Description

An anti-extrusion connector terminal

technical field

The invention relates to the technical field of electrical connectors, in particular to an anti-extrusion connector terminal.

Background technique

Current capacity is the basic index of electrical connectors. In order to meet the temperature rise requirements of UL tests, contact reliability is indispensable. Usually, for small current terminals with a current below 1A, elastic contacts can meet the requirements of the terminals. Contact reliability. For terminals with a current greater than 1A, fasteners are generally used to connect them. Because of their advantages of uniform specifications, strong adaptability, easy standardization, and simple and convenient operation, they are widely used in electrical engineering. The terminal block plays the role of connecting the cable and the metal conductor, especially in the working state of high current, in order to reduce the power loss of the system, it is required to choose a conductor material with good conductivity to make the metal conductor, such as: brass, copper, Nickel copper, beryllium copper, etc., especially brass and red copper, are widely used due to their high cost performance; the problem is that because copper has low hardness and is not resistant to wear, fasteners are usually made of steel. When bolts or screws are fastened to copper metal conductors, the copper metal conductors are often deformed or partially damaged, reducing the repeated use rate of the metal conductors.

Contents of the invention

The purpose of the present invention is to provide an anti-extrusion connector terminal for the deficiencies of the prior art. The present invention adopts the structure of adding a gasket between the metal conductor and the locking screw, which not only ensures the metal conductor and the cable The electrical performance of the connection prevents the deformation and local damage of the metal conductor, improves the repeated use rate of the metal conductor, and improves the working reliability and service life of the connector terminal. the

The concrete technical scheme that realizes the object of the invention is:

An anti-extrusion connector terminal, which is characterized by square terminals, gaskets, metal conductors and locking screws. The through hole is vertically provided with a threaded hole penetrating the through hole, the gasket is a rectangular piece, at least one end of which is provided with a raised buckle, and the metal conductor is provided with at least one slot; the gasket is stacked on The top of the metal conductor, and the buckle is snapped into the card slot; the gasket and the metal conductor are passed through the hole of the square terminal, the locking screw is set in the threaded hole of the square terminal, and the end of the locking screw and the gasket touch the upper surface.

The invention adopts the structure of adding a gasket between the metal conductor and the locking screw, which not only ensures the electrical performance of the connection between the metal conductor and the cable, but also prevents local deformation and local damage of the metal conductor, and improves the repeated use rate of the metal conductor , Improve the reliability and service life of the connector terminals.

Detailed ways

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present invention includes a square terminal 1, a gasket 2, a metal conductor 3 and a locking screw 4. The through-hole 11 of Chinese font or " ten " is vertically provided with the threaded hole 12 that runs through through-hole 11, gasket 2 is a rectangular piece, and its at least one end is provided with protruding buckle 21, and metal conductor 3 is provided with at least There is a slot 31; the gasket 2 is stacked on the metal conductor 3, and the buckle 21 is snapped into the slot 31; the gasket 2 and the metal conductor 3 are passed through the hole 11 of the square terminal 1, The locking screw 4 is disposed in the threaded hole 12 of the square terminal 1 , and the end of the locking screw 4 touches the upper surface of the washer 2 .

the

The present invention is used like this:

The present invention includes a square terminal 1, a gasket 2, a metal conductor 3 and a locking screw 4. When in use, firstly, the gasket 2 is stacked on the metal conductor 3, and the buckle 21 on the gasket 2 is engaged with the In the slot 31 of the metal conductor 3, put the through hole 11 of the square terminal 1 on the position where the gasket 2 is installed on the metal conductor 3, and then put the square terminal 1 together with the metal conductor 3 into the insulating base, so that the square terminal Align the hole 11 of 1 with the cable hole in the insulating base, insert the cable 5 from the cable hole into the through hole 11 of the square terminal 1, and make the cable 5 between the metal conductor 3 and the through hole 11, and tighten the locking screw 4 , the end of the locking screw 4 compresses the washer 2, and the metal conductor 3 squeezes the cable 5 and the metal conductor 3 and fastens them in the square terminal 1, and the installation is completed. When disassembling, only need to loosen the locking screw 4, the cable 5 and the metal conductor 3 can be separated.

Due to the setting of the gasket 2 of the present invention, the end of the locking screw 4 does not directly touch the metal conductor 3 and the cable, and because the gasket 2 is selected from stainless steel or other metal materials with higher hardness, under the protection of the gasket 2, The metal conductor 3 is changed from the original point force to the surface force, which prevents the local deformation and local damage of the metal conductor, prolongs the service life of the metal conductor 3, achieves the purpose of repeated use, and ensures that the metal conductor 3 and Connection reliability of cable 5.

Since the end of the gasket 2 of the present invention is provided with at least one protruding buckle 21, during use, the gasket 2 is stacked on the metal conductor 3, and the buckle 21 is snapped into the slot 31, so that Just ensure that in the process of installing and connecting the cable 5, the gasket 2 will not fall off by itself, which not only facilitates construction, but also ensures the quality of the connection of the cable 5.

The invention has a simple manufacturing process and is suitable for standardized mass production, especially for metal conductors with high manufacturing costs, can be repeatedly installed and used, and has the advantages of convenient construction, safe and reliable connection, low manufacturing cost and good use effect.

Referring to FIG. 5 , the cable 5 of the present invention is connected to the metal conductor 3 in a "T" shape in use.

Referring to Fig. 6, the cable 5 of the present invention is connected to the metal conductor 3 in the shape of a "one" in use. the
