Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to an integrated wiring port structure, a discharge socket, and a wall socket structure. Background Technology

[0002] Existing AC charging and discharging equipment for electric vehicles typically uses a single-phase, two-pole, grounded plug for household or similar applications to connect to an external socket for charging or discharging. Currently, there are various specifications for single-phase, two-pole, grounded sockets for household and similar applications in my country, including 10A, 16A, and 32A. Therefore, electric vehicle manufacturers or AC charging and discharging equipment manufacturers can only choose one type of plug when designing their equipment. This results in poor compatibility during use, requiring an external adapter to adapt to different socket specifications, leading to a poor user experience.

[0003] Meanwhile, there is a significant difference in charging efficiency between 7kW (32A) AC charging equipment for electric vehicles and 3.5kW (16A) and 2.5kW (10A) AC charging equipment. Users generally prefer to use faster 7kW charging equipment. However, if it is a 7kW charging equipment, the plug of the charging equipment is often an industrial plug specification. Therefore, the charging equipment can only be used in its own dedicated socket and cannot be used elsewhere (because it is difficult to find a matching socket elsewhere). This causes a contradiction between charging efficiency and charging compatibility for users. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an integrated wiring port structure, a discharge socket, and a wall socket structure, which mainly provides connection terminals for at least two current specifications and is set on the same fixed end face, enabling the connection of plugs with different specifications.

[0005] The technical solution adopted in this utility model is as follows:

[0006] In the first aspect, this utility model provides a multi-specification integrated connection port structure for connecting plugs of corresponding multiple specifications to achieve electrical connection. It includes a fixed end face, and the fixed end face is provided with connection ends of at least two current specifications. At least one connection end is recessed into the fixed end face to form a groove structure, and at least one connection end carries a current specification greater than 16A.

[0007] In conjunction with the first aspect, this utility model provides a first embodiment of the first aspect, wherein the connecting ends are all groove structures that are recessed inward and inserted into the fixed end face.

[0008] The so-called "intercalation setting" refers to the fact that the connection end of the slot structure is generally set in a unified three-wire configuration according to the current specification, that is, it has at least three ports for connecting the neutral wire, the live wire and the ground wire. There is a certain gap between the different ports belonging to the same connection end, so the ports of different specifications of connection ends can be intercalated using this gap. When forming a standard specification connection end, the area required for the fixed end face can be reduced.

[0009] This recessed design allows for the connection of various single-prong plugs of different specifications, such as 10A, 16A, 32A, and 64A, all of which can be inserted into the wiring port structure to achieve electrical connection.

[0010] In conjunction with the first aspect, this utility model provides a second embodiment of the first aspect, wherein at least one connecting end protrudes outward from the fixed end face.

[0011] The terms "protrusion" and "recess" generally refer to the distinction between male and female connectors. Because this electrical connection structure is typically a plug-in connection, unlike low-power touch connections, all connection terminals involved in this application must meet the male / female connector requirements. Since compatibility with multiple current specifications is required for the wiring port, there are two methods: either the plug adapts to a special wiring port and a commonly used existing wiring port of a primary specification, or the wiring port itself has multiple female connector structures, enabling compatibility with connections of independent plugs of different specifications, as described in the above embodiments. However, the embodiment mentioned having at least one male connector means that this wiring port structure cannot adapt to existing single-specification plugs, but can only adapt to the same multi-specification plug structure.

[0012] In conjunction with the first aspect, this utility model provides a third embodiment of the first aspect, in which all connection ends are connected to the same wire harness to form an equipotential state, and at least two connection ends form a parallel relationship when an external plug is connected.

[0013] It's worth noting that the so-called parallel connection refers to a connection structure where the external plugs, originally forming independent connections, achieve equipotentiality through a set of conductors within the terminals. For example, in three-prong terminals with current ratings of 10A and 32A, the neutral, live, and ground wires are all internally connected and linked to the external circuit via the same set of cables. When an external plug has conductors simultaneously connected to both terminals, the two terminals form a continuous parallel connection.

[0014] In conjunction with the second embodiment of the first aspect, this utility model provides a third embodiment of the first aspect, wherein all protrusions are cylindrical hollow tube structures, and the interior is provided with a metal collar for connecting an external insert to form an electrical connection.

