[0002] Currently, in the field of electronic products, when powering on an electronic product or transmitting signals, wireless and wired methods are often used, and wired electrical connections are more common. When using a wired method for electrical connection, a mating structure of plugging a plug into a socket is generally adopted. One of the plug and the socket is electrically connected to a power source, and the other is connected to a product. During use, the plug and the socket are plugged together.

[0003] The inventor has found through research that the existing mating structure of the plug and the socket has the following disadvantages:

[0004] The connection firmness between the plug and the socket is poor. Summary of the Invention

[0005] An object of the present invention is to provide a charging and discharging waterproof connector, which can improve the connection firmness between the plug and the socket.

[0006] The embodiments of the present invention are implemented as follows:

[0007] The embodiments of the present invention provide a charging and discharging waterproof connector, which includes:

[0008] A first plug-in member, a second plug-in member, an elastic reset member, and a clamping protrusion. The clamping protrusion is slidably connected to the first plug-in member in the circumferential direction of the first plug-in member. The elastic reset member is disposed on the first plug-in member and is used to abut against the clamping protrusion and cause the clamping protrusion to have a tendency to rotate relative to the first plug-in member along a first preset direction; the second plug-in member is provided with a clamping groove, and at least one of the clamping protrusion and the second plug-in member is provided with a guiding inclined surface;

[0009] When the first plug-in member and the second plug-in member approach each other, the clamping protrusion can rotate along a second preset direction opposite to the first preset direction under the guidance of the guiding inclined surface, and after the clamping protrusion or the clamping groove disengages from the guiding inclined surface, the clamping protrusion rotates along the first preset direction under the action of the elastic reset member to be clamped in the clamping groove, so as to limit the first plug-in member and the second plug-in member from moving away from each other.

[0010] In an alternative embodiment, the first plug-in member is set as a plug, and the second plug-in member is set as a socket electrically connected to the plug.

[0011] In an alternative embodiment, the number of the clamping protrusions is set to be multiple, and the multiple clamping protrusions are arranged at intervals in the circumferential direction of the first plug-in member;

[0012] There are multiple clamping grooves, and the multiple clamping grooves are clamped and matched with the multiple clamping protrusions in a one-to-one correspondence.

[0013] In an optional embodiment, the engaging protrusion is provided with a first guiding slope, and the second connector is provided with a second guiding slope; when the first connector and the second connector approach each other, the first guiding slope and the second guiding slope abut against each other and guide the engaging protrusion to be inserted into the engaging groove.

[0014] In an optional embodiment, the charging and discharging waterproof connector also includes a sleeve, which is arranged outside the first connector and is detachably connected to the first connector, and the snap-in protrusion is provided on the inner wall of the sleeve; the second connector can be plugged into the sleeve.

[0015] In an optional embodiment, the sleeve and the first connector are detachably connected via a threaded structure.

[0016] In an optional embodiment, the sleeve is detachably connected to the first connector via a snap-fit structure.

[0017] In an optional embodiment, the sleeve is provided with a limiting protrusion, the first connector is provided with a limiting groove and an inlet and outlet penetrating the side wall of the limiting groove and communicating with the limiting groove, and the limiting groove extends along the circumference of the first connector;

[0018] When the sleeve is sleeved outside the first connector and the limiting protrusion is aligned with the inlet and outlet in the axial direction of the first connector, the limiting protrusion can pass through the inlet and outlet and enter the limiting groove. The sleeve is rotated so that the limiting protrusion and the inlet and outlet are at least partially offset in the axial direction of the first connector, thereby preventing the sleeve from detaching from the first connector in the axial direction of the first connector.

[0019] In an optional embodiment, a blocking member is further provided on the first connector, and the blocking member is used to abut against the limiting protrusion when the sleeve rotates along the first preset direction to limit the rotation angle of the sleeve.

[0020] In an optional embodiment, the charging and discharging waterproof connector also includes a first magnet and a second magnet, the first magnet is connected to the first connector, and the second magnet is connected to the second connector. When the first connector and the second connector are plugged in, the first magnet and the second magnet are magnetically attracted.

