Description

This disclosure relates generally to power strips, and more specifically to power strips having a receptacle to which a conductor of an insertion plug is connected.

The table tap described in Patent Document 1 comprises a housing (casing), a blade receiving member (receiving portion), a conductive plate (lead portion), and a power cord (electric wire). The housing houses the blade receiving member and the conductive plate. The housing has an electrode insertion port and a wire hole. The blade receiving member is electrically connected to the plug blade (electrode) of the plug inserted into the electrode insertion port of the housing. The conductive plate is connected to the blade receiving member. One end of the electric wire cord is connected to the conductive plate, and the other end of the electric wire cord is pulled out from the inside of the housing to the outside through the wire hole of the housing.

The device is divided into a body and a cover so as to diametrically divide the electric wire hole in two. Therefore, the tip surface of the peripheral wall of the body (i.e., the connecting surface with the cover) is provided with a concave groove that constitutes one side of the divided electric wire hole. The tip surface of the peripheral wall of the cover (i.e., the connecting surface with the body) is provided with a concave groove that constitutes the other side of the divided electric wire hole.

JP 2012-174503 A

As described above, in the table tap described in Patent Document 1, a groove is provided on the tip surface of the peripheral wall of the body. This groove penetrates the peripheral wall of the body in the thickness direction and is open at the tip surface of the peripheral wall of the body. Therefore, this groove is a factor that reduces the rigidity and strength of the body. Similarly, the above-mentioned groove provided in the cover is also a factor that reduces the rigidity and strength of the cover.

In view of the above, the present disclosure aims to provide a table tap with a housing that has holes for electrical wires and that prevents a decrease in the rigidity and strength of the cover and body that constitute the housing.

A power strip according to an aspect of the present disclosure includes a cover, a power cable, and a body. The cover is provided with a plurality of pairs of plug holes. The power cable receives power from the external power source. The body is provided with a wire hole through which the power cable passes. The body has two vertical ribs disposed on an inner circumferential surface of the body on both sides of the wire hole and protruding perpendicularly from the inner circumferential surface into the body. An outer circumferential portion of the cover fits inside an opening of the body.

Below, a table tap according to one embodiment of the present disclosure will be specifically described with reference to the drawings. Note that the configuration described below is merely one example of the present disclosure, and the present disclosure is not limited to the following embodiment. Therefore, even if it is an embodiment other than this, various modifications can be made according to the design, etc., as long as they do not deviate from the technical idea of the present disclosure.

In the following description, unless otherwise specified, the "up", "down", "left", "right", "front", and "rear" directions are defined as indicated by the arrows "up", "down", "left", "right", "front", and "rear" in Figures 1 to 10. Therefore, in this embodiment, the longitudinal direction of the housing 3 is the front-rear direction, the transverse direction (width direction) of the housing 3 is the left-right direction, and the thickness direction of the housing 3 is the up-down direction. However, these directions are not intended to limit the direction in which the table tap 1 can be used. Also, the arrows indicating the directions in the drawings are merely shown for explanatory purposes and do not have any substance.

(overview)
With reference to FIG. 1, an overview of the table tap 1 of the present embodiment (mainly the external appearance) will be described. As shown in FIG. 1, the table tap 1 is a device into which an attachment plug 200 can be inserted and which supplies power to the inserted attachment plug 200. The table tap 1 has three sockets 2 (also called outlets). One attachment plug 200 can be inserted into each of the three sockets 2. That is, the table tap 1 can simultaneously insert up to three attachment plugs 200. Note that the number of sockets 2 (i.e., the number of attachment plugs 200 that can be simultaneously inserted into the table tap 1) is not limited to three. The attachment plug 200 is connected to an end of an electric wire 201 drawn from, for example, an electric device. The attachment plug 200 has a plurality of conductors 202 (a pair of electrodes 202a, 202b and one ground terminal 202c).

The table tap 1 includes a housing 3. The housing 3 is an outer shell that houses various components 8 (see FIG. 2) of the table tap 1. The housing 3 is, for example, a box-like shape that is a substantially rectangular parallelepiped extending in the front-rear direction, and has an upper surface 31, a lower surface 32, a left side surface 33, a right side surface 34, a front side surface 35, and a rear side surface 36. In this embodiment, the upper surface 31 and the lower surface 32 are, for example, oval shapes extending in the front-rear direction. The left side surface 33 and the right side surface 34 are substantially rectangular shapes extending in the front-rear direction. The front side surface 35 is a semi-cylindrical shape (i.e., a shape of a cylinder cut in half vertically) that is convex forward. The rear side surface 36 is a semi-cylindrical shape that is convex backward. The lower surface 32 is, for example, formed one size smaller than the upper surface 31. Accordingly, the left side surface 33, the right side surface 34, the front side surface 35, and the rear side surface 36 are inclined toward the inside of the housing 3 from the upper surface 31 side toward the lower surface 32 side.

A wire hole 4 is provided on the front side surface 35. A power cable 5 connected to an external power source is pulled from the outside of the housing 3 to the inside through this wire hole 4. The power cable 5 pulled into the inside of the housing 3 is connected to electrical components among the various components 8 (see FIG. 2) housed in the housing 3.

A cylindrical bushing member B1 is provided between the electric wire hole 4 and the power cable 5. That is, the bushing member B1 is inserted into the electric wire hole 4, and the power cable 5 is passed through this bushing member B1. One end of the bushing member B1 is exposed to the outside of the housing 3, and the other end of the bushing member B1 is inserted into the housing 3. The outer diameter of the bushing member B1 increases from one end to the other end. The other end of the bushing member B1 is provided with a flange portion B1a that protrudes on the outer periphery (see Figure 2). This bushing member B1 is not necessary.

The top surface 31 is provided with three outlets 2 and a cutoff switch 6. That is, the housing 3 has three outlets 2. The three outlets 2 are lined up in one direction (for example, the longitudinal direction of the top surface 31). Each of the three outlets 2 has a set of plug holes 21. This set of plug holes 21 (i.e., one outlet 2) corresponds to one plug 200. The set of plug holes 21 has three plug holes 21a, 21b, 21c (i.e., a pair of plug holes 21a, 21b and one plug hole 21c). Three conductors 202 (i.e., a pair of electrodes 202a, 202b and one ground terminal 202c) of one plug 200 are inserted into the set of three plug holes 21a, 21b, 21c. The number of insertion holes 21 in one set is not limited to three, and can be determined according to the number of conductors 202 in one insertion plug 200.

Of the set of three plug holes 21a, 21b, 21c, the pair of plug holes 21a, 21b (first plug holes) are plug holes into which the pair of electrodes 202a, 202b of the plug plug 200 are inserted, and are aligned along the longitudinal direction of the top surface 31. Therefore, the direction in which the pair of plug holes 21a, 21b are aligned coincides with the direction in which the three sockets 2 are aligned. The remaining plug hole 21c (second plug hole) is a plug hole into which the ground terminal 202c of the plug plug 200 is inserted, and is located on one side of the pair of plug holes 21a, 21b in the left-right direction (e.g., the left side).

In this table tap 1, the three conductors 202 (202a, 202b, 202c) of the plug 200 are inserted into a set of three sockets 21a, 21b, 21c, so that the table tap 1 and the plug 200 are electrically connected to each other. As a result, power is supplied from the table tap 1 to the plug 200.

The cutoff switch 6 is a switch for manually switching between supplying and stopping power from the table tap 1 to the plug 200 inserted into the table tap 1. When the cutoff switch 6 is on, power is supplied from the table tap 1 to the plug 200 inserted into the table tap 1. When the cutoff switch 6 is off, the power supply from the table tap 1 to the plug 200 inserted into the table tap 1 is stopped.

The cutoff switch 6 has an overcurrent cutoff function. That is, the cutoff switch 6 can be manually switched on or off when a current less than a predetermined current value flows through the electrical components inside the table tap 1. On the other hand, the cutoff switch 6 automatically switches from on to off when a current equal to or greater than a predetermined current value (i.e., an overcurrent) flows through the electrical components inside the table tap 1. This makes it possible to prevent, for example, when an overcurrent flows through the power cable 5, the overcurrent from flowing through the plug 200 inserted into the table tap 1.

The upper surface 31 is divided into a first region 37 and a second region 38. The first region 37 is the range from the rear end of the upper surface 31 to the center front of the length of the upper surface 31 in the longitudinal direction (i.e., the front-to-rear direction) (e.g., the range of the rear two-thirds of the upper surface 31). The second region 38 is the range from the front end of the upper surface 31 to the center front of the length of the upper surface 31 in the longitudinal direction (e.g., the range of the front one-third of the upper surface 31). The first region 37 is one step higher than the second region 38.

The multiple (three) outlets 2 (i.e., multiple sets (three sets) of plug holes 21) are arranged in the longitudinal direction (i.e., the front-to-rear direction) of the top surface 31. In this embodiment, the multiple outlets 2 are arranged, for example, in a first region 37 of the top surface 31. The cutoff switch 6 is arranged, for example, in a second region 38 of the top surface 31.

In this way, power is input from an external power source to the table tap 1 via the power cable 5. When the plug 200 is inserted into the outlet 2 of the table tap 1, the plug 200 and the table tap 1 are electrically connected. When the cutoff switch 6 is on, power is supplied from the table tap 1 to the plug 200 by inserting the plug 200 into the outlet 2 of the table tap 1. During this power supply, if the cutoff switch 6 is manually switched from on to off, the power supply from the table tap 1 to the plug 200 is stopped. Also, if an overcurrent flows through the table tap 1, the cutoff switch 6 is automatically switched from on to off, and the power supply from the table tap 1 to the plug 200 is stopped.

