  2. Description of the Related Art Conventionally, a housing having a housing space provided therein and a conductive member disposed in the housing space and a part of which is fixed to the housing are provided. A connector that connects between the two is known. In such a connector, when the housing thermally expands due to heat generation due to a thermal environment or energization, the conductive member fixed to the housing is counteracted from the housing due to a difference in linear expansion coefficient between the housing and the conductive member.

JP 2011-165428 A

  By the way, in the connection between an electric equipment and the electric wire of a power supply side, it is requested | required that the common mode noise which generate | occur | produces from the electric equipment side should be reduced. However, for example, when a member containing a coil, a magnetic body, or the like is attached to the connector as described above to reduce the common mode noise propagated from the electric device side, the member containing the coil, the magnetic body, etc. The weight of the connector increases due to its own weight. For this reason, it is required to increase the size of the connector so as to increase the rigidity of the connector so that the weight of the connector does not affect other members.

  The technology disclosed in the present specification has been created in view of the above-described problems, and reduces common mode noise without increasing the size of the connector, and between the connector and the counterpart terminal. The purpose is to ensure connection reliability.

  The technology disclosed in this specification is a housing provided with a housing space therein, and a conductive member that is disposed in the housing space and connects between an electric device and an electric wire, and is provided at one end thereof. Provided on the other end side, connected to the electric device, and connected between the electric wire side connecting portion connected to the electric wire, and provided between the device side terminal portion and the electric wire side connecting portion. And a conductive member having the wire-side connecting portion fixed to the housing.

  In said connector, the coil part of an electroconductive member is made into the coil shape, it has a function as a coil spring, and a coil part can be expanded-contracted along the extension direction. For this reason, even if the housing is thermally expanded, the reaction force received by the conductive member from the housing is absorbed in the coil portion by expanding and contracting in the extending direction of the coil portion. Fine sliding wear between the two can be suppressed. As a result, it is possible to ensure connection reliability between the connector and the counterpart terminal (terminal on the electrical equipment).

  In the above connector, the coil portion of the conductive member has a coil shape, so that it has a function as a solenoid coil for reducing common mode noise, and the common mode noise transmitted from the electrical equipment side to the conductive member is reduced. Reduced at the coil. Furthermore, since the common mode noise is reduced in a part of the conductive member in this way, it is not necessary to separately arrange a member for reducing the common mode noise inside or outside the connector. It can be avoided. As described above, in the above connector, common mode noise can be reduced without increasing the size of the connector, and connection reliability between the connector and the counterpart terminal (terminal on the electrical equipment side) can be ensured. it can.

  In the above connector, a magnetic body disposed inside the coil portion may be provided.

  According to this configuration, since the magnetic material arranged inside the coil portion functions as a ferrite core, common mode noise is reduced by the magnetic material in addition to the coil portion, and the common that is propagated from the electrical equipment side to the conductive member Mode noise can be effectively reduced in the coil section. In addition, since the magnetic body is arranged inside the coil portion already accommodated in the connector, there is no need to provide a space for arranging the magnetic body inside the connector, and the size of the connector is increased. It can be avoided.

  In the above connector, the coil portion is formed by winding a conductive wire in a coil shape, and the cross-section of the wire is such that the axial width of the coil portion is greater than the width in the direction perpendicular to the axial direction. It may be narrow.

  When the width in the axial direction is narrower than the width in the direction perpendicular to the axial direction, the cross-sectional secondary moment is smaller than that in the case where the cross-sectional area is the same and the axial width of the cross section is equal to or greater than the width in the direction perpendicular to the axial direction. That is, the flexibility of the coil portion is increased. For this reason, the effect which suppresses microsliding wear improves compared with the thing where the cross-sectional area is the same and the width of an axial direction is more than the width | variety of the direction perpendicular | vertical to an axial direction.

  In the above connector, the coil portion may have a rectangular cross section.

  If the cross section of the coil part is a quadrangle, the gap between the windings can be reduced as compared with the case where the cross section is the same and the cross section is circular. Thereby, the physique of a coil part can be made small compared with a thing with the same cross-sectional area and a circular cross section.

  In the connector described above, a plurality of the coil portions may be provided between the device-side terminal portion and the wire-side connection portion.

  The cross-sectional secondary moment of one coil part (referred to as coil part A for the sake of convenience) having a large cross-sectional area and the cross-sectional second of two coil parts (referred to as coil part B for convenience) whose cross-sectional area is ½ of the coil part A When compared with the total value of the secondary moments, the total value of the cross-sectional secondary moments of the two coil parts B is smaller than the cross-sectional secondary moment of the coil part A. For this reason, when a plurality of coil portions are provided, the effect of suppressing fine sliding wear is improved as compared with the case where only one coil portion having a large cross-sectional area is used.

