Abstract
The utility model relates to a kind of cylindrical hermetically-sealed electrical connector, comprise housing, insulating base and contact pin, it is characterized in that: described insulating base is glass insulation seat, described housing is metal shell, described glass insulation seat sealing by fusing is fixed in described metal shell, described contact pin passes described glass insulation seat when described glass insulation seat molten condition, and is fixed in described glass insulation seat.After using metal shell and glass insulation seat, every electric property and sealing property are more than ten times of original plastic casing connector, and solving original plastic casing connector installs loaded down with trivial details, the easy shortcoming such as aging in adverse circumstances, reaches that resistance to pressure is good, air-tightness is stablized, tensile strength large and the object that thermal adaptability is strong.
Description
Technical field
The utility model relates to electric component technical field, is specifically related to electric connector.
Background technology
Electric connector is mainly applied in device and device, assembly and assembly, carries out between system and system being electrically connected and signal transmission, is formation necessary base components of completion system.And hermetically-sealed electrical connector, generally have in the environment of higher requirement in the sealing of connector to use, can be widely used in the circuit breaker in mesohigh power transmission and distribution industry, GIS, all kinds of pressure tool instrument, wiper seal transducer, SF6 air density meter and the high-tension apparatus of relevant SF6 air seal, all kinds of vacuum equipment, with in the various kinds of equipment of closed container.Along with the environment for use of connector is further harsh, the requirement of user to hermetic seal connector properties of product also improves thereupon, needs it can stand larger pressure.
At present, the most frequently used cylindrical hermetically-sealed electrical connector generally comprises housing, insulating base and contact pin.There is the problems such as resistance toly force down, poor air-tightness, thermal adaptability are poor, intensity is low in a lot of cylindrical hermetically-sealed electrical connector.
Therefore, how to improve the resistance to pressure of cylindrical hermetically-sealed electrical connector, air-tightness, thermal adaptability, pull resistance be the problem that those skilled in the art need to think deeply.
Utility model content
Main purpose of the present utility model is to provide that a kind of resistance to pressure is good, air-tightness is stablized, tensile strength large and the cylindrical hermetically-sealed electrical connector that thermal adaptability is strong.
For reaching above object, the technical solution adopted in the utility model is: a kind of cylindrical hermetically-sealed electrical connector, comprise housing, insulating base and contact pin, it is characterized in that: described insulating base is glass insulation seat, described housing is metal shell, described glass insulation seat sealing by fusing is fixed in described metal shell, and described contact pin passes described glass insulation seat when described glass insulation seat molten condition, and is fixed in described glass insulation seat.After using metal shell and glass insulation seat, every electric property and sealing property are more than ten times of original plastic casing connector, and solving original plastic casing connector installs loaded down with trivial details, the easy shortcoming such as aging in adverse circumstances, reaches that resistance to pressure is good, air-tightness is stablized, tensile strength large and the object that thermal adaptability is strong.
As preferably, described metal shell adopts mild steel, stainless steel or the manufacture of teleoseal material to form, and described contact pin adopts teleoseal or iron-nickel alloy manufacture to form.The scheme of above-mentioned different materials comparative optimization, but also do not get rid of use other materials.
As improvement, described contact pin outer surface plating has nickel dam or layer gold.Improve its solderability and circuit turn-on.
As improvement on the other hand, be provided with threaded joints inside described metal shell one end, described metal shell other end arranged outside has Access Division.Facilitate the connection of electrical connector assembly.
As preferably, described contact pin is 1 to 150 pieces.Different contact pin quantity should on different electric connectors.
Compared with prior art, the utility model has the advantage of: after using metal shell and glass insulation seat, every electric property and sealing property are more than ten times of original plastic casing connector, and solving original plastic casing connector installs loaded down with trivial details, the easy shortcoming such as aging in adverse circumstances, reaches that resistance to pressure is good, air-tightness is stablized, tensile strength large and the object that thermal adaptability is strong.
