In this regard, as described in Patent Document 1, the locking protrusion of the substrate is fitted into the engaged hole of the terminal plate, the terminal plate is sandwiched between the pair of locking pieces of the substrate, and the step portion of the terminal plate Is inserted into the through hole of the substrate, accuracy is required for the relative positional relationship and dimensional relationship between the terminal plate, the locking piece, and the through hole.

  That is, when the terminal plate is attached with a predetermined accuracy because the pair of engaging pieces elastically sandwich the terminal plate and the stepped portion of the terminal plate is inserted into the through-hole to restrict the terminal plate from rising. High accuracy is required for the position of the pair of engaging pieces and the dimension of the terminal position in the width direction, and high accuracy is required for the dimension of the through hole and the dimension of the stepped portion. In addition, if this precision falls, not only the position precision of a terminal board will fall, but it is also considered that the lifting of a terminal board cannot be controlled.

  According to this configuration, the engaging portion at the other end of the terminal plate is engaged with the engaged portion inside the box body, and the extension piece is bent inside the box body by bending the extension piece at one end of the terminal plate. The terminal board can be supported on the box body by being crimped to the crimping portion. In particular, since the extension piece is bent and crimped to the part to be crimped, even if there is some error between the terminal board and the box body, the terminal board is supported by crimping without being affected by the error due to bending. Realize. Further, by disposing the diode in the displacement portion, the protrusion of the diode can be suppressed. Therefore, the terminal box for solar cell modules which can hold | maintain a terminal board reliably with respect to the position set with respect to the box main body was comprised small.

The electric power cable E has a coating 12 such as an insulating resin that can be flexibly deformed on the outer periphery of the conducting wire 11 such as a copper alloy. It has a formed structure. With such a structure, in this terminal box, power from a plurality of solar cell modules can be taken out via the positive power cable Ea and the negative power cable Eb.

  The terminal box of the present invention can be attached and used in an arbitrary posture. The direction will be described according to the vertical and horizontal directions corresponding to the posture shown in FIG. The direction perpendicular to the plane of the drawing is referred to as the thickness direction, and in particular, the near side in the thickness direction is referred to as the front side, and the opposite side is referred to as the back side.

[Box body]
As shown in FIGS. 1, 2, 4, and 5, the box body A has a size in which the cover plate B is fitted, and the box-like wall 1 arranged at a position surrounding the opening space As described above is in the thickness direction. It is integrally formed in the form of standing up. The box-like wall 1 is composed of a horizontal wall portion 1A arranged at the upper and lower positions and a vertical wall portion 1B arranged at the left and right positions, and a groove portion 2 is formed in an annular shape on the inner periphery thereof. A flange-shaped portion 3 is integrally formed on the outer periphery of the box-shaped wall 1, and a strip-shaped horizontal frame 4 is formed integrally in the opening space As. The vertical frame 5 is integrally formed.

  By forming the horizontal frame 4 in this way, the main opening S is formed above the horizontal frame 4. Further, by forming the three vertical frames 5, four fitting openings T (an example of a fitting portion) surrounded by the vertical frame 5, the horizontal frame 4, and the box-like wall 1 are formed. The main opening S and the fitting opening T penetrate the box body A in the thickness direction, and the fitting opening T functions as a fitting portion into which the displacement portion 24 (see FIG. 3) of the terminal board C is fitted.

  On the lower side of the fitting opening T (an example of the fitting part), a pair of left and right fitting protrusions 6 (an example of an engaged part) are integrally formed on the box body A in a rib shape protruding upward. Has been. The fitting projection 6 has a function of engaging with a slit 26 (see FIG. 3) as an engaging portion as will be described later, but the number of the fitting projections 6 is one or three. The shape of the engaged portion may be cylindrical or prismatic.

  In the horizontal frame 4, a restricting portion 4 </ b> R that rises on the surface side is integrally formed at a portion to which the vertical frame 5 is connected and both end positions of the horizontal frame 4. Further, an opening edge 4 </ b> S (an example of a pressure-bonded portion) that is inclined toward the lower side of the box main body A is formed on a part of the horizontal frame 4 facing the main opening S toward the back side of the box main body A. Has been.

