Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1: referring to accompanying drawing 1 to Fig. 3.
A kind of DC assembly, comprise DC 1 and a plurality of binding post 2, described DC 1 comprises central core needle 11, a plurality of insulating sleeve 13 and a plurality of metal sleeve 12, described insulating sleeve 13 and the staggered socket of metal sleeve 12, and innermost layer is insulating sleeve 13, outermost layer is metal sleeve 12, and the rearward end of the rearward end of insulating sleeve 13 and metal sleeve 12 all exposes; The middle part of central core needle 11 is socketed on the insulating sleeve 13 of innermost layer; Described binding post 2 comprises Access Division 21 and pin 22, and pin 22 is connected in the lower end of Access Division 21; The side of the rearward end of the side of the rearward end of metal sleeve 12 and central core needle 11 respectively with Access Division 21 clampings of a binding post 2.
The utility model adopts the mode of clamping that the metal of binding post 2 with DC 1 rear end partly is connected, and is simple in structure, and easy to operate when assembling, and reduces production costs; When being connected with circuit board, the interface that only pin 22 of each binding post 2 need to be inserted circuit board gets final product.
Further, the Access Division 21 of described binding post 2 is circular arc, and the diameter of this place, Access Division circular arc less than with the diameter of the rearward end of the metal sleeve 12 of these binding post 2 clampings, perhaps the diameter of this place, Access Division circular arc less than with the diameter of the rearward end of the central core needle 11 of these binding post 2 clampings.
