The circuit breaker is used for connecting the internal circuit and the external power supply circuit of certain limit, and its effect is equivalent to master switch, and for the convenience of maintenance and repair, it can realize breaking apart normal or abnormal circuit to effectively protect the consumer, reduce its risk of damaging. With the intensive research and development of circuit breakers, in order to improve the automation and safety of circuit breaker control, circuit breakers capable of realizing remote control have been rapidly researched and developed. Usually, a terminal is provided in the circuit breaker, and a corresponding wire is inserted through the terminal. In the existing circuit breaker, when a wire is connected, a wiring terminal is inserted to push the elastic sheet away by means of an auxiliary tool, after the wire is inserted, the auxiliary tool is pulled out, and the elastic sheet presses the wire under the action of elasticity. The wire can be connected only by the aid of an auxiliary tool, so that the wiring operation is complicated. This application provides a binding post and circuit breaker based on this basis to improve the problem that exists.

In one aspect of the embodiment of the present invention, a connection terminal is provided, which includes a housing 10, and a conductive portion 40, an actuating member 20 and an elastic member 30 disposed on the housing 10; a wire insertion hole for inserting the wire 50 is further provided on the housing 10; the first end of the elastic element 30 is arranged on the shell 10, and the second end corresponds to the conductive part 40; the actuator 20 is provided with a locking part 22 and an abutting part 21 abutting against the elastic part 30; the actuating element 20 is driven to slide relative to the housing 10, and the abutting portion 21 drives the second end 31 of the elastic element to move away from the conductive portion 40, so that the second end 31 of the elastic element is matched and locked with the locking portion 22; the conductive wire 50 inserted into the wire insertion hole pushes the locking portion 22 to disengage from the second end 31 of the elastic element, the elastic element 30 acts on the abutting portion 21 to drive the operating element 20 to slide, and the second end 31 of the elastic element abuts against the conductive wire 50 to conduct the conductive portion 40 with the conductive wire 50.

For example, as shown in fig. 1, the terminal may include a housing 10 and various components disposed on the housing 10. Illustratively, there may be a conductive portion 40, an actuating member 20 and an elastic member 30. In order to facilitate the insertion of the conductive wire 50 into the corresponding position of the conductive portion 40, so as to facilitate the subsequent pressing of the elastic element 30 thereon, a wire insertion hole may be correspondingly formed on the housing 10, and the conductive portion 40 of the conductive wire 50 may be guided and inserted into the corresponding position of the conductive portion 40 provided on the housing 10 by the guiding of the wire insertion hole. The first end of the elastic element 30 is disposed on the housing 10, and may be fixed or detachable. The second end is disposed at a position corresponding to the conductive portion 40, so that when the lead 50 is inserted, the second end 31 of the elastic member abuts against the lead 50, and the lead is pressed against the conductive portion 40, thereby achieving a stable conductive state between the two.

The case 10 may be provided with an actuator 20, and the actuator 20 may be provided with an abutting portion 21 and a locking portion 22. The abutting part 21 is used for always keeping an abutting state with the elastic part 30, so that the elastic part 30 is pushed by the abutting part 21 synchronously moving along with the action part 20 through controlling the movement of the action part 20, and the elastic part is compressed and stored with energy. The locking part 22 is disposed on the actuating element 20 and is used for cooperating with the second end 31 of the elastic element to lock after the elastic element 30 is compressed in place, so as to lock the compressed state of the elastic element 30.

Under the driving of an external force (which may be applied by a driving end of the driver, or may be applied manually by an operator, and is not limited herein), the operating element 20 slides on the housing 10, for example, as shown in fig. 1, the sliding direction is from top to bottom, at this time, the abutting portion 21 and the locking portion 22 on the operating element 20 move synchronously with the operating element 20, and the elastic element 30 abutting against the abutting portion 21 is pushed by the abutting portion while the abutting portion 21 moves, that is, the elastic element 30 is gradually compressed to store energy. In the process of compressing and storing energy, the second end of the elastic element 30 gradually moves away from the conductive part 40, so that a space for plugging the wire is reserved between the second end 31 of the elastic element and the conductive part 40, and the subsequent wire 50 can be conveniently and smoothly plugged in. At the same time, the second end 31 of the elastic member will also move toward the locking portion 22 provided on the operating member 20. As shown in fig. 2, after the second end 31 of the elastic element moves to the locking portion 22 and contacts with the locking portion 22, the locking portion 22 locks the second end 31 of the elastic element, so as to limit the elastic element 30 to recover and release energy, and limit the second end 31 of the elastic element from moving in a direction approaching the conductive portion 40.

