Abstract: An inductor choke coil wire interference prevention structure includes a choke coil having a flat body portion wound into a continuous electrical coil portion, two end portions respectively downwardly extending from two opposite ends of the flat body portion and respectively bent into a respective soldering electrode. An extension tip is located on a distal end of each end portion remote from the flat body portion, and a layer of insulating film covers a contact surface of the end portion or an adjacent contact surface of the electrical coil portion to allow direct contact between the electrical coil portion and the contact surface of the end portion without causing electrical conduction or shorting.

Abstract: A waterproof and portable strap comprises a hanging strap and a holding means for carrying a small-type portable electronic device. The hanging strap has coupling heads on both sides, wherein the coupling heads have openings and closed trenches, and the closed trenches have several coupling parts. The closed trench of one coupling head has a taper surface. The holding means is a casing having a receiving trench and a closed surface on both sides for protecting the electronic device and stretching out a terminal portion, wherein the holding means has several coupling parts for coupling with the coupling parts of one closed trench of one coupling head, and the holding means has an exposed outer surface for insertion into the other closed trench of the other coupling head. The holding means has several retaining parts corresponding to the other coupling parts of the other closed trench.
