Detailed Implementation

[0018] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figures 1 to 3 As shown, the reverse polarity floating TMA RF coaxial connector of this utility model includes: a first housing 1 having an axially extending receiving channel 11, the receiving channel 11 having a first portion 111 and a second portion 112, the inner diameter of the second portion 112 being larger than the inner diameter of the first portion 111, a first conductor 3 being installed in the first portion 111 through a first insulating medium 2, and an elastic element 4 being provided in the second portion 112; a second housing 5 being at least partially located in the second portion 112 of the first housing 1, the second housing 5 being pushed to a stationary position by means of the elastic force of the elastic element 4, and a second conductor 7 being installed in the second housing 5 through a second insulating medium 6.

[0022] See Figure 1 , Figure 2 The first housing 1 has a receiving channel 11 extending through it along its axial direction. The receiving channel 11 has a first part 111 and a second part 112. The inner diameter of the first part 111 is smaller than the inner diameter of the second part 112. An elastic member 4 is placed in the second part 112 of the receiving channel 11. A first conductor 3 is installed in the first part 111 of the receiving channel 11 by means of a first insulating medium 2. A second housing 5 is installed in the second part 112 of the receiving channel 11. A second conductor 7 is installed in the second housing 5 by means of a second insulating medium 6. One end of the second conductor 7 extends out of the second housing 5 near the end of the elastic member 4. The two ends of the elastic member 4 are respectively abutted against the inner wall of the first part 111 of the first housing 1 and the outer wall of the second housing 5. It should be noted that the first housing 1, the second housing 5, the first conductor 3 and the second conductor 7 are coaxial. The first conductor 3 has a groove on the side facing the second conductor 7 for the first conductor 3 to enter.

[0023] See Figure 1In the initial state, under the action of the elastic element 4, the second housing 5 is pushed to a stationary position away from the first conductor 3 by the elastic element 4. At this time, the end of the second conductor 7 does not enter the groove of the first conductor 3. When adjusting the RF coaxial connector of this application, since the second housing 5 has a movement gap in the second part 112 of the accommodating channel 11 of the first housing 1, the second housing 5 can float axially in the second part 112 of the accommodating channel 11. When the connector deviates or experiences vibration and impact during use, the elastic element 4 can provide a certain buffering force to ensure the stability of the RF coaxial connector of this application.

[0024] In one or more embodiments, a stop 8 is installed at the opening of the second part 112 of the accommodating channel 11 in the first housing 1. The stop 8 has an eave 81 extending in the axial direction. An annular portion 51 is provided on the outer periphery of the second housing 5. When the elastic member 4 pushes the second housing 5 to a stationary position through the annular portion 51, the annular portion 51 of the second housing 5 abuts against the eave 81 of the stop 8. The stop 8 is threadedly connected to the second part 112 of the first housing 1.

[0025] See Figure 1 The stop member 8 is threaded onto the opening of the second portion 112 of the accommodating channel 11 in the first housing 1. The stop member 8 has an opening through which the second housing 5 passes. An eave 81 is formed at the opening of the stop member 8. The inner diameter of the eave 81 is smaller than the outer diameter of the annular portion 51 of the second housing 5. When the annular portion 51 is located within the second portion 112 of the first housing 1 and is pressed against by the elastic member 4, the annular portion 51 can abut against the eave 81 of the stop member 8, thus limiting the second housing 5 and improving the stability of the second housing 5 installed within the first housing 1. Furthermore, by configuring the stop member 8 and the first housing 1 with a threaded connection, i.e., the stop member 8 can be disassembled from the first housing 1, it facilitates the installation of the elastic member 4 and the second housing 5 within the first housing 1, improving the assembly and disassembly efficiency of the RF coaxial connector of this application.

[0026] In one or more embodiments, the inner side of the eaves 81 of the stop member 8 has a guide portion 82 with a gradually increasing inner diameter.

[0027] See Figure 1 When the second housing 5 floats along the axial direction, under the action of the elastic member 4, the annular portion 51 of the second housing 5 moves toward the eaves 81. When the axis of the second housing 5 deviates from the axis of the first housing 1, that is, when the second housing 5 moves radially, the annular portion 51 of the second housing 5 can press against the guide portion 82 of the eaves 81. With the help of the elastic force of the elastic member 4 and the guiding action of the guide portion 82, the position of the second housing 5 in the first housing 1 gradually returns to the correct position, ensuring that the product does not become misaligned due to the gap required for radial floating in the free state.

[0028] In one or more embodiments, the materials of the first insulating medium 2 and the second insulating medium 6 are PTFE.

[0029] See Figure 1 The first insulating medium 2 and the second insulating medium 6, made of PTFE material, have a low dielectric constant, which can ensure mechanical fixation of the first conductor 3 and the second conductor 7 while reducing the delay of radio frequency signals during transmission and improving the signal propagation efficiency, thus possessing practicality.

[0030] In one or more embodiments, a first barb structure 12 is provided in the first part 111 of the first housing 1, and the first insulating medium 2 is clamped in the first housing 1 by the first barb structure 12; a second barb structure 52 is provided in the second housing 5, and the second insulating medium 6 is clamped in the second housing 5 by the second barb structure 52.

[0031] See Figures 1 to 3 The first insulating medium 2 is secured in the first housing 1 by means of the first barb structure 12, and the second insulating medium 6 is secured in the second housing 5 by means of the second barb structure 52. This arrangement can improve the installation strength of the first insulating medium 2 and the second insulating medium 6 and improve the service life of the radio frequency coaxial connector of this application.

[0032] In one or more embodiments, a third housing 9 is further included, disposed within the receiving channel 11 of the first housing 1, with a first end of the third housing 9 abutting against the first portion 111 and a second end of the third housing 9 extending into the second portion 112. See also Figure 1 By configuring the second end of the third housing 9 to extend into the second portion 112 of the receiving channel 11, the distance by which the end of the second housing 5 extends into the second portion 112 of the first housing 1 is limited, thus avoiding the problem of excessive compression of the elastic element 4 and excessive contact between the first conductor 3 and the second conductor 7.

[0033] In one or more embodiments, a stepped layer is provided in the first part 111, and the first end of the third housing 9 abuts against the stepped layer to limit the position of the third housing 9 inside the first housing 1.

[0034] In one or more embodiments, the elastic element 4 is a spring or elastic steel.

[0035] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
