It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

In addition, it should be noted that the terms "front end" and "rear end" refer to that the end of the tool close to the workpiece to be machined is the "front end" and the end far from the workpiece to be machined is the "rear end" during use. As shown in fig. 1 to 3, the upper end is exemplified as the rear end and the lower end is exemplified as the front end. "axial" refers to the gaze direction of the ultrasonic principal axis.

Referring to fig. 1 to 4, a conductive female head (hereinafter, also referred to as a conductive female head) 10 of an ultrasonic spindle according to an embodiment includes a first conductive body 100, a second conductive body 200, and a soldering body 300, wherein the first conductive body 100 and the second conductive body 200 are insulated from each other, the soldering body 300 is electrically connected to the first conductive body 100, a rear end of the soldering body 300 extends rearward from the first conductive body 100 along an axial direction, and a rear end of the soldering body 300 extends rearward from the second conductive body 200 along the axial direction.

When assembling, the conductive female head 10 is assembled inside the front end of the push rod, and the assembling diameter inside the front end of the push rod is limited. The traditional female head of leading electrically conductive directly will first electric wire welding at the rear end face of first electric conductor, if the welding position is too little, then be insecure between first electric wire and the first electric conductor, if the welding position is too big, then unable equipment is in limited assembly diameter after first electric wire and the welding of first electric conductor. Therefore, in this embodiment, when the first conductor 100 needs to be electrically connected to an external power source through the first wire, the first wire can be welded to the inner side of the portion of the welding body 300 extending out of the first conductor 100 and the second conductor 200, so as to electrically connect the first wire to the first conductor 100, and the welding area of the welding body 300 is increased when the first wire is welded under the condition of a certain assembly diameter, thereby effectively ensuring the welding point to be firm, and avoiding the electric performance of the ultrasonic spindle from being affected by the falling off of the wire and the first conductor 100.

Specifically, the first conductor 100 and the second conductor 200 may be made of metal, such as brass. Solder body 300 is made of a conductive material, and may be made of a metal material such as brass or beryllium copper.

Further, the second conductor 200 is provided inside the first conductor 100, and the first conductor 100 and the second conductor 200 are connected integrally through the insulator 400. Therefore, the structural design is more reasonable. For example, the first conductor 100 is a cathode tube, the second conductor 200 is a cathode pin, the cathode pin is inserted into the cathode tube, and the cathode pin and the cathode tube are spaced apart from each other by the insulator 400.

Further, the rear end of the first conductor 100 is provided with a fixing portion 110, the fixing portion 110 is used for connecting a welding body 300, and the welding body 300 is used for connecting a first wire. For example, the fixing portion 110 is a circular tubular structure. The first conductor 100 is further provided with an external thread 130, so that the first conductor 100 can be screwed to the front end of the push rod through the external thread 130. Of course, in other embodiments, the first conductor 100 may omit the external thread, and the first conductor directly performs the interference fit with the push rod.

The rear end of the second conductor 200 is provided with a wire connection portion 210, the rear end of the wire connection portion 210 extends rearward in the axial direction from the first conductor 100, and the wire connection portion 210 is used for connecting a second wire. Similarly, the second wire is also soldered to the wiring portion 210 of the second conductor 200.

Further, the wire connecting portion 210 is spaced apart from the fixing portion 110 and the soldering body 300 by the insulator 400, so that the wire connecting portion 210 can be effectively prevented from being electrically connected to the first conductor 100 by the fixing portion 110 and the soldering body 300. For example, an insulator 400 is disposed between the fixing portion 110 and the wire connecting portion 210 and at the rear end surface of the fixing portion 110 to better isolate the wire connecting portion 210 from the fixing portion 110.

Further, the rear end surface of the wire connecting portion 210 is also provided with an insulator 400. Therefore, the rear end surface of the wire connection portion 210, and the space between the wire connection portion 210 and the solder body 300 are covered with the insulator 400, and the remaining portion of the wire connection portion 210 is exposed outside the insulator 400.

Further, the wire connecting portion has a side surface exposed to the insulator. That is, a part of the peripheral side of the wire connecting portion 210 is exposed outside the insulator 400, and the second electric wire is welded to the side surface of the wire connecting portion 210 exposed outside the insulator 400 by welding, so that the firmness between the second electric wire and the second conductor 200 can be improved. Meanwhile, since a part of the side surface of the wire connecting portion 210 is exposed outside the insulator 400, the insulator 400 is not disposed at the part, and a space is provided for a solder joint of the second wire, so that the conductive female terminal 10 is prevented from being not mounted in the push rod after the second wire is soldered to the wire connecting portion 210. Compared with the conventional method of soldering the second wire to the rear end surface of the second conductor by using the female conductive connector, in the present embodiment, the second wire is soldered to the side portion of the wire connecting portion 210, and the wire connecting portion 210 extends out of the fixing portion 110 of the first conductor 100, so that the solder joint contact area between the second wire and the wire connecting portion 210 can be increased, and the diameter of the second conductor 200 cannot be increased to prevent the second wire from being assembled into the push rod. Specifically, the side surface of the wire connection portion exposed out of the insulator is recessed radially inward to form a recess. Therefore, a larger space for avoiding the solder joint can be provided, and the conductive female terminal 10 can be prevented from being mounted in the push rod after the second wire is soldered to the wiring portion 210.

Further, the soldering body 300 includes a soldering pipe portion 310 and a soldering terminal portion 320, the soldering pipe portion 310 is sleeved outside the first conductive body 100, and the soldering terminal portion 320 extends rearward from the first conductive body 100 along the axial direction. Specifically, the welded tube portion 310 is sleeved outside the fixing portion 110 at the rear end of the first conductor 100, the welded tube portion 310 is of a tubular structure, and the fixing portion 110 is also of a tubular structure, so that the contact area between the welded tube portion 310 and the fixing portion 110 is larger, and the firmness between the welded tube portion 310 and the fixing portion 110 is improved. The soldering tab portion 320 may be an elongated arc-shaped structure, and the soldering tab portion 320 is formed by removing another part of the arc-shaped structure from a hollow tube, so as to provide a larger contact surface for the soldering point of the first wire and improve the firmness between the first wire and the first conductor 100. And also provides enough space for wiring because the overall size of the solder point of the first wire connected to the first conductor 100 and the solder point of the second wire connected to the second conductor 200 is smaller than the outer diameter of the first conductor 100, otherwise the wires cannot pass through the inside of the push rod.

Further, the soldering lug portion 320 and the soldering tube portion 310 are integrally formed, so that the process is simple, and the structure is firmer. The soldering body 300 and the first conductor 100 are separated, and the soldering body 300 is sleeved outside the first conductor 100. Of course, in other embodiments, the welding body 300 may be integrated with the first conductive body 100.

Further, a first connecting portion 120 is disposed at a front end of the first conductor 100, a second connecting portion 230 is disposed at a front end of the second conductor 200, and the first connecting portion 120 is annular and surrounds the second connecting portion 230. The second connecting portion 230 is provided with a socket 240, so that when the female conductive connector 10 is electrically connected to the conductive connector, the conductive connector can be inserted into the socket 240, the stability between the female conductive connector 10 and the conductive connector is improved, and the conductive performance between the female conductive connector 10 and the conductive connector is ensured.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
