Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Please see Figure 1 and Figure 2 This embodiment provides a waterproof radio frequency coaxial connector that is easy to assemble, including a conductive housing 1, a first insulating component 2, a center terminal 3, a mounting tail plug 4, and a protective tail tube 5.

[0021] A mounting cavity 1a is formed within the conductive housing 1, and the mounting cavity 1a has two oppositely disposed ends, a first end and a second end. Preferably, threads are formed on the outer side of the metal housing for connecting the conductive housing 1 to the device to be mounted.

[0022] The first insulating member is disposed in the mounting cavity 1a. The first insulating member and the conductive housing 1 are limited by a stepped structure, that is, the first insulating member extends outward to form a flange, and a step is formed on the inner side of the mounting cavity 1a. The two cooperate to allow the first insulating member to be installed from one side of the mounting cavity 1a, but not from the other side. The orientation of the step determines the direction in which the first insulating member can be installed. In this embodiment, the first insulating member 2 is installed from the second side of the mounting cavity 1a.

[0023] The center terminal 3 is inserted into the first insulating member 2. The side of the center terminal 3 near the second end of the mounting cavity 1a is used to rivet the first connecting layer A1. Specifically, the side of the center terminal 3 near the second end of the mounting cavity 1a has a first connecting hole 3a. The first connecting hole 3a is used to insert the first connecting layer A1. The outer periphery of the side of the center terminal 3 facing the first connecting hole 3a is used to rivet the first connecting layer A1 and the center terminal 3. By applying riveting pressure to the outer periphery of the side of the center terminal 3 facing the first connecting hole 3a, the center terminal 3 can be connected to the first connecting layer A1, that is, the first connecting layer A1 and the center terminal 3 are electrically connected.

[0024] Preferably, a second connection hole 3b is provided on the side of the center terminal 3 near the first end of the mounting cavity 1a. The second connection hole 3b is used to make contact and conduct with the terminal on the device to be connected.

[0025] One end of the mounting plug 4 is connected to the conductive housing 1 at the second end of the mounting cavity 1a, and the other end is used to rivet the second connecting layer. Specifically, the outer side of the mounting plug 4 away from the conductive housing 1 is recessed inward to form a mounting step 4a, and the periphery of the mounting step 4a is used to abut against the second connecting layer.

[0026] One end of the protective tail tube 5 is connected to the mounting tail plug 4, and the other end is used to sleeve and protect the outer insulation layer A4. Preferably, the protective tail tube 5 abuts against the end side of the mounting step 4a. During installation, the second connecting layer is sleeved on the outside of the mounting tail plug 4, and then the protective tail tube 5 is sleeved on the outside of the second connecting layer and the outer insulation layer A4. Riveting pressure is applied to the outside of the protective tail tube 5 to rivet the second connecting layer to the mounting tail plug 4 and the protective sleeve together, thus realizing the electrical connection between the second connecting layer and the mounting tail plug 4.

[0027] Preferably, the waterproof RF coaxial connector that is easy to assemble also includes a second insulating member 7. The second insulating member 7 is disposed between the center terminal 3 and the mounting tail plug 4 to insulate the center terminal 3 from the mounting tail plug 4 and prevent the center terminal 3 from contacting and conducting with the mounting tail plug 4. The second insulating member 7 is also limited by the above-mentioned stepped structure between itself and the center terminal 3 and the mounting tail plug 4, which will not be described in detail here.

[0028] Preferably, the device also includes a sealing ring 6. A flange is formed by extending outward from the side of the center terminal 3 near the second end of the mounting cavity 1a. The sealing ring 6 is fitted onto the center terminal 3, and its two end faces abut against the flange end face of the center terminal 3 and the end face of the first insulating member 2, respectively. More preferably, the side of the sealing ring 6 away from the first insulating member 2 abuts against the mounting tail plug 4. After being compressed by the center terminal 3 and the mounting tail plug 4, the inner two end faces of the sealing ring 6 abut against the first insulating member 22 and the center terminal 3, respectively, and the outer two end faces of the sealing ring 6 abut against the first insulating member 22 and the center terminal 3, respectively, thereby sealing and isolating the first end and the second end of the mounting cavity 1a, thus improving waterproof performance.

[0029] Preferably, the easy-to-assemble waterproof RF coaxial connector further includes a sealing tube 8, which covers the outside of the protective tail tube 5, with one end abutting against the mounting tail plug 4 and the other end abutting against the outer insulation layer A4. The end face of the sealing tube 8 can extend to the end face of the mounting tail plug 4 to increase the protection range. The sealing tube 8 can be a heat shrink tube, which shrinks when heated and tightly adheres to the mounting tail plug 4, the protective tail tube 5 and the outer insulation layer A4 to improve waterproof performance.

[0030] The following is a brief description of the assembly process of the waterproof RF coaxial connector provided in this application, which is easy to assemble: First, the protective tail tube 5 is fitted onto the outside of the cable A. The layers of the cable A are then peeled off to expose the structure of each layer. Then, the mounting tail plug 4 and the second insulating component 7 are sequentially fitted in. The first connecting layer A1 is inserted into the first connecting hole 3a, and the outer side of the center terminal 3 is riveted to rivet the center terminal 3 and the first connecting layer A1 together. Next, the first insulating component 2 and the sealing ring 6 are sequentially installed into the mounting cavity 1a from the second side. The center terminal 3 is inserted into the first insulating component 2, and the mounting tail plug 4 is pushed, causing the outer side of the sealing ring 6 to be deformed by compression. At the same time, the mounting tail plug 4 sequentially pushes the second insulating component 7 and the center terminal 3 to move, and compresses the inner side of the sealing ring 6, so that the sealing ring 6 can seal the first and second sides of the mounting cavity 1a. The mounting tail plug 4 and the conductive housing 1 can be connected by an interference fit and a threaded connection. Generally, the mounting tail plug 4 and the conductive housing 1 are also conductive. The second connecting layer is brought into contact with the mounting tail plug 4, and then the protective tail tube 5 is moved to cover the second connecting layer. Then, riveting pressure is applied to the outside of the protective tail tube 5 so that the second connecting layer, the mounting tail plug 4 and the protective tail tube 5 are riveted together, thus completing the installation.

[0031] In summary, this application provides a waterproof RF coaxial connector that is easy to assemble. During installation, the first connecting layer A1 is riveted to the center terminal 3, and the second connecting layer is riveted to the mounting plug 4 and the protective tail tube 5. Assembly is convenient, does not use welding, and is cleaner and more environmentally friendly. The protective tail tube 5 is sleeved on the outside of the cable A, which can provide protection for the cable A, reduce the lateral tensile force on the second connecting layer, and prevent the connection between the second connecting layer and the mounting tail tube from breaking due to stress caused by frequent use.

[0032] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
