Description

Technical Field

[0001] The present invention relates to the technical field of feeder connectors, and in particular to a radio frequency coaxial feeder connector and an application method thereof. Background Art

[0002] The feeder connector is a component installed on a cable or an instrument as a component for transmitting electrical connection or separation. In the existing technology, the front shell and the rear shell on the feeder connector are connected by threads, which needs to be installed during high-altitude operations, thereby reducing the efficiency of installation. In addition, when the cable and the feeder connector are connected, one end of the cable needs to strip the outer shell of the corresponding length to expose the outer conductor of the cable, and then the rear shell is put on the outer conductor of the cable, and the outer conductor of the cable is cut along the cable clamp and turned over to fit the cable clamp, and then the head end of the outer conductor of the cable continues to strip the cable core of the corresponding length, and finally the cable core is inserted into the front shell, and the front shell and the rear shell are fixedly connected by threads. This method reduces the convenience of installation, increases the time of installation, and reduces the efficiency of installation. To this end, a radio frequency coaxial feeder connector and an application method thereof that improves the convenience of installation are proposed. Summary of the invention

[0003] The purpose of the present invention is to solve the above problems and to provide a radio frequency coaxial feeder connector and an application method thereof.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a radio frequency coaxial feeder connector, which is characterized by including a front shell, a rear shell installed on the front shell with an interference fit, a front insulator and a rear insulator installed in the front shell, and a jack installed between the front insulator and the rear insulator; the rear shell is also installed with a plurality of thrust rings for facilitating direct cable insertion and fixing the outer surface of the cable.

[0005] Preferably, the thrust ring is evenly provided with a plurality of elastic barbs for fixing the cable around the circumference.

[0006] Preferably, a bushing is installed in the front shell; and a plurality of washers for fixing the thrust ring are installed between the bushing and the rear shell.

[0007] Preferably, sealing rings are installed between the front shell and the rear shell and inside the rear shell.

[0008] Preferably, an insulating sleeve is installed in the jack.

[0009] An application method of a radio frequency coaxial feeder connector, characterized in that the application method is as follows: First, strip one end of the cable to install the cable core of the required length, and insert the end of the cable with the stripped cable core into the jack in the feeder connector, and use the multiple thrust rings in the rear shell to limit and fix the outer shell of the cable, and install the feeder connector on the cable.

[0010] The beneficial effects of the present invention are as follows: the front housing and the rear housing are installed by interference fit, and no disassembly is required during installation, thereby improving the convenience of installation and avoiding the occurrence of missing parts or insufficient parts during the construction process, thereby ensuring the construction quality; By using the thrust ring to directly limit the outer shell of the cable after insertion, the installation efficiency is improved, and the construction method in which the outer conductor of the cable is in direct contact with the outer conductor of the feeder connector is avoided. During the construction process, the copper layer of the inner core of the cable is scraped off by the jack into the inside of the connector, resulting in poor withstand voltage and poor contact between the outer conductor of the cable and the outer conductor of the feeder connector.

[0015] Hereinafter, we will further illustrate a radio frequency coaxial feeder connector and an application method thereof according to the present invention with reference to the accompanying drawings.

[0016] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0017] See attached Figure 1-3As shown, in this embodiment, a radio frequency coaxial feeder connector is characterized by comprising a front shell 1, a rear shell 2 installed on the front shell 1 by interference fit, a front insulator 3 and a rear insulator installed in the front shell 1, and a socket 5 installed between the front insulator 3 and the rear insulator; the rear shell 2 is also installed with a plurality of thrust rings 6 for facilitating direct plugging of cables and fixing the outer surface of the cables; the front shell 1 and the rear shell 2 are installed by interference fit, and no disassembly is required during installation, thereby improving the convenience of installation, avoiding missing parts during construction, and ensuring the construction quality; the thrust ring 6 is used to directly limit the outer shell of the cable after plugging, thereby improving the efficiency of installation, avoiding the situation that the outer conductor of the cable is in direct contact with the outer conductor of the feeder connector during the construction method, and the socket 5 scrapes the copper layer of the inner core of the cable into the inside of the connector, resulting in poor withstand voltage and poor contact between the outer conductor of the cable and the outer conductor of the feeder connector.

[0018] Participate in the Figure 2 As shown, the thrust ring 6 is evenly provided with a plurality of elastic barbs 601 for fixing the cable along the circumference; the elastic barbs 601 on the thrust ring 6 are brought into contact with the outer shell of the cable inserted into the feeder connector to limit the outer shell of the cable, thereby fixing the cable.

[0019] See attached Figure 1-3 As shown, a bushing 101 is also installed in the front shell 1; a plurality of washers 201 for fixing the thrust ring 6 are installed between the bushing 101 and the rear shell 2; a sealing ring 7 is installed between the front shell 1 and the rear shell 2 and in the rear shell 2; an insulating sleeve 8 is installed in the socket 5; and by installing the thrust ring 6 between washers 201 and washers 201 and between washers 201 and bushing 101, the installation of the thrust ring 6 is facilitated.

[0020] During the installation process of the present invention, first, the inner core of the cable of the feeder connector cable is stripped out to a length corresponding to the installation length, and then the end of the cable stripped out of the inner core is inserted into the jack in the feeder connector. At the same time, when the outer shell of the cable passes through the thrust ring 6 in the rear shell 2, the elastic barb 601 is squeezed outward, so that the elastic barb 601 is closely attached to the outer shell of the cable to limit the cable, thereby fixing the cable to the feeder connector. The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