  As the cable support portion Ac described above, first cable support portions Ac1 are formed at both left and right end positions outside the lateral wall portion 1A on the lower side of the box-shaped wall 1. In addition, a second cable support portion Ac2 that supports the power cable E is also formed in the lower portion outside the left and right vertical wall portions 1B of the box-shaped wall 1.

  The first cable support portion Ac1 and the second cable support portion Ac2 include a cable arrangement groove 15 that opens to the back side of the box body A, a clamper support recess portion 16, and a spacer support recess portion 17. The drawing shows a mode in which the power cable E is supported by the first cable support portion Ac1 and the second cable support portion Ac2 is not used, and a partition is formed on the outer end side of the second cable support portion Ac2. ing. By forming the partition wall, entry of water, dust or the like into the inside of the box body A is prevented. On the other hand, in the configuration in which the power cable E is supported by the second cable support portion Ac2 and the first cable support portion Ac1 is not used, a partition wall is formed in the first cable support portion Ac1 so that water and dust can enter. Is blocked. That is, this terminal box has a basic structure in which the first cable support portion Ac1 and the second cable support portion Ac2 can be selected and used, and a partition is formed in the unused one.

  When the power cable E is supported by either the first cable support portion Ac1 or the second cable support portion Ac2, the clamper 18 is pressure-bonded to the end portion of the power cable E, and the spacer 19 is externally fitted. When supporting, a plurality of projecting pieces 18 A projecting in the outer peripheral direction of the clamper 18 are engaged with the clamper support recess 16, and the spacer 19 is inserted into the spacer support recess 17. The spacer 19 is made of an insulating resin, and includes a hold portion 19a for embedding the power cable E, and a pair of fitting arm portions 19b that are frictionally fitted to the inner surface of the spacer support recess 17. .

  In particular, when the power cable E is supported by either the first cable support portion Ac1 or the second cable support portion Ac2, the lead wire 11 of the power cable E is connected to the folded portion 25 (see FIG. 3) of the terminal plate C at the end position. Reference level) of the power cable E at the first cable support portion Ac1 and the second cable support portion Ac2 so as to be in a position in contact with (or close to) the surface of the reference (the level in the thickness direction of the box body A). Are unified.

(Terminal board)
As shown in FIG. 3, the terminal plate C is formed by pressing a metal plate made of a conductor such as a copper alloy. That is, a tongue-shaped extension piece 21 is formed on one end side, and a conduction portion 22 is formed at a portion continuous with the extension piece 21. The intermediate wall portion 23 is formed by bending the portion continuous with the conductive portion 22 at a right angle, and the portion continuous with the intermediate wall portion 23 is further bent at a right angle so that the intermediate position has a stepped shape lower than the surface of the conductive portion 22. A displacement portion 24 to be a level is formed. In addition, the low level means the form which is displaced to the back surface side of the box main body A in the posture attached to the box main body A with reference to the surface on one end side where the extension piece 21 and the conductive portion 22 are formed. ing.

  A folded portion 25 which is folded back in a U-shape is formed at the other end position connected to the displacement portion 24, and an upper end portion 25a is formed by further folding the extended end of the folded portion 25 at a right angle to the direction of the displacement portion 24. ing. A pair of slits 26 (an example of an engaging portion) is formed by cutting out both ends in the width direction at the end portion (the other end position) of the folded portion 25.

  The number of slits 26 as the engaging portions may be one or three or more, and the shape of the engaging portions may be a simple circular hole or a square hole.

  The width of the displacement portion 24 of the terminal plate C is slightly shorter than the width of the fitting opening T described above, and the length of the displacement portion 24 in the longitudinal direction of the terminal plate C (from the intermediate wall portion 23 to the folded portion 25). The length to the end of the fitting opening T is slightly shorter than the vertical dimension of the fitting opening T. Thereby, it becomes possible to fit the displacement part 24 with respect to the fitting opening T without a gap. Further, in a state where the terminal plate C is fitted in the fitting opening T, the dimension of each part of the terminal plate C is measured in the thickness direction of the horizontal frame 4 so that the back surface side of the conductive portion 22 is in close contact with the front surface side of the horizontal frame 4 Is set.

