Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electrical equipment, and in particular, to a switch. Background Art

[0002] A sampling structure is usually provided in the switch. One end of the sampling structure is connected to the main circuit of the switch, and the other end is connected to the controller. When an electrical signal abnormality occurs in the main circuit, the sampling structure transmits the abnormality to the controller, and the controller controls the switch to take corresponding actions to deal with the abnormal situation.

[0003] In the related art, the end of the sampling structure connected to the main circuit is the sampling terminal, and the end connected to the controller is the plug-in terminal. The sampling terminal and the plug-in terminal are connected by a wire. A hole is opened on the switch housing, and the wire passes through the hole. During assembly, in order to facilitate the wire to pass through the hole, the wire is only connected to the sampling terminal in advance. After the sampling terminal is connected to the main circuit, one end of the wire is passed through the hole and connected to the plug-in terminal outside the housing.

[0004] The assembly efficiency of the above switches is low, and there are certain differences in the assembly by personnel, making it difficult to ensure the quality of the switches. Utility Model Content

[0005] In view of the above problems, an embodiment of the present application provides a switch, which can improve the quality and assembly efficiency of the switch.

[0006] An embodiment of the present application provides a switch, the switch comprising a housing and a sampling structure;

[0007] The housing comprises a first housing and a second housing, the first housing and the second housing are buckled together to form a switch cavity, a first wiring groove is provided in the switch cavity, a second wiring groove is provided between the first housing and the second housing, and the first wiring groove and the second wiring groove are communicated;

[0008] The sampling structure includes a sampling terminal, a wire and a plug-in terminal connected in sequence. The sampling terminal is located in the switch cavity and connected to the main circuit of the switch. The plug-in terminal is used to connect to the controller. The wire is passed through the first wiring groove and the second wiring groove.

[0009] By setting the first wiring trough and the second wiring trough, it is convenient to load the wires from the notches of the first wiring trough and the second wiring trough, and to route the wires along the first wiring trough and the second wiring trough. Compared with the setting of accommodating the wires in the hole, the first wiring trough and the second wiring trough are more convenient for loading the wires, so that the sampling terminals, wires and plug-in terminals can be assembled in advance. When assembling the switch, before the first shell and the second shell are assembled, the wire part of the sampling structure is loaded into the first wiring trough and the second wiring trough, and then the first shell and the second shell are snapped together for assembly. It can be seen that after using the first wiring trough and the second wiring trough to replace the wiring hole, personnel do not need to manually assemble the sampling structure on site, but use the sampling structure that has been automatically assembled in advance. The quality consistency of the sampling structure is better, the reliability of the sampling signal is higher, and the assembly efficiency of the switch is also higher.

[0010] In some embodiments, the first wiring groove is provided with a notch, the notch faces into the switch cavity, and the width of the notch is smaller than the width of the groove.

[0011] By adopting the above solution, the notch is convenient for the wire to be inserted, and the notch of the first wiring groove faces the switch cavity, so that the wire can be inserted into the first wiring groove in the switch cavity, preventing the wire from being entangled with the components in the switch cavity. The width of the notch is smaller than the width of the groove, which can prevent the wire from escaping from the first wiring groove, making the first wiring groove more firmly fix the wire.

[0012] In some embodiments, a baffle is provided on one side of the first wiring groove facing the switch cavity, and the baffle is connected to one side in the width direction of the first wiring groove so that the width of the groove opening is smaller than the width inside the groove.

[0013] By adopting the above solution, the baffle can block a portion of one side in the width direction of the first wiring groove, so that the width dimension of the groove becomes smaller.

[0014] In some embodiments, the switch further includes a moving contact, the moving contact is located in the switch cavity, and the first wiring groove avoids an area directly facing the moving contact.

[0015] By adopting the above solution, the arc generated by the switch is prevented from directly entering the first wiring groove to burn the wire, and the temperature rise in the first wiring groove is reduced, thereby achieving the purpose of protecting the wire.

[0016] In some embodiments, the second wiring groove is located on the first shell, and a clearance groove is provided on the second shell, the clearance groove is connected to the outside of the shell, and the clearance groove and the second wiring groove are at least partially arranged opposite to each other; the clearance groove has a first opening and a second opening, the first opening faces the second wiring groove, and the second opening faces the outside of the shell.

