Problems solved by technology

Defects of the fuse pressing equipment used in the prior art: 1. Use a mechanical manual pressing rod to press down the fuse. Because each person’s operating strength is different, there will be a risk of crushing the fuse due to excessive force; 2. It cannot be 100% mandatory Press down on the fuse, there is a risk of it falling off if the fuse is not inserted in place
Especially when the use environment of the fuse is the electronic circuit in the car, the pressure fuse equipment is far from meeting the requirements. anti-leakage fuse

Abstract

The invention provides a fuse pressing device comprising a fuse box, a die row cavity, a sliding track, a fuse disconnection indication device, and a pressure number display device. The fuse box includes a fuse element arranged between a line side guiding part and a load side guiding part. The die row cavity consists of a housing, a mechanical fixed rod and a double-control switch button. The sliding track is arranged at the bottom of the housing and the die row cavity can slide on the sliding track. The display device is connected with a fuse socket and the fuse element and is used for displaying a pressure value between the fuse socket and the fuse element. The die row cavity also includes an alarm terminal output end. When the fuse disconnection indication device is inserted into the fuse socket, the alarm terminal output end is connected with the pressure number display device and the fuse disconnection indication device. According to the device provided by the invention, with thedouble-control switch, the potential safety hazard is reduced.

Description

technical field [0001] The invention relates to the field of a circuit breaker, in particular to a press fuse device. Background technique [0002] As an overcurrent protection device, fuses are widely used to prevent circuit damage. Fuse terminals are commonly used to make an electrical connection between a power source and a circuit component or combination of components disposed in a circuit. Connecting one or more fusible links or elements, or fuse element devices, between the terminals of a fuse so that when the current through the fuse exceeds a predetermined limit, the fusible element melts, opening one or more circuits through the fuse, prevent damage to circuit components. [0003] In some applications, fuses are used not only to provide fused electrical connections, but also to make and break, or switch, the purpose of making or breaking one or more electrical connections. In this way, the circuit is made or interrupted by the conductive part of the fuse, thereb...
