Description

Technical Field

[0001] The utility model relates to a tooling fixture, in particular to a power board test tooling fixture. Background Art

[0002] A power board is a component that provides the power required for a printed circuit board (PCB) to work properly. Specifically, the power board is a daughter board on the printed circuit board (PCB) and is mainly used for power conversion.

[0003] Existing test toolings for power boards often do not have independent tooling fixtures. Instead, the power board is simply placed on the boss in the integrated test area of the test tooling or in the groove of the test area.

[0004] Placing the power board on the boss can accommodate power boards of various sizes. However, since the power board is manually placed, the position of the power board is prone to deviation, affecting the accuracy of the test results. Placing the power board in the groove limits the size of the power board. When the power board is larger than the groove or does not match the groove, testing cannot be carried out, and it is necessary to purchase toolings of multiple models, resulting in relatively high costs. Moreover, it is very difficult to take out the power board that fits the size after it is placed in the groove, causing inconvenience. Summary of the Utility Model

[0005] In order to solve the deficiencies of the above technologies, the utility model provides a power board test tooling fixture.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: it includes a base plate and a cover plate that are hinged and opened and closed, and the base plate and the cover plate are also locked by snap connections;

[0007] Connection seats are arranged at both ends of the long side of the base plate. Snap grooves are formed on the corresponding side of the long side where the connection seats are located. A pin column is formed on the upper surface of the plate body of the base plate, and a hand hole is also formed on the plate body of the base plate.

[0008] On the side of the cover plate hinged to the base plate, connection feet adapted to the connection seats are formed. A power board installation avoidance area is processed between the two connection feet at both ends.

[0021] The following further describes the utility model in detail with reference to the drawings and specific embodiments.

[0022] As Figure 1-2 Collectively shown, this embodiment relates to a power supply board test fixture for clamping and locking a power supply board, including a substrate 1 and a cover plate 2 that are hinged and opened and closed. The substrate 1 and the cover plate 2 are also connected and locked by a buckle. That is to say, when the substrate 1 and the cover plate 2 are opened and closed, the power supply board is placed inside, and then the substrate 1 and the cover plate 2 are closed, and then locked through the buckle connection of the substrate 1 and the cover plate 2.

[0023] In this embodiment, connection seats 3 are provided at both ends of the long side of the substrate 1. A snap groove 11 is formed on the corresponding side of the long side where the connection seats 3 are located. As Figure 1 shown, the long side is the longest side of the substrate 1. A pin 9 is formed on the upper surface of the plate body of the substrate 1, and a hand hole 10 is also formed on the plate body of the substrate 1;

[0024] On the side where the cover plate 2 is hinged to the substrate 1, connection feet 5 adapted to the connection seats 3 are formed. Needless to say, the number of connection feet 5 corresponds to that of the connection seats 3. A power board installation avoidance area 4 is processed between the two end connection feet 5. The power board installation avoidance area 4 is used to avoid the power board and prevent it from being stuck. A test window 6 is formed on the plate body of the cover plate 2, and several pressing pad seats 7 are installed around the test window 6. A snap 8 adapted to the snap groove 11 is also formed on the plate body of the cover plate 2.

[0025] Preferably, the connection seat 3 is formed in a manner with an upward extension height. The hinge point of the connection seat 3 is located at its upper end. Due to the fact that the connection seat 3 has a vertical height and the height of the hinge point is limited, a clamping space is formed between the substrate 1 and the cover plate 2. The power board is placed in this clamping space to prevent the cover plate 2 from pressing the power board too hard and causing damage.

[0026] As Figure 1 shown, the two end connection feet 5 are located between the two end connection seats 3. The combination of each side connection foot 5 and the connection seat 3 is hinged by a connecting rod. This is the prior art.

[0027] The snap 8 is located at the edge position on the corresponding side of the power board installation avoidance area 4. Specifically, the snap 8 is located at the middle position of the entire side. Needless to say, the snap groove 11 is also located at the central position of its corresponding edge.

[0028] As Figure 1 shown, the number of pins 9 is four. The four pins 9 enclose a rectangle and are arranged in a way that each abuts against the corner of the power board. That is to say, the area enclosed by the four pins 9 is the area for placing the power board. During actual production, the four pins 9 are adapted to the positions of the four corners of the power board of its corresponding model. Therefore, each of the four pins 9 abuts against its corresponding corner, and the adaptation position is very accurate, effectively avoiding the situation where the power board is placed with deviation in the case of the traditional boss design.

[0029] The number of hand holes 10 is two. The two hand holes 10 are symmetric about the left and right and are formed in a way that each intrudes into the area enclosed by the pins 9. As Figure 1As shown, the hand buckle hole 10 is a through hole and is specifically circular, which is convenient for the operator to insert his fingers into. The number of hand buckle holes 10 is two, which is conducive to the operator's two-handed operation. The hand buckle hole 10 invades the power board placement area so that the operator's fingers can touch the power board; based on the above characteristics, when the power board is placed in its area and needs to be removed after the test is completed, the operator opens the base plate 1 and inserts his fingers into the hand buckle hole 10 from bottom to top to push the power board out.

[0030] The substrate 1 is provided with a connector area 12 in the middle of the long side of the connection socket 3 , and a test plug 13 is provided at the back of the connector area 12 . The test plug 13 is used to connect a test instrument or sensor.

[0031] The left and right sides of the substrate 1 and the position close to the side where the buckle groove 11 is located form an inwardly narrowed force avoidance area 14. When this embodiment is placed on a workbench as a whole, the force avoidance area 14 is provided to facilitate personnel to take it.

[0032] The pressing pad 7 is arranged on the side opposite to the cover plate 2 and the base plate 1 , and is implemented in a manner of abutting against the power board. In the actual production process, the pressing pad 7 can be made of rubber to abut against the power board by elastic pressing.

[0033] Based on the above structure, during the test process, the present embodiment can be placed on a workbench. When the size of the power board to be tested is different, the present embodiment of the matching size can be replaced for clamping.

[0034] Thus, the power board test fixture disclosed in the utility model innovatively sets an independent fixture compared to the traditional power board test fixture. The power board can be firmly fixed by this embodiment to avoid the occurrence of test installation position deviation. The present embodiment is convenient for personnel to take and can easily take out the power board. The present embodiment of different sizes can be adapted to power boards of different sizes, and the production cost is low.

[0035] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
