Description

Technical Field

[0001] The present application relates to the field of electrical connections, in particular to a socket for a rotary connector and the rotary connector thereof. Background Art

[0002] In some application scenarios, in order to simultaneously achieve reliable transmission of multiple signals and to adapt to the situation where the plug and the socket can be rotated and inserted at a certain angle, the docking part of the plug and the socket is designed to be convenient for screwing and inserting, and at the same time, in order not to affect the reliable transmission of signals.

[0003] Existing electrical rotary connectors are connectors that can transmit electrical signals in a rotating state. The existing rotatable electrical connectors introduced in patents such as Patent CN201975659U with the name "Electrical Rotary Connector for Preventing Wire Jumping and Short Circuit", Patent CN106099505A with the name "Rotary Electrical Connector Assembly and Its Rotary Electrical Connector", Patent CN106099505B with the name "Rotary Electrical Connector Assembly and Its Rotary Electrical Connector", and Patent CN105428951A with the name "An Electrical Rotary Connector" all use two important components, namely an electrical slip ring and a brush, as the core components for electrical signal transmission. The electrical slip ring is in a rotating state, and the brush is in a fixed state. The brush is in sliding electrical connection with the electrical slip ring to achieve electrical circuit conduction. Generally, the brush is formed by a wiring piece component. One end of the wiring piece component has two working segments separated in a V shape. The two working segments are formed by contact wire springs, and the other end of the wiring piece is a wiring terminal. The rotatable electrical connectors involved in the above patents adopt an integrated structure, generally provided with multiple bearings, with large structural dimensions, heavy weight, and the phenomenon of wire jumping is likely to occur in the brush. The rotatable connectors of the above patents have great limitations in the field of deep drilling. Summary of the Invention

[0004] In order to overcome the deficiencies in the prior art that the rotary connector cannot be made into a split type and is prone to wire jumping during rotation, the present application provides a socket for a rotary connector and the rotary connector thereof, achieving a split structure of the rotary connector and the effect of stable rotation during operation.

[0005] To achieve the above object, the present application adopts the following technical solution: A socket for a rotary connector, the socket includes a connection groove extending axially, and a plurality of electrical connection rings are fixed in the connection groove, which are arranged at intervals along the axial direction around the side wall of the connection groove. At least part of the electrical connection rings protrude from the side wall of the connection groove and are prone to deformation, and each electrical connection ring is electrically connected to a corresponding first wire.

[0006] After adopting the above technical solution, the present application has the following advantages: By providing a connection groove and an electrical connection ring inside the connection groove, the plug inserted can achieve all-round electrical connection with the socket. Moreover, due to the easily deformable characteristic of the electrical connection ring, the electrical connection ring of the socket can always be in contact with the contacts on the plug, ensuring that when the plug and the socket rotate relative to each other, the electrical signal can still be uninterrupted. Therefore, a split structure can be realized. Such a structural design is different from the traditional integrated rotatable electrical connector that uses an electrical slip ring and a carbon brush as the core components, and has a more efficient electrical connection method, so that the stability of the electrical connection will not be damaged due to the insertion and removal of the plug and the socket. And using the electrical connection ring to replace the traditional carbon brush makes the structure more stable.

[0007] Further, the socket further includes a groove body, in which a collecting block, A conductive rings and insulating members provided between two conductive rings are arranged. The connection groove is composed of the inner wall of the conductive ring and the inner wall of the insulating member. The electrical connection ring is fixed on the inner wall of the conductive ring. The first wire forms an electrical connection with the electrical connection ring through the conductive ring. The collecting block is axially provided with a collecting cavity facing away from the conductive ring. The side wall of the collecting cavity is annularly provided with at least A through holes penetrating the collecting block. One end of the first wire is electrically connected to the conductive ring, and the other end passes through the through hole and passes through the collecting cavity.

