Description

Door and window equipment

[0001] The present disclosure relates to a joinery device.

[0002] Devices incorporating solar cells into fixtures such as doors have been known for some time. For example, Patent Document 1 below discloses a door structure in which a door configured as a double sliding door is provided with a door frame into which a solar panel is embedded. In this door structure, the output wiring of the solar cells of the solar panel provided on the door is connected to a battery provided within a transom located above the door.

[0003] Japanese Patent Application Laid-Open No. 2003-293664

[0004] However, with the door structure described in Patent Document 1, there is a concern that when the door is slid open, the output wiring and its connection parts connecting the solar cell to the battery inside the door may become exposed and easily touched.

[0005] The present disclosure has been made in consideration of the above-mentioned circumstances, and aims to provide a fitting device that can suppress contact with a power receiving unit that receives power from a solar cell module.

[0006] In order to achieve the above-mentioned object, the building fixture device of the present disclosure comprises a building fixture frame, and a building fixture that is arranged to slide freely within the building fixture frame and has a panel section that includes a solar cell module within the frame section, and is characterized in that one of the upper and lower frames of the building fixture frame has a power receiving section that receives power from the power transmitting section of the building fixture in a position that always overlaps with the building fixture that slides between a closed position and a fully open position in a plan view.

[0007] The fitting device according to the present disclosure is configured as described above, and thus can prevent contact with the power receiving section that receives power from the solar cell module.

[0008] 1 is a schematic front view showing an example of a fitting device according to an embodiment of the present disclosure; FIG. 2 is a schematic partially cutaway cross-sectional view corresponding to the view of the X-X arrows in FIG. 1; FIG. 3 is a schematic partially cutaway longitudinal-sectional view corresponding to the view of the Y-Y arrows in FIG. 1; (a) is a schematic partially cutaway perspective view of the fitting device, and (b) is a schematic partially cutaway longitudinal-sectional view schematically showing a modified example of the fitting device. (a) and (b) are schematic partially cutaway longitudinal-sectional views respectively showing the modified examples of the fitting device.

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In some drawings, some of the detailed reference numerals used in other drawings are omitted. In the following embodiments, directions such as the up and down directions will be described based on the state in which an example of a fitting device according to this embodiment is installed.

[0010] 1 to 5 are schematic diagrams illustrating an example of a fitting device according to the present embodiment and a modified example thereof. As shown in FIGS. 1 to 3, the fitting device 1 according to the present embodiment includes a fitting frame 10 and a fitting 20 slidably arranged within the fitting frame 10 and having a panel 21 including a solar cell module 24 within a frame portion 30. This configuration allows power to be generated by the solar cell module 24 of the fitting 20. As shown in FIG. 2, one of the upper frame 14 and lower frame 12 of the fitting frame 10 is provided with a power receiving unit 16 that receives power from the power transmitting unit 38 of the fitting 20 in a position that always overlaps the fitting 20, which slides between a closed position and a fully open position, in a plan view. This configuration ensures that the power receiving unit 16 on the fitting frame 10 is always in a position where the fitting 20, which slides in the opening and closing directions, is always present, thereby preventing unintended contact with the power receiving unit 16.

[0011] In this embodiment, the power transmission unit 38 is provided on the upper frame 36 of the fitting 20, and the power receiving unit 16 is provided on the upper frame 14. This configuration is less susceptible to the effects of rainwater and the like compared to a configuration in which the power transmission unit is provided on the lower frame 33 of the fitting 20 and the power receiving unit is provided on the lower frame 12. Specifically, the fitting device 1 may be installed in an opening that penetrates a wall that separates the interior and exterior of a building. The fitting device 1 may be installed by fixing the fitting frame 10 to an appropriate frame substrate, such as a lintel, window sill, or pillar, that separates the four perimeters of the opening. The fitting device 1 may be used in window devices such as waist-high windows that are sized from about waist height of an adult to a suitable height above the ceiling, or bay windows that are sized from floor to a suitable height above the ceiling, or may even be used in door devices.

[0012] In this embodiment, the door and window device 1 includes two doors and windows 20, 20 arranged in a sliding manner within the door and window frame 10. These doors and windows 20, 20 are slidable along the longitudinal direction of rails 15, 13 provided on the upper and lower frames 14 and 12 of the door and window frame 10, respectively. The doors and windows 20 include an exterior door and an interior door and window frame 20A, respectively, arranged on the exterior (outdoor) side and an interior door and window frame 20B, respectively, within the door and window frame 10. The exterior door and window frame 20A and the interior door and window frame 20B are configured in substantially the same manner. Hereinafter, when there is no need to distinguish between the exterior door and window frame 20A and the interior door and window frame 20B, one of the doors and window frame 20A and the interior door and window frame 20B will be referred to collectively, omitting the terms "outdoor" and "indoor."

