Description

Technical Field

[0001] The invention relates to the technical field of low-voltage electrical switches, and in particular to a wiring terminal and a circuit breaker. Background Art

[0002] With the advancement of science and technology, people's living standards have been rapidly improved, and there is a higher demand for household electricity safety. Miniature circuit breakers can be installed in terminal distribution lines due to their small size. At the same time, they can also connect, carry and disconnect currents under normal or abnormal circuit conditions, forming effective protection for lines and electrical equipment. When using a circuit breaker, it is also necessary to set a wiring terminal to connect the wire to complete the circuit connection.

[0003] When connecting a wire to an existing terminal, an auxiliary tool is required to insert the terminal to push the spring piece open, and then the auxiliary tool is pulled out after the wire is inserted. The spring piece will press the wire tightly under the action of elasticity. Since an additional auxiliary tool is required to complete the connection of the wire, the wiring operation is relatively cumbersome. Summary of the invention

[0004] The object of the present invention is to provide a wiring terminal and a circuit breaker to address the deficiencies in the above-mentioned prior art, so as to solve the problem that the existing wiring terminals need to use auxiliary tools when connecting wires, resulting in cumbersome wiring.

[0005] To achieve the above purpose, the technical solution adopted by the embodiment of the present invention is as follows:

[0006] According to one aspect of an embodiment of the present invention, there is provided a terminal block, comprising: a shell and a wiring portion, a control member, a locking member and an elastic member arranged on the shell; a wiring hole for receiving a wire is also arranged on the shell; a first end of the elastic member is arranged on the shell, and a second end corresponds to the wiring portion; a supporting portion and a locking portion are respectively arranged on the control member; the control member is driven to slide relative to the shell, the supporting portion drives the second end of the elastic member away from the wiring portion, and the locking portion approaches the locking member to cooperate with the locking; the wire connected to the wiring hole drives the locking member to move to disengage from the locking portion, the elastic member acts on the supporting portion to drive the control member to slide, and the second end of the elastic member resists the wire to make the wire and the wiring portion conductive.

[0007] Optionally, a side wall of the locking portion away from the locking piece is a blocking wall; a side wall of the locking piece away from the locking portion is a clamping wall; when the locking portion moves toward the locking piece, the blocking wall clamps with the clamping wall to make the locking portion and the locking piece cooperate and lock.

[0008] Optionally, the locking member includes a locking portion and an energy storage portion that are interconnected; the locking portion is rotatably arranged on the shell, the locking portion is located in the sliding direction of the locking portion and the clamping wall is located on the locking portion; when the locking portion slides close to the locking portion, the locking member is driven to rotate along a first direction to allow the energy storage portion to store energy, and when the blocking wall and the clamping wall correspond, the energy storage portion releases energy to drive the locking member to rotate along a second direction to allow the clamping wall to clamp with the blocking wall; the first direction and the second direction are opposite.

[0009] Optionally, the locking portion and the locking portion are both rigid parts.

[0010] Optionally, a side wall of the locking portion close to the locking element is a first guide wall; a side wall of the locking element close to the locking portion is a second guide wall; the first guide wall and the second guide wall cooperate to guide the engagement of the engaging wall and the blocking wall.

[0011] Optionally, a through hole or a through slot is provided on the control member, and the second end of the elastic member passes through the through hole or the through slot and out of the control member to correspond to the wiring portion; the side wall of the through hole or the through slot forms a supporting portion to abut against the elastic member.

[0012] Optionally, the abutting portion is an arc-shaped abutting portion.

[0013] Optionally, the elastic member includes a supporting portion and a pressing portion connected to each other, and a fixing hole or a fixing groove is further provided on the shell, the pressing portion of the elastic member passes through the fixing hole or the fixing groove to abut against the abutting portion, and the supporting portion abuts against the shell.

[0014] Optionally, a sliding hole is provided on the shell, and the control member is located in the sliding hole and can slide along the extension direction of the sliding hole.

[0015] Another aspect of the embodiments of the present invention provides a circuit breaker, comprising any one of the above-mentioned connection terminals.

