Description

  The present invention relates to a separable power feeder for feeding power from a fixed part side to a movable part side approaching and separating from the fixed part side. The present invention also relates to a sash separable power feeder for feeding power to the heat generating means of a sash sliding door or sliding door using the separable power feeder.

By using a heat-generating glass with a heating element composed of a metal thin film that generates heat when energized, it prevents condensation of the glass and the generation of a cooling downdraft (cold draft) near the window. Or performing room heating. For example, see Patent Documents 1 to 5.
JP-A-10-101376 Japanese Patent Laid-Open No. 10-139492 JP-A-11-173028 JP 2000-191347 A JP 2002-32869 A

In order to generate heat in the heat generating glass, it is naturally necessary to supply power to the heating element. When the heat generating glass is fixed by fitting, the electrode of the heating element and the electrode of the energization control device connected to the power source can be easily connected by the conductive wire, and there is no problem. However, when the heat generating glass is used as a sliding door or sliding door (hereinafter referred to as a shoji), the shoji is opened and closed, so that the shoji is opened between the electrode of the heating element and the electrode of the energization control device. A separable power feeder (separable power feeder) is used that opens the circuit at times and closes the circuit when the sliding door is closed (see Patent Document 6).
JP 2002-309863 A

  This separable power feeder has a terminal electrically connected to the energization control device and attached to the vertical frame of the sash, and a terminal electrically connected to the electrode of the heat generating glass. The power receiving component is attached to the vertical shaft of the shoji, and when the shoji is closed, the power feeding component and the terminals of the power receiving component are in contact with each other so that energization is possible.

  However, the lower part of the shoji is slidably fitted to the lower rail of the sash lower frame via a door wheel, and the upper part is slidably fitted to the upper rail of the upper sash frame. Since a clearance is provided between the frame to ensure smooth sliding of the shoji, it can be swung within a range of several mm in the thickness direction of the shoji (inside and outside). Therefore, depending on how the force is applied to the shoji when closing the shoji or the wind pressure applied to the shoji, the position with respect to the vertical frame when the shoji reaches the closing position may change. Since an error may occur in the mounting position of the component, the terminal of the power receiving component does not always contact the terminal of the power supplying component correctly. Therefore, there is a problem that power is not supplied to the heating element even if the energization control device performs a power supply operation in the closed state of the shoji. Also, when the shoji is closed, the parts are likely to be damaged unless the terminals of the power receiving parts and the terminals of the power feeding parts can be contacted with a constant contact force.

The present invention has been made to solve the above problems. That is, the first problem of the present invention consists of a power supply component attached to the fixed side and a power reception component attached to the movable side, and can be energized when the terminal of the power supply component contacts the terminal of the power reception component. In the separable power feeder that is configured as described above, even if the position of the movable power receiving component approaches, or even if there is an error in the mounting position of both components, the terminal is not affected by this. It is to add a configuration in which comrades can reliably contact and supply power.
The second problem of the present invention consists of a power supply component attached to a sash frame and a power reception component attached to a shoji cage. When the shoji is closed, the terminal of the power supply component and the terminal of the power reception component can be energized. In the separable power feeder for supplying power to the heating element provided on the sash shoji heat-generating glass, even if the position when the shoji is closed fluctuates or there is an error in the mounting position This is to add a configuration in which the terminals can reliably contact each other and be supplied with power without being affected by the occurrence of the problem.

In order to solve the above first problem, the invention of claim 1 has a terminal electrically connected to the energization control device and is attached to the fixed portion and electrically connected to the load. The power receiving component has a terminal and is attached to the movable portion. When the movable portion is moved to the fixed portion side, the terminal of the power receiving component and the terminals of the power receiving component come into contact with each other and can be energized. In the separable power feeder, (a) one of the power supply component and the power reception component is provided with a horizontal axis perpendicular to the moving direction of the movable part, and one terminal of the power supply component and the power reception component is connected to the power supply component and the power reception component. A terminal holder provided to protrude in the other direction of the power supply component and the power reception component is rotatable around the horizontal axis within a predetermined angle range, and is parallel to the axis of the terminal and the axis of the horizontal axis.