[0021] The beneficial effects of the embodiments of the present invention are:

[0022] In summary, for the charging and discharging waterproof connector provided in this embodiment, when the first plug-in part and the second plug-in part approach each other to achieve plugging and mating, the clamping protrusion can rotate relative to the first plug-in part along the second preset direction under the guidance of the guiding inclined surface, and drive the elastic resetting part to move, so that the elastic resetting part generates an elastic force for restoring deformation; and when the clamping protrusion or the clamping groove disengages from the guiding inclined surface, the clamping protrusion rotates along the first preset direction under the elastic force of the elastic resetting part, so that the clamping protrusion is snapped into the clamping groove. The clamping and mating structure of the clamping protrusion and the clamping groove can prevent the first plug-in part and the second plug-in part from moving away from each other, thereby improving the firmness after the first plug-in part and the second plug-in part are plugged together. During the plugging and mating process, the two are not easily separated and are not easily powered off, and the use is safe and reliable.

[0023] At the same time, when the first plug-in part and the second plug-in part are plugged and mated, they can be aligned and then plugged. The clamping protrusion can be automatically snapped into the clamping groove under the action of the elastic resetting part, and the operation is convenient and fast.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Please refer to Figures 1-10 , this embodiment provides a charge-discharge waterproof connector. When the charge-discharge waterproof connector is in an assembled state, the connection structure between the plug and the socket is firm, and the two are not easily separated, and the use safety is high.

[0044] It should be noted that the charge-discharge waterproof connector can be applied to aspects such as light transportation, new energy, electric vehicles, electric forklifts, and waterproof connectors for electromechanical equipment.

[0045] Please refer to Figures 1-4 , in this embodiment, the charge-discharge waterproof connector includes a first plug-in member 100, a second plug-in member 200, an elastic reset member, and a clamping protrusion 400. The clamping protrusion 400 is slidably connected to the first plug-in member 100 in the circumferential direction of the first plug-in member 100. The elastic reset member is arranged on the first plug-in member 100 and is used to abut against the clamping protrusion 400 and make the clamping protrusion 400 have a tendency to rotate relative to the first plug-in member 100 along a first preset direction; the second plug-in member 200 is provided with a clamping groove 220, and at least one of the clamping protrusion 400 and the second plug-in member 200 is provided with a guiding inclined surface;

[0046] When the first connector 100 and the second connector 200 approach each other, the latching projection 400 can rotate along a second preset direction opposite to the first preset direction under the guidance of the guiding inclined surface, and after the latching projection 400 or the latching groove 220 disengages from the guiding inclined surface, the latching projection 400 rotates along the first preset direction under the action of the elastic reset member to be latched in the latching groove 220, thereby restricting the first connector 100 and the second connector 200 from moving away from each other and making it difficult for the first connector 100 and the second connector 200 to separate.

[0047] It should be noted that the first connector 100 and the second connector 200 are a plug and a socket that cooperate with each other. For example, when the first connector 100 is a plug, the second connector 200 is a socket; when the first connector 100 is set as a socket, the second connector 200 is set as a plug. In this embodiment, the first connector 100 is taken as an example of a plug and the second connector 200 is taken as an example of a socket for description.

[0048] In other words, a plurality of conductive posts 110 are provided on the first connector 100. Please refer to Figure 7 , a plurality of conductive slots 210 are provided on the second connector 200, and the plurality of conductive posts 110 are inserted into the plurality of conductive slots 210 in a one-to-one correspondence, and the paired conductive posts 110 are electrically connected to the conductive slots, playing a role in transmitting electricity. Obviously, after the plug and the socket are inserted, they can play a role in transmitting signals.

[0049] It should be noted that the conductive slot 210 can be a crown spring hole.

[0050] In this embodiment, when the first connector 100 and the second connector 200 approach each other to achieve plugging and mating, the latching projection 400 can rotate relative to the first connector along the second preset direction under the guidance of the guiding inclined surface, and drive the elastic reset member to move, so that the elastic reset member generates an elastic force for restoring deformation; and when the latching projection 400 or the latching groove 220 disengages from the guiding inclined surface, the latching projection 400 rotates along the first preset direction under the elastic force of the elastic reset member, so that the latching projection 400 is snapped into the latching groove 220. The latching and mating structure of the latching projection 400 and the latching groove 220 can prevent the first connector 100 and the second connector 200 from moving away from each other, thereby improving the firmness after the first connector 100 and the second connector 200 are plugged together. During the plugging and mating process, the two are not easy to separate and are not easy to cause power failure, and the use is safe and reliable.

