Description

Technical Field

[0001] The present application relates to a push-type solid-state circuit breaker. Background Art

[0002] In the existing push-type solid-state circuit breaker, when the closing button is pressed to the closing position, the moving contact contacts the static contact. Press the opening button to perform the opening action, the opening button moves to the opening position and unlocks the locking piece on the closing button. However, if the closing button is always pressed due to unexpected reasons at this time, the closing button cannot return to the initial position under the action of its reset spring, and the moving contact cannot be separated from the static contact. At this time, the opening position can return to the initial position under the action of its reset spring, and then the locking piece moves to the locking position again, locking the closing button in the closing position. In this case, even if the external force pressing the closing button disappears, the closing button cannot move to the initial position. Only by pressing the opening button again to move the locking piece to the unlocking position can the closing button return to the initial position. This makes the operation complicated and adds additional labor process. Summary of the invention

[0003] In order to solve the above problems, the present application provides a push-type solid-state circuit breaker, comprising:

[0004] A closing button is movably arranged on the housing and can move along a first direction between an initial closing position and a closing position;

[0005] The opening button is movably arranged on the housing and can move along a first direction between an opening initial position and an opening position.

[0006] The moving contact is connected to the closing button and can move with the closing button to separate and contact with the stationary contact;

[0007] The linkage plate is arranged on the housing via a spring and can move along the second direction between an extended position and a restored position. When the closing button is in the initial closing position, the linkage plate is in the extended position. When the closing button is in the closing position, the linkage plate is in the restored position.

[0008] When the linkage plate is in the recovery position and the opening button is in the opening position, a part of the linkage plate abuts against the opening button and blocks the opening button from returning from the opening position to the opening initial position. Only when the closing button returns from the closing position to the closing initial position, causing the linkage plate to move from the recovery position to the extended position, the linkage plate allows the opening button to return from the opening position to the opening initial position.

[0009] Advantageously, the invention further comprises: a locking member, movably arranged on the housing, capable of moving between a locked position and an unlocked position along a second direction perpendicular to the first direction, the locking member being biased toward the locked position, in which the locking member is configured to lock a closing button in the closed position, and when the opening button is in the opening position, the opening button can drive the locking member from the locked position to the unlocked position, thereby releasing the lock on the closing button.

[0010] When the closing button is in the initial closing position, the moving contact is separated from the static contact. When the closing button moves from the initial closing position toward the closing position, it can overcome the bias of the locking piece and move the moving contact toward the static contact. After the moving contact and the static contact contact, the locking piece returns to the locking position and keeps the closing button in the closing position.

[0011] Advantageously, the linkage plate comprises:

[0012] ontology;

[0013] A first contour notch is formed on the body, the first contour notch having a first contour wall, the shape of the first contour wall being designed so that when the closing button moves between the initial closing position and the closing position, a part of the closing button abuts against the first contour wall of the first contour notch, so that the linkage plate moves between the extended position and the restored position;

[0014] A second contour notch is formed on the body, the second contour notch having a second contour wall, the shape of the second contour wall being designed to block the opening button from returning to its initial position from the opening position when the linkage plate is in the recovery position and the opening button is in the opening position

[0015] The first contour wall and the second contour wall are respectively formed on a side of the first contour notch and the second contour notch away from the spring.

[0016] Advantageously, the first contour wall comprises:

[0017] first vertical wall;

[0018] A first inclined wall, a first vertical wall and the first inclined wall are arranged along a first direction, and the first inclined wall is located below the first vertical wall and connected to the first vertical wall,

[0019] The inclination direction of the first inclined wall is arranged so that a connection end of the first inclined wall and the first vertical wall is closer to the spring than the other end of the first inclined wall opposite to the connection end.

[0020] Advantageously, in the extended position of the linkage plate, the first vertical wall abuts against a portion of the closing button in the initial position.

[0021] During the movement of the closing button from the initial closing position toward the closing position, the part of the closing button is separated from the abutment with the first vertical wall, abuts with the first inclined wall and moves along the first inclined wall, so that the linkage plate moves from the extended position toward the restored position under the action of the spring.

[0022] During the movement of the closing button from the closing position toward the initial closing position, this part of the closing button abuts against the first inclined wall and moves along the first inclined wall, thereby pushing the inclined wall and then pushing the linkage plate to move from the recovery position toward the extended position. When the closing button moves to the initial closing position, the first part of the closing button disengages from the abutment with the first inclined wall and abuts against the first vertical wall.

