Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0033] As mentioned in the background section, communication cables are cables used to transmit signals, including optical fibers, coaxial cables, and twisted-pair cables. Radio frequency (RF) cables are a type of coaxial cable. SMA connectors are widely used threaded coaxial connectors used to connect RF cables in RF circuits to enable the transmission of RF signals.

[0034] SMA connectors consist of a male and a female connector. The male connector is typically located at the end of one RF cable, and the female connector is located at the end of another RF cable. The male connector can be inserted into the female connector to establish an electrical connection between the two RF cables.

[0035] In the field of wiring harness protection for industrial AGVs (Automated Guided Vehicles), there are many RF cables on the AGV body, which are densely arranged. Long-term operation of AGVs can cause wear on SMA connectors, resulting in loosening of the male and female connections and signal attenuation.

[0036] To ensure a secure connection of the radio frequency cable and prevent signal attenuation, this application provides a protective sleeve for a wire harness and a wire harness structure. The protective sleeve for the wire harness provided in this application will be described below.

[0037] See Figures 1 to 4 , Figure 1 A perspective view of the wire harness structure provided in the embodiment of this application in a connected state; Figure 2 A perspective view of the wire harness structure provided in the embodiment of this application in the disconnected state; Figure 3 for Figure 1 A partial cross-sectional view of the wire harness structure shown; Figure 4 for Figure 1 A 3D view of the protective sleeve used for the wire harness shown.

[0038] like Figures 1 to 4 As shown, the protective sleeve for the wire harness provided in this embodiment is used to cover the outside of the connector 200 of two radio frequency cables 100; the connector 200 includes a female head 210 and a male head 220; the female head 210 is disposed at the connection end of the first radio frequency cable 100A, and the male head 220 is disposed at the connection end of the second radio frequency cable 100B; the male head 220 is inserted into the female head 210.

[0039] The protective sleeve 300 for wire harnesses includes: male sleeve 310 and female sleeve 320.

[0040] The male sleeve 310 is fitted outside the female head 210, and the female sleeve 320 is fitted outside the male head 220.

[0041] The first end of the male sleeve 310 is inserted into the first end of the female sleeve 320.

[0042] The first radio frequency cable 100A passes through the second end of the male sleeve 310; the second radio frequency cable 100B passes through the second end of the female sleeve 320.

[0043] Specifically, such as Figures 1 to 3 As shown, the connector 200 in this embodiment of the application adopts an SMA connector, with the female head 210 and the male head 220 threaded together.

[0044] Among them, such as Figure 1 and Figure 2 As shown, a wire harness protective sleeve 300 is installed outside the connector 200. The wire harness protective sleeve 300 is a split type, and its male sleeve 310 and female sleeve 320 can follow the female head 210 and male head 220 respectively to realize the connection and disconnection of the two radio frequency cables 100.

[0045] The wire harness protective sleeve provided in this embodiment is fitted over the connector 200 of two radio frequency cables 100, protecting the connector 200 from wear and signal interference caused by contact with other metal parts. It also prevents signal attenuation due to loose connection between the female and male connectors 210 and 220, ensuring the AGV can operate normally for extended periods. The male sleeve 310 of the wire harness protective sleeve 300 is fitted over the female connector 210, and the female sleeve 320 is fitted over the male connector 220, with the first end of the male sleeve 310 inserted into the first end of the female sleeve 320. This allows the wire harness protective sleeve 300 to be reused multiple times and quickly installed and removed, ensuring efficient connection and disconnection of the two radio frequency cables 100, thereby improving the efficiency of AGV maintenance.

[0046] In some embodiments of this application, the male sleeve 310 and the female sleeve 320 are made of plastic materials, such as PVC and silicone. By using plastic materials in the embodiments of this application, the protective sleeve 300 for the wire harness is made lighter and more insulating, wear-resistant, and dustproof. It also gives the protective sleeve 300 a certain degree of elasticity, so that when the male sleeve 310 is inserted into the female sleeve 320, the limiting protrusion 311 on the male sleeve 310 can pass through the locking block 321 at the first end of the female sleeve 320, allowing the locking block 321 to insert into the locking groove 312. See the subsequent description for details.

