Description
Technical field
The utility model belongs to technical field of electric connectors, and the electric connector contact that proposes a kind of radial elastic application of force is right.
Background technology
Electric connector is as one of element that connects electric wiring, its purposes is to play a part to be electrically connected and signal transmits between power supply and electrical appliance, device and assembly, assembly and rack, system and subsystem, and the variation of distorted signals and energy loss does not take place between maintenance system and the system.Connect one of essential base components as constituting the complete circuit system electrical, be widely used in fields such as Aeronautics and Astronautics, military equipment, communication, computer, locomotive, automobile, electronic equipment, industrial machine tool and household electrical appliance.
The contour structures of present electric connector mainly is circle and rectangle, and electric connector is by fixed end electric connector (to call socket in the following text), and free-end electric connector (to call plug in the following text) is formed.Electric connector is made up of housing, insulator, contact three big elementary cells.1. housing---electric connector housing is meant shell, coupling nut, the afterbody annex of plugs and sockets.The shell effect is that protection insulator and contact electric connector inner bodies such as (common names of contact pin jack) are not damaged.Top positioning spline guarantees plug and socket location.Coupling nut is used for connector assembly and connects and separate.It is injury-free and be used for fixing cable that the afterbody annex is used for guardwire and contact termination place.Housing also has certain electromagnetic shielding action, and electric connector connects by housing makes the whole contact of plugs and sockets, and connected mode has: be threaded, bayonet socket (fast) connection, kayser connection, plug-type connection, direct insertion connection etc.; 2. insulator---by dress contact pin insulator, dress jack insulator.Compositions such as interface sealing body, grommet.In order to keeping contact pin jack on desired location, and make between each contact and each contact and housing between electric insulation mutually.3. contact (also being contact)---contact pin jack is the contact general name, and contact pin jack is the electric connector key element, and it directly affects the reliability of electric connector.Contact pin jack adopts electric conductivity better elastic Cu alloy material machine to add mostly and forms, and the silver-plated gold-plated little and etch-proof purpose of contact resistance that reaches is adopted on the surface.Insert in the jack by contact pin, rely on this body structure of plug hole to reach the connection conducting of contact pin plug hole for power radially of contact pin.The type of attachment of contact tail end and lead or wiring board: crimping, welding, solderless wrapped connection; Screw (cap) is fixing etc.
Contact is that electric connector is realized the core parts that " " connects, and it is right to be that the rigidity all be made up of positive contact and negative contact contacts at present, finishes electrical connection by plugging together of yin, yang contact.Wherein positive contact is a hard parts, generally is called contact pin, and it is shaped as cylindrical (circle contact pin), square column type (square contact pin) or pancake (inserted sheet).Positive contact is generally made by brass, phosphor bronze.Negative contact is a jack, it is the right vital part of contact, its rely on elastic construction when plugging together, strain to take place with contact pin and produce elastic force and positive contact form tight the contact (by apply radial load reach make contact to purpose of connecting), finish connection.The structure kind of jack is a lot, and cylinder type (splitting groove, reducing), tuning-fork-type, cantilever beam type (vertically fluting), folding type (vertically slotting 9 fonts), box-like (square jack) and hyperboloid wire spring socket etc. are arranged.
Because being in contact centering, contact pin is dynamically connected, mainly be to reach purpose of connecting to the radial load that applies by the jack folk prescription, but the version of the sort of jack all exists the actual contact face little at present, and repeatedly the plug back is because mechanical wear causes the elasticity variation, radial load reduces, friction causes gold-plated silver coating wearing and tearing, and electric property and reliability reduce, and existence may connect the risk of inefficacy.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is that the electric connector contact of a kind of radial elastic application of force of proposition is right, make it can improve mechanical performance and reliability that electric connector connects, by flexible member to the contact to applying radial pressure, it is closely contacted to reach the purpose of electrical connection, not only big but also pressure is bigger than the contact-making surface that originally applied radial load merely by plugging together of yin, yang contact, contact resistance is littler, because contact-making surface does not have mechanical friction, can improve contact right useful life and security reliability greatly.
Adopt following technical scheme for finishing foregoing invention purpose the utility model:
A kind of electric connector contact of the radial elastic application of force is right, and described electric connector is made up of plug body and socket; Described plug body has plug body housing and conductive contact piece A; Described socket has socket housing and conductive contact piece B; Described conductive contact piece A and conductive contact piece B correspondence are provided with that to constitute contacting of electric connector right; Same electric connector by some contacts to forming; In described socket, be provided with in order to prevent that conductive contact piece B from departing from the fixed leg of contact position; End at described socket is provided with usefulness so that contact compresses the operating key that realization electrically connects to conducting position; Be connected with removable insulation board with described operating key, the corresponding contact of described removable insulation board is a plurality of to being set to; Away from being provided with in order to elasticity longitudinal force flexible member to be provided of operating key one end, described flexible member links to each other with removable insulation board.
The electric connector contact of a kind of radial elastic application of force that the utility model proposes is right, mechanical performance and reliability that electric connector connects have been put forward, by flexible member to the contact to applying radial pressure, it is closely contacted to reach the purpose of electrical connection, not only big but also pressure is bigger than the contact-making surface that originally applied radial load merely by plugging together of yin, yang contact, contact resistance is littler, because contact-making surface does not have mechanical friction, can improve contact right useful life and security reliability greatly.
