[0002] A fuse, also known as a circuit breaker or fuse wire, is a one-time component connected to an electronic circuit to protect it. When the current in the circuit is too high, the metal wire or metal piece inside it will generate high temperature and melt, causing an open circuit and interrupting the current, thus protecting the circuit from damage. Surface mount fuses are a relatively new product with higher technical content in the small fuse industry.

[0003] Patent CN219379266U discloses a fixture for reflow soldering surface mount fuses, comprising a wire threading spool, a metal winding clamp, a metal dispensing frame, and a metal soldering frame. The wire threading spool has multiple spaced slots. This utility model has a simple structure and is easy to use. By using the fixture for reflow soldering, the soldering efficiency of surface mount fuses can be greatly improved.

[0004] Although the above-mentioned patent solution can process multiple fuses simultaneously, the fuse welding fixture in the above-mentioned patent is not convenient for adjusting fuses of different sizes or shapes. At present, most welding fixtures only use slots to fix fuses, and the size of the slots is fixed, requiring the preparation of different types of mounting slots for replacement.

[0005] Therefore, a fixture for soldering surface mount fuses is proposed here. Utility Model Content

[0006] This utility model proposes a fixture for welding patch fuses. It uses a moving rod and a second soft pad to push the fuse to a position closer to the first soft pad. The height of the support plate can be adjusted according to the fuse size, so that fuses of different sizes can be fixed inside the working hole for processing.

[0007] This utility model is achieved through the following technical solution: a fixture for welding patch fuses, including a support shell, an installation groove is provided inside the support shell, and multiple sets of working holes are provided on the surface of the support shell, penetrating the support shell and the installation groove. A positioning rod matching the position of the working hole is fixed on the inner side wall of the installation groove, and a moving rod corresponding to the position of the positioning rod slides on the inner side wall of the installation groove.

A positioning rod 5 matching the position of the working hole 11 is fixed on the inner side wall of the installation groove 12, and a moving rod 6 corresponding to the position of the positioning rod 5 slides on the inner side wall of the installation groove 12.

[0020] Please refer to this carefully. Figure 4 The positioning rod 5 and the moving rod 6 are respectively set on both sides of the working hole 11. The first soft pad 51 is fixed on the side of the positioning rod 5 near the working hole 11, and the second soft pad 61 is fixed on the side of the moving rod 6 near the working hole 11.

[0021] Please refer to this carefully. Figure 4 and Figure 5 A transmission assembly 7 is provided on one side of the support shell 1 to drive multiple moving rods 6 to move. The transmission assembly 7 includes two connecting rods 71 ​​that slide inside the mounting groove 12, and the two ends of the moving rods 6 are respectively fixed to one side of the two connecting rods 71. One end of the connecting rod 71 slides through the support shell 1 and extends to the outside of the support shell 1. A push rod 72 is fixed at one end of the two connecting rods 71 ​​located outside the support shell 1.

[0022] Please refer to this carefully. Figure 5 The push rod 72 is internally fixedly sleeved with a first connecting sleeve 73, and the first connecting sleeve 73 is internally threaded with a first threaded rod 74. The end of the first threaded rod 74 near the support shell 1 is rotatably sleeved with a first limiting collar 75, and the first limiting collar 75 is fixed on one side of the support shell 1.

[0023] In the above scheme, rotating the first threaded rod 74 drives the push rod 72 to move through the first connecting sleeve 73, and drives the connecting rod 71 to slide inside the mounting groove 12, so that the moving rod 6 and the second soft pad 61 push the fuse to move closer to the first soft pad 51, and fix the fuse between the first soft pad 51 and the second soft pad 61.

[0024] Please refer to this carefully. Figure 3 A connecting plate 2 is fixed to one side of the support shell 1. A lower cover plate 3 is rotatably connected to one side of the connecting plate 2 at the bottom of the support shell 1. A first storage groove 31 is opened inside the lower cover plate 3.
