Abstract

Embodiments of the present disclosure provide a terminal assembly for an electrical device and an electrical device comprising the same. The terminal assembly comprises: a first terminal comprising a terminal seat and a screw in a threaded connection with the terminal seat, a cavity for receiving a wire being formed in the terminal seat; and a second terminal, comprising: a body provided with a hook thereon, wherein the first terminal is adapted to be connected with the second terminal via the hook; and a clamping arm with one end connected with the body and the other end being a free end adapted to cooperate with the body for clamping the wire. Such terminal assembly can provide two different types of terminals to adapt to criteria in different countries and areas, and thus can broaden the application range of the product.

First claim

I claim:

1. A terminal assembly for an electrical device, comprising:
a first terminal comprising a terminal seat and a screw in a threaded connection with the terminal seat, a cavity for receiving a wire being formed in the terminal seat; and
a second terminal, comprising:
a body provided with a hook thereon, wherein the first terminal is adapted to be connected with the second terminal via the hook; and
a clamping arm with one end connected with the body and the other end being a free end adapted to cooperate with the body for clamping the wire.

2. The terminal assembly of claim 1 , wherein the terminal seat of the first terminal comprises a first wall and a second wall opposite to each other, and wherein the first wall is provided with a threaded hole thereon for receiving the screw, and wherein the second wall is adapted to be connected with the second terminal via the hook of the second terminal.

3. The terminal assembly of claim 1 , wherein the body of the second terminal comprises a connection board, with one end of the connection board provided with a first arm and the other end of the connection board provided with a second arm, the first arm and the second arm extending in parallel with each other along a direction perpendicular to the connection board.

4. The terminal assembly of claim 3 , wherein the hook is provided on the first arm.

5. The terminal assembly of claim 4 , wherein a gap for engaging the first terminal is formed between the hook and the first arm.

6. The terminal assembly of claim 3 , wherein the clamping arm is connected with the first arm, and the second arm is provided with a curved portion thereon for cooperating with the clamping arm to clamp the wire.

7. The terminal assembly of claim 3 , wherein the clamping arm is connected with the second arm, and the first arm is provided with a curved portion thereon for cooperating with the clamping arm to clamp the wire.

8. The terminal assembly of claim 3 , wherein the connection board is provided with a recess thereon for allowing the wire to pass through.

9. The terminal assembly of claim 1 , wherein the clamping arm is a resilient arm.

10. The terminal assembly of claim 1 , wherein the clamping arm comprises two clamping arms extending in parallel with each other.

11. The terminal assembly of claim 1 , wherein the second terminal comprises a current-carrying component.

12. An electrical device, comprising a terminal assembly of claim 1 .
