Embodiment 1

[0042] Such as figure 1 , the shielded electrical connector of this embodiment is formed by sintering a metal shell, a solder cup pin, a glass blank, a ceramic base a, and a ceramic base b, and then a spiral shielding ring 6 and an O-ring 7 are installed to form an electrical connector. The connector as a whole. The stepped flange 101 is used as a force-bearing end and can withstand a pressure of 170MPa. The solder cup pins of the electrical connector do not expose the top of the guide ring 102, and the guide ring 102 serves to protect the solder cup pins 2 to prevent damage to the solder cup pins 2 during docking. The O-ring groove 105 is used for installing the O-ring 7 to play a sealing role. The design of the two O-ring grooves 105 can effectively shield the exchange of gas and liquid at both ends of the electrical connector of the present invention.

[0043] The shielding tube adopts a symmetrical design. One end of the shielding tube is connected to the metal shell, an...

Embodiment 2

[0064] On the basis of Embodiment 1, when the present invention is applied to a 35-core shielded connector, 35 pin holes are provided in the cylindrical housing, one of the 35 pin holes is coaxially arranged with the cylindrical housing, and the rest The 34 pin holes are divided into the first group, the second group and the third group according to the number of 5, 14, and 15. Each group of pin holes is arranged on a circle coaxial with the cylindrical shell. The first group 1. The diameters of the circles where the second and third groups of pin holes are located increase sequentially, and the diameter of the shielding ring is larger than the diameter of the circle where the first group of pin holes is located, and smaller than the diameter of the second group of pin holes.

[0065] refer to image 3 , The metal shell of the 35-core shielded electrical connector is provided with a total of 35 pin holes, bounded by the circumference of the shielding tube 7, and the pin holes ...

Abstract

The invention discloses a multi-core shielded electric connector which comprises a shell, two shielding pipes, a plug pin component and shielding rings. The shell comprises a columnar shell body, a step flange is arranged on the periphery of a primary pressure-bearing end of the columnar shell body, a guide ring is arranged on the periphery of a secondary pressure-bearing end of the columnar shellbody, a plurality of plug pin holes are formed in the columnar shell body, the two shielding pipes are centrosymmetric about the columnar shell body and connected on the primary pressure-bearing endand the secondary pressure-bearing end, a shielding ring groove is formed in the inner annular periphery of one end of each shielding pipe facing to the shell body, a thread for connecting with an external device is arranged at the other end of each shielding pipe, the periphery of axial projection of each shielding pipe on the columnar shell body serves as a boundary, more than one plug pin holeis formed inside and outside each periphery of the projection, the plug pin component comprises an annular plug pin base and a plug pin, the annular plug pin base penetrates the plug pin hole, one endof the plug pin penetrates the outer end surface of the step flange, the length of the other end of the plug pin positioned the columnar shell body is smaller than the axial length of the guide ring,and the shielding rings are embedded into the shielding ring grooves. The multi-core shielded electric connector is high in electromagnetic interference resistance and can meet transmission requirements of signals in strong low-frequency environments.

Description

technical field [0001] The invention relates to a multi-core electromagnetic shielding electrical connector, in particular to a shielding electrical connector working in a strong low-frequency electromagnetic field or a high temperature and high pressure environment, which is used for signal transmission in special working conditions. Background technique [0002] At present, with the development of electronic components, many types of electrical connectors have been derived, and these electrical connectors are widely used in different fields. As a connection and transfer device for electrical signals, electrical connectors are especially important for their electromagnetic shielding structure to have signal transmission stability and electrical stability, which reduces noise interference, ensures signal transmission quality, and is conducive to signal analysis of transmitted data. Electrical connectors are mainly divided into rectangular structure and circular structure. Th...