(Detailed explanation)
Next, the configuration of the power strip 1 will be described with reference to FIGS.

As shown in FIG. 2, the table tap 1 includes a housing 3 and various components 8 housed in the housing 3. The housing 3 includes a body 40 and a cover 50. The body 40 is box-shaped (e.g., deep-bottomed box-shaped) with an internal space 40f that houses the various components 8, and has an opening 40a connected to the internal space 40f. The cover 50 is a member that closes the opening 40a of the body 40, and is, for example, plate-shaped. The various components 8 include a pair of electrode members 10A, 10B, a conductive member 12 for earthing, multiple outlet blocks 13, and a cutoff switch 6.

(Body 40)
The body 40 will be described with reference to Figures 2 and 3. The body 40 is made of a thermoplastic resin such as PCABS resin. As shown in Figure 2, the body 40 is a box-like shape that is substantially rectangular and extends in the front-rear direction, and has an opening 40a on the top surface. The body 40 has a bottom wall 41, a left side wall 42, a right side wall 43, a front side wall 44, and a rear side wall 45.

The outer surfaces (i.e., outer main surfaces) of the bottom wall 41, the left side wall 42, the right side wall 43, the front side wall 44, and the rear side wall 45 form the bottom surface 32, the left side surface 33, the right side surface 34, the front side surface 35, and the rear side surface 36 of the housing 3. The left side wall 42, the right side wall 43, the front side wall 44, and the rear side wall 45 form the peripheral wall portion 46 of the body 40. The inner surfaces (i.e., inner main surfaces) of the left side wall 42, the right side wall 43, the front side wall 44, and the rear side wall 45 form the inner peripheral surface 46b of the peripheral wall portion 46. The upper ends of the left side wall 42, the right side wall 43, the front side wall 44, and the rear side wall 45 form the peripheral portion 40b of the opening 40a. The space surrounded by the bottom wall 41, the left side wall 42, the right side wall 43, the front side wall 44, and the rear side wall 45 is the internal space 40f.

The bottom wall 41 is a generally rectangular plate (e.g., an oval plate) that is long in the front-rear direction. The left side wall 42 and the right side wall 43 rise upward from both ends of the bottom wall 41 in the short direction (left-right direction). The front side wall 44 and the rear side wall 45 rise upward from both ends of the bottom wall 41 in the longitudinal direction (front-rear direction). The front side wall 44 is curved, for example, in a semi-cylindrical shape that is convex forward along the arc shape of the front end of the bottom wall 41. The rear side wall 45 is curved, for example, in a semi-cylindrical shape that is convex backward along the arc shape of the rear end of the bottom wall 41. The bottom wall 41 is formed, for example, one size smaller than the opening 40a on the upper surface. Accordingly, the left side wall 42, the right side wall 43, the front side wall 44, and the rear side wall 45 are inclined toward the inside of the body 40 from the opening 40a side toward the bottom wall 41 side.

The inner surface (top surface) of the bottom wall 41 has multiple (e.g., four) partitioned areas 15. The multiple partitioned areas 15 are lined up in the longitudinal direction (front-to-back direction) on the inner surface of the bottom wall 41. Of the multiple partitioned areas 15, a cutoff switch 6 is arranged in one of the partitioned areas 15 on the front side. The three partitioned areas 15 on the rear side correspond one-to-one to the three outlets 2 of the cover 50, and components (outlet block 13, pair of receptacles 70, receptacle 90, etc.) corresponding to the corresponding outlets 2 are arranged therein.

The front wall 44 of the body 40 is provided with an electric wire hole 4 through which the power cable 5 passes. The electric wire hole 4 is provided, for example, in the center of the front wall 44 and penetrates the front wall 44 in the thickness direction. The outline of the opening of the electric wire hole 4 is, for example, circular. The entire periphery of the outline of the opening of the electric wire hole 4 is closed. Because the entire periphery of the electric wire hole is closed, even if the electric wire hole is provided in the body, it is possible to prevent the strength and rigidity of the body from being reduced by the electric wire hole.

2 and 3, the peripheral portion 40b of the body 40 has an outer peripheral portion 40c and an inner peripheral portion 40d. The outer peripheral portion 40c is the outer half of the peripheral portion 40b in the width direction, and the inner peripheral portion 40d is the inner half of the peripheral portion 40b in the width direction. The inner peripheral portion 40d is one step lower than the outer peripheral portion 40c. As a result, a step portion 40e is formed between the outer peripheral portion 40c and the inner peripheral portion 40d. When the opening 40a of the body 40 is closed by the cover 50, the outer wall portion 51 of the cover 50 described later is caught by the inner peripheral portion 40d. As a result, the position of the cover 50 in the depth direction of the body 40 is positioned at the position of the opening surface of the opening 40a. Furthermore, the outer wall portion 51 of the cover 50 described later comes into contact with the step portion 40e, and the cover 50 is positioned at a predetermined position on the opening surface of the opening 40a.

As shown in FIG. 2, the body 40 is provided with a plurality of vertical ribs 60, a first clamping wall portion 61, a plurality of boss portions 62, and a plurality of protrusion portions 63.

The multiple (eight, for example) vertical ribs 60 are portions that reinforce the rigidity and strength of the body 40. The multiple vertical ribs 60 are provided on the inner peripheral surface 46b of the body 40. The multiple vertical ribs 60 are arranged at intervals from each other in the circumferential direction of the inner peripheral surface 46b of the body 40. In this embodiment, three vertical ribs 60 are provided on the inner surface of the left side wall 42, three on the inner surface of the right side wall 43, and two on the inner surface of the front side wall 44. The three vertical ribs 60 on each of the left side wall 42 and the right side wall 43 are arranged, for example, along the boundary of the partition area 15 of the bottom wall 41. The two vertical ribs 60 on the front side wall 44 are arranged on both the left and right sides of the electric wire hole 4. Each vertical rib 60 is formed in a flat plate shape and protrudes vertically from the inner peripheral surface 46b of the body 40 into the inside of the body 40. Each vertical rib 60 extends from the peripheral edge portion 40b of the body 40 to the bottom along the depth direction of the body 40.

The first clamping wall 61 is a member that clamps the power cable 5, which is pulled from the outside of the body 40 to the inside through the wire hole 4 of the body 40, between the first clamping wall 61 and the second clamping wall 53 of the cover 50, which will be described later. In this embodiment, the first clamping wall 61 and the second clamping wall 53 form a clamping section 17 that clamps the power cable 5 that has passed through the wire hole 4. That is, the housing 3 has a clamping section 17 that clamps the power cable 5 that has passed through the wire hole 4 in the internal space 40f. By clamping the power cable 5 with the clamping section 17 in this way, even if the power cable 5 is pulled outside the housing 3, the tension at that time can be stopped by the clamping section 17. As a result, even if the power cable 5 is pulled, the connection between the various components 8 in the housing 3 and the power cable 5 can be prevented from being cut. Hereinafter, this effect will also be referred to as tension stop.

The first clamping wall portion 61 is provided on the bottom wall 41 of the body 40 on the back side of the wire hole 4 of the body 40 (i.e., the back side of the front wall 44). The first clamping wall portion 61 is provided in a wall shape so as to rise from the bottom wall 41 of the body 40. The height of the first clamping wall portion 61 is the height between the lower end 4a and the upper end 4b of the opening of the wire hole 4 (see FIG. 10). The first clamping wall portion 61 is provided so as to intersect (e.g., perpendicular to) the wiring path along which the power cable 5 is wired (i.e., extending in the width direction (left-right direction) of the bottom wall 41).

The first clamping wall 61 has a plurality of (e.g., two) first walls 61a. Each of the first walls 61a intersects (e.g., perpendicular to) the routing path of the power cable 5 and is arranged at intervals in the thickness direction. By configuring the first clamping wall 61 with a plurality of first walls 61a, the frictional resistance between the first clamping wall 61 and the power cable 5 can be increased. As a result, the effect of the tension stop described above can be improved. In addition, the pressure acting on the power cable 5 from the first clamping wall 61 can be dispersed, reducing the burden on the power cable 5.

The multiple (e.g., four) boss portions 62 are fastened to the boss portion 54 of the cover 50 described later to fix the body 40 and the cover 50 to each other. The multiple boss portions 62 are provided on the bottom wall 41 of the body 40 so as to protrude from the bottom wall 41 of the body 40 into the inside of the body 40. The multiple boss portions 62 are provided so as to be distributed throughout the bottom wall 41. For example, of the four boss portions 62, two boss portions 62 are disposed in the center of two boundaries that divide the three rear partition areas 15 of the four partition areas 15 of the bottom wall 41. The remaining two boss portions 62a (62) (first boss portions) are provided at both ends of the first clamping wall portion 61 (i.e., at both sides in the width direction (left-right direction) of the first clamping wall portion 61) and are formed integrally with both ends of the first clamping wall portion 61. In this way, the two bosses 62a and both ends of the first clamping wall 61 are integrally formed, which improves the strength of the first clamping wall 61 and further improves the above-mentioned tension stop effect. Note that the boss 62a may be provided on only one of the ends of the first clamping wall 61.

