Quick connecting type outdoor waterproof electric coupler

Abstract

The invention discloses a quick connecting type outdoor waterproof electric coupler which is composed of male a joint and a female joint, wherein the male joint and the female joint are in butt joint, the male joint is provided with a cylindrical bore in which the male terminal is arranged, and the female joint is provided with a cylindrical plug in which the female terminal is arranged. The quick connecting type outdoor waterproof electric coupler is characterized in that all male terminals and female terminals are all arranged on the peripheral direction of the same diameter, the connecting part of the female terminals is provided with a U-shaped structure, between the inner wall of the cylindrical bore and the outer edge of the cylindrical plug, one is provided with an L-shaped guide slot, the other is provided with a convex guide pillar, and the bottom surface of the cylindrical bore is provided with an end surface waterproof gasket. When be in connection, the convex guide pillar aims at an axial guide slot of the L-shaped guide slot to cause the cylindrical plug to be inserted into the cylindrical bore; meanwhile, the male terminal is inserted into accommodation space in front of the U-shaped opening of the female terminal; the end surface waterproof gasket forms an end surface waterproof seal between the cylindrical bore bottom surface and the cylindrical plug end surface; when the cylindrical plug rotates one phase angle relatively to the cylindrical bore, the convex guide pillar slides along the peripheral guide slot of the L-shaped guide slot; meanwhile, the male terminal is inserted into the U-shaped structure from the side direction of the female terminal to form the electric connection.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a quick-connect outdoor waterproof electrical connector. This electrical connector is especially suitable for use in outdoor places, and has the characteristics of quick connection, waterproof, corrosion resistance, ultraviolet resistance and moisture resistance. Background technique [0002] Electrical connectors are widely used as connecting devices for power supply or electrical signals in electronic equipment, electronic instruments, and network communications. When electrical connectors are used in outdoor places, due to environmental influences, there are higher requirements for their connection performance and functions. For example, in addition to good electrical connection performance, they must also have functions such as waterproof, corrosion resistance, UV resistance, and moisture resistance. Therefore, how to design this type of electrical connector directly affects the ef...

AI Technical Summary

Problems solved by technology

This outdoor electrical connector has the following deficiencies: 1. The male and female terminals adopt a hole shaft in-line connection structure, because the female terminal is in point contact with the outer edge of the male end by the shrapnel, and the metal fatigue is prone to occur due to the shrapnel , leading to a decrease in the reliability of the contact between the terminals, especially in the environment where the outdoor temperature and humidity change greatly, poor contact is prone to occur

2. After the male connector and the female connector are mated, it is necessary to repeatedly rotate the threaded sleeve to tighten the two, which makes the assembly cumbersome and brings inconvenience to the construction operation

3. The waterproof and moisture-proof sealing performance is not good
