Connector

The invention discloses a connector. The connector comprises pins, a lower rubber core, and an upper rubber core, the connector also comprises a protection rubber core arranged between the lower rubber core and the upper rubber core and capable of shielding the pins exposed at the upper rubber core, and the protection rubber core sleeves the pins along the axial direction of the pins in a movable manner. According to the connector, the protection rubber core is provided, and when the connector is not in use, the protection rubber core is employed to shield the pins exposed at the upper rubber core so that the damage due to external collision of the pins is prevented; and when the connector is in use, the protection rubber core can move along the axial direction of the pins so that the pins are exposed and the connection of the pins is facilitated. According to the connector, the service lifetime of the connector can be extended.
