Description

A Quick Disconnect Surge Protector

technical field

The utility model relates to the technical field of separation and cutting of a surge protector, in particular to a rapidly separating surge protector.

Background technique

Surges and peak voltages (impulses) refer to increases in "regular" voltage, usually caused by dramatic fluctuations or increases in power demand. Turning on large surge power appliances, vacuum cleaners, air conditioners, washing machines can all cause surges and voltage spikes. Any type of interference can damage electronic equipment. Beyond the scope of actual repair. In addition, severe weather (lightning) and the power company's routine shutdowns and repairs can introduce damaging surges to power lines. Surge protectors act like automatic electrical floodgates, capable of dumping dangerous extra voltages and bursts of high current into the ground, preventing most of these dangerous voltages from damaging your sensitive equipment. Therefore, how to quickly cut off the large current, avoid electrical damage, reduce or avoid potential safety hazards has become a research hotspot in the industry. Therefore, it is necessary to provide a quick disconnect surge protector.

Utility model content

The purpose of the utility model is to provide a quick-separation surge protector aiming at the defects and deficiencies of the prior art.

For realizing above-mentioned object, the technical scheme that the utility model adopts is:

A quick-separation surge protector described in the utility model includes a housing, the inner cavity of the housing is provided with an upper conductive pin and a lower conductive pin, and one end of the upper conductive pin is connected to the upper end side of the housing. After the wall is fixedly connected, it protrudes out of the shell, and one end of the lower conductive pin is fixedly connected with the lower end side wall of the shell and then protrudes out of the shell; One end is hinged with one end of the middle connecting foot, the other end of the middle connecting foot is fixedly provided with an earring, the left side wall of the inner cavity of the housing is fixedly provided with an earring seat, and an earring seat is fixedly provided with an earring, and the two earrings are connected by a spring Get up; the middle connecting pin is also fixedly connected with an upper connecting piece, and the other end of the lower conductive pin is fixedly provided with a lower connecting piece, and the upper connecting piece and the lower connecting piece are connected by welding.

Further, the longitudinal section of the middle connecting leg is arc-shaped, and the arc is two-thirds of a circle.

Further, the other end of the upper conductive pin is also fixedly connected with a damping block matching the middle connecting pin.

Further, the upper connecting piece and the lower connecting piece are both provided with welding through holes.

Further, the earrings and the earring seat are both made of insulating materials.

After adopting the above structure, the beneficial effect of the utility model is: when using the utility model, when a large current passes through the device, the welding part between the upper connector and the lower connector will melt off, and the spring will recover its elasticity at this time Deformation drives the middle connecting foot and the upper connecting piece to move to the left, so as to realize rapid separation; quickly cut off the large current, avoid electrical damage, reduce or avoid potential safety hazards.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 to 2, a quick-disconnect surge protector according to the utility model includes a housing 1, and the inner cavity of the housing 1 is provided with an upper conductive pin 2 and a lower conductive pin 3. One end of the upper conductive pin 2 is fixedly connected to the upper side wall of the housing 1 and then protrudes out of the housing 1, and one end of the lower conductive pin 3 is fixedly connected to the lower side wall of the housing 1 and then protrudes out of the housing 1 outside.

The inner cavity of the housing 1 is also provided with an intermediate connecting pin 4, the other end of the upper conductive pin 2 is hinged to one end of the intermediate connecting pin 4, and the other end of the intermediate connecting pin 4 is fixedly provided with an earring 6. An earring seat 8 is fixedly arranged on the left side wall of the inner cavity, and an earring 6 is fixedly arranged on the earring seat 8 , and the two earrings 6 are connected by a spring 7 .

The middle connecting pin 4 is also fixedly connected with an upper connecting piece 5, and the other end of the lower conductive pin 3 is fixedly provided with a lower connecting piece 3-1, when the upper connecting piece 5 and the lower connecting piece 3-1 are connected by welding Time; Spring 7 is stretched state.

Further, as shown in Figure 3, the longitudinal section of the intermediate connecting pin 4 is arc-shaped, and the arc is two-thirds of a circle; when the intermediate connecting pin 4 is not equipped with a spring 7, the intermediate connecting pin 4 is in the When freely hanging on the upper conductive pin 2, the upper connector 5 is located on the left side of the lower connector 3-1, that is, the upper connector 5 and the lower connector 3-1 are not on the same longitudinal section, so it can be seen that the device Separation can also be achieved without the action of a spring.

Further, the other end of the upper conductive pin 2 is also fixedly connected with a damping block 9 matching the middle connecting pin 4 for blocking the tendency of the middle connecting pin 4 to move to the left.

Further, both the upper connecting piece 5 and the lower connecting piece 3-1 are provided with welding through holes, that is, during welding, the two welding through holes are aligned, and tin is filled into the welding through holes, which is convenient for welding and can Improve connection stability.

Further, the earrings 6 and the earring seat 8 are both made of insulating materials.

When using the utility model, when a large current passes through the device, the welding part between the upper connecting piece and the lower connecting piece will melt off, and the spring will recover elastic deformation at this time, driving the middle connecting foot and the upper connecting piece to the left Side movement, so as to achieve rapid separation; quickly cut off large currents, avoid electrical damage, reduce or avoid safety hazards.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
