Description

[0002] Round tubes on the market (size: ) Each fuse has its own matching rail-type fuse holder, which is also the most widely used fuse holder on the market. For simple circuits, only a single fuse holder is needed to be used with the fuse core, and a microswitch signal is used to output instructions to the terminal. The circuit is simple. However, for complex circuits in the circuit, multiple rail fuse holders are required to be used with fuses, and the use of internal fuses needs to be fed back as soon as possible.

[0057] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0059] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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.

[0060] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0061] like Figures 1 to 8 A new energy multi-splice fuse holder signal device shown includes: two micro switches 22, which are arranged on one side of the multi-splice fuse 1 close to the fuse trigger mechanism 11, and the two micro switches 22 are connected in series through a connecting wire 24, one micro switch 22 is connected to the current input terminal 32, and the other micro switch 22 is connected to the current output terminal 31.

[0062] The operating lever 23 is disposed on a side of the micro switch 22 close to the fuse trigger mechanism 11 .

[0063] The micro switch fixing member 21 is fixedly connected to the multi-piece fuse 1 and is used to fix the micro switch 22 .

[0064] One side of the joystick 23 abuts against the multiple fuse triggering mechanisms 11 on the multiple fuses 1, and the fuse triggering mechanisms 11 are activated, pushing the joystick 23 to slide toward the side where the micro switch 22 is located, activating the micro switch 22 and sending an abnormal signal.

[0065] The number of micro switches 22 is reduced by providing the joystick 23, and the circuit structure is further simplified by connecting them in series.

[0066] The multi-connected fuse 1 comprises a plurality of fuse rail seats, each of which is provided with a fuse trigger mechanism 11 , and all the fuse trigger mechanisms 11 are located on the same side of the multi-connected fuse 1 .

[0067] In this embodiment, the number of micro switches 22 used is reduced by setting the joystick 23, and the number of circuits connected to the micro switches 22 is reduced. At the same time, the circuit structure is further simplified by connecting the micro switches 22 in series. When any of the multiple fuses sends a signal, the abnormal signal can be sent through only one line, which is relatively simple and convenient for maintenance.

[0068] like Figures 9 to 13 The micro switch 22 shown includes:

[0069] The housing 221 has an operation hole 2214 on one side wall and transverse slits on the other side wall. The transverse slits include a first transverse slit 2211 , a second transverse slit 2212 and a third transverse slit 2213 .

[0070] The operating button 226 is transversely disposed at the operating hole 2214 and is slidably connected to the housing 221 . One end of the operating button 226 extends out of the housing 221 , and the other end is provided with a flange to prevent the operating button 226 from sliding out of the housing 221 .

[0071] The common terminal 222 is disposed in the first transverse slot 2211, one end of which extends out of the housing 221 along the transverse slot, and the other end of which is divided into a first end 2221 and a second end 2222. The first end 2221 extends transversely, and the second end 2222 is bent longitudinally and then extends transversely, and abuts against the inner side of the side wall of the housing 221 provided with the operating hole 2214;

[0072] The normally open terminal 224 is disposed in the second transverse slot 2212 , with one end extending out of the housing 221 along the second transverse slot 2212 , and the other end bending and extending toward a side away from the common terminal 222 .

[0073] The normally closed terminal 223 is disposed in the third transverse slot 2213 , with one end extending out of the housing 221 along the third transverse slot 2213 , and the other end extending toward the side wall of the housing 221 where the operating hole 2214 is disposed, and being bent longitudinally.

[0074] The first connecting member 225 is horizontally arranged, with one end clamped with the first end portion 2221 and the other end abutting against the normally closed terminal 223 . The middle portion is sleeved on the outside of the second end portion 2222 and has an arc-shaped extension edge 2251 extending therefrom.

[0075] The middle portion of the extension edge 2251 abuts against the side wall of the housing 21 where the operation hole 2214 is provided, and one end is engaged with the second end portion 2222 .

[0076] The end of the first connecting member 225 that abuts against the normally closed terminal 223 is farther from the side wall of the housing 21 provided with the operating hole 2214 than the other end. The oblique arrangement of the first connecting member 225 allows the first connecting member 225 to react sensitively after the operating button 226 is pressed, disconnecting from the normally closed terminal 223 and connecting to the normally open terminal 224. The arrangement of the extended edge 2223 will rebound the first connecting member 225, ensuring that the first connecting member 225 is in a fixed position when the operating button 226 is not touched, making the micro switch 22 more accurate and not easily sending out an erroneous signal.

[0077] The two ends of the connecting wire 24 are respectively connected to the common terminal 222 of the two micro switches 22 , the current outlet terminal 31 is connected to the normally closed terminal 223 of one micro switch 22 , and the current inlet terminal 32 is connected to the normally closed terminal 223 of the other micro switch 22 .

