Anti-drop type surge protector for plugging and unplugging 1U panel

Abstract

The invention discloses an anti-drop surge protector for plugging and unplugging a 1U panel. The anti-drop surge protector comprises a pressure-sensitive module assembly, a pressure-sensitive base assembly, a gas release module assembly and a gas release base assembly; the pressure-sensitive module assembly and the gas release module assembly are both correspondingly provided with mistaken installation prevention structures and disengagement prevention structures. The pressure-sensitive base assembly and the gas release base assembly are attached in parallel and are connected in a penetratingmanner through rivets; a bus bar is arranged between the pressure-sensitive base assembly and the gas release base assembly in a penetrating mode, and the bus bar is connected with a bus elastic piecewith the slope guiding function. A remote signaling serial connection assembly is arranged between the pressure-sensitive base assembly and the gas release base assembly in a penetrating manner, is used for connecting remote signaling signals of the pressure-sensitive module assembly and the gas release module assembly in series and is connected with a remote signaling terminal, and a warning area is further arranged on the pressure-sensitive module assembly and the gas release module assembly. The anti-drop surge protector is novel and compact in structure and small in required installationspace, and meets the installation height requirement of a plug-in frame power supply 1U case.

Description

technical field [0001] The invention relates to the field of surge protectors, in particular to a 1U panel plug-and-pull anti-off type surge protector. Background technique [0002] The surge protector is a protection device that provides safety protection for various electronic equipment, instruments and meters, and communication lines. Cutting off the power serves to protect the back-end equipment. [0003] At present, there are mainly two types of SPD structures in the communication market: rail-type SPDs and PCB-mounted SPDs. [0004] For the rail-type SPD, it can be used for installation in distribution boxes with unlimited space or for installation in power supply cabinets with subracks above 2U, and the demand for installation space is relatively large. [0005] For the PCB on-board SPD, it can be installed in a 1U-high sub-frame power supply case, but it must be soldered on the PCB power board and fixedly installed in the sub-frame power supply case, and the SPD ca...

Problems solved by technology

[0005] For the PCB on-board SPD, it can be installed in a 1U-high sub-frame power supply case, but it must be soldered on the PCB power board and fixedly installed in the sub-frame power supply case, and the SPD cannot be seen directly outside the case. , while the wiring is complicated and the material cost is high

[0006] And when the lightning protector fails, it is difficult to visually distinguish which phase is faulty; and when the lightning protector is damaged and needs to be repaired and replaced, it is necessary to cut off the power supply and open the box cover, and the entire PCB power main board is removed, which makes It is extremely inconvenient to maintain and replace, and the maintenance cost is extremely high
