Description
Technical field
The utility model relates to a kind of auxiliary contact of surge protector and surge protectors.
Background technique
Surge protector is a kind of common low-voltage variation device, and under normal circumstances, it is in high impedance status, and one
Denier route because lightning stroke or other reasons there is surge when, it can be connected in a very short period of time, and lightning current or overvoltage are passed through
Ground line introduces the earth, and the equipment on protection circuit is carried out with this.When surge protector because a variety of causes causes to deteriorate, surge at this time
Acute fever can be swashed in protector, so that the trip gear in surge protector be made to act, be detached from surge protector and route, prevented
Only surge protector " short circuit ", causes line accident to magnify, and after surge protector and route disengaging, route will not be protected
Shield, by may determine that whether surge protector has been detached from route to auxiliary contact detection.Thus auxiliary contact structure and
Electric property quality can directly have an impact the use of surge protector.
The auxiliary contact of existing surge protector generally uses microswitch or metal clips to add bump form.Mainly deposit
The drawbacks of be that the volume of microswitch is big, while at high cost.Metal clips bump form structure shakiness be easy because vibration etc. its
Its factor and cause to malfunction, while to be also easy to appear bump stuck for this structure, and surge protector has been threaded off its bump structure
There is no state transformation, and generates the warning message of mistake.
Utility model content
The utility model existing surge protector auxiliary contact there are aiming at the problem that, a kind of the auxiliary of surge protector is provided
Contact is helped, structural stability is good, and use reliability is high, and antivibration effect is good, and at low cost, being used for can accurate response in surge protector
The tripping of surge protector changes with the state that do not thread off.The utility model also provides a kind of surge protector.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
The auxiliary contact of surge protector, including the stationary contact tip electrode being separately mounted in surge protector and moving contact electricity
Pole, it is characterised in that the stationary contact tip electrode and moving contact electrode all has contact flat spring, and the contact bullet of moving contact electrode
Piece is pressed on the contact flat spring of stationary contact tip electrode, connects moving contact electrode and stationary contact tip electrode.
Preferably, this stationary contact tip electrode includes the pin one and contact flat spring one stretched out from surge protector,
The moving contact electrode includes the pin two and contact flat spring two stretched out in surge protector, and the contact flat spring two compresses
On contact flat spring one.
Preferably, the contact flat spring one is the arc spring lamination to arch upward upwards, and the contact flat spring two is bar shaped bullet
Piece, and the front end of contact flat spring two is in writing board shape, is pressed on contact flat spring one.
Preferably, the width of the contact flat spring two is greater than the width of contact flat spring one.
Preferably, the stationary contact tip electrode and moving contact electrode respectively with the inner box snap-fit of surge protector.
Surge protector, it is characterised in that auxiliary contact, voltage protection component including above-described surge protector
Component and the tripping arc extinguishing component clamped by voltage protection component component, the tripping arc extinguishing component are pressed on moving contact electrode
Contact flat spring on.
The beneficial effects of the utility model are:
1, stationary contact tip electrode and moving contact electrode are connected by contact flat spring, can accurate response surge protector tripping with
The state transformation that do not thread off.
2, stationary contact tip electrode and moving contact electrode are compressed by contact flat spring connects, and structural stability is good, contact area
Greatly, contact resistance is small.
3, stationary contact tip electrode and moving contact electrode all have contact flat spring, and the high reliablity of contact increases surge protector
The error displacement of middle tripping arc extinguishing component, reduces the malfuncton probability of auxiliary contact, and use reliability is high.
4, the moving contact of auxiliary contact and static contact all have contact flat spring, and anti-vibration effect is more preferable, will not because vibration or
Other reasons and occur mistake alarm.
5, stationary contact tip electrode contacts connection by contact flat spring with moving contact electrode, at low cost, can reduce surge protection
The cost of manufacture of device.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the utility model in surge protector.
Fig. 2 is the structural schematic diagram of stationary contact tip electrode.
Fig. 3 is the structural schematic diagram of moving contact electrode.
Fig. 4 is that the structural schematic diagram after arc extinguishing tripping occurs for surge protector.
Specific embodiment
The utility model will be further described by attached drawing 1 ~ 4 and embodiment below.
The auxiliary contact of surge protector, including the stationary contact tip electrode 1 being separately mounted in surge protector and moving contact
Electrode 2, it is characterised in that the stationary contact tip electrode 1 and moving contact electrode 2 all has contact flat spring, and moving contact electrode 2
Contact flat spring is pressed on the contact flat spring of stationary contact tip electrode 1, connects moving contact electrode 2 and stationary contact tip electrode 1.
This stationary contact tip electrode 1 includes the pin 1 and contact flat spring 1 stretched out from surge protector, institute
The moving contact electrode 2 stated includes the pin 2 21 and contact flat spring 2 22 stretched out in surge protector, the contact flat spring two
22 are pressed on contact flat spring 1.
The contact flat spring 1 is the arc spring lamination to arch upward upwards, and the contact flat spring 2 22 is bar shaped elastic slice,
And the front end of contact flat spring 2 22 is in writing board shape, is pressed on contact flat spring 1.
As shown in Figure 1, contact flat spring 2 22 is pressed on contact flat spring 1 in surge protector, moving contact electrode 2
In an ON state with stationary contact tip electrode 1, surge protector is in non-trip status, goes out as shown in figure 4, surge protector is in
Arc trip status, contact flat spring 2 22 are flicked from contact flat spring 1, and stationary contact tip electrode 1 and moving contact electrode 2 disconnect.Stationary contact
Tip electrode 1 and moving contact electrode 2 are connected by contact flat spring, can accurate response surge protector tripping and the state do not threaded off
