Assembly holes 10b functioning as places are formed. On the other hand, two assembly protrusions 20a functioning as assembly protrusions that engage with the assembly holes 10b provided in the assembly piece 10a are projected on both upper and lower side surfaces of the cover 20 each. The rear surface of the assembly protrusion 20a is an inclined surface. When the assembly piece 10a and the assembly protrusion 20a are aligned and the body 10 and the cover 20 are pressed against each other, the assembly protrusion 10a is pushed and the assembly piece 10a is bent. The assembly protrusion 20a is inserted into the assembly hole 10b. As described above, the body 10 and the cover 20 can be coupled by a simple operation of pressing the body 10 and the cover 20 together at the time of assembly.

  The interior of the body 10 is partitioned into three chambers by a partition wall 11. That is, in the body 10, a grounding electrode section 12 a provided in the center portion and two voltage electrode sections 12 b and 12 c provided over substantially the entire length in the longitudinal direction on both sides in the width direction of the body 10. And are provided. A ground electrode member 13 is stored in the ground electrode section 12a, and voltage electrode members 14 and 14 are stored in the voltage electrode sections 12b and 12c.

  The grounding electrode member 13 connects a blade receiving spring 13a that receives a flat plug blade formed in a strip shape, and an external electric wire introduced from the blade receiving spring 13a and an electric wire insertion port 15 that opens in the rear wall of the body 10. The terminal 13b is integrally coupled with the caulking pin, and is accommodated in the ground electrode section 12a so that the flat plug blade is received at the center in the width direction of the body 10. The voltage electrode member 14 housed in the ground electrode section 12b connects a blade receiving spring 14a that receives a flat plug blade and an external electric wire introduced from an electric wire insertion port 15 that opens in the rear wall of the body 10. The voltage electrode member 14 housed in the grounding electrode section 12c is integrally formed with a blade receiving spring 14a for receiving a flat plug blade and a conductive plate 51 to be described later. The terminal 14c is also accommodated in the ground electrode section 12b. The blade receiving springs 14a and 14b are housed in the voltage electrode sections 12b and 12c, respectively, so as to be positioned at the lower part of FIG.

  Since the blade receiving springs 13a, 14a and 14b receive flat plug blades, two spring pieces made of leaf springs are arranged to face each other, and the flat plug blade is sandwiched between the two spring pieces. The blade receiving springs 13a, 14a, and 14b will be described later.

  The terminals 13b, 14c, and 14c are quick connection terminals that lock the external electric wires introduced into the body 1 through the electric wire insertion port 15 by using the spring force of the leaf springs. Two U-shaped locking pieces 16b are extended from one side edge in the width direction and pressed so as to face the leg pieces on the distal end side of each locking piece 16b from the other side edge in the width direction of the base piece 16a. It has a configuration in which two pieces 16c are extended. The leg piece on the distal end side of the locking piece 16b is located between the leg piece on the base piece 16a side of the locking piece 16b and the pressing piece 16c. The terminals 13b, 14c, and 14c are arranged such that an external electric wire introduced through the electric wire insertion port 15 is introduced between the locking piece 16b and the holding piece 16c from the distal end side of the holding piece 16c. The distal end portion of the locking piece 16b is inclined closer to the pressing piece 16c as the portion is closer to the distal end, and the holding piece 16c has a locking piece at an intermediate portion between the distal end of the locking piece 16b and the wire insertion port 15.

When the rear portion of the body 10 is inserted into the mounting opening 31, the rear surface of the holding projection piece 18 provided on the body 10 comes into contact with the front surface of the locking receiving piece 36, and the rearward movement is restricted. Further, when the holding convex portion 26 presses the locking pressing piece 35, the locking pressing piece 35 is bent outward, and when the holding convex portion 26 gets over the locking pressing piece 35, the rear surface of the locking pressing piece 35 is formed. When the front surface of the holding convex portion 26 comes into contact with a certain locking surface, the forward movement of the body 1 is restricted. That is, in a state where the container body 1 is coupled to the plate body 30, the body 10 and the cover 20 of the container body 1 are sandwiched between the locking receiving piece 36 and the locking pressing piece 35 of the plate body 30. Therefore, even if the assembly protrusion 20a is detached from the assembly hole 10b provided in the assembly piece 10a for some reason (such as heat shrinkage or damage of the material), the body 10 and the cover 20 are not detached. As a result, the range of selection of materials for the body 10 and the cover 20 is expanded.

