Specific embodiments

[0026] The present invention will be further described in detail below with reference to the accompanying drawings. The following is an explanation of the present invention rather than a limitation. In the present disclosure, unless otherwise stated, the orientation terms such as "upper" and "lower" generally refer to those defined based on the drawing plane of the corresponding drawing, and "inner" and "outer" refer to the inside and outside of the contour of the corresponding component.

[0027] Combined with Figures 1-6 , the plug 1 of the present invention includes a plug housing 11, and at least one plug connector 12 is axially embedded in the plug housing 11. A plug axial limit connecting member 12a is sleeved on the outer wall of the plug connector 12; the plug connector 12 is provided with a radial limit housing 12b, and a plug outer conductor 12c is coaxially arranged in the radial limit housing 12b, and an annular gap is formed between the plug outer conductor 12c and the radial limit housing 12b. For example, more than two radio frequency channels are integrated on the plug 1 of the present invention. By setting the axial limit connecting member 12a, the erection of a single or multiple radio frequency channels can be realized, meeting the requirements of different connection and test functions, making it more flexible to use. And an annular gap is formed between the plug outer conductor 12c and the radial limit housing 12b, so that the plug outer conductor 12c and the radial limit housing 12b have a certain range of movement, ensuring the stability of the connection; the deflection angle of the plug outer conductor 12c relative to the radial limit housing 12b can also be controlled by the size of the annular gap. The test method is flexible, saving the test cost, and having advantages in environmental reliability such as sealing and anti-vibration. In the future field of high-performance and high-reliability integrated products, it can be widely promoted and applied. After evaluation, the product has good performance, high reliability, a flexible test method, and saves the test cost; for example Figure 3 as shown in

[0028] In addition, as Figure 2As shown, for the plug connector 12 of the present invention, a plug insulator 12d and a plug inner conductor 12e are coaxially sleeved in sequence within the plug outer conductor 12c. The protruding length at the end, the plug axial limiting connector 12a, the radial limiting housing 12b, and the plug outer conductor 12c increase in sequence. In particular, the protruding length of the plug outer conductor 12c together with the plug insulator 12d and the plug inner conductor 12e is the longest, aiming to facilitate the plug-in connection with the socket. The externally provided threaded member only needs to meet the length or function requirements for connector testing.

The radial limiting platform 12c.1 forms a gap with the radial limiting housing 12b. This gap can limit the radial deflection angle of the plug outer conductor 12c. For example, the size of the gap between the plug outer conductor 12c and the radial limiting housing 12b can be controlled by the thickness of the radial limiting platform 12c.1, thereby controlling the relative deflection angle between the two and meeting the test requirements of various connectors.

[0032] In an embodiment of the present disclosure, a keyway 11b is provided at the edge of the plug-in end of the plug housing 11, which can quickly perform plug-in positioning; an anti-rotation mechanism 11c is provided at the wiring end of the plug housing 11, which can play a role in preventing rotation in a single channel.
