Abstract: A system includes a baseband component, an optical transceiver component, a first pluggable radio frequency component, and a wireless head-end component. The baseband component is configured to provide a radio frequency signal to the first pluggable radio frequency component through the optical transceiver component. The optical transceiver component is connected to the first pluggable radio frequency component through an optical fiber. The first pluggable radio frequency component is connected to the wireless head-end component in a plugging manner.

Abstract: The embodiment of the present application relates to the field of battery, and in particular relates to a battery, an electric apparatus, and a method for producing a battery. The battery of the present application includes: a battery cell; a box body configured for accommodating the battery cell and comprising a sleeve, and a first end cover and a second end cover for sealing both ends of the sleeve in a height direction respectively; a first insulating member, at least part of the first insulating member being located between the first end cover and the battery cell; and a second insulating member, at least part of the second insulating member being located between the second end cover and the battery cell; where an inner wall of the sleeve is provided with a fixing portion configured to fix the first insulating member and the second insulating member.

Abstract: A case, a battery, a power consuming device, and a method for assembling a case are provided. The case includes a first case body, an accommodating groove, a sealant, and a second case body. The first case body is provided with an opening. The accommodating groove is provided in a peripheral direction of the opening. The sealant is accommodated in the accommodating groove. The second case body is provided with a peripherally-arranged joint part. The joint part is configured to extend into the accommodating groove and be joined with the sealant when the second case body covers the opening, so as to form a sealed connection between the first case body and the second case body. The accommodating groove can limit the sealant, the sealant does not shift in the accommodating groove, and a sealing failure is less likely to occur, thus ensuring the sealing performance of the sealant.
