BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of a joint tap, a power tap, and a power tap set according to the present invention will be described below with reference to the drawings.

1. Schematic Configuration of Power Tap Set First, the schematic configuration of the power tap set according to the present embodiment will be described with reference to FIGS. 1 and 3. FIG. FIG. 1 is a perspective view explaining the power tap set according to the present embodiment (in the case of 2 ports), and FIG. 3 is a perspective view explaining how to attach the power tap included in the power tap set to a predetermined place (in the case of 3 ports).

As shown in FIG. 1, the power tap set 1 of this embodiment includes an extension cord type power tap 10, which is a type of joint tap. This power tap 10 has an outlet module 14 with a power cord 12 as a connector module, and an outlet plug 11 provided on the tip side of the power cord 12 . The power tap 10 shown in FIG. 1 is provided with an outlet module 14' without a power cord as another connector module.

Further, the power tap set 1 is provided with a pair of fixing holders 17, 17 for detachably attaching the power tap 10 to a predetermined place, as shown in FIG. The pair of fixed holders 17, 17 are preliminarily fixed with bolts at predetermined intervals, for example, on the underside of the top plate of a desk.

The pair of fixed holders 17, 17 are members having a bilaterally symmetrical shape, and each fixed holder 17 is provided with bolt holes 17C, 17C for inserting bolts from the lower side toward a predetermined location (back of the top plate).

The specifications of the power tap 10 are, for example, a rated voltage of 125 V, a rated current of 15 A, a length of the power cord 12 of 3 m, and a total of 1500 W, but the specifications are not limited to these.

2. Combination of Number and Type of Connector Modules Next, the combination of the number and type of connector modules will be described with reference to FIGS. FIG. 2 is a perspective view illustrating a power tap set including an outlet module and a USB module as connector modules (in the case of 2 ports), and FIGS.

As shown in FIGS. 1, 2, and 6, the combination of the number and types of connector modules accommodated in the power strip 10 can be arbitrarily selected. Therefore, for example, the manufacturer can customize the power strip 10 by appropriately selecting combinations of the number and types of power strips 10 according to the destination of the power strip set 1 and the user's request.

For example, the power strip 10 accommodates at least two or more connector modules selected from various connector modules such as an outlet module 14, a USB module 15, a LAN connector module, and an HDMI (registered trademark) connector module. Needless to say, the types of connector modules are not necessarily limited to these, and it is possible to select a connector module having an appropriate connector.

Also, the USB module can be selected from two types, for example, a connector for USB charging (requires power supply) and a connector for USB connection (no power supply required). Furthermore, the USB module can be selected from two types, for example, a USB-C module conforming to the USB-C standard and a USB 3.0 module conforming to the USB 3.0 standard.

In the example of FIG. 1, the combination of types of connector modules is a combination of outlet modules 14, but it is also possible to combine outlet modules 14 and USB modules 15 as shown in FIG. Reference numeral 15A in FIG. 2 is a USB port, and reference numeral 14A in FIG. 2 is a plug insertion port.

In the example of FIG. 1, the number of ports (the number of connector modules) of the power strip 10 is "2", but it can be expanded to "3" or more as shown in FIGS. 6(C) to (F).

In order to make it easier to change (exchange) the number (number of ports) and arrangement of the connector modules accommodated in the power strip 10, it is preferable that at least the width size (the size in the longitudinal direction of the body frame 13 described later) be set in common among various connector modules.

3. Configuration of Power Tap Next, the configuration of the power tap 10 will be described with reference to FIGS. 2, 4, and 5. FIG.
FIG. 2 is a perspective view illustrating a power tap set including an outlet module and a USB module as connector modules (for 2 ports), FIG. 4 is an exploded view of the power tap set 1 (for 2 ports), and FIG. 5 is an exploded view of the power tap set 1 (for 2 ports) viewed from a different viewpoint from FIG. Here, it is assumed that the number of ports of the power strip 10 is "2" as in the example of FIG.

As shown in FIGS. 2, 4, and 5, the power strip 10 includes a body frame 13, a pair of resin end caps 18, 18, and a pair of mounting mechanisms 20, 20. As shown in FIGS.

The body frame 13 is a frame having a substantially U-shaped cross section that houses a plurality of connector modules (here, the outlet module 14 and the USB module 15) side by side. An upper surface portion 13U and a lower surface portion 13D are provided so as to extend in a cantilever manner from the upper edge and lower edge of the back surface portion 13B of the body frame 13. The back surface portion 13B is provided with a plurality of openings 13F and 13F (FIG. 5) of equal size and at equal intervals for exposing the respective insertion openings or connection ends of the plurality of connector modules (here, the outlet module 14 and the USB module 15) housed in the body frame 13. Of the two openings 13F, 13F shown in FIG. 5, the left opening 13F is an opening for exposing the connection end from the outlet module 14 to the power cord 12 (for inserting the power cord 12), and the right opening 13F is an opening for exposing the receptacle (USB port) 15A on the back side of the USB module 15. Therefore, in the power strip 10 of the present embodiment, the number of connector modules (the number of ports) can be increased or decreased as appropriate simply by changing the length of the body frame 13 and the number of openings 13F in the direction in which the connector modules (outlet module 14, USB module 15, etc.) are adjacent to each other.

