𐄀 Technology Connection to Future
In the field of electric vehicles, Yonggui provides the whole solution of high voltage, large and small current interconnection system. Main products: high-voltage interconnection system connectors and harness components, high-voltage power distribution box, etc.The products adopt ultrasonic welding, high-speed punching terminals and other process technologies to realize lightweight products. On the basis of IATF 16949 system, the introduction of VDA system, MES system, automation, integration of electrical performance testing and other process control methods, as well as dust-free workshop and other modern production environment, to provide strong quality assurance for the products.
Connectors for new energy vehicles play a key role in power transmission, data communication and control systems. To ensure the reliability and performance of new energy vehicles, the maintenance and durability of vehicle connector are critical.
Regular inspection and cleaning
Tightening and plug-in precautions
Keep dry
Number of plugs and unplugs
Material quality
Design optimization
When selecting connectors for electric vehicles, a number of factors such as the type of connector required, environmental requirements, and performance specifications need to be considered to ensure that it meets the requirements of a particular application. After determining the type product, you can then refer to the following parameters for selection:
The maximum voltage at which electrical equipment (including power-using and power-supplying equipment) can work stably for a long period of time.
The maximum current allowed to pass for a long period of time when the heat generation does not exceed the permissible temperature for long-term heat generation under the operating conditions of the rated voltage at the reference ambient temperature.
Mainly refers to the electrical connector plug tail cable outlet and socket installation panel direction between the angle. Commonly, there are 90-degree (curved) and 180-degree (straight) out of the electrical connector.
In the development of new energy vehicles in recent years, automotive high-voltage connectors are gradually separated from the traditional high-voltage high-current and traditional low-voltage automotive connectors.
Compared with the traditional high-voltage high-current connectors, the use of connectors for new energy vehicles is more complex and changeable working conditions, the reliability of the connector requirements are also higher. Due to the increase in voltage level (the current mainstream system voltage ≥ 300V DC), the connector's safety requirements are higher, and accordingly, the insulation and protection requirements of the product have been improved.
