Description

Technical Field

[0001] The present invention particularly relates to a cable connector. Background Art

[0002] Wire rope is a commonly used accessory in the industrial field, and is widely used in connection, lifting, transmission, bundling and other occasions. In particular, wire rope is widely used in the field of lifting and transportation technology.

[0003] Wire ropes are usually purchased in coils and cut to the required length. In some cases, multiple sections of wire ropes need to be fixedly connected, which is usually achieved by using rope rings and rope clamps; in some cases, multiple sections of wire ropes need to be connected to each other so that they can rotate relative to each other, which is usually achieved by using rotary connectors.

[0004] The existing rotary connector has the ends of the wire rope fixed at both ends, and has a structure similar to a thrust bearing in the middle, which relies on a large number of steel balls to achieve the relative free rotation between the two connector sections. Since the rotary connection structure of the multi-steel ball transmission is relatively complex, the overall size of the existing rotary connector is relatively large, which makes it difficult to be used in small spaces for micro-sized cables (for example, cables with a diameter of less than 1 mm). Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a cable connector in view of the above-mentioned deficiencies in the prior art. The cable connector can be used to connect two cables of any diameter without considering the diameter of the cables, and the two cables can be rotated relative to each other to effectively release the torsional stress and deformation on the cables, which helps to reduce the space occupied by the cable connector.

[0006] In the first aspect, an embodiment of the present invention provides a cable connector for connecting a first cable and a second cable, the cable connector comprising a connector body, a first connector and a second connector. The two ends of the connector body are respectively provided with a first accommodating cavity and a second accommodating cavity, and the end surfaces of the two ends are respectively provided with a first through hole and a second through hole, the first through hole is connected to the first accommodating cavity, and the second through hole is connected to the second accommodating cavity. The first connector is arranged in the first accommodating cavity, the first connector can rotate around the axis of the connector body, and the aperture of the first through hole is set to limit the first connector in the first accommodating cavity; one end of the first cable passes through the first through hole and is connected to the first connector. The second connector is arranged in the second accommodating cavity, the second connector can rotate around the axis of the connector body, and the aperture of the second through hole is set to limit the second connector in the second accommodating cavity; one end of the second cable passes through the second through hole and is connected to the second connector.

[0007] In some embodiments, the first connecting member and the second connecting member are both spherical in shape; the first accommodating cavity and the second accommodating cavity are both cylindrical in shape. The radial dimension of the first accommodating cavity is the same as the outer diameter dimension of the first connecting member; and / or the radial dimension of the second accommodating cavity is the same as the outer diameter dimension of the second connecting member.

[0008] In some embodiments, the first accommodating cavity is filled with a lubricant; and the second accommodating cavity is filled with a lubricant.

[0009] In some embodiments, the length of the first accommodating cavity is greater than the outer diameter of the first connecting member; the length of the second accommodating cavity is greater than the outer diameter of the second connecting member.

[0010] In some embodiments, the outer diameter of the first cable is d 1 , the diameter of the first through hole is H 1 , 1.1d 1 ≤H 1 ≤1.2d 1 ; and / or, the outer diameter of the second cable is d 2 , the diameter of the second through hole is H 2 , 1.1d 2 ≤H 2 ≤1.2d 2 .

[0011] In some embodiments, the first connector is fixed to the first cable by welding or crimping; and / or the second connector is fixed to the second cable by welding or crimping.

[0012] In some embodiments, the connector body includes a sleeve, a first sleeve, and a second sleeve. The first sleeve is fixed at one end of the sleeve; the first sleeve and the sleeve form the first accommodating cavity, and the first through hole is provided on the end surface of the first sleeve away from the sleeve. The second sleeve is fixed at the other end of the sleeve; the second sleeve and the sleeve form the second accommodating cavity, and the second through hole is provided on the end surface of the second sleeve away from the sleeve.

[0013] In some embodiments, a first annular groove and a second annular groove are respectively provided at both ends of the sleeve, the first sleeve is clamped in the first annular groove, and the second sleeve is clamped in the second annular groove.

