[0050] The following Figures 1-9 describes the electromechanical device connector of the embodiments of the present invention.

[0051] An electromechanical device connector, comprising: a male head component; a female head component provided with an installation groove; a plugging component 500, including a first plugging terminal 510, a second plugging terminal 520, a crown spring 530, a first elastic unit 540, a transmission telescopic unit 560 and a fixing sleeve 570. The first plugging terminal 510 is arranged on the male head component; the second plugging terminal 520 is arranged on the female head component and located in the installation groove; the second plugging terminal 520 is provided with a plugging groove 521 for cooperating with the first plugging terminal 510; the crown spring 530 is located in the plugging groove 521 and fixedly connected to the side wall of the plugging groove 521; the inner diameter of the crown spring 530 is larger than the outer diameter of the first plugging terminal 510; a plurality of installation holes 5324 are circumferentially arranged on the crown spring 530; the first elastic unit 540 includes two first connecting pieces 541 and a plurality of first elastic strips 542; the plurality of first elastic strips 542 are circumferentially arranged outside the crown spring 530, and both ends of the first elastic strip 542 are respectively connected to a first connecting piece 541; one of the first connecting pieces 541 is fixedly connected to the second plugging terminal 520, and the other first connecting piece 541 is movably arranged in the plugging groove 521; the fixing sleeve 570 is fixed in the installation groove and a guiding member is arranged on the inner side wall of the fixing sleeve 570; the transmission telescopic unit 560 has the ability to elastically deform along the axial direction of the fixing sleeve 570; one end of the transmission telescopic unit 560 is cooperated with the guiding member, and the other end is used for passing through the installation hole 5324 and driving the first connecting piece 541 to rotate; the transmission telescopic unit 560 is provided with a guiding hole 5612 for the first plugging terminal 510 to pass through; when the first plugging terminal 510 is inserted into the plugging groove 521, the transmission telescopic unit 560 is compressed and rotates along the guiding member, and at this time, a plurality of first elastic strips 542 are twisted to squeeze the crown spring 530 to abut against the first plugging terminal 510.

[0052] When the male head component is connected to the female head component, a part of the first insertion terminal 510 is sleeved inside the fixed sleeve 570, and the other part passes through the transmission telescopic unit 560, the first connecting member 541 and the crown spring 530 and then abuts against the bottom of the insertion slot 521. During the process of inserting the first insertion terminal 510 into the insertion slot 521, it will abut against the transmission telescopic unit 560 and cause it to undergo axial deformation. While the transmission telescopic unit 560 axially displaces along the guide member, it will rotate around the axis of the fixed sleeve 570. Let the rotation direction of the transmission telescopic unit 560 be positive when the first insertion terminal 510 is inserted into the insertion slot 521. Since one first connecting member 541 is fixedly connected to the second insertion terminal 520 and the other first connecting member 541 is movably connected to the insertion slot 521, the transmission telescopic unit 560 passes through the mounting hole 5324 and drives the first connecting member 541 to rotate. At this time, the first connecting member 541 drives a plurality of first elastic strips 542 to twist, and the circular aperture formed by the plurality of first elastic strips 542 shrinks. The deformation area of the first elastic strips 542 is mainly concentrated in the middle of the first elastic strips 542, and the first elastic strips 542 press the crown spring 530 to closely adhere to the first insertion terminal 510. Because the crown spring 530 is made of a metal material and has conductivity, the first insertion terminal 510 can be electrically connected to the second insertion terminal 520 after contacting the crown spring 530. The first elastic strips 542 squeeze the side wall of the crown spring 530 to make it contact the outer side wall of the first insertion terminal 510, so that the contact between the first insertion terminal 510 and the crown spring 530 is relatively stable and the contact area is large, the resistance of the contact part is small, avoiding the generation of more heat, which is beneficial to the electrical connection between the first insertion terminal 510 and the second insertion terminal 520 through the crown spring 530; Since the transmission telescopic unit 560 has the ability to elastically deform axially along the fixed sleeve 570, when the first insertion terminal 510 is separated from the insertion slot 521, the compressed transmission telescopic unit 560 restores its shape and rotates reversely along the guide member. At this time, the first connecting member 541 drives the twisted first elastic strips 542 to return to their original state, and the crown spring 530 no longer contacts the side wall of the first insertion terminal 510, so that the first insertion terminal 510 will not be worn by the crown spring 530 during the process of separating from the insertion slot 521, extending the service life of the first insertion terminal 510.

