Connection contact, charging data line, electronic device and preparation method for connection contact

Abstract

The present invention is suitable for the charging contact and data connection contact technology field, and discloses a connection contact, a charging data line, an electronic device and a preparation method of the connection contact. The connection contact is a fast ion conductor ceramic, or a contact surface of the connection contact is the fast ion conductor ceramic. The front end of a line body of the charging data line is equipped with the above connection contact, and the electronic device is equipped with the above connection contact. The preparation method comprises the following steps of preparing the fast ion conductor ceramic and a metal matrix, and welding or installing the fast ion conductor ceramic on the metal matrix. The connection contact, the charging data line and the electronic device provided by the present invention use the fast ion conductor ceramic as the connection contact, are small and stable in contact resistance, good in corrosion resistance and very good in stability, and can be applied to various environments for a long time. The fast ion conductor ceramic is high in rigidity and good in wear resistance, mechanical strength and reliability, and can be plugged in and out repeatedly.

Description

technical field [0001] The invention belongs to the technical field of charging contacts and data connection contacts, and in particular relates to a connection contact, a charging data line, electronic equipment and a method for preparing a connection contact. Background technique [0002] The current electronic equipment and other equipment, the exposed charging contacts or connecting contacts are realized by metal electroplating with gold, which has the following disadvantages: [0003] 1. Metal parts need to be plated with thick gold to prevent oxidation and corrosion and ensure small contact resistance. The cost of gold plating is very high; [0004] 2. The gold plating process usually uses electroplating. The electroplating solution itself is highly toxic and contains heavy metals, which is not environmentally friendly; [0005] 3. Even if the gold is thickly plated, because the gold contains cobalt, nickel or other impurities, and the gold plated has pores, it will s...

[0003] 1. Metal parts need to be plated with thick gold to prevent oxidation and corrosion and ensure small contact resistance. The cost of gold plating is very high;

[0004] 2. The gold plating process usually uses electroplating. The electroplating solution itself is highly toxic and contains heavy metals, which is not environmentally friendly;

[0005] 3. Even if the gold is thickly plated, because the gold contains cobalt, nickel or other impurities, and the gold plated has pores, it will still corrode when there is a voltage difference between the electrodes and there is water or sweat remaining. Or oxidation, forming electrolytic corrosion, resulting in increased contact resistance, affecting the charging of electronic equipment, and poor reliability
