Sequence bus connector

The present invention relates to a serial bus bar connector, and more particularly to a serial bus bar connector having good electrical contact with a mating connector and wear resistance.

In today's fast-paced society, a variety of handheld electronic devices such as mobile phones, tablets or digital cameras have become popular. In general, an electronic device can be connected to a computer through various types of connectors to perform data transmission, and a universal serial bus (USB) connector with a high transmission speed is widely used.

The insulative housing of the conventional electrical connector is provided with a terminal and a grounding piece, a portion of the grounding plate is exposed outside the opposite side walls of the front end of the insulating body to form a pair of electrical contacts for connecting with the pair of connectors A pair of elastic buckle arms make electrical contact. Since the entire grounding piece, including the electrical contact portion, is a plate-like structure, it is integrally stamped by a plate-shaped metal piece having the same thickness, that is, the thickness of the electrical contact portion and the thickness of the plate-shaped metal piece. Similarly, the thickness of the electrical contact portion is a contact point for electrical contact with the mating connector, such that the electrical contact portion of the conventional connector is equivalent to electrically contacting the mating connector with a point-to-point minimum contact surface. This is easy to cause poor contact between the two.

On the other hand, when the conventional connector is docked with the mating connector, one of the mating connectors protrudes into the interior of the conventional connector through the insulative body. The two corners of the front end will be positioned at the pair of electrical contacts. Generally, since the insulation system is made of a plastic material, and the elastic buckle arm of the butt connector is made of a metal material, the metal elastic buckle arm is easily worn after the two sides are repeatedly inserted and removed.
