Abstract
The technical scheme of the invention is to provide a conductive contact spring touch finger type connecting device. The connecting device is characterized by comprising a conductor; a contact is externally sleeved on the end part of the conductor; the contact part of the inner wall of the contact and the conductor is provided with a ring groove; a spring touch finger is embedded in the groove; and one end of a guide rod is fixed on the contact, and the other end of the guide rod is inserted in the end part of the conductor. The connecting device provided by the invention has the advantages of simple structure, less components, high current flowing capability and low cost (which is about 65% of that of plum blossom contact insertion-type connection).
Description
Technical field
The present invention relates to a kind of conductive contact spring touch finger formula jockey, be used for the connection between Cubicle Gas-Insulated Switchgear (hereinafter to be referred as the GIS) contact, belong to high voltage electrical apparatus technical field.
Background technology
Mume flower contact plug-in type jockey is all adopted in connection in the Cubicle Gas-Insulated Switchgear (GIS) between the contact at present.As shown in Figure 1, this jockey is generally by contact base 1, spring 2, one group of plum blossom fingertip sheet 3, guide plate 4, guide post 5, radome 6, conductor 7(diameter 90mm) form.Wherein, one group of plum blossom fingertip sheet 3 is made up of 16～32 fingertip sheet, therefore, this connected mode has 32 contact points at most, its through-current capability is subjected to certain restriction (maximum galvanization 4000A), if increase contact point, just must strengthen the diameter of conductor 7, make total become big, be not suitable for GIS to big capacity, small size development.And this connected mode part is various, is made up of 8 kinds of (guide plate 4 has two kinds) different parts, and assembly process is more, and cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of spring touch finger formula jockey, with through-flow limited, the complex structure that solves Mume flower contact plug-in type jockey, the problem that part is many, cost is high.
In order to achieve the above object, technical scheme of the present invention has provided a kind of conductive contact spring touch finger formula jockey, it is characterized in that: comprise conductor, outside the end of conductor, be with contact, have a ring recess at contact inwall and conductor contact position, spring touch finger embeds in this groove, and an end of guide post is fixed on the contact, and the other end inserts in the end of conductor.
The present invention only is made of 4 kinds of parts.Under the identical conductor diameter (diameter 90mm), rated current of the present invention can reach 4800A.
Advantage of the present invention is: simple in structure, part is few, the galvanization ability is strong, cost is low (be Mume flower contact plug-in type connect about 65%).
Description of drawings
Fig. 1 is a Mume flower contact plug-in type jockey schematic diagram in the prior art;
Fig. 2 is a kind of conductive contact spring touch finger formula jockey general structure schematic diagram provided by the invention.
Embodiment
For the present invention is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.
As shown in Figure 2, a kind of conductive contact spring touch finger formula jockey provided by the invention only is made of conductor 8, spring touch finger 10, contact 9, guide post 11 these 4 kinds of parts.Internal diameter, external diameter, decrement by spring touch finger 10 process conductor 8 and contact 9.When assembling connects, spring touch finger 10 is packed in the groove of contact 9 inner surfaces, again guide post 11 is screwed into contact 9, then conductor 8 is inserted 9 li of contacts along guide post 11, compression spring touch finger 10, spring touch finger 10 produces elastic deformation force's (contact pressure), makes between conductor 11, spring touch finger 10 and contact 9 threes closely to be connected.During use, electric current to spring touch finger 10, arrives contact 9 by spring touch finger 10 by conductor 8 again, has finished alive effect.
Structure provided by the invention can be used for the conductor coupling portion position of sulfur hexafluoride gas-insulating metal enclosed switchgear (GIS) median generatrix.Under the identical situation of rated current, owing to removed radome 6 parts such as grade among Fig. 1, the contact diameter has reduced 32%, has made the bus bar canister reduced 18.8%, has not only simplified mechanism and assembly technology, and has reduced cost of manufacture.
Claims (1)
1. conductive contact spring touch finger formula jockey, it is characterized in that: comprise conductor (8), outside the end of conductor (8), be with contact (9), have a ring recess at contact (9) inwall and conductor (8) contact position, spring touch finger (10) embeds in this groove, one end of guide post (11) is fixed on the contact (9), and the other end inserts in the end of conductor (8).
