Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a base assembly and a contactor. Background Art

[0002] Contactors are widely used switching devices with the advantages of strong current breaking capacity, rapid action, safe operation, frequent operation and remote control. Contactors are generally fixed in power distribution cabinets and connected to electrical equipment such as motors.

[0003] Due to technological development, the design of contactors tends to be miniaturized. After the size changes, in the process of replacing old products with new ones, a base assembly and a contactor are urgently needed to ensure the matching of the installation dimensions. Utility Model Content

[0004] The present application provides a base assembly and a contactor to increase the applicability of the contactor when it is installed on a cabinet.

[0005] In a first aspect, the present application provides a base assembly, including a base and a mounting seat, wherein the base is provided with a first mounting hole. The mounting seat is mounted on the base and partially exposed from the base, and the portion of the mounting seat exposed from the base is provided with an extended mounting hole. The first mounting hole is used for passing an end of a fastener through, or the extended mounting hole is used for passing an end of a fastener through, so as to fix the base to a power distribution cabinet.

[0006] Through the above scheme, the present application sets a first mounting hole and a mounting seat on the base, sets an extended mounting hole on the mounting seat, and can use fasteners to pass through the extended mounting hole to fix the base to the power distribution cabinet. Alternatively, the base can be fixed to the power distribution cabinet by passing through the first mounting hole with a fastener. In actual use, when installing the contactor in a new cabinet, the first mounting hole can be used for installation, and when replacing the old cabinet with a new contactor, the extended mounting hole can be used for installation, thus increasing the applicability of the contactor during installation.

[0007] In one possible design, the base is provided with a mounting groove, and the mounting seat includes a first part and a second part connected to each other, the first part is located in the mounting groove, and the second part can be exposed from the base, and the extended mounting hole is provided in the second part. The mounting seat can slide along the mounting groove to adjust the position of the extended mounting hole outside the base.

[0008] Through the above solution, the present application sets a mounting groove on the base, so that the first part of the mounting seat is slidably set in the mounting groove, so that the second part of the mounting seat can be exposed outside the base. By sliding the first part, the position of the second part outside the base can be adjusted, so that the position of the expanded mounting hole can be adjusted according to the position of the reserved hole of the power distribution cabinet, thereby increasing the application range of the base assembly.

[0009] In a possible design, the mounting groove includes a first groove and a second groove that are interconnected, and the mounting seat is mounted on the first groove, or the mounting seat is mounted on the second groove, and the first groove intersects with the second groove.

[0010] Through the above scheme, the intersecting first groove and the second groove are set in the installation groove, and the first groove and the second groove have a non-zero angle, which not only increases the setting range of the mounting seat, but also allows the setting position of the mounting seat to be flexibly selected according to the position of the reserved hole in the distribution cabinet, and the installation position of the mounting seat can be arbitrarily switched between the first groove and the second groove, thereby increasing the applicability of the base assembly, and the installation position of the mounting seat can be adjusted according to actual conditions at the installation site.

[0011] In one possible design, a limit member is provided on the groove wall of the installation groove, and a gap is provided between the limit member and the groove bottom of the installation groove. The first part is at least partially located in the gap. The limit member is used to limit the mounting seat in a first direction, and the first direction is consistent with the installation direction of the fastener.

[0012] Through the above scheme, a limit member is arranged in the installation groove, and a gap is left between the limit member and the bottom of the installation groove, so that part of the first part is arranged in the gap, and the limit member can be used to limit the mounting seat in the direction of the base being installed in the distribution cabinet. In this way, when the base is installed in the distribution cabinet, the problem of the mounting seat falling off from the base due to the lack of limit on the mounting seat is reduced, and the firmness of the base installed on the distribution cabinet is increased.

[0013] In a possible design, a convex rib is provided on the bottom wall of the installation groove, and one side of the first part in the first direction abuts against the limiting member, and the other side of the first part in the first direction abuts against the convex rib.

[0014] Through the above scheme, one side of the first part in the first direction is abutted against the limit groove, and the other side of the first part in the first direction is abutted against the convex rib. In this way, the first part can be clamped by using the limit member and the convex rib. In this way, not only the limiting effect of the limit member on the mounting seat is increased, but also the firmness of the mounting seat installed in the mounting groove can be increased, thereby increasing the firmness of the base when it is installed on the distribution cabinet.

[0015] In a possible design, the expanded mounting hole includes a first sub-hole and a second sub-hole, the first sub-hole and the second sub-hole are interconnected, and the first sub-hole and the second sub-hole have different specifications.