[0008] Adopting the foregoing technical solution, the interior of the socket is disassembled into multiple modules such as a groove body, a collecting block, a conductive ring, and an insulating member, and the functions of each module are clear. During installation, the construction personnel first install the electrical connection ring on the conductive ring, then connect the first wire to the corresponding conductive ring, and then use a cylindrical tooling to sleeved the conductive ring and the insulating member in turn, so that the first wires on the conductive ring can be gathered together. Subsequently, the first wire is passed through the corresponding through hole and tightened, so that the conductive ring and the insulating ring are in close contact. Then these three types of parts are installed in the groove body. Since the through holes are annularly arranged on the collecting block, the first wires on the conductive ring will be annularly arranged outside each conductive ring along the arrangement of the through holes. This modular assembly method greatly reduces the installation difficulty and the probability of errors compared with the traditional connector with an integral molding and complex structure.

[0009] Further, a boss is provided on the outer side wall of the conductive ring, and a conductive hole for electrically connecting the first wire is provided inside the boss.

[0010] With the foregoing technical solution, by providing a boss on the outer sidewall of the conductive ring, the first wire is directly electrically connected to the conductive hole on the boss, which facilitates the electrical connection method. Compared with directly using welding or other methods for electrical connection on the sidewall, welding within specifically provided holes is more stable and convenient. Moreover, due to the provision of the boss, a space for the first wire to pass through can be created between the electrical connection ring and the groove body, making subsequent installation smoother. In addition, the cooperation between the boss and the groove body causes less damage to the first wire compared to directly welding on the sidewall of the conductive ring without a boss, avoiding pressing the first wire and being more conducive to the installation of the socket.

[0011] Further, a ring groove is provided on the inner wall of the conductive ring, and the electrical connection ring is disposed in the ring groove.

[0012] With the foregoing technical solution, the ring groove can position and limit the electrical connection ring, enabling the electrical connection ring to be stably located at the set position, avoiding unnecessary displacement during use (especially during operations such as plug insertion and removal, relative rotation, etc.), thereby ensuring the stability and reliability of the electrical connection and ensuring that it can always make good contact with the plug to achieve electrical signal transmission.

[0013] Further, the first wire in the collecting cavity is fixed to the collecting block by glue sealing.

[0014] With the foregoing technical solution, glue sealing fixation can enhance the stability of the first wire in the collecting cavity, preventing it from loosening, shifting, or even detaching from its original connection position due to external forces (such as external forces generated by vibration, plugging and unplugging, etc. during the operation of the rotary connector), ensuring the integrity of the entire electrical connection circuit and the continuous stability of electrical signal transmission. The glue sealing can play a certain insulating role, avoiding electrical faults such as short circuits due to accidental contact between different wires, further improving the electrical safety during the use of the rotary connector and enabling it to work reliably under relatively complex working conditions.

[0015] Further, a detachable end cover is provided at the opening of the groove body, and one end of the end cover abuts against the conductive ring.

[0016] With the foregoing technical solution, firstly, the detachable design facilitates operations such as installation, debugging, maintenance, and repair of the components in the groove body. When it is necessary to check or replace components such as the conductive ring, electrical connection ring, and first wire, the end cover can be easily disassembled, with convenient operation, which helps to improve the usability and maintainability of the entire rotary connector. Secondly, the end cover abuts against the conductive ring, which can play a certain role in fixing and limiting the conductive ring, avoiding axial displacement of the conductive ring during use, ensuring its stable position, and further guaranteeing the reliability of the first wire electrically connected to it, ensuring normal electrical signal transmission.

[0017] Further, a retaining ring for holding the electrical connection ring in the connection groove is inserted into the electrical connection ring.

[0018] With the foregoing technical solution, it can play a stabilizing role on the electrical connection ring, preventing the electrical connection ring from accidentally coming out of the connection groove during use, especially when the plug is frequently inserted and removed and rotated relative to the socket, ensuring that it always remains in the correct position, and ensuring that it can maintain good contact with the plug to achieve stable electrical signal transmission. Moreover, the presence of the retaining ring makes the structural integrity of the electrical connection ring stronger, helping to maintain the shape and elastic properties of the electrical connection ring itself, so that it can still better deform to fit the plug and ensure the electrical connection function under external force extrusion, stretching and other conditions, improving the working reliability of the entire rotary connector.

