The snap-fit ​​assembly includes mounting slots symmetrically formed on the outer side wall of the second housing. A spring is fixedly provided at the bottom of each of the two mounting slots, and a ball is fixedly provided at the upper end of each of the two springs. Multiple snap-fit ​​slots adapted to the balls are formed on the inner circumferential wall of the mounting cavity. The lower end of the second housing is provided with a rotating assembly. The rotating assembly includes a first connecting block fixedly disposed at the lower end of the second housing. A rotating shaft is fixedly disposed at the middle position of both ends of the first connecting block. A second connecting block is rotatably sleeved on the outer surface of the rotating shaft. Both the first connecting block and the second connecting block have through holes in their middle portions for cables to pass through.

[0006] As a further embodiment of this utility model, the spring is coaxially sleeved with a telescopic sleeve rod inside. The telescopic sleeve rod is composed of an inner rod and an outer cylinder nested together, and the axial length of the sleeve rod matches the maximum compression of the spring.

[0020] In the field of connector technology, SMB bendable cable connectors, in practical applications, cannot flexibly adjust their bending angle according to actual installation space, wiring requirements, or equipment layout. This fixed-angle design exposes many problems in complex engineering environments: when the internal space of the equipment is narrow, the wiring path is complex, or it is necessary to avoid other components, the fixed-angle SMB bendable connector often fails to adapt to the installation requirements, which may lead to excessive bending of the cable, uneven stress, or increased signal transmission loss. In severe cases, it may even cause the connector to loosen or have poor contact due to concentrated mechanical stress, thereby affecting the stability and service life of the entire electronic system.

[0021] Therefore, developing an SMB bendable cable connector with flexible bending angle adjustment has become an urgent technological breakthrough requirement in the industry. This new connector needs to overcome the limitations of traditional fixed-angle structures and achieve multi-position precise positioning through innovative mechanical structure design. This allows it to flexibly adapt to various complex engineering scenarios based on different installation space dimensions, wiring path requirements, and device interface layout characteristics. The specific implementation method is as follows: Example 1: Please refer to Figure 1 , Figure 2 As shown, an adjustable angle SMB bend cable connector includes a first housing 1, the lower end of the first housing 1 is hollow to form a mounting cavity 2, a second housing 3 is rotatably snapped into the mounting cavity 2, and a snap-fit ​​assembly 4 is provided at the upper end of the second housing 3, the snap-fit ​​assembly 4 is used to snap the first housing 1 and the second housing 3 into each other. Specifically, please refer to Figure 6As shown, the snap-fit ​​assembly 4 includes mounting grooves 41 symmetrically opened on the outer side wall of the upper end of the second housing 3. A spring 42 is fixedly installed at the bottom of the mounting groove 41. A telescopic sleeve rod for limiting the deformation direction of the spring 42 is coaxially sleeved inside the spring 42. The telescopic sleeve rod is composed of an inner rod and an outer cylinder nested together. The axial length of the sleeve rod should match the maximum compression of the spring 42 and be able to move axially synchronously with the compression or extension of the spring 42, thereby effectively ensuring the consistency of the displacement of the spring 42 during the deformation process under force, avoiding the spring 42 from shifting left or right or tilting due to lateral force, and ensuring the stable working performance of the snap-fit ​​assembly 4. A ball 43 is fixedly installed at the upper end of the spring 42. Multiple slots 44 are opened on the inner side wall of the mounting cavity 2. The slots 44 are adapted to the ball 43. The slots 44 are evenly distributed along the inner side wall of the mounting cavity 2. The central angle of adjacent slots 44 is the minimum adjustment angle (one slot 44 is set every 30° to realize six-level adjustment within the range of 0°-360°). In this embodiment, when the bending angle needs to be adjusted, the operator applies external force to cause the first outer shell 1 and the second outer shell 3 to rotate relative to each other. At this time, the inner wall of the mounting cavity 2 generates lateral pressure on the ball 43, forcing the ball 43 to compress the spring 42 and drive the telescopic sleeve rod to retract synchronously. The ball 43 is dislodged from the current slot 44 and slides along the inner wall of the mounting cavity 2. As the rotation angle changes, the ball 43 always fits against the inner wall of the mounting cavity 2 under the elastic thrust of the spring 42. When the target angle is reached, the ball 43 aligns with the corresponding slot 44, and the spring 42 resets and pushes the ball 43 into the slot 44 to complete the locking, thereby achieving reliable fixation of the first outer shell 1 and the second outer shell 3 at the target angle and achieving flexible adjustment and locking of the bending angle.

