Background

The circuit board can be called as a printed circuit board or a printed circuit board, and the FPC circuit board is also called as a flexible printed circuit board which is made of polyimide or polyester film as a base material and has high reliability and excellent flexibility. The high-density light-weight LED lamp has the characteristics of high wiring density, light weight, thin thickness and good bending property. And the birth and development of the FPC and the PCB of the rigid-flexible Printed Circuit Board (PCB) urge the generation of a new product of the rigid-flexible printed circuit board (FPC). Therefore, the rigid-flex circuit board is a circuit board with FPC (flexible printed circuit) characteristics and PCB (printed circuit board) characteristics, which is formed by combining a flexible circuit board and a rigid circuit board according to relevant process requirements through processes such as pressing and the like.

But at present most anchor clamps use so conveniently, can't adjust holistic size, can't work to the circuit board of equidimension not. An adjustable clamp for circuit board soldering, as disclosed in CN207083303U, can solve the above problems, but has the following disadvantages, such as: the circuit board thickness can not be the same completely, then can not be fine fix the circuit board when this anchor clamps meet the circuit board that multiple specification and thickness differ to the application scope of this equipment has been restricted, and back splint thickness is limited, sets up the guide rail groove in the lateral wall is inside, and the installation is tensile pole and the elastic component that resets at the guide rail inslot simultaneously all comparatively troublesome and the operation inconvenient, is unfavorable for the use widely of equipment.

Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

The utility model provides an anchor clamps of circuit board processing usefulness, which comprises a fixing plate 1, the fixing base 2 and the rubber packing piece of activity, it is provided with dead lever 3 to correspond on the lateral wall of 1 both sides of fixed plate, wherein 3 outside tops of dead lever are the screw rod structure, and fixing base 2 sets up on dead lever 3, and be provided with the through-hole 4 of overcoat on dead lever 3 on the fixing base 2, make 2 accessible through-holes 4 of fixing base carry out horizontal displacement on dead lever 3, because 3 cross-sections of dead lever are the hexagon, 4 internal diameter sizes of through-hole and structure all with 3 looks adaptations of dead lever simultaneously, lead to dead lever 3 to block through-hole 4, make fixing base 2 can not take place rotatory phenomenon through.

Wherein still weld the sleeve pipe 5 of overcoat on dead lever 3 in fixing base 2 outside bottom to 5 internal diameters of sleeve pipe size and structure all with dead lever 3 looks adaptations, through sleeve pipe 5 increase with the dead lever 3 between area of contact, reduce fixing base 2 and take place rotatory probability on dead lever 3, increase the steadiness between the two simultaneously.

And the fixed link 3 outside the sleeve 5 is sequentially provided with a spring I6 and a nut I7, and the spring I6 is sheathed on the fixed link 3, wherein the nut I7 is screwed on the screw structure at the top end outside the fixed link 3, so that the nut I7 can lock the spring I6 on the fixed link 3 without falling off, meanwhile, the unfolded spring I6 can press the fixed seat 2 to the outer side wall of the fixed plate 1 through the sleeve 5, and the circuit board clamped by a plurality of groups of fixed seats 2 is clamped and fixed at the top of the fixed plate 1, when in work, the fixed seat 2 is pulled outwards and the through hole 4 and the sleeve 5 are driven to move outwards and horizontally on the fixed link 3, at the moment, the sleeve 5 extrudes the spring I6 to contract, and the nut I7 supports the tail end of the spring I6 to prevent the spring I6 from sliding out from the fixed link 3, thereby realizing the expansion of the space between the two groups of corresponding fixed seats, then slowly loosen the fixing base 2, the stretched spring I6 can press the fixing base 2 to the outer side wall of the circuit board through the sleeve 5, and the circuit board clamped by the multiple groups of fixing bases 2 is clamped and fixed at the top of the fixing plate 1.

Meanwhile, a supporting block 8 is bent from the top end of the fixing seat 2 towards the position right above the fixing plate 1, wherein a circular hole 9 is formed in the supporting block 8, a screw rod 10 is arranged in the circular hole 9, a nut II11 positioned at the top of the supporting block 8 is screwed at the top end of the screw rod 10, an L-shaped clamping piece 13 is welded at the bottom end of the screw rod 10, a spring II12 is sleeved outside the screw rod 10 positioned between the supporting block 8 and the clamping piece 13, the supporting block 8 abuts against the top end of the clamping piece 13 through a stretched spring II12 when in use, so that the screw rod 10 is prevented from moving upwards in the circular hole 9, at the moment, the nut II11 can prevent the top end of the screw rod 10 from sliding downwards out of the circular hole 9 due to excessive stretching of the spring II12, as shown in fig. 3, the long-side end of the clamping piece 13 is positioned at the inner side of the supporting block 8, it also prevents spring II12 from being stretched too far and causing the top end of screw 10 to slide downward out of circular hole 9.

In this embodiment, when a circuit board with a thicker thickness is encountered during use, as shown in fig. 4, the clip 13 is moved upward to drive the screw 10 to move upward in the circular hole 9, and the spring II12 is simultaneously squeezed to contract, so as to expand the distance between the clip 13 and the top end of the fixing plate 1, and simultaneously place the circuit board on the fixing plate 1 at the bottom of the clip 13, and then slowly put down the clip 13 to make the spring II12 expand to drive the screw 10 to move downward in the circular hole 9, and at this time, the bottom end of the clip 13 abuts against the top end of the circuit board to press the circuit board on the fixing plate 1.

As an optimal scheme, all bond rubber gasket on the lateral wall of clamping piece 13 and 2 inside walls of fixing base, wherein the edges and corners of the bending part of clamping piece 13 are provided with the fillet.
