Description

Technical Field

[0001] This application relates to the field of low-voltage electrical technology, and more specifically, to a switch and power supply system. Background Technology

[0002] Switches, as fundamental components of power distribution and control, are widely used in power supply systems such as distribution cabinets. With the increasing number of electrical devices, the number of switches that need to be accommodated inside distribution cabinets is also increasing, placing higher demands on the miniaturization and high-density installation of switches.

[0003] Existing switches typically include multiple phase units, each with a wiring portion electrically connected to an internal contact assembly and exposed outside the housing. The wiring portion typically extends parallel to the extension direction of each phase unit, while the wiring direction (i.e., the operating direction of the fastener) is parallel to the arrangement direction of the multiple phase units. In other words, the fastener performs wiring operations along the arrangement direction of the phase units. However, this layout has a significant drawback: because the wiring direction of the wiring portion is parallel to the arrangement direction of the multiple phase units, the space required for wiring operations is precisely between adjacent phase units. When multiple phase units are closely arranged, the space between adjacent phase units is extremely limited, making it difficult to insert tools (such as screwdrivers) for wiring operations, resulting in low wiring efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a switch and power supply system that avoids interference between wiring operations of adjacent phase units by setting the wiring direction of the wiring part to be perpendicular to the arrangement direction of multiple phase units, making wiring more convenient and efficient.

[0005] The embodiments of this application are implemented as follows: A first aspect of this application provides a switch comprising a plurality of phase pole units. Each phase pole unit includes a housing, a contact assembly disposed within a cavity of the housing, and a wiring portion electrically connected to the contact assembly and exposed outside the housing cavity. The extending direction of the wiring portion is parallel to the arrangement direction of the plurality of phase pole units, and the wiring direction of the wiring portion is perpendicular to the arrangement direction of the plurality of phase pole units. By setting the wiring direction of the wiring portion perpendicular to the arrangement direction of the plurality of phase pole units, this switch avoids wiring interference between adjacent phase pole units, making wiring more convenient and efficient.

[0006] In one possible implementation, the end of the housing is recessed inward to form a receiving groove with an opening, the wiring portion is received in the receiving groove, and the wire extends through the opening into the receiving groove to be electrically connected to the wiring portion.

[0007] In one possible implementation, a notch is provided on the housing corresponding to the wiring portion. The notch penetrates the wall of the receiving groove, and a fastener extends into the receiving groove through the notch so that the wire is electrically connected to the wiring portion through the fastener. The wiring direction of the wiring portion is the connection direction from the notch to the wiring portion.

[0008] In one possible implementation, the wiring portion is provided with a wiring hole, the wire is provided with a connection hole, the fastener passes through the connection hole and extends into the wiring hole, so that the head of the fastener presses the wire onto the wiring portion, and the orthographic projection of the notch on the wiring portion covers the orthographic projection of the head of the fastener on the wiring portion.

[0009] As one possible implementation, each phase pole unit further includes a contact connection portion exposed outside the housing cavity, the wiring portion being electrically connected to the contact assembly through the contact connection portion, and the extending direction of the contact connection portion, the extending direction of the wiring portion, and the wiring direction of the wiring portion being perpendicular to each other.

[0010] As one possible implementation, the wiring portion is located on one side of the contact connection portion along the extending direction of the contact connection portion.

[0011] In one possible implementation, the contact assembly includes a moving contact and a stationary contact that cooperates with the moving contact to open and close the circuit. The number of the wiring portions is two, and the two wiring portions are electrically connected to the moving contact and the stationary contact, respectively. The two wiring portions are disposed at both ends of the phase pole unit along the extension direction of the phase pole unit.

[0012] As one possible implementation, it also includes an operating handle. The extension direction of the phase pole unit is parallel to the height direction of the switch, the arrangement direction of the plurality of phase pole units is parallel to the length direction of the switch, the rotation axis of the operating handle is parallel to the width direction of the switch, and the operating handle is located on one side of the plurality of phase pole units along the length direction of the switch and is drively connected to the plurality of phase pole units to drive the contact assemblies of the plurality of phase pole units to open and close synchronously.

[0013] A second aspect of this application provides a power supply system including a distribution cabinet and the aforementioned switches. The distribution cabinet includes a cabinet body and multiple wires disposed within the cabinet body. The wiring portions of the multiple switches are electrically connected to the multiple wires in a one-to-one correspondence. When the switches are installed in the distribution cabinet, the extension direction of the phase pole unit is consistent with the height direction of the cabinet body, the extension direction of the wiring portion is consistent with the depth direction of the cabinet body, and the wiring direction of the wiring portion is consistent with the width direction of the cabinet body. The multiple switches are arranged along the width direction of the cabinet body. By setting the wiring direction of the wiring portion of the switch to be perpendicular to the arrangement direction of the multiple phase pole units, interference in wiring operations between adjacent phase pole units is avoided, making wiring more convenient and efficient.