[0047] In some embodiments of this application, see Figures 5 to 7 , Figure 5 for Figure 4 Half-sectional view of the protective sleeve for the wire harness shown; Figure 6 for Figure 4 A three-dimensional view of the male sleeve shown; Figure 7 for Figure 4 A perspective view of the female sleeve is shown. Figures 4 to 7 As shown, a plurality of outward limiting protrusions 311 are provided on the outer wall of the first end of the male sleeve 310.

[0048] Multiple limiting protrusions 311 are spaced apart along the length of the male sleeve 310; a groove 312 is formed between two adjacent limiting protrusions 311.

[0049] An inwardly facing locking block 321 is provided on the inner wall of the first end of the female sleeve 320.

[0050] The locking block 321 is used to insert into the locking groove 312 when the first end of the male sleeve 310 is inserted into the first end of the female sleeve 320.

[0051] By using the embodiments of this application, the male sleeve 310 and the female sleeve 320 can be interlocked by the locking block 321 and the limiting protrusion 311, and the insertion and removal are convenient, which ensures the efficiency of connecting and disconnecting the two radio frequency cables 100, thereby improving the efficiency of AGV maintenance.

[0052] Specifically, such as Figure 5 and Figure 6 As shown, along the length of the male sleeve 310, there can be two limiting protrusions 311, and correspondingly, one slot 312. The cross-sectional dimension of the male sleeve 310 at the location where the limiting protrusions 311 are set is not greater than the cross-sectional dimension of the inner wall of the first end of the female sleeve 320, so that the male sleeve 310 can be smoothly inserted into the female sleeve 320. The dimensions of the slot 312 along both the length and width directions of the male sleeve 310 are consistent with the dimensions of the locking block 321, so that the locking block 321 can be accommodated in the slot 312.

[0053] During the connection of male sleeve 310 and female sleeve 320, when the locking block 321 of female sleeve 320 passes the first limiting protrusion 311, it can enter the locking groove 312. At this time, the limiting protrusions 311 on both sides of the locking groove 312 can play a limiting role to prevent the male sleeve 310 and female sleeve 320 from moving along the length direction, so as to improve the stability of the connection between male sleeve 310 and female sleeve 320.

[0054] The number of limiting protrusions 311 can be more, for example, 3, and correspondingly, the number of slots 312 is 2. At this time, the card block 321 can be inserted into one of the slots 312 according to the length dimension of the connector 200, so that the wire harness protective sleeve 300 can be used for connectors 200 of different specifications.

[0055] In some embodiments of this application, such as Figure 6 and Figure 7 As shown, the limiting protrusion 311 and the locking block 321 can be annular. When connecting two radio frequency cables 100, first align the female head 210 and the male head 220, then twist the female head 210 and the male head 220 relative to each other to make the female head 210 and the male head 220 threadedly connected, and insert the first end of the male sleeve 310 into the first end of the female sleeve 320 so that the locking block 321 is inserted into the locking groove 312, thereby completing the connection.

[0056] The limiting protrusion 311 and the locking block 321 can also be arc-shaped, for example, when... Figure 6 The complete annular limiting protrusion 311 shown is symmetrically cut off in two sections, so that the complete annular limiting protrusion 311 becomes two symmetrical arc-shaped limiting protrusions 311. Correspondingly, the complete annular locking block 321 is also symmetrically cut off in two sections, so that the complete annular locking block 321 becomes two symmetrical arc-shaped locking blocks 321.

[0057] At this point, there are two methods for connecting the male sleeve 310 and the female sleeve 320: The first method is to align the arc-shaped locking block 321 and the arc-shaped limiting protrusion 311 before inserting the first end of the male sleeve 310 into the first end of the female sleeve 320, and then insert it directly, allowing the arc-shaped locking block 321 to pass over the first ring of the arc-shaped limiting protrusion 311 and into the slot 312; the second method is to align the arc-shaped locking block 321 and the arc-shaped limiting protrusion 311 before inserting the first end of the male sleeve 310 into the first end of the female sleeve 320, and then... The positions of block 321 and arc-shaped limiting protrusion 311 are staggered so that the two arc-shaped locking blocks 321 are aligned with the cutting gap between the two arc-shaped limiting protrusions 311. Then, the male sleeve 310 is inserted into the female sleeve 320. After the arc-shaped locking blocks 321 pass through the cutting gap, the male sleeve 310 and the female sleeve 320 are rotated relative to each other to align the positions of the arc-shaped locking blocks 321 and the arc-shaped limiting protrusions 311, so that the arc-shaped limiting protrusions 311 limit the arc-shaped locking blocks 321.

