The connector of the 2 division | segmentation structure with the female side connector part provided with the 2nd terminal housing to accommodate is provided (for example, refer patent document 1).

  In recent years, such eco-cars have been reduced in weight for all parts for the purpose of improving energy-saving performance. However, one of the effective means for reducing the weight is to reduce the size. I hit it.

  Therefore, as a known technique, for example, there is a technique as disclosed in Patent Document 2.

  The technique disclosed in Patent Document 2 is a vehicle that connects a joint terminal of a plurality of phases of conductive members drawn from a motor for driving a vehicle and a joint terminal of a plurality of phases of a power line cable drawn from an inverter that drives the motor. In the electrical connection structure for use, the joining terminal of each phase of the conductive member and the joining terminal of each phase of the corresponding power line cable are polymerized, and the insulating member is disposed on the surface opposite to the overlapping surface of the joining terminal. In this technique, the joined terminals and insulating members of each polymerized phase are fastened and fixed in the polymerizing direction by a single bolt provided at a position penetrating them.

  That is, the technique of Patent Document 2 is a method in which a single bolt is tightened in a superposition direction, and a plurality of contact points between joint terminals, which are superposed surfaces of the joint terminals, are sandwiched at a plurality of points in a lump. However, such a configuration is effective in that it can be easily reduced in size as compared with the technique disclosed in Patent Document 1.

  Furthermore, the technique of Patent Document 2 is a structure that can hold the interval between the insulating members by holding the insulating member that sandwiches the contacts of the joining terminals with a holding jig separately provided. This is effective in terms of insertion / extraction of the junction terminal.

Connect to at least each contact Portion and a connecting member 9 formed of an insulating material.

  The first housing 5 may be a male (male side housing) or a female (female side housing) as a housing. Here, the case where the 1st housing 5 is a male side housing is demonstrated as an example.

  The first joint terminals 4a to 4c are plate-like terminals, and are made of insulating resin (for example, PPS (polyphenylene sulfide) resin, PPA (polyphthalamide) resin, PA (polyamide) resin, PBT (polybutylene terephthalate), The resin molded body 10, which is a part of the first housing 5, is arranged and held at a predetermined interval. As a method of holding the first joint terminals 4a to 4c in the resin molded body 10, for example, a method of inserting the first joint terminals 4a to 4c when molding the resin molded body 10 and then curing and holding the resin, There is a method in which the first joint terminals 4a to 4c are press-fitted and held in a pre-molded resin molded body 10.

  Electricity of different voltage and / or current is transmitted to each of the first joint terminals 4a to 4c. For example, in the present embodiment, a three-phase AC power line for use between the motor and the inverter is assumed, and alternating currents having 120-phases are transmitted to each of the first junction terminals 4a to 4c. Each of the first connecting terminals 4a to 4c is preferably made of a metal having high conductivity such as silver, copper, or aluminum for the purpose of reducing power transmission loss in the connector 1 or the like.

With these configurations, the insertability of the second joint terminals 6a to 6c with respect to the first joint terminals 4a to 4c when the first connector portion 2 and the second connector portion 3 are fitted is improved. In FIG. 5, the structure of the first insulating member 8a is simplified, and the first insulating members 8a to 8c are drawn in the same manner.

  Referring to FIG. 4 again, the connection member 9 is made of an insulating material on the outer periphery of a bolt 12 made of metal (for example, SUS, iron, copper alloy, etc.) and its shaft portion 9b (including a portion penetrating each contact).

  In addition, as the connection member 9, what formed all with the insulating resin may be used, but the thing which covered the outer periphery of the axial part 9b of the metal volt | bolts 12 with the insulating layer 13 from a viewpoint of intensity | strength. It is preferred to use. In other words, the connecting member 9 is made of a fold structure of the metal bolt 12 and the insulating resin insulating layer 13, so that the strength can be increased as compared with the case where the entire connecting member 9 is formed of the insulating resin. As the insulating resin to be coated on the metal bolt 12, a resin having a linear expansion coefficient close to that of the metal constituting the bolt 12 may be used to prevent creep.

