Just as the background art, in order to solve the problem that the cable of connecting easily knoes among the prior art on the transducer subassembly, this application embodiment provides a transducer coupling assembling and supersound sword, can avoid the cable to rotate, prevents that the cable from knoing, has improved simple operation degree and user experience.

In a first aspect, embodiments of the present application provide a transducer connection assembly, and as shown in fig. 1 and 2, a transducer connection assembly 1 includes: a first connection structure 11, a male electrode 12, a second connection structure 13 and a female electrode 14. Wherein the first connecting structure 11 is rotatably connected with the second connecting structure 13. The male electrode 12 is fixedly connected to the first connecting structure 11. The female electrode 14 is fixedly connected to the second connecting structure 13, and when the first connecting structure 11 is connected to the second connecting structure 13, the male electrode 12 is rotatably connected to the female electrode 14. The first connecting structure 11 and the second connecting structure 13 can rotate relatively, and the male electrode 12 and the female electrode 14 can rotate relatively and keep electrical connection.

In a specific embodiment, when the transducer connection assembly 1 is assembled, the first connection structure 11 and the male electrode 12 may be disposed on the transducer, and the second connection structure 13 and the female electrode 14 may be connected with a cable. And of course in other embodiments the reverse may be true.

In the transducer connecting assembly 1 described above, the first connecting structure 11 and the second connecting structure 13 are rotationally connected, and the male electrode 12 and the female electrode 14 are rotationally connected. Thus, when the transducer is rotated by the cutter head assembly, the first connecting structure 11 and the male electrode 12 can rotate, but the second connecting structure 13 and the female electrode 14 cannot be rotated. Because the second connecting structure 13 and the female electrode 14 do not rotate, the cable does not rotate, so that the cable is prevented from knotting, and the operation convenience and the user experience are improved.

In one embodiment, the first connection structure 11, the male electrode 12, the second connection structure 13, and the female electrode 14 are all coaxially disposed. The first connection structure 11 rotates about its own axis with respect to the second connection structure 13, while the male electrode 12 rotates about its own axis with respect to the female electrode 14.

It can also be understood that: the axial lead of the first connecting structure 11, the axial lead of the second connecting structure 13, the axial lead of the male electrode 12 and the axial lead of the female electrode 14 are all overlapped. The first connecting structure 11 rotates around the axis relative to the second connecting structure 13, and the male electrode 12 also rotates around the axis relative to the female electrode 14.

In one embodiment, referring to fig. 3-8, the male electrode 12 includes a first male electrode 12a, a second male electrode 12b, and a third male electrode 12c electrically isolated from each other, and the female electrode 14 includes a first female electrode 14a, a second female electrode 14b, and a third female electrode 14c electrically isolated from each other. The first male electrode 12a is rotatably connected to the first female electrode 14a, the second male electrode 12b is rotatably connected to the second female electrode 14b, and the third male electrode 12c is rotatably connected to the third female electrode 14c.

Specifically, the first male electrode 12a, the second male electrode 12b, the third male electrode 12c, the first female electrode 14a, the second female electrode 14b, and the third female electrode 14c are all coaxially disposed. Thus, when the first connecting structure 11 rotates, the first connecting structure 11 drives the first common electrode 12a, the second common electrode 12b and the third common electrode 12c to rotate around the same axis.

The first male electrode 12a and the first female electrode 14a may be positive electrodes, the second male electrode 12b and the second female electrode 14b may be negative electrodes, and the third male electrode 12c and the third female electrode 14c may be signal electrodes (for transmitting control signals).

In one embodiment, referring to fig. 3-8, the male electrode 12 includes a male electrode annular wall 121, the female electrode 14 includes a female electrode annular wall 141, and the male electrode annular wall 121 is disposed outside the female electrode annular wall 141. Thus, on one hand, the structure of the male electrode 12 and the female electrode 14 is simple, and the manufacture is convenient; on the other hand, the male electrode 12 and the female electrode 14 can be ensured to be stably and electrically connected when rotating relative to each other.

In one embodiment, the male electrode 12 includes a male electrode connecting portion 122 connected to the male electrode annular wall 121, and the male electrode connecting portion 122 is fixedly connected to the first connecting structure 11. In this way, on the one hand, the male electrode 12 can be fitted on the first connection structure 11 via the male electrode connection 122; and on the other hand, can be electrically connected to other components (e.g., internal circuitry of the transducer) via the male electrode connection 122.

The bus electrode 14 includes a bus electrode connecting portion 142 connected to the bus electrode annular wall 141, and the bus electrode connecting portion 142 is fixedly connected to the second connecting structure 13. In this way, the female electrode 14 can be fitted on the second connection structure 13 through the female electrode connection portion 142 on the one hand; and on the other hand, the cable can be electrically connected to the female electrode connecting part 142.