[0014] In some embodiments, the envelope has an inner core and a shell, the shell is located outside the inner core; the first annular groove and the second annular groove are formed between the shell and the inner core; the first sleeve and the second sleeve are respectively sleeved on both ends of the inner core. At each end of the envelope, the inner core extends out of the shell.

[0015] Thus, the cable connector in the embodiment of the present invention, by respectively setting the first accommodating cavity and the second accommodating cavity at the two ends of the connector body, and respectively setting the first through hole communicating with the first accommodating cavity and the second through hole communicating with the second accommodating cavity on the end faces of the two ends, can limit the first connector in the first accommodating cavity through the first through hole, and limit the second connector in the second accommodating cavity through the second through hole. After one end of the first cable passes through the first through hole and is connected to the first connector, the first cable can be connected to the connector body together, and after one end of the second cable passes through the second through hole and is connected to the second connector, the second cable can be connected to the connector body together, so the connection between the first cable and the second cable can be achieved through the connector body. Moreover, when the outer diameter of the first cable and the second cable changes, the size of the first connector and the second connector, the size of the first accommodating cavity and the second accommodating cavity, and the size of the first through hole and the second through hole can be adjusted accordingly to achieve the connection between the first cable and the second cable of any size, so the cable connector can be suitable for the connection of cables of any size. By enabling the first connector to rotate around the axis of the connector body and the second connector to rotate around the axis of the connector body, the first cable connected to the first connector and the second cable connected to the second connector can both rotate relative to the connector body, thereby achieving relative rotation between the first cable and the second cable and effectively releasing the torsional stress and deformation on the cables. Compared with the prior art, the cable connector does not need to be provided with a structure similar to a thrust bearing, which helps to reduce the space occupied by the cable connector and enables the cable connector to adapt to the narrow space usage of small-sized cables.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Embodiment 1:

[0021] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a cable connector, which is applied in the engineering field and is used to connect a first cable 1 and a second cable 2. The cable connector includes a connector body 3, a first connector 6 and a second connector 7. The two ends of the connector body 3 are respectively provided with a first accommodating cavity 4 and a second accommodating cavity 5, and the end surfaces of the two ends are respectively provided with a first through hole and a second through hole, the first through hole is connected to the first accommodating cavity 4, and the second through hole is connected to the second accommodating cavity 5. The first connector 6 is arranged in the first accommodating cavity 4, the first connector 6 can rotate around the axis of the connector body 3, and the aperture of the first through hole is set to limit the first connector 6 in the first accommodating cavity 4; one end of the first cable 1 passes through the first through hole and is connected to the first connector 6. The second connector 7 is arranged in the second accommodating cavity 5, the second connector 7 can rotate around the axis of the connector body 3, and the aperture of the second through hole is set to limit the second connector 7 in the second accommodating cavity 5; one end of the second cable 2 passes through the second through hole and is connected to the second connector 7.

[0022] Exemplarily, the first cable 1 and the second cable 2 may be rigid cables or flexible cables.

[0023] Exemplarily, the material of the first cable 1 and the second cable 2 may include steel, aluminum, etc., and the present invention is not limited thereto. For example, the first cable 1 and the second cable 2 may both be steel wire ropes.

[0024] The diameters of the first cable 1 and the second cable 2 may be of any size.

[0025] The materials, sizes, etc. of the first cable 1 and the second cable 2 may be completely the same or different.

[0026] Exemplarily, the shape of the connector body 3 may be a cylinder, a cuboid, or the like.

[0027] Exemplarily, the first accommodating chamber 4 and the second accommodating chamber 5 may be interconnected or independent of each other.

[0028] Exemplarily, the shape of the first accommodating cavity 4 may be a cylinder, the shape of the first connecting member 6 may also be a cylinder, the axial directions of the two cylinders are the same, and the first connecting member 6 can rotate in the first accommodating cavity 4; or, the shape of the first accommodating cavity 4 may be a cylinder, the shape of the first connecting member 6 may be a cone, the axial directions of the cylinder and the cone are the same, and the first connecting member 6 can also rotate in the first accommodating cavity 4, so that the first cable 1 can rotate relative to the connector body 3 after being connected to the first connecting member 6. Alternatively, the shape and arrangement of the first accommodating cavity 4 and the first connecting member 6 may also be other forms, and the present invention is not limited thereto.

