Description

Socket of plug-in box for intensive bus duct

Technical Field

The utility model relates to a switch technical field specifically is an intensive bus duct jack box socket.

Background

The conductive part area of contact of the internal inserted sheet of plug and socket ubiquitous bus duct jack box socket that circulates in the market is less, and the resilience force of inserted sheet is not enough, runs into great electric current and often leads to the contact point of plug and inserted sheet to generate heat, brings the potential safety hazard.

In the prior art, the elasticity of copper is low, the plugging times of a plug and a plug-in unit are more, the contact point of the plug and an inner insertion sheet is loosened, the current passing performance is reduced, and a fire disaster easily occurs.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an intensive bus duct jack box socket to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an intensive bus duct jack box socket, includes the socket, spacing hole has been seted up on the socket surface, five have been seted up at least in spacing hole, spacing downthehole line board is inserted, the screw hole is seted up to line board lower part, the socket up end is located and installs the protecting tube around spacing hole, the first locating hole that runs through the protecting tube is seted up to the protecting tube lateral wall, spacing groove has been seted up in the protecting tube, the second locating hole that runs through the line board is seted up on line board upper portion, the line board lower extreme has been seted up the wire casing, line board upper end welded mounting has the inserted sheet, the inserted sheet outside is equipped with insulating steel spring, insulating steel spring lower extreme welded mounting is in the.

Preferably, the length of the groove width and the groove length of the limiting groove are both larger than the hole width and the hole length of the limiting hole.

Preferably, there is not fixed connection between insulating steel sheet spring and the inserted sheet, insulating steel sheet spring closely laminates with the outer wall of inserted sheet.

Preferably, the surface of the outer side wall of the insert is coated with insulating paint.

Preferably, the first positioning hole and the second positioning hole are equal in size.

Preferably, the threaded hole penetrates through the wire groove.

Compared with the prior art, the beneficial effects of the utility model are that: this intensive bus duct jack box socket, this device inserted sheet is copper material, steel sheet spring through the outside parcel looks isostructure at copper conductor, can increase the area of contact of inserted sheet and plug wantonly, and can not lead to the elasticity reduction of copper conductor, thereby let the electric conductivity increase between plug and the inserted sheet, increase the electric conduction volume, plug repeatedly, also can not arouse not hard up, and this device line board lower extreme has seted up the wire casing, can guarantee through the wire casing that the area of contact between line board and the intensive line row strengthens, effectively prevented because of the less a large amount of heats that produce of area of contact between line board and the line row, avoid causing the potential safety hazard.
