Description
Technical field
This utility model relates to a kind of electrical contact, is specially a kind of rivet type electrical contact, belongs to electric power applied technical field.
Background technology
Electrical contact, as the core component in high-voltage switch equipment, plays a part to cut-off, turn on, and is widely used in each
Planting high voltage load switch, SF6 chopper, load ratio bridging switch and cut-off greatly in capacity isolating switch and earthed switch, electricity touches
Head is broadly divided into rivet type electrical contact, powder metallurgy contact, blade contact etc., and rivet type electrical contact conducts electricity very well, and surface is not
Oxidizable, arc resistant corrosive power is strong, so being widely applied, it is poor that current electrical contact also exists weldability, works as electricity
When contact welds with other alloys, process is the most difficult, and firm not, and bulk strength is relatively low, the more high defect of production cost.
Therefore, for the problems referred to above, a kind of rivet type electrical contact is proposed.
Summary of the invention
The purpose of this utility model is that provides a kind of rivet type electrical contact to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose, a kind of rivet type electrical contact, including pedestal with
And described pedestal top is provided with salient point, and base bottom arranges back-up ring；Described back-up ring connects head silver cladding, and head silver cladding
Connect base copper；Arrange inside described base copper and afterbody silver cladding is set bottom reinforcement, and base copper.
Preferably, described salient point is cylindrical, and between salient point equidistant Discrete Distribution on the surface of pedestal.
Preferably, described base copper is welded to connect described afterbody silver cladding, and afterbody silver cladding is pyramidal structure.
Preferably, described reinforcement is strip, and the length of reinforcement is identical with base copper length.
Preferably, described back-up ring area is more than the floor space of described pedestal.
The beneficial effects of the utility model are: this kind of contact is provided with the equally distributed small salient point of cloud at top, it is possible to increase
Adding the weldability of contact, when electrical contact welds with the alloy such as bimetal leaf and rustless steel, small salient point makes welding process more
Easy, welding is the most firm；By traditional monomer fine silver or the electric contact of silver alloy, change a social system into head and afterbody use fine silver or
Silver alloy, the middle three layers of compound type contact using pure copper material, there is the electrical contact performance of excellence, and can be not
In the case of affecting serviceability, the effective use saving noble metal, reduces production cost；Reinforcement is had in intrinsic silicon increase
Part so that electrical contact bulk strength is higher；Afterbody uses pyramidal structure so that electrical contact more easily passes location when mounted
Hole, improves installation effectiveness, has good economic benefit and social benefit, be suitable for promoting the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to shown in Fig. 1, a kind of rivet type electrical contact, it is provided with salient point 1 including pedestal 2 and described pedestal 2 top, and
Back-up ring 3 is set bottom pedestal 2；Described back-up ring 3 connects head silver cladding 4, and head silver cladding 4 connects base copper 7；Described cuprio
Layer 7 internal setting arranges afterbody silver cladding 6 bottom reinforcement 5, and base copper 7.
As a kind of technical optimization scheme of the present utility model, described salient point 1 is cylindrical, and between salient point 1 equidistantly
Discrete Distribution is on the surface of pedestal 2 so that contact the most firm with other electric elements.
As a kind of technical optimization scheme of the present utility model, described base copper 7 is welded to connect described afterbody silver cladding 6,
And afterbody silver cladding 6 is pyramidal structure so that junction is the most reliable.
As a kind of technical optimization scheme of the present utility model, described reinforcement 5 is strip, and the length of reinforcement 5
Identical with base copper 7 length, increase the intensity within contact.
As a kind of technical optimization scheme of the present utility model, described back-up ring 3 area is more than the floor space of described pedestal 2,
Effectively prevent contact from loosening.
Afterbody silver cladding 6 in use, is directed at hole, location when fixing by this utility model, and then base copper 7 is through fixed
Hole, position is until back-up ring 3 is fitted with location alloy surface, when electrical contact welds with the alloy such as bimetal leaf and rustless steel, and small salient point
1 make welding process the easiest, welding the most firm, operationally the reinforcement 5 within base copper 7 can strengthen electrical contact
Intensity, increases the service life, and head silver cladding 4 and afterbody silver cladding 6 are made by silver alloy, operationally, thus stable, high
Cut-offfing and turning in the control high-voltage switch equipment of effect.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