Each of the bosses 62 has a through hole 62b. The through hole 62b is a through hole through which the screw N1 passes. The screw N1 is a screw for fixing the body 40 and the cover 50 to each other. The through hole 62b is provided along the central axis direction (up and down direction) of the boss 62. The through hole 62b passes through the boss 62 and the bottom wall 41 of the body 40, connecting the inside and outside of the body 40.

The multiple (e.g., nine) protrusions 63 are parts that press the underside of the outlet block 13 when the cover 50 closes the opening 40a of the body 40, and position the outlet block 13 in the vertical direction within the body 40. Each protrusion 63 is provided, for example, in a cylindrical shape so as to protrude from the inner surface of the bottom wall 41. The multiple (nine) protrusions 63 are arranged in multiples (e.g., three each) in each of the three rear compartment areas 15 (i.e., the compartment areas in which the outlet block 13 is arranged) of the four compartment areas 15 of the bottom wall 41.

The vertical ribs 60 will be described with reference to FIG. 3. As shown in FIG. 3, the upper end 60a of each vertical rib 60 is formed at a height between the outer peripheral edge 40c and the inner peripheral edge 40d of the peripheral edge 40b of the body 40. The upper end 60a of each vertical rib 60 is provided with a recess 60b into which the outer wall 51 of the cover 50 described later fits. The bottom of the recess 60b is flat and connected to the inner peripheral edge 40d of the body 40. As a result, when the cover 50 closes the opening 40a of the body 40, the lower end of the outer wall 51 of the cover 50 described later comes into contact with the bottom of the recess 60b of the vertical rib 60. As a result, the position of the cover 50 in the depth direction of the body 40 is positioned at the position of the opening surface of the opening 40a. Furthermore, the outer wall 51 of the cover 50 described later comes into contact with the inner side surface of the recess 60b, so that the position of the cover 50 on the opening surface of the opening 40a is positioned at a predetermined position.

The upper portion G1 of the inner peripheral surface 46b of the body 40 is perpendicular to the bottom wall 41 of the body 40, but the lower portion G2 of the inner peripheral surface 46b of the body 40 is inclined toward the inside of the body 40 as the peripheral wall portion 46 of the body 40 is inclined toward the inside of the body 40. That is, the lower portion G2 of the inner peripheral surface 46b of the body 40 is inclined toward the inside of the body 40 toward the lower end of the inner peripheral surface 46b. Accordingly, the upper portion 60e of the vertical rib 60 extends perpendicular to the bottom wall 41, but the lower portion 60f of the vertical rib 60 is inclined toward the inside of the body 40 along the lower portion G2 of the inner peripheral surface 46b of the body 40. As a result, even if the lower portion G2 of the inner peripheral surface 46b of the body 40 is inclined toward the inside of the body 40, the width (i.e., the width in the left-right direction) of the lower portion 60f of the vertical rib 60 can be secured to a constant width, and the strength and rigidity of the vertical rib 60 can be secured.

(Cover 50)
The cover 50 will be described with reference to FIGS.

The cover 50 is formed of a thermoplastic resin such as polycarbonate resin. As shown in FIG. 2, the cover 50 is a generally rectangular (e.g., oval) plate extending in the front-rear direction. The outer surface (i.e., the outer main surface) of the cover 50 forms the upper surface 31 of the housing 3.

The cover 50 has approximately the same shape and size as the opening 40a of the body 40 (more specifically, the same shape and slightly smaller than the opening 40a). The outer periphery 50a of the cover 50 can be fitted inside the opening 40a of the body 40 (see FIG. 1). By fitting the outer periphery 50a of the cover 50 inside the opening 40a of the body 40, the opening 40a is closed by the cover 50. In this way, by fitting the outer periphery 50a of the cover 50 inside the opening 40a of the body 40, the outer periphery 50a of the cover 50 is protected by the body 40.

The cover 50 is provided with a plurality of outlets 2 and an exposure window 18 that exposes the cutoff switch 6. As described above, each of the plurality of outlets 2 has a set of plug holes 21 (i.e., three plug holes 21a, 21b, 21c). Thus, the cover 50 is provided with a plurality of sets (e.g., three sets) of plug holes 21. The plurality of sets of plug holes 21 and the exposure window 18 penetrate the cover 50 in the thickness direction. As described above, the plurality of sets of plug holes 21 (i.e., the plurality of outlets 2) are provided in the first region 37 of the outer surface of the cover 50 and are aligned along the longitudinal direction of the cover 50. The exposure window 18 is, for example, rectangular, and is provided in a predetermined region (e.g., the right half region) in the second region 38 of the outer surface of the cover 50.

As shown in FIG. 4, the rear surface 50b of the cover 50 is provided with an outer wall portion 51, an inner wall portion 52, a second clamping wall portion 53, a plurality of boss portions 54, a plurality of positioning portions 55, a plurality of temporary fixing portions 56, and a plurality of mounting walls 57.

The rear surface 50b of the cover 50 has a plurality of (e.g., four) partitioned areas 20. The plurality of partitioned areas 20 are arranged in the longitudinal direction on the rear surface 50b of the cover 50. Of the plurality of (e.g., four) partitioned areas 20, one of the front partitioned areas 20 is provided with an exposure window 18, in which a cutoff switch 6 is disposed. The three rear partitioned areas 20 correspond one-to-one to the three outlets 2 of the cover 50, and also correspond one-to-one to the three rear partitioned areas 15 of the four partitioned areas 15 of the bottom wall 41 of the body 40. Each of the three rear partitioned areas 20 is provided with a set of plug holes 21 (i.e., three plug holes 21a, 21b, 21c), in which a plug block 13 is disposed.

The second clamping wall 53 is a member for clamping the power cable 5 between itself and the first clamping wall 61 of the body 40. The power cable 5 is a power cable that is pulled from the outside to the inside of the body 40 through the wire hole 4 of the body 40.

The power cable 5 has multiple (e.g., three) electric wires 5a, 5b, and 5c and an outer casing 5d. Each of the electric wires 5a, 5b, and 5c is a coated electric wire. The outer casing 5d is a member that bundles and covers the electric wires 5a, 5b, and 5c. The electric wire 5a is electrically connected to the electrode member 10A, the electric wire 5b is electrically connected to the electrode member 10B, and the electric wire 5c is electrically connected to the conductive member 12. From the end of the outer casing 5d of the power cable 5, the electric wires 5a, 5b, and 5c inside the outer casing 5d are pulled out by the same length. That is, each of the electric wires 5a to 5c has a portion (pulled-out electric wire portion 5a1, 5b1, 5c1) pulled out by the same length from the outer casing 5d of the power cable 5.

The second clamping wall 53 is provided near the front end of the back surface 50b of the cover 50 (i.e., at a position set back a certain distance from the front end). The second clamping wall 53 is provided in the shape of a wall rising from the back surface 50b of the cover 50. The second clamping wall 53 is provided so as to intersect (e.g., perpendicular to) the routing path along which the power cable 5 is routed (in other words, along the width direction (left-right direction) of the cover 50).

The second clamping wall portion 53 is formed to a predetermined height. The predetermined height is, for example, a height at which the tip of the second clamping wall portion 53 is positioned between the upper end 4b and the lower end 4a of the opening of the electric wire hole 4 when the cover 50 closes the opening 40a of the body 40. In other words, the height of the second clamping wall portion 53 is a height at which the power cable 5 can be clamped with appropriate pressure between the first clamping wall portion 61 and the second clamping wall portion 53 when the cover 50 closes the opening 40a of the body 40.

The second clamping wall portion 53 has multiple (e.g., two) second walls 53a. Each second wall portion 53a intersects (e.g., perpendicular to) the routing path of the power cable 5 and is arranged at intervals in the thickness direction. By configuring the second clamping wall portion 53 with multiple second walls 53a, the frictional resistance between the second clamping wall portion 53 and the power cable 5 can be increased, and as a result, the above-mentioned tension stop effect can be improved. In addition, the pressure acting on the power cable 5 from the second clamping wall portion 53 can be dispersed, reducing the burden on the electric wire.

At both ends of the second clamping wall 53 (i.e., at both sides in the width direction (left and right direction) of the second clamping wall 53), bosses 54a (second bosses) are provided as described below. Both ends of the second clamping wall 53 and the bosses 54a are integrally formed. By integrally forming the two bosses 54a and both ends of the second clamping wall 53 in this manner, the strength of the second clamping wall 53 can be improved, and the above-mentioned tension stop effect can be further improved. The bosses 54a may be provided only at one end of both ends of the second clamping wall 53. The outer wall 51 and the inner wall 52 are parts that reinforce the rigidity and strength of the cover 50. The outer wall 51 and the inner wall 52 are provided so as to rise from the back surface 50b of the cover 50. The outer wall 51 is provided around the entire periphery (i.e., the entire circumferential direction) of the back surface 50b of the cover 50. The inner wall portion 52 is provided inside the outer wall portion 51 and spaced apart from the outer wall portion 51 along the circumferential direction of the cover 50.

Both ends of the inner wall portion 52 are integrally connected to both ends of the second clamping wall portion 53. That is, the second clamping wall portion 53 functions as part of the inner wall portion 52. Therefore, the inner wall portion 52, including the second clamping wall portion 53, is provided over the entire circumferential direction of the back surface 50b of the cover 50. The inner wall portion 52 and the second clamping wall portion 53 are the same height, but may be different heights.

