[0025] In an embodiment of the present utility model, as Figures 1-4As shown in the figure, a patch jumper with an insulating sleeve includes an insulating sleeve 1 and a conducting piece 2. The insulating sleeve 1 is detachably sleeved on the conducting piece 2. The conducting piece 2 includes a main sleeved piece 21, connecting pieces 22 and welding pieces 23. The left and right ends of the main sleeved piece 21 are respectively connected to one ends of the two connecting pieces 22. The other ends of the two connecting pieces 22 are respectively connected with the welding pieces 23. The two connecting pieces 22 are inclined. The welding pieces 23 and the main sleeved piece 21 are horizontally arranged, and the welding pieces 23 are located below the main sleeved piece 21. In this embodiment, the number of the connecting pieces 22 and the welding pieces 23 is two respectively. The left and right ends of the main sleeved piece 21 are respectively connected to one ends of the two connecting pieces 22. The other ends of the two connecting pieces 22 are respectively connected with the welding pieces 23. The main sleeved piece 21, the connecting pieces 22 and the welding pieces 23 are of an integrally formed structure. When the insulating sleeve 1 is sleeved on the conducting piece 2, specifically, the end of the welding piece 23 is inserted into one end of the insulating sleeve 1 until the end of the welding piece 23 passes through the other end of the insulating sleeve 1. At this time, the insulating sleeve 1 is sleeved on the outer surface of the main sleeved piece 21. The two connecting pieces 22 are located on the left and right outer sides of the insulating sleeve 1 and are inclined. The two welding pieces 23 are located outside the two connecting pieces 22. The welding pieces 23 are located below the main sleeved piece 21. The two welding pieces 23 are used for welding on a circuit board, so that the conducting piece 2 forms a bridge-like structure. The insulating sleeve 1 plays an insulating role, preventing the main sleeved piece 21 of the conducting piece 2 from being accidentally touched by other metals or conductors, resulting in electric leakage or short circuit. Through the insulating sleeve 1, the conducting piece 2, the main sleeved piece 21, the connecting pieces 22 and the welding pieces 23, the insulating sleeve 1 can be detachably sleeved on the conducting piece 2. Compared with the patch jumper with a coating structure or canned injection molding, this application is not only convenient for installation, but also convenient for replacing the insulating sleeve 1 when it is damaged or fails. Moreover, there is no need to use high-cost LCP materials and plug-in machines, and the production cost is greatly reduced, achieving the effect of improving the production efficiency and maintenance efficiency of the patch jumper.

[0026] As Figures 2-4 shown, a first outer fillet 3 is provided at the connection between the connecting piece 22 and the main sleeved piece 21. In this embodiment, the first outer fillet 3 is provided at the connection between the connecting piece 22 and the main sleeved piece 21. The first outer fillet 3 bulges and bends outward and faces upward of the connecting piece 22. The arc connection structure is adopted instead of the angular connection structure, making the connection between the connecting piece 22 and the main sleeved piece 21 smoother and not easily bent and broken.

[0027] As Figures 2-4As shown, a first inner fillet 4 is provided at the connection between the connecting piece 22 and the main sleeved piece 21, and the first inner fillet 4 faces downward of the main sleeved piece 21. In this embodiment, a first inner fillet 4 is provided at the connection between the connecting piece 22 and the main sleeved piece 21. The first inner fillet 4 is recessed and bent inward and faces downward of the main sleeved piece 21. The first inner fillet 4 is directly below the first outer fillet 3. The arc connection structure is adopted instead of the angular connection structure, making the connection between the connecting piece 22 and the main sleeved piece 21 smoother and not easily bent and broken.

[0028] As Figures 2-4 shown, a second inner fillet 5 is provided at the connection between the connecting piece 22 and the welding piece 23. In this embodiment, a second inner fillet 5 is provided at the connection between the connecting piece 22 and the welding piece 23. The second inner fillet 5 is recessed and bent inward, and the second inner fillet 5 faces upward of the welding piece 23. The arc connection structure is adopted instead of the angular connection structure, making the connection between the connecting piece 22 and the welding piece 23 smoother and not easily bent and broken.

[0029] As Figures 2-4 shown, a second outer fillet 6 is provided at the connection between the connecting piece 22 and the welding piece 23, and the second outer fillet 6 is located below the second inner fillet 5. In this embodiment, the second outer fillet 6 is provided at the connection between the connecting piece 22 and the welding piece 23. The second outer fillet 6 bulges and bends outward, and the second outer fillet 6 faces downward of the main sleeved piece 21. The arc connection structure is adopted instead of the angular connection structure, making the connection between the connecting piece 22 and the welding piece 23 smoother and not easily bent and broken.

[0030] As Figures 1-2 shown, the material of the insulating sleeve 1 is high-temperature resistant silica gel. In this embodiment, the insulating sleeve 1 is specifically a high-temperature resistant silica gel sleeve, which has a relatively high insulation resistance value, can effectively prevent current leakage, and ensure the safe operation of the circuit. In a high-temperature environment, the silica gel can still maintain stable insulation performance and will not fail due to temperature rise. This is particularly important for the patch jumper that needs to withstand high temperatures. And the high-temperature resistant silica gel can usually withstand relatively high temperatures, generally up to above 200 °C, and even up to above 300 °C. This characteristic enables it to maintain stable performance in a high-temperature working environment and will not deform or be damaged due to high temperature. The silica gel can still maintain the stability of its physical and chemical properties at high temperatures and is not easily aged, thus extending the service life of the patch jumper. Further, the high-temperature resistant silica gel usually has good flexibility, which makes it easy to install and use, can closely fit the main sleeved piece 21, and provides better insulation protection.

[0031] As Figures 1-2As shown, the material of the guide piece 2 is copper. In this embodiment, copper is one of the metals with very high electrical conductivity, so it can effectively transmit current, ensuring the stability and reliability of the patch jumper in the circuit; copper has a certain corrosion resistance and can resist the erosion of chemical substances in the environment to a certain extent, thereby extending the service life of the patch jumper; copper has good plasticity and ductility, which makes it easy to be processed into various shapes and sizes during manufacturing to meet the requirements of different patch jumpers. Specifically, according to customer requirements, the material of the guide piece 2 can also be copper alloy.

[0032] As Figures 1-2 shown, the length ratio of the set main piece 21 to the welding piece 23 is 17:2. In this embodiment, the length ratio of the set main piece 21 to the welding piece 23 is set to 17:2, so as to facilitate meeting the processing requirements and daily use requirements.

[0033] As Figures 2-4 shown, the bending angles of the first outer rounded corner 3, the first inner rounded corner 4, the second inner rounded corner 5 and the second outer rounded corner 6 are the same. In this embodiment, the bending angles of the first outer rounded corner 3, the first inner rounded corner 4, the second inner rounded corner 5 and the second outer rounded corner 6 are the same, that is, the two included angles at the connection between the connecting piece 22 and the set main piece 21, and the two included angles at the connection between the connecting piece 22 and the welding piece 21, and the four included angles are the same, specifically 130°, so that the guide piece 2 is easy to process and not easy to break.
