11. The charging-stand lead frame assembly of claim 10, wherein:
the raised rib has a top surface in thermal contact with the bottom surface of the temperature sensor and a pair of side surfaces in thermal contact with the side surfaces of the first input terminals of the two first leads.
12. The charging-stand lead frame assembly of claim 10, wherein:
the protruding rib has a tapered leading end for guiding the protruding rib to be inserted between the two first leads and the temperature sensor.
13. The charging-stand lead frame assembly of claim 7, wherein:
the frame body has an open accommodation space in which the first input ends of the two first leads and the temperature sensor are located.
14. The charging-stand lead frame assembly of claim 1, wherein:
the temperature sensor is a surface mount type NTC sensor or a surface mount type PTC sensor, and the temperature sensor is welded on the two first leads in a surface mount mode.
15. A charging stand, comprising:
a housing;
the charging-dock lead frame assembly of any one of claims 1-14, mounted in the housing; and
a charging terminal disposed in the case and passing through the frame body.
