Description

Bus duct anti-theft connector

Technical Field

The invention relates to an electric connector, in particular to a bus duct connector; belongs to a power transmission and distribution device.

Background

The bus duct has the advantages of compact structure, convenient use, large carrying capacity and the like, and is widely applied to power transmission and distribution systems of large commercial squares, buildings and hospitals.

In the wiring construction process, each section of bus duct is connected through an electric connector. At present, a widely used electrical connector is generally composed of an insulating side plate positioned between two clamping plates, a plurality of insulating partition plates fixed with a conductive plate, and bolts for connecting and locking the clamping plates, the insulating side plate and the insulating partition plates; such as "CN 208256929U", "CN 210111545U", etc. These connectors, although relatively simple, are subject to the following drawbacks:

1) adopt a bolt to establish ties and lock, take place to warp or the thickness size leads to the clamp force inhomogeneous easily when the deviation appears in the generating line copper bar to cause the area of contact between current conducting plate and the generating line copper bar not enough, contact resistance increases, generates heat easily.

2) Because the generating line copper bar is located the both sides of bolt, need trompil on the current conducting plate, consequently not only the structure is more loose huge, and current conducting plate copper product consumption is big, with high costs, has also reduced the effective area of contact of current conducting plate moreover.

3) The current conducting plate is fixed in insulating barrier surface, does not fix a position it through the mode of adhesion, consequently is heated the back and then probably takes place to shift if there is exogenic action to cause with the lapped area reduction of generating line copper bar, contact resistance increase.

4) The bus copper bars on the two sides of the connector are not limited and guided, so that the connector is difficult to install, and the bus copper bars are easy to shake under the action of external force, so that potential safety hazards exist.

5) The connecting bolt is directly exposed on the surface of the clamping plate, so that the connecting bolt can be disassembled and stolen by using simple tools such as a common wrench and the like, and the anti-theft safety is poor.

It can be seen that the conventional busway connector has the above-mentioned many drawbacks, and needs to be improved.

Compared with the prior art, the invention has the following advantages due to the adoption of the technical scheme:

1) two bolts are adopted for connection and locking, so that the bus copper bar is more uniformly stressed and is more stably and reliably contacted with the current conducting plate.

2) The bus copper bar is positioned between the two bolts, so that holes do not need to be formed in the current conducting plate; the processing technology of the current-conducting plate is simplified, the conductive copper material is saved, and the effective contact area of the current-conducting plate is increased.

3) The current conducting plate is inlaid in the T-shaped groove, and even if the current conducting plate is not displaced under the action of external force, enough lap joint area and contact resistance can be guaranteed to be reserved between the current conducting plate and the bus copper bar.

4) The T-shaped groove can also guide and limit the bus copper bar, so that the bus copper bar is convenient to install and can be prevented from shaking under the action of external force, and the potential safety hazard that the bus copper bar is dislocated and separated is eliminated.

5) Because set up location strip and first positioning groove on insulating barrier, consequently can guarantee the accurate positioning between each insulating barrier and between insulating sideboard and the insulating barrier, but also can avoid the installation direction mistake (for example T-slot one end notch is downward) and cause the current conducting plate to deviate from, improve female installation connection efficiency who arranges.

6) A limiting groove formed by two rib plates is added on the back surface of the clamping plate, a groove cover locked by a buckle structure is added on the limiting groove, and the connector is shielded by a cover plate fixed on the protective cover; therefore, the bolt head and the nut can be hidden in the limiting groove, so that the bolt cannot be disassembled by using simple tools such as a common wrench, the groove cover cannot be pulled out from the upper part or the lower part of the connector, and the anti-theft safety is good.
