[0011] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0012] like Figure 1 、 Figure 2 The double-wire fixed electrical connection device shown is installed in the wind zone arm system of the high-speed electrified railway contact network system, and has an arm frame 1, a load-bearing cable 3 is fixed to the upper end of the arm frame 1, a contact wire 4 is fixed to the lower end of the arm frame 1, and a positioning tube 2 is fixed in the middle of the arm frame 1.

[0013] A first electrical connection line 5 is provided on the left side of the positioning tube 2, and a second electrical connection line 6 is provided on the right side of the positioning tube 2. The upper ends of the first and second electrical connection lines 5 and 6 are respectively secured to the Messenger cable using a Messenger cable electrical connection line clamp 8. The lower ends of the first and second electrical connection lines 5 and 6 are respectively secured to the contact wire 4 using a contact wire electrical connection line clamp 9. The Messenger cable electrical connection line clamp 8 consists of a clamp body and a pressure block, which are crimped and fixed on site. The contact wire electrical connection line clamp 9 consists of a clamp body and a threaded clip, which are installed and fixed on site.

[0014] The positioning tube 2 is provided with a transition clamp 7, which includes a clamping plate 7-1 and a wire pressing plate 7-2. The intermediate portions of the clamping plate 7-1 and the wire pressing plate 7-2 are clasped on the positioning tube 2 and fixed by fastening bolts.

[0015] The utility model optimizes the structure of the existing electrical connection device by setting two electrical connection lines between the load-bearing cable 3 and the contact line 4 to improve the electrical performance of the arm-cantilever system. When one electrical connection line breaks or fails in other ways, the electrical performance of the arm-cantilever system at that position can still be maintained, thereby improving the stability and reliability of the contact network system.

[0016] Fixing the two electrical connection wires to the positioning tube 2 through the transition wire clamp 7 can reduce the up and down shaking and left and right swinging of the electrical connection wires caused by external interference factors, thereby reducing the irregular stress on the electrical connection wire clamp and extending the service life of the electrical connection wire clamp.
