Abstract
The utility model relates to a sealed connector which comprises the components of: an aluminum housing, a low-temperature glass flake, a first ceramic sheet, a copper alloy contactor and a second ceramic sheet. The copper alloy contactor is provided with the low-temperature glass flake. Two sides of the low-temperature glass flake are respectively provided with the first ceramic sheet and the second ceramic sheet. The copper alloy contactor is arranged in the aluminum housing. The aluminum housing and the copper alloy contactor are sealed together. According to the sealed connector provided by the utility model, the aluminum housing and the copper alloy contactor are adopted for performing hermetical jointing on the glass, and the mass of the connector is greatly reduced. Furthermore the leakage rate does not exceed 1*10<-3> Pa*cm<3>. The sealed connector has the advantages of: simple structure, stable technical index, effective satisfaction for actual use, and high application effect.
Description
Technical field
The utility model relates to a kind of electric connector, and especially a kind of hermetically sealed connector, belongs to technical field of electric connectors.
Background technology
In prior art, in hermetically sealed connector field, the best connector of sealing property is to adopt kovar alloy or stainless steel to make housing, with the contact arranging in housing endoporus by together with glass sealing, this sealing technology need to be at high temperature by glass melting, and sealing temperature is very high.This class connector is because the density ratio of material is larger, and this has just caused the quality of connector larger, cannot realize the lighting of connector.
Utility model content
The deficiency that the utility model exists for prior art just, provides a kind of hermetically sealed connector.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of hermetically sealed connector, comprise: aluminium shell, low temperature glass sheet, the first potsherd, copper alloy contact and the second potsherd, low temperature glass sheet is housed on copper alloy contact, in the both sides of low temperature glass sheet, the first potsherd and the second potsherd are installed respectively, copper alloy contact is arranged in aluminium shell, and aluminium shell is together with the glass sealing of copper alloy contact.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
Hermetically sealed connector described in the utility model, it adopts aluminium shell and copper alloy contact to carry out glass sealing, and connector quality reduces greatly, and its leak rate is not more than 1 * 10
-3pacm
3.It is simple in structure, and technical indicator is stable, meets actual operation requirements, and implementation result is good.
Accompanying drawing explanation
Fig. 1 is hermetically sealed connector front view described in the utility model;
Fig. 2 is the vertical view in Fig. 1;
Fig. 3 is the left view in Fig. 1.
Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Fig. 1 ~ Fig. 3, hermetically sealed connector described in the utility model, comprising: aluminium shell 1, low temperature glass sheet 2, the first potsherd 3, copper alloy contact 4 and the second potsherd 5.The conductive contact piece that copper alloy contact 4 is electric connector, low temperature glass sheet 2 is housed on copper alloy contact 4, the first potsherd 3 and the second potsherd 5 are installed respectively in the both sides of low temperature glass sheet 2, copper alloy contact 4 is arranged in aluminium shell 1, glass dust by the first potsherd 3 and the second potsherd 5 melts, aluminium shell 1 and copper alloy contact 4 are sealed, form hermetically sealed connector.
In order to guarantee sealing property, the housing of connector and sealed compartment need to be welded together, between different materials, firm welding degree is poor, and sealing is not easy to guarantee.Aluminium shell 1 of the present invention, adopts aluminum alloy material to do shell, can be directly and sealed compartment melting welding weld, connector sealed compartment is welded together, improve its reliability.
In addition, aluminium body seal connector is compared with kovar alloy shell or stainless steel casing hermetically sealed connector, its weight will subtract light, the density of aluminium alloy is only steel alloy 0.36, the density of copper alloy is 1.15 times of steel alloy, comprehensively get off, aluminium body seal connector is than gently at least 2.5 times of original hermetically sealed connectors.