[0019] Further, a part of the first wire passing through the socket is fixed to the socket by a wire fixing adhesive.

[0020] With the foregoing technical solution, first, the stability is enhanced. The wire fixing adhesive can firmly fix the wire, preventing it from shaking or shifting in the socket due to external forces such as vibration and plugging and unplugging actions during the operation of the rotary connector, ensuring that the wire always remains in the correct connection position and ensuring the stability and reliability of the electrical signal transmission line. Second, the safety is improved. It can prevent electrical faults such as short circuits caused by accidental mutual contact and friction between wires, ensuring the electrical safety of the entire rotary connector during use and enabling it to better adapt to different working conditions.

[0021] Further, a fixing ring for connecting to the drilling equipment is provided on the side of the socket away from the plug, and the fixing ring is connected to the socket through an elastic member.

[0022] With the foregoing technical solution, first, by using the buffering effect of the elastic member, when the drilling equipment generates vibrations, impacts, etc. during operation, these external forces can be effectively absorbed, preventing the external forces from being directly transmitted to the socket and the electrical connection components inside it, thereby protecting the stability of the electrical connection structure and preventing problems such as loosening and poor contact of the electrical connection caused by severe vibrations and impacts, ensuring reliable electrical signal transmission. Second, the elastic member connection enables the socket to have the ability of adaptive adjustment within a certain range. When the drilling equipment has slight changes in position or angle due to changes in working conditions, etc., the socket can be adjusted flexibly accordingly, ensuring that the relative position and connection state between it and the plug remain good, and reducing the impact on the electrical connection caused by factors such as relative displacement of the equipment. Third, it is convenient for installation and disassembly. Compared with the rigid connection method, this form of connection through the elastic member is easier to operate when assembling the socket and the fixing ring to the drilling equipment, and it is also easier to disassemble when subsequent maintenance or replacement of the socket or related components is required, improving the convenience of the entire use process.

[0023] A rotary connector includes the above-mentioned socket and also includes a plug. Electric connection rings corresponding to the electric connection circles one by one are sleeved on the plug. Each electric connection ring is electrically connected to a different second wire. When the plug is inserted into the socket, the electric connection circles and the electric connection rings are electrically connected, so that the first wire and the second wire are electrically connected.

[0024] Adopting the foregoing technical solution, this solution abandons the electric slip ring and brush combination that is prone to wire jumping in the traditional integrated structure, and adopts the method of mutual cooperation between the electric connection rings of the plug and the electric connection circles of the socket. Each electric connection ring is electrically connected to a different second wire, corresponding to the corresponding electric connection circles on the socket one by one. The circuit connection is clear, facilitating troubleshooting, maintenance and repair. When a fault occurs, the problem can be quickly located, improving the maintenance efficiency. The plug and the socket are inserted to achieve electrical connection, with simple and efficient operation, convenient for actual plugging and unplugging, meeting the convenience requirements, and reducing the production and assembly costs. During operation, even in complex working conditions such as relative rotation between the plug and the socket and plugging and unplugging at a certain angle, it can ensure continuous and smooth transmission of electrical signals, enhancing the applicability and comprehensive cost performance of the rotary connector in different scenarios.

[0029] The following uses specific embodiments to elaborate in detail on the technical solutions of this application. These several specific embodiments can be combined or replaced according to actual circumstances. For the same or similar concepts or processes, they may not be repeated in some embodiments.

[0030] As Figures 1 to 6 shown, this application provides a socket for a rotary connector. The socket 1 includes a connection groove 11 extending axially. A plurality of electrical connection rings 2 are fixed in the connection groove 11, which are arranged at intervals along the axial direction around the side wall of the connection groove 11. At least part of the electrical connection ring 2 protrudes from the side wall of the connection groove 11 and is prone to deformation. The electrical connection ring 2 is electrically connected to a corresponding first wire 3.

