[0002] A circuit breaker is a switching device used to disconnect and connect a load circuit, as well as to cut off a faulty circuit to prevent the escalation of an accident, thereby ensuring the safe operation of the load circuit. A 1U circuit breaker typically includes a first circuit (used to control the on / off of the positive pole of the load circuit) and a second circuit (a through circuit for electrically connecting the negative pole of the load circuit). The first circuit includes a handle and an operating mechanism. The handle slides and drives the contact system to close and open through the operating mechanism.

[0003] In order to indicate the opening and closing status of existing circuit breakers, a mechanical indicating mechanism is often provided in the handle; however, relying solely on the mechanical indicating mechanism to indicate the opening and closing status of the circuit breaker is not reliable enough.

[0066] The following embodiments are combined with the accompanying drawings to further illustrate the specific implementation of the switch device of the present invention. The switch device of the present invention is not limited to the description of the following embodiments.

[0067] The utility model discloses a switch device, specifically a circuit breaker. Further, the circuit breaker is a plug-in circuit breaker. Further, the circuit breaker is a 1U circuit breaker.

[0068] like Figure 1-3 , 5, 7-11 are an embodiment of the switch device of the present invention. The switch device of this embodiment is a single-pole switch device, which includes a shell and a first circuit and a second circuit arranged in the shell; the first circuit is a negative circuit, and the first circuit preferably includes a breakpoint (for example, a breakpoint that can be opened and closed, composed of a moving contact and a static contact), that is, the conduction and disconnection of the first circuit can be controlled by controlling the closing and opening of the breakpoint; the second circuit is a positive circuit, and the second circuit is preferably a straight-through circuit. "Straight-through circuit" means that there is no breakpoint (for example, a breakpoint that can be opened and closed, composed of a moving contact and a static contact) in the second circuit, and it always remains in a conductive state. Furthermore, in actual use of the switch device of this embodiment, the two ends of the first circuit are used to connect the negative conductor on the power supply side and the negative conductor on the load side, and the two ends of the second circuit are respectively used to connect the positive conductor on the power supply side and the positive conductor on the load side.

[0069] Furthermore, the length direction, width direction and height direction of the switch device of the present invention are direction d1, direction d2 and direction d3 respectively, and direction d1, direction d2 and direction d3 are perpendicular to each other; the length direction, width direction and height direction of the shell are respectively the same as direction d1, direction d2 and direction d3.

[0070] Further, such as Figure 1-2As shown in Figures 10-11, the housing includes an outer shell 1a, and the first and second circuits are both disposed within the outer shell 1a. The length, width, and height of the outer shell 1a are respectively aligned with directions d1, d2, and d3. Specifically, the outer shell 1a includes a first outer half shell 1-1a and a second outer half shell 1-2a that are relatively assembled along direction d2.

[0071] Further, such as Figure 1-3 , 5, 7-11, the first circuit includes an operating system, a contact system 11b and an arc extinguishing system, the operating system includes a handle 1b and an operating mechanism 7b, the handle 1b is slidably arranged in the housing (specifically, the handle 1b is slidably arranged in the housing 1a) and switches between the handle closing position and the handle opening position by reciprocating sliding, the contact system 11b includes a moving contact 11-1b and a static contact 11-2b used in conjunction with each other, the handle 1b is transmission-connected to the operating mechanism 7b, and the operating mechanism 7b is transmission-connected to the moving contact 11-1b; when the handle 1b slides to the handle closing position, the handle 1b switches between the handle closing position and the handle opening position by reciprocating sliding. The operating mechanism 7b drives the moving contact 11-1b to the closed position, where it closes with the static contact 11-2b, completing the closing operation of the switch device. The operating mechanism 7b and the switch device switch from the open state to the closed state. When the handle 1b slides to the handle-open position, the handle 1b drives the moving contact 11-1b to the disconnected position through the operating mechanism 7b, disconnecting it from the static contact 11-2b. This completes the opening operation of the switch device, and the operating mechanism 7b and the switch device switch from the closed state to the open state. The arc extinguishing system cooperates with the contact system 11b to extinguish the arc generated by the closing and opening of the contact system 11b. The handle 1b is pressed by an external force to slide into the housing 1a and switch to the handle-closed position. The handle 1b is pulled by an external force to slide out of the housing 1a and switch to the handle-open position.

