By the way, in recent years, some electric vehicles such as electric motorcycles and electric bicycles have a battery that can be attached to and detached from the vehicle body. The battery is electrically connected to the inverter, for example, by connecting the second connector provided on the battery to the first connector connected to the inverter provided on the vehicle side. The battery is often attached to and detached from the vehicle body by the user for replacement or charging.

As a connector provided in a connector device for connecting a battery that can be attached to and detached from a vehicle body and an inverter on the vehicle side, two terminals, an anode terminal and a cathode terminal, are arranged side by side in a row as in the conventional case. It is conceivable to use the one that has been used. In this case, when the battery is mounted on the vehicle body, the anode terminal of one connector is connected to the anode terminal of the other connector, and the cathode terminal of one connector is the cathode terminal of the other connector. The battery is inserted into a battery housing portion provided in the vehicle body so as to be connected to the battery. That is, there is only one relative rotational position between the connectors around the axis extending in the connecting direction of the connectors, which enables the connectors to be connected to each other. Therefore, when mounting the battery on the vehicle body, the relative rotational position of the battery and the accommodating portion around the axis extending in the insertion direction of the battery into the accommodating portion should always be set to the same position so that the connectors can be connected to each other. Will be done. However, considering the convenience of the user, it is preferable that there are a plurality of relative rotational positions between the battery and the housing. That is, in the connector device, it is desired that there are a plurality of relative rotational positions of the connectors around the axis extending in the connecting direction of the connectors, which enables the connectors to be connected to each other.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to increase the relative rotational position of the connectors around the axis extending in the connecting direction of the connectors, which enables the connectors to be connected to each other. An object of the present invention is to provide a connector device that can be used.

A connector device for solving the above-mentioned problems includes a first connector having a first reference terminal, a plurality of first terminals, and a first connector-side flow dividing member that short-circuits the plurality of first terminals with each other, and the first reference. A second reference terminal electrically connected to the terminal, and a second terminal electrically connectable to all or some of the first terminals of the first connector and connected to the first connector And a second connector that has the second connector, and the number of the second terminals that the second connector has is less than or equal to the number of the first terminals that the first connector has, and the first connector and the second connector The plurality of first terminals are arranged so as to be rotationally symmetric with respect to the first reference terminal as viewed from the connection direction, and the second terminal has the second reference terminal as the first reference terminal. When facing the connection direction, it is possible to face any of the plurality of first terminals in the connection direction.

According to the above aspect, in the first connector, the plurality of first terminals are arranged so as to be rotationally symmetrical with respect to the first reference terminal as viewed from the connecting direction of the first connector and the second connector. .. Therefore, in a state where the first reference terminal and the second reference terminal are opposed to each other in the connection direction of the first connector and the second connector, the first connector is centered around the second reference terminal around the axis extending in the connection direction. On the other hand, when the second connector is rotated, the second terminal can be connected to the first terminal at a predetermined angle according to the positions of the plurality of first terminals. That is, in the same state, when the second connector is rotated about the second reference terminal about the axis extending in the same connection direction with respect to the first connector, the second connector is rotated at predetermined angles according to the positions of the plurality of first terminals. The second connector can be connected to the first connector. As a result, it is possible to increase the relative rotational position of the first connector and the second connector around the axis extending in the connection direction of the first connector and the second connector, which enables the connection of the first connector and the second connector. ..

The two first terminals of the plurality of first terminals are arranged so as to sandwich the first reference terminal between the two first terminals, and when viewed from the connection direction, the two first terminals are arranged. It is preferable that the first terminal and the first reference terminal are aligned.

According to the above aspect, with the first reference terminal and the second reference terminal facing each other in the connecting direction of the first connector and the second connector, the second reference terminal is centered around the axis extending in the connecting direction. Each time the second connector is rotated by 180° with respect to the first connector, the second terminal can be connected to the first terminal. That is, in the same state, each time the second connector is rotated 180° with respect to the first connector about the second reference terminal about the axis extending in the same connection direction, the second connector can be connected to the first connector. be able to.

The second connector preferably has the same number of the second terminals as the first terminals, and a second connector-side flow dividing member that short-circuits the plurality of second terminals with each other.

