Description

  The present invention relates to a connection structure for a vehicle that may be used for a connection portion of a power harness used for an eco-car such as a hybrid vehicle and an electric vehicle, in particular, when transmitting a large amount of power. It is.

  In recent years, significant progress has been made, for example, in hybrid vehicles, electric vehicles, etc., when transferring a large amount of power for connecting devices, such as between a motor and an inverter, or between an inverter and a battery. For example, a power harness used in the above-described configuration includes, on one end thereof, a male terminal and a male side connector portion including a first terminal housing that accommodates the male terminal, a female terminal connected to the male terminal, and the female terminal. A connector having a two-divided configuration with a female connector portion including a second terminal housing to be accommodated is provided (see, for example, 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 connection terminal of a multi-phase conductive member drawn from a motor for driving a vehicle and a connection terminal of a multi-phase power line cable drawn from an inverter that drives the motor. In the electrical connection structure, the connection terminal of each phase of the conductive member and the connection terminal of each phase of the corresponding power line cable are superposed, and the insulating member is disposed on the surface opposite to the superposition surface of the connection terminal This is a technique in which the connection terminals and the insulating members of the respective polymerized phases are fastened and fixed in the polymerization direction by a single bolt provided at a position penetrating them.

  In other words, the technique of Patent Document 2 is to connect a plurality of contact points between connection terminals, which are the overlapping surfaces of connection terminals, by tightening a single bolt in the overlapping direction (laminated structure). Although the connection structure is such that the terminals are fixed to each other and electrically connected to each other, such a configuration is effective in that the size can be easily reduced as compared with the technique disclosed in Patent Document 1.

JP 2009-070754 A Japanese Patent No. 4037199

  Thus, in the vehicle connection structure, vibration countermeasures are indispensable in nature, but when the insulating member and the connecting terminal are provided separately as in Patent Document 2, the insulating member and the connecting terminal are provided. There is a possibility that a slight sliding occurs between the contact point and the contact point, which leads to wear at the contact point.

  Therefore, the present inventors considered to suppress wear at the contact points by fixing the insulating member integrally on the tip end side of the connection terminal and reducing the number of places where the fine sliding is likely to occur as much as possible.

  However, such a configuration has the following problems.

  When the overlapping direction and the gravity direction of the connection structure for a vehicle coincide with each other (it is not necessary to be completely coincident), the tip of the connection terminal to which the insulating member is fixed slightly hangs down due to its own weight that increases as the insulating member is fixed. In such a case, there is a problem in that it is difficult to insert the tip of the connecting terminal to be paired so as to pierce the insulating member at the time of insertion. In addition, even when there is no sag due to its own weight, the same problem occurs when the connecting terminal is deformed so as to be inclined in the tightening direction of the bolt as time passes, such as tightening or loosening the bolt.

  In addition, if the connection terminal is rigidly configured so that the connection terminal to which the insulating member is fixed does not sag, the connection relationship between the connection terminals may be slightly different if the paired connection terminal side is also rigid. However, since it becomes difficult to insert the connection terminals if they are shifted, there is a problem that there is no flexibility when considering the entire connection structure.

  Therefore, in order to cope with such a problem, a configuration in which the insertion side connection terminal is somewhat flexible can be considered. However, with such a configuration, the same problem as described above still occurs.

For example, in a vehicle connection structure in which a plurality of first connection terminals, a plurality of second connection terminals, and a plurality of insulating plates are arranged in a stacked state.

  A preferred embodiment of the present invention will be described first with reference to the accompanying drawings.

  Here, a connector will be described as an example of the connection structure of the present invention.

  FIG. 1 is a perspective view showing a first connector portion and a second connector portion of a connector according to a first embodiment of the present invention, and FIG. 2 is a diagram in which the first connector portion and the second connector portion are fitted together. FIG. 3 is a perspective view showing the connector at the time, and FIG. 3 is a sectional view thereof.

  As shown in FIGS. 1-3, the connector 1 which concerns on this Embodiment is comprised by the 1st connector part 2 and the 2nd connector part 3, and by making these connector parts 2 and 3 fit, a some This is for connecting the power lines together.

