First, embodiments of the present disclosure will be listed and described.
The charging connector of the present disclosure includes:
[1] A charging connector mounted on a vehicle, fitted with an external connector of an external power supply device, and used for charging a battery mounted on the vehicle, comprising a housing, and a housing, which is housed in the housing and supplies power to the battery. A pair of power terminals used for power supply, a first relay terminal fixed to one of the pair of power terminals by bolting, and a second relay terminal fixed to the other of the pair of power terminals by bolting. a pair of power lines respectively connected to the first relay terminal and the second relay terminal, and a plurality of signal terminals housed in the housing, When viewed, a region on one side separated by a reference straight line passing through each center axis of the pair of power terminals is a first region, and a region on the other side is a second region, and the plurality of signal terminals When viewed from the direction along the direction, the first relay terminal has an electric wire connection part to which the power line is connected, and is arranged only in the second area of the first area and the second area, and the first relay terminal has a wire connection part to which the power line is connected. The wire connecting portion is located in the first region when viewed from a direction along the fitting direction.

According to this configuration, the power line is connected to the power terminal via the first relay terminal or the second relay terminal. This makes it possible to pull out the power line in a direction intersecting the fitting direction without bending the power line. Therefore, since there is no need to bend the power line, it is possible to downsize the charging connector in the fitting direction. Furthermore, when viewed from the fitting direction, the plurality of signal terminals are arranged only in the second region of the first region and the second region separated by the reference straight line. The wire connecting portion of the first relay terminal is located in the first region when viewed from the fitting direction. This results in a configuration in which the wire connection portion of the first relay terminal and the plurality of signal terminals are not located in the same area. Therefore, there is no need to make the first relay terminal into a complicated shape such as making a detour to avoid the signal terminal. Therefore, it is possible to simplify the structure and downsize the first relay terminal.

[2] In [1] above, the pair of power terminals are arranged in parallel along a first direction perpendicular to the fitting direction, and each of the pair of power lines is arranged along the first direction. They may be pulled out in the same direction.

According to this configuration, when the second direction is a direction perpendicular to each of the fitting direction and the first direction, there is a space for arranging other parts such as an actuator on the side of the charging connector in the second direction. It becomes possible to form.

[3] In [2] above, the first relay terminal includes a terminal fastening part bolted to one of the pair of power terminals, and a connecting part connecting the terminal fastening part and the wire connecting part. The connecting portion may include a first extending portion extending toward the first region, and a second extending portion extending from the first extending portion in a direction in which the power line is pulled out.

According to this configuration, each power line can be drawn out in the same direction along the first direction while being configured so that the first relay terminal and the second relay terminal do not overlap in the fitting direction. Therefore, it is possible to further contribute to miniaturization of the charging connector in the fitting direction.

[4] In the above [3], the terminal fastening portion and the first extending portion have a plate shape perpendicular to the fitting direction, and the second extending portion has a plate shape perpendicular to the fitting direction and the first extending portion. It may have a plate shape that is perpendicular to the second direction that is perpendicular to each of the first directions.

According to this configuration, it is possible to keep the size of the connecting portion of the first relay terminal small in the second direction. Therefore, it is possible to more appropriately form a space for arranging other parts such as an actuator on the side of the charging connector in the second direction.

[5] In any one of [1] to [4] above, each of the pair of power terminals is movable in a direction perpendicular to the fitting direction, and is movable about an axis along the fitting direction. The housing may be rotatably housed in the housing.

According to this configuration, by moving the power terminal relative to the housing, it is possible to absorb vibrations transmitted from the power line. As a result, loosening of the bolts due to vehicle vibration can be suppressed. Further, when the mating terminal of the external connector is inserted into the power terminal, the power terminal can be configured to be movable in the direction orthogonal to the fitting direction in accordance with the position of the mating terminal in the direction orthogonal to the fitting direction. Therefore, even if the position of the mating terminal is deviated due to manufacturing error or the like, it is possible to suppress an increase in the insertion force when connecting the power terminal and the mating terminal to a small level.

[6] In any one of [1] to [5] above, the housing further includes a retainer that holds the position of the signal terminal in the fitting direction, and the housing has an end portion on the side where the external connector is fitted. and a second end, which is an end opposite to the first end, and each of the pair of power terminals and the plurality of signal terminals is connected to the second end. The retainer may be housed in the housing from the opening of the housing, and the retainer may be assembled to the second end, and the retainer may have an abutting portion that abuts the signal terminal in the fitting direction. good. According to this configuration, the position of each signal terminal in the fitting direction can be maintained by the contact portion of the retainer.