When the terminal is assembled and adjusted and needs to be used, the external wire 50 is inserted through the wire insertion hole formed in the housing 10 and moves to the position of the conductive portion 40 under the guidance of the wire insertion hole, as shown in fig. 3, when it moves to the locking portion 22 of the operating member 20, it will contact with the wire, and under the continuous insertion of the wire 50, the locking portion 22 is pushed to move, so that it is separated from the second end 31 of the elastic member, i.e. the limitation on the second end 31 of the elastic member is removed. The elastic element 30 starts to release energy, and under the effect of the recovery deformation, the second end 31 of the elastic element starts to gradually move towards the conductive part 40, and since the conductive wire 50 is located between the conductive part 40 and the second end 31 of the elastic element, the second end 31 of the elastic element also moves towards the conductive wire 50. Since the elastic member 30 and the abutting portion 21 of the operating member 20 are in the state of abutting at all times, the second end 31 of the elastic member moves toward the direction approaching the conducting wire 50, and at the same time, the operating member 20 is also pushed to move toward the opposite direction (i.e., the direction opposite to the moving direction of the operating member 20 pushing the elastic member 30 to compress the stored energy), for example, from bottom to top in fig. 3. At this time, the locking portion 22 on the actuating element 20 may deform under the support of the conductive wire 50 to satisfy the movement of the actuating element 20, or may deform under the support of the conductive wire 50 to satisfy the movement of the actuating element 20, and the locking portion 22 breaks away from the conductive wire 50 after deforming to a certain position, and so on, which is not limited in the present application. As shown in fig. 4, until the second end 31 of the elastic member moves to contact the conductive wire 50, a pressing force is applied to the conductive wire 50 toward the conductive portion 40, and the conductive wire 50 is pressed against the conductive portion 40 by the pressing force. Can be when the wiring through this kind of mode, thereby make elastic component 30 automatic compress tightly wire 50 by inserting wire 50 direct unblock elastic component 30 in the motion process, directly break away from the reliance to appurtenance when the wiring, and simultaneously, simplify the wiring operation, improve wiring efficiency, because elastic component 30 compresses tightly the effect, can also guarantee that the stability of conductive part 40 in wire 50 and the binding post switches on, improve the stability of both contacts, reduce the influence of external environment to its stability of connecting and switching on. It should be noted that, the locking portion 22 and the actuating element 20 may be integrally formed, or may be separately formed and then connected, where the connection mode may be a fixed connection, or may be a detachable connection, as long as the two are formed in a combined manner, so as to achieve the above-mentioned functions, and the application is not limited thereto.

For example, as shown in fig. 7 and 8, when the locking portion 22 and the operating member 20 are detachably connected, a rotating shaft 26 may be provided on the operating member 20, as shown in fig. 9, and a boss 24 may be provided on the rotating shaft 26 to enable the locking portion 22 to be restored after deformation. A groove 25 is further formed on the rotating shaft 26 to facilitate the connection of the resilient arm 224 of the locking portion 22 with the rotating shaft 26. Correspondingly, as shown in fig. 10, the locking portion 22 includes a blocking wall 221, an unlocking portion 222 and a guiding wall 223, and meanwhile, an elastic arm 224 and a connecting arm 225 are further disposed thereon, one end of the elastic arm 224 is connected to the locking portion 22, the other end is sleeved on the rotating shaft 26 and corresponds to the boss 24 and the recess 25 on the rotating shaft 26, that is, the elastic arm 224 is located in the recess 25 and abuts against the boss 24, and the connecting arm 225 is sleeved on the rotating shaft 26, so as to improve the stability of connection between the locking portion 22 and the rotating shaft 26. The elastic arm 224 is used for providing elastic potential energy for the latch portion 22 during resetting, that is, when the second end 31 of the elastic element or the conducting wire 50 pushes the latch portion 22 to move, the connecting arm 225 rotates relative to the rotating shaft 26, and the elastic arm 224 deforms under the limit abutment of the boss 24, so as to store the elastic potential energy, and when the second end 31 of the elastic element or the conducting wire 50 is separated from the latch portion 22, the whole latch portion 22 resets under the action of the elastic potential energy of the elastic arm 224.

Optionally, the locking portion 22 includes a blocking wall 221; the blocking wall 221 is adapted to snap-fit with the second end 31 of the elastic member to lock the elastic member 30 and the actuating member 20 together.

Illustratively, as shown in fig. 1, the locking portion 22 includes a blocking wall 221, and the blocking wall 221 is disposed on a side of the locking portion 22 away from the conductive portion 40, and can achieve relative locking between the elastic member 30 and the actuating member 20 by the blocking wall 221 and the second end 31 of the elastic member engaging with each other when the second end 31 of the elastic member moves to the blocking wall 221. Through the arrangement of the blocking wall 221, the stability of the clamping connection between the second end 31 of the elastic member and the blocking wall 221 can be effectively improved.