  In the above connector, the plurality of coil portions may be coaxially overlapped.

  According to this structure, it can suppress that the physique of a conductive member becomes large, providing a some coil part.

  According to the technology disclosed in this specification, common mode noise can be reduced without increasing the size of the connector, and connection reliability between the connector and the mating terminal can be ensured.

<Embodiment 1>
The first embodiment will be described with reference to FIG. In the present embodiment, a shield connector (an example of a connector) 1 is illustrated for connecting between a terminal on an electric device (not shown) (for example, an inverter mounted on a vehicle of an electric vehicle or a hybrid vehicle) and a power supply side electric wire W1. To do. As shown in FIG. 1, the shield connector 1 is connected to a synthetic resin housing 10, a shield shell 20 covering the housing, a conductive member 30 disposed inside the housing 10, and a terminal of the electric wire W1. The relay terminal 40 etc. which relay between 30 and the electric wire W1 are provided. In the following description, the left side in each drawing is the front of the shield connector 1, and the upper side in each drawing is the upper side of the shield connector 1.

  As shown in FIG. 1, the housing 10 has a substantially L-shaped cross section as a whole, and has one end projecting forward and the other projecting downward. A housing space 12 is provided inside the housing 10. The accommodating space 12 includes an opening 12A that opens forward, a conductive member accommodating portion 12B that accommodates the conductive member 30, and an electric wire accommodating portion 12C that opens downward and accommodates the end of the electric wire W1. ing.

  As shown in FIG. 1, the opening 12A of the storage space 12 has an inner diameter larger than the inner diameter of the conductive member storage portion 12B. The opening 12 </ b> A is floatingly supported in a state where a substantially cylindrical terminal accommodating portion 14 that opens in the front-rear direction is retained forward by a retainer 16. The terminal accommodating part 14 has a cylindrical cylindrical space 14A inside, and is floatingly supported by the opening 12A so that the terminal accommodating part 14 is orthogonal to the connection direction (front-rear direction) with the terminal on the electric device side. It is possible to move. The electric wire W1 is drawn downward from the electric wire accommodating portion 12C of the accommodating space 12. A rubber plug 17 that seals the vicinity of the end of the electric wire W1 and a back retainer 18 that prevents the rubber plug 17 from coming down are disposed at the lower end of the electric wire housing portion 12C.

  The shield shell 20 is made of a conductive metal material and covers the housing 10 as shown in FIG. As shown in FIG. 1, the shield shell 20 is configured by assembling an upper member 22 and a lower member 24 to each other. The shield shell 20 is for reducing radiation noise radiated from the electric wire W1 or the like, and is grounded to the electric equipment side.

  The conductive member 30 is made of a conductive metal material. As shown in FIG. 1, the conductive member 30 is connected via a connection terminal (an example of a device-side connection portion) 32 connected to a terminal on the electric device side and a relay terminal 40. And an L-shaped terminal (an example of a wire-side connecting portion) 34 connected to the electric wire W1, and a coil portion 36 provided between the connecting terminal 32 and the L-shaped terminal 34.

  The connection terminal 32 is a female terminal that is connected to a terminal on the electric device side with the front-rear direction as the connection direction, and is accommodated in the front portion in the cylindrical space 14A of the terminal accommodating portion 14 described above. The connection terminal 32 has a rectangular tube portion 32A having a front side portion having an elastic contact piece that elastically contacts the terminal on the electric equipment side, and a rear portion thereof that is the coil portion 36. The barrel portion 32B is connected to the one end portion by crimping or welding.

  As shown in FIG. 1, the L-shaped terminal 34 has a substantially L-shaped cross section, and one end thereof is connected to the other end of the coil portion 36 by soldering or welding. The other end of the L-shaped terminal 34 is fixed to the housing 10 by being fastened by the bolt B <b> 1 together with the relay terminal 40 while being in contact with the relay terminal 40. The coil unit 36 will be described in detail later.

  As shown in FIG. 1, the relay terminal 40 is arranged in a posture along the vertical direction, and the upper portion thereof is fastened together with the L-shaped terminal 34 by the bolt B <b> 1 and fixed to the housing 10 as described above. A core wire exposed at the end of the electric wire W1 is connected to the lower portion of the relay terminal 40 by crimping, welding, or the like.

