Description

Technical Field

[0001] The utility model belongs to the technical field of radio frequency coaxial connectors, and in particular relates to an outer conductor contact piece of a radio frequency coaxial connector. Background Art

[0002] RF coaxial connectors are mainly used as components for electrically connecting or separating transmission lines, and can effectively transmit RF and microwave signals.

[0003] Currently, a Chinese utility model with publication number CN209448166U discloses an elastic outer conductor for a radio frequency coaxial connector, comprising an elastic portion and a clamping portion. The elastic portion comprises a plurality of elastic clips distributed in a divergent manner at the upper end of the clamping portion. All of the elastic clips enclose a cylindrical shape, with the interior of the cylindrical shape being the inner side and the exterior being the outer side. Each of the elastic clips comprises a first arc piece that protrudes obliquely downward and outward, a second arc piece that is recessed obliquely downward and inward, and a contact. The first arc piece is connected to the clamping portion, and the second arc piece is connected to the first arc piece. The first and second arc pieces are provided with connecting grooves. This utility model utilizes the first and second arc pieces to greatly improve the elasticity of the elastic outer conductor.

[0004] During the insertion process of the outer conductor contacts of existing RF coaxial connectors, the contact surface lacks protection, resulting in poor connection reliability. External impacts can affect the stability of the insertion and easily cause the outer conductor contacts of the RF coaxial connector to fall off. Furthermore, since the angle of the contacts of the RF coaxial connector cannot be adjusted, the RF coaxial connector cannot be adjusted according to actual connection requirements. When inserting outer conductor contacts at multiple different angles, different tooling is required, resulting in poor versatility. Utility Model Content

[0005] The purpose of the utility model is to provide an RF coaxial connector outer conductor contact, which has the advantages of improving the stability of the connection of the RF coaxial connector outer conductor contact and facilitating the outer conductor contact to be rotated and adjusted to a variety of different angles for connection.

[0006] The above technical objectives of the present utility model are achieved through the following technical solutions: an outer conductor contact of a radio frequency coaxial connector, comprising a connector housing, one end of the connector housing being fixedly connected to the outer conductor contact, both sides of the top and bottom of the outer conductor contact being provided with rack rods that are slidably connected to the connector housing, a fixed push plate being welded to the end of the outer conductor contact away from the interior of the connector housing, a threaded groove being provided on the surface of the outer conductor contact, a sliding sleeve being slidably sleeved on the end of the surface of the connector housing close to the outer conductor contact, tooth grooves being provided on both sides of the inner surface of the sliding sleeve, and a disc gear being rotatably connected to the interior of the connector housing and meshing with the rack rod and the tooth groove respectively.

[0007] Using the above technical solution, the rack rod is driven to slide toward the interior of the connector housing by pushing the fixed push plate, driving the rack rod and the tooth groove to engage with the disc gear, causing the sliding sleeve to slide forward to cover the surface of the outer conductor contact for protection. This improves the stability of the connection of the outer conductor contact of the RF coaxial connector and prevents it from falling off due to collisions. By sliding the rotating ring inside the rear shell, the connector housing can be adjusted axially. At the same time, by rotating one end of the telescopic rod inside the connector housing, the connector housing can be adjusted left and right. This allows for connections at various angles, improving the practicality of the RF coaxial connector.

[0008] The utility model is further configured as follows: a rear shell is provided at the end of the connector housing away from the outer conductor contact piece, a rotating ring is slidably connected to the interior of the rear shell, two telescopic rods fixedly connected to the rotating ring are symmetrically provided on the side of the rear shell close to the connector housing, an annular sliding groove is provided on the side of the rear shell close to the outer conductor contact piece that is slidably connected to the telescopic rod, and the end of the telescopic rod away from the rear shell is fixedly connected to a rotating rod rotatably connected to the connector housing.

[0009] By adopting the above technical solution, connections at various angles can be made, thereby improving the practicality of the RF coaxial connector.

[0010] The utility model is further configured as follows: a slider slidably connected to the connector housing is welded on the side of the rack rod away from the fixed push plate, and a spring fixedly connected to the connector housing is installed on the side of the slider away from the rack rod.

[0011] By adopting the above technical solution, the rebound force of the spring is used to push the slider to slide, so that the rack rod can be automatically ejected from the inside of the connector housing for reset after the connector housing is separated.

[0012] The utility model is further configured as follows: a connecting wire is fixedly connected to the inside of the connector housing and is slidably connected to the rear shell sleeve; an end of the connecting wire close to the outer conductor contact piece is electrically connected to a metal conductor core clamped to the connector housing.

[0013] By adopting the above technical solution, the outer conductor contact piece is connected to the plug, so that the connected plug can contact the metal conductor core, thereby achieving power connection.

[0014] The utility model is further configured as follows: sealing rings that are slidably sleeved with the connector housing are bonded to both sides of the inner surface of the sliding sleeve.

[0015] By adopting the above technical solution, the sealing performance of both sides of the interior of the sliding sleeve is improved, thereby preventing moisture from penetrating therein.

[0016] The utility model is further configured as follows: an anti-slip groove is provided on the end of the connector shell surface away from the disc gear.

[0017] By adopting the above technical solution, the surface friction of the connector shell is improved, which facilitates quick connection.

[0018] The utility model is further configured as follows: magnet blocks that are magnetically attracted to each other are clamped between the connector shell and the rear shell.

