Embodiment 1

[0031] figure 1 A schematic diagram of the overall structure of the RF thimble for production testing provided by the embodiment of the present invention,

[0032] figure 2 For the connection diagram of the probe, the light guide and the color recognition sensor provided by the embodiment of the present invention, refer to figure 1 and figure 2 As shown, the embodiment of the present invention provides a radio frequency thimble 100 for production testing, which is used for mating connection with the test socket 200 .

[0033] Wherein, during the production test, it is necessary to coaxially set the RF thimble 100 and the test socket 200 through the RF fixture, and press down the RF thimble 100 to make contact with the coaxial connector test socket 200 to test the RF signal.

[0034] During the production test process, there are many reasons for the poor RF signal test, which may be the design of the RF fixture, the electrical performance failure of the main board, or the ...

Embodiment 2

[0058] Embodiment 2 of the present invention provides a radio frequency test system, including a test socket 200 and the radio frequency thimble 100 for production test provided in the above embodiment.

[0059] Wherein, during the production test, it is necessary to coaxially set the RF thimble 100 and the test socket 200 through the RF fixture, and press down the RF thimble 100 to make contact with the coaxial connector test socket 200 to test the RF signal.

[0060] Specifically, the radio frequency thimble 100 includes: a housing 11, a probe 12, a light-conducting member 13, and a color recognition sensor 14; 13 is installed in the accommodating hole, the first end of the light-conducting member 13 is exposed at the end of the probe 12, the second end of the light-conducting member 13 is connected with the color recognition sensor 14, and the light-conducting member 13 is used to connect the end of the probe 12 The reflected light from the reflective surface close to the e...

Abstract

The invention provides a radio frequency thimble for production test and a radio frequency test system, which are used for being connected with a test seat in a matching way, the radio frequency thimble comprises a shell, a probe, a light conduction piece and a color identification sensor; the probe is positioned in the cavity of the shell; an accommodating hole is formed in the probe; the light conduction piece is arranged in the accommodating hole; the first end of the light conduction piece is exposed at the end part of the probe; the second end of the light conduction piece is connected with the color recognition sensor, the light conduction piece is used for transmitting reflected light of the reflecting surface close to the end part of the probe to the color recognition sensor, and the color recognition sensor is used for recognizing the color of the reflected light and judging whether the end part of the probe is aligned to a terminal with a preset color of the test seat or notaccording to the color of the reflected light. The radio frequency thimble for production test and the radio frequency test system aim to solve the problem that the deviation of the radio frequency thimble is difficult to detect in the production test process in the prior art.

Description

technical field [0001] The invention relates to the technical field of radio frequency testing, in particular to a radio frequency thimble for production testing and a radio frequency testing system. Background technique [0002] During the RF production test process, it is necessary to set the RF thimble coaxially with the test socket through the RF fixture, and press down the RF thimble to make contact with the coaxial connector test socket, so as to test the RF signal. In actual use, due to the deviation of the position of the thimble, the deviation of the movement structure of the RF fixture, as a consumable material, the deviation of the RF thimble itself due to its own bending, the welding deviation of the coaxial test seat, etc., the RF thimble may not be able to accurately push into the coaxial The center of the connector, or the top to the insulation layer of the inner ring of the coaxial connector, leads to radio frequency open circuit and poor contact. [0003] I...
