Description

Technical Field

[0001] This application relates to the technical field of communication equipment, and in particular to a line protection card and a phase shifter. Background Technology

[0002] The phase shifter is one of the key components of a base station antenna. It adjusts the electrical downtilt angle of the antenna to enable signal transmission. A phase shifter typically consists of a phase shifting network, a dielectric substrate, a cavity, push-pull rods, soldered cables, and a fixing structure, which includes cable guards and a phase shifter mounting bracket.

[0003] Typically, during the assembly of a phase shifter, cable clamps are used to secure the welded cables to protect the solder joints from damage. However, during cable welding, heat is transferred to the cavity, which can easily cause the outer insulation layer of the cable, which is in close contact with the cavity, to be burned by the high temperature. This can prevent the cable from working properly and affect the intermodulation and other performance indicators of the phase shifter. Utility Model Content

[0004] Therefore, it is necessary to provide a cable protection clip and a phase shifter to address the problem that cables are easily damaged by high temperatures in traditional technologies, which affects the intermodulation performance of phase shifters.

[0005] A first aspect of this application provides a cable protection clip, comprising:

[0006] Carrier plate;

[0007] A cable clamp, disposed on the carrier plate, is used to clamp and position the cable; and

[0008] A baffle plate is connected to one end of the carrier plate along a first direction of the cable guard. The baffle plate is used to block heat from being conducted from the cavity to the cable.

[0009] The cable protection clip in this solution is used when installing cables onto the cavity of a phase shifter. In use, the clip is aligned and inserted into the mounting slot of the cavity, and then the cable is clipped into the pre-installed clamp on the carrier plate. At this point, the baffle plate is positioned precisely between the cable and the cavity, effectively separating the cable from the cavity. Furthermore, when welding the cable, the heat conducted to the cavity is blocked by the baffle plate, preventing heat from being transferred from the cavity to the cable. This avoids the cable's outer insulation layer being damaged by high temperatures, ensuring the cable functions properly and preventing any impact on the phase shifter's intermodulation and other performance indicators.

[0010] The technical solution of this application will be further described below:

[0011] In one embodiment, the baffle includes a baffle plate and a support rib, the baffle plate being connected to the carrier plate, and the support rib being disposed on the baffle plate and located on the same side of the cable guard as the cable clamp.

[0012] In one embodiment, the side of the carrier plate away from the partition plate is provided with a first abutting portion, which is used to abut and position itself against the first groove sidewall of the mounting groove on the cavity.

[0013] In one embodiment, the side of the baffle away from the carrier plate is provided with a second abutment portion, which is used to abut and position itself against the second groove sidewall of the mounting groove on the cavity.

[0014] In one embodiment, the cable clamp includes a cable holder with a recessed cable groove for clamping a cable.

[0015] In one embodiment, the cable clamp further includes a locking element, and the cable holder has a locking portion. The locking element is used to lock into the locking portion, so that the locking element covers the opening of the cable slot to constrain the cable within the cable slot.

[0016] In one embodiment, the locking component includes an elastic part, a main body part, and a hook part. One side of the elastic part is connected to the locking wire seat, and the other side of the elastic part is connected to one side of the main body part. The other side of the main body part is connected to the hook part, and the hook part can engage or disengage with the locking part.

[0017] In one embodiment, the cable guard further includes a clip connected to the other end of the carrier plate along a first direction of the cable guard, the clip being used to engage with a slot provided on the cavity.

[0018] In one embodiment, the cable guard further includes a first limiting body and a second limiting body. The first limiting body is connected to one end of the carrier plate along a second direction of the cable guard, and the second limiting body is connected to the other end of the carrier plate along the second direction of the cable guard. The first limiting body is used to engage with the first outer side wall of the cavity, and the second limiting body is used to engage with the second outer side wall of the cavity.

[0019] A second aspect of this application also proposes a phase shifter comprising:

[0020] The cavity is provided with a mounting groove;

[0021] The cable guard as described above is disposed within the mounting slot; and

[0022] The cable is installed in the cable guard. Attached Figure Description

[0040] See Figure 1 and Figure 2 This application presents a cable protection clip 10 as an embodiment of the present application. Specifically, it is a mounting component that can install and position the cable 30 on the cavity 20 of the phase shifter 100 to ensure the connection reliability and safety of the cable 30.

