Referring to fig. 1-5, the present invention provides a clamping member, including:

a base plate 1;

the baffle 2 is arranged on the bottom plate 1, the baffle 2 is provided with a limiting block 3 and a supporting plate 4, and an installation groove 5 is formed between the limiting block 3 and the supporting plate 4;

the bottom plate 1 is provided with a buckle 6, and the support plate 4 is provided with a clamping hook 7 matched with the buckle 6.

It should be noted that the utility model discloses mainly used is to the assembly of printed circuit board, and bottom plate 1 is used for fixing on other structural component, and buckle 6 through on the bottom plate 1 and the trip 7 cooperation on backup pad 4 are fixed with backup pad 4, with printed circuit board assembly in stopper 3 and the mounting groove 5 that backup pad 4 formed can. This embodiment need not can accomplish printed circuit board's assembly through pressing printed circuit board, has convenient operation, dismouting simple, advantage that intensity of labour is little. Of course, the bottom plate 1 may be provided with the hook 7, the support plate 4 may be provided with the buckle 6, and the support plate 4 may be fixed in the same manner.

As an alternative to the above-mentioned embodiment, the bottom plate 1 is formed with a connecting groove 8, and the shutter 2 is mounted to the connecting groove 8, specifically, the shutter 2 is rotatably mounted to the connecting groove 8. The design is such that the baffle 2 can be turned inside out by a certain angle. When installing printed circuit board, can be earlier with baffle 2 outside certain angle that overturns, place printed circuit board in mounting groove 5, then with baffle 2 inside upset again for install 6 joint of buckle on backup pad 4 on the bottom plate 1 trip 7, realize printed circuit board's assembly. This embodiment realizes

trip

7 and 6 joint of buckle through the upset of baffle 2, compares in prior art and presses printed circuit board, and the dynamics that needs is littleer, and joint intensity also holds easily, can reduce operator's intensity of labour to can not cause the damage to printed circuit board.

Further, the joint spare is still including installing in locating plate 9 and the brace rod 10 of bottom plate 1, and the one end and the locating plate 9 of brace rod 10 are connected, and locating plate 9 sets up with baffle 2 relatively, still is provided with locating piece 11 on the locating plate 9, is formed with holding tank 12 between brace rod 10 and the locating piece 11. The locating piece 11 corresponds the setting with stopper 3, and the effect of brace rod 10 is similar with backup pad 4, all is used for supporting printed circuit board, and printed circuit board's both ends joint respectively is in mounting groove 5 and holding tank 12. During the assembly, can install printed circuit board's one end in holding tank 12 with baffle 2 outside certain angle of overturning earlier, the other end is installed in mounting groove 5, then with baffle 2 inside upset to backup pad 4

trip

7 and 6 joints of buckle, accomplished printed circuit board's assembly promptly. This embodiment supports printed circuit board through brace rod 10 and backup pad 4 respectively to fix printed circuit board from printed circuit board's both ends respectively through mounting groove 5 and holding tank 12, it is more steady firm to assemble.

Further, the height of the upper surface of the support rib 10 is the same as the height of the upper surface of the support plate 4. The upper surfaces of the support ribs 10 and the support plate 4 are the top surfaces of the support ribs and the support plate, so that the printed circuit board can be horizontally placed without deformation in the assembling process, and the printed circuit board is prevented from being damaged.

Further, the limiting block 3 is formed with a first guiding inclined surface 31, the first guiding inclined surface 31 is inclined downwards from the top end of the limiting block 3 towards the support plate 4, the positioning block 11 is formed with a second guiding inclined surface 111, and the second guiding inclined surface 111 is inclined downwards from the top end of the positioning block 11 towards the support rib 10. In the actual assembly process, the printed circuit board is put in from the upper side of the clamping piece, and those skilled in the art can understand that the printed circuit board has certain elasticity, and the first guiding inclined surface 31 is arranged on the limiting block 3 and the second guiding inclined surface 111 is arranged on the positioning block 11, which is mainly used for facilitating the putting in of the printed circuit board.

Further, the support rib 10 includes two side plates disposed at an interval, and a chamfer 101 is formed on one side of the two side plates facing the accommodating groove 12. Two curb plates support backup pad 4 from printed circuit board's both sides respectively, and two curb plates that the design set up relatively are not designing a whole supporting shoe, mainly in order to alleviate the weight of joint spare, also can save material simultaneously, reduce the cost of manufacture. The chamfers 101 are provided on the side plates mainly to prevent scratches on the printed circuit board during the putting in process of the printed circuit board and the inward rotation of the barrier 2. Of course, a chamfer could also be provided on the side of the support plate 4 facing the printed circuit board, again to reduce possible scratching of the printed circuit board.

Furthermore, the hook 7 is connected to the bottom surface of the support plate 4, a through hole matched with the buckle 6 is formed in the hook 7, and the thickness of the hook 7 is gradually reduced from the support plate 4 to the direction far away from the support plate 4. As will be appreciated by those skilled in the art. The deformation of trip 7 can take place for trip 7 and buckle 6's cooperation process, takes place deformation after the side of through hole contacts buckle 6 promptly, and then the through hole card is gone into to buckle 6, and the side of last through hole resumes deformation and then makes the firm joint of trip 7 on buckle 6. The thickness of trip 7 reduces gradually from backup pad 4 to the direction of keeping away from backup pad 4, is in order to reduce the thickness with the through hole side of buckle 6 contact, and then makes deformation easier, reduces the required effort of joint, reduces operator's intensity of labour. Of course, the thickness of the joint between the hook 7 and the support plate 4 is larger to ensure the connection strength between the hook 7 and the support plate 4.

Further, a through hole 13 is formed on the bottom plate 1, the through hole 13 is located between the support plate 4 and the support rib 10, and a buckle 6 is arranged on the side wall of the through hole 13. The trip 7 can form from the bottom surface downwardly extending of backup pad 4, and through set up through-hole 13 on bottom plate 1, the trip 7 can pass through-hole 13 and buckle 6 joint. Compare in setting up buckle 6 on bottom plate 1, simple manufacture like this, through-hole 13 and buckle 6 on the bottom plate 1 can one shot forming through the punching press.

Further, the through hole 13 is a rectangular hole, the clip 6 is a square clip, and a guide surface 61 is formed on a side of the clip 6 facing the support plate 4. The shape of the through hole 13 is not limited specifically, the shape of the through hole 13 may also be circular, oval or other shapes, and any shape that can realize the through hole 13 of the present invention is within the protection scope of the present invention. Can design into the rectangular hole with through-hole 13, buckle 6 also designs into rectangular buckle 6, makes the contact surface of through-hole 13 and buckle 6 can laminate completely like this, increases the joint strength between the two. In addition, set up guide surface 61 on square buckle 6, guide surface 61 sets up from the top downward sloping of square buckle 6, and the design makes things convenient for trip 7 joint like this.

Further, the bottom plate 1 is further provided with a mounting hole 14, and the mounting hole 14 is used for fixing the bottom plate 1. Specifically, the number of the mounting holes 14 may be two, and the clamping member may be further mounted on the back plate through a threaded fastener for fixing the clamping member.

The above is only the preferred embodiment of the present invention, not limiting the patent scope of the present invention, all of which are under the technical conception of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields.
