Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal block technology, specifically to a misaligned high-voltage terminal block. Background Technology
[0002] Terminal blocks are components that electronic engineers frequently encounter. Their function is quite simple: as conventional components that transmit electrical signals through metal parts, they typically require a stable connection between the two ends to ensure reliable signal transmission and enable the circuit to perform its intended function. Terminal blocks are widely used in various wiring connections, such as connecting wires or cables.
[0003] The existing terminal block structure is relatively complex and the design is unreasonable. When installing cables, they need to be stranded and the terminal blocks are installed on the stranded cables. The cables are installed in a staggered manner. When fixing the terminal blocks and cables, terminal pliers are usually used to deform the terminals and tightly wrap the cable conductors. After deformation, the connection between the terminals and the cables is not tight, which can easily cause the cables to fall off after long-term use. In addition, there is a large gap between the deformed terminals and the cables. Utility Model Content
[0004] The purpose of this utility model is to provide a misaligned high-voltage terminal block, which has the advantages of simple structure, reasonable design, good tightness between the terminal and the cable, and small gap, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a staggered wiring type high voltage terminal block, comprising: a first connecting mechanism for connecting cables, the first connecting mechanism comprising a long column, wherein the long column has a plug slot for cable insertion, and a plurality of deformation grooves are equally spaced in a ring array around its axis. The second connecting mechanism is used to connect the power distribution cabinet. The second connecting mechanism is located at one end of the first connecting mechanism, and the second connecting mechanism includes a connecting block one. A connecting block two is provided at the end of the connecting block one away from the first connecting mechanism. A connecting hole is opened in the connecting block two.
[0006] Preferably, the long column is provided with an anti-slip part one and an anti-slip part two, wherein both the anti-slip part one and the anti-slip part two are composed of a plurality of anti-slip strips, which are arranged in a ring and perpendicular to the direction of cable travel.
[0007] Preferably, there are six deformation grooves, and each deformation groove is V-shaped.
[0008] Preferably, the end of the insertion slot near the second connecting mechanism is provided with an anti-detachment groove, which is shaped like a frustum.
[0009] Preferably, the diameter of the anti-detachment groove gradually increases from one end near the insertion groove toward the other end, and the connection between the anti-detachment groove and the insertion groove is provided with an arc-shaped protective surface.
[0010] Preferably, the first connecting block has two symmetrically arranged clearance surfaces, and the end of the second connecting block away from the first connecting block is arranged in an arc shape.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a misaligned high-voltage terminal block, which includes a first connecting mechanism and a second connecting mechanism. The overall structure is simple and reasonably designed. After the cable is inserted into the plug slot, the terminal is squeezed by the terminal clamp to compress the terminal into a hexagonal shape. When the terminal is deformed, several deformation grooves set in the long column reduce the gap between the terminal and the cable after deformation. The anti-slip part one and anti-slip part two set on the plug slot can increase the friction between the terminal and the cable after the terminal is deformed. The anti-disengagement groove set on the plug slot allows the cable to be embedded when the end expands under pressure, thereby increasing the connection area between the cable and the terminal.
