Description

Technical Field

[0001] The present invention belongs to the technical field of power connectors, and in particular relates to a connector and a driving device. Background Art

[0002] A connector, also known as a plug connector, includes a plug and a socket. The plug is plugged into the socket so that two products can be electrically connected or communicated through the connector. In order to achieve the connection between the plug and the socket, the plug and the socket are generally connected through a hard connection, that is, the plug and the socket have an interference fit.

[0003] However, a large friction force is generated when the plug is inserted into the socket, causing severe wear of the hard connection, resulting in a shorter service life of the connector. In addition, the connector is more likely to loosen when accidentally pulled or vibrated, resulting in poor connection reliability of the connector.

[0004] Therefore, there is an urgent need for connectors with longer life and higher connection reliability. Summary of the invention

[0005] In order to solve the deficiencies of the prior art, the present invention provides a connector and a driving device. Since the inner wall of the locking groove hinders the elastic clamping part from moving into the guide groove, pulling and vibration will not be able to drive the elastic clamping part to move into the guide groove, thereby improving the locking stability of the locking sleeve and further improving the connection reliability of the connector. The plug and the socket are plugged in through a soft connection, which delays the wear of the connector and extends the service life of the connector.

[0006] The technical effects to be achieved by the present invention are achieved through the following aspects:

[0007] In a first aspect, the present invention provides a connector, comprising:

[0008] A plug, wherein a limiting portion is protruded from the outer side of the plug;

[0009] A socket, wherein a connection groove is formed on one end surface of the socket, one end of the plug is inserted into the connection groove, a guide groove is formed on the outer side of the socket, the guide groove is extended along the circumferential direction and the axial direction of the socket, a first end of the guide groove extends to the end surface of the socket on which the connection groove is formed, and a locking groove connected to the second end of the guide groove is further formed on the outer side of the socket, the locking groove is recessed on a side of the guide groove adjacent to the plug; and

[0010] A locking sleeve is sleeved on the plug and has an interference fit with the plug, the locking sleeve is provided with a limiting groove, the limiting groove is extended along the circumferential direction of the locking sleeve, the limiting part is movably arranged in the limiting groove, so that the locking sleeve can rotate along the circumferential direction of the plug; the locking sleeve is also sleeved on the socket, and an elastic clamping part is convexly provided on the inner wall of the locking sleeve. When the plug is inserted into the connecting groove, the locking sleeve rotates along the circumferential direction of the plug, and at the same time, the elastic clamping part slides into the locking groove along the guide groove, so that the elastic clamping part is clamped in the locking groove.

[0011] In some preferred embodiments, a switching transition portion is convexly provided on the inner wall of the limiting groove to divide the limiting groove into a connected unlocking area and a locking area, and the unlocking area and the locking area are arranged in the circumferential direction of the locking sleeve;

[0012] When the elastic clamping portion is located at the first end of the guide groove, the limiting portion is located in the unlocking area; when the elastic clamping portion is located in the locking groove, the limiting portion is located in the locking area.

[0013] In this implementation, before the plug is inserted into the plugging slot, the limiting portion is located in the unlocking zone, so that the elastic clamping portion can be aligned with the first end of the guide slot when plugged in, that is, the elastic clamping portion can be aligned with the entrance of the guide slot, so that the elastic clamping portion is aligned with the entrance of the guide slot 202 when plugged in, thereby improving the assembly efficiency of the connector. When the elastic clamping portion is located in the locking slot, the limiting portion is located in the locking zone, so that the limiting portion is limited in the locking zone, thereby improving the locking stability of the locking sleeve and further improving the connection reliability of the connector.

[0014] In some preferred embodiments, a locking guide slope is provided on a side of the switching transition portion adjacent to the unlocking zone.

[0015] In some preferred embodiments, an unlocking guide slope is provided on a side of the switching transition portion adjacent to the locking area.

[0016] In some preferred embodiments, the locking sleeve is further provided with a deformation auxiliary groove, the deformation auxiliary groove is extended along the circumference of the locking sleeve, the deformation auxiliary groove is communicated with the limiting groove, and a blocking portion is formed between the deformation auxiliary groove and the limiting groove.