[0031] After adopting the above technical solution, the present application has the following advantages: By providing the connection groove 11 and the electrical connection ring 2 inside the connection groove 11, the plug 10 inserted can achieve all-round electrical connection with the socket 1. Moreover, due to the easily deformable characteristic of the electrical connection ring 2, the electrical connection ring 2 of the socket 1 can always be in contact with the contacts on the plug 10, ensuring that the electrical signal is not interrupted when the plug 10 rotates relative to the socket 1. Therefore, a split structure can be realized. Such a structural design is different from the traditional integrated rotatable electrical connector that uses an electrical slip ring and a carbon brush as the core components, and has a more efficient electrical connection method, so that the stability of the electrical connection will not be damaged due to the insertion and removal of the plug 10 and the socket 1. And using the electrical connection ring 2 to replace the traditional carbon brush makes the structure more stable.

[0032] Preferably, the electrical connection ring 2 is a spring ring. When the plug 10 is inserted, the spring ring can deform towards the side wall, thereby generating a certain pre-pressure, so that the relative rotation of the plug 10 and the socket 1 will not affect the electrical signal transmission between the two.

[0033] Furthermore, the socket 1 further includes a groove body 4. Inside the groove body 4, there are a collecting block 5, A conductive rings 7, and an insulating member 6 provided between two conductive rings 7. The connection groove 11 is composed of the inner wall of the conductive ring 7 and the inner wall of the insulating member 6. The electrical connection ring 2 is fixed on the inner wall of the conductive ring 7. The first wire 3 forms an electrical connection with the electrical connection ring 2 through the conductive ring 7. The collecting block 5 is axially provided with a collecting cavity 52 facing away from the conductive ring 7. The side wall of the collecting cavity 52 is annularly provided with greater than or equal to A through holes 51 penetrating the collecting block 5. One end of the first wire 3 is electrically connected to the conductive ring 7, and the other end passes through the through hole 51 and passes through the collecting cavity 52.

[0034] Adopting the foregoing technical solution, the interior of the socket 1 is disassembled into multiple modules such as the groove body 4, the collecting block 5, the conductive ring 7, and the insulating member 6, and the functions of each module are clear. During installation, the construction personnel first install the electrical connection ring 2 on the conductive ring 7, then connect the first wire 3 to the corresponding conductive ring 7, and then use a cylindrical tooling to sleeved the conductive ring 7 and the insulating member 6 in sequence, so that the first wires 3 on the conductive ring 7 can be collected in one place. Subsequently, the first wire 3 is passed through the corresponding through hole 51 and tightened, so that the conductive ring 7 and the insulating ring are in close contact. Then these three types of parts are installed in the groove body 4. Since the through holes 51 are annularly arranged on the collecting block 5, the first wires 3 on the conductive ring 7 will be annularly arranged outside each conductive ring 7 along the arrangement of the through holes 51. This modular assembly method greatly reduces the installation difficulty and the probability of errors compared with the traditional connector with an integral molding and complex structure.

[0035] Specifically, the first wire 3 has electrical conductivity only at its ends, making electrical connection with the corresponding electrical connection ring 101. Other parts are wrapped with insulating skin and maintain an insulating relationship with other electrical connection rings 101. As Figure 3 shown, the side wall of its collecting block 5 is provided with more than A wire grooves 53. The side wall of the wire groove 53 abuts against the side wall of the groove body 4. The wire groove 53 is axially offset from the through hole 51 so that the first wire 3 enters the through hole 51 after passing through the wire groove 53.

[0036] Furthermore, a boss 71 is provided on the outer side wall of the conductive ring 7, and a conductive hole 72 for electrically connecting the first wire 3 is provided in the boss 71.

[0037] Adopting the foregoing technical solution, by providing the boss 71 on the outer side wall of the conductive ring 7, the first wire 3 is directly electrically connected to the conductive hole 72 on the boss 71, which facilitates the electrical connection method. Compared with directly using welding or other methods for electrical connection on the side wall, welding in the specifically provided holes is more stable and convenient. And due to the setting of the boss 71, a space for the first wire 3 to pass through can be generated between the electrical connection ring 101 and the groove body 4, making the subsequent installation smoother. Moreover, the cooperation between the boss 71 and the groove body 4 will cause less damage to the first wire 3 compared to directly welding on the side wall of the conductive ring 7 without the boss 71, avoiding pressing the first wire 3 and being more conducive to the installation of the socket 1.

