Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a T-type waterproof connector and power supply system, which is used in outdoor lighting systems. Background Technology

[0002] In traditional farm lighting systems, the lights are typically connected to a plugged cable at the driver end, with a length of about 1.5m. However, in large farms, the 1.5m cable length is still limited in practical use. This would require multiple power strips or electrical boxes to meet the power supply needs of a large environment, which is very inconvenient.

[0003] T-type waterproof connectors are highly safe when used under load limits, offering excellent waterproof protection. Their compact size compared to power strips and electrical boxes results in a neat and aesthetically pleasing appearance. Unlike power strips and electrical boxes, which often have numerous plugs crammed into one area, potentially causing a fire in one plug and affecting others in the same area, T-type waterproof connectors maintain sufficient distance between each connector, ensuring safety and reliability. Therefore, a power supply system using T-type waterproof connectors needs to be designed. Furthermore, existing T-type waterproof connectors have poor compatibility with lighting fixtures, necessitating the design of specialized connectors to ensure convenient and reliable connection. Summary of the Invention

[0004] One of the technical problems to be solved by this utility model is to provide a T-type waterproof connector to improve the convenience and reliability of connecting lamps with the T-type waterproof connector.

[0005] The second technical problem to be solved by this utility model is to provide a power supply system that is convenient to manage and safe and reliable.

[0006] To solve one of the above-mentioned technical problems, the technical solution of this utility model is: a T-type waterproof connector, including a connector body, first connecting components disposed at the left and right ends of the connector body, and a second connecting component disposed in the middle of the connector body. The left and right ends of the connector body are respectively provided with first connecting ports that cooperate with the first connecting components, and the middle of the connector body is provided with a second connecting port that cooperates with the second connecting component. The first connecting port includes a first connecting frame and a plurality of metal terminals, namely metal terminal L, metal terminal N, and metal terminal E. The metal terminals on the first connecting ports at the left and right ends correspond one-to-one and are electrically connected through conductors. The second connecting port includes a second connecting frame, from which a connecting body L connected to metal terminal L, a connecting body N connected to metal terminal N, and a connecting body E connected to metal terminal E are led out. The second connecting component includes a quick-locking self-locking nut fitted on the second connecting frame. The principle of this invention is as follows: Several T-type waterproof connectors are connected in series to quickly form a complete power supply system, converting three-phase to single-phase, which can form a long power supply system, facilitating the distribution of lights in large farms. Connections can be added or removed according to the actual load, making it convenient and quick, requiring only a power source at the origin. The T-type waterproof connector uses an M19 female connector with a quick-locking nut, and an M19 male connector is used simultaneously in the light fixture driver for quick matching and connection. The connection is convenient, quick, and saves time and effort. After connection, the quick-locking female and male connectors form a tight and secure connection that cannot be easily pulled off.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figures 1 to 3As shown, a power supply system includes several T-type waterproof connectors arranged in series. Each T-type waterproof connector includes a connector body 1, first connecting components 2 located at the left and right ends of the connector body 1, and a second connecting component 3 located in the middle of the connector body 1. The left and right ends of the connector body 1 are respectively provided with first connecting ports 12 that mate with the first connecting components 2, and the middle of the connector body 1 is provided with a second connecting port 12 that mates with the second connecting components 3. Each first connecting port 12 includes a first connecting frame and several metal terminals, namely metal terminal L, metal terminal N, and metal terminal E. The metal terminals on the first connecting ports 12 at the left and right ends correspond one-to-one and are electrically connected through conductors. If the T-type waterproof connector is a single-phase input, there is only one metal terminal L; if the T-type waterproof connector is a three-phase input, there are three metal terminals L, namely metal terminal L1, metal terminal L2, and metal terminal L3. The second connecting port 12 includes a second connecting frame, from which a connecting body L connected to metal terminal L, a connecting body N connected to metal terminal N, and a connecting body E connected to metal terminal E are led out. If it is a single-phase input, such as... Figure 7 As shown, the connector L is connected to the metal terminal L; if it is a three-phase input, as... Figure 4-6 As shown, if connector L is connected to metal terminal L1, it is an L1 T-type waterproof connector; if connector L is connected to metal terminal L2, it is an L2 T-type waterproof connector; and if connector L is connected to metal terminal L3, it is an L3 T-type waterproof connector. These three types of T-type waterproof connectors with different circuits can be arbitrarily matched and connected in series. In this embodiment, five L1 T-type waterproof connectors are initially connected, followed by five L2 T-type waterproof connectors, and finally five L3 T-type waterproof connectors. The first connection ports 12 of adjacent T-type waterproof connectors are connected in series via cables. The cables use 5×2.5mm² copper wire, and the cable length can be customized according to the actual application. The first connecting assembly 2 includes a connecting sleeve 21, a threaded sleeve 24, a clamp 23, and a silicone pad 22. One end of the connecting sleeve 21 is threaded to the first connecting frame, and the other end of the connecting sleeve 21 is threaded to the threaded sleeve 24. The silicone pad 22 is located inside the threaded sleeve 24, and the clamp 23 is located between the threaded sleeve 24 and the silicone pad 22. Tightening the threaded sleeve 24 forces the clamp 23 to press the silicone pad 22 tightly, thus providing good waterproof performance for the connected cable. The connector body 1 is provided with a lifting lug 11 for hanging and installing the T-type waterproof connector. The second connecting assembly 3 includes a quick-lock self-locking nut 32 fitted onto the second connecting frame. The surface of the second connecting frame is provided with an annular protrusion 13. The quick-lock self-locking nut 32 includes a connecting cylinder, a flange located at the rear end of the connecting cylinder, and several locking points located on the inner wall of the connecting cylinder. The flange abuts against the rear end of the annular protrusion, and a sealing ring 31 is provided inside the quick-lock self-locking nut 32 at the front end of the annular protrusion 13.

[0029] The principle of this invention is as follows: Several T-type waterproof connectors are connected in series to quickly form a complete power supply system, converting three-phase to single-phase, which can form a long power supply system, facilitating the distribution of lights in large farms. Connections can be added or removed according to the actual load, making it convenient and quick, requiring only a power source at the origin. The T-type waterproof connector uses an M19 female connector with a quick-locking nut, and an M19 male connector is used simultaneously in the light fixture driver for quick matching and connection. The connection is convenient, quick, and saves time and effort. After connection, the quick-locking female and male connectors form a tight and secure connection that cannot be easily pulled off.
