Problems solved by technology

Through actual use, it is found that when the current collector passes through the expansion joint with expansion joints, the collector shoe is affected by the expansion joint, 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 no

Abstract

The invention relates to a jointless telescopic connector with contact rails. The jointless telescopic connector with the contact rails comprises two contact rail segments, a limiting guide body, a contact surface slide block and an electrical conductor, wherein the two contact rail segments are in connecting fit with sliding clearances through the limiting guide body; at least one contact surface slide block is arranged on the limiting guide body or substrates of the contact rail segments; the external contact surface of the contact surface slide block and the external contact surfaces of the contact rail segments are located on the same working surface; the contact surface slide block partially or completely covers a telescopic gap between the two contact rail segments; at least one edge of the contact surface slide block is a bevel edge; the included angle of the sideline of the bevel edge and the telescopic direction of the contact rail segments is smaller than 90 degrees; when the two contact rail segments displace in the length direction to cause a change of the telescopic gap, the contact surface slide block correspondingly displaces along the direction vertical to the telescopic direction of the contact rail segments to adapt to the change of the telescopic gap on the contact working surface; and meanwhile, at least one electrical conductor is connected with the limiting guide body or/and the two contact rail segments to achieve electrical conduction.

Description

technical field [0001] The invention relates to a telescopic connector for rail transit contact rail system. Background technique [0002] The main function of this type of telescopic connector is to compensate the length change of the contact rail due to temperature and mechanical displacement and the electrical connection of the contact rail. For the telescopic connector described in the invention patent specification of China Authorized Notice No. CN102427172B, the currently used telescopic connector has better solved the thermal expansion and contraction of the contact rail system, mechanical displacement, current transmission, elimination of adjacency force and expansion and contraction. However, the solution and product still have design flaws, the main flaws are described as follows: [0003] In the prior art, measures taken by this type of telescopic connector to deal with length changes caused by thermal expansion and contraction of the contact rail and mechanical ...
