Technical field
The utility model relates to and electrically contacts body structure design and applied technical field, and a kind of elastic contact body of electric power transfer is provided especially.
Background technology
At present, bullet train, the track traffic industry vehicles such as tramcar and subway to adopt the body that electrically contacts have relatively high expectations, require contact to there is good electric continuity, and can stablize and transmit the in the situation that of logical super-high-current.
People urgently wish to obtain the elastic contact body of the good electric power transfer of a kind of technique effect.
Utility model content
Order of the present utility model is to provide one and is mainly used in bullet train, the elastic contact body of the electric power transfer of the track traffic industry vehicles such as tramcar and subway.
Elastic contact body for electric power transfer described in the utility model is constructed as follows: the described elasticity junctor for electric power transfer is constructed as follows: touch base 1, sleeve 2, screw rod 3, Compress Spring 4, zinc-plated annealed copper strand wire 5, soil for electrical contact 6; Described soil for electrical contact 6 is connected in one end of touch base 1, between soil for electrical contact 6 and touch base 1, rivet by special tooling, soil for electrical contact 6 is fine silver rivet contact head, there is anti abrasive characteristic, avoid the corrosion to contact under arcing, and there will not be the incident Welding Phenomena of welding contact; Soldered connecing filled by groove in one end of the other end of touch base 1 and zinc-plated annealed copper strand wire 5, soldered connecing filled by groove in one end of the other end of zinc-plated annealed copper strand wire 5 and screw rod 3, the inner method that adopts zinc-plated annealed copper strand wire 5 of contact increases conductor net sectional area, reduce contact resistance value and overall caloric value, delayed the aging speed of coated metal.Solder flux is selected high temperature scolding tin, can ensure higher conductance, and can melting welding by large current heating in the situation that, the two ends of Compress Spring 4 are connected with screw rod 3 with touch base 1 respectively, Compress Spring 4 is fixed by touch base 1 and the cylinder table of screw rod 3 projections, sleeve 2 is fixed on Compress Spring 4 and zinc-plated annealed copper strand wire 5 outsides, and the two ends of sleeve 2 are connected with screw rod 3 with touch base 1 respectively.Contact adopts elastic contacting structure, and connected mode is fast reliable, reduces the wearing and tearing to contact overlay coating, has extended the useful life of contact.Described contact connects with adopting screw or bolt matable being connected of rear terminal, connects fastening reliable.
Described sleeve adopts the wlding of annular to be connected by Reflow Soldering with screw rod 3.
The surface of described touch base 1 and screw rod 3 is provided with protective layer.
Elastic contact body for electric power transfer described in the utility model, utilize welding annealed copper strand wire increasing section long-pending, silver contact ensures fine row and terminal connections etc., adopt easy reliable connected mode, the quick connection that can realize car end charging with separate, have high temperature resistant, are-tight property, resistance to wear and corrosion resistance, electrical connection stable performance, can realize the electric quick connection of car end and separate, operation is convenient, satisfactory mechanical property, electrical connection is reliable and Electro Magnetic Compatibility is good, long service life and maintenance cost are low, there is comparatively huge economic worth and social value.
