Description

Wire stress relief structure

The present invention relates to a wire outlet structure, in particular to a wire stress relief structure.

Most electronic devices use cable connections for power or signal transmission. In addition, since the cables where the cables are connected to the electronic equipment are often subjected to large torsional stress when the electronic device is used or moved, the cables are damaged and their service life is shortened.

Furthermore, current electronic devices are usually equipped with a wire stop structure with a stress relief (Strain Relief, SR) function where the cable is connected. This wire stop structure directly forms a covering sleeve where the electronic device or connector is connected to the cable, thereby eliminating or reducing the stress at the connection between the connector and the cable. However, the existing wire stop structure still produces stress concentration at the connection end of the covering sleeve, which may easily cause the cable to break or be damaged.

In view of this, the inventor of the present invention devoted himself to research on the above-mentioned existing technology and cooperated with the application of academic theory to try his best to solve the above-mentioned problems, which became the goal of the improvement of the present invention.

One object of the present invention is to provide a wire stress relief structure, which is composed of a plurality of ridges on the outer edge surface of the conductor, so as to eliminate or reduce the stress at the connection between the connector and the cable.

In order to achieve the above object, the present invention is a wire stress relief structure, which includes a conductive base, a conductor, a supporting element and an insulating sleeve. The conductive base includes an insulating body and conductive elements arranged in the insulating body. The wires pass through the insulating body and are electrically connected to the conductive components. The support element includes a plurality of ridges arranged on the outer edge of the conductor in a spaced ring, and the ridges respectively extend along the conductor in a direction away from the insulating body. The insulating sleeve covers the support element and extends along the direction of the conductor.

Compared with the conventional ones, the wire stress relief structure of the present invention is provided with a support element on the outer edge of the conductor. The support element is connected to the conductor base and includes a plurality of spaced and surrounding ridges. The ridges move along the conductor away from the insulation. The direction of the main body extends; accordingly, when force is applied between the conductor base and the wire, the stress can extend along the ridge and gradually disperse, thereby eliminating stress concentration and extending the service life of the wire.
