JP-A-11-204153

  In the technique of Patent Document 1, the support piece for fixing the cable is formed not on the cable side but on the panel side to which the solar cell is attached. And in the operation | work which attaches a cable to a panel, it is necessary to perform complicated processes, such as a bending raising process and a rounding process, with respect to a support piece.

  Moreover, in the technique of patent document 1, the crimping connection part of a terminal and a core wire is exposed, and it is desirable that the crimping connection part is covered from a viewpoint of insulation improvement and damage prevention.

  Therefore, an object of the present invention is to provide a connector in which a cable can be easily attached to a base portion and the crimping portion is covered.

  In order to solve the above-described problems, a connector according to the present invention is a connector for connecting a cable to a semiconductor element, and electrically connects a conductor of the cable and an electrode of the semiconductor element. And a housing fixed to the base portion arranged so as not to move with respect to the position of the semiconductor element. The housing includes a housing main body portion that supports the terminal, and a flange portion that protrudes from the housing main body portion in a direction along the surface of the base portion, and the terminal includes the housing main body portion. A crimping part housed inside and crimped and connected to the conducting wire; and a connecting part that goes out of the housing body and is electrically connected to the electrode; and Is formed with a fixing hole along a direction perpendicular to the surface of the base portion.

  In this configuration, the terminal is crimped and connected to the cable conductor, the terminal is supported by the housing body, and the housing is fixed to the base. Therefore, it is possible to prevent the cable and the terminal from being separated from the base portion. In addition, a fixing hole is formed in the flange portion, and the housing is fixed to the base portion using a connecting component such as a screw. As described above, according to this configuration, the cable connected to the semiconductor element can be easily attached to the base portion.

  Moreover, according to this structure, since the crimping | compression-bonding part is covered with a housing main-body part, the insulation state of a terminal improves compared with the case where the crimping | compression-bonding part is exposed. Furthermore, since the housing main body functions as a terminal cover, damage to the terminals can be prevented.

  The “electrode of the semiconductor element” may be any electrode that is electrically connected to the semiconductor element. Therefore, the electrode may be directly connected to the semiconductor element, or may be connected to the semiconductor element via an electric wire or the like. Moreover, the connection part of a terminal may be directly connected with respect to the electrode of a semiconductor element, and may be connected via an electric wire etc.

  In addition, “clamping connection” is a technique for fixing and connecting both wires and terminals by applying pressure to them. That is, the terminal in this configuration is a kind of a crimp-type terminal or a solderless terminal.

  Further, the phrase “supporting” the terminal by the housing main body indicates that the terminal is supported by the housing main body so that the terminal is not separated from the electrode.

  The “flange portion” is a portion protruding in a hook shape from the housing main body portion. The flange portion may be formed so as to surround the housing main body portion in plan view, or may be formed in a part of the periphery of the housing main body portion.

  The “fixing hole” is a hole for fixing the housing body to the base using a connecting component. Here, the connecting component only needs to be capable of fixing the housing to the base portion through the housing fixing hole. As the connecting component, a rivet, a nail, a pin, or the like can be used in addition to a screw. Further, the “fixing hole” includes both those having a screw groove formed therein (screw hole) and those having no screw groove formed therein. In addition, a metal spacer (collar; cylindrical member for adjusting the dimensional accuracy in the thickness direction), a metal female screw (cylindrical member whose screw groove is managed on the inner surface), etc. are fitted into the fixing hole. Thus, the strength around the hole may be improved.

  As for the cable conductors, one cable may include a plurality of conductors, or one cable may include one conductor. The cable conductor is covered with an insulator (polyolefin, polyvinyl chloride, fluororesin, polyester, heat-resistant vinyl, silicon rubber, etc.). As the polyolefin, polyethylene, polypropylene, and the like can be used.

  Further, regarding the positional relationship between the base portion and the semiconductor element, for example, the semiconductor element may be directly disposed on the base portion, or another member may be sandwiched between the base portion and the semiconductor element. Good. Further, the housing may be fixed to the front side of the base part, and the semiconductor element may be arranged on the back side of the base part. In this case, for example, a through hole may be formed in the panel, and the connection portion of the terminal may be connected to the electrode of the semiconductor element through the through hole. Further, the semiconductor element may not be disposed on the base portion, and the base on which the semiconductor element is disposed and the base portion to which the housing is fixed may be separate members. Moreover, as a semiconductor element, a solar cell can be used, for example.