  A packing 14 that prevents water from entering the first housing 5 is provided on the outer periphery of the head portion 9 a of the connection member 9. In addition, an elastic member 15 that applies a predetermined pressing force to the first insulating member 8a is provided between the lower surface of the head 9a of the connecting member 9 and the upper surface of the first insulating member 8a immediately below the head 9a. The elastic member 15 is composed of, for example, a spring made of metal (for example, SUS). In the present embodiment, the elastic member 15 is positioned as a part of the connection member 9.

  The upper surface of the first insulating member 8a with which the lower portion of the elastic member 15 abuts is formed with a concave portion 16 that houses the lower portion of the elastic member 15, and the bottom of the concave portion 16 (that is, the seat portion with which the lower portion of the elastic member 15 abuts ) Is provided with a receiving member 17 made of metal (for example, SUS) that receives the elastic member 15 and prevents damage to the first insulating member 8a made of insulating resin.

  The connecting member 9 is inserted into the first housing 5 from the surface side (the upper surface side in FIG. 4) of the first connecting terminals 4a to 4c to which the first insulating members 8a to 8c are fixed, and the shaft portion 9b. Is screwed into a screw hole 19 formed in the inner peripheral surface of the first housing 5, so that the head 9a of the connecting member 9 is directed toward the tip of the shaft 9b (refer to FIG. 4). For example, the plurality of first connecting terminals 4a to 4c and the plurality of second connecting terminals 6a to 6c are fixed together at each contact and electrically connected.

  The first housing 5 includes a hollow cylindrical body 20 having a substantially rectangular cross section. An outer peripheral portion on one end side (right side in the drawing) of the cylindrical body 20 fitted to the second housing 7 is formed in a tapered shape in consideration of fitting properties with the second connector portion 3. A housing waterproof structure 21 that seals between the first connector portion 2 and the second connector portion 3 is provided on the outer peripheral portion on one end side of the cylindrical body 20. The waterproof housing structure 21 includes a recess 22 formed in the outer peripheral portion on the opening side of the cylindrical body 20 and a packing 23 such as an O-ring provided in the recess 22.

  The other end side (the left side in the figure) in the cylindrical body 20 accommodates the resin molded body 10 in which the first joint terminals 4a to 4c are aligned and held. A flange 24 (an attachment hole is omitted) for fixing the first connector portion 2 to a housing (for example, a shield case of a motor) such as a device is formed on the outer periphery on the other end side of the cylindrical body 20. The edge 24 of the flange 24 for inserting a bolt into the mounting hole and fixing it to the housing of the device or the like is provided with a packing or the like that seals between the housing of the device and the first connector portion 2. May be. The configuration of the flange 24 is not based on the premise that the first connector portion 2 is fixed to a housing such as a device, and the flange 24 may be provided in the second connector portion 3. It may be provided in both the first connector part 2 and the second connector part 3. Moreover, it is good also as a free state in which neither the 1st connector part 2 nor the 2nd connector part 3 is fixed to housings, such as an apparatus.

  The flange 24 is also effective in improving heat dissipation. That is, by forming the flange 24, the surface area of the first housing 5 can be increased, and heat generated inside the first connector portion 2 (for example, heat generated at each contact) is passed through the first housing. When dissipating heat to the outside, heat dissipation can be improved.

  A connection member insertion hole 26 for inserting the connection member 9 is formed in an upper portion (upper side in the drawing) of the cylindrical body 20. The connection member insertion hole 26 is formed in a cylindrical shape, and its cylindrical lower end (lower side in the figure) is bent inward. The stroke of the connecting member 9 is restricted by the edge peripheral portion of the lower surface of the head portion 9a of the connecting member 9 coming into contact with the bent portion.