[0023] Advantageously, the second contour wall comprises:

[0024] a second vertical wall;

[0025] a second inclined wall;

[0026] The horizontal wall, the second vertical wall, the second inclined wall and the horizontal wall are arranged along the first direction and connected in sequence,

[0027] The inclination direction of the second inclined wall is set so that one end of the second inclined wall connected to the horizontal wall is closer to the spring than one end of the second inclined wall connected to the second vertical wall.

[0028] Advantageously, in the restored position of the linkage plate, the second vertical wall abuts against a portion of the opening button in the initial position.

[0029] During the movement of the opening button from the opening initial position toward the opening position, the part of the opening button is separated from the contact with the second vertical wall, and contacts the second inclined wall and moves along the second inclined wall, and the opening button pushes the linkage plate toward the extended position of the linkage plate. When the part of the opening button is separated from the contact with the second inclined wall, the linkage plate returns to the recovery position under the action of the spring, so that the part of the opening button is located below the horizontal wall.

[0030] After the linkage plate moves from the recovery position to the extension position, the horizontal wall is not above the portion of the opening button, and the opening button can return from the opening position to the opening initial position under the action of its reset spring.

[0031] Advantageously, the closing button comprises a first protrusion protruding toward the linkage plate, wherein the first protrusion is configured to cooperate with a first contour wall of the linkage plate.

[0032] The opening button comprises a second protrusion protruding toward the linkage plate, and the second protrusion is configured to cooperate with the second contour wall of the linkage plate.

[0033] Advantageously, the first contour wall further comprises another vertical wall, which is located below the first inclined wall and connected to the other end of the first inclined wall. In the recovery position of the linkage plate, the other vertical wall abuts against a portion of the closing button in the closing position.

[0034] Advantageously, the second contour wall further comprises another vertical wall, which is located below the horizontal wall and connected to the horizontal wall. In the restored position of the linkage plate, the other vertical wall abuts against a portion of the opening button in the opening position.

[0035] Advantageously, the first contour notch and the second contour notch are open on one side along the first direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the purpose, technical solution and advantages of the technical solution of the present disclosure clearer, the technical solution of the embodiment of the present disclosure will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present disclosure. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0043] Compared to the embodiments shown in the drawings, feasible implementations within the scope of the present disclosure may have fewer components, other components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0044] Unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which the present disclosure belongs. The words "first", "second" and similar words used in the patent specification and claims of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. When the number of components is not specified, the number of components may be one or more; similarly, words such as "one", "the", "said" and the like do not necessarily indicate a quantity limitation. Words such as "include" or "comprise" and the like mean that the element or object appearing before the word includes the element or object listed after the word and its equivalent, without excluding other elements or objects. Words such as "install", "set", "connect" or "connected" and the like are not limited to physical or mechanical installation, setting, connection, but may include electrical installation, setting, connection, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate the relative position relationship when the device is in use or the position relationship shown in the drawings. When the absolute position of the described object changes, the relative position relationship may also change accordingly.

[0045] Figure 1A schematic diagram of a push-type solid-state circuit breaker according to the present application is shown, and the push-type solid-state circuit breaker includes a closing button 11, which can move between the initial closing position and the closing position in a first direction (vertical direction in the figure), and a moving contact 13 is connected to the closing button 11 and can move with the closing button. When the closing button is pressed and moves from the initial closing position to the closing position, the moving contact 13 moves to contact with the static contact 14, thereby closing the circuit. When the closing button 11 moves to the closing position, the closing button 11 will abut against the locking member 15 in the locking position, and the locking member blocks the closing button 11 from returning to the initial closing position. The locking member 15 is mounted to the housing via a spring 151, is biased toward the locking position, and can move between the locking position and the unlocking position in a second direction perpendicular to the first direction (horizontal direction in the figure). In the unlocking position of the locking member, the locking member is disengaged from the abutment against the closing button 11, thereby allowing the closing button to return to the initial closing position.

