Description
Technical field
The present invention relates to a kind of conductive connecting device more particularly to a kind of jack contacts and electric connector.
Background technique
Conventional jack contact is divided into contact pin and jack, jack be divided into again by structure open pore (at aperture with contact pin shape
At Elastic Contact), coil spring hole (internal coil spring silk and contact pin formed Elastic Contact), string of a hat hole (the internal string of a hat and contact pin formation bullet
Property contact) etc..
Existing annular contact part be all by forming Elastic Contact between contact pin and jack elastomer or elastic construction,
To realize electric signal or electric current transmission.Between contact it is reliable, be steadily contacted by between contact pin and jack elastomer
Contact pressure guarantees that contact pressure is bigger, is bonded between the two tighter, and contact resistance is smaller.But contact pressure is bigger, contact pin
Contact engaging and separating force when being plugged with jack increases, so that comfort when using declines, and is increasing contact pin and elastomer
After contact pressure, frictional force between the two increases, and causes the abrasion of contact when plug to aggravate, the contact after a period of time
It can decline, contact resistance increases, and declines the transmission quality of signal, and temperature rise when transmitting electric current increases.And it is small in contact pressure
When, comfort of the contact in plug be good, abrasions of contact surfaces less, service life it is high, but contact resistance is big,
The transmission performance of signal or electric current is poor, and the contact stabilization in severe dynamic environment is poor.Therefore, contact pin passes through with jack
Elastomer or elastic construction Elastic Contact have more inconvenience in actual use.
Summary of the invention
The purpose of the present invention is to provide a kind of jack contacts, pass through elasticity knot to solve existing jack contact
Structure Elastic Contact causes inconvenience in use.
In order to solve the above-mentioned technical problem, jack contact of the invention adopts the following technical scheme that a kind of jack contact
Part, including ontology, the ontology include fixed part and can relatively fixed part be moved forward and backward movable part, further include passing through
The metal braided sheath that first connecting pin is fixedly connected with movable part, is fixedly connected by second connection end with fixed part, institute
The inner hole for stating metal braided sheath constitutes the grafting space being inserted into from the front to the back for contact pin contacting piece；Movable part was moving backward
Have in journey and drives the first connecting pin towards second connection end movement so that metal braided sheath internal diameter becomes larger to more than contact pin connects
The plug position of contact element outer diameter, movable part has in movement forward drives the first connecting pin mobile backwards to second connection end
So that metal braided sheath internal diameter gradually becomes smaller to less than the working position of the outer diameter of contact pin contacting piece.
The fixed part includes the installation cavity that front and back extends, and movable part is the sliding sleeve being set in outside installation cavity, and first
Connecting pin is fixedly connected on the inner peripheral surface of sliding sleeve, and second connection end is fixedly connected on the inner peripheral surface of installation cavity.
The ontology further includes in the movable inner sleeve that interference is inserted into sliding sleeve and fixation that interference is inserted into installation cavity
Set, the first connecting pin, which is pressed on, to be realized between sliding sleeve and movable inner sleeve and is fixedly connected with sliding sleeve, and second connection end is pressed on peace
It behave affectedly and fixes and realize between inner sleeve and be fixedly connected with installation cavity.
The inner peripheral surface of the sliding sleeve is equipped with for cooperating with the front end block of installation cavity to move backward most to sliding over
The stopping surface that big stroke is limited, at installation cavity front end and block face contact, sliding sleeve is located at plug position.
The ontology further includes the spring for being supplied to the elastic force that movable part moves backward.
Electric connector of the invention adopts the following technical scheme that a kind of electric connector, including jack contact, the jack
Contact includes ontology, ontology include fixed part and can the movable part that is moved forward and backward of relatively fixed part, further include passing through
The metal braided sheath that first connecting pin is fixedly connected with movable part, is fixedly connected by second connection end with fixed part, institute
