Embodiment Construction

[0010] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0011] like figure 1 , figure 2 As shown, the present invention is a new type of ignition needle, comprising a lead needle 1, a lead wire 2, an ignition electrode 3 and a ceramic jacket 4 arranged outside the ignition electrode 3. The lead needle 1 is arranged at the front end of the ignition electrode 1, and the lead wire 2 is arranged at the front end of the ignition electrode 1. the end of the ignition electrode 3;

[0012] The inner wall of the ceramic jacket 4 is provided with a retaining ring 5 along the circumferential direction, the outer ring surface of the retaining ring 5 is fitted with the inner wall of the ceramic outer casing 4, the inner ri...

Abstract

The invention discloses a novel ignition needle which comprises a guide needle, a guide line, an ignition electrode and a ceramic sleeve arranged outside the ignition electrode. The guide needle is arranged at the front end of the ignition electrode, and the guide line is arranged at the tail end of the ignition electrode. According to the scheme, glue is not needed, in the assembly process, the ignition electrode is blocked by a check ring on the ceramic sleeve, small force is applied, an elastic stopping sheet slides across the check ring through plasticity of the elastic stopping sheet, the ignition electrode cannot retreat back, a boss is clamped outside the ceramic sleeve at the time, the ignition electrode cannot advance continuously, the position of the ignition electrode is fixed, and assembly is completed. The novel ignition needle is high in assembly efficiency, the assembly quality is guaranteed, and the novel ignition needle is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of ignition needles. Background technique [0002] At present, the ignition needle on the market is that after connecting the ignition electrode with the lead wire and the lead needle, glue the ignition electrode and the ceramic jacket together. This method has a slow assembly speed and relies on the amount of glue to control whether the adhesion is firm or not, and the assembly efficiency and assembly quality are not high. SUMMARY OF THE INVENTION [0003] In order to overcome the above deficiencies, the present invention provides a new type of ignition needle with simple structure and reasonable design, comprising a guide needle 1, a lead wire 2, an ignition electrode 3 and a ceramic jacket 4 arranged outside the ignition electrode 3, which is arranged on the ignition electrode 1 The front end of the wire 2 is arranged at the end of the ignition electrode 3; [0004] The inner wall of the ceramic jacke...