  The connector which concerns on this invention WHEREIN: The protrusion part is formed in the bottom part of the said housing main-body part, The said protrusion part may fit in the recessed part formed in the said base part.

  According to this configuration, since the projecting portion fits into the recess formed in the base portion, the housing can be positioned before the housing is fixed to the base portion in the connection work (work for connecting the cable to the semiconductor element). Further, the rotation of the housing in the base portion is prevented by the two of the connecting member and the protruding portion. Further, it is possible to prevent the force due to the twist of the electric wire from being transmitted to the contact portion of the terminal.

  In the connector according to the present invention, the terminal is formed with a retaining hole, the housing main body part is formed with a hooking part, and the hooking part is hooked into the retaining hole. Also good.

  According to this configuration, since the hook portion is hooked in the retaining hole, it is possible to prevent the terminal from coming out of the housing. The retaining hole only needs to be formed so that the hooking part is caught, and may be a through hole or a hole that is not formed through.

  In the connector according to the present invention, a flat plate portion formed in a flat plate shape is formed on the terminal between the crimping portion and the connection portion, and the flat plate portion is sandwiched between the housing main body portions. May be supported.

  When the cable is rotated (twisted; rolled) in the circumferential direction of the cable, if the rotation is transmitted to the terminal connection portion, the connection between the cable and the semiconductor element may be affected. Therefore, according to this configuration, (i) the flat plate portion is sandwiched and supported by the housing main body portion. Further, (ii) the housing is fixed to the base portion. As described above, even if the cable is rotated, the rotation of the cable is not transmitted to the connection portion of the terminal, so that the connection state between the cable and the semiconductor element can be maintained.

  In the connector according to the present invention, a guide groove for guiding the terminal to the mounting position is formed inside the housing main body, and the guide groove has an end in the width direction of the flat plate. In the fitting position, the flat plate portion may be sandwiched and supported in the guide groove portion.

  According to this configuration, since the terminal has only to be inserted along the guide groove when the terminal is attached, the terminal can be easily arranged at the attachment position. In addition, two guide groove portions may be formed inside the housing main body portion so as to be supported by sandwiching the flat plate portion at both end portions of the flat plate portion, or at one end portion of the flat plate portion. One guide groove portion may be formed so as to be supported with the gap interposed therebetween.

  In the connector according to the present invention, the housing main body portion is formed with a first wall and a second wall that support the flat plate portion sandwiched from both sides, and the guide groove portion includes the first wall and the first wall. A first end and a second end are formed on the first wall and the second wall, respectively, on the rear side with respect to the mounting direction of the terminal. The position of the one end portion and the second end portion may be different with respect to the attachment direction. According to this configuration, the terminal is smoothly inserted forward of the first end and the second end when the terminal is attached.

  The connector which concerns on this invention WHEREIN: The inclined surface is formed in the edge part which faces the said connection part of the upper surface part of the said housing main-body part, The height from the said base part of the said inclined surface is the said connection part. It may be lowered as it approaches the department. According to this configuration, the space for assembling the connector can be widened. For example, when the connecting portion and the electrode are soldered using a soldering iron, the range of the angle at which the soldering iron is tilted can be expanded.

  The upper surface portion of the housing main body portion is an upper surface portion when the housing is the upper side and the base portion is the lower side in a state where the housing is fixed to the base portion. Further, the end facing the connection portion is an end closest to the connection portion among the end portions of the upper surface portion in the top view of the housing.

  In the connector according to the present invention, the terminal may be made of oxygen-free copper. According to this structure, since the electrical conductivity of a terminal becomes high, the efficiency of the electrical conduction between a semiconductor element and a cable improves. As the oxygen-free copper, for example, a material conforming to the symbol C1020 defined in JIS H3100, or a material having the same quality as this can be used.