[0029] The second accommodating cavity 5 and the second connecting member 7 may be arranged in a manner similar to that of the first accommodating cavity 4 and the first connecting member 6 , so that the second cable 2 can rotate relative to the connector body 3 after being connected to the second connecting member 7 .

[0030] Thereby, relative rotation between the first cable 1 and the second cable 2 can be achieved.

[0031] The first connecting member 6 and the second connecting member 7 have high hardness. For example, the first connecting member 6 and the second connecting member 7 are made of martensitic steel.

[0032] With such an arrangement, the wear of the first connecting member 6 when rotating in the first accommodating chamber 4 can be reduced, and deformation or damage of the first connecting member 6 can be avoided, so as to maintain a stable and firm connection with the first cable 1 and withstand the tension on the first cable 1; similarly, the wear of the second connecting member 7 when rotating in the second accommodating chamber 5 can be reduced, and deformation or damage of the second connecting member 7 can be avoided, so as to maintain a stable and firm connection with the second cable 2 and withstand the tension on the second cable 2.

[0033] Exemplarily, in the radial direction of the connector body 3, the aperture size of the first through hole is smaller than the maximum size of the first connecting member 6 to prevent the first connecting member 6 from sliding out of the first accommodating chamber 4 through the first through hole; the aperture size of the second through hole is smaller than the maximum size of the second connecting member 7 to prevent the second connecting member 7 from sliding out of the second accommodating chamber 5 through the second through hole.

[0034] Through the above arrangement, the first cable 1 and the second cable 2 can be connected through the connector body 3, and the first cable 1 and the second cable 2 can rotate relative to each other.

[0035] It can be understood that for any size of the first cable 1 and the second cable 2, the connection between the first cable 1 and the second cable 2 of any size can be achieved by correspondingly adjusting the size of the first connecting member 6 and the second connecting member 7, the size of the first accommodating cavity 4 and the second accommodating cavity 5, and the size of the first through hole and the second through hole.

[0036] Therefore, the cable connector has the following advantages: simple structure and low difficulty in processing and manufacturing; reasonable structural design, able to effectively bear and transmit cable tension; compact structure and small size, able to adapt to the narrow space use of small-size cables; able to effectively realize relative rotation between multiple sections of cables, and will not generate long-term torsional force on the cables, thereby avoiding cable twisting, strand separation and other phenomena.

[0037] Therefore, the cable connector in the embodiment of the present invention, by respectively providing the first accommodating chamber 4 and the second accommodating chamber 5 at the two ends of the connector body 3, and respectively providing the first through hole communicating with the first accommodating chamber 4 and the second through hole communicating with the second accommodating chamber 5 on the end faces of the two ends, can limit the first connector 6 in the first accommodating chamber 4 through the first through hole, and limit the second connector 7 in the second accommodating chamber 5 through the second through hole. After one end of the first cable 1 passes through the first through hole and is connected to the first connector 6, the first cable 1 can be connected to the connector body 3, and after one end of the second cable 2 passes through the second through hole and is connected to the second connector 7, the second cable 2 can be connected to the connector body 3, so the connection between the first cable 1 and the second cable 2 can be achieved through the connector body 3. Moreover, when the outer diameters of the first cable 1 and the second cable 2 change, the sizes of the first connector 6 and the second connector 7, the sizes of the first accommodating chamber 4 and the second accommodating chamber 5, and the sizes of the first through hole and the second through hole can be adjusted accordingly to achieve the connection between the first cable 1 and the second cable 2 of any size, so the cable connector can be suitable for the connection of cables of any size. By enabling the first connector 6 to rotate around the axis of the connector body 3 and the second connector 7 to rotate around the axis of the connector body 3, the first cable 1 connected to the first connector 6 and the second cable 2 connected to the second connector 7 can both rotate relative to the connector body 3, thereby achieving relative rotation between the first cable 1 and the second cable 2 and effectively releasing the torsional stress and deformation on the cables. Compared with the prior art, the cable connector does not need to be provided with a structure similar to a thrust bearing, which helps to reduce the space occupied by the cable connector and enables the cable connector to be adapted to the use occasions of narrow spaces.

