Embodiment Construction

[0024] The present invention will be further described below in conjunction with drawings and embodiments.

[0025] Figure 1-3 As shown, a Y63 series high-speed rail special electrical connector includes a front housing 1, a rear housing 2, a front insulator 3, a rear insulator 4, a circular contact piece 5, a spacer body 6, a screw 7, and a rotary pressure head 8 And cable end clip 10. The front insulator 3 is connected to the outer port of the front housing 1 by integral injection molding. The inner wall of the front housing 1 is provided with an axial anti-mis-insertion key 14, and the rear insulator 4 is matched with the anti-mis-insertion key through the anti-mis-insertion key groove 41 on its outer periphery. 14 is plugged into the front housing 1, the front end of the rear insulator 4 is connected with more than two circular contacts 5 passing through the front insulator 3, and the rear end of the rear insulator 4 is connected with a spacer connecting wires connecting...

Abstract

The invention relates to an Y63-series special-type electric connector for high-speed rails, comprising a shell, an insulator and circular contact elements. The shell comprises a front shell and a back shell, the insulator comprises a front insulator and a back insulator, the front insulator is arranged in the front shell, more than one circular contact element is connected to the back insulator,and the back shell presses out the back insulator between the front shell and the back shell so that the part of more than one circular contact element, which is over the back insulator, is arranged in the front insulator. The front shell and the back shell are connected in series with the front insulator and the back insulator by central screw assemblies to form an electric connecting line with a vertical outside-line opening, and the circular contact elements with hermaphroditic structures, which are inserted on the back insulator, are matched, thus the electric connector has the advantagesof simple and compact structure, stability and firmness in connection, good sealing performance, high switched-on power performance and high safety, and is suitable for train control system responderunits of high-speed rails, underground railways and the like.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a special electrical connector used for transponder units of train control systems such as high-speed railways and subways. Background technique [0002] High-speed railway is a new mode of transportation in modern society. The speed of China's high-speed railway represents the current speed of the world's high-speed railway. The country with the highest operating speed and the largest scale under construction, in the next 30 years, my country will plan to connect the major provinces and cities in the country to form a national high-speed rail framework with five vertical, six horizontal and seven lines. Therefore, high-speed railways have very high safety requirements for trains. In the train control system, cables and connectors are often used to connect electronic equipment. All cannot meet the long-term use of the train in a strong vibration state, and it is urgent to improve th...
