In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0033] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0034] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In one aspect of the present invention, an auxiliary switch 300 contact is provided. Figure 1 , Figure 4 and Figure 6 The auxiliary switch trigger device 100 provided by the utility model includes a mounting member 110 and a push rod 120. The push rod 120 is movably arranged in the mounting member 110, and the mounting member 110 is detachably embedded in a notch 210 on a housing 200 of the disconnector. When the disconnector is closed, a transmission member 220 arranged in the housing 200 can push the push rod 120 along the extension direction of the push rod 120, so that one end of the push rod 120 away from the transmission member 220 is protruded from the edge of the mounting member 110 and abuts against the auxiliary switch 300, so as to transmit a closing signal to the auxiliary switch 300.

[0036] It should be noted that, first, Figure 1 and Figure 6 As shown, the auxiliary switch trigger device 100 includes a mounting member 110, which is a block-shaped structure and can be detachably embedded in the housing 200 of the isolating switch. Figure 8 As shown, the housing 200 is provided with a slot 210, and the mounting member 110 can slide along the extending direction of the slot 210 to achieve a detachable connection with the housing 200. The auxiliary switch trigger device 100 also includes a push rod 120, which is movably disposed in the mounting member 110.

[0037] The existing auxiliary switch trigger device is usually fixedly mounted on the housing of the isolating switch, so its mounting position is fixed. Therefore, in order to make the internal structure of the housing contact with the push rod, its mounting position is relatively limited, and the form of contact with the push rod is relatively simple. The mounting member 110 of the utility model is detachably embedded in the housing 200 of the isolating switch, which can not only flexibly adjust the positioning according to the internal structure of the housing 200, but also can be easily disassembled to replace the push rod 120 or other parts.

[0038] Optionally, the plane where the push rod 120 extends is perpendicular to the plate surface of the housing 200 where the mounting member 110 is located, or the extension direction of the push rod 120 is bent relative to the plate surface of the housing 200 where the mounting member 110 is located.

[0039] For example, Figure 1 As shown, in one possible implementation of the present application, the push rod 120 is a vertical structure, and the plane in which the push rod 120 extends is perpendicular to the plate surface of the housing 200 where the mounting member 110 is located; of course, in order to match the setting position of the transmission member 220 and improve the space utilization rate in the housing 200, the auxiliary switch trigger device 100 of the present invention can be disassembled and the push rod 120 can be adaptively replaced with a structure having a bent portion or other shapes, for example, Figure 7As shown, in another possible implementation of the present application, the extension direction of the push rod 120 is bent relative to the plate surface of the shell 200 where the mounting member 110 is located, so as to better match the setting position of the auxiliary switch 300 and the transmission member 220, thereby improving the flexibility of use.

[0040] Second, the push rod 120 is movably arranged in the mounting member 110. When the isolating switch is closed, the transmission member 220 arranged in the housing 200 can push or press the push rod 120 along the extension direction of the push rod 120. At this time, the end of the push rod 120 away from the transmission member 220 extends out of the mounting member 110 and can abut against the auxiliary switch 300 to transmit a closing signal to the auxiliary switch 300. When the isolating switch is opened, the transmission member 220 is separated from the end of the push rod 120. At this time, the push rod 120 is reset and no longer abuts against the auxiliary switch 300 to transmit an opening signal to the auxiliary switch 300. Through the cooperation process of the transmission member 220 and the push rod 120, the auxiliary switch 300 can reflect the opening state or the closing state of the isolating switch.

[0041] Third, if Figure 2 and Figure 5 As shown, the auxiliary switch trigger device 100 further includes an elastic member 130. The push rod 120 is a hollow structure. The elastic member 130 is installed in the hollow part 1211 of the push rod 120 along the movement direction of the push rod 120. The push rod 120 is pushed along the extension direction of the push rod 120. The elastic member 130 is subjected to force and stores energy, so that the end of the push rod 120 away from the transmission member 220 is protruded from the edge of the mounting member 110 and remains in contact with the auxiliary switch 300. When the isolating switch is opened, the transmission member 220 is separated from the end of the push rod 120. At this time, the elastic member 130 releases energy and drives the push rod 120 to reset. Preferably, the elastic member 130 can be a spring.

[0042] The utility model provides an auxiliary switch trigger device 100, comprising a mounting member 110 and a push rod 120, wherein the push rod 120 is movably arranged in the mounting member 110, and the mounting member 110 is detachably embedded in a notch 210 on a housing 200 of an isolating switch; when the isolating switch is closed, a transmission member 220 arranged in the housing 200 can push the push rod 120 along the extension direction of the push rod 120, so that one end of the push rod 120 away from the transmission member 220 is protruded on the edge of the mounting member 110 and abuts against the auxiliary switch 300 of the isolating switch, so as to transmit a closing signal to the auxiliary switch 300. The auxiliary switch trigger device 100 obtained by the above design is easy to disassemble, has a flexible setting position, is easy to replace internal parts, and has high flexibility.

