[0022] Please see Figure 1-9 The present invention provides an embodiment of a foolproof connector, comprising a socket portion 1 and a plug portion 2 adapted to and connected to the socket portion 1; the socket portion 1 includes a housing 10, wherein a first power slot 15 and a second power slot 17 are provided in the housing 10, and a signal source slot 16 is provided between the first power slot 15 and the second power slot 17; wherein a first electrode 11 is installed in the first power slot 15, a second electrode 12 is provided in the second power slot 17, and a signal connector 13 is provided in the signal source slot 16;

[0023] In summary, when the first electrode 11 is inserted into the first power socket 15 and the second electrode 12 is inserted into the second power socket 17, the two power sockets can be used to protect the two electrodes. At the same time, the two power sockets are arranged vertically, with the signal source socket 16 in the center, to avoid the electrodes being exposed in the socket part 1. The power sockets and signal source socket 16 can also protect the electrodes and signal connector 13, effectively preventing dust or impurities from falling onto the electrodes or signal connector. In particular, each electrode and signal connector 13 is protected by its corresponding socket, which can effectively prevent rainwater from falling in and causing short circuits between the electrodes.

[0024] The plug portion 2 includes a housing 20, and a connector 23 is provided at one end of the housing 20 facing the socket portion 1. The connector 23 is provided with a first mounting area 215 and a second mounting area 219, and a third mounting area 217 is provided between the first mounting area 215 and the second mounting area 219. A first pin 210 is installed in the first mounting area 215 and is plugged into the first electrode 11. A second pin 211 is provided in the second mounting area 219 and is plugged into the second electrode 12. A signal source plug 212 is provided in the third mounting area 217 and is connected to a signal connector 13 in the signal source slot 16.

[0025] Based on this, while ensuring smooth circuit conduction, the plug part 2 is also provided with a first mounting area 215 corresponding to the first power slot 15, a second mounting area 219 corresponding to the second power slot 17, and a third mounting area 217 corresponding to the signal source slot 16. Therefore, the plug part 2 and the socket part 1 have reliable waterproof capability after connection. In particular, when the socket part 1 and the plug part 2 are plugged in, it not only facilitates the smooth connection of the electrodes and pins, but also avoids the problem of damage to the electrodes and pins during the plugging process due to mutual interference.

[0026] Furthermore, the connector 23 has a first contact portion 221 and a second contact portion 222 on the side facing the socket portion 1. The first contact portion 221 and the second contact portion 222 are used to offset the terminals of the first pin 210 and the second pin 211. Therefore, when the two pins abut against the corresponding contact portions, the terminals of the two pins can be offset, which not only separates the wires and reduces heat generation between them, but also makes full use of the internal space of the housing 20.

[0027] In order to facilitate the locking of the first electrode 11 and the second electrode 12 after assembly, the inner wall surfaces of the first power slot 15 and the second power slot 17 are provided with protrusions 18, and the outer wall surfaces of the first electrode 11 and the second electrode 12 are provided with buckles 110; the buckles 110 are fastened to the inner side of the protrusions 18 to fix the first electrode 11 in the first power slot 15.

[0028] In summary, due to the arrangement of the first power slot 15 and the second power slot 17, the two electrodes can be smoothly and quickly inserted into the corresponding slots. After insertion, the protrusion 18 and the buckle 110 cooperate to quickly lock the two electrodes, making the assembly of the electrodes simple and convenient, and ensuring that the position is stable and reliable after assembly.

[0029] In order for the first pin 210 and the second pin 211 to be locked in position after assembly, a buckle plate 216 is provided on the inner wall surface of the first mounting area 215 and the second mounting area 219; a buckle groove 213 adapted to and connected to the buckle plate 216 is provided on the first pin 210 and the second pin 211.

[0030] In summary, after the two pins are connected to their corresponding mounting areas, the cooperation between the snap plate 216 and the snap groove 213 ensures that the two pins can be reliably locked within their respective mounting areas. Based on this, the pins inside the plug part 2 are reliably fixed, and the electrodes inside the socket part 1 are reliably fixed, thus preventing the electrodes and pins from becoming loose during the insertion and removal process of the plug part 2.

