Description

Technical Field

[0001] The present invention relates to a connector, in particular to a socket electrical connector for improving process efficiency. In the batch process of the socket electrical connector, a plurality of shielding plates are connected by a material strip and a plurality of terminal groups and a plurality of insulating bodies are simultaneously fixed to the corresponding shielding plates by injection molding, thereby improving productivity. Background Art

[0002] Electrical connectors are common electronic components on electronic devices, which can be connected to matching electrical connectors on other electronic devices to transmit signals and power between the two electronic devices. Existing electrical connectors include Universal Serial Bus (USB) 3.1 electrical connectors. The USB 3.1 protocol has added the Type C electrical connector specification, which not only provides an ultra-high-speed data transmission rate of 10Gbps, but is also thin and small in size and suitable for portable devices such as mobile phones. The plug interface is symmetrical and can be plugged in either direction, so it can be widely used in various electronic devices.

[0003] The aforementioned USB Type C socket electrical connector has an insulating body, two sets of conductive terminals and a metal shell. The insulating body is made of plastic and has a tongue protruding from it. In addition, a metal sheet is embedded in the insulating body by injection molding to serve as a reinforcement of the tongue. The two sets of conductive terminals are arranged on the tongue of the insulating body to transmit signals. The metal shell covers the insulating body and the two sets of conductive terminals.

[0004] However, when the injection molding process is implemented to fix the insulating body on the metal sheet, the insulating body is injected and fixed to each individual metal sheet. When the insulating body is mass-produced, a single device cannot inject and fix multiple insulating bodies to multiple metal sheets at the same time, but the metal sheets must be injection molded sequentially. Therefore, it is difficult to mass-produce the socket electrical connector efficiently. Summary of the invention

[0005] In view of the fact that the existing socket electrical connector cannot simultaneously perform injection molding of a large number of metal sheets and an insulating body, the inventor improves the insufficiency and defects thereof and further invents a socket electrical connector with improved process efficiency.

[0006] The main purpose of the present invention is to provide a socket electrical connector that improves process efficiency, wherein in the batch process of the socket electrical connector, a plurality of shielding plates are connected by a material strip and a plurality of terminal groups and a plurality of insulating bodies are simultaneously fixed to the corresponding shielding plates by injection molding, thereby improving productivity.

[0007] To achieve the above-mentioned purpose, the socket electrical connector for improving the process efficiency comprises: an insulating fixing seat, which has a base and a tongue, and the tongue protrudes from the front of the base; a first terminal group, which is arranged on the insulating fixing seat and includes a plurality of first terminals, and the front end of each of the first terminals forms a first electrical contact section arranged on the bottom surface of the tongue of the insulating fixing seat; a second terminal group, which is arranged on the insulating fixing seat and includes a plurality of second terminals, and the front end of each of the second terminals forms a second electrical contact section arranged on the top surface of the tongue of the insulating fixing seat, wherein the first terminal group and the second terminal group are point symmetrical to each other with the center point of the tongue as the symmetry center; a shielding plate, which is embedded in the insulating fixing seat and embedded in the tongue of the insulating fixing seat, and a connecting portion is formed on both sides of the shielding plate, and a material strip cutting surface is formed on each connecting portion, and the two material strip cutting surfaces are respectively exposed on both sides of the tongue; and a shielding shell, which has a plug-in space formed thereon to accommodate the insulating fixing seat, the first terminal group and the second terminal group.

[0008] By means of the above technical means, the shielding plate is integrally formed with a metal strip by a strip cutting surface during the manufacturing process. The strip may have a connecting plate and a plurality of connecting arms. The plurality of shielding plates are simultaneously connected through the plurality of connecting arms, and the strip may be fixed on a fixing device. In the batch production process of the socket electrical connector, the insulating fixing seat includes an inner insulating body and an outer insulating body. First, a plurality of first terminal groups are matched and positioned with the plurality of shielding plates. Then, an injection molding device is used to simultaneously perform a first injection molding process on the plurality of shielding plates and the plurality of first terminal groups to simultaneously form a plurality of inner insulating bodies. Then, a plurality of second terminal groups are matched and positioned with the inner insulating body. Then, a second injection molding process is performed to simultaneously form a plurality of second outer insulating bodies outside the corresponding inner insulating body and the second terminal group. Finally, a cutting tool is used to cut off the connection between the shielding plate and the strip. At this time, the strip cutting surface is formed on both sides of each shielding plate. By integrally forming and connecting a plurality of shielding plates on a single strip, the injection molding operations of a plurality of inner insulating bodies and an outer insulating body can be completed simultaneously, thereby greatly shortening the injection molding time and achieving the purpose of batch manufacturing of socket electrical connectors in a short time.

[0009] The aforementioned insulating fixing seat includes an inner insulating body and an outer insulating body. The outer insulating body is arranged on the inner insulating body, and the base and the tongue are formed on the outer insulating body.

[0010] The two connecting parts of the shielding plate are respectively formed at the center of both sides of the shielding plate.

[0011] Both sides of the shielding plate protrude outwards near the front end to form a corner reinforcement element.

[0012] The two sides of the aforementioned shielding plate protrude outward from the front end to form a corner reinforcement element, and the two connecting parts are respectively formed on the outer sides of the two corner reinforcement elements. The two material strip cut surfaces are respectively formed on the two connecting parts of the two corner reinforcement elements and are respectively exposed at the front ends of the two sides of the tongue.

[0013] The first terminal group and the shielding plate are arranged on the inner insulating body by a first injection molding method.

[0014] After being combined, the first terminal set, the shielding plate, and the inner insulating body are further arranged on the outer insulating body by a second injection molding method.

[0015] The aforementioned socket electrical connector further comprises a protection cover, which is arranged on the shielding shell, and a fixing foot protrudes downwards on both sides of the protection cover. BRIEF DESCRIPTION OF THE DRAWINGS