[0017] In some preferred embodiments, a guiding slope is provided on a side of the blocking portion facing away from the limiting groove.

[0018] In some preferred embodiments, a plurality of anti-slip ribs are convexly provided on the outer side of the locking sleeve, and the plurality of anti-slip ribs are arranged at intervals along the circumference of the locking sleeve.

[0019] In some preferred embodiments, the extending direction of the anti-slip rib is parallel to the axial direction of the locking sleeve.

[0020] In some preferred embodiments, two opposite sides of the anti-slip rib are respectively provided with anti-slip arc surfaces, and the anti-slip arc surfaces are recessed toward the inside of the anti-slip rib.

[0021] In a second aspect, the present invention provides a driving device, comprising the above-mentioned connector.

[0022] In summary, the present invention has at least the following benefits:

[0023] 1. In the connector provided by the present invention, since the locking sleeve and the plug are interference-fitted, the locking sleeve has a damping effect, so that the locking sleeve can rotate only under the action of a rotational force; and since the locking groove is connected to the end of the guide groove away from the plug, and the locking groove is recessed on the side of the guide groove adjacent to the plug, the inner wall of the locking groove hinders the elastic clamping part from moving into the guide groove; when the elastic clamping part is clamped in the locking groove, since the inner wall of the locking groove hinders the elastic clamping part from moving into the guide groove, pulling and vibration will not be able to drive the elastic clamping part to move into the guide groove, that is, pulling and vibration cannot drive the locking sleeve to rotate in the unlocking direction, thereby improving the locking stability of the locking sleeve and further improving the connection reliability of the connector.

[0024] 2. The connector provided by the present invention has an elastic snap-fitting portion which is an elastic structure, so that the connection structure between the locking sleeve and the socket is a soft connection, that is, the plug and the socket are plugged in through a soft connection, avoiding the use of a hard connection to achieve the plug-in connection between the plug and the socket, delaying the wear of the connector and extending the service life of the connector.

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of them.

[0043] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. 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.

[0044] Embodiment 1:

[0045] Please refer to the attached Figures 1 to 7 The connector 10 of the embodiment of the present invention includes a plug 100 , a socket 200 and a locking sleeve 300 .

[0046] The outer side of the plug 100 is provided with a stopper 110, one end surface of the socket 200 is provided with a connection groove 201, one end of the plug 100 is inserted into the connection groove 201, and the outer side of the socket 200 is provided with a guide groove 202, which is extended along the circumferential direction and axial direction of the socket 200, and the extension direction of the guide groove 202 is arc-shaped, and the first end of the guide groove 202 extends to the end surface of the socket 200 provided with the connection groove 201, so that the first end of the guide groove 202 is an entrance. The outer side of the socket 200 is also provided with a locking groove 203 connected to the second end of the guide groove 202, and the locking groove 203 is recessed on the side of the guide groove 202 adjacent to the plug 100. The locking sleeve 300 is sleeved on the plug 100 and is interference fit with the plug 100. The locking sleeve 300 is provided with a limiting groove 301, and the limiting groove 301 is extended along the circumference of the locking sleeve 300. The limiting portion 110 is movably arranged in the limiting groove 301, that is, the limiting portion 110 is located in the limiting groove 301 and is movably connected to the locking sleeve 300, so that the locking sleeve 300 can rotate along the circumference of the plug 100. The locking sleeve 300 has two opposite rotation directions, one of which is a locking direction, and the other is an unlocking direction.

