There is.

Jitsufuku No. 6-37729

In the structure of Patent Document 1, the weight of the connector, the downward load generated when fastening the screw for fixing the connector to the top plate, the downward load when the user connects the outlet plug, and the like are separated. It will be received by a beam-shaped overhang piece. It is considered that the strength of the overhanging piece is lowered by repeatedly receiving these loads, and it has been required to improve the robustness of fixing the connector to the top plate.

The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a connector having enhanced robustness for fixing to a top plate or a fixture with a connector provided with the connector.

In order to solve the above problems, the connector according to the first aspect of the present invention is a connector attached to the opening of the top plate, the upper member arranged on the upper side of the top plate, and the lower side of the top plate. The upper member includes a lower member arranged on the side, the upper member has an upper wall portion in which a through hole is formed, and a first holding portion, and the lower member is inserted into the through hole. It has a connecting portion and a second sandwiching portion that sandwiches the top plate together with the first sandwiching portion.

According to the above aspect, the user can easily connect an outlet plug or the like to the connection portion exposed through the through hole. Then, since the connector is fixed to the top plate by sandwiching the top plate between the first sandwiching portion and the second sandwiching portion, it is possible to enhance the robustness of fixing the connector to the top plate.

Here, the connector according to the above aspect may further include a bolt for fastening the upper member and the lower member.

In this case, the connector can be more firmly fixed to the top plate by sandwiching the top plate between the upper member and the lower member using the fastening force of the bolt. Further, even if a dimensional error occurs in the thickness of the top plate, the error can be absorbed by adjusting the tightening amount of the bolt, and the connector can be stably fixed to the top plate.

Further, the insertion port of the connection portion may be inclined to open on the front side and the upper side, and the bolt may extend toward the upper side toward the front side.

In this case, since the insertion port is inclined to the front side and the upper side to open, for example, when the user is standing or sitting on the front side of the top plate, the operation of inserting the outlet plug or the like into the insertion port is more difficult. It will be easy. Further, the bolt for fastening the upper member and the lower member also extends in an inclined manner to the front side and the upper side, so that, for example, when the upper member is formed by injection molding or the like, the fastening portion for fastening the bolt is formed. The extending direction and the die-cutting direction of the upper member can be matched.

Further, a recess that is recessed toward the upper side may be formed on the back surface of the top plate, and at least a part of the second sandwiching portion may be located in the recess.

In this case, the amount of protrusion of the lower member from the back surface of the top plate to the lower side can be reduced. Further, since the amount of protrusion of the lower member to the lower side can be reduced, for example, when a cover for covering the lower member is provided, the vertical dimension of the cover can be reduced.

Further, the fixture with a connector according to the second aspect of the present invention includes the connector of the above aspect, the top plate, and the legs supporting the top plate, and the back surface of the top plate has the second aspect. A contact surface with which the sandwiching portion abuts is provided, and the contact surface is inclined toward the lower side toward the front side.

According to the fixture with a connector of the above aspect, the direction of the fastening force generated by the bolt coincides with the normal direction of the contact surface receiving the fastening force. Therefore, the contact surface allows the bolt fastening force to be received more stably.

According to the above aspect of the present invention, it is possible to provide a connector having enhanced fixing to the top plate or a fixture with a connector provided with the connector.

Hereinafter, the connector of the present embodiment and the fixture with the connector will be described with reference to the drawings.
As shown in FIG. 1, a fixture with a connector (hereinafter referred to as a fixture 1) includes a top plate 2, a connector 3, a plurality of (two) legs 4, and a curtain plate 5. In the present embodiment, the fixture 1 includes two connectors 3, but the number of connectors 3 may be one or three or more. Further, the number of legs 4 can be changed as appropriate.

As shown in FIG. 2, the connector 3 of the present embodiment has two connecting portions 22. The number of connecting portions 22 included in the connector 3 may be one or three or more. In the example of FIG. 2, the connection portion 22 is an insertion port of an outlet plug for power supply, and has two insertion ports 22a. However, the type of the connection unit 22 can be changed as appropriate, and may be, for example, a USB (Universal Serial Bus) connector, a LAN (Local Area Network) connector, or the like. The number, shape, arrangement, etc. of the insertion ports 22a are appropriately changed according to the type of the connection portion 22. Further, one connector 3 may be provided with a plurality of types of connection portions 22.

(Direction definition)
In this embodiment, the XYZ Cartesian coordinate system is set and the positional relationship of each configuration is described. The direction along the X-axis is called the left-right direction, the direction along the Y-axis is called the front-back direction, and the direction along the Z-axis is called the up-down direction. The vertical direction is the normal direction of the floor surface on which the fixture 1 is installed. In the front-rear direction, the side where the connector 3 and the curtain plate 5 are provided is called the rear side, and the opposite side (the tip side of the arrow indicating the Y-axis) is called the front side.

