Embodiments of the invention will be described with reference to the drawings.

In FIGS. 1 to 6 of the drawings, reference numeral 1A denotes a wiring connection device that includes an outlet for connecting a power cord and is attached by fitting into an attachment hole. Similarly, reference numeral 1B designates a wiring connection device that includes a connector for connecting cables such as a USB cable and is attached by fitting into an attachment hole. Each of wiring connection devices 1A and 1B corresponds to an embodiment of the invention. Although not shown, a wiring connection device according to an embodiment of the invention may have one outlet and one USB connector. The number of outlets and connectors is not limited to two.

Although the wiring connection devices 1A and 1B have different electrical interfaces, they have the same mechanism for fitting into the mounting holes.

For convenience of explanation, it is assumed that the front faces of the wiring connection devices 1A and 1B are the faces where the outlets and connectors appear. This is the surface exposed on the top plate of the desk in the attached state. The front side is the front side, and the side opposite to the front side is the back side. The direction in which the wiring connection devices 1A and 1B are inserted into the mounting holes is the direction that vertically penetrates the front view and goes from the front to the back.

Wiring connection devices 1A and 1B according to the embodiments of the present invention each include a trunk portion 11, a flange portion 12 provided on the front surface of the trunk portion 11, and two facing side surfaces of the trunk portion 11, respectively. It has protrusions 13 a and 13 b provided, and an outlet CON and/or a connector CN attached to the front surface of the body portion 11 . The protrusions 13a and 13b function as claws for attachment.

The protrusions provided on the two opposing side surfaces include first protrusions 13a and second protrusions 13b provided in tandem in the insertion direction. The trunk portion 11 has a rectangular shape when viewed from the back, and protrusions 13a and 13b are provided on the short sides thereof.

The wiring connection devices 1A and 1B are fitted into attachment holes (FIGS. 7B and 8B) configured to be larger than the body portion 11 and smaller than the flange portion 12. As shown in FIG.

When the trunk 11 and the projections 13a and 13b are inserted into the mounting holes and the rear surface of the flange 12 is in contact with the front surface (surface) of the top plate (mounted member) of the mounting holes, the projections 13a and 13b are inserted into the mounting holes. abut (contact) the side of the As a result, the wiring connection devices 1A and 1B are fitted into the mounting holes (FIGS. 7(a), 8(a) and 8(c)).

When the member to be mounted in the mounting hole is thin, the first protrusion 13a is fitted in the mounting hole by coming into contact with the member to be mounted in the mounting hole. The second protrusion 13b is not in contact with the side surface (Fig. 8).

When the member to be mounted in the mounting hole is thick, both the first projection 13a and the second projection 13b come into contact with the side surface of the member to be mounted in the mounting hole, thereby fitting into the mounting hole (FIG. 7). .

Groove portions 11a are provided on the left and right side surfaces of the body portion 11 (surfaces on which the protrusions 13a and 13b are not provided). The groove portion 11a is for preventing the center deviation from occurring when the wiring connection device is attached to the mounting hole. By meshing, it is possible to prevent the wiring connection device from coming off due to unintentional slippage.

Details of the protrusions 13a and 13b will be described with reference to FIG.

The protrusions 13a and 13b are integrally formed with the trunk portion 11 by injection molding, for example. Both of the projections 13a and 13b are branch-shaped members that protrude from the upper and lower surfaces of the body portion 11 in the front direction (the collar portion 12). It is flexible and bends when a force is applied to its tip in the direction of the trunk 11 . When it comes into contact with the side surface of the mounting member of the mounting hole (the side surface of the mounting hole of the top plate), it bends and engages with the side surface of the mounting member due to its reaction.

The first projection 13a on the front (flange 12) side roughly includes a tip portion 13a1, an intermediate portion 13a2, and a bent portion 13a3. The tip portion 13a1 widens slightly outward (in the vertical direction). The intermediate portion 13 a 2 is parallel to the body portion 11 . The bent portion 13 a 3 forms an arc of about 90 degrees to 180 degrees, and the other end is joined to the upper and lower surfaces of the trunk portion 11 . The bent portion is mainly the bent portion 13a3.

