Abstract
The present invention relates to a board-to-board connection method for connecting at least two circuit boards, specially for connecting soft circuit board with rigid circuit board. It includes integrally-stamped pressing piece, positioning piece and soldering piece, the soldering piece is soldered on the rigid circuit board, the conductive terminals of two circuit boards are aligned and positioned by means of positioning piece, and the pressing piece is placed against the soft circuit board so as to make the correspondent conductive terminals on two circuit boards be further connected.
Description
[technical field]
The present invention relates to of the method for attachment of a kind of plate, relate in particular to the method for attachment of flexible circuit board and rigid circuit board plate.
[background technology]
In various portable electron devices, situation about two circuit boards need be connected usually appears, especially a flexible circuit board is connected with a rigid circuit board.To this, generally there is dual mode to connect.First kind of mode can be consulted United States Patent (USP) the 5th, 816, board to board connector shown in No. 845 and website: the ME-X-type series of products that disclose among the www.speurope.nl.The board to board connector of these prior aries generally is welded on the rigid circuit board, comprises insulating body, conducting terminal and actuator, by actuator flexible circuit board is retained in the board to board connector, and by conducting terminal two circuit boards is electrically connected.Yet these board to board connector assemblies are more, and manufacturing cost is higher, and need take bigger space, are unfavorable for that electronic product develops to miniaturization.
The board to board connector of the second way that industry adopts, as United States Patent (USP) the 6th, 045, shown in No. 396, the board to board connector of the prior art comprises rigidity clamping plate and a pair of screw that is located at rigidity clamping plate two ends, the termination contact portion of clamping two circuit boards makes them reach electric connection to the rigidity clamping plate by the fastening force of screw.Compared to first kind of mode, this board to board connector is simple in structure and cost is lower.Yet the rigidity clamping plate that this board to board connector adopted provide clamping power by the fastening of two ends screw, step complexity when the installation and removal flexible circuit board, and the existence of screw can't further reduce the height of this board to board connector.
[summary of the invention]
The object of the present invention is to provide that a kind of step is simple, cost is lower and can make things convenient for the method for attachment of the plate of disconnect circuit plate to plate.
Plate of the present invention is to the method for attachment of plate, be used for connecting at least two circuit boards, especially flexible circuit board and rigid circuit board, comprise that integrated punching goes out compressed tablets, spacer and bonding pad, weld part is welded on the rigid circuit board, by the conducting terminal positioned in alignment of spacer, make compressed tablets compress flexible circuit board, and then connect conducting terminal corresponding on two circuit boards two circuit boards.
Compared to prior art, plate of the present invention only uses a slice sheet metal to be stamped to form to the method for attachment of plate, and cost is lower, and volume is less, and only relies on the elastic force of sheet metal to connect two circuit boards, can make things convenient for the installation or removal flexible circuit board with compressed tablets is cocked.

[embodiment]
Please be simultaneously referring to figs. 1 through shown in Figure 4, plate of the present invention uses a board to board connector 10 that is formed by a slice sheet metal integrated punching to the method for attachment of plate, be used to connect flexible circuit board 20 and rigid circuit board 30, comprise bonding pad 11, compressed tablets 12, guidance part 13 and a pair of spacer 14.Bonding pad 11 is an arc spring lamination, and its rear section is approximate V-shaped.The rigid sheet of compressed tablets 12 for extending forward from bonding pad 11 forward edge.Spacer 14 bends extension downwards from the two ends of compressed tablets 12 respectively.Guidance part 13 is from the slightly upwards bending extension of forward edge of compressed tablets 12.
During assembling, earlier bonding pad 11 is weldingly fixed on the weld part 31 of rigid circuit board 30, at this moment, compressed tablets 12 and spacer 14 abut against the upper surface of rigid circuit board 30 under the effect of elastic force.Then, compressed tablets 12 is pulled from rigid circuit board 30, and the docking section 23 of flexible circuit board 20 is placed between compressed tablets 12 and the rigid circuit board 30, conducting terminal 22,23 is aligned.Unclamp compressed tablets 12, at this moment, spacer 14 passes corresponding location hole 21 and connects with banking stop 33, and compressed tablets compresses the upper surface of the docking section 23 of flexible circuit board 20, makes conducting terminal 22,32 reliably connect.By the effect that holds of spacer 21, can accurately locate the position of flexible circuit board 20, and prevent that flexible circuit board 20 from coming off.Along guidance part 13 that compressed tablets 12 is cocked, promptly dismountable flexible circuit board 20.Certainly, by adjusting the layout of circuit board, can use the present invention to reach connection between the polylith circuit board.
Claims (6)
