However, the intelligent miniature circuit breaker in the prior art is generally larger than the common miniature circuit breaker in size and inconsistent in appearance due to the addition of the intelligent control device, so that the intelligent miniature circuit breaker cannot be directly used, and the basic equipment for placing the miniature circuit breaker is required to be adaptively modified before use, so that the intelligent miniature circuit breaker is large in early investment and long in construction period, and is not beneficial to the intelligent power grid propulsion process.
How to increase the kick speed of the kick assembly of the miniature circuit breaker is important to achieve reduced arcing and safe operation. And how to reduce the structural size as much as possible while guaranteeing the kick speed, reduce the whole appearance size of the intelligent miniature circuit breaker, is the problem that needs to be solved in the present stage.

The kick assembly of the present invention is disposed within a miniature circuit breaker, comprising: the driving connecting piece is connected to the shell of the miniature circuit breaker in a swinging way and comprises a containing groove; a movable contact connecting member connected to the movable contact portion and including a connecting hole; the fixing piece is connected to the shell of the miniature circuit breaker in a swinging mode and swings to switch from a locking position to a kick position. The fixed part is positioned at the locking position when no jump occurs, and the movable contact connecting part is locked in the accommodating groove through a locking piece; when in a jump, the fixing piece is positioned at the jump position, and the locking piece drives the movable contact connecting piece to be separated from the containing groove. Specific examples are described below.
First embodiment
The kick assembly is arranged in the miniature circuit breaker and is used for realizing quick separation of the dynamic contact and the static contact. As shown in fig. 1 to 4, the miniature circuit breaker includes a housing 100, a stationary contact part 300 (refer to fig. 4), a movable contact part 723, and a kick assembly 600. The snap assembly 600 includes a drive connector 610, a movable contact connector 620, a stationary member 630, and a locking member 640. The driving connection member 610 is swingably connected to the housing 100, and includes a receiving groove 611. The movable contact connection 620 is connected to the movable contact portion 723, which includes a connection hole 621. The fixing member 630 is swingably coupled to the housing 100, and has a locking hole 631 and a kick hole 632.
As shown in fig. 2, before the jump, the fixing member 630 is located at the locking position, and the locking member 640 is inserted into the locking hole 631 of the fixing member 630 and the connecting hole 621 of the movable contact connecting member 620, so as to lock the movable contact connecting member 620 in the accommodating groove 611 of the driving connecting member 610, and when the driving connecting member 610 moves, the movable contact connecting member 620 is driven to move, so that the movable contact portion 723 connected with the movable contact connecting member 620 is driven to move.
As shown in fig. 3, when the fixing member 630 is in the snap position, the locking member 640 moves from the locking hole 631 of the fixing member 630 to the snap hole 632, i.e. the locking member 640 is inserted into the snap hole 632 of the fixing member 630 and the connecting hole 621 of the movable contact connecting member 620, and the movable contact connecting member 620 is separated from the receiving groove 611 of the driving connecting member 610.
The locking hole 631 and the snap hole 632 of the fixing member 630 are communication holes, and the locking hole 631 is located at an upper portion of the snap hole 632. And a partition wall S is provided between the locking hole 631 and the kick hole 632, for example, the locking hole 631 and the kick hole 632 are integrally heart-shaped. When the fixing member 630 is rotated clockwise by a certain external force, the locking member 640 is blocked by the sidewall of the receiving groove 611 of the driving link 610, and the locking member 640 moves from the locking hole 631 to the kick hole 632 across the partition wall S.
The drive connection 610 further includes a snap outer wall 612, the snap outer wall 612 being connected to the receiving groove 611. The snap outer wall 612 is arcuate and concentric with the center of oscillation O of the drive connection 610.
In addition, the swing center O of the driving connection member 610 is the swing center of the fixing member 630, that is, the driving connection member 610 and the fixing member 630 are sleeved on the same shaft, and the shaft center of the shaft is the swing center O of the driving connection member 610 and the fixing member 630.
The movable contact connection 620 and the driving connection 610 are connected in tension by an elastic member 650. That is, one end of the movable contact connection 620 is connected to the elastic member 650 and the other end is connected to the movable contact part 723 while the connection hole 621 is located at one end of the connection elastic member 650.
