[0019]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an example of an embodiment. The illustrated outlet is formed as an embedded wiring device attached to a wiring box via a mounting frame. The size of the module is standardized as one module in the embedded wiring device.

A case 1 constituting an outer shell of the outlet includes a body 10 having an open surface,
And a cover 11 attached to the opening side of the "0". The inside of the body 10 is partitioned into two storage portions 13, 13 by a partition wall 12, and each storage portion 13 includes a release button 29, two locking springs 26, 26, and the blade receiving spring 2. Each is housed.

The blade receiving spring 2 is formed of a conductive metal material having elasticity. The blade receiving spring 20 has a pair of elastic pieces 22, 22 facing each other, and a blade receiving portion 20 for a round pin type plug blade. A blade receiving portion 21 for a flat plug blade, comprising a side edge on one side of the side 22 and an elastic piece 23 facing the side edge, and a quick-connecting terminal is constituted by the locking springs 26, 26. The quick-connect terminal is connected to the quick-connecting terminal by inserting the end of the electric wire from the electric wire insertion hole formed on the back side of the body and stripping the coating of the electric wire.
The release button 29 is for releasing this connection, and the tip of a screwdriver or the like is inserted through a release hole 19 opened on the back of the body 10 to move the release button 29 to move the locking spring 26 to the lock spring 26. By bending, the connection of the wire can be released by loosening the pressing of the wire against the terminal plate portion 25 by the edge of the locking spring 26 and pulling out the wire.

The cover 11 attached to the opening side of the body 10 has a pair of terminal insertion holes 14 on its surface. Each of the terminal insertion holes 14 is formed by integrating an insertion hole 14a for a round pin type blade and an insertion hole 14b for a flat type blade, and inserts a pair inside the pair of insertion holes 14a, 14a. Holes 14b, 14b are located.

Inside the cover 11, a pair of doors 4, 4 and a pair of springs 5, 5 and a middle frame 3 are accommodated. The middle frame 3 has a pair of through holes 31, a groove 30 located between the through holes 31, 31, and protrusions 32, 32 located on both sides of each through hole 31. As shown in FIG. 8, the cover 1 is engaged with a projection 17 provided on the inner wall of the cover 11.
1 can be temporarily fixed. The pair of doors 4 and 4 and the pair of springs 5 and 5 are disposed between the inner frame 3 and the inner surface of the cover 11.

A pair of doors 4 having the same shape is provided with wings 41, 41 projecting to both sides, and a bar-shaped piece 40 protruding to the other door 4 side. It is provided at a position closer to the wing piece 41 side than the center,
When the two doors 4, 4 are combined with each other, a bar-shaped piece 40,
40 are lined up and slidable with each other. The upper surface of each of the wing pieces 41 and 42 is formed as an inclined surface 43 in which the other door 4 side becomes lower.

The doors 4, 4 have the bar-shaped pieces 40, 40 housed in the grooves 30 of the middle frame 3, and have springs 5, 5 which are coil springs disposed between the outer surface thereof and the inner wall of the cover 11. The doors 4 and 4 are housed in the cover 11 in a state where the doors 4 and 4 are pressed by the springs 5 and 5 so as to be in contact with each other.

The cover 11 containing the middle frame 3 and the doors 4 and 4
Is attached to the body 10 by engaging projections 10a provided on the outer surfaces of both ends of the body 10 with engagement holes 61 provided in the elastic pieces 60 projecting rearward from the outer surfaces of the both ends. However, when the assembly is performed by locking the front end of the assembly frame 6 covering the cover 11 to the outer surface of the body 10, the blade of the blade receiving spring 2 is inserted into the through hole 31 of the middle frame 3 as shown in FIG. While the receiving portions 20 and 21 are located, the middle frame 3 engages with the partition wall 12 in the body 10 to separate the two-blade receiving springs 2 from each other, and short-circuiting occurs due to swarf generated by opening and closing of the plug. Is prevented from occurring. The blade receiving portion 2 is provided inside the through hole 31.
By positioning 0 and 21, abnormal opening of the blade receiving spring 2 is prevented. Reference numeral 35 in FIG. 8 indicates an abnormal opening preventing portion for the blade receiving portion 21. The doors 4 are located between the insertion hole 14 of the cover 11 and the blade receiving spring 2.

