Electrical connector with locking component

1. An electrical connector, applied for a power storage device, the electrical connector comprising:

a socket, comprising a socket case and a socket terminal, the outer surface of the socket case having a fixing groove, and the socket terminal being configured in the socket case;

a plug, matched the socket and configured to connect to the socket, the plug comprising a plug case and a plug terminal, the plug case having a containing space and a locking hole communicated with the containing space, the containing space being configured to contain the socket case of the socket, the wall of the locking hole having a first locking groove and a second locking groove arranged along the direction perpendicular to the axis, and the second locking groove being located on a side adjacent to the first plug terminal, the plug terminal comprising a first plug terminal and a second plug terminal, the first plug terminal having an axis and configured in the containing space, and the second plug terminal being vertically coupled to the first plug terminal; and

a locking component, disposed in the locking hole of the plug case and configured to move in the locking hole, the locking component having a locking structure corresponding to the first locking groove and the second locking groove;

wherein, when the plug is connected to the socket, the socket terminal embeds into the first plug terminal along the axis direction, so that the socket case is located between the plug case and the first plug terminal and the fixing groove is corresponding to the locking hole, then the locking component moves perpendicularly to the axis direction to engage the locking structure in the second locking groove and engages the locking component in the fixing groove of the socket to lock the plug and the socket.

2. The electrical connector of claim 1 , wherein the plug case has a sleeve structure disposed in the containing space and sleeved the first plug terminal, when the plug is connected to the socket, the socket case is located between the plug case and the sleeve structure.

3. The electrical connector of claim 1 , wherein the plug comprises a back cover connected to the plug case and perpendicular to the first plug terminal, the second plug terminal is configured in the back cover.

4. The electrical connector of claim 1 , wherein the first plug terminal and the second plug terminal are integrally formed.

5. The electrical connector of claim 1 , wherein the first plug terminal comprises a protruding structure, and the second plug terminal comprises a hole, the size of the protruding structure is greater than that of the hole, and the protruding structure is riveted to the hole.

6. The electrical connector of claim 1 , wherein the plug comprises a contacting terminal with cylindrical shape, the contacting terminal is configured in the first plug terminal along the axis direction and contacts the first plug terminal, when the socket is connected to the plug, the socket terminal of the socket contacts the contacting terminal to electrically connect to the first plug terminal.

7. The electrical connector of claim 6 , wherein the contacting terminal has two fixed ends and an elastic portion located between the two fixed ends, when the socket is connected to the plug, the elastic portion resists the socket terminal of the socket with an elastic force.

8. The electrical connector of claim 1 , wherein the extending direction of the locking hole and the direction of the axis of the first plug terminal are perpendicular to each other.

9. The electrical connector of claim 1 , wherein the shape of the locking component is corresponding to the shape of the fixing groove of the socket.
