[0005] ,

[0001] Cross-reference to Related Applications This application claims the benefit of Chinese Patent Application No. CN202123416939.0, filed on December 31, 2021, with the China National Intellectual Property Administration, the entire disclosure of which is incorporated herein by reference.

[0002] The present invention relates to a connector and a connector assembly including the connector.

Background Art

[0003] [[ID=1%]] In the prior art, a connector for a lidar generally includes a housing and terminals provided in the housing for transmitting power and signals. The connector is usually directly mounted on a circuit board and electrically connected to the circuit board. However, in some applications, the connector is mounted on a mounting panel instead of a circuit board. At this time, since there is no positioning structure between the connector and the circuit board, the relative position between the connector and the circuit board cannot be guaranteed with high precision, thereby affecting the electrical connection between the terminals of the connector and the circuit board, and in some cases, even causing a failure in the electrical connection.