[0015] In conjunction with the first aspect, this utility model provides a fourth embodiment of the first aspect, including a first connection end with a three-prong specification of 10A or 16A, the first connection end being an inwardly recessed three-prong hole; and a second connection end with a current specification greater than 16A, the second connection end being a columnar hollow tube structure protruding outward from the fixed end face.

[0016] In conjunction with the first aspect, this utility model provides a fifth embodiment of the first aspect, wherein the fixed end face is provided with a recessed groove for accommodating and wrapping the plug, and all connecting ends are disposed in the recessed groove.

[0017] Secondly, this utility model provides a discharge socket with a multi-specification integrated connection port structure on its end face, and also has several plug holes for connecting electrical equipment.

[0018] Thirdly, this utility model provides a wall socket structure with an end face having the aforementioned multi-specification integrated connection port structure.

[0019] The beneficial effects of this utility model are as follows:

[0020] (1) This utility model is compatible with plugs of various current specifications by having two or more types of connection terminals. It can meet the current specifications that have a wide range of connection bases in daily life, and at the same time, it can achieve dedicated high current specifications. All of them are fixed connection methods, small in size, low in cost and high in reliability.

[0021] (2) This utility model uses an internally integrated conductor structure design, that is, all the connection ends of the plug are energized when charging or discharging, and form a parallel current splitting effect by connecting at the same time. This not only avoids the impact of the maximum current limit on the efficiency of connection ends of different specifications, but also reduces the specification requirements and thus reduces the cost according to the setting requirements. Compared with the capacity required by a single connection end with the maximum current specification, this multi-connection parallel method can reduce the specification requirements.

[0035] Example 1:

[0036] This embodiment discloses a multi-specification integrated wiring port, mainly used for conductive connection structure. As a fixed structure for connecting plug 1, one end of the wiring port structure is connected to an external circuit through a conductor, and the other end is connected to an external plug 1. The plug 1 serves as the end of an electrical appliance or cable and is connected to the wiring port in this embodiment to form an electrical connection.

[0037] Specifically, the multi-specification integrated wiring port of this embodiment includes a fixed end face for the external plug 1 to be fitted and connected. It also includes at least two connection terminals of different current specifications disposed on the fixed end face, each with an independent inner conductor for connecting to an external circuit. Each connection terminal has at least one set of groove structures recessed into the fixed end face for engaging and securing the pins on the plug 1.

[0038] The plug 1 is inserted from the front of the fixed end face. The plug 1 also has at least one set of pins for insertion into the recessed connection end. In this embodiment, both the plug 1 and the wiring port adopt a one-way three-wire AC power specification, that is, a one-way neutral wire, a live wire, and a ground wire. Each connection end has three ports, and the corresponding set of pins or recessed connection structure of the plug 1 also has three pins.

[0039] In some embodiments, all connection ends on the fixed end face are recessed groove structures, including a 10A or 16A three-prong port as the first connection end 5. Corresponding inner conductors are provided inside the fixed end face, representing the neutral, live, and ground wires, respectively. Connection to an external power supply line is achieved by connecting the inner conductors with a cable. It also includes a 32A non-standard groove structure as the second connection end 4, which also corresponds to a different three-wire inner conductor than the first connection end 5.

[0040] In this embodiment, to reduce size and improve integration, three circular holes are provided between the gaps in the three-prong structure of the first connecting end 5. These circular holes constitute the second connecting end 4, serving as insertion holes within the gaps of the first connecting end 5, thus improving overall integrity and saving space. This wiring port can be used as a port for a discharge power strip specifically for new energy vehicles, used to connect the vehicle's discharge cable. One end of the discharge cable is the plug 1, which can include two types: a conventional 10A or 16A three-prong structure that can be inserted into the first connecting end 5 of this wiring port, and a 32A non-standard plug 1 that can also be inserted into the second connecting end 4 of the wiring port. Simultaneously, this wiring port can also be configured as a wall socket structure, compatible with various types of ordinary plug 1, such as independent 10A, 16A, and 32A plugs 1.