  The cylindrical body 20 is preferably formed of a metal such as aluminum having high electrical conductivity and thermal conductivity in order to reduce shielding performance, heat dissipation, and weight of the connector 1, but is formed of resin or the like. You may do it. When the first housing 5 is formed of an insulating resin, the second insulating member 8d and the first housing 5 may be integrally formed of an insulating resin. In the present embodiment, the cylindrical body 20 is made of aluminum. In this way, by forming the cylindrical body 20 with aluminum, when the connection member 9 is screwed into the screw hole 19, it can be tightened more firmly than when the cylindrical body 20 is formed with an insulating resin. There is an effect.

  As shown in FIG. 6, the second connector portion 3 includes a second housing 7 in which a plurality (three) of second joining terminals (female terminals) 6 a to 6 c are arranged and stored. In addition, the connector part by the side which has a female terminal is called the 2nd connector part 3 here. That is, the second housing 7 may be a male (male side housing) or a female (female side housing) as a housing. Here, the case where the 2nd housing 7 is a female side housing corresponding to the 1st housing 5 which is a male side housing is demonstrated.

Cables 27a to 27c extending from the inverter side are connected to one end sides of the second connection terminals 6a to 6c, respectively. Since each of these cables 27a to 27c is electrically connected to each of the first joint terminals 4a to 4c via the second joint terminals 6a to 6c, the voltage corresponding to each of the first joint terminals 4a to 4c. And / or current electricity is transmitted respectively. The cables 27 a to 27 c are formed by forming an insulating layer 29 on the outer periphery of the conductor 28. In the present embodiment, the conductor 28 having a cross-sectional area of 20 mm ² is used.

  Each of the cables 27 a to 27 c is aligned and held at a predetermined interval by a cable holding member 30 having a multi-tubular shape (a state in which a plurality of tubes are connected). When the first connector part 2 and the second connector part 3 are fitted to each other, the second joining terminals 6a to 6c are paired with the second joining terminals 6a to 6c by the cable holding member 30, respectively. Thus, it positions and hold | maintains so that it may be located under each of 1st junction terminal 4a-4c which faces (namely, connection object).

  The cable holding member 30 is made of an insulating resin or the like so as to insulate the second joining terminals 6a to 6c from each other and prevent a short circuit. Even if each of the cables 27a to 27c connected to each of the second joining terminals 6a to 6c is a cable excellent in flexibility, the second holding terminals 6a to 6c are respectively predetermined by the cable holding member 30. Can be held in the position. That is, in this embodiment, since cables having excellent flexibility can be used as the cables 27a to 27c, the degree of freedom in wiring when the cables 27a to 27c are laid can be improved.

  In addition, the cable holding member 30 holds the cables 27a to 27c. More specifically, the cable holding member 30 holds the end portions of the cables 27a to 27c at positions close to the second connecting terminals 6a to 6c. The second joint terminals 6a to 6c are positioned so as to hold the two joint terminals 6a to 6c in a predetermined position, but the cables 27a to 27c are held and the second joint terminals 6a to 6c are also directly held. The positioning of the second connecting terminals 6a to 6c may be performed. Further, instead of the cable holding member 30, a joining terminal holding member that directly holds the second joining terminals 6 a to 6 c without holding the cables 27 a to 27 c may be used.

  With respect to the cable holding member 30, the second connecting terminals 6a to 6c are positioned by holding the cables 27a to 27c without directly holding the second connecting terminals 6a to 6c. In such a case, by making the cables 27 a to 27 c flexible, the distal ends of the second connection terminals 6 a to 6 c can be made flexible with respect to the second housing 7. With this configuration, in the first connector portion 2, the first connecting terminals 4 a to 4 c are deformed by the pressing of the connecting member 9, and even if the position of the portion into which the second connecting terminal is inserted slightly changes. Can respond flexibly.

  Further, a braided shield 31 is wound around the portions of the cables 27a to 27c drawn from the second housing 7 for the purpose of improving the shielding performance. The braided shield 31 is in contact with a cylindrical shield body 41 to be described later, and is electrically connected to the first housing 5 via the cylindrical shield body 41 (has the same potential (GND)).

