Abstract
A taper fastening and connection device comprises a taper, an outer conductor is mounted in the taper through a bolt, and a tinned copper foil is arranged on a taper conductive surface between the taper and the outer conductor. In the taper fastening and connection device provided by the utility model, the tinned copper foil with a proper thickness serves as a gap filler, during assembly, the tinned copper foil is processed into the size of the outer wall of the taper conductive surface, and certain anti-oxidation lipid is applied for the insertion of the outer conductor. Therefore, the oxidation in the gap between the two conductor contact surfaces is effectively overcome and the overheat probability on the contact surface between the conductors is reduced.
Description
Technical field
The utility model relates to a kind of electrical connection arrangement, and particularly a kind of awl that pulls out is fastenedly connected device.
Background technology
Exist during isolation switch in the power equipment, conductor privileged sites connect to adopt to pull out to bore to be fastenedly connected the parts of mode, and find in the equipment operation that superheating phenomenon can appear in this position.This is because outer conductor is that plug-in type is assembled with pulling out awl, there is certain tolerance fit, when pulling out the awl conducting surface when contacting with outer conductor, there is certain space between two contact-making surfaces, effectively contact area does not reach designing requirement, and oxidation takes place in the contact-making surface that has the space under atmospheric environment and electromagnetic action, causes that superheating phenomenon appears in contact-making surface between two conductors.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of awl that pulls out and is fastenedly connected device, can avoid pulling out between awl conducting surface and the outer conductor superheating phenomenon occurring.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of awl that pulls out is fastenedly connected device, comprises and pulls out awl, and outer conductor is installed in by bolt and pulls out in the awl, is provided with zinc-plated Copper Foil at the awl conducting surface that pulls out that pulls out between awl and the outer conductor.
A kind of awl that pulls out that the utility model provides is fastenedly connected device, zinc-plated Copper Foil by selecting suitable thickness is as void filler, in assembling process, zinc-plated Copper Foil is processed into the size of pulling out awl conducting surface outer wall, and smear an amount of anti-oxidation fat, insert assembling with outer conductor, can solve effectively between two conductor contact-making surfaces because of existing the space that the phenomenon of oxidation takes place, reduce that overheated probability appears in contact-making surface between conductor.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Embodiment
In Fig. 1, a kind of awl that pulls out is fastenedly connected device, comprises and pulls out awl 4, and outer conductor 1 is installed in by bolt 5 and pulls out in the awl 4, is provided with zinc-plated Copper Foil 3 at the awl conducting surface 2 that pulls out that pulls out between awl 4 and the outer conductor 1.This zinc-plated Copper Foil 3 is two-sided zinc-plated Copper Foil.Zinc-plated Copper Foil 3 is processed into the size and dimension that pulls out awl conducting surface 2 outer walls when assembling, when bolt 5 is tightened, zinc-plated Copper Foil 3 fully distortion is filled in the space of pulling out between awl conducting surface 2 and outer conductor 1 inwall, thereby has guaranteed that contact is good, reduces overheated probability to occur.
Claims (1)
1. one kind is pulled out awl and is fastenedly connected device, comprises and pull out awl (4) that outer conductor (1) is installed in by bolt (5) and pulls out in the awl (4), it is characterized in that: bore conducting surface (2) and be provided with zinc-plated Copper Foil (3) pulling out pulling out between awl (4) and the outer conductor (1).