[0041] In some implementations, the existing plug 1 structure has a special design, namely a charging and discharging cable for new energy vehicles, one end of which is connected to the vehicle, and the other end is a special plug 1 design. It has a conventional outward protruding three-prong structure to meet the current specification of 10A or 16A and can be inserted into a normal socket for charging. At the same time, it has a set of recessed slot structures to meet the connection of special terminals of 32A or 64A. Since this plug 1 needs to be compatible with existing conventional sockets, it can only protrude with the commonly used three-prong standard, while the non-standard standard pins of 32A or 64A are recessed to avoid obstruction.

[0042] In this embodiment, the wiring port is provided with a first connecting end 5 for receiving the insertion of a three-prong plug, and a set of three cylindrical hollow second connecting ends 4, arranged in a triangular shape and protruding from the fixed end face within the gap of the first connecting end 5. The second connecting ends 4 have an inner conductor structure with a metal sleeve. Three corresponding circular slots are provided in the three-prong gap of the plug 1, and metal inserts are provided within the circular slots. The second connecting ends 4 are inserted into the circular slots so that the inner conductor of the metal sleeve covers the insert, achieving a conductive connection.

[0043] Furthermore, refer to Figures 1-4 In this embodiment, the wiring port is applied to a discharge socket 2 as a plug 1 structure for connecting the charging and discharging cable, thereby realizing the discharge function of vehicle power supply.

[0044] Reference Figure 1 and Figure 3 The wiring port is located on the left side. There is a groove 3 on the left surface of the discharge plug. The bottom of the groove 3 is the fixed end face. The fixed end face is provided with a first connecting end 5 with three inward recesses. In this embodiment, it is a 10A specification. The three cylindrical structures that protrude outward are the second connecting ends 4. The second connecting ends 4 are inserted into the gap of the first connecting ends 5.

[0045] Reference Figure 2 As can be seen, the plug 1 has three prongs and a recessed circular groove corresponding to the second connecting end 4. The insert in the circular groove corresponds to the inner conductor of the metal sleeve. Since the plug 1 is connected to the vehicle, after being inserted into the wiring port of the discharge socket, the three prongs and the middle insert are simultaneously electrically connected to the inner conductors corresponding to the first connecting end 5 and the second connecting end 4 in the discharge socket 2. At this time, the inner conductors with the same properties inside the discharge socket are also electrically connected. That is, the inner conductors of the live wire, neutral wire and ground wire of the first connecting end 5 and the second connecting end 4 are all in an equipotential relationship, and are powered through a set of cables to several sockets on the right side of the discharge socket.

[0046] This configuration allows the first connection terminal 5 and the second connection terminal 4 to form two parallel lines after connection with the vehicle, effectively shunting the current. In practice, the second connection terminal 4 is used as the highest specification, with its inner conductor capable of handling a maximum current of 32A. However, since the vehicle defaults to discharging only at a maximum of 32A at 7kW, the first connection terminal 5 shunts the current. By setting an appropriate inner conductor cross-sectional size, the maximum current shunted on the second connection terminal 4 line is limited to 22A, thus reducing the size of the inner conductor and lowering costs. Even if the second connection terminal 4 alone carries a current specification of 32A, the total current can be increased, enhancing its carrying capacity.

[0047] Furthermore, refer to Figure 5 In this embodiment, the wiring port is also applied to a wall socket. The center of the wall socket end face is also provided with a groove. The bottom of the groove is a fixed end face. The fixed end face is provided with a first connection end 5 and a second connection end 4. The outer side of the groove is the wall socket panel 6.

[0048] The wall socket structure has an inner conductor that connects to an external charging line via a cable, while plug 1 connects to the wall socket for charging the vehicle. Similarly, this wall socket can achieve a maximum charging current of 32A and a power of 7KW, which is the standard currently being promoted.

[0049] Furthermore, signal contacts are provided on plug 1 and on the fixed end face. As a low-voltage signal circuit, the signal contacts form a closed loop with a specific resistance value. When plug 1 is inserted into a power strip or wall socket, the vehicle identifies whether it is charging or discharging by the conductivity resistance of the signal contacts.

[0050] This utility model is not limited to the optional embodiments described above, and anyone can derive other various forms of products under the guidance of this utility model. The specific embodiments described above should not be construed as limiting the scope of protection of this utility model. The scope of protection of this utility model shall be determined by the claims, and the description can be used to interpret the claims.
