specific Embodiment

[0030] like Figure 1a , 1b , shown in 1c: the cable joint of the present invention is covered by a set of aluminum alloy casing as a whole, and is made up of tailpipe 2, casing 3 and base 4, and each other is fastened and connected by fastener 14, in order to prevent the contact surface seepage, in A sealing ring 13 is designed on the contact surface of the tail pipe 2 and the shell 3, and a sealing gasket 17 is designed on the contact surface of the shell 3 and the base 4 for protection. Ensure that the overall protection level requirements of IP66 are met.

[0031] like figure 2 As shown: the main body of the cable joint of the present invention is composed of a main insulating layer 7, a conductive rod 6, a voltage equalizing shielding layer 5 and a sprayed semi-conductive layer 15, and the shape of the main insulating layer 7 matches the shape of the shell 3 to play The role of fixing the main body of the joint is limited by the processing accuracy or manufacturing lev...

Abstract

The invention discloses a cable connector applied to a rolling stock. The cable connector comprises a shell, a base and a tail pipe, and a cable connector body is arranged in the cable connector. Thetail end of the tail pipe is connected with a cable through a thermal shrinkage sealing pipe; the cable connector body comprises a body insulating layer, a semi-conductive layer is sprayed on the outer wall of the body insulating layer, a conductive rod is arranged in the body insulating layer, and a voltage-sharing shielding layer wraps the outer wall of the conductive rod. Plugging terminals arearranged at the two ends of the cable connector respectively, the front ends of the plugging terminals are connected with a cable in a pressed mode through high-voltage terminals, and a stress control body is arranged at the rear ends of the plugging terminals and connected with a shielding layer stripped and cut off from the cable in a lap joint mode. A spring and pressing pipe group is arrangedbetween the plugging terminal and the tail pipe. The cable connector is used for being connected with high-voltage cables of a straddle carrier, the two high-voltage cables are connected through cooperation of the plugging terminals and the connector body, the flow guide and insulation effects are achieved, meanwhile, the insulation performance and the protection grade of the connector can be considered and guaranteed, and the use requirement of a motor train unit can be met.

Description

technical field [0001] The invention relates to a cable accessory for locomotives, in particular to a cable joint applied to locomotives. Background technique [0002] With the development of rail transit technology and the continuous improvement of the operating speed of EMUs, there are higher and higher requirements for the aerodynamic shape of EMUs. For grid-side high-voltage electrical appliances, it has become a trend that fewer and fewer parts are exposed to the outside of the vehicle. High-voltage cables, as the transmission channel between the pantograph and the on-board transformer, must also be laid according to the preset pipeline. At the same time, considering the EMU manufacturing And during maintenance, each marshalling vehicle is an independent component, and the high-voltage cables straddling the vehicle are not easy to install, dismantle, and maintain, and the cable intermediate joint is a necessary component. [0003] The cable joint is used to connect the...
