Description

Technical Field

[0001] The present invention relates to the technical field of wire harness components, and particularly relates to a waterproof radio frequency wire connector for medical equipment and a radio frequency wire harness assembly. Background Art

[0002] In the field of medical equipment, the stability and security of signal transmission are crucial, which are directly related to the accuracy of diagnostic results and the smooth progress of the treatment process. As a key component for connecting signal transmission, the performance of the radio frequency wire connector plays a decisive role in the operation of the entire medical equipment.

[0003] With the rapid development of medical technology, higher requirements are put forward for the accuracy and reliability of medical equipment, which also makes the radio frequency wire connector must have high stability and excellent waterproof performance. To meet the waterproof requirement, traditional radio frequency wire connectors mostly adopt the relatively common waterproof design of rubber sealing rings. During the daily use of the equipment, especially in some medical scenarios where the radio frequency wire needs to be frequently plugged and unplugged, such as mobile medical monitoring equipment, multi-functional surgical instruments, etc., problems gradually emerge.

[0004] Due to the physical properties of rubber itself, under the friction generated by frequent plugging and unplugging, the rubber sealing ring is extremely easy to wear, resulting in the destruction of its originally tight sealing structure. At the same time, when the rubber is exposed to the air for a long time, it will age due to oxidation and other reasons, further weakening its sealing performance. Once the sealing performance of the rubber sealing ring decreases, moisture may seep into the interior of the radio frequency wire connector, which will not only interfere with signal transmission, causing problems such as signal attenuation and distortion, seriously affecting the detection accuracy and diagnostic accuracy of medical equipment, but also may cause safety hazards such as short circuits, posing threats to the life safety of patients and the operation safety of medical staff.

[0035] The present invention will be further described in conjunction with the following embodiments.

[0037] A RF cable harness assembly described in this embodiment includes a connector 7 and a waterproof medical device RF cable connector; the connector 7 is provided with a plug-in table 71 that cooperates with the insertion interface 14; a fixing pin 72 that cooperates with the tooth groove 41 is telescopically movable on the outer wall of the plug-in table 71; a plug-in spring is provided between the fixing pin 72 and the plug-in table 71.

[0038] Specifically, for the waterproof medical device RF cable connector described in this embodiment, before the connector 7 and the connector are installed, the upper guiding block 51 is located at the other end of the second upper arc groove 44, and the lower guiding block 52 is located at the other end of the second lower arc groove 32. At this time, the entire arc-shaped sealing strip 5 is retracted into the receiving cavity 15.

[0039] When installing the connector 7 to the connector head, insert the plugging platform 71 into the plugging interface 14, so that the fixing pin 72 is clamped with the tooth groove 41. Then, rotate the connector 7. During the rotation of the connector 7, drive the arc sealing strip 5 to move through the driving component until the upper guiding block 51 moves to the other end of the first upper arc groove 43 and the lower guiding block 52 moves to the other end of the first lower arc groove 31. At this time, the arc sealing strip 5 extends from the accommodating cavity 15 into the plugging interface 14 and abuts against the outer wall of the plugging platform 71, effectively playing a role in waterproofing.

[0040] Before installation in this embodiment, the arc sealing strip 5 is accommodated in the accommodating cavity 15, reducing the friction between the arc sealing strip 5 and the surface of the plugging platform 71 during the connection process, thereby avoiding the loss and aging of the sealing ring; when the installation is complete, by rotating the connector 7, the arc sealing strip 5 automatically moves to achieve effective sealing.

[0041] For a waterproof medical device RF cable connector described in this embodiment, a curve spring 45 is provided between the annular driving ring 4 and the upper annular boss 2; a driving component is provided between the annular driving ring 4 and the upper annular boss 2. For a waterproof medical device RF cable connector described in this embodiment, the driving component includes a driving pin 63 movably arranged at the top of the annular driving ring 4 and a driving groove arranged at the bottom of the upper annular boss 2; the driving pin 63 is movably arranged in the driving groove. Through the cooperation of the curve spring 45 and the driving component in this embodiment, the telescopic movement of the arc sealing strip 5 in the accommodating cavity 15 can be controlled.

[0042] A waterproof medical device RF cable connector according to this embodiment, a limiting groove 61 is provided along the diameter direction at the top of the annular driving ring 4; a limiting seat 62 is slidably arranged in the limiting groove 61; a driving pin 63 is telescopically arranged at the top of the limiting seat 62; a driving spring is arranged between the driving pin 63 and the limiting seat 62. A waterproof medical device RF cable connector according to this embodiment, the driving groove includes a first arc groove 21, a second arc groove 22, a first straight groove 23 and a second straight groove 24; one end of the first arc groove 21 is connected to one end of the second arc groove 22; the other end of the first arc groove 21 is connected to one end of the first straight groove 23; the other end of the second arc groove 22 is connected to one end of the second straight groove 24; the other end of the first straight groove 23 is connected to the other end of the second straight groove 24; the distance between one end of the first arc groove 21 and the center of the upper annular boss 2 is less than the distance between the other end of the first arc groove 21 and the center of the upper annular boss 2; the distance between one end of the second arc groove 22 and the center of the upper annular boss 2 is greater than the distance between the other end of the second arc groove 22 and the center of the upper annular boss 2; the distance between the other end of the first straight groove 23 and one end of the first arc groove 21 is less than the distance between one end of the first straight groove 23 and one end of the first arc groove 21. A waterproof medical device RF cable connector according to this embodiment, the depth of one end of the first arc groove 21 is greater than the depth of the other end of the first arc groove 21; the depth of the other end of the first arc groove 21 is less than the depth of one end of the first straight groove 23; the depth of one end of the first straight groove 23 is greater than the depth of the other end of the first straight groove 23; the depth of the other end of the first straight groove 23 is less than the depth of the other end of the second straight groove 24; the depth of the other end of the second straight groove 24 is greater than the depth of one end of the second straight groove 24; the depth of one end of the second straight groove 24 is less than the depth of the other end of the second arc groove 22; the depth of the other end of the second arc groove 22 is greater than the depth of one end of the second arc groove 22; the depth of one end of the second arc groove 22 is less than the depth of one end of the first arc groove 21. A waterproof medical device RF cable connector according to this embodiment, a first transition inclined surface 25 is provided in the middle of the first arc groove 21; a second transition inclined surface 26 is provided in the middle of the first straight groove 23; a third transition inclined surface 27 is provided in the middle of the second straight groove 24; a fourth transition inclined surface 28 is provided in the middle of the second arc groove 22. By providing each transition inclined surface, it is convenient for the fixing pin 72 to move in the first arc groove 21, the second arc groove 22, the first straight groove 23 and the second straight groove 24.