[0058] By applying the embodiments of this application, the limiting protrusion 311 and the locking block 321 are set as rings. Compared with setting them as arcs, it is not necessary to align the positions of the limiting protrusion 311 and the locking block 321 to directly insert and remove them. This makes the connection and disconnection of the male sleeve 310 and the female sleeve 320 more convenient, thereby further improving the efficiency of AGV maintenance. It also makes the appearance of the male sleeve 310 and the female sleeve 320 more beautiful and less prone to wear.

[0059] In some embodiments of this application, such as Figures 2 to 5 As shown, the male sleeve 310 includes: a first connecting sleeve 313 located at its first end and a first cable sleeve 314 located at its second end; the first connecting sleeve 313 and the first cable sleeve 314 are interconnected.

[0060] The first connecting sleeve 313 is used to wrap the female head 210 and fit tightly with the female head 210; the first cable sleeve 314 is used to wrap the portion of the first radio frequency cable 100A extending from the female head 210, and the cross-sectional size of the first cable sleeve 314 is not greater than the cross-sectional size of the first connecting sleeve 313.

[0061] The female sleeve 320 includes a second connecting sleeve 322 located at its first end and a second cable sleeve 323 located at its second end; the second connecting sleeve 322 and the second cable sleeve 323 are interconnected.

[0062] The second connecting sleeve 322 is used to wrap the male connector 220; the second cable sleeve 323 is used to wrap the portion of the second radio frequency cable 100B extending from the male connector 220, and the cross-sectional dimension of the second cable sleeve 323 is not greater than the cross-sectional dimension of the second connecting sleeve 322.

[0063] Part of the first connecting sleeve 313 is inserted into the second connecting sleeve 322 and is detachably connected to the second connecting sleeve 322.

[0064] Specifically, the second connecting sleeve 322 and the male connector 220 can be tightly fitted to restrict the swing of the male connector 220; or it can be as follows: Figure 2 As shown, the second connecting sleeve 322 has a large space inside, which allows the male connector 220 to be inserted into the female connector 210, and also restricts the swing of the male connector 220. Therefore, this application does not limit the way the second connecting sleeve 322 and the male connector 220 are fitted together.

[0065] In the embodiments of this application, the cross-sectional dimension of the first cable sleeve 314 is not greater than the cross-sectional dimension of the first connecting sleeve 313, and the cross-sectional dimension of the second cable sleeve 323 is not greater than the cross-sectional dimension of the second connecting sleeve 322. That is, the inner diameters of the first cable sleeve 314 and the second cable sleeve 323 are small, which can play a role in constraining and fixing the radio frequency cable 100.

[0066] In the embodiments of this application, the specific shapes of the cable sleeve and the connecting sleeve are not limited, and they can both be cylindrical, prismatic, etc. The cable sleeve can also be conical, as detailed in the following description.

[0067] In some embodiments of this application, such as Figures 4 to 7 As shown, the first connecting sleeve 313 and the second connecting sleeve 322 are cylindrical, while the first cable sleeve 314 and the second cable sleeve 323 are conical.

[0068] The diameter of the first cable sleeve 314 gradually decreases in the direction away from the first connecting sleeve 313, and a first through hole 315 is provided at the end away from the first connecting sleeve 313 so that the first radio frequency cable 100A can pass through.

[0069] The diameter of the second cable sleeve 323 gradually decreases in the direction away from the second connecting sleeve 322, and a second through hole 324 is provided at the end away from the second connecting sleeve 322 for the second radio frequency cable 100B to pass through.

[0070] In the embodiments of this application, the diameter of the first cable sleeve 314 continuously decreases in the direction away from the first connecting sleeve 313, and the diameter of the second cable sleeve 323 continuously decreases in the direction away from the second connecting sleeve 322. Compared with a cylindrical shape whose diameter remains constant, the conical cable sleeve can further constrain and fix the radio frequency cable 100, preventing the section of the radio frequency cable 100 extending from the connector 200 from bending and breaking.

