DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiments described below, unless otherwise specified, the directions of FIG. 2 are defined in the vertical and horizontal directions, and the front in FIG. 2 is referred to as the front.
Therefore, the right end in FIG. 2 is the rear end. (Embodiment 1) The configuration of this embodiment is shown in FIGS. The container 1 has a rectangular parallelepiped body 10 having an open front surface made of a thermosetting synthetic resin (for example, urea resin) having excellent tracking resistance, and has elasticity and excellent tracking resistance. It is formed by combining a synthetic resin (for example, polybutylene terephthalate = PBT) with a cover 20 formed in a rectangular parallelepiped shape having an open rear surface. The container 1 has a prescribed unit dimension described later.

A pair of assembling claws 11 project from both upper and lower end surfaces of the body 10. On the other hand, shoulders 21 project from both upper and lower ends of the cover 20, and assembly pieces 22 project from the rear edge of each shoulder 21 toward the body 10. Each assembly piece 22 has an assembly claw 11 provided on the body 10.
A pair of engaging holes 22a are formed to engage with the concave and convex portions. A guide surface 11a is formed at the front end of the assembly claw 11 such that the guide surface 11a is inclined so that the amount of protrusion from the body 10 decreases toward the front. Therefore, when assembling the cover 20 to the body 10, the assembly piece 22 bends along the guide surface 11a,
Finally, the engaging hole 22a provided in the assembly piece 22 is
The body 10 and the cover 20 are connected to each other. As described above, since the assembly piece 22 needs to be bent, the cover 20 is formed of an elastic synthetic resin.

Here, when the assembly piece 22 is molded, a plurality of resin flows are formed and merge near the tip of the assembly piece 22, so that a weld line is easily formed at the tip of the assembly piece 22. As described above, since the assembly piece 22 engages with the assembly claw 11 using the bending as described above, there is a problem that the weld line is easily broken at the time of bending if a weld line is formed. In view of this, a portion where the weld line is formed is formed with a reinforcing portion 22b having a partially increased thickness to prevent the assembly piece 22 from breaking.

The internal space of the body 10 is divided into two by a partition wall 12 provided at an intermediate portion in the longitudinal direction. Partition wall 12
Has a front end protruding forward from the opening surface of the body 10. Positioning projections 10a projecting forward are provided at appropriate places on the peripheral wall of the body 10. The partition wall 12 and the positioning projection 10a engage with a concave portion (not shown) formed in the cover 20 when the body 10 and the cover 20 are connected to each other, thereby preventing the cover 20 from rattling with the body 10. I do. In addition, a partition wall (not shown) is formed in the cover 20. When the body 10 and the cover 20 are connected, the body 1
The inner space of the housing 1 is divided into two independent chambers by abutting the partition wall 12 of the zero and the partition wall of the cover 20.

In each of the storage chambers 13 formed in the body 10 through the partition wall 12, a blade receiving member 30 is stored. Each blade receiving member 30 includes a pair of spring pieces 31 opposed to each other, a spring piece 32 opposed to one side surface of both spring pieces 31, and a U-shaped connecting piece for connecting the spring pieces 31 and 32 continuously and integrally. 33. In addition, a positioning piece 34 is provided on a side of each spring piece 31 and between the spring piece 32 and the connecting piece 33 so as to be continuously and integrally formed. Further, at the open end of the connecting piece 33, a terminal piece 35 is formed continuously and integrally with the connecting piece 33 so as to protrude in a direction away from each other. By the way, the blade receiving member 30 is formed such that the interval between the portions of the pair of spring pieces 31 opposed to each other that comes into contact with the pin-type blade becomes closer to the side closer to the spring piece 32 (see FIG. 5). In other words, the distance between the spring pieces 31 is increased on the side closer to each other in the double-blade receiving member 30. Therefore, when the pin-type blade is inserted into the blade receiving member 30, even if the distance between the pair of pin-type blades and the diameter of the pin-type blade differ depending on the type of plug, the spring piece 31 can be used. A force in the direction of positioning the plug near the center of the double-blade receiving member 30 is applied by the spring force, and the spring force of the spring piece 31 at the double-blade receiving member 30 can be equalized.

