Description

energy storage connector

The invention relates to an energy storage connector, especially an energy storage connector that can be fixed at multiple angles.

Electrical connectors refer to connecting components and accessories used for electronic signals. The cables and electrical connectors are used to convert and transmit signals between electronic devices. In other words, the electrical connectors are also bridges between signals. Electrical connectors are widely used in automotive and computer peripheral applications, communication data applications, industry, military aerospace, transportation, consumer electronics, medical, instrumentation, commercial equipment, etc., so they play an important role in various fields.

RF coaxial connector (PAL connector) is one of the commonly used types of electrical connectors, and is also used in electronic control modules (MCU), motors, batteries, on-board chargers, etc. PAL connectors are also often used in energy storage devices. Since the energy storage cabinet of the energy storage power station has a good volume utilization rate, electrical connectors are more widely used in the energy storage cabinet. The main components contained in the energy storage cabinet are power electronic devices such as batteries, inverters, and cables. Generally speaking, the batteries in the energy storage cabinet need to be grouped into battery modules, and multiple battery modules are then combined by electrical connectors to form an energy storage system. However, in this era when the signal transmission speed continues to be high-speed, people put forward more requirements on the volume and energy density of the energy storage cabinet. Therefore, connecting each battery module The demand for sets of electrical connectors continues to increase.

The energy storage connector usually includes a plug and a matching socket, and the electrical connection of the electronic product is realized by plugging the plug and the socket into each other. Since the battery modules of the energy storage device are numerous and closely arranged, the energy storage connectors need to be arranged at different angles to connect the battery modules. Furthermore, general energy storage connectors are connected at a single angle. Therefore, when adjusting the angle of the energy storage connector, the user needs to remove the socket from the battery module first, and then adjust the socket to the required angle before reinstalling it. The socket is installed on the battery module, thereby reducing convenience. In addition, the energy storage connector is usually connected to each battery module from the outside, and there is still a gap after the plug and the socket of the energy storage connector are connected. Therefore, moisture or other substances may penetrate the plug and socket through the gap and affect the terminals, causing short circuits and sparks, thereby reducing the safety of the equipment.
