Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Present embodiment improves the versatility of flexible circuit board in order to prolong the useful life of flexible circuit board, is provided with two connectors 1,2 and golden finger pads 3 simultaneously on single flexible wiring board 4, referring to shown in Figure 3.One of them connector 1 is laid in an end of flexible circuit board 4, and the other end of flexible circuit board 4 is laid golden finger pad 3, lays second connector 2 between the two ends.On the PCB cabling, two connectors 1,2 are in parallel, identical with interface definition on the golden finger pad 3 then pin connects correspondingly, just can realize thus connector 1,2 and golden finger pad 3 between signal communication, formation can compatible connector-connector, the multifunction flexible wiring board of connector-two kinds of connected modes of golden finger pad, to improve the single flexible wiring board to the tested printed board of different interface type and the compatible concatenation ability of test component, make the versatility of flexible circuit board more extensive.
Specifically, when the interface type of tested printed board and test component all is connector, can utilize on the multifunction flexible wiring board two connectors 1,2 respectively with tested printed board on connector and the corresponding grafting one by one of the connector on the test component, to satisfy the request signal transmission between tested printed board and the test component.When the interface type of tested printed board and test component is the form of a connector, a golden finger, then can utilize connector 1 on the multifunction flexible wiring board or connector 2 and connector in the tested printed board (perhaps test component) to plug, utilize the golden finger pad 3 on the multifunction flexible wiring board to weld mutually with golden finger on the test component (perhaps tested printed board), to satisfy the request signal transmission between tested printed board and the test component.
Because connector has the branch of plug and socket, in order to improve the versatility of multifunction flexible wiring board, preferably adopts plug and socket as described two connectors 1,2, is laid on the described flexible circuit board 4.When the connector on tested printed board or the test component is plug, can utilize the socket 2 on the flexible circuit board 4 to be mated grafting; When the connector on tested printed board or the test component is socket, can utilize the plug 1 on the flexible circuit board to be mated grafting.Consider easily that for plug present embodiment preferably is laid in plug 1 end of flexible circuit board 4, and the plug direction of plug 1 preferably is parallel to the length direction of flexible circuit board 4; Socket 2 is laid in the middle part of flexible circuit board 4, and the socket direction of socket 2 is preferably perpendicular to the length direction of flexible circuit board 4, to make things convenient for tester's wiring operation.
Consider the tested printed board and the test component that adopt the connector inserting mode to carry out the signal transmission, the type of its connector is normally adaptive, namely select supporting plug and socket usually for use, thereby in order to satisfy this connection request of connector-connector, the plug 1 that is arranged on the described multifunction flexible wiring board is also preferably selected the suitable set of connectors that becomes with socket 2, to simplify the wiring operation.
Adopt the multifunction flexible wiring board of present embodiment, when the connector 1 that is positioned at flexible circuit board 4 ends is damaged, can crop with that part of flexible circuit board 4 of instruments such as cutting nippers, scissors with this connector 1 place, only stay connector 2 from middle position to one section flexible circuit board 4 the golden finger pad 3, as shown in Figure 4, this section flexible circuit board 4 can directly be used, and satisfies the request signal transmission of connector-golden finger pad; After also can pegging graft with other flexible circuit board, be combined together use.
When the golden finger pad 3 that is positioned at flexible circuit board 4 ends is damaged, that part of flexible circuit board 4 at golden finger pad 3 places can be cropped, only stay one section flexible circuit board 4 between two connectors 1,2, as shown in Figure 5, this section flexible circuit board 4 can directly be used, satisfy the request signal transmission of connector-connector, after also can pegging graft with other flexible circuit board 4, be combined together use.For example: can with cutting shown in Figure 4 after flexible circuit board 4 link together and continue to use, as shown in Figure 6; Also can be plugged on an intact multifunction flexible wiring board 4 and be used, as shown in Figure 7.By different combinations, both prolonged the useful life of flexible circuit board, realize the support to the distinct interface type of attachment again, and then reached the compatible designing requirement of flexible circuit board.
A kind of preferred design as present embodiment, described socket 2 preferred cloth are located at the position of close golden finger pad 3 on the flexible circuit board 4, as shown in Figure 3, be distance between socket 2 and the golden finger pad 3 preferably less than the distance between socket 2 and the plug 1 continue to use so that flexible circuit board 4 is pegged graft separately or with other flexible circuit board after cutting.
In the present embodiment, two connectors 1,2 can be laid on the same one side of flexible circuit board 4, also can lay respectively on the branch two sides, for example plug 1 can be laid in the front of flexible circuit board 4, and socket 2 is laid in the back side of flexible circuit board 4.Connector 1,2 plugs for convenience, also the reverse side of preferably in flexible circuit board 4 position of plugs 1 and socket 2 being installed adds back-up block, to increase connector 1,2 intensity.
In the present embodiment, described back-up block can select for use designs such as steel plate or FR4 epoxy plate to realize, present embodiment is not limited in above giving an example.
Minimum feature and the distance between centers of tracks of the inside PCB cabling of described flexible circuit board 4 can be set to 0.1mm, wherein, power line and special power supply is arranged or the cabling of impedance requirement can be widened to 0.2mm, namely the width of the PCB cabling on the flexible circuit board 4 is preferably in value in the scope of 0.1mm ~ 0.2mm.If two connectors 1,2 are arranged on the same one side of flexible circuit board 4, and the profile width of flexible circuit board 4 is enough, and one deck flexible PCB 4 can only be set.But less in view of the space on the test fixture, and flexible circuit board 4 is generally narrow, therefore, preferably circuit is printed on more than or equal on 2 layers the flexible printed circuit, to make things convenient for the layout designs of flexible circuit board 4 inner cablings.
Certainly; the above only is a kind of preferred implementation of the present utility model, for those skilled in the art, and under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