[0013] As shown in FIG. 1 , the door frame 10 is formed into a rectangular frame shape by left and right vertical frames 11, 11 that are elongated in the vertical direction, and an upper frame 14 and a lower frame 12 that are elongated in the horizontal direction. These left and right vertical frames 11, 11, upper frame 14, and lower frame 12 may be made of metal, or may be made of resin from the viewpoint of thermal insulation, or may be made of so-called fiber-reinforced resin containing reinforcing fibers such as glass fiber or carbon fiber. Furthermore, these left and right vertical frames 11, 11, upper frame 14, and lower frame 12 may each be an extrusion molded product having a substantially uniform cross-sectional shape along their entire length. Furthermore, these left and right vertical frames 11, 11, upper frame 14, and lower frame 12 may be joined to each other by suitable fasteners such as screws, welding, or the like. In the illustrated example, the longitudinal ends of the left and right vertical frames 11, 11 are joined to the longitudinal ends of the upper frame 14 and lower frame 12 in a so-called jointed manner, but they may also be joined in a vertical or horizontal manner. The interior ends of the inner periphery of the left and right vertical frames 11, 11, upper frame 14, and lower frame 12 are provided with cover pieces that extend to cover the door-end, upper end, and lower end of the fixture 20. The outer periphery of the left and right vertical frames 11, 11, upper frame 14, and lower frame 12 may be provided with appropriate gaskets that elastically deform and fit tightly to the frame base.

[0014] The rail portion 13 of the lower frame 12 protrudes from the projected surface (the surface facing upward) of the lower frame 12 toward the upper frame 14 and extends substantially the entire length of the lower frame 12. As shown in FIG. 3 , the lower frame 12 is provided with the rail portion 13, which includes an exterior rail portion 13A that guides the lower end of the exterior fitting 20A and an interior rail portion 13B that guides the lower end of the interior fitting 20B. The exterior rail portion 13A and the interior rail portion 13B are arranged parallel to each other with a gap in the projected direction (the direction along the thickness of the fitting) of the lower frame 12. The projected dimension between the exterior rail portion 13A and the interior rail portion 13B may be appropriately determined depending on the thickness of the exterior fitting 20A and the interior fitting 20B so that they are arranged close to each other. These outdoor rail portion 13A and indoor rail portion 13B are approximately plate-shaped and arranged so that the thickness direction is the prospective direction, and on each upper end surface, an engaging protrusion that protrudes upward and extends over approximately the entire length to engage with the door roller 35 of the building fixture 20 described below.

[0015] The rail portion 15 of the upper frame 14 protrudes toward the lower frame 12 from the lower surface 14a, which is the projected surface (the surface facing downward) of the upper frame 14, and extends over substantially the entire length of the upper frame 14. The upper frame 14 is provided with the rail portion 15, which includes an exterior rail portion 15A that guides the upper end of the exterior fitting 20A and an interior rail portion 15B that guides the upper end of the interior fitting 20B. The exterior rail portion 15A and the interior rail portion 15B are arranged parallel to each other and spaced apart in the projected direction of the upper frame 14. The exterior rail portion 15A of the upper frame 14 is located directly above the exterior rail portion 13A of the lower frame 12, and the interior rail portion 15B of the upper frame 14 is located directly above the interior rail portion 13B of the lower frame 12. The exterior rail portion 15A and the interior rail portion 15B are generally plate-shaped and arranged with their thickness direction aligned with the projection direction. An example of the specific configuration of the power receiving unit 16 provided on the upper frame 14 will be described later. The left and right vertical frames 11, 11 may also be provided with protruding pieces extending along substantially their entire length, protruding in directions facing each other so as to be aligned with the rail portions 15, 13 of the upper frame 14 and the lower frame 12 in the projection direction. Note that the building frame 10 is not limited to the configuration shown in the illustration, and various other configurations may be used.

