Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a high-voltage connector for electric vehicles. Background Technology

[0002] Connectors are key components in electronic systems used to achieve separable connections between circuits. Their core function is to transmit electrical energy, signals, or data, and to ensure the reliability and stability of the connection. High-voltage connectors refer to connectors with AC voltage above 1000V or DC voltage above 1500V, and are mainly used in electric vehicles, charging facilities, industrial equipment, medical equipment, etc.

[0003] A search revealed that patent application number 202320896401.4 discloses a high-voltage connector for electric vehicles that is easy to connect, including a left connector, a right connector and a connecting wire. The left connector is connected to the right connector via the connecting wire. One end of the left connector is provided with two left pins, and one end of the right connector is provided with two right pins.

[0004] Although the easy-to-connect electric vehicle high-voltage connector can protect the plug pins at both ends of the connector from collisions through the first and second plastic protective shells, the plastic protective shells of the easy-to-connect electric vehicle high-voltage connector cannot prevent dust or external water from contacting the pins, and the protection effect is poor.

[0005] Therefore, we propose a high-voltage connector for electric vehicles. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-voltage connector for electric vehicles, which solves the problem that the plastic protective shell of existing devices cannot prevent dust or external water from contacting the pins, resulting in poor protection.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-voltage connector for electric vehicles, comprising a connecting wire, both ends of which are connected to connector heads, and the connector head having a pin at the end furthest from the connecting wire;

[0008] The connector has a circular cross-section, and a protective shell is provided on the outer surface of the connector.

[0009] The protective housing includes a protective housing that is movably fitted onto the outer surface of the connector. A protective cover is hinged to the side of the protective housing away from the connecting line via a hinge. A magnetic block is fixedly installed on the bottom side of the protective cover near the protective housing. Both the protective housing and the protective cover are made of martensitic stainless steel. A ring magnet is fixedly fitted onto the end of the outer surface of the connector away from the connecting line. The ring magnet is located inside the protective housing.

[0010] Preferably, a silicone pad is adhered to the outer surface of the annular magnet, and an annular sealing gasket is adhered to the surface of the protective shell and the protective cover. The silicone pad can protect the annular magnet, and the annular sealing gasket can increase the sealing between the protective shell and the protective cover.

[0011] Preferably, a reinforcing sleeve is fixedly installed at one end of the connector that connects to the connecting wire. The reinforcing sleeve is fixedly fitted onto the outer surface of the connecting wire. The connector is made of rubber. The reinforcing sleeve can increase the strength of the connection between the connecting wire and the connector, and at the same time, can prevent the two ends of the connecting wire from breaking due to long-term bending.

[0012] Preferably, the connecting line includes a conductor, the outer surface of which is fitted with an inner rubber layer, the outer surface of which is fixedly fitted with a metal foil layer, and the outer surface of which is fixedly fitted with a metal mesh layer. The metal foil layer forms a conductive barrier through its continuous metal surface. When electromagnetic waves reach the surface of the metal foil layer, most of the energy is directly reflected, and the remaining part is converted into heat energy and absorbed at the material surface due to resistance loss, thereby weakening the intensity of the electromagnetic waves. The metal mesh layer forms an induced current through the closed loop of the mesh conductor, generating a reverse magnetic field to cancel the original magnetic field.

[0013] Preferably, the metal foil layer is made of copper, and the metal mesh layer is woven from aluminum wire. The metal foil layer and the metal mesh layer can shield the interference of external electromagnetic waves on the current in the conductor.

[0014] Preferably, an asbestos fireproof layer is fixedly fitted on the outer surface of the metal mesh layer, and an outer rubber layer is fixedly fitted on the outer surface of the asbestos fireproof layer. The asbestos fireproof layer can provide fireproof and wear-resistant protection for the wires.

