In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the description of the present invention, it should be understood that 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. In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.

In one embodiment, referring to fig. 1 to 3, an ultrasonic driving handle includes an ultrasonic transducer 10, a main housing 20, an adapter plate 30, a rear housing 40 and a cable assembly 50. The ultrasonic transducer 10 includes an ultrasonic horn 11. The ultrasonic horn 11 is disposed within the main housing 20. An opening is formed in the rear end of the main housing 20, and the adapter plate 30 is covered on the opening. The rear end housing 40 is connected to the main housing 20, and the rear end housing 40 is used for pressing the adapter plate 30 and blocking the opening. The cable assembly 50 is located in the rear housing 40, and the cable assembly 50 is electrically connected to the interposer 30.

The ultrasonic driving handle is electrically connected with the cable assembly 50 by the adapter plate 30, so that the structure of the ultrasonic driving handle is optimized, the assembly of the rear end shell and the main shell is simpler, and the assembly qualification rate is high; meanwhile, when the rear end housing 40 is assembled to the main housing 20, the rear end housing 40 directly presses and fixes the interposer 30, so that the sealing performance of the main housing 20 can be ensured when the current path of the cable assembly 50 extends into the main housing 20.

Further, referring to fig. 2, the ultrasonic driving handle further includes a connecting shell 60. The main housing 20 is connected to the rear end housing 40 through the connection housing 60. The opening is provided in the connection housing 60, and the interposer 30 is connected to the connection housing 60. One end of the connecting shell 60 is sleeved in the main shell 20, and the other end is sleeved in the rear shell 40. A first sealing ring 61 is disposed between the connecting shell 60 and the main shell 20. A second sealing ring 62 is arranged around the opening on the end surface of the connecting shell 60 facing the rear end shell 40. The second sealing ring 62 abuts against the surface of the adapter plate 30. Therefore, on one hand, after the main housing 20 is connected with the rear end housing 40 through the connecting housing 60, the outer side wall of the main housing 20 can be well connected with the outer side wall of the rear end housing 40, the gap is small, and the wall surface is flat; on the other hand, the division into three parts facilitates machining. In addition, by the first seal ring 61 and the second seal ring 62, good sealing performance in the main casing 20 can be ensured.

Specifically, referring to fig. 2, fig. 2 illustrates two threaded connection portions 63 on the connection housing 60, wherein the connection housing 60 is detachably connected to the main housing 20 in a threaded manner, i.e., one of the threaded connection portions 63 is formed. The connecting shell 60 and the rear shell 40 are also detachably connected in a thread fit manner to form another thread connecting part 63. Thus, the main housing 20, the connecting housing 60 and the rear end housing 40 can be assembled together quickly, and the operation is convenient; in addition, the current path of the cable assembly enters the main shell through the adapter plate, so that the main shell, the connecting shell and the rear end shell can be quickly assembled by adopting a threaded connection mode, and the problem of cable winding when the rear end shell is assembled can be avoided. Of course, the connecting shell 60 and the main housing 20 can be detachably connected by means of snap-in, and the connecting shell 60 and the rear end shell 40 can be detachably connected by means of snap-in.

Further, it is understood that in order to stably locate first sealing ring 61 between coupling housing 60 and main housing 20, a receiving groove adapted to first sealing ring 61 is provided, for example, on an outer wall of coupling housing 60 or an inner wall of main housing 20. Similarly, in order to stably locate the second sealing ring 62 between the connecting shell 60 and the rear end shell 40, a receiving groove adapted to the second sealing ring 62 is provided, for example, on an outer wall of the connecting shell 60 or an inner wall of the rear end shell 40.

Further, referring to fig. 2, a circumferential first step 41 is disposed on an inner wall of the rear end shell 40, and the first step 41 is used for enabling the adapter plate 30 to be pressed and plugged at the opening. An annular pad 70 is arranged between the first step 41 and the adapter plate 30, a circumferential second step 71 is arranged on the annular pad 70, and the second step 71 is arranged corresponding to the first step 41. Therefore, the electronic components on the interposer 30 are accommodated in the space surrounded by the annular pad 70, and the annular pad 70 protects the interposer 30, thereby avoiding the rear-end housing 40 from contacting and damaging the interposer 30 to a certain extent.

Further, referring to fig. 2, the rear shell 40 is provided with a mounting opening 42. The cable assembly 50 includes a conductive cable 51, a cable sheath 52, and a sheath clamp ring 53. The conductive cable 51 is electrically connected with the adapter plate 30, the cable sheath 52 is sleeved outside the conductive cable 51, the cable sheath 52 and the sheath press ring 53 are both arranged at the installation opening 42, and the sheath press ring 53 is used for enabling the cable sheath 52 to be tightly pressed and fixed at the installation opening 42.