[0022] Example 2: Based on Example 1, please refer to... Figure 3 , Figure 4 As shown, a rotating assembly 5 is provided at the lower end of the second housing 3. The rotating assembly 5 includes a first connecting block 51 fixedly disposed at the lower end of the second housing 3. The interior of the first connecting block 51 is provided with a through hole with a diameter matching the outer diameter of the cable along the axial direction, ensuring that the cable can pass through unobstructed and reducing signal transmission interference. A rotating shaft 52 is fixedly disposed at the middle position of both ends of the first connecting block 51. A second connecting block 53 for connecting the cable is rotatably sleeved on the outer surface of the rotating shaft 52 through a bearing. A fastening bolt for locking the rotation angle is threadedly connected to the outer side of the second connecting block 53 at the end of the rotating shaft 52 away from the first connecting block 51. The second connecting block 53 also has a through hole through which the cable can pass. The axes of the two through holes are coplanar in the plane of rotation, and the inner diameter of the through hole is larger than the outer diameter of the cable, ensuring that the cable will not be squeezed or excessively bent due to the included angle of the axes during rotation. The four corners of the first connecting block 51 are all designed with rounded transitions to form arc surfaces. The upper and lower ends of the second connecting block 53 facing the first connecting block 51 are fixed with arc-shaped baffles 54 that are adapted to the arc surfaces. A small gap is maintained between the arc baffles 54 and the arc surfaces, which can effectively block dust and impurities from entering the rotation gap without affecting the rotation, and at the same time limit the range of rotation angle to prevent excessive rotation from damaging the cable.

[0023] Specifically, please refer to Figure 4 As shown, the second connecting block 53 and the first connecting block 51 are provided with the same structure as the snap-fit ​​assembly 4. The spring 42 and the ball 43 inside the mounting groove 41 of the second connecting block 53 cooperate with each other, and the ball 43 snaps into the snap-fit ​​groove 44 inside the first connecting block 51, thereby realizing the snap-fit ​​limit between the second connecting block 53 and the first connecting block 51.

[0024] In this embodiment, a through hole with a diameter matching the outer diameter of the cable is opened along the axis inside the first connecting block 51, providing an unobstructed channel for the cable to reduce signal interference. A rotating shaft 52, coaxially fixed at the center of both ends, is rotatably connected to the second connecting block 53 via bearings, allowing the second connecting block 53 to rotate flexibly around the rotating shaft 52. After rotation, the angle is locked by a fastening bolt at the outer end of the rotating shaft 52. The axis of the through hole inside the second connecting block 53 always corresponds to the axis of the through hole in the first connecting block 51 during rotation, preventing excessive bending of the cable. The rounded arc transition surfaces at the four corners of the first connecting block 51 form a matching structure with the arc-shaped baffles 54 fixed at the upper and lower ends of the second connecting block 53. The small gap between them does not affect rotation, but also prevents dust and impurities from entering, while limiting the rotation angle to prevent cable damage. In addition, the second connecting block 53 and the first connecting block 51 cooperate through the spring 42 and ball 43 in the mounting groove 41. The ball 43 is inserted into the slot 44 to achieve locking and limiting, which further ensures the stability of the rotation process. The locking component 4 is used for "pre-positioning" (temporarily fixing the angle during rotation for easy operation), and the fastening bolt is used for "final locking" (ensuring the stability of the angle during long-term use).

[0025] Example 3: Please refer to Figure 5As shown, the medium 6 is assembled inside the first outer shell 1 using a press-fit process. This medium 6 is an insulating component (commonly made of high-temperature resistant insulating plastics such as PPS and PTFE). Its core function is to fix the socket 7 and achieve electrical isolation between the socket 7 and the metal first outer shell 1, fundamentally preventing short circuits caused by contact between the two. To ensure structural stability, the outer wall of the medium 6 and the inner wall of the first outer shell 1 are designed as a tight fit. Simultaneously, the pre-set stepped structure on the inner wall of the first outer shell 1 effectively limits the axial displacement of the medium 6, ensuring that the insulating support position remains stable at all times. Specifically, please refer to Figure 6 As shown, a through hole is provided inside the dielectric 6, and a socket 7 is also fixed inside the through hole using a press-fit process. The socket 7 integrates a contact head 8 and a cable body 9. During the assembly of the cable body 9, its end insulation layer must first be stripped, and the exposed metal core wire (i.e., the signal transmission line) is fixed to the solder joint at the tail of the socket 7 using soldering or laser welding to form a stable conductive path. After welding, the solder joint must be cleaned of solder slag, and the welding quality must be strictly checked to ensure there are no cold solder joints. Cold solder joints can lead to signal attenuation during transmission, and in severe cases, even cause open circuits, affecting the overall performance of the connector. Regarding the treatment of the shielding layer of the cable body 9, firstly, the shielding layer at the end of the cable body 9 is stripped off, and the stripped shielding layer is folded over and tightly wrapped around the outer wall of the tail of the first housing 1; then, the crimp tube 10 is installed. The crimp tube 10 is a metal sleeve (the material must match the first housing 1, such as brass). Before installation, it must be pre-fitted onto the outside of the shielding layer of the cable body 9. Through the tightening action of the crimp tube 10, a reliable connection between the shielding layer and the outer wall of the tail of the first housing 1 is ensured, thereby ensuring the electromagnetic shielding performance of the connector.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
