Description

Technical Field

[0001] This utility model relates to the field of cable threading technology, and in particular to a threading device. Background Technology

[0002] In some devices, it is necessary to extend internal cables to the outside to enable electrical connections between the device and external components and / or power sources. For example, in a liquid-cooled pump, power and data cables need to be extended from the pump body to allow for electrical connections between the pump and external controllers and power supplies, respectively. To ensure the device's airtightness and prevent external liquids, dust, etc., from entering, rubber seals are installed at the cable entry points. Cables pass through these seals and extend to the outside of the device.

[0003] In the existing technology, cables are manually threaded one by one through the rubber seal. Since the inner diameter of the threading hole on the rubber seal is smaller than the outer diameter of the cable, it is laborious and inefficient to thread the cables. It may even damage the rubber seal or the cable, resulting in a low threading yield. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a threading device that can improve threading efficiency and threading yield.

[0005] This utility model embodiment provides a threading device, which includes:

[0008] The lead wire mechanism is located on one side of the mounting base and connected to the platform. The lead wire mechanism includes a lead wire tube for passing through a wire hole in the seal and guiding the cable out of the wire hole from the lead wire tube.

[0009] The cable pulling mechanism is located on the other side of the mounting base and is movably connected to the platform. The cable pulling mechanism can move toward or away from the mounting base. The cable pulling mechanism is used to fix the cable passing through the cable hole and pull the cable.

[0010] The threading device according to the embodiments of the present utility model has at least the following beneficial effects:

[0011] Firstly, by setting up a lead tube, after the lead tube passes through the wire hole in the seal, the lead tube can, to a certain extent, expand the wire hole radially and guide the cable, allowing the cable to smoothly pass through the lead tube and exit the wire hole, avoiding damage to the seal or the cable during insertion. Secondly, by setting up a cable pulling mechanism, the cable pulling mechanism can pull the cable exiting the wire hole, facilitating its continued exit. Simultaneously, since the cable exiting the wire hole is fixed to the cable pulling mechanism, pulling the lead tube out of the wire hole prevents it from moving the cable, keeping the cable in its final position after pulling. Therefore, the cable threading device of this embodiment improves threading efficiency and yield, resulting in better product consistency.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] like Figure 1 As shown, this embodiment of the utility model provides a threading device 100 for assisting the cable 200 in threading through the sealing member 300.

[0042] The threading device 100 includes a platform 10, a mounting base 20, a wire guiding mechanism 30, and a wire pulling mechanism 40. The platform 10 is used to support the mounting base 20, the wire guiding mechanism 30, and the wire pulling mechanism 40.

[0043] Mounting base 20 is connected to platform 10 and is used to mount seal 300.

[0044] Please combine Figure 2 The lead wire mechanism 30 is located on one side of the mounting base 20 and connected to the platform 10. The lead wire mechanism 30 includes a lead wire tube 31, which is used to pass through the wire hole 301 in the seal 300 and guide the cable 200 out of the wire hole 301 from the lead wire tube 31.

[0045] The cable pulling mechanism 40 is located on the other side of the mounting base 20 and is movably connected to the platform 10. The cable pulling mechanism 40 can move toward or away from the mounting base 20. The cable pulling mechanism 40 is used to fix the cable 200 that passes through the cable hole 301 and pull the cable 200.

[0046] The following is an exemplary description of the use of the threading device 100: First, the sealing member 300 is installed on the mounting base 20, and the lead tube 31 is inserted into the thread hole 301 in the sealing member 300; then, the cable 200 is inserted into the lead tube 31 from the end away from the sealing member 300, and the cable 200 is moved along the lead tube 31 until the cable 200 exits from the other end of the lead tube 31, thereby exiting the thread hole 301; next, the cable 200 that has exited the thread hole 301 is fixed to the wire pulling machine. The cable pulling mechanism 40 is moved away from the mounting base 20. During this process, the cable pulling mechanism 40 will pull the cable 200 to continue to pass through the cable hole 301 until the length of the cable 200 passing through the cable hole 301 meets the usage requirements. Then, the cable pulling mechanism 40 is released from fixing the cable 200, and the lead tube 31 is pulled out from the cable hole 301. Finally, the sealing element 300 and the cable 200 inserted on the sealing element 300 are removed from the mounting base 20, thus completing the insertion of the cable 200 on the sealing element 300.

