Description

Γ 278160 玖, invention description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a wiring device. [Prior Art]

In general, the wiring device includes a device body that is coupled to a main body by two parts. The one wall socket has a device body which is provided by coupling a cover and an insertion opening, the insertion opening being at a front portion and a rear body. A plug has a device body that is configured by coupling a front outer cover having an operating portion and a rear body. The coupling of the body and the outer cover is proposed in Japanese Patent Unexamined Publication No. Hei 10-326658, in which a component projection formed at one side of a body and a cover is coupled to a component formed on the other side. Concave. With the above configuration, it is possible to reduce the number of parts and easily realize the case of using the components of the screw coupling body and the cover. In addition, several types of buried wiring devices have been proposed which have a rear side embedded in a construction surface, wherein a main system is attached to a mounting frame fixed to the construction surface, and a cover is formed A claw or recess for coupling the body to the mounting frame. In the main body of the wiring device, since the cover is provided with a configuration coupled to a member (for example, a mounting frame) for fixing the main body to the structural surface, if the assembly convex portion and the concave portion of the main body and the outer cover are coupled to each other The cover may be detached from the body when one of the ruptures or the coupling force is weak. In particular, if heat shrinkage occurs in the body and the outer cover, the coupling force will be weakened, so the 3 Γ 278160 outer cover will be phased, combined, and external.

The set at the rear side body is fixed with a front mounting and a cover that protrudes from the outer cover surface and may be separated from the body. Since the material having the same heat shrinkage rate must be selected for the body and the cover, the degree of freedom in selecting the material becomes low. In order to solve the above problems, an object of the present invention is to provide a wiring device in which the coupling between the convex portion and the concave portion of the coupling body and the outer cover is weakened, the outer cover is not separated from the body, and the material is selected for the body. The degree of freedom of the cover becomes high. According to an exemplary embodiment, the present invention provides a wiring device comprising: a body having a front surface embedded in a structural surface and exposed from the surface of the structure, the body comprising a device Forming a component protrusion formed in a rear body and a front cover, and coupling a recess formed in the rear body and the front cover; and a plate body contacting in an appropriate position And to the surface of the structure, and having a mounting opening for mounting the body from the side of the board body, the board body including an engaging receiving member protruding from an inner surface of the opening to contact the outer surface of the body a portion of the rear portion of the protruding fastener; and an engaging pressing member having a engaging surface for engaging a front surface of the engaging convex portion, the fixing convex portion protruding from a portion of the outer surface and spanning The mounting opening has elasticity in the inner direction of the table. With the above configuration, the body and the outer cover are supported by the plate body to receive the pressing member, and are supported in a front-rear direction. Due to the heat collection of the material, if one of the assembly protrusions and recesses of the main body and the outer cover is coupled to each other 4

Γ 278160 When the rupture or coupling force is weak, the cover and the body are in a coupled state by the plate body. As a result, materials having significantly different heat shrinkage rates can be selected for the body and the outer cover, thus increasing the degree of freedom for selecting materials. Preferably, the body is made of a thermoplastic resin and the outer cover is made of a thermosetting resin. This configuration is particularly effective in the case where the wiring device is a wall socket. The outer cover of the wall socket may be formed of a high-resistance thermosetting resin, and a relatively complicated body may be formed of a thermoplastic resin. That is, since the outer cover is separated from the body, materials of different shrinkage rates can be used for the outer cover body, respectively. Further, since the body can be formed of a thermoplastic resin, a transparent resin can be used as the body. If the body is made of a transparent resin, it can confirm the state of the internal components in the body of the apparatus. For example, in the case where the external wire is locked by the quick fixing terminal (using the biasing force of the leaf spring), the connection state of the external wire to the quick fixing terminal can be confirmed through the transparent body. Preferably, the wiring device further comprises a trim panel detachably coupled to the front surface of the panel body and having an exposed opening for exposing a front surface of the body. a positioning protrusion protrudes from an outer surface of the device body and an inner surface of the plate body, and is positioned in the other of the outer surface of the device body and the inner surface of the plate body a slot for coupling with the positioning protrusion and restricting movement of the device body in a direction perpendicular to a protruding direction of the positioning protrusion in the opening surface of the mounting opening, the positioning groove being formed in the The symmetrical position in the open surface of the mounting opening in the square. The shape of the holding is not as good as that of the main surface of the ground.