The second protrusion 13b on the back side roughly includes a tip portion 13b1, a claw portion 13b2, an intermediate portion 13b3, and a bent portion 13b4. The tip portion 13b1 is parallel to the trunk portion 11 unlike the tip portion 13a1. The claw portion 13b2 has a substantially wedge shape. The intermediate portion 13b3 is parallel to the trunk portion 11. As shown in FIG. The bent portion 13b4 forms an arc of approximately 180 degrees, and the other end is joined to the rear surface of the trunk portion 11. As shown in FIG. The bent portion is mainly the bent portion 13b4. Since the arc portion is long, the bent portion 13b4 can be bent more.

7(a) and 8(a) are cross-sectional views showing a state in which the wiring connection device is attached to the table top plate. The wiring connection device is attached, for example, to the top of a table facing upwards, but in FIGS. is upward).

7(b) and 8(b) show plan views of mounting holes H provided in the top plate of the table or the like for fitting the wiring connection device. 7(b) and 8(b) are the same except for the thickness. Although the mounting hole H is one opening, it can be divided into three parts. Reference numeral H1 denotes a hole for the body portion, which has a shape corresponding to the shape (rectangular) of the body portion 11, but is slightly larger than the body portion 11 and is configured so that a wiring connection device can be inserted therethrough. Symbol H2 is a hole for the projection, and the horizontal length of H2 in FIGS. is slightly larger. Likewise, the length in the vertical direction is approximately the same as or slightly smaller than the heights of the first protrusion 13a and the second protrusion 13b. By making the width of H2 smaller than H1 and about the width of the projection 13, it is possible to reduce looseness when the wiring connection device is attached. A symbol H3 is a convex portion for the groove portion, and by fitting into the groove portion 11a, play can be reduced.

A wiring connection device according to an embodiment of the invention can be attached directly to the openings of FIGS. 7(b) and 8(b). No fixtures or partitions are required.

FIG. 7 shows a case where the top plate T is a thick member. Both the first protrusion 13a and the second protrusion 13b are in contact with the side surface of the mounting hole H (specifically, the inner surface of H2 in FIG. 7B). In FIG. 7A, both the tip portion 13a1 and the claw portion 13b2 are in contact with each other, and the wiring connection device is firmly fitted and held. The same applies when the top plate T is thicker. When the thickness is reduced, the claw portion 13b2 is no longer in contact with the tip portion 13a1, so the fitted state is maintained.

8, the top plate T is thin, and unlike FIG. 7, neither the first projection 13a nor the second projection 13b contacts the side surface (inner surface) of the mounting hole H. In FIG. Even in this case, as shown in the enlarged view of FIG. 8(c), the cutting edge (most distal end) of the distal end portion 13a1 hits the top plate T, and is sandwiched between the rear side of the collar portion 12 and the distal end portion 13a1, so that the wiring connection device can be securely connected. It fits in and is held.

According to the embodiment of the invention, the wiring connection device to be mounted by fitting into the mounting hole is provided with projections on two opposing side surfaces, respectively, and the projections are the first projection and the second projection provided in series in the insertion direction. Since it includes two protrusions, it can be attached to a wide range of top plates, etc., from thin to thick plates, and can be installed on the top plate of a table, etc., without the need for a frame, mounting member (adapter), or partition member. can be installed directly into the mounting holes provided.

If a mounting hole is provided in the top plate of a table or desk, the connector can be mounted upward on the top plate.

In the past, outlets and USB sockets were often casually placed on meeting desks, spoiling the aesthetic appearance. On the other hand, a hole (Fig. 7(b), Fig. 8(b)) having a shape suitable for the top plate is opened, and the wiring connection device according to the embodiment of the invention is simply fitted into the hole, as if it were built-in. It can provide a clean appearance like an outlet.

In the above description, the case of attaching to the top plate is taken as an example and the description is added. The top plate is an example, and can be attached to other members that can have attachment holes.

The present invention is not limited to the above embodiments, and various modifications are possible within the scope of the invention described in the claims, which are also included in the scope of the present invention. It goes without saying that
