Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a plug and charging device. Background Technology

[0002] Electric vehicle power cord plugs typically come in only one type, meaning they have only one type of pin unit, with each pin unit containing multiple prongs. To accommodate different socket sizes, adapters are usually included. For example, the plug that comes with the charging cable typically has a 10A pin unit, which is compatible with a standard 10A household socket. However, if it needs to be used with a 16A socket, a 10A to 16A adapter is required to accommodate the pin spacing of the 16A socket.

[0003] This method of setting up the plug to adapt to different socket sizes is rather cumbersome, and the adapter and charging cable are usually stored separately, making them prone to being lost. Utility Model Content

[0036] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0037] In the description of this utility model, it should be understood that the terms "longitudinal", "radial", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figure 1 and Figure 2As shown, in one embodiment, the plug 10 includes a base 1, a first-specification pin unit 2, and a second-specification pin unit 3; the outer surface of the base 1 is provided with a first through hole 11 and a second through hole 12; one end of the first-specification pin unit 2 is located inside the base 1, and the other end of the first-specification pin unit 2 extends out of the base 1 from the first through hole 11 to mate with a first pair of components; the second-specification pin unit 3 is located inside the base 1 and is connected to the inner side of the second through hole 12 so as to electrically connect to a second pair of components through the second through hole 12. The second-specification pin unit 3 being located inside the second through hole 12 means that the second-specification pin unit 3 does not extend out of the base 1 from the second through hole 12.

[0040] In this embodiment, the plug 10 includes two types of pin units, allowing it to be used with sockets of different sizes, thereby improving the plug 10's adaptability to different socket sizes. Furthermore, the plug 10 provided in this embodiment can be used with sockets of different sizes without the need for an adapter, thus avoiding the problems of cumbersome use and easy loss of adapters found in existing technologies.

[0041] In addition, the first-specification pin unit 2 extends out of the base 1, while the second-specification pin unit 3 does not extend out of the base 1. In this way, when the first-specification pin unit 2 is engaged with the first pair of parts, the second-specification pin unit 3 can avoid interfering with the engagement. Similarly, when the second-specification pin unit 3 is engaged with the second pair of parts, the first-specification pin unit 2 can avoid interfering with the engagement.

[0042] It should be noted that both the first-specification pin unit 2 and the second-specification pin unit 3 can be existing designs. Both the first and second pairs of connectors can be corresponding sockets.

[0043] In one embodiment, the first pin unit 2 can be a 10A pin unit, and the second pin unit 3 can be a 32A pin unit. Of course, in other embodiments, the first pin unit 2 and the second pin unit 3 can be pin units with different specifications.

[0044] like Figure 2 As shown, in one embodiment, the first specification pin unit 2 includes a plurality of first sub-pins 21 spaced apart; each first sub-pin 21 has a portion located inside the base 1 and extends out of the base 1 from the first through hole 11; the second specification pin unit 3 includes a plurality of second sub-pins 31 spaced apart; each second sub-pin 31 is located inside the base 1 and can be electrically connected to a counterpart through the second through hole 12; the first sub-pin 21 and the second sub-pin 31 correspond one-to-one, and the end of the first sub-pin 21 located inside the base 1 is electrically connected to its corresponding second sub-pin 31.

[0045] This way, only one conductive wire is needed to simultaneously power the corresponding first sub-pin 21 and second sub-pin 31, which can reduce costs.

[0046] In addition, "multiple" means two or more. The meaning of the word "multiple" is the same in all embodiments and will not be repeated hereafter.

[0047] like Figure 2 As shown, in one embodiment, the first specification pin unit 2 has two first sub-pins 21, and the second specification pin unit 3 has two second sub-pins 31. The two first sub-pins 21 are used to electrically connect the neutral wire and the live wire of the mains power supply, respectively, and the two second sub-pins 31 are used to electrically connect the neutral wire and the live wire of the mains power supply, respectively.

[0048] like Figure 1 As shown, in one embodiment, the first via 11 includes a plurality of first sub-holes 111 spaced apart, with each first sub-pin 21 corresponding to a first sub-hole 111, and the first sub-pin 21 extending out of its corresponding first sub-hole 111 from the base 1; the second via 12 includes a plurality of second sub-holes 121 spaced apart, with each second sub-pin 31 corresponding to a second sub-hole 121, and the second sub-pin 31 electrically connecting to a second pair of components from its corresponding second sub-hole 121. This arrangement can improve the safety of using the first-specification pin unit 2 and the second-specification pin unit 3.

