Description

Technical Field

[0001] This invention belongs to the field of connector technology for new energy electric vehicles, specifically relating to a socket connector and a high-voltage connector. Background Technology

[0002] Connectors, as a convenient connection component, have been widely used in various industries. Common connectors include plugs and sockets, which usually contain housings. The plug and socket are connected by mating through the guide of the housing.

[0003] With the development of the new energy vehicle industry, the electrical functions are becoming increasingly complex and numerous, and the shielding performance requirements of the entire electric vehicle are also becoming higher and higher. In order to ensure the sealing effect of the connector mating, the current connectors usually have two seals. The first is the seal between the socket and the equipment panel. The second is because the socket usually includes a socket housing. After the plug and socket are mated, they need to be sealed. In order to complete the sealing between the plug and the socket, the existing socket housing generally has a relatively large mounting surface. The interface rubber ring groove and mounting screw holes are arranged on the mounting surface, and the interface rubber ring is set in the interface rubber ring groove. This makes the overall size of the connector larger, with more assembly processes and higher manufacturing costs. Summary of the Invention

[0004] The purpose of this invention is to provide a socket connector and a high-voltage connector, which directly mounts the socket insulator on the device panel. When sealing with the plug, the socket housing and socket end interface rubber ring are no longer required, greatly reducing the connector size and lowering production costs.

[0005] The technical solution adopted by the present invention to achieve the above objectives is as follows:

[0006] A socket connector includes a socket end insulator for direct mounting on a mounting panel and mating with a plug insulator. The socket end insulator has a socket end contact that mates with a plug end contact. A socket end metal plate is provided connecting the socket end contact.

[0007] As a preferred embodiment of the present invention, the socket end insulator is provided with a first mounting hole for fixing the socket end insulator to the mounting panel by means of screws.

[0008] As a preferred embodiment of the present invention, the metal plate at the socket end is provided with a second mounting hole for fixing the conductive element to the metal plate at the socket end by screws.

[0009] As a preferred embodiment of the present invention, the metal plate at the socket end is provided with steps for locking and installing the socket end contact.

[0010] As a preferred embodiment of the present invention, the two side walls of the socket end insulator at the socket end contact point are both continuously closed and non-open.

[0011] In a preferred embodiment of the present invention, the socket end insulator is integrally formed with the device panel.

[0012] As a preferred embodiment of the present invention, the socket end insulator is provided with a double-spring double-ended socket.

[0013] As a preferred embodiment of the present invention, the socket end contact is provided with a contact insulator, and a temperature sensor is provided on the contact insulator.

[0014] A high-voltage connector includes a plug connector and a socket connector according to any of the above embodiments. The plug connector includes a plug housing. The end face of the plug housing for mating with the socket connector is provided with a rubber ring groove. The rubber ring groove is provided with an interface rubber ring that seals the plug housing and the mounting panel when the plug connector and the socket connector are mated and engaged, and when the plug housing and the mounting panel are pressed together.

[0015] As a preferred embodiment of the present invention, the plug housing is provided with a plug end insulator, a plug shield is provided between the plug end insulator and the plug housing, a plug end contact is provided inside the plug end insulator, and an outer shielding ring, an inner shielding ring, a wire seal and a tail cap are provided in sequence inside the plug housing away from the plug end insulator.

[0016] Beneficial effects of this invention:

[0017] 1. In the socket connector of the present invention, the socket insulator is directly disposed on the mounting panel. Compared with the existing socket connector, there is no socket housing. Correspondingly, there is no need to set the socket end interface rubber ring, which reduces the types and volume of connector parts, reduces the assembly process, and greatly reduces the connector production cost.

[0018] 2. The connector of the present invention uses a socket connector to be directly fixed to the mounting panel. Compared with the existing socket connectors that use a shell for mating, it only requires one interface rubber ring, while also reducing the contact resistance of the connector and improving the shielding effect of the connector.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. In the description of the present invention, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention 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, and therefore should not be construed as a limitation of the present invention.

[0028] Combination Figure 1 As shown, the technical problems existing in the existing connectors are further explained. When existing plug connectors and socket connectors are mated, in order to ensure the sealing effect of the connector mating, an interface rubber ring is usually set between the plug housing 1 and the socket housing 4 for sealing, and an interface rubber ring is set between the socket housing 4 and the mounting panel 5 for sealing. The socket housing is large in volume and requires rubber ring grooves and mounting screw holes. The connector assembly process is complicated and the manufacturing cost is high. The present invention is to solve these problems existing in the existing connectors.

[0029] This invention provides a first embodiment of a socket connector.

