Terminal block quick wiring device based on characteristic test and use method thereof

Abstract

The invention relates to a terminal block quick wiring device based on characteristic test. The device comprises a wiring board screwed on a circuit breaker terminal block. A number of through holes one-to-one corresponding to wiring terminals on the terminal block are arranged in the wiring board. A number of telescopic connectors in the through holes are arranged on the wiring board. Each telescopic connector comprises a copper connector. The bottom of each copper connector passes through a through hole and is screwed with a supporting insulating sleeve. A conductive head is arranged on thebottom of each supporting insulating sleeve. A conductive copper spring is arranged between the top of each conductive head and the bottom of each copper connector. The terminal block quick wiring device based on characteristic test has a simple structure and can realize quick wiring.

Description

technical field [0001] The invention relates to a quick wiring device for a terminal block based on a characteristic test and a method for using the same. Background technique [0002] When performing the mechanical characteristics of the circuit breaker, 10 test wires need to be connected to the terminal block of the mechanism box. First, check the secondary wiring drawing of the circuit breaker, carefully identify and find out the 10 terminal numbers to be connected, and then use a screwdriver to remove 10 For the screws corresponding to the terminal numbers, every time you remove them, you have to face up to the terminal numbers horizontally to avoid dislocation and remove the wrong screws. At the same time, you need to remove the original wiring on some terminals, then insert the test line connector, and then use a screwdriver to tighten the screws. After completing the characteristic test, use a screwdriver to loosen 10 screws, restore the original wiring, and finally t...

Problems solved by technology

[0003] In mass production in the workshop, this method is a waste of time, and it may also be due to personnel mistakes to insert the wrong terminal block, poor maintenance quality and low efficiency: (1) Every time the wiring is tested for mechanical characteristics, it is necessary to search for the secondary wiring of the circuit breaker Drawings, even skilled workers have to check the secondary wiring drawings for confirmation after wiring, which is time-consuming, labor-intensive, and inefficient; (2) It takes some time for unskilled testers to check the secondary wiring diagrams , or even find the wrong terminal number; (3) After finding the correct terminal number, because each terminal is closely connected and the wiring row is small, it is easy to misplace and install the wrong connector, and each time it needs to be viewed horizontally The terminal number will not be connected to the wrong terminal number after multiple confirmations; (4) The original wiring on the terminal must be removed during the disassembly process. (5) When restoring the original wiring of the circuit breaker, there is also the possibility of incorrect wiring inside the circuit breaker due to misplaced installation. After the characteristic test is completed, the secondary wiring inside the circuit breaker will not be checked again. So that unqualified circuit breakers leave the factory or put into operation; (6) Every time you disassemble and assemble the wiring, you need to use a screwdriver to tighten it, and at the same time, it is possible that the secondary wiring of the circuit breaker is falsely connected because it is not fastened in place during restoration; (7) Since the workshop is produced in batches, the original method wastes time, the process is complicated, and the maintenance quality and efficiency are not good; (8) Frequent use of screwdrivers to disassemble the screws on the terminal block or improper force can easily lead to terminal block failure. The screws on the terminal block are slippery, while the screws on the terminal block are embedded inside the terminal block. After the screw is damaged, the entire terminal piece needs to be replaced, which is extremely inconvenient.
