A multi-pin interface control cabinet chassis blind plug-in power-assisted handle mechanism

Abstract

The invention provides a multi-pin interface control cabinet case blind plug-in power-assisted handle mechanism, which includes a plug-in and pull-out handle mechanism with the same structure and symmetrically installed on the front panel of the multi-pin interface cabinet. The plug-in and pull out handle mechanism includes a handle, The knob assembly and the knob fixing pin are connected to the front panel of the multi-pin interface chassis by turning the handle. There are through holes on the front panel of the multi-pin interface chassis. The through holes correspond to the vertical beams of the control cabinet set on the multi-pin interface chassis. , one end of the knob assembly is installed on the upper end of the handle, and the other end of the knob assembly is set in the vertical beam of the control cabinet through the through hole. The knob assembly is provided with a knob fixing pin hole, and the upper end of the handle is provided with a handle that matches the knob fixing pin hole. The fixing pin hole position, the knob fixing pin passes through the handle fixing pin hole and the knob fixing pin hole, the handle and the knob assembly are fixed, and the blind insertion and removal with power is realized, which reduces the effect of manpower and improves the installation of the measurement and control circuit module and maintenance performance.

Description

technical field [0001] The invention relates to the field of measurement and control and communication equipment, in particular to a multi-pin interface control cabinet chassis blind plug-in power-assisted handle mechanism. Background technique [0002] The components in the measurement and control equipment and communication equipment often adopt the rear panel assembly structure. Due to the large number of connectors in this structure, the cables in the chassis / cabinet are dense and messy, and it is difficult to maintain; to solve this problem, use between two chassis The rear panel is directly plugged and assembled. This structure can cancel the interconnection line between the upper and lower measurement and control units; and can effectively shorten the routing distance of the signal and power interconnection lines, which can greatly improve the reliability of the signal and power supply. [0003] At present, the number of interconnecting pins on the connectors on the r...

Problems solved by technology

With such a large insertion force, if you want to interconnect or disengage the plug-in and socket, it will be difficult to insert and pull smoothly without using the plug-in and pull-out mechanism, and it is easy to damage the pins

[0004] Inside the control cabinet, the chassis are arranged in multiple layers. On the same floor, the two chassis are directly connected back to back through multi-pin connectors. Because the chassis are blocked by layers and back to back, the plug-ins and sockets on the rear panel cannot be seen at all. The connection situation, it is difficult to realize the plug-in