The other terminal of the electric component and the power receiving component is provided. (C) Further, when the terminal of the power receiving component or the power receiving component provided with the terminal holder is not subjected to external force, the terminal holder receives the external force. The terminal axis is maintained at a fixed position that maintains a horizontal state at a predetermined position of the horizontal axis, and when the terminal receives an external force, an urging means is provided to allow displacement according to the external force. .
With the above configuration, when the power receiving component and the power receiving component are attached to the fixed portion and the movable portion that is in contact with and separated from each other with the axis of the terminal of the terminal holder facing the axis of the terminal receiving hole, the power receiving component becomes the power receiving component. If the axis of the terminal of the terminal holder and the axis of the terminal receiving hole coincide with each other when approaching, both terminals normally contact without any obstacles. Even when the position of the power receiving component approaches the power receiving component, or even if there is an error in the mounting position of both components, the tip of the terminal of the terminal holder contacts the periphery of the terminal receiving hole and receives external force. Since the terminal holder is rotatable within a predetermined angle range around the horizontal axis, and is movable within a predetermined distance range in a direction parallel to the horizontal axis, the terminal is at the bottom of the terminal receiving hole. Guided in the direction, the terminal of the terminal holder comes into reliable contact with the terminal at the bottom of the terminal receiving hole.

According to a second aspect of the present invention, in the separable power feeder according to the first aspect of the present invention, an attracting means that magnetically attracts the power supply component and the power reception component is provided.
When this attracting means is provided, the attracting means magnetically attracts the power supply component and the power receiving component when the movable portion approaches the fixed portion, so even if the attractive force between the movable portion and the fixed portion is weak, The contact state between the terminals is maintained.

With the above configuration, when the movable part comes close to the fixed part and both terminals come into contact with each other, the switch conducts and power feeding is started. Therefore, it is possible to prevent a spark from occurring when the terminals are in contact with each other.

In order to solve the second problem, the invention of claim 4 is characterized in that a power supply component having a terminal electrically connected to the energization control device and attached to the vertical frame of the sash and an electrode of the heat generating glass are electrically connected. Power receiving parts that are connected to the vertical shaft of the shoji with the terminals connected to each other, and when the shoji is closed, the power feeding parts and the terminals of the power receiving parts are in contact with each other and can be energized. In the sash separable power feeder, (a) one of the power supply component and the power reception component is provided with a horizontal axis perpendicular to the moving direction of the shoji , and one terminal of the power supply component and the power reception component is provided. A terminal holder provided so as to protrude in the other direction of the power supply component and the power reception component is rotatable around the horizontal axis within a predetermined angle range, and is parallel to the axis of the terminal and the horizontal axis. Within a predetermined distance range in each direction parallel to the axis (B) A funnel-shaped terminal receiving hole that opens in a direction opposite to the terminal of the terminal holder is provided on the other of the power receiving component and the power receiving component, and the bottom of the terminal receiving hole. (C) Further, the terminal of the power receiving component or power receiving component provided with the terminal holder is not subjected to external force by the terminal of the power receiving component or the power receiving component. When the terminal axis is maintained at a fixed position that maintains a horizontal state at a predetermined position on the horizontal axis, and when the terminal receives an external force, the terminal is provided with a biasing means that allows displacement according to the external force. It is a feature.
With the above configuration, when the power supply component and the power reception component are attached to the sash frame and the shoji cage with the axis of the terminal holder terminal facing the axis of the terminal receiving hole, respectively, If the axis of the hole matches, both terminals will contact normally without any obstruction. Even if the closing position of the shoji is displaced in the indoor or outdoor direction or there is an error in the mounting position of the parts, when the tip of the terminal of the terminal holder contacts the periphery of the terminal receiving hole and receives external force, the terminal holder The terminal is guided in the direction of the bottom of the terminal receiving hole because it can be rotated within a predetermined angle range and can be moved within a predetermined distance range in a direction parallel to the axis of the horizontal axis. The terminal of the terminal holder is in reliable contact with the terminal at the bottom of the terminal receiving hole.

