Abstract

The utility model relates to a transmission structure of a circuit breaker and a shunt release. The circuit breaker mainly solves the problem that the internal structure of a conventional circuit breaker is tedious. The electric tool is characterized by further comprising a first pushing part (111) which is arranged on the first handle; the second pushing part (211) is arranged on the second handle and is opposite to the first pushing part; when the circuit breaker is broken and the first handle rotates, the second pushing part is not on the motion trail of the first pushing part; and when the shunt release is disconnected and the second handle rotates, the second pushing part pushes the first pushing part so as to drive the first handle to rotate. According to the transmission structure of the circuit breaker and the shunt release provided by the utility model, when the shunt release is broken, the circuit breaker is driven, and when the circuit breaker is broken, the shunt release is not driven, so that whether the circuit breaker (triggered) is broken or the shunt release (triggered) is broken can be simply distinguished.

Description

Technical Field

[0001] The utility model relates to the field of low-voltage electrical appliances, in particular to a transmission structure of a circuit breaker and a shunt release. Background Art

[0002] The shunt release is an accessory for remotely controlling the tripping of the circuit breaker. The shunt release is essentially a tripping coil plus a tripper. When the specified voltage is applied to the shunt release coil, the circuit breaker will trip and trip. When used in conjunction with a circuit breaker, the conventional method is to use a linkage rod. In this case, there is a problem that it is difficult to know whether it is the circuit breaker or the shunt release that is disconnected. For this reason, there are shunt releases with indicators on the market, but this will undoubtedly increase the cost of the product and will also occupy additional internal space of the shunt release. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the utility model provides a transmission structure of a circuit breaker and a shunt release, which mainly solves the problem of using indicators and the like to distinguish the disconnection of the shunt release and the circuit breaker, which is costly and requires additional installation space.

[0018] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, a transmission structure of a circuit breaker and a shunt release comprises a circuit breaker housing 1 and a shunt release housing 2, wherein a first tripping mechanism is arranged in the circuit breaker housing, a second tripping mechanism is arranged in the shunt release housing, a first handle 11 rotatably arranged is arranged on the circuit breaker housing, a second handle 21 rotatably arranged is arranged on the shunt release housing, and further comprises a first pushing portion 111 arranged on the first handle; a second pushing portion 211 arranged on the second handle and arranged opposite to the first pushing portion; when the circuit breaker is disconnected and the first handle rotates, the second pushing portion is not on the motion trajectory of the first pushing portion; when the shunt release is disconnected and the second handle rotates, the second pushing portion pushes the first pushing portion and then drives the first handle to rotate.

[0019] When the circuit breaker is disconnected, the first handle rotates, and the first push part does not drive the second push part to rotate, because the second push part is not on the rotation track of the first push part (refer to Figure 2 The arrow in the middle points to the disconnection rotation direction of the handle). In simple terms, the first push part rotates counterclockwise, while the second push part does not drive in the opposite direction; and when the release is disconnected, the second handle moves in the Figure 2The arrow in the figure rotates, and the second push part pushes the first push part at this time; that is to say, when the circuit breaker is disconnected, the two handles are staggered (only the circuit breaker handle is in the disconnected position), and when the separation release is disconnected, the two handles are synchronized (both are in the disconnected position), which can determine which component is tripped without the need for additional components such as indicators.

[0020] In this embodiment, as shown in the figure, the first pushing portion is an L-shaped plate provided on the first handle. As an optional solution, the first pushing portion and the second pushing portion can be symmetrically designed, similar to the upper and lower parts of a square bounded by a diagonal line.

[0021] In this embodiment, as shown in the figure, the first handle is provided with a cross arm 112, and the first pushing portion is provided on the lateral end surface of the cross arm. The second handle is also provided with a cross arm, and the two cross arms are located at the same height.

[0022] In this embodiment, as shown in the figure, the second pushing portion is an L-shaped plate provided on the second handle.

[0023] In this embodiment, as shown in the figure, the first tripping mechanism includes a first lock 31, and the second tripping mechanism includes a second lock 41. The second lock is provided with a tripping pin 411, and part of the tripping pin extends into the circuit breaker housing. The second lock is provided with an open slot 312 arranged opposite to the tripping pin, and the tripping pin is used to push the inner wall of the open slot to rotate and disconnect the first lock when the shunt release is disconnected. When the shunt release is disconnected, the second lock rotates, and the tripping pin also rotates accordingly, and will press against the bottom of the open slot to drive the first lock to rotate in the direction of disconnection to achieve tripping. When the first lock rotates, due to the open slot structure, it will not drive the tripping pin to move.

[0024] In this embodiment, as shown in the figure, the shunt release housing is provided with a hook 23, and the circuit breaker housing is provided with a slot 13 that matches the hook, so as to facilitate the installation between multi-pole housings.
