Abstract
Description
Technical Field
[0001] This utility model relates to the field of fuses, and in particular to a fuse blowout signal output device. Background Technology
[0002] A thermal fuse, also known as a thermal circuit breaker, is typically installed in appliances that are prone to overheating. If an appliance malfunctions and overheats, the thermal fuse will automatically melt and cut off the power supply when the temperature exceeds the abnormal level, preventing the appliance from causing a fire.
[0003] However, current fuses only disconnect the power supply to the device when they trip. When some important devices are disconnected, they cannot quickly transmit the signal that the device is disconnected, which leads to delays in the maintenance of the device when it is powered off. Utility Model Content
[0004] Purpose of the utility model: The purpose of this utility model is to solve the problems in the prior art and provide a fuse blowout signal output device.
[0005] Technical solution: A fuse blowout signal output device is proposed, comprising:
[0006] Housing, fuse unit body, guiding device, and triggering device;
[0007] The fuse device body, the guiding device, and the triggering device are located inside the housing;
[0008] The fuse device body includes a first conductive rod, a second conductive rod, and a fuse. One end of the first conductive rod and the second conductive rod are connected by the fuse, and the inner side of the second conductive rod is connected to the outer shell by a first spring.
[0009] The triggering device includes a third conductive rod and a fourth conductive rod;
[0010] When the fuse breaks, the second conductive rod can squeeze the guiding device through the action of the first spring to squeeze the third and fourth conductive rods to resist each other.
[0011] The third and fourth conductive rods are respectively connected to the output structure.
[0012] Preferably, the first conductive rod is fixedly connected to the housing, and the second conductive rod is hinged to the housing at the end away from the fuse.
[0013] Preferably, one end of the first spring is connected to the outer casing via a spring fixing member.
[0014] Preferably, the guiding device includes an insulating pad disposed on the housing, the insulating pad and the end of the second conductive rod near the fuse are connected to the insulating pad, and the housing is provided with an observation hole;
[0015] The insulating pad can only be observed through the inspection hole when the fuse breaks.
[0016] Preferably, one end of the third conductive rod is hinged to the outer casing, and the fourth conductive rod is fixed to the outer casing.
[0017] Preferably, a second spring is provided between the third conductive rod and the fourth conductive rod. The second spring is an insulating spring. One end of the third conductive rod includes a first contact block, and one end of the fourth conductive rod includes a second contact block.
[0018] When the fuse is tripped, the second conductive rod can squeeze the third conductive rod through the guiding device, which overcomes the elastic force of the second spring and causes the first contact block and the second contact block to come into contact, so that the third conductive rod and the fourth conductive rod are connected.
[0019] Preferably, the output mechanism includes a base located at one end of the housing, and the base is provided with four sockets respectively. One end of the first conductive rod, the second conductive rod, the third conductive rod and the fourth conductive rod are respectively connected to a plug block that can be inserted into the four sockets.
[0020] The base is also provided with two signal terminals and two main circuit terminals, which are electrically connected to four sockets respectively, so that the two signal terminals can be electrically connected to the third conductive rod and the fourth conductive rod respectively, and the two main circuit terminals can be electrically connected to the first conductive rod and the second conductive rod respectively.
[0021] Beneficial effects:
[0022] When the fuse trips, the first spring immediately compresses the second conductive rod, which in turn compresses the third conductive rod through the insulating pad. This causes the first and second contact blocks to connect electrically through the third conductive rod, thus enabling the third and fourth conductive rods to conduct electricity. Specifically, the third and fourth conductive rods can be electrically connected to the host computer, and the resulting electrical signal allows the host computer to issue further instructions and promptly notify the maintenance personnel.

[0033] In response to the problems existing in the current technology, combined with Figure 1-4 A fuse blowout signal output device, comprising:
[0034] 1. Housing, fuse device body, guiding device and triggering device;
[0035] The fuse device body, the guiding device, and the triggering device are located inside the housing 1;
[0036] The fuse device body includes a first conductive rod 2, a second conductive rod 3 and a fuse 4. One end of the first conductive rod 2 and the second conductive rod 3 are connected by the fuse 4. The inner side of the second conductive rod 3 is connected to the outer shell 1 by a first spring 5.
