Elevator bypass contact protection device

Abstract

An elevator bypass contact protection device comprises a base; the circuit board is arranged in the base; the welding pin terminal seat is arranged above the front part of the circuit board and is provided with three fixed blocks which are arranged in a shape like a Chinese character'pin ', and the rear end surfaces of the three fixed blocks are encircled to form a central accommodating groove; the six welding pin terminals are respectively arranged on the welding pin terminal seats; the three pairs of conductive assemblies are respectively arranged in the three fixing blocks on the welding pin terminal seat bottom plate; the adjusting wheel is arranged in the central accommodating groove; the rotating shaft is arranged in the adjusting wheel; the upper cover covers the welding pin terminal seat, and a positioning column is convexly arranged on one side of the top surface of the upper cover; the knob is arranged on the top surface of the upper cover, and three positioning holes matched with the positioning columns are formed in the rear part of the bottom surface of the knob at 90-degree intervals; and the electric connector is arranged at the rear part of the upper end surface of the circuit board. The knob lifting design is combined with the positioning structure, so that the knob is more accurate and convenient to operate and position, meanwhile, the structure is simple, the assembly process is simplified and improved, the working time is shortened, and the cost is reduced.

Description

technical field [0001] The invention relates to a circuit protection device, in particular to an elevator bypass contact protection device. Background technique [0002] There are many accidents caused by human operation. In order to ensure the normal operation and safe operation of the elevator, it is necessary to carry out debugging and safety inspection of the elevator. During the debugging process, when the staff conducts maintenance and debugging, often because of the short working hours, after the short-circuit device is installed Forgot to dismantle and cause elevator jamming, so to prevent and reduce the occurrence of elevator safety accidents, it is necessary to study the root cause of elevator failures, carefully study the use of elevator bypass devices, and see the occurrence of elevator short-circuit devices forgetting to disassemble. [0003] At present, the elevator bypass devices on the market are connected by electrical connectors to distinguish the short cir...

AI Technical Summary

Problems solved by technology

Such two-to-two docking requires multiple electrical connectors and complicated wire conduction, which causes great installation troubles for actual construction personnel, and the probability of misoperation will also increase a lot; the short-circuit device is to reduce the probability of safety accidents, but not Good operation increases the number of accidents