[0014] As one possible implementation, when the switch further includes an operating handle, the rotation axis of the operating handle is aligned with the width direction of the cabinet, and the operating handle is driven to rotate around the rotation axis so that the operating end of the operating handle swings to an upper or lower position in the height direction of the cabinet.

[0015] The beneficial effects of the embodiments of this application include: This application sets the wiring direction of the wiring section to be perpendicular to the arrangement direction of multiple phase pole units, thereby shifting the wiring operation space to the outside of the arrangement direction of multiple phase pole units, avoiding interference between the operating tools and adjacent phase pole units. In this way, multiple phase pole units can be closely arranged along the arrangement direction without reserving extra space for wiring operations, providing a structural basis for high-density installation of switches in the distribution cabinet.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] Please refer to the reference. Figures 1 to 5 This application provides a switch 100, which includes a plurality of phase pole units 10. Each phase pole unit 10 includes a housing 11, a contact assembly disposed in the cavity of the housing 11, and a wiring portion 14 electrically connected to the contact assembly and exposed outside the cavity of the housing 11. The extension direction x of the wiring portion is parallel to the arrangement direction of the plurality of phase pole units 10, and the wiring direction y of the wiring portion is perpendicular to the arrangement direction of the plurality of phase pole units 10.

[0023] It should be noted that multiple phase pole units 10 are arranged side by side along the arrangement direction, and each phase pole unit 10 constitutes an electrode path of the switch 100. Each phase pole unit 10 is an independent unit box, and the phase pole units 10 can be assembled into a multi-pole switch 100 by side-by-side combination. Since each phase pole unit 10 integrates a housing 11, a contact assembly, and a wiring part 14, the assembly and testing of a single phase pole unit 10 can be completed in advance, and then the required number of phase pole units 10 can be combined side by side. Compared with the traditional integral housing 11 structure, this simplifies the assembly process and improves production efficiency and product yield. The wiring part 14, as an intermediate conductive component connecting the external wires and the internal contact assembly, extends in a direction parallel to the arrangement direction of the multiple phase pole units 10, so that the projection of the wiring part 14 in the arrangement direction of the multiple phase pole units 10 falls within the housing 11 of the multiple phase pole units 10, which is beneficial for the compact arrangement of the multiple phase pole units 10 and the overall miniaturization. The wiring direction y (i.e. the direction in which the fastener tightens the wire) of the wiring part is set to be perpendicular to the arrangement direction of the multiple phase pole units 10. Compared with the prior art where the wiring direction of the wiring part is parallel to the arrangement direction of the multiple phase pole units 10, this application transfers the wiring operation space to the outside that is perpendicular to the arrangement direction of the multiple phase pole units 10, thereby avoiding interference between the tool and adjacent phase pole units 10 during wiring operations. The wiring tool has sufficient operating space, and wiring is convenient and efficient.

[0024] As one possible implementation method, such as Figures 1 to 3 As shown, the end of the housing 11 is recessed inward to form a receiving groove 111 with an opening. The wiring part 14 is received in the receiving groove 111, and the wire extends into the receiving groove 111 through the opening and is electrically connected to the wiring part 14.

[0025] It should be noted that, along the extension direction of the phase unit 10, the receiving groove 111 is formed at the end of the housing 11, with its opening facing the outside of the housing 11. The wiring portion 14 is fixed inside the receiving groove 111 and does not protrude from the outer surface of the housing 11 (i.e., the projection of the wiring portion 14 on the housing 11 falls within the outer contour range of the housing 11), making full use of the internal space at the end of the housing 11, making the overall shape of the switch 100 more regular and compact, facilitating the high-density arrangement of multiple switches 100 in the distribution cabinet. The wire extends from the outside of the housing 11 through the opening into the receiving groove 111 and forms an electrical connection with the wiring portion 14. The receiving groove 111 provides clear guidance and limiting for the wire insertion, ensuring accurate and reliable contact between the wire and the wiring portion 14, while also providing physical protection for the wiring portion 14 to prevent accidental contact by external objects that could cause a short circuit or electric shock.