[0017] By adopting the above solution, when the wire passes through the housing along the second wire routing groove, the wire can be located in either the second wire routing groove or the clearance groove, thereby increasing the space for accommodating the wire and preventing the wire from being squeezed, deformed or damaged. The first opening is used to communicate with the second wire routing groove, facilitating the wire to enter the clearance groove from the second wire routing groove, and the second opening facilitates the wire to extend from the clearance groove.

[0018] In some embodiments, a wall of the clearance groove away from the second opening is configured as an inclined surface, and in a direction away from the second wiring groove, the inclined surface is inclined toward a direction close to the second opening.

[0019] By adopting the above solution, when the wires are dispersedly extended from the clearance groove, each part of the inclined surface can support the wires from different positions of the wires, thereby preventing the wires from being bent in one direction under the action of gravity for a long time and causing tensile damage. In addition, the arrangement of the inclined surface makes the intersection angle between the groove wall on the side of the clearance groove away from the second opening and the surface of the second shell body close to the first shell body form an obtuse angle, thereby preventing the wires from being squeezed and damaged or even broken at the intersection angle.

[0020] In some embodiments, the wall of the clearance groove away from the second opening is configured as a curved surface, and the outer curved side of the curved surface faces the clearance groove.

[0021] By adopting the above solution, when the wires are dispersedly extended from the clearance groove, each part of the arc surface can support the wires from different positions of the wires, preventing the wires from being bent in one direction under the action of gravity for a long time and causing stretching damage. The outer arc side of the arc surface faces the clearance groove, so that the intersection angle between the groove wall on the side of the clearance groove away from the second opening and the surface of the second shell close to the first shell forms an obtuse angle, and the obtuse angle is relatively smooth, preventing the wires from being squeezed and damaged or even broken at the intersection angle.

[0022] In some embodiments, the switch further includes a stationary contact and a connector, both of which are disposed in the switch cavity. An assembly hole is disposed on the stationary contact, and the connector connects the sampling terminal and the stationary contact in the switch cavity.

[0023] By adopting the above solution, the connector can fix the static contact and the sampling terminal in the switch cavity at the same time, and can also simultaneously realize the connection between the sampling terminal and the static contact, so that the assembly of the switch is more convenient and the assembly efficiency is higher.

[0024] In some embodiments, there are M switch cavities, and there are N first wiring grooves, M≥N, each first wiring groove is arranged in a switch cavity, and the second wiring groove is connected to the N second wiring grooves.

[0025] By adopting the above solution, the wires passing through each first wiring groove can enter the same second wiring groove and pass through the housing from the second wiring groove. The wiring structure of the switch is simpler, saving the manufacturing cost of the switch.

[0026] The present application provides a first wiring groove and a second wiring groove so that the wires of the sampling structure can be loaded from the notches of the first wiring groove and the second wiring groove and routed along the first wiring groove and the second wiring groove. Instead of manually assembling the sampling structure on site, personnel use the sampling structure that has been automatically assembled in advance, which has better quality consistency of the sampling structure, higher reliability of the sampling signal, and higher assembly efficiency of the switch.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0036] The terms "comprising" and "having" and any variations thereof in the specification, claims and drawings of this application are intended to cover but not exclude other contents. The word "a" or "an" does not exclude the presence of a plurality.

[0037] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiments" in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0039] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the switch of the present application. For example, in the description of the present application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the figures, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application.

[0040] In addition, the expressions of the indicated directions such as the X direction, the Y direction and the Z direction used to illustrate the operation and construction of the components of the switch of this embodiment are not absolute but relative, and although these indications are appropriate when the components of the switch are in the positions shown in the figures, when these positions are changed, these directions should be interpreted differently to correspond to the changes.

[0041] In addition, the terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0042] In the description of the present application, unless otherwise specified, "plurality" means more than two (including two), and similarly, "multiple groups" means more than two groups (including two).

[0043] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, the "connection" or "connection" of a mechanical structure can refer to a physical connection. For example, the physical connection can be a fixed connection, such as a fixed connection through a fixing member, such as a fixed connection through a screw, bolt or other fixing member; the physical connection can also be a detachable connection, such as a mutual snap connection or snap connection; the physical connection can also be an integral connection, such as welding, bonding or integral molding to form a connection for connection. The "connection" or "connection" of a circuit structure can refer to not only a physical connection, but also an electrical connection or a signal connection. For example, it can be a direct connection, that is, a physical connection, or it can be indirectly connected through at least one intermediate element, as long as the circuit is connected, and it can also be the internal connection of two elements; in addition to signal connection through a circuit, a signal connection can also refer to signal connection through a media medium, such as a radio wave. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0044] In the related art, the end of the sampling structure connected to the main circuit is the sampling terminal, and the end connected to the controller is the plug-in terminal. The sampling terminal and the plug-in terminal are connected by a wire. A hole is opened on the shell of the switch, and the wire passes through the hole. During assembly, in order to facilitate the wire to pass through the hole, the wire is only connected to the sampling terminal in advance. After the personnel connect the sampling terminal to the main circuit, one end of the wire is passed through the hole and connected to the plug-in terminal outside the shell.