In the body 10, the positioning ribs 1 contacting the connecting piece 33, the positioning piece 34 and the terminal piece 35, respectively.
4a to 14d are formed and positioning ribs 14a to 14d
Accordingly, the blade receiving member 30 is positioned at a fixed position in the body 10. The positioning ribs 14c and 14d are formed so as to be opposed to each other, and a locking spring 36 is arranged between the terminal piece 35 contacting the positioning rib 14d and the positioning rib 14c. The locking spring 36 is formed by bending one end of the band plate into a J-shape to form a contact piece 36a and bending the other end into an S-shape to form a locking piece 36b. The contact piece 36a and the lock piece 36b are housed in the body 10 so as to face the terminal piece 35. The positioning piece 34, the terminal piece 35, and the locking spring 36 of the blade receiving member 30 are pressed by the holding ribs 23a, 23b provided in the cover 20 so as not to float from the body 10.

An electric wire insertion port 15 is formed in the rear wall of the body 10 so that an electric wire can be introduced between the locking spring 36 and the terminal piece 35. A lock piece 36a is inserted between the lock spring 36 and the terminal piece 35 through the wire insertion port 15.
When the electric wire is inserted from the side, the contact piece 36a and the lock piece 3
The wire is pinched between the terminal piece 35 and the locking piece 36b by the spring force of 6a, and the wire cannot be pulled out because the lock piece 36b bites into the wire. As described above, since the connection can be performed simply by inserting the electric wire into the electric wire insertion port 15, the connection operation is facilitated as compared with the case where a screw terminal or the like is used.

A release button 37 is provided in each storage chamber 13 so as to straddle a pair of locking springs 36 respectively facing a pair of terminal plates 35 provided on each blade receiving member 30. Release button 3
7 abuts against the lock pieces 36b of the both lock springs 36, and the body 1
0 so as to be slidable along the rear wall. The part where the release button 37 abuts on the lock piece 36b is shifted from the part where the lock piece 36b sandwiches the electric wire between the lock piece 36b and the terminal piece 35. An operation hole 16 is formed in the rear wall of the body 10 at a position corresponding to the release button 37, and by inserting the tip of a flathead screwdriver or the like into the operation hole 16 and pressing the release button 37, the wire is cut into the electric wire. The lock piece 36b is bent so as to be separated from the electric wire so that the electric wire can be pulled out. Here, a single wire having an insulating coating is generally used as the electric wire, and the length of the insulating coating is important for obtaining a required connection strength against pulling out of the electric wire. The rear surface is provided with a groove-shaped gauge 10b indicating a length for exposing the core wire. At the time of construction, the insulating coating is stripped so as to expose the core wire corresponding to the length of the gauge 10b.

As is clear from the above description, two electric wires can be connected to the blade receiving member 30 disposed in each of the storage chambers 13, respectively.
If the other electric wire is used as a feed wiring for connecting to another outlet, a connection operation for connecting a plurality of outlets in parallel becomes easy. In addition, since the electric wire on the power supply side and the electric wire serving as the feed wiring are individually connected, they are connected to the outlet that should be disconnected without disconnecting the two electric wires at the same time when disconnecting the already connected outlet. Since only the electric wires need to be replaced, it is possible to easily cope with a change in wiring.

On the front wall of the cover 20, there is formed a single insertion portion 24 into which a pair of blades provided for one plug can be inserted. The insertion portion 24 includes insertion ports 25 opened at portions corresponding to the spring pieces 31 and 32 of each blade receiving member 30, and each insertion port 25 has a flat-type plug blade into which a flat-type flat plug blade is inserted. The opening 25a is formed in a shape in which a pin-shaped blade insertion hole 25b into which a pin-shaped pin-shaped blade is inserted communicates. That is, the flat blade insertion port 25a has a rectangular shape, and has a shape in which a circular pin-type blade insertion port 25b communicates with one side edge of the intermediate portion in the longitudinal direction. Further, the distance between the centers of the pin-type blade insertion ports 25b is larger than the distance between the centers of the flat-type blade insertion ports 25a. The flat blade inserted into the flat blade insertion port 25a is sandwiched between the side surface of the spring piece 31 and the spring piece 32, and the pin-type blade inserted into the pin-type blade insertion port 25b is a pair. It is held between the spring pieces 31. The length of the flat blade insertion slot 25a is different between the voltage line side and the ground line side.