According to the above aspect, all the first terminals are energized when the first connector and the second connector are connected. That is, in the same state, there is no first terminal that may be in a non-energized state. Therefore, the current supplied via the first connector-side flow dividing member is always divided into the plurality of first terminals connected to the first connector-side flow dividing member, so that the current is supplied to the first connector-side flow dividing member. The maximum value of the current supplied to each of the plurality of connected first terminals can be suppressed to a small value. As a result, the first terminal connected to the first connector-side flow dividing member can be downsized. Further, the maximum value of the current supplied to each second terminal can be made smaller than in the case where the number of second terminals is smaller than the number of first terminals. As a result, each second terminal can be downsized. For these reasons, the first connector and the second connector can be downsized.

It is preferable that the first connector-side diversion member has a connecting portion to which an electric wire is connected, and that the lengths of current paths from the connecting portion to the plurality of first terminals are equal to each other.

According to the above aspect, in the first connector-side flow dividing member, the electric resistance between the connecting portion and the plurality of first terminals can be made equal to each other. As a result, the current flowing from the connection portion to the first connector-side current dividing member can be equally divided into a plurality of first terminals in the first connector-side current dividing member, so that the magnitude of the current flowing through the first terminal varies or It is possible to suppress a significant difference.

According to the connector device of the present invention, it is possible to increase the relative rotational positions of the connectors around the axis extending in the connecting direction of the connectors, which enables the connectors to be connected to each other.

(1-3) The second connector 22 has the same number of second terminals 132a and 132b as the first terminals 62a and 62b, and the second connector-side flow dividing member 151 that short-circuits the plurality of second terminals 132a and 132b. .. Therefore, when the first connector 21 and the second connector 22 are connected, all the first terminals 62a and 62b are energized. That is, in the same state, there is no first terminal that may be in a non-energized state. Therefore, the current supplied via the first connector-side flow dividing member 81 is always divided into the two first terminals 62a and 62b connected to the first connector-side flow dividing member 81. The maximum value of the current supplied to each of the two first terminals 62a and 62b connected to the connector-side flow dividing member 81 can be suppressed to a small value. As a result, each of the first terminals 62a and 62b connected to the first connector-side flow dividing member 81 can be downsized. In addition, the maximum value of the current supplied to each of the second terminals 132a and 132b can be reduced as compared with the case where the number of the second terminals is smaller than the number of the first terminals 62a and 62b. As a result, each of the second terminals 132a and 132b can be downsized. For these reasons, the first connector 21 and the second connector 22 can be downsized.

(1-4) The first connector-side diversion member 81 has a connecting portion 88 to which an electric wire is connected, and the lengths of current paths from the connecting portion 88 to the first terminals 62a and 62b are equal. Therefore, in the first connector-side flow dividing member 81, the electric resistance between the connecting portion 88 and the first terminals 62a and 62b can be made equal to each other. As a result, the current flowing from the connecting portion 88 to the first connector-side flow dividing member 81 can be equally divided into the first terminals 62a and 62b in the first connector-side flow dividing member 81, so that the first terminals 62a and 62b flow. It is possible to suppress variation or significant difference in the magnitude of current.

Compared to the second connector 22 of the first embodiment, the second connector 22A does not include the second connector-side flow dividing member 151, the bolts 161, 162, and the second terminal 132b. In addition, since the second connector 22A does not include the second terminal 132b, the second housing 100 does not include the insertion hole 121, the positioning recess 122, and the through hole 143 that are provided for the second terminal 132b.

The terminal 132a is inserted into the first terminal 62a and electrically connected.

The second connector 22A shown in FIG. 6C is obtained by rotating the second connector 22A in the state shown in FIG. 6B around an axis extending in the connection direction Z1 about the second reference terminal 131 (that is, the center line L11). It is rotated by 180° around the central axis L12). As shown in FIGS. 6A and 6C, the second connector 22A and the first connector 21 are opposed to each other so that the second reference terminal 131 faces the first reference terminal 61 in the connection direction Z1.

The first terminals 62a to 62d are short-circuited by the first connector-side flow dividing member 81A. An electric wire connected to an inverter (not shown) is electrically connected to the first connector-side flow dividing member 81A.

When the first connector is provided with four or more first terminals, the distance between each of the first terminals and the first reference terminal 61 is such that the plurality of first terminals are the first when viewed from the connection direction Z1. As long as they are arranged so as to be rotationally symmetrical with respect to the one reference terminal 61, they do not necessarily have to be equal.

The same applies to the second embodiment.

