signals, especially in precision control circuits (such as PLC control systems), easily leading to signal distortion. Utility Model Content
[0004] This invention provides a novel torque terminal block to solve the problems of existing terminals lacking specialized spacing design and having poor wire arrangement and electromagnetic compatibility.
[0005] This utility model provides the following technical solution: a novel torque terminal block, comprising a first terminal block housing assembly, and further comprising:
[0006] A cavity is provided on one side of the first terminal housing assembly, and an adjustment mechanism is slidably connected inside the cavity. The adjustment mechanism includes a telescopic rod and a positioning bolt.
[0007] A second terminal housing assembly is provided at one end of the telescopic rod. The first and second terminal housing assemblies are provided with a protective mechanism inside. The protective mechanism includes a protective inner tube and a locking screw.
[0008] As a preferred technical solution of this utility model, the telescopic rod is slidably connected to the inside of the cavity, and both the cavity and the telescopic rod are provided with a number of threaded holes, one of which is threadedly connected to a positioning bolt.
[0009] As a preferred embodiment of this utility model, the protective inner tube is fixedly connected to the inside of the first terminal housing assembly and the second terminal housing assembly. The top of the protective inner tube is provided with a threaded hole, and a locking screw is threaded into the inside of the threaded hole.
[0010] As a preferred technical solution of this utility model, a positioning semi-annular groove is provided on one side of both the first terminal housing assembly and the second terminal housing assembly, and a connecting semi-arc ring is hinged to one side of the positioning semi-annular groove.
[0011] As a preferred embodiment of this utility model, both the connecting semi-circular ring and the positioning semi-circular groove are fixedly connected with extrusion blocks, and the extrusion blocks are made of silicone.
[0012] As a preferred technical solution of this utility model, the surface of the connecting semi-circular ring is provided with a threaded hole, and the threaded hole is internally connected with a threaded column.
[0013] As a preferred embodiment of this utility model, a positioning post is attached to one side of the extrusion block, and the positioning post is inserted into the sealed space formed by the positioning semi-annular groove and the connecting semi-arc ring.
[0014] As a preferred embodiment of this utility model, the bottom of the positioning column is fixedly connected to a base, and the surface of the base is provided with threaded rods.
[0015] Compared with the prior art, this utility model provides a novel torque terminal block, which has the following beneficial effects:
[0016] 1. This new type of torque terminal block, through the setting of the adjustment mechanism, when different types of wires (such as high-voltage wires and low-voltage signal wires) need to be connected in series, in order to avoid the electromagnetic signals generated by the high-voltage wires from interfering with the low-voltage signals, the telescopic rod can be pulled to move inside the cavity. After it is moved to a suitable position, the telescopic rod and the threaded hole set on the surface of the cavity form a passage. Then, the telescopic rod is limited and fixed by the positioning bolt. In this way, when installing high-voltage wires and low-voltage signal wires, the problem of electromagnetic signal interference can be effectively avoided, and the compatibility of the equipment can be improved.
[0017] 2. This new type of torque terminal block, through the setting of a protective mechanism, protects the installed wires during use. Therefore, protective inner tubes are set inside both the first terminal block housing and the second terminal block housing. The wires are inserted into the protective inner tubes, and then the locking screw at the top of the protective inner tubes is turned to securely limit the wires, preventing the wires from shifting due to shaking or pulling during subsequent use, thereby providing a protective guarantee for the stable connection between the wires and the terminals.

[0028] In this embodiment, when different types of wires (such as high-voltage wires and low-voltage signal wires) need to be connected in series terminals, in order to avoid the electromagnetic signals generated by the high-voltage wires interfering with the low-voltage signals, the telescopic rod 201 can be pulled to move inside the cavity. After it moves to a suitable position, the telescopic rod 201 and the threaded hole on the surface of the cavity form a passage. Then, the positioning bolt 202 is used to limit and fix the telescopic rod 201.
[0029] Specifically, the protective inner tube 401 is fixedly connected to the inside of the first terminal housing assembly 1 and the second terminal housing assembly 3. The top of the protective inner tube 401 is provided with a threaded hole, and a locking screw 402 is threadedly connected inside the threaded hole.
[0030] In this embodiment, in order to protect the installation wires during use, a protective inner tube 401 is provided inside both the first terminal housing assembly 1 and the second terminal housing assembly 3. The wire is inserted into the protective inner tube 401, and then the locking screw 402 at the top of the protective inner tube 401 is rotated to securely limit the wire.
[0031] Specifically, a positioning semi-annular groove is provided on one side of both the first terminal housing assembly 1 and the second terminal housing assembly 3, and a connecting semi-arc ring 5 is hinged to one side of the positioning semi-annular groove.
[0032] In this embodiment, the arc-shaped space formed by the positioning semi-arc groove and the connecting semi-arc ring 5 facilitates the support and fixation of the first terminal housing assembly 1 and the second terminal housing assembly 3.
[0033] Specifically, extrusion blocks 6 are fixedly connected inside both the connecting semi-circular ring 5 and the positioning semi-circular groove. The extrusion blocks 6 are made of silicone.
[0034] Specifically, a threaded hole is provided on the surface of the connecting semi-circular ring 5, and a threaded post 7 is connected to the inside of the threaded hole.

[0037] Specifically, the bottom of the positioning post 8 is fixedly connected to a base 9, and the surface of the base 9 is provided with a threaded rod 10.
[0038] The working principle and usage process of this utility model are as follows: When different types of wires (such as high-voltage wires and low-voltage signal wires) need to be connected in series terminals, in order to avoid the electromagnetic signals generated by the high-voltage wires from interfering with the low-voltage signals, the telescopic rod 201 can be pulled to move inside the cavity.
