Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a power supply connection device with an extension cord used for supplying power from a power source to electrical equipment.

[Background of the invention]

Looking at the types of electrical product plugs and power plugs internationally, the plug pins are flat, and the plug receptacle (i.e., the plug socket also has a slotted hole with a rectangular cross section). There are two types of plugs: those with a round rod-shaped insertion pin and those with a circular hole in the plug holder.In the latter case, there are two types of distances, or spans, between the round rod-shaped insertion pins.

Therefore, if you travel to a country with different standards, you may be inconvenienced by not being able to use the electrical appliances you brought with you because the plugs and plug receivers do not match. Additionally, there is the inconvenience that foreign-made electrical products brought back from abroad cannot be used as they are in Japan.

[Summary of the invention]

In view of the above points, an object of the present invention is to provide a power supply connection device that can easily and universally connect different types of plugs and plug receptacles.

According to the present invention, a pair of flat pins protrudes from one end;
It has a built-in pair of fingers that can make an electrical connection even if either a flat pin or a round bar pin is inserted from the other end.
each of the pins and fingers being electrically connected and held in a pair of halves of an insulator;
A plug/plug receptacle integrated connector with a pair of flat pins protruding from one end and a round bar-shaped pin protruding from the other end, each of which is electrically connected and inserted into a pair of halves of the insulator. Plug 2/Plug 2 held together = Connector and a pair of round bar pins protrude from one end and are held in a pair of insulators 7 and -7, and these pins are connected to the cord. A plug configured to be connected to the plug, a cord having one end electrically connected to the plug, and a pair of fingers that can make an electrical connection regardless of whether a flat pin or a round bar pin is inserted. A plurality of plug receiving parts are built into an integral no.-7 of an insulator, and the plug receiving part is configured to be connectable to a cord and is electrically connected to the other end of the cord. - A power supply connection device comprising a plug receptacle is provided. [Embodiment] As shown in FIG.
It consists of a main body portion connected with a main body portion, and two adapters, that is, a plug/plug receiver integrated connector 10 and a plug/plug integrated connector 40.

As shown in FIG. 2A, the plug/plug receiver integrated connector (i.e., male and female connector) 10 has two halves 10^ made of an insulating material such as plastic, and is sandwiched between them (with flat pins 11 and fingers 12). A square groove 101 is provided at the upper end of the 8-710a, and a semicircular notch 102 with a square groove is provided at the lower edge of the half 10a.Connection Conductor 1
0b has a cut-out part 110, and this part
)jOa are fitted into the square holes formed by the square grooves 101 on the upper edges of each half, and the connecting conductor 10b is locked in the joined halves and will not fall off. Furthermore, -
Inside the half 10a, in order to hold the connecting body in place,
A rod-shaped projection 13 and a box-shaped projection 14 are provided. The two 8-710a sandwich the connecting conductor 10b between them so that the flat pin 11' projects upward and the lower ends of the fingers 12 are aligned with the half lower fiK, and the screw hole 10
They are fixed to each other with screws and nuts passed through 3. , the square grooved semicircular notch 102 forms an elliptical hole with square grooves when the halves are assembled. The square grooved oval hole and the fingers 12 will be explained in detail later.

The plug/plug integrated connector (female and male connector) 40 is
As shown in FIG. 2B, a connecting conductor 4 is formed by integrating two halves 40a, a flat pin 41, and a round bar pin.
It consists of 0b. Notch 41G of connection conductor 40b
and groove 420 engage with half square grooves 411 and 421, respectively, and connection conductor 40b is held in a predetermined position. Reference numerals 43 and 44 are projections provided within the half to hold the connecting conductor 40b in a predetermined position. Further, 45 is a screw hole for fixing the half.

As shown in Fig. 2C, the extension cord plug 20 has two halves of 20 m, one end of which can electrically connect and fix the cord 22 with a screw 201, and the other end of which is a pin shaped like a round bar. It consists of 21. Groove 2 of pin 21
3 fits into the square groove 26 on the upper edge of the half, and also works together with the protrusion 25 provided on the half, so that the pin 21 connects the two halves 2.
It is kept within 0a. Further, 202 is a semicircular hole for passing the cord 22 through, and 24 is a hole for a screw for fixing the halves to each other.

The multi-plug receptacle 30 of the extension cord consists of two halves 30& and a connecting conductor 30b which can electrically connect and fix the cord 22 by means of a screw 32, as shown in FIG. 2D. Each connection conductor 30b has five fingers 31
An oval hole 302 with square grooves is provided in the half 30 & of the portion corresponding to the insertion opening of these fingers. 3
01 is a circular notch for passing the ninth hole through which the cord 22 is passed, and 33 and 34 are round rod-like projections and plate-like projections for holding the connecting conductor in a predetermined position.

Further, 351 is a hole for a half fixing screw, and the other 35 is a guide pipe with the same screw.

The connecting conductor 30b is folded back at a portion 311, and a shape material in which the portion 311 is expanded by 180° is made from a flat metal plate.

Therefore, the finger 31 is made up of two opposing spring pieces, and forms a cylindrical passage (the cross section of which is approximately elliptical) that receives a round bar-shaped pin and makes electrical contact with it.
An insertion passage for the flat pin is formed in the gap between the two spring pieces. The basic structure of the fingers is the same as that of the fingers 12 of the male and female connector 10 shown in FIG. 2A, and the fingers 12 consist of two spring pieces and can accept both round bar-shaped pins and flat plate-shaped pins.

As is clear from FIG. 2D, the hole 302 arranged corresponding to the pin diameter of the finger has a square groove on its outer periphery for passing the flat pin, and has an elliptical corner as a whole. This is also the same for the male and female connectors 10 shown in the wJzA diagram, and when the half 10 m are combined, the semicircular notch 102 with the square groove is the second D.
It has the same shape as the square grooved oval hole 302 shown in the figure.

The plug receiving portion according to the present invention can be used both for a plug with a round bar pin having a small diameter and a narrow span, and for a plug having a round bar pin having a large diameter and a wide span. That is, in the case of a plug with a small diameter and span, the pins and fingers will contact each other on the inside, as shown in FIG. 3A. Conversely, in the case of a plug with a large diameter and span, the pins and fingers will contact on the outside, as shown in Figure 3B. Furthermore, the plug receiving part according to the present invention includes:
