Knife handle electric conductor

Abstract

The invention provides a knife handle electric conductor. The knife handle electric conductor is composed of a contact negative electrode, two insulating sleeves, a contact positive electrode and a nut. The contact negative electrode is made of a copper alloy plated with a hard gold alloy coating film, the upstream of the contact negative electrode is provided with a through hole with an inner step, and a threaded extending end is formed on the outer surface of the downstream of the contact negative electrode; each insulating sleeve is provided with a through hole, the insulating sleeve with an outer step is arranged in the through hole of the inner step at the upstream, and the insulating sleeve with the air hole is arranged at the downstream of the through hole in a close fit manner; thecontact positive electrode is made of copper alloy plated with a hard gold alloy plated film, is arranged in the two through holes of the two insulating sleeves at the upstream and the downstream ina tight fit manner, and is respectively provided with a cone with a large diameter and an inclination angle and a positive terminal with a small diameter; and the screw cap is locked and fixed at thethread extending end.

Description

[0002] The new type of ultrasonic handle assembly is such as the patent case of China Announcement No. CN104526751. Its main structural features are: including a handle shell, piezoelectric ceramics, and a knife sleeve connected to the handle shell; the piezoelectric ceramics are used to convert electrical energy into It is mechanical vibration energy and generates vibration; the tool sleeve includes a horn part, a cutter head connected with the horn part and used for processing workpieces, and the horn part is connected with piezoelectric ceramics and used to connect piezoelectric ceramics After the vibration is amplified, it is transmitted to the cutter head; the piezoelectric ceramic is located in the cavity of the tool handle shell; the positive and negative electrodes of the piezoelectric ceramic are connected with wires, and the wires are electrically connected with conductive parts; The handle housing is provided with two mounting grooves, each mounting groove runs through the outer wall of the handle housing; an insulating sleeve is installed in the mounting groove, and the two conductive parts are inserted into each insulating sleeve correspondingly. And the conductive part is separated from the tool handle shell through the insulating sleeve; the conductive part has an outer end surface exposed outside the tool handle shell; and the main disadvantage of its composition is: the design position of the wire and the insulating sleeve is installed on the spindle. , will lead to poor wire contact and poor handle balance due to a micropollutant

[0003] Existing central processing machine ultrasonic cutting knife handle system such as China Taiwan Announcement No. TWM454887 patent case, its main structural features are: include a knife handle, a plurality of piezoelectric sheets and a joint rod, wherein the joint rod is fixed on the knife handle, and The two ends of these piezoelectric sheets are divided into positive and negative polar ends, and these piezoelectric sheets are stacked together and fixed on the joint rod, and let the polar ends with the same polarity be adjacent, and these piezoelectric sheets The piezoelectric sheet generates ultrasonic-level vibration and drives the joint rod to vibrate linearly relative to the knife handle; accordingly, the joint rod clamps a cutting knife, and through the ultrasonic-level vibration of these piezoelectric sheets, the cutting can be driven. The knife produces ultrasonic-level linear vibration, so the cutting knife can be used to cut workpieces; the main disadvantage of its composition is: the joint rod is assembled on the knife handle, and the assembly balance accuracy and quality cannot be controlled
