Problems solved by technology

[0005] In the erroneous connection prevention mechanism of the above-mentioned electric equipment, because the deflection amount of the concave portion formed on the terminal device and the deflection amount of the convex portion formed on the plug are not so large as to be visible, there is a gap formed on the plug. The problem that the normal fitting operation of the convex part to the concave part formed on the terminal device takes time
[0006] In addition, the combination of the terminal device and the plug is not a set, and there are cases where plugs with different performance and functions are connected to the terminal device, and there is a problem of mistakenly connecting a plug that does not properly correspond to the terminal device to the terminal device.

Embodiment

[0037] Next, examples of the present invention will be described, but the present invention is not limited to the examples at all unless the gist of the present invention is exceeded.

[0038] First, initially use Figure 1 ~ Figure 4 , the terminal device A constituting the erroneous connection prevention mechanism of the electric equipment of the present invention will be described.

[0039] The terminal device A is formed by joining vertical end surfaces 1" of two half-divided bodies 1' of the same shape constituted by a horizontal part 1a' and vertical parts 1b' erected at both ends of the horizontal part 1a'. Insulating shell 1.

[0040] An inverted trapezoidal fitting recess 1a2' is formed on the top plate 1a1' of the horizontal part 1a'. The fitting recess 1a2' is not formed in the center of the horizontal part 1a', but is biased toward one of the opposite vertical parts 1b'. The vertical portion 1b' side is configured in a manner. The half-divided body 1' is symmetr...

Abstract

The invention discloses an electrical apparatus provided with a wrong connection preventing mechanism, which is structured in a way that, on a vertical inner wall (1B1) of a housing vertical part of opposite housing vertical parts (1B) of a terminal device, a housing side wrong connection preventing component (N1) is installed, also, on one vertical side wall of opposite vertical side walls (P4) of a plug (P), a plug side wrong connection preventing component (N2) is installed, when the plug is tabled in a plug tabling concave portion (C1) in a mode that the housing side wrong connection preventing component and the plug side wrong connection preventing component are opposite, the housing side wrong connection preventing component and the plug side wrong connection preventing component are in a state of normal tabling. The electrical apparatus in the invention can practically prevent the circumstance that the plug is connected with the plug tabling concave portion of the terminal device in a state of wrong connection.

Description

technical field [0001] The present invention relates to an electric device for preventing incorrect connection of the electric device, which is composed of a terminal device and a plug connected to the terminal device. Background technique [0002] Patent Document 1 discloses, as an example, an electrical socket composed of a concave portion biased toward one side wall side opposite to a terminal device and a convex portion biased toward one side wall side formed on a plug. Misconnection prevention mechanism of equipment. [0003] [Prior Art Literature] [0004] [Patent Document 1] Japanese National Publication No. 2009-527072 [0005] In the erroneous connection prevention mechanism of the above-mentioned electric equipment, because the deflection amount of the concave portion formed on the terminal device and the deflection amount of the convex portion formed on the plug are not so large as to be visible, there is a gap formed on the plug. There is a problem that it tak...
