Problems solved by technology

However, it is difficult for ordinary surge protectors to make the height and bottom area small enough to meet the demand
There are also some surge protectors that reduce the size by sacrificing some functions, but this approach will affect the practical performance of the surge protector

Embodiment Construction

[0037] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0038] The small volume surge protector of the present invention includes a housing, a partition 200 , a lightning protection device 300 , a tripping mechanism 400 and an alarm module 500 .

[0039] see figure 1 with figure 2 , the housing includes a base plate 110 and a rectangular case cover 120 detachably mounted on the base plate 110 . Electrode slots 111 a , 111 b , 111 c are arranged at intervals around the periphery of the base plate 110 , and an alarm pin hole 112 a , 112 b , 112 c is opened on the base plate 110 .

[0040] see image 3 , the partition 200 is disposed in the casing and parallel to the base plate 110 , and the partition 200 divides the inside of the casing into a first installation chamber and a second installation ch...

Abstract

The invention discloses a lightning protection device comprising a piezoresistor and a gas discharge tube, the piezoresistor is provided with a first surface and a second surface opposite to the firstsurface, and a first electrode connected with the piezoresistor is welded on the first surface of the piezoresistor, and a second electrode connected with the piezoresistor is welded on the second surface of the piezoresistor, one side face of the gas discharge tube is welded on the second surface of the piezoresistor and is connected with the second electrode, and a third electrode connected with the gas discharge tube is welded on the other side face of the gas discharge tube. The invention further discloses a surge protection device comprising the lightning protection device. Due to the direct welding of the lightning protection device with the gas discharge tube through the piezoresistor, the welding pins and welding points are reduced, the circuit loop is shorter, and meanwhile, theresidual voltage of the whole lightning protection device circuit can be lower, and the corresponding time is shorter.

Description

technical field [0001] The invention relates to the technical field of small-volume surge protectors, in particular to a lightning protection device and a small-volume surge protector including the lightning protection device. Background technique [0002] Surge protector, also called lightning protector, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When the electrical circuit or communication line suddenly generates a peak current or voltage due to external interference, the surge protector can conduct the shunt in a very short time, thereby avoiding damage to other electronic equipment in the circuit by the surge. [0003] Currently, surge protectors on the market are generally divided into rail-mounted and PCB-mounted types, and the PCB-mounted type has higher requirements for the volume of surge protectors. A surge protector with a small enough size can effectively save the cost of the PC...