[0049] like Figure 2 As shown, in one embodiment, the first-specification pin unit 2 further includes a grounding pin 22, and the first via 11 further includes a grounding sub-hole 112 spaced between the first sub-hole 111 and the second sub-hole 121; a portion of the grounding pin 22 is located inside the base 1 and extends out of the base 1 from the grounding sub-hole 112. The grounding pin 22 is used for electrical connection to the ground wire to improve the safety of the first-specification pin unit 2.

[0050] In addition, the grounding pin 22 can also be used as the grounding terminal of the second specification pin unit 3 to simplify the structure of the plug 10 and reduce the cost of the plug 10.

[0051] like Figure 2 and Figure 5 As shown, in one embodiment, the plug 10 further includes a connector 4, which is located inside the base 1 and electrically connected to the corresponding first sub-pin 21 and second sub-pin 31. Electrically connecting the first sub-pin 21 and second sub-pin 31 via the intermediate element (i.e., connector 4) facilitates the arrangement and structural configuration of the first sub-pin 21 and second sub-pin 31.

[0052] like Figure 2 and Figure 5As shown, in one embodiment, the connector 4 includes a first connecting portion 41, a second connecting portion 42, and a third connecting portion 43 connected in sequence. The first connecting portion 41 is connected to the first sub-pin 21, and the third connecting portion 43 is connected to the second sub-pin 31. The first connecting portion 41 and the second connecting portion 42 are connected to form a first bending structure, and the second connecting portion 42 and the third connecting portion 43 are connected to form a second bending structure. The bending direction of the first connecting portion 41 is opposite to the bending direction of the third connecting portion 43, so that the connector 4 has a Z-shaped structure as a whole. This arrangement is beneficial to make the corresponding first sub-pin 21 and second sub-pin 31 have a larger distance between them. At the same time, it can achieve electrical connection between the first sub-pin 21 and the second sub-pin 31 without the first sub-pin 21 needing to be too long, and make it extend out of the base 1 by a sufficient length.

[0053] The fact that the bending direction of the first connecting part 41 is opposite to that of the bending direction of the third connecting part 43 means that the included angle between the first connecting part 41 and the second connecting part 42, and the included angle between the second connecting part 42 and the third connecting part 43, are located on opposite sides of the second connecting part 42.

[0054] In one embodiment, the first connecting portion 41, the second connecting portion 42, and the third connecting portion 43 can all be metal plates, and all three can be flat plate structures. Furthermore, the included angle between the first connecting portion 41 and the second connecting portion 42 can be a right angle, an obtuse angle, or an acute angle. The included angle between the second connecting portion 42 and the third connecting portion 43 can be a right angle, an obtuse angle, or an acute angle. The included angle between the first connecting portion 41 and the third connecting portion 43 can be zero degrees, or it can be a right angle, an obtuse angle, or an acute angle.

[0055] like Figure 2 As shown, in one embodiment, the first sub-pin 21 is provided with a first protrusion structure 211, and the second sub-pin 31 is provided with a second protrusion structure 311; the first connecting portion 41 is provided with a first socket 411, and the third connecting portion 43 is provided with a second socket 431; the first sub-pin 21 passes through the first socket 411, and the first protrusion structure 211 abuts against the surface of the first connecting portion 41 away from the surface of the second connecting portion 42; the second sub-pin 31 passes through the second socket 431, and the second protrusion structure 311 abuts against the surface of the third connecting portion 43 away from the surface of the second connecting portion 42. During assembly, the first sub-pin 21 can be inserted into the first socket 411, the second sub-pin 31 can be inserted into the second socket 431 and abut against the first connecting part 41, and the first protruding structure 211 can abut against the first connecting part 41, and the second protruding structure 311 can abut against the third connecting part 43. In this way, the relative position between the first sub-pin 21 and the second sub-pin 31 can be limited by the connector 4, which facilitates the subsequent assembly of the plug 10.

