Description

Technical Field

[0001] The utility model relates to the technical field of servo motors, and more particularly to a servo motor wiring harness with adjustable length. Background Art

[0002] Servo motor wiring harnesses are specifically designed to connect the various components in a servo system, providing power and control for the servo motor. They feature excellent high-frequency response characteristics and minimal heat loss, ensuring minimal signal attenuation and delay, thereby significantly improving the servo motor's operating efficiency.

[0003] Authorization publication number "CN209709645U" discloses a servo motor wiring harness with adjustable length, which relates to the field of wiring harness technology. The servo motor wiring harness with adjustable length includes a baffle, a screw hole is provided on the bottom outer wall of the baffle, and a turning handle is connected to the internal thread of the screw hole. A winding device is fixedly connected to the side of the baffle away from the screw hole, and the end of the winding device away from the baffle is fixedly connected to the limit plate. The servo motor wiring harness with adjustable length is provided with a wire outlet hole, and the wire harness is passed through the wire outlet hole through the winding column. The wire harness is wound around the winding column surface by utilizing the transparent groove provided on the winding column surface. The turning handle is rotated to cause the baffle to drive the winding column to rotate, thereby winding the wire harness around the winding column surface. The first spring fixedly connected to the winding column through the mounting plate rotates on the convex ring surface. The first spring is continuously slid on the convex ring surface to limit the rotation speed of the winding column and prevent the wire harness from being stuck on the winding column surface.

[0004] At present, most of the existing servo motor wiring harnesses are adjusted in length by storage, so that the length of the wiring harness can be reasonably used according to actual conditions. However, when the storage structure is applied to the servo motor wiring harness, the overall volume of the servo motor wiring harness will be too large, thereby affecting the layout of the wiring harness. Moreover, the overall storage structure is relatively complex, which will increase the cost of the servo motor wiring harness. Utility Model Content

[0026] Example:

[0027] See also Figure 1-4 A servo motor wiring harness with adjustable length includes a wiring harness body 1, a plurality of bending slots 2 and a plurality of limiting slots 3 are provided on the circumferential surface of the wiring harness body 1, and each limiting slot 3 is located between two adjacent bending slots 2, and the circumferential surface of the wiring harness body 1 is rotatably connected to two rotating card rods 4, and the two rotating card rods 4 are slidably connected to a middle card rod 5, and the two middle card rods 5 are slidably connected to a locking card rod 6, and the two rotating card rods 4, the two middle card rods 5 and the two locking card rods 6 are all provided with a card slot 7, and the multiple card slots 7 match the multiple limiting slots 3, and a buckle assembly 8 is provided at one end of the two locking card rods 6, which is used to fix the two locking card rods 6.

[0028] In this embodiment, when the wiring harness body 1 is too long, the wiring harness body 1 is bent through multiple bending slots 2. After bending, multiple limit slots 3 are located on the same straight line corresponding to the two rotating card rods 4. The two middle card rods 5 and the two locking card rods 6 are telescopically adjusted according to the length of the bent part of the wiring harness body 1. The two rotating card rods 4 drive the two middle card rods 5 and the two locking card rods 6 to rotate. The multiple slots 7 on the two rotating card rods 4, the two middle card rods 5 and the two locking card rods 6 correspond to the multiple limit slots 3 respectively. At the same time, the buckle assembly 8 fixes the two locking card rods 6, and the two rotating card rods 4 and the two middle card rods 5 are also fixed, so that the bent part of the wiring harness body 1 is limited between the two rotating card rods 4, the two middle card rods 5 and the two locking card rods 6, shortening the length of the wiring harness body 1 and keeping the wiring harness body 1 at the required length. When the wiring harness body 1 is too short, the two locking card rods 6 are opened by the buckle assembly 8, and the bent part of the wiring harness body 1 is taken out to adjust the wiring harness body 1 to the required length.

[0029] Specifically, the buckle assembly 8 includes a locking piece 81 and an elastic buckle 82 . The locking piece 81 and the elastic buckle 82 are respectively fixedly connected to one end of the two locking rods 6 , and the locking piece 81 and the elastic buckle 82 match each other.

[0030] In this embodiment, when the two locking rods 6 are correspondingly inserted into the multiple limit slots 3, the elastic buckle 82 is elastically connected to the locking piece 81, so that the two locking rods 6 are fixed, thereby limiting the excess bent part of the wiring harness body 1. By pressing the elastic buckle 82, the two locking rods 6 can be opened, so that the bent part of the wiring harness body 1 can be taken out, thereby realizing the adjustment of the length of the wiring harness body 1.

[0031] Specifically, the circumferential surface of the wiring harness body 1 is fixedly connected with a fixed sleeve 9 , one end of each of the two rotating clamping rods 4 is fixedly connected with a rotating ring 10 , and both rotating rings 10 are rotatably connected to the circumferential surface of the fixed sleeve 9 .

[0032] In this embodiment, the two rotating clamping rods 4 are rotatably connected to the surface of the wiring harness body 1 through two rotating rings 10 and two fixed sleeves 9. The fixed sleeves 9 are fixed on the surface of the wiring harness body 1, which can effectively prevent the two rotating rings 10 from damaging the wiring harness body 1 when rotating.

[0033] Specifically, the top ends of the two rotating levers 4 and the two middle levers 5 are provided with sliding grooves 11, the bottom ends of the two middle levers 5 and the two locking levers 6 are fixedly connected with sliders 12, and the four sliders 12 are respectively slidably connected in the four sliding grooves 11.

[0034] In this embodiment, when the two middle clamping rods 5 and the two locking clamping rods 6 are extended or retracted in length, the four sliders 12 slide in the four sliding grooves 11 respectively, so that the extension and retraction of the two middle clamping rods 5 and the two locking clamping rods 6 remain stable.

[0035] Specifically, the two locking levers 6 and the two rotating levers 4 are fixedly connected with magnets 13 , and the four magnets 13 correspond to each other.

[0036] In this embodiment, when the wiring harness body 1 does not need to be adjusted in length, the two locking rods 6 and the two middle rods 5 are respectively retracted toward the two rotating rods 4 to reduce their length. After retraction, the two magnets 13 on the two locking rods 6 are respectively magnetically connected to the two magnets 13 on the two rotating rods 4, so that the two locking rods 6, the two middle rods 5 and the two rotating rods 4 are fixed in the retracted state.

[0037] Working principle: When adjusting the length of the wiring harness body 1, the wiring harness body 1 is bent through multiple bending slots 2. The multiple limit slots 3 on the bent part of the wiring harness body 1 are located on the same straight line and correspond to the two rotating rods 4. The two middle rods 5 and the two locking rods 6 are telescopically adjusted according to the length of the bent part of the wiring harness body 1. By rotating the two rotating rods 4, the multiple slots 7 on the two rotating rods 4, the two middle rods 5 and the two locking rods 6 are respectively inserted into the multiple limit slots 3. At the same time, the elastic connection between the positioning piece 81 and the elastic buckle 82 fixes the two locking rods 6, and the two rotating rods 4 and the two middle rods 5 are also fixed, so that the bent part of the wiring harness body 1 is limited between the two rotating rods 4, the two middle rods 5 and the two locking rods 6, so that the wiring harness body 1 is maintained at the required length to achieve the purpose of adjustment.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