  More specifically, the connector 1 includes a first connector portion 2 having a first terminal housing 5 in which a plurality (three) of first connection terminals (male terminals) 4a to 4c are arranged and stored; A second connector portion 3 having a second terminal housing 7 in which three) second connection terminals (female terminals) 6a to 6c are arranged and accommodated; and a plurality of the second connection terminals (female terminals) 6a to 6c arranged in the first terminal housing 5 Insulating plates (insulating members) 8a to 8d, and when the first terminal housing 5 of the first connector part 2 and the second terminal housing 7 of the second connector part 3 are fitted, a plurality of first connection terminals Each of one surface of 4a-4c and each of one surface of the plurality of second connection terminals 6a-6c is a pair (first connection terminal 4a and second connection terminal 6a, first connection terminal 4b and second connection terminal 6b, first 1 connection end 4c and the second connection terminal 6c), and a plurality of insulating plates 8a to 8d are arranged so as to sandwich the pair of first connection terminals 4a to 4c and the second connection terminals 6a to 6c. It will be in the laminated state. That is, when the connector 1 according to the present embodiment is engaged with the first terminal housing 5 of the first connector portion 2 and the second terminal housing 7 of the second connector portion 3, the plurality of first connection terminals 4 a to 4- 4c, a plurality of second connection terminals 6a to 6c, and a plurality of insulating plates 8a to 8d are connectors arranged in a stacked state.

  The connector 1 is used, for example, for connection between a vehicle driving motor and an inverter that drives the motor.

  More specifically, the first terminal housing 5 (the left portion in FIG. 1) of the first connector portion 2 is fitted to the shield case of the motor and is exposed from the first terminal housing 5. The portions of the connection terminals 4a to 4c are connected to the terminals of the terminal block installed in the shield case of the motor. By fitting the second connector portion 3 electrically connected to the inverter to the first connector portion 2, the motor and the inverter are electrically connected. The above is the connection on the motor side, but the same applies to the connection on the inverter side.

  Hereinafter, each structure of the connector parts 2 and 3 is explained in full detail.

  As shown in FIG. 4, the first connector portion 2 holds the three first connection terminals 4 a to 4 c in an aligned state in a state of being spaced apart at a predetermined interval. A first terminal housing 5 in which 4c is arranged and accommodated, a plurality of substantially rectangular parallelepiped insulating plates 8a to 8d provided in the first terminal housing 5 for insulating each of the first connection terminals 4a to 4c, and a head 9b and a shaft portion 9a connected to the head portion 9b. The shaft portion 9a is connected to each of the plurality of first connection terminals 4a to 4c and the plurality of second connection terminals 6a to 6c and the plurality of insulating plates 8a to 8a. The plurality of first connection terminals 4a to 4c and the plurality of second connection terminals 6a to 6c are collectively brought into contact with each other by pressing the adjacent first insulating plate 8a with the head 9b while penetrating 8d. Fixed and electrically To continue, the portion through at least the contact and a connecting member 9 formed of an insulating material.

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

  The first connection 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), Epoxy resin), and is aligned and held at a predetermined interval from a resin molded body 10 which is a part of the first terminal housing 5. As a method of holding the first connection terminals 4a to 4c in the resin molded body 10, for example, a method of inserting the first connection 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 connection terminals 4 a to 4 c are press-fitted and held in a pre-molded resin molded body 10.

  In addition, each of the front end portions (more specifically, the right front end portion in FIG. 4) of the plurality of first connection terminals 4a to 4c is disposed adjacent to the other surface side when in a stacked state. The insulated plates 8a to 8c are integrally fixed so as to protrude further from the tip ends of the first connection terminals 4a to 4c.

  Electricity of different voltage and / or current is transmitted to each of the first connection terminals 4a to 4c. For example, in the present embodiment, a three-phase AC power supply line between the motor and the inverter is assumed, and ACs having 120-phases are transmitted to each of the first connection terminals 4a to 4c. Each of the first connection terminals 4a to 4c 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. In addition, each of the first connection terminals 4a to 4c has some flexibility.

