The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

The internal circuit plug connector for an electrical box in this embodiment includes a connector assembly 100 and a plug connector 300. Plug slots 103 are provided on both sides of one end of the connector assembly 100, and conductive terminals 301 inserted into the plug slots 103 are provided on both sides of the outer wall of one side of the plug connector 300. In this embodiment, the conductive terminal 301 can be inserted into the plug slot 103 to complete the connection of the circuit.

[0031] like Figure 2 as well as Figure 3As shown, it is a schematic diagram of the structure of the connector assembly and a schematic diagram of the bonding structure of the first conductive sheet and the second conductive sheet in this embodiment. The connector assembly 100 includes a first shell 101 and a second shell 102. Two insertion grooves 107 are arranged on the side of the first shell 101 and the second shell 102 away from the plug-in slot 103. The insertion grooves 107 on both sides are arranged on the side close to the plug-in slot 103. A mounting groove 106 is arranged. A connecting groove 105 is arranged between the plug-in slot 103 and the mounting groove 106. The interior of the insertion groove 107 is detachably connected with a connecting terminal 201. The outer wall of the connecting terminal 201 close to the plug-in slot 103 is fixedly connected with the first conductive sheet 200 inserted into the mounting groove 106. The interior of the plug-in slot 103 is slidably connected with a third conductive sheet 206. The outer wall of the third conductive sheet 206 close to the inner wall of the plug-in slot 103 is fixedly connected with The conductive column 203 passes through the connecting groove 105, and the end of the conductive column 203 is fixedly connected with the second conductive sheet 202. The conductive column 203 is located on the outer wall of the plug-in slot 103 and is provided with a second spring 204. An insulating sheet 205 is provided between the second spring 204 and the third conductive sheet 206. In this embodiment, when the conductive terminal 301 is inserted into the plug-in slot 103, the third conductive sheets 206 on both sides move inward and the second conductive sheet 202 fits with the first conductive sheet 200 to complete the circuit conduction, and the second spring 204 is compressed during the movement. When the plug connector 300 is unplugged, the second spring 204 rebounds to move the third conductive sheet 206 outward, thereby pushing out impurities inside the plug-in slot 103 and preventing external impurities from entering the plug-in slot 103 when not in use.

[0032] It is worth noting that the third conductive sheet 206, the second spring 204, the conductive column 203 and the second conductive sheet 202 are conductive components in this embodiment, and the conductive components include but are not limited to the third conductive sheet 206, the second spring 204, the conductive column 203 and the second conductive sheet 202. As long as the components can make the circuit connected when the conductive terminal 301 is inserted and seal the inside of the plug-in slots 103 on both sides when the conductive terminal 301 is pulled out, they can be applied to this embodiment.

In this embodiment, the plug connector 300 can be limited by the limiting columns 209 so that it will not fall off after connection, and the components connected to the connecting terminal 201 can also be limited.

[0034] It is worth noting that the above-mentioned mounting plate 208 and limiting column 209 are limiting components in this embodiment, and the limiting components include but are not limited to the mounting plate 208 and limiting column 209. As long as it is a component that can limit the plug connector 300 after connection, it can be applied to this embodiment.

In this embodiment, under normal conditions, the elastic force of the first spring 110 causes the limiting cover plates 210 on both sides to move to the top of the mounting plate 208, thereby preventing the limiting column 209 from falling off.

[0036] like Figure 4 As shown, a rubber pad 211 is provided at the bottom concave portion of the limiting cover plate 210 , and the rubber pad 211 can be slightly deformed, thereby increasing the fault tolerance of the bottom concave portion of the limiting cover plate 210 being stuck at the mounting plate 208 .
