Abstract

The technical scheme of the utility model provides a spring contact finger type connecting device of a conductive contact, characterized by comprising a conductor. A contact is sleeved on the outside of the conductor end part, a ring groove is arranged at the contact position of the contact inner wall and the conductor, and the spring contact finger is embedded in the groove. One end of a guide rod is fixed on the contact, and the other end is inserted in the end part of the conductor. The advantages of the utility model are that the spring contact finger type connecting device of the conductive contact is simple in structure, few in parts, strong in current conduction ability and low in cost( being about 65% of the cost of a plum blossom contact insertion type connection).

Description

A kind of conductive contact spring touch finger formula jockey

Technical field

The utility model relates to a kind of conductive contact spring touch finger formula jockey, is used for the connection between Cubicle Gas-Insulated Switchgear (hereinafter to be referred as the GIS) contact, belongs 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 generally is made up of 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).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 receives 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 the utility model provides 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; The technical scheme of the utility model 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 utility model only is made up of 4 kinds of parts.Under the identical conductor diameter (diameter 90mm), the rated current of the utility model can reach 4800A.

The utility model has the advantages that: 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 sketch map in the prior art;

A kind of conductive contact spring touch finger formula jockey general structure sketch map that Fig. 2 provides for the utility model.

Embodiment

For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.

A kind of conductive contact spring touch finger formula jockey as shown in Figure 2, that the utility model provides only is made up 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 through spring touch finger 10 through conductor 8 again, has accomplished alive effect.

The structure that the utility model provides 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. 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).