[0078] The operating rod 23 pushes the operating button 226, and the operating button 226 pushes the first connecting member 225, so that the first connecting member 225 is disconnected from the normally closed terminal 223 and connected to the normally open terminal 224, thereby sending out an abnormal signal.

[0079] The joystick 23 pushes the operating button 226, and the operating button 226 pushes the first connecting member 225, so that the first connecting member 225 is disconnected from the normally closed terminal 223 and connected to the normally open terminal 224, thereby sending out an abnormal signal.

[0080] In this embodiment, the structure of the micro switch 22 is simple, practical, and accurate. Under normal conditions, the first connector 225 connects the common terminal 222 and the normally closed terminal 223, and the circuit is in a conducting state. After the fuse is activated, the first connector 225 connects the common terminal 222 and the normally open terminal 224, and the circuit is disconnected, and an abnormal signal is issued. Through the setting of the housing 221, the micro switch 22 has a fixed position, and under normal conditions, it will not be activated. It will only be activated when the fuse is blown, which is accurate and reliable.

[0081] The joystick includes a first side plate 231 and a second side plate 232 .

[0082] The first side plate 231 is vertically disposed between the operating button 226 of the micro switch 22 and the fuse trigger mechanism 11 , and both ends thereof extend longitudinally.

[0083] The second side plate 232 is disposed horizontally, with one end fixedly connected to the top edge of the first side plate 231 , and the other end extending laterally away from the fuse trigger mechanism 11 , and the bottom surface abutting against the top surface of the micro switch 22 .

[0084] In this embodiment, the structure of the joystick is simple and reliable, and is easy to obtain materials and is conducive to production and use.

[0085] like Figure 3 As shown, the micro switch fixing member 21 includes a first plate body 211 , a second plate body 212 , a third plate body 213 and a fourth plate body 214 .

[0086] The first plate 211 is disposed longitudinally, and one side thereof abuts against a side surface of the multiple fuse 1 on which the fuse triggering mechanism 11 is disposed.

[0087] The second plate body 212 is vertically arranged, and a top edge is fixedly connected to the other side edge of the first plate body 211 .

[0088] The second plate body 212 is symmetrically provided with a first opening and a second opening. The first opening is used for the current inlet terminal 32 to pass through, and the second opening is used for the current outlet terminal 31 to pass through.

[0089] A hook 217 is disposed on the bottom edge of the second plate 212 for engaging with a side surface of the multi-connected fuse 1 .

[0090] The third plate 213 and the fourth plate 214 are both vertically arranged and symmetrically arranged at both ends of the first plate 211. The top edge is fixed to the end of the first plate 211, the side away from the fuse trigger mechanism 11 is connected to the end of the second plate 212, and the other side is close to the multi-piece fuse 1.

[0091] The first plate 211 is fixedly connected to the multi-piece fuse 1 by means of vertically arranged screws 4 .

[0092] In this embodiment, the micro switch fixing member 21 has a simple structure and is easy to use and produce.

[0093] A planar guide groove 216 is disposed on the bottom surface of the first plate 211 .

[0094] The planar guide groove 216 extends in the transverse direction and is adapted to the second side plate 232 for being slidably connected to the second side plate 232 and accurately positioning the sliding track of the joystick.

[0095] In this embodiment, the provision of the planar guide groove 216 makes the pushing of the joystick 23 more flexible and reliable, thereby improving the accuracy of the device.

[0096] The micro switch 22 further includes two positioning posts 227 , and the positioning posts 227 vertically penetrate the housing 221 .

[0097] Positioning holes 218 are symmetrically arranged on both sides of the planar guide groove 216 .

[0098] The outer contour of the positioning column 227 is adapted to the positioning hole 218 .

[0099] The micro switch fixing member 21 is positioned by the positioning column 227 and the positioning hole 218 .

[0100] In this embodiment, the positioning column 227 and the positioning hole 218 are used together to facilitate the fixing of the micro switch 22, making the device simpler, more reliable and easier to use.

[0101] The micro switch fixing member 21 further includes a spacer plate 215 disposed vertically.

[0102] The spacer plate 215 is disposed between the two micro switches 22 , with its top edge fixed to the bottom surface of the first plate body 211 , and a groove formed between one side edge and a side surface of the second plate body 212 close to the positioning hole 218 for the connecting wire 24 to pass through.

[0103] In this embodiment, the provision of the spacer plate 215 makes the structure of the micro switch fixing member 21 more stable and facilitates the installation of the micro switch 22 .

[0104] The first plate body 211, the second plate body 212, the third plate body 213, the fourth plate body 214 and the spacer plate 215 are integrally formed.

[0105] In this embodiment, the structure of the micro switch fixing member 21 is an integrated structure, which is reliable in fixing and has a more beautiful appearance.

[0106] The first side plate 231 and the second side plate 232 are an integral structure.

[0107] In this embodiment, the integrated setting of the joystick makes the joystick structure more stable, which is convenient for production and use.

[0108] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
