Problems solved by technology

[0002] The structure of the metal terminal used in the current Fakra connector is generally integrated, that is, the shrapnel in contact with the external connection terminal and the metal end fixed to the insulating seat of the connector are integrated, such as figure 1 As shown, when connecting with an external connector, the male pin of the external connector is inserted between several shrapnels, and the male pin is fixed by the stress generated by several shrapnels on the male pin; and the shrapnel of this type of connector is generally relatively small in size , Thin, so its own elastic force is not large, the stress that can be generated on the male pin is relatively small, so it is easy to appear that the connection of the male pin is not stable enough, resulting in unstable electrical contact performance between the two connectors, affecting Stability of data transmission between two connectors

Embodiment 1

[0037] This embodiment provides a stable signal connector, such as Figure 2 to Figure 8 As shown, it includes a plastic seat 12, a metal outer cylinder 13 inserted in the plastic seat 12, an insulating seat 14 disposed in the metal outer cylinder 13, and a metal terminal assembled in the insulating seat 14. The metal outer cylinder 13 1. The insulating seat 14 and the metal terminal are arranged coaxially. The plastic seat 12 is provided with a docking hole 15. The front ends of the metal outer cylinder 13, the insulating seat 14 and the metal terminal are all exposed in the docking hole 15. The metal terminal includes The metal sleeve 1 and the claw spring 2, the claw spring 2 is used to clamp the external connection terminal, the metal sleeve 1 is provided with a cavity 3, and the claw spring 2 is assembled in the cavity 3; The claw spring 2 includes a support portion 4 and a clamping portion connected to the support portion 4 , and the outer periphery of the support portio...

Embodiment 2

[0050] This embodiment provides a stable signal connector, such as Figure 14 , Embodiment 2 On the basis of Embodiment 1, the outer wall of the insulating seat 14 is provided with axial ridges 18, and the outer walls of the upper insulating part 16 and the lower insulating part 17 are provided with a number of axial ridges 18. The axial ridges 18 are arranged at equal intervals, and the axial ridges 18 are arranged along the axial direction of the upper insulating portion 16 and the lower insulating portion 17 . Specifically, the high-frequency performance of this embodiment can be improved by providing the axial convex strips 18 with intervals between them.

Embodiment 3

[0052] This embodiment provides a stable signal connector, such as Figure 15 , Embodiment 3 On the basis of Embodiment 1, transverse ribs 19 are set on the outer wall of the insulating seat 14, and the outer walls of the upper insulating part 16 and the lower insulating part 17 are protrudingly provided with several transverse ribs 19, and several transverse ribs 19 are provided. The strips 19 are arranged at equal intervals, and the transverse convex strips 19 are arranged along the circumference of the upper insulating portion 16 and the lower insulating portion 17 , that is, the transverse convex strips 19 are arranged coaxially with the upper insulating portion 16 and the lower insulating portion 17 . Specifically, the high-frequency performance of this embodiment can be improved by arranging the transverse ribs 19 with intervals between the transverse ribs 19 .

Abstract

The invention relates to the technical field of connectors, and particularly relates to a stable-signal connector which comprises a plastic seat, a metal outer cylinder inserted in the plastic seat, an insulating seat arranged in the metal outer cylinder and a metal terminal assembled in the insulating seat. A pawl spring of the metal terminal is separated from a metal sleeve, the pawl spring is assembled in the metal sleeve, the pawl spring and the metal sleeve are in interference fit to form hard interference, and the hard interference enables a larger positive force to be generated between the metal sleeve and the pawl spring so that the pawl spring can be fixed, the stress of the elastic sheet on the external connection terminal can be increased through the positive force generated by the hard interference, the connection stability of the external connection terminal is improved, and the stability of electric contact between the elastic sheet and the external connection terminal is increased. Therefore, when the metal sleeve and the elastic sheet are manufactured, a valuable metal coating can be prevented from being adopted to improve the electrical connection performance, and the manufacturing cost can be reduced.