  As shown in FIG. 1, a cover 50 is attached to the rear of the housing 10. The cover 50 is for facilitating the work in the manufacturing process of the shield connector 1 and is provided with a rubber ring 52 for sealing the inside of the housing 10 on the outer peripheral surface thereof. In a state where the cover 50 is removed, the fastening portion by the bolt B1 between the L-shaped terminal 34 and the relay terminal 40 faces the outside, so that the worker can easily perform the fastening work of the bolt B1. After completion of the work, the interior of the housing 10 can be protected in a sealed state by attaching the cover 50 to the housing 10.

  Next, the coil part 36 of the conductive member 30 will be described in detail. As shown in FIG. 1, the coil portion 36 has a coil shape and is flexible, and the extending direction thereof is arranged in a posture along the front-rear direction. The coil portion 36 has a front end portion connected to the barrel portion 32 </ b> B of the connection terminal 32 and a rear end portion connected to one end portion of the L-shaped terminal 34. The outer diameter of the wound portion of the coil portion 36 is substantially the same as the outer diameter of the electric wire W1 and is smaller than the inner diameter of the cylindrical space 14A of the terminal accommodating portion 14. The portion is accommodated in the cylindrical space 14A. The coil portion 36 is formed, for example, by forming a copper wire into a coil shape.

  The coil portion 36 has a function as a coil spring by being coiled, and the front side portion is accommodated in the cylindrical space 14A of the terminal accommodating portion 14 along the front-rear direction. It can be expanded and contracted. Here, since the rear end portion of the coil portion 36 is fixed to the housing 10 via the L-shaped terminal 34, when the housing 10 slides relative to the conductive member 30, the coil portion 36 is It expands and contracts from the side.

  Moreover, the coil part 36 has a function as a solenoid coil which reduces a common mode noise by being coiled. For this reason, the common mode noise propagated to the conductive member 30 is reduced when passing through the coil portion 36. The inductance value of the coil portion 36 that functions as a solenoid coil can be determined according to the magnitude of the generated common mode noise, and the inner diameter and winding of the wound portion of the coil portion 36 according to the determined inductance value. The number, the length of the coil portion 36, and the like can be determined. In addition, the winding direction of the coil part 36 may be either right-handed or left-handed.

  The above is the configuration of the shield connector 1 according to the first embodiment, and the operation thereof will be described next. When the housing 10 is thermally expanded in the shield connector 1, the L-shaped terminal 34 of the conductive member 30 fixed to the housing 10 generates a reaction force from the housing 10 due to the difference in linear expansion coefficient between the housing 10 and the conductive member 30. receive. When the L-shaped terminal 34 receives the reaction force from the housing 10, the reaction force is propagated to the coil portion 36 connected to the L-shaped terminal 34 at the rear end portion. When the reaction force is propagated to the coil portion 36, the coil portion 36 expands and contracts in the front-rear direction from the rear end side due to the reaction force, and thereby the reaction force is absorbed. As a result, propagation of the reaction force to the connection terminal 32 connected to the front end portion of the coil portion 36 is suppressed, and the connection terminal 32 is prevented from sliding in the front-rear direction due to the reaction force. The

  Therefore, even when the housing 10 is thermally expanded in a state where the connection terminal 32 of the shield connector 1 is connected to the terminal on the electric device side, the connection terminal 32 slides in the front-rear direction due to the reaction force. And the occurrence of fine sliding wear between the connection terminal 32 and the terminal on the electric device side due to the reaction force is suppressed.

  Further, when common mode noise is generated on the electric device side in a state where the connection terminal 32 of the shield connector 1 is connected to the terminal on the electric device side, the common mode noise is propagated to the coil portion 36 via the connection terminal 32. It is reduced when passing through the coil part 36. For this reason, it is suppressed that common mode noise is propagated to the electric wire W1 via the L-shaped terminal 34 and the relay terminal 40. As described above, in the shield connector 1, the coil portion 36 of the conductive member 30 has a function of suppressing fine sliding wear between the connection terminal 32 and the terminal on the electric device side, and common mode noise generated on the electric device side. It also has a function to reduce.

  As described above, in the shield connector 1 of the present embodiment, the coil portion 36 of the conductive member 30 has a coil shape so that the coil portion 36 functions along the extending direction. It can be stretched. For this reason, even when the housing 10 is thermally expanded, the reaction force received by the conductive member 30 from the housing 10 is absorbed in the coil portion 36 by the coil portion 36 extending and contracting in the extending direction, and thus the conductive member 30. And fine sliding wear between the terminal on the electric device side can be suppressed. As a result, it is possible to ensure connection reliability between the shield connector 1 and the counterpart terminal (terminal on the electrical equipment).