[0030] Combination Figures 2 to 4 As shown, the socket connector in this embodiment includes a socket end insulator 6, which is directly mounted on the mounting panel 5. During use, the socket end insulator 6 engages with the plug insulator of the plug connector. The socket end insulator 6 has a cavity, within which a socket end contact 7 is provided. After the plug connector and socket connector are engaged, the socket end contact 7 engages with the plug end contact 102 of the plug connector for electrical connection. A socket end metal plate 8 is provided connecting the socket end contact 7.

[0031] The socket end insulator 6 has a first mounting hole 601. The first mounting hole 601 facilitates fixing the socket end insulator 6 to the mounting panel 5 with screws. The shape, position and number of the first mounting holes 601 can be adjusted according to actual needs. Understandably, the socket insulator 6 can also be made directly as a single piece with the mounting panel 5.

[0032] A second mounting hole 802 is provided on the metal plate 8 at the socket end. The second mounting hole 802 facilitates the fixing of conductive parts such as wires to the metal plate 8 at the socket end by screws. Understandably, the shape, position and number of the second mounting hole 802 can also be adjusted according to actual needs.

[0033] In this embodiment, the socket connector only needs to be provided with the socket end insulator 6. After assembling the socket end contact 7 and the socket end metal plate 8, a complete socket connector can be formed. There is no need to provide a socket housing, which greatly reduces the types and volume of socket connector parts, reduces assembly steps, and lowers the production cost of socket connector.

[0034] In addition, the main body of the socket connector is the socket insulator. Without a socket housing, the reduction in parts further reduces the gap between the parts, greatly enhancing the vibration resistance of the socket connector.

[0035] In this embodiment, when assembling the socket end contact 7, steps 801 are provided opposite to each other on the socket end metal plate 8, and mounting grooves for locking and installing the socket end contact 7 are formed between the steps 801. There is no need to add a new insulator to fix the socket end contact 7, the assembly structure is simple and the manufacturing cost is low.

[0036] Combination Figure 4 As shown, the two side walls of the socket end insulator 6 at the location where the socket end contact 7 is installed are continuously closed and non-open, which can reduce the risk of insulation failure between the socket end contact 7 and the inner wall of the mounting panel 5.

[0037] This embodiment also provides a high-voltage connector:

[0038] The high-voltage connector in this embodiment includes a plug connector and a socket connector, wherein the socket connector adopts the socket connector provided by this invention, combined with... Figure 5 As shown, the plug connector includes a plug housing 1. The end face of the plug housing 1 for mating with the socket connector is provided with a rubber ring groove 2. An interface rubber ring 3 is provided in the rubber ring groove 2. When the plug connector and the socket connector are mated and engaged, and under the pressure of the plug housing 1 and the mounting panel 5, the interface rubber ring 3 can seal the space between the plug housing 1 and the mounting panel 5.

[0039] The plug connector can be an existing plug connector, based on... Figure 5 As shown, in this embodiment, the plug housing 1 is provided with a plug end insulator 101, a plug shield 105 is provided between the plug end insulator 101 and the plug housing 1, a plug end contact 102 is provided inside the plug end insulator 101, and an outer shielding ring 104, an inner shielding ring 103, a wire seal 106 provided by a wire seal baffle 107, and a tail cap 108 provided at the tail of the plug housing 1 are also provided in sequence outside the plug end insulator 101.

[0040] The high-voltage connector in this embodiment, compared to existing socket connectors that use a housing for mating, only requires an interface rubber ring between the plug housing and the mounting panel to achieve effective sealing. This reduces the number of assembly parts and processes, thus lowering manufacturing costs. Furthermore, when using a socket housing in the traditional way, the contact resistance of the connector consists of three parts: the resistance between the plug shield and the socket shield, the resistance between the cable shield and the plug shield, and the resistance between the socket shield and the main components. By using a socketless design, some of these resistances are eliminated, thereby reducing the contact resistance of the connector and improving its shielding effect.

[0041] This invention provides a second embodiment of a socket connector.

[0042] As mentioned above, the socket connector of the present invention mainly eliminates the socket housing and the socket end interface rubber ring, and directly fixes the socket insulator to the mounting panel. In terms of specific implementation, it is not limited to the socket connector provided in Embodiment 1.

[0043] In this embodiment, combined with Figure 6 and Figure 7As shown, a double-spring double-ended socket 602 can be provided on the socket end insulator 6. The position of the double-spring double-ended socket 602 on the socket end insulator 6 can be set as needed. The shape of the socket end contact 7 can also be set as needed to be straight or bent. A nut 702 can be set in conjunction with the socket end contact 7 to connect the wires. A contact insulator 701 can also be provided on the socket end contact 7. A temperature sensor 703 is provided on the contact insulator 701. The temperature sensor 703 can be installed on the contact insulator 701 by screws. The temperature sensor 703 is used to control the temperature of the socket connector.

[0044] It should be noted that the parts not described in detail in this article are prior art. The above embodiments are only used to illustrate the present invention, but the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
