Description

  The present invention relates to a technique for a wiring device having a face-to-face insertion port. In particular, the present invention relates to a structure of a blade receiving bracket provided in a small wiring device (also referred to as a microtap).

  2. Description of the Related Art A wiring device having a plurality of outlet portions (insertion ports) is known so that power can be supplied to a plurality of electrical devices from a single outlet port provided on a wall or the like. A power plug of the electric device is inserted into the outlet portion, and the electric device and the power source are electrically connected via the wiring device.

  For example, there is a wiring device having a facing insertion port configured to be able to insert a power plug from one direction and a direction opposite to the one direction (see Patent Document 1 and Patent Document 2). In the wiring device having such a face-to-face insertion port, each blade receiving bracket (plug receiver) is electrically connected inside the housing, and is configured to be able to supply power from a power source to each electric device. ing.

Japanese Patent Laid-Open No. 08-115774 JP 2005-183323 A

  However, in the configuration of the blade receptacle of the face-to-face insertion port disclosed in Patent Documents 1 and 2, the housing portion that accommodates the blade fitting is reduced in size while maintaining the configuration of the face-to-face insertion port. In other words, the problem remains that it is difficult to downsize the product. For example, in order to reduce the size of the product, there is a method in which the blade bracket is made into an integrated structure with a two-piece structure in a wiring device provided with a face-to-face insertion port. In the following, a two-piece integrated blade holder will be described with reference to FIG.

FIG. 6 is a diagram for explaining an example of a two-piece insertion-piece blade bracket that is configured so that plugs can be inserted from both sides. FIG. 6A is a plan view of a two-piece integrated blade holder, and FIG. 6B shows a state where a power plug is inserted from one side of the two-piece blade holder. FIG.
As shown in Fig. 6 (a), the two-piece integrated blade holder has a structure in which the power plug can be inserted from both the left and right sides, and the inserted plug blade can be inserted to the position where it overlaps in the vertical direction. Configured. Thus, it becomes possible to reduce in size the housing | casing itself which accommodates this by setting it as the blade receptacle metal fitting of two places integrated structure. In addition, the two-pointed integrated blade bracket has a structure that limits or fixes the opening distance of the blade bracket by surrounding the outer periphery of the blade bracket with a rib or guide provided inside the downsized housing. Is adopted (see FIG. 6B).

However, in the case of a small-sized wiring apparatus (hereinafter sometimes referred to as a microtap) having a two-point insertion blade bracket configured as described above, the plug is held when the power plug is connected at the same time at two places. There is a tendency to increase power.
In addition, there remains a problem that it is difficult to insert the power plug into the other insertion port facing the power supply plug while the power plug is inserted into the insertion port on one side. This is because, as shown in FIG. 6B, the distance B between the metal fitting center part A and the rib changes by inserting the power plug on one side, and the relative positional relationship between the insertion port and the metal fitting center part A. This is because a deviation occurs in the case.

  The main object of the present invention is to provide a wiring device that can prevent the occurrence of a phenomenon in which a power plug is difficult to be inserted or unnecessarily difficult to be removed in a wiring device having a face-to-face insertion port. Let it be an issue.

The present invention is a wiring device configured to be able to insert a power plug from one direction and a direction opposite to the one direction, and a plurality of insertion ports for inserting the power plug are formed.

[Example Embodiment]
FIG. 1 is a diagram for explaining an example of a configuration of a micro tap according to the present embodiment. FIG. 1A is a perspective view showing an appearance of a microtap, and FIG. 2B is a schematic diagram for explaining a structure for fixing a blade bracket to be described later inside the housing. FIG. 1C is a diagram showing a specific example of the structure inside the housing.

A microtap 10 shown in FIG. 1A includes a housing 100, and an outlet portion formed so that a power plug can be inserted from one direction of the housing 10 and a direction opposite to the one direction. It has a plug blade 102 to be inserted into a mouth 101 and a power source (not shown).
The housing 100 is configured to hold a blade bracket to be described later. For example, in order to facilitate the attachment of a blade bracket to be described later, an upper part (for example, an upper casing 100a shown in FIG. 1B) and a lower part ( For example, it is configured to be separable from the lower casing 100b) shown in FIG. In addition, the upper part and lower part which comprise a housing | casing are joined via the screw | thread 103 grade | etc.,. Further, the plug blade 102 and the blade bracket are electrically connected inside the housing 100.

The insertion port 101 is formed on both side surfaces of the housing 100 as described above, and a power plug (hereinafter referred to as a plug) of an electric device is inserted therein. Moreover, the insertion port 101 and the blade bracket form an outlet portion on each surface.
The plug blade 102 supplies power from the power source to the outlet portion while being plugged into the power source. That is, power from the power source is supplied to the electrical device connected to the outlet through the micro tap 10 connected to the power source.

