[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figure 1-7 , an embodiment provided by the present utility model: An auxiliary contact is added to a universal frame circuit breaker, which includes a circuit breaker body 1. A closing and opening mechanism 4 is arranged inside the circuit breaker body 1. An auxiliary contact 2 is installed on one side of the circuit breaker body 1. A mechanism rotating shaft 5 is arranged inside the closing and opening mechanism 4. The mechanism rotating shaft 5 is connected to the auxiliary contact 2. The user triggers the mechanism rotating shaft 5 through a button on the closing and opening mechanism 4, so that the mechanism rotating shaft 5 can rotate, thereby twisting the rotating shaft of the auxiliary contact 2, and closing and disconnecting the internal contacts of the auxiliary contact 2 to complete the on and off output of the auxiliary contacts.
[0026] In this embodiment, a first connecting rod 3 is arranged on the rotating shaft of the auxiliary contact 2. The first connecting rod 3 is connected to the mechanism rotating shaft 5 through a second connecting rod 6. The cooperation between the first connecting rod 3 and the second connecting rod 6 enables the internal contacts of the auxiliary contact 2 to be closed and disconnected when the mechanism rotating shaft 5 rotates.
[0027] In this embodiment, the circuit breaker body 1 is provided with a connection hole. The circuit breaker body 1 is connected to the auxiliary contact 2 through the connection hole. The user can firmly install the auxiliary contact 2 on the circuit breaker body 1 through the connection hole on the circuit breaker body 1 to prevent the auxiliary contact 2 from detaching from the circuit breaker body 1 during use.
[0028] In this embodiment, one end of the mechanism rotating shaft 5 on the closing and opening mechanism 4 penetrates through the side wall of the circuit breaker body 1 and extends to the outside.
[0029] In this embodiment, a limit hole is opened at the top of one side of the second connecting rod 6. The mechanism rotating shaft 5 is connected to the second connecting rod 6 through the limit hole. A threaded hole is arranged at the middle position of one end of the mechanism rotating shaft 5.
[0030] In this embodiment, round holes are opened at the top of one side of the first connecting rod 3 and at the bottom of one side of the second connecting rod 6. The first connecting rod 3 is connected to the second connecting rod 6 through the round holes. The first connecting rod 3 is connected to the second connecting rod 6 through the round holes. During the rotation of the mechanism rotating shaft 5, the second connecting rod 6 can drive the first connecting rod 3 to rotate on the auxiliary contact 2.
[0031] Working principle: The user manipulates the rotation of the mechanism rotating shaft 5 on the closing and opening mechanism 4 through the button on the circuit breaker body 1. The rotation of the mechanism rotating shaft 5 drives the rotation of the second connecting rod 6, thereby driving the rotation of the first connecting rod 3, causing the rotation of the rotating shaft on the auxiliary contact 2, and driving the closing and opening of the internal contacts of the auxiliary contact 2 to complete the on and off outputs of the auxiliary contacts.

Therefore, the embodiments of the present utility model are exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims concerned.
