Description

Technical Field

[0001] This utility model relates to the field of steering system technology, specifically a simple tooling for rapid performance testing of PCBA circuit boards. Background Technology

[0002] In automotive steering systems, the ECU (Electronic Control Unit) is a crucial component ensuring the normal operation and functionality of the entire system, and the PCBA (Printed Circuit Board Assembly) within the ECU is a critical part of the entire control unit. Therefore, numerous performance tests are required on the PCBA to guarantee its proper functioning.

[0003] Typically, to accurately and stably measure the performance of a PCBA circuit board, it needs to be assembled within an ECU sub-assembly. The positioning of each component ensures the stability of the PCBA, accurate insertion of the measurement pins, and proper lead-out of the test leads at the connector. However, the internal connections of the ECU sub-assembly are quite complex. The entire testing process is more complicated, requires more components, and any components that fail testing must be discarded, resulting in higher costs. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this utility model provides a simple and rapid performance testing fixture for PCBA circuit boards. The PCBA circuit board to be tested is placed in the fixture, and its position is fixed by positioning posts. Then, the test pins are inserted into the pin holes on the top cover. The precise positioning of the pin holes ensures that the inserted test pins can be accurately inserted into the corresponding test points on the PCBA circuit board, thereby enabling stable and convenient testing and verification.

[0005] To achieve the above objectives, a simple PCBA circuit board performance rapid testing fixture is designed, including an upper cover and a base. The upper cover is a circular annular sleeve structure, and the base is a cylindrical sleeve structure. Positioning ribs are connected to the outer edge of the base, and several positioning posts are provided on the inner side of the base. The base is positioned and connected to the PCBA circuit board through the positioning posts on the inner side, and the base is connected to the upper cover through the positioning ribs on the outer side.

[0006] The bottom of the top cover is provided with a groove that matches the positioning rib of the base; several pin holes are provided at the top of the top cover.

[0007] The base has a circular through hole at the center of its bottom, and an annular protrusion on the upper side of the bottom of the base. The outer edge of the annular protrusion is connected to the inner wall of the base. Several positioning posts are provided on the annular protrusion.

[0008] The positioning posts are provided in at least two form, and the positioning posts are stepped columnar structures.

[0009] The upper diameter of the positioning post is smaller than the lower diameter of the positioning post.

[0010] Compared with the prior art, this utility model provides a simple and rapid performance testing fixture for PCBA circuit boards. The PCBA circuit board to be tested is placed in the fixture, and the position of the PCBA circuit board is fixed by the positioning post. Then, the test pins are inserted into the pin holes of the top cover. Through the precise position of the pin holes, it is ensured that the inserted test pins can be accurately inserted into the corresponding test points of the PCBA circuit board, thereby performing stable and convenient testing and verification.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, the upper cover 1 is a circular sleeve structure, and the base 2 is a cylindrical sleeve structure. The outer edge of the base 2 is connected to the positioning rib 2-1, and the inner side of the base 2 is provided with several positioning posts 2-2. The base 2 is positioned and connected to the PCBA circuit board 3 through the inner positioning posts 2-2, and the base 2 is connected to the upper cover 1 through the outer positioning rib 2-1.

[0019] The bottom of the top cover 1 is provided with a groove that matches the positioning rib 2-1 of the base 2; and several pin holes 1-1 are provided on the top of the top cover 1.

[0020] The bottom center of the base 2 has a circular through hole, and the upper side of the bottom of the base 2 has a circular protrusion 2-3. The outer edge of the circular protrusion 2-3 is connected to the inner side wall of the base 2. Several positioning posts 2-2 are provided on the circular protrusion 2-3.

[0021] There are at least two positioning posts 2-2, and the positioning posts 2-2 are stepped columnar structures.

[0022] The upper diameter of positioning post 2-2 is smaller than the lower diameter of positioning post 2-2.

[0023] like Figure 2 , Figure 3 As shown, the PCBA circuit board 3 is positioned and installed with the lower base 2 via two positioning posts 2-2 on the base 2. Then the upper cover 1 is installed with the base 2. First, a small gap is formed around the perimeter for fit. On the side of the fit, the positioning rib 2-1 ensures that the upper cover 1 cannot rotate.

[0024] like Figure 4 As shown, most PCBA circuit boards can be quickly tested using this base 2 and top cover 1.

[0025] like Figure 6 As shown, since the test points of most PCBA circuit boards are in relatively uniform positions, when the PIN pin hole 1-1 is opened on the top cover 1, the position is consistent with the test point of the PCBA circuit board. Then, the head of the test PIN pin 4 is a relatively hard needle shape, which can ensure vertical insertion and contact with the test point area.

[0026] The working process of this utility model:

[0027] 1. First, place the PCBA circuit board 3 into the base 2, and fix the position of the PCBA circuit board 3 using the positioning posts 2-2 (the PCBA circuit board 3 has corresponding positioning holes; simply fit the positioning holes on the PCBA circuit board 3 into the corresponding positioning posts 2-2 to fix the PCBA circuit board 3 and prevent it from shifting during testing). Figure 2 , Figure 3 As shown;

[0028] 2. Then, the upper cover 1 is connected by the groove that mates with the positioning rib 2-1 of the base 2. After the position is determined, the cover is put on.

[0029] 3. Next, insert the test PIN 4 into the PIN hole 1-1 of the upper cover 1. Ensure the precise positioning of the PIN hole 1-1 guarantees that the inserted test PIN 4 is accurately inserted into the corresponding test point position on the PCBA circuit board 3. Then, pour hot melt glue into the PIN hole 1-1 to ensure the inserted test PIN 4 stands upright and is fixed in the PIN hole 1-1 of the upper cover 1. This allows for stable and convenient testing and verification. Figure 5 , Figure 6 As shown.
