As shown in fig. 1 to 5, a radio frequency test fixture 100 for an electronic device according to an embodiment of the present application includes: fixing base 1, radio frequency connector 2 and fixed subassembly 3. Optionally, the electronic device may be a mobile phone, a tablet computer, etc., and the electronic device has a radio frequency function, and the radio frequency test fixture 100 is used in a radio frequency test of the electronic device.
Specifically, a mounting hole is formed in the fixing base 1, the mounting hole penetrates through the fixing base 1 along the thickness direction of the fixing base 1, the radio frequency connector 2 is used for connecting a main board and a testing instrument of the electronic equipment, the radio frequency connector 2 comprises a main body portion 21 and a mounting lug 22 formed at a first end of the main body portion 21, a second end of the main body portion 21 is suitable for penetrating through the mounting hole, and the mounting lug 22 is suitable for being abutted to the fixing base 1.
The fixed component 3 is arranged on the fixed seat 1, the fixed component 3 comprises a movable piece 31, a fixed piece 32 and an elastic piece 33, the first end of the elastic piece 33 is connected with the fixed piece 32, the second end of the elastic piece 33 is connected with the movable piece 31, the fixed piece 32 is connected with the fixed seat 1, and a part of the movable piece 31 is propped against the mounting lug 22. The movable member 31 is movable relative to the fixed member 32, for example, the movable member 31 can move up and down, the movable member 31 can also rotate, and the rotation surface of the movable member 31 is perpendicular to the expansion and contraction direction of the elastic member 33. The elastic member 33 is in a compressed state so that the movable member 31 presses the mounting lug 22 against the fixed base 1. Thereby, the elastic pressure applied to the movable member 31 by the elastic member 33 is directed toward the mounting lug 22, so that the mounting lug 22 can be pressed against the fixing base 1, and the radio frequency connector 2 can be fixed to the fixing base 1.

By the fixing mode, the mounting lugs 22 of the radio frequency connector 2 can be stressed uniformly, so that the radio frequency connector 2 is fixed more stably, and the reliability of testing is improved. When the radio frequency connector 2 is disassembled, the movable piece 31 is moved or rotated to separate the radio frequency connector 2 from the movable piece 31, and then the radio frequency connector 2 is taken out of the mounting hole.

Thus, the fixing unit 3 is configured as described above, and the force applied to the sleeve portion 311 toward the mounting lug 22 by the elastic member 33 (the force applied to the sleeve portion 311 downward by the elastic member 33, see fig. 1) is transmitted to the mounting lug 22 by the fixing arm 314, so that the radio frequency connector 2 can be fixed to the fixing base 1.
And, the movable member 31 can move up and down and rotate along the horizontal direction relative to the fixed member 32, when the radio frequency connector 2 is installed, the movable member 31 can be rotated horizontally to avoid the installation space, after the radio frequency connector 2 is installed to the set position, the movable member 31 is rotated horizontally to enable the fixed arm 314 of the movable member 31 to move towards the installation lug 22 of the radio frequency connector 2, the movable member 31 is lifted upwards by overcoming the downward elastic force of the spring, so that the bottom surface of the fixed arm 314 is higher than the upper surface of the installation lug 22, interference friction with the installation lug 22 in the rotation process of the fixed arm 314 is prevented, then the movable member 31 is continuously rotated to enable the free end of the fixed arm 314 to face the installation lug 22, the movable member 31 is released, and the movable member 31 enables the fixed arm 314 to press the installation lug 22 downwards under the elastic pressure of the elastic member 33. When the radio frequency connector 2 is detached, the movable member 31 is lifted upwards against the downward elastic force of the elastic member 33, so that the bottom surface of the fixed arm 314 is higher than the upper surface of the mounting lug 22, the fixed arm 314 is separated from contact with the mounting lug 22, interference friction with the mounting lug 22 in the rotation process of the fixed arm 314 can be prevented, then the movable member 31 is rotated, the fixed arm 314 of the movable member 31 moves towards a direction away from the mounting lug 22, after the fixed arm 314 rotates a certain angle (for example, the fixed arm 314 is staggered with the mounting lug 22 in the up-down direction), the movable member 31 can be released, and after the movable member 31 is released, the fixed arm 314 can be continuously rotated to a position which does not affect the next installation of the radio frequency connector 2 as required.
In addition, by providing a reasonable gap between the elastic member 33 and the inner peripheral wall of the sleeve portion 311, not only the movable member 31 can move up and down relative to the fixed member 32 and rotate in the horizontal direction, but also the up and down movement of the movable member 31 can be well guided, so that the purpose that the fixed arm 314 of the movable member 31 vertically presses the mounting lug 22 of the radio frequency connector 2 is achieved, and thus the stress of the mounting lug 22 can be further made uniform and stable.
