Reinforcing tool for lap welding of rigid pin and flexible lead

Abstract

The invention provides a reinforcing tool for lap welding of a rigid pin and a flexible lead, a tool main body is integrally a cylinder, and two ends of the tool main body are a handle end and an operation end; the non-welding end of the flexible lead is detachably connected with the operation end, and the flexible lead is parallel to the tool body. The binding wire clamping device is fixedly connected with the tool main body; the winding device comprises a binding wire roller for providing a binding wire, a guide nut sleeved on the tool main body, and a binding wire bracket fixedly connected with the guide nut, and the binding wire bracket is arranged on one side close to the operation end; the free end of the binding wire can be fixed or loosened by the wire clamping mechanism after penetrating through a wire penetrating hole in the front end of the binding wire support. The guide nut is coaxially sleeved outside the tool body, and when the guide nut rotates, the binding wire support moves in the axial direction of the tool body and rotates at the same time. And the binding wire can be wound on the lap joint part of the flexible lead and the rigid pin, so that the mechanical binding and fixing effects are achieved.

Description

technical field [0001] The invention relates to the technical field of electronic assembly, in particular to a reinforcement tool for lap-welding soft leads with rigid leads. Background technique [0002] Some devices with rigid pins, such as power modules, filters, relays, and TO package MOS tubes, need to use soft leads to realize the electrical connection between the rigid pins and printed boards or other components during the electrical assembly process. At present, there are two welding methods between the rigid lead and the flexible lead. One is "wrapping welding" between the flexible lead and the rigid lead, that is, welding is performed after the core of the flexible lead is spirally wound in the circumferential direction of the rigid lead. The winding process has a certain mechanical fixation effect on the flexible lead, which makes this method have the advantage of high reliability and is widely used in high-reliability products such as aerospace. However, when th...
