A contact rail telescopic connector without expansion joints

Abstract

The invention discloses a contact rail telescopic connector without expansion joints, which is arranged between two adjacent sections of contact rails. The connector includes an A-end connecting seat and a B-end connecting seat, and the A-end connecting seat and The B-end connecting seats are respectively arranged at the ends of two adjacent contact rails, the right end face of the A-end connecting seat faces the left end face of the B-end connecting seat, and the upper right end of the A-end connecting seat An upper connecting rail is provided, and a lower connecting rail is provided at the lower part of the left end of the B-end connecting seat, and the upper connecting rail and the lower connecting rail are interlaced up and down and the upper connecting rail is located above the lower connecting rail, The lower end surface of the upper connecting rail is provided with a power receiving slider, and the upper end surface of the lower connecting rail is provided with a power receiving chute. The power receiving chute slides inside, so that the two contact rails always maintain electrical conduction.

Description

technical field [0001] The invention relates to the field of contact rail connectors, in particular to a contact rail telescopic connector without expansion joints. Background technique [0002] When installing the contact rail, due to the influence of thermal expansion and contraction, it is necessary to reserve expansion joints between adjacent contact rails. When the temperature of the rail body rises, the two sections of the rail body will elongate in the direction of the reserved expansion joint, and the The gap becomes smaller, and vice versa. Through actual use, it is found that when the current collector passes through the expansion joint with expansion joints, the collector sliding shoes are affected by the expansion joints. The larger the joint, the greater the impact, and the faster the speed, the more obvious the impact. From the normal plane contact state The attitude changes, and after completely passing the expansion joint, it returns to the normal plane cont...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a contact rail telescopic connector without expansion joints to solve the problem that in the prior art, the expansion joints are integral joints. The part of the flow device passing through the expansion joint is in a suspended state, and it is easy to have a slight impact with the docking contact rail after passing through the gap, making abnormal noise and may cause visible or potential damage