And in the connector 1, the hook part 51c is hooked in the retaining hole 43h (refer FIG.3 and FIG.4 (b)). Specifically, the hook surface 51z of the hook portion 51c and the inner wall surface of the retaining hole 43h face each other with respect to the mounting direction G. As a result, the movement of the terminal 4 in the mounting direction G is limited.

  The housing body 51 has a bottom plate portion 51b formed in a plate shape (see FIGS. 3 and 12B). A pedestal 51o is formed on the bottom of the bottom plate 51b so as to protrude (see FIGS. 3, 11, and 12). The pedestal 51o is provided at the center of the housing main body 51 with respect to the mounting direction G (see FIGS. 3 and 11).

As described above, the protrusion 51 t is formed on the bottom of the housing body 51. In addition, four holes are formed in the pedestal portion 51o so as to surround the protruding portion 51t (see FIG. 11).

  In a state where the housing main body 51 is attached to the metal base 71, the protrusion 51t fits into the recess 71c formed in the metal base 71 (see FIG. 3). The recess 71c has a circular cross-sectional contour shape (in the plan view, the recess 71c is circular). Further, the size of the recess 71c is substantially equal to the size of the hook portion 51c.

  An inclined surface 51e is formed on the upper surface of the housing body 51 (see FIG. 2). The inclined surface 51e is formed in parallel with the direction inclined in the attachment direction G between the upper surface 53a of the housing body 51 and the surface 53b on the G1 side of the housing body 51. Further, the inclined surface 51 e is formed at an end portion facing the connection portion 42 among the end portions of the upper surface portion of the housing main body portion 51. Further, the height of the inclined surface 51e from the metal base 71 becomes lower as it approaches the connecting portion 42. Since the inclined surface 51e is formed in the housing main body 51, the space for assembling the connector 1 is widened as compared with the case where the housing shape is a rectangular parallelepiped shape. Therefore, in the operation of soldering the connection portion 42 and the electrode 21, the range of the angle at which the soldering iron is inclined is widened. Moreover, the field of view in the assembly work of the connector 1 including the solder connection work is expanded.

(Flange part)
The flange portion 52 protrudes from the housing main body portion 51 in a bowl shape (see FIGS. 9, 12 (a), 12 (c), and 12 (d)). Further, the flange portion 52 protrudes in a direction along the surface of the metal base 71 in a state where the housing 5 is fixed to the metal base 71 (see FIG. 1).

  In addition, a fixing hole 52h is formed through the flange portion 52 (see FIGS. 9, 11, and 12A). The fixing hole 52h is formed along a direction perpendicular to the surface of the metal table 71 when the housing 5 is fixed to the metal table 71 (see FIG. 1). The fixing hole 52h is used for fixing the housing main body portion to the base portion using a screw (connection component) 6 (see FIG. 1). Moreover, four holes are formed in the bottom part of the flange part 52 so that the fixing hole 52h may be enclosed (refer FIG. 11). Further, the bottom surface of the flange portion 52 and the bottom surface of the pedestal portion 51o are located on the same plane (see FIGS. 11, 12C, and 12D).

(Waterproof rubber)
Next, the waterproof rubber will be described. FIG. 13 is a schematic view of a waterproof rubber, wherein (a) is a perspective view, (b) is a front view, and (c) is a plan view. The waterproof rubber 8 functions as a lid member for the housing body 51, and the waterproof rubber 8 is made of silicon rubber. The outline shape of the waterproof rubber 8 is substantially quadrangular when viewed from the front. Two grooves are formed in a side portion of the waterproof rubber 8 along a direction perpendicular to the mounting direction G. Further, a through hole 8h through which the cable 3 is passed is formed at the center of the waterproof rubber 8 (see FIGS. 3 and 13).

(About connector assembly work)
Next, the assembly work of the connector 1 will be described. First, the cable 3 is passed through the through hole 8 h of the waterproof rubber 8 in advance. Then, the terminal 4p is crimped and connected to the plurality of conducting wires 31 of the cable 3 (crimping step; see FIG. 8). Specifically, a plurality of conducting wires 31 are inserted into the crimping part 41p, and the crimping part 41p is deformed by applying pressure using a crimping tool.

