Since the (cover 3) is formed integrally with the plate body (plate portion 24), sufficient strength can be obtained at the portion between the screw insertion hole 33 and the recess 25, and the plate Since the main body is unnecessary, there is an advantage that the number of parts can be reduced.

Next, the blade receiving member 2 housed inside the body 1
The structures of 1, 2 and the terminal portion will be described.

In the third to sixth storage chambers 13 to 16 of the body 2, the flat blade insertion holes 27a of the insertion portions 26, 26 are inserted.
Also, the blade receiving member 21 that receives the flat blade and the round pin blade inserted into the round pin blade insertion opening 27b is stored. The blade receiving member 21 is a blade receiving spring 35 for a flat blade for receiving a flat blade.
And a blade receiving spring 36 for a round pin type blade for receiving a round pin type blade
Have and. Here, the third storage chamber 13 and the fifth storage chamber 1
5, and the blade receiving members 21 housed in the fourth housing chamber 14 and the sixth housing chamber 16 constitute terminal blocks A and B together with corresponding power supply terminal portions.

As shown in FIGS. 6 and 7, the terminal blocks A, B are provided with blade receiving springs 35, 35 for flat blades at both ends, and a terminal plate 37 constituting a power source terminal portion at a substantially central portion. , 37 provided with conductive members 38A, 38B,
It is composed of round pin type blade receiving springs 36, 36 for fixing to the both ends of the conductive members 38A, 38B. Conductive member 3
8A is formed by punching a conductive plate material into the shape shown in the development view of FIG. 9 and bending a predetermined portion. The conductive member 38B is also formed by punching into a shape similar to the developed view of FIG. 9 and bending a predetermined portion, although the shape of the details is different.

The blade receiving springs 35, 35 for flat blades each have a pair of spring pieces 35a, 35b facing each other flexibly, and one spring piece 35a has a width dimension shorter than that of the other spring piece 35b. Has been formed. In addition, the spring pieces 35a,
35b has a width that narrows as the distance between the two approaches the tip, and is bent so that the distance between the tips expands, and a flat blade is inserted from the tip between the spring pieces 35a, 35b. It's getting easier. The blade receiving spring 35 for one flat blade (the side housed in the third storage chamber 13) is connected to the rear edge of each spring piece 35a, 35b, while the other blade blade is flat. The blade receiving spring 35 (the side housed in the fifth storage chamber 15) is connected by a side edge on the rear end side of each spring piece 35a, 35b, and one end edge on the rear end side of the wide spring piece 35b. More substantially L-shaped fixing pieces 39, 39 are extended. A columnar protrusion 39a protruding rearward is provided at the tip of the fixing pieces 39, 39.

In the round pin type blade receiving springs 36, 36 for a blade, as shown in FIG. 8, a pair of spring pieces 36a, 36a are provided at both ends of a fixing piece 36b by bending a band-shaped conductive plate material. The distance between the pair of spring pieces 36a, 36a becomes narrower as they approach the tip, and the tip ends are bent so that the distance between them expands.
A round pin type blade is easily inserted between a and 36a. Then, a circular through hole 36c is formed in the center of the fixing piece 36b.
Through the through hole 36c and the conductive member 38
The protrusion 39a protruding from the fixing piece 39 of A, 38B is inserted, and the protrusion 39a is caulked to incline the blade receiving spring 36 for the round pin type blade to the blade receiving spring 35 for the flat blade. The state is fixed to the fixing piece 39. The round pin type blade receiving blade spring 36 is arranged rearward of the flat blade receiving blade spring 35, and the flat blade receiving blade receiving spring 3 is inserted from the flat blade inserting opening 27a.
The distance from the round pin type blade insertion opening 27b to the round pin type blade receiving spring 36 is longer than the distance up to 5, for the following reason.

