DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides an embodiment of an electrical connector for an operating table, such as Figures 1 to 10 shown.

[0030] An electrical connector for an operating table, the connector 200 includes a male head 300 and a female head 400, the male head 300 can move toward the female head 400 along a first direction and plug into the female head 400, the first direction being the plugging direction of the male head 300 and the female head 400. The female head 400 includes a first outer cylinder 410 and a crimping piece, the first outer cylinder 410 is arranged along the first direction, the crimping piece includes a plurality of crimping strips, the plurality of crimping strips are evenly distributed around the first direction in the first outer cylinder 410, the crimping strips are elastic, and one end of the crimping strips in the first direction can revolve and rotate relative to the other end thereof around the first direction. The male head 300 includes a second outer cylinder 310 and a plurality of conductive members, the second outer cylinder 310 is arranged along the first direction, the conductive members include a plurality of conductive sheets, the plurality of conductive sheets are evenly distributed around the first direction in the second outer cylinder 310, the conductive sheets are elastic, and the plurality of conductive sheets can plug into each other with the plurality of crimping strips. A plugging channel is defined on the crimping piece. The crimping strip has a first state and a second state. When in the first state, the two ends of the crimping strip in the first direction are mutually offset in the first direction; at this time, the conductive member is restricted from entering the corresponding plug-in channel. When in the second state, the two ends of the crimping strip in the first direction overlap with each other in the first direction, and at this time, the conductive member is allowed to enter the corresponding plug-in channel. In the initial state, the crimping strip is in the first state. One end of the crimping strip can be rotated around the first direction relative to the other end thereof to switch the crimping strip between the first state and the second state.

[0031] In this embodiment, a crimping piece is provided on the female head 400, and it is matched with the conductive piece on the male head 300. When the male head 300 and the female head 400 are plugged, one end of the crimping strip is rotated around the first direction relative to the other end thereof, so that the two ends of the crimping strip are rotated from a state of being misaligned in the first direction to a state of being overlapped in the first direction, that is, the twisted crimping strip is rotated to be parallel to the first direction. At this time, the conductive piece can enter the corresponding plug-in channel, and during the process of plugging the conductive piece and the plug-in channel, the contact between the conductive piece and the plug-in channel is reduced, and wear is reduced. When one end of the crimping strip is rotated around the first direction relative to the other end thereof again, the two ends of the crimping strip in the first direction will be misaligned again in the first direction, so that multiple conductive sheets and multiple crimping strips are plugged together, and the multiple conductive sheets and multiple crimping strips after twisting and resetting can form a more stable connection, which is less likely to fall off when the connector 200 is subjected to external force, and the plug-in is more secure.

[0032] In this embodiment, two crimping parts and two conductive parts are provided. The two crimping parts arranged in sequence along the second direction are respectively referred to as the inner crimping part 420 and the outer crimping part 430. The inner crimping part 420 is located on the side of the outer crimping part 430 away from the first outer cylinder 410 in the second direction. The second direction is perpendicular to the first direction, and the second direction is the radial direction of the first outer cylinder 410. The multiple crimping strips of the inner crimping part 420 are referred to as the inner pressure strips 421, and the multiple crimping strips of the outer crimping part 430 are referred to as the outer pressure strips 431. The two conductive parts arranged in sequence along the second direction are respectively referred to as the inner conductive part and the outer conductive part. The inner conductive part is located on the side of the outer conductive part away from the second outer cylinder 310 in the first direction. The multiple conductive sheets of the inner conductive part are referred to as the inner conductive sheets 320, and the multiple conductive sheets of the outer conductive part are referred to as the outer conductive sheets 330. The plurality of inner conductive sheets 320 and the plurality of inner pressure strips 421 are sequentially arranged at intervals around the first direction, and the plurality of outer conductive sheets 330 and the plurality of outer pressure strips 431 are sequentially arranged at intervals around the first direction.

