[0002] Electrical connectors consist of a fixed-end connector, or female contact (referred to as a socket), and a free-end connector, or male contact (referred to as a plug). The socket is secured to the electrical component via its square (or round) disc (sometimes welded). The plug is typically connected to the cable, and the connection between the cable and the socket is established through a connecting assembly. Existing electrical connectors can easily twist and deform during installation or removal of cables due to relative movement between the two ends. This can cause the cable to squeeze the internal wiring, causing deformation and disrupting data transmission within the cable, necessitating urgent improvements. Utility Model Content

[0003] The purpose of the utility model is to provide a rotatable connector to solve the technical problem that when the two ends of the existing cable move relative to each other, the cable body is twisted and deformed.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to provide a rotatable connector, including a first connector and a second connector both configured as a cylinder, the first connector and the second connector being coaxial and sealedly connected, the first connector being able to rotate relative to the second connector, and the rotation angle of the first connector being less than 360°.

[0005] In one possible implementation, one end of the first connector can be connected to the connecting pipe, and the other end is sealed and connected to the second connector. The second connector is configured as a sleeve shaft, and the sleeve shaft includes a shaft neck and a shaft body that are integrally connected. The outer diameter of the shaft neck is larger than the outer diameter of the shaft body. A limiting protrusion is provided on the end face of the shaft neck facing the first connector. An arc groove is formed in the first connector, and the center of the long axis of the arc groove is collinear with the axis of the first connector. The limiting protrusion is slidably adapted to the arc groove.

[0006] In one possible implementation, the rotatable connector also includes a sealing assembly, which includes a sleeve coaxially sleeved on the outer periphery of the shaft neck, and one end of the sleeve is provided with a trim extending toward the axis of the sleeve, and the other end is threadedly adapted to the first connector, the trim abuts against the end face of the shaft neck facing away from the first connector, the sleeve can rotate relative to the shaft neck, and the inner wall of the sleeve is sealed against the outer periphery of the shaft neck.

[0007] In one possible implementation, the sealing assembly further includes a sealing ring disposed between the sleeve and the shaft neck, the outer periphery of the shaft neck is provided with a mounting groove coaxial with the first connector, the sealing ring is sleeved in the mounting groove, and the sealing ring can form a seal between the shaft neck and the sleeve.

[0008] In a possible implementation, the sealing ring is made of self-lubricating rubber.

[0009] In a possible implementation, the limiting protrusion is elastically and telescopically connected to the journal.

[0010] In one possible implementation, a first mounting hole is provided on the end surface of the shaft neck facing the first connecting head, a support spring is provided in the first mounting hole, the limiting protrusion is inserted into the first mounting hole, the two ends of the support spring are respectively connected to the limiting protrusion and the bottom of the first mounting hole, and the support spring and the first mounting hole both extend along the axial direction of the shaft neck.

[0012] Compared with the prior art, the rotatable connector provided by the present invention has the following advantages:

[0013] First, when relative twisting or relative rotation occurs at the two ends of the cable, torsional stress will exist in the cable. In the present invention, the above stress can be released by rotating the first connector relative to the second connector, so that the outer periphery of the cable remains smooth, solving the technical problem of the existing cable affecting the internal data transmission due to the relative displacement of the two ends; at the same time, in the present invention, the rotation angle of the first connector is less than 360°, so as to limit the rotation angle of the first connector and prevent the internal circuit from being damaged due to the unlimited rotation of the first connector.

[0014] Secondly, the present invention can limit the rotation angle of the first connector by the sliding fit between the limiting protrusion and the arc-shaped groove, so as to prevent the connector from rotating at an excessively large angle and causing damage to the internal circuit.

[0015] In addition, the present invention can also form a seal and rotational fit between the first connector and the second connector through the sleeve in the sealing assembly, thereby preventing the first connector and the second connector from loosening along the axial direction and making the connection between the two connectors more stable.

[0016] In addition to the above beneficial effects, the present invention can also prevent the elastic protrusion from pressing against the bottom of the first connector during installation by elastically extending and contracting the limiting protrusion, thereby making the connection between the first connector and the second connector more convenient.

[0017] Another object of the present invention is to provide an electrical device comprising the rotatable connector mentioned above.

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Please also refer to Figures 1 to 5 , the rotatable connector provided by the present invention is now described. The rotatable connector includes a first connector 1 and a second connector 2, both of which are configured as cylindrical bodies. The first connector 1 and the second connector 2 are coaxial and sealed, and the first connector 1 can rotate relative to the second connector 2. The rotation angle of the first connector 1 is less than 360°. The torsional stress existing in the cable is released by the relative rotation of the two connectors, so that the cable maintains a smooth transition on the periphery during the torsion process, thereby solving the technical problem that the existing cable is twisted and deformed due to the relative displacement of the two ends, thereby affecting the internal data transmission. At the same time, this embodiment can prevent the first connector 1 from excessive rotation by limiting the rotation angle of the first connector 1, which can not only facilitate the removal of the entire connector, but also prevent the circuit in the first connector 1 from being damaged due to unlimited rotation, thereby helping to improve the stability of the connection and the convenience of disassembly and assembly of the rotatable connector in the present invention.

[0034] In some feasible embodiments, one end of the first connector 1 can be connected to the connecting pipe, and the other end is sealed and connected to the second connector 2. The second connector 2 is configured as a sleeve shaft, which includes a shaft neck 21 and a shaft body 22 connected as one piece. The outer diameter of the shaft neck 21 is larger than the outer diameter of the shaft body 22. The end face of the shaft neck 21 facing the first connector 1 is provided with a limiting protrusion 211. An arc groove 11 is formed in the first connector 1. The center of the long axis of the arc groove 11 is collinear with the axis of the first connector 1. The limiting protrusion 211 is slidably adapted to the arc groove 11. Therefore, this embodiment can limit the rotation angle of the first connector 1 by sliding adaptation between the arc groove 11 and the limiting protrusion 211, thereby preventing the first connector 1 from rotating arbitrarily relative to the second connector 2, thereby helping to prevent damage to the circuit in the rotatable connector in this embodiment.