  Next, the terminal 4 and the cable 3 after the crimping connection are attached to the housing 5 (terminal attachment process). Hereinafter, this process will be specifically described. First, the terminal 4 is inserted into the housing main body 51 from the second opening 51n. At this time, both end portions of the flat plate portion 43 are fitted into the two reinforcing guide portions 51p. When the terminal 4 is slid and inserted into the housing main body 51, the flat plate portion 43 reaches the positions of the first end 51j and the second end 51k. Here, since the positions of the first end portion 51j and the second end portion 51k in the mounting direction G are different, the flat plate portion 43 is not caught by the first end portion 51j or the second end portion 51k, and the guide groove portion 51g. It is inserted smoothly. When the terminal 4 is further inserted, the terminal 4 reaches the attachment position. By the time the terminal 4 reaches the mounting position, the connecting portion 42 of the terminal 4 is taken out from the first opening 51m, and the hook portion 51c and the connecting portion 44 are in contact with each other, so that the arm portion 51a is Elastically flexes upward. Specifically, when the curved surface of the hook portion 51c and the connecting portion 44 come into contact with each other, the arm portion 51a rides on the terminal 4 without the terminal 4 being hooked on the hook portion 51c. And in the attachment position of the terminal 4, the both ends of the flat plate part 43 will be fitted in each guide groove part 51g, and it will be in the state by which the hook part 51c was hooked in the retaining hole 43h. In this state, the hooking surface 51z and the inner wall surface of the retaining hole 43h face each other. In this way, the terminal 4 is attached to the housing main body 51 so as not to come out of the housing 5.

  Next, the waterproof rubber 8 is attached to the housing 5 (waterproof rubber attaching step). Hereinafter, this process will be specifically described. As described above, the cable 3 is passed through the through hole 8h of the waterproof rubber 8 in advance. Then, after the terminal attaching step, the waterproof rubber 8 is slid along the cable 3 and fitted into the second opening 51 n of the housing body 51. In this way, the connector 1 is assembled (see FIG. 2).

(About assembled connectors)
Next, the connector 1 assembled as described above will be described. In the connector 1, of the terminals 4, the connecting portion 42 and the connecting portion 44 protrude to the outside of the housing main body 51, and the flat plate portion 43 and the crimping portion 41 are covered with the housing main body 51 (see FIG. 2, see FIGS. 3 and 4). An internal space 51s is formed inside the connector 1 (see FIGS. 3 and 4A).

  Further, in the assembled connector 1, the terminals 4 are attached to the housing main body 51 so as not to come out of the housing main body 51. Therefore, for example, even if the connector 1 and the cable 3 are transported, the connector 1 is not disassembled and the assembled state can be maintained.

  In the connector 1, the waterproof rubber 8 and the inner surface of the opening wall 51r are in close contact with each other, and the second opening 51n is closed.

(About connection work)
Next, connection work (work for connecting the cable 3 to the solar cell 2) will be described. Specifically, in this connection work, the connector 1 (the connector 1 with the cable 3 attached) after the assembly work is connected to the metal base 71 and the electrode 21.

  First, the housing 5 is installed on the metal base 71 so that the protrusion 51t fits into the recess 71c (positioning step). Thereby, the position in the metal stand 71 of the connector 1 is decided.

  Next, the housing 5 is screwed to the metal base 71 using the screws 6 (screwing process). By this step, the orientation of the connector 1 is determined. In addition, after this process has elapsed, the connection portion 42 contacts the electrode 21. Then, the rotation of the housing 5 is prevented by the two of the screw 6 and the protruding portion 51t.

  Next, the connection part 42 and the electrode 21 are connected by soldering (soldering process). Since the connecting portion 42 is flat, a solder fillet is widely formed around the connecting portion 42. Further, since the through hole 42h is formed in the connecting portion 42, the solder enters the through hole 42h. As a result of these, the connecting portion 42 and the electrode 21 are reliably connected. As described above, the cable 3 is connected to the solar cell 2.

