Description
Technical field
The utility model relates to a kind of connector assembly that is used for anti-electric current or signal.
Background technology
The voltage that plug and socket bore that is used for electric field at present is increasing; In order to guarantee the insulation property of plug and socket; Concerning the plug and socket of many contacts; Needing increases the creepage distance between the adjacent contact, concerning the plug and socket that are provided with metal shell, also need increase the creepage distance between contact and the housing.A kind of plug and socket of the prior art, plug comprises plug casing, is set with contact pin through pin insulator in the endoporus of plug casing; Contact pin stretches out the front end face of pin insulator; Have the space that supplies socket to stretch between the endoporus of contact pin and plug casing, socket comprises Socket casing, is provided with jack through the socket insulator in the endoporus of Socket casing; The front portion of socket insulator is coated on the leading portion of jack; Have the annular space that is installed with plug casing between the outer peripheral face of socket insulator and the Socket casing, contact pin inserts in the jack when pegging graft, and plug casing is plugged in the space between Socket casing and the socket insulation; Insulate through the socket insulator between the contact pin that plugs together mutually, jack and the plug insulation; Owing to be in the state of peeling off between socket insulator and the plug casing, plug together between rear socket insulator and the plug casing and can retain some air, under high pressure these air may be caused decreasing insulating between plug and the socket by ionization.
The utility model content
The purpose of the utility model is to provide a kind of high voltage withstanding connector assembly, to improve the insulation property of connector assembly.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of high voltage withstanding connector assembly; Comprise the plug and socket that the front end through separately plugs together mutually, plug comprises soft pin insulator, is installed with contact pin in the endoporus of pin insulator; Socket comprises the socket insulator of hard; Be installed with jack in the endoporus of socket insulator, have the gap of the leading portion insertion that supplies the socket insulator between the endoporus leading portion of pin insulator and the leading portion of contact pin, the hole wall of the endoporus leading portion of pin insulator is the enlarging conical surface forward; The front portion of socket insulator is coated on the leading portion of jack; The endoporus leading portion of socket insulator and the leading portion snug fit of jack, the outer peripheral face of the front end of socket insulator are the friction tight conical surface that coincide of the hole wall with the endoporus leading portion of pin insulator, on the hole wall of the endoporus leading portion of pin insulator or the outer peripheral face of the front end of socket insulator be provided with the convexity of annular.
The cross section of described convexity is bad arc.
Described convexity is arranged on the endoporus hole wall of pin insulator.
Described convexity is two, is arranged on the endoporus hole wall of pin insulator at interval.
The hole wall of the endoporus leading portion of the pin insulator of the utility model is the conical surface of enlarging towards front end; The outer peripheral face of the front end of socket insulator is the friction tight conical surface that coincide of the hole wall with the endoporus leading portion of pin insulator, and when plug and socket plugged together, the socket insulator of hard was plugged in the endoporus of soft pin insulator; Both tight fits; Can the air in the endoporus of pin insulator be extruded, and have the convexity of annular on the endoporus hole wall of pin insulator or on the outer peripheral face of socket insulator, when convexity is arranged on the pin insulator; Convexity is exactly soft; Plug together the back convexity at pin insulator and socket insulator and be compressed, compressed convexity prevents the mating face seal of pin insulator and socket insulator between both mating surfaces of air entering; When convexity was arranged on the outer peripheral face of socket insulator, convexity was exactly a hard, and plugging together the back convexity at pin insulator and socket insulator will the extrusion pin insulator; Make the inner hole wall of pin insulator and the distortion of this convexity cooperation place want big than other positions; Thereby, prevent that air from getting between both mating surfaces, because air is extruded with the mating face seal of pin insulator and socket insulator; Do not exist because the problem of the decreasing insulating of the connector assembly that air is caused by ionization; Therefore the insulation property of the utility model are better, and high voltage performance is good, simultaneously; The existing socket insulator part that is packaged in the jack outside in the contact pin after plugging together and the outside of jack has the pin insulator part that is positioned at the contact pin outside again; And the air between these two parts is extruded again, and the creepage distance between contact pin, jack and the pin insulator periphery part in addition after therefore plugging together is bigger, and the insulation property of whole connector assembly are better.