[0031] Furthermore, since the first mounting area 215 and the second mounting area 219 are provided with grooves 218 on their sides, and the sides of the first pin 210 and the second pin 211 are located in the grooves 218, the grooves 218 can be used to guide the installation of the pins. At the same time, the grooves 218 can be used to further position the pins to ensure that the position of the pins is locked stably and reliably.

[0032] Furthermore, since the outer end faces of the first power slot 15 and the second power slot 17 are flush with each other, and the outer end face of the signal source slot 16 is offset from the outer end face of the first power slot 15, the plug portion 2 and the socket portion 1 can be easily and smoothly connected. After connection, the end faces of the first power slot 15 and the second power slot 17 enter the interior of the first mounting area 215 and the second mounting area 219, while the end face of the third mounting area 217 fits against the end face of the signal source slot 16. Therefore, after the plug portion 2 and the socket portion 1 are connected, the various mounting areas and slots inside are offset from each other, so as to ensure the stability of the plug connection.

[0033] Based on the above solution, in order to improve the waterproof and dustproof capabilities of the plug portion 2 and the socket portion 1, as well as the waterproof and dustproof capabilities after their connection, the outer wall surface of the connector 23 is provided with mounting grooves 214 for installing sealing rings, and the number of mounting grooves 214 is two. One mounting groove 214 contains a sealing ring for sealing between the outer shell 20 and the connector 23, and the other contains a sealing ring for sealing between the socket portion 1 and the connector 23. Therefore, the sealing rings in the two mounting grooves 214 can both seal the connector 23 and the outer shell 20 and ensure the sealing performance after the plug portion 2 and the socket portion 1 are connected.

[0034] Furthermore, the side of the socket portion 1 facing the plug portion 2 is also provided with a sealing gasket 19, and the sealing gasket 19 is used to seal the connection between the plug portion 2 and the socket portion 1. Therefore, when the plug portion 2 is connected to the socket portion 1, the end face of the plug portion 2 is pressed against the sealing gasket 19, which can further improve the sealing performance of the connection between the plug portion 2 and the socket portion 1.

[0035] Meanwhile, since the bottom of the outer casing 20 is also provided with a waterproof pad 25, and is connected to the outer casing 20 through a support plate 26 to fix the waterproof pad 25 inside the outer casing 20; wherein, the two sides of the support plate 26 are adapted to the lifting lugs 24 provided on the outer side of the outer casing 20 through lifting rings 27, thus improving the waterproof capability of the plug part 2 itself and effectively preventing moisture from entering the interior of the outer casing 20 through the wire.

[0036] In addition, since the outer shell 20 is also provided with a latch 21, the latch 21 is adapted to the locking pin 14 provided on the socket part 1 to lock the plug part 2 on the socket part 1. Therefore, the adaptation connection between the latch 21 and the locking pin 14 can be used to ensure the stability of the plug part 2 after it is connected to the socket part 1.

[0037] To facilitate the smooth assembly of connector 23 and housing 20, connector 23 is provided with a first connecting groove 22 on one side and a second connecting groove 28 on the other side. At the same time, housing 20 is provided with a first connecting pin 29 on one side and a second connecting pin 220 on the other side. The first connecting pin 29 is connected to the first connecting groove 22 to fix one side of connector 23, and the second connecting pin 220 is connected to the second connecting groove 28 to fix the other side of connector 23. Thus, connector 23 and housing 20 can be reliably fixed together.

[0038] To ensure directional correctness during assembly, the first connecting slot 22 is larger than the second connecting slot 28, further guaranteeing smooth assembly between the connector 23 and the housing 20. During assembly, the bottom of the connector 23 is placed against the bottom surface of the housing 20, and then pushed inwards. Simultaneously, the connector 23 is rotated upwards until the connecting pin engages with the corresponding connecting slot, achieving non-linear assembly of the connector 23. This non-linear assembly reduces the force required during assembly and prevents pulling or squeezing of the wires.

[0039] 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.