That is, when the lengths of the flat blade and the round pin blade of the plug are compared, as shown in FIG. 10, the round pin blade 502 is relatively larger than the flat blade 500. Since the dimensions are often long, as shown in FIG. 11, the distance from the flat plug blade insertion port 27a to the flat plug blade blade receiving spring 35 and the round pin type blade insertion port 27b to the round pin blade blade Receiving spring 36
If the distance is equal, the position where the blade starts contacting with the blade receiving springs 35 and 36 becomes almost the same in any type of plug, and in the plug having the long blade 502, the charging portion (blade receiving springs 35 and 36) The amount of the blade 502 exposed to the outside of the blade insertion opening in the state of being in contact with the blade 502 increases, and the risk of an electric shock accident increases. Therefore, if the round pin type blade receiving blade spring 36 is arranged rearward of the flat blade blade receiving spring 35 as in this embodiment, as shown in FIG. Even if a plug having a long blade is connected by absorbing the blade at the position of the blade receiving springs 35, 36, the blade is not exposed to the outside of the blade insertion port in the state of being in contact with the charging part to prevent an electric shock accident. You can eliminate the danger. Further, this makes it possible to lower the height of the barrier for electric shock protection, that is, the height of the peripheral wall of the recess 25 (depth of the recess 25), and lower the peripheral wall of the recess 25 (depth of the recess 25). By making the height shallow, the height of the plate portion 24 can be reduced and the degree of freedom in design is increased.

Here, as shown in FIG. 13, a portion of the tip end of each spring piece 36a, 36a which constitutes the blade receiving spring 36 for the round pin type blade is in contact with the round pin type blade. If the curved surface shape corresponds to the outer shape of (3), the contact area between the round pin type blade receiving springs 36, 36 and the round pin type blade can be increased to stabilize the contact.

The power supply terminal portion includes a terminal plate 37 and a lock spring 4.
It has a quick-connect terminal structure composed of 0 and a release button 41, and is provided with a terminal for connecting an electric wire from a power source and a terminal for feed wiring for feeding and wiring to another outlet or the like.
Each terminal board 37 has a strip-shaped contact piece 37a that contacts an electric wire.
And a support piece 37b supporting the locking spring 40 are formed in a substantially U shape in plan view so as to face each other in substantially parallel to each other, and the contact pieces 37a, 37a are connected so as to face each other in substantially parallel. They are connected by a piece 37c. The terminal plates 37, 37 configured in this way are arranged such that the longitudinal direction of the contact piece 37a is aligned with the front-back direction of the body 1 (the wire insertion direction with respect to the wire insertion port 18).
0 and the release button 41 together with the first and second storage chambers 1
They are stored in 1 and 12, respectively.

As shown in FIG. 14, the locking spring 40 is formed by bending both ends of a strip of a conductive material having elasticity, so that the locking piece 40b and the contact piece 4 are provided at both ends of the central piece 40a.
0c is formed. The center piece 40a contacts the support piece 37b of the terminal plate 37. The locking piece 40b inclines toward the tip end edge from the connecting portion with the central piece 40a so as to approach the contact piece 37a of the terminal plate 37. The contact piece 40c is bent in a substantially S shape, and the locking piece 40b and the contact piece 40c provided on the locking spring 40 are the contact piece 37a of the terminal plate 37.
To face. Further, as shown in FIG. 15, the release button 41 is formed of a synthetic resin material having an insulating property in a substantially cross shape, and through the release hole 19, the first and second storage chambers 11, 1 are provided.
It is provided with an operating piece 41a led out of the container body 1 from 2 and a pair of releasing pieces 41b, 41b abutting on the respective locking pieces 40c, 40c of the pair of locking springs 40, 40. And
As shown in FIG. 14, the corners of the tip ends of the release pieces 41b, 41b are brought into contact with the locking pieces 40b of the locking springs 40, respectively, and the contact pieces 37a, 37a are moved in the front-back direction of the body 1. It is stored and arranged so that it can move freely.

When connecting an electric wire to this power source terminal,
When the stripped electric wire is inserted from the electric wire insertion port 18, the spring force of the locking spring 40 causes the locking piece 40 of the locking spring 40 to move.
The electric wire is sandwiched between the contact piece 40b and the contact piece 40c and the contact piece 37a of the terminal plate 37, and the tip edge of the locking piece 40b bites into the electric wire to prevent the electric wire from falling off. Therefore, only by inserting the stripped electric wire into the electric wire insertion port 18, the electric wire is held and electrically connected to the terminal board 37. Further, when the electric wire connected to the power source terminal portion is removed, the operation button a of the release button 41 led out of the body 1 through the release hole 19 is pressed by the tip of a tool such as a flat-blade screwdriver to release the release button. As the reference numeral 41 moves toward the front of the body 1, the release pieces 41 b, 41 of the release button 41
b are locking pieces 40b and 40 of locking springs 40 and 40, respectively.
b, press the lock pieces 40b, 40b to the terminal plates 37, 37
The locking pieces 40b, 40b are bent away from the contact pieces 37a, 37a so that the locking pieces 40b, 40b separate from the electric wire, and the electric wire can be easily pulled out.