Although detailed description will be omitted, the fixture 1 of the present embodiment is a so-called flap type, and the top plate 2 is rotatable. In the following description, as shown in FIG. 1, the positional relationship of each configuration in a state where the work surface 2a (upper surface) of the top plate 2 faces upward will be described. The fixture 1 does not have to be a flap type.

The two legs 4 are arranged at intervals in the left-right direction, and support the top plate 2 from below. A plurality of rolling members (casters) are provided at the lower ends of each leg portion 4. The curtain plate 5 is formed in a rectangular plate shape when viewed from the front-rear direction.

As shown in FIGS. 2 and 3, the insertion port 22a of the connecting portion 22 is opened so as to face the upper side and the front side (upward oblique front side). This makes it easier for the user to insert the outlet plug or the like into the insertion port 22a from the front side.

The top plate 2 is formed in a rectangular plate shape that is longer in the left-right direction than in the front-rear direction in a plan view. As shown in FIG. 1, two connectors 3 are arranged on the work surface 2a (upper surface) of the top plate 2 at intervals in the left-right direction. As shown in FIG. 4, two openings 2d are formed in the top plate 2. Each opening 2d has an oblong hole shape extending in the left-right direction. When the connector 3 is fixed to the top plate 2, the opening 2d is covered by the connector 3 and is not visible. The number and shape of the openings 2d can be appropriately changed according to the number and shape of the connectors 3.

As shown in FIGS. 5 and 6, a recess 2e that is recessed upward is formed in a portion of the back surface 2b of the top plate 2 that is adjacent to the opening 2d in the left-right direction. Two recesses 2e are arranged so as to sandwich the opening 2d with respect to one opening 2d. The bottom surface (inner surface facing downward) of each recess 2e is a contact surface 2c. That is, two contact surfaces 2c are arranged so as to sandwich the opening 2d with respect to one opening 2d. The contact surface 2c is a portion where the upper surface of the second sandwiching portion 23 of the connector 3 comes into contact with the contact surface 2c. As shown in FIG. 6, the contact surface 2c of the present embodiment is inclined so as to go downward toward the front side.

As shown in FIG. 4, the connector 3 has an upper member 10 arranged on the upper side of the top plate 2 and a lower member 20 arranged on the lower side of the top plate 2. Since the fixture 1 includes two connectors 3, the number of the upper member 10 and the number of the lower member 20 are also two, respectively. The two lower members 20 are connected by a cable C1. A cable C2 is connected to one of the lower members 20. The end of the cable C2 (not shown) is connected to a cable insertion port provided on the floor or wall surface. Power lines, optical fibers, and the like are housed inside the cables C1 and C2, depending on the type of connector 3.

The lower member 20 and the cables C1 and C2 are covered from the lower side by the cover 30. The cover 30 has a mounting portion 31, a side wall portion 32, and a lower wall portion 33, and extends in the left-right direction as a whole. A plurality of mounting holes 31a are formed in the mounting portion 31. The cover 30 is fixed to the top plate 2 by fastening a fixture such as a screw to the lower surface of the top plate 2 through the mounting hole 31a.

As shown in FIG. 5, the upper member 10 has an upper wall portion 11 and a first holding portion 12 (side wall portion). The upper wall portion 11 is formed in the shape of a thin plate. Two through holes 13 are formed in the upper wall portion 11. The two through holes 13 are arranged so as to be spaced apart from each other in the left-right direction. The first sandwiching portion 12 extends obliquely downward from the outer peripheral edge of the upper wall portion 11. The first sandwiching portion 12 is formed in the shape of a thin plate. The upper wall portion 11 and the first holding portion 12 cover the portion of the main body portion 21 of the lower member 20 that protrudes upward from the top plate 2. That is, the upper member 10 serves as a cover (blind) that covers the main body 21.

As shown in FIG. 5, two fastening portions 14 are formed inside the upper member 10 (a space surrounded by the upper wall portion 11 and the first holding portion 12). Each fastening portion 14 is formed in a substantially cylindrical shape, and a female screw portion is formed on the inner peripheral surface. The female screw portion may be formed in advance, or the female screw portion may be formed by being scraped by the male screw portion of the bolt B when the bolt B is screwed to the fastening portion 14. As shown in FIG. 7, the bolt B and the fastening portion 14 extend upward toward the front side.

As shown in FIG. 5, the lower member 20 has a main body portion 21, two connecting portions 22, and two second sandwiching portions 23. The two connecting portions 22 are arranged on the upper surface of the main body portion 21 at intervals in the left-right direction. Each connecting portion 22 is formed in a columnar shape. When the lower member 20 and the upper member 10 are combined, the main body 21 and the connecting portion 22 project upward from the work surface 2a through the opening 2d of the top plate 2. Further, each connecting portion 22 is inserted into the through hole 13 of the upper member 10. As a result, the connection portion 22 and the insertion port 22a are exposed through the through hole 13.