[0072] Further, such as Figure 3 、 5 As shown in Figures 9 and 9, the moving contact 11-1b and the static contact 11-2b are arranged opposite to each other along the direction d2.

[0073] Specifically, the moving contact 11 - 1b includes a moving contact plate 11 - 11b and a moving contact point 11 - 12b. One end of the moving contact plate 11 - 11b is transmission-connected to the operating mechanism 7b and the other end is provided with the moving contact point 11 - 12b.

[0074] Specifically, the static contact 11-2b includes a static contact plate 11-22b and a static contact point 11-21b, the static contact plate 11-22b includes a first static contact plate segment 11-221b, a second static contact plate segment 11-222b and a third static contact plate segment 11-223b that are bent and connected in sequence, the static contact point 11-21b is arranged on the first static contact plate segment 11-221b, the first static contact plate segment 11-221b and the third static contact plate segment 11-223b are arranged opposite to each other along the direction d2 and relative to the second static contact plate segment 11-222b. b is bent toward the same side thereof, that is, the static touch plate 11-22b is a U-shaped structure as a whole, the first section 11-221b of the static touch plate and the third section 11-223b of the static touch plate are respectively connected to the two ends of the second section 11-222b of the static touch plate by bending, the first section 11-221b of the static touch plate and the third section 11-223b of the static touch plate are located on the same side of the second section 11-222b of the static touch plate, and the third section 11-223b of the static touch plate and the static contact point 11-21b are respectively located on both sides of the first section 11-221b of the static touch plate in the direction d2.

[0075] Further, such as Figure 2-3As shown in Figures 5 and 8, the operating mechanism 7b includes a second rotating shaft 7-2b, a rear connecting rod 7-3b, a first rotating shaft structure 7r and a main reset member 7-8b. The second rotating shaft 7-2b is rotatably arranged, and the handle 1b is driven by the second rotating shaft 7-2b to rotate (that is, the handle 1b switches between the handle closing position and the handle opening position by reciprocating sliding to drive the second rotating shaft 7-2b to rotate reciprocally, and the second rotating shaft 7-2b switches between the second rotating shaft closing position and the second rotating shaft opening position). The rotating shaft 7-2b drives the first rotating shaft structure 7r to rotate through the rear connecting rod 7-3b and the first rotating shaft structure 7r (that is, the second rotating shaft 7-2b switches between the second rotating shaft closing position and the second rotating shaft opening position by reciprocating rotation, and the first rotating shaft structure 7r switches between the first rotating shaft structure closing position and the first rotating shaft structure opening position). The first rotating shaft structure 7r includes a third connecting rod 7-5 that is respectively rotatably arranged and snap-fitted. b and the locking component 7-6b, the first rotating shaft structure 7r is connected to the moving contact 11-1b by transmission, and the main reset component 7-8b acts on the first rotating shaft structure 7r to drive the moving contact 11-1b to move toward the disconnected position. That is, the main reset component 7-8b acts on the first rotating shaft structure 7r to drive the moving contact 11-1b to rotate toward the opening position of the first rotating shaft structure 7r. For example, when the handle 1b drives the operating mechanism 7b to perform the opening operation or after the operating mechanism 7b is tripped, the main reset component 7-8b moves to the first rotating shaft structure 7r. Structure 7r applies a force to rotate it toward the opening position of the first rotating shaft structure, thereby driving the moving contact 11-1b to the disconnected position. When the operating mechanism 7b is normally opening and closing (that is, when the second rotating shaft 7-2b is driven by an external force - the external force comes from the handle 1b or the electric reclosing mechanism 8b mentioned later - to rotate and drive the moving contact 11-1b and the static contact 11-2b to close and open via the first rotating shaft structure 7r), the third connecting rod 7-5b and the locking component 7-6b maintain a snap-fit ​​fit. Furthermore, the operating mechanism 7b also includes a front connecting rod 7-1b, through which the handle 1b is connected to the second rotating shaft 7-2b for transmission, thereby driving the second rotating shaft 7-2b to rotate.Furthermore, the first rotating shaft structure 7r also includes a first rotating shaft 7-4b and a lock spring 7-7b that are rotatably arranged. The first rotating shaft structure 7r is rotatably arranged through the first rotating shaft 7-4b, and the third connecting rod 7-5b and the lock component 7-6b are rotatably arranged on the rotating shaft 7-4b respectively. The second rotating shaft 7-2b is transmission-connected to the third connecting rod 7-5b through the rear connecting rod 7-3b, and the first rotating shaft 7-4b is transmission-connected to the moving contact 11-1b. The main reset member 7-8b acts on the first rotating shaft 7-4b to enable the first rotating shaft structure 7r to drive the moving contact. The main reset member 7-8b is a compression spring, one end of which is engaged with the first shaft 7-4b and the other end is engaged with the housing (specifically, the inner shell 2a of the housing). Furthermore, the rotational directions of the second rotational axis 7-2b, the first rotational axis structure 7r, the first rotational axis 7-4b, the third connecting rod 7-5b and the locking component 7-6b are all the same as the direction d3.