[0016] Through the above scheme, the expanded installation hole is set as the first sub-hole and the second sub-hole of different specifications, which can increase the application range of the mounting base. When the reserved hole on the distribution cabinet is larger, a fastener with a larger diameter is required, or when the reserved hole on the distribution cabinet is smaller, a fastener with a smaller diameter is required. At this time, the first sub-hole or the second sub-hole can be selected according to the specifications of the fastener.

[0017] In a possible design, the mounting seat can be retracted into the mounting groove until an end of the second part away from the first part is flush with the edge of the base.

[0018] Through the above scheme, the mounting seat can be slid in the mounting groove. When the base does not need to be installed in the distribution cabinet, the mounting seat can be retracted into the mounting groove until the second part is away from the end of the first part and is flush with the edge of the base. In this way, not only the aesthetics of the base can be increased, but also the mounting seat can be protected, reducing the problem of the mounting seat being easily damaged by bumps when it is exposed outside the base for a long time.

[0019] In a possible design, the first part includes a sliding portion and a connecting portion, one end of the connecting portion is connected to the sliding portion, the other end of the connecting portion is connected to the second part, and a non-zero angle is formed between the sliding portion and the connecting portion. The mounting groove includes a limiting wall, which can abut against the connecting portion to limit the range of movement of the mounting seat toward the outside of the mounting groove.

[0020] Through the above scheme, the first part is set as a connecting part and a sliding part, so that one end of the connecting part is connected to the sliding part, and the other end of the connecting part is connected to the second part, and there is a non-zero angle between the connecting part, the sliding part and the second part, so that the first part and the second part are in different planes. A limiting wall is set in the installation groove. When the sliding part slides in the installation groove, since the first part and the second part are in different planes, the limiting wall can limit the movement of the mounting seat, thereby reducing the possibility of the mounting seat falling from the installation groove and increasing the reliability of the base being installed in the power distribution cabinet.

[0021] In a possible design, the first part is provided with a second mounting hole, and when the mounting seat is located outside the base, the second mounting hole is opposite to the first mounting hole, and when the mounting seat is retracted into the mounting groove, the first mounting hole is opposite to the expanded mounting hole. The end of the fastener passes through the first mounting hole and the expanded mounting hole at the same time to fix the base to the power distribution cabinet.

[0022] Through the above solution, when the mounting seat is retracted along the mounting groove until the end of the second part away from the first part is flush with the edge of the base, the position of the first mounting hole corresponds to the position of the extended mounting hole. At this time, when installing the contactor, the fastener can pass through the first mounting hole and the extended mounting hole in sequence, and then enter the reserved hole of the power distribution cabinet to fix the base in the power distribution cabinet, that is, whether the second part is exposed outside the base, or the second part is retracted along the mounting groove into the base, it will not affect the installation of the base.

[0023] In a second aspect, the present application provides a contactor, comprising the base assembly provided in the first aspect.

[0024] Through the above scheme, the base assembly of the present application includes a base and a mounting seat, a first mounting hole is set on the base, and an extended mounting hole is set on the mounting seat. The base can be fixed to the power distribution cabinet by fasteners passing through the first mounting hole, or the base can be fixed to the power distribution cabinet by fasteners passing through the extended mounting hole. In this way, the applicability of the contactor during installation is increased. When installing the contactor in a new cabinet, the first mounting hole can be used for installation, and when replacing the old cabinet with a new contactor, the extended mounting hole can be used for installation.

[0025] The beneficial effects of the contactor provided in the second aspect can be referred to the beneficial effects brought about by the first aspect and the various possible implementation methods of the first aspect, which will not be described in detail here.

[0044] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0045] The present application provides a contactor, which includes a base assembly.

[0046] Contactors are widely used switching devices. They are usually installed in power distribution cabinets and connected to electrical equipment such as motors. Contactors are used to control circuits to switch the main circuit on and off.

[0047] The base assembly is provided with mounting holes. When the contactor needs to be installed in the power distribution cabinet, first, holes are punched on the power distribution cabinet, and the holes on the power distribution cabinet are aligned with the mounting holes set on the base assembly, and then the fasteners are passed through the mounting holes set on the base assembly and the holes on the power distribution cabinet in sequence to fix the contactor in the power distribution cabinet.

[0048] In the prior art, with the development of technology, the size of contactors is constantly getting smaller. When old users need to replace new models of contactors, the holes reserved for installing contactors on the original distribution cabinet will not be suitable for the new models of contactors. Re-drilling holes in the distribution cabinet is not only time-consuming and labor-intensive, but may also damage other electrical components in the distribution cabinet.

