Abstract
The invention relates to differential contact double pins and a corresponding socket and a plug thereof, wherein, each pin comprises an outer pin, a central hole, a pin insulator and a wire pressing insulator are mounted in each outer pin, and a snap ring is mounted outside each outer pin. A metal pipe-like inner wire clamp is spirally assembled in a tail hole of each outer pin, a front end socket of each metal pipe-like inner wire clamp is used for pressing and fixing the wire pressing insulator, and the tail section of each metal pipe-like inner wire clamp is exposed out of the tail end of the outer pin. As the metal pipe-like inner wire clamp is spirally assembled in the tail hole of each outer pin, the front end socket of each metal pipe-like inner wire clamp is used for pressing and fixing the wire pressing insulator, thereby leading the assembly relationship between each metal pipe-like inner wire clamp and each outer pin to be changed to a structure which can be replaced and detached; therefore, the pins can be repaired and repeatedly used, and the using cost can be saved.
Description
Technical field
The present invention relates to a kind of differential contact double pins and corresponding socket and plug thereof, be used for the transmission of differential signal, belong to the electroporation field.
Background technology
Differential contact even is widely used in differential signal and connects the transmission occasion.In the outer pin of differential contact double pins the line ball insulator is installed all, the line ball insulator needs fixing reliably.At present, the line ball insulator of existing a kind of contact pin is to press solidly by wire clamp in one section tubulose of plug-in mounting in the outer backshank hole, be provided with annular space between wire clamp and the outer pin inwall in the tubulose, the outer pin wall thickness of corresponding position is attenuate specially, in the corresponding insertion of the shielding netting wire annular space with cable during use, with special-purpose Crimping Pliers the outer pin of thin-walled portion is pressed solidly in tubulose on the wire clamp again, realize being connected of the shielding of fixing, connector of line ball insulator and cable and connector.The problem of this mode is mainly in following several respects: at first be to reuse, because the disposable sex change of outer pin wire clamp in tubulose is crimped on, as long as make contact pin go wrong, can only scrap replacing, cause waste and increase use cost; Secondly, pressing solidly in the tubulose between wire clamp and the line ball insulator is unreliable, when pressing solidly, as long as have insufficient pressure and loosening situation in the tubulose between wire clamp and the line ball insulator, just can't remedy, this gives to manipulate and has brought certain difficulty and difficulty, also can have influence on the quality of signal transmission.This mode makes the sealing between interior wire clamp of tubulose and the outer pin also have certain problem.
Summary of the invention
Task of the present invention provides a kind of differential contact double pins, solving the existing not re-usable problem of contact pin, and improves in the tubulose the quality that presses solidly between the wire clamp and line ball insulator.
For finishing above-mentioned task, technical scheme of the present invention is to adopt a kind of differential contact double pins, comprise outer pin, centre bore and line ball insulator are installed in the outer pin, wire clamp in tubular metal of the uropore inside spin of pin assembling outside, the front end of wire clamp is used for fixedly line ball insulator of crimping in the tubular metal, the rear of wire clamp exposes outer backshank end in the tubular metal, the periphery of wire clamp is provided with a circle convex ring body in outer backshank port in tubular metal, convex ring body and outside be provided with O-ring seal between the backshank port.
The backshank end parts was arranged with wire clamp outside the tubular type outside the rear of wire clamp exposed in tubular metal.
The surface of backshank end parts was provided with the annular knurl face outside the rear of wire clamp exposed in tubular metal.
Corresponding with contact pin, the present invention also correspondence has adopted a kind of differential contact even connector plug, in the short insulator in plug casing contact pin is installed, contact pin comprises outer pin, centre bore and line ball insulator are installed in the outer pin, wire clamp in tubular metal of the uropore inside spin of pin assembling outside, the front end of wire clamp is used for fixedly line ball insulator of crimping in the tubular metal, the rear of wire clamp exposes outer backshank end in the tubular metal, the periphery of wire clamp is provided with a circle convex ring body in outer backshank port in tubular metal, convex ring body and outside be provided with O-ring seal between the backshank port.
The backshank end parts was arranged with wire clamp outside the tubular type outside the rear of wire clamp exposed in tubular metal.
The surface of backshank end parts was provided with the annular knurl face outside the rear of wire clamp exposed in tubular metal.
Corresponding with contact pin, the present invention also correspondence has adopted a kind of differential contact even connector body, in the short insulator in Socket casing contact pin is installed, contact pin comprises outer pin, centre bore and line ball insulator are installed in the outer pin, wire clamp in tubular metal of the uropore inside spin of pin assembling outside, the front end of wire clamp is used for fixedly line ball insulator of crimping in the tubular metal, the rear of wire clamp exposes outer backshank end in the tubular metal, the periphery of wire clamp is provided with a circle convex ring body in outer backshank port in tubular metal, convex ring body and outside be provided with O-ring seal between the backshank port.
The backshank end parts was arranged with wire clamp outside the tubular type outside the rear of wire clamp exposed in tubular metal.
The surface of backshank end parts was provided with the annular knurl face outside the rear of wire clamp exposed in tubular metal.
Because the present invention's uropore inside spin of pin has outside assembled wire clamp in the tubular metal, the front end of wire clamp is used for fixedly line ball insulator of crimping in the tubular metal, make the assembly relation between interior wire clamp of tubular metal and the outer pin become replaceable and demountable structure, thereby, contact pin of the present invention can be repaired and use repeatedly, can save use cost.In addition, tubular metal interior lines clamp screw is assemblied in the contact pin, makes its thrust to the line ball insulator to adjust, and can improve the reliability of contact pin assembling and work.The periphery of wire clamp is provided with a circle convex ring body in outer backshank port in tubular metal, convex ring body and outside O-ring seal is set between the backshank port, the pine that both can prevent wire clamp in the tubular metal moves back, and can also play sealing function, has further improved the reliability of contact pin assembling and work.The present invention's wire clamp outside the sheathed tubular type of backshank end parts outside the rear of wire clamp exposes in tubular metal, the shielding netting wire of cable can be put into annular space between the two, press solidly with special-purpose Press Plier, make the contact idol hold the good shielding of 360 degree by line ball in outer pin and the tubular metal.The surface of backshank end parts was provided with the annular knurl face outside the rear of wire clamp exposed in tubular metal, can increase frictional force, prevented that the pine of shielding conductor from moving back.
