Description

Technical Field

[0001] This application relates to the technical field of radio communication, and particularly to a ferrule device for connecting a feeder pipe to a feeder pipe. Background Art

[0002] In antenna systems, microwave transmission, and wireless transmission and reception equipment. As an important component connecting a transmitter or receiver to an antenna, the feeder pipe is used to efficiently transmit high-frequency signals. The internal design of the feeder pipe includes a central conductor and an external shielding layer, with a certain medium between them, jointly forming a coaxial structure to guide the propagation of electromagnetic waves.

[0003] Specific connectors are usually required to be installed at both ends of the feeder pipe for connection to equipment or antennas. The ferrule device is a key component for connecting the feeder pipe and the equipment. It not only needs to ensure the stability of the electrical connection but also achieve good sealing to prevent environmental factors such as moisture or dust from affecting the signal quality.

[0004] Currently, most of the ferrules for feeder pipes on the market are equipped with a hole retaining ring inside the ferrule to tightly fasten the feeder line connected inside the ferrule. This results in a gap between the ferrule and the inner wall of the feeder pipe after the insertion is completed, and it is easy for dust to enter the feeder line during long-term use, thus affecting the feeder line. Summary of the Utility Model

[0005] In order to reduce the influence of dust on the feeder line connected to the ferrule, this application provides a ferrule device for connecting a feeder pipe to a feeder pipe.

[0006] The ferrule device for connecting a feeder pipe to a feeder pipe provided by this application adopts the following technical solution:

[0007] A ferrule device for connecting a feeder pipe to a feeder pipe includes a core body. Slots penetrating the side wall of the core body are inwardly provided at both ends of the core body, and a contact portion is provided at each end of the core body. The contact portion can be in contact with the inner wall of the feeder pipe when inserted into the feeder pipe and drive the side wall of the end of the core body to be in contact with the feeder line inside the core body.

[0008] By adopting the above technical solution, when connecting the feeder pipe, the end of the core body is inserted into the adjacent feeder pipe, and the feeder line is inserted into the core body, so that the feeder line is in contact with the inner wall of the core body. During the process of inserting the core body into the feeder pipe, the side wall of the contact portion at the end of the core body is in contact with the inner wall of the feeder pipe, thereby driving the side wall of the end of the core body to move towards each other and be in contact with the internal feeder line, thus reducing the gap between the inner wall of the core body and the feeder line, and further reducing the occurrence of dust entering the feeder line.

[0009] Optionally, the abutting portion is arranged as an arc-shaped side wall, and the arc-shaped side wall of the abutting portion is bent away from the center of the core body gradually from the outer wall of the core body to the inner wall of the core body.

[0010] By adopting the above technical solution, by arranging the abutting portion as an arc-shaped side wall, after the end of the core body is inserted into the inner part of the feeder tube, since the arc-shaped side wall of the end of the core body abuts against the inner wall of the feeder tube, the side wall of the end of the core body is driven to move towards the direction of approaching each other, thereby reducing the size of the slot, achieving the reduction of dust entering the inner feeder line of the core body through the slot while facilitating the process of inserting the end of the core body into the inner part of the feeder tube.

[0011] Optionally, the included angle between the side of the abutting portion close to the outer wall of the ferrule and the extended surface of the outer wall is set to 0.56 degrees.

[0012] By adopting the above technical solution, by setting the curvature of the side wall of the abutting portion to 0.56 degrees, it is possible to achieve a tight fit between the core body and the feeder tube while reducing signal leakage.

[0013] Optionally, the slots opened at both ends of the core body are arranged staggeredly with each other.

[0014] By adopting the above technical solution, by arranging the slots opened at both ends of the core body staggeredly, the phenomenon that the side wall of the core body between the two slots is short due to the opposite arrangement of the slots and is prone to breakage during actual use is reduced.

[0015] Optionally, a limiting member is provided at the middle position of the outer wall of the core body, and the limiting member is used to limit the position of each end of the core body inserted into the inner part of the feeder tube.

[0016] By adopting the above technical solution, by providing the limiting member, when the end of the core body is inserted into the inner part of the feeder tube, the phenomenon that the contact part between the core body and the feeder tube is less when connecting another feeder tube due to the difficulty for the staff to control the size of the end of the core body inserted into the inner part of the feeder tube, resulting in unstable connection between the two simultaneously connected feeder tubes, is reduced.

[0017] Optionally, the limiting member is arranged as a retaining ring, and the retaining ring is fixedly sleeved on the outside of the core body.

[0018] By adopting the above technical solution, by arranging the limiting member as a retaining ring, during actual use, by inserting the core body into the inner part of the feeder tube and making the end side wall of the feeder tube abut against the side wall of the retaining ring, the connection position between the feeder tube and the core body can be known, thereby facilitating the process for the staff to uniformly connect two feeder tubes with the same core body.

[0019] Optionally, a high-tin bronze coating is fixedly connected to the outer wall of the core body.

[0020] By adopting the above technical solution, by connecting a high-tin bronze coating to the outer wall of the core body, the hardness and strength of the outer wall of the core body can be increased, and due to the lubricity and corrosion resistance of the high-tin bronze coating itself, the phenomenon that the core body is difficult to continue to be used due to wear or corrosion during long-term use is reduced.

[0021] Optionally, a silver-plated coating is fixedly connected to the inner wall of the core body.

[0022] By adopting the above technical solution, by setting the silver-plated coating, the phenomenon that the inner wall of the core body is corroded and damaged during use is reduced, and due to the presence of silver, the signal loss during signal transmission is reduced.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By abutting the feeder against the inner wall of the core body and setting the side wall of the abutting portion to be arc-shaped, when connecting the feeder pipe, the inner wall of the core body can be fully abutted against the feeder, and the size of the slot can be reduced, thereby reducing the phenomenon that external dust enters the feeder and affects the performance of the feeder.