[0053] After the first connecting member 541 rotates by a small angle, the first elastic strips 542 can twist. The rotation angle of the first connecting member 541 is one of the influencing factors for the radial deformation degree of the first elastic strips 542. The mounting hole 5324 can be fan-shaped, and the radian of the mounting hole 5324 can be set as required.

[0054] The first plug-in terminal 510 may include a first cylinder 511 and a second cylinder 512 with different diameters. The first cylinder 511 cooperates with the fixed sleeve 570, and the second cylinder 512 passes through the transmission telescopic unit 560, the first connecting member 541, and the crown spring 530, and finally abuts against the bottom of the plug-in slot 521 to contact the second plug-in terminal 520. The first cylinder 511 is the main part for axially pressing the transmission telescopic unit 560.

[0055] In one embodiment, the crown spring 530 includes a first mounting member 532, a second mounting member 533, and a plurality of clamping strips 531. The first mounting member 532 is connected to the side wall of the plug-in slot 521. The second mounting member 533 is located at the bottom of the plug-in slot 521 and is connected to the second plug-in terminal 520. The first mounting member 532 is provided with a plug-in hole for the first plug-in terminal 510 to pass through and a plurality of circumferentially arranged mounting holes 5324. The plurality of clamping strips 531 are arranged circumferentially along the first mounting member 532 or the second mounting member 533. One end of the clamping strip 531 is connected to the first mounting member 532, and the other end of the clamping strip 531 is connected to the second mounting member 533.

[0056] The first mounting member 532 and the second mounting member 533 are coaxially arranged. The first mounting member 532 may include an annular body 5321, a cylindrical body 5322, and a plurality of partition plates 5323. The annular body 5321 and the cylindrical body 5322 are coaxial. The plurality of partition plates 5323 are circumferentially arranged outside the cylindrical body 5322. One end of the partition plate 5323 is connected to the annular body 5321, and the other end is connected to the cylindrical body 5322. The gap between adjacent partition plates 5323 forms the mounting hole 5324. The inner hole of the cylindrical body 5322 is the plug-in hole. One end of the clamping strip 531 is connected to the partition plate 5323, and the other end is connected to the second mounting member 533. The middle of the second mounting member 533 is provided with a through hole for the first plug-in terminal 510 to pass through.

[0057] The surface of the clamping strip 531 close to the first plug-in terminal 510 may be an arc surface to fit the outer surface of the first plug-in terminal 510.

[0058] In one embodiment, the transmission telescopic unit 560 includes a synchronizing ring 561, a synchronizing rod 562, a spring 563, and a transmission member 564. The synchronizing ring 561 is located in the fixed sleeve 570 and cooperates with the guiding member. The synchronizing ring 561 is provided with a connecting hole 5611 and a guiding hole 5612. One end of the spring 563 is connected to the synchronizing ring 561, and the other end of the spring 563 is connected to the transmission member 564. The synchronizing rod 562 is arranged on the transmission member 564 and passes through the connecting hole 5611. The transmission member 564 is used to drive the first connecting member 541 to rotate.

[0059] A groove can be provided on the end surface of the synchronizer ring 561 close to the transmission member 564 to install the spring 563. One end of the spring 563 can be fixed to the transmission member 564, and the other end can abut against the bottom of the groove of the synchronizer ring 561. The groove can also limit the radial movement of the spring 563.

[0060] There can be multiple synchronization rods 562 and they are circumferentially arranged on the transmission member 564, and the number of the connection holes 5611 corresponds to the number of the synchronization rods 562. When the synchronization rod 562 passes through the synchronization ring 561, the synchronization ring 561 rotates to drive the transmission member 564 to rotate together.

[0061] The guide member is arranged on the inner wall of the fixed sleeve 570. The guide member can be a groove, a protrusion, a ramp or other mechanical structure, which is not limited here. The synchronous ring 561 can be provided with a corresponding structure cooperating with the guide member so that the synchronous ring 561 can rotate along the guide member after being axially pressurized.

[0062] In one embodiment, one of the first connecting members 541 is fixedly connected to the second mounting member 533, and the other first connecting member 541 is located between the transmission member 564 and the first mounting member 532 and is rotatably disposed in the plug-in slot 521;

[0063] The first connecting member 541 is annular and has a plurality of first baffles 543 arranged circumferentially thereon; the two ends of the first elastic strip 542 are respectively connected to the two first baffles 543; a plurality of toggle plates 565 are arranged circumferentially thereon at one end of the transmission member 564 away from the synchronization rod 562, and the toggle plates 565 pass through the mounting hole 5324 and are located between two adjacent first baffles 543.

