Description
Technical field
The present invention relates to a kind of conductive connecting device, especially a kind of electric coupler component.
Background technology
With the electronic equipments such as the continuous development of power communication cause, mobile communication just towards miniaturization, integrated development,
And electric connector is played a very important role as the interface of electronic equipment electric signal relaying transport.Electric connector generally comprises
Plug, socket and for connection plug and the coupling nut of socket, plug includes plug casing, and socket includes Socket casing,
Plug casing and Socket casing are respectively equipped with contact pin, jack, are locked and connected by coupling nut in plug and socket grafting.
In order to ensure the reliability and stability of connection, generally required when plug and socket is to being inserted into grafting position to connection
Nut carries out axial limiting to avoid plug and socket moves axially in use and causes Joint failure.Existing connection
The coupling nut of device generally can carry out by snap ring or lock-screw or in the locking steel ball of radial floating axial locking limit
Position, realizes that the spacing connector disassembly process of coupling nut is cumbersome in these connectors by snap ring or lock-screw,
Need to dismantle snap ring or lock-screw, although and, connector construction simple using the connector disassembly process of locking steel ball
It is sufficiently complex, improve manufacture cost.
The content of the invention
It is an object of the invention to provide a kind of electric coupler component, to solve existing electric connector dismounting inconvenience,
The problem of coupling nut locking mechanism is complicated.
In order to solve the above-mentioned technical problem, electric coupler component of the invention adopts the following technical scheme that：One kind is electrically connected
Device assembly, including plug, socket and coupling nut, the electric coupler component further include axial for being carried out to coupling nut
Spacing locking silk is locked, the locking silk is open ring structure, and receiving is respectively provided with Socket casing and coupling nut
The socket annular groove and nut annular groove of silk are locked, socket annular groove and nut annular groove opening at grafting position are opposite, the locking silk tool
Have Socket casing and coupling nut spinning in place when the radial direction spreading and cell wall with socket annular groove and nut annular groove contacts respectively
To carry out the locking position of axial locking to coupling nut and when Socket casing and coupling nut are axially opposing mobile by nut
The cell wall extruding of annular groove and radial contraction simultaneously skid off nut annular groove and release to the solution lock-bit of coupling nut axial direction locking.
The locking silk is circular wire, and the nut annular groove is arc groove.
The periphery of the plug casing is equipped with sealing ring mounting groove of the opening towards Socket casing, pacifies in sealing ring mounting groove
Equipped with carbon seal ring, carbon seal ring, which has, to be used for when plug and socket be located at grafting position and the end top of Socket casing
The top pressure mating surface that means of press seals coordinates.
The coupling nut and Socket casing are locked by motion thread and connected.
The plug and socket further includes the jack insulator being respectively arranged in plug casing and Socket casing and contact pin is exhausted
Edge body, jack insulator and contact pin insulator are ceramic material.
The electric coupler component of the present invention is spacing by locking the silk locking axial to coupling nut progress, and locking silk has
Socket casing and coupling nut spinning in place when radially outward spreading and slip into nut annular groove to coupling nut carry out axial lock
Locking position only and radially-inwardly shunk when Socket casing and coupling nut are axially opposing mobile and skid off socket annular groove solution
Except the solution lock-bit to coupling nut axial direction locking, locking silk so in grafting can be under the extruding of the inner peripheral surface of coupling nut
Automatic to shrink, when plug and socket is located at grafting position, the opening of socket annular groove and nut annular groove is opposite, and locking silk can be automatic
Spreading is simultaneously slipped into nut annular groove so as to coordinate the axial direction realized to coupling nut by the both sides cell wall block with nut annular groove
Locking is spacing, and in dismounting, rotatable connection nut exits, the cell wall extruding locking silk of nut annular groove, work of the locking silk in extruding force
Skidded off with lower to contract and from nut annular groove, release it is spacing to the axial locking of coupling nut, so as to fulfill plug, socket
Separation, this elasticity by locking silk itself realizes the mode connector grafting to the locking of coupling nut and unlock
It is very convenient with disassembly process, while the structure of connector is also fairly simple, manufacture cost is relatively low.
Further, it is circular wire to lock silk, and nut annular groove is arc groove, so the nut in dismounting on coupling nut
The side wall of annular groove can to locking silk to be conducive to lock the radial contraction of silk towards the power in center of circle direction where arc cell wall, be easy to
Release the locking to coupling nut.
Further, the resistance to height of electric connector is improved between plug casing and Socket casing by carbon seal ring sealing
Warm, radiation-resistant performance so that the electric connector can be applied in the applicable field of nuclear power, aerospace and other bad environments
Close, ensure that the safety and reliability being conductively connected.
Further, since the natural resiliency of carbon seal ring is smaller, Socket casing and connection are connected by motion thread
Nut can increase the coupling mechanism force between coupling nut and Socket casing, ensure that Socket casing is pressed in carbon seal ring, carry
High sealing effect.
Further, jack insulator and contact pin insulator are that ceramic material can adapt to the severe rings such as the high radiation of high temperature
Border, is hardly damaged, and service life is longer.
