[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0018] Please see Figure 1-4This utility model provides an embodiment of a junction box connector, comprising a terminal block 1 and a three-way junction box 2 movably connected to the terminal block 1; the three-way junction box 2 has a slot 20 at one end facing the terminal block 1, and a first connecting groove 21 is also provided on the inner wall of the slot 20; the terminal block 1 includes a plug 10, and a first connecting pin 11 is also provided on the outer wall of the plug 10; after the plug 10 is inserted into the slot 20, the first connecting pin 11 is adapted to the first connecting groove 21 to fix the three-way junction box 2 on the plug 10.

[0019] In summary, after one end of the power cord is connected to the plug 10, the other end of the power cord is branched off through the three-way junction box 2. Finally, the three-way junction box 2 is connected to the plug 10. After the two are connected, the first connecting pin 11 is connected to the first connecting slot 21 to improve the stability of the connection. Based on this, since the terminal block 1 and the three-way junction box 2 are separate structures, the device is convenient for power connection and assembly of the three-way junction box 2 and the terminal block 1. In particular, the three-way junction box 2 and the terminal block 1 can be disassembled to facilitate the installation and replacement of the power supply.

[0020] Furthermore, since the slot 20 is also provided with a second connecting slot 22, and the outer wall of the plug 10 is also provided with a second connecting pin 12 that is adapted to and connected to the second connecting slot 22, the connection of the two connecting slots and the two connecting pins can be used to further enhance the stability of the connection between the terminal block 1 and the three-way junction box 2.

[0021] Furthermore, since the length of the first connecting groove 21 is less than the length of the second connecting groove 22, the contact area between the connecting pin and the connecting groove can be increased to improve the stability of the connection between the three-way junction box 2 and the terminal block 1.

[0022] Based on the above solution, since the outer wall of the plug 10 is also provided with a shaft pin seat 17, and the three-way junction box 2 is also provided with a slot 23, after the three-way junction box 2 is connected to the terminal block 1, one end of the shaft pin seat 17 is inserted into the slot 23. Therefore, when the shaft pin seat 17 enters the slot 23, the slot 23 can be used to prevent the plug 10 from rotating in the slot 20, thus playing a limiting role.

[0023] When the splitter connector is connected to the socket, the middle part of the latch 14 is connected to the pivot pin seat 17, and the end of the latch 14 away from the three-way junction box 2 is also provided with a locking hole 18, which is pressed onto the locking pin by a spring 13. Therefore, the locking hole 18 can be used to fasten onto the locking pin on the socket, and the spring 13 can also be used to ensure that the locking hole 18 can be reliably fitted onto the locking pin, thereby improving the stability of the device when connected to the socket.

[0024] Furthermore, since the plug 10 is also provided with a support platform 15, and the spring 13 causes the latch 14 to abut against the support platform 15, the entire latch 14 can be parallel to the upper surface of the pin seat 17, thus avoiding the problem that one end of the latch 14 may easily snag an object due to being raised.

[0025] In addition, since the pin seat 17 is also provided with a fixing groove 16 for fixing the spring 13, one end of the spring 13 is fixed, thus preventing the spring 13 from sliding in the pin seat 17 when compressed.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