[0016] As shown in FIGS. 1 to 3 , the fitting 20 comprises a rectangular panel portion 21 and a frame portion 30 surrounding the four periphery of the panel portion 21. As shown in FIG. 3 , the panel portion 21 has a multi-layered structure with multiple (two in the illustrated example) light-transmitting plates 22, 22 extending along the thickness of the fitting. These light-transmitting plates 22, 22 may be glass plates or may be made of a synthetic resin material such as acrylic or polycarbonate. The light-transmitting plates 22, 22 are spaced apart in the thickness direction by appropriate spacers 23 formed in a roughly frame shape along the four periphery. Additionally, an appropriate sealant may be provided around the outer periphery of the spacer 23 to seal the vacuum layer or hollow space filled with various gases between the light-transmitting plates 22, 22.

[0017] The solar cell module 24 is disposed along one thickness-wise surface of one of the light-transmitting plates 22, 22 of the panel unit 21. In the illustrated example, the solar cell module 24 is disposed along the exterior-facing surface of the exterior-side light-transmitting plate 22, but this is not limiting. The solar cell module 24 may include a single or multiple thin-film solar cells including a photoelectric conversion layer formed by coating or the like on the light-transmitting plate 22 or an appropriate substrate. Examples of such thin-film solar cells include perovskite-type solar cells that use a perovskite compound as a light-absorbing material, as well as silicon-type solar cells. The solar cell module 24 is translucent and may be disposed over substantially the entire thickness-wise surface of the light-transmitting plate 22 of the panel unit 21. The solar cell module 24 is provided with positive and negative electrodes, which are electrically connected to appropriate electric wires 25, 25.

[0018] As shown in Figure 1, the stile 30 is a rectangular frame made up of a leading stile 31 and a joining stile 32, which constitute left and right vertical stiles elongated in the vertical direction, and an upper stile 36 and a lower stile 33, which are elongated in the horizontal direction. The leading stile 31, joining stile 32, upper stile 36, and lower stile 33 may be made of metal, but as mentioned above, they may also be made of resin from the perspective of thermal insulation, or may be made of fiber-reinforced resin. The leading stile 31, joining stile 32, upper stile 36, and lower stile 33 may also be extrusion molded products with a substantially uniform cross-sectional shape along their entire length. The door end frame 31, the joint frame 32, the upper frame 36, and the lower frame 33 may be joined to each other by suitable fasteners such as screws, welding, etc. In the illustrated example, the longitudinal ends of the left and right door end frames 31 and the joint frame 32 are joined to the longitudinal ends of the upper frame 36 and the lower frame 33 in a so-called jointed manner, but they may also be joined in a vertical or horizontal manner.

[0019] As shown in Figure 3, panel receiving grooves 30a that receive the four peripheral edges of the panel section 21 are provided on the inner periphery of each of these end stile sections 31, joint stile section 32, upper stile section 36, and lower stile section 33. The indoor side, which is on one side of the groove width direction of the panel receiving groove 30a, is defined by extension pieces that extend from the indoor side edges of the inner periphery of each of the end stile section 31, joint stile section 32, upper stile section 36, and lower stile section 33 so as to cover the edge of the panel section 21. The outdoor side, which is on the other side of the groove width direction of the panel receiving groove 30a, is defined by ridge members 30b attached to the outdoor side edges of each of the end stile section 31, joint stile section 32, upper stile section 36, and lower stile section 33. In the illustrated example, a receiving base 26 is interposed between the bottom of the panel receiving groove 30a and the outer peripheral end face of the panel portion 21, but this is not a limitation. Also, an appropriate gasket that fits tightly against the panel portion 21 may be provided inside the panel receiving groove 30a so as to extend around substantially the entire circumference. The panel receiving groove 30a that receives the four peripheral ends of the panel portion 21 is not limited to a configuration in which the other side in the groove width direction is defined by a pressing edge member 30b as in the illustrated example, and various other configurations may be used.

[0020] The lower frame portion 33 has a receiving groove 34 that receives the rail portion 13 of the lower frame 12. The receiving groove 34 is open downward and extends approximately the entire length of the lower frame portion 33. A door roller 35 is provided in the lower frame portion 33 so as to be exposed at the bottom of the receiving groove 34. The door roller 35 is held by an appropriate bearing portion so as to be rotatable around an axis along the thickness direction of the fitting. The door roller 35 rolls along the rail portion 13 of the lower frame 12, guiding the lower end side of the fitting 20 in the left-right direction. The outer peripheral surface of the door roller 35 has an engagement groove that opens radially outward, extends around the entire circumference, and engages with an engagement protrusion of the rail portion 13 of the lower frame 12. The door rollers 35 may be provided at multiple locations (e.g., two locations) along the length of the lower frame portion 33. Seal portions 33a, 33a are provided on both edges of the receiving groove 34 in the opening width direction, extending in directions facing each other and with their leading ends in the extending direction approaching or abutting the rail portion 13. These seal portions 33a, 33a are provided so as to extend over substantially the entire length of the receiving groove 34. These seal portions 33a, 33a may be formed from, for example, a soft resin such as soft PVC (polyvinyl chloride), a thermoplastic elastomer (TPE), rubber, or the like.

