AI Technical Summary
Existing power connectors are prone to wire detachment due to loose bolts during long-term use, affecting connection stability.
The design employs a limit block and a telescopic spring. By pushing the bolt, the clamping block is raised and lowered, achieving multiple limit fixation of the wire and preventing the bolt from loosening and falling off.
This effectively prevents wires from falling off due to loose bolts during long-term use, ensuring the stability and reliability of the connection.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transmission technology, specifically to a power connector that prevents detachment. Background Technology
[0002] Power connectors are key components in power systems used to connect, distribute, and transmit electrical energy. They ensure that current can be safely, stably, and efficiently transmitted from the power source to various electrical devices. Through mechanical structures, power connectors are used to connect multiple wires together to achieve the distribution and transmission of electrical energy.
[0003] During the design process of this utility model, the following problems were discovered in the existing technology:
[0004] When connecting wires, most existing connectors use bolts to tighten the two wires for a secure connection. After prolonged use, the bolt threads at the connection point can loosen, leading to wire detachment, poor contact, and affecting normal operation. Utility Model Content
[0005] The purpose of this utility model is to provide an anti-detachment power connector to solve the problem of connectors easily detaching after long-term use, as mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-detachment power connector, comprising a body, a push bolt at the upper end of the body, a clamping block at the bottom of the push bolt, an elastic block at the bottom of the clamping block, a limit block on one side of the elastic block, a limit rod on the inner wall of the elastic block, and a telescopic spring on one side of the limit rod.
[0007] More preferably, a fixing bolt is provided on one side of the push bolt, a fixing block is installed on one side of the machine body, a wire inlet hole is provided at one end of the machine body, a clip is provided on one side of the wire inlet hole, and an anti-slip pad is installed on the upper end of the clip.
[0008] In a further preferred embodiment, the clamping block forms a lifting structure by pushing bolts.
[0009] More preferably, the elastic blocks are evenly arranged along the bottom outer surface of the clamping block.
[0010] More preferably, the limiting rods are symmetrically installed about the transverse centerline of the clamping block.
[0011] More preferably, the limiting block is formed into an elastic structure by a telescopic spring.
[0012] More preferably, the clips are symmetrically installed about the transverse centerline of the body.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] By adding limit blocks and telescopic springs, when wiring the equipment, rotating the push bolt causes the push bolt to move the limit block up and down, thereby clamping and limiting the wire. Then, the wire is inserted into the clamp, which provides multiple limits and fixation for the wire, preventing individual bolts from loosening and falling off during use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 4 This utility model provides a technical solution: an anti-detachment power connector, including a body 1, a push bolt 2 at the upper end of the body 1, a clamping block 201 at the bottom of the push bolt 2, an elastic block 202 installed at the bottom of the clamping block 201, a limit block 203 installed on one side of the elastic block 202, a limit rod 204 on the inner wall of the elastic block 202, and a telescopic spring 205 on one side of the limit rod 204.
[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a fixing bolt 3 is provided on one side of the push bolt 2, a fixing block 4 is installed on one side of the body 1, a wire inlet hole 5 is provided at one end of the body 1, a clip 6 is provided on one side of the wire inlet hole 5, and an anti-slip pad 7 is installed on the upper end of the clip 6.
[0023] In this embodiment, as Figure 2 As shown, the clamping block 201 forms a lifting structure by pushing the bolt 2.
[0024] In this embodiment, as Figure 2 As shown, the elastic blocks 202 are evenly arranged along the bottom outer surface of the clamping block 201.
[0025] In this embodiment, as Figure 2 As shown, the limiting rods 204 are symmetrically installed about the transverse centerline of the clamping block 201.
[0026] In this embodiment, as Figure 2 As shown, the limiting block 203 forms an elastic structure through the telescopic spring 205.
[0027] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the clips 6 are symmetrically installed about the transverse centerline of the body 1.
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the anti-detachment power connector operates as follows during use:
[0029] First, fix the fixing block 4 in the desired installation location. Then, insert the wires to be connected into the body 1. Tighten the two wires by rotating the fixing bolt 3 to secure the connection. Next, rotate and push the bolt 2 to extend and retract the clamping block 201 to hold the wires. The elastic block 202 at the bottom of the clamping block 201 prevents damage to the wires when clamped. Then, insert the wires into the clip 6 to further clamp and secure the wires. By clamping and securing the wires multiple times, the wires are prevented from falling off due to loosening of individual bolts during long-term use of the equipment.
