Problems solved by technology

However, in this case, since the above-mentioned fixed contact piece portion and the contact terminal are electrically connected only by crimping force, it is difficult to maintain the electrical connection between the two in a stable state.
[0008] In particular, when the printed circuit board is assembled or after assembly, since the position of the printed circuit board is shifted relative to the case, the stability of the above-mentioned electrical connection is reduced, and the performance quality of the AC adapter may be reduced.

Abstract

The AC adaptor in the invention can cause the printed circuit board assembling work easier, improve productivity, and always ensure the connection stability of the fixing contact sheet part on one side of the casing and the contact terminal on one side of the printed circuit board. the printed circuit board (11) is assembled in a casing (13) with a connecting plug (14, 14), while in electric connection with a contact terminal (12, 12) disposed on the printed circuit board (11) and a fixing contact sheet part (15, 15) formed at the root side of the connecting plug (14, 14). The contact terminal (12, 12) is made of spring material so as to contact the fixing contact sheet part (15, 15) by compression joint. And, a depth direction limiting protrusion (17, 17, 17A) for limiting the position of the printed circuit board (11) in the casing (13) depth direction and a width direction limiting protrusion (16,16) for limiting the position of the printed circuit board (11) in the casing (13) width direction are disposed on side of the casing (13).

Description

technical field [0001] The present invention relates to an AC adapter and an assembly method thereof, in particular to an AC adapter in which a printed circuit board is installed in a shell with a plug and an assembly method thereof. Background technique [0002] A conventional AC adapter of this type is composed of a housing provided with a pair of plugs, and a printed circuit board housed in the housing. Figure 9 A conventional example of this AC adapter is shown. In this figure, reference numeral 1 denotes a housing made of synthetic resin, and a pair of plugs (not shown) are integrally fixed and molded in the housing 1 . [0003] The base side portion of the plug protrudes slightly toward the inner side of the housing 1, and fixed contact pieces 2, 2 are provided on the protruding portion. In addition, a printed circuit board 3 having an electronic component mounting surface and a wiring pattern surface is housed in the housing 1 . Contact terminals 4, 4 are provided ...