[0076] Specifically, the handle 1b includes a handle connecting protrusion 1-5b, which is rotatably connected to one end of the front connecting rod 7-1b, and the other end of the front connecting rod 7-1b is rotatably connected to the third connecting rod 7-5b. The lock spring 7-7b is a torsion spring mounted on the rotating shaft of the lock component 7-6b, and its two spring arms respectively cooperate with the lock component 7-6b and the first rotating shaft 7-4b.

[0077] Furthermore, as shown in 3-6, the operating mechanism 7b also includes a second rotating shaft reset member 7-9b, which acts on the second rotating shaft 7-2b to make it have a rotation tendency to drive the operating mechanism 7b to open the gate, that is, the second rotating shaft reset member 7-9b acts on the second rotating shaft 7-2b to make it have a tendency to rotate toward the second rotating shaft opening position.

[0078] Specifically, the second rotating shaft reset member 7-9b is a torsion spring, which is sleeved on the rotating shaft of the second rotating shaft 7-2b, one spring arm cooperates with the second rotating shaft 7-2b, and the other spring arm is fixedly set (for example, the spring arm cooperates with the shell to achieve a fixed setting). Furthermore, the shell also includes a first shaft column 2-13a and a first spring limiting portion 2-11a and a second spring limiting portion 2-12a arranged around the first shaft column 2-13a. One end of the rotating shaft of the second rotating shaft 7-2b is inserted into the first shaft column 2-13a. The second rotating shaft 7-2b includes a second rotating shaft hole arranged therein and with an open end opposite to the first shaft column 2-13a, and an energy storage matching portion 7-24b arranged on the inner side wall of the second rotating shaft hole. The second rotating shaft reset member 7-9b The spiral body 7-90b, the first spring limiting portion 2-11a and the second spring limiting portion 2-12a are all located in the second rotating shaft hole, one spring arm cooperates with the first spring limiting portion 2-11a and the spring arm is a fixed arm 7-91b, and the other spring arm cooperates with the second spring limiting portion 2-12a and the spring arm is a movable arm 7-92b; when the switch device is closed (that is, when the operating mechanism 7b performs the closing operation), the second rotating shaft 7-2b rotates toward the second rotating shaft closing position (that is, when the second rotating shaft 7-2b rotates toward the second rotating shaft closing position). Figure 4 、 6 In the direction shown, when the second rotating shaft 7-2b rotates counterclockwise) the energy storage matching portion 7-24b drives the movable arm 7-92b to move so that the second rotating shaft reset member 7-9b stores energy, and the second rotating shaft 7-2b finally rotates to the second rotating shaft closing position; when the switching device is opened (that is, when the operating mechanism 7b performs the opening operation), the second rotating shaft reset member 7-9b releases energy and presses the energy storage matching portion 7-24b through the movable arm 7-92b to rotate the second rotating shaft 7-2b to the second rotating shaft opening position (that is, as shown). Figure 4 、 6In the direction shown, the second rotating shaft 7-2b rotates clockwise), and the second rotating shaft 7-2b eventually rotates to the second rotating shaft opening position. Furthermore, when the switching device is opened, the movable arm 7-92b eventually moves to cooperate with the second spring limiting portion 2-12a; when the switching device is in the opening state (that is, the operating mechanism 7b is in the opening state), the second rotating shaft 7-2b is in the second rotating shaft opening position, the movable arm and the second spring limiting portion 2-12a are limited and cooperate, and the