In the above configuration, one of the opening surfaces of the mounting body opening can be made by coupling between the positioning protrusion formed in the main body and the board body and the positioning groove formed at the other body. Relative movement. In this case, since the device is symmetrically extracted with respect to the coupling portion of the positioning protrusion and the positioning groove, if there is a size difference between the exposed opening of the body and the panel body due to dimensional change or heat shrinkage, The size of the gap created between the body and the inner periphery of the exposed opening will be the same, as it prevents damage to its appearance. Meanwhile, in the inner circumference of the mounting opening of the board body, if the surface forming the positioning protrusion or the positioning groove is different from the surface forming the protruding fastener or the fastening protrusion, the board body and the body are The coupling depth can be consistent. Therefore, it can reduce the possibility of separating the apparatus body from the plate body due to the impulse. Preferably, the wiring device further comprises a fascia coupled to the front surface of the panel body and having an exposed opening for revealing a front surface of the body. a positioning protrusion protruding from one of a surface of the device body and an inner surface of the plate body, and in the other of the outer surface of the device body and the inner surface of the plate body, And a plurality of positioning slots formed in a direction for coupling with the positioning protrusion and restricting movement of the apparatus body in the direction, the direction being perpendicular to the positioning protrusion of the opening surface of the mounting opening A sudden direction. With the above configuration, one of the opening surfaces of the mounting opening can be made by the coupling between the positioning projection formed in the main body and the panel body and the positioning groove formed at the other. Relative movement. The limit is the same as the fit and the side is loaded out of the outer number, in the limit of the same 6

At 1278160, since the device is symmetrically withdrawn relative to the coupling portion of the positioning projection and the positioning groove, if there is a dimensional difference between the exposed opening of the body and the panel body due to dimensional change or heat shrinkage, A gap is not formed between the device body and the inner periphery of the exposed opening, thereby preventing damage to the appearance. That is, the relative extraction of the plate body from the body of the device is effected by a plurality of portions which increase the effect of limiting the interaction between the body of the plate and the body of the device. At the same time, in an inner periphery of the mounting opening of the board body, a surface forming the positioning protrusion or the positioning groove is formed different from a surface forming a protruding fastener or a fastening protrusion, and the board body and the device body are The coupling depth can be consistent. Therefore, it is possible to reduce the possibility of separating the apparatus body from the board body due to the impact force. Preferably, the positioning projections are formed at any of the lower body heat shrinkage rates of the apparatus body and the body. With the above configuration, since the heat shrinkage rate of the positioning groove is higher than the positioning projection, when the heat shrinkage occurs, the inner periphery of the positioning groove comes into contact with the positioning projection member, so that the positioning projection member is stably engaged with the positioning groove. Preferably, at least one of the positioning projection and the positioning groove may have a tapered leading edge portion having a width different from the other. With the above configuration, since the leading edge portion is formed, positioning of the positioning groove and the positioning member is easier. Further, the positioning groove and the positioning projection not only make relative expansion/contraction of the main body and the plate body, but also guide the main body when the main body is guided by the mounting opening of the plate body. That is, two functions are available at one location, which can be less expensive to manufacture than installing a separate configuration for each function. If the assembly is limited, the extension of the item is limited to 7

