Abstract
The invention relates to a fusing device of a power source surge protector. The fusing device comprises a base body (14). The fusing device is characterized in that an incoming line wire holder (12) and a connecting piece (7) of a user equipment power source (3) are respectively connected to the base body (14), a conducting rod (11) is connected to the incoming line wire holder (12), a connecting rod (10) is hinged to the conducting rod (11), a conducting piece (9) is connected to the connecting rod (10), the conducting piece (9) is connected with the connecting piece (7) through a fuse (8), and the lower portion of the conducting piece (9) is connected with the base body (14) through a spring (13). The fusing device has the advantages of being simple in structure, safe and reliable, high in short-circuit and overheating protection response speed, small in equipment residual voltage, and capable of effectively protecting the power source against damage of surge voltage.
Description
Technical field
The present invention relates to a kind of power source surge protector, particularly a kind of device for fusing of power source surge protector.
Background technology
Thunder and lightning is a kind of special weather phenomenon of aloft being discharged and being caused by charged cloud, thunder and lightning is the major reason that causes electronic equipment to damage, thunderbolt can cause great surge voltage of moment, surge voltage is the arch-criminal of harm security appliance, for power supply, once surge voltage causes it to damage, can cause whole electrical system to provide cannot work, or even damage, thereby need a kind of device that causes power supply to damage due to surge voltage.
Summary of the invention
The object of the invention is the shortcoming existing in prior art in order to solve, and the device for fusing of a kind of power source surge protector proposing.
To achieve these goals, the present invention has adopted following technical scheme:
A kind of device for fusing of power source surge protector; comprise pedestal; it is characterized in that: the brace that is connected with respectively inlet wire side junction block and subscriber equipment power supply on pedestal; on described inlet wire side junction block, connect a conducting rod; a hinged connecting rod on conducting rod; on connecting rod, connect a conducting strip, described conducting strip is connected with described brace by fuse, below conducting strip, also by spring, connects pedestal.
On the basis of technique scheme, can there is following further technical scheme:
Described spring is always in compressive state.
The invention has the advantages that: this apparatus structure is simple, safe and reliable, short circuit, overtemperature protection fast response time, equipment residual voltage is little, and effectively protection power source is avoided the harm of surge voltage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1; the device for fusing of a kind of power source surge protector provided by the invention; comprise pedestal 14; it is characterized in that: the brace 7 that is connected with respectively inlet wire side junction block 12 and subscriber equipment power supply 3 on pedestal 14; on described inlet wire side junction block 12, connect a conducting rod 11; a hinged connecting rod 10 on conducting rod 11; on connecting rod 10, connect a conducting strip 9; described conducting strip 9 is connected with described brace 7 by fuse 8, below conducting strip 9, also by spring 13, connects pedestal 14.
Described spring 13 is always in slight compressive state, and when conducting strip 9 is connected with brace 7, the elastic force of spring 13, can not make fuse 8 distortion, with the performance of guarantee insurance silk 8.
During excessive the or excess Temperature of electric current in supply line's power supply 1, fuse 8 disconnects, and conducting strip 9 is separated with brace 7, has formed certain isolation breakpoint, the described stage clip 13 of colleague is pushed conducting strip 9 open, prevents secondary contact conduction damage subscriber equipment power supply 3.
Claims (2)
1. the device for fusing of a power source surge protector, comprise pedestal (14), it is characterized in that: the brace (7) that is connected with respectively inlet wire side junction block (12) and subscriber equipment power supply (3) on pedestal (14), the upper conducting rod (11) that connects of described inlet wire side junction block (12), at the upper hinged connecting rod (10) of conducting rod (11), at the upper conducting strip (9) that connects of connecting rod (10), described conducting strip (9) is connected with described brace (7) by fuse (8), below at conducting strip (9) also connects pedestal (14) by spring (13).
2. the device for fusing of a kind of power source surge protector according to claim 1, is characterized in that: described spring (13) is always in compressive state.