In this way, the outer wall portion 51 and the inner wall portion 52 are formed around the entire circumference of the cover 50, thereby further improving the strength and rigidity of the cover 50.

The height of the inner wall portion 52 is higher than the height of the outer wall portion 51. This allows the outer wall portion 51 and the inner wall portion 52 to improve the strength and rigidity of the cover 50 without interfering with the inner circumferential surface 46b of the body 40 (i.e., the inner circumferential surface that slopes inward). Note that the height of the inner wall portion 52 is the height of the inner wall portion 52 relative to the back surface 50b of the cover 50, and the height of the outer wall portion 51 is the height of the inner wall portion 52 relative to the back surface 50b of the cover 50.

The multiple (e.g., four) boss portions 54 are fastened to the boss portion 62 of the body 40 to fix the body 40 and the cover 50 to each other. The multiple boss portions 54 are provided so as to protrude from the back surface 50b of the cover 50. The multiple boss portions 54 are provided so as to be distributed over the entire back surface 50b of the cover 50. For example, of the four boss portions 54, two boss portions 54 are disposed in the center of two boundaries that divide the three rear partition areas 20 of the four partition areas 20 on the back surface 50b of the cover. The remaining two boss portions 54a (54) are provided at both ends of the second clamping wall portion 53 (i.e., at both sides in the width direction (left and right direction) of the second clamping wall portion 53) and are formed integrally with both ends of the second clamping wall portion 53. In this way, the two bosses 54a and both ends of the second clamping wall 53 are integrally formed, which improves the strength of the second clamping wall 53 and further enhances the above-mentioned tension stop effect.

Each boss 54 has a bottomed screw hole 54b. The screw hole 54b is a hole into which the screw N1 is screwed. The screw N1 is a screw for fixing the body 40 and the cover 50 to each other. The screw hole 54b is provided along the central axis direction (up and down direction) of the boss 54.

The multiple (e.g., nine) positioning portions 55 are portions that position the outlet block 13 on the back surface 50b of the cover 50. The outlet block 13 is a member that holds the receiving portions 70A, 70B, and 90 described below.

The multiple (nine) positioning portions 55 are arranged in multiples (e.g., three) in each of the three rear partition areas 20 (i.e., the partition areas in which the outlet blocks 13 are arranged) of the four partition areas 20 on the back surface 50b of the cover 50. For example, in each partition area 20, the three positioning portions 55 are provided near three of the four corners of the partition area 20, one each.

Each positioning portion 55 has a tube portion (e.g., a cylindrical portion) 55a and a mounting wall portion 55b. The tube portion 55a is a portion that fits into a positioning hole 134 of the outlet block 13 described below. The mounting wall portion 55b is a portion on which the outlet block 13 described below is mounted. The mounting wall portion 55b is provided on the outer periphery of the tube portion 55a along the radial direction of the tube portion 55a. The height of each mounting wall portion 55b is formed to be the same as the lower half of the tube portion 55a.

The multiple (e.g., three) temporary fixing portions 56 (56a, 56b, 56c) are portions that temporarily fix the power cable 5 or the electric wires 5a, 5c to the back surface 50b of the cover 50. Each temporary fixing portion 56 is provided in a wall shape that rises from the back surface 50b of the cover 50.

The temporary fixing portion 56a is provided along the longitudinal direction (front-rear direction) of the cover 50 at a distance from the exposure window 18, behind the second clamping wall portion 53 and to the side of the exposure window 18. As a result, the temporary fixing portion 56a clamps the power cable 5 that has crossed the second clamping wall portion 53 between the temporary fixing portion 56a and the cutoff switch 6 behind the second clamping wall portion 53, and temporarily fixes it to the back surface 50b of the cover 50.

The temporary fixing portion 56b is provided along one of the four corners of the exposure window 18 (the rear left corner) with a gap between it and the exposure window 18. As a result, the temporary fixing portion 56b sandwiches the electric wire 5a between itself and the corner of the cutoff switch 6 and temporarily fixes it to the back surface 50b of the cover 50.

The temporary fixing portion 56c temporarily fixes the electric wire 5c, which is connected to the conductive member 12 for earthing, to the back surface 50b of the cover 50 by routing the electric wire 5c, which is connected to the conductive member 12 in a detour, to the conductive member 12 so that it has less slack than the other electric wires 5a, 5b. The temporary fixing portion 56c is provided, for example, at a position shifted to one side (for example, the left side) in the direction (left-right direction) intersecting the temporary fixing portion 56a.

As a result, when the power cable 5 is pulled, the tension at that time causes the earth wire 5c to be pulled first among the multiple electric wires 5a to 5c in the power cable 5. This makes it possible to prevent the other electric wires 5a, 5b from breaking first due to the above tension. Also, by making the lengths of the drawn-out electric wire portions (portions drawn out from the power cable 5) of each electric wire 5a to 5c the same, the order in which the electric wires 5a to 5c break can be set by the way in which the drawn-out electric wire portions of each electric wire 5a to 5c are loosened by the temporary fixing portions 56.

The multiple mounting wall portions 57 are portions on which the outlet block 13 rests. Each mounting wall portion 57 is provided in the shape of a wall rising from the back surface 50b of the cover 50. Each mounting wall portion 57 is provided at an appropriate position on the back surface 50b of the cover 50 so as to overlap with the outlet block 13.

(Electrode members 10A, 10B)
Next, the pair of electrode members 10A, 10B will be described with reference to FIGS.

As shown in Figures 4 to 6, each of the pair of electrode members 10A, 10B corresponds one-to-one with each of the pair of electrodes 202a, 202b of the attachment plug 200. Each of the pair of electrode members 10A, 10B is electrically connected to the corresponding electrode of the pair of electrodes 202a, 202b of the attachment plug 200 inserted into the outlet 2. Each of the electrode members 10A, 10B is formed of a conductive material (e.g., a metal, more specifically, a copper alloy).

The pair of electrode members 10A, 10B has multiple pairs (e.g., three pairs) of receiving portions 70 and a pair of lead portions 80A, 80B. The two receiving portions 70A, 70B (first receiving portions) in each pair of the multiple pairs of receiving portions 70 correspond one-to-one to the pair of electrode members 10A, 10B. Hereinafter, the two receiving portions 70A, 70B in a pair are also referred to as a pair of receiving portions 70A, 70B. The pair of lead portions 80A, 80B (first lead portions) also correspond one-to-one to the pair of electrode members 10A, 10B. Therefore, the two receiving portions 70A, 70B in each pair correspond one-to-one to the pair of lead portions 80A, 80B.

The electrode member 10A has a plurality of corresponding receiving portions 70A and corresponding lead portions 80A. The electrode member 10B has a plurality of corresponding receiving portions 70B and corresponding lead portions 80B. A pair of receiving portions 70A, 70B is provided for each outlet 2.

In electrode member 10A, the corresponding multiple receiving portions 70A and the corresponding lead portions 80A are formed of separate materials. Similarly, in electrode member 10B, the corresponding multiple receiving portions 70B and the corresponding lead portions 80B are formed of separate materials. The corresponding multiple receiving portions 70A, 70B and the corresponding lead portions 80A, 80B are joined by a well-known joining method (e.g., dowel crimping).

The multiple pairs (three pairs) of receiving parts 70 correspond one-to-one to the multiple (three) outlets 2, and are members that are electrically connected to a pair of electrodes 202a, 202b of the attachment plug 200 inserted into the corresponding outlet 2. The pair of receiving parts 70A, 70B correspond one-to-one to the pair of electrodes 202a, 202b of the attachment plug 200, and are electrically connected to the corresponding electrodes of the pair of electrodes 202a, 202b of the attachment plug 200. The multiple pairs (three pairs) of receiving parts 70 also correspond one-to-one to the three rear partition areas 20 of the four partition areas 20 on the back surface 50b of the cover 50, and are arranged in the corresponding partition areas 20.

The pair of receiving parts 70A, 70B are arranged at a distance from each other in the front-to-rear direction. That is, the direction in which the pair of receiving parts 70A, 70B are lined up coincides with the direction in which the three outlets 2 are lined up (front-to-rear direction). In other words, the direction in which the pair of receiving parts 70A, 70B are lined up and the direction in which the three outlets 2 are lined up are in the same direction.

The receiving portions 70A, 70B are formed to have the same shape and size as each other. In other words, the receiving portions 70A, 70B are formed as common parts. Therefore, the receiving portions 70A and 70B in the same pair, as well as the receiving portions 70A and 70B in different pairs, are formed to have the same shape and size as each other.

Each of the pair of lead portions 80A, 80B is connected to the corresponding receiving portion 70A, 70B of the multiple pairs of receiving portions 70. In addition, each of the pair of lead portions 80A, 80B is electrically connected to the corresponding electric wire 5a, 5b. Each of the pair of lead portions 80A, 80B is formed to have the same shape and size as each other. In other words, each of the pair of lead portions 80A, 80B is formed as a common part. The front end of each of the pair of lead portions 80A, 80B is provided with through holes 80Aa, 80Ba to which the electric wires 5a, 5e are connected. The electric wire 5e is an electric wire that is electrically connected to the electric wire 5b via the cutoff switch 6.