In addition, since the pin receiving spring 14b is to accommodate the flat plug pin and the ball plug pin, the portion holding the ball pin uses a configuration in which the two leaf springs are placed opposite each other. And a flat plug pin is inserted into one of the two springs and between a leaf spring opposite the two springs 9 1278160. The configuration of the pin receiving spring 13a is known in the art. The terminals 13b and 14c function as a lock terminal for which the biasing force for the spring locks the external electric wire, and the external electric wire is introduced into the inside of the apparatus body 1 through the hole 15. The U-shaped locking members 16b of Figures ib and 5 are wide from a rectangular base member i6a and the two pressing members 16c are attached from the other wide shoulders of the base member 16a to the front end of the respective locking member 16b. The feet are opposite. The foot of the lock B is located between the base member 16a of the locking member 16b and the pressing member 10c. The external wires introduced by the terminals 13b and 14c through the wiring receiving holes 15 are inclined from the pressing end to the front end of the member 16b between the locking member 16b and the pressing member 16c, and are inclined toward the pressing member Uc. The utility model becomes a P-knife, and the pressing member 16c has a convex portion which is bent in a middle position between the locking 鸲 and the wiring accommodating hole 5, and is inserted into the device body 1 through the wiring receiving hole 15. It is fitted between the locking member 16b and the pressing member 16c to achieve an electrical connection of 4^. The leading edge of the locking member 16 b is stuck to the outside - preventing the wire from being loosened. As described above, since a base member has two locking members 16b and two pressing members 16c, they can be respectively wired. If the body 10 is made of a transparent resin, it can confirm whether the wiring of the hole 15 inserted into the apparatus body i is properly connected and 14c, which improves the efficiency of the joining work. In the respective terminals 13b and 14c, a release lever 17 14a and 14b is shown in the blade-elastic connection, and the two-edge extension L edge extends, and one leg of the stator 16b is placed in such a manner that the member 16c Front position.

Because > part of the wire, the terminal 13b and the wire, "1 6 a system is connected to the external electrical self-wiring capacity f to the terminal l3b will be inserted into a lock 10 1278160-shaped in the middle of the front-mounted system Elliptical inserts. More flat between 21a. The release lever 17 includes a body 17a having an end exposed through the slit l〇d through the center of the side wall of the body 1〇, as shown in Fig. 1D. The rod body 17a is provided at the other end and has a shaft portion 17b supported in a suitable position of the wood Λ 1 1 〇. The 4th portion of the shaft portion 17b is JL>', and the second portion of the shaft portion 17b is contactable with the two locking members 16b in the terminal 13b or 14c. The through-slit 10d opening in the body 1〇, the external electric wire is connected in the state of the terminal 1 3 b, 1 4 C, when releasing the field 17 ^

When the dry winding portion 1 7 b is rotated (for example, a right release lever 17 will lift x in the counterclockwise direction of FIG. 1b), the front end & force of the locking member 16b causes it to be pressed by the portion L7c leaves the pressing member l6c so that the locked state of the external wire is released to easily draw the external wire from the body 1. The cover 2 is provided with insertion holes 21a, 22a, and 22b which penetrate the outer position at positions corresponding to the pin receiving springs 13a, 14a, and 14b. The opening of the insertion hole 21a has a long rectangular shape in the vertical direction of Fig. 4a, and thus a flat plug is inserted into the hole 21a into the ground. The insertion hole 22a is adapted to accommodate the spherical pin and the flat pin, and the insertion hole 22a - the surface having the opening is formed in a semicircular or semicircular shape. The two insertion holes 22a are disposed in the horizontal direction of Fig. 4a, and the portions facing the insertion holes 22a are formed in a rectangular shape, so that the flat head pins are inserted into the rectangular portions. It is used for accommodating the width of the flat plug/chopper, which is wider than the portion for accommodating the ball plug. Further, the opening of the insertion hole 22b has a rectangular shape for accommodating the connector pin, and is disposed under the insertion hole 11 1278160 in the horizontal direction of Fig. 4a. The insertion hole 22b is displaced obliquely, so that the distance between the lower ends of the insertion holes is shorter than the distance between the upper ends. However, the wall socket of this embodiment includes an outlet formed by the insertion hole 22a and the insertion hole 22b, and an outlet composed of the insertion hole 2 1 a.