[0049] Based on this, the present application improves the structure of the base assembly to increase the applicability of the contactor when it is installed in the cabinet.

[0050] The base assembly provided in the present application is explained in detail below with reference to the accompanying drawings.

[0051] Figure 1 A schematic structural diagram of a base assembly provided in an embodiment of the present application in a certain state and from a certain viewing angle.

[0052] like Figure 1 As shown, the present application provides a base assembly, including a base 100 and a mounting base 200, wherein the base 100 is provided with a first mounting hole 120. The mounting base 200 is mounted on the base 100 and partially exposed from the base 100, and an extended mounting hole 210 is provided on the portion of the mounting base 200 exposed from the base 100. The first mounting hole 120 is used for the end of a fastener to pass through, or the extended mounting hole 210 is used for the end of a fastener to pass through, so as to fix the base 100 to the power distribution cabinet.

[0053] The base 100 is provided with an installation space inside, and some components of the contactor are installed in the installation space. The base 100 is provided with at least one first installation hole 120, which is a through hole so that a fastener can pass through the first installation hole 120, thereby fixing the base 100 to the power distribution cabinet. The fastener can be a bolt, a screw, a shaft pin, etc.

[0054] The mounting base 200 is provided with an extended mounting hole 210, which is a through hole. The extended mounting hole 210 can be circular or square, etc. The portion of the mounting base 200 provided with the extended mounting hole 210 is exposed from the base 100, so that the fastener can pass through the extended mounting hole 210, thereby fixing the base 100 to the power distribution cabinet.

[0055] There are two situations when the contactor needs to be installed in the power distribution cabinet. The following are examples of the two situations respectively.

[0056] The first case: first determine the location of the holes to be drilled on the cabinet of the power distribution cabinet according to the location of the first installation hole 120, then drill holes at the predetermined locations, and finally use fasteners to pass through the first installation hole 120 and the newly drilled holes on the power distribution cabinet in sequence to install the contactor on the power distribution cabinet. This case is applicable when the user is using a brand new power distribution cabinet.

[0057] In the first case, when the user installs a contactor for a new distribution cabinet, the contactor is installed on the distribution cabinet by using the fasteners in cooperation with the first mounting holes 120, thereby reducing the difficulty of subsequent replacement of the contactor. It is only necessary to align the new contactor with the reserved holes of the distribution cabinet for replacement and installation.

[0058] The second situation: first align the expanded installation hole 210 with the reserved hole position on the power distribution cabinet, and then use fasteners to pass through the expanded installation hole 210 and the original reserved hole on the power distribution cabinet in turn to install the contactor on the power distribution cabinet. This situation is suitable for: when the user replaces a small-volume contactor for the original power distribution cabinet.

[0059] In the second case, when the user replaces the original distribution cabinet with a small contactor, the small contactor can still be installed in the installation position originally reserved for the distribution cabinet, and there is no need to re-drill the distribution cabinet, which not only saves labor and time costs, but also reduces the problem of the drill bit causing damage to other electrical components in the distribution cabinet when drilling holes in the distribution cabinet.

[0060] In summary, the present application sets a first mounting hole 120 and a mounting seat 200 on the base 100, and sets an extended mounting hole 210 on the mounting seat 200, and the base 100 can be fixed to the power distribution cabinet by passing a fastener through the extended mounting hole 210. Alternatively, the base 100 can be fixed to the power distribution cabinet by passing a fastener through the first mounting hole 120. In actual use, when installing a contactor in a new cabinet, the first mounting hole 120 can be used for installation, and when replacing a new contactor in an old cabinet, the extended mounting hole 210 can be used for installation, thereby increasing the applicability of the contactor during installation.

[0061] Figure 2 A schematic structural diagram of a base 100 provided in an embodiment of the present application. Figure 3 Schematic diagram of the structure of the mounting base 200 provided in the embodiment of the present application. Figure 2 as well as Figure 3 As shown, the base 100 is provided with a mounting groove 110, and the mounting seat 200 includes a first part 220 and a second part 230 connected to each other, the first part 220 is located in the mounting groove 110, and the second part 230 is exposed from the base 100, and the extended mounting hole 210 is provided in the second part 230, and the mounting seat 200 can slide along the mounting groove 110 to adjust the position of the extended mounting hole 210 outside the base 100.

