Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical outlet having a luminescent indicator.

This type of outlet has outlets on both sides, a plug blade on the back, and a light-emitting display section on the front, and the plug blade is inserted into an outlet installed on a wall, etc.
Display is performed by lighting up the light source of the light emitting display section. The display section is formed from a light source and a translucent cover provided opposite to the light source.
The cover attachment means includes a recess formed on the front surface of the main body, an engagement hole formed in the recess, and a claw protruding from the lower surface of the cover that engages with the engagement hole. Then, the cover is attached to the main body by fitting the cover into the recess and engaging the claw with the engagement hole. However, since the blade receptacle is provided inside the main body, it is difficult to provide the necessary number of claws on the transparent cover while avoiding the blade receptacle within the limited size. There was a problem that the cover could not be installed completely because it had to be held up by the individual nails.

The present invention has been made in view of the above circumstances, and relates to an electrical outlet that is not affected by the blade holder and is equipped with a light-emitting display section that allows a translucent cover to be reliably attached.

The details of the present invention will be explained below with reference to the drawings.
Reference numeral 1 denotes a main body, which has insertion holes 2 on both sides, receiving blades 3 on the inside facing the insertion holes, a rear plug blade 4 protruding, and a first recess 5 on the front surface.
has been established. The recess 5 is formed such that one end is located opposite the insertion hole 2, the other end is located outside the insertion hole 2, and is surrounded by projecting walls 6 and 7. In addition, 8 is a translucent cover, and the above-mentioned first
It fits into the recess 5 of. A light source 9 is provided inside the translucent cover 8, facing the cover 8, and is connected to the stopper blade 4. Then, second recesses 10 are formed inside the protrusion wall 6 on both sides near one end opposite to the insertion hole 2 of the first recess 5, and engagement holes 11 are formed on both sides of the other end of the recess 10. is forming. On the other hand, the cover 8 has engagement protrusions 12 that protrude laterally on both sides of one end and engages with the second recess 10, and engagement claws 13 that engage with the engagement holes 11 on the lower surfaces of both sides of the other end. Each is formed protrudingly. To describe the embodiment of the present invention in more detail, the main body 1
It is composed of a container body 15 and a lid body 16, and the insertion hole 2 is formed not only on both side surfaces but also on the bottom surface of the container body 15 and lid body 16. And vessel 15
There are provided three sets of receiving blades 3 integrally formed opposite the insertion hole 2. On the other hand, the lid body 16 is provided with a push button adjacent to the translucent cover 8, and one side of this button constitutes the projecting wall 7. Lid body 16
A through hole 18 is formed in the first recess 5 to allow the light source 9 to protrude from the back surface of the lid body 16 to the outer surface, and a recess 19 is further provided to accommodate the light source 9. A window hole 17b for protrusion is provided. Note that the through hole 18 may be formed larger than the light source, and the light source 9 may be positioned on the back side of the first lid 16 while facing the translucent cover 8. A switch 20 is inserted between the light source 9 and the plug blade 4 and is operated by a push button 17 to control the light source 9 to blink. This switch includes a ratchet gear 21 driven by a protrusion 17a protruding from the back surface of the push button 17, a movable contact piece 22 and a fixed contact 2 that are opened and closed by this gear.
It is composed of 3.

Next, the operation of the present invention will be explained. To attach the translucent cover 8 to the first recess 5 of the main body 1, press the engaging claw 13 on the lower surface of the cover 8 while inserting it into the engaging hole 11 of the first recess 5. is engaged with the engagement hole 11, and the engagement protrusion 12 of the cover 8 is engaged with the second recess 10 provided in the projecting wall 6, thereby completing the installation. Insertion hole 2 of translucent cover 8
Since the engaging protrusion 12 protruding to the side is provided instead of the downward engaging claw 13 at the position facing the opposite end, the two engaging claws 13 provided on the lower surfaces of both sides on the other end side and Due to the cooperative action, the translucent cover 8 can be reliably provided in the first recess 5 of the main body 1. Therefore, the provision of the push button 17 is even more effective in cases where the blade receiver 3 is in a tight position. Of course, in the case where the push button 17 is not provided, there are fewer restrictions imposed by the blade receiver 3, so the degree of freedom in design can be increased. Note that the switch 20 does not necessarily need to be provided, and the light source 9 may be turned on to indicate energization.

As described in detail above, the present invention has a plug blade protruding from both sides, an insertion hole on both sides, and a receiving blade inside facing the insertion hole, and the first recess of the main body. A second recess is formed inside the projecting wall on both sides near one end facing the insertion hole, and an engagement hole is formed on both sides of the other end of the first recess, and the translucent cover includes: Engagement protrusions that engage with the second recess are protruded laterally on both sides of one end, and engagement claws that engage with the engagement holes are formed on the lower surface of both sides of the other end. Even if only two claws are provided, the second recess provided in the main body 1 and the engagement protrusion provided in the translucent cover that engages with the second recess provided in the main body 1 can be This action allows the cover to be reliably attached to the main body.