That is, the wings 41 of one door 4 slightly cover the wings 42 of the other door 4 so that no gap is formed between the doors 4 and 4 so that the doors 4 , 5, the doors 4, 4 closed in this way are located between the insertion hole 14 and the blade receiving spring 2,
As shown in FIG. 2, the blade receiving spring 2 located behind the insertion hole 14 is hidden.

Here, a positioning rib 18 protrudes from the inner surface of the cover 11 as shown in FIG. 7, and the door 4 urged by the spring 5 makes the contact surface 46 shown in FIG. , The positions of both doors 4 and 4 in the closed state are determined.

In this state, the plug blade of the plug is inserted into both insertion holes 14.
, Each blade pushes the inclined surface 43 of the wings 41, 42 of the doors 4, 4, thereby moving the door 4 against the spring 5 and widening the space between the doors 4, 4. For this reason, the blade reaches the blade receiving spring 2 and is inserted into the blade receiving portion 20 if the blade is of a round pin type, and is inserted into the blade receiving portion 21 if the blade is of a flat type. When the plug is removed, the doors 4 and 4 return by the bias of the springs 5 and 5 to close the insertion hole 14 again.

In this outlet with door, when the pair of blades of the plug are not inserted at the same time, that is, as shown in FIG. 10, when only one of the blades 70 is inserted, the doors 4, 4 are opened. , One of the blades 7
The state that only 0 is inserted into the blade receiving spring 2 does not occur. That is, when only one of the blades 70 is inserted, the two doors 4, 4 are rod-shaped pieces 40, 4 received by the grooves 30 of the middle frame 3, as shown in FIG.
It is pushed by the blade 70 around the center 0 and tilts to one side, and as shown in FIGS. 10 and 11,
The wing pieces 41, 42 enter between the projections 32, 32 of the middle frame 3, and even if the blade 70 pushes the inclined surface 43 to push the doors 4, 4 open, the wings 41, 42 are in contact with the projection 32, which is a stopper. It does not open due to interference. When the blade 70 is inserted, the door 4 also tries to tilt in the left-right direction in FIG. 6 because the blade 70 hits the inclined surface 43, but this inclination is prevented by the bar-shaped piece 40.

The rib 47 provided on the surface on the side of the middle frame 3 of the door 4 where the flat blade 70 comes into contact has a large resistance to the door 4 when the flat blade 70 is inserted. It is a reinforcing rib provided in view of the above.

A pair of coil springs 5, 5
Is provided on both sides instead of between doors 4 and 4.
This has the meaning that a short circuit between different poles does not occur even if the springs 5, 5 are broken by opening and closing the doors 4, 4. The portion of the door 4 which receives the spring 5 has a hole 44 into which a boss 45 projects, as shown in FIGS.
When the spring 5 is fitted into the hole 44,
The spring 5 engages with the boss 45 having a thicker root. When assembling, the spring 5 is assembled into the cover 11 with the door 4 assembled, but the spring 5 does not fall off the door 4 and the assembling workability is good.

When the two blades 70, 70 are inserted at the same time, but are inserted diagonally, the doors 4, 4 are inclined, so that only one of the blades 70 is inserted. The doors 4 and 4 are not opened, but from this state, if the locked force F1 is removed and the other force F2 is increased, the doors 4 and 4 return to the original state and the lock is released. When the blades 70, 70 face each other, the doors 4, 4 are opened by further pushing the blades 70, 70, and the blades 70, 70 are connected to the blade receiving springs 2, 2. However, if the force F2 is increased without removing the force F1, the doors 4, 4 will be further applied in a locked state, so that the two doors 4, 4 are viewed from the front in a parallel state. , It spreads out in the shape of a letter "C", and the insertability deteriorates. Also, when the loads of the forces F1 and F2 are high, a large bending moment is applied to the bar-shaped pieces 40 of the doors 4 and 4, which may cause a break.