  The plurality of insulating plates 8a to 8d are arranged and housed in the first terminal housing 5 and are opposite to the other surfaces of the plurality of first connection terminals 4a to 4c (the surfaces that are joined to the second connection terminals 6a to 6c). A plurality of first insulating plates 8a to 8c that are integrally fixed to each of the first side housing), and a plurality of first connection terminals 4a to 4c and a plurality of second connections while being housed in the first terminal housing 5. The terminals 6a to 6c are provided so as to face the other surface of the second connection terminal 6c located on the outermost side (the surface opposite to the surface joined to the first connection terminal 4c) when the terminals 6a to 6c are stacked. It consists of a second insulating plate 8d.

  As described above, the plurality of insulating plates 8a to 8c are fixed at positions that protrude toward the distal ends of the first connection terminals 4a to 4c. Each of the insulating plates 8a to 8c is chamfered at each of the corner portions 43 on the front end side where the second connection terminals 6a to 6c are inserted and extracted. More specifically, the insulating plate 8a (or 8b or 8c) fixed to the first connection terminal 4a (or 4b or 4c) has the first connection terminal 4a (or 4b or 4c) to be fixed as the first terminal. When it hangs down from the housing 5, it comes into contact with the second connection terminal 6 a (or 6 b or 6 c) inserted so as to face the first connection terminal 4 a (or 4 b or 4 c) to be fixed, and the first Insulating plates 8a to 8a on the side facing the second connection terminal 6a (or 6b or 6c) to be inserted in order to push up the first connection terminal 4a (or 4b or 4c) to be fixed hanging from the terminal housing 5 A corner 43 on the tip side of 8c is chamfered.

  Further, as shown in FIGS. 5A and 5B, the plurality of first insulating plates 8 a to 8 c are formed with fitting grooves 11 for fitting the first connection terminals 4 a to 4 c to be fixed. The The first connection terminals 4a to 4c to be fixed are fitted into the fitting groove 11 and fixed integrally. Thereby, the step between the first insulating plates 8a to 8c and the first connection terminals 4a to 4c is compensated, and the lower surfaces (lower surfaces in the drawing) of the plurality of first insulating plates 8a to 8c are the first connection terminals 4a to 4c. It becomes the same surface as the lower surface (lower surface in the figure) of 4c. With these configurations, when the first connector portion 2 and the second connector portion 3 are fitted, the tip portions of the first connection terminals 4a to 4c do not come into contact with the tip portions of the second connection terminals to be inserted. There is an effect that insertability in the two connection terminals 6a to 6c is improved. In FIG. 5A, the structure of the first insulating plate 8a is simplified, and the first insulating plates 8a to 8c are drawn in the same manner.

  Referring to FIG. 4 again, the connecting member 9 includes a shaft portion 9a having a surface formed of an insulating material at a portion that penetrates each contact point related to the first connection terminals 4a to 4c and the second connection terminals 6a to 6c. And a head portion 9b that is formed integrally with the shaft portion 9a and serves as a pressing portion that presses the adjacent first insulating plate 8a.

  More specifically, the connecting member 9 is insulative to a metal (for example, SUS, iron, copper alloy, etc.) bolt (cap bolt) 12 and its shaft portion 9a outer periphery (including a portion penetrating each contact). Insulation formed by coating an insulating resin (for example, PPS (polyphenylene sulfide) resin, PPA (polyphthalamide) resin, PA (polyamide) resin, PBT (polybutylene terephthalate), epoxy resin) as a material of Layer 13.

  In addition, as the connection member 9, what formed all with the insulating resin may be used, but the thing which covered the axial part 9a outer periphery of the metal volt | bolt 12 with the insulating layer 13 is used from a viewpoint of intensity | strength. Is preferred. 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.

  On the upper surface (more specifically, the center of the upper surface) of the head portion 9b on the central axis of the connection member 9, an operation tool engagement hole (not shown) that engages a predetermined operation tool is formed. The operation tool engagement hole is for engaging a predetermined operation tool when the connection member 9 such as a hexagonal hole or a driver groove is tightened. In the present embodiment, a cap bolt, specifically a hexagon socket head bolt, is used as the connecting member 9, and therefore the operation tool engagement hole is formed of a hexagon socket.