energy storage cooperation portion 7-24b and the movable arm 7-92b are only in contact with each other without any force acting on each other or there is a gap between the two, so that the first rotating shaft 7-4b can be installed in place without overcoming the force of the second rotating shaft reset member 7-9b. Furthermore, the second rotating shaft 7-2b also includes an opening positioning portion 7-22b and a closing positioning portion 7-23b, which are arranged around the rotation center of the second rotating shaft 7-2b. The first spring limiting portion 2-11a is located between the opening positioning portion 7-22b and the closing positioning portion 7-23b in the rotation direction of the second rotating shaft 7-2b. When the switching device completes opening (that is, when the second rotating shaft 7-2b is in the opening position of the second rotating shaft), the opening positioning portion 7-22b and the first spring limiting portion 2-11a are limited and cooperated. When the switching device completes closing (that is, when the second rotating shaft 7-2b is in the closing position of the second rotating shaft), the closing positioning portion 7-23b and the first spring limiting portion 2-11a are limited and cooperated. The opening positioning portion 7-22b and the closing positioning portion 7-23b cooperate with the first spring limiting portion 2-11a to reliably and accurately limit the rotation stroke of the second rotating shaft 7-2b, thereby ensuring the reliable and stable operation of the operating mechanism 7b. Furthermore, the opening positioning portion 7-22b and the closing positioning portion 7-23b are both arranged on the inner side wall of the second rotating shaft hole; the first spring limiting portion 2-11a, the second spring limiting portion 2-12a and the first shaft column 2-13a are all arranged on the inner shell 2a of the shell.

[0079] Furthermore, when the operating system is in the open state, the second rotating shaft 7-2b is in the second rotating shaft open position and triggers the first microswitch 1-3p of the circuit board device p to switch to the first operating state. When the operating system switches to the closed state, the second rotating shaft 7-2p rotates toward the second rotating shaft closed position, releasing the first microswitch 1-3p, and the first microswitch 1-3p switches to the second operating state. The switching of the first microswitch 1-3p between the first and second operating states and the output of the signal facilitate remote monitoring of the position of the second rotating shaft 7-2p, thereby realizing remote monitoring of the open and closed states of the switch device of the utility model.

[0080] Specifically, the first microswitch 1-3p is disposed on a radially opposite side of the second rotating shaft 7-2b. The first microswitch 1-3p is disposed on the first circuit board 1-1p of the first circuit board assembly 1p. The second rotating shaft 7-2b includes a trigger finger 7-21b, which rotates synchronously with the second rotating shaft 7-2b to trigger and release the first microswitch 1-3p. The second rotating shaft 7-2b directly engages with the first microswitch 1-3p via the trigger finger 7-21b, ensuring stable and reliable engagement between the second rotating shaft 7-2b and the first microswitch 1-3p. The first microswitch 1-3p includes a first operating rod or a first operating protrusion, and the trigger finger 7-21b presses the first operating rod or the first operating protrusion to switch the first microswitch 1-3p to the first working state, and the trigger finger 7-21b releases the first operating rod or the first operating protrusion to switch the first microswitch 1-3p to the second working state; the trigger finger 7-21b is arranged on one axial end of the second rotating shaft 7-2b and extends radially toward the first shaft column 2-13a.