[0021] The door end stile 31 and the door joint stile 32 may also be provided with receiving grooves that receive the protruding pieces provided on the left and right vertical frames 11, 11. Similar seals may also be provided on both edges of the receiving grooves in the opening width direction of the door end stile 31 and the door joint stile 32. An appropriate handle may also be provided in an appropriate location on the door end stile 31. The door joint stile 32 of the exterior fitting 20A and the door joint stile 32 of the interior fitting 20B, which are arranged so as to overlap in the fitting thickness direction in the closed position, may be provided with appropriate seals that abut or are close to each other, or with appropriate locking devices such as crescent locks.

[0022] The upper frame portion 36 is provided with a receiving groove 37 that receives the rail portion 15 of the upper frame 14. This receiving groove 37 is provided so as to open upward and extend over substantially the entire length of the upper frame portion 36. The groove depth of this receiving groove 37 may be an appropriate dimension so that, when the fitting 20 is installed in a so-called kendon shape, the rail portion 13 of the lower frame 12 can be received in the receiving groove 34 of the lower frame portion 33 while the rail portion 15 of the upper frame 14 is received therein. Similar to the receiving groove 34 of the lower frame portion 33, seal portions 36a, 36a are provided on both edges of the opening width direction of this receiving groove 37 that extend in directions facing each other and whose extending tips are close to or abut the rail portion 15.

[0023] A power transmission unit 38 is provided on at least one of the upper surfaces 36b, 36b on both sides of the receiving groove 37 in the opening width direction of the upper frame portion 36, and a power receiving unit 16 is provided facing the power transmission unit 38. This configuration reduces electrical conductivity problems caused by dust accumulation, compared to, for example, a configuration in which a power transmission unit is provided on the bottom side of the receiving groove 37 and a power receiving unit is provided on the underside of the rail portion 15 opposite it. The power transmission unit 38 is an elongated current-carrying unit 39 that is elongated in the opening and closing direction of the fitting 20 (the longitudinal direction of the rail portion 15), and the power receiving unit 16 is a terminal portion 17 that receives power through contact with the elongated current-carrying unit 39. With this configuration, electrical conductivity is achieved by attaching the fitting 20 so that the elongated current-carrying unit 39 contacts the terminal portion 17 on the fitting frame 10. This facilitates electrical connection between the fitting 20 and the fitting frame 10, compared to a configuration requiring the connection of output wiring, etc. In addition, electricity can be supplied when the door frame 20 is opened or closed, or even in the open position, and compared to a configuration in which electricity can be supplied only in a specified position such as the closed position, the electricity generated by the solar cell module 24 can be efficiently received on the door frame 10 side.

[0024] The terminal portion 17 is biased toward the elongated current-carrying portion 39. With this configuration, as described above, electricity can be stably passed when the fitting 20 is slid along the rail portion 15 or even if there is a fitting error. One of the width dimension of the elongated current-carrying portion 39 and the dimension of the corresponding terminal portion 17 is larger than the other. With this configuration, as described above, electricity can be stably passed when the fitting 20 is slid along the rail portion 15 or even if there is a fitting error.

[0025] Specifically, elongated conductive portions 39, 39 constituting a pair of power transmission portions 38, 38 are provided on each of the upper side surfaces 36b, 36b of the upper frame portion 36. The upper side surfaces 36b, 36b of the upper frame portion 36 form the upper end surfaces of the wall portions that define both sides of the receiving groove 37 in the groove width direction, and are formed to be located at approximately the same height and to be approximately coplanar. One of these elongated conductive portions 39, 39 may be electrically connected to the positive electrode of the solar cell module 24 via an appropriate electric wire 25, etc., and the other may be electrically connected to the negative electrode of the solar cell module 24 via an appropriate electric wire 25, etc. As shown in FIG. 2 , these elongated conductive portions 39, 39 have the same width. These elongated conductive portions 39, 39 may be provided to extend substantially the entire length of the groove longitudinal direction. These elongated conductive portions 39, 39 may be formed from an appropriate electrically conductive metal, etc.