The two second holding portions 23 project from the lower end portion of the main body portion 21 in the left-right direction. An insertion hole 23a is formed in each of the second sandwiching portions 23. As shown in FIG. 6, the upper surface of the second holding portion 23 is inclined toward the lower side toward the front side. As shown in FIG. 7, the bolt B is inserted into the insertion hole 23a from below. The upper end member 10 and the lower member 20 are fixed by screwing the tip end portion of the bolt B to the fastening portion 14.

Here, due to the fastening force when the bolt B is screwed to the fastening portion 14, a downward force acts on the upper member 10 and an upward force acts on the lower member 20. The first sandwiching portion 12 is pressed against the working surface 2a of the top plate 2 by the force acting on the upper member 10. Further, the force acting on the lower member 20 presses the second holding portion 23 against the contact surface 2c of the top plate 2. In this way, the first sandwiching portion 12 and the second sandwiching portion 23 sandwich the top plate 2, so that the connector 3 is fixed to the top plate 2.

The upper member 10 may be formed of resin or the like, and the first holding portion 12 may be elastically deformed by pressing the first holding portion 12 against the working surface 2a by the fastening force of the bolt B. In this case, the gap between the first holding portion 12 and the top plate 2 is sealed, and even when a liquid or the like adheres to the work surface 2a of the top plate 2, the liquid or the like enters the inside of the connector 3. Can be suppressed.

As described above, the connector 3 of the present embodiment is a connector attached to the opening 2d of the top plate 2, and is arranged on the upper side member 10 arranged on the upper side of the top plate 2 and on the lower side of the top plate. The lower member 20 is provided. The upper member 10 has an upper wall portion 11 in which the through hole 13 is formed, and a first holding portion 12. The lower member 20 has a connecting portion 22 inserted into the through hole 13 and a second sandwiching portion 23 that sandwiches the top plate 2 together with the first sandwiching portion 12. According to this configuration, the user can easily connect an outlet plug or the like to the connection portion 22 exposed through the through hole 13. Then, by sandwiching the top plate 2 between the first sandwiching portion 12 and the second sandwiching portion 23, the connector 3 can be firmly fixed to the top plate 2. Thereby, for example, it is possible to prevent the connector 3 from being loosened from the top plate 2 due to the force when the outlet plug or the like is inserted into the insertion port 22a of the connection portion 22.

Further, the connector 3 further includes a bolt B for fastening the upper member 10 and the lower member 20. Therefore, the connector 3 can be more firmly fixed to the top plate 2 by sandwiching the top plate 2 between the upper member 10 and the lower member 20 by using the fastening force of the bolt B. Further, even if a dimensional error occurs in the thickness of the top plate 2, the error can be absorbed by adjusting the tightening amount of the bolt B, and the connector 3 can be stably fixed to the top plate 2.

Further, the insertion port 22a included in the connecting portion 22 is opened so as to be inclined forward and upward. As a result, for example, when the user is standing or seated on the front side of the top plate 2, the operation of inserting the outlet plug or the like into the insertion port 22a becomes easier. Further, the bolt B for fastening the upper member 10 and the lower member 20 also extends inclined to the front side and the upper side. Thereby, for example, when the upper member 10 is formed by injection molding or the like, the direction in which the fastening portion 14 extends can be made to coincide with the die-cutting direction of the upper member 10.

Further, the back surface 2b of the top plate 2 is provided with a contact surface 2c with which the second sandwiching portion 23 abuts, and the contact surface 2c is inclined so as to go downward toward the front side. With this configuration, the direction of the fastening force generated by the bolt B and the normal direction of the contact surface 2c that receives the fastening force coincide with each other. Therefore, the contact surface 2c makes it possible to receive the fastening force of the bolt B more stably.

Further, a recess 2e recessed upward is formed on the back surface 2b of the top plate 2, and at least a part of the second sandwiching portion 23 is located in the recess 2e (see FIG. 6). As a result, the amount of protrusion of the lower member 20 downward from the back surface 2b of the top plate 2 can be reduced. Further, since the amount of protrusion of the lower member 20 to the lower side can be reduced, the vertical dimension of the cover 30 can also be reduced.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, in the above-described embodiment, the insertion port 22a of the connecting portion 22 faces diagonally forward, but the insertion port 22a may simply face upward. In this case, the bolt B for fastening the upper member 10 and the lower member 20 may extend in the vertical direction, and the contact surface 2c may face downward without being inclined. Similarly, the fastening portion 14 may simply extend along the vertical direction.

In addition, it is possible to replace the constituent elements in the above-described embodiment with well-known constituent elements as appropriate without departing from the spirit of the present invention, and the above-described embodiments and modifications may be appropriately combined.
