Problems solved by technology

In the assembly structure of conventional surge protector (SPD) devices, MOV chips need to go through four or five processes such as two-sided welding to lead out electrodes, cleaning, encapsulation, boxing, and potting, which consumes time and energy and is not environmentally friendly. ;Assembled parts have no positioning and orientation, are easy to be installed incorrectly, and require high assembly requirements; heat dissipation performance needs to be improved, resulting in reduced reliability

Embodiment 1

[0032] like Figure 1a , 1b As shown, the embodiment of the present invention provides a surge protector adopting a box-type fastening assembly structure, including an insulating box body 1, and the bottom of the insulating box body is located at about two-thirds of the total height of the insulating box body 1, so that The insulating box body is divided into two parts, the deep side of the box is installed with the MOV chip 3, and the shallow side of the box is installed with the tripping device. The four corners of the insulating box are provided with four hollow fixing studs 1-2, and the tripping electrode 2-1 of the tripping electrode sheet 2 extends out of the through hole 1-4 at the bottom of the insulating box 1, and the plane of the tripping electrode is insulated from the insulating box. The protruding points 1-3 at the bottom of the box are bonded, and the other side is bonded to one side of the MOV chip 3. One side of the upper electrode splint 5 is pressed on the o...

Embodiment 2

[0043] The difference between this embodiment and embodiment 1 is:

[0044] like Figure 2a , 2b , 2c, the tripping electrode piece 2, MOV chip 3, and upper electrode splint 5 are fixed in the insulating box body 1 to form a box-type fastening assembly structure, and the top of the box-type fastening assembly structure is filled with Sealed with insulating adhesive layer 70, see Figure 2b . The bottom of the insulating box is further provided with four protruding points 1-3 which are evenly distributed and have the same height, and their heights are set to ensure the flow of the potting glue.

[0045] The insulating adhesive layer 70 is made of epoxy resin, phenolic resin, silicone material and the like.

[0046] The assembly process of the surge protector using the box-type fastening assembly structure of the above-mentioned embodiment of the present invention is as follows:

[0047] Place the side of the tripping electrode 2 with the pin 2-1 facing the bottom of the in...

Embodiment 3

[0049] like Figure 4a , 4b As shown, the difference between this embodiment and the previous two examples is that the insulating box body 1 is not divided into two parts, and a deep insulating box body is used, which is assembled on the same side. The assembly process of the device is as follows: Align the notch on the two sides of the lead-out pin 2-2 of the tripping electrode piece 2 with the slot 1-6 on the insulating box body 1, and make the bottom surface of the tripping electrode piece 2 close to the insulating box The protruding point 1-3 at the bottom of the body 1 is inserted into the MOV chip, and the upper electrode splint 5 is covered, and the screw or rivet 6 is passed through the four corner through holes 5-1 of the upper electrode splint 5, and fastened to the four corners of the bottom of the insulating box body 1. In the hole of the stud 1-2, align the notch on both sides of the lead-out electrode 7 with the slot 1-7 on the insulating box body 1 and snap it ...

Abstract

The invention provides a surge protective device applying a box-type fastening assembly structure. The surge protective device comprises an insulation box body, at least one tripping electrode plate, at least one metal oxide varistor (MOV) chip and an upper electrode clamping plate, wherein the tripping electrode plate and the MOV chip are alternatively arranged, the at least one tripping electrode plate, the at least one MOV chip and the upper electrode clamping electrode are fixed in the insulation box body by a fastening element, the bottom of the insulation box body is in crimping connection with the tripping electrode plate, an insulation rubber sleeve is sleeved outside the MOV chip, or an insulation rubber layer is encapsulated in the box-type fastening assembly structure. The surge protective device applying the box-type fastening assembly structure, disclosed by the invention, has the advantages of no need of welding and cleaning, labor and time saving, environmental friendliness, high cooling performance, reliable tripping and high assembly efficiency.

Description

technical field [0001] The invention relates to the technical field of surge protector assembly, in particular to a surge protector adopting a box-type fastening assembly structure. Background technique [0002] A conventional voltage-limiting surge protector (Surge Protective Device, SPD for short) has a special nonlinear current-voltage characteristic. It is mainly composed of passive electronic components MOV (Metal Oxide Varistors, zinc oxide varistor) chip assembly. Once abnormal conditions occur, such as lightning strikes, electromagnetic field interference, frequent power switch actions, power system failures, etc., the voltage on the line increases suddenly, exceeding the conduction voltage of the surge protector (SPD), and it will enter the conduction zone. The current (I) and voltage (V) have a nonlinear relationship, which is generally called the nonlinearity parameter (Nonlinearity Parameter), and its value can reach tens or hundreds. At this time, the impedanc...
