The invention relates to a connector and a connector assembly by using the connector. The connector comprises a connector shell; the connector shell is provided with a first terminal whose front end is a contact end; the connector shell is also provided with a first adsorption magnet; and a baffle plate is arranged at the front side of the first adsorption magnet on the connector shell. Due to the baffle plate, direct contact between the first adsorption magnet and a second adsorption magnet can be avoided, the problem of collision fragmentation between the first adsorption magnet and the second adsorption magnet can be avoided, and the service life of the magnet is ensured.