[0064] The inner diameter of the hole surrounded by the plurality of first elastic strips 542 is larger than the outer diameter of the hole surrounded by the plurality of clamping strips 531. The cross section of the first elastic strip 542 may be circular. The first elastic strip 542 itself has elastic deformation capability, so that the first elastic strip 542 can return to its original shape after multiple twists.

[0065] When the first plug terminal 510 is inserted into the plug slot 521, the synchronous ring 561 rotates forward, and the transmission member 564 applies force to the first baffle plate 543 through the toggle plate 565 to drive the first connecting member 541 to rotate. At this time, the first elastic strip 542 is twisted and the first elastic strip 542 is stretched; when the first plug terminal 510 is separated from the plug slot 521, the first elastic strip 542 recovers and begins to shrink to restore its original length. Multiple first elastic strips 542 jointly drive the first connecting member 541 to rotate relative to the plug slot 521, and the first baffle plate 543 applies pressure to the toggle plate 565 and drives the toggle plate 565 to rotate in the opposite direction, so that the transmission member 564 rotates back to the initial position.

[0066] In the initial state, the toggle plate 565 can fit the first baffle plate 543. The number of the first baffle plates 543 and the number of the toggle plates 565 are the same as the number of the mounting holes 5324, that is, each mounting hole 5324 corresponds to one first baffle plate 543 and one toggle plate 565.

[0067] The length of the toggle plate 565 in the axial direction of the inserting slot 521 may be the sum of the thicknesses of the first mounting member 532 and the first connecting member 541 .

[0068] In one embodiment, the plug assembly 500 further includes a second elastic unit 550; the second elastic unit 550 includes two second connecting members 551 and a plurality of second elastic strips 552;

[0069] The two second connecting members 551 are located between the two first connecting members 541. The second connecting member 551 near the bottom of the plug-in slot 521 is fixedly connected to the first connecting member 541. The other second connecting member 551 is rotatably disposed in the plug-in slot 521. The second connecting member 551 is annular and circumferentially provided with a plurality of second baffles 553. The second baffles 553 are arranged alternately with the first baffles 543. The toggle plate 565 is located between the first baffle 543 and the second baffle 553.

[0070] A plurality of second elastic strips 552 are circumferentially arranged on the outer side of the crown spring 530 , and both ends of the first elastic strip 542 are respectively connected to a second baffle 553 ;

[0071] The first baffle plate 543 and the second baffle plate 553 are respectively located on both sides of the toggle plate 565 and are both fitted with the toggle plate 565, and each mounting hole 5324 corresponds to a first baffle plate 543 and a second baffle plate 553. When the first plug-in terminal 510 is inserted into the plug-in slot 521 for the first time, the transmission telescopic unit 560 is compressed and rotates in the positive direction along the guide member, and at this time, the plurality of first elastic strips 542 twist and squeeze the crown spring 530 to abut against the first plug-in terminal 510; when the first plug-in terminal 510 is separated from the plug-in slot 521 for the first time, the transmission telescopic unit 560 is extended and rotates in the opposite direction along the guide member, and at this time, the plurality of first elastic strips 542 are restored to their original state and away from the first plug-in terminal 510.

[0072] When the first plug terminal 510 is inserted into the plug slot 521 for the second time, the transmission telescopic unit 560 is compressed and rotates in the opposite direction along the guide member, and the plurality of second elastic strips 552 twist and squeeze the crown spring 530 to abut against the first plug terminal 510. When the first plug terminal 510 is separated from the plug slot 521 for the second time, the transmission telescopic unit 560 is extended and rotates in the positive direction along the guide member, and the plurality of second elastic strips 552 are restored to their original state and away from the first plug terminal 510.

[0073] It should be noted that the time interval between the first insertion of the first plug terminal 510 into the plug slot 521 and the second insertion of the first plug terminal 510 into the plug slot 521 is relatively long. After the first plug terminal 510 and the second plug terminal 520 are connected for a long time for the first time, there may be a scenario where it is necessary to disconnect the first plug terminal 510 and the second plug terminal 520. For example, when an operator needs to perform a power-off operation for the maintenance of the electromechanical equipment, before the power-off, the first elastic strip 542 twists and presses the crown spring 530 against the first plug terminal 510, and at this time, the second elastic strip 552 does not deform; after the power-off, when the first plug terminal 510 and the second plug terminal 520 are connected, the first elastic strip 542 does not deform, and the second elastic strip 552 twists and presses the crown spring 530 against the first plug terminal 510. The first elastic strip 542 and the second elastic strip 552 are used alternately. During the plugging and unplugging process of the first plug terminal 510, the second elastic strip 552 and the first elastic strip 542 do not interfere with each other.