[0033] The two ends of the inner pressure strip 421 and the outer pressure strip 431 in the first direction are respectively referred to as the first end and the second end. The first end of the outer pressure strip 431 is located on the side of the second end thereof close to the male connector 300 in the first direction, the first ends of the plurality of outer pressure strips 431 are connected by an outer first ring 440, the outer first ring 440 is fixedly disposed in the first outer cylinder 410, and the second ends of the plurality of outer pressure strips 431 are connected by an outer second ring 450, the outer second ring 450 is disposed in the first outer cylinder 410 so as to be movable along the first direction and rotatable around the first direction. The first end of the inner pressure strip 421 is located at the side of the second end thereof close to the male connector 300 in the first direction, the first ends of the plurality of inner pressure strips 421 are connected through the inner first ring 460, the inner first ring 460 is rotatably disposed in the first outer cylinder 410 around the first direction, the second ends of the plurality of inner pressure strips 421 are connected through the inner second ring 470, the inner second ring 470 can move in the first direction with the outer second ring 450, and the outer second ring 450 can rotate around the first direction relative to the inner second ring 470. The second outer cylinder 310 can cause the outer second ring 450 to move in the first direction, and make the outer second ring 450 and the outer first ring 440 move away from each other in the first direction.

[0034] Alternatively, multiple crimping parts and multiple conductive parts are provided, and multiple crimping parts are sequentially arranged along the second direction in the first outer cylinder 410, and multiple conductive parts are sequentially arranged along the second direction in the second outer cylinder 310. By providing multiple crimping parts and multiple conductive parts, the stability of the male connector 300 and the female connector 400 after plugging can be further improved.

[0035] Further, the first end of the outer pressure strip 431 and the corresponding second end are sequentially arranged in the rotation direction of the outer second ring 450, and in the rotation direction of the outer second ring 450, the first end is located in front of the corresponding second end. Figure 7 The first end of the inner pressure strip 421 and the corresponding second end thereof are sequentially arranged in the rotation direction of the inner ring 460, and in the rotation direction of the inner ring 460, the first end is located behind the corresponding second end thereof. That is, the inner ring 460 is arranged in the direction of rotation of the inner ring 460. Figure 7 In other words, the inner pressure strip 421 and the outer pressure strip 431 have opposite torsional directions, and when the outer second ring 450 drives the second end of the outer pressure strip 431 to rotate, the direction of rotation is the same as the direction of rotation of the first end of the inner pressure strip 421 driven by the inner first ring 460.

[0036] In this embodiment, by providing two crimping parts and two conductive parts, when the second outer cylinder 310 causes the outer second ring 450 to move in the first direction and causes the outer second ring 450 and the outer first ring 440 to move away from each other in the first direction, the outer second ring 450 will drive the second end of the outer pressure strip 431 fixed thereto to move in the first direction, so that the outer pressure strip 431 tends to extend in the first direction. In order to realize the movement of the outer second ring 450 in the first direction, the outer second ring 450 will rotate around the first direction, so that the second end of the outer pressure strip 431 gradually rotates to a position where it overlaps with the first end corresponding to it in the first direction, thereby providing a margin for the movement of the outer second ring 450 in the first direction. And the movement of the outer two rings 450 can drive the inner two rings 470 to move synchronously. Similar to the rotation principle of the outer two rings 450, the movement of the inner two rings 470 will make the inner pressure strip 421 tend to stretch in the first direction. In order to realize the movement of the inner two rings 470 in the first direction, the inner ring 460 will rotate around the first direction, so that the first end of the inner pressure strip 421 gradually rotates to a position where it overlaps with the corresponding second end in the first direction, thereby providing a margin for the movement of the inner two rings 470 in the first direction.

[0037] By making the twisting directions of the inner pressure strip 421 and the outer pressure strip 431 opposite, the plugging effect of the two can be further improved after the inner pressure strip 421 and the inner conductive sheet 320 are plugged into each other and after the outer pressure strip 431 and the outer conductive sheet 330 are plugged into each other, so that the connection between the male connector 300 and the female connector 400 is more secure and the male connector 300 and the female connector 400 are prevented from loosening when subjected to external force.