According to a fifth aspect of the present invention, in the sash separable power feeder according to the fourth aspect of the present invention, there is provided an attracting means for magnetically attracting the power-feeding component and the power-receiving component. Yes.
When this adsorbing means is provided, the attracting means magnetically adsorbs the power supply component and the power receiving component when the shoji is closed. For example, the attractive force between the shoji cage and the sash frame of the shoji locking device is reduced. Even in this case, the contact state between the terminals is maintained.

According to a sixth aspect of the present invention, in the sash separable power feeder according to the fourth or fifth aspect of the present invention, one of the power supply component and the power reception component, the conductor connected to the terminal, the power supply component and the power reception component It is characterized in that a switch is provided that conducts when the terminals are in contact with each other and disconnects when the terminals are disconnected.
With the above configuration, when both terminals come into contact with each other when the shoji is closed, the switch conducts and power feeding is started. Accordingly, it is possible to prevent a spark from occurring when the terminals are in contact with each other.

  According to the first aspect of the present invention, even if the approaching position of the power receiving part to the power feeding part is displaced or there is an error in the mounting position of both parts, Since the tip of the terminal comes into contact with the periphery of the terminal receiving hole, the terminal holder swings or kneads, and the tip of the terminal of the terminal holder is guided toward the bottom of the terminal receiving hole. Contact the terminal at the bottom of the terminal receiving hole. Therefore, reliable power feeding is possible without being affected by the displacement of the approach position of the power receiving component or the error of the component mounting position.

Therefore, the reliability of power supply is improved.

  According to invention of Claim 3, after a movable part adjoins a fixed part and both terminals contact, a switch conduct | electrically_connects and electric power feeding is started. Therefore, it is possible to prevent a spark from occurring when the terminals are in contact with each other.

  According to the invention of claim 4, even if the closing position of the shoji varies in the indoor / outdoor direction or an error occurs in the mounting position of the parts, the tip of the terminal of the terminal holder is located around the terminal receiving hole when the shoji is closed. The terminal holder can be rotated within a predetermined angle range around the horizontal axis when receiving an external force in contact with the terminal, and also within a predetermined distance range in a direction parallel to the terminal axis and a direction parallel to the horizontal axis. Since the tip of the terminal is guided toward the bottom of the terminal receiving hole, the terminal of the terminal holder is in reliable contact with the terminal at the bottom of the terminal receiving hole. Therefore, it is possible to reliably supply power without being affected by the change in the closed position due to the installed state of the shoji screen or external force or the error in the component mounting position.

  According to the invention of claim 5, since the attracting means for magnetically attracting when the power supply component and the power receiving component are close to each other is provided, for example, the attractive force between the shoji cage and the sash frame of the shoji locking device Even when the voltage drops, the contact state between the terminals is maintained.

Since a switch that cuts off when the door is closed is provided, the switches are brought into conduction after the both terminals are in contact with each other when the shoji is closed, and power feeding is started. Therefore, it is possible to prevent a spark from occurring when the terminals are in contact with each other.

Next, embodiments of the present invention will be described with reference to the drawings.

3 is a front view of the power supply component, FIG. 4 is also a front center longitudinal sectional view, FIG. 5 is a left side view of the power reception component, FIG. 6 is a front view, FIG. 7 is a right view, and FIG. FIG. 9 is a cross-sectional view taken along the line XX of FIG.