  Furthermore, in the shield connector 1 of the present embodiment, the coil portion 36 of the conductive member 30 has a coil shape, so that it has a function as a solenoid coil that reduces common mode noise. Propagated common mode noise is reduced in the coil section 36. Further, since the common mode noise is reduced in a part of the conductive member 30 in this way, it is not necessary to separately arrange a member for reducing the common mode noise inside or outside the shield connector 1. The enlargement of 1 can be avoided. As described above, in the shielded connector 1 of the present embodiment, the common mode noise is reduced without increasing the size of the shielded connector 1, and between the shielded connector 1 and the counterpart terminal (terminal on the electrical equipment side). Connection reliability can be ensured.

<Embodiment 2>
Next, Embodiment 2 will be described with reference to FIG. The shield connector 101 of the present embodiment is different from that of the first embodiment in that the ferrite connector 170 is provided and the coil portion 136 is black. Since the other configuration is the same as that of the first embodiment, the description of the structure, operation, and effect is omitted. In FIG. 2, the portions obtained by adding the numeral 100 to the reference numerals in FIG. 1 are the same as the portions described in the first embodiment.

  As shown in FIG. 2, the shield connector 101 according to the second embodiment further includes a ferrite core (an example of a magnetic body) 170. The ferrite core 170 has a cylindrical shape, and is disposed inside the coil portion 136 with the column axis direction along the front-rear direction. Further, the ferrite core 170 is arranged over substantially the entire area inside the wound part of the coil part 136, and only the rear end part is bonded to the inside of the coil part 136. For this reason, even if it is the structure by which the ferrite core 170 was arrange | positioned inside the coil part 136 in this way, the coil part 136 has a function as a coil spring, and can be expanded-contracted along the front-back direction. Yes. The ferrite core 170 is a known ferrite material obtained by molding and firing metal oxide powders such as zinc oxide, nickel oxide, manganese oxide, and iron oxide.

  In the present embodiment, since the ferrite core 170 is arranged inside the coil portion 136 in this way, common mode noise is reduced by the ferrite core 170 in addition to the coil portion 136. Therefore, common mode noise propagated from the electric device side to the conductive member 130 can be effectively reduced in the coil portion 136. Furthermore, since the ferrite core 170 is disposed inside the coil portion 136 already accommodated in the shield connector 101, there is no need to provide a space for arranging the ferrite core 170 inside the shield connector 101. An increase in the size of the shield connector 101 can be avoided.

  Further, by providing the ferrite core 170 as described above, the effect of reducing common mode noise is improved. For this reason, it is possible to reduce the inductance value of the coil part 136 while maintaining the same effect of reducing the common mode noise as when the ferrite core 170 is not arranged, that is, the wound part in the coil part 136. The inner diameter and the number of windings, the length of the coil portion 136, and the like can be reduced, and the coil portion 136 can be downsized as a whole. As a result, the shield connector 101 can be downsized.

  In the shield connector 101 of this embodiment, as shown in FIG. 2, a black enamel coating is applied to the surface of the coil portion 136. Thereby, the heat dissipation of the coil part 136 can be improved, ensuring the insulation of the surface of the coil part 136. FIG. Therefore, by making the coil part 136 black, it is possible to reduce the size of the coil part 136 while maintaining the same heat dissipation as when the coil part 136 is not black. Note that the method for making at least a part of the conductive member 130 black in this way is not limited.

<Embodiment 3>
Next, Embodiment 3 will be described with reference to FIGS. The conductive member 230 of the present embodiment is different from that of the first embodiment in that the coil portion 236 has a square cross section. Since the other configuration is the same as that of the first embodiment, the description of the structure, operation, and effect is omitted. In FIG. 3, the parts obtained by adding the numeral 200 to the reference numerals in FIG. 1 are the same as the parts described in the first embodiment.

  When the cross-sectional area of the coil portion is increased, a large current can be passed through the conductive member. However, when the cross-sectional area is increased, the cross-sectional secondary moment is increased. Here, the cross-sectional secondary moment represents the difficulty of deformation with respect to the bending moment, and the larger the cross-sectional secondary moment, the harder it is to deform. For this reason, when the cross-sectional area is increased, the flexibility of the coil portion is reduced, and the effect of suppressing fine sliding wear is reduced.

