Electrical connector

The present invention provides an electrical connector, and more particularly an electrical connector that can increase the speed of maintenance and repair of an electrical connector when it is damaged, and effectively reduce its cost.

According to the electric connector, there is also its evolution technology. The early USB connector was 2.0 specification, and the later 3.0 specification was developed. In the current technology, it is more advanced to provide positive and negative insertion, and the speed ratio is 3.0. The C-type connector is faster, so the history of the connector is fascinating.

A typical USB C-type connector has an I/O socket at one end and a soldering portion at the other end of the board end or the wire end. However, when the connector is constructed, the connector is connected to the circuit board or the wire by the soldering portion. Solder together to form a circuit conduction, which is the current USB C-type connector.

However, the connector is most often subjected to differential conduction. When it is plugged and unplugged for a long time, the conductive metal paste is inevitably damaged, which makes the conduction effect worse, and often the connection is not connected or connected to the half of the disconnection. This problem requires the entire connector to be re-desoldered for repair/replacement, and then re-welded after processing, which is very cumbersome, time consuming, and costly.

Therefore, how to solve the above problems and deficiencies in the above-mentioned applications, that is, the inventors of the present invention and those involved in the industry are eager to study the direction of improvement.

Therefore, the inventors of the present invention have collected the relevant materials in view of the above-mentioned shortcomings, and have evaluated and considered them through various parties, and have accumulated many years of experience in the industry, and have continuously designed and modified such electrical connectors. In the case of damage, the patent holder of the electrical connector that increases its maintenance update speed and effectively reduces its cost.

The main purpose of the present invention is that the electrical connector is mainly electrically connected and assembled by the first connector and the second connector, so that when the electrical connector is damaged due to long-term insertion and removal, it can be replaced separately. The first connector can be used, and it is not necessary to re-solder after the entire unwelding process. Overall, the speed of repair and replacement is accelerated, and the cost of the first connector is replaced by a separate repair, and the cost is greatly reduced.

The main structure of the present invention capable of achieving the above object includes a first connector, wherein the first connector comprises a first transmission conductor set and a second transmission conductor set, and the first transmission conductor set has one end defining a first transmission conductor front end contact portion And the other end is defined by a first transmission conductor front end contact group extending rearwardly defining a first transmission conductor rear end contact group, and the second transmission conductor set has one end defining a second transmission conductor front end contact group, and The first transmission conductor front end contact portion is formed to form an upper and lower double row corresponding, and the other end of the second transmission conductor group is extended from the second transmission conductor front end contact portion to define a second transmission conductor rear end contact portion; In addition, a shielding spacer is disposed between the first transmission conductor set and the second transmission conductor set, and the first transmission conductor set and the second transmission conductor set are collectively received in a first insulating colloid.

Moreover, the first connector and the second connector are electrically connected to each other, and the second connector includes a third transmission conductor group and a fourth transmission conductor group, wherein the third transmission conductor group has one end defined with the first transmission The rear end contact portion of the conductor is electrically connected to the third transmission conductor front end contact portion, and the other end is extended by the third transmission conductor front end contact portion to define a third transmission conductor rear end welding portion, and the fourth transmission The conductor set defines a fourth transmission conductor front end contact group electrically connected to the second transmission conductor rear end contact portion at one end, and the other end is defined by a fourth transmission conductor front end contact portion extending rearwardly to define a fourth The transmission conductor rear end welding portion group, in addition, the third transmission conductor group and the fourth transmission conductor group are collectively housed in a second insulating glue body, and the outermost layer is shielded by the first connector The two connectors are coated together.

When the first connector is inserted into the first connector, the first transmission conductor set and the second transmission conductor group are transmitted to the third transmission conductor group and the fourth transmission conductor group of the second connector to form an information link. And the second transmission conductor front-end contact group and the first transmission conductor front-end contact group form upper and lower double-row correspondence, forming a plug-in interface that can be inserted and reversed, such as a USB C-type connector; if the second transmission conductor front-end contact group When the contact portion of the front end of the first transmission conductor is worn out for a long time, the user can separately replace the first connector, mainly because the first connector and the second connector are connected by interpolation, instead of Soldering, so it can be easily replaced separately.

With the above technology, after the long-term insertion and removal of the conventional connector, the conductive metal paste is inevitably damaged, so that the conduction effect is deteriorated, and the problem that the connection is not connected or connected to the half of the disconnection is often caused. In order to solve this problem, the entire connector must be re-desolder repaired/replaced, and then processed. Re-welding, which is cumbersome, time-consuming, and costly, is a breakthrough in the overall problem, and achieves the practical progress of the present invention as described above.
