Utility model content
The purpose of this utility model does not have aiming at above-mentioned existing breaker body two sidewalls with terminal cover or partition
Forming reliable and stable connection relationship and being easy is that electrical discharge arc is excessive or even burn out the technological deficiency of breaker, and it is disconnected to provide a kind of low pressure
Road device terminal insulative structure-improved, terminal cover or partition position limiting structure are added on two lateral wall of breaker body, makes terminal
Two lateral walls of cover or partition and breaker body also securely connect, and avoid electrical discharge arc in the breaker course of work and puncture
The risk of terminal cover or partition, the arc protection for improving breaker pierce through the ability of insulation.
Technical solution
In order to achieve the above technical purposes, a kind of low-voltage circuit breaker terminal insulative structure-improved provided by the utility model,
It includes breaker body, is equipped with several wiring mounting grooves one at the terminal connections at the breaker body both ends side by side, described
Several wiring mounting grooves one are located at the cell wall on the inside of the breaker body equipped with link slot one, breaker terminals cover or every
Connection convex ribs item one corresponding with the link slot one is provided in the corresponding sidewall end of plate, the connection convex ribs item one is inserted into
In corresponding link slot one, it is characterised in that: the both sides lateral wall of the breaker body is broken using position limiting structure one with described
Road device terminal cover or the corresponding side wall connection of partition.
Further, the link slot two being arranged on the both sides lateral wall of the position limiting structure one including the breaker body,
Connection convex ribs item two corresponding with the link slot two is provided on the breaker terminals cover or the corresponding sidewall end of partition,
The connection convex ribs item two is inserted into corresponding link slot two.
Further, the link slot one is arc groove, and the connection convex ribs item one is arc convex ribs item.
Further, the link slot two is arc groove, and the connection convex ribs item two is arc convex ribs item.
Beneficial effect
A kind of low-voltage circuit breaker terminal insulative structure-improved provided by the utility model, on two lateral wall of breaker body
Adding breaker terminals cover, perhaps partition position limiting structure makes two lateral walls of breaker terminals cover or partition and breaker body
Also securely connection avoids the risk of electrical discharge arc breakdown breaker terminals cover or partition in the breaker course of work, improves
The arc protection of breaker pierces through the ability of insulation, while adding position limiting structure on the lateral wall of breaker body both sides being capable of benefit
It is connected side by side in multiple rows of breaker body.