  A packing 14 is provided on the outer periphery of the head 9 b of the connection member 9 to prevent water from entering the first terminal housing 5. Further, an elastic member 15 that applies a predetermined pressing force to the first insulating plate 8a is provided between the lower surface of the head portion 9b of the connecting member 9 and the upper surface of the first insulating plate 8a immediately below the head portion 9b. The elastic member 15 is composed of a metal (for example, SUS) spring. 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 plate 8a with which the lower part of the elastic member 15 abuts is formed with a concave part 16 that covers (accommodates) the lower part of the elastic member 15, and the bottom part of the concave part 16 (that is, the lower part of the elastic member 15 abuts). A seat member 17 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 plate 8a made of an insulating resin.

  The receiving member 17 disperses the stress applied from the elastic member 15 to the upper surface of the first insulating plate 8a, thereby preventing the first insulating plate 8a from being damaged. Therefore, it is preferable to make the contact area between the receiving member 17 and the first insulating plate 8a as large as possible. In the present embodiment, in order to increase the contact area between the receiving member 17 and the first insulating plate 8a, the receiving member 17 having a shape that contacts the entire bottom surface of the recess 16 is provided.

  The connection member 9 is inserted into the first terminal housing 5 from the surface side (the upper surface side in FIG. 4) of the first connection terminals 4a to 4c to which the first insulating plates 8a to 8c are fixed, and the shaft portion By screwing the screw part 18 formed at the tip of 9a into the screw hole 19 formed in the inner peripheral surface of the first terminal housing 5, the head 9b of the connection member 9 is directed toward the tip of the shaft part 9b. By pressing (from the top to the bottom in FIG. 4), the plurality of first connection terminals 4a to 4c and the plurality of second connection terminals 6a to 6c are fixed together at each contact and electrically connected. I am letting.

  The first terminal 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 to be fitted with the second terminal housing 7 is formed in a tapered shape in consideration of fitting properties with the second connector portion 3. A terminal 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 terminal housing waterproof 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 connection 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, the surface area of the first terminal housing 5 can be increased by forming the flange 24, and heat generated inside the first connector portion 2 (for example, heat generated at each contact) is generated in the first terminal housing 5. When heat is radiated to the outside via the heat dissipation, the 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 regulated by the edge peripheral portion of the lower surface of the head portion 9b 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 terminal housing 5 is formed of an insulating resin, the second insulating plate 8d and the first terminal 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 terminal housing 7 in which a plurality (three) of second connection terminals (female terminals) 6 a to 6 c are arranged and stored. The second terminal housing 7 may be a male (male side terminal housing) or a female (female side terminal housing) as the terminal housing. Here, a case where the second terminal housing 7 is a female terminal housing corresponding to the first terminal housing 5 which is a male terminal housing will be described.

Cables 27a to 27c extending from the inverter side are connected to the respective one ends of the second connection terminals 6a to 6c. Since each of these cables 27a to 27c is electrically connected to each of the first connection terminals 4a to 4c via the second connection terminals 6a to 6c, the voltage corresponding to each of the first connection 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). Each of the second connection terminals 6a to 6c is paired with each of the second connection terminals 6a to 6c when the first connector portion 2 and the second connector portion 3 are fitted by the cable holding member 30. The first connection terminals 4a to 4c facing each other (that is, the connection target) are positioned and held so as to be positioned below each of the first connection terminals 4a to 4c.

  The cable holding member 30 is made of an insulating resin or the like in order to insulate the second connection 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 connection terminals 6a to 6c by the cable holding member 30 is a cable having excellent flexibility, each of the second connection terminals 6a to 6c is predetermined. 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.

  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 connection terminals 6a to 6c. The second connection terminals 6a to 6c are positioned so as to hold the two connection terminals 6a to 6c in a predetermined position, but the cables 27a to 27c are held and the second connection terminals 6a to 6c are also directly held. The positioning of the second connection terminals 6a to 6c may be performed. Further, instead of the cable holding member 30, a connection terminal holding member that directly holds the second connection terminals 6a to 6c without holding the cables 27a to 27c may be used.

  Further, a braided shield 31 is wound around the portions of the cables 27a to 27c drawn from the second terminal 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 terminal housing 5 via the cylindrical shield body 41 (the same potential (GND)). In FIGS. 1 and 2, the braided shield 31 is not shown for simplicity.

  As shown in FIGS. 7 and 8, each of the second connection 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 distal end portion 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 9a 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 connection terminals 6 a to 6 c are separated at the same interval by bending the body portion 35 of the second connection terminal 6 b connected to the cable 27 b arranged 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. In addition, each of the second connection terminals 6a to 6c has some flexibility.