[0041] For example, the cable guard 10 includes a carrier plate 11, a cable clamp 12, and a baffle plate 13.

[0042] Among them, the carrier plate 11 is the main component of the cable protection clip 10, which serves to load the integrated card clip 12 and the baffle plate 13.

[0043] For example, the carrier plate 11 can be any regular shape such as rectangle, circle, triangle or other irregular structure, and can be flexibly selected according to actual needs.

[0044] Please continue reading. Figure 4 The cable clamp 12 is disposed on the carrier plate 11 and is used to clamp and position the cable 30. That is, the cable clamp 12 achieves clamping and positioning of the cable 30 by assembling with the cable 30.

[0045] The cable clamp 12 can be integrally formed with the carrier plate 11 or it can be detachably assembled, depending on the needs. For example, in this application, the cable clamp 12 and the carrier plate 11 are an integral structure, which has high connection strength, good overall structure, and fewer parts, thereby helping to improve the installation efficiency of the cable protection clip 10.

[0046] When the cable clip 12 and the carrier plate 11 are connected in a detachable manner, they can be assembled using at least one of the following methods: screw connection, clip connection, magnetic connection, adhesive connection, etc.

[0047] Please continue reading. Figure 1 and Figure 2 Furthermore, more than one cable clamp 12 can be provided. For example, in this application, two cable clamps 12 are integrated and installed on a single carrier board 11. That is, a cable protection clip 10 includes two cable clamps 12, and the two cable clamps 12 respectively clamp and position at least one cable 30.

[0048] To facilitate the installation of cable 30, two cable clamps 12 are arranged on the same side of the carrier plate 11, and are arranged side by side at intervals along the second direction of the cable guard 10 on the carrier plate 11.

[0049] It should be noted that the second direction specifically refers to Figure 1 Arrow S2 in the diagram points to...

[0050] The baffle plate 13 is connected to one end of the carrier plate 11 along the first direction of the cable guard 10. The baffle plate 13 is used to block the cable 30 and the cavity 20 to prevent heat from being conducted from the cavity 20 to the cable 30.

[0051] Understandably, the baffle 13 is made of high-temperature resistant heat-insulating materials, such as polyimide (PI), resin, fiber, etc. Alternatively, the entire cable protection clip 10 can be made of high-temperature resistant heat-insulating materials. The choice can be made flexibly according to actual needs.

[0052] Furthermore, the baffle 13 can be integrally formed with the carrier plate 11, or it can be detachably assembled.

[0053] It should be noted that the first direction specifically refers to Figure 1 Arrow S1 in the diagram points to...

[0054] Please continue reading. Figures 3 to 5In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: The cable guard 10 of this solution is used when the cable 30 is installed on the cavity 20 of the phase shifter 100. In use, the cable guard 10 is aligned and inserted into the mounting groove 21 of the cavity 20, and then the cable 30 is clamped into the cable clamp 12 preset on the carrier plate 11. At this time, the baffle plate 13 is located between the cable 30 and the cavity 20, which realizes the separation of the cable 30 from the cavity 20. On this basis, when the cable 30 is welded, the heat conducted to the cavity 20 by the welding is blocked by the baffle plate 13, so that the heat cannot be conducted from the cavity 20 to the cable 30. This can prevent the insulation layer of the cable 30 from being burned by high temperature, ensure that the cable 30 cannot work normally, and avoid affecting the intermodulation and other performance indicators of the phase shifter 100.

[0055] In this application, the wire protection clip 10 is used to be installed into the pre-set mounting groove 21 on the cavity 20 of the phase shifter 100. On the one hand, by forming a snap-fit ​​relationship with the side wall of the mounting groove 21 and the outer wall of the cavity 20, the installation firmness of the wire protection clip 10 is improved. On the other hand, the wire protection clip 10 is located in the groove cavity of the mounting groove 21, which avoids protruding from the outer surface of the cavity 20, thereby reducing the installation space occupied, making the phase shifter 100 smaller and facilitating miniaturization design.

