Description

Technical Field

[0001] The utility model belongs to the field of radio frequency adapters, and in particular relates to a cluster radio frequency adapter. Background Art

[0002] As the accuracy requirements for satellite navigation and positioning equipment continue to increase, the number of satellite navigation and positioning signal antennas installed in these devices will increase accordingly, and so will the number of signal transmission cables and corresponding plugs connected to them. When more signal transmission cables and corresponding plugs are installed in navigation and positioning equipment, it is necessary to add corresponding mounting holes and sealing devices to the equipment box where the navigation and positioning equipment is installed.

[0003] Figure 9 This is a partial view of the device case of the satellite navigation positioning device. The left side of the box panel 31 of the device case is the installation arrangement of the plug 33 in the prior art, and three mounting openings 32 are respectively provided thereon corresponding to the three plugs 33 in the device case. Accordingly, the three plugs 33 are respectively connected to the three adapters.

[0041] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0043] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, the terms "first," "second," etc. are used only to distinguish the descriptions and are not to be understood as indicating or implying relative importance.

[0044] like Figure 1 — Figure 9 As shown, a clustered RF adapter includes an RF component 1 and an adapter 2, and the two ends of the RF component 1 are connected to the adapter 2 and the coaxial cable respectively; the RF component 1 includes an RF body 11 and a plurality of RF conductor components 12 uniformly distributed along the circumference of the RF body 11, and correspondingly, the adapter 2 includes an adapter body 21 that cooperates with the RF body 11 and an adapter conductor component 22 that cooperates with the RF conductor component 12; one end of the adapter conductor component 22 is plugged into and connected to one end of the RF conductor component 12, and the other end thereof is plugged into and connected to the plug 33 of the device case 3; the other end of the RF conductor component 12 is connected to the inner conductor of the coaxial cable (not shown in the figure). The adapter 2 that integrates RF signals of multiple channels only uses one adapter 2 to connect the device to the external RF signal, and the antenna and the adapter 2 are connected through the RF component 1. The adoption of this technical measure reduces the number of operations performed by the operator during installation and reduces the number of installation openings 32 for installing the adapter 2 on the device case 3. Specifically, as Figure 7As shown, the right side of the cabinet panel 31 of the device cabinet 3 is a new cabinet panel. This new cabinet panel only needs to be provided with a single mounting opening 32 that mates with the plug mating end 24 of the adapter 2. This effectively reduces the number of mounting openings 32 required for the clustered RF adapter in the device cabinet 3, thereby improving the reliability of the navigation and positioning device. This technical measure has the advantages of fast assembly, high installation efficiency, and improved reliability of the navigation and positioning device.

[0045] like Figure 1 — Figure 8 As shown, the RF body 11 and the adapter body 21 of the RF component 1 and the adapter 2 are cylindrical. The RF component 1 and the adapter 2 are coaxial and can be detachably connected.

[0046] like Figure 1 、 Figure 5 — Figure 8 As shown, the adapter body 21 is evenly distributed along the circumference with adapter conductor mounting holes 211 for mounting the adapter conductor assembly 22, and the adapter conductor assembly 22 is interference-connected with the adapter conductor mounting holes 211.

[0047] Specifically, the adapter body 21 is cylindrical and has multiple adapter conductor mounting holes 211 axially and evenly distributed around the circumference. In this embodiment, there are three adapter conductor mounting holes 211, corresponding to three adapter conductor assemblies 22. In actual use, the number of adapter conductor mounting holes 211 and adapter conductor assemblies 22 can be increased or decreased based on actual needs.

[0048] An annular protrusion 25 is provided on the outer side of the middle part of the adapter body 21, and the two sides of the annular protrusion 25 are the device case plug mating end 24 and the RF mating end 23 respectively. A first nut 28 is threadedly connected to the outer side of the plug mating end 24, and an internal tooth washer 27 is provided between the first nut 28 and the annular protrusion 25. A second annular groove 251 is provided on the side of the annular protrusion 25 facing the plug mating end 24 of the device case, and a compression seal ring 26 is provided in the second annular groove 251. When the adapter 2 is connected to the plug 33 in the device case 3; after the end of the plug mating end 24 extends into the case panel 31 through the mounting opening 32, the internal tooth washer 27 is compressed by the first nut 28 on the inner side of the case panel 31, so that the adapter 2 is fixed on the case panel 31; and the external waterproof function is achieved by the compression seal ring 26 on the outer side of the case panel 31.

[0049] like Figure 1 、 Figure 5 、 Figure 6As shown, one end of the adapter conductor assembly 22 is an MCX inner core, and the other end is an SMP inner core, and the MCX inner core is coaxially connected to the SMP inner core; the SMP inner core is used to connect to the RF assembly 1, and the MCX inner core is used to be plugged and connected to the plug 33 in the equipment box 3.