(About removal work)
Next, an operation for removing the connector 1 will be described. First, the screw 6 is removed from the housing 5. Next, the solder of the connecting portion 42 is heated to melt the solder, and the housing 5 is removed from the metal base 71. At this time, the connecting portion 42 is detached from the electrode 21. As described above, in the connector 1, the cable 3 and the terminal 4 can be removed when it is necessary to remove them. Therefore, it is possible to replace (or repair) the cable 3 or the terminal 4 so that the cable 3, the terminal 4, the printed board 72, and the metal base 71 are not damaged.

(About terminal protection)
Moreover, the waterproof performance of the connector 1 can be improved by protecting the terminal 4 as follows. After fixing the connector 1 to the metal base 71, the internal space 51s is filled with an adhesive (sealant). Furthermore, the periphery of the connecting portion 42 that is outside the housing 5 is covered with an adhesive (see D portion surrounded by a broken line in FIG. 3). And since the 1st opening part 51m is covered with an adhesive agent, permeation of water etc. from the 1st opening part 51m to the inside of the housing main-body part 51 is prevented. Thereby, the watertightness and airtightness inside the connector 1 are improved. Moreover, the connection part 42 and the crimping | compression-bonding part 41 are protected with an adhesive agent. As the adhesive, a silicone adhesive, an epoxy resin adhesive, a urethane resin adhesive, or the like can be used. Moreover, as an adhesive (sealant), a highly insulating and flame retardant material is desirable.

(effect)
Next, the effect of the connector 1 according to the present embodiment will be described. The connector 1 is for connecting the cable 3 to the solar cell 2, and includes a terminal 4 for electrically connecting a plurality of conductive wires 31 of the cable 3 and the electrode 21 of the solar cell 2, and the solar cell 2. And a housing 5 that is fixed to a metal base (base portion) 71 that is arranged so as not to move relative to the position. The housing 5 includes a housing main body 51 that supports the terminal 4 and a flange 52 that protrudes from the housing main body 51 in a direction along the surface of the metal base 71. The terminal 4 includes the housing main body 51. A crimping part 41 accommodated inside 51 and crimped and connected to a plurality of conductors 31; and a connection part 42 that goes out of the housing body 51 and is electrically connected to the electrode 21. The flange portion 52 is formed with a fixing hole 52h along a direction perpendicular to the surface of the metal base 71.

  According to this configuration, the terminal 4 is crimped and connected to the plurality of conducting wires 31 of the cable 3, the terminal 4 is supported by the housing body 51, and the housing 5 is fixed to the metal base 71. Therefore, separation between the cable 3 and the terminal 4 and the metal base 71 can be prevented. In addition, a fixing hole 52 h is formed in the flange portion 52, and the housing 5 is fixed to the metal base 71 using screws 6. As described above, according to this configuration, the cable 3 connected to the solar cell 2 can be easily attached to the metal base 71.

  Moreover, according to this structure, since the crimping | compression-bonding part 41 is covered with the housing main-body part 51, the insulation state of the terminal 4 improves compared with the case where the crimping | compression-bonding part 41 is exposed. Moreover, since the housing main body 51 functions as a cover for the terminal 4, damage to the terminal 4 can be prevented.

  In the connector 1, a protrusion 51 t is formed at the bottom of the housing body 51, and the protrusion 51 t fits into a recess 71 c formed on the metal base 71.

  According to this configuration, since the protruding portion 51t is fitted into the recess 71c formed in the metal base 71, the housing 5 can be positioned before the housing 5 is fixed to the metal base 71 in the connection work. Moreover, rotation of the housing 5 in the metal base 71 is prevented by the two of the screw 6 and the protruding portion 51t.

  Further, in the connector 1, the terminal 4 is formed with a retaining hole 43h, the housing main body 51 is formed with a hooking part 51c, and the hooking part 51c is hooked into the retaining hole 43h. .

  According to this configuration, since the hook portion 51c is hooked in the retaining hole 43h, it is possible to prevent the terminal 4 from slipping out of the housing 5.

  Further, in the connector 1, a flat plate portion 43 formed in a flat plate shape is formed on the terminal 4 between the crimping portion 41 and the connection portion 42, and the flat plate portion 43 is sandwiched between the housing main body portions 51. Supported.

