[0035] Please refer to Figures 1 to 14, a waterproof connector 20 provided by an embodiment of the present utility model for a low-voltage metering and monitoring device 10. The waterproof connector 20 includes a socket 21 embedded in the low-voltage metering and monitoring device 10 and a plug 22 plugged into the socket 21. Here, one end of the socket 21 away from the plug 22 adopts a pin method and is directly welded to the circuit board located inside the low-voltage metering and monitoring device 10, thus saving the trouble of wiring. A fixing plate 23 extends around the edge of the socket of the socket 22. On one side of the low-voltage metering and monitoring device 10 where the socket 21 is located, there is a fixing box 11 for fixing the socket 21. The fixing box 11 plays a role in fixing the socket 21, and thus plays a role in fixing the waterproof connector 20. On one side of the fixing box 11 away from the low-voltage metering and monitoring device 10, an installation hole 111 adapted to the socket 21 is opened. Through the setting of the fixing box 11, the waterproof connector 20 is perfectly assembled with the low-voltage metering and monitoring device 10, meeting the wiring layout requirements of the low-voltage metering device 10. A first groove (not marked in the figure) for accommodating the fixing plate 23 is recessed around the edge of the installation hole 111. The socket 21 is sleeved with a first silicone pad 24 adapted to the fixing plate 23 and attached to the fixing plate 23. The first silicone pad 24 plays a waterproof role to prevent rainwater from entering the socket 21 to meet the outdoor IP67 waterproof requirement. On both side walls at the top end of the plug 22, there are respectively provided buckle members 221 extending towards the tail end of the plug 22 and in a V shape with the plug 22. The buckle members 221, like the plug 22, are plastic parts and have pressing elasticity. On both side walls at the tail end of the plug 22, there are respectively provided pressing members 222 extending towards the top end of the plug 22 and in a V shape with the plug 22. The pressing members 222 are plastic parts and have pressing elasticity. The buckle members 221 are respectively arranged inside the pressing members 222. When the pressing members 222 are pressed, the buckle members 221 can be compressed so as to plug the plug 22 into the socket 21 interface. Through the cooperation of the pressing members 222 and the buckle members 221, the plug 22 can be clamped in the socket 21, and it is also convenient to pull out the plug 22 from the socket 21.

[0036] Such as Figure 3 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 And Figure 12As shown, in this embodiment, when the plug 22 needs to be inserted into the socket 21, press the pressing member 222. The pressing member 222 is pressed and compressed in the direction of the buckle member 221, thereby compressing the buckle member 221 so that the buckle member 221 is pressed, enabling the plug 22 to be inserted into the socket 21. After the plug 22 is inserted into the socket 21, stop pressing the pressing member 222. The pressing member 222 returns to its initial state and no longer compresses the buckle member 221. The buckle member 221 presses the socket 21 under the action of the elastic restoring force, playing a role in locking and fixing the plug 21 and preventing the plug 22 from falling out of the socket 21. Conversely, when it is necessary to pull out the plug 22 from the socket 21, press the pressing member 222 again. The pressing member 222 is pressed and compressed in the direction of the buckle member 221, thereby compressing the buckle member 221 so that the buckle member 221 is pressed, enabling the buckle member 221 to stop pressing the socket 21 and facilitating the plug 22 to be pulled out of the socket 21.

[0037] It should be noted that in this embodiment, the plug 22 realizes integrated wiring. All the sensors are already wired to the plug 22 when they are produced and shipped. During on-site construction, only the plug 22 needs to be inserted into the socket 21, reducing the difficulty of on-site construction.

[0038] In this embodiment, as Figure 1 and Figure 4 shown, at the four corners on one side of the socket, the low-voltage metering and monitoring device 10 is respectively provided with a first screw hole 12. At the four corners of the fixing box 11, there is respectively provided a second screw hole 13 corresponding to the first screw hole 12. The fixing box 11 and the low-voltage metering and monitoring device 10 are detachably fixed together through the cooperation of screws, the first screw hole 12 and the second screw hole 13. In this way, it not only plays a waterproof role but also plays a role in fixing the socket 21.

