Description
Technical field
The utility model relates to the earthing that a kind of high-voltage switch gear arranges cashier's office in a shop, particularly refer on earthing contact apparatus.
Background technology
The contact apparatus of the earthing that existing high-voltage switch gear cashier's office in a shop arranges includes fixed contact and moving contact, wherein fixed contact is fixedly installed, the hinged setting of moving contact, the top of fixed contact becomes to diverge to setting, the contact jaw slabbing of moving contact, and the sheet of moving contact can be inserted diverging to of fixed contact and in portion, realize both electrical connections like this, the shortcoming of this connected mode is, contact point is few, and conductivity is bad, electronic and thermal stability is low.
Summary of the invention
The utility model overcomes the deficiency that prior art exists, and provides a kind of contact-making surface large, good conductivity, the contact apparatus to the less demanding novel earthing of machining accuracy.
In order to realize above object, the utility model is by the following technical solutions: a kind of contact apparatus of earthing, include fixed contact and moving contact, it is characterized in that: described fixed contact includes installation portion and connecting portion, described connecting portion becomes cylindrical, described moving contact includes articulated section, swing arm and socket part, wherein articulated section is by the hinged support that is arranged on earthing of bearing pin, swing arm is arranged between articulated section and socket part, described socket part is provided with manhole, this through hole can coordinate with the connecting portion socket of fixed contact, on the manhole inwall of described socket part, around one circle, be at least provided with the accommodating ring recess of twice, in described accommodating ring recess, be respectively arranged with the spring touch finger being formed by spring bending, the connecting portion socket of through hole and fixed contact coordinates being electrically connected between rear spring fingertip formation fixed contact and moving contact.
By adopting such scheme, the effect reaching is: 1, structure is simpler, and volume is little, and materials are economized, and cost is low; 2, many, the good conductivity of contact point, electronic and thermal stability is high; 3, the contact of each contact point is not high, has good resistance to wear in breaking-closing operating; 4, compress variation is large, less demanding to machining accuracy, and mismachining tolerance and rigging error are had to larger adaptability, is more suitable for large-scale production.
The scheme of further setting of the present utility model, the periphery that establish on the top of described connecting portion is arranged to cambered surface, the both sides end face of described through hole is also arranged to oblique cambered surface, the articulated section of described moving contact, swing arm and socket part be split setting respectively, between articulated section, swing arm and socket part, is bolted; In described through hole, be provided with the accommodating ring recess of twice, the accommodating ring recess of twice arranges at interval, and after described spring touch finger is arranged in accommodating ring recess, the diameter of its inner ring is less than the diameter of connecting portion.
By adopting such scheme, product is used convenient, guarantee the stability of product conduction when work, the periphery that wherein establish on the top of connecting portion is arranged to cambered surface, the both sides end face of described through hole is also arranged to oblique cambered surface, moving contact can well dock the connecting portion of fixed contact when swinging like this, can not be interfered.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is the A portion enlarged drawing in Fig. 1;
Fig. 3 is the spring touch finger structural representation of the utility model embodiment.
Embodiment
As shown in Fig. 1-Fig. 3, a kind of contact apparatus of earthing, include fixed contact 1 and moving contact 2, described fixed contact 1 includes installation portion 11 and connecting portion 12, 12 one-tenth of described connecting portions are cylindrical, described moving contact 2 includes articulated section 21, swing arm 22 and socket part 23, wherein articulated section 21 is by the hinged support that is arranged on earthing of bearing pin, swing arm 22 is arranged between 21He socket part, articulated section 23, described socket part 23 is provided with manhole 231, this through hole 231 can coordinate with connecting portion 12 sockets of fixed contact 1, on manhole 231 inwalls of described socket part 23, around one circle, be at least provided with the accommodating ring recess 232 of twice, in described accommodating ring recess 232, be respectively arranged with the spring touch finger 2321 being formed by spring bending, connecting portion 12 sockets of manhole 231 and fixed contact 1 coordinate being electrically connected between rear spring fingertip 2321 formation fixed contacts 1 and moving contact 2.By adopting such scheme, the effect reaching is: one, structure is simpler, and volume is little, and materials are economized, and cost is low; Two, many, the good conductivity of contact point, electronic and thermal stability is high; Three, the contact of each contact point is not high, has good resistance to wear in breaking-closing operating; Four, compress variation is large, less demanding to machining accuracy, and mismachining tolerance and rigging error are had to larger adaptability, is more suitable for large-scale production.
In the utility model embodiment, the periphery 121 that establish on the top of described connecting portion 12 is arranged to cambered surface, the both sides end face of described through hole 231 is also arranged to oblique cambered surface 2311, and moving contact 2 can well dock the connecting portion 12 of fixed contact 1 when swinging like this, can not be interfered.The articulated section 21 of described moving contact 2, swing arm 22 and the other split setting of socket part 23, be bolted between articulated section 21, swing arm 22 and socket part 23, can produce installation in batches like this; In described through hole 231, be provided with the accommodating ring recess 232 of twice, the accommodating ring recess 232 of twice arranges at interval, and described spring touch finger 2321 is arranged on the diameter that the interior diameter of its inner ring 23211 afterwards of accommodating ring recess 232 is less than connecting portion 12.