[0026] As one possible implementation method, such as Figures 1 to 3As shown, a notch 112 is provided on the housing 11 corresponding to the wiring part 14. The notch 112 penetrates the groove wall of the receiving groove 111. The fastener extends into the receiving groove 111 through the notch 112 so that the wire is electrically connected to the wiring part 14 through the fastener. The wiring direction y of the wiring part is the connection direction from the notch 112 to the wiring part 14.

[0027] The plane in which the wiring part 14 mates with the fastener is parallel to the plane formed by the arrangement direction of the multiple phase pole units 10 (i.e., the extension direction x of the wiring part) and the extension direction of the phase pole units 10 (i.e., the extension direction z of the contact connection part).

[0028] It should be noted that the notch 112 is formed in the wall of the receiving groove 111 and communicates with the interior of the receiving groove 111, forming a channel for the fastener to pass through. The fastener (such as a screw or bolt) extends into the receiving groove 111 through the notch 112, crimping or locking the wire to the terminal 14, thus achieving a reliable electrical connection between the wire and the terminal 14. The direction of the line connecting the notch 112 to the terminal 14 is the operating direction of the fastener, which is the wiring direction y of the terminal. Since the notch 112 is set in the wall of the receiving groove 111, its position determines the direction from which the fastener is inserted. Therefore, by setting the position of the notch 112, the wiring direction y of the terminal can be limited to a direction perpendicular to the arrangement direction of the multiple phase pole units 10. This structural design achieves precise guidance of the fastener's operating direction with a simple slotting method, without the need for additional guide parts, and is simple in structure and low in cost.

[0029] As one possible implementation method, such as Figures 1 to 3 As shown, the wiring part 14 is provided with a wiring hole, the wire is provided with a connection hole, the fastener passes through the connection hole and extends into the wiring hole, so that the head of the fastener presses the wire onto the wiring part 14, and the orthographic projection of the notch 112 on the wiring part 14 covers the orthographic projection of the head of the fastener on the wiring part 14.

[0030] It should be noted that the wiring hole is located on the wiring portion 14, and the connection hole is located at the end of the wire. The fastener passes through the connection hole of the wire and the wiring hole of the wiring portion 14 in sequence. The head of the fastener presses against the upper surface of the wire, pressing the wire tightly against the wiring portion 14, thereby achieving an electrical connection between the wire and the wiring portion 14. The orthographic projection of the notch 112 on the wiring portion 14 covers the orthographic projection of the fastener head on the wiring portion 14. This means that, viewed from the operating direction of the fastener, the opening range of the notch 112 is sufficient to accommodate the head of the fastener and the operating tool (such as a screwdriver head) to pass through completely. The notch 112 will not be too small, preventing the fastener from being unable to extend vertically or the operating tool from interfering with the housing 11. This limitation ensures that even within the limited space of the receiving slot 111, the operating tool can still smoothly operate the fastener at an angle perpendicular to the arrangement direction of the multiple phase pole units 10, further ensuring the operability of the core layout where the wiring direction y of the wiring portion is perpendicular to the arrangement direction of the multiple phase pole units 10 in actual assembly.

[0031] As one possible implementation method, such as Figures 1 to 5 As shown, each phase pole unit 10 also includes a contact connection portion 15 exposed outside the housing 11. The wiring portion 14 is electrically connected to the contact assembly through the contact connection portion 15. The extension direction z of the contact connection portion, the extension direction x of the wiring portion, and the wiring direction y of the wiring portion are perpendicular to each other.

[0032] It should be noted that the housing 11 has a cavity, the contact assembly is located inside the cavity, and the contact connection portion 15 is an intermediate conductive member located outside the cavity of the housing 11, connecting the wiring portion 14 and the internal contact assembly. The wiring portion 14 is electrically connected to the contact assembly through the contact connection portion 15. The extension direction z of the contact connection portion is configured to be perpendicular to both the extension direction x of the wiring portion (i.e., the arrangement direction of the multiple phase pole units 10) and the wiring direction y of the wiring portion (i.e., the operating direction of the fastener). In other words, the wiring portion 14 extends along the arrangement direction of the multiple phase pole units 10, the wiring operation is performed in a direction perpendicular to the arrangement direction of the multiple phase pole units 10, and the contact connection portion 15 extends along a third orthogonal direction, the three together forming a pairwise perpendicular relationship in three-dimensional space. The contact connection portion 15 serves as a transition section for direction conversion, allowing the wiring portion 14 to bend the current path and introduce it into the contact assembly inside the housing 11 while maintaining its extension along the arrangement direction of the multiple phase pole units 10, thereby adapting to the actual arrangement position of the contact assembly within the housing 11. Through this transitional structure, the external wiring layout of switch 100 (the extension direction x of the wiring part and the wiring direction y of the wiring part) and the arrangement of the internal contact assembly are no longer mutually constrained and can be designed independently, providing greater design freedom for the overall structural optimization of switch 100.

