Description

Technical Field

[0001] The present invention relates to an electrical connection device, and more specifically, to an angled connector, the application scenarios of which include high-voltage connectors on new energy vehicles. Background Art

[0002] At present, it has become a trend in the automotive industry that new energy vehicles (including pure electric vehicles and hybrid vehicles) replace traditional fuel vehicles. The automotive electronic and electrical architecture (EEA) of new energy vehicles is very different from that of traditional fuel vehicles, so the various connectors in the EEA of new energy vehicles are also different from or have never been used in the EEA of traditional fuel vehicles. For example, the EEA of new energy vehicles usually contains high-voltage connectors.

[0003] High-voltage connectors are also called high-voltage connectors. Generally, they refer to connectors with working voltages above 60V and are mainly responsible for transmitting high currents. They are mainly used in high-voltage and high-current circuits of electric vehicles, and work together with wires to transmit the capacity of the battery pack to various components in the vehicle system through different electrical circuits, such as motor controllers, DCDC converters, chargers, etc. Due to the high-voltage use environment, the high-voltage connectors have special indicators to meet in terms of heat resistance, pressure resistance, current carrying capacity, EMC and other physical properties.

[0004] For example, the Chinese patent with the authorization announcement number CN210576875U discloses a 90° elbow connector, a plug assembly and a socket assembly. The plug housing on the plug assembly and the socket housing on the socket assembly match and couple tightly. After connection, the signal terminal and the signal socket are connected to each other to achieve signal transmission. However, since one of the development trends of new energy vehicles is high integration and lightweight, the requirements for internal space are constantly increasing. In order to adapt to different wiring spaces, the connector needs to be able to adapt to different cable access angles more accurately, such as 45 degrees, 60 degrees, etc. Therefore, the demand for connectors at different angles is gradually increasing. In addition, the industry uses the connection between the terminal and the reed to achieve conduction and signal transmission, but the stability of the terminal and the reed after connection is limited. Because the pre-tightening force between the connected terminal and the reed is limited, the connection makes the terminal and the reed in active contact, which leads to a large contact resistance. As the temperature on the terminal and the reed increases, the mechanical properties will decrease, gradually leading to an increase in temperature rise. That is to say, the temperature of each component in the electronic and electrical equipment will gradually increase above the environment, and the conductivity will be relatively reduced, causing the entire elbow connector to be in a state of long-term thermal fatigue. Long-term thermal fatigue causes the performance of the elbow connector to decrease. Summary of the invention