Here, in the present embodiment, the terminal plates 37, 37 of the power supply terminal portion are connected to each other by the contact pieces 37a, 37a.
Since the contact pieces 37a, 37a and the support pieces 37b, 37b are arranged so as to be substantially parallel to each other and are arranged in a line, the two locking springs 40, 40 are locked to each other by the locking pieces 40b,
40b and contact pieces 40c, 40c can be stored in the first and second storage chambers 11, 12 arranged in series so as to face each other. That is, in the conventional quick-connect terminal structure, as shown in FIG.
7'and 37 'are contact pieces 37 by integrally forming a support piece 37b'.
a ', 37a' are formed so as to be lined up on the same plane, and the two locking springs 40, 40 are arranged and arranged side by side in parallel, so that the vertical dimension of the locking springs 40, 40 (contact The width dimension of the storage chamber increases in accordance with the bending direction of the piece 37a and the locking piece 37b. On the other hand, in this embodiment, as described above, the two locking springs 40, 40 are arranged side by side in series and housed, so that the first and second housing chambers 11 are different from the conventional quick-connect terminal structure. , 12 can be reduced in width dimension, and the body 1 can be downsized.
Further, in the above-mentioned conventional quick-connect terminal structure, when the release button 41 'is pressed by the tip of the tool inserted from the release hole, the release button 41' falls toward the lock spring 40 and moves while the lock piece is moved. Since 40b 'is designed to be bent, the space for moving the release button 41' is increased, but in the present embodiment, the release button 41 moves linearly along the wire insertion direction. However, since it has a structure in which the locking piece 40b is bent, the movement space of the release button 41 is smaller than that in the conventional quick-connect terminal structure described above, which also allows the body 1 to be downsized. is there.

By the way, when the electric wire is removed in the conventional quick-connect terminal structure, the body 1 is held by one hand and the tip of the tool held by the other hand is inserted into the release hole to operate the release button 41 '. It is difficult to pull out the electric wire from the electric wire insertion port while operating the release button 41 ', and it is difficult for one construction worker to perform the work. Therefore, in the present embodiment, as shown in FIGS. 3C and 3D, a recess 49 communicating with the release hole 19 at one end side is provided around the release hole 19 on the outer bottom surface of the body 2, and the release button is also provided. The tip end of the operation piece 41a of 41 is advanced into the recess 49 from the release hole 19 within a range that does not project from the outer bottom surface of the body 2.

The conductive member 38A 'is formed by punching a conductive plate material into the shape shown in the development view of FIG. 20 and bending a predetermined portion (see FIG. 18). Although illustration is omitted, the conductive member 38B ′ is also formed by punching into a shape similar to the developed view of FIG. 20 and bending a predetermined portion, although the shape of the details is different. Further, the blade receiving member 2 in which the flat blade blade receiving spring 35 and the round pin blade blade receiving spring 36 are integrally formed
As shown in FIG. 19, 1'is provided with a positioning portion 35c formed of a flat plate-like protrusion from the side edge of the connecting portion connecting the rear edges of the spring pieces 35a and 35b.

Thus, at both ends of the conductive member 38A ', the tongues 38a, 38a,
38b is extended, the protrusions (not shown) provided on the blade receiving members 21 ', 21' are inserted into the holes 38c penetrating the tongues 38a, 38b, and the blades are caulked. The receiving members 21 ', 21' are fixed to the tongues 38a, 38b to form the terminal block A '. Here, a pair of columnar protrusions 38d and 38d are provided on one tongue piece 38a so that the positioning portion 35c is sandwiched between the protrusions 38d and 38d as shown in FIG. The blade receiving member 21 'is positioned.

Further, as shown in FIG. 23, the blade receiving member 21 '
Blade receiving springs 3 for flat blades and round pin blades
If the spring pieces constituting 5, 36 are connected by bending one conductive plate, compared to the case where two types of blade receiving springs 35, 36 are formed individually. There is an advantage that processing becomes easy. Alternatively, as shown in FIG. 24, the blade receiving spring 36 for a round pin type blade is composed of a pair of spring pieces 36a, 36a that flexibly oppose each other, and the side edges of the pair of spring pieces 36a, 36a are bent. The flat blade blade receiving spring 35 ′ may be integrally formed by integrally providing spring pieces 35a ′ that receive the flat blade between the spring pieces 36a and side edges of the spring 36a. Also in this case 2
There is an advantage that processing is easier than in the case where the blade receiving springs 35 and 36 of different types are individually formed.

