End connection mechanism for embedded power supply system

Abstract

The invention discloses an end connection mechanism for an embedded power supply system. The end connection mechanism comprises two embedded supports and a bottom plate. Each embedded support comprises a body and a base; a conducting rail is arranged over the body of the embedded support. The embedded supports are fixedly mounted on the bottom plate through their bases. A connection box which can also be fixedly mounted on the bottom plate is disposed between the end embedded supports. The connection box is internally provided with a junction chamber. Two ends of the connection box are in connection fit with the adjacent ends of the embedded supports, respectively. The bottom plate is provided with cable holes admitting passage of cables. The end connection mechanism with the structure is simple in structure and convenient to mount, and the requirement for the level of installation of the embedded supports and the connection box is met; the embedded supports and the bottom plate are fixed by press-fitting of a mounting pressure plate, no structural damage of the embedded supports is required, the production process of the embedded supports is simpler, and the structural strength of the embedded supports can be improved.

Description

[0001] technical field [0002] The invention relates to a component for an urban rail transit power supply system, in particular to a terminal connection mechanism for an embedded power supply system. Background technique [0003] In the field of urban rail transit, the traditional power supply methods used by electric trains mainly include overhead catenary and contact rail power supply. The overhead catenary is installed along the line at a height of about 4-5m from the running rail, and the contact rail is installed along the line next to the line, generally about 200-400mm from the ground. The installation height of the overhead catenary is high, which is inconvenient for maintenance and has a certain impact on the landscape; the installation height of the contact rail is low, easy to install and maintain, and will not affect the landscape, but due to the low installation height of the contact rail, it may cause There is a risk of electric shock to personnel, so ra...

Problems solved by technology

However, the connection box and the ground-mounted bracket of the ground-mounted power supply system are directly installed on the road surface. In the prior art, there is no special connection structure for reliably overlapping the connection box and the ground-mounted support. Conventional means are used for connection, so that Poor connection quality, low precision, and many shifts and protrusions
