Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figures 1-5 As shown, the outdoor waterproof power connector for LED displays of this utility model includes a plug and a socket. An elastic locking device is provided on the socket, which consists of a locking sleeve 2 and a spring 15. One end of the locking sleeve 2 is movably mounted on the socket and can rotate 360° on the socket. One or more claws 14 are provided on the inner wall of the locking sleeve 2. In this embodiment, two claws 14 are preferably provided, and the two claws 14 are symmetrically arranged on the inner wall of the locking sleeve 2. After the plug is inserted into the locking sleeve 2, it is plugged into and detached from the socket, and after the plug is inserted into the locking sleeve 2, it engages with the claws 14.

[0024] like Figure 5 As shown, the inner wall of the locking sleeve 2 is also provided with one or more spring top plates 13, which are located below the claw 14. The spring 15 is elastically connected to the spring top plate 13.

[0025] like Figure 2 and Figure 3 As shown, the connector includes a connector core 3, and a power receiving component and a signal transmission component embedded within the connector core 3. The core wall of the connector core 3 has a locking platform 5 that matches the locking claw 14, and the locking claw 14 engages with the locking platform 5. The power receiving component consists of a positive electrode conductive male pin 10 and a negative electrode conductive male pin 11.

[0026] The signal transmission component consists of several signal transmission male pins 4. These male pins 4 are evenly distributed on the connector core 3.

[0027] like Figure 2 As shown, the waterproof locking device includes a locking nut 16 and a waterproof sealing washer 17. The locking nut 16 is installed on the connector core 3 and is threadedly connected to the connector core 3. In use, after locking the locking nut 16, the waterproof sealing washer 17 is in close contact with the locking sleeve 2. This ensures better stability after the connector is inserted into the connector socket, while also achieving a waterproof effect.

[0028] like Figure 4 The connector comprises a base 1, a socket core 6, and conductive plug-in components and signal transmission plug-in components respectively disposed within the socket core 6. The socket core 6 is threadedly connected to the base 1. The conductive plug-in component includes a positive electrode male pin female connector 9 and a negative electrode male pin female connector 7. The positive electrode conductive male pin 10 is plugged into and out of the positive electrode male pin female connector 9, and the negative electrode conductive male pin 11 is plugged into and out of the negative electrode male pin female connector 7.

[0029] The socket core 6 has a mounting groove 12 for installing a spring 15 on its core wall. During installation, one end of the spring 15 is elastically connected to the spring top plate 13, and the other end is elastically connected to an inner groove wall of the mounting groove 12.

[0030] The signal transmission connector assembly consists of several male signal pins that plug into female connectors 8. The number of male signal pins that plug into female connectors 8 is the same as the number of male signal pins 4. The male signal pins 4 are plugged into and unplugged from the male signal pins that plug into female connectors 8.

[0031] In practical use, when it is necessary to align the connector with the socket, rotate the locking sleeve 2 clockwise and grip it firmly to prevent it from springing back under the action of the spring 15. Then, align the positive conductive male pin 10 on the connector core 3 with the positive conductive male pin female connector 9 on the socket core 6, the negative conductive male pin 11 on the connector core 3 with the negative conductive male pin female connector 7 on the socket core 6, and the signal transmission male pin 4 on the connector core 3 with the signal male pin female connector 8 on the socket core 6. Then, insert the connector core 3 into the socket core 6. At this time, release the locking sleeve 2, and it will automatically rotate counterclockwise under the action of the spring 15, causing the claw 14 on the locking sleeve 2 to engage with the locking platform 5, thus completing the alignment and locking of the connector with the socket. Finally, tighten the locking nut 16 on the connector core 3 to ensure that the waterproof sealing gasket 17 is in tight contact with the opening of the locking sleeve 2, preventing external rainwater from entering the socket.

[0032] This utility model has a simple structure and is easy to operate. By cooperating with the elastic locking device on the connector and the locking platform 5 on the connector, the connector and the connector can be quickly connected and fixed together. At the same time, the connector is also equipped with a waterproof locking device, which makes the connection between the connector and the connector more stable and waterproof. Thus, this utility model effectively solves the problem of the existing LED display power cable being not securely connected and easily falling off during use.

[0033] As described above, this utility model can be well realized.
