[0037] In the related art, the opening coil is installed on the mounting part of the circuit breaker by means of multiple screws. However, when the opening coil fails, it is necessary to use disassembly tools such as screwdrivers to replace the opening coil, which makes the disassembly and installation process of the opening coil time-consuming and labor-intensive, thereby affecting the replacement efficiency of the opening coil.

[0038] In addition, a circuit breaker is usually only provided with a single trip coil. When the trip coil fails and needs to be replaced, a large-scale power outage will occur. In severe cases, a long-term power outage may occur, causing trouble to users' daily lives.

[0039] In order to solve the above technical problems, in a first aspect, an embodiment of the present application provides a tripping assembly, which relates to the technical field of circuit breakers and is mainly used in circuit breakers.

[0040] like Figure 1 and Figure 2 As shown, the opening switch assembly 100 provided in this embodiment includes: an opening switch coil 110 , a mounting member 130 and an elastic pressing member 150 .

[0041] The opening coil 110 is provided with a first hooking portion 120, the mounting member 130 is provided with a second hooking portion 140 adapted to the first hooking portion 120, and the elastic pressing member 150 is provided on the mounting member 130. The first hooking portion 120 is hooked with the second hooking portion 140, and the elastic pressing member 150 presses against the opening coil 110, so that the opening coil 110 is detachably connected to the mounting member 130.

[0042] In the opening brake assembly 100 provided in this embodiment, since the opening brake coil 110 is provided with a first hooking portion 120, the mounting member 130 is provided with a second hooking portion 140 adapted to the first hooking portion 120, and the elastic pressing member 150 is provided on the mounting member 130. In this way, when the opening brake coil 110 is disassembled, the opening brake coil 110 is first pushed to overcome the elastic force applied by the elastic pressing member 150 on the opening brake coil 110 until the first hooking portion 120 is separated from the limit of the second hooking portion 140. When the opening brake coil 110 is installed, the opening brake coil 110 is pressed against the elastic pressing member 150, and the first hooking portion 120 is hooked on the second hooking portion 140, so that the opening brake coil 110 is in a locked state by relying on the elastic force of the elastic pressing member 150.

[0043] It can be understood that, since no disassembly tools are required during the disassembly and installation of the opening coil 110 , the replacement efficiency of the opening coil 110 is improved.

[0044] like Figure 3 and Figure 5 As shown, in one embodiment, the first hooking portion 120 is a hook, and the second hooking portion 140 is a hanging hole.

[0045] In this embodiment, since a hook is provided on the opening coil 110 and a matching hanging hole is provided on the mounting member 130, the hook can be hooked on the hanging hole to facilitate the installation and removal of the opening coil 110, thereby facilitating the replacement of the opening coil 110 when a fault occurs.

[0046] like Figure 2 and Figure 5 As shown, further, the hook includes a first hook section 121 and a second hook section 122, one end of the first hook section 121 is connected to the opening coil 110, and the part of the first hook section 121 away from the opening coil 110 is used to be inserted into the hanging hole, and the second hook section 122 is located on the side of the mounting member 130 away from the opening coil 110, and is connected to the end of the first hook section 121 away from the opening coil 110.

[0047] In this embodiment, by hooking the hook having the first hook section 121 and the second hook section 122 to the hanging hole, a better limiting effect can be achieved, limiting the opening coil 110 from being separated from the mounting member 130, thereby improving the stability of the opening coil 110 when it is stuck on the mounting member 130.

[0048] like Figure 2 and Figure 3 As shown, further, a plurality of hanging holes are provided, and two adjacent hanging holes are arranged at intervals, and a plurality of hooks are provided, each hook is used to hook at a hanging hole, and a part of the plurality of hanging holes penetrates the side of the mounting member 130 close to the elastic pressing member 150.

[0049] For example, there are four hanging holes, two of which penetrate the side of the mounting member 130 close to the elastic pressing member 150, and the other two hanging holes are located in the middle of the mounting member 130. Of course, the number of hanging holes can also be two, three, five, six, etc., which can be set according to design requirements and is not specifically limited here.

[0050] In this embodiment, by providing a plurality of hanging holes and a plurality of hooks, the stability of the opening coil 110 when it is stuck on the mounting member 130 can be improved. At the same time, since a portion of the plurality of hanging holes passes through the side of the mounting member 130 close to the elastic pressing member 150, the provision of this portion of the hanging holes facilitates the insertion of the hooks, thereby facilitating the installation of the opening coil 110 on the mounting member 130, thereby improving the replacement efficiency of the opening coil 110.

[0051] Of course, for the above embodiment, the first hook portion 120 can also be a hanging hole, and the second hook portion 140 can be a hook, which is also convenient for the installation and removal of the opening coil 110.

No specific restrictions are imposed on the structures of the connecting portion 151, the pressing portion 152, and the elastic portion 153.

[0054] It can be understood that the setting of the connecting portion 151 facilitates the installation of the elastic pressing member 150 on the mounting member 130, and the setting of the pressing portion 152 and the elastic portion 153, wherein the elastic portion 153 can provide elastic force, enables the pressing portion 152 to be elastically supported on the opening coil 110, thereby cooperating with the first hook portion 120 and the second hook portion 140 to put the opening coil 110 in a locked state.

[0055] like Figure 4As shown, further, the pressing portion 152 includes a straight segment 1521 and an arc segment 1522 , the straight segment 1521 is connected between the arc segment 1522 and the elastic portion 153 , and the arc segment 1522 is used to press on the opening coil 110 in a line contact manner.

[0056] In this embodiment, compared with the point contact method, the arc segment 1522 presses against the opening coil 110 through line contact, which can have a better pressing effect and improve the stability of the opening coil 110 when it is stuck on the mounting member 130.

[0057] like Figure 4 As shown, further, the opening switch assembly 100 also includes a threaded fastener 160 , the screw of the threaded fastener 160 is passed through the connecting portion 151 and the mounting member 130 , and is threadedly connected to the mounting member 130 .

[0058] For example, the threaded fastener 160 may be a screw, a bolt, a screw, or the like having a threaded rod.

[0059] In this embodiment, the elastic pressing member 150 is conveniently mounted on the mounting member 130 by means of the threaded fastener 160. When the elastic pressing member 150 fails, the threaded fastener 160 can be loosened and removed to replace the elastic pressing member 150.

[0060] Of course, for the above embodiment, the connecting portion 151 can also be a snap-fit, and a slot is provided on the mounting member 130 so that the elastic pressure member 150 can be snap-fitted to the slot through the snap-fit, which also facilitates the installation of the elastic pressure member 150 on the mounting member 130.

[0061] like Figure 3 As shown, in one embodiment, the mounting member 130 includes a first mounting plate 131, a second mounting plate 132 and a third mounting plate 133, the third mounting plate 133 is connected between the first mounting plate 131 and the second mounting plate 132, the elastic pressure member 150 is arranged on the third mounting plate 133, the first mounting plate 131, the second mounting plate 132 and the third mounting plate 133 jointly define a accommodating space 1331, and the opening coil 110 is arranged in the accommodating space 1331.
