Description

Wire stress relief structure

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

Electronic devices are mostly connected by cables for power or signal transmission. In addition, because the cable where the cable is connected to the electronic device is often subjected to a large torsional stress when the electronic device is used or moved, the cable is damaged and the service life is shortened.

Furthermore, at present, the electronic device is usually provided with a strain relief (Strain Relief, SR) function at the place where the electronic device is connected to the cable. In this wire frame structure, a covering sleeve is directly formed at the place where the electronic device or the connector is connected with the cable, so as to eliminate or reduce the stress at the connection place between the connector and the cable. However, the existing wire frame structure still produces stress concentration at the end of the covering sleeve, which easily causes the cable to break or be damaged.

In view of this, the inventor of the present invention aimed at the above-mentioned prior art, devoted himself to research and combined with the application of theories, and tried 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 tied to a plurality of ridges on the outer edge of the wire, so as to eliminate or reduce the stress at the connection between the connector and the cable.

In order to achieve the above purpose, the present invention is a wire stress relief structure, which includes a lead base, a wire, a supporting element and an insulating sleeve. The lead socket includes an insulating body and a lead element arranged in the insulating body. The wire passes through the insulating body and is electrically connected to the conducting element. The supporting element includes a plurality of ridges with spacer rings arranged on the outer edge of the wire, and the ridges respectively extend along the wire toward a direction away from the insulating body. The insulating sleeve covers the supporting element and extends along the wire direction.

Compared with the conventional one, the wire rod stress relief structure of the present invention is provided with supporting elements on the outer edge of the wires. The supporting elements are connected to the conductive sockets and include a plurality of ridges arranged at intervals and surrounding them. The ridges move away from the insulation along the wires. The direction of the main body extends; accordingly, when a force is applied between the guide seat and the wire, the stress can extend along the ridge and gradually disperse, thereby eliminating the phenomenon of stress concentration and prolonging the service life of the wire.
