[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0022] In the description of the utility model, it needs to be understood that the orientation or position relationship indicated by terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawing, and is only for the convenience of describing the utility model and simplifying the description, and is not indicative or implied that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, so it cannot be understood as a limitation on the utility model.
[0023] Embodiment:
[0024] Refer to Figures 1-4This utility model provides a connecting wire structure, including a connector 1. The material of the connector 1 is thermoplastic elastomer, thermoplastic polyurethane, rubber, nylon, or polyamide. The axial cross-sectional shape of the connector 1 is circular or triangular, or even elliptical. A mounting hole 2 is provided along the axial direction of the connector 1 for threading the connecting wire. It also includes an annular transition portion, wherein the annular transition portion includes a first annular end coupled to the connector 1 and a second annular end coupled to the mounting hole 2. The connecting surface 3 from the first annular end to the second annular end extends toward the center of the connector 1. The radial cross-sectional shape of the connecting surface 3 is a concave arc surface or a convex arc surface. In practice, the convex arc surface has a better mitigation effect.
[0025] Specifically, during use, the end of connector 1 without the connecting surface 3 needs to be fixed to the terminal. Then, the wire is passed through the mounting hole 2 and connected to the terminal. When the wire is bent, connector 1 can buffer the shearing force exerted by the wire on the terminal, while the connecting surface 3 can buffer the pressure exerted by connector 1 on the wire. Furthermore, multiple wires can be installed in the same mounting hole 2 at the same time, which ensures the overall aesthetics and reduces production costs.
[0026] The radial section of the aforementioned connecting surface 3 is projected onto the axis of the connector 1 with a length of 3mm-5mm. Its depth is mainly adjusted according to the diameter of the wire. The thicker the wire, the longer the projected length; the thinner the wire, the shorter the projected length. In actual production and use, it has been found that when the projected length of the connecting surface 3 is much greater than 5mm, the transition effect remains basically unchanged.
[0027] The outer wall of the aforementioned connector 1 is provided with an annular buffer groove 4.
[0028] Specifically, when the wire is subjected to a large bending force, the connector 1 itself can also bend to achieve the effect of buffering the force, and the design of the annular buffer groove 4 will make the buffering effect of the connector 1 even better.
[0029] The outer wall of the connector 1 is fixedly fitted with a protective layer. The hardness of the protective layer is greater than that of the connector 1. When the material of the connector 1 is thermoplastic elastomer and the hardness is Shore A 70, then the material of the protective layer is Shore A 90, and so on. Thus, the harder protective layer can protect the connector 1 and improve its service life.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