As shown in FIG. 6, each lead portion 80A, 80B has a plurality of bonding regions 80Ab, 80Bb to which a corresponding plurality of receiving portions 70A, 70B are bonded. The bonding regions 80Ab, 80Bb are formed at intervals in the longitudinal direction of each lead portion 80A, 80B. As described above, each lead portion 80A, 80B is formed to have the same shape and size, so the arrangement of each bonding region 80Ab, 80Bb on each lead portion 80A, 80B is also the same.

As shown in FIG. 5, the lead portions 80A and 80B are arranged on the back surface 50b of the cover 50. In this arrangement, the lead portions 80A and 80B are arranged along the longitudinal direction (front-rear direction) of the cover 50. The lead portions 80A and 80B are also arranged at intervals from each other in the left-right direction of the cover 50. The lead portions 80A and 80B are also arranged with a shift from each other in the longitudinal direction. For example, the lead portion 80B is shifted forward from the lead portion 80A. The shape orientations of the lead portions 80A and 80B are aligned in the same direction. The shape orientation of the lead portions 80A and 80B refers to, for example, the direction in which the lead portions 80A and 80B extend and the front and back of the lead portions 80A and 80B.

In addition, each lead portion 80A, 80B is biased toward one side in the left-right direction (e.g., the right side) on the back surface 50b of the cover 50. This ensures that there is space to place the conductive member 12 for earthing on the other side in the left-right direction (e.g., the left side) on the back surface 50b of the cover 50.

A plurality of receiving portions 70A are connected to one lead portion 80A, and a plurality of receiving portions 70B are connected to the other lead portion 80B. In one lead portion 80A, the receiving portions 70A are connected to the connection region 80Ab of the lead portion 80A, so that they are spaced apart from each other in the longitudinal direction of the lead portion 80A. In addition, in one lead portion 80A, each receiving portion 70A is arranged so that it protrudes toward the other lead portion 80B side and protrudes higher than both lead portions 80A and 80B. Similarly, in the other lead portion 80B, each receiving portion 70B is arranged so that it protrudes toward the other lead portion 80A side and protrudes higher than both lead portions 80A and 80B.

The pairs of receiving parts 70 are arranged at intervals from each other in the longitudinal direction of the pair of lead parts 80A, 80B. Each pair of receiving parts 70A, 70B is also arranged at intervals from each other in the longitudinal direction of the pair of lead parts 80A, 80B. The pairs of receiving parts 70 are arranged between each pair of lead parts 80A, 80B and protrude above the pair of lead parts 80A, 80B. Each pair of receiving parts 70 is arranged on the back side of the corresponding partition area 20 on the back surface 50b of the cover 50. The two receiving parts 70A, 70B in each pair are arranged on the back side (lower side) of each pair of insertion holes 21a, 21b provided in the corresponding partition area 20.

The shape of each lead portion 80A, 80B and each receiving portion 70A, 70B will be described with reference to Figure 6.

As shown in FIG. 6, each lead portion 80A, 80B is formed, for example, in the shape of a strip extending in the front-to-rear direction. The thickness direction of each lead portion 80A, 80B coincides with the up-to-down direction (i.e., the insertion/removal direction of the attachment plug 200). In other words, the main surfaces on both sides of each lead portion 80A, 80B extend in the front-to-back and left-to-right directions.

Each lead portion 80A, 80B is provided with a plurality of recesses 81. Each recess 81 is provided in each lead portion 80A, 80B in a portion adjacent to the unconnected one of the two receiving portions 70A, 70B in each pair. This recess 81 can further ensure the insulation distance between the lead portion 80A and the receiving portion 70B that is not connected to this lead portion 80A. Similarly, this recess 81 can further ensure the insulation distance between the lead portion 80B and the receiving portion 70A that is not connected to this lead portion 80B.

More specifically, the recesses 81 are provided alternately on both the left and right side surfaces of the lead portion 80A along the longitudinal direction of the lead portion 80A. That is, on the left side surface of the lead portion 80A, multiple recesses 81 are provided at intervals from each other along the longitudinal direction of the lead portion 80A. On the right side surface of the lead portion 80A, multiple recesses 81 are provided at intervals from each other along the longitudinal direction of the lead portion 80A and adjacent to the intervals between the recesses 81 on the left side surface of the lead portion 80A. The same is true for each recess 81 of the lead portion 80B.

A plurality of bonding regions 82 are formed on the upper surface of the lead portion 80A. The bonding regions 82 are formed at intervals in the longitudinal direction on the upper surface of the lead portion 80A. More specifically, the bonding regions 82 are formed at regular intervals from one another on the upper surface of the lead portion 80A so as not to overlap with the recesses 81. In this embodiment, the bonding regions 82 are formed between the recesses 81 that are alternately arranged on the left and right sides of the lead portion 80A along the front-rear direction of the lead portion 80A, every two of the recesses 81 that are alternately arranged on the left and right sides of the lead portion 80A. The same is true for the bonding regions 82 of the lead portion 80B.

The receiving portion 70A coupled to each of the coupling regions 82 of one lead portion 80A protrudes toward the other lead portion 80B and is disposed above the upper surfaces of both lead portions 80A and 80B. Each coupling region 82 of one lead portion 80A is disposed in front of one of the multiple recesses 81 provided in the other lead portion 80B. Therefore, the receiving portion 70A coupled to each of the coupling regions 82 of one lead portion 80A is disposed near the front of one of the multiple recesses 81 provided in the other lead portion 80B. In this way, the recesses 81 provided in the lead portions 80A and 80B further ensure the insulation distance between the lead portions 80A and 80B and the receiving portions 70B and 70A that are not connected to the lead portions 80A and 80B.

Two protrusions 82a are provided in each bonding region 82 of the lead portion 80A. The two protrusions 82a fit into two bonding holes 74a of a bonding portion 74 (described below) of the receiving portion 70A that is bonded to the bonding region 82. When the two protrusions 82a fit into the two bonding holes 74a, the two protrusions 82a are crushed, bonding the bonding portion 74 and the bonding region 82. In other words, the receiving portion 70A and the lead portion 80A are bonded. Similarly, two protrusions 82a are provided in each bonding region 82 of the lead portion 80B.

A reinforcing rib 83 is provided on each lead portion 80A, 80B. The reinforcing rib 83 protrudes from one of the main surfaces (e.g., the upper surface) on both sides of each lead portion 80A, 80B, and is formed along the longitudinal direction of each lead portion 80A, 80B. The reinforcing rib 83 is not formed in each bonding region 82 of each lead portion 80A, 80B. The reinforcing rib 83 is provided, for example, by being pushed out (e.g., by pressing) from the other main surface (e.g., the lower surface) on both sides of each lead portion 80A, 80B toward one main surface (e.g., the upper surface).

The front end of each lead portion 80A, 80B is provided with a connection hole 84 to which the electric wires 5a, 5e are electrically connected. The front end of each lead portion 80A, 80B is raised in a stepped shape. By raising the front end of each lead portion 80A, 80B in this way in a stepped shape, the front end of each lead portion 80A, 80B is formed at a height suitable for connecting the electric wires 5a, 5e.

As shown in Figures 6 and 7, each receiving portion 70A, 70B has multiple (e.g., three) elastic pieces 71, a support portion 72 that supports the multiple elastic pieces 71, a connecting portion 73, and a joining portion 74.

Each receiving portion 70A, 70B is electrically connected to the corresponding electrodes 202a, 202b of the attachment plug 200 by sandwiching the corresponding electrodes 202a, 202b with, for example, three elastic piece portions 71. Of the three elastic piece portions 71, for example, the two elastic piece portions 71a on the left and right sides are arranged with their main surfaces facing each other and spaced apart. Of the three elastic piece portions 71, the remaining elastic piece portion 71b is arranged with its main surface facing the side edges of the two elastic piece portions 71a and spaced apart from the two elastic piece portions 71a.

Each receiving portion 70A, 70B is arranged so that the tips (upper portions) of the three elastic pieces 71 face the cover 50 side (i.e., the upper side). By forming the three elastic pieces 71 in this way, the corresponding electrodes 202a, 202b can be elastically sandwiched between two elastic pieces 71a, or between two elastic pieces 71a and the remaining elastic piece 71b. Each receiving portion 70A, 70B can be integrally formed, for example, by bending a metal plate that has a shape similar to the development of the receiving portion 70A, 70B.

The support portion 72 is formed, for example, in the shape of a generally U-shaped peripheral wall that encloses three of the four sides and opens the remaining side. The support portion 72 is integrally connected to the base ends of the three elastic piece portions 71 at three points in the longitudinal direction on the tip edge (upper edge) of the generally U-shape.

The connecting portion 73 is a portion that connects the support portion 72 and the joining portion 74. The connecting portion 73 extends downward from a portion of the base end side (lower side) of the approximately U-shape of the support portion 72 that is adjacent to the corresponding lead portion 80A, 80B, and is bent toward the corresponding lead portion 80A, 80B to join to the joining portion 74. In other words, the connecting portion 73 is bent into an approximately L-shape when viewed from the longitudinal direction (front-to-back direction) of the lead portions 80A, 80B.

The coupling portion 74 is a portion that couples with the coupling region 82 of each lead portion 80A, 80B. The coupling portion 74 of each receiving portion 70A, 70B couples with the coupling region 82 of the corresponding lead portion of each lead portion 80A, 80B. The coupling portion 74 is formed in a plate shape of approximately the same shape and size as each coupling region 82 of the lead portions 80A, 80B. The coupling portion 74 is provided with multiple (e.g., two) coupling holes 74a (see FIG. 6). The multiple coupling holes 74a of the coupling portion 74 are holes into which the multiple protrusions 82a of the coupling region 82 of the lead portions 80A, 80B are fitted. When the protrusions 82a are fitted into the coupling holes 74a, the protrusions 82a are crushed, and the coupling portion 74 and the coupling region 82 are coupled. In other words, the receiving portions 70A, 70B and the lead portions 80A, 80B are coupled.