[0039] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a fixing wall 14 is provided in a circular shape around the four peripheral edges on one side of the socket 21 of the low-voltage metering and monitoring device 10. The inner side wall of the fixing box 11 is in contact with the outer side wall of the fixing wall 14. In this way, it not only plays a waterproof role but also plays a role in fixing the fixing box 11.

[0040] In this embodiment, as Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 、Figure 10 , Figure 11 and Figure 12 As shown, the latch 221 gradually descends from the bottom end of the latch 221 to the top end of the latch 221 along the direction from the socket 21 to the plug 22, so that a V-shape is formed between the latch 221 and the plug 22, and the pressing piece 222 gradually rises from the bottom end of the pressing piece 222 to the top end of the pressing piece 222 along the direction from the plug 22 to the socket 21, so that a V-shape is formed between the pressing piece 222 and the plug 22, so that when the pressing piece 222 is pressurized, the latch 221 can be compressed so that the plug 22 can be plugged into the interface of the socket 21 or the socket 22 can be pulled out from the socket 21.

[0041] In this embodiment, Figure 8 and Figure 9 As shown, the side of the latch 221 away from the plug 22 is provided with a second groove 2211 matching the interface of the socket 21 and an anti-slip groove 2212 corresponding to the pressing piece 222 in sequence along the direction from the socket 21 to the plug 21. In this way, through the setting of the second groove 2211, when the plug 22 is inserted into the interface of the socket 21, the plug 21 can be better locked and fixed in the socket 21. Through the setting of the anti-slip groove 2212, it is convenient for the pressing piece 222 to squeeze the latch 221 so as to insert the plug 22 into the socket 21 or pull the plug 22 out of the socket 21.

[0042] In this embodiment, a second silicone pad (not shown in the figure) is provided in the interface of the socket 21, so that when the plug 22 is plugged into the socket 21, the second silicone pad plays a waterproof role to meet the outdoor IP67 waterproof requirements.

[0043] In this embodiment, a third screw hole 231 is respectively provided at the four corners of the fixing plate 23, and a fourth screw hole and a fifth screw hole 241 corresponding to the third screw hole 231 are respectively provided at the four corners of the first groove and the four corners of the first silicone pad 24. The socket 21 and the first silicone pad 24 are detachably fixed to the fixing box 11 by the cooperation of screws, the third screw hole 231, the fourth screw hole and the fifth screw hole 241. The first silicone pad 24 plays a waterproof role to prevent rainwater from entering the socket 21.

[0044] It should be noted that in this embodiment, the jacks in the socket 22 interface are divided into a high-voltage area and a low-voltage area. Correspondingly, the pins of the plug 21 are divided into a high-voltage pin area corresponding to the high-voltage area and a low-voltage pin area corresponding to the low-voltage area. This independent separation of high and low voltages ensures electrical safety.

[0045] The waterproof joint for the low-voltage metering and monitoring device provided in the above embodiment of the present utility model includes a socket embedded in the low-voltage metering and monitoring device and a plug inserted into the socket. A fixing plate is provided around the edge of the socket opening. A fixing box for fixing the socket is provided on one side of the low-voltage metering and monitoring device. Through the setting of the fixing box, the waterproof joint is perfectly assembled with the low-voltage metering and monitoring device, meeting the wiring layout requirements of the low-voltage metering device. The fixing box is provided with an installation hole adapted to the socket, and a first groove for accommodating the fixing plate is formed by concave inward around the edge of the installation hole. The socket is sleeved with a first silicone pad adapted to the fixing plate and attached to the fixing plate. The first silicone pad plays a waterproof role to meet the outdoor IP67 waterproof requirement. On both side walls at the top of the plug, there are respectively provided buckle members extending towards the tail end of the plug and in a V shape with the plug. On both side walls at the tail end of the plug, there are respectively provided pressing members extending towards the top end of the plug and in a V shape with the plug. When the pressing member is pressed, the buckle member can be compressed to facilitate inserting the plug into the socket interface or pulling out the plug from the socket, effectively solving the problems that the existing joints do not meet the wiring layout requirements of the low-voltage metering device or do not meet the waterproof requirements.

[0046] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly.
