The present invention relates to a locking mechanism of a miniature electric connector. The locking mechanism comprises a necking sleeve and a locking screw, wherein the necking sleeve is in a step structure and comprises a conical thin wall part and a round thick wall part; the middle part of the locking screw is provided with a circular groove; the necking sleeve is arranged outside the locking screw, and the conical thin wall part is mounted in the circular groove of the locking screw and meanwhile in a step fixed hole corresponding to an outer shell of the electric connector; and the abutting part of the locking screw, which is exposed out of the outer shell of the electric connector, is a full thread. The locking mechanism of the miniature electric connector occupies small space, can obtain a smaller center distance of the electric connector, be beneficial to the miniaturized development and realize the seamless attachment of a plug and a socket outer shell after being spliced.

The invention belongs to a honeycomb preparation technique, and relates to a preparation method of honeycomb core materials for seamless splicing. According to the method, nonmetal honeycombs, which are same in material and size, are selected to be spliced, and edge cutting treatment is conducted on spliced edges of the honeycombs; then, notch pre-treatment is conducted on the honeycombs to be spliced along splicing lines separately to make the inner walls, at the spliced edges, of the honeycombs remain in an open state, and the inner sides of the spliced edges of the honeycomb notches are coated with node glue; the openings at the two ends of each spliced edge are embedded and spliced, the notches coated with the node glue at the two ends are bonded with each other to form an integral honeycomb grid at a spliced place, and the spliced edges are fixedly pasted by metal wires; finally, the honeycombs after splicing are put into an oasthouse for heating treatment, after solidification iscompleted, the honeycombs are cooled to the room temperature, the metal wires are removed, and seamless solidification of the spliced edges of the notches coated with the glue is finished. Through utilization of grid features of the honeycomb core materials, the spliced notches are designed, and under the cooperation of a fixing effect of the metal wires, seamless bonding and splicing of the honeycomb core materials are completed; the integral continuity of the spliced honeycombs is maintained to the maximum degree.

The present application discloses a packaging structure and a packaging device. The packaging structure includes: a base layer, one side of the base layer is used to form a part to be packaged; a first packaging layer is formed on a side of the part to be packaged facing away from the base layer, And cover the side wall of the component to be packaged; the first buffer layer is arranged around the periphery of the first packaging layer and pasted on the side wall of the first packaging layer; the second packaging layer is formed on a side of the first packaging layer facing away from the base layer side, and cover the sidewall of the first buffer layer. Through the above method, the present application can enhance the bonding force between the film layers, reduce the possibility of the film layer falling off and enhance the ability of the packaging device to block water and oxygen, so as to realize the seamless bonding between the film layers.

The invention provides an air-conditioner indoor unit which comprises a case and a first air guide plate. One end of the first air guide plate is installed on the case in a rotating mode and can open or close an air outlet of the case. The case is provided with a first protruding portion. The rotating connection end of the first air guide plate is provided with a second protruding portion. When the first air guide plate closes the air outlet, the first protruding portion makes contact with the second protruding portion. According to the air-conditioner indoor unit, the case is provided with the first protruding portion, the rotating connection end of the first air guide plate is provided with the second protruding portion, when the first air guide plate closes the air outlet, the first protruding portion makes contact with the second protruding portion, and therefore the first air guide plate and the case can be matched in a seamless mode, and the problems that due to the fact that a gap is reserved between the air guide plate and the case, the appearance of the air-conditioner indoor unit is poor in attractiveness and dust enters the case from the gap and causes pollution in the prior art can be solved.

The present application relates to an evaporation device, which includes a crucible body, a side heating device arranged around the crucible body and a bottom heating device arranged below the crucible body; the bottom heating device can be move up and down along the height direction of the side heating device, and support the crucible main body to rise to a position higher than the side heating device. In this application, a heating device is provided at the bottom, so that the main body of the crucible can move up and down, thereby improving maintenance efficiency, shortening maintenance time, and reducing redundant working procedures.

Method of limiting low excitation, calculating measured impedance of generator terminal by detecting generator terminal voltage and terminal current, when the measured impedance entering low excitation limited impedance circle, the low excitation limits prolong action of 40-60 ms on amplifying excitation current to maintain generator in stable operation situation, the low excitation limited impedance impedance circle covers static stable loss of excitation protection impedance circle to implement seamless connection with generator loss of excitation protection impedance criterion, and preventthe generator in low excitation operation, the low excitation is limited lagging behind the loss of excitation protection action, thereby generator error jump is caused. The invention is used in generator excitation regulation, comparing with former low extitation limiting method, the invention is more visualized, the loss of excitation protection and low excitation are all R-X impedance plane coordinate description and easy to cooperate with each other.
