Connector and connecting unit

1. A connector, comprising:

a connector protrusion to be inserted into a connector socket, the connector protrusion including a locking lever provided on a first surface and a connecting terminal provided on a second surface opposing the first surface or on a front surface; and

a connector frame that surrounds the connector protrusion and has an opening in a surface opposing the first surface of the connector protrusion,

wherein the connector frame is configured such that when the connector frame is moved in a direction opposite to a direction where the connector protrusion is inserted while the connector protrusion is in the connector socket, an end of the locking lever fits into the opening and the locking lever is unlocked.

2. The connector as claimed in claim 1 , wherein

the connector protrusion further includes a first groove formed in a first side surface of the connector protrusion and a second groove formed in a second side surface opposing the first side surface; and

the connector frame further includes a first engaging part configured to engage and slide along the first groove and a second engaging part configured to engage and slide along the second groove.

3. The connector as claimed in claim 2 , wherein a cross section of the connector frame has a U-like shape.

4. A connecting unit, comprising:

a connector protrusion including a locking lever provided on a first surface and a first connecting terminal provided on a second surface opposing the first surface or on a front surface;

a connector socket including a second connecting terminal to be connected with the first connecting terminal and a housing having a groove formed in an inner wall so that the locking lever is pressed down and slides along the groove when the connector protrusion is inserted into the connector socket; and

a connector frame that surrounds the connector protrusion and has an opening in a surface opposing the first surface of the connector protrusion,

wherein the connector frame is configured such that when the connector frame is moved in a direction opposite to a direction where the connector protrusion is inserted while the connector protrusion is in the connector socket, an end of the locking lever fits into the opening and the locking lever is unlocked.

5. A connector, comprising:

a connector protrusion to be inserted into a connector socket, the connector protrusion including a locking lever provided on a first surface and a connecting terminal provided on a second surface opposing the first surface or on a front surface; and

a connector frame that surrounds the connector protrusion,

wherein the connector frame is configured such that when the connector frame is pressed in a direction toward the connector protrusion while the connector protrusion is in the connector socket, an end of the locking lever slides into a space surrounded by the connector frame and the locking lever is unlocked.

6. The connector as claimed in claim 5 , wherein

the connector protrusion further includes a first groove formed in a first side surface of the connector protrusion and a second groove formed in a second side surface opposing the first side surface; and

the connector frame further includes a first engaging part configured to engage and slide along the first groove and a second engaging part configured to engage and slide along the second groove.

7. The connector as claimed in claim 6 , wherein a cross section of the connector frame has a U-like shape.
