AI Technical Summary

Technical Problem

The existing terminal blocks are prone to loosening during wiring, and the wires are not crimped evenly, resulting in frequent loose connections.

Method used

A terminal block is designed, comprising a housing, connecting copper busbars, pressure blocks, plug blocks, and a spring structure. Through the cooperation of the plug blocks and pressure blocks, stable crimping and quick disconnection of wires are achieved. The inclined surface of the plug blocks and the tooth and groove structure of the elastic plate ensure a tight connection of the wires.

Benefits of technology

It achieves full-contact crimping of wires to prevent loosening and supports quick wiring and disconnection operations, improving the reliability and efficiency of wiring.

Description

TECHNICAL FIELD

[0001] The utility model relates to a wiring terminal row. BACKGROUND

[0002] In the automatic control equipment, each electrical module needs to be connected to the power distribution cabinet through secondary wiring terminal, and the terminal row is pressed by a bolt when wiring, but the bolt of the terminal row often loosens, and the bolt and the stripped wire are gradually pressed when being twisted, which often causes the wire to branch and only part of the wire to be pressed, and the wire is loose for a long time. UTILITY MODEL CONTENTS

[0003] The utility model aims at solving the above-mentioned technical problems, and provides a wiring terminal row.

[0004] The above-mentioned purpose is realized by the following technical scheme:

[0005] A wiring terminal row, which comprises a box body, a connecting copper row fixed at the bottom of the box body, a middle rib plate and two side ribs in the box body, a spring connected between the middle rib plate and the pressing block, two openings provided at the top of the box body, and an insertion block inserted into each opening and pressed on the inclined surface of the pressing block.

[0006] The insertion block comprises a square block, an inclined surface provided on one side of the square block, two elastic plates fixed on the upper part of the square block, and an insertion tooth provided on each elastic plate.

[0007] The middle rib plate and the side rib plate are respectively provided with a tooth groove.

[0008] The pressing block is a copper pressing block. ADVANTAGEOUS EFFECTS

[0009] 1. When the stripped wire is inserted into the pressing block and the connecting copper row through the wire insertion port, the insertion block moves with the pressing block, so that the pressing block presses the wire tightly, the whole wire is pressed, the branching phenomenon is prevented, the connecting copper row is provided with a circular arc protrusion, the pressing block is provided with a circular arc groove matched with the circular arc protrusion, the wire is arc-shaped during the pressing, and the wire loosening phenomenon is prevented.

[0010] 2. The wire is pressed by the insertion block and the pressing block, the insertion block is pulled out during disassembly, the pressing block rebounds under the action of the spring, the pressing block is separated from the connecting copper row, the quick wiring and disconnection can be realized.

DETAILED DESCRIPTION

[0018] Referring to Figures 1-5 , a wiring terminal block, which is composed of a box body 3, the bottom of the box body is fixed with a connecting copper bar 5, both sides of the box body are provided with a cover plate 11, the inside of the box body is provided with a middle rib plate 7 and two side ribs 9, the middle rib plate is connected with a pressing block through a telescopic rod, the telescopic rod comprises an inner rod 17 and an outer tube 18, the outer tube is sleeved on the inner rod, the end of the inner rod is fixed with the pressing block, and the end of the outer tube is fixed with the middle rib plate, a spring 8 is connected between the middle rib plate and the pressing block, two openings 2 are formed in the top of the box body, a plug-in block 1 is inserted at each opening, and the plug-in block is pressed on the inclined slope of the pressing block.

[0019] The plug-in block comprises a square block, one side of the square block is provided with an inclined slope 10, and two elastic plates 12 are fixed on the upper portion of the square block, and each elastic plate is provided with a plug-in tooth 13.

[0020] The middle rib plate and the side rib plate are respectively provided with tooth grooves 14.

[0021] The pressing block is a copper pressing block.

[0022] Working principle: in use, referring to Figure 6, first hand pinch two elastic plate of plug, make it to bend in the middle, elastic plate of plug tooth will be out of the tooth groove, at this time will be out of plug, clamp plate is separated from the connecting copper bar under the action of spring, after separation, the wire 16 is stripped, then through the plug wire port 4 is inserted, make it fall on the connecting copper bar, then hand pinch two elastic plate of plug, plug through the opening is inserted, the inclined surface of plug and the inclined surface of plug contact, plug gradually move down, press the block to move to both sides, until the movement to the wire is pressed tightly after the stop, at this time, the plug cannot be pressed, release the elastic plate, the plug tooth of elastic plate will be inserted into the tooth groove, at this time, the wire is connected, the wire falls on the connecting copper bar, when the clamp is pressed, it will be pressed into the same shape as the connecting copper bar, because the connecting copper bar has a circular arc convex structure, the wire is pressed into a curved state, prevent the wire loose, when you need to remove the wire, just pinch two elastic plate of plug, make it to bend in the middle, elastic plate of plug tooth will be out of the tooth groove, at this time will be out of plug, clamp plate is separated from the connecting copper bar under the action of spring, the wire can be pulled out.
