Description

Electrical connection device

The electrical connection device is used to provide electrical connection between two electronic components or two cable wires, and is widely used in various fields. For the purpose of achieving its electrical connection, a conductive line is provided in the electrical connection device, and the conductive line must be able to be stably connected to the device or line to be connected.

The electrical connection device can generally be divided into an electrical connection device for indoor use and an electrical connection device for outdoor use. Electrical connection devices for outdoor use are generally required to have a waterproof effect to prevent water from penetrating therein and causing short circuits or deterioration of electrical connection quality, such as electrical connections between cable lines. In order to achieve the effect of waterproofing, conventional techniques use a resilient envelope around the entire electrical connector to prevent water from penetrating therein. However, the assembly steps and processes of such electrical connectors are cumbersome.

However, such electrical connectors have the advantage of being quick to assemble and easy to use.

Some electronic devices, such as LED lighting devices, may be used indoors or outdoors. The electrical connectors between such electronic devices must combine the advantages of both waterproof and quick assembly. Therefore, there is still a need for an electrical connector that can achieve the above functions.
