In the field of photography, a DV (Digital Video) camera needs a battery to supply power to the camera itself, and also needs to supply power to auxiliary devices such as lights and a focus follower installed near the camera during shooting, and power supply interfaces of the auxiliary devices are sometimes not uniform, so that the battery of the DV camera needs more power supply interfaces.

Currently, the auxiliary interfaces of the DV camera battery mainly include a B-TYPE port (or called D-TAP port), a DC port, a USB-a port, a USB TYPE-C port (or called TYPE-C port), and the like. The most applied is the B-type port, so the DV camera batteries on the market are mostly collocated by the auxiliary interfaces of B-type port + DC port, or B-type port + USB-a port. Of course there are also applications for separate auxiliary interfaces.

With the increasing application of USB TYPE-C, the european union committee also proposed a protocol plan in 2021 to unify charging interfaces of consumer electronic devices such as mobile phones and tablet phones into USB TYPE-C, and the USB TYPE-C interfaces will be more widely applied to various electronic products in the future, and may be used for charging and discharging, and also for signal transmission.

Because the USB TYPE-C hardware circuit arrangement needs a certain space, the space of the DV camera battery is limited, and the length and width dimensions cannot be increased due to the standard limitation of the camera battery bin. Therefore, the DV camera battery in the market is not provided with the USB TYPE-C interface, or the USB TYPE-C interface is independently arranged, and other interfaces are abandoned, especially the B-TYPE interface which is widely applied in the prior art.

This obviously does not meet the needs of the user, and for this reason, an effective solution is necessary.
