Description

Technical Field

[0001] This utility model relates to the field of servo encoder cables, specifically a breakage-resistant servo encoder cable. Background Technology

[0002] Servo encoder cables, also known as feedback cables or servo encoder wires, are an essential component connecting the servo motor encoder and the controller. By sensing changes in the motor rotor's position, the servo encoder cable transmits this position information to the motor controller, enabling precise position control. The servo encoder cable can also act as a motor speed sensor, sensing the rotor's rotational speed and transmitting real-time speed information to the controller, thus aiding in speed control.

[0003] However, in daily use, due to the different position settings between the servo motor and the encoder, when the length is insufficient, it is usually pulled and dragged multiple times manually. Repeated pulling can cause the servo encoder wire to be torn or broken, resulting in poor anti-breakage ability. Moreover, during operation, the operator may step on it, which can cause the internal wire core to be damaged by pressure. This makes the servo encoder wire easy to deform and easily bent and damaged by external pressure, resulting in poor pressure resistance. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a break-resistant servo encoder cable, which can effectively solve the technical problems of poor break-resistant capability and poor pressure resistance of existing servo encoder cables.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a breakage-resistant servo encoder cable, including a cable body, one end of which is provided with a servo terminal, and the other end of which is provided with a motor terminal. The cable body includes an outer sheath and an anti-breakage strip. The outer sheath wraps around the anti-breakage strip. The outer sheath includes an insulating layer and a sponge pad layer. The insulating layer and the sponge pad layer are bonded together. The insulating layer wraps around the sponge pad layer. The surface of the anti-breakage strip has several locking grooves. The locking grooves are equidistantly arranged along the circumference of the anti-breakage strip. Multiple first wire cores are sleeved inside the locking grooves. The surfaces of the multiple first wire cores are respectively in contact with the inner wall of the anti-breakage strip. Several metal wires are filled between the sponge pad layer and the anti-breakage strip. The metal wires extend along the direction of the anti-breakage strip. The interior of the anti-breakage strip is provided with a hollow cylindrical groove. A second wire core is sleeved inside the cylindrical groove. The surface of the second wire core is in contact with the inner wall of the anti-breakage strip.

[0006] Furthermore, the motor terminal has several square openings arranged at equal intervals inside, and snap-fit ​​blocks are provided on both sides of the motor terminal to achieve snap-fit ​​and fixation of the motor terminal.

[0007] Furthermore, U-shaped grooves are provided on both sides of the servo terminal, and the U-shaped grooves are symmetrically distributed.

[0008] Furthermore, a connection port is fixedly provided inside the servo terminal, and a long screw is movably provided inside the servo terminal, the long screw passing through the servo terminal and extending to the outside of the servo terminal.

[0009] Furthermore, a fixing block is provided between the cable and the servo terminal, and the cable passes through the fixing block to connect to the servo terminal.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a breakage-resistant servo encoder cable. By opening a locking groove and a cylindrical groove on the breakage-resistant strip, the first wire core can be fitted inside the locking groove, and the second wire core can be fitted inside the cylindrical groove. This allows the wire cores to be evenly distributed and mutually supported, effectively enhancing the cable's breakage resistance. Furthermore, the breakage-resistant strip can protect the first and second wire cores. The addition of metal wires further improves the cable's strength, and the addition of a sponge pad allows it to contract under pressure, achieving a protective and buffering effect. This increases the elasticity of the servo encoder cable, thereby greatly improving its overall compressive strength. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] like Figures 1-4 As shown, a breakage-resistant servo encoder cable includes a cable body 1. One end of the cable body 1 is provided with a servo connector 2, and the other end of the cable body 1 is provided with a motor connector 3. The cable body 1 includes an outer sheath and a breakage-resistant strip 12, wherein the breakage-resistant strip 12 can be made of rubber. The outer sheath wraps around the breakage-resistant strip 12. The outer sheath includes an insulating layer 10 and a sponge pad layer 11. The insulating layer 10 and the sponge pad layer 11 are bonded together. The insulating layer 10 wraps around the sponge pad layer 11. The surface of the breakage-resistant strip 12 has a plurality of engaging grooves 16, which are equidistantly arranged along the circumference of the breakage-resistant strip 12. The inner sleeve contains multiple first core wires 13, the surfaces of which are respectively in contact with the inner wall of the anti-breakage strip 12. The space between the sponge pad layer 11 and the anti-breakage strip 12 is filled with several metal wires 15, which extend along the direction of the anti-breakage strip 12. The anti-breakage strip 12 has a hollow cylindrical groove 17 inside, and a second core wire 14 is sleeved inside the cylindrical groove 17. The surface of the second core wire 14 is in contact with the inner wall of the anti-breakage strip 12. The outer sheath is composed of an insulating layer 10 and a sponge pad layer 11, providing double protection for the internal core wires. The sponge pad layer 11 provides additional cushioning and protection, reducing damage caused by external impact or compression.

[0019] The motor terminal 3 has several equally spaced square openings 8 inside. Both sides of the motor terminal 3 have locking blocks 9 for securing the motor terminal 3, ensuring a more stable connection of the encoder cable to the motor and reducing the risk of loosening or detachment. Both sides of the servo terminal 2 have U-shaped grooves 7 arranged symmetrically. The servo terminal 2 has a fixed connection port 5 inside and a movable long screw 6 inside, which penetrates the servo terminal 2 and extends to its exterior. A fixing block 4 connects the cable 1 to the servo terminal 2, allowing the cable 1 to pass through the fixing block 4 and connect to the servo terminal 2, effectively strengthening the connection between the cable 1 and the terminal and making the connection between the servo terminal 2 and the cable 1 more secure.

[0020] This embodiment of a breakage-resistant servo encoder cable utilizes a locking groove 16 and a cylindrical groove 17 on the breakage-resistant strip 12. This allows the first wire core 13 to be fitted inside the locking groove 16 and the second wire core 14 to be fitted inside the cylindrical groove 17, ensuring even distribution and mutual support of the wire cores. This effectively enhances the tensile and breakage resistance of the cable body 1. The breakage-resistant strip 12 also protects the first and second wire cores 13 and 14. The addition of a metal wire 15 further improves the strength of the cable body 1. The addition of a sponge pad 11 allows the cable to contract under pressure, providing a buffering effect and increasing the elasticity of the servo encoder cable, thereby significantly improving its overall compressive strength. The cable body 1 of this breakage-resistant servo encoder cable can be manufactured using existing wrapping and other processes, which will not be described in detail here.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
