JPS604393Y2 - exposed outlet - Google Patents

Description

[Detailed explanation of the idea] This invention relates to electrical outlets that are used in an exposed manner.

Conventionally, this type of outlet has a blade holder spring that is screwed onto the container body or is simply press-fitted and fixed, and if the insertion hole of the plug blade in the lid body and the blade holder spring are misaligned when assembled. If the plug blade is inserted obliquely or the plug blade is inserted diagonally, it may be difficult to connect the plug blade.

This idea was created by focusing on the above circumstances,
The purpose is to provide an exposed outlet in which the blade holder spring moves within a permissible range and can be easily connected even if the insertion hole and the blade holder spring are misaligned or if the plug blade is inserted obliquely.

An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

Reference numeral 1 designates a blade receiving spring, which has a tongue piece 4 protruding from one side of a base 3 forming a pair of contact pieces 2, 2, and a leg piece 6 which protrudes downward from the other side and has a notch 5 at its tip; A terminal portion 8 of the winding screw 7 is formed.

Reference numeral 9 denotes a container body, which forms a recess 10 into which the tongue piece 4 is loosely fitted, and a hole 11 through which the leg piece 6 is inserted downward and penetrates to the back surface.

12 is a screw hole for fixing to construction material (not shown), and 13 is a wire hole.

Reference numeral 14 denotes a lid body, which has an insertion hole 15 for a plug blade (not shown) on the front surface, and forms a container 16 in which the blade receiving spring 1 is housed in combination with the container body 9.

Then, loosely fit the tongue piece 4 into the recess 1-0, and insert the leg piece 6 into the hole 1-0.
The blade receiving spring 1 is fixed to the container body 9 by inserting it into the container body 9 and expanding the notch 5.

In this state, the tongue piece 4 has a gap between it and the recess 10, and is movable in the direction N using the leg piece 6 as a fulcrum.

Note that the leg piece 6 may be press-fitted into the hole 11 or may be supported pivotably.

Therefore, if the insertion hole 15 of the plug blade and the blade receiving spring 1 are assembled out of alignment, or if the plug blade is inserted diagonally,
The blade receiving spring 1 moves within the allowable range of the gap, and connection can be made without increasing the insertion force.

As explained above, this device includes a blade receiving spring 1 which forms a pair of contact pieces 2.2, has a tongue piece 4 protruding from one side, and has a leg piece 6 and a terminal part 8 formed on the other side, and a blade support spring 1 which has a pair of contact pieces 2.2 and a tongue piece 4 that is loosely formed. A hole 11 forming a fitting recess 10 and into which the leg piece 6 is inserted downward.
Since the outlet is made up of a container body 9 with a plug blade formed thereon and a lid body 14 which has an insertion hole 15 for a plug blade on the front side and forms a container 16 that, in combination with the container body 9, houses a blade holder spring 1, The receiving spring 1 moves within the allowable range of the gap, and even if the insertion hole 15 and the blade receiving spring 1 are misaligned or the plug blade is inserted diagonally, the connection can be easily made.

In particular, this effect is even more pronounced in the hook-type or multi-pole outlet shown in FIG.
