Abstract
The utility model discloses an insertion end matching structure of a high-voltage connector, which comprises a plug and a socket, wherein the shells of the plug and the socket are made of insulated materials; the plug is inserted into the socket in an interference mode; and the joint of the plug and the socket is provided with a metal contact element. The utility model is characterized in that the periphery of one end of the plug, which is inserted into the socket, is provided with an arc-shaped convex ring used for increasing the creepage distance between the metal contact element and the outside. In the process of designing the insertion end matching structure of the high-voltage connector, the influences of the creepage distance and air blockage on high voltage resistance indexes are comprehensively considered, and the creepage distance is increased, the air blockage is realized and the need of ultrahigh voltage performance is met through a plurality of 360-degree arc-shaped convex ring superposed interference structures and end surface rubber ring extrusion sealing structures under the condition of limiting space.
Description
Technical field
The utility model relates to the connector technique field, and being specifically related to a kind ofly can increase creepage distance, realizes the novel high-pressure connector mating side fit structure of air block.
Background technology
Domestic use superhigh pressure dynamic connector mainly relies on import, but because of the import cycle long, cost an arm and a leg, limited the application of this product, at present mainly be to be used in the model development of some up-to-date high-end products.Present high-voltage electric connector adopts the cone boss on the interfacial seal pad to increase creepage distance and air block usually, and this structure only satisfies ten thousand volts of following high pressure demands.The withstand voltage index request of high-tension apparatus constantly promotes, and overall dimension requires constantly to reduce, and the high voltage performance of mating connector has been proposed requirements at the higher level.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of high-tension connector mating side fit structure is provided, this high-tension connector mating side fit structure has been taken all factors into consideration the influence to high pressure resistant index of creepage distance, air block in design process, can increase the creepage distance of high-tension connector, realize air block, satisfy the superhigh pressure performance requirement.
To achieve the above object of the invention, the technical scheme that the utility model adopted is: a kind of high-tension connector mating side fit structure is provided, comprises plug and socket; The housing of described plug and socket all adopts insulating material to make; Described plug interference is inserted in the socket; Described plug and socket connection is provided with the Metal Contact part; It is characterized in that: the excircle of the end in the described plug insertion socket is provided with the circular-arc bulge loop that is used to increase Metal Contact part and extraneous creepage distance.
According to high-tension connector provided by the utility model mating side fit structure, it is characterized in that: described circular-arc bulge loop be arranged two at least in parallel.
According to high-tension connector provided by the utility model mating side fit structure, it is characterized in that: also be provided with the rubber ring that is used to block the inside and outside creepage passage of connector between the described plug and socket.
In sum, high-tension connector provided by the utility model mating side fit structure has following advantage:
1, simple in structure, overall dimensions is little, high-voltage resistance capability is strong, manufacturing is easy to use, connection is reliable;
2, reduce the connector overall dimensions, improve the connector high-voltage resistance capability, improve the performance of technical process of part;
3, under the condition of restriceted envelope, utilize a plurality of 360 ° of circular-arc bulge loop stack interference structures and end face rubber ring extruded sealing structure to increase the creepage distance of high-tension connector, realized air block, satisfy the demand of superhigh pressure performance.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done and to be described in detail:
As shown in the figure, this high-tension connector mating side fit structure comprises plug 3 and socket 1; The housing of described plug 3 and socket 1 all adopts insulating material to make; Described plug 3 interference are inserted in the socket 1; Described plug 3 and socket 1 connection are provided with Metal Contact part 2; It is characterized in that: the excircle that described plug 3 inserts the end in the sockets 1 is provided with the circular-arc bulge loop that is used to increase Metal Contact part 2 and extraneous creepage distance.Described circular-arc bulge loop be arranged two at least in parallel.Also be provided with the rubber ring 4 that is used to block the inside and outside creepage passage of connector between described plug 3 and the socket 1.
During use, plug 3 interference are inserted in the socket 1, and the mating surface that a plurality of 360 ° of circular-arc bulge loops on the plug 3 and socket 1 interference distortion back form has increased Metal Contact part 2 and extraneous creepage distance; Socket 1 compressing rubber circle 4 produces distortion, the inside and outside creepage passage of blocking-up connector.
The utility model is not limited to above-mentioned example, in claims of the present utility model institute restricted portion, and various distortion that those skilled in the art can make without creative work or revise the protection that all is subjected to this patent.