  When the cable rotates (rolls) in the circumferential direction of the cable, if the rotation is transmitted to the terminal connection portion, the connection between the cable and the solar cell may be affected. Therefore, according to this configuration, (i) the flat plate portion 43 is sandwiched and supported by the housing body portion 51. Further, (ii) the housing 5 is fixed to the metal base 71. As described above, even if the cable 3 rotates, the rotation of the cable 3 is not transmitted to the connection portion 42 of the terminal 4, so that the connection state between the cable 3 and the solar cell 2 can be maintained.

  Further, in the connector 1, two guide groove portions 51 g for guiding the terminals 4 to the mounting position are formed inside the housing main body portion 51. The two guide groove portions 51 g have the width of the flat plate portion 43. Both end portions in the direction W are fitted, and the flat plate portion 43 is sandwiched and supported in each guide groove portion 51g at the attachment position.

  According to this configuration, when the terminal 4 is attached, it is only necessary to insert the terminal 4 along the two guide groove portions 51g, so that the terminal 4 can be easily arranged at the attachment position.

  Further, in the connector 1, the housing main body 51 is formed with two first walls 51d and two second walls 51f that support the flat plate portion 43 from both sides, and two guide groove portions 51g. Is formed between two first walls 51d and two second walls 51f. The first wall 51d and the second wall 51f are respectively provided with a first end 51j and a second end 51k on the rear side with respect to the mounting direction of the terminal 4, and the first end 51j and the second wall 51f The positions of the two end portions 51k are different with respect to the mounting direction. According to this configuration, when the terminal 4 is attached, the terminal 4 is smoothly inserted forward of the first end 51j and the second end 51k.

  In the connector 1, an inclined surface 51 e is formed at an end of the upper surface portion of the housing main body 51 facing the connection portion 42, and the height of the inclined surface 51 e from the metal base 71 is determined by the connection portion. It gets lower as you get closer. According to this configuration, the space for assembling the connector can be widened. For example, when the connecting portion 42 and the electrode 21 are solder-connected using a soldering iron, the range of the angle at which the soldering iron is tilted can be expanded.

  In the connector 1, the terminal 4 is made of oxygen-free copper. According to this configuration, since the electrical conductivity of the terminal 4 is increased, the efficiency of electrical conduction between the solar cell 2 and the cable 3 is improved.

  In the connector 1, the connecting component is a screw 6. According to this configuration, the housing 5 is fixed to the metal base 71 by screwing. Thereby, when removing the cable 3 and the terminal 4 for maintenance, replacement, etc., the housing 5 can be easily removed from the metal base 71. That is, with this configuration, the cable 3 connected to the solar cell 2 can be easily detached.

  In the connector 1, the terminal 4 is attached to the housing main body 51 so that the terminal 4 does not come out of the housing main body 51 before the housing 5 is attached to the metal base 71.

  According to this configuration, the assembly of the connector 1 can be completed before the cable 3 and the solar cell 2 are connected. Therefore, the person who performs the connection work does not need to perform the work of assembling the connector 1, (i) work for fixing the housing 5 to the metal base 71, and (ii) connection of the connection part 42 and the electrode 21 Just do the work.

  In the present embodiment, a screw hole (not shown) and a recess 71 c may be formed in the metal base 71 when the solar cell 2 and the cable 3 are attached. And the screw hole and the recessed part 71c can be formed easily. As a result, by using the connector 1, it is not necessary to perform complicated processing on the metal base 71 in order to attach the cable 3 to the solar cell 2. In addition, since the cable 3 can be connected to the solar cell 2 by a simple operation, incomplete connection hardly occurs in the connection operation, and a reliable connection is performed.

  In the state where the cable 3 and the solar cell 2 are connected, (i) the housing 5 is fixed to the metal base 71, (ii) the flat plate portion 43 is supported by the two guide groove portions 51g, (Iii) The hook portion 51c is hooked in the retaining hole 43h. Therefore, according to the configuration of the connector 1, the terminal 4 is not separated from the electrode 21 in a state where the cable 3 and the solar cell 2 are connected.
