Abstract
The utility model discloses a testing plate for PCB plates. The utility model mainly comprises a supporting seat, a clamp layer dividing plate, a supporting rod, pads and an extruding strip, wherein, the supporting seat is arranged on the periphery of the clamp layer dividing plate, the supporting rod is arranged in the middle of the clamp layer dividing plate, the supporting seat is composed of a set of clamp layer dividing blocks and a reinforcing supporting post, and the extruding strip is tightly abutted on the supporting rod and is arranged in a groove hole of the clamp layer dividing late. When the utility model is used, a convex post on each of the clamp layer dividing block is inserted in a groove of the other clamp layer dividing block to be located through a hole of the clamp layer dividing plate. In this way, the size of each hole on the clamp layer dividing plate is identical, and the utility model has the advantages of simple structure and simple manufacturing process. In addition, the arrangement of the opening groove hole enables the clamp layer dividing blocks to be replaced more easily. What's more, each of the clamp layer dividing blocks is separated, and the clamp layer dividing blocks can be added or reduced according to requirements. The combination of the supporting rod in the middle and the extruding strip increase supporting force to the clamp layer dividing plate, the stability of clamps is enhanced, and additionally, the height of clamps can be adjusted through the addition and the reduction of the pads.
Description
Technical field
The utility model relates to a kind of Testing apparatus, refers to a kind of pcb board test fixture especially.
Background technology
Existing P CB board test fixture as shown in Figure 1, it mainly comprises: supporting seat 1, anchor clamps demixing plate 2, support bar 3 formed, and supporting seat 1 is one of the forming, and it is configured as the tower shape, its be located at anchor clamps demixing plate 2 around, in the middle of support bar 3 is located at.Because the structure of supporting seat 1, make that set hole size differs on each anchor clamps demixing plate 2, like this, technology is increased, i.e. the making of anchor clamps demixing plate quite bothers; In addition, when the closeer need of the density of survey pcb board increase the number of plies of anchor clamps demixing plate 2, must make supporting seat 1 again, change inconvenience, cost is increased.Moreover support bar is cylindrical, when installing in the centre middle layer anchor clamps demixing plate is not had anchorage force, thereby the stability of test fixture do not strengthened, and can't adjust for the anchor clamps height in addition.
The utility model content
The purpose of this utility model is to provide the pcb board test fixture that a kind of technology is simple, change easily and can increase as required or reduce the anchor clamps demixing plate number of plies.
For achieving the above object, solution of the present utility model is: a kind of pcb board test fixture, it mainly comprises supporting seat, anchor clamps demixing plate, support bar, supporting seat is located at the periphery of anchor clamps demixing plate, support bar is located at the centre of anchor clamps demixing plate, and wherein: described supporting seat is made up of one group of anchor clamps hierarchical block.
Described anchor clamps hierarchical block upper end is provided with projection, and the lower end is provided with and another set projection corresponding groove in anchor clamps hierarchical block upper end, and the anchor clamps demixing plate is provided with the hole that can supply projection to pass.
Described pcb board test fixture, it also includes the reinforcement pillar, also is provided with slotted eye on the described anchor clamps hierarchical block, strengthens pillar and is located in the slotted eye.
Described anchor clamps hierarchical block slotted eye is configured as the opening shape.
Described pcb board test fixture, it also comprises the pad that a profile is identical with the anchor clamps hierarchical block.
Described pcb board test fixture, it also includes extrusion, and described extrusion is located in the slotted eye of anchor clamps demixing plate near support bar.
After adopting said structure, because supporting seat is made up of one group of anchor clamps hierarchical block and a support bar, the hole that the projection of each anchor clamps hierarchical block passes the anchor clamps demixing plate is inserted in the groove location of another anchor clamps hierarchical block, like this, hole size on the anchor clamps demixing plate is all the same, and structure and technology are simple, in addition, the setting of opening slotted eye, it is easier that the anchor clamps hierarchical block is changed; Moreover, because each anchor clamps hierarchical block all is independently, can increase and decrease as required; The combination of intermediate supports bar and extrusion has increased the anchorage force to the anchor clamps demixing plate, has strengthened the stability of anchor clamps, also can adjust the anchor clamps height by the increase and decrease of pad in addition.

Embodiment
To shown in Figure 6, the utility model discloses a kind of pcb board test fixture as Fig. 2, it mainly comprises supporting seat 1, anchor clamps demixing plate 2, support bar 3, pad 4 and extrusion 5; Supporting seat 1 is located at the periphery of anchor clamps demixing plate 2, and support bar 3 is located at the centre of anchor clamps demixing plate 2, wherein:
Described supporting seat 1 is made up of one group of anchor clamps hierarchical block 11 and reinforcement pillar 12, anchor clamps hierarchical block 11 upper ends are provided with projection 111, the lower end is provided with and another set projection 111 corresponding groove 112 in anchor clamps hierarchical block upper end, anchor clamps demixing plate 2 is provided with the hole 21 that can supply projection 111 to pass, also be provided with opening slotted eye 113 on the anchor clamps hierarchical block 11, strengthen pillar 12 and pass slotted eye 113 and hole 22.
During use, because supporting seat 1 is made up of one group of anchor clamps hierarchical block 11 and reinforcement pillar 12, the hole 21 that the projection 111 of each anchor clamps hierarchical block passes anchor clamps demixing plate 2 is inserted in groove 112 location of another anchor clamps hierarchical block, and like this, hole 21 sizes on the anchor clamps demixing plate are all the same, structure and technology are simple, strengthen pillar 12 and be located in the opening slotted eye 113, anchor clamps demixing plate 2 is provided with for strengthening the hole 22 that pillar 12 passes, in addition, the setting of opening slotted eye 113, it is easier that anchor clamps hierarchical block 11 is changed; Moreover, because each anchor clamps hierarchical block 11 all is independently, when the bigger less need of density that need increase anchor clamps demixing plate 2 or pcb board of density of pcb board reduce anchor clamps demixing plate 2, it can increase and decrease as required, and can joint sheet 4 between the hierarchical block that reduces, increase strength of joint, can adjust the used thickness of intermediate section laminate in addition by pad 4, demixing plate such as available 0.5mm replaces the demixing plate of 1.0mm to reduce cost, can adjust the anchor clamps height by the increase and decrease of pad 4 simultaneously, extrusion 5 and support bar 3 are located in the middle of the anchor clamps demixing plate.
