Description

Technical Field

[0001] This utility model relates to a wiring structure for an electric vehicle charging base. Background Technology

[0002] With rising global environmental awareness and the rapid growth of the electric vehicle market, competition within the electric vehicle market is also gradually intensifying. To enhance competitiveness, adding more structures and functions within a limited space can improve the efficiency of electric vehicles, thus becoming a key factor in attracting consumers. The component layout in the charging system is one of the key factors affecting the internal space of an electric vehicle. Therefore, existing electric vehicle charging sockets use a 90-degree cable exit design to reduce the volume occupied by the charging socket.

[0003] However, existing charging docks with cables extending at a 90-degree angle have cables that first protrude downwards from the charging dock flange before turning 90 degrees. If there are other structures below the flange, interference can occur between the cables and these structures. This necessitates a complete redesign of the overall structural layout, resulting in additional work time and consequently delaying the sale of electric vehicles, thus reducing their competitiveness in the market. Utility Model Content

[0004] This utility model proposes a wiring structure for an electric vehicle charging base that can effectively prevent pins from extending out of a specific direction from the charging base, thus preventing interference with other components that are expected to be installed in the vicinity.

[0005] The electric vehicle charging dock wiring structure proposed in this utility model has the following features: A main body having at least one cavity; the cavity being formed through the interior of the main body; the cavity being L-shaped, with one segment extending along a first connecting direction and the other segment extending along a second connecting direction perpendicular to the first connecting direction; the cavity having a first opening and a second opening; the first opening being formed at one end of the cavity and facing the first connecting direction; the second opening being formed at the other end of the cavity and facing the second connecting direction; A socket body having at least one pin; the pin passes through a portion of the cavity from the first opening and extends along the first connection direction; At least one terminal is disposed in the cavity and connected to the pin.

[0006] The advantage of this invention is that the extension direction of the pins is the same as the extension direction of one segment of the cavity, while the extension direction of the other segment of the cavity does not face downwards. In other words, the main body of this invention first protrudes rearwards from the socket body and then extends in a turning direction. That is, viewed from the front of the socket body, the main body of this invention does not protrude from below the socket body. Therefore, when other component structures are arranged below the socket body, there will be no interference between these other component structures and this invention. Attached Figure Description

[0020] Therefore, in this embodiment, at least one pin 21 includes two pins, namely a DC pin 21A and an AC pin 21B.

An AC terminal 40B is disposed in an AC cavity 11B, located between one segment and the other segment of the AC cavity 11B, and connected to an AC pin 21B and an AC cable 30B. At least one temperature sensor 50 includes two temperature sensors 50. One temperature sensor 50 contacts the DC terminal 40A and is capable of sensing the temperature of the DC terminal 40A. The other temperature sensor 50 contacts the AC terminal 40B and is capable of sensing the temperature of the AC terminal 40B.

[0021] At least one terminal fixing member 12 includes two terminal fixing members 12, which are respectively disposed in a DC cavity 11A and an AC cavity 11B. One terminal fixing member 12 fixes a DC terminal 40A in the DC cavity 11A, and its outer wall surface is in contact with the inner wall surface of the DC cavity 11A. The DC terminal 40A is disposed in one of the terminal fixing members 12, and the snap-fit ​​groove 41 of the DC terminal 40A is engaged with the snap-fit ​​portion 121 of one of the terminal fixing members 12.

[0023] In this embodiment, at least one disassembly opening 16 has a normal direction parallel to the first connection direction D1 and includes two disassembly openings 16. One disassembly opening 16 connects the DC cavity 11A to the outside and is positioned corresponding to the DC terminal 40A. The other disassembly opening 16 connects the AC cavity 11B to the outside and is positioned corresponding to the AC terminal 40B. At least one sealing cover 17 includes two sealing covers 17, and the sealing covers 17 are respectively disposed in the two disassembly openings 16. In addition, because one section of the DC cavity 11A and one section of the AC cavity 11B are arranged side by side along the second connection direction D2, and the other section of the DC cavity 11A and the other section of the AC cavity 11B are arranged side by side along the first connection direction D1, the other disassembly opening 16 cannot directly connect the AC cavity 11B to the outside. Therefore, in this embodiment, the main body 10 further has a through hole 18, which penetrates the wall between the DC cavity 11A and the AC cavity 11B and connects the DC cavity 11A and the AC cavity 11B. The position of the through hole 18 corresponds to another disassembly opening 16. In other words, the other disassembly opening 16 is sequentially connected to the DC cavity 11A, the through hole 18, and the AC cavity 11B.

[0024] In the process of manufacturing the wiring structure of the electric vehicle charging dock, the cable 30 is first passed through the wire harness cover 15 and the cable sealing ring 14. Then, the cable 30 and the terminal 40 are soldered together, and the terminal 40 and the temperature sensor 50 are installed in the terminal fixing member 12. Subsequently, the terminal fixing member 12 is inserted into the cavity 11 through the second opening 112, and the pin 21 of the socket body 20 is inserted into the cavity 11 through the first opening 111. The terminal 40 and the pin 21 are then locked in place by the locking fastener 13 through the self-removal opening 16 to complete the manufacturing of the electric vehicle charging dock wiring structure.

[0025] The advantages of this invention are that the extension direction of the DC pin 21A is the same as the extension direction of one segment of the DC cavity 11A, and the extension direction of the AC pin 21B is the same as the extension direction of one segment of the AC cavity 11B. Furthermore, the extension direction of the other segment of the DC cavity 11A and the other segment of the AC cavity 11B does not face downwards. In other words, the main body 10 of this invention first protrudes backwards from the socket body 20, and then extends in a turning direction. That is, viewed from the front of the socket body 20, the main body 10 of this invention does not protrude from below the socket body 20. Therefore, when other component structures are arranged below the socket body 20, there will be no interference between these other component structures and this invention. In addition, the cable sealing ring 14 gives this invention waterproof and dustproof functions, thereby ensuring the reliability and safety of the charging process.
