Self sealing can be completed, achieved the purpose that simplified sealing structure, facilitated Operation and Maintenance.
Self sealing is realized using bound cell front end rectangular flange, has been taken into account while guaranteeing leakproofness easy to maintenance
Property, but also bring the positioning of forward end seal face and reliably dock conflicting technology with rear portion I/O electrical connector plug/socket and ask
The design of topic, i.e. structure should guarantee that I/O electrical connector plug (being located on bound cell) and socket (being located in installation base body) are right
Length requirement is plugged together when connecing, guarantees reliable contacts and the sealing in subrack unit rectangular flange face and matrix mounting surface again.For
This, is solved using following technological means: being set front end and is engaged that (the bound cell front end rectangular flange back side and installation base body are pacified in face
Dress face) and back contacts mating surface (the grafting positioning surface of socket in electrical connector plug and installation base body on bound cell) between
Distance is L, and the permission variation of inserting depth is that (data can be by electric connector type selecting hand by A between electrical connector plug and socket
Volume checks in, and is one of electric connector basic parameter), then a kind of feasible Dimension Chain Tolerance allocation plan is end moment before bound cell
The shape flange back side to the rear part I/O electrical connector plug grafting positioning surface is dimensioned toBefore installation base body mounting surface to its
Internal I/O electric connector socket grafting positioning surface is dimensioned toIt is used above-mentioned two size as closed-loop (design input)
It, can be complete while guaranteeing sealing requirements in bound cell and the respective inside dimension chain design of installation base body and calculating
The precise positioning of pairs of electrical connector plug and socket.
Bound cell according to the present invention uses modular construction, can be used alone, can also use in groups, has structure
It is compact, it is flexible in application, it is widely applicable the advantages that, with may make up resistance to environment, highly reliable one after installation base body Butt Assembling
Body electronics box structure, simplifies box body sealing structure, realizes being rapidly assembled and disassembled for bound cell, can be applied to can
In all kinds of modularized combination type electronic equipments that property, maintainability have higher requirements.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