As shown in Fig. 1, the sheaths 2 3 a and 2 3 b are provided at the outlet to open and close the insertion holes 21a, 22a and 22b when the holes are not inserted. More specifically, the sheaths 23a and 23b are attached to the respective outlets to close the insertion holes 21a, 22a and 22b of the respective outlets. Further, the sheaths 23a and 23b are pressed in the direction of a closing outlet by the return springs 24a and 24b which are coil springs disposed between the inner periphery of the outer cover 20 and the sheaths 23a and 23b. composition. The outlets are covered by the sheaths 23a and 23b at normal times to prevent foreign objects (i.e., dust) from entering the outlets. When the sheaths 23a and 23b close the outlet, each of the sheaths has a surface which is obliquely inserted into the holes 21a, 22a and 22b. When the flat plug pins and the ball pins are inserted into the insertion holes 21a, 22a, and 22b, the sheaths 23a and 23b are applied to the inclined surface by the flat plug pins and the ball pins. It is opened to resist the biasing force of the return spring. The bottom surface of the outer cover 20 is formed with pressing ribs 25 at portions corresponding to the respective terminals 13b and 14c so that the ribs come into contact with the base members 16a of the respective terminals 13b and 14c, and thus the terminals 13b are prevented. And 14c rises from the body 10. In the case where the body A of the above-mentioned wall socket is attached to a construction surface (for example, a wall), as shown in FIGS. 1 and 5, a plate body B is fixed to the construction surface in a vertical position, and The fascia C is coupled to the panel body 12 1278160 B for surrounding the front surface of the panel body B. The plate body b and the fascia C are a rectangular frame. The plate body B has an opening 31 for mounting the main body a, and the garnish C has an opening 41 for exposing the front side of the main body A. The plaque C is provided with coupling legs (not shown) on one of its rear sides, each of which is inserted into the four coupling holes 30a formed around the board body B. The fascia C is coupled to the panel 'body B by spraying a hook member formed at the front end of the coupling leg to the periphery of the coupling hole 30a. At the same time, at a lower edge of the plate body B, a separating member 30b is extended, and at a lower edge of the garnish C, a separation groove 4b is formed to engage the separating member 30b. In a state in which the fascia c is attached to the slab body B, a tool such as a negative driver can be inserted between the separating member 3 〇b and the separating groove 40b, and the fascia c can be self-applied by using the tool as a lever B separation. Coupling to the plate body B at the time of construction. The body 10 is provided on its two sides with a protruding fastener which protrudes from an outer surface (the outer portion 18 of one of the opening edges of the body 1 。. A convex portion 26 is a part of the two sides of the outer cover 20 (outside single 2 The center of the underarm surface protrudes. The protruding fastener 18 is divided into two parts which are upward and downward in a portion corresponding to 10d. A missing part is formed in the slit of the protruding buckle. 27 is formed in the outer cover 20 corresponding to the protrusion 2 Two or two points. The two sides of the outer cover 20 are adapted to be made to be apart from the notch 27; the rear side corresponds to the rear side of the protruding fastener 18. At the same time, the front side of the fastening knife is tied to a relative position The front side of the rear side of the protruding member 18: 26 is formed by a section 26 such that the protruding dimension toward the rear is smaller. The first sheath W is formed on the upper right portion of the body, and when the outer cover is 13 1278160 At 20 o'clock, with respect to the right side of the outer cover 20, it protrudes more toward the right of the outer cover 20. A second sheath 19b protrudes from a base of the first sheath 19a toward the front side. The outer cover 20 corresponds to the first And a portion of the second sheaths 19a and 19b is provided with a notch 2 8 for mounting a switch. The notch 28 will engage the first and second sheath 19a and 19b. In the state of the cover 10 is coupled with the body 20 lines, notches for mounting the switch 28 is surrounded on its function will now be described hereinafter.