[0016] The beneficial effects of the present invention include:

[0017] The present invention provides a wiring terminal, comprising a housing and a wiring hole arranged on the housing. An elastic member is also arranged on the housing, wherein the first end of the elastic member is arranged on the housing, and the second end corresponds to the wiring portion. A control member is also arranged on the housing, and a supporting portion and a locking portion are respectively formed on the control member. The supporting portion always supports the elastic member. The locking portion is used to cooperate with a separately arranged locking member, thereby realizing the locking or unlocking of the control member, so that the second end of the elastic member is in a loose state when the control member is in a locked state, and in a compressed state when the control member is in an unlocked state. When the driving control member slides relative to the housing, the supporting portion located on the control member pushes the elastic member to gradually store elastic potential energy, at which time, the second end of the elastic member gradually moves away from the wiring portion, thereby providing a space for inserting the connected wire. In the process of sliding of the control member, the locking portion located on the control member also gradually approaches the locking member arranged on the housing, that is, when the locking portion approaches the locking member, the elastic member is also gradually pushed away from the wiring portion by the supporting portion and stores energy. Until the locking part on the control member contacts and locks with the locking member, at which time the control member is locked, the abutting part stops moving and the elastic member is in a compressed energy storage state. When the wire is connected from the wiring hole of the wiring terminal, one end of the wire contacts the locking piece, thereby using its own structural strength to push the locking piece to move, so that the locking part that was originally in a locked state with the locking piece is disengaged. At this time, the elastic part begins to release the stored elastic potential energy, and the second end of the elastic part begins to move in the direction close to the wiring part. Since the abutting part always abuts against it, when the elastic part moves, it will drive the abutting part to move in the opposite direction until the second end of the elastic part contacts the connected wire and uses its own elastic potential energy to press it against the wiring part and stop moving. At this time, the wire will always keep in contact with the wiring part under the action of the second end of the elastic part. In this way, when wiring, the elastic part can be directly unlocked by the inserted wire during the movement so that the elastic part automatically presses the wire, directly getting rid of the dependence on auxiliary tools during wiring. At the same time, the wiring operation is simplified and the wiring efficiency is improved. Due to the pressing effect of the elastic part, the stability of the conduction between the two can also be improved, thereby improving the stability of the wiring terminal.

[0018] The present invention also provides a circuit breaker, wherein the above-mentioned wiring terminal is arranged in the circuit breaker, and the wire connected can be compressed by the second end of the elastic member to fix the wire, so that the wire and the wiring part can maintain a stable conductive state. The elastic member can be directly unlocked by inserting the wire, so that it automatically compresses the wire, which can effectively simplify the operation of inserting the wire into the wiring terminal in the circuit breaker.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed, but merely represents selected embodiments of the present invention. It should be noted that, in the absence of conflict, the various features in the embodiments of the present invention can be combined with each other, and the combined embodiments are still within the scope of protection of the present invention.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0030] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0032] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] According to one aspect of an embodiment of the present invention, there is provided a terminal block, comprising: a housing 100, and a wiring portion 200, a control member 300, a locking member 500 and an elastic member 400 arranged on the housing 100; a wiring hole for receiving a wire 600 is also arranged on the housing 100; a first end of the elastic member 400 is arranged on the housing 100, and a second end corresponds to the wiring portion 200; a holding portion 310 and a locking portion 320 are respectively arranged on the control member 300; the control member 300 is driven to slide relative to the housing 100, the holding portion 310 drives the second end 410 of the elastic member away from the wiring portion 200, and the locking portion 320 approaches the locking member 500 to cooperate with the locking; the wire 600 connected to the wiring hole drives the locking member 500 to move to disengage from the locking portion 320, the elastic member 400 acts on the holding portion 310 to drive the control member 300 to slide, and the second end 410 of the elastic member abuts against the wire 600 to make the wire 600 conductive with the wiring portion 200.

[0034] For example, Figure 1 As shown, the terminal comprises a housing 100, and a wiring hole is provided on the housing 100, so that an external wire 600 can be connected to the inside of the housing 100 from the wiring hole until the wire 600 corresponds to the wiring portion 200 provided on the housing 100. An elastic member 400 is also provided on the housing 100, and a first end of the elastic member 400 is provided on the housing 100, and a second end corresponds to the wiring portion 200, so that the wire 600 corresponding to the wiring portion 200 can be pressed against the wiring portion 200 by the second end 410 of the elastic member later, so that the two maintain a good conductive state.

[0035] The housing 100 is also provided with a control member 300, on which a resisting portion 310 and a locking portion 320 are respectively formed. The resisting portion 310 is always resisted against the elastic member 400. The locking portion 320 is used to cooperate with a separately provided locking member 500, so as to achieve locking or unlocking of the control member 300, so that the second end 410 of the elastic member is in a loose state when the control member 300 is in a locked state, and in a compressed state when the control member 300 is in an unlocked state.