Referring to fig. 2, before the jump, i.e., when the locking member 640 is connected to the connection hole 621 of the movable contact connection member 620 and the locking hole 631 of the fixing member 630, the distance from the locking member 640 to the swing center O of the driving connection member 610 is smaller than the distance from the jump outer wall 612 of the driving connection member 610 to the swing center O of the driving connection member 610, wherein the distance from the locking member 640 to the swing center O is the distance from the closest portion of the locking member 640 to the swing center O. Since the distance from the locking member 640 to the swing center O is smaller than the distance from the kick outer wall 612 to the swing center O, and the driving connection member 610 and the moving contact connection member 620 are blocked by the kick outer wall 612 through the locking member 640, the moving contact connection member 620 is fixed in the receiving groove 611. The relative positions of the driving connector 610 and the movable contact connector 620 are fixed by the fixing member 630 and the locking member 640, and the movement of the driving connector 610 drives the movement of the movable contact connector 620.
Referring to fig. 3, when the locking member 640 is coupled to the coupling hole 621 of the movable contact coupling member 620 and the snap hole 632 of the fixing member 630, the distance from the locking member 640 to the swing center O of the driving coupling member 610 is equal to or greater than the distance from the snap outer wall 612 of the driving coupling member 610 to the swing center O of the driving coupling member 610, wherein the distance from the locking member 640 to the swing center O is the distance from the nearest portion of the locking member 640 to the swing center O. Since the distance from the locking member 640 to the swing center O is equal to or greater than the distance from the kick outer wall 612 to the swing center O, and the driving connection member 610 and the movable contact connection member 620 are tensioned by the elastic member 650, the locking member 640 brings the movable contact connection member 620 out of the accommodating groove 611 and moves upward along the arc-shaped kick outer wall 612, so that the movable contact portion 723 connected to the movable contact connection member 620 is rapidly separated from the stationary contact portion 300 to complete the kick.
At the point of the jump, the securing member 630 rotates counterclockwise along with the locking member 640 along the swing center O. When the external force applied to the fixing member 630 is removed, it drives the locking member 640 and the movable contact connection member 620 to rotate clockwise around the swing center O, and finally fixes the locking member 640 in the locking hole 631, and the movable contact connection member 620 returns to the accommodating groove 611 of the driving connection member 610.
The fixing member 630 further includes a kick trigger arm 633, as shown in fig. 1 to 3, when a force is applied to the kick trigger arm 633, the kick trigger arm 633 drives the fixing member 630 to rotate counterclockwise around the swing center O, and the locking member 640 moves from the locking hole 631 to the kick hole 632 of the fixing member 630 to move from the locking position to the kick position, and thereafter, as described above, a kick process occurs.
Second embodiment
Fig. 5 to 7 are schematic structural views of a second embodiment of the present invention, wherein fig. 7 is a cross-sectional view of fig. 6 to show the structure and working process of the fixing member. The snap assembly 800 includes a drive connector 810, a movable contact connector 820, a stationary member 830, and a locking member 840. The driving link 810 is swingably coupled to the housing, and includes a receiving groove 811. The movable contact connector 820 is connected to the movable contact portion 723, which includes a connection hole 821.
The fixing member 830 is swingably connected to the housing and includes a first fixing member 833 and a second fixing member 834. The first fixing member 833 is swingably coupled to the housing and has a latch 833a. The second fixing member 834 has a clamping groove 834a corresponding to the clamping tooth 833a of the first fixing member 833. One end of the first fixing member 833 is rotatably connected with one end of the second fixing member 834, the other ends of the first fixing member 833 and the second fixing member 834 are respectively provided with a latch 833a and a slot 834a, and the locking member 840 penetrates through the connecting hole 834b of the second fixing member 834 with the slot 834a side and the connecting hole 821 of the movable contact connecting member 820.
Before the jump, the fixing member 830 is located at the locking position, and at this time, the latch 833a of the first fixing member 833 is correspondingly clamped in the latch 834a of the second fixing member 834, so as to lock the locking member 840 in the accommodating groove 811 of the driving connecting member 810, and further lock the moving contact connecting member 820 in the accommodating groove 811 of the driving connecting member 810. The driving link 810 moves to move the movable contact link 820, thereby driving the movable contact part 723 connected to the movable contact link 820 to move.