[0071] In some embodiments of this application, see Figure 8 and Figure 9 , Figure 8 for Figure 4Right view of the protective sleeve for the wire harness shown; Figure 9 for Figure 4 The left view of the protective sleeve used for the wire harness shown. Figures 4 to 9 As shown, a plurality of first grooves 316 are provided through the side wall of the first cable sleeve 314; the opening of the first groove 316 faces the first through hole 315 and is connected to the first through hole 315.

[0072] A plurality of second grooves 325 are provided through the side wall of the second cable sleeve 323; the openings of the second grooves 325 face the second through hole 324 and are connected to the second through hole 324.

[0073] In the embodiments of this application, a plurality of first grooves 316 are provided on the side wall of the first cable sleeve 314, and a plurality of second grooves 325 are provided on the side wall of the second cable sleeve 323, so that the first cable sleeve 314 and the second cable sleeve 323 are arranged in a multi-lobed manner. When the radio frequency cable 100 with a larger diameter passes through the first through hole 315 or the second through hole 324, the lobe structure of the first cable sleeve 314 or the second cable sleeve 323 can be opened to allow the radio frequency cable 100 to pass through, so that the wire harness protective sleeve 300 can be adapted to a variety of radio frequency cables 100 with different diameters, and the wire harness protective sleeve 300 has universality.

[0074] In some embodiments of this application, such as Figure 8 and Figure 9 As shown, a plurality of first grooves 316 are evenly or symmetrically distributed on the side wall of the first cable sleeve 314; a plurality of second grooves 325 are evenly or symmetrically distributed on the side wall of the second cable sleeve 323.

[0075] Specifically, when the number of the first groove 316 and the second groove 325 is 2, such as Figure 8 and Figure 9 As shown, the two first grooves 316 or the second grooves 325 are both uniformly distributed and symmetrically distributed.

[0076] It should be noted that, as Figure 4 , Figure 8 and Figure 9 As shown, there is an angular deviation between the first groove 316 and the second groove 325, that is, Figure 8 Two first grooves 316 are shown to be vertically arranged. Figure 9 The diagram shows two second grooves 325 horizontally positioned, differing by 90°. In actual installation of the male sleeve 310 and female sleeve 320, the angular deviation between the first groove 316 and the second groove 325 can be any value, not limited to the situation shown in the figure.

[0077] When the diameter of the radio frequency cable 100 is large, the first groove 316 and the second groove 325 are evenly or symmetrically distributed, so that the structure of each lobe of the first cable sleeve 314 and the second cable sleeve 323 can be subjected to uniform force and are not easily damaged.

[0078] In some embodiments of this application, such as Figure 2 , Figure 3 and Figure 6 As shown, the female head 210 of the connector 200 has a hexagonal threaded ring 211; the area on the first end of the male sleeve 310 for mating with the hexagonal threaded ring 211 has a hexagonal cross-section on its inner wall, and the size of the hexagon is the same as that of the hexagonal threaded ring 211.

[0079] In this embodiment of the application, compared to the circular cross-section of the inner wall of the first end of the male sleeve 310, the cross-section of the inner wall of the first end of the male sleeve 310 that mates with the hexagonal threaded ring 211 is set to hexagonal. This makes the connection between the male sleeve 310 and the female head 210 more stable and prevents relative rotation. This further prevents the connector 200 from loosening and improves the protective effect of the wire harness protective sleeve 300.

[0080] This application also provides a wire harness structure, such as... Figures 1 to 3 As shown, it includes the radio frequency cable 100, connector 200 and wire harness protective sleeve 300 described in any of the above embodiments.

[0081] The wiring harness structure provided in this application embodiment has a protective sleeve 300 that is fitted over the connector 200 of two radio frequency cables 100. This sleeve protects the connector 200 from wear and prevents signal attenuation caused by loose connection between the female and male connectors 210 and 220. The male sleeve 310 of the protective sleeve 300 is fitted over the female connector 210, and the female sleeve 320 is fitted over the male connector 220. The first end of the male sleeve 310 is inserted into the first end of the female sleeve 320, allowing the protective sleeve 300 to be reused multiple times and quickly installed and removed, ensuring efficient connection and disconnection of the two radio frequency cables 100.

[0082] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