[7] In the above [6], the retainer has an opening that exposes the ends of the pair of power terminals to the outside, and the first relay terminal and the second relay terminal are connected to the power supply terminal through the opening. The retainer is bolted to each of the pair of power terminals, and the retainer is provided between a first insulating wall surrounding the first relay terminal and between the first insulating wall and the first relay terminal, and the retainer is provided between the first insulating wall and the first relay terminal, and a first rotation regulating portion that regulates rotation of the relay terminal around a bolt axis; a second insulating wall portion surrounding the second relay terminal; and between the second insulating wall portion and the second relay terminal. A second rotation regulating portion may be provided and regulating rotation of the second relay terminal about the bolt axis.

According to this configuration, it is possible to prevent the first relay terminal from rotating and coming into contact with the first insulating wall portion when tightening or removing the bolt by the first rotation regulating portion. Similarly, the second rotation restricting portion can prevent the second relay terminal from rotating and coming into contact with the second insulating wall portion when tightening or removing the bolt. Therefore, it is possible to suppress the strength required for the first insulating wall portion and the second insulating wall portion.

[8] In any one of [1] to [7] above, each of the pair of power lines may have a size of 40 square meters or more.
According to this configuration, even when using a power line with a large cross-sectional area, there is no need to bend the power line, so it is possible to downsize the charging connector in the fitting direction.

Each first rotation regulating portion 94 is integrally formed on the inner surface of the first insulating wall portion 91 . Further, each first rotation regulating portion 94 is also connected to the outer surface of the main body portion 71 of the retainer 17 .

One of the two first rotation regulating portions 94 regulates rotation of the first relay terminal 21 to one side (eg, clockwise direction) around the bolt axis. The other of the two first rotation regulating portions 94 regulates rotation of the first relay terminal 21 to the other side (eg, counterclockwise direction) around the bolt axis. As a result, the two first rotation regulating portions 94 regulate the rotation of the first relay terminal 21 due to co-rotation both when attaching and removing the bolt B. Note that each first rotation regulating portion 94 is configured to be able to abut on the first extending portion 83a of the first relay terminal 21 in the rotational direction, for example.

The second insulating wall portion 92 surrounds the second relay terminal 22 in the width direction X and thickness direction Z. The second insulating wall portion 92 has an outlet 92a for drawing out the second relay terminal 22 from the inside of the second insulating wall portion 92 to the outside.

The retainer 17 has a second rotation restriction portion 95 between the second relay terminal 22 and the second insulating wall portion 92. In this embodiment, the retainer 17 includes, for example, two second rotation restricting parts 95. Each second rotation regulating portion 95 is integrally formed on the inner surface of the second insulating wall portion 92 . Further, each second rotation regulating portion 95 is also connected to the outer surface of the main body portion 71 of the retainer 17 .

One of the two second rotation restricting portions 95 restricts rotation of the second relay terminal 22 to one side (eg, clockwise direction) around the bolt axis. The other of the two second rotation restricting portions 95 restricts rotation of the second relay terminal 22 to the other side (eg, counterclockwise direction) around the bolt axis. As a result, the two second rotation regulating portions 95 regulate the rotation of the second relay terminal 22 due to co-rotation both when attaching and detaching the bolt B. Note that one of the two second rotation restricting portions 95 is configured to be able to abut against the protruding portion 84a of the second relay terminal 22 in the rotational direction, for example.

The third insulating wall portion 93 surrounds the third relay terminal 23 in the width direction X and the thickness direction Z.

Each third rotation regulating portion 96 is integrally formed on the inner surface of the third insulating wall portion 93 . Further, each third rotation regulating portion 96 is also connected to the outer surface of the main body portion 71 of the retainer 17 .

One of the two third rotation regulating portions 96 regulates rotation of the third relay terminal 23 to one side (eg, clockwise direction) around the bolt axis. The other of the two third rotation restricting portions 96 restricts rotation of the third relay terminal 23 to the other side (eg, counterclockwise direction) around the bolt axis.

Note that each third rotation restricting portion 96 is configured to be able to abut against the protruding portion 86a of the third relay terminal 23 in the rotational direction, for example.

Next, an example of assembling the charging connector 10 will be described.
First, the first power terminal 12 , the second power terminal 13 , and the ground terminal 14 are housed in the housing 11 through the opening of the second end portion 52 .