[0050] The MCX core includes a quick-insert housing 221, a first inner conductor 222, and a first insulator 223 that is sleeved outside the first conductor and disposed within the quick-insert housing 221. The SMP core includes a tolerance housing 225, a second inner conductor 224, and a second insulator 226 that is sleeved outside the second conductor and disposed within the tolerance housing 225. One end of the second inner conductor 224 is fixedly connected to the first inner conductor 222, and the other end is disposed within the tolerance housing 225. Correspondingly, the adapter conductor mounting hole 211 includes a quick-insert main body section, a second inner conductor section, and a tolerance main body section. The second inner conductor 224 has a connecting groove at its end facing the quick-insert housing 221, and a connecting section that matches the connecting groove at its end facing the tolerance housing 225. After the connecting section is inserted into the connecting groove, it is connected by welding. This technical measure, using an SMP core with axial and radial floating tolerances, can reduce the impact of assembly and part tolerances on product performance when mated with the RF component 1. Therefore, the connection between the MCX inner core and the SMP inner core of the adapter conductor assembly 22 is made more stable.

[0051] like Figure 1 — Figure 3 As shown, the RF body 11 is provided with multiple circumferentially evenly distributed RF conductor mounting holes along the axial direction. These holes are used to mount the RF conductor assemblies 12. The RF conductor assemblies 12 and the holes form an interference fit. In actual use, the number of RF conductor assemblies 12 and the number of adapter conductor assemblies 22 are the same, and the number of RF conductor mounting holes and the number of adapter conductor mounting holes 211 are the same. The number of RF conductor assemblies 12 and adapter conductor assemblies 22 is generally three or more.

[0052] Specifically, the RF body 11 is cylindrical, with two connecting ends extending outward from both ends, namely a cable connecting end 112 and an adapter connecting end 111. The cable connecting end 112 is provided with an internal thread, which is threadedly connected to the rear nut 14.

[0053] like Figure 4As shown, screw holes are provided between the RF conductor mounting holes of the cable connection end 112 of the RF body 11, and screws 15 are installed in the screw holes. After the screws 15 are installed, the heads of the screws 15 press against the elbow shoulder 122 of the RF conductor assembly 12. Specifically, the RF conductor assembly 12 includes a wire bonding housing 121, a contact head 124, a third inner conductor 126, a fourth insulator 125, and a fifth insulator 127. The contact head 124 is provided in the wire bonding housing 121, facing one end of the adapter 2. One end of the third inner conductor 126 is provided in the contact head 124, and the other end is provided in the wire bonding housing 121. The fourth insulator 125 and the fifth insulator 127 are respectively provided at both ends of the third inner conductor 126. The fifth insulator 127 is provided in the contact head 124, and the fourth insulator 125 is provided in the other end of the wire bonding housing 121 away from the contact head 124. The elbow shoulder 122 with an annular protrusion 25 is provided on the outer side of the middle portion of the wire bonding housing 121. The wire housing 121 is provided with a first sealing ring 123 on one side of the elbow shoulder 122. The elbow shoulder 122 of the wire housing 121 is pressed against the head of the screw 15, achieving direct fixation. This facilitates the removal and replacement of the RF core without the need for opening holes or additional parts such as pressure plates and elastic claws.

[0054] like Figure 1 — Figure 6 As shown, the RF mating end 23 of the adapter body 21 is provided with a threaded section 231 , and the adapter connection end 111 of the RF body 11 is provided with a connecting nut 13 that cooperates with the threaded section 231 , and the adapter body 21 and the RF body 11 are threadedly connected.

[0055] Specifically, an annular connecting platform 113 is provided on the outer side of the adapter connecting end 111 of the RF body 11, and an annular connecting platform 113 is provided with an annular retaining groove 114; the inner diameter of the RF mating end 23 is larger than the outer diameter of the adapter connecting end 111 and smaller than the inner diameter of the connecting nut 13. A movable gap for the RF mating end 23 to be inserted is formed between the inner side of the connecting nut 13 and the outer side of the adapter connecting end 111. A first annular groove 115 is provided on the inner side of the connecting nut 13 corresponding to the annular retaining groove 114, and a retaining ring 16 is provided between the annular retaining groove 114 and the first annular groove 115. The connecting nut 13 is movably connected to the outer side of the adapter connecting end 111 through the retaining ring 16. The RF mating end 23 of the adapter body 21 is provided with a threaded section 231 that cooperates with the connecting nut 13. After the front end of the RF mating end 23 is inserted into the movable gap between the inner side of the connecting nut 13 and the outer side of the adapter connecting end 111, the connecting nut 13 is rotated to thread it into the threaded section 231, thereby threading the adapter body 21 and the RF body 11 together.

[0056] The adapter connection end 111 of the RF body 11 is provided with a waterproof sealing ring 17 . One side of the waterproof sealing ring 17 abuts against the annular connection platform 113 and faces the adapter connection end 111 .

[0057] like Figure 1 、 Figure 3 、 Figure 6 As shown, the outer side of the adapter connection end 111 of the RF body 11 has an axially defined groove 115. The inner diameter of the RF mating end 23 of the adapter body 21 is larger than the outer diameter of the adapter connection end 111 of the RF body 11. The inner side of the RF mating end 23 of the adapter body 21 is provided with a protruding key 29 that mates with the groove 115. When the adapter connection end 111 of the RF body 11 and the RF mating end 23 of the adapter body 21 mate with each other, the protruding key 29 mates with the groove 115. This technical measure has the advantage of preventing mis-insertion during insertion.

[0058] After the RF component 1 is assembled, the cable connection end 112 of the RF component 1 is added with an integral cable protective cover by low-pressure injection molding, thereby increasing the reliability of the RF component 1 .
