Description

Technical Field

[0001] This utility model relates to the field of high-voltage connector technology, and in particular to a high-voltage connector for automotive controllers. Background Technology

[0002] High-voltage connectors are functional components that connect, disconnect, or switch circuits and optical channels using electrical or optical signals and mechanical force. With the increasing popularity of new energy vehicles, the development and use of high-voltage connectors are growing. High-voltage connectors are mainly used in the high-voltage systems of electric vehicles, including the connection of components such as battery packs, motors, and charging interfaces. Their core function is to transmit high voltage and high current while ensuring safety and reliability. A high-voltage connector is a functional component that uses electrical signals or mechanical force to connect or disconnect circuits; it consists of a fixed-end electrical connector and a free-end electrical connector.

[0003] An existing high-voltage connector for automotive controllers is prone to loosening after the connection is completed during the actual installation and use of the equipment, thus affecting the stability of the connection. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-voltage connector for automotive controllers.

[0005] This utility model is achieved by the following technical solution: a high-voltage connector for an automotive controller, including a fixed horizontal plate, a positioning hole is provided inside the fixed horizontal plate, an installation sleeve is fixedly connected to the front of the fixed horizontal plate, and positioning plates are fixedly connected to both the left and right ends of the installation sleeve.

[0006] The upper and lower ends of the mounting sleeve are fixedly connected to limit support plates, and the upper and lower ends of the mounting sleeve are fixedly connected to limit locking blocks. A connector is fixedly connected inside the mounting sleeve. A fixing sleeve is fixedly connected to the rear end of the fixing cross plate. A mounting frame is fixedly connected inside the fixing sleeve. A limit locking plate is hinged inside the fixing sleeve. A toggle support plate is fixedly connected to the surface of the limit locking plate.

[0007] Through the above technical solution, the symmetrical layout of the positioning plate also makes the force evenly distributed, preventing the risk of deformation caused by local stress concentration.

[0008] As a further improvement to the above solution, the number of positioning plates is set to four, with two plates forming a group, and the four positioning plates are symmetrically distributed around the mounting sleeve.

[0009] Through the above technical solution, the positioning holes opened inside the fixed cross plate provide the reference coordinates for the whole device. Together with the four positioning plates symmetrically distributed on the left and right sides of the mounting sleeve, a multi-point positioning system is formed to ensure that the high-voltage connector is quickly aligned with the installation position in the car controller housing, avoid displacement caused by vibration or impact, and improve the stability of electrical connection.

[0010] As a further improvement to the above solution, the number of the limiting support plate and the limiting block is set to several, and the several limiting support plates and the limiting blocks are symmetrically distributed vertically around the mounting sleeve.

[0011] Through the above technical solution, several limiting support plates and limiting blocks symmetrically distributed at the upper and lower ends of the installation sleeve with the installation sleeve as the center form a double constraint mechanism in the vertical direction.

[0012] As a further improvement to the above solution, the connector is fixedly connected to the front of the fixed horizontal plate, the mounting frame is fixedly connected to the rear end of the fixed horizontal plate, and the limiting support plate is located on the front of the fixed horizontal plate.

[0013] The above technical solution limits the longitudinal movement range of the connector by limiting the support plate, while the limiting block prevents the connector from accidentally coming out by mechanical blocking. It is especially suitable for high-frequency vibration environments during vehicle operation, and greatly reduces the probability of poor contact or disconnection failure.

[0014] As a further improvement to the above scheme, the number of the limiting plate and the actuating support plate is set to two, and the two limiting plates and the actuating support plate are symmetrically distributed vertically around the fixed sleeve.

[0015] As a further improvement to the above solution, the rear end of the actuating support plate contacts the front surface of the mounting frame, the actuating support plate is located at the rear end of the fixed horizontal plate, and the limiting plate is located at the rear end of the fixed horizontal plate. Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features a connector that is directly fixed inside the mounting sleeve, its position strictly defined by a positioning system at the front end of the fixing plate, ensuring precise insertion with the automotive controller interface. The fixing sleeve at the rear end of the fixing plate has a built-in mounting frame, which achieves secondary locking through a hinged limiting plate. Combined with the operating handle of the support plate, this allows operators to quickly install and remove the connector without tools, balancing ease of operation with reliable locking.

[0017] This utility model features a limiting plate hinged inside a fixed sleeve, which can swing slightly with the connection action, compensating for installation errors while absorbing lateral vibration energy. By setting a contact design between the rear end of the toggle plate and the front of the mounting frame, a self-locking clamping structure is formed, which can maintain stable contact pressure even under extreme road conditions, effectively extending the service life of the connector and reducing maintenance frequency.

