Description

Technical area

The invention relates to an electrical connector, in particular an easily applicable, watertight electrical connector, which can be aligned quickly and ensures a low wear of the terminals.

State of the art

Although electrical connectors in a wide variety of designs are available on the market, most electrical connectors essentially consist of a male connector and a female connector which can be nested and thereby coupled together.

Depending on the application, a conventional electrical connector is provided with one or more electrical terminals which serve to transmit electrical energy and / or to transmit electrical signals. In order to increase the reliability and safety in the use of the electrical connector, the conventional electrical connectors are made to be tensile, dustproof and waterproof. The registered Taiwanese utility model TWM315444 discloses, for example, a connector for cables, in which the male connector is screwed by means of a nut on the receiving connection part. The registered Taiwanese utility model TWM328109 discloses an arrangement for quick positioning of a power connection, wherein the positioning with the arrangement according to the utility model TWM328109 can be performed faster than the fastening with a nut according to the utility model TWM315444. The registered Taiwanese utility model TWM395951 further discloses a terminal device which can be mounted in a housing of an electronic device to receive and protect the connecting parts connected to each other by a connector, the electrical connector according to the utility model TWM395951 obviously having a more complicated construction than the aforementioned conventional electrical connectors.

Electrical connectors for different applications or with different functions often have a slightly different structure. It is possible that an electrical connector for a particular function must have a more complex structure.
