Abstract
The utility model provides a high pressure resistant sealed electric connector, this electric connector includes shell, contact, base, glass sealing layer and encapsulating fixed bed, is connected through the glass sealing layer between contact and the shell, and the glass sealing layer is equipped with boss glass sealing layer butt joint terminal surface mounting base, is connected through embedment rigid glue between base and the shell. The utility model has simple structure, applicability and reliability; the volume is small, and the miniaturization requirement is met; high sealing performance index and high pressure resistance.
Description
Technical field
The utility model relates to a kind of high pressure resistant sealed electrical connector, belongs to technical field of electric connectors.
Background technology
Along with the develop rapidly of aeronautical and space technology, each machine system has proposed various property requirements to institute's use electric connector, not only requires connector to have the sealing effectiveness of low leak rate, reaches 1 * 10
-3Pa.cm
3/ s, and require connector to have high pressure resistant function, reach more than the 6000V.Sealing property requirement for connector, can adopt setting-in structure, embedding fluid sealant structure, elastic rubber structure or glass capsulation structure etc. generally speaking, be subjected to the restriction of technology and material horizontal, setting-in structure, embedding fluid sealant structure and elastic rubber structure can't satisfy leak rate 1 * 10 at present
-3Pa.cm
3Therefore the index request of/s, under the requirement of low leak rate index, generally adopts the glass capsulation structure.Yet, all can realize sealing-in in order to make glass and connector shell and contact, the selection of glass material is subjected to certain limitation.Under the less situation of connector overall dimension, the glass material dielectric constant of sealing-in of realizing commonly used can not satisfy the requirement of the withstand voltage index of product 6000V.
The utility model content
Technical problem to be solved in the utility model is to increase the electric connector creepage distance, satisfies its glass sealing process requirement simultaneously, and a kind of high pressure resistant sealed electrical connector structure is provided for this reason.
The high pressure resistant sealed electrical connector of the utility model comprises: shell, contact, pedestal, glass seal layer and encapsulating fixed bed, be connected by glass seal layer between contact and the shell, glass seal layer is provided with boss, glass seal layer butt joint end face is installed described pedestal, is connected by the encapsulating fixed bed between pedestal and the shell.
Described encapsulating fixed bed is a rigidity glue.
Adopt the beneficial effects of the utility model of said structure scheme to have:
1, simple in structure, suitable, reliable;
2, volume is little, satisfies the miniaturization requirement;
3, sealing property index height, high pressure resistant.
Description of drawings
Fig. 1 is a kind of high pressure resistant sealed electrical connector structural representation of the utility model.
Among the figure: 1-shell, 2-encapsulating fixed bed, 3-pedestal, 4-contact, 5-glass seal layer, 5a-glass boss, 5b-glass boss.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 shows the high pressure resistant sealed electrical connector structure of the utility model.This electric connector comprises shell, contact, pedestal, glass seal layer and encapsulating fixed bed, shell 1 profile is a rectangle, have two installing holes on its ring flange, inner chamber adopts Milling Process, be connected by glass seal layer 5 between contact 4 and the shell 1, its connection is to adopt glass sintering technology to carry out, glass seal layer can guarantee that connector leak rate index meets the demands, glass seal layer is provided with boss 5a and 5b, boss 5a and boss 5b size require to be provided with according to creepage distance, at glass seal layer 5 butt joint end faces described pedestal 3 is installed, to improve between the connector contact, creepage distance between contact and the shell satisfies the high pressure resistant requirement of product; Pedestal 3 is connected with embedding rigidity glue between the shell 1, has the groove of annular on shell 1, forms encapsulating fixed bed 2 after the adhesive curing of embedding rigidity, to guarantee that pedestal 3 is connected reliably with shell 1.