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

  Conversely, the second terminal housing 7 may be fitted into the first terminal housing 5. In this case, the inner peripheral part on one end side of the cylindrical body 20 constituting the first terminal housing 5 is formed in a tapered shape, and the outer peripheral part on one end side of the cylindrical body 36 constituting the second terminal housing 7 is tapered. The terminal 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 hermetic portion 37 is formed on the cable insertion side of the cable holding member 30 to prevent water from entering the second terminal housing 7 through the cables 27a to 27c. A packing 38 that abuts against the inner peripheral surface of the first terminal 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 terminal 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. 1 and 2, the rubber boot 39 is not shown for the sake of simplicity.

  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. The connection member operation hole 40 also serves as a through hole for allowing the connection member 9 to be inserted into and removed from the first terminal housing 5 after the first terminal housing 5 and the second terminal housing 7 are fitted. I also serve. Due to the role as the through hole, the assembly of the connector 1 can be facilitated.

  The cylindrical body 36 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. In the present embodiment, since the cylindrical body 36 is formed of an insulating resin, an aluminum cylindrical shield body is provided on the inner peripheral surface of the other end side of the cylindrical body 36 in order to improve its shielding performance and heat dissipation. 41 is provided.

  The cylindrical shield body 41 has a contact portion 42 that contacts the outer periphery of the first terminal housing 5 made of aluminum when the first connector portion 2 and the second connector portion 3 are fitted together. The first terminal housing 5 is thermally and electrically connected to the first terminal 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 terminal housing 5 side, which is excellent in heat dissipation.

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

  When the first connector portion 2 and the second connector portion 3 are fitted from the non-fitted state shown in FIG. 9, the first connection terminals 4a to 4a are paired with the second connection terminals 6a to 6c. 4c is inserted between each of the insulating plates 8a to 8d. And by this insertion, while facing each one surface of several 1st connection terminals 4a-4c and each one surface of several 2nd connection terminals 6a-6c, it is 1st connection terminal 4a-. 4c, the second connection terminals 6a to 6c, and the insulating plates 8a to 8d are alternately arranged, that is, the first connection terminals 4a to 4c and the second connection terminals 6a to 6c are paired with the insulating plates 8a to 8d. It will be in the lamination state arrange | positioned so that may be pinched | interposed.

  At this time, in the inside of the first connector portion 2, the insulating plates 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 plates 8a to 8c can be maintained without separately providing a holding jig (see Patent Document 2) for holding the interval between the insulating plates 8a to 8c. . Accordingly, each of the second connection terminals 6a to 6c can be easily inserted between each of the pair of first connection terminals 4a to 4c and the insulating plates 8a to 8d. That is, the insertability of the second connection terminals 6a to 6c is not lowered. Further, since it is not necessary to provide a holding jig for holding the interval between the insulating plates 8a to 8c, it is very effective in that further downsizing can be realized as compared with the conventional case.

  Further, the first insulating plate 8a (or the contact point related to the first connection terminal 4a (or 4b) and the second connection terminal 6a (or 6b) is fixed to the first connection terminal 4a (or 4b) constituting the contact point. 8b) and the first insulating plate 8b (or 8c) fixed to the first connection terminal 4b (or 4c) constituting another contact. Similarly, the contact points related to the first connection terminal 4c and the second connection terminal 6c are fixed to the first insulating plate 8c fixed to the first connection terminal 4c constituting the contact and the inner surface of the first terminal housing 5. 2 between the insulating plates 8d.

  Thereafter, as shown in FIG. 3, the operating tool engaging hole of the connecting member 9 is operated from the connecting member operating hole 40 using an operating tool such as a wrench, and the screw portion 18 of the connecting member 9 is moved to the first terminal housing. 5, the connection member 9 is pushed into the bottom of the screw hole 19 while being rotated, and the elastic member 15 causes the first insulating plate 8 a, the first insulating plate 8 b, and the first insulating plate to be pressed. 8c and the second insulating plate 8d are pressed in this order, and the contacts are pressed so as to be sandwiched by any two of the insulating plates 8a to 8d, and the contacts are in contact with each other in an insulated state. At this time, each of the first connection terminals 4a to 4c and each of the second connection terminals 6a to 6c are slightly bent by the pressing from the insulating plates 8a to 8d and are in contact with each other over 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.