If the structure in which 7a and 37a are connected to each other from the direction along the axis of the electric wire at one end side along the axial direction (insertion direction) of the electric wire, the terminal plates 37 and 37 (contact piece 3
Since 7a, 37a) can be formed by a uniform plane, there is an advantage that a large contact area can be secured. However,
In this case, the expanded shape of the conductive member 38A ″ is shown in FIG.
Since the shape is as shown in the development view of the contact piece 3 as described above,
It is said that the shape in which the conductive member 38A ′ is connected in the structure in which 7a and 37a are connected to each other at one end side along the axial direction of the electric wire by a connecting piece 37c from a direction substantially orthogonal to the axial direction of the electric wire can improve the planing efficiency There are advantages (Fig. 20)
reference). Moreover, the notches 37d and 37d for bending are required at the connection portion between the connecting piece 37c and the contact pieces 37a and 37a. These notches 37d and 37d are chained when the contact pieces 37a and 37a are in the wire connection state. By providing the lock spring 40 at a position where it is not pushed, the electric wire and the contact piece 37
It is possible to minimize the influence on the contact property with a and 37a (see FIG. 14).

In the seventh storage chamber 17 of the body 2, blade receiving members 22, 22 for receiving the blades of the ground electrode inserted into the blade insertion holes 28 for the ground electrodes of the insertion portions 26, 26, respectively, A pair of ground electrodes 514, 51 exposed on the side surface of the C-type plug P5

Here, as shown in FIG. 27, the grounding terminal portion, the blade receiving members 22, 22, and the grounding member 42.
A and 42B form a grounding terminal block C.

As shown in FIG. 28A, the grounding terminal block C is a conductive member 38C which is formed in a generally U-shaped plan view.
And the blade receiving members 22, 22 fixed to the conductive member 38C. The conductive member 38C is a conductive plate material as shown in FIG.

44 and the grounding members 42A, 42A projecting forward from one end edges of both longitudinal ends of the horizontal piece 43b are integrally formed. Here, the grounding members 42A, 42A are inclined toward the terminal plate 44 side toward the tips, and the tip ends are curved to the side opposite to the terminal plate 44, and the grounded electrodes 514 of the C-type plug P5 are curved at the bent tips. Contact with.

The grounding terminal portion includes the terminal plate 44 and the lock spring 4.
It has a quick-connect terminal structure composed of 0 and a release button 41, and is provided with a terminal for connecting a ground wire and a terminal for feed wiring for sending the ground wire to another outlet or the like.
Each terminal board 44 has a strip-shaped contact piece 44 that contacts the ground wire.
a and a support piece 44b supporting the locking spring 40 are formed in a substantially U shape in a plan view so as to face each other substantially parallel to each other, and the contact pieces 44a, 44a of each other face each other substantially parallel to each other. One end side is connected by a connecting piece 44c. Further, the substantially L-shaped extending pieces 44d and 44d are respectively extended outward from the rear end side edges of the supporting pieces 44b and 44b, and the supporting pieces 44b and 44b are extended from the one edge of each extending piece 44d and 44d. Substantially L-shaped fixing pieces 44e, 44e are provided so as to stand up along. This fixed piece 4
Cylindrical protrusions 44f and 44f protruding outward are arranged in parallel on the outer side surfaces of 4e and 44e.

On the other hand, the blade receiving member 22 includes a ground electrode blade receiving spring 45 for receiving the plug blade 501 for the ground electrode of the A-type plug P2, and the other ground member 42B as shown in FIG. The ground electrode blade receiving spring 45 has a pair of spring pieces 45a, 4a, one end side of which is connected by a connecting piece 45b and flexibly faces each other.
5a, the gap between the pair of spring pieces 45a, 45a becomes narrower as it gets closer to the tip, and the tip is bent so that the distance between them widens.
It is easy to insert the blade for the ground electrode between 5a and 45a. The pair of spring pieces 45a, 45a are connected by a connecting piece 45b from a direction substantially orthogonal to the insertion direction of the blade, and the grounding member 42B is connected to the side edge of the connecting piece 45b. 45 and the ground member 42B are integrally formed. Therefore, the number of parts can be reduced and the assemblability can be improved as compared with the case where the ground electrode blade receiving spring 45 and the ground member 42B are formed separately.