[0047] In this embodiment of the present invention, firstly, by providing a lead tube 31, after the lead tube 31 is inserted into the wire hole 301 in the sealing member 300, the lead tube 31 can, to a certain extent, expand the wire hole 301 radially and guide the cable 200, so that the cable 200 can smoothly pass through the lead tube 31 and exit the wire hole 301, avoiding damage to the sealing member 300 or the cable 200 during the insertion process; secondly, by providing a wire pulling mechanism 40, the wire pulling mechanism 40 can pull the cable 200 that has exited the wire hole 301, making it convenient for the cable 200 to continue to exit the wire hole 301. At the same time, since the cable 200 that has exited the wire hole 301 is fixed on the wire pulling mechanism 40, when the lead tube 31 is pulled out of the wire hole 301, it can prevent the lead tube 31 from driving the cable 200 to move, so that the cable 200 can be kept in the position after the wire pulling is completed. Therefore, the threading device 100 of this utility model embodiment improves threading efficiency and threading yield, and has better product consistency.

[0048] Understandably, the number of lead tubes 31 can be set according to actual needs, with only one required. One lead tube 31 is inserted into a corresponding wire hole 301. That is, the number of lead tubes 31 corresponds to the number of wire holes 301 reserved in the seal 300.

[0049] Optionally, the number of lead tubes 31 is two or more, that is, the number of wire passage holes 301 reserved in the sealing element 300 is two or more, and one lead tube 31 is inserted into a corresponding wire passage hole 301. For example, if the sealing element 300 has five wire passage holes 301 reserved, that is, when five cables 200 need to be inserted into the sealing element 300, the number of lead tubes 31 is five. Each lead tube 31 can be inserted into the corresponding wire passage hole 301 in the sealing element 300. When threading the wires, each cable 200 passes through each lead tube 31 and exits through the wire passage hole 301. Each cable 200 that exits through the wire passage hole 301 is fixed to the wire pulling mechanism 40 and pulled by the wire pulling mechanism 40. In this way, the threading of five cables 200 on the sealing element 300 can be realized at the same time.

[0050] It is worth noting that the inner diameter of the lead tube 31 can be set according to actual needs. When the outer diameter of the cable 200 that the lead tube 31 needs to pass through is large, the inner diameter of the lead tube 31 can be set to be large. When the outer diameter of the cable 200 that the lead tube 31 needs to pass through is small, the inner diameter of the lead tube 31 can be set to be small.

[0051] In some embodiments, the seal 300 may be an elastic sealing structure, such as a rubber component; the lead tube 31 may be a rigid structure, such as a copper tube.

[0052] like Figure 1 As shown, in some embodiments, the mounting base 20 is generally plate-shaped and has two largest and opposite surfaces. One side of the mounting base 20 refers to the side facing one of its largest surfaces, and the other side refers to the side facing the other largest surface.

[0053] In other embodiments, the shape of the mounting base 20 can be set according to actual needs and is not limited to the plate shape described above. For example, the mounting base 20 can also be columnar, strip-shaped, etc.

[0054] like Figure 2 As shown, in some embodiments, a mounting groove 21 is defined on the mounting base 20 for mounting the seal 300 and restricting the movement of the seal 300 relative to the mounting base 20.

[0055] Specifically, the mounting groove 21 can restrict the movement of the seal 300 from one side of the mounting base 20 to the other side of the mounting base 20. That is, the mounting groove 21 can restrict the movement of the seal 300 in the direction of the lead tube 31 being inserted into the wire hole 301. In this way, when the lead tube 31 is inserted into the wire hole 301, it can prevent the lead tube 31 from driving the seal 300 to move, so that the seal 300 can be kept in the same position.