[0047] The locking sleeve 300 is preferably, but not limited to, an integrally formed structure. The locking sleeve 300 is also sleeved on the socket 200. The inner wall of the locking sleeve 300 is convexly provided with an elastic clamping portion 310. The elastic clamping portion 310 is made of an elastic material, preferably, but not limited to, plastic. When the plug 100 is inserted into the connecting groove 201, the locking sleeve 300 is rotated in the locking direction, that is, the locking sleeve 300 is rotated in the direction of arrow a, so that the locking sleeve 300 rotates along the circumference of the plug 100. At the same time, the elastic clamping portion 310 slides from the first end of the guide groove 202 into the guide groove 202, and then slides into the locking groove 203 along the guide groove 202, so that the elastic clamping portion 310 is clamped in the locking groove 203. When the plug 100 is pulled out of the connecting slot 201, the locking sleeve 300 is rotated in the unlocking direction, that is, the locking sleeve 300 is rotated in the direction of arrow b, so that the elastic clamping portion 310 is disengaged from the locking slot 203, and at the same time, the elastic clamping portion 310 slides from the second end of the guide slot 202 to the first end of the guide slot 202, and then completely slides out of the guide slot 202, so that the elastic clamping portion 310 is completely separated from the socket 200.

[0048] It should be emphasized that during the process of plugging and unplugging the plug 100 , the locking sleeve 300 rotates synchronously.

[0049] The connector 10 provided by the present invention has a damping effect due to the interference fit between the locking sleeve 300 and the plug 100, so that the locking sleeve 300 has a damping effect, so that the locking sleeve 300 can rotate only under the action of a rotating force; and because the locking groove 203 is connected to the end of the guide groove 202 away from the plug 100, and the locking groove 203 is recessed on the side of the guide groove 202 adjacent to the plug 100, the inner wall of the locking groove 203 hinders the elastic clamping portion 310 from moving into the guide groove 202; when the elastic clamping portion 310 is clamped in the locking groove 203, since the inner wall of the locking groove 203 hinders the elastic clamping portion 310 from moving into the guide groove 202, pulling or vibration will not be able to drive the elastic clamping portion 310 to move into the guide groove 202, that is, pulling or vibration cannot drive the locking sleeve 300 to rotate in the unlocking direction, thereby improving the locking stability of the locking sleeve 300 and further improving the connection reliability of the connector 10.

[0050] Furthermore, since the elastic snap-fit ​​portion 310 is an elastic structure, the connection structure between the locking sleeve 300 and the socket 200 is a soft connection, that is, the plug 100 and the socket 200 are plugged in through a soft connection, avoiding the use of a hard connection to achieve the plugging of the plug 100 and the socket 200, delaying the wear of the connector 10 and extending the service life of the connector 10.

[0051] In some preferred embodiments, the inner wall of the limiting groove 301 is provided with a switching transition portion 320 to divide the limiting groove 301 into a connected unlocking area 3011 and a locking area 3012, and the unlocking area 3011 and the locking area 3012 are arranged in the circumferential direction of the locking sleeve 300. When the locking sleeve 300 rotates, the limiting portion 110 switches between the unlocking area 3011 and the locking area 3012. In this embodiment, before the plug 100 is inserted into the connecting groove 201, the limiting portion 110 is located in the unlocking area 3011, so that the elastic clamping portion 310 can be aligned with the first end of the guide groove 202 during insertion, that is, the elastic clamping portion 310 can be aligned with the entrance of the guide groove 202, so that the elastic clamping portion 310 is aligned with the entrance of the guide groove 202 during insertion, thereby improving the assembly efficiency of the connector 10. When the elastic clamping portion 310 is located in the locking groove 203 , the limiting portion 110 is located in the locking area 3012 , so that the limiting portion 110 is limited in the locking area 3012 , thereby improving the locking stability of the locking sleeve 300 and further improving the connection reliability of the connector 10 .

[0052] In some preferred embodiments, a locking guide inclined surface 321 is provided on one side of the switching transition portion 320 adjacent to the unlocking area 3011. In this embodiment, when the locking sleeve 300 rotates in the locking direction, the limiting portion 110 switches from the unlocking area 3011 to the locking area 3012. During the switching process of the limiting portion 110, the limiting portion 110 is slidably connected with the locking guide inclined surface 321, which is conducive to the limiting portion 110 expanding the limiting groove 301 so that the limiting portion 110 enters the locking area 3012 through the switching transition portion 320, thereby reducing the difficulty of the locking sleeve 300 rotating in the locking direction and improving the smoothness of locking.

