Abstract
The utility model introduces a ladder type printed circuit board which is characterized in that the ladder type printed circuit board comprises a main printed circuit board, a transfer printed board, countersunk head screws, and nuts, wherein the main printed circuit board is provided with a hollow part for containing a device, a pad needed by signal connection, metal through holes needed by the fixation of the main printed circuit board and the transfer printed board, and device signal wires, the transfer printed board is provided with installation positions of devices to satisfy a pad needed by device welding, metal sink holes needed by the fixation of the main printed circuit board and the transfer printed board, a pad needed by signal connection and device signal wires, the countersunk head screws pass through the transfer printed board and the main printed circuit board, and the countersunk head screws are fixed at the component surface of the main printed circuit by the nuts. According to the ladder type printed circuit board, a new device installation method is provided, the height of the device can be lowered, the space is reasonably used, and the range of application is wide.
Description
Technical field
The utility model relates to a kind of about how utilizing limited space to reduce the technology, particularly a kind of staged printed board of the height of device.
Background technology
In research and development, production process, often there is the height-limited problem of device, if adopt lower device, on cost or in performance, may not there is good selection.Therefore need to take a kind of process, make under existence conditions, use the device in original ripe principle, reach lower dimensional requirement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of mounting means of device---and staged printed board, can make full use of limited space and reduce the height of product, and require fixing, firm welding.
The utility model has been introduced a kind of staged printed board, it is characterized in that: comprise main body printed board, switching printed board, sunk screw, nut;
Wherein, part, the signal that the hollow out of a containment device is set in main body printed board connects metal throuth hole, the device signal cabling of needed pad, stationary body printed board and keyset needs;
The installation site that is provided with device in switching printed board can meet the pad of device welding needs, stationary body printed board and metal counterbore, the signal of switching printed board plate needs and be connected needed pad, device signal cabling;
Sunk screw is through switching printed board and main body printed board, and nut is fixed on sunk screw the component side of main body printed board.
More specifically, staged printed board also comprises plain cushion, bullet pad, and plain cushion, bullet pad attaching nut are fixed on sunk screw the component side of main body printed board.
The printed board of transferring when connection need to weld the device that needs switching, switching printed board plate is placed in to the solder side of main body printed board, the pad of main body printed board, switching printed board is welded by scolding tin, sunk screw penetrates main body printed board from switching printed board, fixes at flat, bullet pad, the nut for component side of main body printed board.
Keyset is responsible for installing device, and is responsible for the signal of device connection in keyset to be delivered in main body printed board by pad, and the pad of upper and lower two-ply welds by scolding tin, and scolding tin will fully soak two welding holes.Two plates are worked in coordination and are fixed two printed boards by sunk screw simultaneously, on mainboard, fix with nut.
By adopting technique scheme, the utility model has reduced the height 1.5mm of device, has rationally utilized limited space.

Embodiment
Below in conjunction with accompanying drawing, this patent is further explained.But the protection range of this patent is not limited to concrete execution mode, also comprise that other device adopts identical method to reach the execution mode of same object.
Execution mode is shown in that Fig. 1 is to shown in Fig. 4.
The staged printed board of this patent, comprises main body printed board 2, switching printed board 5, sunk screw 9, plain cushion, bullet pad, nut; Part 1, signal that the hollow out of a containment device is set in main body printed board 2 connect the metal throuth hole 4 of needed pad 3, stationary body printed board 2 and keyset needs; The installation site that is provided with device in switching printed board 5 can meet the pad 6 of device welding needs, stationary body printed board 2 and metal counterbore, the signal of switching printed board 5 plate needs and be connected needed pad 3; Sunk screw 9 is through switching printed board 5 and main body printed board 2, and plain cushion, bullet pad attaching nut are fixed on sunk screw 9 component side of main body printed board 2.
The printed board 5 of transferring when connection need to weld the device that needs switching, switching printed board 5 plates are placed in to the solder side of main body printed board 2, the pad of main body printed board 2, switching printed board 5 is welded by scolding tin, sunk screw 9 penetrates main body printed board 2 from switching printed board 5, fixes at flat, bullet pad, the nut for component side of main body printed board 2.
Keyset is responsible for installing device, and is responsible for the signal of device connection in keyset to be delivered in main body printed board 2 by pad, and the pad of upper and lower two-ply welds by scolding tin, and scolding tin will fully soak two welding holes.Two plates are worked in coordination and are fixed two printed boards by sunk screw 9 simultaneously, on mainboard, fix with nut.
The condenser welding of a CD294 series can be received on keyset, a pad is set on mainboard and keyset simultaneously, and by this electric capacity, the connection track in circuit couples together.Can break counterbore fixed transfer plate to mainboard in surrounding, form staged printed board, reduce the high height of 1.5mm.