[0038] In this embodiment, an inner limiting cylinder 481 and an outer limiting cylinder 482 are fixedly arranged in the first outer cylinder 410, and the inner pressure strip 421, the inner limiting cylinder 481, the outer pressure strip 431 and the outer limiting cylinder 482 are arranged in sequence in the second direction, and the inner pressure strip 421 is located on the side of the outer limiting cylinder 482 in the second direction away from the first outer cylinder 410. There are two plug-in channels, which are respectively referred to as the inner plug-in channel and the outer plug-in channel. The outer plug-in channel is defined by the inner limiting cylinder 481 and a plurality of outer pressure strips 431, and the inner plug-in channel is defined by a plurality of inner pressure strips 421.

[0039] In the initial state, the multiple outer pressure strips 431 can restrict the multiple outer conductive sheets 330 from entering the outer plug-in channel along the first direction, and the multiple inner pressure strips 421 can restrict the multiple inner conductive sheets 320 from entering the inner plug-in channel along the first direction. When the first end of each outer pressure strip 431 overlaps with the corresponding second end in the first direction, and the first end of each inner pressure strip 421 overlaps with the corresponding second end in the first direction, the multiple outer conductive sheets 330 can enter the outer plug-in channel along the first direction, and the multiple inner conductive sheets 320 can enter the inner plug-in channel along the first direction.

[0040] This embodiment is explained by setting an inner plug-in channel and an outer plug-in channel, taking the outer pressure strip 431 as an example. Since the first end of the outer pressure strip 431 and the corresponding second end thereof are sequentially arranged in the rotation direction of the outer second ring 450 in the initial state, the projection of the outer pressure strip 431 in the first direction will approach the central axis of the first outer cylinder 410 along the second direction, that is, the multiple outer pressure strips 431 uniformly distributed around the first direction will approach the central axis of the first outer cylinder 410 along the second direction, thereby restricting the outer conductive sheet 330 from entering the outer plug-in channel. The principle of the inner pressure strip 421 restricting the inner conductive sheet 320 from entering the inner plug-in channel is the same as the principle of the outer pressure strip 431 restricting the outer conductive sheet 330 from entering the outer plug-in channel, which will not be repeated here.

[0041] When the first end of each outer pressure strip 431 overlaps with its corresponding second end in the first direction and the first end of each inner pressure strip 421 overlaps with its corresponding second end in the first direction, the outer pressure strip 431 and the inner pressure strip 421 are both transformed from twisted to vertical, and in this process, the inner pressure strip 421 and the outer pressure strip 431 move along the second direction toward the side away from the central axis of the first outer cylinder 410, thereby increasing the volume of the inner plug-in channel and the outer plug-in channel, allowing the outer conductive sheet 330 to enter the outer plug-in channel along the first direction, and multiple outer conductive sheets 330 will be interspersed between multiple outer pressure strips 431, allowing the inner conductive sheet 320 to enter the inner plug-in channel along the first direction, and multiple inner conductive sheets 320 will be interspersed between multiple inner pressure strips 421.

[0042] In this embodiment, the second outer cylinder 310 includes a sliding sleeve 340 and a fixed sleeve 350, and the sliding sleeve 340 is sleeved with the fixed sleeve 350. A second terminal 360 is fixedly connected inside the fixed sleeve 350, the inner conductive sheet 320 is fixedly connected to the second terminal 360, the outer conductive sheet 330 is fixedly connected to the inner conductive sheet 320, a sliding space is defined between the second terminal 360 and the sliding sleeve 340, and a first elastic member 370 is arranged in the sliding space, the first elastic member 370 connects the second terminal 360 with the sliding sleeve 340, the first elastic member 370 is arranged along the first direction, and the first elastic member 370 is a spring. The sliding sleeve 340 can move along the first direction toward the side close to the female connector 400, and prompt the outer second ring 450 to move along the first direction. When the first ends of the outer pressure strip 431 and the inner pressure strip 421 rotate to positions where they overlap with their corresponding second ends in the first direction, the volume change of the sliding space is less than or equal to half of the total volume of the entire sliding space, leaving space for subsequent resetting.