The ground member 42B is inclined toward the tip toward the ground electrode blade receiving spring 45, and the tip portion is curved to the side opposite to the ground electrode blade receiving spring 45. The curved tip portion is C-shaped. It contacts the ground electrode 514 of the plug P5. Then, circular through holes 45c, 45c are provided in the connecting piece 45b, and the conductive member 3 is provided in the through holes 45c, 45c.
The protrusion 44f protruding from the fixing piece 44e of 8C is inserted, and the blade receiving member 22 is fixed to the fixing piece 4 by caulking the protrusion 44f.
It sticks to 4e. Here, rectangular notches 45d and 45d are provided at the rear end edges of the spring pieces 45a and 45a, respectively, and as shown in FIG. 31, these notches 45d and 45d.
d is fitted to the extending piece 44d of the terminal board 44. That is, since the pair of spring pieces 45a, 45a are connected to each other by the connecting piece 45b from the direction substantially orthogonal to the insertion direction of the blade, the ground electrode blade receiving spring 45 is formed.
Although the tip portion of a tends to open easily, the spring pieces 45a, 45a can be fitted by fitting the notches 45d, 45d provided in the spring pieces 45a, 45a to the extension piece 44d as described above.
Is prevented from opening more than necessary, and excessive deformation of the spring piece 45a can be prevented.

Further, the blade receiving member 22 of this embodiment is shown in FIG.
As shown in the developed view of FIG. 2 (b), it is formed by bending a conductive plate punched out in a substantially mountain shape, and as shown in FIG. 33 (a), a pair of spring pieces 45a, 45a are formed as blade blades. Compared with the structure in which the connecting piece 45b is connected from the direction along the insertion direction, there is an advantage that the planing can be made more efficient. That is, FIG.
The blade receiving member 22 ′ having the structure shown in FIG.
Since it is formed by bending a conductive plate punched out into a substantially T-shape as shown in the developed view of FIG. 3, the wasteful portion X of the plate material is larger than that of the blade receiving member 22 of the present embodiment. turn into. However, the blade receiving member 22 'having the above structure has an advantage that the spring stroke of the ground contact member 42B' can be lengthened and can sufficiently cope with a large displacement amount.

By the way, the conductive member 38C 'corresponding to the blade receiving members 22', 22 'having the structure shown in FIG.
It is formed by punching a conductive plate material (conductive plate) into the shape shown in the development view of FIG. 34 and bending a predetermined portion (see FIG. 35). The conductive member 38C ′ having such a shape is easily processed because the bending directions of the bent portions of the conductive plate are aligned. On the other hand, since the conductive member 38C of the present embodiment has uneven bending directions at the bent portions of the conductive plate as shown in the development view of FIG. 31, it is not processed as compared with the conductive member 38C ′. Although less easy, there is an advantage that the wasted portion X of the plate material is relatively reduced and the plate cutting can be performed efficiently.

Further, in the present embodiment, the blade receiving spring 4 for the ground electrode is used.
5 and the ground receiving member 42B are integrally formed into blade receiving members 22, 2
Although 2 is formed separately from the grounding terminal portion, if both are integrally formed as shown in FIG. 36, the fixing work such as caulking becomes unnecessary, and the number of parts can be reduced and the assemblability can be improved.
However, the grounding terminal block C'in which the blade receiving members 22 and 22 are integrated with the grounding terminal portion is formed by punching a conductive plate into a shape shown in the development view of FIG. 37 and bending a predetermined portion. However, since there are many places where the conductive plate is wasted in such a shape, the blade receiving member 22,
Forming 22 and the grounding terminal separately is advantageous in that the planing can be made more efficient.