As shown in FIG. 7, by forming the connecting portion 73 of each receiving portion 70A, 70B into a substantially L-shape as described above, each receiving portion 70A, 70B can be arranged with a distance K1 above the upper surface 80a of each lead portion 80A, 80B. This allows each receiving portion 70A, 70B to be arranged with a distance K1 above the upper surface 80a of the lead portion 80B, 80A that is not connected to each receiving portion 70A, 70B. As a result, the distance K1 can further ensure the insulation distance between each lead portion 80A, 80B and the receiving portion 70B, 70A that is not connected to each lead portion 80A, 80B. The distance K1 is the distance between each lead portion 80A, 80B and the receiving portion 70B, 70A that is not connected to each lead portion 80A, 80B in the vertical direction (the insertion/removal direction of the plug 200).

(Earth conductive member 12)
Next, the conductive member 12 for earthing will be described with reference to FIG.

The conductive member 12 is a member that is electrically connected to the ground terminal 202c of the plug 200 that is inserted into the outlet 2. The conductive member 12 is made of a conductive material (e.g., a metal, more specifically, for example, brass).

The conductive member 12 has a plurality of receiving portions 90, a lead portion 91, a plurality of connecting portions 92, and one or more connecting portions 93. The conductive member 12 is integrally formed. The conductive member 12 can be integrally formed, for example, by bending a metal plate that has a shape similar to the development view of the conductive member 12.

The multiple (e.g., three) receiving portions 90 correspond one-to-one to the multiple (three) outlets 2, and are members that are electrically connected to the ground terminals 202c of the attachment plugs 200 inserted into the corresponding outlets 2. The multiple receiving portions 90 correspond one-to-one to the three rear partition areas 20 of the four partition areas 20 on the back surface 50b of the cover 50.

Each receiving portion 90 has multiple (e.g., two) elastic pieces 90a. Each receiving portion 90 is electrically connected to the ground terminal 202c of the attachment plug 200 by sandwiching the ground terminal 202c between the two elastic pieces 90a. The two elastic pieces 90a are arranged with their main surfaces facing each other and spaced apart from each other. The base ends (lower ends) of the two elastic pieces 90a are bent in opposing directions and connected to each other. Each receiving portion 90 is arranged so that the tips (upper parts) of the two elastic pieces 90a face the side (upper side) where the ground terminal 202c is inserted.

The lead portion 91 supports the multiple receiving portions 90 and is a portion to which the electric wire 5c is electrically connected. The lead portion 91 is formed, for example, in the shape of a strip extending in the front-to-rear direction. The thickness direction of the conductive member 12 coincides with the left-to-right direction. In other words, the main surfaces on both sides of the conductive member 12 extend in the front-to-rear and up-to-down directions. The multiple connecting portions 92 connect the multiple receiving portions 90 and the lead portion 91 and correspond one-to-one to the multiple receiving portions 90.

The multiple receiving portions 90 are spaced apart from one another in the longitudinal direction of the lead portion 91 and are connected via corresponding connecting portions 92. Each receiving portion 90 is disposed on one of the left and right sides of the lead portion 91 (e.g., the right side). Each connecting portion 92 extends downward from the lower side of the lead portion 91, bends toward the receiving portion 90, and is connected to the lower end of the receiving portion 90.

One or more (e.g., three) connection parts 93 are portions to which the electric wire 5c is electrically connected. Each connection part 93 is provided with a connection hole 93a to which the electric wire 3c is connected. Each connection part 93 is provided at intervals from one another along the longitudinal direction of the lead part 91. Each connection part 93 is formed, for example, in a piece shape and protrudes from the lower side of the lead part 91 to one of the left and right sides of the lead part 91 (e.g., the right side). In this embodiment, the electric wire 5c is electrically connected to, for example, the frontmost connection part 93 of the three connection parts 93.

As shown in FIG. 5, the conductive member 12 is disposed on the back surface 50b of the cover 50. The conductive member 12 is disposed next to the electrode member 10B (i.e., next to the opposite side of the electrode member 10A) with a gap between them. Therefore, the electrode members 10A, 10B, and the conductive member 12 are disposed extending in the front-rear direction and with a gap between them in the left-right direction.

In this arrangement, the lead portion 91 of the conductive member 12 is arranged along the longitudinal direction (front-rear direction) of the cover 50. The lead portion 91 is arranged on the rear surface 50b of the cover 50, for example, in the space to the left of the two electrode members 10A, 10B. Each receiving portion 90 of the conductive member 12 is arranged in a corresponding partitioned area 20 on the rear surface 50b of the cover 50. Each receiving portion 90 is arranged on the rear side (below) of the insertion hole 21c of the corresponding partitioned area 20. The insertion hole 21c is a hole into which the ground terminal 202c of the insertion plug 200 is inserted.

(Outlet block 13)
Next, the outlet block 13 will be described with reference to FIGS. 9A, 9B and 5. FIG.

As shown in Figures 9A and 9B, the multiple (e.g., three) outlet blocks 13 correspond one-to-one to the multiple (e.g., three) outlets 2, and are portions that hold a pair of receiving portions 70 (70A, 70B) corresponding to the corresponding outlets 2, and receiving portions 90. In other words, each of the multiple outlet blocks 13 is provided for each of the multiple outlets 2. The multiple outlet blocks 13 correspond one-to-one to the three rear partition areas 20 out of the four partition areas 20 on the back surface 50b of the cover 50, and are arranged in the corresponding partition areas 20 (see Figure 5).

Each outlet block 13 is formed to have the same shape and size. That is, each outlet block 13 is formed as a common part. Each outlet block 13 is formed, for example, in a substantially rectangular parallelepiped shape. Each outlet block 13 is formed, for example, from a thermosetting resin such as urea resin.

Each outlet block 13 is provided with three storage sections 100a, 100b, and 100c. Of the three storage sections 100a to 100c, a pair of storage sections 100a and 100b each store a pair of receiving sections 70A and 70B. The remaining storage section 100c stores the receiving section 90.

Each of the storage sections 100a, 100b is formed, for example, in a hollow shape of a substantially rectangular parallelepiped, penetrates the outlet block 13 in the vertical direction, and has openings on both the upper and lower surfaces of the outlet block 13. The storage sections 100a, 100b are provided at intervals from each other in the front-to-rear direction in the outlet block 13.

The inner circumferential surface of the storage section 100a is provided with a plurality of (e.g., three) hooks 101. Each hook 101 is provided on the inner circumferential surface of the storage section 100a, on the periphery of the lower opening side of the storage section 100a. Each hook 101 protrudes toward the inside of the storage section 100a. Each hook 101 prevents the receiving section 70A accommodated in the storage section 100a from coming out of the storage section 100a. Similarly, the inner circumferential surface of the storage section 100b is also provided with a plurality of (e.g., three) hooks 101.

The accommodation section 100c is formed, for example, in a substantially rectangular parallelepiped shape, and is formed in a concave shape toward the lower surface on the upper surface (i.e., the surface on the cover 50 side) of the outlet block 13. A plurality of protrusions 103 are provided on the inner peripheral surface of the accommodation section 100c. The plurality of (for example, two) protrusions 103 are protrusions for ensuring a gap between each elastic piece 90a and the inner peripheral surface of the accommodation section 100c by contacting the base end (lower end) of the side surface of each elastic piece 90a of the reception section 90 when the reception section 90 is accommodated in the accommodation section 100c. As a result, when the reception section 90 is accommodated in the accommodation section 100c, the upper part of each elastic piece 90a of the reception section 90 is no longer in contact with the inner peripheral surface of the accommodation section 100c, and becomes elastically movable. Each protrusion 103 is provided on both sides of the notch 132 described later and on the bottom (lower) side of the accommodation section 100c.

The left side surface (outer surface) of the outlet block 13 is provided with a notch 132 and multiple protrusions 133. The notch 132 is a portion where the connecting portion 92 that connects to the receiving portion 90 is located when the receiving portion 90 is accommodated in the accommodation portion 100c. The notch 132 is a strip-like portion extending in the vertical direction, and is open at the peripheral portion (opening edge portion) of the upper opening of the accommodation portion 100c. The multiple protrusions 133 are portions that hook onto the lead portion 91 when the lead portion 91 is arranged on the left side surface of the outlet block 13, thereby positioning the lead portion 91. Each protrusion 133 is provided on both sides of the notch 132 on the left side surface of the outlet block 13. Also, each protrusion 133 is provided at a middle position in the vertical direction on the left side surface of the outlet block 13.

The outlet block 13 is provided with a plurality of (e.g., three) positioning holes 134. The positioning holes 134 are holes into which a plurality of positioning portions 55 provided in the corresponding partitioned areas 20 of the rear surface 50b of the cover 50 fit. The positioning holes 134 are provided at appropriate positions on the outer periphery of the outlet block 13. In this embodiment, two corners (e.g., the left front corner and the left rear corner) of the bottom surface of the outlet block 13 are formed low in a stepped shape, and one positioning hole 134 is provided at each of the two corners. In addition, a flange portion 135 is formed so as to protrude forward from the right end of the front edge of the top surface of the outlet block 13, and one positioning hole 134 is provided in the flange portion 135.

