Description
Technical field
This utility model is related to a kind of elastic triggering device for electrical connection.
Background technology
At present, electric connector is widely used in Aeronautics and Astronautics, military dress as one of element for connecting electric wiring
Standby, communication, computer, locomotive, automobile, electronic equipment, the industrial field such as machine tool and household electrical appliance.Mainly in power supply
With electrical appliance, device and component, component and play a part of to electrically connect and signal of telecommunication transmission between rack, system and subsystem, and
And between holding system and system, there is no the change of distorted signals and energy loss.Connect as complete circuit system electrical is constituted
One of required base components are connect, the contour structures of electric connector are mainly circular and rectangle, and electric connector is electrically connected by fixing end
Connecing device claims socket, free-end electric connector to claim plug to constitute.Electric connector is by housing, insulator, three big elementary cell of contact
Composition.1. housing-- electric connector housing refers to the shell of plugs and sockets, coupling nut, tail accessory.Shell effect is to protect
The shield electrical connector interior part such as insulator and contact is not damaged.Positioning spline above ensures that plug is positioned with socket.
Coupling nut is used for connector assembly and connects and separate.Tail accessory is used to protect injury-free at wire and contact termination being used in combination
In fixed cable.Housing also has certain electromagnetic shielding action, and electric connector makes plugs and sockets integrally contact by housing connection,
Connected mode has：Threaded connection, bayonet connection, kayser connection, plug-type connection, direct insertion connection etc.；2. insulator-by filling
Contact pin insulator, dress jack insulator.Interface sealing body, grommet etc. are constituted.To keep contact pin jack on setting position,
And make between each contact and mutual electric insulation between each contact and housing.3. contact-i.e. contact pin jack is to be electrically connected
Device key element is connect, it directly affects the reliability of electric connector.Contact pin jack is mostly using the elasticity that electric conductivity is good
Cu alloy material is processed, and surface reaches using plating vermeil that contact resistance is little and etch-proof purpose.Inserted by contact pin
In jack, by this body structure of plug hole to one radial direction of contact pin power reach contact pin plug hole connection conducting.Contact tail end with
The type of attachment of wire or wiring board：Crimping, welding, solderless wrapped connection, screw fixation etc..
Contact is the core parts that electric connector realizes that " electricity " connects, at present, typically all by positive contact and the moon
Property contact composition contact it is right, by yin, yang contact plug together complete electrical connection.Its positives contact is hard parts,
Commonly referred to as contact pin, which is cylindrically shaped such as circle contact pin, square column type such as square contact pin or pancake such as inserted sheet.Positive contact one
As be made up of pyrite, phosphor bronze.Female contact is jack, be contact to vital part, it by elastic construction with insert
There is elastic deformation when pin is plugged together and produce elastic force and close contact is formed with positive contact, i.e., reach by applying radial force
Make contact to the purpose for connecting, complete connection.The structure species of jack are a lot, have cylinder type such as to split groove, necking, have tuning-fork-type,
Cantilever beam type, folding type, box-like such as square jack, and hyperboloid wire spring socket etc..Because it is passive that contact pin is in in contact
Connection, the radial force for mainly applying by jack one direction connecting, because all there is actual contact in the version of jack
Face is little, because causing reliability to reduce as mechanical wear or elasticity are deteriorated after multiple plug, there is possibility and Joint failure occurs
Risk.
The content of the invention
Technical problem to be solved in the utility model is to provide one kind and can realize being reliably connected, and simple structure, uses
It is convenient, the long-lived arrangement for resilient contacting for electrical connection.
This utility model solve the technical scheme that adopted of above-mentioned technical problem for：A kind of Elastic Contact for electrical connection
Device, including hollow bolt and copper cylinder push rod, described copper cylinder push rod are located in described hollow bolt,
Described copper cylinder push rod is two-part ledge structure, and the leading portion enlarged diameter section of described copper cylinder push rod stretches out institute
It is the spherical song abutted with positive metal contact at the top of the head of the hollow bolt stated and described copper cylinder push rod
Face, is set with helical spring and described copper cylinder push rod on the back segment reduced diameter section of described copper cylinder push rod
Back segment reduced diameter section stretches out the afterbody of described hollow bolt, and the afterbody of described hollow bolt is radially inwardly provided with a circle bullet
Spring spacing ring, described helical spring are located between the step and described spring retainer ring of described copper cylinder push rod,
The reduced diameter section afterbody of described copper cylinder push rod is provided with sealing nut, and the afterbody of described hollow bolt is arranged with spiral shell
Mother, forms the annular groove coordinated with external perforation, described copper between the head and described nut of described hollow bolt
Matter cylinder push rod is connected with external power source by wire.
Described sealing nut it is with diameter greater than the internal diameter of described hollow bolt and outer less than described hollow bolt
Footpath.
The distance between the step of described copper cylinder push rod and described spring retainer ring are equal to or slightly less than institute
Length of the helical spring stated under zero load.
The diameter of the leading portion enlarged diameter section of described copper cylinder push rod is equal to or slightly less than described hollow bolt
