Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cables, and in particular to a sterilizable motor connecting cable. Background Art
[0002] When a dental implant is handheld during surgery, the motor cable must be bent back and forth at various angles, which can easily lead to bending fatigue and damage. Furthermore, the wiring harness is often at a higher risk of damage than the dental implant itself, often resulting in damaged wiring harnesses while the dental handpiece remains intact. However, because existing dental implants and motor cables are often integrated, any damage requires repair or replacement, resulting in high costs.
[0003] Furthermore, since dental implants require high-temperature steam sterilization before use in surgery to meet instrument sterilization requirements, the motor connection cable connected to the dental implant must also meet the requirements of high-temperature and high-pressure sterilization resistance. Utility Model Content

[0007] In one embodiment, the circuit board assembly further includes a jack, and a plurality of the jacks are welded on the end surface of the PCB board facing away from the multi-core cable.
[0008] In one embodiment, the clamp assembly includes a clamp and a clamp fixing ring, one end of the clamp fixing ring is provided with an internal thread, and the length of the internal thread is greater than the length of the external thread; one end of the clamp is tightly pressed against the other end of the fixing seat, and the other end is tightly pressed against the other end of the clamp fixing ring.
[0009] In one embodiment, the inner surface of the other end of the clamp fixing ring reduces its inner diameter in the direction away from the fixing seat to form a conical surface; the other end of the clamp is provided with a notch along the axial direction, and when the fixing seat is connected to the clamp fixing ring, the other end of the clamp contracts radially under the pressure of the conical surface.
[0010] In one embodiment, a groove is provided on the inner surface of the other end of the clamp.
[0011] In one embodiment, a protrusion is provided on the outer side of the other end of the clamp fixing ring.

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a sterilizable motor connection cable, including a multi-core cable 10, a first sheath 20, an aviation plug 30, a second sheath 40, a back cover 50, a circuit board assembly 60, and a clamp assembly 70. One end of the multi-core cable 10 is fixedly connected to the solder cup of the aviation plug 30, and the connection is potted with silicone 91 to ensure the sealing of the electrical path formed by the multi-core cable 10 and the aviation plug 30. The first sheath 20 is mounted outside the connection between the multi-core cable 10 and the aviation plug 30 to further ensure the moisture-proof, corrosion-resistant, high-temperature-resistant, and bending-resistant capabilities of the connection between the multi-core cable 10 and the aviation plug 30. The other end of the multi-core cable 10 is connected to the circuit board assembly 60, and the connection is integrally encapsulated with epoxy glue 92 to ensure the sealing of the electrical path formed by the multi-core cable 10 and the circuit board assembly 60; further, the back cover 50 is sleeved over the connection between the multi-core cable 10 and the circuit board assembly 60 through the second sheath 40 to further ensure the moisture-proof, corrosion-resistant, high-temperature-resistant, and bending-resistant capabilities of the connection between the multi-core cable 10 and the aviation plug 30. One end of the clamp assembly 70 abuts against one end of the circuit board assembly 60, and the other end is clamped on the multi-core cable 10 to prevent the multi-core cable 10 from being pulled axially, so as to avoid the connection between the multi-core cable 10 and the circuit board assembly 60 from breaking, or the core of the multi-core cable 10 from breaking.
[0031] The sterilizable motor connecting cable provided by the utility model is easy to disassemble and connect to the motor. Compared with the integrated dental implant and motor connecting cable structure, the replacement and maintenance costs are low and the risk of bending and damage is low.
[0032] Specifically, the first sheath 20 has a conical structure, with the outer diameter of its first end being smaller than that of its second end. The inner diameter of the first end of the first sheath 20 is equal to the outer diameter of the multi-core cable 10. The inner surface of the second end of the first sheath 20 is provided with a first engaging groove for connecting to the aviation plug 30. The aviation plug 30 is a prior art product, and its detailed structure is not further described here.
[0033] The second sheath 40 has a conical structure, the outer diameter of its first end is smaller than the outer diameter of its second end, and the inner diameter of the first end of the second sheath 40 is equal to the outer diameter of the multi-core cable 10; the inner surface of the second end of the second sheath 40 is provided with a second clamping groove for connecting the clamp assembly 70.
[0034] Please combine Figure 3 , the circuit board assembly 60 includes a PCB board 61, a fixing seat 62, a screw 63 and a jack 64. The other end of the multi-core cable 10 is electrically connected to the PCB board 61 by welding. The PCB board 61 is fixed to one end of the fixing seat 62 by a screw 63, and the other end of the fixing seat 62 is provided with an external thread 621. Specifically, the screw 63 can be a pan head cross screw. A plurality of the jacks 64 are welded and fixed on the end face of the PCB board 61 facing away from the multi-core cable 10, and are used to connect external equipment (such as a dental implant machine) and conduct the circuit. The jack 64, PCB board 61, screw 63 and fixing seat 62 are integrally potted with epoxy glue to ensure the sealing of the environment in which the conductive components are located.
[0035] Please combine again Figure 4 and Figure 5The clamp assembly 70 includes a clamp 71 and a clamp fixing ring 72. One end of the clamp fixing ring 72 is provided with an internal thread 721, the length of the internal thread 721 being greater than the length of the external thread 621, and the fixing seat 62 is connected to the clamp fixing ring 72 via the external thread 621 and the internal thread 721. When the locking cam 72 is in the closed position, the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, so that the locking cam 72 is locked.
[0036] Furthermore, if Figure 4 As shown, a groove 712 is provided on the inner surface of one end of the clamp 71 away from the fixing seat 62. The cross-section of the groove 712 can be V-shaped. The design of the groove 712 can increase the friction between the clamp 71 and the multi-core cable 10, further preventing the multi-core cable 10 from being pulled axially.
[0037] Furthermore, an elastic member 80 is provided between the multi-core cable 10 and the second sheath 40. The elastic member 80 is sleeved outside the multi-core cable 10 and located inside the second sheath 40. The elastic member 80 may be a pagoda spring. The end surface of the large-diameter end of the elastic member 80 is in contact with the other end surface of the clamp fixing ring 72 to prevent the elastic member 80 from axially moving on the multi-core cable 410.
[0038] The rear cover 50 is sleeved over the second sheath 40, the clamp fixing ring 72 and the fixing seat 62 to prevent the second sheath 40 from falling off the clamp fixing ring 72. The rear cover 50 is connected to an external device (eg, a dental implant).
[0039] Therefore, the present invention effectively overcomes the shortcomings of the prior art and possesses high industrial value. The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