As shown in Fig. 6, the plate body B is a rectangular frame having a pair of left and right mounting frame members 32 and a coupling member 33 for coupling the upper and lower ends of the frame 32. The intermediate portion of the mounting frame 32 in the longitudinal direction (the vertical direction in Fig. 6) is formed with a mounting hole 32a having an elongated shape in the vertical direction. The mounting hole 32a is for accommodating a fixing screw for fixing the plate body B to the structural surface. For example, a box is inserted into the construction surface, and the fixing screw is fixed into a screw hole formed in the case, which fixes the plate body B to the construction surface. At the same time, the coupling member 33 is formed with a biasing hole 34 passing through the coupling member in the horizontal direction. An engaging pressing member 35 is formed between the biasing hole 34 and the mounting opening 31. Therefore, the engaging pressing member 35 has elasticity in the direction of the inner periphery of the vertical mounting opening 31. The engaging members 36 project from the appropriate portions of the right and left inner surfaces of the mounting opening 31. In order to mount the main body A to the board body B, the main body A is inserted into the mounting opening 31 from the front side of the board main body B. When the rear portion of the body 10 is inserted into the mounting opening 31, the rear side of the protruding fastener 18 provided on the body 10 comes into contact with the front surface of the engaging member 36 to restrict the rearward movement of the protruding member 18. At the same time, when the engaging projection 26 is pressed against the engaging pressing member 35, the engaging pressing member 35 is bent outwardly 14 1278160. If the engaging projection 26 and the engaging surface of the engaging surface of the engaging surface are: :: the weight: the - surface to restrict the forward movement of the main body A. More specifically, ° 26 different

In the state of being coupled to the plate body B, the wiring device 2's main body A2 is supported by the engaging member 36 of the plate body B and the engaging members 10 and 10 even if the component projecting surface 20a is for any reason (heat shrinking or,: 35J: The group formed in the assembly _ is loosened, and the body cover 20 is separated. As a result, the body 1 is not the same as the material of the outer cover 20. At the same time, the engaging member 36 is formed, and the T 乂 乂The left side of the body B and the inner side of the right side. The pressing member 35 is formed inside the pressing member 35. Therefore, even if the dimensional tolerance of the engaging member 36β member 36 and the pressing member 35 is due to the plate body 』 and the middle of the ^ ij 芎, so the main body A may still be attached to the plate body B. Therefore, the tolerance range of the dimensional tolerance of the meshing component D and the pressing member 35 < (5) and then increase. If the plaque C is attached to the plate body B, the insert 40c hole 34' protrudes from the slab ', the slave member l and the pressing member 35 does not bend "the lightness of the B-intensity. - If the body A is added As shown in Fig. 6, the plate must be „ ^ 疋 large output 37 is formed from the plate body β of the adjacent and right U holes 32a (four) Η In other words, in the adjacent positioning abutment, a portion of the unshaped engaging member 3 6 on the upper and lower portions 37 of the large output member 37 and a recessed portion are less formed between the positioning projection member 37 and the engaging member 36. As shown in Figures 3 and 4, the positioning grooves 29 coupled to the positioning projections are formed on the left and right sides of the y, cover cover 20. The positioning grooves are formed in an intermediate portion between the upper and lower sides of the body 1. That is, in the main pressure table cover 丨. The white outside is not installed in the middle of the body to the left side of the body 37 29 body 15