  In this way, when the terminal plate C is fitted into the fitting opening T, the pair of left and right fitting projections 6 are fitted into the slits 26 of the terminal plate C, and the intermediate wall portion 23 is lateral. It contacts the lower surface of the frame 4. Next, the extension piece 21 of the terminal board C fitted into the fitting opening T is bent to the back side of the box body A, so that the extension piece 21 is formed on the opening edge 4S (an example of the part to be pressed) of the horizontal frame 4. The state of pressure contact is reached, and the movement of the conduction portion 22 in the surface direction is restricted. Further, since the terminal plate C is fitted in the fitting opening T, the movement of the terminal plate C in the vertical direction and the horizontal direction is also restricted.

  The width of the extension piece 21 is set to be slightly smaller than the width of the conduction portion 22, and a first groove portion G <b> 1 having a shape in which the conduction portion 22 is cut out along the width of the extension piece 21 is formed. A second groove G2 having a shape cut out in the width direction is formed in a portion adjacent to the wall portion 23.

  A through hole 22H is formed in the conduction portion 22, and a bent piece 22a is formed by bending both widthwise sides of the conduction portion 22 to the surface side.

  The distance between the upper end portion 25a of the folded portion 25 and the intermediate wall portion 23 is set to a value slightly smaller than the vertical dimension of the diode D described above (the dimension of the package 31 described below). On the surface side, a fuchlin 27 that can contact the end of the diode D is formed to protrude.

  As shown in FIG. 3, the diode D includes a block-shaped package 31, and includes a pair of leads 32 protruding laterally from the package 31 and a plate terminal 33 on the back surface side of the package 31. The pair of leads 32 corresponds to the anode, and the plate terminal 33 corresponds to the cathode.

〔assembly〕
With this configuration, when assembling the terminal box, the coverings 12 at the ends of the positive power cable Ea and the negative power cable Eb are removed to expose the conductors 11, Then clamp the clamper 18 in place. In this state, each power cable E may be temporarily inserted into the cable support portion Ac using the spacer 19. In addition, you may select any of 1st cable support part Ac1 and 2nd cable support part Ac2 as cable support part Ac.

  A diode D is connected between adjacent terminals among the plurality of terminal boards C. When this connection is made, the package 31 of the diode D is disposed at a position sandwiched between the upper end portion 25a of the folded portion 25 of the terminal plate C and the intermediate wall portion 23, and at the same time, the protruding end of the plate terminal 33 is connected to the fuchlin 27. The diode D is positioned by contacting with. Also, in this positioning state, the package 31 of the diode D comes into light contact with the upper end portion 25a of the folded portion 25 of the terminal plate C and the intermediate wall portion 23, whereby the positioning accuracy of the diode D is improved, and the diode D The trouble of holding D is also unnecessary.

  Thus, with the diode D supported by the terminal plate C, the plate terminal 33 is connected to the surface of the displacement portion 24 of the terminal plate C by solder or the like, and the end portion of the lead 32 is displaced by the displacement portion of the adjacent terminal plate C. The surface of 24 is connected by solder. The lead 32 can be cut and adjusted in length if necessary, or can be bent.

  Next, a plurality (four) of terminal boards C connected by the diode D are fitted into the corresponding fitting openings T. Thus, when the terminal plate C is fitted into the fitting opening T, the fitting projection 6 is fitted into the slit 26 of the terminal plate C, and the intermediate wall portion 23 is placed below the horizontal frame 4. It will be pushed in. When the fitting is completed, the fitting protrusion 6 is fitted into the slit 26, whereby the displacement of this portion (the portion on the other end side of the terminal plate C) in the thickness direction of the box body A is regulated. At the same time, when the displacement portion 24 of the terminal plate C is fitted into the fitting opening T, the displacement in the vertical direction and the horizontal direction is restricted. In particular, the position of the terminal plate C is also regulated when the bent piece 22a in which the conducting portion 22 of the terminal plate C is formed contacts the regulating portion 4R.