[0038] In some embodiments, in combination Figure 2 and Figure 3 The first connecting member 6 and the second connecting member 7 are both spherical in shape; the first accommodating cavity 4 and the second accommodating cavity 5 are both cylindrical in shape. The radial dimension of the first accommodating cavity 4 is the same as the outer diameter dimension of the first connecting member 6.

[0039] For example, Figure 3 As shown, the outer diameter of the first connecting member 6 is D, and the radial dimension of the first accommodating cavity 4 is D.

[0040] That is, the first accommodating cavity 4 is used to cooperate with the first connecting member 6, and a clearance fit processing relationship is adopted between the first accommodating cavity 4 and the first connecting member 6, and the main dimensions of the first accommodating cavity 4 and the first connecting member 6 are both equal to D.

[0041] Through the above arrangement, the first connecting member 6 is in full contact with the inner wall of the first accommodating chamber 4, which can prevent the first connecting member 6 from being displaced in the radial direction of the first accommodating chamber 4, thereby preventing the first cable 1 from being displaced in the radial direction of the first accommodating chamber 4 and maintaining the stability of the position of the first cable 1.

[0042] In some examples, the shape of one end of the first accommodating cavity 4 that contacts the first connecting member 6 is hemispherical, and the shape of the hemispherical shape matches the shape of the first connecting member 6 .

[0043] In this way, when a pulling force is applied to the first cable 1, the contact area between the first connecting member 6 and the outer wall of the first accommodating cavity 4 can be increased, which is beneficial to disperse the stress between the first connecting member 6 and the connector body 3, reduce the wear of the first connecting member 6 and the connector body 3, and increase the service life of the first connecting member 6 and the connector body 3.

[0044] In some examples, the shape of one end of the second accommodating cavity 5 that contacts the second connecting member 7 is hemispherical, and the shape of the hemispherical shape matches the shape of the second connecting member 7 .

[0045] It can be understood that the above arrangement can also reduce the wear of the second connecting member 7 and the connector body 3 , and increase the service life of the second connecting member 7 and the connector body 3 .

[0046] like Figure 2 As shown, the radial dimension of the second accommodating cavity 5 is the same as the outer diameter of the second connecting member 7 .

[0047] Exemplarily, the second accommodating cavity 5 is used to cooperate with the second connecting member 7, and a clearance fit processing relationship is adopted between the second accommodating cavity 5 and the second connecting member 7, and the main dimensions of the second accommodating cavity 5 and the second connecting member 7 are equal.

[0048] Similar to the first accommodating cavity 4 and the first connecting member 6 , the above arrangement can maintain the stability of the position of the second cable 2 .

[0049] In some embodiments, the first accommodating chamber 4 is filled with a lubricant; and the second accommodating chamber 5 is filled with a lubricant.

[0050] Exemplarily, lubricants include graphite, butter, molybdenum disulfide and the like.

[0051] Through the above arrangement, the first connecting member 6 can be lubricated to reduce the resistance of the first connecting member 6 when it rotates in the first accommodating chamber 4; the second connecting member 7 can be lubricated to reduce the resistance of the second connecting member 7 when it rotates in the second accommodating chamber 5; thereby reducing the wear of the first connecting member 6 and the second connecting member 7, and reducing the resistance of the first cable 1 and the second cable 2 when they rotate relative to each other.

[0052] In some embodiments, Figure 2 and Figure 3 As shown, the length of the first accommodating cavity 4 is greater than the outer diameter of the first connecting member 6 ; the length of the second accommodating cavity 5 is greater than the outer diameter of the second connecting member 7 .

[0053] For example, the outer diameter D of the first connecting member 6 is 20 mm, and the length of the first accommodating chamber 4 is 30 mm, and a free space of 10 mm is provided between the first connecting member 6 and the distal end of the first accommodating chamber 4. Alternatively, the outer diameter D of the second connecting member 7 is 15 mm, and the length of the second accommodating chamber 5 is 20 mm, and a free space of 5 mm is provided between the second connecting member 7 and the distal end of the second accommodating chamber 5.

