Combined binding post

Abstract

The invention discloses a combined binding post, which comprises a conductive bushing, a binding post screw rod and a fixed column, wherein the side surface of the conductive bushing is provided with an opening I and an opening II, the binding post screw rod is slidably connected with the conductive bushing through the opening I, an opening III for the fixed column to penetrate and slide is formed in the surface of the conductive bushing, a fourth opening for the fixing column to penetrate through and slide is formed in the surface of the binding post screw rod, and the binding post screw rod is made of martensitic stainless steel materials; and the combined binding post further comprises two clamping structures, and the fixed column is fixed under the action of the two clamping structures through vertical movement of the fixed column. The strength of the whole structure is guaranteed by using the high-strength binding post screw rod made of stainless steel, and the effect of guaranteeing the stability of the whole structure is achieved by using the fixed column and matching the fixed column with the clamping mechanisms.

Description

technical field [0001] The invention relates to the technical field of terminal, in particular to a combined terminal. Background technique [0002] At present, in the field of aviation airborne electronic equipment, the input or output terminals of a large number of airborne electronic equipment are in the form of binding posts. Therefore, it will be paralyzed and cannot work normally, so the requirements for the strength, service life and reliability of the binding post are becoming more and more stringent. [0003] At present, most of the existing combined terminals are made of copper alloy material as a whole. If the threads at both ends are easily worn out if they are frequently disassembled and assembled, they cannot effectively cooperate with the nuts. The nuts will loosen during the vibration of the airborne electronic equipment, so that the screws installed on the The lugs on the terminals cannot be effectively attached, which affects the input or output of the air...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a combined terminal, which ensures the strength of the overall structure by using high-strength stainless steel terminal screws, and ensures the strength of the overall structure by using a fixed column and cooperating with a clamping mechanism. The stability effect solves the problem that most of the existing combined terminals are made of copper alloy material as a whole. If the threads at both ends are frequently disassembled and assembled, they are easy to wear and cannot effectively cooperate with the nuts. The nuts are loose, so that the lugs installed on the terminals cannot be effectively fitted, which affects the input or output of the airborne electronic equipment; the terminals made of copper alloy materials are used as a whole, especially the terminals below M8. When the force-limiting torque wrench is operated, it is easy to operate with excessive torque, which will cause the terminal screw of the terminal to break and affect the input or output of the airborne electronic equipment. At the same time, the fixed column cannot be effectively fixed during use, thereby causing the terminal screw to break The fixation is not strong enough, which makes the problem of poor practicability