[0033] As one possible implementation method, such as Figures 3 to 5As shown, along the extending direction z of the contact connection portion, the wiring portion 14 is located on one side of the contact connection portion 15.

[0034] It should be noted that the wiring portion 14 is not connected to the end of the contact connection portion 15 along its extension direction, but is located on one side of the contact connection portion 15 along its extension direction. This side-mounted structure allows the arrangement of the wiring portion 14 to be adjusted according to the actual needs of the external wiring space. For example, the wiring portion 14 can be located closer to the operating handle 20, that is, the wiring portion 14 is located on one side of the contact connection portion 15 along its extension direction and extends towards the operating handle 20, in order to avoid other components or adapt to specific wiring paths. The side-mounted arrangement further improves the flexibility of the wiring portion 14's position layout, enabling the switch 100 to adapt to different installation environments and wiring habits.

[0035] As one possible implementation method, such as Figures 1 to 3 As shown, the contact assembly includes a moving contact and a stationary contact 13 that cooperates with the moving contact to open and close the circuit. There are two wiring portions 14, which are electrically connected to the moving contact and the stationary contact 13 respectively. The two wiring portions 14 are arranged at both ends of the phase pole unit 10 along the extension direction of the phase pole unit 10.

[0036] It should be noted that each phase unit 10 is provided with two wiring portions 14, which are respectively connected to the moving contact and the stationary contact 13, forming the input and output terminals of the phase unit 10. External wires are connected to the two wiring portions 14 respectively. Current is introduced through one wiring portion 14, flows through the contact area of ​​the moving contact and the stationary contact 13, and is then led out from the other wiring portion 14, forming a complete current path. The two wiring portions 14 are respectively located at both ends of the phase unit 10 along its extension direction, so that the input and output positions are far apart, avoiding spatial congestion and confusion of the two sets of external wires. At the same time, the layout of the two ends also allows the input and output of each phase unit 10 to be connected from their respective ends when multiple phase units 10 are arranged side by side along the arrangement direction, without interference, and the wiring is clear and orderly.

[0037] As one possible implementation method, such as Figure 4 As shown, the stationary contact 13 has a U-shaped structure with the opening of the U facing the outside of the housing 11. The two folded arms of the U extend along the extension direction of the phase pole unit 10, wherein the folded arm on the side away from the operating handle 20 in the arrangement direction of the multiple phase pole units 10 is connected to the contact connection part 15.

[0038] As one possible implementation method, such as Figure 5As shown, the moving contact has an L-shaped terminal block 12 inside the housing 11. The long side of the L-shaped terminal block 12 extends along the extension direction of the phase pole unit 10, and the short side extends along the arrangement direction of the multiple phase pole units 10. The short side is connected to the contact connection part 15 so that the moving contact is arranged closer to the operating handle 20 in the arrangement direction of the multiple phase pole units 10.

[0039] As one possible implementation method, such as Figures 1 to 3 As shown, the switch 100 also includes an operating handle 20. The extension direction of the phase pole unit 10 is parallel to the height direction of the switch 100. The arrangement direction of the multiple phase pole units 10 is parallel to the length direction of the switch 100. The rotation axis of the operating handle 20 is parallel to the width direction of the switch 100. The operating handle 20 is located on one side of the multiple phase pole units 10 along the length direction of the switch 100 and is connected to the multiple phase pole units 10 in a transmission manner to drive the contact assemblies of the multiple phase pole units 10 to open and close synchronously.

[0040] It should be noted that the operating handle 20 is located on one side of the multiple phase pole units 10 along the length direction of the switch 100 (such as the front side of the switch 100). The rotation axis of the operating handle 20 extends along the width direction of the switch 100. When the operating handle 20 is driven to rotate around the rotation axis, the rotational motion is transmitted to the contact assembly inside each phase pole unit 10 through the transmission mechanism (such as a rotating shaft, connecting rod or actuating element), driving the moving contact and stationary contact 13 of each phase pole unit 10 to close or separate synchronously, thereby realizing the closing or opening operation of the switch 100.

