Claims

1. An adapter for a molded case circuit breaker for bridging between a back of the circuit breaker and a rail to allow the circuit breaker to be removably mounted to the rail, characterized by, include A first component connected to the back of a circuit breaker includes a plurality of second connecting portions for engaging with a plurality of first connecting portions located on the back of the circuit breaker, a plurality of first positioning claws extending from the back of the first component, a third connecting portion located in the middle of the lateral direction at the lower end portion of the first component, and a first locking tooth located below the third connecting portion. The second component, arranged at the lower end of the first component, includes second positioning claws extending from the back side on both sides of the upper end of the second component, a fourth connecting portion located at the middle of the upper end of the second component and capable of engaging with the third connecting portion of the first component, and a second locking tooth located below the fourth connecting portion; and A spring located between the first and second locking teeth, wherein the spring is used to bias the second locking tooth of the second component away from the first locking tooth to hold the second component relative to the first component in the clamping position of the adapter so that the circuit breaker is held on the guide rail, wherein the spring is designed to move the second locking tooth vertically toward the first locking tooth under the action of an external force so that the second component moves vertically relative to the first component to the open position of the adapter to install or remove the circuit breaker from the guide rail, and after the external force is removed, the spring biases the second locking tooth away from the first locking tooth again and returns to the clamping position of the adapter.

2. The adapter for use with a molded case circuit breaker of claim 1, wherein, The first component further includes a first disassembly hole and a second disassembly hole located at the lower end of the first component. The first disassembly hole and the second disassembly hole are designed as through holes that are generally rounded rectangles.

3. The adapter for use with a molded case circuit breaker of claim 2, wherein, The second component also includes a third and a fourth disassembly hole located at the lower end of the second component. The third and fourth disassembly holes are designed as through holes that are generally rounded rectangles.

4. The adapter for use with a molded case circuit breaker of claim 1, wherein, The ratio of the vertical distance between the plurality of first connecting portions to the horizontal distance between them ranges from 3:1 to 4:

1.

5. The adapter for use with a molded case circuit breaker of claim 1, wherein, The ratio of the distance between the two first positioning claws to the distance between the two second positioning claws is 3:2 to 2:

1.

6. The adapter for use with a molded case circuit breaker of claim 1, wherein, When the adapter is in the clamped position, the fourth connecting part abuts against the third connecting part and the lower ends of the third and fourth disassembly holes overlap with the upper ends of the first and second disassembly holes, respectively. When the adapter is in the open position, the second component moves downward by operating the third or fourth disassembly hole, so that the third and fourth disassembly holes completely overlap with the first and second disassembly holes, respectively.

7. The adapter for use with a molded case circuit breaker of claim 1, wherein, The first component has a plurality of protrusions toward the circuit breaker side, which are used to create a predetermined gap between the first component and the circuit breaker after assembly.

8. The adapter for use with a molded case circuit breaker of claim 1, wherein, The first component has a plurality of vertically extending grooves located below the first positioning claw, with thin plates on both sides of the grooves protruding towards the guide rail side, which together with the first positioning claw clamp the upper part of the guide rail.

9. The adapter for use with a molded case circuit breaker of claim 1, wherein, The first component has multiple protrusions on the guide rail side, with its upper end abutting against the lower edge of the guide rail, and together with the second positioning claw, clamping the lower part of the guide rail.