[0051] At the same time, when the first connector 100 and the second connector 200 are plugged and mated, the first connector 100 and the second connector 200 can be aligned and then plugged. The latching projection 400 can be automatically snapped into the latching groove 220 under the action of the elastic reset member, and the operation is convenient and fast.

[0052] Please refer toFigure 5 , in this embodiment, optionally, a limiting groove 120 is provided on the outer peripheral surface of the first plug-in member 100. The limiting groove 120 extends along the circumferential direction of the first plug-in member 100. Among them, both the first preset direction and the second preset direction are in the circumferential direction of the first plug-in member 100. The limiting groove 120 has a first groove wall and a second groove wall in the axial direction of the first plug-in member 100. The first groove wall is close to one end of the first plug-in member 100 where it is plugged into the second plug-in member 200. An inlet / outlet 130 is provided on the first groove wall, and the inlet / outlet 130 communicates with the limiting groove 120.

[0053] , optionally, a first blocking member 140 and a second blocking member 160 are further provided on the outer peripheral surface of the first plug-in member 100. The first blocking member 140 and the second blocking member 160 are respectively arranged on both sides of the extending direction of the limiting groove 120. The first blocking member 140 and the second blocking member 160 can both be two groove walls of the limiting groove 120 in its extending direction.

[0054] , optionally, an intermediate blocking member 150 is provided between the first blocking member 140 and the second blocking member 160. The intermediate blocking member 150 is an inclined wall having an angle with the groove bottom of the limiting groove 120, and the distance between the intermediate blocking member 150 and the groove bottom of the limiting groove 120 gradually increases in the direction away from the first blocking member 140. There is a spacing between the intermediate blocking member 150 and the second blocking member 160.

[0055] It should be noted that one side surface of the first blocking member 140 facing the second blocking member 160 is in the same plane as one side wall of the inlet / outlet 130. In other words, the structure entering the limiting groove 120 from the inlet / outlet 130 directly abuts against the first blocking member 140, thereby restricting the structure entering the inlet / outlet 130 from rotating towards the first blocking member 140 in the extending direction of the limiting groove 120. There is a spacing between the second blocking member 160 and the first blocking member 140, so that the structure entering the limiting groove 120 from the inlet / outlet 130 can rotate a set distance relative to the limiting groove 120 towards the second limiting member. When it rotates until it abuts against the second limiting member, the rotation stops; at the same time, during the rotation of the sleeve 500 along the second preset direction, the structure entering from the inlet / outlet 130 can cross over the intermediate blocking member 150 and be located between the intermediate blocking member 150 and the second limiting member, and the sleeve 500 can only rotate back and forth between the intermediate blocking member 150 and the second limiting member.

[0056] In addition, the number of the limiting grooves 120 is multiple, and an inlet / outlet 130, a first limiting member and a second limiting member arranged at intervals are provided on each limiting groove 120. For example, in this embodiment, the number of the limiting grooves 120 is two.

[0057] Please refer to Figure 5In this embodiment, optionally, the charging and discharging waterproof connector further includes a sleeve 500, which is sleeved outside the first connector 100 and can be removed from the outside of the first connector 100. In other words, the sleeve 500 is detachably connected to the first connector 100.

[0058] Optionally, the limiting protrusion 510 is provided on the inner wall of the sleeve 500, the number of the limiting protrusions 510 corresponds to the number of the limiting grooves 120, and multiple limiting protrusions 510 correspond one-to-one to multiple inlets and outlets 130, and each limiting protrusion 510 can enter the limiting groove 120 from the corresponding inlet and outlet 130.