[0036] When the driving control member 300 slides relative to the housing 100, for example Figure 1The external force drives the control member 300 to slide from top to bottom, and the abutting portion 310 on the control member 300 pushes the elastic member 400 to deform so that it gradually stores elastic potential energy. At this time, the second end 410 of the elastic member gradually moves away from the wiring portion 200, thereby providing a space for the connected wire 600 to be inserted. During the sliding process of the control member 300, the locking portion 320 on the control member 300 also gradually approaches the lock member 500 provided on the housing 100, that is, when the locking portion 320 approaches the lock member 500, the elastic member 400 is also gradually pushed away from the wiring portion 200 by the abutting portion 310 and stores energy. Until the locking portion 320 on the control member 300 and the lock member 500 contact and lock together, at this time, the control member 300 is locked, the abutting portion 310 stops moving and the elastic member 400 is in a compressed energy storage state.

[0037] like Figure 2 As shown, when the wire 600 is connected from the wiring hole of the wiring terminal, one end of the wire 600 contacts the locking member 500, thereby using its own structural strength to push the locking member 500 to move, so that the locking portion 320 that was originally in a locked state with the locking member 500 is disengaged. At this time, the elastic member 400 begins to release the stored elastic potential energy, and the second end 410 of the elastic member begins to move toward the wiring portion 200. Since the abutting portion 310 always abuts against it, when the elastic member 400 moves, it will drive the abutting portion 310 to move in the opposite direction (that is, opposite to the movement direction of the abutting portion 310 when it is close to the locking member 500 to achieve locking). For example Figure 3 In the process, the elastic member 400 moves from bottom to top until the second end 410 of the elastic member contacts the connected wire 600 and uses its own elastic potential energy to press it against the wiring portion 200 and stops moving. At this time, the wire 600 will always keep in contact with the wiring portion 200 under the action of the second end 410 of the elastic member. In this way, when wiring, the inserted wire 600 can directly unlock the elastic member 400 during movement so that the elastic member 400 automatically presses the wire 600, directly getting rid of the dependence on auxiliary tools during wiring. At the same time, the wiring operation is simplified and the wiring efficiency is improved. Due to the pressing effect of the elastic member 400, the stability of the conduction between the two can also be improved, thereby facilitating the improvement of the stability of the wiring terminal.

[0038] Optionally, a side wall of the locking portion 320 away from the locking member 500 is a blocking wall 321; a side wall of the locking member 500 away from the locking portion 320 is a clamping wall 511; when the locking portion 320 moves toward the locking member 500, the blocking wall 321 is clamped with the clamping wall 511 to make the locking portion 320 and the locking member 500 cooperate and lock.

[0039] For example, Figure 3 and 4As shown, in order to improve the stability of the locking portion 320 and the locking member 500 in the locked state, the side wall of the locking portion 320 away from the locking member 500 can also be set as a blocking wall 321, and similarly, the side wall of the locking member 500 away from the locking portion 320 can be set as a clamping wall 511. When the locking portion 320 moves toward the locking member 500, the blocking wall 321 gradually approaches the clamping wall 511, and when the two correspond to each other, they fit each other, thereby forming a stable lock. When the locking portion 320 and the locking member 500 are locked together, it also means that the control member 300 and the locking member 500 are locked together. At this time, due to the limiting relationship between the two, the abutting portion 310 located on the control member 300 can limit the elastic member 400 so that it is in a corresponding energy storage state. It should be noted that the above-mentioned locking portion 320 can be a side wall of a protrusion or a side wall of a groove, and the present application does not limit it, as long as it can cooperate with the locking member 500 to complete the limiting. Correspondingly, the locking member 500 is the same.

[0040] Optionally, the locking component 500 includes a locking portion 510 and an energy storage portion 520 that are interconnected; the locking portion 510 is rotatably disposed on the shell 100, the locking portion 510 is located in the sliding direction of the locking portion 320 and the clamping wall 511 is located on the locking portion 510; when the locking portion 320 slides close to the locking portion 510, the locking component 500 is driven to rotate along a first direction, so that the energy storage portion 520 stores energy, and when the blocking wall 321 and the clamping wall 511 correspond, the energy storage portion 520 releases energy to drive the locking component 500 to rotate along a second direction so that the clamping wall 511 is clamped with the blocking wall 321; the first direction and the second direction are opposite.

[0041] For example, Figure 3 and 6 As shown, the lock member 500 is rotatably disposed on the housing 100, and correspondingly, the lock member 500 may include a lock portion 510 and an energy storage portion 520, wherein the lock portion 510 and the energy storage portion 520 are connected to each other, and may be integrally formed, or may be separately formed and then connected to each other, and this application does not limit it. The lock portion 510 is rotatably disposed on the housing 100, and when it rotates, it can drive the energy storage portion 520 to move.