In one embodiment, the common electrode annular wall 121 is provided with a notch 123 extending through the common electrode annular wall 121 along its axial direction. Thus, when the male electrode 12 and the female electrode 14 are sleeved, since the male electrode annular wall 121 has the notch 123, the male electrode annular wall 121 can deform to enlarge the cavity surrounded by the male electrode annular wall 121, so that the female electrode annular wall 141 can be conveniently sleeved in the cavity.

In one embodiment, the inner diameter of the male electrode annular wall 121 when not inserted into the female electrode 14 is less than the outer diameter of the female electrode annular wall 141. Thus, after the male electrode annular wall 121 and the female electrode annular wall 141 are sleeved, the male electrode annular wall 121 can clamp the female electrode annular wall 141, and the electrical contact between the male electrode annular wall and the female electrode annular wall is ensured to be good. It is understood that the male electrode annular wall 121 cannot "clamp" the female electrode annular wall 141, so that the male electrode annular wall 121 cannot rotate relative to the female electrode annular wall 141, and therefore, the inner diameter of the male electrode annular wall 121 should be slightly smaller than the outer diameter of the female electrode annular wall 141, and the difference between the two values is not limited in the embodiment of the present application.

In one embodiment, the end of the male electrode annular wall 121 adjacent the female electrode 14 is provided with a male electrode guide 124. Illustratively, the inner diameter of the male electrode guide 124 gradually decreases from the end near the female electrode 14 toward the direction away from the female electrode 14. As an example, one end of the female electrode annular wall 141 near the male electrode 12 is provided with a female electrode guide 143. Illustratively, the outer diameter of the female electrode guide 143 gradually increases from the end near the male electrode 12 toward the direction away from the male electrode 12.

By providing the male electrode guide 124 and the female electrode guide 143, the male electrode 12 and the female electrode 14 can be assembled more easily.

In one embodiment, referring to fig. 2 and 9, the first connecting structure 11 includes a first housing 111 and a first connecting member 112. Here, the first housing 111 has an accommodating cavity 1111, and the accommodating cavity 1111 penetrates the first housing 111 in the axial direction of the first connection structure 11, which can also be understood as: the first housing 111 is a hollow structure. The first connector 112 is connected to the inner wall of the receiving cavity 1111, and the male electrode 12 is embedded in the first connector 112. The first housing 111 is disposed outside the second connecting structure 13 and is rotatably connected to the second connecting structure 13, such that the first housing 111 is used for connecting to the second connecting structure 13 and the first connecting member 112 is used for assembling the male electrode 12.

In one embodiment, as shown in fig. 9 and 15, the inner wall of the receiving cavity 1111 is provided with an annular groove 1112, and the second connecting structure 13 is provided with an annular protrusion 1313 which is in clearance fit with the annular groove 1112. Thus, the annular groove 1112 and the annular protrusion 1313 are matched with each other, so that the two can be limited in the axial direction, and the first connecting structure 11 and the second connecting structure 13 are prevented from being pulled and loosened by external force applied to the first connecting structure 11 or the second connecting structure 13.

In one embodiment, referring to fig. 10 to 13, the first connecting member 112 includes a first fixing portion 1121 and a first mounting portion 1122, the first mounting portion 1122 is disposed on a side of the first fixing portion 1121 close to the female electrode 14, and a mounting cavity 1123 is disposed on the first mounting portion 1122. The first fixing portion 1121 is provided with a male electrode through hole 1124 communicating with the mounting cavity 1123, the male electrode connecting portion 122 is disposed through the male electrode through hole 1124, and the male electrode annular wall 121 is located in the mounting cavity 1123. Thus, after the male electrode 12 and the female electrode 14 are assembled, the male electrode annular wall 121 and the female electrode annular wall 141 are located in the assembly cavity 1123, and the electrical connection environment of the two is relatively closed, so that interference caused by external factors on the electrical connection of the two can be avoided.

In one embodiment, a limiting rib is disposed in the assembling cavity 1123, the limiting rib extends along the axial direction of the first connecting structure 11, and one end of the annular wall 121 of the male electrode, which is far away from the second connecting structure 13, abuts against the limiting rib. Therefore, the male electrode 12 can be limited in the axial direction by the limiting rib, and the male electrode 12 is prevented from loosening or sliding in the axial direction.

In one embodiment, as shown with reference to fig. 11 and 12, the position-limiting ribs include a first position-limiting rib 11251 and a second position-limiting rib 11252. The first limiting rib 11251 and the second limiting rib 11252 are arranged at the bottom of the assembling cavity 1123 at intervals and extend along the axial direction of the first connecting structure 11. The "bottom" of the fitting cavity 1123 refers to a cavity wall of the fitting cavity 1123 in the axial direction.

