[0034] Example

[0035] The present embodiment provides a control module structure of an electronic molded case circuit breaker, including a controller cover box 1 and an adapter plate 2 arranged below the controller cover box 1, wherein a transformer socket 21 is arranged on the adapter plate 2, and a wire groove 22 for connecting wires on the transformer socket 21 is opened at the controller cover box 1.

[0036] The above specific improvements are: Figure 1 As shown, an adapter plate 2 is arranged below the controller module, and a transformer female socket 21 (i.e., an N-phase plug) is arranged on the adapter plate 2. When a coil needs to be added (i.e., when increasing from level 3 to level 4), it is only necessary to connect a wire from the transformer female socket 21, and then connect the wire from the transformer female socket 21 through a wire groove 22 to the outside to connect the coil. When making a mold for a level 4 transformer shell, it is only necessary to add a part of a shell mold for accommodating the coil on the basis of the original level 3 transformer shell mold. It is also possible to directly use the level 3 transformer shell mold to make the shell, and assemble a coil on the side of the level 3 transformer shell to form a level 4 transformer. No additional mold is required, thereby effectively saving the production cost.

[0037] On the basis of the above embodiment: a sensing module is arranged below the controller cover box 1 , the sensing module comprises a sensing shell 3 , the adapter plate 2 is arranged above the sensing shell 3 , and a buckle structure is arranged between the sensing shell 3 and the controller cover box 1 .

[0039] On the basis of the above embodiment: the snap-on structure includes a main plug-in 4 and an auxiliary plug-in 5 for assisting the main plug-in 4 in plugging in, the main plug-in 4 includes a guide groove 41 arranged on one side of the sensing shell 3 or the controller cover box 1, and a guide strip 42 arranged on the other side and capable of being inserted into the guide groove 41, a snap-on block 43 is arranged on the guide strip 42, and the snap-on block 43 abuts against the end face of the guide groove 41.

[0040] On the basis of the above embodiment: the auxiliary plug-in unit 5 comprises an auxiliary plug-in strip 51 and an auxiliary slot 52 , and an abutment block 53 abutting against the auxiliary plug-in strip 51 is further provided in the controller cover box 1 .

[0041] The above specific improvements are: Figures 2 - 5 As shown, the outside of the guide groove 41 has an extension frame opening downward, and the buckling structure includes a main plug-in 4 and an auxiliary plug-in 5. During the connection process, the guide bar 42 on the main plug-in 4 is aligned with the guide groove 41, and the auxiliary plug-in bar 51 and the auxiliary slot 52 on the auxiliary plug-in 5 will be naturally aligned. When the guide bar 42 is aligned with the guide groove 41, it is inserted downward until the groove on the buckling block 43 conflicts with the extension frame, which means that the controller cover box 1 has been installed in place.

[0042] On the basis of the above embodiment: it also includes a circuit board arranged in the controller cover box 1 , and the circuit board is arranged above the adapter board 2 .

[0043] On the basis of the above embodiment: the induction housing 3 is provided with a wire management groove 6 for inserting the wires of the adapter board 2 and connecting with the transformer module.

[0044] The above specific improvements are: Figure 3 As shown, a circuit board is arranged above the adapter board 2 (the circuit board is a prior art and its structure will not be described in detail here), and the wires on the circuit board will be connected to the adapter board 2, connected by the adapter board 2, and enter the induction housing 3 through the wire management groove 6 to be connected to the transformer module.

[0045] On the basis of the above embodiment: a plug-in unit 8 is provided between the controller cover box 1 and the induction housing 3 to prevent gas from entering the circuit board.

[0046] The above specific improvements are: Figure 4 As shown, the circuit breaker has a contact mechanism. When the contact mechanism is disconnected, airflow will be generated. The airflow will carry metal particles. In order to prevent the metal particles from entering the circuit board, a plug-in 8 for blocking the airflow is provided between the controller cover box 1 and the induction housing 3.

[0047] On the basis of the above embodiment: the lower end surface of the controller cover box 1 is provided with a butt plate 9 which butts against the upper end surface of the induction housing 3 .

[0048] The specific improvements are as follows: Through the provision of the abutting plate 9, when the controller cover box 1 is installed above the induction housing 3 and then pressed downwards, the abutting plate 9 will abut against the upper end face of the induction housing 3 to support the controller cover box 1 and prevent the controller cover box 1 from deforming during the downward pressing process.

[0049] Based on the above embodiment: A middle cover 91 is provided on the circuit breaker, and a trip unit 92 is provided inside the circuit breaker and below the middle cover 91. A positioning post 93 for fixing the trip unit 92 is provided on the middle cover 91, and the trip unit 92 is located above the induction module.

[0050] The specific improvements are as follows: As Figure 6 and Figure 7 shown, after the controller cover box 1 is installed, the middle cover 91 will be covered above the controller cover box 1. To fix the trip unit 92, after the middle cover 91 is covered, the positioning post 93 will abut against the upper end face of the trip unit 92, thereby preventing the trip unit 92 from moving.

[0051] Based on the above embodiment: A demolding hole 94 for facilitating demolding is provided on the induction housing 3, and an extension rib 95 for shielding the demolding hole 94 is provided on the controller cover box 1.

[0052] The specific improvements are as follows: As Figure 8 and Figure 9 shown, to facilitate the manufacture of the induction housing 3, a demolding hole 94 needs to be left on the induction housing 3. However, the existence of the demolding hole 94 causes metal particles generated after the contact mechanism is disconnected to pass through the demolding hole 94, resulting in the adjacent conductive sheets being connected and thus causing a short circuit in the circuit breaker. Therefore, an extension rib 95 for shielding the demolding hole 94 is provided on the controller cover box 1 to increase the airtightness between adjacent conductive sheets.

[0053] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