For such a point, stoppers may be provided at the four inner corners of the cover 11. That is, FIG.
13, and the wings 41 of the inclined doors 4, 4, as shown in FIG.
The protrusion 16 is provided to prevent the doors 4 and 4 from opening by coming into contact with the distal end of the projection 42. As shown in FIG.
Since both ends of the door 4 are prevented from moving in the opening direction by the projections 32 and 16, the doors 4 and 4 do not spread in the shape of a letter "C". If the engagement between the projection 16 of the cover 11 and the door 4 is released earlier than the engagement between the projection 32 of the middle frame 3 and the door 4, the door 4 will have a “C” shape. To avoid this, the engagement depth between the projection 16 and the door 4 is set to be larger than the engagement depth between the projection 32 and the door 4. Thereby, the plug insertion property can be improved and the doors 4 and 4 can be prevented from being damaged.

FIG. 15 shows another example. This is the cover 11
, A taper 48 is provided on the upper surface of both ends of the door 4. Because the inclination angle β of the door 4 can be increased even in a small space, and the contact area between the door 4 and the projection 16 can be increased,
Prevention of one-edge insertion can be performed more reliably.

Of course, as shown in FIG. 16, it is effective to provide a taper 49 also on the lower surfaces at both ends of the door 4. In this case, the inclination angle of the door 4 can be further increased, and Since the contact area with the protrusions 32 and 16 can be increased, the prevention of single-edge insertion can be improved.

Instead of providing a taper on the door 4 side, the protrusion 3
A taper may be provided on the upper surface of the second 2 or the lower surface of the protrusion 16. FIG. 17 shows a case where a taper 33 is provided on the projection 32 in accordance with the inclination of the door 4. Although the inclination angle of the door 4 cannot be increased, even when the inclination angle of the door 4 is small, the contact area between the door 4 and the projection 32 can be increased, and the prevention of single-edge insertion can be enhanced. it can. FIG. 18 shows a configuration in which a taper 48 is provided on both upper surfaces of the door 4 and a taper 17 is provided on the lower surface of the projection 16.

FIGS. 19 and 20 show another example. This is a symmetrical configuration of the wings 41, 42 of the door 4, and also eliminates the portion where the wing 41 overlaps the other door 42. Wing piece 4
1 and the inclined surfaces 43 of the wing pieces 42 have the same angle α, so that when the blade 70 is inserted, the left and right doors 4 and 4 move uniformly, and the insertability of the blade 70 is improved. Get better.
Further, since the portions where the thickness of the wing pieces 41 and 42 are small can be eliminated, the strength of the door 4 is also increased.

FIGS. 21 and 22 show still another example of the door 4. The door 4 here has a bar-shaped portion 40 at the lower center in a semicircular shape, and when the doors 4 and 4 are combined with each other so that the bar-shaped pieces 40 and 40 are arranged in the axial direction. In addition, the groove 30 for receiving the bar-shaped piece 40 in the middle frame 3 is also formed to have a semicircular cross section so that the door 4 can be smoothly tilted left and right. Since the initial inclination due to the fulcrum position of the door 4 being displaced from the center can be eliminated, the insertability of the plug is improved. Also, since there is no portion of the rod 40 protruding from the door 4, Since there is no possibility that the bar-shaped piece 40 is broken, the assemblability and the formability are also improved.

In the above embodiment, the insertion hole 14 is closed by the pair of doors 4 and 4. However, the insertion hole 14 is closed only by the single door 4. You may. However, when the insertion hole 14 is closed by combining the two doors 4 and 4, the evacuation space of the door 4 when the insertion hole 14 is opened can be reduced, so that a single module as in the illustrated example is used. This is advantageous when the door 4 is provided.

In using a pair of doors 4 and 4, the number of types of parts is reduced by using ones having the same shape and the same size here. It doesn't have to be big.