  By the way, in the connector 1, the 1st insulating plates 8a-8c are integrally fixed to the front end side of the 1st connection terminals 4a-4c. Therefore, when the connector 1 is used in a state in which the stacking direction (overlapping direction) and the gravitational direction coincide (in FIG. 3, the lower side in the drawing coincides with the lower gravitational direction), as shown in FIG. In addition, the first connection terminals 4a to 4c may be inclined in the direction of gravity (downward) due to the weight of the first insulating plates 8a to 8c. The same applies to the case where the first connection terminals 4a to 4c are deformed to be inclined in the tightening direction, that is, the stacking direction as time passes, such as when the connection member 9 is tightened or loosened.

  In such a case, in the prior art, when the first connector portion 2 and the second connector portion 3 are fitted together, the second connection terminals 6a to 6c abut against the insulating plates 8a to 8c, so that the second connection is smoothly performed. There is a possibility that the terminals 6a to 6c cannot be inserted.

  On the other hand, in the connector 1 according to the present embodiment, since the corners 43 of the first insulating plates 8a to 8c are chamfered, as shown in FIG. At the time of fitting with the connector portion 3, the second connection terminals 6 a to 6 c come into contact with the chamfered corner portion 43, and the first insulating plates 8 a to 8 c are pushed up with respect to the first terminal housing 5. Since the first connecting terminals 4a to 4c are fixed to the first insulating plates 8a to 8c, the first connecting terminals 4a to 4c are also moved to the first terminal housing 5 as the first insulating plates 8a to 8c are pushed up. Pushed up against. If the 1st connector part 2 and the 2nd connector part 3 are made to fully fit in this state, as shown in FIG.10 (c), the 1st connection terminals 4a-4c and the 2nd connection terminals 6a-6c will face each other. To be inserted.

  Thus, according to the connector 1 according to the present embodiment, the first insulating plate 8a (or 8b or 8c) has the first connection terminal 4a (or 4b or 4c) to be fixed attached to the first terminal housing 5. When it hangs down, it contacts the second connection terminal 6a (or 6b or 6c) inserted so as to face the first connection terminal 4a (or 4b or 4c). In order to push up the hanging first connection terminal 4a (or 4b or 4c), the corner 43 on the tip side of the first insulating plates 8a to 8c on the side facing the second connection terminal 6a (or 6b or 6c) is chamfered. For example, even if the first connection terminal 4a (or 4b or 4c) hangs down with respect to the first terminal housing 5, the pair of second connection terminals 6a (or 6b or 6c) can be easily inserted smoothly.

  In the present embodiment, the first connection terminal that hangs down from the first terminal housing 5 by the second connection terminals 6a to 6c by chamfering the corners 43 on the front end side of the first insulating plates 8a to 8c. Although it was set as the structure which pushes up 4a-4c, for example, as shown to Fig.11 (a)-(c), one surface (surface joined with 1st connection terminal 4a-4c) of 2nd connection terminal 6a-6c ) In the fitting direction, and the first connecting terminals 4 a to 4 c may be pushed up by the chamfered portion 44.

  In the present embodiment, the first connection terminals 4a to 4c are assumed to hang depending on the weight of the first insulating plates 8a to 8c, but the first connection terminals 4a to 4c are opposite to the present configuration. The technical idea of the present invention can also be applied to a configuration in which the 4c is firmly aligned and fixed, and the second connection terminals 6a to 6c are aligned and held on the cable holding member 30 with a certain degree of flexibility. That is, the technique of the present invention is also applicable to a configuration in which the cable holding member 30 holds a position far from the second connection terminals 6a to 6c of the cables 27a to 27c, and the tip ends of the second connection terminals 6a to 6c have flexibility. Philosophy can be applied.