[0043] For example, please refer to Figure 1The side wall of the mounting member 110 is provided with a slide groove 111 , the groove width of the slide groove 111 is adapted to the thickness of the housing 200 , and the mounting member 110 is slidably connected to the housing 200 through the slide groove 111 .

[0044] Specifically, the slide groove 111 is provided on the side wall of the mounting member 110, preferably, as Figure 1 and Figure 6 As shown, two opposite sides of the mounting member 110 are provided with slide grooves 111 to improve the disassembly and assembly efficiency of the auxiliary switch trigger device 100. The width of the slide groove 111 is adapted to the thickness of the housing 200, so that the mounting member 110 can be stably embedded in the housing 200 through the slide groove 111. The direction of the groove width is the same as the extension direction of the push rod 120. The provision of the slide groove 111 can make the connection between the mounting member 110 and the housing 200 more stable, and the disassembly and assembly process of the mounting member 110 is also more convenient.

[0045] It should be noted that if Figure 1 As shown, in one possible implementation of the present invention, the slide groove 111 is set through the mounting member 110. In another possible implementation of the present invention, the slide groove 111 can also be set in a form in which one end is connected to the outside and the other end is not connected to the outside, and the housing 200 is clamped with the mounting member 110 through the side of the slide groove 111 that is connected to the outside, and can slide along the slide groove 111.

[0046] For example, the mounting member 110 is provided with a first mounting groove 112 along the extension direction of the push rod 120 . The first mounting groove 112 is provided through the mounting member 110 , and the push rod 120 is movably provided in the first mounting groove 112 .

[0047] Specifically, Figure 3 As shown, the shape structure of the first mounting groove 112 is adapted to the shape structure of the push rod 120, so that the push rod 120 can be set in the first mounting groove 112; the first mounting groove 112 is set along the extension direction of the push rod 120 and is through-set on the mounting member 110, the push rod 120 can be driven to slide along the first mounting groove 112, and its end can extend out of the mounting member 110 through the first mounting groove 112 to abut against the auxiliary switch 300 to transmit a closing signal to the auxiliary switch 300.

[0048] Optionally, a limiting column 1121 is provided on the inner wall of the first mounting groove 112, and the push rod 120 includes a main body 121 and a limiting portion 122, the limiting portion 122 is arranged at one end of the main body 121 close to the auxiliary switch 300, and the width of the limiting portion 122 is greater than the width of the main body 121, and the direction of the width is perpendicular to the extension direction of the push rod 120; the main body 121 is arranged in the first mounting groove 112, and a side of the limiting portion 122 away from the auxiliary switch 300 can abut against the limiting column 1121.

[0049] For details, please continue to refer to Figure 3 A limiting column 1121 is provided on the inner wall of the first mounting groove 112, and the length of the limiting column 1121 is smaller than the groove width of the first mounting groove 112, wherein the length direction of the limiting column 1121 is perpendicular to the extension direction of the push rod 120, and the groove width direction of the first mounting groove 112 is in the same direction as the length direction of the limiting column 1121.

[0050] like Figure 2 and Figure 5 As shown, the push rod 120 includes a connected main body 121 and a limiting portion 122, the limiting portion 122 is arranged at one end of the main body 121 close to the auxiliary switch 300, the main body 121 is arranged in the first mounting groove 112 and is located on the side of the limiting column 1121 away from the auxiliary switch 300; the limiting portion 122 is arranged in the first mounting groove 112 and is located on the side of the limiting column 1121 close to the auxiliary switch 300, that is, the limiting column 1121 separates the main body 121 from the limiting portion 122.

[0051] The width of the limiting portion 122 is greater than the width of the main body 121, wherein the direction of the width is perpendicular to the extension direction of the push rod 120; this arrangement enables the side of the limiting portion 122 away from the auxiliary switch 300 to abut against the limiting column 1121. When the push rod 120 moves along the first mounting groove 112, the abutment between the limiting portion 122 and the limiting column 1121 can limit the movement range of the push rod, preventing the push rod 120 from detaching from the first mounting groove 112 and falling from the mounting member 110, thereby improving the stability of the setting of the push rod 120 and the mounting member 110.

