Description
Technical field
The present invention relates to a kind of high-tension connector.
Background technology
At present, high-voltage conducting wires connects by round thread high-tension connector or circular bayonet socket high-tension connector, above-mentioned two kinds of high-tension connectors comprise the socket and the plug that cooperatively interact, between socket and plug, be threaded connection respectively or bayonet socket connects, but the volume of round thread or circular bayonet socket high-tension connector is large, Heavy Weight, installation inconvenience.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of volume high-tension connector little, easy for installation.
For solving the problems of the technologies described above, the invention provides a kind of high-tension connector, comprise socket and plug;
Described socket comprises hollow Socket casing, the contact pin of soft board, metal is installed, Socket casing is enclosed within installs soft board outside, soft board rear portion is installed and has several insertion tube grooves, soft board front portion is installed and has several wire casings, wire casing is corresponding one by one with insertion tube groove, between wire casing and insertion tube groove, is provided with contact pin, and contact pin front end stretches in insertion tube groove, Socket casing middle part is outward extended with the first flange, and the first flange upper surface has connecting through hole;
Described plug comprises plug casing, seal cover board, rubber injection sleeve, insertion tube and metal sleeve, plug casing front end face has the grafting groove that coordinates Socket casing, on grafting groove rear wall, there is the insertion tube of several and insertion tube groove fit, described insertion tube front end has the internal projecting ring extending internally, insertion tube middle part is placed with metal sleeve, in metal sleeve, there is jack, plug casing rear side is fixedly connected with rubber injection sleeve, rubber injection sleeve rear side has seal cover board, plug rear portion has several lead channels, each lead channels runs through respectively seal cover board successively, plug casing stretches into insertion tube, there is the second flange the first flange position of plug casing respective socket, between the second flange and the first flange, be bolted.
Adopt after such structure, some high-voltage conducting wires stretch in the wire casing of socket, and connect one to one with contact pin; Some high-voltage conducting wires stretch in the lead channels of plug, and connect one to one with the metal sleeve in insertion tube, use afterwards casting glue to carry out embedding in rubber injection sleeve, to guarantee good withstand voltage properties;
Socket and plug coordinates, first socket is stretched in plug, the insertion tube correspondence of plug enters in the insertion tube groove that soft board is installed, contact pin in insertion tube groove enters in the metal sleeve in insertion tube, metal sleeve in the time plugging together and contact pin form Elastic Contact, produce low contact resistance, thereby realize good electrical connection, complete between plug and socket and be communicated with, because when plug inserts the insertion tube groove that soft board is installed, insertion tube groove can coordinate insertion tube to produce deformation, makes to plug together interfacial seal, thereby effectively block air gap path, reached high voltage withstanding object;
After grafting, interconnect by the first flange of plug and the second flange of socket, position between plug and socket is interfixed; Because installing space is limited, by the connecting through hole of the first flange upper surface, conveniently this high-tension connector after plugging together is horizontally fixed on external equipment, reach the object that reduces setting height(from bottom).
Useful technique effect of the present invention is: volume is little, easy for installation, reduction setting height(from bottom).
In the insertion tube recess sidewall of this high-tension connector, there are some sealing bulge loops that extend internally; Adopt after such structure, while plugging together between insertion tube groove and insertion tube, sealing bulge loop can form certain elastic compression, promotes the sealing that plugs together interface, has reached high voltage withstanding object.
The plug casing of this high-tension connector and the material of Socket casing are all insulating material, and the material that soft board is installed is low temperature resistant silicon rubber.
Adopt after such structure, the material of plug casing and Socket casing adopts insulating material, the fail safe that improves this high-tension connector; Soft board is installed and is used low temperature material, can under cryogenic conditions, still can keep for a long time good elasticity, and low temperature resistant silicon rubber is under low-temperature and low-pressure condition, still has good sealing, its withstand voltage properties meets the demands.
The metal sleeve of this high-tension connector is two lobe groove structures and plated surface gold firmly; Adopt after such structure, after closing in, there is good elasticity, be convenient to contact between metal sleeve and contact pin.
