A wire-wound resistive motorcycle spark plug cap

Abstract

The invention discloses a winding-resistor type motorcycle spark plug cap. The winding-resistor type motorcycle spark plug cap is characterized in that a cap body (1) is L-shaped and is composed of a first straight pipe (1a) and a second straight pipe (1b) which are perpendicular to each other, a first spring (2) and a conductive cap (3) are mounted in the first straight pipe (1a), a second spring (4), a resistor (5) and a bolt (6) are sequentially mounted in the second straight pipe (1b) from inside to outside, and the resistor (5) comprises a ceramic rod (5a), a metal cap (5b) and an alloy wire (5c). The winding-resistor type motorcycle spark plug cap is simple in structure, easy to assemble and high in assembling efficiency, the whole mounting process can be completed at constant temperature, operating workers are prevented from being scalded, residues in the cap body are easy to clean up, and bad conduction of products can be effectively avoided; the alloy wire and the metal cap are adhered through silver copper slurry, firmness in connection between the alloy wire and the metal cap can be guaranteed under the premise of no damage to the alloy wire, and conduction performance of the winding resistor is effectively improved.

Description

technical field [0001] The invention relates to a motorcycle component, in particular to a wire-wound resistance spark plug cap on a motorcycle engine. Background technique [0002] The wire-wound resistive spark plug cap is an important part of the motorcycle engine. It is used to connect the high-voltage wire and the spark plug. Its quality directly affects the starting performance of the engine. Existing wire-wound resistive motorcycle spark plug caps generally consist of a body, a spring, a conductive cap, a resistor and screws, and generally have the following deficiencies: [0003] 1) The conductive cap is fixed in the body by interference fit, which is inconvenient to disassemble and assemble, and the assembly efficiency is low; [0004] 2) The screw has a round head structure and must be assembled in a hot state (about 150°C) at a high temperature. After cooling, the screw will not rotate in the body; not only that, but the assembly of other parts is also carried ou...

AI Technical Summary

Problems solved by technology

[0003] 1) The conductive cap is fixed in the body with interference fit, which is inconvenient to disassemble and assemble, and the assembly efficiency is low;

[0004] 2) The screw has a round head structure and must be assembled in a hot state (about 150°C) at a high temperature. After cooling, the screw will not rotate in the body; not only that, but the assembly of other parts is also carried out in a hot state. On the one hand, the assembly The process is complicated, the assembly operation is inconvenient, and the operator is easy to burn his hands; on the other hand, the residue in the body is not easy to clean up, which may easily cause poor conduction of the product;

The welding process between the alloy wire and the metal cap is spot welding. Since spot welding is prone to false welding or false welding in the frequent production process, the spot welding between the alloy wire and the metal cap will be damaged during the use of the wirewound resistor. Easy to fall off, resulting in non-conduction of the winding resistor