[0043] In this embodiment, the sliding sleeve 340 includes an inner sliding cylinder 341 and an outer sliding cylinder 342, the inner sliding cylinder 341 and the outer sliding cylinder 342 are fixedly connected and coaxially arranged, the inner sliding cylinder 341 is located on the side of the outer sliding cylinder 342 close to the second terminal 360 in the second direction, and the sliding sleeve 340 moves along the first direction toward the side close to the female connector 400 to make the inner sliding cylinder 341 abut against the outer second ring 450, so that the outer sliding cylinder 342 is sleeved with the first outer cylinder 410. And when the inner sliding cylinder 341 abuts against the outer second ring 450, the inner sliding cylinder 341 can cause the outer second ring 450 to rotate around the first direction.

[0044] In this embodiment, a first terminal 480 is fixedly provided inside the first outer cylinder 410, and two ends of the outer limit cylinder 482 along the first direction are respectively fixedly connected to the outer first ring 440 and the first terminal 480, and a plurality of outer limit openings 484 are opened on the outer limit cylinder 482, and the plurality of outer limit openings 484 are evenly distributed on the outer limit cylinder 482 around the first direction, and a plurality of first bosses 451 are evenly distributed in the circumferential direction of the outer second ring 450, and the plurality of first bosses 451 are arranged in a one-to-one correspondence with the plurality of outer limit openings 484, and each first boss 451 is slidably installed in a corresponding outer limit opening 484 and extends out of the outer limit opening 484 along the second direction, and the first boss 451 can move in the corresponding outer limit opening 484 along the first direction, and can rotate in the corresponding outer limit opening 484 around the first direction. The sliding sleeve 340 moves along the first direction toward the female head 400 to make the inner slide 341 abut against the first boss 451 , and after the inner slide 341 abuts against the first boss 451 , the inner slide 341 can cause the first boss 451 to rotate around the first direction.

[0045] One end of the inner limit cylinder 481 along the first direction is fixedly connected to the first terminal 480, and the other end along the first direction is rotatably connected to the inner first ring 460. A plurality of inner limit openings 483 are provided on the inner limit cylinder 481, and the plurality of inner limit openings 483 are evenly distributed on the inner limit cylinder 481 around the first direction. A plurality of second bosses 471 are evenly distributed in the circumferential direction of the inner second ring 470, and the plurality of second bosses 471 are arranged in a one-to-one correspondence with the plurality of inner limit openings 483. Each second boss 471 is slidably installed in a corresponding inner limit opening 483, and the second boss 471 can move in the corresponding inner limit opening 483 along the first direction, and the inner limit opening 483 can limit the rotation of the corresponding second boss 471 around the first direction.

[0046] More specifically, an annular groove is provided on the inner end face of the outer second ring 450, and the second boss 471 extends out of the corresponding inner limit opening 483 along the second direction and is slidably installed in the annular groove, so that the inner second ring 470 can move in the first direction with the outer second ring 450, and the outer second ring 450 can rotate around the first direction relative to the inner second ring 470.

[0047] In this embodiment, a plurality of sealing strips 380 are provided on the inner circumferential wall surface of the outer slide 342, and the plurality of sealing strips 380 are sequentially provided along the first direction on the inner circumferential wall surface of the outer slide 342. By providing a plurality of sealing strips 380, the sealing performance between the outer slide 342 and the first outer cylinder 410 can be improved.

[0048] In another possible embodiment, the thickness of the inner conductive sheet 320 decreases in sequence in the first direction, and the thickness of the inner conductive sheet 320 close to the female connector 400 along the first direction is greater than the thickness of the inner conductive sheet 320 away from the female connector 400 along the first direction. The thickness of the outer conductive sheet 330 decreases in sequence in the first direction, and the thickness of the outer conductive sheet 330 close to the female connector 400 along the first direction is greater than the thickness of the outer conductive sheet 330 away from the female connector 400 along the first direction.