As shown in FIG. 5, the pair of receiving portions 70 and 90 are accommodated (held) in the outlet block 13 thus formed as follows.

Each of the pair of receiving parts 70A, 70B is received in each of the receiving parts 100a, 100b from the lower surface of the outlet block 13. In this receiving state, the hook part 101 of each of the receiving parts 100a, 100b is hooked on the base end (lower end) of each of the receiving parts 70A, 70B. This prevents each of the receiving parts 70A, 70B from slipping out of the lower opening of each of the receiving parts 100a, 100b. In addition, the lead parts 80A, 80B connected to each of the receiving parts 70A, 70B abut the lower surface of the outlet block 13. This prevents each of the receiving parts 70A, 70B from slipping out of the upper opening of each of the receiving parts 100a, 100b. This fixes each of the receiving parts 70A, 70B in the receiving parts 100a, 100b, and fixes each of the lead parts 80A, 80B to the lower surface of the outlet block 13. As a result, a pair of electrode members 10A, 10B are fixed to the upper surface of each outlet block 13.

The receiving portion 90 is received in the receiving portion 100c from the upper surface of the outlet block 13 (see FIG. 2). In this received state, the connecting portion 92 connected to the receiving portion 90 is disposed in the notch 132 and contacts the bottom (lower end) of the notch 132 (see FIG. 5). Also, the lead portion 91 connected to the connecting portion 92 is disposed below the protrusion 133 across the protrusion 133 on the left side surface of the outlet block 13. As a result, the upward movement of the lead portion 91 is restricted by the protrusion 133. Also, the downward movement of the lead portion 91 is restricted by the connecting portion 92 abutting against the bottom of the notch 132. That is, the lead portion 91 is positioned and disposed on the left side surface of the outlet block 13. Also, the wall portion 136 constituting the left side surface of the outlet block 13 and the inner peripheral surface of the receiving portion 90 and the lead portion 91 is sandwiched between the receiving portion 90 and the lead portion 91. This fixes the receiving portion 90 to the housing portion 100c, and the lead portion 91 to the left side surface of the outlet block 13. As a result, the conductive member 12 for earthing is fixed to the left side surface of each outlet block 13.

Furthermore, each outlet block 13 thus formed is placed in the corresponding partition area 20 on the back surface 50b of the cover 50. In this arrangement, each outlet block 13 is placed on a mounting wall portion 57 provided in the corresponding partition area 20. Furthermore, each positioning hole 134 of each outlet block 13 fits into each positioning portion 55 provided in the corresponding partition area 20. This determines the position of each outlet block 13 on the back surface 50b of the cover 50.

(Shut-off switch 6)
Next, the cutoff switch 6 will be described with reference to FIGS.

The cutoff switch 6 connects or disconnects the electric wire 5b electrically connected to the electrode member 10B. In this embodiment, an electric wire 5e is connected between the electrode member 10B and the electric wire 5b, and the cutoff switch 6 is connected between each of the electric wires 5e, 5e. The cutoff switch 6 connects or disconnects the electric wire 5b electrically connected to the electrode member 10B by connecting or disconnecting the electric wires 5b, 5e.

In this embodiment, the cutoff switch 6 connects or disconnects the electric wire 5b electrically connected to the electrode member 10B, but may also connect or disconnect the electric wire 5a electrically connected to the electrode member 10A.

The cutoff switch 6 is connected between the electrode member 10B and the electric wire 5b electrically connected to the electrode member 10B, and provides or blocks electrical continuity between the electrode member 10B and the electric wire 5b. In this embodiment, the cutoff switch 6 provides or blocks electrical continuity between the electrode member 10B and the electric wire 5b, but may also be connected between the electrode member 10A and the electric wire 5a electrically connected to the electrode member 10A, and provides or blocks electrical continuity between the electrode member 10A and the electric wire 5a.

The cutoff switch 6 has a switch case 6a and a switch body 6b.

The switch body 6b is connected between the electric wires 5b and 5e, and can be manually switched on or off to interrupt or connect the electric wires 5b and 5e. When a current of a predetermined value or more (i.e., an overcurrent) flows through the electric wire 5b, the switch body 6b automatically switches from on to off, interrupting or connecting the electric wires 5b and 5e (overcurrent prevention function). The switch body 6b has two connection terminals 6c and 6d to which the electric wires 5b and 5e are connected.

The switch case 6a is formed, for example, in the shape of a roughly rectangular box. The top surface of the switch case 6a is formed in a shape (for example, roughly rectangular) that is slightly larger than the exposure window 18 of the cover 50. The switch body 6b is disposed on the top surface of the switch case 6a (see FIG. 2), and two connection terminals 6c, 6d are provided protrudingly on the bottom surface of the switch case 6a (see FIG. 4).

The cutoff switch 6 thus configured is placed on the back surface 50b of the cover 50, with the top surface of the switch case 6a overlapping the exposure window 18 of the cover 50. In this position, the switch body 6b is exposed from the exposure window 18 (see FIG. 1).

(Assembly procedure)
Next, a procedure (assembly method) for assembling the table tap 1 will be described.

In this table tap 1, the various components 8 are placed on the back surface 50b of the cover 50, and then the cover 50 is attached to the opening 40a of the body 40. First, the assembly procedure on the cover 50 side (i.e., the procedure for placing the various components 8 on the cover 50) will be described with reference to Figures 4 and 5.

First, the cutoff switch 6 is arranged on the back surface 50b of the cover 50 so as to overlap the exposure window 18. Next, the conductive member 12 for earthing is arranged on the back surface 50b of the cover 50. In this arrangement, the lead portion 91 of the conductive member 12 is arranged on the left side of the back surface 50b of the cover 50, extending in the front-to-rear direction of the cover 50. Each receiving portion 90 of the conductive member 12 is arranged below the insertion hole 21c of the corresponding partition area 20 on the back surface 50b of the cover 50.

Next, the multiple outlet blocks 13 are placed in the corresponding partition areas 20 on the back surface 50b of the cover 50. At this time, each outlet block 13 accommodates the corresponding receiving portion 90 of the conductive member 12 from the upper surface side of the outlet block 13 (i.e., the cover 50 side). As a result, as described above, the corresponding receiving portion 90 is accommodated in the accommodation portion 100c of the outlet block 13. Also, the connecting portion 92 connected to the receiving portion 90 is placed at the bottom of the notch portion 132 of the outlet block 13. Also, the lead portion 91 of the conductive member 12 (i.e., the lead portion 91 connected to the connecting portion 92) is fixed to the left side surface of the outlet block 13. As a result, the conductive member 12 is fixed to the left side surface of each outlet block 13.

The positioning holes 134 of each outlet block 13 fit into the positioning portions 55 of the corresponding partition area 20. This positions each outlet block 13 at a predetermined position in the corresponding partition area 20.

Next, a pair of electrode members 10A, 10B are placed on the back surface 50b of the cover 50. At this time, each receiving portion 70A of the electrode member 10A is accommodated in the accommodation portion 100a of the outlet block 13 arranged in the corresponding partitioned area 20 from the bottom side of the outlet block 13. Similarly, each receiving portion 70B of the electrode member 10B is accommodated in the accommodation portion 100b of the outlet block 13 arranged in the corresponding partitioned area 20 from the bottom side of the outlet block 13. As a result, as described above, the two receiving portions 70A, 70B in each pair are accommodated in the accommodation portions 100a, 100b of the corresponding outlet block 13. In addition, the lead portions 80A, 80B of each electrode member 10A, 10B are fixed to the bottom surface of each outlet block 13. As a result, each electrode member 10A, 10B is fixed to the top surface of each outlet block 13.

Next, the power cable 5 is passed through the wire hole 4 of the body 40. The power cable 5 passed through the wire hole 4 is temporarily fixed to the back surface 50b of the cover 50 by being sandwiched between the temporary fixing portion 56a and the cutoff switch 6. The same length of each of the electric wires 5a, 5b, 5c is drawn out from the end of the exterior 5d of the power cable 5. This drawn out portion of each of the electric wires 5a, 5b, 5c is referred to as the drawn out electric wire portion 5a1, 5b1, 5c1. The drawn out electric wire portions 5a1, 5b1, 5c1 of each of the electric wires 5a, 5b, 5c are the same length.

Then, the lead wire portion 5a1, 5b1, 5c1 of each electric wire 5a, 5b, 5c is electrically connected to the corresponding electrode member 10A, 10B or conductive member 12. That is, the lead wire portion 5a1 is passed through the connection hole 84 of the lead portion 80A of the electrode member 10A and electrically connected. The lead wire portion 5b1 is passed through the connection hole of the connection terminal 6c of the cutoff switch 6 and electrically connected. Also, the connection terminal 6d of the cutoff switch 6 and the lead portion 80B of the electrode member 10B are electrically connected to each other by the electric wire 5e. Therefore, the lead wire portion 5b1 is electrically connected to the lead portion 80B via the cutoff switch 6 and the electric wire 5e. The lead wire portion 5c1 is passed through the connection hole 93a of the lead portion 91 of the conductive member 12 for earthing and electrically connected.

