Description

Technical Field

[0001] This utility model relates to circuit board fixture technology, and more particularly to a circuit board positioning fixture. Background Technology

[0002] After the circuit board is manufactured, it needs to be inspected. During inspection, a circuit board positioning fixture is required for clamping and positioning. Currently, most methods use bolts to push positioning blocks, which clamp the circuit board. Although this method can clamp and fix the circuit board, it uses a squeezing method, which can easily damage the circuit board. At the same time, it is not convenient for quickly positioning the circuit board. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes a circuit board positioning fixture.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A circuit board positioning fixture, comprising:

[0006] A positioning seat, wherein the positioning seat is provided with multiple positioning grooves;

[0007] A plurality of positioning components are disposed within a positioning groove, the positioning components being arranged symmetrically with each other, and each positioning component having a positioning section that mates with the positioning groove, the length of the positioning section being less than the length of the positioning groove.

[0008] In this circuit board positioning fixture of the present invention, the positioning component is composed of a positioning section, a support section, a bearing section, a spiral section, a guide arc section, and a clamping vertical section. The positioning section is arranged perpendicularly to the support section, the support section is arranged vertically, the bearing section is arranged parallel to the positioning section, the bearing section is connected to the spiral section through an arc-shaped part, and the guide arc section connects the spiral section to the clamping vertical section.

[0009] In this circuit board positioning fixture of the present invention, an elastic region is formed between the spiral segment and the clamping vertical segment.

[0010] In this circuit board positioning fixture of the present invention, the lowest surface of the clamping vertical section is located at the upper end of the bearing section.

[0011] In this circuit board positioning fixture of the present invention, the positioning segment is provided with symmetrically arranged cut surfaces, and the positioning segment is set in the positioning groove through the cut surfaces. The frictional force between the cut surfaces and the positioning groove is greater than the elastic force of the spiral segment.

[0012] The circuit board positioning fixture of this utility model has the following beneficial effects: The fixture has a compact structure and ingenious design. By changing the position of the positioning element on the positioning seat, it can support and clamp circuit boards of different sizes, thereby achieving rapid clamping of the circuit boards and facilitating inspection by operators. When installing the circuit board, the guide arc segment guides the circuit board, causing the clamping vertical segment to deform under force and shift its position. This provides elastic clamping to the circuit board, maintaining its position and ensuring its stability. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1 to 6 As shown, this circuit board positioning fixture of the present invention includes a positioning base 1 and several positioning elements 2. The positioning elements 2 are disposed on the positioning base 1, and the distance between the positioning elements 2 can be changed according to the length and width of the circuit board.

[0021] The positioning seat 1 is provided with multiple positioning grooves 3, which are arranged vertically and evenly on the positioning seat 1.

[0022] Positioning element 2 is disposed within positioning groove 3. Several positioning elements 2 are provided; in this application, positioning elements 2 are provided in four locations, such as... Figure 6 As shown, a clamping area 5 is formed between the clamping vertical section 4 on the positioning member 2 and the clamping vertical section 4. Figure 1As shown, the circuit board is placed on the support section 6, and then the clamping vertical section 4 is pushed by both sides of the circuit board, so that the clamping vertical section 4 pushes the spiral section 7 and the guide arc section 11 to deform under force, thereby clamping the circuit board in the clamping area 5 between the two positioning members 2.

[0023] Positioning elements 2 are symmetrically arranged. Each positioning element 2 has a positioning segment 8 that mates with a positioning groove 3, the length of which is less than the length of the positioning groove 3. The positioning segment 8 has symmetrically arranged cut surfaces 9, which are positioned within the positioning groove 3. The friction between the cut surfaces 9 and the positioning groove 3 is greater than the elastic force of the spiral segment 7. This allows the circuit board to push and deform the clamping vertical segment 4 without pushing the positioning element 2 within the positioning groove 3.

[0024] The positioning component 2 consists of a positioning section 8, a support section 10, a load-bearing section 6, a spiral section 7, a guide arc section 11, and a clamping vertical section 4. The positioning section 8 is perpendicular to the support section 10, which is also vertically positioned. The load-bearing section 6 is parallel to the positioning section 8 and is connected to the spiral section 7 via an arc-shaped portion 12. The guide arc section 11 connects the spiral section 7 to the clamping vertical section 4. An elastic region 13 is formed between the spiral section 7 and the clamping vertical section 4, and the lowest surface of the clamping vertical section 4 is located at the upper end of the load-bearing section 6.

[0025] Before the circuit board needs to be tested, the circuit board can be pressed directly onto the positioning member 2. It is made by the bearing section 6 on the positioning member 2, and the guide arc section 11 is pushed first in the width direction of the circuit board, and then it contacts the clamping vertical section 4, so that the clamping vertical section 4 clamps the circuit board.

[0026] When the positioning component 2 is installed on the positioning base 1, the distance between the clamping vertical section 4 and the clamping vertical section 4 needs to be less than the width of the circuit board, while the distance between the connection point of the guide arc section 11 and the spiral section 7 and the connection point of the guide arc section 11 and the spiral section 7 is greater than the width of the circuit board. When installing the circuit board, the circuit board is guided by the guide arc section 11, causing the clamping vertical section 4 to deform under force and shift its position. Thus, the circuit board is clamped by the clamping vertical section 4, maintaining the position of the circuit board and ensuring the stability of the circuit board.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
