Description

Technical Field

[0001] This utility model relates to the field of radio frequency communication harness technology, and in particular to a tensile-resistant radio frequency communication harness. Background Technology

[0002] Radio frequency communication harnesses are specialized connection components used for high-frequency signal transmission. Their core task is to achieve high-fidelity transmission of high-frequency electrical signals while suppressing signal loss and electromagnetic interference.

[0003] Existing RF communication harnesses are mostly made of soft materials. When the connection between the main connector and the harness is subjected to frequent pulling, it is prone to loosening and breakage, resulting in communication failure or signal distortion. The overall tensile strength needs to be improved.

[0004] Therefore, in response to the problem that the overall tensile strength of the radio frequency communication harness needs to be improved, this utility model improves the tensile strength of the harness by setting a heat shrink tubing at the junction of the main connector and the communication harness, thereby enhancing the structural strength of the connection. In addition, by setting an auxiliary pulling component, the force is dispersed and guided during the insertion and removal operation, which significantly reduces the risk of tensile stress concentration at the connection point, thereby improving the overall service life of the harness and the reliability of the connection. Utility Model Content

[0005] In order to overcome the problem that the overall tensile strength of common radio frequency communication harnesses needs to be strengthened.

[0006] The technical solution of this utility model is: a tensile-resistant radio frequency communication harness, including a main connector, a communication harness body, a secondary connector and a heat shrink tubing, wherein the communication harness body is connected and installed between the main connector and the secondary connector, and the heat shrink tubing is installed at the joint between the main connector and the communication harness body.

[0007] An auxiliary traction component is provided on the outside of the main connector, and a positioning adjustment component is provided below the auxiliary traction component.

[0008] Preferably, the auxiliary traction assembly includes positioning support bars, positioning support blocks, limiting support shafts, and hollow sleeves. Positioning support bars are symmetrically fixedly installed on the top outer wall of the main connector located in the housing position. Positioning support blocks are slidably installed on the top outer walls of both sets of positioning support bars. A limiting support shaft is fixedly connected and installed between the two sets of positioning support blocks. A hollow sleeve is installed on the outer cover of the limiting support shaft, and the hollow sleeve is rotatably connected and installed in the middle position of the two sets of positioning support blocks.

[0009] Preferably, a torsion spring is sleeved on the outside of the limiting support shaft. One end of the torsion spring is connected to the outer side wall of the limiting support shaft, and the other end of the torsion spring is connected to the inner side wall of the hollow sleeve. A handle is fixedly installed on the outer side wall of the hollow sleeve at the annular surface position.

[0010] Preferably, the handle is composed of a square extension plate and a pull post, and a pull groove is provided at the connection between the square extension plate and the pull post.

[0011] Preferably, the positioning adjustment component includes a limiting T-block and a limiting T-groove. The bottom outer wall of both sets of positioning support blocks is provided with a limiting T-block, and the top outer wall of both sets of positioning support bars is provided with a limiting T-groove for sliding installation of the limiting T-block.

[0012] Preferably, the positioning support bar has positioning threaded grooves evenly spaced on the outer side wall of the limiting T-shaped groove, the positioning threaded grooves are connected to the internal space of the limiting T-shaped groove, and the outer side wall of the limiting T-shaped block has mating threaded grooves. A fastening bolt is installed on the internal threads of a single set of positioning threaded grooves and mating threaded grooves.

[0013] The beneficial effects of this utility model are:

[0014] 1. When using this tensile-resistant radio frequency communication harness, heat shrink tubing is installed at the junction of the main connector and the communication harness, which enhances the structural strength of the connection and improves the tensile performance of the harness. In addition, by setting an auxiliary pulling component, the force is dispersed and guided during the insertion and removal operation, which significantly reduces the risk of tensile stress concentration at the connection point, thereby improving the overall service life of the harness and the reliability of the connection.

[0015] 2. When in use, the tension-resistant radio frequency communication harness uses a sliding fit between the limiting T-block and the T-slot, supplemented by a locking mechanism of the positioning threaded groove and the fastening bolt. This allows the extension length of the handle to be flexibly adjusted according to actual installation needs, so as to adapt to equipment interfaces of different sizes and installation angles, thereby improving the adaptability and ease of installation of the equipment. At the same time, the resettable torsion spring design further enhances the overall operability and portability of the device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a tensile-resistant radio frequency communication harness, including a main connector 1, a communication harness body 2, a secondary connector 3 and a heat shrink tubing 4. The communication harness body 2 is connected and installed between the main connector 1 and the secondary connector 3, and the heat shrink tubing 4 is installed at the joint between the main connector 1 and the communication harness body 2.

