Description
Technical field
The present invention relates to a kind of electrical connector, especially a kind of 380V and following voltage connector.
Background technology
Electrical connector is a kind of device applied in the connection of electricity widely, and it can realize the connection of electricity very easily, and can disconnect at any time, the electrical connector of current use comprises joint and socket, joint is provided with inserted link, socket is provided with jack, inserted link is placed in socket by jack, described inserted link top is connected with ammeter, plug side is connected with electric wire, when circuit malfunctions, realizes power-off by electrical connector, work is convenient, safe and effective; In order to reduce the contact resistance between plug and ammeter string holes, often need the diameter of socket connector plug to increase thick, can with the closely cooperating of ammeter string holes, reduce contact resistance, improve conductance, meet temperature increase requirement; But such connector is when more rewiring at needs, because socket connector plug coordinates with ammeter string holes too tight, easily there is the problems such as plug difficulty, increasing burden to staff, be not easy to operation.
For solving the problem, application number be 201410257812.4 Chinese patent disclose a kind of electrical connector, it comprises joint and socket, joint is provided with contact pin, and socket center offers jack, is provided with the thimble supported mutually with contact pin in jack, the diameter of the diameter contact pin of thimble is identical, the interference of thimble portion is provided with rubber fastener, and jack is provided with locating surface, jack is installed with the first plug; Be set with in contact pin and along the cylindrical shell fragment of joint axial sliding movement, shell fragment can be evenly provided with multiple oblique spacer stretched out outside contact pin.Electrical connector electrical connection good stability of the present invention, and the plug of joint is convenient, improves the useful life of connector.But so electric plug only can ensure the connective stability of plug and ammeter, cannot ensure the close contact of contact pin and ammeter, reduce resistance, to ensure the fail safe of equipment.
Therefore, work out a kind of structure simple, and plug and ammeter close contact can either be ensured, improve conductance, meet temperature increase requirement and can realize again plug plug to be easy to connector be one of major issue of needs solution at present.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of structure simple, and can either ensure plug and ammeter close contact, improves conductance, meets temperature increase requirement and can realize again the easy 380V of plug plug and following ammeter box connector.
Technical scheme: for achieving the above object, the invention provides a kind of 380V and following voltage connector, comprise base, plug, described plug is embedded on the plug hole of base, described plug comprises syringe needle, jacking block, spring structure, briquetting, connector, described syringe needle is that described jacking block is located at the shaft core position of syringe needle bottom by the metal bar of more than four pieces or four pieces circumferentially around forming column construction, and described spring structure two ends are connected with jacking block and briquetting respectively; Described connector is located at below briquetting, and described connector side is provided with waterproof, is provided with plug control hole above waterproof, the position between the corresponding briquetting in described plug control hole position and connector; Described base is provided with fixture, and described fixture comprises operating handle, backstay, and described operating handle is fixed on base both sides by bearing pin; Base is respectively equipped with base connecting hole, plug is built in base plug hole, and described waterproof is corresponding with base connecting hole position; Described backstay top is contacted with briquetting by plug control hole, and backstay tail end is connected with operating handle by eccentric wheel, and described backstay connects with eccentric wheel outer rim, and operating handle connects with the eccentric wheel center of circle.Structure of the present invention is simple, by column construction syringe needle is set to and the metal bar of more than four pieces or four pieces is circumferentially formed, thus by the spacing between adjustment metal bar to control the diameter length of syringe needle, can closely cooperate with the jack in ammeter box, also can reduce resistance while improving electrical efficiency, improve the fail safe of equipment; Again because described jacking block is located at the shaft core position of syringe needle tail end, and jacking block is connected with spring structure, briquetting successively, during operation, by lift operating handle, realize backstay to briquetting upwardly, drive jacking block upwardly by spring structure, the metal bar be located at around it is outwards promoted, thus realize the object expanding needle diameter, simple to operate, beneficial effect is obvious.
