Abstract
The utility model relates to a vacuum electric connector with high reliability and long service life, which comprises wiring terminals and an insulation ceramic base board. The utility model is characterized in that the insulation ceramic base board is provided with a through hole through which the wiring terminals can pass; a layer of metal pulp is coated at the periphery of the through hole; the wiring terminals, the metal pulp and the insulation ceramic base board are sintered together; a layer of metal pulp is also coated at the periphery of the insulation ceramic base board; the metal pulp and the insulation ceramic base board are sintered together.
Description
Technical field
The utility model relates to a kind of Vacuum connector, particularly a kind of vacuum electrical connector.
Background technology
Fig. 1 is in order to the connection diagram of connection container intracavity with the electrical connector in the external world in the existing vacuum heat-insulation container, Vacuum connector is made of binding post 32 and ceramic insulating substrate 31, wherein binding post is installed on the insulating ceramics by nut 52, accompany rubber seal 42 between binding post and nut, insulating ceramics is installed in chamber wall with screw 51, accompanies rubber seal 41 between insulating ceramics and chamber wall; Sealing ring in this vacuum electrical connector is easily aging, thus its shortcoming be the life-span short, reliability is low.
Summary of the invention
The purpose of this utility model is the problem that life-span is short, reliability is low that exists in the existing vacuum electrical connector in order to solve, and a kind of reliability height, long vacuum electrical connector of life-span are provided.
Technical scheme:
The purpose of this utility model is achieved in that a kind of vacuum electrical connector, comprise binding post and ceramic insulating substrate, it is characterized in that having on the ceramic insulating substrate through hole that can allow binding post pass through, scribble the layer of metal slurry on this bore periphery, binding post, metal slurry are in the same place with the ceramic insulating substrate sintering; The ceramic insulating substrate periphery also scribbles the layer of metal slurry, and this metal slurry makes the outward flange of ceramic substrate form the layer of metal edge with the ceramic insulating substrate sintering together.During use with the metallization edge soldering on vacuum tank and the substrate periphery together, thereby the vacuum tank inner chamber is hedged off from the outer world.
Beneficial effect:
Owing to adopted technical scheme described in the utility model, metal on binding post and ceramic substrate slurry sintering has sealing function after together, and sealing function is arranged also after metallization edge on the ceramic substrate and the soldering of vacuum metal chamber wall, thereby need not to use rubber seal, there is not the aging problem of rubber seal, so vacuum electrical connector reliability height described in the utility model, life-span are long.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the use schematic diagram of existing vacuum electrical connector.
Fig. 2 is that vacuum electrical connector described in the utility model uses the structural representation when the vacuum electric heating case.
Fig. 3 is a vacuum electrical connector described in the utility model structural representation when using on the vacuum heat-insulation case.

Embodiment:
Embodiment one, and Fig. 2 vacuum electrical connector described in the utility model uses the structural representation when the vacuum electric heating case.As can be seen from Fig. 2, the vacuum electric heating case is made of casing 11 and lid 12, is provided with vacuum chamber 111 in the wall of casing 11, wherein has side opening on the outer wall, and the vacuum electrical connector stretches in the vacuum chamber 111 by this side opening; The vacuum electrical connector comprises binding post 2 and ceramic insulating substrate 1, have the through hole that can allow binding post 2 pass through on the ceramic insulating substrate 1, scribble on this bore periphery layer of metal slurry 201 and with ceramic substrate 1 sintering together, the cylinder of binding post 2 and metal are starched 201 sintering together; Ceramic insulating substrate 1 periphery also scribbles one deck and substrate 1 sintering metal slurry 101 together makes the ceramic substrate outward flange form the firm metallization edge of one deck, and the metal on the outer wall of vacuum chamber and substrate 1 periphery is starched 101 solderings together.Binding post stretches in the vacuum chamber and is electrically connected with electric heating body 3.The sintered combination of low-expansion binding post, metal slurry, ceramic substrate is in order to satisfy the feasibility and the reliability of high vacuum encapsulation and high temperature resistant electrical connection; This vacuum electrical connector can be used as high vacuum and is electrically connected encapsulation, or makes high temperature resistant, conventional high performance and long service life connecting structure for electrical equipment spare.
Embodiment two, and Fig. 3 is a vacuum electrical connector described in the utility model structural representation when using on the vacuum heat-insulation case.This vacuum heat-insulation case also can be popular at present vacuum heat-insulation electric cooker pot body.Wherein the structure of the vacuum electrical connector in the present embodiment and embodiment's one is identical, so, be not going to repeat.