[0054] Through the above arrangement, more free space can be provided in the first accommodating chamber 4 to accommodate the lubricant, and more free space can be provided in the second accommodating chamber 5 to accommodate more lubricant. Therefore, the lubricant can lubricate the first connecting member 6 and the second connecting member 7 for a long time, thereby increasing the maintenance interval of the cable connector.

[0055] In practical applications, the lengths of the first accommodating chamber 4 and the second accommodating chamber 5 can be set according to the content of the lubricant that needs to be set.

[0056] In some embodiments, Figure 2 As shown, the outer diameter of the first cable 1 is d 1 , the diameter of the first through hole is H 1 , 1.1d 1 ≤H 1 ≤1.2d 1 .

[0057] For example, the outer diameter d of the first cable 1 is 1 is 10 mm, and the diameter of the first through hole is H 1 , then 11mm≤H 1 ≤12mm, i.e. the diameter H of the first through hole 1 It can be 11mm, 11.5mm or 12mm, etc.

[0058] like Figure 2As shown, the above arrangement enables the first cable 1 to smoothly pass through the first through hole, ensures the free tilt or rotation of the first cable 1 relative to the connector body 3, and appropriately leaves movement space for the connection (e.g., weld) between the first cable 1 and the first connector 6. The above arrangement also reduces the gap between the first cable 1 and the outer wall of the first through hole, ensures that the connector body 3 has sufficient bearing area for the first connector 6, and avoids the first cable 1 from swinging around the connector body 3, which is conducive to maintaining the relative stability between the first cable 1 and the connector body 3, thereby limiting the tilt angle between the first cable 1 and the second cable 2 to a certain extent.

[0059] In some examples, the outer diameter of the second cable 2 is d 2 , the diameter of the second through hole is H 2 , 1.1d 2 ≤H 2 ≤1.2d 2 .

[0060] For example, the outer diameter d of the second cable 2 is 2 is 20 mm, and the diameter of the second through hole is H 2 , then 22mm≤H 2 ≤24mm, i.e. the diameter H of the first through hole 2 It can be 22mm, 23mm or 24mm, etc.

[0061] Similarly, the above arrangement enables the second cable 2 to pass through the second through hole smoothly, ensures the free tilt or rotation of the second cable 2 relative to the connector body 3, and appropriately leaves movement space for the connection (such as the weld) between the second cable 2 and the second connector 7. The above arrangement also reduces the gap between the second cable 2 and the outer wall of the second through hole, ensures that the connector body 3 has sufficient bearing area for the second connector 7, and avoids the second cable 2 from swinging around the connector body 3, which is conducive to maintaining the relative stability between the second cable 7 and the connector body 3, thereby limiting the tilt angle between the first cable 1 and the second cable 2 to a certain extent.

[0062] Therefore, the relative stability between the first cable 1 and the second cable 7 can be maintained, and the swing amplitude between the first cable 1 and the second cable 7 can be reduced.

[0063] In some embodiments, the first connector 6 is fixed to the first cable 1 by welding or crimping.

[0064] like Figure 3 As shown, the first connector 6 is fixed to the first cable 1 by welding, and the weld surrounds the connection between the first connector 6 and the first cable 1. Welding fixation has the advantages of reliable connection and convenient on-site construction.

[0065] Crimping is the process of applying pressure to tightly connect two or more parts. Crimping has the advantages of reliable connection, easy operation, and basically no change in the external dimensions.

[0066] In some examples, the second connector 7 is fixed to the second cable 2 by welding or crimping.

[0067] This arrangement has the same beneficial effects as the first connecting member 6 and the first cable 1 .

[0068] In some examples, the first cable 1 and the second cable 2 are the same cable. In this case, the first connector 6 and the second connector 7 can be set to the same shape and size, and the connector body 3 can be set to a shape that is symmetrical at both ends. This can reduce the difficulty of designing and manufacturing the first connector 6, the second connector 7 and the connector body 3, and facilitate installation.