[0035] In some feasible embodiments, the rotatable connector also includes a sealing assembly 3, which includes a sleeve 31 coaxially sleeved on the outer periphery of the shaft neck 21, and one end of the sleeve 31 is provided with a closing edge 311 extending toward the axis of the sleeve 31, and the other end is threadedly adapted to the first connector 1, and the closing edge 311 abuts against the end face of the shaft neck 21 facing away from the first connector 1, and the sleeve 31 can rotate relative to the shaft neck 21, and the inner wall of the sleeve 31 seals and abuts against the outer periphery of the shaft neck 21. As set above, this embodiment can form an axial locking for the first connector 1 and the second connector 2 by abutting the closing edge 311 of the sleeve 31 with the end face of the first connector 1, and prevent external dust from entering the interior of the connector in the utility model by sealing the inner wall of the sleeve 31 with the outer periphery of the shaft neck 21, so that the two connectors can rotate relative to each other while the interior of the connector of this embodiment can also be kept clean. Optionally, after the port of the sleeve 31 is threadedly adapted to the first connector 1, the peripheries of the two are connected by laser welding to make the connection between the sleeve 31 and the first connector 1 more secure and improve the sealing strength between the first connector 1 and the sleeve.

[0036] Based on the above embodiments, further, in some embodiments, the sealing assembly 3 also includes a sealing ring 32 arranged between the sleeve 31 and the shaft neck 21, and the outer periphery of the shaft neck 21 is provided with a mounting groove 213 coaxial with the first connector 1, and the sealing ring 32 is sleeved in the mounting groove 213. The sealing ring 32 can form a seal between the shaft neck 21 and the sleeve 31 to prevent external foreign matter from invading the interior of the connector. Preferably, the sealing ring 32 is made of self-lubricating rubber to make the relative rotation of the first connector 1 and the second connector 2 smoother and improve the sealing effect between the shaft neck 21 and the sleeve 31.

[0037] In some feasible embodiments, the limiting protrusion 211 can be elastically and retractably connected to the shaft neck 21 to prevent the bottom of the first connector 1 from colliding with the limiting protrusion 211 of the second connector 2 as the first connector 1 gradually approaches the second connector 2, thereby making the assembly process of the rotatable connector in this embodiment more scientific and reasonable.

[0038] Based on the above embodiment, in a more preferred embodiment, a first mounting hole 212 is opened on the end face of the shaft neck 21 facing the first connecting head 1, and a support spring 23 is provided in the first mounting hole 212, and a limiting protrusion 211 is inserted into the first mounting hole 212, and the two ends of the support spring 23 are respectively connected to the limiting protrusion 211 and the bottom of the first mounting hole 212, and the support spring 23 and the first mounting hole 212 both extend along the axial direction of the shaft neck 21 to form an elastic support for the limiting protrusion 211 through the spring, and the limiting protrusion 211 can retract axially when subjected to axial pressure to prevent the limiting protrusion 211 from scratching the bottom surface of the first connecting head 1. Optionally, a smooth transition curved surface is provided at the end of the limiting protrusion 211 facing the first connecting head 1 to make the sliding of the limiting protrusion 211 smoother to prevent the sharp part of the limiting protrusion 211 from scratching the bottom surface of the first connecting head 1.

[0039] In some feasible embodiments, a second mounting hole 2110 is provided at one end of the limiting protrusion 211 located in the first mounting hole 212, one end of the support spring 23 is connected to the bottom of the first mounting hole 212, and the other end is connected to the bottom of the second mounting hole 2110, so that the two mounting holes can form a accommodating space for the support spring 23, making the connection between the support spring 23 and the limiting protrusion 211 and the second connector 2 more reasonable.

[0040] In summary, when the rotatable connector in the present invention is relatively twisted or rotated at both ends of the cable, the present invention can release the torsional stress of the cable by rotating the first connector 1 relative to the second connector 2, so that the outer periphery of the cable remains smooth, solving the technical problem of the existing cable affecting the internal data transmission due to the relative displacement of the two ends; at the same time, the present invention can limit the rotation angle of the first connector 1 by sliding the limiting protrusion 211 and the arc groove 11 to prevent the rotation angle of the connector from being too large and causing damage to the internal circuit. Furthermore, the present invention can also form a seal and rotational adaptation between the first connector 1 and the second connector 2 through the sleeve 31 in the sealing assembly 3, preventing the first connector 1 and the second connector 2 from loosening along the axial direction, making the connection between the two connectors more stable.

[0041] In addition to the above beneficial effects, the present invention can also prevent the elastic protrusion from pressing against the bottom of the first connector 1 during installation through the elastic expansion and contraction of the limiting protrusion 211, making the connection between the first connector 1 and the second connector 2 more convenient.

[0042] Based on the same inventive concept, the present invention also provides an electrical device, which includes the rotatable connector mentioned above.

[0043] Compared with the existing technology, the electrical equipment in the present invention, by setting the rotatable connector mentioned above, can make the connection state of the cables in the electrical equipment more stable when adjusting the relative position of the specific structure in the electrical equipment, and maintain stable signal transmission, which is conducive to solving the technical problem of cable distortion caused by position adjustment of the existing electrical equipment.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