Further, referring to fig. 2, a third circumferential step 43 is further disposed on the inner wall of the rear shell 40. A snap ring 54 and a fastener 55 are further arranged between the third step 43 and the sheath press ring 53. The snap ring 54 is sleeved outside the conductive cable 51, and the fastening member 55 penetrates through the wall of the rear end housing 40 and presses the conductive cable 51. Thus, the cable assembly 50 can be stably mounted on the rear end housing 40. Specifically, the number of the snap rings 54 may be one, two or more, and the more the snap rings 54, the greater the pullout resistance of the conductive cable 51. Further, the fastener 55 may be, for example, a screw, a bolt, a screw, or the like.

In one embodiment, referring to fig. 1, 3-8, the ultrasonic drive handle further comprises a front shell 80, an electrode ring, and a conductor. The conductor is, for example, a wire or a conductive pin 13. The conductor will be described in detail as an example of the conductive pin 13. The front end housing 80 is coupled to the main housing 20. The ultrasonic horn 11 is disposed in the main housing 20, and a fixing flange 111 is sleeved on an outer side wall of the ultrasonic horn 11. The outer edge of the fixed flange 111 is circumferentially provided with a first mounting groove 112, and a through hole 113 is formed in the axial direction of the fixed flange 111. A third sealing ring 12 is arranged in the first mounting groove 112, and the third sealing ring 12 is in interference fit with the inner wall of the front end shell 80. The conductive pin 13 is disposed in the through hole 113, one end of the conductive pin 13 is electrically connected to the electrode ring, and the other end of the conductive pin 13 is electrically connected to the adapter plate 30 through a wire.

Because the third sealing ring 12 is arranged on the fixed flange 111, the sealing performance between the fixed flange 111 and the front end shell 80 can be ensured, and the sealing performance of the area where the ultrasonic horn 11 is located can be ensured. In addition, because the conductive pin 13 is arranged in the through hole 113 in a penetrating manner, on one hand, the electric connection between the conductive cable 51 positioned at the two ends of the ultrasonic amplitude transformer 11 and the electrode ring can be realized, and the electric connection of electric signals at the two ends of the fixing flange 111 can be realized, on the other hand, the device is simple in structure, meanwhile, the sealing performance of the area where the ultrasonic amplitude transformer 11 is positioned can be ensured, and the assembly qualified rate is high.

In one embodiment, referring to fig. 3 and 4, the ultrasonic driving handle further includes a fourth sealing ring 14 disposed in the through hole 113. The fourth sealing ring 14 is sleeved outside the conductive pin 13. Therefore, the fourth seal ring 14 can enable the outer wall of the conductive pin 13 to be in sealing fit with the inner wall of the through hole 113, and the sealing performance is ensured. Specifically, the conductive pin 13 is specifically a solid conductive pin 13. An insulating layer is arranged outside the conductive pin 13, so that the defect of high-voltage discharge is avoided.

In one embodiment, referring to fig. 3, 4 and 8, the ultrasonic driving handle further includes a rotation stopper 15 disposed on the fixing flange 111. The rotation stopper 15 is adapted to be inserted into the rotation stopper 811 of the front end housing 80. Therefore, on one hand, under the action of the rotation stopping piece 15, the ultrasonic amplitude transformer 11 and the front end shell 80 are relatively fixed, and the mutual rotation of the ultrasonic amplitude transformer and the front end shell can be avoided; on the other hand, the rotation stopping piece 15 can be manufactured independently of the ultrasonic amplitude transformer 11, so that the mold opening machining is convenient, the production difficulty is low, and the large-scale production can be realized.

In one embodiment, referring to fig. 3, 4 and 8, the number of the rotation stopping members 15 is at least two, and the rotation stopping ports 811 are disposed in one-to-one correspondence with the rotation stopping members 15. The rotation stopping members 15 are rotation stopping sleeves, one of the rotation stopping members 15 is inserted into the through hole 113 and sleeved outside the conductive pin 13, and a portion of one of the rotation stopping members 15, which is located outside the through hole 113, is inserted into the rotation stopping opening 811. The fixing flange 111 is further provided with blind holes 114 corresponding to the other rotation stopping members 15, the rotation stopping members 15 are inserted into the blind holes 114, and the rotation stopping members 15 outside the blind holes 114 are inserted into the rotation stopping openings 811. Thus, the ultrasonic horn 11 is fixedly arranged on the front end shell 80 and the main shell 20 by adopting more than two rotation stopping pieces 15, and the structural stability is good.

Specifically, referring to fig. 3, 4 and 8, the rotation stopping member 15 may be two, one of which is inserted into the through hole 113 and the other of which is inserted into the blind hole 114. In addition, the trepan and the blind hole 114 are respectively located at two opposite sides of the fixing flange 111.

As an alternative, the rotation stopping members 15 may be three, one of which is inserted into the through hole 113, and the other of which is inserted into the two blind holes 114. Of course, the rotation stop members 15 may also be four, five or another number.

As an alternative, the rotation stopping member 15 may be only one, that is, the rotation stopping member 15 is inserted into the through hole 113, and the fixing flange 111 does not need to be provided with the blind hole 114.