[0024] An auxiliary traction component 5 is provided on the outer side of the main connector 1, and a positioning adjustment component 6 is provided below the auxiliary traction component 5.

[0025] The auxiliary traction assembly 5 includes positioning support bars 501, positioning support blocks 502, limiting support shafts 503, and hollow sleeves 504. Positioning support bars 501 are symmetrically fixedly installed on the top outer wall of the main connector 1 at the housing position. Positioning support blocks 502 are slidably installed on the top outer walls of both sets of positioning support bars 501. Limiting support shafts 503 are fixedly connected between the two sets of positioning support blocks 502. Hollow sleeves 504 are installed over the outer cover of the limiting support shafts 503, and the hollow sleeves 504 are rotatably connected... A torsion spring 505 is installed on the outside of the limiting support shaft 503, which is installed in the middle of the two sets of positioning support blocks 502. One end of the torsion spring 505 is connected to the outer side wall of the limiting support shaft 503, and the other end of the torsion spring 505 is connected to the inner side wall of the hollow sleeve 504. A handle 506 is fixedly installed on the outer side wall of the hollow sleeve 504 at the annular surface position. The handle 506 is composed of a square extension plate and a pull column, and a pull groove is opened at the connection between the square extension plate and the pull column.

[0026] The two sets of positioning support blocks 502 here play an auxiliary role in limiting and supporting the limiting support shaft 503 and the hollow sleeve 504. On the basis of ensuring the stable support of the limiting support shaft 503 and the hollow sleeve 504, they provide a basic guarantee for the stable connection of the handle 506 described later.

[0027] The positioning adjustment component 6 includes a limiting T-block 601 and a limiting T-groove 602. The bottom outer wall of both sets of positioning support blocks 502 is provided with a limiting T-block 601. The top outer wall of both sets of positioning support bars 501 is provided with a limiting T-groove 602 for sliding installation of the limiting T-block 601. The side outer wall of the positioning support bar 501 located at the position of the limiting T-groove 602 is provided with positioning thread grooves 603 at equal intervals. The internal space of the positioning thread groove 603 and the limiting T-groove 602 is connected. The side outer wall of the limiting T-block 601 is provided with a mating thread groove 604. The internal threads of the positioning thread groove 603 and the mating thread groove 604 are installed with fastening bolts 605.

[0028] The T-shaped block 601 and the T-shaped groove 602 here provide a limiting support for the positioning support block 502, while the fastening bolt 605 provides a limiting and locking effect for the installation of the positioning support block 502.

[0029] Working principle: See Figures 1-2 As shown, the heat shrink tubing 4 here reinforces the connection between the main connector 1 and the communication harness body 2, making it less likely to come loose during actual use. The main connector 1 and the secondary connector 3 can be connected to the device normally during actual use.

[0030] See Figure 1 and Figure 3As shown, when it is necessary to pull the main connector 1 out from the side of the corresponding device, the handle 506 needs to be lifted upwards first. The upward tilting of the handle 506 will automatically drive the hollow sleeve 504 to rotate. At this time, the torsion spring 505 is tightened by the rotation of the hollow sleeve 504. Then, pull the handle 506 outwards directly. The movement of the handle 506 will automatically drive the main connector 1 to move, so that it can be removed from the outside of the corresponding device. Then, release the handle 506. The torsion spring 505 will automatically release its force without being pulled and simultaneously drive the handle 506 to reset.

[0031] See Figures 3-5 As shown, when the extension length of the handle 506 needs to be adjusted according to the installation space of the main connector 1, the fastening bolt 605 needs to be unscrewed from the inside of the positioning threaded groove 603 first, so that the limiting T-block 601 changes from the locked state to the movable state. Then, the positioning support block 502 is directly pushed to the appropriate installation position. The movement of the positioning support block 502 will automatically drive the hollow sleeve 504 to move, which in turn drives the handle 506 to move. When the handle 506 moves to the appropriate extension length, the fastening bolt 605 is passed through the positioning threaded groove 603 at the corresponding position and screwed to the bottom of the mating threaded groove 604. This completes the adjustment process of the handle 506.

[0032] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