  By the way, as shown in FIG. 2, positioning protrusions 37 are provided in the vicinity of the left and right mounting holes 32 a on the inner surface of the mounting opening 31 provided in the plate body 30. In other words, the latch receiving piece 36 is not formed at a position adjacent to the upper and lower portions of the positioning projection 37, and a recess is formed between the positioning projection 37 and the upper and lower latch receiving pieces 36. On the other hand, as shown in FIG. 2, positioning grooves 29 that engage with the positioning protrusions 37 are formed on the left and right side surfaces of the cover 20. The positioning groove 29 is formed at the center position in the vertical direction of the container 1. That is, the positioning projection 37 and the positioning groove 29 are formed at symmetrical positions in the vertical direction within the opening surface of the mounting opening 31 in a state where the container body 1 is mounted on the plate body 30.

  By the way, the blade receiving springs 14a and 14b arranged corresponding to the two insertion ports 21b and 21c arranged in parallel in the prescribed direction are a pair of spring pieces and springs that face each other and sandwich the flat plug blade. The blade receiving spring 14b arranged on the right side is connected to the support piece 61 arranged on the rear surface of the connecting piece. It is connected by a caulking rod 71 so as to be rotatable in a plane orthogonal to the thickness direction. The support piece 61 is constituted by a part of the conductive plate 51 described above, and an insertion hole 62 through which the caulking rod 71 is inserted is formed.

  Here, the blade receiving spring 14b is arranged in the body 10 as shown in FIGS. 1 (a) and 1 (b), but before being incorporated in the body 10, it is in a plane perpendicular to the thickness direction of the connecting piece. When the connecting piece is rotated 180 degrees, the shape of the pair of spring pieces is formed asymmetrically so that the distance between the front end of the pair of spring pieces and the other blade receiving spring 14a changes (in the longitudinal direction of the connecting piece). It is formed asymmetrically with respect to a plane that is orthogonal and bisects the connecting piece). Accordingly, by rotating the connecting piece obtained by continuously and integrally connecting the rear end edges of the pair of spring pieces in the blade receiving spring 14b within a plane orthogonal to the thickness direction, the front end portion of the pair of spring pieces and the other end of the pair of spring pieces are rotated. The distance from the blade receiving spring 14a can be changed as shown in FIGS. 1 (c) and 1 (d). 2 to 4, the blade socket spring 14b is housed in the body 10 as shown in FIGS. 1 (a) and 1 (b). 1B, the blade receiving spring 14b is housed as shown in FIGS. 1 (c) and 1 (d). The latter is the front end of the pair of spring pieces and the other blade. The space | interval with the receiving spring 14a is large. Therefore, in this embodiment, it is possible to share the blade receiving spring 14b with other outlets having different intervals between the insertion ports 21b and 21c in the specified direction according to the difference in rating, and the components of the blade receiving spring 14b. Costs can be reduced and costs can be reduced. In the present embodiment, the interval is changed by rotating one blade receiving spring 14b of the blade receiving springs 14a and 14b arranged in parallel in the specified direction by 180 degrees. What is necessary is just to comprise so that at least one of the blade receiving springs 14a and 14b provided can be rotated 180 degree | times.

