Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a double-layer connector with a shielding structure. Background Art

[0002] A connector is also called a plug. In China, it is also called a connector and a socket, generally referring to an electrical connector. That is, a device connecting two active devices, transmitting current or signals. The male end and the female end can transmit messages or current after contact, and it is also called a connector. The basic performance of a connector can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance is the mechanical life of the connector. The mechanical life is actually a durability index, which is called mechanical operation in the national standard GB5095. It takes one insertion and one extraction as a cycle, and whether the connector can normally complete its connection function (such as the contact resistance value) after the specified number of insertion and extraction cycles is used as the evaluation basis.

[0003] The existing double-layer connector uses an external shielding case in its structure to prevent external signal crosstalk. However, during the signal transmission process between the upper and lower layer terminals and between the horizontally adjacent terminals, crosstalk still occurs, thus affecting the overall transmission process of the connector. Its shielding effect is not good only with the structure of the shielding case, and it cannot solve the problem of internal crosstalk, affecting the stability of the internal signal transmission process of the connector. Therefore, it is necessary to further improve the existing connector structure. Summary of the Utility Model

[0031] Please refer to Figures 1 to 6 As shown, it shows the specific structure of the preferred embodiment of the present utility model, which includes an insulating body 10, a terminal group 20, a shielding case 30, a first shielding member 40, and a second shielding member 50.

[0032] The front end face of the insulating body 10 is integrally recessed inward to form an insertion cavity 101. The insertion cavity 101 is arranged in two layers up and down, and each layer includes a plurality of insertion cavities 101 arranged horizontally at intervals. In this embodiment, an insulating tape 11 is attached to the rear end face of the insulating body 10, and the insulating tape 11 is clamped between the insulating body 10 and the shielding case 30, so as to prevent the part of the device arranged in the insulating body 10 that exposes the rear end face of the insulating body 10 from contacting and short-circuiting with the shielding case 30.

[0033] The terminal group 20 is embedded in the insulating body 10. A plurality of terminal groups 20 are provided. The welding part of each terminal group 20 extends inward into the corresponding insertion cavity 101, and the welding part of the terminal group 20 extends out of the insulating body 10 and is connected to the outside. In this embodiment, the contact parts 21 of the two terminal groups 20 located in the upper and lower insertion cavities 101 are arranged at intervals up and down, and their welding parts 22 are arranged at intervals front and back.

[0034] The shielding case 30 is sleeved on the outer surface of the insulating body 10 and is connected to the outside; in this embodiment, a pin 31 connected to the outside extends integrally downward from the lower end face of the shielding case 30. The shielding case 30 is connected and conducted to the outside through the pin 31, so as to achieve the shielding effect.

[0035] The first shielding members 40 are multiple arranged horizontally at intervals. Each first shielding member 40 is arranged in the insulating body 10 and is located between the upper and lower insertion cavities 101. All the first shielding members 40 are conducted with the shielding case 30, so as to achieve the signal shielding effect between the two terminal groups 20 in the upper and lower insertion cavities 101. In this embodiment, the first shielding member 40 includes a first main body part 41 extending horizontally and a second main body part 42 extending vertically. The first main body part 41 is clamped between the contact parts 21 of the two terminal groups 20; the second main body part 42 is clamped between the welding parts 22 of the two terminal groups 20, so as to make the shielding effect better. Elastic pieces 43 extend integrally outward from the left and right sides of the first shielding member 40. The elastic pieces 43 on the first shielding member 40 located inside are in contact and conduction with the adjacent first shielding member 40, and the elastic pieces 43 on the first shielding member 40 located outside are in contact and conduction with the shielding case 30, so as to achieve that all the first shielding members 40 are in contact and conduction with the shielding case 30.

[0036] The second shielding member 50 is disposed in the insulating body 10. A plurality of the second shielding members 50 are arranged at lateral intervals. Each second shielding member 50 is disposed between two laterally adjacent terminal groups 20. Each second shielding member 50 is electrically connected to the shielding case 30, so as to achieve the shielding effect between two laterally adjacent terminal groups 20. Through the cooperation of the first shielding member 40 and the shielding case 30, it can not only shield the crosstalk of external signals, but also shield the signal crosstalk between two internally adjacent terminal groups 20, and the overall signal shielding effect is better. In this embodiment, the second shielding member 50 includes an installation portion 51 and a shielding portion 52. The shielding portion 52 is partially inserted into the installation portion 51 from front to back, and the rear end of the shielding portion 52 protrudes backward from the installation portion 51 to form a connection portion 521. The adjacent first shielding members 40 are respectively in contact with the connection portion 521 through elastic pieces 43, so as to achieve the electrical connection between the second shielding member 50 and the first shielding member 40, and the electrical connection between the second shielding member 50 and the shielding case 30. The upper and lower side walls of the second shielding member 50 are respectively located above the terminal group 20 in the upper insertion cavity 101 and below the terminal group 20 in the lower insertion cavity 101, so that the shielding effect between the upper and lower two-layer terminal groups 20 can be achieved only by one second shielding member 50, and the structure is simpler.