[0056] Please continue reading. Figures 1 to 2 In an optional embodiment, the baffle 13 includes a baffle plate 131 and a support rib 132. The baffle plate 131 is connected to the carrier plate 11, and the support rib 132 is disposed on the baffle plate 131 and is on the same side of the cable clamp 12 as the cable protection clip 10. After the cable protection clip 10 is installed into the mounting groove 21, the cable 30 is then clipped onto the cable clamp 12. The baffle plate 131 is positioned between the cable 30 and the cavity 20, thereby blocking heat from being conducted from the cavity 20 to the cable 30 and preventing the outer insulation layer of the cable 30 from being burned.

[0057] Considering that the cable 30 is installed close to the cavity 20, meaning the gap between the cable 30 and the outer wall of the cavity 20 is small, the baffle 131 also adopts a thin sheet structure to accommodate the installation requirements of the narrow gap. However, this sacrifices the structural strength of the baffle 131, which is detrimental to the stable and reliable installation of the cable protection clip 10. Therefore, by providing support ribs 132 on the baffle 131, the structural strength of the baffle 131 can be improved, compensating for the strength loss caused by its size limitations.

[0058] In this application, when two cable clips 12 are simultaneously installed on the carrier plate 11, the support rib 132 is arranged in the middle of the baffle 131 and between the two cable clips 12. At this time, the two cable clips 12 are arranged symmetrically with respect to the structural center line of the support rib 132, which can improve the installation versatility of the cable guard 10 and enhance its aesthetics.

[0059] In another embodiment, the cable protection clip 10 further includes a clip 14, which is connected to the other end of the carrier plate 11 along the first direction of the cable protection clip 10. The clip 14 is used to engage with the slot 22 provided on the cavity 20. That is, when installing the cable protection clip 10, the clip 14 needs to be aligned and inserted laterally into the slot 22 to achieve a snap-fit ​​fixation and improve the stability of the cable protection clip 10 installation.

[0060] Please continue reading. Figures 6 to 7 It should be noted that, in order to facilitate the installation of the cable protection clip 10 into the mounting slot 21 of the cavity 20, the size of the mounting slot 21 is designed to be slightly larger than the size of the cable protection clip 10. Furthermore, the insertion slot of the card slot 22 on the cavity 20 is set towards the cavity of the mounting slot 21. Therefore, when installing the cable protection clip 10, the end of the card strip 14 needs to be aligned with the insertion slot so that the card strip 14 can be pushed laterally into the card slot 22. However, at this time, the baffle 13 will remain outside the mounting slot 21 and be interfered with by the outer wall of the cavity 20 near the mounting slot 21.

[0061] At this time, because the baffle 131 is a thin sheet structure, it has a certain elastic deformation capability. As the clip 14 is inserted into the slot 22, the baffle 131 can smoothly pass over the outer wall of the cavity 20 through bending deformation, and then can be smoothly installed into the mounting slot 21 and recover its deformation through its own rebound force. In other words, the thin sheet structure of the baffle 131 improves the installability of the cable protection clip 10 on the cavity 20.

[0062] Based on the above embodiment, the side of the carrier plate 11 away from the partition plate 13 is provided with a first abutment portion 111, which is used to abut and position itself against the first groove sidewall 211 of the mounting groove 21 on the cavity 20. In addition, the side of the partition plate 13 away from the carrier plate 11 is provided with a second abutment portion 133, which is used to abut and position itself against the second groove sidewall 212 of the mounting groove 21 on the cavity 20.

[0063] The final installation state of the cable protection clip 10 is as follows: First, the clip 14 is inserted into the slot 22; second, the first abutting part 111 abuts against the first slot side wall 211 of the mounting slot 21, and at the same time, the second abutting part 133 abuts against the second slot side wall 212 of the mounting slot 21. With the help of the fastening force and / or constraint force provided by the three mating parts (one clipping part 1212 and two abutting parts), the strength and reliability of the cable protection clip 10 installation can be greatly improved, and the cable protection clip 10 can be prevented from loosening or even falling off when subjected to environmental vibration impact or when the cable 30 is pulled.

[0064] The first abutting part 111 and the first groove sidewall 211, as well as the second abutting part 133 and the second groove sidewall 212, can be any one of planar abutting, concave-convex abutting, or a combination of at least two of them. By increasing the abutting area and / or constructing a concave-convex tenon and mortise structure, the stability of the assembly between the wire guard 10 and the cavity 20 can be significantly enhanced.