  As shown in FIG. 3, the coil portion 236 of the present embodiment is obtained by winding a metal material having a square cross section into a coil shape. The metal material is an example of a conductive wire. More specifically, as shown in FIG. 4, in the cross section of the metal material, the axial width H of the coil portion 236 is narrower than the width W in the direction perpendicular to the axial direction.

  In addition, as shown in FIG. 3, the coil portion 236 has a pair of side surfaces facing each other among the four side surfaces substantially perpendicular to the central axis of the coil portion 236, and the other set of side surfaces with respect to the central axis. It is wound in a substantially parallel posture.

  When the width in the axial direction is narrower than the width in the direction perpendicular to the axial direction, the cross-sectional secondary moment is smaller than that in the case where the cross-sectional area is the same and the axial width of the cross section is equal to or greater than the width in the direction perpendicular to the axial direction. That is, the flexibility of the coil part 236 is increased. For this reason, when the cross-sectional area is increased in order to pass a large current through the conductive member 230, if the axial width is narrower than the width in the direction perpendicular to the axial direction, the cross-sectional area is the same and the axial width is the axial direction. It can be suppressed that the effect of suppressing fine sliding wear is reduced as compared with a width greater than the width in the vertical direction. In other words, the effect of suppressing fine sliding wear is improved as compared with the case where the cross-sectional areas are the same and the axial width is equal to or greater than the width in the direction perpendicular to the axial direction.

  In addition, the coil section 236 has a rectangular cross section, and one set of side faces facing each other among the four side faces is substantially perpendicular to the central axis of the coil section 236, and the other set of side faces is relative to the central axis. As shown in FIG. 5, the gap between the windings can be reduced as compared with the case where the windings are wound in a substantially parallel posture as shown in FIG. Thereby, the physique of the coil part 236 can be made small compared with a thing with the same cross-sectional area and a circular cross section.

  Moreover, when the cross section of the coil part 236 is a square, the end of the coil part 236 is better seated than a circular cross section. For this reason, the angle of the L-shaped terminal 234 can be made difficult to shift with respect to the connection terminal 232. The angle here refers to an angle around the axis of the coil portion 236.

<Embodiment 4>
Next, Embodiment 4 will be described with reference to FIG. The conductive member 330 of the present embodiment is different from that of the third embodiment in that a plurality of coil portions 336 are provided. Since other configurations are the same as those of the third embodiment, description of the structure, operation, and effect is omitted. In FIG. 6, the parts obtained by adding numerals 300 to the reference numerals in FIG. 1 are the same as the parts described in the first embodiment.

  When the cross-sectional area of the coil portion is increased, a large current can be passed through the conductive member. However, when the cross-sectional area is increased, the cross-sectional secondary moment is increased. For this reason, the softness | flexibility of a coil part falls and the effect which suppresses fine sliding wear will fall.

  As shown in FIG. 6, the conductive member 330 of this embodiment is provided with two coil portions 336 (336 </ b> A, 336 </ b> B). As shown in FIG. 6, these two coil portions 336 are coaxially overlapped. In addition, enamel coating is applied to the surfaces of these coil portions 336 so that the windings contact each other when compressed and current does not flow from one coil portion 336 to the other coil portion 336. It has been subjected.

  The cross-sectional secondary moment of one coil part (referred to as coil part A for the sake of convenience) having a large cross-sectional area and the cross-sectional second of two coil parts (referred to as coil part B for convenience) whose cross-sectional area is ½ of the coil part A When compared with the total value of the secondary moments, the total value of the cross-sectional secondary moments of the two coil parts B is smaller than the cross-sectional secondary moment of the coil part A. For this reason, when a large current is passed through the conductive member 330, if only two coil parts 336 are provided instead of increasing the cross-sectional area of the coil part 336, only one coil part 336 having a large cross-sectional area is used. Compared with the case, it can suppress that the effect which suppresses fine sliding wear falls. In other words, the effect of suppressing fine sliding wear is improved as compared with the case where only one coil portion having a large cross-sectional area is used.

  Further, when two coil portions 336 are provided, the surface area is increased as compared with the case where only one coil portion having a large cross-sectional area is used, so that heat dissipation is improved.

  When the two coil portions 336 are overlapped on the same axis, a part of the internal space is shared between the two coil portions 336, so that the space can be used more effectively than when the two coil portions 336 are not overlapped. For this reason, it can suppress that the physique of the electrically-conductive member 330 becomes large, providing the two coil parts 336. FIG.
