Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pulse igniter, especially relates to a high and low voltage combination wire frame. BACKGROUND

[0002] The high voltage coil and the low voltage coil of the traditional pulse igniter are two independent components. The high voltage coil is composed of a high voltage framework and a secondary winding wound on the high voltage coil, and the low voltage coil is composed of a magnetic rod and a primary winding wound on the magnetic rod. The low voltage coil is sleeved into the high voltage coil, and then the two wire ends of the low voltage coil are separated by manual work and wound on the power terminal, or the two wire ends of the low voltage coil are electrically welded on the power pad of the PCBA board by manual work.

[0003] The traditional low voltage coil manufacturing method has the following disadvantages: 1) cannot realize full-automatic production; the two free ends of the low voltage coil are soft wires, and their positions are random and uncertain. The two free ends need to be separately tin soldered on the two low voltage pads of the PCBA board by manual work, and the excess wire needs to be cut by manual work after tin soldering. This process needs to involve high-difficulty actions such as recognition, grabbing, pressing and cutting of the free ends, and even a customized high-end intelligent robot is difficult to realize, not to mention that the pulse coil is a traditional mature product with limited profit space. If the pulse coil wants to realize full-automatic production, the production cost factor has to be considered. 2) The traditional process has potential product failure risks; in the cutting process of the wire, the wire is inevitably splashed and falls into the pulse coil shell. If this is not found and treated in time, the product will be mixed into the bulk cargo. In the subsequent testing or subsequent use process, the residual wire will cause the high voltage coil to break down and result in product scrap. 3) The traditional process has a dispensing fixing process, which increases the process and has poor consistency; the process is too much, and the wire end of the low voltage coil needs to be separately tin soldered, which cannot be synchronized with the tin soldering of the high voltage coil.