[0069] In some embodiments, Figure 1 and Figure 2 As shown, the connector body 3 includes a sleeve 8, a first sleeve 9 and a second sleeve 10. The first sleeve 9 is fixed at one end of the sleeve 8; the first sleeve 9 and the sleeve 8 form a first accommodating cavity 4, and the first through hole is arranged on the end surface of the first sleeve 9 away from the sleeve 8. The second sleeve 10 is fixed at the other end of the sleeve 8; the second sleeve 10 and the sleeve 8 form a second accommodating cavity 5, and the second through hole is arranged on the end surface of the second sleeve 10 away from the sleeve 8.

[0070] Exemplarily, the first sleeve 9 and the second sleeve 10 are completely identical, which can reduce the difficulty of processing the first sleeve 9 and the second sleeve 10.

[0071] There are many ways to fix the first sleeve 9, the second sleeve 10 and the envelope 8.

[0072] Exemplarily, the first sleeve 9 and the second sleeve 10 are both fixed to the sleeve 8 by welding, or the first sleeve 9 and the second sleeve 10 are both fixed to the sleeve 8 by threaded connection.

[0073] The above arrangement facilitates the production of the sealing sleeve 8 , the first sleeve 9 and the second sleeve 10 , thereby facilitating the on-site installation and disassembly of the connector body 3 .

[0074] In some embodiments, Figure 1 and Figure 2 As shown, a first annular groove and a second annular groove are respectively provided at both ends of the envelope 8. The first sleeve 9 is clamped in the first annular groove, and the second sleeve 10 is clamped in the second annular groove.

[0075] Exemplarily, the first annular groove matches the first sleeve 9 , and the second annular groove matches the second sleeve 10 .

[0076] After the first sleeve 9 extends into the first annular groove, it can be positioned with the envelope 8, which is convenient for fixing the first sleeve 9 on the envelope 8. After the second sleeve 10 extends into the second annular groove, it can be positioned with the envelope 8, which is convenient for fixing the second sleeve 10 on the envelope 8.

[0077] In some embodiments, Figure 1 and Figure 2 As shown, the envelope 8 has an inner core 11 and a shell 12, the shell 12 is located outside the inner core 11; a first annular groove and a second annular groove are formed between the shell 12 and the inner core 11; a first sleeve 9 and a second sleeve 10 are respectively sleeved on both ends of the inner core 11. At each end of the envelope 8, the inner core 11 extends out of the shell 12.

[0078] Through the above arrangement, the inner core 11 can support the first sleeve 9 and the second sleeve 10 in the radial direction, thereby reducing the shaking of the first sleeve 9 and the second sleeve 10 in the radial direction.

[0079] Moreover, when the first sleeve 9 and the second sleeve 10 are fixedly connected to the envelope 8 by welding, a fillet weld is applied at the connection between the shell 12 and the outer walls of the first sleeve 9 and the second sleeve 10. The inner core 11 can act as a support plate for the weld, so that the welding quality is better and it is not easy to have welding leakage or welding penetration on the outer walls of the first sleeve 9 and the second sleeve 10.

[0080] In this case, the steps for connecting the first cable 1 and the second cable 2 are as follows:

[0081] The first step: connect the rope end of the first cable 1 to the first connector 6 by welding, crimping, etc.; connect the rope end of the second cable 2 to the second connector 7 by welding, crimping, etc.

[0082] Step 2: insert the first cable 1 together with the first connector 6 into the first sleeve 9 , so that the first cable 1 passes through the first through hole of the first sleeve 9 , and the first connector 6 is located inside the first sleeve 9 .

[0083] Step 3: insert the second cable 2 together with the second connecting member 7 into the second sleeve 10 , so that the second cable 2 passes through the second through hole of the second sleeve 10 , and the second connecting member 7 is located inside the second sleeve 10 .

[0084] Step 4: Fill lubricants into the first sleeve 9 and the second sleeve 10. The type of lubricants can be graphite, butter, molybdenum disulfide and other materials as needed.

[0085] Step 5: Use the sleeve 8 to connect the first sleeve 9 and the second sleeve 10, and use welding or threaded connection to connect the sleeve 8 to the first sleeve 9 and the second sleeve 10 respectively.

[0086] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