[0062] The mounting groove 110 is a groove formed on the base 100. The mounting groove 110 can be formed integrally with the base 100 when the base 100 is formed, or the mounting groove 110 can be provided on the base 100 by carving or drilling after the base 100 is formed.

[0063] The mounting base 200 includes a first portion 220 and a second portion 230 connected to each other, wherein the first portion 220 can be slidably disposed in the mounting groove 110, and the second portion 230 is provided with an expanded mounting hole 210, and the second portion 230 can be exposed from the base 100. By sliding the first portion 220 in the mounting groove 110, the position of the second portion 230 outside the base 100 can be adjusted.

[0064] The first part 220 and the second part 230 can be integrally formed. When this molding method is used, the manufacturing process of the mounting base 200 can be reduced. The first part 220 and the second part 230 can also be formed separately and then assembled. When this molding method is used, since the second part 230 is provided with an extended mounting hole 210, and the extended mounting hole 210 needs to cooperate with the fastener, the loss of the second part 230 is higher than that of the first part 220. At this time, when the loss of the second part 230 is too large, the second part 230 can be replaced separately, reducing the subsequent maintenance cost of the base assembly.

[0065] In summary, the present application sets a mounting groove 110 on the base 100, so that the first part 220 of the mounting seat 200 is slidably set in the mounting groove 110, so that the second part 230 of the mounting seat 200 can be exposed outside the base 100. By sliding the first part 220, the position of the second part 230 outside the base 100 can be adjusted, so that the position of the extended mounting hole 210 can be adjusted according to the position of the reserved hole of the power distribution cabinet, thereby increasing the application range of the base assembly.

[0066] Figure 4 This is a cross-sectional view of the base 100 provided in the embodiment of the present application. Figure 4 As shown, the mounting groove 110 includes a first groove 111 and a second groove 112 that are connected to each other, and the mounting seat 200 is mounted in the first groove 111 , or the mounting seat 200 is mounted in the second groove 112 , and the first groove 111 and the second groove 112 intersect.

[0067] The first groove 111 and the second groove 112 are grooves provided in the mounting groove 110. The first groove 111 and the second groove 112 can be integrally formed with the mounting groove 110 when the mounting groove 110 is formed, or the first groove 111 and the second groove 112 can be provided in the mounting groove 110 by carving or drilling after the mounting groove 110 is formed. There is a non-zero angle between the first groove 111 and the second groove 112, for example, the angle between the first groove 111 and the second groove 112 can be 30°, 45° or 90°.

[0068] The mounting seat 200 can be installed in the first groove 111, and the mounting seat 200 can also be installed in the second groove 112. Since the first groove 111 and the second groove 112 intersect, when the mounting seat 200 is installed in the first groove 111, the mounting seat 200 can also be switched from the first groove 111 to the second groove 112 by rotation or the like, or when the mounting seat 200 is installed in the second groove 112, the mounting seat 200 can be switched from the second groove 112 to the first groove 111 by rotation or the like.

[0069] Through the above-mentioned arrangement, the intersecting first groove 111 and the second groove 112 are arranged in the installation groove 110, and a non-zero angle is provided between the first groove 111 and the second groove 112, which not only increases the setting range of the mounting base 200, but also allows the setting position of the mounting base 200 to be flexibly selected according to the position of the reserved hole in the power distribution cabinet, and the installation position of the mounting base 200 can be arbitrarily switched between the first groove 111 and the second groove 112, thereby increasing the applicability of the base assembly, and the installation position of the mounting base 200 can be adjusted according to actual conditions at the installation site.

[0070] Figure 5 A schematic structural diagram of a base assembly provided in an embodiment of the present application in one state from another perspective.

[0071] like Figure 2 , Figure 4 as well as Figure 5 As shown, a groove wall of the mounting groove 110 is provided with a limit member 113, and a gap 114 is provided between the limit member 113 and the groove bottom of the mounting groove 110. The first portion 220 is at least partially located in the gap 114. The limit member 113 is used to limit the mounting seat 200 in the first direction OX, and the first direction OX is consistent with the installation direction of the fastener.

[0072] The limiting member 113 may be integrally formed with the mounting groove 110 when the mounting groove 110 is formed, or the limiting member 113 may be formed separately and then installed in the mounting groove 110 .

[0073] The gap 114 is the space between the limiting member 113 and the bottom of the mounting groove 110. Since the first portion 220 is at least partially located in the gap 114, and the limiting member 113 is used to limit the movement of the mounting seat 200, the size of the gap 114 can be determined according to the thickness of the first portion 220. The gap 114 can be the same as the thickness of the first portion 220, or the size of the gap 114 can be slightly larger than the thickness of the first portion 220.