The lead wire portion 5a1 connected to the electrode member 10A is temporarily fixed to the back surface 50b of the cover 50 by being sandwiched between the temporary fixing portion 56b and the corner of the cutoff switch 6. The lead wire portion 5c1 connected to the conductive member 12 is temporarily fixed to the back surface 50b of the cover 50 by being routed around the outside of the temporary fixing portion 56c. In this way, the wires 5a, 5c are temporarily fixed to the back surface 50b of the cover 50, so that the wires 5a, 5c can be prevented from being sandwiched between the cover 50 and the body 40 when the cover 50 is attached to the opening 40a of the body 40.

In the above-mentioned temporarily fixed state, of the three draw-out electric wire portions 5a1, 5b1, and 5c1, the draw-out electric wire portion 5c1 of the earth electric wire 5c is less loose than the draw-out electric wire portions 5a1 and 5c1 of the other electric wires 5a and 5b. To achieve this, the draw-out electric wire portion 5c1 of the earth electric wire 5c is temporarily fixed to the cover 50 by the temporary fixing portion 56. This makes it possible to ensure that, when the same tension is simultaneously applied to each electric wire 5a, 5b, and 5c, the earth electric wire 5c is pulled first among the three electric wires 5a, 5b, and 5c by that tension. This makes it possible to prevent the other electric wires 5a and 5b from breaking first due to the above-mentioned tension. In addition, the lengths of the lead wire portions 5a1, 5b1, and 5c1 of the electric wires 5a, 5b, and 5c are made the same, and the order in which the electric wires 5a, 5b, and 5c are cut can be set by the way in which the lead wire portions 5a1, 5b1, and 5c1 of the electric wires 5a, 5b, and 5c are loosened by the temporary fixing portions 56.

In this way, the various components 8 are placed on the back surface 50b of the cover 50. The opening 40a of the body 40 is then closed with the cover 50. Then, each screw N1 is screwed from the outside of the body 40 through each through hole 62b of the body 40 into the screw hole 54b of each boss portion 54 of the cover 50. This fixes the cover 50 to the opening 40a of the body 40, and the table tap 1 is assembled (see Figure 1).

As shown in FIG. 1, in this assembled state, the outer periphery 50a of the cover 50 fits inside the opening 40a of the body 40. As a result, the outer periphery 50a of the cover 50 is protected by the body 40. Also, the outer wall 51 of the cover 50 fits into the recess 60b of the vertical rib 60 of the body 40. As a result, the position of the cover 50 on the opening surface of the opening 40a of the body 40 is determined. Also, the lower surface of each outlet block 13 arranged on the back surface 50b of the cover 50 is pressed by a plurality of protrusions 63 provided on the bottom wall 41 of the body 40. As a result, the position of each outlet block 13 in the vertical direction is determined. The position of each outlet block 13 within the housing 3 is determined by these protrusions 63 and the positioning portion 55.

As shown in FIG. 10, the power cable 5 is clamped between the first clamping wall 61 and the second clamping wall 53 inside the housing 3. As a result, even if the power cable 5 is pulled outside the housing 3, the tension at that time can be stopped by the clamping section 17 formed by the first clamping wall 61 and the second clamping wall 53. As a result, even if the power cable 5 is pulled outside the housing 3, the electric wires 5a, 5b, 5c inside the power cable 5 can be prevented from coming off the electric components (10A, 10B, 12).

Note that the above assembly procedure is an example, and the order in which the various parts are placed on the cover may be changed as appropriate.

(summary)
The table tap (1) according to the first aspect includes a housing (3), a receiving portion (70A, 70B, 90), a lead portion (80A, 80B, 91), and electric wires (5a, 5b, 5c). The housing (3) has an insertion hole (21) into which a conductor (202) of an attachment plug (200) is inserted. The receiving portion (70A, 70B, 90) is housed in the housing (3) and electrically connected to the conductor (202) inserted in the insertion hole (21). The lead portion (80A, 80B, 91) is housed in the housing (3) and connected to the receiving portion (70A, 70B, 90). The electric wires (5a, 5b, 5c) are electrically connected to the lead portions (80A, 80B, 91). The housing (3) includes a cover (50) and a body (40). The cover (50) has an insertion hole (21). The body (40) has an opening (40a) and an internal space (40f). The cover (50) is attached to the opening (40a). The internal space (40f) is connected to the opening (40a). The body (40) accommodates the receiving portion (70A, 70B, 90) and the lead portion (80A, 80B, 91) in the internal space (40f). The body (40) has an electric wire hole (4) that is closed all around. The electric wires (5a, 5b, 5c) are arranged through the electric wire hole (4).

According to this configuration, the body (40) of the body (40) and the cover (50) is provided with an electric wire hole (4) for drawing the electric wires (5a, 5b, 5c) from the inside to the outside of the housing (3). Since the entire circumference of the electric wire hole (4) is closed, even if the electric wire hole (4) is provided in the body (40), the strength and rigidity of the body (40) can be prevented from being reduced by the electric wire hole (4).

In the table tap (1) according to the second aspect, in the first aspect, the housing (3) has a clamping portion (17). The clamping portion (17) clamps the electric wires (5a, 5b, 5c) that have passed through the electric wire holes (4) in the internal space (40f).

With this configuration, even if the electric wires (5a, 5b, 5c) are pulled outside the housing (3), the tension at that time can be stopped by the clamping portion (17) and prevented from being transmitted to the lead portions (80A, 80B, 91). As a result, even if the electric wires (5a, 5b, 5c) are pulled outside the housing (3), the electric wires (5a, 5b, 5c) can be prevented from coming off the lead portions (80A, 80B, 91). Hereinafter, this effect is also referred to as tension stop.

In the table tap (1) according to the third aspect, in the first or second aspect, the clamping portion (17) has a first clamping wall portion (61) and a second clamping wall portion (53). The first clamping wall portion (61) is provided on the body (40). The second clamping wall portion (53) is provided on the cover (50). When the cover (50) is attached to the opening (40a), the electric wires (5a, 5b, 5c) are clamped by the first clamping wall portion (61) and the second clamping wall portion (53).

According to this configuration, by attaching the cover (50) to the opening (40a) of the body (40), the electric wires (5a, 5b, 5c) can be clamped by the clamping portion (17). Therefore, the task of clamping the electric wires (5a, 5b, 5c) by the clamping portion (17) can be essentially omitted. As a result, the efficiency of the assembly work of the table tap (1) can be improved.

In the table tap (1) according to the fourth aspect, in the third aspect, the first clamping wall portion (61) has a plurality of first walls (61a). The plurality of first walls (61a) are arranged at intervals in the thickness direction. The second clamping wall portion (53) has a plurality of second walls (53a). The plurality of second walls (53a) are arranged at intervals in the thickness direction.

This configuration increases the frictional resistance between the first clamping wall portion (61) and the second clamping wall portion (53) and the electric wires (5a, 5b, 5c), thereby improving the effect of tension stop. In addition, the pressure acting on the electric wires (5a, 5b, 5c) from the first clamping wall portion (61) and the second clamping wall portion (53) can be dispersed, thereby reducing the burden on the electric wires (5a, 5b, 5c).

In the table tap (1) according to the fifth aspect, in the third or fourth aspect, the body (40) has a first boss portion (62a) formed integrally with the first clamping wall portion (61) on at least one of both ends of the first clamping wall portion (61). The cover (50) has a second boss portion (54a) formed integrally with the second clamping wall portion (53) on at least one of both ends of the second clamping wall portion (53).

With this configuration, the first boss portion (62a) can improve the strength and rigidity of the first clamping wall portion (61). Also, the second boss portion (54a) can improve the strength and rigidity of the second clamping wall portion (53). As a result, the effect of tension stop can be further improved.

In the table tap (1) according to the sixth aspect, in the fifth aspect, when the cover (50) is attached to the opening (40a) of the body (40), the first boss portion (62a) and the second boss portion (54a) are fastened to each other.

According to this configuration, the cover (50) can be fixed to the body (40) by fastening the first boss portion (62a) and the second boss portion (54a) to each other.

The lower portion (60d) of the vertical rib (60) is inclined toward the inside of the body (40) along the lower portion (G2) of the inner peripheral surface (46b).

With this configuration, the lower portion (60d) of the vertical rib (60) is inclined along the inclination of the inner peripheral surface (46b) of the body (40), which prevents the width of the vertical rib (60) from becoming narrower as it approaches the lower portion (60d). As a result, the strength and rigidity of the lower portion (60d) of the vertical rib (60) can be ensured.

In the table tap (1) according to the twelfth aspect, in any one of the eighth to eleventh aspects, the height of the inner wall portion (52) relative to the cover (50) is greater than the height of the outer wall portion (51) relative to the cover (50).

With this configuration, the inner wall portion (52) is higher than the outer wall portion (51), which improves the strength and rigidity of the cover (50). Also, the inner wall portion (52) is higher than the outer wall portion (51). Therefore, even if the inner circumferential surface (46b) of the body (40) is inclined toward the inside of the body (40) toward the lower portion (G2), it is possible to prevent both the inner wall portion (52) and the outer wall portion (51) from interfering with the inner circumferential surface (46b) of the body (40).

The table tap (1) according to the thirteenth aspect is any one of the first to twelfth aspects, and further includes a cutoff unit (6). The cutoff unit (6) cuts off the electric wires (5a, 5b) when a current of a predetermined current value or more flows through the electric wires (5a, 5b).

This configuration protects the table tap (1) from overcurrent.