  In this case, as shown in FIG. 12A, the second connection terminal 6a (or 6b or 6c) disposed adjacent to the insulating plate 8b (or 8c or 8d) when the laminated state is reached is the second. When the second connection terminal 6a (or 6b or 6c) is inserted when the second connection terminal 6a (or 6b or 6c) is inserted, the second connection terminal 6a (or 6b or 6c) is suspended from the second terminal housing 7. ) And the insulating plate 8b on the side facing the second connection terminal 6a (or 6b or 6c) to push up the second connection terminal 6a (or 6b or 6c) depending on the second terminal housing 7 It is good to set it as the structure where the corner | angular part 45 of the front end side of (or 8c or 8d) is chamfered. As a result, as shown in FIGS. 12B and 12C, when the first connector portion 2 and the second connector portion 3 are fitted, the second connection terminal 6a (or 6b or 6c) hanging down is insulated. The plate 8b (or 8c or 8d) comes into contact with the chamfered corner 45 and is pushed up to be connected to the first connection terminal 4a (or 4b or 4c).

  Further, as shown in FIGS. 13A to 13C, the tip of the other surface of the second connection terminals 6a to 6c is chamfered in place of the corner 45 on the tip of the insulating plate (or 8c or 8d). The second connecting terminals 6a to 6c themselves may be pushed up by the chamfered portion 46.

  10 to 13 are diagrams for explaining the technical idea of the present invention. In these drawings, configurations other than the main parts necessary for the explanation are not shown or are simplified.

  As described above, the present invention provides an insulating plate for pushing up the first connection terminals 4a to 4c or the second connection terminals 6a to 6c hanging from the first terminal housing 5 or the second terminal housing 7. It is characterized in that the corners of 8a to 8d and the second connection terminals 6a to 6c are chamfered. That is, the chamfering in the present invention is not for guiding (inducing) the insertion of the connection terminals, but for correcting the sagging and smoothing the insertion of the connection terminals. For this reason, in the present embodiment, the chamfering process is not performed on the corner portion that does not contribute to the pushing-up of the hanging connection terminal. For example, in FIG. 3, the corners on the upper surface (upper surface in the drawing) side of the insulating plates 8a to 8c and the corners of the insulating plate 8d do not contribute to the pushing up of the connection terminals, and therefore chamfering is not performed. Further, the chamfered shape is not particularly limited, and may be any shape that can push up the hanging connection terminal such as C chamfering or R chamfering.

  In the present embodiment, the screw hole 19 is formed at a position where the screw hole 18 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 b 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 9b side.

  Further, for example, in the present embodiment, the screw hole 19 is formed on the first terminal housing 5 side, but the first terminal housing 5 side is not a screw hole 19 but only a through hole. Further, it may be formed on the second terminal housing 7 side. Moreover, the screw hole 19 may be formed over both the 1st terminal housing 5 side and the 2nd terminal housing 7 side.

  Further, in the present embodiment, each of the first connection terminals 4a to 4c and each of the second connection terminals 6a to 6c are in contact with each other on the surface, but the second surface that is a contact side surface. A configuration in which a convex portion is formed on each of the surfaces on the first connection terminals 4a to 4c side which are in contact with the connection terminals 6a to 6c, and the U-shaped contact 33 of the second connection terminals 6a to 6c is fitted into the convex portion. It is also good. By configuring in this way, it is possible to further stabilize the coupling force between each of the first connection terminals 4a to 4c and each of the second connection terminals 6a to 6c. That is, it is particularly effective against vibration in the direction perpendicular to the connection member 9.

  In the present embodiment, the lengths of the branched tip portions 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 9a of the connecting member 9 even from an oblique direction with respect to the cable longitudinal direction.

  Although the connector according to the first embodiment has been described above, as one of the features of the connector according to the first embodiment, unlike the connector according to the second embodiment described later, a plurality of shaft portions 9a of the connecting member 9 are provided. The first connection terminals 4a to 4c and the plurality of second connection terminals 6a to 6c are contacted with each other and the plurality of insulating plates 8a to 8d. 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, 1st connection terminals 4a-4c and 2nd connection terminals 6a-6c There is an effect that it becomes easy to make the arrangement relationship constant.

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

  As shown in FIG. 10, the connector 100 according to the present embodiment includes a plurality of first connection terminals 4 a to 4 c and a plurality of second connections, as compared with the connector according to the first example described above. The point which does not penetrate each contact which concerns on the terminals 6a-6c, and several insulation plate 8a-8d differs. In other words, in the present embodiment, the connection member 9 is composed only of the head portion 9b as the pressing portion.

