[0032] The present invention is further described below in conjunction with the accompanying drawings: As shown in the figure, the power-taking device for a molded case circuit breaker includes a housing 1, and the housing is detachably connected to a wiring slot 90 of the molded case circuit breaker; the housing is provided with a receiving slot 2 for placing a wiring screw 91 of the molded case circuit breaker and a power-taking mechanism for electrically connecting to the wiring screw 91. The wiring slot mentioned here refers to a mounting slot for mounting wiring screws on a molded case circuit breaker, which generally includes a platform 901 and an upper edge 902, and a through hole is provided on the upper edge for a screwdriver to pass through. The power-taking device is installed in the wiring slot, and can be detachably connected only to the wiring screw, or connected between the platform and the upper edge, between the wiring screw and the upper edge, and so on.

[0033] In the present invention, as shown in the figure, the housing comprises a first housing 11 and a second housing 12 that are movably matched, and an elastic support member 13 is provided between the first housing and the second housing;

[0034] The first shell contacts the inner wall of one side of the wiring slot of the molded case circuit breaker shell; the second shell contacts the other side of the wiring slot of the molded case circuit breaker under the action of the elastic member; the first shell is provided with the power-taking mechanism for electrically connecting to the wiring screw 91 of the molded case circuit breaker. The power-taking mechanism may include a power-taking sheet electrically connected to the wiring screw, and the power is conducted by a wire electrically connected to the power-taking sheet, or the power is directly obtained through the wire. The first shell and the second shell are provided with a separation force by an elastic support member. After being installed in the wiring slot, the first shell and the second shell are respectively pressed against the inner walls on both sides of the wiring slot by the elastic support member to achieve positioning. The inner wall mentioned here can be a boss or even directly pressed against the wiring gasket.

[0035] In the present invention, as shown in the figure, the second housing is sleeved outside the first housing, and the first housing and the second housing are both provided with a fixing portion 100 for fixing one end of the spring. The fixing portion can be a plane or a boss provided in the first housing and the second housing for spring sleeve.

[0036] In the present invention, as shown in the figure, the first housing is provided with a guide groove 111 on the outside, and the inner wall of the second housing is provided with a protrusion 121 that slidably cooperates with the guide groove, which increases the stability during sliding and also plays a guiding role.

[0037] In the present invention, as shown in the figure, a support plate 14 is provided on the first housing, and a hinged pressing plate 15 is provided on the support plate, and a pressing portion 21 is provided on the second housing, and one end of the pressing plate is arranged opposite to the pressing portion. The pressing plate is pressed down, and one end of the pressing plate presses the pressing portion, and the second housing overcomes the force of the spring and descends, so that the power taking device can be conveniently taken out of the wiring slot.

[0038] In the present invention, as shown in the figure, the housing is also provided with a movable locking member 3, which is used to at least partially extend into the receiving groove when subjected to force to reduce the volume of the receiving groove so that the receiving groove and the wiring screw are tightly connected. The locking member can be manually pressed to extend into the receiving groove or increase the volume in the receiving groove. The extension into the receiving groove mentioned here does not limit its initial position to be set outside the receiving groove, and it can also be as described above to increase the volume in the receiving groove. When the housing is installed outside the fastening screw, there is a certain gap. When the locking member increases the volume in the receiving groove, it will press the screw to achieve fixation. When it needs to be removed, just pull out the locking member.

[0039] In the present invention, as shown in the figure, the locking member comprises a housing 31, and the housing is provided with a guide groove 114 which is slidably matched with the housing, so that the locking member can be stably slid and pulled.

[0040] In the present invention, as shown in the figure, the shell is provided with an elastic arm 32, the elastic wall is provided with a barb 33, and the guide groove is provided with a boss 34 that cooperates with the barb to prevent the shell from being pulled out. It can play a role of limiting the stroke when pulling out, and will not easily detach from the shell.

[0041] In the present invention, as shown in the figure, the housing includes a side plate 510 and a deformable pressing plate 511, and the folding mechanism includes a movable buckle 513 provided on the side plate, and the movable buckle is detachably connected to the pressing plate, and the movable buckle is used to fold the receiving groove when connected to the pressing plate. When the housing is installed outside the screw, the pressing plate will protrude, and at this time, the movable buckle acts to press the pressing plate to shrink the placement groove to achieve fixation.

[0042] In the present invention, as shown in the figure, the movable buckle includes a base 131, a rotatable wrench 132 is provided on the base, a fixing seat 101 is provided on the pressure plate, and a connecting frame 133 is also included. The connecting frame is provided with a first pin shaft 1331 and a second pin shaft 1332, the fixing seat is provided with a first groove 1011 adapted to the first pin shaft, and the wrench is provided with a second groove 1321 adapted to the second pin shaft. The wrench rotates to pull the connecting frame, and the connecting frame pulls the fixing seat to deform the pressure plate, which has a simple structure and is easy to use.

[0043] In the present invention, as shown in the figure, the power taking mechanism includes an electrically connected power taking piece 41 and a wire 42, and the power taking piece is used to be electrically connected to the wiring screw of the molded case circuit breaker. The power taking piece can be an elastic spring sheet, and the wire is connected to it, and the power taking piece can directly contact the wiring screw to obtain electricity.

[0044] In the present invention, as shown in the figure, the power taking sheet is also provided with a temperature sensor 43, and the wire includes a signal line connected to the temperature sensor, so that the current temperature can be obtained in real time, which is more convenient to use.

[0045] In the present invention, as shown in the figure, a limiting groove 120 is provided in the housing to limit the power extraction sheet. The power extraction sheet can be limited to prevent shaking, and can be specifically plugged in the width direction.

[0046] In the present invention, as shown in the figure, the housing is provided with a support foot 331, the outer side of the support foot matches the inclined surface of the inner wall of the guide groove. The inner side of the support foot contacts the fastening screw, and when the housing is installed, the support foot will press the locking screw more and more under the action of the inclined surface, making the installation more stable.

[0047] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0048] The embodiments described with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention. The embodiments should not be regarded as limiting the present invention, but any improvements made based on the spirit of the present invention should be within the scope of protection of the present invention.