[0052] For example, Figure 3 As shown, the mounting member 110 is provided with a second mounting groove 113 along the extension direction of the push rod 120 . The second mounting groove 113 is located in the middle of the first mounting groove 112 and is provided on opposite sides of the first mounting groove 112 to communicate with the first mounting groove 112 . The elastic member 130 is provided in the second mounting groove 113 .

[0053] Specifically, the middle of the first mounting groove 112 is provided with a second mounting groove 113, and the second mounting groove 113 is provided at two opposite sides of the first mounting groove 112 and is respectively connected to the first mounting groove 112. The elastic member 130 is sleeved in the middle of the push rod 120, the push rod 120 is provided in the first mounting groove 112, and the elastic member 130 is partially provided in the second mounting groove 113.

[0054] Please refer to Figure 2Since the second mounting groove 113 is arranged in the middle of the first mounting groove 112, the elastic member 130 is partially located in the second mounting groove 113 and can move in the second mounting groove 113. Therefore, when the push rod 120 is driven to move, the elastic member 130 is driven by the push rod 120 to move and is clamped at the connection between the second mounting groove 113 and the first mounting groove 112. At this time, the elastic member 130 is subjected to force and stores energy, so that the end of the push rod 120 extends out of the mounting member 110 and maintains contact with the auxiliary switch 300.

[0055] Furthermore, if Figure 3 and Figure 5 As shown, the width of the second mounting slot 113 away from the auxiliary switch 300 is smaller than the width of the second mounting slot 113 close to the auxiliary switch 300 , wherein the direction of the slot width is perpendicular to the extension direction of the push rod 120 .

[0056] With such a configuration, during the closing process of the disconnector, the push rod 120 moves along the first mounting groove 112, so that the movement range of the elastic member 130 is limited to the second mounting groove 113, and the elastic member 130 is pressed at the junction of the second mounting groove 113 and the first mounting groove 112 with the movement of the push rod 120, thereby storing energy. The second mounting groove 113 can limit the movement range of the elastic member 130, ensuring that the elastic member 130 cannot slide into the first mounting groove 112.

[0057] Preferably, the second mounting groove 113 is a triangular groove, such as Figure 3 and Figure 5 As shown, the second mounting groove 113 is a right triangle. Of course, in addition to the triangular groove, the second mounting groove 113 can also be a groove of other shapes and structures, such as a fan-shaped groove. The utility model does not impose any restrictions on the specific shape and structure of the second mounting groove 113, as long as the groove width of the second mounting groove 113 can be gradually reduced along the moving direction of the push rod 120 to limit the movement range of the elastic member 130.

[0058] Another aspect of the utility model provides an isolating switch, including a shell 200, a transmission member 220 and an auxiliary switch trigger device 100. The shell 200 is provided with a slot 210. The mounting member 110 of the auxiliary switch trigger device 100 is detachably inserted into the slot 210. A push rod 120 is movably arranged in the mounting member 110. The transmission member 220 is arranged in the shell 200. The transmission member 220 can push the push rod 120 along the extension direction of the push rod 120.

[0059] Specifically, the utility model also provides an isolating switch. The isolating switch includes a housing 200 and an auxiliary switch trigger device 100, wherein an auxiliary switch 300 is arranged in the housing 200; a notch 210 is provided on the housing 200, and the notch 210 has a certain depth, and a mounting member 110 of the auxiliary switch trigger device 100 can be inserted into the notch 210 and slide along the notch 210 to realize the disassembly of the auxiliary switch trigger device 100. A push rod 120 is movably arranged in the mounting member 110, and a transmission member 220 is arranged in the housing 200. When the isolating switch is closed, the transmission member 220 can push the push rod 120 along the extension direction of the push rod 120, so that one end of the push rod 120 protrudes from the edge of the mounting member 110 and abuts against the auxiliary switch 300, so as to transmit a closing signal to the auxiliary switch 300; when the isolating switch is opened, the transmission member 220 is separated from the end of the push rod 120, and at this time the push rod 120 is reset and no longer abuts against the auxiliary switch 300, so as to transmit an opening signal to the auxiliary switch 300.

[0060] Among them, Figure 4 and Figure 6 As shown, the auxiliary switch trigger device 100 is detachably arranged on the housing 200, so that its setting position can be more flexibly matched with the transmission member 220 in the housing 200 and the auxiliary switch 300 outside the housing 200, thereby making the structural position of each component in the housing 200 more flexible, reducing the limitation of the setting position of the internal structure of the housing 200, and improving the space utilization of the internal structure of the housing 200. Among them, the specific structure and beneficial effects of the auxiliary switch trigger device 100 have been described in detail above, and will not be repeated here.

[0061] The above description is only an optional embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0062] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