[0046] Specifically, in this example, the closing button 11 includes a first conical portion 111 protruding toward the locking piece, and the first conical portion 111 includes a straight wall and an inclined wall. The locking piece 15 includes a second conical portion protruding toward the closing button, and the second conical portion also includes a straight wall and an inclined wall. The inclined wall of the first conical portion faces the inclined wall of the second conical portion, so that when the closing button moves from the initial closing position toward the closing position, the inclined wall of the first conical portion abuts against the inclined wall of the second conical portion and pushes the locking piece 15 toward the unlocking position. When the first conical portion moves past the second conical portion, the locking piece 15 returns to the locked position under the action of the spring, and the straight wall of the conical portion of the locking piece 15 is located above the straight wall of the first conical portion, blocking the closing button from returning to the initial closing position.

[0047] The above only describes an example of keeping the closing button in the closing position, and the form of cooperation between the closing button and the locking member is not limited to this. Those skilled in the art can design a suitable form to achieve the cooperation between the closing button and the locking member as needed.

[0048] The push-type solid-state circuit breaker also includes an opening button 12, which can move along a first direction between an initial position and an opening position. In the closed state of the push-type solid-state circuit breaker, when opening is required, the opening button is pressed and moves from the initial position to the opening position. When the opening button 12 moves to the opening position, the opening button pushes the locking member to the unlocking position, so that the closing button can move back to the initial position. These processes will be described in detail below.

[0049] The push-type solid-state circuit breaker also includes a linkage plate 16, which is arranged on the housing via a spring 161 and can move between an extended position and a restored position. In the initial closing position of the closing button, the linkage plate is in the extended position, and in the closing position of the closing button, the linkage plate is in the restored position. In addition to the fully relaxed state of the spring 161, the "restored position" may also include the spring 161 still being in a stretched state, but at this time the stretched state of the "restored position" is not as good as the stretched state of the "extended position".

[0050] When the linkage plate is in the recovery position and the opening button is in the opening position, a part of the linkage plate abuts against the opening button and blocks the opening button from returning from the opening position to the opening initial position. Only when the closing button returns from the closing position to the closing initial position, causing the linkage plate to move from the recovery position to the extended position, the linkage plate allows the opening button to return from the opening position to the opening initial position.

[0051] like Figure 5 As shown, the linkage plate 16 includes a body 161, a first contour notch 162 is formed on the body, the first contour notch has a first contour wall 164, the shape of the first contour wall is designed to when the closing button moves between the initial closing position and the closing position, the closing button abuts against the first contour wall of the first contour notch, so that the linkage plate moves between the extended position and the restored position. A second contour notch 163 is formed on the body, the second contour notch has a second contour wall 165, the shape of the second contour wall is designed to block the opening button from returning from the opening position to the initial opening position when the linkage plate is in the restored position and the opening button is in the opening position.

[0052] The first contour wall 164 includes a first vertical wall 1641, a first inclined wall 1642, and another vertical wall 1643, which are connected in sequence along a first direction. The first inclined wall 1642 is located below the first vertical wall 1641, and the other vertical wall 1643 is located below the first inclined wall 1642. The inclination direction of the first inclined wall 1642 is set so that the connecting end of the first inclined wall and the first vertical wall is closer to the spring 161 than the other end of the first inclined wall opposite to the connecting end (the other end is connected to the other vertical wall).

[0053] The second contour wall 165 includes a second vertical wall 1651, a second inclined wall 1652, a horizontal wall 1653 and another vertical wall 1654 arranged along the first direction and connected in sequence, and the inclination direction of the second inclined wall is set so that the end of the second inclined wall connected to the horizontal wall is closer to the spring 161 than the end of the second inclined wall connected to the second vertical wall.

[0054] The first contour wall and the second contour wall are respectively formed on a side of the first contour notch and the second contour notch away from the spring.

[0055] The operation process of the push-type solid-state circuit breaker is described below for a better understanding of the present application.

[0056] Figure 1 The push-type solid-state circuit breaker is shown in the open state, the closing button and the opening button are respectively in the closed initial position and the open initial position, and the linkage plate is in the extended position. The closing button 11 includes a first protrusion 112 extending toward the linkage plate, and the opening button includes a second protrusion 121 extending toward the linkage plate. At this time, the first protrusion 112 abuts against the first vertical wall 1641, and the second protrusion 121 is separated from the second vertical wall 1651.

