[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0020] Example 1

[0021] Figure 1 This is a schematic diagram of the overall structure of the RF module batch test fixture provided by the embodiment of the present utility model. Figure 1 As shown, the fixture includes a PCB board 1, a base 2 and an upper cover 3.

[0022] In this embodiment, the PCB board 1 is arranged on the first side of the base 2, such as below the base 2, and is connected to the bottom of the base 2 through a connecting column; the upper cover 3 is arranged on the second side of the base 2, such as above the base 2, and covers the base 2.

[0023] More specifically, the base 2 is provided with a plurality of limiting slots 201 for placing the RF module 4. The shape of the limiting slots 201 is adapted to the bottom shape of the RF module 4 to ensure the bottom stability of the RF module 4 after installation.

[0024] The PCB board 1 is provided with several module connectors 101. This PCB board 1 is a power supply control PCB circuit board, containing multiple module power supply and control circuits. The module connectors 101 are used to power the RF module 4 and send control signals. In one possible implementation, there are eight limit slots 201 and four PCB boards 1. Each PCB board 1 contains two module power supply and control circuits and is provided with two module connectors 101. The ends of the module connectors 101 extend into the limit slots 201. The module connectors 101 are responsible for powering the RF modules 4 and sending control signals to the RF modules 4 within the two limit slots 201 above them. Furthermore, in this embodiment, the interface between the module connectors 101 and the RF module 4 is defined as follows: Pins 1-2 are ±5V, Pins 3-4 are ground, Pins 5-12 are control signal data D0 to D7, Pin 13 is a clock, Pin 14 is a valid signal, and Pin 15 is a latch signal. Therefore, the fixture can test 8 RF modules 4 at the same time, greatly improving the test efficiency and reducing the test cost; in addition, the RF module 4 is connected to the module connector 101 by inserting it downward, and under the limitation of the limiting slot 201, it can effectively prevent the pins of the RF module 4 from being damaged, the appearance from being scratched, and the contact from being poor.

[0025] The upper cover 3 is provided with a plurality of positioning slots 301, the shape of which matches the top shape of the RF module 4 to ensure the stability of the top of the RF module 4 after installation; each of the module connectors 101 and the positioning slots 301 is arranged in a one-to-one correspondence with the limiting slots 201, see Figure 2 Combined with the limit slot 201 opened on the base 2, the fixture can achieve all-round clamping and fixing of the RF module 4, ensuring that the RF module 4 is not easy to loosen and fall off after installation, thereby ensuring the stability of the test.

[0026] Example 2

[0027] This embodiment is based on the technical solution provided in Example 1, and further describes the specific structure of the fixture:

[0028] Regarding the upper cover 3, in this embodiment, it is made of 1.2mm sheet metal with a U-shaped cross-section to prevent deformation. Furthermore, to prevent rigid contact between the upper cover 3 and the RF module 4, this embodiment provides a gasket 302 on the first side of the upper cover 3. Preferably, the gasket 302 is a compressed sponge.

[0029] Furthermore, the first end of the upper cover 3 is hinged to the second side of the base 2 through a damping hinge 303, and maintains an angle of 0 to 90 degrees with the base 2. Figure 3 As shown, it is convenient for installing the RF module 4; the second end of the upper cover 3 is detachably connected to the second side of the base 2 by a butterfly bolt 304. After the upper cover 3 is closed, the upper cover 3 can be quickly fixed by tightening the butterfly bolt 304 by hand, and the RF module 4 can be firmly fixed between the upper cover 3 and the base 2. The operation is very convenient and facilitates the installation of the RF module 4.

[0030] Regarding the base 2, in this embodiment, the second side of the base 2 is provided with N pads, where N is a positive integer greater than or equal to 2, including a first pad 202 provided at the first end, a second pad 203 provided at the second end, and a third pad provided in the middle, so that a mounting position for the RF module 4 is formed between the upper cover 3 and the base 2, see Figure 4 As shown; wherein, the first end of the upper cover 3 is hinged to the first cushion block 202, and the second end of the upper cover 3 is detachably connected to the second cushion block 203.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
