[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] First Embodiment This invention provides a cable assembly with a connector, see below. Figures 1-4 It includes a cable 100 and a connector located at one end of the cable 100.

[0019] The cable 100 includes a conductor core 110 in the middle, a protective layer 120 on the outside of the conductor core 110, a shielding layer 130 on the outside of the protective layer 120, a braided layer 140 on the outside of the shielding layer 130, and a protective sleeve 150 on the outside of the braided layer 140. The protective sleeve 150 may be multi-layered, and the specific details are not limited.

[0020] The connector includes a connecting housing 200, one end of which forms a plug interface 210, and the other end has an integrally formed positioning tube 220, which communicates with the interior of the connecting housing 200. During installation, the conductor core 110, the protective layer 120, and the shielding layer 130 enter the connecting housing 200 from the inside of the positioning tube 220. A braided layer 140 is located outside the positioning tube 220; a locking structure 300 that cooperates with the positioning tube 220 is provided on the outside of the braided layer 140. After installation, the locking structure 300 connects and fixes the connecting housing 200 and the cable 100, improving the stability of the connection.

[0021] Specifically, the locking structure 300 includes a positioning ring 310, a first arc-shaped plate 320, a second arc-shaped plate 330, and a locking sleeve 340.

[0022] The positioning ring 310 is sleeved on the outside of the conductor core 110, the protective layer 120, the shielding layer 130 and the braided layer 140, and abuts against the end of the protective sleeve 150. The end of the positioning tube 220 away from the connecting housing 200 abuts against the positioning ring 310. During this process, the braided layer 140 is located outside the positioning tube 220.

[0023] An annular groove 221 is provided on the outer side of the positioning tube 220, and at least two annular grooves 221 are provided at intervals along the axial direction of the positioning tube 220.

[0024] The first arc-shaped plate 320 and the second arc-shaped plate 330 interlock and hug the positioning tube 220. A locking half-ring 331 is provided on the side of the first arc-shaped plate 320 and the second arc-shaped plate 330 that are close to each other. The locking half-ring 331 is fitted into the annular groove 221. The braided layer 140 is pressed between the positioning tube 220, the first arc-shaped plate 320 and the second arc-shaped plate 330. After installation, the braided layer 140 can be fixed by the positioning and locking of the annular groove 221 and the locking half-ring 331. At the same time, the locking structure 300 supports the connection position to prevent the connection position from breaking during use.

[0025] The outer sides of the first arc-shaped plate 320 and the second arc-shaped plate 330 are formed with external threads, and are threadedly connected to the locking sleeve 340 through these external threads. It should be noted that during the rotational connection process, the first arc-shaped plate 320 and the second arc-shaped plate 330 tightly grip the inner braided layer 140 and the positioning tube 220, and the first arc-shaped plate 320 and the second arc-shaped plate 330 will not rotate while the locking sleeve 340 rotates. After the threaded connection, the first arc-shaped plate 320 and the second arc-shaped plate 330 are tightly gripped with the positioning tube 220, clamping and fixing the braided layer 140 between them.

[0026] The positioning ring 310 abuts against the ends of the first arc-shaped plate 320 and the second arc-shaped plate 330, and the end of the locking sleeve 340 near the connecting housing 200 can pass through the positioning ring 310. The positioning ring 310 abuts against the first arc-shaped plate 320 and the second arc-shaped plate 330 from its ends, while also shielding and protecting the braided layer 140.

[0027] The locking sleeve 340 has a connecting tube 341 integrally formed at the end away from the connecting housing 200. The inner diameter of the connecting tube 341 is the same as the outer diameter of the cable 100. The outer diameter of the connecting pipe 341 is smaller than the outer diameter of the positioning ring 310; a sealing structure 400 is provided between the outer side of the protective sleeve 150 of the cable 100 and the connecting pipe 341. The sealing structure 400 is used to seal, connect and fix the connecting pipe 341 and the protective sleeve 150.