  1 and 2 is a separable power feeder according to an embodiment of the present invention. The power supply component A is attached to a vertical frame 2 of a sash frame F corresponding to a fixed portion, and corresponds to a movable portion. It consists of the power receiving component B attached to the vertical fence 3 closely_contact | adhered to the vertical frame 2 at the time of closing of the shoji D to do. One end is connected to a distribution board 4 connected to a power supply (not shown), a conductor 5 wired in the wall is inserted into the vertical frame 2, and the other end of the conductor is described later for the power supply component A. It is connected to a terminal (reference numeral 14 in FIG. 4). In addition, one end of a conductive wire (reference numeral 9 in FIG. 2) inserted into the shoji downpipe is connected to a later-described terminal (reference numeral 25 in FIG. 5) of the power receiving component B, and the other end is connected to the heating glass 6 of the shoji. It is connected to the electrode of the heating element 7 that is carried. 2 in FIG. 2 is a controller provided in the middle of the conducting wire 5 so that it can be operated from the room. The exothermic glass 6 is known from the above-mentioned patent document as an example, and is a known one coated with a heating element such as a metal thin film that generates heat by resistance when the surface of the glass is energized.

  The power supply component A has a component main body 11 formed of an insulating synthetic resin. The component main body 11 is provided with holes 12 through which screws for fixing the component main body to the vertical frame 2 are provided at the top and bottom, and is wide on the front side and narrowed on the back side at a position spaced vertically between the upper and lower holes. A funnel-shaped terminal receiving hole 13 is formed. A terminal 14 is provided at the bottom of each terminal receiving hole 13. The end of the conducting wire 5 is connected to this terminal. A permanent magnet 15 is embedded between the upper and lower terminals 14 of the component main body 11, and the end of the magnetic plate 16 that is in close contact with both the magnetic poles protrudes between the upper and lower terminal receiving holes 13 to the front of the component main body 11. ing.

  The component body 11 is further provided with, for example, a proximity switch 17 having a make contact, and the other end of a conductor 18 having one end connected to the controller 8 is connected to both terminals of the proximity switch. The controller 8 sets one of the conditions for supplying power to the power supply component A through the conductor 5 that the proximity switch is closed.

  The power supply component A is fitted into an attachment hole (not shown) formed at a position slightly closer to the indoor side from a position where the vertical shovel 3 of the closed shoji abuts the vertical frame 2, and a terminal receiving hole 13. Is fixed with a screw screwed through the hole 12 in a state in which is oriented in a direction parallel to the opening / closing movement direction of the shoji D.

  On the other hand, the power receiving component B has a component main body 21 formed of the same resin material as that of the power supply component A. This component main body 21 also has a hole 22 through which screws for fixing the component main body to the vertical rod 3 of the shoji are provided at the upper and lower sides, and a receiving portion (housing) 23 opened on the front side is provided between the upper and lower holes. Have. And in the accommodating part, the terminal holder 24 is hold | maintained so that rotation is possible (namely, kneading motion is possible) and it returns to a fixed position so that it may mention later.

  The terminal holder 24 has terminals 25 projecting to the front side (vertical frame side) with an interval equal to the interval between the terminal receiving holes 13 of the power supply component A on the upper and lower sides. In addition, an actuator 26 corresponding to the proximity switch 17 of the power supply component A is provided on the front surface of the terminal holder 24. The form of the actuator 26 differs depending on the type of the proximity switch 17. The illustrated example is merely an example in which a projection is formed so as to press and close the make contact of the proximity switch 17. When the proximity switch 17 is a magnet switch, the actuator 26 is composed of a magnet and does not need to protrude.

  Various known techniques can be used as a specific structure for holding the terminal holder 24 so as to be rotatable and to return to a fixed position. An example of the structure is described below. A pin 27 that is inserted into the housing portion 23 and protrudes in the opposite direction to each terminal 25 is provided at the insertion portion, and a coil spring 28 having one end abutting against the back wall of the housing portion 23 is provided on each pin. The terminal holder 24 is biased in the front direction by being wound and locked. Further, a long long hole 29 is provided in the intermediate portion of the terminal holder 24 in the direction of urging by the coil spring 28, that is, in a direction parallel to the axis of the terminal 25, and a horizontal shaft fixed to the bottom of the component main body 21 in the long hole. 210 is loosely inserted. Accordingly, the terminal holder 24 can be rotated around the axis of the horizontal shaft 210 within a predetermined angle range, and at the same time, can be moved within a predetermined distance range in a direction parallel to the horizontal shaft 210 and a direction parallel to the axis of the terminal 25. It is. Another coil spring 211 is wound around the horizontal shaft 210, and the terminal holder 24 is urged toward the side surface of the housing portion by the coil spring. The horizontal shaft 210 serves to prevent the terminal holder 24 from being pulled out of the accommodating portion 23 by the urging force of the coil spring 28.

