AI Technical Summary
Existing residual current circuit breakers cannot use a single housing regardless of whether indicator lights are installed, which increases production costs.
Design a universal circuit breaker structure with or without indicator lights, including first and second mounting slots within a housing, a light-transmitting section, and a breakable shield. The light-transmitting section is used for indicator light mounting, and the shield can cover the light-transmitting section to accommodate both usage conditions.
This design achieves universality with or without indicator lights installed using the same housing, reducing production costs and increasing usability.

[0002] The circuit breaker has the characteristics of advanced structure, reliable performance, strong breaking capacity, and small and beautiful appearance. It is used for overload and short-circuit protection of lighting, power distribution lines and equipment in office buildings, residences and similar buildings, and can also be used for infrequent on-off operation and conversion of lines. It is mainly used in various places such as industry, commerce, high-rise and residential buildings.
[0003] The leakage circuit breaker is a kind of circuit breaker, some of the current leakage circuit breakers have indicator lights, and some do not have indicator lights. The shell with indicator light needs to be provided with a light transmission part, and the shell without indicator light does not need to be provided with a light transmission part, so that a shell cannot be used universally, increasing the production cost of enterprises. UTILITY MODEL CONTENTS
[0004] In order to overcome the shortcomings of the background art, the utility model provides a general circuit breaker structure with or without indicator lamp, which mainly solves the problem that a shell cannot be used universally in two cases of installing or not installing indicator lamp of the circuit breaker.
[0005] The technical scheme of the utility model is,
[0006] A general circuit breaker structure with or without indicator lamp, comprising a shell, a tripping mechanism, a contact mechanism and a control circuit board are arranged in the shell, and further comprising
[0007] A first mounting groove is arranged in the shell and used for installing the indicator lamp.
[0008] A second mounting groove is arranged in the shell.
[0009] A light transmission part is arranged on the shell, and the light transmission part is arranged opposite to the first mounting groove.
[0010] A shielding plate is foldably connected with the shell and comprises a first mounting part detachably connected with the second mounting groove and a shielding part covering the light transmission part after being mounted.
[0011] The light transmission part is a thin wall arranged on the shell.
[0012] The shielding part is a boss arranged on the shielding plate.
[0013] The first mounting groove is in clamping and matching connection with the circumferential outer wall of the indicator lamp.
[0014] A supporting plate is further arranged in the shell, and the supporting plate is in contact with the bottom end surface of the indicator lamp.
[0015] The second mounting groove is arranged in the inner wall of the top of the shell.
[0016] The cross section of the second mounting groove is in the shape of a "convex" character.
[0017] The first mounting part is a convex rib arranged on the shielding plate.
[0018] The shielding plate is arranged integrally with the shell.
[0019] The utility model discloses a general circuit breaker structure with or without indicating lamp, when the indicating lamp is needed, normal use, when the indicating lamp is not needed, the shielding plate is removed and installed, and then the light transmission part can be blocked, and two different use conditions are adapted.

[0024] The utility model discloses a general circuit breaker structure with or without indicating lamp, when the indicating lamp is needed, normal use, when the indicating lamp is not needed, the shielding plate is removed and installed, and then the light transmission part can be blocked, and two different use conditions are adapted.
[0025] In the embodiment, as shown in the drawing, the light transmission part is a thin wall arranged on the shell. The structure is relatively simple, and can be integrally manufactured when manufacturing.
[0026] In the embodiment, as shown in the figure, the shielding part is a boss provided on the shielding plate. After installation, the boss can completely cover the first installation slot.
[0027] In the embodiment, as shown in the figure, the first installation slot is in clamping fit with the circumferential outer wall of the indicator lamp. The installation is relatively convenient.
[0028] In the embodiment, as shown in the figure, a supporting plate 6 is further provided in the shell, and the supporting plate is in contact with the bottom end face of the indicator lamp. The installation is relatively stable, and the supporting plate can be arranged on the upper cover. After installation of the upper cover, the bottom of the indicator lamp is limited.
[0029] In the embodiment, as shown in the figure, the second installation slot is provided on the inner wall of the top of the shell.
[0030] In the embodiment, as shown in the figure, the cross section of the second installation slot is in the shape of a "convex" character.
[0031] In the embodiment, as shown in the figure, the first installation part is a convex rib provided on the shielding plate. After the shielding plate is installed, the convex rib falls into the upper groove part in the shape of a "convex" character. After installation, the boss covers the light-transmitting part. The overall structure is simple, and the use is convenient.
[0032] In the embodiment, as shown in the figure, the shielding plate is integrally arranged with the shell. The shielding plate and the shell can be integrally formed by injection molding.