[0056] like Figure 1 , Figure 3 as well as Figure 4 As shown, in one embodiment, the base 1 includes a bottom shell 13 and a cover 14. The bottom shell 13 has a first surface 131 and a second surface 132 disposed opposite to each other. A receiving hole 133 is provided on the first surface 131, and the cover 14 closes the opening formed on the first surface 131 by the receiving hole 133. The first through hole 11 and the second through hole 12 are both connected to the receiving hole 133. One end of the first-specification plug unit 2 is located inside the receiving hole 133. The second-specification plug unit 3 is located inside the receiving hole 133. This facilitates the assembly of the plug 10.

[0057] Wherein, one end of the first specification pin unit 2 is located in the receiving hole 133, which means that the end of the first specification pin unit 2 is located in the base 1, and the second specification pin unit 3 is located in the receiving hole 133, which means that the second specification pin unit 3 is located in the base 1.

[0058] like Figure 4 As shown, in one embodiment, both the first through hole 11 and the second through hole 12 are located on the second surface 132. This facilitates the manufacturing and processing of the base 1, thereby facilitating the production of the plug 10.

[0059] In one embodiment, both the first-specification pin unit 2 and the second-specification pin unit 3 abut against the bottom surface of the receiving hole 133. This allows for a certain degree of limitation on the installation position of the first-specification pin unit 2 and the second-specification pin unit 3 within the bottom housing 13 during the assembly of the plug 10.

[0060] In addition, the first specification pin unit 2 contacting the bottom surface of the receiving hole 133 can mean that each first sub-pin 21 and grounding pin 22 contact the bottom surface of the receiving hole 133.

[0061] The second specification pin unit 3 abutting the bottom surface of the receiving hole 133 can mean that each second sub-pin 31 abuts the bottom surface of the receiving hole 133.

[0062] like Figure 3 As shown, in one embodiment, the base 1 further includes a first limiting structure 15 and a second limiting structure 16; the first limiting structure 15 is used to limit the position of the first specification pin unit 2 in the radial direction of the receiving hole 133 relative to the bottom shell 13; the second limiting structure 16 is used to limit the position of the second specification pin unit 3 in the radial direction of the receiving hole 133 relative to the bottom shell 13; the first limiting structure 15 and the second limiting structure 16 are both provided on the bottom surface of the receiving hole 133.

[0063] This allows for better positioning of the first-specification pin unit 2 and the second-specification pin unit 3 within the bottom shell 13, thus facilitating the assembly of the plug 10.

[0064] In addition, the first limiting structure 15 is used to limit the position of the first specification pin unit 2 in the radial direction of the receiving hole 133 relative to the bottom shell 13. This can mean that the first limiting structure 15 is used to limit each first sub-pin 21 and the grounding pin 22 to limit the position of each first sub-pin 21 and the grounding pin 22 in the radial direction of the receiving hole 133 relative to the bottom shell 13.

[0065] The second limiting structure 16 is used to limit the position of the second specification pin unit 3 in the radial direction of the receiving hole 133 relative to the bottom shell 13. This can mean that the second limiting structure 16 is used to limit each second sub-pin 31 to limit the position of each second sub-pin 31 in the radial direction of the receiving hole 133 relative to the bottom shell 13.

[0066] like Figure 3 As shown, in one embodiment, the first limiting structure 15 includes a plurality of first sub-limiting units 151. Each first sub-pin 21 is limited by a first sub-limiting unit 151 to restrict its position relative to the bottom shell 13 in the radial direction of the receiving hole 133. The grounding pin 22 is also limited by a first sub-limiting unit 151 to restrict its position relative to the bottom shell 13 in the radial direction of the receiving hole 133.

[0067] In one embodiment, both the first sub-pin 21 and the grounding pin 22 are cuboid structures, and the first sub-hole 111 and the grounding sub-hole 112 are rectangular holes. The first sub-pin 21 can be limited to a certain extent by the hole wall of the rectangular hole. At this time, the first sub-limiting unit 151 includes a first limiting block and a second limiting block, which are located on opposite sides of the first sub-hole 111. When the first sub-pin 21 passes through the first sub-hole 111, it can be limited by the first limiting block and the second limiting block.