Next, the position holding member 16 is assembled to the housing 11 from the direction along the thickness direction Z. In this state, the first power terminal 12 and the second power terminal 13 are prevented from coming out in the direction along the insertion/extraction direction Y by the insertion portions 62 of the position holding member 16.

Next, each signal terminal 15 to which the signal line 15a is connected is housed in the housing 11 through the opening of the second end 52.
Next, the retainer 17 is assembled to the housing 11. At this time, the signal line 15a and the lead wire 38a of the temperature sensor 38 are passed through the outlet 77.

Next, the jig P is inserted into each jig hole 37 of the first power terminal 12 through the first opening 56a. Further, a jig P is inserted into each jig hole 37 of the second power terminal 13 through the first opening 56b. Further, the jig P is inserted into each jig hole 47 of the ground terminal 14 through the first opening 56c. By inserting each jig P, rotation of the first power terminal 12, the second power terminal 13, and the ground terminal 14 is restricted.

Next, the first relay terminal 21 is fixed to the second connection portion 32 of the first power terminal 12 with a bolt B. Further, the second relay terminal 22 is fixed to the second connection portion 32 of the second power terminal 13 with a bolt B. Further, the third relay terminal 23 is fixed to the second connection portion 42 of the ground terminal 14 with a bolt B. The rotation of each of the first power terminal 12, the second power terminal 13, and the ground terminal 14 is restricted by the jig P, so that they do not rotate together when the bolts are tightened.

After completing the bolt tightening of the first relay terminal 21, second relay terminal 22, and third relay terminal 23, each jig P is removed. This allows each of the first power terminal 12, the second power terminal 13, and the ground terminal 14 to rotate within a predetermined angular range.

The effects of this embodiment will be explained.
(1) The pair of power lines 24 are connected to the first power terminal 12 and the second power terminal 13 via the first relay terminal 21 and the second relay terminal 22, respectively. Thereby, it becomes possible to pull out the power line 24 in a direction intersecting the fitting direction D (width direction X in this embodiment) without bending the power line 24. Therefore, since there is no need to bend the power line 24, it is possible to downsize the charging connector 10 in the fitting direction D.

Furthermore, when viewed from the insertion/extraction direction Y, the plurality of signal terminals 15 are arranged only in the second area A2 of the first area A1 and the second area A2 separated by the reference straight line L2. The wire connecting portion 82 of the first relay terminal 21 is located in the first area A1 when viewed from the insertion/extraction direction Y. This results in a configuration in which the wire connection portion 82 of the first relay terminal 21 and the plurality of signal terminals 15 are not located in the same area. Therefore, it is no longer necessary to make the first relay terminal 21 into a complicated shape such as to make a detour to avoid the signal terminal 15. Therefore, the structure of the first relay terminal 21 can be simplified and downsized.

(2) The first power terminal 12 and the second power terminal 13 are arranged in parallel along a first direction (width direction X in this embodiment) perpendicular to the fitting direction D. Each of the pair of power lines 24 is drawn out in the same direction along the width direction X as the first direction. According to this configuration, it is possible to form a space above and below the housing 11 in the thickness direction Z in which the actuator 110 and other parts and parts (not shown) are arranged.

(3) The first relay terminal 21 includes a terminal fastening part 81 that is bolted to the first power terminal 12 and a connecting part 83 that connects the terminal fastening part 81 and the wire connecting part 82. The connecting portion 83 has a first extending portion 83a extending toward the first region A1 and a second extending portion 83b extending from the first extending portion 83a in the direction in which the power line 24 is pulled out. According to this configuration, each power line 24 can be pulled out in the same direction along the width direction X while being configured so that the first relay terminal 21 and the second relay terminal 22 do not overlap in the insertion/extraction direction Y. Become. Therefore, it is possible to further contribute to miniaturization of the charging connector 10 in the insertion/extraction direction Y.

(4) The first relay terminal 21 is a press terminal formed from a plate material by press working. The terminal fastening portion 81 and the first extending portion 83a have a plate shape perpendicular to the insertion/extraction direction Y. The second extending portion 83b has a plate shape that is perpendicular to the thickness direction Z that is perpendicular to the insertion/extraction direction Y and the width direction X. According to this configuration, the size of the connecting portion 83 of the first relay terminal 21 in the thickness direction Z can be kept small. Therefore, it is possible to more appropriately form a space above and below the housing 11 in the thickness direction Z in which the actuator 110 and other parts and parts (not shown) are arranged.