[0026] As shown in Figure 2, the power receiving unit 16 (terminal unit 17) is located in a position that overlaps the door frame stile 32 of the fitting 20 in the closed position in a plan view. With this configuration, it is possible to effectively increase the effective opening width in the fully open position, while, as described above, the power receiving unit 16 (terminal unit 17) on the fitting frame 10 side is always in a position where the fitting 20 that slides in the opening and closing direction is present, thereby preventing unintentional contact with the power receiving unit 16 (terminal unit 17). This power receiving unit 16 (terminal unit 17) may be located in a position that overlaps the door edge stile 31 of the fitting 20 in the fully open position in a plan view, as shown by the two-dot chain line in Figure 2.

[0027] Specifically, terminal portions 17, 17 constituting a pair of power receiving portions 16, 16 are provided on both sides of the rail portion 15 on the underside 14a of the upper frame 14 in the prospective direction. One of these terminal portions 17, 17 may be conducted to the positive electrode of the solar cell module 24 via a long current-carrying portion 39 and an appropriate electric wire 25, etc., and the other may be conducted to the negative electrode of the solar cell module 24 via a long current-carrying portion 39 and an appropriate electric wire 25, etc. Furthermore, the door frame 10 may be provided with a power storage unit or the like that stores the power received at these terminal portions 17, 17, and may further be provided with a drive unit that uses that power to open and close the door 20. Instead of or in addition to providing such a power storage unit or drive unit on the door frame 10 side, a configuration may be adopted in which they are provided on the door 20 side. Furthermore, the fitting device 1 may be configured as a solar power generation system by electrically connecting these terminal portions 17, 17 to an appropriate power storage device or the like provided outside the fitting device 1 by appropriate electric wires or the like.

[0028] These terminals 17, 17 are positioned so that they are aligned with each other in the longitudinal direction of the rail portion 15. The dimension of these terminals 17, 17 along the rail longitudinal direction may be smaller than the dimension along the front (left-right) direction of the joint stile portion 32. As shown in FIG. 3 , these terminals 17, 17 are positioned so that their lower ends are positioned at the same height, and their widths along the front (left-right) direction are the same. In the illustrated example, the width of these terminals 17, 17 is smaller than the width of the elongated conductive portions 39, 39, but they may be larger. The width of these terminals 17, 17 and the elongated conductive portions 39, 39 may be approximately 1.1 to 2 times, or 1.2 to 1.6 times, that of the other. Alternatively, the width of these terminals 17, 17 and the width of the elongated conductive portions 39, 39 may be approximately the same. These terminal portions 17, 17 have the same configuration, so one of them will be described below as an example.

[0029] As shown in Figures 2 and 4(a), the terminal 17 includes a fixed piece 17a fixed along the lower surface 14a of the upper frame 14 and a spring-like piece 17b extending from the fixed piece 17a and projecting downward from the lower surface 14a. Note that Figure 2 illustrates a state in which the upper frame 14 is cut at a position where the terminal 17 will not be broken. Also, an example is shown in which an appropriate spacer is provided between the lower surface 14a of the upper frame 14, which is formed into an inclined plane, and the terminal 17 so that the lower ends of the terminals 17 are at the same height, but this is not a limitation. The terminal 17 is configured with a fixed piece 17a provided on both sides of the spring-like piece 17b in the longitudinal direction of the rail. Compared to a configuration in which the fixed pieces 17a are provided with cantilevered spring pieces 17b, this configuration allows for stable contact with the elongated conductive parts 39 when they rub against each other as the fitting 20 is opened or closed, and also prevents peeling. The spring pieces 17b are formed in a pantograph (diamond) shape, and include pieces that slope apart from the opposing ends of the fixed pieces 17a downward, and inclined pieces that slope closer together from the ends of the separated inclined pieces downward, with their tips connected to each other. The tips of the spring pieces 17b come into contact with the elongated conductive parts 39 as the spring pieces 17b elastically deform.