The grounding terminal block C configured as described above accommodates the blade receiving members 22, 22 in both ends of the seventh storage chamber, and the terminal plates 44, 44 in the longitudinal direction of the contact piece 44a. The locking spring 40 is aligned with the front-back direction of the body 1 (the insertion direction of the ground wire with respect to the wire insertion port 18).
Further, it is housed in the body 2 so as to be housed in the substantially central portion of the seventh housing chamber 17 together with the release button 41. At this time,
The vertical piece 43a of the connecting portion 43 is placed on the mounting table 7a projecting forward from the partition wall 7 in the center of the body 2 and the boss 9, and the horizontal piece 43b of the connecting portion 43 passes over the side wall of the body 2. It is arranged outside the body 2. By mounting the connecting portion 43 on the mounting table 7a and crossing the power source side terminal portion in this manner, the insulation distance between the grounding terminal block C and the power source terminal portion can be increased, and the lateral side of the connecting portion 43 can be further increased. Piece 43
b is disposed outside the body 1 and is placed between the power source side terminal portion and the body 1
By interposing the side wall of the (cover body 3a), a large insulation distance can be secured between the ground members 42A, 42A and the power supply terminal portion. Moreover, the pair of ground members 42A, 42A
Since the horizontal piece 43b for connecting A is arranged near the front of the side surface of the body 1 not provided with the electric wire insertion port 18, the connecting portion 43 is arranged in the vicinity of the electric wire insertion port 18 for inserting an electric wire. Since it is not present, there is no risk that the stripped electric wire will contact the connecting portion 43 and cause a ground fault.

Further, as shown in FIG. 38, if the body 2 and the cover 3 are coupled with the assembly screws 10, the body 1 is assembled.
The grounding members 42A, 42A provided at both ends of the horizontal piece 43b are inserted into the slits 29a, 29a of the cover body 3a, respectively, so that the tips thereof face the recesses 25, 25. In addition, the boss 9 is provided at the end of the vertical piece 43a on the side of the horizontal piece 43b.
Has a hole 43c communicating with the screw insertion hole 9a and through which the assembly screw 10 is inserted, and the vertical piece 43a is assembled with the assembly screw 10 when the body 1 is assembled by connecting the body 2 and the cover 3.
It is fixed to the body 1 by. Here, as shown in FIG. 5C, a plurality of ribs 24a are arranged in parallel on the back surface side of the plate portion 24 of the cover 3,
Fitting grooves 24b that fit with the end edges of the lateral pieces 43b are formed at the ends of the ribs 24a on the cover body 3a side. That is, the horizontal piece 4 is fitted by fitting it into the fitting groove 24b.
Since the rib 24a contacts the rib 3b and the bending of the horizontal piece 43b is restricted, it is possible to prevent the contact pressure between the grounding electrode of the C-type plug P5 and the grounding member 42A from being lowered by the bending of the horizontal piece 43b. .

By the way, by forming the blade insertion opening 27 into a shape in which the flat blade insertion opening 27a and the round pin blade insertion opening 27b communicate with each other, the opening area of the blade insertion opening 27 becomes relatively large. Therefore, there is a possibility that a conductive foreign substance may be inserted into the blade insertion opening 27 without connecting the plug, resulting in an accidental electric shock. Therefore, in the present embodiment, when the plug is not connected, the blade insertion opening 27 of the insertion portion 26,
27 is closed by the door 46 and the door 46 is opened by the plug blade of the plug to open the blade insertion ports 27, 27. When the plug is not connected, the blade insertion port 27, 27 is closed by the door 46. This prevents the conductive foreign matter from being accidentally inserted and an electric shock accident to occur.

That is, in this embodiment, the two doors 46, 46 and the blade insertion opening 2 are provided inside the cover body 3a.
Coil springs 47, 47 that elastically bias the doors 46, 46 in the direction of closing the doors 7, 27, and the door in the direction along the front surface of the body 1 (direction orthogonal to the insertion direction of the blade to the blade insertion opening 27). Inner frames 47, 47 for slidably supporting 46 are housed. The middle frame 47 is made of an insulative synthetic resin molded product, and as shown in FIG. 39, openings 48a, 48a for exposing the blade receiving member 21 to the front are provided on both sides,
A slide groove 48b is provided on the front side of the center, and a protrusion 48c for fitting with the fitting grooves 6a, 8a formed on the front surfaces of the partition walls 6, 8 of the body 2 is provided on the rear side of the center so as to project. The ridges 48c are fitted in the fitting grooves 6a, 8a and placed on the partitions 4-8. Further, the coil springs 47 are provided at both ends of the slide groove 48b on the front center side of the middle frame 48.
A fixing portion 48d that fixes one end of the door and a stopper 48e that restricts the movement amount of the door 46 are provided in a protruding manner.