1278160 A is attached to the plate body B, and the positioning projections 3 7 and 29 are formed in a position symmetrical with respect to the opening surface of the mounting opening 31. The two sides of the positioning groove 29 are engaged with the protrusions which are divided into two halves. The two halves are formed with a through slit in the body 1 as described above, because the protruding fastener 18 is engaged with the notch 27, and the first sheath 19a and The 19b engagement notch 28 is for mounting a switch which prevents the slit 10a and the positioning groove 29 from expanding in the vertical direction. As described above, the positioning groove 29 and the positioning projection 37 are formed in a position in the vertical direction of the board body B. When the body A is attached to the plate body B as shown in Fig. 7, the apparatus body 1 is contracted in the vertical direction by the function of positioning the positioning groove 29 and the positioning projection 37 as a rest position. Therefore, when the fascia C is attached to the front side of the body B, the mounting opening 31 of the board body B is perpendicular to the exposed opening 41 of the fascia C. Therefore, even if the size of the apparatus body 1 is changed by heat shrinkage, the gap between the upper and lower edges of the exposed opening 41 and the front of the package 1 are identical to each other. In addition, it can prevent the appearance of the oblique gap from deteriorating in appearance quality. If the gap is weakened by the upper and lower engaging projections 26 or the engaging pressing members 35, the wiring device A may be detached from the board due to a strong impact force or the like. However, since the gap between the upper and lower portions is uniform, the meshing depth of the convex portion 26 and the engaging pressing member 35 cannot be lost, so that they are not easily separated from each other by impact force or the like. The engaging pressing member 35 is provided at its rear portion with a positioning projection corresponding to the two sides 35 of the projection 26. a 10d ° and a second stop of the transverse positioning groove of the engaging pressing member 35 are symmetrical, and when the main expansion portion is connected to the vertical center of the plate, the body is divided by the inclined body. The buckle is 38, and its movement system 16 38 1278160 is limited to the positioning protrusion 38. More specifically, a portion between the pair of positioning projections serves as a positioning groove, and the engaging projection 26 serves as a positioning projection. The snap projection 26 and the positioning projection 38 are formed in a laterally symmetric manner. The left and right gaps are formed uniformly to allow expansion/contraction of the body 1. As shown in Figs. 8 and 9, the positioning projections 37 are formed on the front side thereof, and the leading edge portion 37a has a width which decreases toward the front end thereof. The position of the main body and the plate body B can be aligned with each other by the leading edge portion 37a, which easily achieves the positioning of the positioning groove 29 and the positioning projection 37. Here, the leading edge portion 37a is formed on the positioning projection 37, and the positioning groove 29 and the positioning projection 37 not only restrict the relative expansion/contraction of the main body A and the panel body B, but also the main body A is introduced into the mounting opening 31 of the panel body B. When the body A is guided. It reduces costs compared to each functional ampoule-separate configuration. As shown in Fig. 9, in the state in which the engaging convex portion 26 of the main body a is in contact with the front surface (the upper surface of Fig. 9) of the spray pressing member 35 of the plate body B, the positioning groove 29 is suitable. The edge &quot;blade 37a formed at the front end of the positioning projection 37 is inserted into the positioning groove 29. More specifically, the locating groove 29 is advantageously extended from the rear surface of the outer cover 20. In the shape L in which the main body a is in contact with the plate body, the 'clamping groove 209 is temporarily coupled to the positioning protrusion. </ RTI> The position of the body &amp; main body A with respect to the plate body B is easily attained. In this embodiment, although The plate body B is each of the left and right sides into a dog canopy 37 (as shown in Fig. 10), and the positioning protrusions 37 are formed at a plurality of positions in at least the side.

The positioning projections 3 7 are formed at a center point of a symmetrical position in a vertical direction, and the other positioning projections 7 7 are formed at the lower end, and are located to the right of the positioning protrusions 37 on the left side. The main body A is formed with a positioning groove 29 at a portion corresponding to the respective positioning projections 37. As shown in Fig. 10, the positioning projections 37 are formed in portions on one side. Since the expansion/contraction of the apparatus body 1 toward the side is restricted in some portions, the effect of restricting the expansion/contraction of the main body A and the plate body B is improved. Meanwhile, in the case where the positioning projections 37 are formed in a plurality of portions, the efficiency of restricting expansion/contraction of the apparatus body 1 is high. Therefore, if the distribution of the positioning projections 37 is uneven, the effect of reducing the variation of the gap between the main body A and the fascia C exposed opening 41 can be obtained by forming the positioning projections 37 at appropriate portions. However, in order to further enhance the effect, it is preferable to form a positioning projection at a symmetrical position in the extending direction of the side on which the expansion/contraction of the apparatus body 1 is restricted. In this embodiment, although the positioning groove 29 is formed in the main body A, and the positioning protrusion 37 is formed on the board body B, a positioning protrusion may be formed on the main body A, and a positioning groove may be formed on the board body. B. The heat shrinkage ratio of the main body A and the plate body B determines that the positioning projections 37 are formed on the main body A or the plate main body B. Preferably, the positioning projections 37 are formed in a portion where the heat shrinkage is low. In other words, when heat shrinkage occurs, if the heat shrinkage ratio of the positioning groove 29 is higher than the positioning projection 37, the inner periphery of the positioning groove 29 contacts the positioning projection 3, and thus the positioning projection 37 securely engages the positioning groove 29 . In this embodiment, although the leading edge portion 37a is formed in the positioning projection 37, a leading edge portion may be at the positioning groove 29, or 18 1278160 may be formed at both the positioning projection 37 and the positioning groove 29. .