[0037] The triggering device includes a third conductive rod 6 and a fourth conductive rod 7;
[0038] When the fuse 4 breaks, the second conductive rod 3 can squeeze the guiding device through the action of the first spring 5 to squeeze the third conductive rod 6 and the fourth conductive rod 7 to resist each other.
[0039] The third conductive rod 6 and the fourth conductive rod 7 are respectively connected to the output structure.
[0040] Specifically, under normal use, the first conductive rod 2 forms a normal current circuit through the second conductive rod 3 and the fuse 4;
[0041] When fuse 4 overheats and burns out, the spring force of the first spring 5 pushes the second conductive rod 3, causing the third conductive rod 6 and the fourth conductive rod 7 to come into contact, thus making the third conductive rod 6 and the fourth conductive rod 7 conduct electricity.
[0042] By connecting to an existing host computer or controller, it is easy to control the alarm and notify staff. Since this solution mainly focuses on signal acquisition, the specific method of controlling the alarm via a host computer or controller is existing technology and will not be elaborated upon.
[0043] In some specific embodiments, the first conductive rod 2 is fixedly connected to the outer casing 1, and the second conductive rod 3 is hinged to the outer casing 1 at the end away from the fuse 4.
[0044] Specifically, when the first conductive rod 2 is in a fixed state, the second conductive rod 3 can be driven to rotate around the hinge position when the first spring 5 pushes the second conductive rod 3.
[0045] In some specific embodiments, one end of the first spring 5 is connected to the outer casing 1 via a spring fixing member 8.
[0046] Specifically, one end of the first spring 5 is effectively fixed.
[0047] In some specific embodiments, the guiding device includes an insulating pad 9 disposed on the housing 1, the insulating pad 9 being connected to the insulating pad 9 at one end of the second conductive rod 3 near the fuse 4, and the housing 1 being provided with an observation hole 10;
[0048] The insulating pad 9 can only be observed through the observation hole 10 when the fuse 4 breaks.
[0049] Specifically, in addition to notifying staff of the fuse 4 breakage via the third conductive rod 6 and the fourth conductive rod 7, staff can also quickly observe the insulating pad 9 in the observation hole 10 to quickly observe the breakage of the fuse 4.
[0050] In some specific embodiments, one end of the third conductive rod 6 is hinged to the outer casing 1, and the fourth conductive rod 7 is fixed to the outer casing 1.
[0051] Specifically, when the insulating pad 9 presses against the third conductive rod 6, the third conductive rod 6 can rotate.
[0052] In some specific embodiments, a second spring 11 is provided between the third conductive rod 6 and the fourth conductive rod 7. The second spring 11 is an insulating spring. One end of the third conductive rod 6 includes a first contact block 12, and one end of the fourth conductive rod 7 includes a second contact block 13.
[0053] When the fuse 4 is disconnected, the second conductive rod 3 can squeeze the third conductive rod 6 through the guiding device, which overcomes the elastic force of the second spring 11 and makes the first contact block 12 and the second contact block 13 abut against each other, so that the third conductive rod 6 and the fourth conductive rod 7 are connected.
[0054] In some specific embodiments, the output mechanism includes a base 14 located at one end of the housing 1, and four insertion holes 15 are respectively provided on the base 14. One end of the first conductive rod 2, the second conductive rod 3, the third conductive rod 6 and the fourth conductive rod 7 are respectively connected to a plug block that can be inserted into the four insertion holes 15, so as to facilitate quick installation and disassembly.
[0055] The base 14 is also provided with two signal terminals 17 and two main circuit terminals 18, which are electrically connected to four sockets 15 respectively, so that the two signal terminals 17 can be electrically connected to the third conductive rod 6 and the fourth conductive rod 7 respectively, and the two main circuit terminals 18 can be electrically connected to the first conductive rod 2 and the second conductive rod 3 respectively.
[0056] Specifically, it facilitates convenient connection to external controllers or host computers via signal terminal 17;
[0057] It is connected to the external main power supply circuit through two main circuit terminals 18.
[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