[0059] See also Figure 5 and Figure 6 When the sleeve 500 is sleeved on the outside of the first connector 100, the multiple limiting protrusions 510 on the sleeve 500 correspond one-to-one to the multiple inlets and outlets 130 on the first connector 100 and are aligned in the axial direction of the first connector 100. At this time, the sleeve 500 and the first connector 100 are brought close to each other, and the limiting protrusions 510 enter the limiting grooves 120 from the corresponding inlets and outlets 130. Then, the sleeve 500 is rotated along the second preset direction so that the limiting protrusions 510 can pass over the intermediate blocking member 150, and when the rotation continues, the limiting protrusions 510 can abut against the second blocking member 160, and the second limiting member limits the rotation angle of the limiting protrusions 510. And because the thickness of the intermediate barrier 150 gradually increases from the bottom of the limiting groove 120 in the direction away from the first barrier 140, the limiting protrusion 510 can cause the intermediate barrier 150 to produce elastic deformation when it abuts against the intermediate barrier 150 and after passing over the intermediate barrier 150, the intermediate barrier 150 restores the deformation, so that the limiting protrusion 510 cannot rotate along the first preset direction and pass over the intermediate barrier 150. At this point, the limiting protrusion 510 is restricted between the intermediate barrier 150 and the second barrier 160.

[0060] It should be noted that the sleeve 500 and the first connector 100 are rotationally coupled and connected by a damping structure, which restricts the free rotation of the sleeve 500. The sleeve 500 must overcome the damping under the action of an external force to rotate. When the sleeve 500 is not subjected to external forces, the position of the sleeve 500 and the first connector 100 remains relatively stable and is not easily rotated.

[0061] Meanwhile, since the first blocking member 140 is provided at the inlet and outlet 130, the rotation direction of the sleeve 500 relative to the first plug-in member 100 is restricted after the limiting protrusion 510 enters the limiting groove 120, preventing the sleeve 500 from rotating in the first preset direction and improving the accuracy of operating the sleeve 500. And when the sleeve 500 rotates by a set angle in the second preset direction, the limiting protrusion 510 and the inlet and outlet 130 are at least partially staggered in the axial direction of the first plug-in member 100. At this time, the limiting protrusion 510 is blocked by the first groove wall of the limiting groove 120 and will not enter the inlet and outlet 130 along the axial direction of the first plug-in member 100, realizing the relative fixation of the sleeve 500 and the first plug-in member 100 in the axial direction and the circumferential direction of the first plug-in member 100. And due to the action of the intermediate blocking member 150, the limiting protrusion 510 is restricted between the intermediate blocking member 150 and the second blocking member 160, preventing the sleeve 500 from separating from the first plug-in member 100.

[0062] Optionally, the clamping protrusion 400 is provided on the sleeve 500, and the clamping protrusion 400 has a first guiding inclined surface 410. Meanwhile, the elastic reset member is provided on the sleeve 500 and is connected to the clamping protrusion 400, so that the clamping protrusion 400 has a tendency to rotate in the first preset direction.

[0063] When the sleeve 500 is sleeved outside the first plug-in member 100 and rotates by a set angle in the second preset direction to lock the sleeve 500 and the first plug-in member 100, that is, the installation of the clamping protrusion 400 and the first plug-in member 100 is completed, the clamping protrusion 400 can be clamped and matched with the clamping groove 220.

[0064] It should be noted that the number of the clamping protrusions 400 is multiple, and the multiple clamping protrusions 400 have a spacing in the circumferential direction of the sleeve 500. For example, in this embodiment, the number of the clamping protrusions 400 is two.

[0065] In this embodiment, optionally, the number of the clamping grooves 220 on the outer peripheral surface of the second plug-in member 200 is multiple. For example, the number of the clamping grooves 220 is two.

[0066] Furthermore, a second guiding inclined surface 230 is provided on the outer peripheral surface of the second plug-in member 200, and one side of the second guiding inclined surface 230 is connected to the groove wall of the clamping groove 220.

[0067] Optionally, the elastic reset member can be but is not limited to a spring.

