A connector is a device for electrically connecting two active devices, the connector being capable of being used to transmit electrical current or signals. For example, connectors can be used in an electric drive system, connected between a connection cable of a motor and a circuit board of a motor controller, as an important communication channel between the motor and the motor controller.

The inventor notices that when the existing connector connects two active devices, if the two active devices have a certain space dislocation, the existing connector is influenced by the structure of the connector, and after the connecting piece of one active device is connected with the connector, the connecting piece of the other active device has a larger turning radius, which is not beneficial to improving the arrangement compactness between the two active devices. For example, in the existing electric drive system, the motor and the motor controller often have a certain space dislocation in relation to each other, that is, the extending direction of the connecting cable of the motor is often not perpendicular to the circuit board of the motor controller, while the connecting terminal of the existing connector and the cavity for accommodating the connecting terminal are often formed to extend along the direction perpendicular to the circuit board so as to be connected with the circuit board of the motor controller, but when the connecting cable of the motor is connected with the connecting terminal of the connector, larger bending is often required, that is, the connecting cable is often required to have a larger turning radius, so that the connecting cable of the motor controller occupies a larger space in the electric drive system, resulting in poor compactness of arrangement between the motor controller and the motor, and thus reducing compactness of the internal structure of the electric drive system.

In order to improve the compactness of the arrangement between the active devices connected by the connector, the applicant has studied to find that the connection terminals of the connector and the cavity of the housing can be divided into sections extending in different directions.

For example, the cavity for accommodating the connection terminal in the housing may be divided into a first cavity and a second cavity extending in different directions, and the connection terminal may be divided into a first section and a second section bent each other.

In such a connector, since the first cavity and the second cavity extend in different directions and the first section and the second section of the connecting terminal are bent and arranged, the first cavity and the second cavity can respectively accommodate and protect the first section and the second section of the connecting terminal, and the first section and the second section can be connected with active devices located in different directions of the connector, so that a connecting piece used for being connected with the connector in the active devices does not need to have a larger turning radius, and the arrangement compactness between the two active devices is improved.

The connector provided by some embodiments of the present utility model may be used to connect active devices such as a motor, a motor controller, etc. to serve as an important communication channel between the active devices. Some embodiments of the utility model are not limited in this regard.