The door 46 is made of an insulating synthetic resin molded product, and as shown in FIG.
ribs 46b provided with a and 46a and projecting from the center rear surface side
By being fitted into the slide groove 48b of the middle frame 48, it is slidably mounted on the front side of the middle frame 48. Also,
A fixing projection 46c for engaging and fixing the other end of the coil spring 47 is provided on the front side of the center of the door 46, as shown in FIG.
As shown in, the direction in which the door 46 contacts the stopper 48e of the middle frame 46 by the coil spring 47 whose ends are fixed to the fixing portion 48d of the middle frame 48 and the fixing protrusion 46c of the door 46, that is, the blade insertion slot 27, It is elastically biased in a direction of closing 27. Further, the front surfaces of both blade pieces 46a, 46a and the front surfaces of the portions in the vicinity of the blade pieces 46a, 46a are inclined surfaces 46d, 46e inclined rearward in the biasing direction. Here, the rib 46b of the door 46 is formed in a semicircular cross section in a direction orthogonal to the longitudinal direction (the sliding direction of the door 46), and the door 46 swings with respect to the middle frame 48 with the rib 46b as a fulcrum. It is free (see Figure 42).

On the other hand, on both sides of the front surface of the middle frame 48 facing the respective wing pieces 46a, 46a of the door 46, when the door 46 swings and tilts as described above, it leans toward the middle frame 48. Stepped portions 48f, 48f are formed which come into contact with the ends of the blades 46a and prevent the sliding movement of the door 46. That is, the door 46 can be slid only when it is not tilted with respect to the middle frame 48.

When the body 2 and the cover 3 are combined to assemble the body 1, the openings 48a, 48a of the middle frame 48 are formed.
The blade receiving members 21 and 21 face each other, and both wing pieces 46a and 46a of the door 46 are elastically biased by the coil spring 47 and are positioned in front of both opening portions 48a and 48a of the middle frame 48, and the cover 3 is plugged. The blade insertion ports 27, 27 are closed (see FIG. 41).
In this state, the plug blade of the plug is inserted into the pair of blade insertion holes 27, 27.
, The inclined surfaces 46d or 46e of the door 46 are pressed by the respective blades, and the door 46 is slid against the spring force of the coil spring 47, so that the blade insertion ports 27, 2 are inserted.
7 is opened, both blades reach the positions of the blade receiving members 21, 21 through the openings 48a, 48a of the inner frame 48, and if the blades are flat blades, the blade receiving springs 35, 35 for flat blades are provided. If it is a round pin type blade, the blade receiving spring for the round pin type blade 3
6 and 36, and can be connected to the blade receiving members 21 and 21 (see FIG. 43). In addition, the blade receiving member 2 by removing the plug
When the blades are separated from the blades 1, 21, the door 46 is returned to the original position by the spring force of the coil spring 47, and the blade insertion ports 27, 27 are closed again (see FIG. 41).

On the other hand, the pair of plug blades of the plug is the blade insertion slot 2
When not inserted into 7 and 27 at the same time, that is, when only one blade is inserted into one blade insertion port 27,
The door 46 is not opened and only one plug blade is not connected to the blade receiving member 21. That is, when only one blade is inserted, the blade 4 on one side is
Since only 6a is pressed, the door 46 swings as described above, and the blade piece 46a pressed by the blade is inclined toward the inner frame 48 and abuts the step 48f of the inner frame 48. As shown in FIGS. 44 and 45, the sliding movement of the door 46 is blocked and the blade insertion holes 27, 27 are not opened.

Thus, in this embodiment, the C-type plug P3
To P5, a pair of round pin type blades 502 are inserted into the circular pin type blade insertion holes 27b of the blade insertion ports 27, 27, and when connecting the A type plug P1, a pair of circular pin type blades 502 are inserted. When inserting the flat blades 500, 500 into the flat blade insertion openings 27a, 27a, or when connecting the A-type plug P2 with a ground electrode, insert the flat blades 500, 500 into the flat blades. Mouth 2
It is only necessary to insert the plug blade 501 for the ground electrode into the plug blade insertion opening 28 for the ground electrode while inserting it into 7a, and it is possible to connect a plurality of types of plugs having different shapes of contacts, arrangement of the ground electrode, etc. Is. The ground electrodes 514 and 514 of the C-type plug P5 with a ground electrode come into contact with the ground members 42A and 42B facing the inside of the recess 25 through the slits 29a and 29b to be in contact with each other.