  As shown in FIGS. 7 and 8, each of the second joining terminals 6 a to 6 c is formed integrally with the caulking portion 32 and the caulking portion 32 for caulking the conductor 28 exposed from the distal ends of the cables 27 a to 27 c. And a U-shaped contact 33. A tapered portion 34 is formed at the tip of the U-shaped contact 33 in order to improve the insertability. When the first connector portion 2 and the second connector portion 3 are fitted, the U-shaped contact 33 is inserted so as to sandwich the shaft portion 9b of the connecting member 9.

  In the present embodiment, in order to reduce the size of the connector 1, the cables 27a to 27c are arranged and held with as little gap as possible. Therefore, as shown in FIG. 8, the second joint terminals 6a to 6c are spaced apart at the same interval by bending the body portion 35 of the second joint terminal 6b connected to the cable 27b disposed at the center during alignment. It was arranged.

  Each of the second connection terminals 6a to 6c is preferably made of a metal such as silver, copper, or aluminum having high conductivity for the purpose of reducing power transmission loss in the connector 1 or the like. Moreover, each of the 2nd junction terminals 6a-6c has some flexibility.

  Referring to FIG. 6 again, the second housing 7 includes a hollow cylindrical body 36 having a substantially rectangular cross section. Since the first housing 5 is fitted into the second housing 7, the inner peripheral portion on one end side (the left side in the drawing) of the cylindrical body 36 fitted with the first housing 5 is fitted with the first housing 5. It is formed in a tapered shape in consideration of compatibility.

  Conversely, the second housing 7 may be fitted into the first housing 5. In this case, the inner peripheral portion on one end side of the cylindrical body 20 constituting the first housing 5 is formed in a tapered shape, and the outer peripheral portion on one end side of the cylindrical body 36 constituting the second housing 7 is formed in a tapered shape. The housing waterproof structure 21 may be formed on the outer peripheral portion on one end side of the cylindrical body 36.

  A cable holding member 30 that holds and aligns the cables 27a to 27c is housed on the other end side (the right side in the figure) of the cylindrical body 36. A packingless airtight portion 37 is formed on the cable insertion side of the cable holding member 30 so as to prevent water from entering the second housing 7 along the cables 27a to 27c. A packing 38 that abuts against the inner peripheral surface of the first housing 5 is provided on the outer peripheral portion of the cable holding member 30. That is, the connector 1 has a double waterproof structure by the packing 23 provided on the outer periphery of the packing 23 of the housing waterproof structure 21 and the cable holding member 30.

  Further, a rubber boot 39 for preventing water from entering the cylindrical body 36 is covered on the outer periphery of the cylindrical body 36 from which the cables 27a to 27c are drawn.

  Further, when the second connector part 3 and the first connector part 2 are fitted to the upper part (the upper side in the figure) of the cylindrical body 36, the connection member 9 provided in the first connector part 2 is operated. The connection member operation hole 40 is formed.

And is electrically and electrically connected to the first housing 5. Thereby, the shielding performance and heat dissipation are improved. In particular, with regard to heat dissipation, significant improvement is expected by positively releasing heat to the first housing 5 side, which is excellent in heat dissipation.

  Next, connection between the first joint terminals 4a to 4c and the second joint terminals 6a to 6c using the connector 1 according to the present embodiment will be described.

  When the 1st connector part 2 and the 2nd connector part 3 are fitted, each of 2nd junction terminal 6a-6c is between each of 1st junction terminal 4a-4c used as a pair, and insulation member 8a-8d.

And by this insertion, while facing each of one surface of several 1st junction terminals 4a-4c and each of one surface of several 2nd junction terminals 6a-6c, it is 1st junction terminal 4a-. 4c, the 2nd junction terminals 6a-6c, and the insulating members 8a-8d will be in the laminated state arrange | positioned alternately.