[0068] Please refer to Figures 8-10, Optionally, the charge and discharge waterproof connector further includes a first magnet 600 and a second magnet 700. The first magnet 600 is connected to the first plug-in member 100, and the second magnet 700 is connected to the second plug-in member 200. When the first plug-in member 100 is plugged and matched with the second plug-in member 200, the first magnet 600 and the second magnet 700 are magnetically adsorbed. It should be noted that when the first plug-in member 100 and the second plug-in member 200 are aligned, the poles of the first magnet 600 and the second magnet 700 are different and can attract each other. When the first plug-in member 100 and the second plug-in member 200 are plugged without alignment, the poles of the first magnet 600 and the second magnet 700 are the same and repel each other, playing an anti-misinsertion role. At the same time, after the first plug-in member 100 and the second plug-in member 200 are plugged and matched, the first plug-in member 100 and the second plug-in member 200 are connected not only by the plugging structure of the plug and the socket itself and the clamping structure of the limiting protrusion 510 and the clamping groove 220, but also by the magnetic adsorption connection of the first magnet 600 and the second magnet 700, making the connection structure of the first plug-in member 100 and the second plug-in member 200 more firm and reliable, enabling the transmission of current and signals to be more stable, that is, the current and signals can be stably transmitted to the device or product through the connector; due to the good stability of the magnet, it can adapt to high-temperature or low-temperature environments, that is, in high-temperature or low-temperature environments, the magnet also has good adsorption ability, thus making the connection between the first plug-in member 100 and the second plug-in member 200 more firm. Moreover, due to the cooperation of multiple anti-disconnection structures, even under the jitter working condition of the device or product, the first plug-in member 100 and the second plug-in member 200 are not easy to loosen and fall off, and it is not easy to affect the transmission of current and signals, and the use is safe and reliable.

[0069] In the charging and discharging waterproof connector provided in this embodiment, when the sleeve 500 and the first plug-in connector 100 are assembled, the sleeve 500 abuts against the middle limiter, which is the first working position of the sleeve 500. When the first connector 100 and the second connector 200 are close to each other for plugging, the first guide bevel 410 on the locking protrusion 400 contacts the second guide bevel 230 on the second connector 200. Under the joint guidance of the first guide bevel 410 and the second guide bevel 230, the locking protrusion 400 first rotates along the second preset direction to stretch the elastic reset member. When the locking protrusion 400 passes over the second guide bevel 230 and enters the locking groove 220, the locking protrusion 400 is pulled into the locking groove 220 under the elastic force of the elastic reset member, thereby realizing the locking fit between the locking protrusion 400 and the locking groove 220, realizing the axial limitation of the sleeve 500 and the second connector 200 on the second connector 200, and the sleeve 500 will not be separated from the second connector 200, that is, the first connector 100 will not be separated from the second connector 200, thereby improving the firmness of the connection. When it is necessary to pull out the first connector 100, first rotate the sleeve 500 along the second preset direction so that the sleeve 500 abuts against the second limiting protrusion 510. This is the second working position of the sleeve 500, and when the sleeve 500 rotates, it can drive the locking protrusion 400 to rotate along the second preset direction and disengage from the locking groove 220. At this time, the first connector 100 and the second connector 200 can be separated.

[0070] It should be noted that the intermediate blocking member 150 may not be provided, and the position of the first blocking member 140 may be adjusted so that the sleeve 500 can pass through the inlet and outlet 130 when rotating in both the first preset direction and the second preset direction, thereby allowing the sleeve 500 to be removed, thereby achieving a detachable connection between the sleeve 500 and the first connector 100.

[0071] In addition, the sleeve 500 and the first connector 100 may be detachably connected by adopting a threaded structure or other snap-fit structures.

[0072] It should be noted that an arrow mark may be provided on the outside of the sleeve 500 to prompt the operator to rotate the sleeve 500 in the direction of arrow 001 to disengage the engaging protrusion 400 from the engaging groove 220. Furthermore, to ensure that the sleeve 500 is in the same working position when assembling the first connector 100 and the second connector 200, the operator may first rotate the sleeve 500 in the direction opposite to arrow 001 until the sleeve 500 abuts against the intermediate stopper 150 and cannot rotate further. It should be understood that arrow 001 is the second predetermined direction, and the direction opposite to the arrow is the first predetermined direction.

[0073] It should be noted that in order to improve the waterproof performance of the charging and discharging waterproof connector, a sealing ring is provided on the inner wall of the sleeve 500. When the second plug-in member 200 is inserted into the sleeve 500, the end of the second plug-in member 200 abuts against the sealing ring, thereby improving the sealing performance.

[0074] In this embodiment, the waterproof connector further includes a power cord 800. The first plug-in member 100 is connected to the power cord 800, and the power cord 800 is used for electrical connection with a power source.
