Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0014] Such as figure 1 with figure 2 As shown, an electrical protector 100 according to an embodiment of the present invention includes a housing 10 , a circuit board 20 inside the housing 10 , and a lightning protection wiring device 30 connected to the circuit board 20 . The lightning protection wiring device 30 includes a terminal base 31 , connectors, terminals 33 and nuts 34 . In this embodiment, the connecting piece is a connecting screw 32 . The terminal base 31 is directly welded on the circuit board 20 , and because the contact area between the terminal base 31 and the circuit board 20 is large, the we...

Abstract

The invention provides an electricity utilization protector which comprises an outer shell, a circuit board located in the outer shell and an anti-thunder wiring device connected with the circuit board. The anti-thunder wiring device comprises a terminal base welded to the circuit board, a wiring terminal located on the outer side of the outer shell, and a connection piece connecting the terminal base with the wiring terminal. The electricity utilization protector is compact in structure, capable of bearing impact of strong currents, large in installation intensity and capable of preventing accidental failures of an anti-thunder circuit.

Description

technical field [0001] The invention relates to a power protector, in particular to a lightning protection wiring device of the power protector. Background technique [0002] Electric protectors generally have a lightning protection circuit inside, so that they can protect the protector in the event of a lightning strike. In the lightning strike state, the lightning protection circuit will generate a large current, which needs to be led to the ground. The current method is to connect a wire on the internal circuit board, and then lead the wire out to the outside of the power protector to realize grounding. However, the welding strength between the wire and the circuit board is often not enough, and the instantaneous high current is also easy to burn the wire, resulting in the failure of the lightning protection circuit. [0003] In view of this, it is necessary to improve the existing power protector to solve the above problems. Contents of the invention [0004] The ob...