When a portion of the wall socket is modified, a wall socket having a built-in switch can be formed, as shown in FIG. In the specific embodiment shown in Fig. 11, a handle mount 19c extending to the right side is provided as an alternative specific to the first and second sheaths 19a and 19b of the body 10 shown in Fig. 5. Example. A slab-shaped handle 50 is attached to the handle mount 19c. The handle 50 has a manually operated operator 50a at its right end and a shaft 50b on the left side of the operator 50a. The operator 50a is in contact with the handle mount 19c on a rear surface thereof so that the operator can be rotated up and down. The shaft 5 Ob passes through the opening 2 8 for mounting the switch, and the shaft projection 50c formed on the front surface of the shaft 50b engages a notch 28 formed at the front edge of the opening 28 for the shaft for mounting a switch to The shaft pivots about the shaft projection 5 0 c. Although the voltage member 14 housed in the right voltage compartment 12c is composed of two pin receiving springs 14a and 14b connected to the terminal 14c (as shown in FIG. 5), the concrete implementation in FIG. In the example, the two pin receiving springs 14a and 14b are connected through a conductive plate 51. The terminal 14c forms a stationary contact 52 adjacent a portion of the handle mount 19c. The terminal 14c is connected to a support plate 53. One end of the support plate 53 is in contact with an edge of a switching portion 55 which forms a movable contact member 54 that is in contact with and separated from the stationary contact member 52. The switching portion 5 5 is pivotable about an edge of the switching portion between a position where the stationary contact 52 contacts the movable contact 54 and a position where the stationary contact 52 is separated from the movable contact 54. The pivoting range of the switching portion 5 5 is defined by the internal shape of the body 1 〇. 19 Ϊ 278160 The return spring 56 consisting of a spiral sheet # Λ and red c ping is held between the glaze 5 〇 b of the handle 50 and the cut portion. The return spring 56 is extended and received by the swing handle 50#. More specifically, the handle 50 is swayed in the summer by the two 詈pE|'s defined by the handle mount i 9c. When the handle 50 is swung from one position to the other - 罝, the resilience is softened and the maximum compression is achieved at the center position. If the handle: moves beyond this position, the return spring 56 will be abruptly extracted, so the position of the part 5 5 will be reversed. The above operation is similar to a seesaw switch. % The above configuration, if the operation of the swinging handle 50 is performed, the switching portion 35 will; I: the zone chain ~ symbol ' and the movable contact 54 is separated from the stationary contact member 52, so that the member can accommodate the pin in the pinch." A circuit between the pages 14a and 14b and the terminal 14c can be switched. As can be seen from the description of the mask, since the wall socket shown in Fig. 5 is used, the outer cover 2 can be used in common regardless of whether or not the switch is present. 4. The plaque corresponding to the wall socket having the built-in switch shown in Fig. 11 is continuously formed with a notch 42 for exposing the right-t-^^j. _ knife handle 50 of the exposed opening 41. The exposed notches 42 are formed in a portion that does not overlap the rectangular opening ^ as shown in Fig. 12a. In general, since the width of the housing body 1 of the wall socket is wider than the plug to be connected, by mounting the handle 50 on the side of the housing 20 as described above, when the plug D is connected, it is operable: the handle 5 is not Overlap with plug ,, as shown in Figure 12b. The teachings of the present invention are applicable to any wiring split having other functions, wherein a device body of a body is coupled to a component concave surface by a component convex surface and coupled by a separated body and housing coupling. Although the present invention is described with reference to a wall socket, one of the devices of the present invention is provided with two outlets' but is not limited thereto.