  The blade receiving spring 13a described above has a connection piece 13c that is connected to the front surface of the base piece 16a of the terminal 13b, and is provided with an extending piece 13d that extends forward from both end edges of the connection piece 13c. Therefore, in order to prevent the blade receiving spring 13a from being lifted from the body 10, the protruding dimension of the holding rib 25b protruding from the inner bottom surface of the cover 20 toward the body 10 can be reduced as compared with the conventional case. That is, in this embodiment, the holding ribs 25b that prevent the blade receiving springs 13c from lifting up may be brought into contact with the distal end surfaces of the extending pieces 13d. The projecting dimension can be reduced, and the strength of the holding rib 25b can be easily secured.

(Embodiment 2)
The basic configuration of the outlet of this embodiment shown in FIGS. 7 and 8 is substantially the same as the outlet with a switch of FIGS. 2 to 4 described in the first embodiment. The difference is that 14b is connected to the terminal 14c via a conductive plate having a support piece similar to that of the first embodiment.

Further, in this embodiment, instead of providing the handle platform 19c described in the first embodiment, the upper portion of the right side surface of the body 10 is positioned more rightward than the right side surface of the cover 20 when coupled to the cover 20. One cover piece 19a is projected, and a second cover piece 19b is projected forward near the base of the first cover piece 19a. The first and second cover pieces 19a, 19b are Since the switch 20 is engaged with the switch mounting notch 28 of the cover 20, the switch mounting notch 28 is closed when the cover 20 is coupled to the body 10. Other configurations are the same as those of the first embodiment.
(Embodiment 3)
The basic configuration of the outlet of the present embodiment shown in FIG. 9 is substantially the same as that of the second embodiment, and is different in that one outlet has two outlets having different shapes. That is, one outlet port is configured by the insertion ports 21a, 21b, and 21c similarly to the second embodiment, and the other outlet port is configured by the two insertion ports 22b and 22b. Further, in the body 10, blade receiving springs 14e and 14e are housed in portions corresponding to the insertion ports 22b and 22b.
The insertion port 22b has a shape into which both a round pin and a flat plug blade can be inserted, and the opening surface is formed in a semicircular shape or a semi-elliptical shape. The insertion ports 22b are arranged side by side in the left-right direction (the same direction as the specified direction), and the closest part of both insertion ports 22b is formed in a straight line in the vertical direction, and is flat along the straight line part. The blade is inserted. The part for inserting the flat plug blade is formed wider than the part for inserting the round pin. Thus, the outlet of the present embodiment is provided with an outlet port composed of the insertion ports 22b and 22b and an outlet port composed of the insertion ports 21a, 21b and 2c.

  As shown in FIG. 10, the blade receiving spring 14e is capable of receiving both a flat plug blade and a round pin, and a portion for holding the round pin is a shape in which two spring pieces 142 and 142 are opposed to each other. The flat spring plug is provided between the side surfaces of the two spring pieces 142 and 142 and the one spring piece 141 by making one spring piece 141 face one side surface of both spring pieces 142 and 142. The structure which holds a blade is adopted. 11 is a development view of the blade receiving spring 14e formed of a metal member. A spring piece 141 is extended from the upper edge (front edge) of the central portion of the base portion 140 shown in FIG. Spring pieces 142 are extended from the upper edges of the respective portions, and lead pieces connectable by caulking and fixing to coupling pieces 16d extending from both side edges of the base portion 140 to the side edges of the locking pieces 16b of the terminals 14c. 143 is extended.

  Further, in the present embodiment, the support piece 61 is configured in which the other end portions of the lead plates 14f and 14g whose one end portions are connected to the terminals 14c and 14c are arranged so as to overlap the rear surfaces of the connecting pieces of the blade receiving springs 14a and 14b. The connecting pieces of the blade receiving springs 14a and 14b are rotatably coupled to the support pieces 61 and 61 by caulking hooks.

  Further, the blade receiving springs 14e and 14e arranged in parallel in the specified direction at the upper part of the body 10 are provided with a continuous lead plate 143 connected to the terminals 14c and 14c, and the specified direction is the left-right direction. Since it is sometimes formed in a symmetrical shape, the cost can be reduced by reducing the number of parts, and the assembling work is facilitated as compared with the case where the lead plate and the blade receiving spring are caulked and fixed.
