Description

Composite Structure

technical field

The present invention relates to a composite structure, in particular to a composite structure with a clamp capable of positioning electrons.

Background technique

FIG. 1A is a perspective view of a conventional fixture N, and FIG. 1B shows a cross-sectional view of the fixture N along line a-a in FIG. 1A .

The jig N includes a base T1 and a slider T2. A recess R10 is formed on the upper surface of the base T1, and the recess R10 is used for accommodating a printed circuit board (PCB) S having a thickness s100. The slider T2 is movably arranged on the base T1, and the PCB S can be pressed against the side wall r101 of the recess R10 through the slider T2.

As shown in FIG. 1B , the slider T2 is a component with an L-shaped cross section composed of a first part t21 and a second part t22 . In a vertical direction, a distance t100 is formed between the bottom surface of the recess R10 and the position closest to the second part t22.

As far as the PCB S with thickness s100, or other single-chip or multi-chip stacked boards, the total thickness is limited by the distance t100 of the slider T2. In other words, if the thickness of the single or multiple stacked boards is slightly greater than the distance t100, the fixture N cannot be used.

Detailed ways

FIG. 2A shows a perspective view of a composite structure W according to the present invention, and FIG. 2B shows an exploded view of the composite structure W in FIG. 2A . The composite structure W includes a first body S and a second body M, wherein the first body S is disposed on the second body M, and the first body S is positioned through the second body M. In this embodiment, the first body S is a printed circuit board (PCB) (or other electronic components) with a thickness s100, and the second body M is a fixture (or a workstation).

As shown in FIG. 2B , the fixture M includes a rectangular platform 1 , a slider 2 and two elastic devices 3 . In this embodiment, the elastic device 3 is a spring.

The platform 1 includes an upper surface 100 u , a concave portion 10 , a base portion 100 , a guiding portion 11 and a positioning portion 101 . The recessed portion 10 is located on the upper surface 100u, and the PCB S is accommodated through the recessed portion 10. The base portion 100 is the bottom surface of the recessed portion 10, and the accommodated PCB S is supported through the base portion 100. The positioning portion 101 is a sidewall of the recessed portion 10 , and the guiding portion 11 is another recessed portion opposite to the positioning portion 101 and connected to the recessed portion 10 , which includes two guiding surfaces 111 , 112 spaced apart from each other.

3A shows a perspective view of the second body M of FIG. 2A, FIG. 3B shows an exploded view of the second body M of FIG. 3A, and FIG. 4 shows a cross-sectional view of the combined structure W along line b-b in FIG. 2A.

As shown in FIG. 3A and FIG. 3B , a slider 2 is movably arranged on the platform 1 . The slider 2 includes an inclined portion 200, and the inclined portion 200 is used to abut the PCB S against the positioning portion 101, so that the PCB S is clamped between the inclined portion 200 and the positioning portion 101 of the slider 2, and is guided The two guide surfaces 111 , 112 of the part 11 guide the slider 2 . The spring 3 is disposed between the platform 1 and the slider 2 , and two ends of the spring 3 are respectively connected to the connecting portion 201 of the slider 2 and the sidewall of the recessed portion 10 . When the slider 2 is connected to the platform 1 via the spring 3 , the slider 2 can move along a predetermined direction under the guidance of the two guide surfaces 111 , 112 of the guide portion 11 .

As shown in FIG. 4 , the inclined portion 200 has an angle α relative to the concave portion 10 , that is, the angle α is formed between the inclined portion 200 and the base portion 100 of the slider 2 . In this embodiment, the angle α is substantially less than 90 degrees.

Please refer to FIG. 2B again, the PCB S includes four sidewalls s01, s02, s03 and s04. When the PCB S is positioned on the fixture M, the PCB S is clamped between the slider 2 and the positioning part 101, that is, the side walls s01 and s03 of the PCB S are pressed against the inclined parts of the slider 2 respectively 200. The positioning unit 101.

It can be seen from Fig. 4 that the spring 3 arranged between the platform 1 and the slider 2 is in a compressed state, and the force generated by the spring 3 in this compressed state acts directly on the slider 2, and then through the inclined The portion 200 clamps the PCB S, which is the so-called wedge-effect. It can be seen that, regardless of single-piece or multi-piece stacked boards, if the total thickness is greater than the thickness s100 of the PCB S, the boards can be effectively positioned and clamped by the inclined portion 200 of the slider 2. hold. Therefore, under the action of the inclined portion 200 of the slider 2, the PCB S can be stably clamped between the slider 2 and the positioning portion 101. In addition, when the slider 2 moves from a position I-I to a position II-II, the PCB S can be removed.