[0074] In the plugging and unplugging states of the first plug terminal 510 and the second plug terminal 520, the first elastic unit 540 and the second elastic unit 550 alternately squeeze the crown spring 530 to abut against the first plug terminal 510, and the first elastic strip 542 and the second elastic strip 552 are used alternately, so that the service life of the elastic strip is relatively long, thereby prolonging the service life of the electromechanical equipment connector.

[0075] In one embodiment, the guiding member is a guiding groove 571. The guiding groove 571 includes a first groove 5711, a second groove 5712, a third groove 5713, and a fourth groove 5714 that are sequentially connected end to end to form a closed loop, and the connection parts are a second reversing end 5716, a third reversing end 5717, a fourth reversing end 5718, and a first reversing end 5715 in sequence;

[0076] The first groove 5711 communicates with the fourth groove 5714 to form a first V-shaped groove; the second groove 5712 and the third groove 5713 communicate to form a second V-shaped groove; the openings of the first V-shaped groove and the second V-shaped groove both face the second plug terminal 520;

[0077] The synchronous ring 561 is provided with a guiding block 5613 that cooperates with the guiding groove 571; when the guiding block 5613 is located at the first reversing end 5715 or the third reversing end 5717, the first plug terminal 510 is disengaged from the plug slot 521; when the guiding block 5613 is located at the second reversing end 5716 or the fourth reversing end 5718, the first plug terminal 510 is inserted into the plug slot 521 and abuts against the bottom of the plug slot 521.

[0078] The working process of the electromechanical equipment connector of the present invention:

[0079] Before the first plug-in terminal 510 is inserted into the plug-in slot 521 for the first time, the guide block 5613 is located at the first reversing end 5715; when the first plug-in terminal 510 is inserted into the plug-in slot 521 for the first time, the first plug-in terminal 510 abuts against the synchronous ring 561 and moves axially. At this time, the guide block 5613 moves from the first reversing end 5715 along the first groove 5711 to the second reversing end 5716, and the synchronous ring 561 rotates forward and drives the transmission member 564 to rotate through the synchronous rod 562, and the spring 563 between the synchronous ring 561 and the transmission member 564 is compressed, and the transmission member 564 drives the first connecting member 541 to rotate forward through the toggle plate 565 and the first baffle plate 543, and the plurality of first elastic strips 542 are twisted and elongated, and the circular holes surrounded by the plurality of first elastic strips 542 shrink, and the first elastic strips 542 radially press the clamping strip 531 to make it abut against the first plug-in terminal 510, so that the first plug-in terminal 510 and the second plug-in terminal 520 are conductively connected. Until the end of the first plug-in terminal 510 abuts against the bottom of the plug-in slot 521 , the guide block 5613 moves to the second reversing end 5716 .

[0080] When the first plug terminal 510 is separated from the plug slot 521 for the first time, the spring 563 begins to reset and stretch and drives the synchronizer ring 561 to move toward the male component. At this time, the guide block 5613 moves from the second reversing end 5716 along the second slot 5712 to the third reversing end 5717, and the synchronizer ring 561 rotates in the opposite direction and drives the transmission member 564 to reverse. At this time, the toggle plate 565 does not apply a positive tangential force to the first baffle 543. The multiple first elastic strips 542 shorten and return to their original length, and the first elastic strips 542 drive the first connector 541 to rotate in the opposite direction until it rotates to the initial position of the first connector 541.

[0081] Similarly, when the first plug-in terminal 510 is inserted into the plug-in slot 521 for the second time, the first plug-in terminal 510 abuts against the synchronous ring 561 and moves axially. At this time, the guide block 5613 moves from the third reversing end 5717 along the third slot 5713 to the fourth reversing end 5718, and the synchronous ring 561 rotates in the opposite direction and drives the transmission member 564 to rotate through the synchronous rod 562. The spring 563 between the synchronous ring 561 and the transmission member 564 is compressed, and the transmission member 564 drives the second connecting member 551 to rotate in the opposite direction through the toggle plate 565 and the second baffle plate 553. The multiple second elastic strips 552 are twisted and elongated, and the circular holes surrounded by the multiple second elastic strips 552 shrink. The second elastic strips 552 radially press the clamping strip 531 to make it abut against the first plug-in terminal 510, so that the first plug-in terminal 510 and the second plug-in terminal 520 are conductively connected. Until the end of the first plug-in terminal 510 abuts against the bottom of the plug-in slot 521 , the guide block 5613 moves to the fourth reversing end 5718 .

