Abstract
A high-voltage output safety joint comprises an insulation sleeve. The upper end of the insulation sleeve is fixedly connected with a fixing seat sleeve in a thread matching mode. The upper end of the fixing seat sleeve is connected with a wire output protection sleeve of an output cable in a thread matching mode. The lower end of the insulation sleeve is connected with an inner guide wire connection joint in a thread matching mode. An output cable connection joint, a spring and an insulation pressing pipe are arranged in the insulation sleeve in sequence from bottom to top. An outer flange is arranged at the upper end of the insulation pressing pipe. The outer flange is arranged between the upper end face of the insulation sleeve and the wire output protection sleeve of the output cable in a clamping mode. The upper end face of the inner guide wire connection joint is matched with the output cable connection joint in a contacting mode. A radial inner guide wire clamp screw is arranged on the inner guide wire connection joint. A radial output cable guide wire clamp screw and a radial output cable clamp screw are arranged on the output cable connection joint. According to the high-voltage output safety joint, the connection joint between the guide wire and the output cable is arranged in a box body, the connection joint and the box body are connected with the ground through the fixing seat sleeve on the upper end of the connection joint, and therefore safety performance of the high-voltage output joint is effectively guaranteed.

Description of drawings
Embodiment
By reference to the accompanying drawings embodiment of the present utility model is described.
Such as accompanying drawing, the safety joint of this High voltage output has an insulating case 1, and the upper end of this insulating case 1 is provided with external screw thread, is provided with internal thread in the lower end of insulating case 1.Threaded engagement through insulating case 1 upper end connects a fixed seating 2, the output cable wire output protector 3 that is connected of the external screw thread through these fixed seating 2 tops.Lower end at insulating case 1 connects an inside conductor jointing 4 through threaded engagement.Set gradually from the bottom to top output cable jointing 5, spring 6 and insulation pressure pipe 7 in insulating case 1, the upper end of this insulation pressure pipe 7 is with outward flange, and this outward flange is interposed between the upper surface and output cable wire output protector 3 of insulating case 1.The upper surface of described inside conductor jointing 4 contacts cooperation with the lower end surface of described output cable jointing 5.The inside conductor that is provided with radially at described inside conductor jointing 4 fixes screw 8, and the output cable wire that is provided with radially at described output cable jointing 5 fixes screw 9 and the fixing of output cable radially screw 10.
When the utility model was installed, the ladder end face of fixed seating 2 matched with power transmission and distribution transformer or high voltage source fuel tank case lid, and utilizes screw to be connected and fixed, and realized the assembling of this joint and power transmission and distribution transformer or high voltage source tank body of oil tank.Power supply inside conductor in the case penetrates in the centre bore of inside conductor jointing 4 bottoms and fixes screw 8 by inside conductor and fixes.The upper surface of inside conductor jointing 4 is arranged to taper seat with the contact-making surface of output cable jointing 5 and is contacted cooperation.Output cable passes output cable wire output protector 3 successively, insulation pressure pipe 7, spring 6 enter in the output cable jointing 5, and fixingly reaches being connected and fixed of output cable wire and output cable jointing 5 by what the cable on the output cable jointing 5 fixed that screw 10 and output cable wire fix that screw 9 realizes output cables and output cable jointing 5.
Insulating case 1 of the present utility model and insulation pressure pipe 7 can adopt PTFE machine-shaping.
