Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] like Figure 1-4 As shown, the embodiments of this utility model include:

[0018] An EOL testing device for a Bluetooth module includes a shielding base shell 1, a pivot 2, a shielding cover flip 3, an electric push rod 4, internal and external corner flanges 5, a testing fixture 6, and a heavy-duty connector 7. The shielding base shell 1 has an enclosed structure and an open surface 1a with an upward opening. The shielding base shell 1 is movably connected to the shielding cover flip 3 via the pivot 2. The shielding cover flip 3 covers the entire open surface 1a. Electric push rods 4 connected to the shielding cover flip 3 are provided on both sides of the shielding base shell 1. The shielding base shell 1 and the shielding cover flip 3 are respectively provided with internal and external corner flanges 5 that fit together along the edge of the open surface 1a. The testing fixture 6 is built into the shielding base shell 1, and the heavy-duty connector 7 is provided on the back side of the shielding base shell 1.

[0019] The corner flange 5 is provided with at least two layers of right-angle steps 5a.

[0020] Furthermore, the test fixture 6 consists of a sloping platform 6a and a quick-change template 6b. The sloping platform 6a has a slope parallel to the opening, and a number of positioning pins 6c are provided on the slope. The quick-change template 6b is placed on the slope through the positioning pins 6c.

[0021] Furthermore, the quick-change template 6b is provided with a product limiting seat 8, and a hollow space 8a is opened in the center of the product limiting seat 8. A Bluetooth antenna 9 is provided in the hollow space 8a of the quick-change template 6b. A photoelectric sensor 10 is installed in the side opening of the product limiting seat 8. The top of the Bluetooth antenna 9 is matched at a position not exceeding the light field height of the photoelectric sensor 10.

[0022] Furthermore, the quick-change template 6b is provided with a slide cylinder 11, the slide cylinder 11 is equipped with a U-shaped wire harness bracket 12, the wire harness bracket 12 is provided with a spring buffer 13 that is axially parallel to the slide cylinder 11, the front end of the spring buffer 13 is equipped with an electrical connector 14, and the electrical connector 14 is matched and connected to the test fixture 6 through the slide cylinder 11.

[0023] Furthermore, the quick-change template 6b is provided with positioning mounting holes, and the Bluetooth antenna 9 is fixed on a positioning bracket 9a. The positioning bracket 9a is provided with an X-axis hole 9b and a Y-axis hole 9c that match the positioning mounting holes.

[0024] This device is used for end-of-life (EOL) testing of automotive Bluetooth modules. The method of use involves placing the Bluetooth module under test (DUT) on the product limiting seat 8. The surface of the product limiting seat 8 is equipped with positioning pins, which limit the DUT's position. Miniature cylinders are located on both sides of the product limiting seat 8. The front end of each cylinder pushes a claw, causing the claw to act on the edge of the DUT's Bluetooth module, thus limiting and fixing it. To improve the signal reception quality and stability of the DUT's Bluetooth module, a hollow space 8a is provided inside, which further reduces signal interference between the Bluetooth antenna 9 and the DUT's Bluetooth module. The X-axis hole 9b and Y-axis hole 9c allow for fine-tuning of the Bluetooth antenna 9's position, ensuring it is accurately positioned at the signal transmission point specified by the photoelectric sensor 10. This device uses a flip-top shielding cover. To further enhance the shielding cover's isolation performance, internal and external corner flanges 5 are added at the seam between the top cover and the bottom shell. Because the internal and external corner flanges 5 have at least two layers of steps 5a, the flanges overlap and fit together, accelerating signal attenuation at the seam, thereby enhancing the shielding performance. Before testing, the electrical connector 14 must be plugged into the Bluetooth module under test by the slide cylinder 11, and all wiring harnesses are led out through the heavy-duty connector 7.

[0025] In summary, this utility model provides a Bluetooth module EOL testing device, which enhances operational convenience by using a flip-top shielding cover, improves shielding effectiveness by adding internal and external corner flaps, and enhances signal stability by using a pre-embedded arrangement for the Bluetooth antenna. It also has the advantages of low cost and superior performance.