[0019] By adopting the above technical solution, the rear shell can be adsorbed and fixed to one side of the connector housing by utilizing the magnetic force of the magnet block, thereby fixing and limiting the connector housing when angle adjustment is not required.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. Pushing the fixed push plate drives the rack rod to slide toward the inside of the connector housing, driving the rack rod and the tooth groove to engage with the disc gear, so that the sliding sleeve slides forward to cover the surface of the outer conductor contact for protection. This improves the stability of the connection of the outer conductor contact of the RF coaxial connector and prevents it from falling off due to collision.

[0022] 2. The connector housing can be adjusted axially by sliding a rotating ring inside the rear housing. Simultaneously, the connector housing can be adjusted left and right by rotating one end of the telescopic rod inside the housing. This allows for connections at various angles, improving the practicality of RF coaxial connectors. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] refer to Figure 1 、 Figure 2 An outer conductor contact of a radio frequency coaxial connector includes a connector housing 1, one end of which is fixedly connected to an outer conductor contact 2, and both the top and bottom sides of the outer conductor contact 2 are provided with rack rods 3 that are slidably connected to the connector housing 1. A fixed push plate 18 is welded to the end of the outer conductor contact 2 away from the interior of the connector housing 1, and a threaded groove 19 is provided on the surface of the outer conductor contact 2. A sliding sleeve 7 is slidably sleeved on the end of the surface of the connector housing 1 close to the outer conductor contact 2, and tooth grooves 8 are provided on both sides of the inner surface of the sliding sleeve 7. A disc gear 6 is rotatably connected to the interior of the connector housing 1 and meshes with the rack rod 3 and the tooth groove 8 respectively. By pushing the fixed push plate 18, the rack rod 3 is driven to slide toward the interior of the connector housing 1, driving the rack rod 3 and the tooth groove 8 to mesh with the disc gear 6, so that the sliding sleeve 7 slides forward to cover the surface of the outer conductor contact 2 for protection. This improves the stability of the connection of the outer conductor contact of the radio frequency coaxial connector and prevents it from falling off due to collision.

[0030] refer to Figure 2 A slider 4 is welded to the side of the rack rod 3 that is away from the fixed push plate 18 and is slidably connected to the connector housing 1. A spring 5 is mounted on the side of the slider 4 that is away from the rack rod 3 and is fixedly connected to the connector housing 1. The rebound force of the spring 5 pushes the slider 4 to slide, so that the rack rod 3 can be automatically ejected from the interior of the connector housing 1 and reset after the connector housing 1 is separated.

[0031] refer to Figure 2 , both sides of the inner surface of the sliding sleeve 7 are bonded with sealing rings 16 that are slidably sleeved with the connector housing 1. The sealing performance of both sides of the sliding sleeve 7 is improved to prevent moisture from penetrating therein.

[0032] refer to Figure 1 The end of the connector housing 1 away from the disc gear 6 is provided with anti-slip grooves to improve the surface friction of the connector housing 1 and facilitate quick connection.

[0033] Operational Overview: Connector housing 1 is secured by threaded engagement with the thread groove 19 on the surface of the outer conductor contact 2. As threaded engagement occurs, connector housing 1 moves forward, allowing the plug connected to connector housing 1 to push against the fixed push plate 18, which in turn causes rack rod 3 to slide toward the interior of connector housing 1. Rack rod 3 then engages with disc gear 6, rotating it and engaging with tooth groove 8. This causes sliding sleeve 7 to slide across the surface of connector housing 1 in the direction away from rack rod 3, covering and protecting the surface of outer conductor contact 2.

[0034] Example 2:

[0035] refer to Figure 1 、 Figure 2 、 Figure 3 , an RF coaxial connector outer conductor contact, a rear shell 9 is provided at the end of the connector housing 1 away from the outer conductor contact 2, a rotating ring 10 is slidably connected inside the rear shell 9, two telescopic rods 11 fixedly connected to the rotating ring 10 are symmetrically provided on the side of the rear shell 9 close to the connector housing 1, an annular groove 13 is provided on the side of the rear shell 9 close to the outer conductor contact 2, and a rotating rod 12 is fixedly connected to the connector housing 1 at the end of the telescopic rod 11 away from the rear shell 9. By sliding the rotating ring 10 inside the rear shell 9, the connector housing 1 can be adjusted in axial angle. At the same time, by rotating one end of the telescopic rod 11 inside the connector housing 1, the connector housing 1 can be adjusted in left and right angles. In this way, connections at various angles can be made, thereby improving the practicality of the RF coaxial connector.

[0036] refer to Figure 2 、 Figure 3 A connecting wire 14 is fixedly connected to the interior of the connector housing 1 and slides through the rear housing 9. The end of the connecting wire 14, which is closest to the outer conductor contact 2, is electrically connected to a metal conductor 15 that is snap-fitted to the connector housing 1. By connecting the outer conductor contact 2 to a plug, the connected plug can contact the metal conductor 15, thereby establishing power communication.

[0037] refer to Figure 2 A magnet block 17 is connected between the connector housing 1 and the rear housing 9. The magnet block 17 can be used to fix the rear housing 9 to one side of the connector housing 1, thereby fixing the connector housing 1 when angle adjustment is not required.

[0038] Briefly describe the process: By sliding the rotating ring 10 inside the rear housing 9, the connector housing 1 can be rotated axially to one side of the rear housing 9. Then, by pulling the connector housing 1 outward, the telescopic rod 11 extends, creating a gap between the connector housing 1 and the rear housing 9. At this point, the connector housing 1 is moved, and the rotating rod 12 is used to rotate one end of the telescopic rod 11 inside the connector housing 1, allowing the outer conductor contact 2 to rotate left and right to connect.
