Description
Technical field
The present invention relates to a kind of elastic triggering device for electrically connecting.
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 between rack, system and subsystem to electrically connect and signal of telecommunication transmission, 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
Connect device and claim socket, free-end electric connector claims plug to constitute.Electric connector is by housing, insulator, the big elementary cell of contact three
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 connection and separates.Tail accessory is used for protecting injury-free at wire and contact termination being used in combination
In fixing cable.Housing also has certain electromagnetic shielding action, and electric connector makes plugs and sockets integrally contact by housing connection,
Connected mode has：Threaded, 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. constitute.In order 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 gold-plated reaches the little and etch-proof purpose of contact resistance using silver-plated.Inserted by contact pin
In jack, plug hole this body structure is relied on to reach the connection conducting of contact pin plug hole to the power of one radial direction of contact pin.Contact tail end with
Wire or the type of attachment of 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 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 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 rely on 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 contact pin is in contact centering in passive
Connection, mainly leans on the radial force of jack one direction applying come connected, and the version due to jack all has actual contact
Face is little, because causing reliability to reduce as mechanical wear or elasticity are deteriorated after multiple plug, there is possibility generation Joint failure
Risk.
Content of the invention
The technical problem to be solved is to provide one kind to realize being reliably connected, and simple structure, easy to use,
The long-lived arrangement for resilient contacting for electrically connecting.
The present invention solves the technical scheme that adopted of above-mentioned technical problem：A kind of Elastic Contact dress for electrically connecting
Put, including hollow bolt and copper cylinder push rod, described copper cylinder push rod is located in described hollow bolt, institute
The copper cylinder push rod that states is two-part ledge structure, and the leading portion enlarged diameter section of described copper cylinder push rod stretches out described
The head of hollow bolt and the top of described copper cylinder push rod is the sphere curved surface for abutting with positive metal contact,
After being set with helical spring and described copper cylinder push rod on the back segment reduced diameter section of described copper cylinder push rod
Section reduced diameter section stretches out the afterbody of described hollow bolt, and the afterbody of described hollow bolt is radially inwardly provided with a coil spring
Spacing ring, described helical spring is located between step and the described spring retainer ring of described copper cylinder push rod, institute
The reduced diameter section afterbody of the copper cylinder push rod that states is provided with sealing nut, and the afterbody of described hollow bolt is arranged with spiral shell
Mother, forms the annular groove for coordinating with external perforation between the head of described hollow bolt and described nut, described copper
Matter cylinder push rod is connected with external power source by wire.
Described sealing nut with diameter greater than the internal diameter of described hollow bolt and outer less than described hollow bolt
Footpath.