[0053] In some preferred embodiments, an unlocking guide inclined surface 322 is provided on one side of the switching transition portion 320 adjacent to the locking area 3012. In this embodiment, when the locking sleeve 300 rotates in the unlocking direction, the limiting portion 110 switches from the locking area 3012 to the unlocking area 3011. During the switching process of the limiting portion 110, the limiting portion 110 is slidably connected with the unlocking guide inclined surface 322, which is conducive to the limiting portion 110 expanding the limiting groove 301, so that the limiting portion 110 enters the unlocking area 3011 through the switching transition portion 320, reducing the difficulty of the locking sleeve 300 rotating in the unlocking direction and improving the smoothness of unlocking.

[0054] In some preferred embodiments, the locking sleeve 300 is further provided with a deformation auxiliary groove 302, which is extended along the circumference of the locking sleeve 300, and is connected to the limiting groove 301. A blocking portion 330 is formed between the deformation auxiliary groove 302 and the limiting groove 301, and the blocking portion 330 is used to block the limiting portion 110 from moving from the unlocking area 3011 to the deformation auxiliary groove 302. In this embodiment, the deformation auxiliary groove 302 increases the deformation space of the locking sleeve 300, which is conducive to the elastic deformation of the locking sleeve 300, and further facilitates the switching of the limiting portion 110 between the unlocking area 3011 and the locking area 3012, that is, it is conducive to reducing the force of rotating the locking sleeve 300, reducing the difficulty of rotating the locking sleeve 300, and the locking sleeve 300 can be rotated without the aid of tools, thereby improving the convenience of rotating the locking sleeve 300.

[0055] In some preferred embodiments, a guide slope 331 is provided on the side of the blocking portion 330 away from the limiting groove 301. In this embodiment, when the locking sleeve 300 is put on the plug 100, if the limiting portion 110 is accidentally set in the deformation auxiliary groove 302, the locking sleeve 300 is rotated to move the limiting portion 110 to the unlocking area 3011. During the movement of the limiting portion 110 to the unlocking area 3011, the limiting portion 110 is slidably connected with the guide slope 331 and expands the connection between the deformation auxiliary groove 302 and the unlocking area 3011, so that the limiting portion 110 can enter the unlocking area 3011 from the deformation auxiliary groove 302, that is, the limiting portion 110 can be set in the unlocking area 3011 by rotating the locking sleeve 300, thereby avoiding the problem that the auxiliary limiting groove 301 causes the locking sleeve 300 to be unable to be used normally.

[0056] In some preferred embodiments, a plurality of anti-skid ribs 340 are convexly provided on the outer side of the locking sleeve 300, and the plurality of anti-skid ribs 340 are arranged at intervals along the circumference of the locking sleeve 300. When the operator rotates the locking sleeve 300, the anti-skid ribs 340 come into contact with the anti-skid ribs 340, thereby increasing the friction of the locking sleeve 300 and suppressing the problem of slipping when the locking sleeve 300 is rotated.

[0057] In some preferred embodiments, the extension direction of the anti-slip rib 340 is parallel to the axial direction of the locking sleeve 300 , so that the anti-slip rib 340 is perpendicular to the rotation direction, thereby improving the anti-slip effect of the anti-slip rib 340 .

[0058] In some preferred embodiments, anti-slip arc surfaces 341 are respectively provided on the opposite sides of the anti-slip rib 340, and the anti-slip arc surfaces 341 are recessed toward the inside of the anti-slip rib 340, thereby increasing the surface area of ​​the anti-slip rib 340 and helping to improve the anti-slip effect of the anti-slip rib 340.

[0059] In some preferred embodiments, the limiting portion 110 is provided with an installation bevel 111. When the locking sleeve 300 is installed on the plug 100, the locking sleeve 300 is slidably connected to the installation bevel 111, so that the installation bevel 111 guides the installation of the locking sleeve 300, making it easier to install the locking sleeve 300 on the plug 100, thereby improving the smoothness of assembly of the connector 10.