[0015] This utility model provides a high-voltage connector for electric vehicles. It has the following advantages:

[0016] 1. The high-voltage connector of this electric vehicle uses a magnetic block to attach the protective cover to the end face of the protective shell, which can protect the pins and prevent external dust and water from contacting the pins, thus increasing the service life of the connector. The pins can be exposed by moving the protective shell along the surface of the connector head, so as to connect the pins to external components. It is simple and convenient to use and has a good protective effect on the pins. It solves the problem that the plastic protective shell of the existing device cannot prevent dust or external water from contacting the pins and has a poor protective effect.

[0017] 2. The high-voltage connector of this electric vehicle, through the setting of metal foil layer and metal mesh layer, can avoid the interference of external electromagnetic waves on the current in the wire, so as to improve the stability of the connector during use. The asbestos fireproof layer can protect the wire from fire and wear. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] like Figure 1-4As shown: The system includes a connecting wire 1, with connectors 2 connected to both ends. A pin 21 is located at the end of connector 2 furthest from connecting wire 1. Connector 2 has a circular cross-section. A protective shell 3 is provided on the outer surface of connector 2. The protective shell 3 includes a protective cover 31 movably fitted onto the outer surface of connector 2. A protective cover 32 is hinged to the side of protective cover 31 furthest from connecting wire 1. A magnet 33 is fixedly installed on the bottom side of the protective cover 32 near the protective cover 31. Both protective shell 31 and protective cover 32 are made of martensitic stainless steel. A ring magnet 34 is fixedly fitted onto the outer surface of connector 2 furthest from connecting wire 1. The ring magnet 34 is located inside the protective shell 31. A silicone pad is adhered to the outer surface of the connector 34. An annular sealing gasket is adhered to the surface of the protective shell 31 and the protective cover 32. A reinforcing sleeve 22 is fixedly installed at the end of the connector 2 that is connected to the connecting wire 1. The reinforcing sleeve 22 is fixedly fitted on the outer surface of the connecting wire 1. The connector 2 is made of rubber. The protective cover 32 is attracted to the end face of the protective shell 31 by the magnetic block 33, which can protect the pin 21 and prevent external dust and water from contacting the pin 21, which helps to increase the service life of the connector. The pin 21 can be exposed by moving the protective shell 31 along the surface of the connector 2, so that the pin 21 can be connected to external components. It is simple and convenient to use and has a good protective effect on the pin 21.

[0026] Example 2:

[0027] like Figure 1 , 2 As shown in Figure 4: the connecting wire 1 includes a conductor 11, an inner rubber layer 12 sleeved on the outer surface of the conductor 11, a metal foil layer 13 fixedly sleeved on the outer surface of the inner rubber layer 12, a metal mesh layer 14 fixedly sleeved on the outer surface of the metal foil layer 13, the metal foil layer 13 is made of copper, the metal mesh layer 14 is woven from aluminum wire, an asbestos fireproof layer 15 fixedly sleeved on the outer surface of the metal mesh layer 14, and an outer rubber layer 16 fixedly sleeved on the outer surface of the asbestos fireproof layer 15. The metal foil layer 13 and the metal mesh layer 14 can prevent external electromagnetic waves from interfering with the current in the conductor 11, so as to improve the stability of the connector during use. The asbestos fireproof layer 15 can provide fireproof and wear-resistant protection for the conductor 11.

[0028] The working principle and usage process of this utility model: The high-voltage connector of this electric vehicle uses a magnetic block 33 to attract the protective cover 32 to the end face of the protective shell 31, thereby protecting the pin 21 and preventing external dust and water from contacting the pin 21. When it is necessary to connect the pin 21 to an external component, the protective shell 31 can be pulled backward, and then the protective shell 31 moves along the surface of the connector 2. During this process, the pin 21 contacts the side wall of the protective cover 32 and pushes it open. Then the protective cover 32 flips upward and opens until the protective cover 32 moves to the right side of the annular magnet 34. Then the magnetic block 33 and the annular magnet 34 are attracted together, thereby limiting the position of the protective cover 32 and the protective shell 31. Then the pin 21 can be connected to the external component. The metal foil layer 13 and the metal mesh layer 14 can shield the interference of external electromagnetic waves on the current in the conductor 11.