[0082] When the first plug terminal 510 is disengaged from the plug slot 521 for the second time, the spring 563 begins to reset and stretch and drives the synchronizer ring 561 to move toward the male assembly. At this time, the guide block 5613 moves from the fourth reversing end 5718 along the fourth slot 5714 to the first reversing end 5715, and the synchronizer ring 561 rotates forward and drives the transmission member 564 to rotate forward. At this time, the toggle plate 565 does not apply a reverse tangential force to the second baffle 553. The multiple second elastic strips 552 shorten and return to their original lengths, and the second elastic strips 552 drive the second connector 551 to rotate in the reverse direction until it rotates to the initial position of the second connector 551.

[0083] The axial direction of the fixed sleeve 570 is taken as the baseline; since the long sides of the first groove 5711, the second groove 5712, the third groove 5713 and the fourth groove 5714 are arranged at an angle to the baseline of the fixed sleeve 570, when the guide block 5613 moves along the guide groove 571, the circumferential position of the guide block 5613 changes, thereby driving the synchronizer ring 561 to rotate relative to the fixed sleeve 570.

[0084] In one embodiment, the first groove 5711 includes a first limiting groove 57111 and a second limiting groove 57112; the third groove 5713 includes a third limiting groove 57131 and a fourth limiting groove 57132; the axial direction of the fixing sleeve 570 is taken as the baseline;

[0085] The first limiting groove 57111 is connected to the fourth groove 5714; the second limiting groove 57112 is connected to the second groove 5712; the third limiting groove 57131 is connected to the second groove 5712; the fourth limiting groove 57132 is connected to the fourth groove 5714; the long sides of the first limiting groove 57111 and the third limiting groove 57131 are both parallel to the baseline.

[0086] When the first plug-in terminal 510 is not inserted into the plug-in slot 521, the guide block 5613 is located at the first reversing end 5715 and in the first limit groove 57111, or the guide block 5613 is located at the third reversing end 5717 and in the third limit groove 57131. Therefore, when the first plug-in terminal 510 is inserted into the plug-in slot 521, the guide block 5613 will not move from the first reversing end 5715 to the fourth groove 5714, nor will it move from the third reversing end 5717 to the second groove 5712.

[0087] When the first plug-in terminal 510 abuts against the bottom of the plug-in slot 521, the guide block 5613 is located at the second reversing end 5716 and in the second slot 5712, or the guide block 5613 is located at the fourth reversing end 5718 and in the fourth slot 5714. Therefore, when the first plug-in terminal 510 is disengaged from the plug-in slot 521, the guide block 5613 will not move from the second reversing end 5716 to the first slot 5711, nor will it move from the fourth reversing end 5718 to the third slot 5713.

[0088] In one embodiment, the number of the guiding grooves 571 is multiple and they are circumferentially arranged on the fixed sleeve 570; the number of the guiding blocks 5613 is multiple and they are circumferentially arranged on the synchronizing ring 561.

[0089] The multiple guiding blocks 5613 drive the synchronizing ring 561 to rotate simultaneously, so that the force on the synchronizing ring 561 is relatively uniform, and the phenomenon of the synchronizing ring 561 tilting is not likely to occur, making the rotation of the synchronizing ring 561 relatively stable.

[0090] In one embodiment, the male head assembly includes a male head body 100 and a first connection end 300 which are connected to each other; the female head assembly includes a female head body 200 and a second connection end 400 which are connected to each other;

[0091] The first plug-in terminal 510 is arranged on the first connection end 300; the second connection end 400 is provided with an installation groove, and the second plug-in terminal 520 is arranged on the second connection end 400; the first connection end 300 and the second connection end 400 are detachably connected.

[0092] After the first connection end 300 and the second connection end 400 are connected, the first plug-in terminal 510 and the second plug-in terminal 520 are in closer contact. Prevent the first plug-in terminal 510 from disengaging from the plug-in slot 521.

[0093] The first connection end 300 is provided with a convex block 301, and the second connection end 400 is provided with a buckle 401 that cooperates with the convex block 301. The buckle 401 has a card slot that cooperates with the convex block 301. The first connection end 300 and the second connection end 400 are connected by using the buckle 401 structure, which has a simple structure and is convenient to operate.

[0094] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0095] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of this application should be subject to the appended claims.