[0074] The first direction OX is the direction in which the base 100 is installed in the power distribution cabinet.

[0075] To summarize, a limit member 113 is provided in the mounting groove 110, and a gap 114 is left between the limit member 113 and the bottom of the mounting groove 110, so that part of the first portion 220 is disposed in the gap 114, and the limit member 113 can be used to limit the mounting seat 200 in the direction in which the base 100 is installed in the power distribution cabinet. In this way, when the base 100 is installed in the power distribution cabinet, the problem of the mounting seat 200 falling off from the base 100 due to the lack of limit on the mounting seat 200 is reduced, thereby increasing the firmness of the base 100 installed on the power distribution cabinet.

[0076] Please continue to refer to Figure 2 as well as Figure 4 As shown, the bottom wall of the installation groove 110 is provided with a convex rib 115 , one side of the first part 220 in the first direction OX abuts against the limiter 113 , and the other side of the first part 220 in the first direction OX abuts against the convex rib 115 .

[0077] The rib 115 may be a short columnar structure or protrusion protruding from the bottom wall of the mounting groove 110. The rib 115 may be integrally formed with the mounting groove 110 when the mounting groove 110 is formed, or the rib 115 may be disposed in the mounting groove 110 after the mounting groove 110 is formed.

[0078] Through the above-mentioned arrangement, one side of the first part 220 in the first direction OX is abutted against the limiting groove, and the other side of the first part 220 in the first direction OX is abutted against the convex rib 115. In this way, the first part 220 can be clamped by using the limiting member 113 and the convex rib 115. In this way, not only the limiting effect of the limiting member 113 on the mounting base 200 is increased, but also the firmness of the mounting base 200 installed in the mounting groove 110 can be increased, thereby increasing the firmness of the base 100 when installed on the distribution cabinet.

[0079] like Figure 3 As shown, the expanded mounting hole 210 includes a first sub-hole 211 and a second sub-hole 212 . The first sub-hole 211 and the second sub-hole 212 are connected to each other, and the first sub-hole 211 and the second sub-hole 212 have different specifications.

[0080] The first sub-hole 211 may be circular or square, etc., and the second sub-hole 212 may also be circular or square, etc. The first sub-hole 211 and the second sub-hole 212 may be integrally formed with the second part 230 when the second part 230 is formed, or the first sub-hole 211 and the second sub-hole 212 may be provided on the second part 230 by carving or drilling after the second part 230 is formed.

[0081] The first sub-hole 211 and the second sub-hole 212 may be connected, or may not be connected.

[0082] The first sub-hole 211 and the second sub-hole 212 have different specifications, and the setting specifications of the first sub-hole 211 and the second sub-hole 212 can be selected according to the setting specifications of the fastener. For example, the fastener is a screw, for example: the fastener can be an M5 screw or an M6 screw, etc. At this time, the diameter of the first sub-hole 211 can be 5 mm, and the diameter of the second sub-hole 212 can be 6 mm.

[0083] Through the above-mentioned setting, the expanded mounting hole 210 is set as a first sub-hole 211 and a second sub-hole 212 of different specifications, so that the application range of the mounting base 200 can be increased. When the reserved hole on the distribution cabinet is larger, a fastener with a larger diameter is required, or when the reserved hole on the distribution cabinet is smaller, a fastener with a smaller diameter is required. At this time, the first sub-hole 211 or the second sub-hole 212 can be selected according to the specifications of the fastener.

[0084] Figure 6 This is a schematic diagram of the structure of the base assembly provided in an embodiment of the present application in another state. Figure 6 As shown, the mounting seat 200 can be retracted toward the mounting groove 110 until the end of the second portion 230 away from the first portion 220 is flush with the edge of the base 100 .

[0085] Through the above-mentioned arrangement, by utilizing the arrangement that the mounting base 200 can slide in the mounting groove 110, when the base 100 does not need to be installed in the power distribution cabinet, the mounting base 200 can be retracted into the mounting groove 110 until the end of the second part 230 away from the first part 220 is flush with the edge of the base 100. In this way, not only the aesthetics of the base 100 can be increased, but also the mounting base 200 can be protected, thereby reducing the problem of the mounting base 200 being easily damaged by bumps when the mounting base 200 is exposed outside the base 100 for a long time.