The pair of end caps 18, 18 are caps that are fitted to both end sides of the body frame 13 in order to sandwich a plurality of connector modules (here, the outlet module 14 and the USB module 15) from both sides. The pair of end caps 18, 18 have a symmetrical shape.

A pair of mounting mechanisms 20 is a mechanism provided on a pair of end caps 18, 18 for detachably mounting the power tap 10 to a pair of fixed holders 17, 17 (FIG. 3) fixed in advance at predetermined locations. The pair of mounting mechanisms 20, 20 also have a symmetrical shape.

The housings of the connector modules (here, the outlet module 14 and the USB module 15), the end caps 18, 18, the mounting mechanisms 20, 20, and the fixed holders 17, 17 are made of resin, for example, and the body frame 13 is made of metal, for example. In particular, the body frame 13 can be manufactured by extrusion molding a metal plate such as aluminum, and the body frame 13 having an appropriate length can be easily manufactured by extrusion molding. By forming the body frame 13 from metal in this way, it is possible to easily cope with an increase or decrease in the number of connector modules (the number of ports). For example, by preparing in advance a long body frame in which a large number of openings 13F are formed at equal intervals, and cutting it appropriately, it is possible to immediately prepare the body frames 13 of the required number. Moreover, if the cut portions (edges) of the metal body frame 13 are covered with resin end caps 18, 18, there is an advantage that safety can be ensured without requiring time for processing the edges. It goes without saying that the material forming each member is an example, and an appropriate material may be adopted.

4. Configuration of One-Touch Mounting Mechanism Next, the configuration of the pair of mounting mechanisms 20 will be described with reference to FIGS. 4 and 5. FIG. Here, the configuration of one mounting mechanism 20 will be described, and the description of the configuration of the other mounting mechanism 20 will be omitted.

As shown in FIGS. 4 and 5, the attachment mechanism 20 includes a guide portion 18A and elastic members 20B. The guide portion 18A is a groove portion provided on the upper surface side of the end cap 18 for slidably inserting the fixed holder 17 (FIG. 3), and the elastic member 20B is an elastic member disposed inside the end cap 18, formed in a substantially U-shaped cross section, and biased in a direction to separate the open end side. An engagement projection 20C is formed on one outer surface located on the open end side of the elastic member 20B.

The user grasps the power tap 10 and slides the guide portion 18A into the fixed holder 17 fixed at a predetermined place while moving it in the direction D1 in FIG. As the slide is inserted, the upper surface of the elastic member 20B is gradually pressed downward, but when the insertion amount exceeds a certain amount, the engaging projection 20C is engaged with the engaged portion 17A provided on the fixed holder 17 by the biasing force of the elastic member 20B, and as a result, the power strip 10 is arranged and fixed at a predetermined location (one-touch mounting mechanism).

When the user pushes down the engaging projection 20C against the biasing force of the elastic member 20B (direction D2 in FIG. 4) while the power strip 10 is fixed to the fixed holder 17 (FIG. 3), the engaging projection 20C is disengaged from the engaged portion 17A, so that the power strip 10 can be removed from the predetermined place.

5. Slide Structure for Tap Assembly Next, a slide structure for tap assembly will be described with reference to FIGS. 4 and 5. FIG.
As shown in FIGS. 4 and 5, guide rail portions 13E and 13E are provided on the opposing inner surfaces of the upper surface portion 13U and the lower surface portion 13D of the body frame 13, respectively, in the direction in which a plurality of connector modules (here, the outlet module 14 and the USB module 15) are adjacent to each other. For example, the guide rail portions 13E, 13E are made of the same material as the body frame 13, and are formed integrally with the body frame 13. As shown in FIG. Specifically, a convex portion protruding inward is formed on the open end side of the upper surface portion 13U, and a key-shaped concave portion having a substantially J-shaped cross section is formed on the side of the rear surface portion 13B. On the other hand, a key-shaped concave portion having a substantially J-shaped cross section is formed inside the open end side of the lower surface portion 13D, and a convex portion protruding inward is formed on the side of the rear surface portion 13B.

On the other hand, a plurality of connector modules (here, the outlet module 14 and the USB module 15) accommodated in the body frame 13 are provided with convex or concave edge portions E, E that engage with the guide rail portions 13E, 13E, respectively.

Therefore, when assembling the power strip 10 of the present embodiment, the connector modules (here, the outlet module 14 and the USB module 15) are sequentially slid and inserted (loaded) while the edges E, E of the plurality of connector modules (here, the outlet module 14 and the USB module 15) are aligned with the guide rails 13E, 13E. can be placed.

