[0002] As the core of electronic products, the quality and reliability of a printed circuit board (PCB) are crucial for the performance and lifespan of the products. In order to ensure the quality of the circuit board, electrical tests (open / short tests) must be carried out on the circuit board, mainly to test the connectivity (Continuity) and insulation (Isolation) of the substrate. And the electrical measurement fixture is the component that bears the electrical connection between the circuit board and the electrical measurement equipment.

[0003] In order to deal with large-sized circuit boards, such as high-order AI main boards or low-earth orbit satellite main boards with a length and width of 500 millimeters, larger fixtures and electrical measurement equipment that can cooperate with the large-sized fixtures are bound to be used. However, in this way, fixtures of existing sizes (such as standard sizes) cannot be applied to the aforementioned electrical measurement equipment, that is, electrical measurement fixtures of two different sizes cannot share the same electrical measurement equipment. Summary of the Utility Model

[0004] The purpose of the utility model is to solve various existing problems of electrical measurement fixtures, and to provide a fixture clamping seat, an electrical measurement fixture combination and an assembly board.

[0005] To achieve the above and other purposes, the utility model provides a fixture clamping seat, which includes: a clamping seat body having a clamping space; and an assembly board disposed in the clamping space, the outer edge size of the assembly board corresponding to the clamping space, and the assembly board being provided with a receiving area.

[0006] Optionally, a set of fixtures parallel to each other are provided on opposite sides of the clamping seat body, and the assembly board is slidably disposed between the set of fixtures.

[0007] Optionally, a needle plate installation area is provided in the clamping space, and the receiving area at least partially overlaps with the needle plate installation area.

[0008] Optionally, at least a part of the needle plate installation area is exposed on the assembly board.

[0009] The utility model further provides an electrical measurement fixture combination, which includes: an assembly board, the outer edge size of the assembly board corresponding to the inner edge of the clamping seat body, and the assembly board being provided with a receiving area; and a fixture disposed in the receiving area.

[0010] Optionally, it further includes the clamping seat body having a clamping space, and the assembly board is disposed in the clamping space.

[0011] The present utility model further provides an assembly board. The outer edge dimensions of the assembly board correspond to the inner edge of the clamping seat body. The assembly board is provided with a receiving area, and the receiving area can accommodate a jig for testing a circuit board.

[0012] Optionally, the assembly board has two arm portions and two slide rails that are parallel to each other. The two arm portions are clamped to form the receiving area, and the two slide rails are respectively arranged on the two arm portions.

[0013] Thus, the jig clamping seat, the electrical testing jig combination, and the assembly board of the present utility model can make jigs of existing dimensions applicable to relatively large clamping seat bodies, that is, two electrical testing jigs of different dimensions can share the same clamping seat body and detection system, without the need to replace the corresponding clamping seat body and / or detection system for electrical testing jigs of different dimensions.

[0034] In order to fully understand the present utility model, the following specific embodiments and the accompanying drawings are used to describe the present utility model in detail. Those skilled in the art can understand the purpose, features and effects of the present utility model from the content disclosed in this specification. It should be noted that the present utility model can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the inventive point of the present utility model. In addition, the drawings of the present utility model are only simple schematic illustrations and are not drawn according to actual dimensions. The following embodiments will further describe the related technical content of the present utility model in detail, but the disclosed content is not used to limit the claims of the present utility model. The description is as follows:

[0035] As Figures 1 to 3 shown, the fixture clamping seat of the embodiment of the present utility model includes: a clamping seat body 1 and an assembly plate 2.

[0036] The clamping seat body 1 has a clamping space 11 for placing the assembly plate 2 and the fixture 3, or the large fixture 3a. In this embodiment, a set of clamps 12 parallel to each other are provided on opposite sides of the clamping seat body 1, so that the assembly plate 2 can be slidably arranged between the clamps 12 along the Figure 2 arrow direction. The form of the clamp 12 is, for example, a slide rail, but the present utility model is not limited thereto.

[0037] The assembly plate 2 is arranged in the clamping space 11. The outer edge dimension of the assembly plate 2 corresponds to the clamping space 11 (the inner edge of the clamping seat body 1). The assembly plate 2 is provided with a receiving area 21, and the receiving area 21 can accommodate the fixture 3 for testing a circuit board (not shown in the figure). The assembly plate 2 is, for example, a plate-shaped object made of a light metal material, and has two arm portions 22 and two slide rails 23 that are parallel to each other. The two arm portions 22 are clamped to form the receiving area 21, and the two slide rails 23 are respectively arranged on the two arm portions 22 facing each other, so that the outer edge of the fixture 3 can be installed on the assembly plate 2 along the two slide rails 23, and then installed on the clamping seat body through the assembly plate 2.

[0038] As Figure 2 and Figure 3As shown, a needle plate mounting area 111 is provided in the clamping space 11 for placing the needle plate 32a of the large fixture 3a. The accommodating area 21 of the assembly board 2 at least partially overlaps with the needle plate mounting area 111, so that at least a part of the needle plate mounting area 111 is exposed on the assembly board 2. At the exposed place, the probes (not shown in the figure) on the needle plate 32 of the standard or relatively small fixture 3 can be electrically connected to the detection system T.

[0039] The present utility model also provides an electrical measurement fixture combination, which includes: an assembly board 2 and a fixture 3.

[0040] The fixture 3 is arranged in the aforementioned accommodating area 21. The fixture 3 may include a fixture base 31 and a needle plate 32. The fixture base 31 is used to carry the circuit board to be tested and electrically connect the circuit board to be tested to the detection system T below the needle plate mounting area 111 through the probes on the needle plate 32. Specifically, the needle plate 32 can be used to place the test probes, and the probes are used to contact the detection system T so that the electrical signal is communicated from the detection system T to the circuit board to be tested. The test items or performances can be changed by changing the probes and their positions.

[0041] Reference Figure 1 With Figure 3 , when the relatively large clamping seat body 1 is to be adapted to the relatively small fixture 3, the assembly board 2 is used in combination with the fixture 3, so that the fixture 3 is suitable for being installed on the relatively large clamping seat body 1, and the needle plate 32 is aligned with at least a part of the needle plate mounting area 111 of the clamping seat body 1. On the contrary, when the clamping seat body 1 is to be adapted to the large fixture 3a, there is no need to use the assembly board 2. The large fixture 3a can be directly installed on the clamping seat body 1 for subsequent electrical tests. At this time, the fixture base 31a of the large fixture 3a carries the circuit board to be tested, and the needle plate 32a is aligned with the needle plate mounting area 111 of the clamping seat body 1.

[0042] In summary, through the assembly board 2 of the present utility model, the existing-sized fixture 3 can be made applicable to the relatively large clamping seat body 1, that is, the two different-sized electrical measurement fixtures 3 and 3a can share the same clamping seat body 1 and detection system, and there is no need to replace the corresponding clamping seat body and / or detection system for different-sized electrical measurement fixtures.

[0043] The present utility model has been disclosed above with preferred embodiments. However, those skilled in the art should understand that the embodiments are only used to describe the present utility model and should not be construed as limiting the scope of the present utility model. It should be noted that all equivalent changes and substitutions to the embodiments should be set to be covered within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
