The ring main unit comprises a gas tank, the gas tank comprises a first functional unit, a second functional unit, three-phase buses and an insulating supporting piece, the two ends of each phase of bus are connected with the first functional unit and the second functional unit respectively, and a first installation part is arranged in the middle of the insulating supporting piece in the arrangement direction of the three-phase buses at the corresponding positions. Second mounting parts are arranged at the two ends respectively, the first mounting parts are matched and connected with the bus located in the middle, and the second mounting parts are matched and connected with the buses located at the ends. According to the gas tank and the ring main unit, when short-time withstand current and peak withstand current exist in the gas tank and the ring main unit, the bus is not easy to deform or ablate, and the gas tank and the ring main unit are simple in structure and convenient for spatial arrangement.

The utility model relates to the field of semiconductor testing, and particularly discloses an adapter plate and equipment suitable for chip CP testing. The adapter plate comprises a plate body, one side of the plate body is a gas distribution face, the other side of the plate body is an adsorption face, and the gas distribution face and the adsorption face are both planes. A gas distribution groove is formed in the gas distribution surface, adsorption holes are distributed in the bottom of the gas distribution groove, and the adsorption holes penetrate through the plate body and are communicated with the adsorption surface. The chip is clamped and transferred by the adapter plate in a direct negative pressure adsorption mode, so that the operation efficiency and the detection precision are effectively improved.

The invention relates to a stable and reliable food processor which comprises a permanent magnet direct current brushless motor, the motor comprises a stator and a rotor, the rotor comprises a rotor iron core and a permanent magnet, the inner side of the outer edge of the rotor iron core is provided with an installation groove for the permanent magnet to be inserted, and the position, opposite to the permanent magnet, of the outer edge of the rotor iron core is provided with a rotor salient pole protruding outwards. A groove is formed between every two adjacent rotor salient poles, the rotor further comprises a fixing cage which is arranged outside the rotor iron core and integrally formed, the fixing cage comprises end plates located at the two ends of the rotor iron core and fixing columns located on the outer side wall of the rotor iron core and connected with the end plates at the two ends, the fixing columns are located at the grooves, and the outer diameter of the fixing columns is not larger than that of the rotor salient poles. The fixing cage is provided with the fixing columns at the grooves to integrally wrap the rotor, the strength of the fixing cage is increased, the rotor iron core and the permanent magnets are fixed and limited, and the situation that the strength of the fixing cage is affected due to the fact that the periphery bears large centrifugal force when the fixing cage is fixedly connected only through the connecting column in the center and deforms is avoided.
