The diagrams show preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0024] The present invention will be described more specifically by way of example with reference to the accompanying drawings in the following paragraphs. The advantages and features of the present invention will become clearer as described in the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0025] Example 1

[0026] Please refer to Figures 1-2 This embodiment discloses a fastening device for automotive corner signal harnesses, comprising:

[0027] Fastener 2 is installed on the vehicle steering shaft;

[0028] Cable 1 passes through the fastener 2 and is electrically connected to connector 3.

[0029] This utility model discloses a fastening structure for a car corner signal harness. By setting a fastener 2 on the car steering shaft and passing the cable 1 through the fastener 2, and then achieving electrical connection through a connector 3, the structure of the entire harness assembly is simple, easy to install, and can be stably fixed on the car steering shaft, improving the firmness of the harness fixation and simplifying the installation steps.

[0030] In this embodiment, please continue to refer to Figure 1 The fastener 2 includes: a fastener body; a positioning hole 5 disposed inside the fastener body, through which the cable 1 passes; and a positioning notch 6 disposed inside the fastener body, which engages with a corresponding protrusion on the vehicle steering shaft.

[0031] In this embodiment, the fastener 2 passes the cable 1 through the positioning hole 5, which fixes and protects the cable 1, preventing wear or displacement of the cable 1 during use. It also acts as a stress buffer for the cable 1, extending its service life. At the same time, the integrated design of the fastener 2 makes the entire wire harness assembly compact, easy to assemble, and improves production and maintenance efficiency.

[0032] Specifically, the positioning hole 5 is provided through the axial direction of the fastener body. The connector 3 is electrically connected to the fastener body after passing through the positioning hole 5.

[0033] Specifically, the positioning hole 5 is at least one of a circle, a rectangle, and an ellipse. A circle is preferred, as it matches the shape of the connection terminal of the cable 1. The positioning holes 5 are arranged equidistantly in the axial direction. The number of positioning holes 5 is not specifically limited here; it can be 5, 6, or 7, etc. It is understood that each cable 1 requires one positioning hole 5 for fixing and guiding; therefore, the number of positioning holes 5 corresponds to the number of cables 1 that need to be fixed. Furthermore, the cross-sectional size of the positioning hole 5 is not specifically limited here; it only needs to be large enough for the cable 1 to pass through.

[0034] For further details, please refer to... Figure 2 The positioning notch 6 extends along the axial direction of the fastener body.

[0035] The positioning notch 6 is located inside the fastener body. The positioning notch 6 cooperates with the protrusion on the vehicle steering shaft. Through the concave-convex cooperation, when the fastener 2 is fitted onto the vehicle steering shaft, the protrusion on the vehicle steering shaft is embedded in the positioning notch 6, thereby achieving circumferential positioning of the fastener 2 on the vehicle steering shaft and preventing circumferential rotation of the fastener 2 during use, thus ensuring that the wiring harness assembly always remains in the correct installation position.

[0036] Through the above structural design, one end of cable 1 is electrically connected to connector 3, and the other end can pass through the positioning hole 5 in fastener 2 and connect to the signal detection device on the vehicle's steering shaft. When the vehicle's steering shaft rotates, the signal detection device collects the steering angle signal, transmits the electrical signal to connector 3 through cable 1, and then transmits it to the vehicle's control system, thereby realizing real-time monitoring and control of the steering angle.

[0037] Furthermore, in this embodiment, the fastener body is also provided with a sealing groove 7, which is arranged around the fastener body in the circumferential direction.

[0038] Specifically, the sealing groove 7 is an annular groove that surrounds the fastener body circumferentially. The depth of the sealing groove 7 (depth refers to the distance from the outer surface of the fastener body to the inward recess) is not specifically limited, but is determined by the circumference of the fastener body. For example, the depth of the sealing groove 7 is 2-3 mm.

[0039] Specifically, a sealing ring is provided inside the sealing groove 7. When the fastener 2 is installed on the automotive steering shaft, the sealing ring fits tightly against the surface of the steering shaft, forming a reliable sealing structure to prevent water, dust, and other foreign objects from entering, thereby protecting the internal cable 1 and improving the reliability of the wiring harness assembly. In this embodiment, the fastener 2 is made of IP67-rated NBR (nitrile rubber), which has excellent waterproof sealing performance, prevents dust from entering, and can be immersed in water at a depth of 1 meter for 30 minutes without leakage. It also has oil resistance, ozone resistance, and aging resistance, ensuring long-term reliable dust and water protection for the wiring harness in the complex environment of the automotive steering system. Of course, those skilled in the art can also choose other materials that can achieve the above effects.

[0040] Furthermore, in this embodiment, the fastener 2 is manufactured by injection molding, which molds it into a single component and then assembles it onto the wire harness. The injection molding process is simple, can be completed in one step, has high production efficiency, and the fastener 2 is easy to assemble, effectively reducing production costs.

[0041] In addition, in this embodiment, the two ends of the cable 1 are respectively provided with connection terminals.

[0042] The connector 3 is fixed to one of the connecting terminals. The connector 3 includes a connector 3 terminal, and one of the connecting terminals of the cable 1 is crimped and fixed to the connector 3 terminal. It can be understood that crimping refers to mechanically deforming and connecting the metal wire at the end of the cable 1 to the connector 3 terminal using a special crimping tool, so that the wire and the terminal are tightly joined together to form a reliable electrical and mechanical connection.

[0043] Furthermore, one end of the other connection terminal of the cable 1 adopts a protective cap structure. The specific connection method is as follows: First, the insulation layer of the cable 1 end is stripped to expose the wire. Then, the wire is soldered or crimped to the wiring terminal of the steering angle sensor. Finally, the protective cap 4 is fitted onto the end of the cable 1 and forms a sealed connection with the end of the sensor. This connection method not only ensures a reliable electrical connection, but also prevents moisture, dust, and other external impurities from entering through the sealing effect of the protective cap 4, protecting the electrical connection point and improving the reliability and service life of the wiring harness assembly during use.

The advantages of the fastening device for the vehicle corner signal harness disclosed in Embodiment 1 are also present in the new energy vehicle provided in this embodiment, and will not be repeated here.

[0046] Specifically, connector 3 of the vehicle steering angle signal harness fastening structure is connected to the signal acquisition device. When the vehicle's steering shaft rotates, the signal detection device acquires the steering angle signal, transmits the electrical signal to connector 3 via cable 1, and then transmits it to the vehicle's control system, thereby realizing real-time monitoring and control of the steering angle.

[0047] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
