Description

Technical Field

[0001] The utility model relates to an electronic fishing float. Background Art

[0002] An electronic fishing float is an electronic product that can illuminate to alert anglers of prey biting the hook on their fishing rod. Currently, the electronic fishing floats available on the market mainly have a light bead welded to one of the short ends of the circuit board, and two rigid conductive metal terminals of different lengths are welded to the other end of the short end, which are connected to the positive and negative poles of the battery. These two conductive metal terminals need to be cut into inclined edges. The shorter metal terminal, as the negative terminal of the battery, is inserted into the inner hole of a plastic sleeve, and is connected to the cylindrical steel needle of the battery through the edge at the bottom of the terminal. The longer metal terminal, as the positive terminal of the battery, is connected to the battery casing through the slot on the outside of the plastic sleeve and the edge at the bottom. This structural design, which tightens the connection between the battery and the circuit board by simultaneously inserting the cylindrical battery terminal of the battery into the inner hole of the plastic sleeve, has the following defects:

[0003] If two conductive metal terminals are fixed to the PCB board by manual welding, it will lead to low efficiency, high cost and low product yield. The operators need to bear the pollution such as fume generated by welding. The efficiency and output of manual welding are limited, and the consistency of welding products is low. In addition, the welded metal terminals need to be cut, which has high requirements on the cutting angle and direction of the metal terminals, multiple processes and high process costs.

[0004] If automated equipment is used for welding, the investment in one-time customized equipment is high, and the matching equipment operators need to design and adjust the board loading, metal terminal loading, and circuit board unloading according to different products;

[0005] When assembling circuit boards, the metal terminals soldered on the PCB are quite sharp, which increases the risk of injury to assemblers;