[0043] Specifically, for the waterproof medical device RF cable connector according to this embodiment, for the convenience of description, one end of the first arc groove 21 is defined as point A, one end of the first straight groove 23 is defined as point B, the other end of the second straight groove 24 is defined as point C, and the other end of the second arc groove 22 is defined as point D.

[0044] Before the connector 7 is installed with the connector head, the upper guide block 51 is located at the other end of the second upper arc groove 44, and the lower guide block 52 is located at the other end of the second lower arc groove 32. At this time, the arc-shaped sealing strip 5 is entirely retracted and accommodated in the accommodation cavity 15, and the driving pin 63 is located at point A at this time.

[0045] When installing the connector 7 with the connector head, insert the insertion table 71 into the insertion port 14 so that the fixing pin 72 is clamped with the tooth groove 41. Then, rotate the connector 7 in the forward direction. During the process of rotating the connector 7 in the forward direction, the driving pin 63 moves along the first arc groove 21, thereby driving the upper guide block 51 to move along the second upper arc groove 44 and the lower guide block 52 to move along the second lower arc groove 32. At the same time, the curve spring 45 is compressed until the driving pin 63 falls into point B. At this time, the upper guide block 51 moves to the other end of the first upper arc groove 43, and the lower guide block 52 moves to the other end of the first lower arc groove 31. The arc-shaped sealing strip 5 extends from the accommodation cavity 15 into the insertion port 14 and abuts against the outer wall of the insertion table 71, effectively playing a waterproof role. Then, loosen the connector 7. Under the reset action of the curve spring 45, the driving pin 63 moves along the first straight groove 23 until it falls into point C. Since the depth of point C is relatively deep, the curve spring 45 cannot continue to reset. At this time, the upper guide block 51 moves back to the middle of the first upper arc groove 43, and at this time, the connector 7 is firmly connected to the connector head.

[0046] When it is necessary to disassemble the connector head from the connector 7, continue to rotate the connector 7 in the forward direction. The driving pin 63 moves along the second straight groove 24 until it falls into point D. The upper guide block 51 moves back to the other end of the first upper arc groove 43. At this time, loosen the connector 7. Under the reset action of the curve spring 45, the driving pin 63 automatically moves along the second arc groove 22, thereby driving the upper guide block 51 to move along the first upper arc groove 43 and the lower guide block 52 to move along the first lower arc groove 31. Until the driving pin 63 falls into point A, at this time, the upper guide block 51 moves to the other end of the second upper arc groove 44, and the lower guide block 52 moves to the other end of the second lower arc groove 32, and the arc-shaped sealing strip 5 retracts back into the accommodation cavity 15 again.

[0047] For a waterproof medical device radio frequency line connector head described in this embodiment, a withdrawal boss 42 is provided on the inner wall of the annular driving ring 4; the distance between the withdrawal boss 42 and the center of the annular driving ring 4 is less than the distance between the tooth groove 41 and the center of the annular driving ring 4.

[0048] Specifically, when it is necessary to disassemble the connector head from the connector 7, continue to rotate the connector 7 forward, driving the driving pin 63 to move along the second straight groove 24 until it falls into point D. The upper guide block 51 moves back to the other end of the first upper arc groove 43. To facilitate the separation of the connector 7 from the connector head, continue to rotate the connector 7 forward. Since the driving pin 63 abuts against the groove wall at point D and cannot move, relative rotation occurs between the plugging table 71 and the annular driving ring 4 at this time, and the annular driving ring 4 cannot rotate. Until the fixing pin 72 rotates to the position where it exits the boss 42, the fixing pin 72 retracts into the plugging table 71. At this time, release the connector 7. Under the reset action of the curve spring 45, the driving pin 63 automatically moves along the second arc groove 22, thereby driving the upper guide block 51 to move along the first upper arc groove 43 and the lower guide block 52 to move along the first lower arc groove 31. Until the driving pin 63 falls into point A, at this time, the upper guide block 51 moves to the other end of the second upper arc groove 44, and the lower guide block 52 moves to the other end of the second lower arc groove 32. The arc-shaped sealing strip 5 retracts back into the accommodating cavity 15, and the connector 7 can be separated from the connector head.

[0049] In the waterproof medical device RF cable connector of this embodiment, the upper housing 12 and the lower housing 13 are detachably connected. Through the above setting, disassembly and assembly are facilitated.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
