Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary connection equipment for electric wires and cables, in particular to a connector with a waterproof cover and a power supply device. Background Art

[0002] The connectors of general power transmission equipment, electrical products and the pins of electrical appliances are called plugs, and household AC power plugs and sockets are collectively called connectors, including male plugs with rod-shaped or copper plate-shaped protrusions, and female plugs that are physically inserted into slots or holes.

[0003] Since power transmission equipment such as street lights are often used outdoors, and usually a single power supply supplies power to multiple identical loads, their operating voltages vary, some are extremely low, some are extremely high and can even reach hundreds of kilovolts. Therefore, the insulation quality of their connectors is a key factor in determining work safety and product life. Outdoors, it often rains, snows and other weather conditions, and the humidity is high. A damp connector not only has poor insulation performance and leakage, but also affects the performance of the product itself.

[0004] Therefore, the connector needs to be well protected from water, whether it is during normal operation or when the male and female plugs are not used together. Since the male and female plugs of the connector are generally integrated in two different modules or modules in advance, there are extra male plugs that are not used during transportation, maintenance, or outdoor wiring of these two different modules and modules. In order to prevent the intrusion of water or dust, it is often necessary to provide waterproof protection for the male and female plugs to prevent moisture from entering and causing damage to the modules or modules. However, in the current industrial waterproof connector, regarding the waterproof structure, only the waterproof cover can provide waterproof protection for the male or female plug separately, and the male and female plugs in paired use can be well protected from water. In addition, the existing male and female plugs have poor waterproof performance and cannot meet the use requirements under special conditions, which brings inconvenience to people's use.

[0005] Therefore, the present application provides a connector with a waterproof cover, which not only has good waterproof performance, but also includes a splitter, which can meet the application scenario requirements of a single power supply to multiple loads. Utility Model Content

[0036] Since power transmission equipment such as street lights are often used outdoors, and usually a single power supply supplies power to multiple identical loads, their operating voltages vary, some are extremely low, some are extremely high and can even reach hundreds of kilovolts. Therefore, the insulation quality of their connectors is a key factor in determining work safety and product life. Outdoors, it often rains, snows and other weather conditions, and the humidity is high. A damp connector not only has poor insulation performance and leakage, but also affects the performance of the product itself.

[0037] Therefore, the connector needs to be well protected from water, whether it is during normal operation or when the male and female plugs are not used together. Since the male and female plugs of the connector are generally integrated in two different modules or modules in advance, there are extra male plugs that are not used during transportation, maintenance, or outdoor wiring of these two different modules and modules. In order to prevent the intrusion of water or dust, it is often necessary to provide waterproof protection for the male and female plugs to prevent moisture from entering and causing damage to the modules or modules. However, in the current industrial waterproof connector, regarding the waterproof structure, only the waterproof cover can provide waterproof protection for the male or female plug separately, and the male and female plugs in paired use can be well protected from water. In addition, the existing male and female plugs have poor waterproof performance and cannot meet the use requirements under special conditions, which brings inconvenience to people's use.

[0038] Therefore, the present application provides a connector with a waterproof cover, which not only has good waterproof performance, but also includes a splitter, which can meet the application scenario requirements of a single power supply to multiple loads.
