This application provides an optical module unlocking apparatus, an optical module, and an optical communication device. The optical module unlocking apparatus includes: a housing, including a base and a mounting portion connected to one end of the base, where the base is provided with an accommodation area for installing a circuit board and a component, and the mounting portion is provided with at least one optical port for connecting an optical cable; an unlocking component, including an unlocking arm movably connected to the housing, where the unlocking arm is provided with an abutment portion for abutting against an elastomer of a cage, and the unlocking component is configured to push the unlocking arm outwards relative to the housing in an insertion direction under an action of external force, to separate the abutment portion from the elastomer; and an elastic component, disposed on an outer side surface of the mounting portion and outside the accommodation area, where two ends of the elastic component are respectively connected to the mounting portion and the unlocking component. This can avoid occupying installation space of a circuit structure, increase a volume of the accommodation area, increase an area of the circuit board, increase types and a quantity of components, and improve function diversity of the optical module.

The present disclosure relates to an integrated busbar, a battery module and a battery pack, and belongs to the technical field of battery design. The integrated busbar comprises a bracket, a plurality of circuit boards, a plurality of pads and a plurality of connecting bars. The bracket has a plurality of battery mounting areas, each of which is used to provide a mounting space for one battery, and each battery mounting area has a first void hole. Each circuit board is connected to the bracket and part of the plurality of pads, and each circuit board has a second void hole arranged opposite to the first void hole. The plurality of connecting bars are used to connect a plurality of batteries assembled to the plurality of battery mounting areas, and each connecting bar is connected to at least one pad. By using the present disclosure, it is ensured that the integrated busbar can collect the state information of all batteries, thereby improving the comprehensiveness of the collected data and further improving the accuracy of the collected battery state information.
