The technical scheme that its technical problem that solves embodiment of the present utility model adopts is: construct a kind of circuit board, described circuit board is provided with the connector that is connected with other circuit board, be provided with the reinforcement securing member of rigid material on the circuit board near described connector position, the shape and the size of the shape of described reinforcement securing member, size and connector are complementary.
In circuit board described in the utility model, described reinforcement securing member be arranged on the circuit board at the connector back side and the shape of described reinforcement securing member outline identical with the shape of connector cross section.
In circuit board described in the utility model, described reinforcement securing member is fixed in the height of described circuit board all elements greater than back of circuit board.
In circuit board described in the utility model, described reinforcement securing member is arranged on the circuit board of connector identical faces and described reinforcement securing member is a ring-type and around described connector setting, the shape of shape of ring and size and connector cross section and big or small identical in it.
In circuit board described in the utility model, described reinforcement securing member is parallel to the length direction setting of connector.
In circuit board described in the utility model, be provided with location hole near the connector installation site of described circuit board, described reinforcement securing member is provided with installing hole, and described reinforcement securing member arrives circuit board by screw, rivet or the snap fit of passing positioning holes on circuit board and reinforcement securing member installing hole.
In circuit board described in the utility model, described reinforcement securing member is fixed in circuit board with gluing or snap fit.
In circuit board described in the utility model, described reinforcement securing member is ring dress or strip.
The circuit board of embodiment of the present utility model, by the reinforcement securing member is set, part has been born the stress that causes the circuit board distortion, has reduced the distortion of circuit board in installation and demolishing process, thereby has avoided being come off by component wear and solder joint that the circuit board distortion causes.Embodiment of the present utility model also strengthens the height of securing member by increase, but the feasible crashproof muscle of securing member double as of strengthening.

Embodiment
As shown in Figure 5, be to realize the function expansion, first circuit board 51 is plugged into second connector 54 on the second circuit board 52 by first connector 53 on it, thereby realizes being connected of first circuit board 51 and second circuit board 52.Wherein first connector 53 and second connector, 54 composition connectors are right, realize being connected of first circuit board 51 and second circuit board 52 internal circuits.
For reducing to insert second connector 54 at first connector 53, or when extracting, cause by second connector 54 circuit board section that is attached thereto to be out of shape (may cause this crushed element component wear or solder joint to break away from), in the present embodiment, at the back side of second connector 54 of second circuit board 52 and first connector, 53 back sides of first circuit board 51 be fixed with respectively and strengthen securing member 55.This reinforcement securing member 55 is made by rigid material, can disperse this stress when its standing part circuit board is subjected to stress, reduces the deformation of circuit board, thereby surface mount elements body and solder joint are stressed less around making, are difficult for losing efficacy.
In the present embodiment, strengthening the size of securing member 55 and the size and the shape of shape and connector 53,54 is complementary, promptly when reinforcement securing member 55 is located at the back side of connector 53,54, this shape of strengthening securing member 55 outlines is identical with the shape of cross section of connector 53,54, and size equals or be slightly larger than the size of connector 53,53.When reinforcement securing member 55 was installed, its installation direction was parallel to the length direction of connector 53,54.Certainly, in actual applications, size and the shape of strengthening securing member 55 also can require to change according to varying strength, and generally speaking, the size of strengthening securing member 55 is big more, and intensity is big more.
The shape of strengthening securing member 55 can be the different shape suitable mutually with the connector shape, and avoiding the too much elements on circuit board layout that influences, it can be for such as (shown in the reinforcement securing members among Fig. 6-9 60,70,80,90) such as chip, bar formula, ring types.
Strengthen the material of securing member 55, generally adopt metal material, can obtain higher intensity, ifs circuit plate wiring area anxiety also can be selected nonmetal parts for use, to reduce the influence to wiring.
When mounted, strengthen securing member 55 and can use screw, riveted joint, gluing connecing or mode such as clamping with the connection of circuit board.Location hole for example can be set near the connector of circuit board and installing hole be set at reinforcement securing member 55 two ends, make reinforcement securing member 55 be close to back of circuit board by screw, rivet or the buckle that passes above-mentioned location hole and installing hole and also keep stable, thereby make its stress that when circuit board is out of shape, bears circuit board, reduce the circuit board distortion.
In the present embodiment, strengthen the every other element of the height of securing member 55, strengthen the metamorphosis that securing member 55 removes near the circuit board of connector when being used to reduce circuit board assembling, dismounting, can also use by the crashproof muscle of double as thereby make a little more than back of circuit board.
In another embodiment of the present utility model, strengthen securing member 55 and be arranged at the same side of connector, and make reinforcement securing member 55 around connector, when being out of shape, bears by circuit board the stress of circuit board equally, reduce the circuit board distortion.At this moment, the shape and the size of reinforcement securing member 55 are also mated with connector.In the present embodiment, strengthening securing member 55 be that the shape of ring-type and interior ring is identical, big or small identical with the shape of cross section of connector 53,54.
Certainly, the reinforcement securing member 55 in the foregoing description removes and is applied to veneer connector, also can be applicable to the connector of other types, for example promptly plugs in the connector of type element etc.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