The extension length of the first limiting rib 11251 in the axial direction is longer than the extension length of the second limiting rib 11252 in the axial direction. One end of the male electrode annular wall 121 of the first male electrode 12a, which is far away from the second connection structure 13, abuts against the first limiting rib 11251; one end of the male electrode annular wall 121 of the second male electrode 12b, which is far away from the second connection structure 13, abuts against the second limiting rib 11252; an end of the male electrode annular wall 121 of the third male electrode 12c remote from the second connection structure 13 abuts against the cavity bottom of the fitting cavity 1123.

Thus, by providing the first limiting rib 11251 and the second limiting rib 11252, the first male electrode 12a, the second male electrode 12b and the third male electrode 12c can be arranged in a step shape, so as to be conveniently assembled with the first female electrode 14a, the second female electrode 14b and the third female electrode 14c.

In one embodiment, referring to fig. 3, 4 and 11, the extension 125 is disposed on the male electrode annular wall 121 on both sides of the gap 123, the extension 125 extends in a direction away from the center of the male electrode annular wall 121, and the extension 125 abuts against the wall of the assembly cavity 1123.

Thus, after the male electrode 12 is assembled with the first connector 112, the extending portion 125 on the male electrode annular wall 121 abuts against the wall of the assembly cavity 1123, so that the male electrode annular wall 121 has a supporting point in the assembly cavity 1123, the male electrode annular wall 121 can be more stable in the assembly cavity 1123, the male electrode annular wall 121 is prevented from shaking in the assembly cavity 1123, and the assembly stability of the male electrode 12 is improved.

In one embodiment, referring to fig. 13, a side of the first fixing portion 1121 remote from the first fitting portion 1122 is formed with a mounting recess 1126 for mating with an external tool. As an example, the first fitting portion 1122 is connected to the first housing 111 by a screw 1127. Thus, when assembling the first connector 112 and the first housing 111, the first connector 112 can be screwed into the first housing 111 by using an external tool to extend into the mounting recess 1126.

In one embodiment, referring to fig. 2, the second connecting structure 13 includes a second connecting member 131 and a second housing 132, the second housing 132 is disposed outside the second connecting member 131, and the second connecting member 131 is connected to the accommodating cavity 1111 of the first housing 111.

In one embodiment, as shown with reference to fig. 14 to 17, the second connector 131 includes a second assembling portion 1311 and a stepped boss portion 1312, and the stepped boss portion 1312 is disposed at a side of the second assembling portion 1311 adjacent to the male electrode 12. On the one hand, the outer periphery of the second fitting portion 1311 is formed with an annular protrusion 1313, and the annular protrusion 1313 can be engaged with the annular groove 1112 on the first connection structure 11 to firmly connect the second connection structure 13 and the first connection structure 11 in the axial direction; on the other hand, the second fitting portion 1311 has a female electrode through-hole 1314 formed therein, and the female electrode through-hole 1314 extends in the axial direction of the second coupling structure 13. The bus electrode connecting portion 142 is disposed through the bus electrode through hole 1314, and the bus electrode annular wall 141 is disposed around the stepped boss portion 1312. Thus, the female electrode 14 can be stably assembled with the second connection member 131.

In one embodiment, the stepped boss portion 1312 includes three bosses, which are sequentially connected in the axial direction of the second connecting structure 13. Among two adjacent circular truncated cones, the outer diameter of the circular truncated cone far away from the second assembling portion 1311 is smaller than the outer diameter of the circular truncated cone near the second assembling portion 1311, and the first female electrode 14a, the second female electrode 14b and the third female electrode 14c are correspondingly sleeved on the periphery of each circular truncated cone.

Specifically, the boss includes a first boss 1312a, a second boss 1312b, and a third boss 1312c. The first truncated cone 1312a is disposed on the side of the second mounting portion 1311 close to the male electrode 12, the second truncated cone 1312b is disposed on the side of the first truncated cone 1312a close to the male electrode 12, and the third truncated cone 1312c is disposed on the side of the second truncated cone 1312b close to the male electrode 12.

The present application provides in a second aspect an ultrasonic blade comprising a transducer, a blade assembly, a cable and the transducer connection assembly 1 of any of the above embodiments. The cutter head component is connected with the transducer, the first connecting structure 11 and the male electrode 12 are arranged at one end of the transducer, which is far away from the cutter head component, and the cable is connected with the second connecting structure 13 and the female electrode 14.

The ultrasonic blade is connected by rotating the first connecting structure 11 and the second connecting structure 13, and the male electrode 12 and the female electrode 14. Thus, when the transducer is rotated by the cutter head assembly, the first connecting structure 11 and the male electrode 12 can rotate, but the second connecting structure 13 and the female electrode 14 are not rotated. Because the second connecting structure 13 and the female electrode 14 do not rotate, the cable does not rotate, so that the cable is prevented from knotting, and the operation convenience and the user experience are improved.