  Between the terminals 25 of the terminal holder 24, a magnetic plate 212 attracted by a magnet is attached toward the front side. The magnet 15, the magnetic plate 16, and the magnetic metal plate 212 of the power supply component A constitute a magnetic attraction means.

  With the above-described configuration, when the power receiving component B is fixed to the interior side of the interior side at the same height as the power feeding component A of the vertical rod 3 of the shoji D with the screw, the terminal 25 has its axis aligned with the power feeding component. It is attached so as to coincide on the common horizontal line with the axis of the terminal receiving hole 13 of A. When a force in an oblique direction is applied to the tip of the terminal 25 with respect to the horizontal line, the terminal holder 24 is tilted in the direction in which the force is applied, and when the force is removed, the coil spring 28 and / or the coil spring 211 is used. Returns to the state before force was applied.

  Conductive wires 9 are connected to the inner ends of the terminal holders 24 of the terminals 25 of the power receiving component B, and the conductive wires penetrate through the shovel 3 of the shoji through holes 213 formed on the back side of the component main body 21. The heat generating glass 6 is connected to the electrode of the heating element fitted in the vertical glass fitting groove 3a.

  When the above-mentioned power supply component A and power reception component B are attached at appropriate positions as shown in FIG. 1 and the door D is closed, the mounting positions of the power supply component A and the power reception component B are accurate. If the closing position of the shoji is normal, the tip of the terminal 25 of the power receiving component B contacts the terminal 14 of the power supply component A without contacting the periphery of the terminal receiving hole 13. In addition, when there is an error in the attachment position of the power supply component A and the power reception component B, or when the closing position of the shoji is shifted from the normal position within a range that is usually likely to occur about several mm, the tip of the terminal 25 of the power reception component B Contacts the periphery of the terminal receiving hole 13, and can be guided by this to contact the terminal 14 of the power supply component A. In either case, the proximity switch 17 is turned on by the actuator 26 when the terminal 14 of the power supply component A and the terminal 25 of the power reception component B approach each other. Accordingly, when the controller 8 is set to energize the heating element 7, the energization is started because the condition for turning on the proximity switch 17 is satisfied. Therefore, since electricity is applied after the terminals 14 and 25 are in contact, the occurrence of sparks when the terminals are in contact is prevented. Further, since the terminal holder 24 can slide in the contact direction of the terminal and is urged in the return direction by the coil spring, it can be contacted without applying an excessive force to the contact portion.

  Further, when the terminal 14 of the power supply component A and the terminal 25 of the power reception component B approach each other, the magnetic attracting means operates, so that the magnetic plate 212 of the terminal holder 24 is also magnetized by the power supply component A. Since it is adsorbed by being approached to the plate 16, even if wind pressure or other external force is applied to the shoji D and vibrates, the attracting force to the vertical frame of the shoji by the sash lock device is weak, so that the power supply component A Even if the power receiving component B is slightly separated, the terminal holder 24 is attracted to the power feeding component A by the magnetic attracting means, so that the electrical connection state of the terminals 14 and 25 is maintained.

  In the above, the case where the terminal holder is provided on the power receiving component B has been described. However, the terminal holder with the terminal facing the power receiving component B is provided on the power feeding component A side so as to be freely kneaded. Even if a receiving hole is formed and a terminal is provided at the bottom of the hole, the same effect as described above can be obtained.

  Above, a preferred embodiment used to supply power to a heat generating glass heating element provided on a sash shoji has been described, but the application of the present invention is not limited to this, the power supply component on the fixed side, It can be widely used when a power receiving component is attached to the movable side and power is supplied from the fixed side to the movable side.