  In addition, locking portions 201, 202, 203, and 204 are formed in the upper housing 100a and the lower housing 100b, respectively, for fixing the blade brackets inside the housing. Details will be described later. In addition, the arrow shown in FIG.1 (b), (c) represents the insertion direction of the power plug of the electric equipment inserted from the insertion port 101. FIG.

FIG. 2 is a view for explaining an example of the blade bracket that constitutes the outlet portion of the microtap 10. FIG. 2A is a side view of the blade receiving bracket 200 having a two-point insertion integrated structure, and FIG. 2B is a plan view thereof.
The blade bracket 200 is configured to be connected to plug blades of power plugs of different electrical devices on both sides of the bracket center A as a reference. Specifically, the other electrical plug that is electrically connected to one plug blade of the power plug of the electrical device to be inserted into the outlet portion on one side of the micro tap 10 and that is inserted into the other outlet portion facing it. It is also electrically connected to one plug blade of the power plug of the device.
Further, the plug blade inserted from both directions is configured to be inserted to a position where it overlaps in the vertical direction with respect to the metal fitting central portion A of the blade receiving metal fitting 200. Such a structure of the blade bracket 200 is referred to as a two-piece insertion integrated structure. Thus, by making the blade bracket 200 into a two-piece integrated blade bracket, it is possible to reduce the size of the housing 100 itself that accommodates it.
In addition, since two electric devices are connected at the maximum in the micro tap 10, two blade receiving brackets 200 are provided inside the housing 100 of the micro tap 10. In addition, the number of blade brackets 200 can be arbitrarily set according to the number of connectable electrical devices.

  Further, the inserted plug blade is clamped at a predetermined pressure by the metal fitting center portion A and the pinching portion 200a that swings in accordance with the thickness of the plug blade that is formed opposite to the metal fitting center portion A. Retained. The force for holding the plug blade is set so that the inserted power plug does not easily fall off the micro tap 10 in consideration of safety.

Here, the relationship between the blade bracket 200 and the locking portions 201, 202, 203, and 204 provided in the housing 100 will be described with reference to FIG.
As shown in FIGS. 2 (c) and 2 (d), the blade receiving bracket 200 is formed with a portion (fixed portion) formed so as to be fitted to each locking portion provided in the housing 100. In addition, each fixing portion (201a to 204a) constitutes a positioning mechanism that defines the relative position of the blade bracket 200 with respect to the housing 100 and the insertion port 101 together with each locking portion (201 to 204).

  This positioning mechanism prevents the relative positional relationship between the other insertion port and the metal fitting central portion A that face each other when the power plug is inserted on one side from occurring. That is, even when the power plug of the electrical device is inserted / removed, the positioning mechanism does not change the relative positional relationship of the metal fitting center part A with respect to the housing 100 and the insertion port 101, and as a result, the power plug becomes difficult to insert. Moreover, it is possible to prevent the occurrence of a phenomenon that makes it difficult to remove more than necessary.

  When assembling the micro tap 10, that is, when attaching the blade bracket 200 to the housing 100, the fixing portion 201 a of the blade bracket 200 is fitted into the locking portion 201 of the housing 100. Further, the fixing portion 202 a of the blade bracket 200 is fitted into the locking portion 202 of the housing 100. Further, the fixing portion 203 a of the blade bracket 200 is fitted into the locking portion 203 of the housing 100. Further, the fixing portion 204 a of the blade bracket 200 is fitted into the locking portion 204 of the housing 100. In this way, the blade bracket 200 is provided inside the housing 100.

  Even when the plurality of blade brackets 200 are sandwiched between the upper housing 100a and the lower housing 100b, the fixing portions (201a to 204a) and the locking portions (201 to 204) constituting the positioning mechanism. ) Can define the relative positional relationship between the metal fitting central part A of each blade receiving metal fitting 200 and the insertion port 101.

  In addition, when the blade bracket 200 is formed by bending, the fixing portions 201a and 203a shown in FIGS. 2C and 2B connect the bracket center portion A and the sandwiching portions 200a provided on both sides thereof. It becomes a bent part. That is, in the blade receiving bracket 200 described so far, the manufacturing process is simplified by forming it by bending, and the bending portion at that time functions as a positioning mechanism, thereby reducing the manufacturing cost of the micro tap 10. A dramatic improvement in user experience can be achieved.