[0028] Specifically, the sealing structure 400 includes a first sealing plate 410 and a second sealing plate 420. Both the first and second sealing plates 410 and 420 have arc-shaped cross-sections. A first arc-shaped sealing strip 430 is formed at one end of each sealing plate 410 and 420 along its length, and a second arc-shaped sealing strip 440 is formed at the other end. Two first arc-shaped sealing strips 430 are bonded to the outside of the protective sleeve 150, and two second arc-shaped sealing strips 440 are bonded to the outside of the connecting pipe 341. The two sides of the first and second sealing plates 410 and 420 along their length are in close contact and sealed to each other. The first and second sealing plates 410 and 420 are detachably and fixedly connected.

[0029] The first sealing plate 410 has snap-fit ​​plates 450 on both sides along its length, with the length direction of the snap-fit ​​plates 450 perpendicular to the axis of the first sealing plate 410. A first thorn 451 is formed on the side of the snap-fit ​​plate away from the axis. Snap-fit ​​holes 460 are formed on both sides along the length of the second sealing plate 420, with the depth direction of the snap-fit ​​holes 460 perpendicular to the axis of the second sealing plate 420. A second thorn 461 is provided inside the snap-fit ​​hole 460 and on the side wall away from the axis. When the first sealing plate 410 and the second sealing plate 420 are engaged, the snap-fit ​​plates 450 are fitted into the snap-fit ​​holes 460, and the first thorn 451 and the second thorn 461 engage with each other. This arrangement ensures that after installation, the first sealing plate 410 and the second sealing plate 420 are locked together, sealing the connection between the connecting pipe 341 and the protective sleeve 150.

[0030] Even better, a pressing block is provided between the first sealing plate 410 and the second sealing plate 420, and between the first arc-shaped sealing strip 430 and the second arc-shaped sealing strip 440. The pressing block is arc-shaped and includes a first pressing block 470 on the first sealing plate 410 and a second pressing block 480 on the second sealing plate 420. The first pressing block 470 and the second pressing block 480 are aligned with each other, and anti-slip texture is provided on the side of the first pressing block 470 and the second pressing block 480 that are close to each other. The first pressing block 470 and the second pressing block 480 press and fix the protective sleeve 150. The height of the first pressing block 470 and the second pressing block 480 can be flush with or slightly higher than the first arc-shaped sealing strip 430. After installation, it is ensured that the first pressing block 470 and the second pressing block 480 press the protective sleeve 150 tightly, and the first arc-shaped sealing strip 430 is sealed and connected to the protective sleeve 150.

[0031] An outer sheath 500 is provided between the outer side of the protective sleeve 150 and the connecting housing 200, and the outer sheath 500 covers the locking structure 300 and the sealing structure 400. The outer sheath 500 shields the inner locking structure 300 and sealing structure 400, and at the same time, the outer sheath 500 can provide protection when the connection position shakes / moves. Specifically, the outer sheath 500 is made of heat-shrinkable material.

[0032] An installation ring 230 is integrally formed on the connecting housing 200 and located outside the positioning tube 220. The installation ring 230 is fixedly connected to the outer sheath 500. A cavity 240 is formed at one end of the connecting housing 200 near the insertion interface 210. A connecting sleeve 250 is formed inside the cavity 240. An inner filling layer 260 is provided inside the connecting sleeve 250. The conductor core 110 of the cable passes through the inner filling layer 260 and is located inside the connecting sleeve 250.

[0033] This invention provides a cable assembly with a connector. A locking structure 300 and a sealing structure 400 are disposed between the cable 100 and the connecting housing 200. The locking structure 300 reinforces and fixes the connection position between the cable 100 and the connecting housing 200, while the sealing structure 400 seals, connects, and fixes the connecting tube 341 and the protective sleeve 150. On the outside, an outer sheath 500 shields the inner locking structure 300 and sealing structure 400, and also provides protection during shaking / movement of the connection position. Therefore, the assembly comprehensively avoids breakage at the connection position, improves the moisture and humidity resistance of the connection position, greatly enhances the cable's performance, and reduces safety hazards.