[0025] 2. By setting the retaining ring, during actual use, the phenomenon that due to the difficulty for the staff to control the size of the core body inserted into the feeder pipe, the connection between the two feeder pipes and the core body is uneven, and further the feeder pipe falls off during use is reduced.

[0026] 3. By setting the high-tin bronze coating and the silver-plated coating, the corrosion resistance of the core body can be increased, and the signal loss caused during signal transmission is reduced. Description of the Drawings

[0027] Figure 1 is the overall structural schematic diagram of the embodiment of the present application.

[0028] Description of the reference numerals: 1, core body; 11, slot; 12, abutting portion; 2, limiting member; 21, retaining ring. Detailed Embodiment

[0029] The following further elaborates on the present application in conjunction with the attached Figure 1 for further detailed description.

[0030] The embodiment of the present application discloses an insert core device for connecting a feeder pipe to a feeder pipe. Refer to Figure 1, including a cylindrical core 1, with a cylindrical through-hole provided at the middle position inside the core 1. A plurality of slots 11 are provided at each end of the core 1 in the direction towards the other end of the core 1. Each slot 11 penetrates through the side wall of the core 1 to communicate the inside of the core 1 with the outside. The plurality of slots 11 provided at each end of the core 1 are evenly and spaced around the side wall of the core 1, and the slots 11 provided at both ends of the core 1 are staggered with each other.

[0031] An abutting portion 12 is provided at each end of the core 1, and when each abutting portion 12 is inserted into the inside of the feed pipe, it can abut against the inner wall of the feed pipe and squeeze the side wall of the end of the core 1, thereby reducing the size of the slot 11 so that the side wall of the end of the core 1 contracts inwards and abuts against the feeder inserted into the inside of the core 1.

[0032] During actual use, the end of the core 1 is inserted into the inside of the feed pipe, and the feeder is inserted into the cylindrical cavity of the core 1 so that the inner wall of the core 1 abuts against the feeder. After the end of the core 1 is inserted into the inside of the feed pipe, the abutting portion 12 at the end of the core 1 abuts against the inner wall of the feed pipe, and then the side walls of the abutting portion 12 at the end of the core 1 move towards each other, reducing the size of the slot 11 while making the side wall of the end of the core 1 abut against the inner feeder, thereby realizing the connection process of the feed pipe and the feeder.

[0033] Since the inner wall of the core 1 directly abuts against the feeder, and when the core 1 is inserted into the inside of the feed pipe, the side walls of the end of the core 1 move towards each other to reduce the size of the slot 11, so that the gap on the side wall of the feed pipe is reduced, and the inner wall of the feed pipe is in close contact with the feeder, thereby realizing full protection of the feeder inside the core 1.

[0034] The abutting portion 12 is provided with an arc-shaped side wall, and the arc-shaped side walls of the abutting portion 12 are bent gradually away from the center of the core 1 from the side close to the outer wall of the core 1 towards the side close to the inner wall of the core 1.

[0035] The included angle between the side wall of the core 1 at the abutting portion 12 close to the outer wall of the connected core 1 and the extension line of the outer wall of the core 1 is set to 0.56 degrees.

[0036] By setting the abutting portion 12 of the core 1 to be circular arc-shaped, the process of inserting the end of the core 1 into the inside of the feed pipe is facilitated.

[0037] A limiting member 2 is provided at the middle position of the core 1, and the limiting member 2 is used to limit the size of each end of the core 1 inserted into the inside of the feed pipe.

[0038] By setting the position-limiting member 2, it is convenient for the staff to control the size of the core body 1 inserted into the feeder tube, so that the core body 1 can be evenly connected to the two feeder tubes, and the connection between the core body 1 and the two feeder tubes can be more stable.

[0039] The position-limiting member 2 is set as a retaining ring 21. The retaining ring 21 is fixedly sleeved at the middle position of the outer wall of the core body 1, and the center line of the retaining ring 21 coincides with the center line of the core body 1. On one side of each slot 11 away from the end of the core body 1, it is opened to the retaining ring 21 and penetrates through the side wall of the retaining ring 21.

[0040] When connecting the core body 1 to the feeder tube, insert the end of the core body 1 into the adjacent feeder tube and make the side wall of the retaining ring 21 abut against the end side wall of the feeder tube, so as to know whether the parts of the core body 1 inserted into the two feeder tubes are uniform.

[0041] A high-tin bronze coating is fixedly connected to the outer wall of the core body 1.

[0042] By setting the high-tin bronze coating, the wear resistance, corrosion resistance and thermal stability of the core body 1 can be improved, thereby increasing the service life of the core body 1.

[0043] A silver-plated coating is fixedly connected to the inner wall of the core body 1.

[0044] By setting the silver-plated coating, the signal transmission loss can be effectively reduced, and at the same time, the corrosion resistance of the core body 1 can be increased.

[0045] The implementation principle of an insert core device for connecting feeder tubes to feeder tubes in an embodiment of the present application is as follows: during actual use, after the core body 1 is inserted into the feeder tube, the side wall of the abutting portion 12 at the end of the core body 1 abuts against the inner wall of the feeder tube, so that the side wall of the end of the core body 1 moves towards the direction of approaching each other, so that the inner wall of the core body 1 can abut against the feeder line inside the core body 1, and the size of the slot 11 opened on the side wall of the core body 1 is reduced.

[0046] And during the process of inserting the core body into the feeder tube, by making the end side wall of the feeder tube abut against the retaining ring, the length of the core body inserted into the feeder tube can be controlled, and then the core body can be evenly connected to the two feeder tubes.

[0047] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
