JP2009277633A - Socket of plug connector for indoor wiring hardly causing tracking phenomenon - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem, wherein dust is accumulated on a gap which may be slightly generated between a socket and a plug of a plug connector for indoor wiring and catching of fire caused by leak current triggered by the reduction in the insulating resistance, when dust becomes wet may occur, and the so-called "tracking phenomenon" is generated. <P>SOLUTION: The tracking phenomenon is less apt to generate, since there is no accumulation of such dust in the gap between the plug and the socket, by arranging of insertion holes 3, (4) of the socket of the plug connector for indoor wiring. The insertion hole 3 projects from the socket, and the insertion hole 4 is arranged inside the socket. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

In the present invention, the insertion port of the insertion plug receiver is disposed obliquely downward with respect to the surface of the main body so that dust does not accumulate in the gap between the insertion plug and the plug reception.

The conventional insertion plug receiver is arranged with the insertion port slightly recessed from the surface of the main body, and it is difficult for dust to accumulate at the insertion port of the plug reception.

The area around the insertion slot of the plug receptacle is slightly recessed to make it difficult for dust to adhere to the insertion slot of the plug receptacle, but the depth is only about 0.5 mm. If there is even a slight gap, dust will accumulate, which will damp and cause insulation to deteriorate and cause a tracking phenomenon.

Means for Solving the Invention

The insertion port of the insertion plug is disposed obliquely downward with respect to the main body surface.

The invention's effect

Even if a gap is formed between the plug receptacle and the plug, dust does not accumulate, and it is possible to prevent a tracking phenomenon that occurs due to moisture.
Dust does not adhere to the insertion surface of the insertion plug as well as the insertion plug receptacle.
In addition, when the plug is inserted, the angle at which the cord bends becomes an obtuse angle, the degree of bending stress applied to the bending point is reduced, and the distance at which the cord protrudes from the insertion surface is shortened.

Embodiments of the present invention will be described below.
(A) The insertion ports 3 and 4 of the resin mold main body front part 1 are arranged obliquely downward with respect to the main body front part vertical surface.
(B) A notch 8 of a part composed of the contact 6 and the connecting conductor 7 corresponding to the angle of the insertion ports 3 and 4 is fitted to the protrusion 9 provided on the rear part 2 of the resin mold body. It is attached to the rear part 2 of the resin mold. In addition, the connection conductor 7 is provided with a wiring insertion terminal, and a wiring insertion port corresponding to the wiring insertion terminal is provided at the rear of the main body.
(C) The resin molded main body front part 1 is fixed to the resin molded main body rear part 2 to which the contactor 6 and the connection conductor 7 are attached by the mounting bracket 5.