[0060] In some preferred embodiments, the elastic clamping portion 310 is located at the first end of the locking sleeve 300, and a sliding inclined surface 311 is provided on one side of the elastic clamping portion 310 adjacent to the first end surface of the locking sleeve 300. In this embodiment, when the elastic clamping portion 310 slides into the guide groove 202, the sliding inclined surface 311 first abuts against the entrance of the guide groove 202 to guide the elastic clamping portion 310 to gradually deform and enter the guide groove 202, so that the sliding inclined surface 311 guides the elastic clamping portion 310 to slide into the guide groove 202, thereby improving the smoothness of the insertion of the socket 200 into the connecting groove 201, that is, improving the assembly smoothness of the connector 10.

[0061] Furthermore, there are two elastic clamping parts 310 , which are symmetrically arranged inside the locking sleeve 300 , thereby improving the stability of the clamping.

[0062] In some preferred embodiments, there are two limiting parts 110, which are symmetrically arranged on both sides of the plug 100. There are two limiting grooves 301, which are symmetrically arranged on the locking sleeve 300. The two limiting parts 110 are movably arranged in the two limiting grooves 301 and movably connected to the locking sleeve 300. The two symmetrically arranged limiting parts 110 are connected to the locking sleeve 300, which improves the force uniformity of the locking sleeve 300, thereby improving the position stability of the locking sleeve 300, thereby improving the locking stability of the locking sleeve 300, and improving the connection reliability of the connector 10.

[0073] In some preferred embodiments, the plug body 120 is provided with a first snap-fitting portion 120a at the opening of the first mounting groove 121, and a first snap-fitting groove 133 is provided on the outer side of the first terminal fixing member 130. The first snap-fitting portion 120a is located in the first snap-fitting groove 133 and is snap-fitted with the first terminal fixing member 130, that is, the first snap-fitting portion 120a is snap-fitted in the first snap-fitting groove 133, so that the first terminal fixing member 130 is fixed in the first mounting groove 121.

[0074] Furthermore, there are multiple first snap-fitting portions 120a, which are evenly spaced along the circumference of the plug body 120; there are multiple first snap-fitting grooves 133, which are one-to-one snap-fitting portions 120a that are snap-fitted into the multiple first snap-fitting grooves 133, so that the force on the first terminal fixing member 130 is uniform, thereby making the position stability of the first terminal fixing member 130 higher.

[0085] Embodiment 3:

[0086] Based on the above embodiments, this embodiment provides a driving device, including a connector 10 , a battery, and a motor, wherein the battery is electrically connected to the motor through the connector 10 .

[0087] Specifically, the battery is electrically connected to one of the plug 100 and the socket 200, and the motor is electrically connected to the other of the plug 100 and the socket 200. The plug 100 is inserted into the connecting groove 201 of the socket 200, so that the plug 100 is electrically connected to the socket 200, and then the battery is electrically connected to the motor.

[0088] The driving device provided by the present invention has a damping effect due to the interference fit between the locking sleeve 300 and the plug 100, so that the locking sleeve 300 can rotate only under the action of the rotational force; and because the locking groove 203 is connected to the end of the guide groove 202 away from the plug 100, and the locking groove 203 is recessed on the side of the guide groove 202 adjacent to the plug 100, the inner wall of the locking groove 203 hinders the elastic clamping part 310 from moving into the guide groove 202; when the elastic clamping part 310 is clamped in the locking groove 203, since the inner wall of the locking groove 203 hinders the elastic clamping part 310 from moving into the guide groove 202, pulling or vibration will not be able to drive the elastic clamping part 310 to move into the guide groove 202, that is, pulling or vibration cannot drive the locking sleeve 300 to rotate in the unlocking direction, thereby improving the locking stability of the locking sleeve 300 and further improving the connection reliability of the connector 10.

[0089] Furthermore, since the elastic snap-fit ​​portion 310 is an elastic structure, the connection structure between the locking sleeve 300 and the socket 200 is a soft connection, that is, the plug 100 and the socket 200 are plugged in through a soft connection, avoiding the use of a hard connection to achieve the plugging of the plug 100 and the socket 200, delaying the wear of the connector 10 and extending the service life of the connector 10.