In the first embodiment, the first housing 30 is composed of the housing body 31 and the back retainer 32. However, the configuration of the first housing 30 is not limited to this. For example, the first housing 30 may be one in which the housing body 31 and the back retainer 32 are integrally formed. In this case, the first reference terminal 61 and the first terminals 62a, 62b may be insert-molded in the first housing 30 or may be formed as separate parts and assembled.

The same applies to the second embodiment.

In the first embodiment, the shapes of the first housing 30 and the second housing 100 may be changed appropriately. For example, the tubular portion 43 of the first housing 30 may be changed to a tubular shape, an elliptic tubular shape, a polygonal tubular shape, or the like. In this case, the tubular portion 113 of the second housing 100 is also changed according to the shape of the tubular portion 43 of the first housing 30. The same applies to the second embodiment.

-In the said 1st Embodiment, the 1st reference terminal 61 and 1st terminal 62a, 62b with which the 1st connector 21 is equipped are a female terminal, and the 2nd reference terminal 131 and the 2nd terminal with which the 2nd connector 22 is equipped. 132a and 132b are male terminals. However, the first reference terminal 61 and the first terminals 62a and 62b provided in the first connector 21 are male terminals, and the second reference terminal 131 and the second terminals 132a and 132b provided in the second connector 22 are female terminals. May be The same applies to the second embodiment.

In each of the above embodiments, the first reference terminal 61, the first terminals 62a and 62b, the second reference terminal 131, and the second terminals 132a and 132b are all made of copper or a copper alloy, but other than copper and a copper alloy.

For example, the first reference terminal 61, the first terminals 62a and 62b, the second reference terminal 131, and the second terminals 132a and 132b may be made of aluminum or aluminum alloy.

-In each of the above-described embodiments, the shape and configuration of the first reference terminal 61 and the first terminals 62a and 62b may be appropriately changed. In this case, the second reference terminal 131 and the second terminals 132a and 132b are moved by moving the second connector 22 along the center line L11 of the second fitting portion 111, so that the first reference terminal 61 and the first terminal 62a. It suffices to be configured to be detachably electrically connected to the 62b.

For example, the first reference terminal 61 and the first terminals 62a and 62b, which are female terminals, are formed into a cylindrical contact accommodating portion made of a conductive material, and are accommodated inside the contact accommodating portion and electrically connected to the same. The terminal may be composed of a contact member connected to. For example, when the first reference terminal 61 is changed to the terminal, the contact housing is fitted into the central holding portion 52 of the first housing 30, and the inverter is installed outside the first housing 30 in the contact housing. Electrically connect the wires to be connected. The contact member accommodated in the contact accommodating portion is, for example, one having a plurality of leaf springs arranged in the circumferential direction, that is, one having a plurality of leaf springs arranged in a louver shape. .. The contact member is electrically connected to the contact receiving portion by coming into contact with the inner peripheral surface of the contact receiving portion. In this case, when the second reference terminal 131 is inserted into the first reference terminal 61 along the axial direction of the holding portion 52, the terminal body 133 of the second reference terminal 131 is inserted inside the contact member. Then, the plurality of leaf springs of the contact member press the outer peripheral surface of the terminal body 133 inward in the radial direction and contact the outer peripheral surface, whereby the first reference terminal 61 and the second reference terminal 131 are electrically connected to each other. Connected to. With this configuration, each leaf spring of the contact member has a contact portion that comes into contact with the second reference terminal 131, so that the first reference terminal 61 has a large number of contact portions in the circumferential direction. Therefore, the contact resistance between the first reference terminal 61 and the second reference terminal 131 can be reduced, and even when a large current of, for example, 100 A or more is passed through the connector device 20, the contact portion generates heat abnormally. Is suppressed.

Also, as the contact member housed inside the contact housing part, for example, an oblique coil spring can be used. The contact member is electrically connected to the contact receiving portion by coming into contact with the inner peripheral surface of the contact receiving portion. In this case, when the second reference terminal 131 is inserted into the first reference terminal 61 along the axial direction of the holding portion 52, the terminal body 133 of the second reference terminal 131 is inserted inside the contact member. Then, the contact member presses the outer peripheral surface of the terminal body 133 toward the inner side in the radial direction and contacts the outer peripheral surface, whereby the first reference terminal 61 and the second reference terminal 131 are electrically connected. Even in this case, it is possible to obtain the same effect as in the case of using the contact member having the plurality of leaf springs arranged in the louver shape.