Optionally, the locking portion 22 forms an included angle with the operating element 20, and the locking portion 22 is located on one side of the operating element 20 close to the conductive portion 40; the blocking wall 221 is located on a side of the locking portion 22 away from the conductive portion 40; when the abutting portion 21 drives the second end 31 of the elastic member to move away from the conductive portion 40, the second end 31 of the elastic member can push the locking portion 22 to deform so that the second end 31 of the elastic member is engaged with the blocking wall 221.

For example, as shown in fig. 3, in order to lock the locking portion 22 and the second end 31 of the elastic member, the locking portion 22 may be disposed on a side of the operating member 20 close to the conductive portion 40, i.e., on the same side as the second end 31 of the elastic member. Meanwhile, the elastic piece and the action piece 20 are arranged at an included angle, for example, 90 degrees to 180 degrees and the like, and move synchronously with the action piece 20, so that the movement of the action piece 20 is facilitated, the synchronous movement is realized, and a corresponding space is reserved when the second end 31 of the elastic piece is close to the locking buckle part 22, so that the second end 31 of the elastic piece can be more smoothly completed and locked with the blocking wall 221 on the locking buckle part 22 in a clamping manner.

When the second end 31 of the elastic element is engaged with the blocking wall 221, the actuating element 20 is controlled to slide relative to the housing 10 from top to bottom, as shown in fig. 1, at this time, the abutting portion 21 on the actuating element 20 drives the second end 31 of the elastic element to compress, and is moved in a direction away from the conductive portion 40, that is, in a direction close to the locking portion 22, at which time, the locking portion 22 and the operating member 20 are moved in synchronization, thereby providing room for the second end 31 of the spring, which second end 31 of the spring, after approaching the locking portions 22, which will contact with the locking portion 22, and as the abutting portion 21 is pushed continuously, the second end 31 of the elastic member will push the locking portion 22 to deform the portion connected to the actuating member 20, for example, as shown in fig. 2, the locking portion 22 moves clockwise, so that the second end 31 of the elastic member continues to approach the blocking wall 221 of the locking portion 22. After the second end 31 of the elastic member passes over the stopping wall 221 of the locking portion 22, the locking portion 22 will rebound under the action of its own elastic potential energy, so that the stopping wall 221 corresponds to the second end 31 of the elastic member and the stopping wall 221, at this time, the external force applied to the operating member 20 is removed, and the second end 31 of the elastic member and the stopping wall 221 are tightly attached to complete the limit of the elastic member 30.

Optionally, an unlocking portion 222 is further disposed at one end of the locking portion 22 close to the conductive portion 40; the unlocking portion 222 is used for moving under the pushing of the wire 50 to drive the locking portion 22 to disengage from the second end 31 of the elastic member.

For example, as shown in fig. 3, in order to achieve a smoother usage experience, an unlocking portion 222 may be further provided at one end of the locking portion 22 close to the conductive portion 40. The wire 50 is inserted into the wire insertion hole under the condition that the locking part and the elastic part 30 realize the locking state by matching and clamping the blocking wall 221 on the locking part 22 and the second end 31 of the elastic part, when the wire 50 contacts the unlocking part 222 on the locking part 22, the unlocking part 222 can be pushed by using the structural strength of the wire 50, and then the locking part 22 is driven to move integrally, so that the blocking wall 221 on the locking part 22 is separated from the second end 31 of the elastic part, namely, the limitation of the two parts is released. After the limit is released, the characteristic that the elastic piece 30 releases elastic potential energy can be automatically utilized, the second end of the elastic piece 30 is automatically pressed on the conducting wire 50, and therefore the conducting wire 50 and the conducting part 40 are stably conducted. This kind of unblock mode is more high-efficient and rationalize, has improved the efficiency of binding post wiring.

Optionally, the locking portion 22 further includes a guide wall 223; the guide wall 223 is disposed opposite to the blocking wall 221 for guiding the second end 31 of the elastic member to be engaged with the blocking wall 221.

As an example, a guiding wall 223 may be further disposed on the locking portion 22, wherein the guiding wall 223 may be an arc-shaped surface, an inclined surface as shown in fig. 4, and the like, and the application is not limited thereto. The guide wall 223 and the blocking wall 221 are arranged oppositely, so that when the second end 31 of the elastic member contacts the guide wall 223 on the locking part 22, the locking part 22 can be pushed to deform more smoothly, so as to guide the second end 31 of the elastic member to approach the blocking wall 221, and then to be clamped with the blocking wall to lock the second end 31 of the elastic member. As shown in fig. 1, when the second end 31 of the elastic member approaches the locking portion 22, it may first contact the guiding wall 223, and the second end 31 of the elastic member is guided to gradually approach the blocking wall 221 by the inclination angle of the inclined surface, so as to induce the gradual deformation of the locking portion 22, and improve the sliding efficiency of the two.

