Abstract
The invention discloses a flexible printed circuit, wherein an arm part extended from a reinforcing board in the connecting end of the flexible printed circuit is adopted. When the flexible printed circuit is connected with a connector on the circuit board by the connecting end, the arm part of the reinforcing board will be located in another propping side opposite to the connecting side of the connector. Since the arm part is supported by the propping side, the flexible printed circuit will not fall off the connector. Therefore, the flexible printed circuit is effectively fixed.

[embodiment]
Please refer to Fig. 1, Fig. 1 is the sketch map of flexible circuit board one first embodiment that the present invention disclosed.Flexible circuit board 1 is connected between two elements/module; It has the body 11 of a circuit board; Body 11 extends upward to be connected on the element (schemes not show, for example the light source component of module backlight) that body 11 downward links 12 then have a plurality of contacts 14; A plurality of contacts 14 are used for and another element; For example a connector 100 (please refer to Fig. 2) of the control circuit board of module backlight connects, and the characteristic that flexible circuit board 1 flexible is bent, and it is little with the space between the element and need be connected the occasion of controlling with circuit to can be applicable to element.In first embodiment, flexible circuit board 1 has a stiffening plate 13 in addition at link 12, and it is the hard plastic plate, but stiffening plate 13 ease of assembly personnel grip so that flexible circuit board 1 is connected upward connector 100.Then extension has an arm 15 and a holes 16 on stiffening plate 13, and in this embodiment, arm 15 is the draw ring shape of annular; And be positioned at one of holes 16 side; 14 of a plurality of contacts of link 12 are positioned at holes 16, and in this embodiment, holes 16 is polygonal for sealing.When flexible circuit board 1 was connected in connector 100, connector 100 just can be positioned at holes 16.
Please refer to Fig. 2, it is installed on the sketch map of connector 100 for flexible circuit board 1.Flexible circuit board 1 is along L
1Direction is installed on connector 100, and a plurality of electronic contacts 111 that make a plurality of contacts 14 of link 12 be connected side 110 with one of connector 100 electrically connect respectively.Flexible circuit board 1 is being installed in the process of connector 100, at first can be earlier along D direction (or vertical L
1Installation direction) arm 15 of pulling stiffening plate 13 makes it upwards to produce flexible flexural deformation, then along L
1Direction is inserted contact 14 the connection side 110 of connector 100; Can decontrol this moment and originally upwards pull the arm 15 of distortion; Its elasticity makes arm 15 reply original external form, and moves in against side 120 with from top to bottom mode, and makes connector 100 be positioned at holes 16.After flexible circuit board 1 was installed on connector 100, connector 100 was along L
1Direction connects the opposite side (against side 120) of side 110 relatively, just can prop up the arm 15 of stiffening plate 13, therefore against side 120 along L
1Direction is only supported and is limited arm 15 and move to avoid flexible circuit board 1 to get loose; Simultaneously the piano lid element 130 on connector 100 covers the fixedly terminal 14 of flexible circuit board 1, so can effectively be fixed on flexible circuit board 1 on the connector 100 and a plurality of contacts 14 of link 12 are electrically conducted with completion with a plurality of electronic contacts that are connected side 110 111 certain contacts of connector 100.In the present embodiment, body 11 is along L
1Rightabout extension is pullled (for example along L when flexible circuit board 1 receives external force
1Rightabout external force) time,, therefore can not pull to cause flexible circuit board 1 to come off from connector 100 because of external force owing to arm 15 quilts are propped up against side 120.In addition, the loop configuration of the arm 15 among first embodiment also plays a part to surround fixing in the two sides 140,150 of connector 100, and the link 12 that can effectively limit flexible circuit board 1 is all directions moving relative to connector 100.
Among first embodiment except Fig. 1, in remaining diagram of the present invention, then disclosed the sketch map of other embodiment of flexible circuit board.For example in second embodiment of Fig. 3, the body 21 of flexible circuit board 2 is to L
1Direction is extended, and is installed on the installation direction L of connector 100 with contact 24
1Equidirectional, and when flexible circuit board 2 was installed on connector 100, the arm 25 on the stiffening plate 23 was supported by connector 100, make the end points 24 can be along L
1Direction comes off.
In the embodiment of Fig. 4 and Fig. 5,31,41 of the bodies of flexible circuit board 3,4 are respectively along L
2And L
3Direction is extended, and in these embodiment, L
2And L
3Direction is all perpendicular to L
1Installation direction.Therefore at the contact 34,44 of flexible circuit board 3,4 along L
1When direction was connected in connector 100, the arm 35,45 of stiffening plate 33,43 can receive ending to making flexible circuit board 3,4 can not come off from connector 100 of connector 100 respectively.
Except as aforementioned four embodiment in, the arm of flexible circuit board be the draw ring form of annular, and outside the example of centre formation holes, in the embodiment of Fig. 6 to Fig. 8, also can use the arm of L type or inverted L shape.For example in the 5th embodiment of Fig. 6, the arm 55 of flexible circuit board 5 presents inverted L shape, and the section of its level can only be supported by connector and produce effectively fixing effect.In the 6th embodiment of Fig. 7, the arm 65 of flexible circuit board 6 presents positive L type, and the section of its level can only be supported by connector and produce effectively fixing effect.In the 7th embodiment of Fig. 8, have a hole 76 (or gap) between the arm 75 of flexible circuit board 7, and make two arms 75 be respectively L type and inverted L shape, two arms 75 surround about oneself respectively and extend, and also can produce same effect.The external form of the described arm of aforementioned each embodiment is merely the part preferred embodiment that the present invention discloses; But not as limit, all designs that in the stiffening plate of flexible circuit board, has arm end for connector to be supported in case the design that anti-avulsion falls all should be in the scope that the present invention disclosed.
Utilize the arm that stiffening plate extended out of the link of flexible circuit board; When flexible circuit board is connected in a connector on the circuit board with link; The arm of stiffening plate can be positioned at that connector connects side relatively another against side; Because of receiving against only the supporting of side, flexible circuit board can't be come off from connector, reach effectively fixing purpose.
The above is merely the present invention's preferred embodiment, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to the present invention's covering scope.