[0049] By further arranging that the thickness of the inner conductive sheet 320 is reduced in sequence in the first direction and the thickness of the outer conductive sheet 330 is reduced in sequence in the first direction, when the sealing strip 380 in contact with the first outer cylinder 410 becomes loose, the inner conductive sheet 320 can be further moved in the first direction toward the side close to the female head 400 under the action of the elastic force of the inner pressure strip 421 itself, and the outer conductive sheet 330 can be further moved in the first direction toward the side close to the female head 400 under the action of the elastic force of the outer pressure strip 431 itself, and then the sliding sleeve 340 is driven to move through the first elastic member 370, so that the sealing strip 380 on the outer sliding cylinder 342 forms a new seal with the first outer cylinder 410 to ensure the sealing effect.

[0050] In combination with the above embodiments, the specific working process is as follows:

[0051] During use, the operator holds the sliding sleeve 340 and moves it toward the side of the female connector 400. At this time, the multiple external pressure strips 431 will restrict the multiple external conductive sheets 330 from entering the external plug-in channel along the first direction, and the multiple internal pressure strips 421 will restrict the multiple internal conductive sheets 320 from entering the internal plug-in channel along the first direction. Therefore, after the external conductive sheets 330 and the internal conductive sheets 320 are restricted from moving further, the operator continues to push the sliding sleeve 340 to move along the first direction toward the side close to the female connector 400, which will cause the sliding sleeve 340 to move in the first direction relative to the fixed sleeve 350, thereby compressing the first elastic member 370 and reducing the sliding space. As the sliding sleeve 340 moves, after the inner sliding sleeve 341 moves to abut against the first boss 451 of the outer second ring 450, under the control of the operator, if the sliding sleeve 340 wants to continue to move and drive the outer second ring 450 to move, the outer second ring 450 will rotate around the first direction, so that the second end of the outer pressure strip 431 gradually rotates to a position that overlaps with the first end corresponding to it in the first direction. And synchronously drive the inner first ring 460 to rotate around the first direction, so that the first end of the inner pressure strip 421 gradually rotates to a position that overlaps with the second end corresponding to it in the first direction, so that the outer pressure strip 431 and the inner pressure strip 421 are both transformed from twisted to vertical, and no longer restrict the movement of the outer conductive sheet 330 and the inner conductive sheet 320.

[0052] After that, the operator releases his hand, and the first elastic member 370 causes the sliding sleeve 340 to reset. The outer pressure strip 431 and the inner pressure strip 421 will reset under the action of their own elastic force, and the outer pressure strip 431 after reset will reset and move along the second direction toward the central axis of the first outer cylinder 410 and twist together with the outer conductive sheet 330, and the inner pressure strip 421 will reset and move along the second direction toward the central axis of the first outer cylinder 410 and twist together with the inner conductive sheet 320, thereby completing the plug-in connection between the male connector 300 and the female connector 400.

[0053] When the male connector 300 and the female connector 400 need to be disassembled, the operator holds the sliding sleeve 340 again and moves it toward the female connector 400, so that the outer second ring 450 rotates around the first direction and moves along the first direction, so that the second end of the outer pressure strip 431 gradually rotates to a position that overlaps with the first end corresponding to it in the first direction. The inner first ring 460 is simultaneously driven to rotate around the first direction, so that the first end of the inner pressure strip 421 gradually rotates to a position that overlaps with the second end corresponding to it in the first direction, so that the outer pressure strip 431 and the inner pressure strip 421 are both transformed from twisting to vertical. In this process, the first elastic member 370 will automatically reset, and then the operator pulls the fixed sleeve 350 to move away from the female connector 400 along the first direction. The movement of the fixed sleeve 350 will drive the outer conductive sheet 330 and the inner conductive sheet 320 to move synchronously, so that the male connector 300 and the female connector 400 are separated.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