Moreover, if the guide rails 13E, 13E are provided on the upper surface portion 13U and the lower surface portion 13D of the main body frame 13, the rigidity of the main body frame 13 can be increased. Therefore, even if the number of connector modules is large (FIGS. 6E and 6F), there is an effect that the inconvenience of warping of the main body frame 13 can be avoided.

Furthermore, in the power strip 10 of the present embodiment, as described above, the guide rail portion 13E on the upper surface side and the guide rail portion 13E on the lower surface side are set to have a vertically asymmetric shape, and correspondingly, the upper and lower surface sides of the edge portions E, E of the connector module (here, the outlet module 14 and the USB module 15) are also set to have a similarly vertically asymmetric shape. This prevents the connector modules (here, the outlet module 14 and the USB module 15) from being inserted into the body frame 13 in an upside-down posture. Therefore, the probability that the manufacturer fails to assemble the power strip 10 can be reduced, and the efficiency of manufacturing can be improved.

6. Breakage Prevention Structure Next, a breakage prevention structure for the power cord will be described with reference to FIGS. 4 and 5. FIG.
As described above, in the power strip 10 of this embodiment, one of the plurality of connector modules (the outlet module 14 and the USB module 15 here) is the outlet module 14 with the power cord 12 .

In the power strip 10 of the present embodiment, a retaining mechanism 19 for preventing disconnection of the connecting end from the outlet module 14 to the power cord 12 is arranged inside the opening 13F corresponding to the outlet module 14.

The retainer mechanism 19 includes retainer members 19A and holding members 19B that clamp the proximal end of the power cord 12 from both left and right sides. The retention member 19A, which is one of the members, has a holding portion 19C having a substantially U-shaped cross section for holding the power cord 12 extending from the outlet module 14. As shown in FIG. The holding member 19B, which is the other member, is a holding member attached to the retaining member 19A, and presses and fixes the power cord 12 held by the retaining portion 19C with a hook 19D that engages with the retaining member 19A.

Therefore, when the power strip 10 is attached to a predetermined place and the outlet plug 11 is connected to the commercial power supply, even if the power cord 12 is caught by a leg or the like and the power cord 12 is pulled, the connection end between the power cord 12 and the outlet module 14 can be prevented from breaking.

7. Effects of Embodiment As described above, the extension cord type power tap 10 according to the present embodiment includes a body frame 13 that accommodates a plurality of connector modules (here, the outlet module 14 and the USB module 15) side by side, a pair of end caps 18, 18 that are attached to both ends of the body frame so as to sandwich the plurality of connector modules (here, the outlet module 14 and the USB module 15) housed in the body frame 13, and a pair of fixing holders 17 that are fixed in advance at predetermined locations. Since a pair of mounting mechanisms 20, 20 provided on the pair of end caps 18, 18 are provided in order to detachably mount the joint tap to 17, the pair of end caps 18, 18 have the function of clamping the plurality of connector modules 14, 15 from both sides and the function of fixing the power tap 10 to the pair of fixed holders 17, 17. Therefore, basically, by appropriately changing the length of the body frame 13 in the direction in which the plurality of connector modules (here, the outlet module 14 and the USB module 15) are adjacent to each other, it is possible to increase or decrease the number (number of ports) of the plurality of connector modules, and it is not necessary to change the design of the pair of end caps 18, 18 and the pair of mounting mechanisms 20. Therefore, the power strip 10 according to the present embodiment can be detachably attached to a predetermined place, and it is easy to customize the combination of the number (number of ports) and types of connector modules.
Since the power tap set 1 according to the present embodiment uses the power tap 10 according to the present invention, the same effect as the power tap 10 is obtained.

8. Variations of Connector Module Finally, some variations of the connector module will be described with reference to FIG. FIGS. 6A to 6F are diagrams listing variations of the connector modules accommodated in the power tap 10 (for 2 to 4 ports).

In any of the above-described embodiments, the combination of connector modules housed in the power tap 10 can be variously changed, for example, any one of FIGS. 6A to 6F can be used.

6A is a combination of two outlet modules similar to the example of FIG. 1, FIG. 6B is a combination of one outlet module and one USB-C module similar to the example of FIG. 2, FIG. 6C is a combination of two outlet modules and one USB-C module, FIG. .0 module, and Figure 6(F) is a combination of one outlet module and two USB-C modules.

Further, in any of the embodiments described above, a joint tap (that is, the power strip 10) including at least one outlet module has been described, but the joint tap may not include an outlet module. For example, at least two modules selected from a USB module, a LAN connector module, and an HDMI (registered trademark) connector module may be accommodated in the body frame 13 .

In any of the above-described embodiments, when two or more outlet modules 14 are accommodated in the body frame 13 (for example, FIGS. 6C, 6E, and 6F), any one outlet module is an outlet module with a power cord, and power is supplied to the other outlet modules via the outlet modules with power cords. In that case, since it is not necessary to expose the rear side of the other outlet modules, for example, a resin cover (blindfold) may be fitted to the corresponding opening of the body frame 13 .