Here, in the present embodiment, the pair of ground members 42A, 42B are separated from each other in the recesses 25, 25 so as not to interfere with the fixing screw, that is, the screw insertion hole 33 for inserting the fixing screw. By arranging on a straight line that is substantially orthogonal to the straight line connecting the centers of 33, interference between the fixing screw and the grounding members 42A, 42B is eliminated, and the grounding members 42A, 4
It prevents deformation of 2B and facilitates construction work. Even if the straight line connecting the ground members 42A, 42B and the straight line connecting the centers of the screw insertion holes 33, 33 are not orthogonal to each other, as shown in FIG.
The same effect can be obtained by arranging 2B in the recesses 25, 25 at positions apart from each other so as not to interfere with the fixing screw. However,
When the positional relationship in which the straight line connecting the ground members 42A and 42B and the straight line connecting the centers of the screw insertion holes 33 and 33 are orthogonal to each other as in the present embodiment, there is an advantage that there is no discomfort in the plug connection direction.

By the way, in this embodiment, each blade insertion port 2
7, 27 are formed so that the straight lines connecting the center of the flat blade insertion opening 27a and the center of the round pin blade insertion opening 27b are not parallel to each other, but this eliminates the following problems. The purpose is to do. That is, FIG. 47 (b)
As shown in FIG. 5, each blade insertion opening 27, 27 has a shape in which a circular round pin type blade insertion opening 27b communicates with one side edge of the central portion in the longitudinal direction of a rectangular flat blade insertion opening 27a. When the straight lines connecting the center of the blade insertion opening 27a and the center of the round pin type blade insertion opening 27b are made parallel to each other, the contact member 42B on the lower side and the ground electrode are not connected to the plug. When it is connected to a plug having a relatively large size such as an A-type plug P2 with a grounding electrode, the plug blade insertion opening 28 of FIG.
As shown in 7 (b), the center of the outer shell of the plug (indicated by a two-dotted line in the figure) and the center of the recess 25 are displaced from each other, so that the plug may not be inserted into the recess 25. Therefore, in the present embodiment, each blade insertion opening 27, 27 is formed in the above-described shape, and the position of the blade insertion opening 28 for the ground electrode on the bottom surface of the recess 25 is relatively shifted upward. The straight blades connecting the center of the flat blade insertion opening 27a and the center of the round pin blade insertion opening 27b in each blade insertion opening 27, 27 are prevented from being parallel to each other, and the flat blade insertion opening 27a,
The center positions of 27a and the grounding blade insertion hole 28 are displaced from the center position of the recess 25. as a result,
Even if the outer shape is large like the A-type plug P2 with a ground electrode, it can be inserted into the recess 25 (see FIG. 47).
(Indicated by a two-dot broken line in (a)), the number of connectable plugs can be increased.

In this embodiment having the above-described structure, the rear portion of the plate portion 24 of the body 1 is embedded in the switch box embedded in the wall, and the fixing screw is inserted into the screw insertion hole of the plate portion 24. It is fixed to the wall surface by being inserted into 33, 33 and screwed into the screw hole of the switch box. Then, the locking pieces 104 projecting from the back surface of the decorative plate 100 are inserted into the locking holes 24c provided in the vicinity of the four corners of the plate portion 24, and the locking claws 104a projecting from the tip end of the locking pieces 104 are respectively inserted. Receiving part 24d on the periphery of the locking hole 24c
The decorative plate 100 is detachably attached so as to cover the front surface of the plate portion 24 by locking the plate 24 to complete the construction.

As shown in FIG. 48, the decorative plate 100 is made of a synthetic resin molded product having an insulating property, is a substantially rectangular shape having four R corners and covers the front surface of the plate portion 24, and the main portion 101. A side wall portion 102 that projects rearward from the peripheral edge of 101 over the entire circumference is integrally formed. The locking pieces 104 are provided so as to protrude from the vicinity of the four corners on the back surface side of the main portion 101. A rectangular opening window 103 is provided in the center of the main portion 101, and the front side of the cover body 3a is inserted into the opening window 103 to expose the front surface of the body 1 having the recesses 25, 25.