[0026] Please combine Figure 1-4 This embodiment of a high-voltage connector for an automotive controller includes a fixed horizontal plate 1, with a positioning hole 2 inside the fixed horizontal plate 1, and an installation sleeve 3 fixedly connected to the front of the fixed horizontal plate 1. Positioning plates 4 are fixedly connected to both the left and right ends of the installation sleeve 3.

A connector 7 is fixedly connected inside the mounting sleeve 3. A fixing sleeve 8 is fixedly connected to the rear end of the fixing cross plate 1. A mounting frame 9 is fixedly connected inside the fixing sleeve 8. A limit plate 10 is hinged inside the fixing sleeve 8, and a lever plate 11 is fixedly connected to the surface of the limit plate 10. The connector 7 is directly fixed inside the mounting sleeve 3, and its position is strictly limited by the positioning system at the front end of the fixing cross plate 1, ensuring precise insertion with the automotive controller interface. The mounting frame 9 is built into the fixing sleeve 8 at the rear end of the fixing cross plate 1. Secondary locking is achieved through the hinged limit plate 10. Combined with the operating handle of the lever plate 11, this allows operators to quickly install and remove the connector without tools, balancing operational convenience and locking reliability.

[0028] The symmetrical layout of the positioning plate 4 also ensures that the force is evenly distributed, preventing the risk of deformation caused by local stress concentration.

[0029] The number of positioning plates 4 is set to four, and each pair is a group of two. The four positioning plates 4 are symmetrically distributed on the left and right sides with the mounting sleeve 3 as the center.

[0030] The positioning holes 2 inside the fixed horizontal plate 1 provide a reference coordinate for the overall device. Together with the four positioning plates 4 symmetrically distributed on the left and right sides of the mounting sleeve 3, with the mounting sleeve 3 as the center, a multi-point positioning system is formed to ensure that the high-voltage connector is quickly aligned with the installation position in the car controller housing, avoid displacement caused by vibration or impact, and improve the stability of the electrical connection.

[0031] The number of limiting support plates 5 and limiting blocks 6 is set to several, and the several limiting support plates 5 and limiting blocks 6 are symmetrically distributed vertically around the mounting sleeve 3.

[0032] Several limiting support plates 5 and limiting blocks 6, which are symmetrically distributed at the upper and lower ends of the mounting sleeve 3 with the mounting sleeve 3 as the center, form a double constraint mechanism in the vertical direction.

[0033] The connector 7 is fixedly connected to the front of the fixed horizontal plate 1, the mounting frame 9 is fixedly connected to the rear end of the fixed horizontal plate 1, and the limiting support plate 5 is located on the front of the fixed horizontal plate 1. The limiting plate 10 is hinged inside the fixed sleeve 8 and can swing slightly with the connection action to compensate for installation errors and absorb lateral vibration energy. By setting the contact design between the rear end of the toggle support plate 11 and the front of the mounting frame 9, a self-locking clamping structure is formed, which can maintain stable contact pressure even under extreme road conditions, effectively extending the service life of the connector and reducing the frequency of maintenance.

[0034] The limiting support plate 5 restricts the longitudinal movement range of the connector 7, while the limiting block 6 prevents the connector 7 from accidentally coming out through mechanical blocking. It is especially suitable for high-frequency vibration environments during vehicle operation, and greatly reduces the probability of poor contact or disconnection failure.

[0035] The number of limit plates 10 and actuating support plates 11 is set to two, and the two limit plates 10 and actuating support plates 11 are symmetrically distributed vertically around the fixed sleeve 8.

[0036] The rear end of the actuating support plate 11 contacts the front surface of the mounting frame 9. The actuating support plate 11 is located at the rear end of the fixed horizontal plate 1, and the limiting plate 10 is located at the rear end of the fixed horizontal plate 1.

[0037] The implementation principle of a high-voltage connector for an automotive controller in this embodiment is as follows: the connector head 7 is directly fixed inside the mounting sleeve 3, and its position is strictly limited by the positioning system at the front end of the fixed cross plate 1 to ensure precise mating with the automotive controller interface. The mounting sleeve 8 at the rear end of the fixed cross plate 1 has a built-in mounting frame 9, which is locked in place by a hinged limiting plate 10. With the operation handle of the lever plate 11, the operator can quickly install and remove the connector without tools, balancing ease of operation and locking reliability. The limiting plate 10 is hinged inside the fixed sleeve 8 and can swing slightly with the connection action, compensating for installation errors while absorbing lateral vibration energy. The contact design between the rear end of the lever plate 11 and the front of the mounting frame 9 forms a self-locking clamping structure, which can maintain stable contact pressure even under extreme road conditions, effectively extending the service life of the connector and reducing maintenance frequency.
