The invention discloses a quick dismounting and filling-sealing apparatus for an electric connector. The apparatus comprises an aluminum machined part A (1) and an aluminum machined part B (2), and further comprises a butterfly bolt (3) and a butterfly nut (4). According to the apparatus, a filling-sealing process is simple in operation; use is reliable; the problem of an assembling clearance caused by a through hole in one side originally is solved; different sets of components can be inserted and mounted at will and are high in butting precision; compared with screw connection, relatively good interchangeability is achieved; an unfavorable factor of tedious dismounting is avoided on the premise of the same fastening effect; the service life of the apparatus is prolonged; and especially a practicality conception of the apparatus greatly improves filling-sealing efficiency of the electric connector.

The invention belongs to the field of device packaging and heat dissipation, and relates to a microchannel aluminum heat pipe pre-extruded narrow seam spherical friction stir welding filling packaging process, which mainly includes: 1) extracting the internal environment of the micro heat pipe that has been sealed on one side to a high temperature Vacuum state; 2) Pour a certain amount of working fluid into the micro heat pipe; 3) Extrude and seal the micro heat pipe by using the extrusion sealing device; 4) Use the spherical friction stir welding process to weld and seal the micro heat pipe, and the welding direction is along the extrusion sealing line 1 / 2 position; 5) Use the cutting device to cut along the weld seam direction at the 1 / 2 position of the weld seam, and the perfusion and packaging process of the micro heat pipe unit is completed; 6) Remove the vacuum device and the perfusion device. The invention only needs 5 processes to complete the production of the microchannel aluminum heat pipe unit, greatly shortens the intermediate sealing and blanking section, simplifies the processing and manufacturing process, has high material utilization rate, good packaging effect, high reliability, low scrap rate, and low production cost. The efficiency is high, and the service life of the spherical stirring head is long, and the production process is green and environmentally friendly.

The invention belongs to the field of device packaging and heat dissipation, and relates to a high-efficiency needle-free friction stir welding pouring packaging process for porous microchannel aluminum heat pipes, including: using a vacuum device to vacuumize the inside of the microchannel aluminum heat pipes that have been sealed on one side; The working fluid is poured into the microchannel aluminum heat pipe through the perfusion device; the microchannel aluminum heat pipe is welded and sealed by the needle-free friction stir welding process; the cutting device is used to cut along the direction of the weld at the 1 / 2 position of the weld, and the microchannel aluminum The heat pipe unit perfusion encapsulation process ends. The present invention only needs 4 processes including one clamping-vacuumizing-perfusion and one needle-free friction stir welding sealing to realize the perfusion and packaging manufacturing of the micro-channel aluminum heat pipe unit, which greatly shortens the processing and manufacturing process, and has high reliability and low scrap rate Low cost, high production efficiency, high material utilization rate, low performance requirements for packaging equipment, long service life of needle-free stirring head, and green production process.

The invention relates to rectangular electric connector encapsulationpotting equipment and encapsulationa potting method, and the encapsulationpotting equipment comprises a encapsulationpotting mainboard which is provided with a plurality of encapsulationpotting grooves for encapsulatingpotting a plurality of rectangular electric connectors, and wherein the encapsulationpotting grooves are through grooves; the a wire lapping rod which is fixed on the encapsulating main board and is used for carding connecting wires encapsulated by the rectangular electric connector; the and a pocket plate which is used for locking the rectangular electric connector before potting encapsulation and supporting the rectangular electric connector after encapsulationpotting, and wherein the pocket plate can befixedly connected with the encapsulationpotting main board through a plurality of threaded fasteners.; when When the rectangular electric connector is installed, one end of the rectangular electric connector is inserted into one encapsulationpotting groove, and the pocket plate is fastened at the other end of the rectangular electric connector. According to the invention, a plurality of rectangular electric connectors can be encapsulated at the same time, the encapsulation process is effectively simplified, and the encapsulation efficiency is improved.

The invention discloses a method for manufacturing a rotor of a permanent magnet motor, comprising: coating a first high-temperature-resistant silicone grease layer on the first surface of a polyimide film, and pasting the second surface of the polyimide film on the first surface of the polyimide film. The surface of a pressing plate forms the first component, or directly coats the surface of the first pressing plate with Teflon coating to form the first component; the first component and the rotor stamping are sequentially placed on the shaft, and then the first component and the rotor stamping Compress the rotor punches to form a rotor core, and then lock the rotor core and the first component; assemble the permanent magnet in the rotor core to obtain a semi-finished product, and then fill the gap between the permanent magnet and the rotor punch with glue. The sealant is cured to obtain a workpiece; a second pressing plate is installed on the obtained workpiece, and the workpiece and the second pressing plate are locked to obtain a permanent magnet motor rotor. The method has a simple technological process, is easy to realize, and has low cost, and can effectively prevent the loss of potting glue while ensuring high reliability of the rotor.
