Abstract: A horizontal assembly method for permanent magnet motor is mainly to firstly dispose the first bracket and the second bracket on the motor assembly platform, then fix the stator assembly on the sliding carrier so as to move with the sliding carrier to sleeve over the fixed thimble to engage the first bracket, then position the rotor assembly between the fixed thimble and the movable thimble so as to fix the rotor assembly by the protruding movable thimble, then control the sliding carrier to assemble the stator assembly and the first bracket to the rotor assembly so that the one end of the rotational shaft can be supported by the first bracket, and finally assemble the second bracket to the stator assembly so as to support another end of the rotational shaft. Thereupon, the permanent magnet motor can be produced.

Abstract: An electrical connector assembly includes: a circuit board, provided with at least one chip; an electrical connector, electrically connected to one end of the circuit board, and used to be mated with a mating connector; and a metal shell, covering the circuit board and the electrical connector. The metal shell is provided with at least one through hole running therethrough. Each through hole is provided with a waterproof layer preventing liquid from passing from an exterior of the metal shell to an interior of the metal shell and enabling gas to pass between the interior and the exterior of the metal shell, thereby achieving water proofing and heat dissipation, avoiding malfunctioning of the electrical connector and the chip due to excess temperature or liquid entry, ensuring the reliability of signal transmission between the electrical connector and the chip, and prolonging the service lives of the electrical connector and the chip.

The heat dissipation members are provided on one or more sides of the shielding shell, and simultaneously abut the shielding shell and the circuit board, so that the heat generated in the operation of the electrical connector is transferred to the heat dissipation members via the shielding shell, and the heat is further transferred to the outside and the circuit board by the heat dissipation members, thus improving the heat dissipation efficiency of the electrical connector, and ensuring the stable operation of the electrical connector.

Abstract: An electrical connector assembly includes: a circuit board; a connector, located in front of the circuit board and electrically connected to the circuit board; a chip, provided on the circuit board, and electrically connected to the circuit board; a metal shell, covering the connector and the circuit board; and an inner film, made of a high heat conductive material, and wrapping the chip and the circuit board. At least a part of the inner film is located between the metal shell and the circuit board. When the chip generates a great amount of heat, the inner film, serving as a medium, can absorb the heat rapidly and conduct the heat to the metal shell so as to dissipate the heat outside.

Abstract: An electrical connecting apparatus, disclosed for a LED module, comprises a circuit board and an electrical connector disposed on the circuit board. The electrical connector comprises at least one insulator for accommodating the LED module, at least one heat-conducting device for conducting thermal energy generated by the LED module, and at least two terminals respectively contacting the LED module and the circuit board. The electrical connector can connect the LED module and the circuit board. However, only the LED module has to be replaced when it is broken. The LED can be replaced easily and the cost can be reduced. Furthermore, the LED module will not emit light onto the heat-conducting device disposed on the electrical connector. Moreover, the thermal energy generated by the LED module can be quickly conducted to the circuit board by the heat-conducting device and then be dissipated by heat sinks of a heat-dissipating module.
