Electrical connector structure

This creation belongs to the field of electrical connectors, and in particular to an electrical connector structure that is miniaturized and can avoid shorting of the grounded metal plate and the terminals, thereby simplifying assembly procedures and improving assembly quality.

According to the electrical connector, the main channel for electrical connection and information exchange of various electronic products, because the electrical connector communicates electronic signals through the internal terminals, when it is transmitted, it will be electromagnetic interference between each other. The noise or signal transmission is incomplete. Therefore, some of the electrical connectors also have a shield embedded in the insulating body, and the shielding member is used to provide electromagnetic shielding effect to improve the quality of signal transmission.

Currently, the electrical connector structure includes an insulative housing, a first terminal set, a second terminal set, a shield, and a metal housing. The insulating system is assembled by a first insulator and a second insulator, and a base portion and a tongue plate extending forwardly are formed, and the first terminals of the first terminal group are respectively arranged at intervals. The second terminal of the second terminal group is spaced apart from the bottom surface of the second insulator, and the shielding member is butted through the first insulator and the second insulator. Covered between them, and finally wrapped around the outside of the insulating body with the metal casing around the space.

However, the shield used in the electrical connector has a ground terminal structure that is generally inelastic, which is not easy to provide a stable contact and has a poor grounding effect, and the first ends are The second terminal and the ground terminal are also susceptible to slight misalignment or deformation during assembly, resulting in poor contact; in addition, since the grounding path of the shield is generally limited, it is difficult to provide good The grounding effect is therefore necessary to improve.

Furthermore, since the first terminals of the electrical connector, the second terminals, and the grounding terminals of the shield are all arranged in a plurality of rows arranged in parallel along the rear, when welding, it is necessary to perform welding. The outer periphery of the downwardly bent extension is pre-coated with an insulating material to avoid deformation thereof, thereby increasing the spacing of the adjacent two rows requiring welding, resulting in the insulative body of the electrical connector from the front end face of the base to the rear The space occupied by the end faces becomes large, which is not conducive to the miniaturization of electronic products.

In view of this, one of the purposes of the present invention is to provide an electrical connector structure in which a first terminal set, a grounded metal plate and a second terminal set are sequentially arranged by means of insert molding, and integrally formed. The coating is disposed inside an insulating body, thereby achieving the effect of simplifying the assembly process and reducing the manufacturing cost.