[0086] like Figures 1 to 3 As shown, the first part 220 includes a sliding part 221 and a connecting part 222, one end of the connecting part 222 is connected to the sliding part 221, and the other end of the connecting part 222 is connected to the second part 230, and there is a non-zero angle between the sliding part 221 and the connecting part 222. The mounting groove 110 includes a limiting wall 116, which can abut against the connecting part 222 to limit the range of movement of the mounting seat 200 toward the outside of the mounting groove 110.

[0087] The sliding part 221 and the connecting part 222 can be integrally formed, or they can be separately formed and then assembled. The sliding part 221 is in sliding contact with the bottom of the mounting groove 110, one end of the connecting part 222 is connected to the sliding part 221, and the other end of the connecting part 222 is connected to the second part 230. There is a non-zero angle between the sliding part 221 and the connecting part 222, and there is a non-zero angle between the sliding part 221 and the second part 230, so that the mounting seat 200 forms a Z-shaped structure in space.

[0088] The limiting wall 116 may be a groove wall of the mounting groove 110, or may be separately disposed in the mounting groove 110. The limiting wall 116 is located in the moving direction of the mounting seat 200 in the mounting groove 110. When the mounting seat 200 slides along the mounting groove 110, the limiting wall 116 may limit the movement of the mounting seat 200 by limiting the connection portion 222, thereby reducing the occurrence of the problem that the mounting seat 200 falls out of the mounting groove 110 due to factors such as excessive force.

[0089] In summary, the first part 220 is configured as a connecting part 222 and a sliding part 221, so that one end of the connecting part 222 is connected to the sliding part 221, and the other end of the connecting part 222 is connected to the second part 230, and there is a non-zero angle between the connecting part 222, the sliding part 221 and the second part 230, so that the first part 220 and the second part 230 are in different planes. A limiting wall 116 is provided in the mounting groove 110. When the sliding part 221 slides in the mounting groove 110, since the first part 220 and the second part 230 are in different planes, the limiting wall 116 can limit the movement of the mounting seat 200, thereby reducing the possibility of the mounting seat 200 falling from the mounting groove 110 and increasing the reliability of the base 100 installed in the power distribution cabinet.

[0090] In a possible design, the first portion 220 is provided with a second mounting hole 223. When the mounting seat 200 is located outside the base 100, the second mounting hole 223 is opposite to the first mounting hole 120. When the mounting seat 200 is retracted into the mounting slot 110, the first mounting hole 120 is opposite to the expanded mounting hole 210. The end of the fastener passes through the first mounting hole 120 and the expanded mounting hole 210 at the same time to fix the base 100 to the power distribution cabinet.

[0091] The second mounting hole 223 may be disposed on the sliding portion 221 . The second mounting hole 223 is a through hole. When the second portion 230 is exposed outside the base 100 , the second mounting hole 223 disposed on the sliding portion 221 is located opposite to the first mounting hole 120 .

[0092] Through the above arrangement, when the mounting base 200 is retracted along the mounting groove 110 until the end of the second part 230 away from the first part 220 is flush with the edge of the base 100, the position of the first mounting hole 120 corresponds to the position of the extended mounting hole 210. At this time, when installing the contactor, the fastener can pass through the first mounting hole 120 and the extended mounting hole 210 in sequence, and then enter the reserved hole of the power distribution cabinet to fix the base 100 in the power distribution cabinet, that is, whether the second part 230 is exposed outside the base 100, or the second part 230 is retracted along the mounting groove 110 into the base 100, it will not affect the installation of the base 100.

[0093] In a possible design, a chamfer is provided on a side of the limiting member 113 facing away from the groove bottom.

[0094] The chamfer may be a 45° chamfer, a rounded chamfer or a V-shaped chamfer, etc. The chamfer may be formed integrally with the stopper 113 when the stopper 113 is formed, or the chamfer may be provided by grinding or carving after the stopper 113 is installed in the installation slot 110 .

[0095] Through the above-mentioned arrangement, since the limit member 113 is arranged in the mounting groove 110, and the limit member 113 can limit the movement of the first part 220 in the first direction OX, this causes the mounting seat 200 to be subjected to certain resistance during the process of being installed into the mounting groove 110, and the chamfer arrangement can reduce the resistance generated by the limit member 113 on the mounting seat 200 during the process of installing the mounting seat 200 into the mounting groove 110, so that the mounting seat 200 can be more easily installed in the mounting groove 110, and the chamfer arrangement can also play a guiding role in the installation of the mounting seat 200.
