The application discloses an L-wave standing wave deflection cavity for low-energy electron beam bunch length measurement and relates to the technical field of electron beam bunch measurement. The application discloses an L-wave standing wave deflection cavity for low-energy electron beam bunch length measurement and relates to the technical field of electron beam bunch measurement. The cavity chain comprises end cavity one, intermediate cavity and end cavity two, the waveguide is arranged on the intermediate cavity through the transition plate, arc-shaped matching grooves are symmetrically arranged at both ends of the transition plate along the axial direction close to one side of the intermediate cavity, the arc-shaped matching grooves are matched with the outer shaft surface of the end cavity one or the end cavity two at the corresponding end, and the slot processing of the end cavity one and the end cavity two is reduced. On one hand, the slotting workload during installation of the deflection cavity is reduced, and the machining efficiency is improved; on the other hand, the combined surface of the waveguide coupler is more fitted, and the brazing is facilitated.

The utility model provides an electrode terminal, a battery cover plate assembly, a battery and electric equipment. The electrode terminal comprises a pole column, a first electrode and a second electrode, the cap cover and the pole column are different metal pieces, and at least one part of the cap cover and one end of the pole column in the axial direction are mutually connected into a whole. The electrode terminal comprises the pole and the cap, and the pole and the cap are directly connected into a whole, so that the use amount of welding flux is reduced, and the cost is saved.

The invention provides a liquid accumulator, a machining method of the liquid accumulator and a compressor. The liquid storage device comprises a barrel which is an integrated piece formed through spinning, an air inlet hole is formed in the first end of the barrel, and the second end of the barrel is of a closed structure. At least one exhaust hole is formed in the side wall of the barrel; and the air suction pipe is connected to the exhaust hole in a sealing manner and is communicated with the cylinder body. According to the invention, the integrated cylinder body is formed through spinning, the first end of the cylinder body forms the air inlet hole, and the second end of the cylinder body is of a closed structure, so that an end cover in an original three-section type liquid accumulator is canceled, parts during assembly of the liquid accumulator and welding flux during welding of the parts are saved, the assembly efficiency of the liquid accumulator is improved, and the cost of the liquid accumulator is reduced.