[0081] like Figure 18-19 As shown, this is an assembly method of the first rotating shaft 7-4b and the moving contact 11-1b:

[0082] One end of the moving contact 11-1b is inserted into the first rotating shaft 7-4b and the moving contact 11-1b is rotated relative to the first rotating shaft 7-4b; the operating system also includes a contact spring 7-10b, which acts on the moving contact 11-1b to limit it with the first rotating shaft 7-4b. When the moving contact 11-1b and the static contact 11-2b are closed, the moving contact 11-1b rotates relative to the first rotating shaft 7-4b to compress the contact spring 7-10b, and the force of the contact spring 7-10b makes the moving contact 11-1b and the static contact 11-2b contact reliably; the first rotating shaft 7-4b includes a first rotating shaft body 7-41b, and the first rotating shaft body 7-41b includes a contact spring installation arranged therein Slot 7-411b, the contact spring mounting slot 7-411b is provided with a mounting slot opening for the contact spring 7-10b to be installed therein, and the mounting slot opening is provided on one axial end of the first rotating shaft 7-4b (specifically, one axial end of the first rotating shaft body 7-41b), and the contact spring 7-10b is provided in the contact spring mounting slot 7-411b and cooperates with the moving contact 11-1b and the first rotating shaft 7-4b respectively; the side wall of the contact spring mounting slot 7-411b is the mounting slot side wall 7-416b, and the mounting slot side wall 7-416b is provided with a moving contact socket 7-415b for the moving contact 11-1b to pass through, and the moving contact 11-1b swings in the moving contact socket 7-415b when it rotates relative to the first rotating shaft 7-4b. The first rotating shaft structure 7r further includes a protective plate 7-11b disposed on the movable contact 11-1b and moving synchronously therewith. The protective plate 7-11b always blocks the movable contact socket 7-415b. That is, the protective plate 7-11b blocks the movable contact socket 7-415b when the movable contact 11-1b is relatively stationary with the first rotating shaft 7-4b, and the protective plate 7-11b also blocks the movable contact socket 7-415b when the movable contact 11-1b rotates relative to the first rotating shaft 7-4b. Furthermore, the shape of the movable contact socket 7-415b is adapted to the movement trajectory of the movable contact 11-1b when it rotates relative to the first rotating shaft 7-4b. The contact spring 7-10b acts on the movable contact 11-1b to limit the engagement with one end of the movable contact socket 7-415b. In order to achieve the assembly of the moving contact 11-1b and the first rotating shaft 7-4b, the size of the moving contact socket 7-415b in the axial direction of the first rotating shaft 7-4b must be sufficient to allow the end of the moving contact 11-1b provided with the moving contact point 11-12b to pass through smoothly.

[0083] The benefits brought by the protective plate 7-11b are: it can effectively prevent or significantly reduce the entry of charged particles into the contact spring mounting groove 7-411b, thereby avoiding or significantly reducing damage to the contact spring 7-10b and other components, and ensuring that the moving contact 11-1b and the static contact 11-2b are reliably closed.

Furthermore, the protective plate 7-11b is an arc-shaped plate, and a protective plate mounting hole 7-111b is provided in its center. The protective plate 7-11b is mounted on the moving contact 11-1b through the anti-slip plate mounting hole 7-111b.

[0087] Furthermore, the center column 7-414b is coaxially arranged with the first rotating shaft 7-4b. Furthermore, the center column 7-414b also serves as the rotating shaft of the first rotating shaft 7-4b and is rotatably connected to the shell; specifically, the center column 7-414b is rotatably arranged on the inner shell 2a.

This end of the movable contact 11-1b is movably arranged in the movable contact movable groove 7-413b. During assembly, the end of the movable contact 11-1b provided with the movable contact point 11-12 passes through the movable contact socket 7-415b, and the movable contact 11-1b is sleeved on the center column 7-414b, so that the free end of the movable contact plate connecting section 11-111b is placed in the movable contact movable groove 7-413b. Furthermore, the movable contact socket 7-415b and the movable contact movable groove 7-413b are arranged at both axial ends of the first rotating shaft 7-4b.