  At this time, inside the first connector portion 2, the insulating members 8a to 8c are fixed to the distal ends of the first connection terminals 4a to 4c that are held in alignment with being separated at a predetermined interval. Therefore, the interval between the insulating members 8a to 8c can be maintained without separately providing a holding jig for holding the interval between the insulating members 8a to 8c. Thereby, each of the 2nd junction terminals 6a-6c can be easily inserted between each of the 1st junction terminals 4a-4c used as a pair, and insulating member 8a-8d. That is, the insertability of the second connection terminals 6a to 6c is not lowered. In addition, since it is not necessary to provide a holding jig for holding the interval between the insulating members 8a to 8c, it is very effective in that further downsizing can be realized as compared with the related art.

  In addition, the first insulating member 8a (or the contact of the first joint terminal 4a (or 4b) and the second joint terminal 6a (or 6b) is fixed to the first joint terminal 4a (or 4b) constituting the contact. 8b) and the first insulating member 8b (or 8c) fixed to the first joint terminal 4b (or 4c) constituting another contact. Similarly, the first contact terminal 4c and the second contact terminal 6c are connected to the first insulation member 8c fixed to the first connection terminal 4c constituting the contact and the second contact fixed to the inner surface of the first housing 5. It is sandwiched between the insulating members 8d.

  Thereafter, as shown in FIG. 3, when the connection member 9 is operated from the connection member operation hole 40 and the screw portion 18 of the connection member 9 is screwed into the screw hole 19 of the first housing 5 and tightened, the connection member 9 is pushed into the bottom of the screw hole 19 while being rotated, and is pressed by the elastic member 15 in the order of the first insulating member 8a, the first insulating member 8b, the first insulating member 8c, and the second insulating member 8d. Are pressed so as to be sandwiched by any two of the insulating members 8a to 8d, and the contact points are in contact with each other while being insulated from each other. At this time, each of the first joint terminals 4a to 4c and each of the second joint terminals 6a to 6c are slightly bent by the pressing from the insulating members 8a to 8d and are brought into contact in a wide range. As a result, each contact point is firmly contacted and fixed even in an environment such as a vehicle that generates vibrations. Thereby, it is possible to realize a particularly effective connector for an automobile in which vibration is likely to occur.

  In the present embodiment, each of the first joint terminals 4a to 4c and each of the second joint terminals 6a to 6c are in contact with each other on the surface, but the second joint terminal is a contact-side surface. A configuration is also possible in which a convex portion is formed on each of the surfaces of the first joint terminals 4a to 4c that come into contact with each of 6a to 6c, and the U-shaped contact 33 of the second joint terminals 6a to 6c is fitted into the convex portion. good. By comprising in this way, the coupling | bonding force with each of 1st junction terminal 4a-4c and each of 2nd junction terminal 6a-6c can be stabilized further. That is, it is particularly effective against vibration in the direction perpendicular to the connection member 9.

  Further, in the present embodiment, the lengths of the branched tips of the U-shaped contacts 33 of the second connection terminals 6a to 6c are the same length, but either one of the lengths is formed to be long. It may be a letter contact. By adopting a shape like a J-shaped contact, the second connector portion 3 can be inserted into the shaft portion 9b of the connecting member 9 even from an oblique direction with respect to the cable longitudinal direction.

  In the present embodiment, the screw hole 19 is formed at a position such that the screw hole 19 is screwed with the screw portion 18 on the distal end side of the connection member 9, but the screw portion 18 on the head 9 a side of the connection member 9. The screw hole 19 may be formed so as to be screwed with the screw portion 18 formed on the head 9a side.

  Further, for example, in the present embodiment, the screw hole 19 is formed on the first housing 5 side. However, the first housing 5 side is not the screw hole 19 but only the through hole. 2 may be formed on the housing 7 side. Moreover, the screw hole 19 may be formed over both the first housing 5 side and the second housing 7 side.