As an alternative, the rotation stop member 15 is integrated with the ultrasonic horn 11.

In one embodiment, referring to fig. 3, 4 and 8, a circumferential first bump is disposed on a needle wall of the conductive needle 13, an accommodating portion corresponding to the first bump is disposed on an inner wall of the trepan of the rotation stopping member 15, and the first bump is disposed in the accommodating portion. The outer wall of the rotation stopping piece 15 is provided with a circumferential second convex block, and the second convex block is abutted to the side face of the fixing flange 111. Thus, the rotation stopping member 15 is abutted against the side surface of the fixing flange 111 through the second protrusion, so that the axial limitation on the side surface of the fixing flange 111 is realized. The conductive pin 13 is disposed in the receiving portion through the first protrusion, and is also axially retained in the trepan boring of the rotation stop member 15. In addition, the specific shape of the needle wall of the conductive needle 13 is a step shape, and the conductive needle can be directly inserted into the trepan boring of the rotation stopping piece 15 to perform limiting and fixing in the axial direction; the outer wall of the rotation stopping member 15 is stepped, and the rotation stopping member is directly inserted into the through hole 113 to perform limiting and fixing in the axial direction.

Further, referring to fig. 3, fig. 6 and fig. 7, a circumferential flange 81 is disposed on an inner wall of the front end housing 80, and a rotation stopping opening 811 adapted to the rotation stopping member 15 is disposed on the flange 81. Thus, when the rotation stop member 15 is fitted into the rotation stop opening 811 of the flange 81, the rotation stop member 15 and the front end housing 80 are fixedly engaged with each other, and the ultrasonic horn 11 is prevented from rotating relative to the front end housing 80.

The fixing flange 111 is located outside the main casing 20, and an elastic pad 94 is disposed between the fixing flange 111 and an end surface of the main casing 20. Therefore, on one hand, the main shell 20, the front end shell 80, the elastic cushion 94, the conductive pin 13, the third sealing ring 12, the fourth sealing ring 14, the rotation stopping piece 15 and the like can be assembled and matched conveniently, the assembly is quick and convenient, and the sealing performance after the assembly is finished can be ensured; on the other hand, the elastic pad 94 has a good shock absorption effect, and has a small influence on the natural frequency of the ultrasonic transducer 10, thereby being beneficial to reducing vibration and heat generation.

Further, referring to fig. 3, the ultrasonic driving handle further includes a supporting pad 95 disposed between the elastic pad 94 and the end surface of the main housing 20. The supporting pad 95 specifically adopts a plastic piece, the supporting pad 95 is provided with a through hole for the conductive pin 13 to pass through, and the conductive pin 13 is sleeved in the through hole. As such, the supporting pad 95 plays a role of supporting, insulating and isolating the conductive pin 13.

As an alternative, the front end housing 80 may also be sleeved inside the main housing 20, and the fifth sealing ring 93 may also be disposed at a connection position between the front end housing 80 and the main housing 20 to ensure the sealing property after the connection between the two.

In one embodiment, referring to FIG. 3, the ultrasonic drive handle further includes an insulating spacer sleeve 96. The electrode rings include an inner electrode ring 91 and an outer electrode ring 92. The insulating isolation sleeve 96 is arranged between the inner electrode ring 91 and the outer electrode ring 92, the inner electrode ring 91 is electrically connected with the conductive pin 13, the outer electrode ring 92 is sleeved inside the front end shell 80 and contacts with the inner side wall of the front end shell 80, the front end shell 80 and the main shell 20 are metal shells, and the front end shell 80, the main shell 20 and the ultrasonic horn 11 are electrically connected together. Thus, the insulating isolation sleeve 96 can realize the mutual insulating isolation between the inner electrode ring 91 and the outer electrode ring 92, and avoid the electrical contact between the inner electrode ring 91 and the outer electrode ring 92.

In one embodiment, referring to fig. 3, the insulating spacer 96 includes a first sleeve segment 961 and a second sleeve segment 962 arranged in series along the axial direction of the front end housing 80.

The front end shell 80 is in press fit with the outer electrode ring 92, or the front end shell 80 is in threaded fit with the outer electrode ring 92. Therefore, on one hand, after the protrusions 911 are arranged in the second mounting grooves 963, the inner electrode ring 91 can be axially limited and fixed in the insulating isolation sleeve 96, and the inner electrode ring 91 is prevented from moving in the axial direction relative to the insulating isolation sleeve 96; on the other hand, the insulating spacer 96 and the inner electrode ring 91 can be easily assembled into the front end housing 80, and after the insulating spacer 96 is divided into the first housing segment 961 and the second housing segment 962, the machining can be easily performed, and the production efficiency is high.

Further, specifically, the front end shell 80 is press-fitted to the outer electrode ring 92, or the front end shell 80 is screw-fitted to the outer electrode ring 92. Thus, the front end case 80 and the outer electrode ring 92 can be assembled and fixed together.
