Five-pole waterproof electrical connector

Abstract

The invention relates to a five-pole waterproof electrical connector which comprises an upper seat and a lower seat, wherein the upper seat includes a shell. One side of the shell is provided with a first signal terminal, a second signal terminal, an L pole terminal, an N pole terminal and a ground connection terminal while the other side of the shell is provided with a cavity of the upper seat with a center sleeve stretching out of it. A center cavity is arranged inside the center sleeve while a signal conducting pillar is mounted inside the center cavity. The signal conducting pillar is made up of a first signal touch-sensing terminal and a second signal touch-sensing terminal, wherein the first signal touch-sensing terminal and the second signal touch-sensing terminal are isolated from each other. The center sleeve is provided with the L pole terminal and the N terminal. The inner sidewall of the cavity of the upper seat is sleeved with a ground touch-sensing terminal which is connected with the ground connection terminal. The connector has the advantages of a simple and reasonable structure, small size as well as a low manufacturing cost, and meanwhile function settings of connecting two independent signals can be accomplished.

Description

technical field [0001] The invention relates to the technical field of household appliance accessories, in particular to a waterproof five-pole electrical connector. Background technique [0002] At present, electrical connectors for household appliances generally include an upper electrical connector base and an electrical connector lower base, which are plugged and mated with each other to realize the electrical connection between the electrical appliance and the power supply. Therefore, electrical connectors are widely used in household appliances such as electric kettles and electric heating pots. With the improvement of people's living standards, the functional requirements for household appliances have also increased. Therefore, in addition to meeting the power supply or temperature control functions, electrical connectors also need to have other signal or detection functions at the same time. Therefore, it is necessary to increase the signal Terminals, and there are ...

Problems solved by technology

With the improvement of people's living standards, the functional requirements for household appliances have also increased. Therefore, in addition to meeting the power supply or temperature control functions, electrical connectors also need to have other signal or detection functions at the same time. Therefore, it is necessary to increase the signal Terminals, and there are few electrical connectors with five poles (five terminals, including L pole, N pole, ground pole and two signal poles) on the market. Generally, multiple concentric ring electrodes are used for combination , which has high manufacturing cost and large volume, such as the literature disclosed in Chinese patent ZL 201520672947.7