(5) Each of the first power terminal 12 and the second power terminal 13 is movable in a direction perpendicular to the mating direction D and rotatable about an axis along the mating direction D. It is housed in a housing 11. According to this configuration, the first power terminal 12 and the second power terminal 13 move relative to the housing 11, thereby making it possible to absorb vibrations transmitted from the power line 24. As a result, loosening of the bolt B due to vehicle vibration can be suppressed. Further, when the mating terminals of the external connector 101 are inserted into the first power terminal 12 and the second power terminal 13, the first power terminal 12 and the second power terminal Power terminal 13 is movable. Therefore, even if the position of the mating terminal of the external connector 101 is shifted due to manufacturing error, the increase in insertion force when connecting the first power terminal 12 and the second power terminal 13 to the mating terminal is minimized. It is possible to suppress it.

(6) The charging connector 10 includes a retainer 17 that holds the position of the signal terminal 15 in the insertion/removal direction Y. The housing 11 has a first end 51 which is an end to which the external connector 101 is fitted, and a second end 52 which is an end opposite to the first end 51. . Each of the first power terminal 12 , the second power terminal 13 , the ground terminal 14 , and the signal terminal 15 is housed in the housing 11 from the opening of the second end 52 . The retainer 17 is assembled to the second end 52. The retainer 17 has a second contact portion 74 against which the ground terminal 14 contacts in the fitting direction D, and a third contact portion 75 against which the signal terminal 15 contacts in the fitting direction D. According to this configuration, the position of the ground terminal 14 in the fitting direction D can be maintained by the second contact portion 74 of the retainer 17. Furthermore, the third contact portion 75 of the retainer 17 makes it possible to maintain the position of the signal terminal 15 in the fitting direction D. Therefore, there is no need to prepare separate parts for holding the position of the ground terminal 14 and parts for holding the position of the signal terminal 15. Therefore, it is possible to suppress an increase in the number of parts of the charging connector 10.

(7) The retainer 17 has an opening 73 that exposes the second connection portion 32 provided at each end of the first power terminal 12 and the second power terminal 13 to the outside. The first relay terminal 21 and the second relay terminal 22 are bolted to the first power terminal 12 and the second power terminal 13, respectively, through the opening 73. The retainer 17 has a first insulating wall portion 91 surrounding the first relay terminal 21 and a first rotation regulating portion 94 provided between the first insulating wall portion 91 and the first relay terminal 21. . The first rotation regulating portion 94 regulates rotation of the first relay terminal 21 about the bolt shaft. According to this configuration, it is possible to prevent the first relay terminal 21 from rotating and coming into contact with the first insulating wall portion 91 when tightening the bolt or removing the bolt B by the first rotation restricting portion 94. Become. Therefore, the strength required for the first insulating wall portion 91 can be kept low.

The retainer 17 also includes a second insulating wall portion 92 surrounding the second relay terminal 22 and a second rotation regulating portion 95 provided between the second insulating wall portion 92 and the second relay terminal 22. ing. The second rotation regulating portion 95 regulates rotation of the second relay terminal 22 about the bolt axis. According to this configuration, the second rotation restricting portion 95 can prevent the second relay terminal 22 from rotating and contacting the second insulating wall portion 92 when tightening the bolt or removing the bolt B. Become. Therefore, the strength required for the second insulating wall portion 92 can be kept low.

(8) The size of each of the pair of power lines 24 is 40 sq or more. A large power line 24 of 40 square meters or more tends to become bulky when bent. Therefore, the effect of miniaturization in the fitting direction D is large when this configuration, which does not require bending the power line 24, is applied.

(9) The charging connector 10 includes a position holding member 16 that holds the position of the first power terminal 12 in the fitting direction D. The housing 11 has a second opening 57a that opens in the thickness direction Z that intersects with the fitting direction D. The position holding member 16 has an insertion portion 62 inserted into the second opening 57a. The insertion portion 62 has a first contact portion 64 against which the first power terminal 12 contacts in the fitting direction D. The insertion portion 62 then comes into contact with the edge of the second opening 57a in the fitting direction D. According to this configuration, when the mating terminal is inserted into the first power terminal 12, the first contact portion 64 of the position holding member 16 receives a load from the first power terminal 12. At this time, the load that the position holding member 16 receives is applied to the contact portion between the insertion portion 62 and the second opening 57a of the housing 11. Therefore, it is possible to improve the strength against insertion of the mating terminal. Further, the same effect can be obtained at the second power terminal 13 as well.