In addition, in order to further reduce the stress concentration when the latch 22 is deformed due to the contact, a guiding wall 223, which may be an arc-shaped surface or an inclined surface, may be correspondingly disposed at the second end 31 of the elastic member.

Optionally, a through hole 23 or a through groove is provided on the acting element 20, and the second end 31 of the elastic element penetrates out of the acting element 20 through the through hole 23 or the through groove to correspond to the conductive part 40; the through hole 23 or the side wall of the through groove forms an abutment portion 21 to abut against the elastic member 30.

Illustratively, as shown in fig. 1 and 5, a through hole 23 or a through groove may be further provided on the operating member 20, and the second end 31 of the elastic member may penetrate the operating member 20 through the through hole 23 or the through groove and correspond to the conductive portion 40, i.e., the two ends of the elastic member 30 are respectively located at two sides of the operating member 20, i.e., the operating member 20 and the elastic member 30 are disposed to intersect with each other. When action 20 moves, can carry out the butt drive to elastic component 30 through the lateral wall of through-hole 23 or logical groove to make elastic component 30 realize corresponding functions such as energy storage. Through the mode, the utilization rate of the inner space of the wiring terminal can be further improved, so that the layout among all parts is more compact, the size of the wiring terminal can be effectively reduced, and meanwhile, the miniaturization of the circuit breaker is facilitated. Note that the side wall of the through hole 23 or the through groove forms the abutting portion 21, that is, the portion of the through hole 23 or the through groove that abuts against the elastic member 30 is the abutting portion 21.

Optionally, the abutment 21 is an arcuate abutment 21.

For example, as shown in fig. 1, the through hole 23 or the portion abutting against the elastic member 30 in the through groove is set as the arc abutting portion 21, when the abutting is pushed, the arc surface of the abutting portion 21 and the elastic member 30 can be in contact, so that the stress when the two are in contact is further reduced, and the service life of the elastic member 30 is prolonged.

Optionally, the elastic member 30 includes a supporting portion 33 and a pressing portion 32 connected to each other, a fixing hole or a fixing groove is further provided on the housing 10, the pressing portion 32 of the elastic member 30 passes through the fixing hole or the fixing groove to abut against the abutting portion 21, and the supporting portion 33 abuts against the housing 10.

As an example, the elastic member 30 may be detachably disposed on the housing 10, for example, as shown in fig. 6, the elastic member 30 is divided into a supporting portion 33 and a pressing portion 32 which are connected to each other. The supporting portion 33 is abutted against the housing 10, correspondingly, a fixing hole or a fixing groove is provided on the housing 10, the pressing portion 32 of the elastic member 30 is inserted through the fixing hole or the fixing groove and then abutted against the abutting portion 21 on the operating member 20, that is, the first end (the supporting portion 33) and the second end (the pressing portion 32) of the elastic member 30 are correspondingly provided. For example, as shown in fig. 5, when the through hole 23 or the through groove is further provided on the operating member 20, the pressing portion 32 should also pass through the through hole 23 or the through groove on the operating member 20, and further correspond to the conductive portion 40.

Optionally, a sliding hole is provided on the housing 10, and the operating member 20 is located in the sliding hole and can slide along the extending direction of the sliding hole.

For example, as shown in fig. 1, in order to provide a limit in the sliding direction when the actuator 20 slides relative to the housing 10, a sliding hole may be provided on the housing 10 along the direction in which the actuator 20 needs to slide, and the shape and size of the sliding hole should correspond to the shape and size of the actuator 20, that is, the two should be provided in a matching manner, and at the same time, in order to further improve the smoothness of the two during relative sliding, the contact surfaces of the two may be smoothed.

In an exemplary application of the terminal described above to a circuit breaker, the movement of the actuating member 20 can push the elastic member 30 to be locked with the actuating member, so as to reserve a wire insertion space in advance for inserting the wire 50, and maintain a wire insertion state. The wire 50 is inserted into a position between the second end 31 of the elastic element and the conductive part 40, and the intensity of the wire 50 is utilized to push the locking part 22 on the action element 20 to move, so that the second end 31 of the elastic element is unlocked, and the limit of the second end 31 of the elastic element is released. Therefore, the purpose that the elastic piece 30 presses the conducting wire 50 to the conducting part 40 under the action of elastic potential energy is achieved, the conducting wire and the conducting part are kept in a good contact conduction state, and meanwhile, the operation that the connecting terminal of the circuit breaker is connected into the conducting wire 50 is simplified.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
