Abstract
The utility model discloses a protection device for a gap switch type self-ignition surge protector, which comprises an inverted-T-shaped base. A circuit board is arranged in a cavity at the upper end of the base. The lower end of the base is parallelly arranged. A plastic protection block is sleeved inside the base. An arc extinguishing chamber and a gas discharge passage are tightly jointed with the plastic protection block. The arc extinguishing chamber is arranged in a cavity formed inside the plastic protection block and is connected with the circuit board by a trigger electrode. An insulated panel is arranged between the arc extinguishing chamber and the circuit board, so that the arc extinguishing chamber and the circuit board are isolated from each other. The plastic protection block is sleeved inside the base. The arc extinguishing chamber and the gas discharge passage are tightly jointed with the plastic protection block. The insulated panel is arranged between the arc extinguishing chamber and the circuit board. In this way, the integral protection performance of the device is improved. Meanwhile, due to the arrangement of the gas discharge passage, gases can be discharged out of the device more conveniently and more quickly. The device also has the advantages of simple structure and convenient usage.
Description
Technical field
The utility model relates to electronic device and makes the field, is specifically related to switch gap type self-ignition surge protector protective device.
Background technology
Existing surge protector is installed in the distribution box; when in electric loop or the communication line because extraneous interference is when producing peak current or voltage suddenly; surge protector can be shunted in the extremely short time in conducting, thereby avoids the infringement of surge to other equipment in the loop.
The protection structure of existing surge protector, arc control device directly are positioned on the base shell of surge protector, and arc control device isolate by plastic spacer mutually with wiring board, are unfavorable for insulating; And a large amount of gases that produce in the arc extinguishing process can not effectively discharge, and original fixed screw is arranged on the gas passing away, have also hindered the gas discharge path, have reduced gas and have discharged efficient.
Processing technology complexity in sum, inefficiency can not effectively be protected equipment.
The utility model content
The technical problems to be solved in the utility model provides switch gap type self-ignition surge protector protective device, plastics protection piece is sheathed in the base, arc control device and the gas passing away plastics protections piece of tightly fitting, insulation board is arranged between arc control device and the wiring board, makes device Global Macros performance improve; And the gas passing away that is provided with makes things convenient for the quick more discharger inside of gas, and is simple in structure, easy to use.
For achieving the above object, the technical solution of the utility model is as follows:
Switch gap type self-ignition surge protector protective device comprises:
The base that is " protruding " type, base upper end cavity is placed wiring board, and the base lower end be arranged in parallel,
Plastics protection piece is sheathed in the base; arc control device and the gas passing away plastics protections piece of tightly fitting; arc control device are positioned at the inner cavity that forms of plastics protection piece; arc control device and wiring board interconnect by trigger electrode; and an insulation board is set between arc control device and the wiring board, isolates arc control device and wiring board.
Preferably, described plastics protection piece comprises two arms that upper end and gas passing away are tightly fitted, and the middle part is the cavity of " protruding " type.
Preferably, described gas passing away is " it " type, one side and at a plurality of nut installing holes of offering of gas passing away.
Preferably, base lower end one side is provided with a pore, makes things convenient for the thorough discharger of the gas that produces in arc extinguishing process inside.
By technique scheme, the beneficial effects of the utility model are:
Plastics protection piece is sheathed in the base, arc control device and the gas passing away plastics protections piece of tightly fitting, insulation board is arranged between arc control device and the wiring board, and arc control device and wiring board are also gapped, having guaranteed between the components and parts not can the phase mutual interference, makes device Global Macros performance improve; And the gas passing away that is provided with makes things convenient for the quick more discharger inside of gas, and is simple in structure, easy to use.
