Relay mounting structure of electrical junction box

Abstract

The invention discloses a relay mounting structure of an electrical junction box. The structure comprises a relay shell and a relay mounting mechanism. The relay mounting mechanism comprises a fixingshell, an adjusting assembly and a pair of clamping assemblies. A trapezoidal cavity is formed in the fixing shell, sliding grooves are formed in the positions, at the two ends of one side of the bottom face of the trapezoidal cavity, of the fixing shell in a penetrating mode, the adjusting assembly is arranged in the trapezoidal cavity, and the adjusting assembly comprises a screw rod, a rotatingwheel, an I-shaped sliding block, an internal thread sliding block and a hinge rod. An operator only needs to rotate the screw rod to enable the internal thread sliding block to move left and right on the screw rod, and the two H-shaped sliding blocks can be pushed to move oppositely or relatively through the hinge rod. Therefore, the distance between the two clamping assemblies is adjusted, theclamping assemblies are clamped in the metal plate mounting holes, the problem that the automobile relay is inconvenient to mount and dismount in a closed space is solved, and the production efficiency and quality of automobile assembly are improved.

Description

technical field [0001] The invention relates to the technical field of relay installation structures, in particular to a relay installation structure of an electrical junction box. Background technique [0002] Relays are widely used components in automobiles. Some relays are directly fixed in the relay box, and some relays need to be fixed separately. The relays fixed separately in the prior art are generally fastened to the automobile sheet metal by bolts passing through the bolt holes reserved on the relay housing. Separately installed relays are basically assembled on the sheet metal in the cab for dustproof and waterproof purposes. A circular hole is often opened in the sheet metal, and the mounting bolts are tightened with a socket or wrench. In order to make the vehicle look beautiful and the customer cannot see the relay, the relay is basically installed in the space under the instrument panel. If there is a problem with the circuit, the relay needs to be removed fo...

AI Technical Summary

Problems solved by technology

In order to make the vehicle look beautiful, the customer cannot see the relay. The relay is basically installed in the space under the instrument panel. There is no space for a wrench, let alone the space for turning the wrench, so to remove the relay, some other parts need to be disassembled to have space to remove the relay with tools, and some parts may be disassembled and reinstalled. There are some damages, such as the invention patent authorized on June 1, 2018 entitled "An Automobile Relay Installation Structure", its application number is; The sheet metal is clamped and fixed, which solves the problem of inconvenient disassembly of the automotive relay in a closed space, but when it is installed, it needs to use a large force to squeeze the force adjustment part inwards, so that the limit and fixed part can be snapped into the car sheet metal Inside the hole, and can only be fixed on sheet metal of certain thicknesses
