Description

Technical Field

[0001] This utility model relates to the field of electrical materials, and in particular to a novel terminal block. Background Technology

[0002] Terminal blocks are common accessories for electrical connections. The use of terminal blocks makes the connection between wires faster and is safer than direct connection between wires.

[0003] However, existing terminal blocks generally suffer from the same drawback: the connection between wires and metal sheets is achieved by tightening bolts. After tightening, the bolts create stress, which can cause them to buckle over time, leading to loose connections, localized overheating, and even more serious electrical safety accidents. Furthermore, the bolt-tightening assembly method is relatively cumbersome, requiring at least two bolts to be tightened between two wires.

[0004] There is currently a lack of corresponding solutions to the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of terminal block that is easier to assemble and avoids loose wire connections during long-term use.

[0006] The equipment includes a junction box, which is the assembly base of this equipment;

[0007] On both sides of the junction box, there are through holes for threading wires through both ends.

[0008] A first elastic body is fixedly installed on the bottom surface of the inner cavity of the junction box, and the top of the first elastic body is a metal sheet;

[0009] An assembly slot is provided on the top of the junction box. A second elastic body is movably disposed in the assembly slot. A limit stop is provided on the upper part of the second elastic body based on the width of the slot. That is, when the second elastic body is pressed down, the limit stop assembly on its upper part elastically deforms, retracts inward and inserts into the assembly slot, enters the inner cavity of the junction box, and after entering the inner cavity of the junction box, it elastically restores its shape to prevent it from coming out of the assembly slot upward.

[0010] The bottom surface of the second elastomer is a metal sheet.

[0011] The effect achieved is that the two wires to be connected enter the wire through holes at both ends of the junction box, and the second elastic body is pressed down. Its limiting card assembly elastically deforms and retracts inward to insert into the assembly slot.

[0012] Based on the opposing compression of the first and second elastic bodies, the two wires are pressed together to achieve rapid connection.

[0013] The beneficial effects of this utility model are: it solves the problem that bolted terminals are prone to loose connections due to stress; it achieves continuous pressing of the metal core of the wire, avoiding loose connections during use. This improves electrical safety, and especially increases the efficiency of wire connection. Attached Figure Description

[0020] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] Reference Figure 1 , Figure 2 The present invention provides a novel terminal block, including a junction box 1, which is the assembly base of the device.

[0022] On both sides of the junction box 1, there are wire through holes 2 facing each other; the wire through holes 2 are used for threading wires through both ends;

[0023] A first elastic body 4 is fixedly installed on the bottom surface of the inner cavity of the junction box 1, and the top of the first elastic body 4 is a metal sheet 5.

[0024] An assembly slot is provided on the top of the junction box 1. A second elastic body 3 is movably disposed in the assembly slot. A limit stop is provided on the upper part of the second elastic body 3 based on the width of the slot. That is, when the second elastic body 3 is pressed down, the limit stop assembly on its upper part elastically deforms, retracts inward and inserts into the assembly slot, enters the inner cavity of the junction box 1, and after entering the inner cavity of the junction box 1, it elastically restores its shape to prevent it from coming out of the assembly slot upward.

[0025] The bottom surface of the second elastic body 3 is a metal sheet 5.

[0026] The effect achieved is that the two wires to be connected enter the wire through holes 2 at both ends of the junction box 1, and the second elastic body 3 is pressed down. Its limiting card assembly elastically deforms and retracts inward to insert into the assembly slot.

[0027] Based on the opposing compression of the first and second elastic bodies 3, the two wires are pressed together to achieve rapid connection.

[0028] In Example 1, the first elastic body 4 is one or more of a spring, spring sheet, or non-metallic elastic body.

[0029] This effect allows the metal sheet 5 on top to float upwards.

[0030] Example 2, refer to the accompanying drawings in the specification. Figure 1 or Figure 2 The first elastic body 4 is a multi-segment bent plastic structural component. The structural component includes a straight connecting segment that fits its metal sheet 5, and an oblique connecting segment that extends obliquely from both sides of the straight connecting segment to its lower outer side. A smoothly transitioned curved support connecting segment is also provided at the end of the oblique connecting segment.

[0031] The effect achieved is that, based on the elasticity of the inclined connecting section and the curved support connecting section, the wire is continuously pressed upward after assembly; and the use of the elastic connector made of plastic is safer.

[0032] Example 3, refer to the accompanying drawings in the specification. Figure 1 or Figure 2 The second elastic body 3 is a multi-segment bent plastic structural component, and its structural form is the same as that of the first elastic body 4, including a straight connecting segment, an oblique connecting segment and a curved support connecting segment connected in sequence.

[0033] Its orientation is symmetrical to that of the first elastic body 4;

[0034] A metal sheet 5 is fixedly installed on the bottom surface of its straight connecting section.

[0035] Furthermore, the assembly slot has beveled sides, with the slope corresponding to the slope of the inclined connecting section of the second elastic body 3.

[0036] Furthermore, a pressure rod 31 is integrally connected to the straight connecting section of the second elastic body 3, and a pressure plate 32 is provided on the pressure rod 31.

[0037] The effect achieved in this way is to facilitate assembly.