[0045] The switch assembled in the above manner has a high probability of having sampling errors or inaccurate signal transmission during use.

[0046] After research, the inventor found that this is because the connection between the plug-in terminal and the wire is manually assembled by assemblers. Due to the differences among assemblers, the connection consistency between the plug-in terminal and the wire is poor, which leads to a higher probability of quality problems in the switch.

[0047] If the wires and the plug terminals are assembled on the production line in advance and then installed on the switch housing, the opening on the housing needs to be larger, which is bound to be detrimental to the miniaturization of the switch and maintaining the structural strength.

[0048] In addition, since the wires need to pass through the openings on the housing and then be assembled with the plug-in terminals, the efficiency of switch assembly is low.

[0049] In order to solve the above-mentioned quality and efficiency problems in switch production, the embodiment of the present application provides a switch, such as Figure 1 , Figure 2 and Figure 3 As shown, the switch includes a housing 100 and a sampling structure 200 .

[0050] Among them, Figure 3 As shown, the shell 100 includes a first shell 110 and a second shell 120. The first shell 110 and the second shell 120 are buckled together to form a switch cavity 130. A first wiring groove 140 is provided in the switch cavity 130. A second wiring groove 150 is provided between the first shell 110 and the second shell 120. The first wiring groove 140 and the second wiring groove 150 are connected.

[0051] like Figure 2 As shown, the sampling structure 200 includes a sampling terminal 210, a wire 220 and a plug-in terminal 230 connected in sequence. The sampling terminal 210 is located in the switch cavity 130 and is connected to the main circuit of the switch. The plug-in terminal 230 is used to connect to the controller. The wire 220 is arranged in the first wiring groove 140 and the second wiring groove 150.

[0052] The sampling terminal 210 is connected to the main circuit of the switch and can collect electrical signals from the main circuit of the switch. The electrical signals may be information such as current and / or voltage. The information collected by the sampling terminal 210 is transmitted to the plug-in terminal 230 through the wire 220. The plug-in terminal 230 then transmits the telephone signal to the controller by connecting to the controller. The controller controls the execution unit of the switch to perform corresponding operations according to the electrical signal. For example, when the electrical signal increases abnormally, in order to prevent the circuit from burning, the controller can control the tripping mechanism of the switch to trip, thereby disconnecting the circuit in time and protecting the circuit.

[0053] The connection structure between the sampling terminal 210 and the plug-in terminal 230 and the wire 220 can be the same as that in the related art, and the connections can be assembled before being assembled to the housing 100. For example, before the assembly process of the circuit breaker, the sampling terminal 210, the wire 220 and the plug-in terminal 230 can be brought into the factory in an assembled state. In this way, the assembly consistency and structural stability of the sampling structure 200 are guaranteed. When it is used in a switch, the quality of the switch is improved and the assembly efficiency of the switch can be improved.

[0054] The switch cavity 130 is generally used to set the relevant components of the main circuit, such as the moving contact, the static contact 400, etc. Therefore, the sampling terminal 210 is generally connected in the switch cavity 130. The first wiring groove 140 is arranged in the switch cavity 130, so that the part of the wire 220 close to the sampling terminal 210 can directly enter the first wiring groove 140 and be routed along the wiring groove to prevent entanglement with other components in the switch cavity 130, and the first wiring groove 140 can protect the wire 220 and prevent the wire 220 from being burned by the arc.

[0055] The second wiring groove 150 is disposed between the first housing 110 and the second housing 120. It can be disposed on the first housing 110, or on the second housing 120, or partially on the first housing 110 and partially on the second housing 120. The embodiment of the present application does not limit this. The second wiring groove 150 is used to connect the first wiring groove 140 with the outside of the housing 100, so that the wire 220 can pass through the first wiring groove 140 and the second wiring groove 150 to connect the inside and the outside of the housing 100.