[0042] When the locking portion 320 slides close to the locking portion 510, since the locking portion 320 and the locking portion 510 are both provided with mutually engaging protrusions, when the locking portion 320 and the locking portion 510 gradually come into contact with each other, the locking member 500 will be driven to rotate along the first direction, for example Figure 1In the embodiment, the locking part 510 rotates in the clockwise direction for a certain angle. At this time, the energy storage part 520 connected to the locking part 510 will be compressed to store elastic potential energy. When the locking part 320 or the locking part 510 relatively passes over the protrusion, that is, when the blocking wall 321 on the locking part 320 and the clamping wall 511 on the locking part 510 correspond to each other, the energy storage part 520 will start to release energy, thereby driving the locking part 510 to rotate in a second direction opposite to the first direction, for example Figure 1 The middle locking part 510 rotates counterclockwise. At this time, the clamping wall 511 and the blocking wall 321 are mutually fitted and form a limit in the sliding direction of the control member 300, so that the control member 300 is in a locked state relative to the locking member 500.

[0043] In addition, the energy storage unit 520 can also be arranged at a position corresponding to the wiring unit 200, such as Figure 2 As shown, the locking part 510 and the energy storage part 520 are arranged at an angle to each other, wherein the extension direction of the energy storage part 520 intersects with the length direction of the wire 600. When the control member 300 is in a locked state relative to the locking member 500 (at this time, the elastic member 400 is in a compressed state, i.e., an energy storage state), the wire 600 is connected to the inside of the wiring terminal from the wiring hole, and when it moves to the energy storage part 520 of the locking member 500, one end of the wire 600 contacts the energy storage part 520, and under the structural strength of the wire 600 itself, the energy storage part 520 is pushed to store energy. At this time, the energy storage part 520 drives the locking part 510 to rotate along the first direction, for example Figure 2 In the middle, the locking part 511 is rotated clockwise, at this time, the locking wall 511 is separated from the blocking wall 321, that is, the locking part 510 on the locking part 500 is separated from the locking part 320 on the control part 300, and the control part 300 is unlocked and restored to a free state. At this time, the elastic part 400 releases energy, and the second end 410 of the elastic part moves toward the direction close to the wire 600 (that is, close to the wiring part 200). After it contacts the wire 600, it will press the wire 600 against the wiring part 200, thereby achieving stable conduction between the two. This method of pressing the wire 600 is more clever, using the structural strength of the wire 600 itself to unlock the elastic part 400 in the wiring terminal, thereby achieving the effect of pressing, and improving the user experience of the wiring terminal.

[0044] When the wire 600 needs to be removed, the control member 300 is driven to slide toward the locking portion 510 in the locking member 500. At this time, the abutting portion 310 on the control member 300 drives the second end 410 of the elastic member away from the wire 600, that is, releases its pressing effect on the wire 600. At this time, the wire 600 can be directly pulled out, and the energy storage portion 520 connected to the locking portion 510 begins to release energy, pushing the locking portion 510 to reset. When the locking portion 320 on the control member 300 moves to the locking position, the locking portion 320 and the locking portion 510 are locked again through the blocking wall 321 and the clamping wall 511. It is also possible not to directly pull out the wire 600, but to push the wire 600 away by the energy stored in the energy storage portion 520 in the locking member 500. After the locking portion 320 and the locking member 500 are locked again, the wire 600 is pulled out again. By setting the energy storage part 520, not only can the automatic use experience of the wire 600 being inserted into place and compressed be improved, but also the locking positions of the control part 300 and the locking part 510 can be kept constant at all times, effectively improving the accuracy and stability of the locking of the two.

[0045] Optionally, the locking portion 320 and the locking portion 510 are both rigid parts.

[0046] For example, the locking portion 320 can be a rigid part, and the locking portion 510 can also be a rigid part, which can effectively reduce the amount of hooking when the two are locked. At the same time, the stability of the two when locked is further improved. In addition, the locking portion 320 and the locking portion 510 can be plastic parts with higher hardness, or metal parts and other forms. When both are plastic parts with higher hardness, not only can the difficulty of the manufacturing process of the two be reduced, but also the manufacturing cost of the entire terminal block can be reduced.

[0047] Optionally, a side wall of the locking portion 320 close to the locking member 500 is a first guide wall 322 ; a side wall of the locking member 500 close to the locking portion 320 is a second guide wall 512 ; the first guide wall 322 and the second guide wall 512 cooperate to guide the engaging wall 511 to engage with the blocking wall 321 .