[0057] When the closing button is pressed downward in the first direction to move to the closing position, the first protrusion 112 first moves along the first vertical wall 1641, then breaks away from the contact with the first vertical wall 1641, then abuts against the first inclined wall 1642 and moves along the first inclined wall 1642, and finally breaks away from the contact with the first inclined wall 1642 and abuts against another vertical wall 1643. In this process, the linkage plate 16 moves from the extended position to the restored position under the action of the spring 161, and the second protrusion 121 abuts against the second vertical wall 1651, as shown in FIG. Figure 2 As shown, the moving contact contacts the static contact, and the solid-state circuit breaker is in the closed state. In addition, in this process, as described above, the first conical portion 111 of the closing button abuts against the second conical portion of the locking member, and overcomes the biasing force of the spring 151 to move the locking member toward the unlocking position. After the first conical portion 111 moves past the second conical portion, the closing button moves to its closed position and is locked in the closed position by the locking member.

[0058] Next, when the gate needs to be opened, the opening button is pressed downward along the first direction. When the opening button moves to the opening position, the opening button causes the locking member to move from the locking position to the unlocking position (for example, the opening button includes an inclined wall that cooperates with the second conical portion of the locking member to push the locking member to the unlocking position. This process is well known to those skilled in the art and can be modified as needed. It is not the focus of this article and is therefore not described in detail). Figure 3 In this process, the second protrusion 121 of the opening button first moves along the second vertical wall 1651, then breaks away from the contact with the second vertical wall 1651 and contacts the second inclined wall 1652, and moves along the second inclined wall 1652, so that the second protrusion pushes the second inclined wall 1652 and then pushes the linkage plate toward the extended position. After the second protrusion breaks away from the contact with the second inclined wall, the linkage plate returns to the recovery position under the action of the spring 161, so that the second protrusion is located below the horizontal wall 1653 and contacts the other vertical wall 1654 (alternatively, the second protrusion may not contact the other vertical wall).

[0059] exist Figure 3In the case of a lock, since the locking member has moved to the unlocked position, the closing button can return to the initial closing position under the action of its reset spring (not shown). However, if the closing button is pressed due to an unexpected reason and cannot return to the initial closing position, the opening button cannot return to the initial opening position. Only when the closing button returns to the initial closing position can the opening button return to the initial opening position, as described below.

[0060] like Figure 4 As shown, without any external force pressing the closing button, the closing button can move along the other vertical wall, the first inclined wall and the first vertical wall in sequence under the action of its reset spring to reach the closed initial position. When the first protrusion moves along the first inclined wall, it can push the linkage plate from the recovery position to the extended position. Since the linkage plate moves to the extended position, the horizontal wall 1653 is not located above the second protrusion, that is, it will not block the movement of the opening button toward the opening initial position. Then, the opening button can return to the opening initial position under the action of its reset spring (not shown), and finally reach the closed initial position. Figure 1 Status shown.

[0061] In this example, the first contour notch and the second contour notch are open on one side along the first direction. However, the first contour notch and the second contour notch may also not be open along the first direction, in which case the first protrusion and the second protrusion can move in the closed first contour notch and the second contour notch.

[0062] Through the linkage plate of the present application, in the closed state of the push-type solid-state circuit breaker, when the opening button is pressed to the opening position for opening, a part of the linkage plate can abut against the opening button and block the opening button from returning from the opening position to the opening initial position. Only when the closing button returns from the closing position to the closing initial position, the linkage plate allows the opening button to return from the opening position to the opening initial position. In other words, when the closing button cannot return from the closing position to the closing initial position due to unexpected reasons, the opening button cannot return to the opening initial position either. When the external force pressing the closing button disappears so that the closing button returns to the closing initial position, the opening button returns to the opening initial position. This ensures the coordinated operation of the closing button and the opening button, reduces the operation steps when the closing button is accidentally stuck, and simplifies the operation.

[0063] Although the present invention has been described in the specification and illustrated in the drawings with reference to various embodiments, those skilled in the art will appreciate that the above embodiments are merely preferred implementations, and certain technical features in the embodiments may not be necessary for solving specific technical problems, and thus these technical features may be absent or omitted without affecting the solution of the technical problems or the formation of technical solutions; moreover, the features, elements and / or functions of one embodiment may be appropriately combined, coupled or coordinated with the features, elements and / or functions of one or more other embodiments, unless the combination, coupling or coordination is obviously not feasible.
