Floating signal contact element and electric connector using the same

Abstract

The invention discloses a floating signal contact element and an electric connector using the same. The contact comprises an inner conductor and an outer conductor. A stop collar between a first axiallimit structure and a second axial limit structure on the outer wall of the outer conductor is provided with a spring and a sliding bush glidingly matched with the outer wall of the outer conductor;the sliding bush is assembled between the spring and the second axial limit structure in the mode of axial spacing; the outer wall of the sliding bush is provided with an elastic radial actuating structure and a third axial limit structure which are clamped on the shell of an adaptive connector; the elastic radial actuating structure and the third axial limit structure are relatively arranged, andan intake limit space for the convex part of the shell to enter is formed between the elastic radial actuating structure and the third axial limit structure. The outer conductor of the signal contactelement realizes the detachable assembly between the outer conductor and the shell of the connector through the sliding bush sheathed on the outer conductor and matched with the spring in the mode ofaxial limit, the elastic radial actuating structure on the sliding bush can be clamped on a corresponding structure in the shell of the connector to be in limit match or to be fixed together when being expanded, and can be frapped by a detaching tool to realize separation.

Description

technical field [0001] The invention relates to the technical field of electrical connectors. Background technique [0002] Existing electrical connectors for radio frequency signal transmission generally include a housing and signal contacts installed therein, and the signal contacts include an outer conductor and an inner conductor fixed in the outer conductor through an insulator. The outer conductor of the existing signal contact It is generally fixedly assembled with the housing of the electrical connector. In order to make the signal contact have a certain impact resistance, a spring is installed between the outer conductor and the housing of some signal contacts to achieve relative movement.

[0002] Existing electrical connectors for radio frequency signal transmission generally include a housing and signal contacts installed therein, and the signal contacts include an outer conductor and an inner conductor fixed in the outer conductor through an insulator. The outer conductor of the existing signal contact It is generally fixedly assembled with the housing of the electrical connector. In order to make the signal contact have a certain impact resistance, a spring is installed between the outer conductor and the housing of some signal contacts to achieve relative movement. Due to various Due to the difference in the size of the shell structure of the connector, the matching structure between the existing signal contact and the shell is relatively complicated, it is difficult to assemble and disassemble, and the volume is large, which makes it difficult to manufacture such signal contacts as standard parts and cannot adapt to connection.
