Description

Technical Field

[0001] This utility model mainly relates to the field of fuse holders, specifically to a short-circuit protection safety fuse holder. Background Technology

[0002] As an important overcurrent protection component, fuses are widely used in various electrical and electronic devices and circuits. The fuse holder, as the carrier of the fuse, plays a crucial role in securing the fuse, providing a reliable electrical connection, and facilitating replacement. Traditional fuse holders typically include an insulating housing, metal conductive terminals (such as input / output springs or tabs) housed within the housing, and structures for accommodating and holding the fuse caps (such as slots or clips).

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] If the operation is not careful or the space is limited during the insertion of the fuse, the fuse body or end cap may tilt or slip, causing it to come into contact with two terminals that should not be connected at the same time, resulting in a short circuit.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0008] 2. Technical Solution:

[0009] To achieve the above objectives, the technical solution provided by this utility model is as follows: a short-circuit protection safety fuse holder, comprising a base structure, conductive structures provided on both sides of the base structure, connecting structures provided on both sides of the top of the base structure, and a fuse structure provided between the two connecting structures;

[0010] The connecting structure includes multiple horizontal bars, with a connecting bar at the top of each horizontal bar, a socket at the top of the middle of each connecting bar, and first limiting rings on both sides of the inner wall of the socket.

[0011] Furthermore, the base structure includes a base body, slots are provided on both sides of the base body, guide grooves are provided on the top and bottom of both sides of the inner wall of the slots, and guide grooves are provided inside the slots.

[0015] Furthermore, the fuse structure includes a fuse body, with guide bars at both ends of the fuse body, and second limiting rings on both sides of one end of the guide bars.

[0016] 3. Beneficial effects:

[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0018] This invention uses a first limiting ring and a second limiting ring to engage with each other, thereby fixing the fuse body between two connecting structures and preventing short circuits between them. Furthermore, the multiple connecting strips connected in parallel allow current to be diverted to the interior of the multiple connecting strips and connected to external wires through conductive structures, preventing large currents from causing heat buildup inside the fuse holder and affecting short circuits inside the fuse holder.

[0030] Example

[0031] See attached document Figure 1-4 A short-circuit protection safety fuse holder includes a base structure 1, conductive structures 2 are provided on both sides of the base structure 1, connecting structures 3 are provided on both sides of the top of the base structure 1, and a fuse structure 4 is provided between the two connecting structures 3.

[0032] The connecting structure 3 includes multiple horizontal bars 301, with connecting bars 302 at the top of each horizontal bar 301. A socket 303 is provided at the top of the middle of each connecting bar 302. First limiting rings 304 are provided on both sides of the inner wall of the socket 303. Current enters the interior of the connecting groove 204 through the wire and connects to the connecting bar 302 through the groove inside the heat sink 203, allowing the current to enter the interior of the connecting structure 3. Then, the current enters the interior of the fuse structure 4 and is discharged through the connecting structure 3 and the conductive structure 2 on the other side.

[0033] Furthermore, the base structure 1 includes a base body 101, with slots 102 on both sides of the base body 101. Guide grooves 103 are provided at the top and bottom of both sides of the inner wall of the slots 102, and guide grooves 103 are provided inside the slots 102. Connecting holes 105 are provided at the top of both sides inside the base body 101. The connecting holes 105 are connected to the slots 102. The number of connecting holes 105 is set to multiple, and the multiple connecting holes 105 are evenly distributed on the top of the base body 101. After the fuse structure 4 is connected to the connecting structure 3, the connecting strip 302 at the bottom of the horizontal strip 301 is inserted into the connecting hole 105 to fix the connecting structure 3.

[0034] Furthermore, the conductive structure 2 includes a conductive plate 201, one end of which has a pin hole 202 aligned with a positioning hole 104. A pin is provided inside the pin hole 202 and the positioning hole 104. A heat sink 203 is provided inside the base body 101. A connecting groove 204 is provided on the other side of the conductive plate 201. The number of heat sinks 203 is set to multiple. A through groove is provided inside the heat sink 203. When the fuse structure 4 needs to be installed, the conductive plate 201 is inserted into the slot 102, and then the pin is inserted into the positioning hole 104 and the pin hole 202 to fix the conductive plate 201. Then, the external wire contacts the connecting groove 204 and is fixed with bolts.

[0035] Furthermore, the fuse structure 4 includes a fuse body 401, with guide strips 402 at both ends of the fuse body 401. Second limiting rings 403 are provided on both sides of one end of each guide strip 402. The guide strips 402 are L-shaped. The horizontal guide strip 402 is fixed to the fuse body 401, and the vertical guide strip 402 is rotatably connected to the horizontal guide strip 402. The guide strips 402 at both ends of the fuse body 401 are inserted into the socket 303. Then, the vertical guide strip 402 is rotated, causing the guide strip 402 to drive the second limiting ring 403 into the bottom of the first limiting ring 304, thereby fixing the fuse body 401.

[0036] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, 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 modifications and improvements all fall within the protection scope of this utility model.