[0056] By providing the first wiring groove 140 and the second wiring groove 150, it is convenient to insert the wire 220 from the notches of the first wiring groove 140 and the second wiring groove 150, and the wire 220 is routed along the first wiring groove 140 and the second wiring groove 150. The wire 220 is arranged along a prescribed path in the housing 100, which is relatively neat and difficult to be entangled with other components.

[0057] Compared with the arrangement of accommodating the wire 220 in the hole, the first wiring groove 140 and the second wiring groove 150 are more convenient for loading the wire 220, so that the sampling terminal 210, the wire 220 and the plug terminal 230 can be assembled in advance. When assembling the switch, before assembling the first shell 110 and the second shell 120, the wire 220 part of the sampling structure 200 is loaded into the first wiring groove 140 and the second wiring groove 150, and then the first shell 110 and the second shell 120 are snap-fitted and assembled.

[0058] It can be seen that after using the first wiring groove 140 and the second wiring groove 150 to replace the wiring hole, personnel do not need to manually assemble the sampling structure 200 on site, but use the sampling structure 200 that has been automatically assembled in advance. The quality consistency of the sampling structure 200 is better, the reliability of the sampling signal is higher, and the assembly efficiency of the switch is also higher.

[0059] It can be understood that the wires 220 are arranged along the length direction of the first wiring trough 140 and the length direction of the second wiring trough 150 .

[0060] In some embodiments, the first wiring groove 140 is provided with a notch, the notch faces the inside of the switch cavity 130, and the width of the notch is smaller than the width of the inside of the groove.

[0061] The slot of the first wiring slot 140 refers to an opening of the first wiring slot 140 arranged along the length direction, and the width dimension of the slot refers to the dimension of the slot perpendicular to the slot direction and perpendicular to the length direction of the first wiring slot 140 .

[0062] The notch facilitates the insertion of the wire 220 . The notch of the first wiring groove 140 faces the switch cavity 130 , so that the wire 220 can be inserted into the first wiring groove 140 in the switch cavity 130 , preventing the wire 220 from being entangled with the components in the switch cavity 130 .

[0063] The width of the slot opening is smaller than the width of the slot, which can prevent the wire 220 from escaping from the first wiring slot 140 , so that the first wiring slot 140 fixes the wire 220 more firmly.

[0064] like Figure 3 As shown, in some embodiments, a baffle 300 is provided on one side of the first wiring groove 140 facing the switch cavity 130, and the baffle 300 is connected to one side of the first wiring groove 140 in the width direction so that the width of the groove is smaller than the width inside the groove.

[0065] The baffle 300 can block a portion of one side of the first wiring groove 140 in the width direction, so that the width of the groove becomes smaller.

[0066] Optionally, in some embodiments, the baffle 300 is integrally provided with the side wall of the notch, that is, the baffle 300 is processed when the first wiring groove 140 is processed on the side wall of the switch cavity 130 .

[0067] Optionally, in some embodiments, the baffle 300 is connected to a side wall on one side of the slot, and the connection method may be bonding, plugging, or snapping, etc., which is not limited in the embodiments of the present application.

[0068] In some embodiments, the switch further includes a moving contact, the moving contact is located in the switch cavity 130, and the first wiring groove 140 avoids the area directly facing the moving contact.

[0069] One end of the moving contact is fixed in the switch cavity 130, and the other end generally swings during the opening and closing of the switch. The moving contact facing area refers to the set of areas that one end of the moving contact faces during the swinging process.

[0070] The first wiring groove 140 avoids the area directly facing the moving contact, that is, the moving contact does not directly face the first wiring groove 140 at any time when it swings.

[0071] During the process of opening and closing the switch, an arc is generally generated, and the arc may spray toward the area directly facing the moving contact. The temperature of the arc is relatively high. If the wire 220 is within the movement range of the arc, it may be burned by the arc.

[0072] By avoiding the area directly facing the moving contact through the first wiring groove 140, the arc generated by the switch can be prevented from directly entering the first wiring groove 140 to burn the wire 220, and the temperature rise in the first wiring groove 140 can be reduced, thereby achieving the purpose of protecting the wire 220.

[0073] like Figure 1 and Figure 4 As shown, in some embodiments, the second wiring groove 150 is located on the first shell 110, and a clearance groove 160 is provided on the second shell 120, the clearance groove 160 is connected to the outside of the shell 100, and the clearance groove 160 and the second wiring groove 150 are at least partially arranged opposite to each other; the clearance groove 160 has a first opening 161 and a second opening 162, the first opening 161 faces the second wiring groove 150, and the second opening 162 faces the outside of the shell 100.

