Description
Technical field
The present invention relates to printed board and structure-design technique field, more particularly to a kind of printing electricity based on modular construction
Road plate and corresponding motherboard installation method.
Background technology
At present, aerospace electron unit uses Modular Structure Design more, modular construction for every group of printed circuit board or
The corresponding independent frame-type internal structure of person's circuit function module design, the external structure of each framework is essentially identical, this to set
Meter mode is easy to the design of individual module, and the rigidity of structure is stronger, there is good scalability.
Different from structure-integrated design, the transmission that modular structure design must solve signal between each functional module is asked
Topic, not only to ensure the reliability of signal connection, also to take into full account it to electronics unit integral layout and the shadow of Weight control
Ring.Used in the electronics unit of modular structure design is at most following two signals transmission：
1st, inside cable connected mode.In the connected mode, welding lead is utilized between each functional module internal connector
Electrical connection is formed, and is fixed by conducting wire binding and epoxy resin, forms electronics unit inside cable.Which simply may be used
Lean on, but inside cable weight is larger, and the volume taken is larger, adds the volume and weight of total part, does not meet
Aerospace electron unit product high density, light-weighted development trend now；
2nd, motherboard connected mode.In the connected mode, connector body is mounted with motherboard, its connecting contact pin is by circular
Through hole is welded on motherboard, the electrical connection formed using printed circuit between each electric connector.Which is with printed board cabling
The connection between signal is realized instead of wire, makes total part weight saving, is that the preferred of electronics unit internal signal connection connects
Connect mode.
Motherboard connected mode has the characteristics that and technical requirements：1st, internal connection signal is more, needs to fill on usual motherboard
Carry a large amount of connector bodies so that motherboard plate face size is larger；2nd, on motherboard connector body typically by pressure insert directly with
Motherboard is connected, and requires very strict to socket aperture；3rd, because aerospace electron unit functional module is more, chi after modules assembling
Very little cumulative limit is larger, therefore requires very high to modular structure part machining tolerance；4th, aerospace electron unit is usually required by shaking
The strict environmental tests such as dynamic, impact, overload are very high to motherboard reliability requirement.
Therefore, usually because motherboard aperture and functional module nominal clearances are accumulated in practical operation, it is difficult to ensure motherboard
Connector and functional module internal connector are smoothly docked, or even connector pinout is bent now by stress in docking operation
As carrying out vibration test in this case will make internal connector pin come off or be broken, and have a strong impact on quality of space product.
The content of the invention
It is an object of the invention to provide a kind of printed circuit board based on modular construction and corresponding motherboard installation side
Method, the connector body through hole on printed circuit board and corresponding pad design are track type by it, laterally long by increasing it
Spend to offset the cumulative limit in motherboard aperture and functional module size；A kind of corresponding motherboard installation method is also proposed simultaneously,
The smooth docking of connector body and functional module internal connector is ensure that, avoids damage.
In order to achieve the above object, the present invention is achieved through the following technical solutions：

Big 5 ~ the 20mil in footpath.
A kind of motherboard installation method, it is characterized in that, comprise the following steps：
S1, by connector body prepackage on a printed circuit board；
S2, the relevant position that the printed circuit board being pre-installed is positioned over to functional module；
S3, with the track type through hole on printed circuit board, the position of connector is finely adjusted, make connector body and
A pair of functional module internal connector plug 1 is inserted；
S4, will installation fastener be connected with motherboard；
S5, by connector pinout it is corresponding with the pad on printed circuit board welding, complete motherboard electrical connection.
Above-mentioned motherboard installation method, wherein, described step S4 is specifically included：
S51, will installation fastener be positioned in motherboard mechanical mounting hole, connector position is finely adjusted again, makes mother
Plate installation fastener can be fastened effectively；
S52, complete motherboard mechanical erection.
The present invention has advantages below compared with prior art：
1st, the present invention abandons traditional manhole and circular pad structure, and connector body installation through-hole is designed as
Shape is gone to, so adds the lateral length of through hole to offset the cumulative limit in motherboard aperture and functional module size, and it is longitudinal
Length is constant, ensure that the fastness of connector welding；
2nd, motherboard installation method proposed by the invention, it not only ensure that connector and the smooth of functional module are kept away inserting
The stress damage of connector is exempted from, has also reduced electronics unit weight, there is good engineering application value.