[0068] In one embodiment, the second sub-pin 31 is a cylindrical structure. In this case, the second limiting structure 16 includes a plurality of annular blocks, one of which surrounds the outside of the second sub-pin 31 to limit its movement.

[0069] like Figure 4 As shown, in one embodiment, the outer surface of the base 1 is also provided with a clearance hole 17, which surrounds the second through hole 12 to allow the mating member of the second specification pin unit 3 to be inserted. Specifically, the clearance hole 17 is provided on the second surface 132. In addition, the clearance hole 17 has a plurality of sub-clearance holes 171, and one sub-clearance hole 171 surrounds the outside of a second sub-hole 121.

[0070] like Figure 7As shown, in one embodiment, the plug 10 further includes an insulating filler block 18, which fills the receiving hole 133 and fixes the first-specification plug unit 2 and the second-specification plug unit 3 to the base 1. This allows the first-specification plug unit 2 and the second-specification plug unit 3 to be installed more securely in the base 1.

[0071] During the production process, the insulating filler block 18 can be a block obtained by applying glue to the base shell 13 and allowing the glue to cool. The cap 14 can be a block obtained by wrapping the base 1 with glue after the glue application is completed. In addition, in this method, before setting the insulating filler block 18, the first specification pin unit 2 and the second specification pin unit 3 need to be electrically connected to the corresponding cable 20. After the glue is applied, one end of the cable 20 is also covered by the insulating filler block 18 and the cap 14.

[0072] like Figure 4 As shown, in one embodiment, the side of the base 1 is also provided with a boss structure 19. After assembly, the cover 14 covers the boss structure 19, which makes the connection between the two more secure.

[0073] In one embodiment, the boss structure 19 is annular and has multiple bosses, each boss being spaced apart along the axial direction of the receiving hole 133, wherein the axial direction of the receiving hole 133 is the arrangement direction of the first surface 131 and the second surface 132.

[0074] In addition, the boss structure 19 may also be provided with at least one notch 191, which can divide the annular boss structure 19 into multiple segments.

[0075] like Figure 2 As shown, in one embodiment, the plug 10 further includes a temperature detector 5, which is disposed within the receiving hole 133 and is used to detect the temperature of at least one of the first-specification plug unit 2 and the second-specification plug unit 3. This allows for the output of a corresponding alarm signal when the temperature is too high, enabling appropriate control.

[0076] The temperature sensor can be a thermistor, etc.

[0077] like Figure 2 As shown, in one embodiment, the plug 10 further includes a micro switch 6, which is connected to the base 1 and is used to receive force applied by the mating plug 10 to control the on / off state of the two terminals of the micro switch 6.

[0078] The counterswitching component can be either a first or a second counterswitching component. In use, the two terminals of the microswitch 6 can be connected to an external control circuit to send corresponding control signals by switching these terminals on and off.

[0079] For example, in a practical application scenario, when the plug 10 is not mated with the mating component, the two terminals are disconnected. In this case, the corresponding control device can prevent power supply to the first-specification pin unit 2 and the second-specification pin unit 3. When the plug 10 is not mated with the mating component, the trigger part of the microswitch 6 can receive force applied to the mating component, connecting the two terminals. In this case, the corresponding control device can then supply power to the first-specification pin unit 2 and the second-specification pin unit 3. This design avoids adverse phenomena such as electric arcing when the plug 10 mates with the mating component, improving the safety of the plug 10.

[0080] like Figure 2 and Figure 4 As shown, in one embodiment, the plug 10 also includes a first signal terminal 7 and a second signal terminal, both of which are disposed within the receiving hole 133. A third through hole 134 and a fourth through hole 135 are also provided on the second surface 132, both of which communicate with the receiving hole 133. The first signal terminal 7 is used to connect a third pair of components through the third through hole 134, and the second signal terminal is used to connect a fourth pair of components through the fourth through hole 135.

[0081] In use, both the first signal terminal 7 and the second signal terminal can be connected to the same control circuit, and they can serve as two terminals in the open circuit region of the control circuit. The third and fourth pair of components are two conductive parts on the same conductive component. When the first signal terminal 7 is connected to the third pair of components and the second signal terminal is connected to the fourth pair of components, the control circuit is turned on, thus enabling corresponding control operations. For example, this can be used to determine whether the plug 10 is compatible with the pair of components.