[0030] The terminal 17 described above may be formed from an appropriate metal or the like having good conductivity. The spring-like piece 17b of the terminal 17 is not limited to the above-described configuration and may be configured to be elastically deformable generally in the vertical direction and to contact the elongated current-carrying portion 39 with elastic deformation, or may have various other configurations. Furthermore, the terminal 17 biased toward the elongated current-carrying portion 39 is not limited to a configuration in which the contact portion with the elongated current-carrying portion 39 itself is the spring-like piece 17b. It may also be configured such that the contact portion with the elongated current-carrying portion 39 is biased by an appropriate spring or the like separate from the contact portion and is thereby expandable generally in the vertical direction. For example, the terminal 17 may include a pin-shaped electrode or an umbrella-shaped electrode biased in the vertical direction by a spring or the like.

[0031] In the above example, the terminals 17, 17 are provided in a position that overlaps the joint frame 32 of the fitting 20 in the closed position in a plan view, but this is not limited to this example and the terminals may be provided in other positions. The terminals 17, 17 may be provided in a position that always overlaps the fitting 20 that slides between the closed position and the fully open position in a plan view, and depending on the movable range of the fitting 20, they may be provided so as to be located closer to the door edge than the joint frame 32 of the fitting 20 in the closed position.

[0032] Next, modified examples of the fitting device will be described with reference to Figures 4(b) and 5(a) and (b). In each of the following modified examples, differences from the previously described example will be mainly described, and explanations of similar configurations will be omitted or briefly explained. In addition, in each of the following modified examples, explanations of the effects achieved similarly to the previously described example will be omitted or briefly explained.

[0033] 4(b) is a schematic diagram of a fitting device 1A according to a first modification. In this modification, the elongated conductive portions 39, 39 constituting a pair of power transmission portions 38, 38 are provided at intervals in the thickness direction of the fitting on the upper surface 36b on one side of the groove width direction of the receiving groove 37 of the upper frame portion 36A. In other words, in this modification, no power transmission portion is provided on the upper surface 36b on the other side of the groove width direction of the receiving groove 37 of the upper frame portion 36A. The terminal portions 17, 17 constituting a pair of power receiving portions 16, 16 are provided at intervals in the projection direction on one side of the rail portion 15 on the lower surface 14a of the upper frame 14A so as to be able to abut against the elongated conductive portions 39, 39.

[0034] FIG. 5( a) is a schematic diagram of a second modified example of a fitting device 1B. In this modification, similar to the example shown in FIG. 3, the elongated conductive portions 39, 39 constituting a pair of power transmitting portions 38, 38 are provided on the upper surfaces 36b, 36b on both sides of the receiving groove 37 of the upper frame portion 36 in the groove width direction. Each of the pair of power receiving portions 16A, 16A includes multiple terminal portions 17, 17, 17. This configuration allows for more stable power supply. The power receiving portion 16A on one side of the rail portion 15 on the underside 14a of the upper frame 14B in the projection direction includes two terminal portions 17, 17 spaced apart in the projection direction, and the power receiving portion 16A on the other side in the projection direction includes two terminal portions 17, 17 spaced apart in the projection direction.

[0035] Figure 5(b) shows a schematic diagram of a fitting device 1C according to a third modification. In this modification, a receiving groove is provided in each wall defining both sides of the receiving groove 37 of the upper frame portion 36B in the groove width direction, opening at the upper end surface and extending the entire length. The groove bottom surfaces 36Bb of these receiving grooves are provided with elongated conductive portions 39, 39 constituting a pair of power transmission units 38, 38. This configuration can prevent unintended contact with the elongated conductive portions 39, 39, compared to the configurations described above in which the elongated conductive portions 39 are provided on the upper surfaces 36b of the upper frame portions 36, 36A.

[0036] The terminals 17A, 17A constituting the pair of power receiving portions 16B, 16B of the upper frame 14C have an expandable pin structure. These terminals 17A, 17A include cylindrical holders 17Aa, 17Aa fixedly attached to the underside 14a of the upper frame 14C, and pin-shaped conductive portions 17Ab, 17Ab inserted into the cylindrical holders 17Aa so as to be freely retractable. The pin-shaped conductive portions 17Ab, 17Ab are biased downward by biasing members such as springs provided within the cylindrical holders 17Aa, 17Aa. The pin-shaped conductive portions 17Ab, 17Ab are positioned so as to be able to abut against the elongated conductive portions 39, 39 of the upper frame portion 36B, respectively.

[0037] In this modification, the elongated conductive portions 39 are provided on the groove bottom surfaces 36Bb of the housing grooves, but they may also be provided on the groove side surfaces of the housing grooves. In this case, the terminal portions 17A may be modified as appropriate. Furthermore, the different configurations described in the above examples may be modified, rearranged, or combined as needed.