[0041] The rotation axis of the operating handle 20 extends along the width direction of the switch 100, and the operating handle 20 swings along the height direction of the switch 100. The transmission mechanism is arranged along the length direction of the switch 100 (i.e., the depth direction of the cabinet). Since the arrangement direction of the transmission mechanism is perpendicular to the width direction of the switch 100, the transmission structure no longer occupies space in the width direction of the switch 100. The overall width of the switch 100 is determined only by the width dimension of a single phase unit 10, effectively reducing the overall size of the switch 100 in the width direction. A larger number of switches 100 can be accommodated in a distribution cabinet of the same width, improving the circuit density and space utilization of the distribution cabinet.

[0042] Furthermore, since the operating handle 20 is located on one side of the multiple phase units 10 along the length of the cabinet, and the wiring direction y of the wiring section is perpendicular to the arrangement direction of the multiple phase units 10 (i.e., the width direction of the switch 100), the position of the operating handle 20 and the wiring operation direction are spatially offset from each other. The rotation operation of the operating handle 20 and the wiring operation of the wiring section 14 do not interfere with each other, and both can be performed independently and smoothly. This layout separates the operating surface and the wiring surface of the switch 100, making the operating interface clear, easy for users to identify and operate, and reducing the risk of misoperation.

[0043] This application embodiment also provides a power supply system, including a distribution cabinet and the aforementioned switch 100. The distribution cabinet includes a cabinet body and multiple wires disposed within the cabinet body. The wiring portions 14 of the multiple switches 100 are electrically connected to the multiple wires one-to-one. When the switches 100 are installed in the distribution cabinet, the extension direction of the phase unit 10 is consistent with the height direction of the cabinet body, the extension direction x of the wiring portion is consistent with the depth direction of the cabinet body, the wiring direction y of the wiring portion is consistent with the width direction of the cabinet body, and the multiple switches 100 are arranged along the width direction of the cabinet body.

[0044] It should be noted that in the actual installation scenario of the distribution cabinet, the placement orientation of the switch 100 is configured as follows: the extension direction of each phase unit 10 is along the height direction of the cabinet (i.e., the vertical direction), the extension direction x of the wiring part is along the depth direction of the cabinet (i.e., the front-to-back direction), and the wiring direction y of the wiring part (i.e., the fastener operation direction) is along the width direction of the cabinet (i.e., the left-to-right direction). Multiple switches 100 are arranged side by side along the width direction of the cabinet.

[0045] Since the wiring direction y of the wiring section is along the width of the cabinet, while the multiple phase units 10 inside each switch 100 are arranged along the depth of the cabinet, the wiring direction y of the wiring section is perpendicular to the arrangement direction of the multiple phase units 10. The wiring operation space for each phase unit 10 is located outside each phase unit 10 along the width of the cabinet, rather than the wiring direction being parallel to the arrangement direction of the multiple phase units 10. When an operator performs a wiring operation on a certain phase unit 10, the tool extends into the cabinet from the side along the width of the cabinet, and the operation space corresponds to the side area of ​​that phase unit 10 along the width of the cabinet. Adjacent phase units 10 are arranged in the depth direction of the cabinet and do not obstruct the wiring operation. The arrangement direction of multiple phase pole units 10 is consistent with the extension direction x of the wiring part. The wiring part 14 extends along the depth direction of the cabinet. The wires are connected from the upper and lower positions in the height direction of the cabinet, respectively. They are spatially orthogonal to the wiring operation direction. The operation space and the wiring space do not overlap. At the same time, they are staggered with the swing path of the operating handle 20 in the depth direction of the cabinet and do not interfere with each other.

[0046] As one possible implementation, when the switch 100 also includes an operating handle 20, the rotation axis of the operating handle 20 is aligned with the width direction of the cabinet, and the operating handle 20 is driven to rotate around the rotation axis so that the operating end of the operating handle 20 swings to the upper or lower position in the height direction of the cabinet.

[0047] It should be noted that the rotation axis of the operating handle 20 extends along the width of the cabinet, and the operating end of the operating handle 20 (i.e., the free end or gripping part of the operating handle 20) swings along the height of the cabinet when driven to rotate. When the operating end swings to the upper position, the switch 100 is in one working state (e.g., the closed state), and when the operating end swings to the lower position, the switch 100 is in another working state (e.g., the open state), or vice versa. The swing direction of the operating handle 20 is consistent with the extension direction of the phase pole unit 10, making full use of the vertical space in the height direction of the cabinet and avoiding additional space occupied in the width or depth direction of the cabinet when the operating handle 20 swings. At the same time, since the operating handle 20 is located on one side of the multiple phase pole units 10 along the length direction of the switch 100, the operator can see the actual position and swing state of the operating handle 20 from the front of the cabinet, which makes it easy to intuitively judge the on / off state of the switch 100, making the operation convenient and safe.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