  In this state, the extension piece 21 is bent to the back surface side, so that the extension piece 21 comes into pressure contact with the opening edge 4S of the main opening S of the horizontal frame 4 as shown in FIG. Thereby, the displacement of the one end side of the terminal board C in the thickness direction of the box body A is restricted, and as a result, the terminal board C is completely supported by the box body A, and the surface side of the terminal board C is Is prevented from rising, moving in the vertical direction, and moving in the horizontal direction.

  Thereafter, the positive power cable Ea and the negative power cable Eb are fixed at appropriate positions, and the conducting wire 11 of the power cable E is electrically connected to the surface of the folded portion 25 of the terminal plate C by soldering or caulking. Thereafter, a part where the power line F and the terminal plate C are connected by welding or solder, a connection part between the diode D and the terminal board C, a connection part between the conductor 11 of the power cable E and the terminal board C, and the like. Filling the circuit component with a filler such as resin (potting), and further fitting the cover plate B into the box-like wall 1 allows the outer periphery of the cover plate B to be fitted into the inner circumference of the box-like wall 1 and opening The space As is closed.

  These operations are assumed to be performed on the terminal box production line, but can also be performed together with the construction of installing the solar cell module. As described above, regardless of whether the power cable E is supported by the first cable support portion Ac1 or the second cable support portion Ac2, the relative position between the conductor 11 of the power cable E and the folded portion 25 of the terminal plate C. Since the relationship (the relationship in the thickness direction) hardly changes, a good connection state is maintained.

  The terminal box assembled in this way is disposed relatively near the solar cell module when the solar cell module is installed. In addition, the power lines F from the plurality of solar cell modules are drawn into the terminal box from the main opening S, and the leading ends thereof are connected to the conduction portion 22 by soldering, caulking, or the like.

  Thus, according to the present invention, when the terminal plate C is supported by the box body A, the slit 26 (engagement portion) at the other end of the terminal plate C is connected to the fitting protrusion 6 (engaged) of the box body A. Engagement portion), the displacement portion 24 is fitted into the fitting opening T (fitting portion), the extension piece 21 at one end of the terminal board C is bent, and the opening edge 4S (bonded portion) of the horizontal frame 4 is bent. The terminal board C can be supported in a state in which the terminal board C can hardly be displaced with respect to the box body A. In particular, the crimping state is created by bending the extension piece 21 when supporting in this manner, so that even if there is a slight error between the terminal board C and the box body A, it is not affected by the error. Thus, the terminal plate C can be supported. In addition, by disposing the diode D in the displacement portion 24 that is at a lower level in the thickness direction than the conduction portion 22, not only the protrusion of the diode D is suppressed and the thickness of the terminal box is reduced, but also the overall size is reduced. Has also been realized.

  Further, since the diode D comes into contact with the terminal plate C on a wide surface, the heat generated by the diode D can be transmitted to the terminal plate C to be radiated. Since the displacement part 24 with which the diode D is provided among the terminal boards C is exposed to the back surface side of the terminal box through the fitting opening T, favorable heat dissipation is realized. In particular, when the solar cell module terminal box is disposed in contact with the lower surface of the solar cell module, the heat of the terminal plate C is transmitted to the solar cell module on the back surface side, thereby realizing better heat dissipation. .

[Another embodiment]
The present invention may be configured as follows in addition to the embodiment described above.

(A) A structure is adopted in which a protruding body is formed as an engaging portion on the other end side of the terminal board C, and a concave portion as an engaged portion into which the protruding body is fitted is formed inside the box body A. When such a structure is adopted, it is not necessary to form a folded portion on the other end side of the terminal board C. Moreover, the shape and number of a protrusion and a recessed part can be set arbitrarily.

(B) As a fitting part, it replaces with the fitting opening formed in the hole shape, and forms as a concave hollow. By forming such a concave shape, a wall portion is created on the back side of the box body A, and the strength can be improved.