[0038] Specifically, the diameter of the groove body 4 is the sum of the diameter of the boss 71 and the diameter of the conductive ring 7, so that the conductive ring 7 can be adapted to the groove body 4. And a plurality of avoidance grooves 74 for passing other first wires 3 are provided on the side wall of the conductive ring 7, so that the boss 71 can provide a space for accommodating the first wire 3 and allow the first wire 3 to pass through smoothly therein.

[0039] Furthermore, a ring groove 73 is provided on the inner wall of the conductive ring 7, and the electrical connection ring 2 is arranged in the ring groove 73.

[0040] Adopting the foregoing technical solution, the ring groove 73 can play a role in positioning and limiting the electrical connection ring 2, enabling the electrical connection ring 2 to be stably located at the set position and avoiding unnecessary displacement during use (especially during operations such as plugging and unplugging, relative rotation of the plug 10, etc.), thereby ensuring the stability and reliability of the electrical connection and ensuring that it can always make good contact with the plug 10 to achieve electrical signal transmission.

[0041] Furthermore, the first wire 3 in the collecting cavity 52 is fixed to the collecting block 5 by glue sealing.

[0042] Adopting the foregoing technical solution, the glue sealing and fixing can enhance the stability of the first wire 3 in the converging cavity 52, preventing it from loosening, shifting or even detaching from its original connection position due to external forces (such as the external forces generated by vibration, plugging and unplugging during the operation of the rotary connector), ensuring the integrity of the entire electrical connection circuit and the continuous and stable transmission of electrical signals. The glue sealing can play a certain insulating role, avoiding electrical faults such as short circuits caused by accidental contact between different wires, further improving the electrical safety during the use of the rotary connector and enabling it to work reliably under relatively complex working conditions.

[0043] Further, a detachable end cap 8 is provided at the opening of the groove body 4, and one end of the end cap 8 abuts against the conductive ring 7.

[0044] Adopting the foregoing technical solution, firstly, the detachable design facilitates operations such as the installation, debugging, maintenance and repair of the components in the groove body 4. When it is necessary to check or replace components such as the conductive ring 7, the electrical connection ring 2, and the first wire 3, the end cap 8 can be easily disassembled, with convenient operation, which helps to improve the usability and maintainability of the entire rotary connector. Moreover, the end cap 8 abuts against the conductive ring 7, which can play a certain role in fixing and limiting the conductive ring 7, avoiding axial displacement of the conductive ring 7 during use, ensuring its stable position, and further guaranteeing the reliability of the first wire 3 electrically connected thereto, and ensuring the normal transmission of electrical signals.

[0045] Specifically, the end cap 8 has a central hole with the same aperture as that of the electrical connection ring 101.

[0046] Further, a retaining ring 21 for holding the electrical connection ring 2 in the connection groove 11 is inserted into the electrical connection ring 2.

[0047] Adopting the foregoing technical solution can play a stabilizing role on the electrical connection ring 2, preventing the electrical connection ring 2 from accidentally slipping out of the connection groove 11 during use, especially when the plug 10 is frequently plugged and unplugged and rotates relative to the socket 1, ensuring that it always remains in the correct position, and guaranteeing its continuous good contact with the plug 10 to achieve stable electrical signal transmission. Moreover, the presence of the retaining ring 21 makes the structural integrity of the electrical connection ring 2 stronger, helping to maintain the shape and elastic properties of the electrical connection ring 2 itself, enabling it to better deform to fit the plug 10 and ensure the electrical connection function under the conditions of being extruded and stretched by external forces, and improving the working reliability of the entire rotary connector.

[0048] Further, a partial line segment of the first wire 3 passing through the socket 1 is fixed to the socket 1 by a wire fixing glue 81.

