Five-pole plug

Abstract

The invention discloses a five-pole plug which comprises an insulating body assembly and a first pole conductor, a second pole conductor, a third pole conductor, a fourth pole conductor and a fifth pole conductor mounted in the insulating body assembly and insulated to each other, wherein the insulating body assembly comprises a first insulating core; the first pole conductor and the second pole conductor are same in shape, the front ends of the first pole conductor and the second pole conductor are symmetrically distributed on the left and right sides of the front end of the insulating core, and the peripheries of the front ends of the first pole conductor and the second pole conductor as well as the periphery of the front end of the insulating core are connected with plastic fastening rings in a sleeving manner, so that the front ends of the first pole conductor and the second pole conductor and the front end of the insulating core are fixed to each other. According to the five-pole plug disclosed by the invention, in the plugging process, the first conductor and the second conductor are not separated toward the left and right sides, so that the conducting function of a product is ensured, and the service life of the product is prolonged. As the first pole conductor and the second pole conductor are symmetrically distributed on the left and right sides of the front end of the insulating core, the thickness of an insulating material part between two poles is greatly increased, so that the anti-insulating capacity between two poles is enhanced and the conducting function of the product is improved.

Description

Technical field: [0001] The invention relates to the technical field of plug products, in particular to a five-pole plug that can enhance the insulation resistance between the poles. The five-pole plug can meet the requirements of being inserted and used, and the top of the plug is separated by two conductive electrodes at the end of the socket and contacted simultaneously Inductive signal transmission requirements. Background technique: [0002] In the past, multi-pole single-head plugs and corresponding multi-pole sockets were used in the electrical connection of various electronic devices. The multi-pole single-head plugs provided on peripheral electronic devices such as earphones and multi-function portable phones, Multi-pole sockets on the main body of electronic equipment such as portable music players constitute connectors. [0003] The number of poles of the existing multi-pole single-head plug is at most five poles, and the poles of all the conductive bodies are coaxially...

AI Technical Summary

Problems solved by technology

[0003] The number of poles of the existing multi-pole single-head plug is at most five poles, and the poles of all conductors are distributed in coaxial steps. On the premise of keeping the diameter of Φ3.5mm, five poles are distributed. The shaft conductor leads to the reduction of the insulator between the poles, thus weakening the insulation resistance between the poles

Moreover, it cannot meet the signal transmission requirements that the top of the product is separated by the two conductive electrodes at the end of the socket and simultaneously contacted and sensed when the product is inserted and used.