  Although the connector 1 according to the first embodiment has been described above, as one of the features of the connector 1 according to the first embodiment, unlike the connector 100 according to the second embodiment described later, the shaft portion of the connecting member 9 9b passes through the respective contact points and the plurality of insulating members 8a to 8d according to the plurality of first joining terminals 4a to 4c and the plurality of second joining terminals 6a to 6c. By comprising in this way, in the fitting state of the 1st connector part 2 and the 2nd connector part 3, centering on the connection member 9, it is the 1st junction terminals 4a-4c and the 2nd junction terminals 6a-6c. There is an effect that it becomes easy to make the arrangement relationship constant.

  Next, a connector 100 according to a second embodiment of the present invention will be described with reference to FIG.

   As shown in FIG. 9, the connector 100 according to the present embodiment includes a plurality of first connecting terminals 4 a to 4 c and a plurality of second connecting terminals 9 as compared with the connector 1 according to the first example described above. The point which does not penetrate each contact which concerns on the junction terminals 6a-6c, and several insulation member 8a-8d differs. That is, in the present embodiment, the connection member 9 is configured only by the head 9a as the pressing portion.

  In the connector 1 according to the first embodiment, the screw member 18 formed on the shaft portion 9b is screwed into the screw hole 19 of the first housing 5 to tighten the connection member 9 to the first housing 5. In the connector 100 according to the present embodiment, since the connecting member 9 is composed only of the head portion 9a, a screw portion 43 as a male screw is formed on the outer periphery of the head portion 9a so as to avoid the packing 14, and the first housing 5 The internal thread 44 which the screw part 43 is screwed into the inner periphery of the connection member insertion hole 26 is cut, and the connection member 9 is fastened to the first housing 5 by screwing the screw part 43 into the female screw 44. did.

  As shown in FIG. 9, the head portion 9a has a shape having two outer meridian dimensions: a large-diameter portion where the packing 14 is provided and a small-diameter portion where a screw portion 43 as a male screw is formed. The connecting member insertion hole 26 has a shape that matches the shape having the two outer dimensions. By configuring in this way, that is, when the head portion 9a is fastened to the connection member insertion hole 26, the screw portion 43 is not disposed in the portion facing the packing 14, and thus an effective waterproof structure can be realized. .

  Further, an elastic member holding portion 45 for engaging and holding the elastic member 15 is formed on the lower surface side (the side facing the first insulating member 8a) of the head portion 9a of the connecting member 9, and this elastic member The elastic member 15 is held by the holding portion 45 and becomes a part of the connection member 9.

  When the first connecting terminals 4a to 4c and the second connecting terminals 6a to 6c are connected using the connector 100, the same procedure as that of the connector according to the first embodiment is performed. That is, after fitting the first connector portion 2 and the second connector portion 3, the screw portion 43 of the connecting member 9 is fastened to the female screw 44 of the first housing 5, and the pressing force by the elastic member 15 is accordingly accompanied. Are sequentially applied to the insulating members 8a to 8d, and the first connecting terminals 4a to 4c and the second connecting terminals 6a to 6c are connected by pressing the insulating members 8a to 8d so as to sandwich the contacts. Thereby, the 1st junction terminals 4a-4c and the 2nd junction terminals 6a-6c can be firmly fixed.

  In the present embodiment, the second joint terminals 6a are not penetrated through the respective contacts and the plurality of insulating members 8a to 8d according to the plurality of first joint terminals 4a to 4c and the plurality of second joint terminals 6a to 6c. It is not necessary to form the contact shapes of ˜6c into shapes that dodge the connection member 9 (for example, the U-shape described above).

  Although the connector 100 according to the second embodiment has been described above, as one of the features of the connector 100 according to the second embodiment, a plurality of connection members 9 are provided, unlike the connector 1 according to the first embodiment described above. It exists in the point which does not penetrate each contact which concerns on the 1st junction terminals 4a-4c and the several 2nd junction terminals 6a-6c, and the some insulation members 8a-8d. Although it can be configured in this way, the plurality of insulating members 8a to 8c are fixed to the other surfaces of the plurality of first joining terminals 4a to 4c, respectively. As a result, the cost of the connecting member 9 can be reduced. Moreover, it leads to the weight reduction of the connection member 9, and it can also contribute to the weight reduction of the whole connector as a result.

