Abstract
The invention discloses a contact arm sealing ring, which comprises a contact arm sealing ring body, a chamfered part and a groove, wherein the contact arm sealing ring body is approximately circular-ring-shaped; the chamfered part is arranged on the inner side of a hole contact with the end part of the contact arm sealing ring body, which is contact with a contact arm; the groove is formed on the inner side of the end part of the contact arm sealing ring body, which is contact with a terminal post joint housing and used for clamping the terminal post joint housing; and the contact arm sealing ring body is manufactured by adopting silicone rubber. The contact arm sealing ring disclosed by the invention is provided with the chamfered part and the groove, so that an outlet terminal can be closely contact and sealed with the contact arm; and the contact arm sealing ring is manufactured by adopting the silicone rubber, so that a contact part can be totally sealed and the insulating ability and the antifouling ability are greatly improved.
Description
Technical field
The present invention relates to a kind of improvement of contact arm sealing ring, particularly a kind of outlet terminal that can make contacts the contact arm sealing ring that the conducting surface contact site seals fully with contact arm, belong to electric equipment parts technical field.
Background technology
In the past, indoor high-voltage vacuum circuit breaker was used insulating cylinder, and the outlet arm is equipped with at top and middle part respectively; Last outlet arm is through upper bracket and the quiet end fixed connection of arc control device, following outlet arm through lower carriage, be flexible coupling and vacuum interrupter moved end conducting rod connects, be tetragonal inside and outside the insulating cylinder top; The bottom is inside and outside to be circle configurations; Be equipped with the shirt rim structure inside and outside the insulating cylinder, its inner skirt is whole circle circle configurations, and upper and lower support is directly fixed on insulating cylinder inside.
Existing pole lower wire end seals through common annular seal ring with contact arm conducting surface contact site, is not to seal fully usually, has certain air gap, causes this position to be easy to generate partial discharge.
Summary of the invention
The object of the present invention is to provide a kind of outlet terminal that can make to contact the contact arm sealing ring that the conducting surface contact site seals fully with contact arm.
The present invention realizes through following technical scheme: a kind of contact arm sealing ring comprises contact arm sealing ring body, chamfered section, groove; Said contact arm sealing ring body roughly is annular; Said chamfered section is arranged on the inboard in the hole of the end contact that contacts with contact arm on the contact arm sealing ring body; On the inboard, end that said groove is arranged on the contact arm sealing ring body with the pole joint housing contacts, be used for blocking the pole joint housing.
Preferably, said contact arm sealing ring body adopts silicon rubber to process.
Beneficial effect of the present invention is embodied in: contact arm sealing ring of the present invention, be provided with chamfered section and groove on the said contact arm sealing ring body, and can make outlet terminal closely contact and seal with contact arm; The present invention adopts silicon rubber to process, and the contact site potential energy is sealed fully, improves insulating capacity and antifouling ability greatly.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the cutaway view of contact arm sealing ring of the present invention;
Cutaway view when accompanying drawing 2 is the application state of contact arm sealing ring of the present invention;
Wherein: 1, contact arm sealing ring; 2, contact arm; 3, contact arm housing; 4, go up outlet terminal; 5, through hole; 6, screw; 7, pole joint housing; 11, contact arm sealing ring body; 12, chamfered section; 13, groove.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of contact arm sealing ring 1 of the present invention like accompanying drawing 1,2, comprise contact arm sealing ring body 11, chamfered section 12, groove 13; Said contact arm sealing ring body 11 roughly is annular; Said chamfered section 12 is arranged on the inboard in the hole of the end contact that contacts with contact arm 2 on the contact arm sealing ring body 11; On the inboard, end that said groove 13 is arranged on the contact arm sealing ring body 11 with pole joint housing 7 contacts, be used for blocking pole joint housing 7; Said contact arm sealing ring body 11 adopts silicon rubber to process.Shown in accompanying drawing 2, pole joint housing 7 is inserted in contact arm sealing ring body 11 upper grooves 13; The shape of said groove 13 is consistent with the end shape of pole joint housing 7; Said outlet terminal 4 is arranged in the pole joint housing 7; Contact arm 2 is by contact arm shell 3 parcels; Said contact arm 2 inserts on the contact arm sealing rings 1 in the chamfered section 12; Said chamfered section 12 is consistent with the end shape of contact arm 2; The contact-making surface of contact arm 2 is closely contacted with outlet terminal 4, and the through hole 5 that passes on the contact arm 2 of screw 6 is closely fixing with outlet terminal 4 and contact arm 2 then.
Beneficial effect of the present invention is embodied in: contact arm sealing ring of the present invention, be provided with chamfered section and groove on the said contact arm sealing ring body, and can make outlet terminal closely contact and seal with contact arm; The present invention adopts silicon rubber to process, and the contact site potential energy is sealed fully, improves insulating capacity and antifouling ability greatly.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