FIG. 3 is a view for explaining another example of the blade bracket described in FIG. 2. Note that the difference from the blade bracket 200 described in FIG. 2 is the shape of each fixing portion.
FIG. 3A is a side view of the blade receiving bracket 300 having a two-point insertion integrated structure, and FIG. 3B is a plan view thereof. The plug blade of the electric device inserted into the blade bracket 300 is held at the blade bracket 300 by a predetermined pressure by the bracket center portion A and the clamping portion 300a that swings according to the thickness of the plug blade. Is done.

As shown in FIGS. 3C and 3D, the blade receiving bracket 300 is formed with a portion (fixed portion) that is locked to each locking portion provided in the housing 100. Each fixing portion (301 a to 304 a) constitutes a positioning mechanism that determines a relative position with respect to the housing 100 and the insertion port 101.
In this case, each locking portion of the housing 100 (upper housing 100a and lower housing 100b) is formed in accordance with the shape of each fixing portion (301a to 304a) of the blade bracket 300.

  In the blade bracket 300, the bending process can be simplified as compared with the blade bracket 200 while having a positioning mechanism. Therefore, the manufacturing cost of the micro tap 10 can be further reduced.

  FIG. 4 is a view for explaining another example of the blade bracket described in FIGS. Note that the difference between the blade bracket 200 described with reference to FIG. 2 and the blade bracket 300 described with reference to FIG. 3 is that the blade bracket 400 forms a two-piece integrated structure using a plurality of parts. , The shape and number of each fixing portion. In addition, the blade bracket 400 has a relatively strong advantage as compared with the other.

4 (a) and 4 (b) show the components of the blade bracket 400 shown in FIGS. 4 (c) and 4 (d).
The blade bracket 400 is formed to include a blade bracket component 400a (FIG. 4A) formed including the metal center A and the clamping portion 410a, and the metal center A and the clamping portion 410b. The blade receiving bracket part 400b (FIG. 4B) is included. Further, the blade receiving bracket part 400a and the blade receiving bracket part 400b are joined via the caulking member 402 with the respective metal center portions A back to back (see FIG. 4C).

In the blade bracket 400, as shown in FIGS. 4 (e) and 4 (f), the portions (fixed portions) that are locked to the respective locking portions provided in the housing 100 in the blade bracket components 400a and 400b, respectively. Is formed. That is, the blade bracket 400 has a fixing portion composed of fixing portions 401a, 401b, 403a, 403b, 405a, and 405b. Each fixing portion constitutes a positioning mechanism that determines a relative position with respect to the housing 100 and the insertion port 101.
In this case, each locking portion of the housing 100 (the upper housing 100a and the lower housing 100b) is formed in accordance with the shape of each fixing portion of the blade bracket 300. Moreover, although the fixing | fixed part 405a, b is combining the part formed in the blade bracket component 400a, and the part formed in the blade bracket component 400b as one fixed part, it is not restricted to this.

In the blade receiving bracket 400, the respective metal center portions A are joined back to back, and are in a so-called two-ply state. Therefore, it is possible to improve the strength of the blade bracket alone.
Further, since the relative positional relationship between the metal fitting center portion A of the blade receiving metal fitting 400 and the insertion port 101 is defined via the total of five fixing portions of the blade receiving metal fitting 400, it is difficult to insert the power plug. In addition, it is possible to more reliably prevent the phenomenon that it is difficult to remove more than necessary.

FIG. 5A is a view for explaining an example of an assembly of the blade bracket 400.
For example, the plug blades of the micro tap 10 are configured as plug blades 410 and 411 as shown in FIG. 5A, and two blade receiving brackets 400 are arranged in accordance with the distance between the pair of plug blades of the power plug. These are connected to the plug blades 410 and 411 through the crimping member 402. If the blade holder 400 is assembled in this manner and then disposed in the housing 100, the assembly of the micro tap 10 becomes easier.

  Further, as shown in FIG. 5B, the micro tap 10 can be configured as a micro tap 50 having a USB (Universal Serial Bus) port 501.

As described above, in the micro tap 10 according to the present embodiment, each fixing portion formed on the blade bracket constitutes a positioning mechanism that determines a relative position with respect to the housing 100 and the insertion port 101.
Thereby, even if it is a wiring appliance which has a facing type insertion port, generation | occurrence | production of the phenomenon that it becomes difficult to insert a power plug or it becomes difficult to remove more than necessary can be prevented.
In addition, since the insertion and removal of the power plug of the electric device is stable, it is possible to effectively prevent the device from being damaged by applying an excessive force or an accident due to a conduction failure due to the deformation of the blade bracket. Further, it is possible to provide a small wiring apparatus that is small in size and stable in quality.

  The embodiment described above is for explaining the present invention more specifically, and the scope of the present invention is not limited to these examples.