[0065] Please continue reading. Figures 1 to 4 In an optional embodiment, the cable clamp 12 includes a cable holder 121 with a recessed cable groove 1211 for securing the cable 30. The cable 30 is pressed into the cable groove 1211, and the groove wall secures the cable 30, achieving a secure installation. This installation method is simple and highly operable.

[0066] Furthermore, based on the above embodiment, the cable clamp 12 also includes a clamping member 122. The cable clamp base 121 is provided with a clamping part 1212. The clamping member 122 is used to clamp with the clamping part 1212, so that the clamping member 122 seals the opening of the cable clamping groove 1211 to constrain the cable 30 within the cable clamping groove 1211.

[0067] After the cable 30 is inserted into the cable clamping groove 1211, the clamping piece 122 is then engaged with the clamping part 1212. At this time, the clamping piece 122 seals the opening of the cable clamping groove 1211, so that the clamping piece 122 and the cable clamping seat 121 tightly enclose and clamp the cable 30. Even if subjected to external pulling force, the cable 30 is not easy to loosen and fall off the cable clamping seat 121. On the contrary, the greater the pulling force on the cable 30, the greater the squeezing force that pushes the clamping piece 122 away from the cable clamping seat 121, which makes the clamping piece 122 and the clamping part 1212 more tightly engaged, so that the clamping piece 122 forms a more effective restraint effect on the cable 30 installed in the cable clamping seat 121.

[0068] Please continue reading. Figures 1 to 2In one embodiment, the locking member 122 includes an elastic part 1221, a main body part 1222, and a hook part 1223. One side of the elastic part 1221 is connected to the locking wire seat 121, the other side of the elastic part 1221 is connected to one side of the main body part 1222, and the other side of the main body part 1222 is connected to the hook part 1223. The hook part 1223 can engage or disengage with the locking part 1212.

[0069] The clip 122 is connected to the clip seat 121 via the elastic part 1221. With the help of the excellent elastic deformation capability provided by the elastic part 1221, the clip 122 can repeatedly engage or disengage with the clip part 1212.

[0070] Furthermore, the elastic part 1221 also provides the locking member 122 with a certain degree of elastic avoidance capability. When the locking member 122 engages with the locking part 1212 and the locking member 122 clamps the cable 30, the pressure on the cable 30 will not be too great, which would cause the cable 30 to be crushed.

[0071] The main body 1222 is mainly used to cover the opening of the cable clamping groove 1211 and to clamp and confine the cable 30 within the cable clamping groove 1211. The hook part 1223 is used to engage or disengage with the engaging part 1212.

[0072] In one embodiment, the elastic part 1221 has an arc-shaped structure, and the arc-shaped concave part is set towards the cable clamping groove 1211. This design helps to reduce stress concentration when the elastic part 1221 is bent and deformed, preventing the elastic part 1221 from cracking or even breaking. On the other hand, when the hook part 1223 is engaged with the engaging part 1212, the main body part 1222 will not penetrate too much into the cable clamping groove 1211, thereby avoiding excessive squeezing force on the cable 30 and causing the cable 30 to be crushed.

[0073] Please continue reading. Figures 1 to 5 Furthermore, based on any of the above embodiments, the cable guard 10 also includes a first limiting body 15 and a second limiting body 16. The first limiting body 15 is connected to one end of the carrier plate 11 along the second direction of the cable guard 10, and the second limiting body 16 is connected to the other end of the carrier plate 11 along the second direction of the cable guard 10. The first limiting body 15 is used to engage with the first outer wall 23 of the cavity 20, and the second limiting body 16 is used to engage with the second outer wall 24 of the cavity 20. In this way, the assembly strength and connection firmness of the cable guard 10 and the cavity 20 can be further improved, preventing the cable guard 10 from loosening and causing pulling on the welding part of the cable 30, thus protecting the welding part from damage.

[0074] In addition to the above, this application also proposes a phase shifter 100, which includes a cavity 20, a cable 30 and a cable guard 10 as described in any of the above embodiments. The cavity 20 is provided with a mounting groove 21, the cable guard 10 is disposed in the mounting groove 21, and the cable 30 is installed in the cable guard 10.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
