Problems solved by technology

[0004] The currently used connection joints have certain defects, such as the lack of extrusion function for the fixed joints, resulting in easy loosening of the cylinder, poor connection between the fixed joints and the plug, and affecting the quality of signal transmission. At the same time, the lack of protective mechanisms makes it easy for moisture to enter through the bearings inside the plug, thereby affecting signal transmission

Embodiment 1

[0043] In this embodiment, an example is used for illustration, but it does not mean that the connection joint provided by the present invention is only suitable for the signal receiver of the EMU. It can also be applied to signal receivers of other devices according to different specific scenes or objects.

[0044] refer to Figure 1-3 As shown, a connection joint includes a fixed joint 1, a plug 2, a cylinder 3, and a pipe fitting. One end of the fixed joint 1 is plugged with a plug 2, and a pipe fitting is installed at the rear end of the plug 2. cylinder 3, and the cylinder 3 is installed on the outside of the plug 2, bearings are installed on the annular side of the pipe fitting, and the outer side of the bearing is fixedly installed inside the cylinder 3, and the data line is installed inside the pipe fitting, and the data line is electrically connected to the plug 2 Connection, when in use, insert one end of the plug 2 into the fixed joint 1, so that the metal core ins...

Embodiment 2

[0058] Based on the connecting joint of Embodiment 1, a signal receiver is disclosed. The signal receiver is connected to the external signal transmission line through the connecting joint. on-line.

Embodiment 3

[0060] Based on the signal receiver of the second embodiment, a complete vehicle is disclosed, and the complete vehicle uses the signal receiver to receive external signals.

[0061] The whole vehicle can be an EMU, or other locomotives such as trains or passenger cars.

Abstract

The invention provides an attachment joint, a use method, a signal receiver and a whole vehicle, the attachment joint comprises a fixed joint, a plug and an extrusion mechanism; the fixed joint is inserted into one end of a plug, a pipe fitting is mounted at the other end of the plug, and a cylinder is mounted on the annular side surface of the pipe fitting; and an extrusion mechanism is arranged at the rear end of the cylinder and feeds back an axial force of the cylinder when the fixed joint enters the cylinder and the plug is movably inserted along the cylinder, so that the cylinder is prevented from automatically rotating.

Description

technical field [0001] The invention belongs to the technical field of connecting joints, and in particular relates to a connecting joint, a use method, a signal receiver and an EMU. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The signal receiver usually has two cores: 8187L chip and Ralink 3070 chip. The signal receiver is connected to the external signal transmission line through the connection joint. One end of the fixed joint is fixedly installed on the signal receiver, and the plug is fixedly installed on the external signal transmission line. It is convenient for signal transmission and connection. [0004] The currently used connection joints have certain defects, such as the lack of extrusion function for the fixed joints, resulting in easy loosening of the cylinder, poor connection between the fixed joints and the plug, and a...
