Description

[0002] With the rapid development of science and technology, the transmission rate of signals between interfaces of various electronic products has always been a key research and development project. Therefore, the early transmission rate has increased from 1.5Mbps of USB1.0 to the highest 20Gbps of USB3.2 in recent years, and even the new USB4 can be increased to 40Gbps. The higher the speed of the connector, the higher the anti-interference ability required.

[0003] In order to improve the anti-interference ability of the connector, a shielding shell and a shielding sheet are usually provided, and the shielding sheet and the shielding shell are connected to improve the anti-interference ability. However, due to the overly complex connection structure between some shielding sheets and the shielding shell, the assembly is difficult and the connector cost increases.

[0004] For example, the electrical connector and the cable connector having the electrical connector disclosed in Chinese patent application number: CN201410331375.6 specifically disclose that "a shielding sheet separates two sets of conductive terminals respectively arranged on the first module and the second module, and the shielding sheet can be electrically connected to the shielding member on the docking connector through a conductive buckling element". Two additional conductive buckling elements are arranged on both sides of the insulating shell, and the conductive buckling elements need to be connected to the shielding sheet. Therefore, the conductive buckling elements increase the number of accessories, making the structure complicated. The conductive buckling elements also need to be connected to the shielding sheet, making the structure complicated, increasing the difficulty of assembly, and increasing the manufacturing cost.

The first injection molding module 10 and the second injection molding module 20 are injection molded parts, and both are first molded by injection molding. A plurality of first terminals 12 are injection molded in the first injection molding module 10, and a plurality of second terminals 21 are injection molded in the second injection molding module 20. Among them, the first terminal 12 and the second terminal 21 are slightly arched inwardly, so that the contact ends of the first terminal 12 and the second terminal 21 will obtain a certain elastic force and the contact quality will be better. The shielding member 30 is preferably formed in one piece by a stamping process, and its structural stability is good, the number of accessories is reduced, the contact quality is guaranteed, and it is beneficial to cost reduction.

[0034] The shielding member 30 includes a main body 31 and a conductive part 33 formed on the left and right sides of the main body 31; the conductive part 33 has a protrusion 34 protruding outward; the first insulating body 40 includes a base part 41 and a tongue part 42; the conductive part 33 wraps the base part 41 and is exposed in the first groove 43 of the tongue part 42. The main body 31 in this embodiment is plate-shaped, and the protrusion 34 extends from the left and right sides of the main body 31 and is formed after bending. After the first injection mold 10 and the second injection mold 20 are inserted into the first insulating body 40, the conductive part 33 is bent and wrapped around the base part 41, so that the first injection mold 10, the second injection mold 20, and the first insulating body 40 are firmly assembled together, and at the same time, part of the conductive part 33 is exposed in the first groove 43 of the tongue part 42, so that it is convenient for the conductive part 33 to be connected and conducted with the first shielding shell 50.

[0035] The first shielding shell 50 wraps the first insulating body 40 and is buckled on the first injection mold 10 and the second injection mold 20; the protrusion 34 is embedded in the first hole 51 on the first shielding shell 50. When the first shielding shell 50 and the first insulating body 40 are assembled, the first shielding shell 50 wraps the tongue plate portion 42 of the first insulating body 40 and is buckled on the first injection mold 10 and the second injection mold 20, so that the first shielding shell 50, the first insulating body 40, the first injection mold 10, and the second injection mold 20 are firmly assembled together. At the same time, the protrusion 34 is embedded in the first hole 51 on the first shielding shell 50, which further improves the assembly firmness of the first shielding shell 50 and the first insulating body 40, and also allows the conductive part 33 of the shielding member 30 to be connected with the first shielding shell 50 to ensure the shielding performance. It can be seen that the improved shielding member 30 realizes the conductive grounding of the shield, reduces the number of accessories, and the cost will be lower.

When the second shielding shell 60 and the third shielding shell 70 are snapped together, they can wrap the base part 41, as well as the first injection mold 10 and the second injection mold 20. There is a certain overlap between the first shielding shell 50 and the second shielding shell 60 and the third shielding shell 70, so the first shielding shell 50, the second shielding shell 60, the third shielding shell 70, and the shielding member 30 are conductive. Therefore, under the joint shielding action of the first shielding shell 50, the second shielding shell 60, the third shielding shell 70, and the shielding member 30, the connector is shielded in all directions.

[0042] Preferably, the third shielding shell 70 is bent to form a grounding pin 74; the grounding pin 74 is connected to the connecting piece 62 extending from the back of the second shielding shell 60. The grounding pin 74 and the connecting piece 62 can be connected together by crimping, welding, riveting, etc. After the grounding pin 74 and the connecting piece 62 are connected together, the first shielding shell 50, the second shielding shell 60, the third shielding shell 70, and the shielding member 30 can share the grounding pin 74, which is very convenient.
