Embodiment Construction

[0009] Attached below figure 1 The present invention is further described.

[0010] as attached figure 1 As shown, a device for realizing joint signal transmission is mainly composed of an insulating sleeve 1 , a conductor rod 2 , a spring 3 , and a conductor ring 4 . First process the axial holes at the joints of the two joints respectively, install the insulating sleeve 1, the conductor rod 2 and the conductor ring 4 in the axial holes respectively, the conductor rod 2 is set in the inner cavity of the insulating sleeve 1, and the insulating sleeve 1 can hold the conductor rod 2 and the conductor ring 4 are not in contact with the joint, and the inner cavity of the insulating sleeve 1 is processed into a step shape, and the outer surface of the conductor rod 2 is also processed into a step shape. A spring 3 is installed in the annular space, and the spring 3 can keep the conductor rod 2 and the conductor ring 4 in a contact state all the time, and the conductor rod 2 is re...

Abstract

The invention provides a device for realizing joint signal transmission which is mainly composed of an insulation covering (1), a conductor bar (2), a spring (3) and a conductor ring (4). An axial hole is in combining part of two joints, and the insulation covering (1), the conductor bar (2), the spring (3) and the conductor ring (4) are installed in the axial hole respectively, the conductor bar(2) is covered installed in inner cavity of the isolation covering (1), the insulation covering (1) prevents the conductor bar (2) and the conductor ring (4) from contacting with joint, the insulation covering (1) has step inside, the conductor bar (2) has step on exterior surface, the insulation covering (1) inner cavity step and the conductor bar (2) exterior surface step are installed with spring (3), and keep contact state with the conductor bar (2) and conductor ring (4), the conductor bar (2) connects with signal transmission wire respectively, thereby, signal transmission of joint can be realized.

Description

technical field [0001] The invention relates to an underground signal transmission tool in the petroleum industry, in particular to a device for realizing joint signal transmission. Background technique [0002] Since the signal transmission line is easily entangled or even broken during the buckle-up process of the joint, the signal transmission of the joint has always been a problem. Due to the limited size of the joint step surface, there is not enough space to install the insulating ring and the conductor ring. Contents of the invention [0003] The present invention aims to provide a device capable of realizing joint signal transmission under the condition that the size of the step surface of the joint is limited. [0004] The present invention is mainly composed of an insulating sleeve 1, a conductor rod 2, a spring 3, and a conductor ring 4. Axial holes are respectively processed at the joints of the tool, and the insulating sleeve 1, the conductor rod 2 and the co...
