Description

Technical Field

[0001] The utility model belongs to the technical field of encoder wire harnesses, and in particular relates to an encoder wire harness with a bending-resistant structure. Background Art

[0002] An encoder wiring harness is an electrical wiring harness primarily used to connect encoders to controllers (or readouts) for signal transmission. An encoder is a sensor used to measure rotational, displacement, or linear position, converting this position information into a digital signal. Encoder wiring harnesses play an irreplaceable role in industrial automation and precision equipment. They not only ensure stable signal transmission between the encoder and controller, but also provide accurate position information, improving system performance and stability. Therefore, when selecting and maintaining encoder wiring harnesses, special attention must be paid to their quality and reliability.

[0003] In practical applications, encoder wiring harnesses inevitably develop kinks in certain areas due to limitations in their routing and routing. If these kinks persist and are not properly addressed, they will gradually negatively impact the encoder harness's internal structure. Specifically, prolonged kinking can cause uneven stress on the wire cores within the encoder harness, leading to wear and tear, breakage, and decreased signal transmission performance. These internal damages can not only weaken the harness's mechanical strength but also cause signal distortion or interruption, ultimately severely impacting the encoder harness's performance and potentially even leading to performance degradation or failure of the entire system. Utility Model Content

[0004] The purpose of the present utility model is to provide an encoder wiring harness with a bend-resistant structure, which aims to solve the problem that the encoder wiring harness will inevitably form a bending state in certain areas due to the limitations of its laying and routing paths in actual applications. If this bending state persists and is not properly handled, it will gradually have an adverse effect on the internal structure of the encoder wiring harness. Specifically, long-term bending will cause the wire core inside the encoder wiring harness to bear uneven stress, which will cause the wire core to wear, break, or reduce the signal transmission performance. These internal damages may not only weaken the mechanical strength of the wiring harness, but may also cause signal distortion or interruption, which will ultimately seriously affect the normal use of the encoder wiring harness and may even cause performance degradation or failure of the entire system.

[0005] To achieve the above object, the present invention provides the following technical solution: an encoder wiring harness with a bending-resistant structure, comprising an encoder wiring harness, a spring sleeved on the outer wall of the wiring harness, and a first sheath provided on one side of the outer wall of the spring;

[0006] A second sheath is provided on one side of the opening of the first sheath. The first sheath and the second sheath are wrapped around the outer wall of the spring. Through holes are provided on the outer walls of the first sheath and the second sheath at equal intervals.

[0007] To allow the bayonet to mate with the assembled horizontal and side bars, a preferred embodiment of the encoder wiring harness with a bend-resistant structure of the present invention includes a bayonet on the outer wall of the open end of the first sheath, with the side profile of the bayonet being a T-shaped structure. A horizontal bar is fixedly mounted on the outer wall of the open end of the second sheath, and a side bar is fixedly mounted on each of the outer walls of the horizontal bar away from the end that mates with the second sheath.

[0008] In order to ensure that the horizontal bar and the side bar can maintain a relatively fixed connection relationship after docking with the bayonet, as an encoder wiring harness with a bending-resistant structure of the utility model, the second sheath is preferably installed on one side of the first sheath through an interference connection between the horizontal bar and the side bar and the bayonet.

[0009] In order to ensure that the first sheath and the second sheath can maintain the insulation structure after being installed on the outer wall of the encoder wiring harness, as a preferred encoder wiring harness with a bending-resistant structure of the present invention, the first sheath and the second sheath are both semicircular structures, and the first sheath and the second sheath are both made of insulating hard rubber material.

[0010] In order to enhance the bending resistance of the encoder harness when it is bent, as an encoder harness with a bending-resistant structure preferred in the present invention, the spring is made of hard insulating rubber, and the maximum diameter of the spring is adapted to the inner diameter of the first sheath and the second sheath after docking.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When in use, first wrap the spring around the wire body of the encoder wiring harness. After the spring is wound, dock the first sheath and the second sheath on the outer wall of the ring, and fix them to the outer wall of the spring through the docking between the bayonet and the horizontal bar and the side bar. In this way, when the encoder wiring harness is bent during use, the spring, the first sheath and the second sheath will bend synchronously. At this time, the elastic potential energy of the spring, the first sheath and the second sheath will strengthen the bent encoder wiring harness, so that the above structure can enhance the bending resistance of the encoder wiring harness during use.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5 The utility model provides the following technical solutions: an encoder wiring harness with a bending-resistant structure, comprising an encoder wiring harness 1, a spring 2 being sleeved on the outer wall of the wiring harness 1, and a first sheath 3 being provided on one side of the outer wall of the spring 2;

[0022] A second sheath 4 is provided on the opening side of the first sheath 3 . The first sheath 3 and the second sheath 4 are wrapped around the outer wall of the spring 2 . Through holes 5 are provided on the outer walls of the first sheath 3 and the second sheath 4 at equal intervals.

[0023] Preferably, a bayonet 301 is provided on the outer wall of the open end of the first sheath 3, and the side profile of the bayonet 301 is T-shaped. A horizontal bar 401 is fixedly mounted on the outer wall of the open end of the second sheath 4, and a side bar 402 is fixedly mounted on the outer walls of both sides of the horizontal bar 401 away from the end that interfaces with the second sheath 4.

[0024] During specific use, the horizontal bar 401 and the side bar 402 are assembled to form a T-shaped card strip. The T-shaped card strip is made of hard rubber as a whole, and the size of the T-shaped card strip is larger than the size of the bayonet 301. During installation, one side opening of the bayonet 301 is opened so that the T-shaped card strip can be installed into the interior of the bayonet 301, and the T-shaped card strip will maintain a relatively fixed connection structure with the bayonet 301.

[0025] Preferably, the second sheath 4 is mounted on one side of the first sheath 3 via an interference fit between the horizontal bar 401 and the side bar 402 and the bayonet 301. Both the first sheath 3 and the second sheath 4 have a semicircular structure and are made of insulating hard rubber. The spring 2 is made of hard insulating rubber, and its maximum diameter matches the inner diameter of the first and second sheaths 3 and 4 after they are joined.

[0026] When in use, the spring 2 is wound around the wire body of the encoder harness 1, and then the first sheath 3 and the second sheath 4 are wrapped around the outer wall of the spring 2. When installing, the horizontal bar 401 and the side bar 402 on one side of the second sheath 4 are inserted into the inside of the bayonet 301 from the opening on one side of the bayonet 301. Finally, the first sheath 3 and the second sheath 4 can be assembled together;

[0027] Through the above structure, the spring 2, the first sheath 3 and the second sheath 4 can be effectively installed on the wire body of the encoder wire harness 1. When the wire body of the encoder wire harness 1 is bent, the wire body of the encoder wire harness 1 will also drive the spring 2, the first sheath 3 and the second sheath 4 to bend. Since the spring 2, the first sheath 3 and the second sheath 4 themselves have good bending resistance, the encoder wire harness 1 can enhance its own bending resistance through the spring 2, the first sheath 3 and the second sheath 4.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