When the snap is over, the fixing member 830 is located at the snap position, the first fixing member 833 is forced to swing, the latch 833a of the first fixing member 833 is separated from the latch 834a of the second fixing member 834, the locking member 840 is in pressed contact, and is separated from the accommodating groove 811 of the driving connector 810, so that the movable contact connector 820 is separated from the accommodating groove 811 of the driving connector 810.
The drive connection 810 further comprises a snap outer wall 812, the snap outer wall 812 being connected to the receiving groove 811. The snap outer wall 812 is arcuate and concentric with the center of oscillation O of the drive connection 810.
In addition, the swing center O of the driving connection member 810 is the swing center of the first fixing member 833, that is, the driving connection member 810 and the first fixing member 833 are sleeved on the same shaft, and the shaft center of the shaft is the swing center O of the driving connection member 810 and the first fixing member 833. One end of the second fixing member 834 is rotatably coupled to the shaft, except that the second fixing member 834 is coupled to the shaft through a long hole.
The movable contact point coupler 820 and the driving coupler 810 are connected in tension by an elastic member 850. That is, one end of the movable contact link 820 is connected to the elastic member 850 and the other end is connected to the movable contact part 723 while the connection hole 821 is located at one end of the connection elastic member 850.
The working process of the embodiment is as follows: before the jump, the latch 833a of the first fixing member 833 is snapped into the latch slot 834a of the second fixing member 834, so that when the locking member 840 is fixed in the accommodating slot 811 of the driving connector 810, the distance from the locking member 840 to the swing center O of the driving connector 810 is smaller than the distance from the jump outer wall 812 of the driving connector 810 to the swing center O of the driving connector 810, wherein the distance from the locking member 840 to the swing center O is the distance from the closest part of the locking member 840 to the swing center O. Since the distance from the locking piece 840 to the swing center O is smaller than the distance from the kick outer wall 812 to the swing center O, the driving connector 810 and the moving contact connector 820 are blocked by the kick outer wall 812 through the locking piece 840 to fix the moving contact connector 820 in the accommodating groove 811. The relative positions of the driving connector 810 and the movable contact connector 820 are fixed by the first fixing member 833, the second fixing member 834 and the locking member 840, and the driving connector 810 moves to drive the movable contact connector 820 to move.
When the jump is performed, the latch 833a of the first fixing member 833 is separated from the latch 834a of the second fixing member 834, and the distance from the locking member 840 to the swing center O of the driving connection member 810 is equal to or greater than the distance from the jump outer wall 812 of the driving connection member 810 to the swing center O of the driving connection member 810, wherein the distance from the locking member 840 to the swing center O is the distance from the nearest part of the locking member 840 to the swing center O. Since the distance from the locking member 840 to the swing center O is equal to or greater than the distance from the kick outer wall 812 to the swing center O, and the driving link 810 and the movable contact link 820 are tensioned by the elastic member 850, the locking member 840 brings the movable contact link 820 out of the accommodating groove 811 and moves upward along the arc-shaped kick outer wall 812, so that the movable contact portion 723 connected to the movable contact link 820 is rapidly separated from the stationary contact portion 300 to complete the kick.
At the point of the jump, the second anchor 834 rotates counterclockwise along with the locking element 840 along the center of oscillation O. When the external force applied to the first fixing member 833 is removed, the first fixing member 833 returns to its original position, and finally the latch 833a of the first fixing member 833 is clamped in the slot 834a of the second fixing member 834, the locking member 840 is fixed in the accommodating groove 811 of the driving connecting member 810, and the movable contact connecting member 820 returns to the accommodating groove 811 of the driving connecting member 810.
The first fixing member 833 further includes a kick trigger arm 833b, and when a force is applied to the kick trigger arm 833b, the kick trigger arm 833b drives the first fixing member 833 to rotate counterclockwise around the swing center O, so that the latch 833a is separated from the slot 834a of the second fixing member 834 to move from the lock position to the kick position, and thereafter, as described above, a kick process occurs.
Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