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

  In the present embodiment, a three-phase AC power line is assumed. However, according to the technical idea of the present invention, for example, a connector for an automobile, which is a three-phase AC between a motor and an inverter. It is also possible to adopt a configuration in which lines for different uses such as a power line for a power supply and a DC two-phase power line for an air conditioner are connected together. By configuring in this way, it is possible to connect power lines for a plurality of uses at once with a single connector, so there is no need to prepare different connectors for each use, saving space and reducing costs. Can contribute.

  Moreover, in this Embodiment, seeing from the head 9a side of the connection member 9, it is the structure which contacts each of 1st junction terminal 4a-4c and each of 2nd junction terminal 6a-6c linearly. However, each of the first joint terminals 4a to 4c of the first connector part 2 is viewed from the head 9a side of the connection member 9 with respect to each of the second joint terminals 6a to 6c of the second connector part 3. The first housing 5 and the second housing 7 may be configured to intersect at right angles. That is, the first connector portion 2 and the second connector portion 3 may be fitted in an L shape. Similarly, the second housing 7 and the second joint terminals 6a to 6c may be arranged obliquely with respect to the first housing 5 and the first joint terminals 4a to 4c. In this way, by applying the gist of the present invention, the insertion / extraction direction of the second connector portion 3 with respect to the first connector portion 2 can be diversified. In other words, the direction of drawing the cable from the connector can be adjusted to a desired direction, which can contribute to space saving.

  Further, in the present embodiment, the surface of each of the first joint terminals 4a to 4c and the second joint terminals 6a to 6c is roughened by knurling or the like to increase the frictional force and make the terminals difficult to move. You may make it fix firmly in each of a contact.

  Moreover, in this Embodiment, unlike the 2nd junction terminals 6a-6c, although the case where a cable was not connected to the one end side of the 1st junction terminals 4a-4c was demonstrated, it is limited to such a structure. Not. In other words, the connector in the present embodiment can also be used when connecting cables.

  Moreover, in this Embodiment, although the cable excellent in flexibility was used as cable 27a-27c, a rigid cable may be used.

  Moreover, in this Embodiment, although the volt | bolt 12 was demonstrated as an example as the connection member 9, this is not the meaning which limits the structure of the connection member 9 to a volt | bolt shape, For example, the 1st connector part 2 and the 2nd connector A CPA lever (CPA: Connector Position Assurance) shaft portion that fixes the fitting with the portion 3 is configured as a connecting member 9, and the fitting is performed by rotating the CPA lever to fix the connecting member 9 to the head of the connecting member 9. It is good also as a structure which presses toward the front-end | tip of the axial part 9b from the part 9a (or tightens).

  In the present embodiment, the upper surface of the head portion 9a of the bolt 12 as the connecting member 9 is formed with a recess into which a hexagon wrench (also referred to as a hexagonal bar spanner) is fitted. This is based on the assumption that a commercially available hexagon wrench is used. However, assuming that a dedicated tool having a shape not commercially available is used, a concave portion having a shape corresponding to the dedicated tool is used as a bolt as the connecting member 9. It is good also as a structure formed in the upper surface of 12 head parts 9a.

  Further, in the present embodiment, the orientation of the connector in use may be such that the connecting member 9 is in a substantially horizontal state or a substantially vertical state. In other words, the usage condition of the connector in this embodiment does not require the orientation in the usage state.

  In the present embodiment, the adjacent first insulating member 8a is pressed by the head 9a of the connecting member 9 via the elastic member 15 which is a part of the connecting member 9, but the elastic member 15 is interposed therebetween. Instead, the adjacent first insulating member 8a may be pressed directly by the head 9a.