  In the connector according to the first embodiment, the connection member 9 is fastened to the first terminal housing 5 by screwing the screw portion 18 formed in the shaft portion 9a into the screw hole 19 of the first terminal housing 5. In the connector 100 according to the present embodiment, since the connecting member 9 is composed only of the head portion 9b, a screw portion 47 as a male screw is formed on the outer periphery of the head portion 9b so as to avoid the packing 14, and the first terminal A female screw 48 into which the threaded portion 47 is screwed is cut on the inner periphery of the connecting member insertion hole 26 of the housing 5, and the connecting member 9 is fastened to the first terminal housing 5 by screwing the threaded portion 47 into the female screw 48. Configured to be.

  As shown in FIG. 14, the head portion 9b has a shape having two outer meridian dimensions, a large diameter portion where the packing 14 is provided and a small diameter portion where the male screw 45 is formed. The 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 9b is fastened to the connection member insertion hole 26, the screw portion 47 is not disposed in the portion facing the packing 14, so that an effective waterproof structure can be realized. .

  Further, an elastic member holding portion 49 for engaging and holding the elastic member 15 is formed on the lower surface side (the side facing the first insulating plate 8a) of the head portion 9b of the connecting member 9, and this elastic member The elastic member 15 is held by the holding portion 49 and becomes a part of the connection member 9.

  When the first connection terminals 4a to 4c and the second connection 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 44 of the connecting member 9 is fastened to the female screw 45 of the first terminal housing 5, and accordingly, the elastic member 15 pushes it. The first connecting terminals 4a to 4c and the second connecting terminals 6a to 6c are connected by sequentially applying pressure to the insulating plates 8a to 8d and pressing the insulating plates 8a to 8d so as to sandwich the contacts. Thereby, the 1st connecting terminals 4a-4c and the 2nd connecting terminals 6a-6c can be firmly fixed.

  In the present embodiment, the second connection terminals 6a are not penetrated through the contact points and the plurality of insulating plates 8a to 8d according to the plurality of first connection terminals 4a to 4c and the plurality of second connection 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 according to the second embodiment has been described above, as one of the features of the connector according to the second embodiment, the connecting member 9 includes a plurality of first connections unlike the connector according to the first embodiment described above. It exists in the point which does not penetrate each contact and the some insulating plates 8a-8d which concern on the terminals 4a-4c and the several 2nd connection terminals 6a-6c. This configuration can be achieved because the plurality of insulating plates 8a to 8c are fixed to the other surfaces of the plurality of first connection 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.

  For example, in the present embodiment, a three-phase AC power supply 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.

  Also, the surface of each of the first connection terminals 4a to 4c and the second connection terminals 6a to 6c is roughened by knurling, etc., the frictional force is increased, the terminals are difficult to move, and fixed at each of the contacts. You may make it harden.

  In the present embodiment, each of the first connection terminals 4a to 4c and the second connection terminals 6a to 6c are viewed from the head 9a side of the connection member 9 with the shaft portion 9a of the connection member 9 as an axis. Although it was the structure which makes each contact in a linear form, each of 1st connection terminal 4a-4c of the 1st connector part 2 with respect to each of 2nd connection terminal 6a-6c of the 2nd connector part 3, The male terminal housing 5 and the female terminal housing 7 may be configured so as to intersect and contact at right angles when viewed from the head side of the connecting member 9. That is, the first connector portion 2 and the second connector portion 3 may be fitted in an L shape. Similarly, the female terminal housing 7 and the second connection terminals 6a to 6c are arranged obliquely with respect to the male terminal housing 5 and the first connection terminals 4a to 4c, with the shaft portion 9a of the connection member 9 as an axis. It can also be configured as follows. As described above, by applying the gist of the present invention, the insertion / extraction direction of the second connector part 3 with respect to the first connector part 2 can be diversified. That is, the direction in which the cable is pulled out from the connector can be matched to the shape of the installation location, which can contribute to space saving.

  Moreover, in this Embodiment, unlike the 2nd connection terminals 6a-6c, although the case where a cable was not connected to the one end side of the 1st connection 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.

  In the present embodiment, the predetermined operation tool is assumed to be a commercially available one, but an operation tool dedicated to this connector may be used.

  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 plate 8a is pressed by the head portion 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 plate 8a may be pressed directly by the head 9a.
