The connection assembly for a battery module has a housing body, a cover plate and an openable and closable door, wherein the housing body is used for supporting a plurality of components; the cover plate covers the housing body and used for covering the plurality of components on the housing body; the cover plate is provided with a second through-hole, and the second through-hole positionally corresponds to at least one of the plurality of components; the openable and closable door is movably mounted on the cover plate, and is positionally changeable between an open position and a closed position; wherein in the open position, the openable and closable door opens the second through-hole to expose the at least one of the plurality of components; and in the closed position, the openable and closable door shields at least part of the second through-hole to cover the at least one of the plurality of components on the body.

Abstract: An identification and an application of an ALV-J MHC-B2 restrictive epitope peptide are provided, which belong to the field of genetic engineering. An amino acid sequence of the provided ALV-J MHC-B2 restrictive epitope peptide is selected from SEQ ID NO:1, SEQ ID NO:2 and SEQ ID NO:3. An application of the ALV-J MHC-B2 restrictive epitope peptide in preparing an ALV epitope-based vaccine is provided. Restrictive motif of B2-haplotype chicken MHC class I molecule binding peptides is identified by in vitro elution assay. Potential epitopes in four proteins expressed by ALV-J are systematically screened by motif. The immunogenic B2-haplotype chicken ALV-J T-cell epitope peptides are identified by functional validation. It provides a material and theoretical basis for the research and development of ALV epitope-based vaccines.