[0048] For example, in order to improve the smoothness of the locking process between the locking portion 320 and the locking member 500, the contact strength between the two is reduced, such as Figure 3 and 4 As shown, a side wall of the locking portion 320 close to the locking member 500 may be set as a first guide wall 322. Similarly, a side wall of the locking member 500 close to the locking portion 320 may be set as a second guide wall 512. The first guide wall 322 may be an arcuate surface or may be a curved surface. Figure 4 The second guide wall 512 is similar. Figure 3As shown, when the first guide wall 322 and the second guide wall 512 are both inclined surfaces, they can maintain a corresponding matching relationship with each other when the two are not in contact, so that when the control member 300 slides and drives the locking part 320 to approach the locking part 510, the first guide wall 322 located on the locking part 320 gradually approaches the second guide wall 512 located on the locking member 500. When the locking part 320 contacts the locking member 500, the two are in contact through two inclined surfaces, which effectively reduces the stress when the two are in contact, thereby increasing the service life of the control member 300 and the locking member 500.

[0049] Optionally, a through hole 323 or a through groove is provided on the control member 300 , and the second end 410 of the elastic member passes through the through hole 323 or the through groove and out of the control member 300 to correspond to the wiring portion 200 ; the side wall of the through hole 323 or the through groove forms a supporting portion 310 to abut against the elastic member 400 .

[0050] For example, Figure 4 As shown, a through hole 323 or a through slot can also be provided on the control member 300, and the extension directions of the two are consistent, and both are used for the second end 410 of the elastic member to pass through the through hole 323 or the through slot so as to correspond to the wiring portion 200, that is, the first end and the second end of the elastic member 400 are located on both sides of the control member 300, and the wiring portion 200 and the second end 410 of the elastic member are located on the same side of the control member 300. In order to achieve the abutment between the abutting portion 310 and the elastic member 400, the part of the through hole 323 or the through slot that abuts against the elastic member 400 can be the abutting portion 310. This arrangement can effectively improve the compactness of the internal layout of the terminal block, and facilitate the miniaturization of the terminal block.

[0051] Optionally, the abutting portion 310 is an arc-shaped abutting portion 310 .

[0052] For example, Figure 4 As shown, in order to further reduce the stress concentration when the abutting portion 310 and the elastic member 400 abut, the abutting portion 310 can also be set as an arc-shaped abutting portion 310, so that the arc surface of the abutting portion 310 abuts against the elastic member 400.

[0053] Optionally, the elastic member 400 includes a supporting portion 430 and a pressing portion 420 connected to each other, and a fixing hole or a fixing groove is also provided on the shell 100. The pressing portion 420 of the elastic member 400 abuts against the abutting portion 310 through the fixing hole or the fixing groove, and the supporting portion 430 abuts against the shell 100.

[0054] For example, the elastic member 400 includes a supporting portion 430 and a pressing portion 420 connected to each other, such as Figure 5As shown, a fixing hole or a fixing groove may also be provided on the shell 100, so that part of the elastic member 400 is located in the fixing hole or the fixing groove. For example, the pressing portion 420 of the elastic member 400 may pass through the fixing hole or the fixing groove and then abut against the supporting portion 310 on the control member 300, and the supporting portion 430 abuts against the shell 100. The control member 300 slides, driving the abutting portion 310 to push the pressing portion 420 close to the supporting portion 430 to complete energy storage. When a through hole 323 or a through groove is also provided on the control member 300, the pressing portion 420 also passes through the through hole 323 or the through groove on the control member 300, and then corresponds to the wiring portion 200. The elastic member 400 may be as follows Figure 5 The spring piece shown may also be a torsion spring or the like.

[0055] Optionally, a sliding hole is provided on the housing 100 , and the control member 300 is located in the sliding hole and can slide along the extending direction of the sliding hole.

[0056] For example, Figure 1 As shown, in order to control the sliding direction of the control member 300 and improve its stability during sliding, a sliding hole can also be provided on the housing 100, and the control member 300 and the sliding hole can be matched. For example, when the cross section of the control member 300 is circular, the radial cross section of the corresponding sliding hole is also circular, and when the cross section of the control member 300 is square, the radial cross section of the corresponding sliding hole is also square, etc. Thereby, the assembly accuracy of the control member 300 and the housing 100 is further improved, and more stable sliding is achieved.

[0057] Another aspect of the embodiments of the present invention provides a circuit breaker, comprising any one of the above-mentioned connection terminals.

[0058] For example, the above-mentioned terminal block is set in a circuit breaker, and the wire 600 connected can be compressed by the second end 410 of the elastic member to fix the wire 600, so that the wire 600 and the wiring portion 200 can maintain a stable conductive state. The elastic member 400 can be directly unlocked by inserting the wire 600, so that it automatically compresses the wire 600, which can effectively simplify the operation of inserting the wire 600 into the terminal block in the circuit breaker.