[0049] Adopting the foregoing technical solution, firstly, the stability is enhanced. The wire-fixing glue 81 can firmly fix the wire, preventing it from shaking or shifting due to external forces such as vibration generated during the operation of the rotary connector and plugging / unplugging actions in the socket 1, ensuring that the wire is always in the correct connection position, and ensuring the stable and reliable transmission of the electrical signal line. Secondly, the safety is improved, which can prevent electrical faults such as short circuits caused by accidental mutual contact and friction between wires, ensuring the electrical safety of the entire rotary connector during use and enabling it to better adapt to different working conditions.

[0050] Specifically, the wire-fixing glue 81 can also fix the collecting block 5 and the socket 1 to each other.

[0051] Furthermore, a fixing ring 9 connected to the drilling equipment is provided on the side of the socket 1 away from the plug 10, and the fixing ring 9 and the socket 1 are connected by an elastic member 91.

[0052] Adopting the foregoing technical solution, firstly, by using the buffering effect of the elastic member 91, when the drilling equipment generates vibrations, impacts, etc. during operation, these external forces can be effectively absorbed, preventing the external forces from being directly transmitted to the socket 1 and the electrical connection components inside it, thereby protecting the stability of the electrical connection structure and preventing problems such as loosening and poor contact of the electrical connection caused by severe vibrations and impacts, and ensuring the reliable transmission of the electrical signal. Secondly, the connection of the elastic member 91 enables the socket 1 to have the ability of adaptive adjustment within a certain range. When the drilling equipment has slight changes in position or angle due to changes in working conditions, etc., the socket 1 can adjust flexibly accordingly, ensuring that the relative position and connection state between it and the plug 10 remain good, and reducing the impact on the electrical connection caused by factors such as relative displacement of the equipment. Thirdly, it is convenient for installation and disassembly. Compared with the rigid connection method, this form of connection through the elastic member 91 is more convenient to operate when assembling the socket 1 and the fixing ring 9 to the drilling equipment. Subsequently, if maintenance or replacement of the socket 1 or related components is required, it is also easier to disassemble, improving the convenience of the entire usage process.

[0053] A rotary connector includes the above-mentioned socket 1 and also includes a plug 10. An electrical connection ring 101 corresponding to the electrical connection circle 2 is sleeved on the plug 10. The electrical connection rings 101 are respectively electrically connected to a different second wire 102. When the plug 10 is inserted into the socket 1, the electrical connection circle 2 and the electrical connection ring 101 are electrically connected, so that the first wire 3 and the second wire 102 are electrically connected.

[0054] Adopting the foregoing technical solution, this solution abandons the slip ring and brush combination that is prone to wire jumping in the traditional integrated structure, and adopts the method of mutual cooperation between the electrical connection ring 101 of the plug 10 and the electrical connection coil 2 of the socket 1. Each electrical connection ring 101 is electrically connected to a different second wire 102, corresponding one by one to the corresponding electrical connection coil 2 on the socket 1. The circuit connection is clear, facilitating troubleshooting, maintenance and repair. When a fault occurs, the problem can be quickly located, improving the maintenance efficiency. The plug 10 and the socket 1 are plugged in to achieve electrical connection. The operation is simple and efficient, convenient for actual plugging and unplugging, meeting the convenience requirements, and reducing the production and assembly costs. During operation, even in complex working conditions such as relative rotation between the plug 10 and the socket 1 and plugging and unplugging at a certain angle, the continuous and smooth transmission of electrical signals can be ensured, improving the applicability and comprehensive cost performance of the rotary connector in different scenarios.

[0055] It can be understood that in other embodiments, the connection groove 11 can be of various shapes, such as circular, square, etc., but the contacts for electrical connection of the electrical connection coil 2 need to be arranged on the side wall of the connection cavity, and the contacts of the connection part can contact the outer peripheral surface of the plug 10 when the plug 10 and the socket 1 are plugged in. The socket 1 can also be a structure similar to a keyhole, and the contacts of each electrical connection coil 2 can move up and down like the pins in a pin tumbler lock, so that the contacts can contact the circumferential surface of the plug 10, or the circumferential surfaces with different outer diameters on the plug 10. All of these are within the protection scope of this solution.

[0056] In addition to the above preferred embodiments, the present application has other implementation manners. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present application.