[0074] The clearance groove 160 is at least connected to the outside of the housing 100, so that the wire 220 extends from the clearance groove 160. The clearance groove 160 may or may not be connected to the inside of the housing 100, which is not limited in the embodiment of the present application.

[0075] The first opening 161 is used to communicate with the second wiring groove 150 to facilitate the wire 220 to enter the clearance groove 160 from the second wiring groove 150 , and the second opening 162 is convenient for the wire 220 to extend from the clearance groove 160 .

[0076] When the wire 220 passes through the housing 100 along the second wiring groove 150, the wire 220 can be located in the second wiring groove 150 or in the clearance groove 160, which increases the space for accommodating the wire 220 and prevents the wire 220 from being squeezed, deformed or damaged.

[0077] like Figure 4 As shown, in some embodiments, the wall of the clearance groove 160 away from the second opening 162 is set as an inclined surface, and in the direction away from the second wiring groove 150, the inclined surface is inclined toward the direction close to the second opening 162.

[0078] By adopting the above solution, when the wires 220 extend out of the clearance grooves 160 in a dispersed manner, the various parts of the inclined surface can support the wires 220 from different positions of the wires 220, thereby preventing the wires 220 from bending in one direction under the action of gravity for a long time and causing tensile damage.

[0079] In addition, the inclined surface makes the intersection angle between the groove wall of the clearance groove 160 away from the second opening 162 and the surface of the second shell 120 close to the first shell 110 form an obtuse angle, thereby preventing the wire 220 from being squeezed and damaged or even broken at the intersection angle.

[0080] In some embodiments, the wall of the clearance groove 160 away from the second opening 162 is configured as a curved surface, and the outer curved side of the curved surface faces the clearance groove 160 .

[0081] By adopting the above solution, when the wires 220 are dispersedly extended from the clearance groove 160, each part of the arc surface can support the wires 220 from different positions of the wires 220, preventing the wires 220 from bending in one direction under the action of gravity for a long time and causing tensile damage. The outer arc side of the arc surface faces the clearance groove 160, so that the intersection angle between the groove wall of the clearance groove 160 away from the second opening 162 and the surface of the second shell 120 close to the first shell 110 forms an obtuse angle, and the obtuse angle is relatively smooth, preventing the wires 220 from being squeezed and damaged or even broken at the intersection angle.

[0082] like Figure 3 As shown, in some embodiments, the switch further includes a stationary contact 400 and a connector 500 , both of which are disposed in the switch cavity 130 , and an assembly hole is disposed on the stationary contact 400 . The connector 500 connects the sampling terminal 210 and the stationary contact 400 in the switch cavity 130 .

[0083] The connecting member 500 can be a component such as a screw or a bolt. The bolt can pass through the assembly hole on the static contact 400 and the hole of the sampling terminal 210 in turn and be fixed in the switch cavity 130, so as to simultaneously fix the static contact 400 and the sampling terminal 210 in the switch cavity 130, and also simultaneously realize the connection between the sampling terminal 210 and the static contact 400, so that the assembly of the switch is more convenient and the assembly efficiency is higher.

[0084] In some embodiments, there are M switch cavities 130 , and N first wiring grooves 140 , where M≥N. Each first wiring groove 140 is disposed in a switch cavity 130 , and the second wiring groove 150 is connected to the N second wiring grooves 150 .

[0085] M≥N, that is, the first wiring groove 140 can be set in some switch cavities 130, the first wiring groove 140 can be not set in some switch cavities 130, or the first wiring groove 140 can be set in each switch cavity 130, depending on the sampling requirements of the switch, and the embodiment of the present application does not limit this.

[0086] For example, Figure 3 As shown, M=4, N=2, that is, the switch includes four switch cavities 130 and two first wiring grooves 140, the two first wiring grooves 140 are respectively located in two of the switch cavities 130, and the other two switch cavities 130 are not provided with first wiring grooves 140. When the sampling structure 200 is installed, the sampling terminal 210 can be connected only in the two switch cavities 130 provided with the first wiring grooves 140, and the other two switch cavities 130 are not provided with sampling terminals 210.

[0087] Since the second wiring groove 150 is connected to N second wiring grooves 150, the wire 220 passing through each first wiring groove 140 can enter the same second wiring groove 150 and pass through the shell 100 from the second wiring groove 150.
