Description

Technical Field

[0001] The utility model relates to the technical field of wiring harness terminals, in particular to an anti-rotation wiring harness terminal. Background Art

[0002] Wire harness terminals are an integral part of electrical connections and are widely used in a variety of electrical and electronic equipment. Traditional wire harness terminals are typically made of metal and are primarily used to secure wires or cables and ensure the safety and reliability of electrical connections. A typical wire harness terminal consists of a clamp for holding the wires and a securing plate with a connection hole. During installation, the plate must be tightly fitted to the mounting location and secured with a bolt that passes through the connection hole and screws into the mounting location. However, in practice, there is a problem: when the bolt is tightened against the plate, the torque from the tightening or equipment vibration can cause the plate to rotate relative to the mounting location, causing the entire wire harness terminal to shift relative to its fixed position. This shift not only affects the stability of the wire harness terminal itself and the quality of the electrical connection, but can also prevent subsequent electronic components from being installed smoothly, increasing assembly difficulty and posing potential safety risks. Summary of the Invention

[0003] Purpose of the present invention: In order to overcome the defects of the prior art, the present invention provides a wiring harness terminal with an anti-rotation function, which solves the problem that the wiring harness terminal is prone to rotation.

[0004] The technical solution of the utility model comprises a clamping body and a connecting piece, wherein a connecting hole is opened in the connecting piece, a convex arm extends outward from the outer periphery of the connecting piece, and the convex arm is integrally connected to the connecting piece.

[0005] By adopting the above technical solution, the protruding arm fits into the groove shape of the fixed position, so that the protruding arm has a limiting function, which can effectively prevent the connecting piece from rotating when tightening the bolt, ensuring the stability of the wiring harness terminal in the fixed position, reducing the safety hazards caused by poor connection, and can guide the wiring harness terminal to align with the fixed position, making installation simpler and faster.

[0006] In a possible design, the installation direction of the protruding arm is eccentrically arranged with respect to the center of the connecting hole.

[0007] With the above design, the eccentric arrangement of the protruding arm can generate a torque in a different direction when the bolt is tightened, thereby more effectively preventing the connecting piece from rotating with the bolt and ensuring the stable position of the wiring harness terminal in the installed state.

[0008] In one possible design, the protruding arm is in the shape of a rounded rectangle.

[0009] With the above design, the rounded rectangular shape can provide a larger contact area, which helps to provide sufficient friction when the bolt is tightened to resist the tendency to rotate. Moreover, the rounded shape can avoid stress concentration, improve the structural strength of the protruding arm, and make it less likely to be damaged when subjected to torque.

[0010] In a possible design, there is one protruding arm.

[0011] With the above design, the single protruding arm provides a clear anti-rotation point, which helps to keep the position of the wiring harness terminal stable and is easier to align during installation, helping to quickly position the wiring harness terminal.

[0012] In a possible design, the connecting piece is bent relative to the clip body.

[0013] With the above design, the bent wiring harness terminal can form a good fit with the fixed position of the corner shape, while increasing the limiting contact position to facilitate positioning and installation.

[0014] In one possible design, the clamp body includes a conductive clamp portion and a fixed clamp portion, wherein the conductive clamp portion is closer to the connecting piece than the fixed clamp portion, the conductive clamp portion encloses and clamps the conductor of the wire, and the fixed clamp portion encloses and clamps the insulation layer of the wire.

[0015] With the above design, the connecting clamp is directly clamped on the conductor of the wire, which can ensure good electrical contact and improve the reliability and stability of the electrical connection; the fixing clamp is clamped on the insulation layer of the wire, which can prevent the wire from sliding inside the wire harness terminal and ensure the stable fixation of the wire.

[0019] like Figure 1 、 Figure 2The illustrated anti-rotation wiring harness terminal comprises a clamping body and a connecting plate. The clamping body is used to clamp the wire, and the connecting plate has a connecting hole for connecting to a fixed position. A protruding arm extends outward from the outer periphery of the connecting plate and is integrally connected to the connecting plate, providing an anti-rotation structure to prevent the connecting plate from rotating when the bolt is tightened. The protruding arm and the connecting plate are integrally formed, which helps ensure sufficient strength and stability between the protruding arm and the connecting plate, effectively resisting vibration or torque generated when the connecting plate is tightened. During use, the connecting plate is aligned with the fixed position, and the connecting hole is coaxially arranged with the screw hole of the fixed position. The protruding arm fits into the groove of the fixed position, and the bolt is passed through the connecting hole and gradually screwed into the fixed position until the bolt is tightly attached to the surface of the connecting plate and cannot rotate. The connecting plate is then fixed in place. Compared with the existing technology, this ensures that the connecting plate remains stationary during the bolt tightening process, compensating for the existing problem of the connecting plate rotating with the bolt and vibrating. It also ensures the stability of the connecting plate position and facilitates the subsequent installation of electronic components.

[0020] The mounting direction of the lug is eccentric to the center of the connecting hole. The mounting direction of the lug corresponds to the central axis of the lug, and the center of the connecting hole corresponds to the center of the circle. The eccentricity means that the center of the connecting hole is not located on the central axis of the lug. This eccentric arrangement of the lug generates a torque in a different direction when the bolt is tightened, effectively preventing the connector from rotating with the bolt and ensuring a stable position of the wiring harness terminal when installed.

[0021] There is only one protruding arm, which is a rounded rectangular shape, making it asymmetrical overall. The position of the protruding arm is more clearly defined, making it easier to align during installation and facilitating the quick positioning and installation of the connecting piece.

[0022] The connecting piece is bent approximately 90 degrees relative to the clamp body. The clamp body includes a conducting clamp portion and a fixing clamp portion. The conducting clamp portion is closer to the connecting piece than the fixing clamp portion. The conducting clamp portion encloses and clamps the conductor end of the wire, and the fixing clamp portion encloses and clamps the colloidal insulation layer of the wire. By designing the conducting clamp portion and the fixing clamp portion separately, their respective functions can be optimized. The conducting clamp portion can ensure the firmness of the connection by welding the conductor end and increasing the clamping force, while the fixing clamp portion provides appropriate clamping force to the colloidal insulation layer to reduce mechanical damage to the wire. In this way, the clamp body can ensure that the conductor and insulation layer of the wire are properly fixed, improve the flexibility of wire fixation, and make the wiring harness terminal applicable to various types of wires, thereby improving its versatility and adaptability.