[0056] More specifically, the seal 300 includes a first sealing portion 310 and a second sealing portion 320, which are connected. A wire-passing hole 301 passes through the first sealing portion 310 and the second sealing portion 320. The radial dimension of the first sealing portion 310 along the wire-passing hole 301 is larger than the radial dimension of the second sealing portion 320 along the wire-passing hole 301. The mounting groove 21 includes a first groove 211 and a second groove 212, which are sequentially arranged along one side of the mounting base 20 and pointing to the other side of the mounting base 20, and are connected. The groove width of the first groove 211 is larger than the groove width of the second groove 212. The first sealing part 310 is installed in the first slot 211, and the second sealing part 320 is installed in the second slot 212. In this way, the mounting slot 21 can restrict the movement of the sealing member 300 in the direction from the first slot 211 to the second slot 212, that is, restrict the movement of the sealing member 300 from one side of the mounting base 20 to the other side of the mounting base 20.

[0057] The first sealing part 310, the second sealing part 320, the first groove 211 and the second groove 212 are all rectangular. The first sealing part 310 and the first groove 211 are adapted to each other, and the second sealing part 320 and the second groove 212 are adapted to each other.

[0058] Typically, the inner diameter of the wire hole 301 is smaller than the outer diameter of the wire harness. In order for the cable 200 to pass smoothly through the wire hole 301 along the lead tube 31, the inner diameter of the lead tube 31 must be greater than or equal to the outer diameter of the cable 200. Therefore, the outer diameter of the lead tube 31 will be greater than the inner diameter of the wire hole 301. As a result, when the lead tube 31 is inserted into the wire hole 301, it is easy to cause insertion difficulties.

[0059] Please combine Figure 3 In view of this, in some embodiments, the lead tube 31 has an insertion end 311 for passing through the wire hole 301. The insertion end 311 defines a slot 3111, which penetrates the side wall of the insertion end 311 radially and extends to the end face of the insertion end 311 axially. This allows the insertion end 311 to have the ability to easily undergo elastic deformation inward. Thus, during the process of the insertion end 311 entering the wire hole 301, the inner wall of the wire hole 301 can force the insertion end 311 to undergo elastic deformation inward, that is, to undergo radial contraction, so as to reduce the outer diameter of the insertion end 311, thereby facilitating the insertion end 311 to pass through the wire hole 301.

[0060] After the insertion end 311 passes through the wire hole 301, the insertion end 311 can recover its elastic deformation so that the cable 200 can pass through the insertion end 311. At the same time, the part of the lead tube 31 near the insertion end 311 is located in the wire hole 301 and expands the wire hole 301 to a certain extent along the radial direction of the wire hole 301.

[0061] It is understandable that the number of slots 3111 can be set according to actual needs, with at least one slot, so that the insert end 311 can easily undergo elastic deformation to its inner side.

[0062] Optionally, the number of slots 3111 is at least two, and at least two slots 3111 are arranged circumferentially at intervals along the insertion end 311. For example, four slots 3111 are arranged circumferentially at intervals along the insertion end 311.

[0063] like Figure 1 As shown, in some embodiments, the lead wire mechanism 30 further includes a tube connector 32, which is movably connected to the platform 10. The tube connector 32 can move toward or away from the mounting base 20. The lead wire 31 is connected to the tube connector 32. Thus, by moving the tube connector 32, the lead wire 31 can be moved synchronously, making it convenient to insert the lead wire 31 into or pull it out of the wire hole 301 in the seal 300. In addition, by moving the tube connector 32 to move the lead wire 31 away from the mounting base 20, the disassembly and assembly of the seal 300 on the mounting base 20 can be avoided, preventing the lead wire 31 from getting too close to the mounting base 20 and interfering with the disassembly and assembly of the seal 300 on the mounting base 20.

[0064] Optionally, the axial direction of the lead tube 31 coincides with the axial direction of the through hole 301.

[0065] In some embodiments, the threading device 100 further includes a limiting mechanism 50 connected to the platform 10. The limiting mechanism 50 is used to restrict the movement of the tube connector 32 after the lead tube 31 is inserted into the wire passage hole 301. By providing the first limiting structure 51, the threading mechanism 30 can be kept in the same position after the lead tube 31 is inserted into the wire passage hole 301, preventing the lead tube 31 from moving relative to the seal 300.

[0066] In addition, the positioning of the lead tube 31 can also be achieved through the cooperation of the tube connector 32 and the limiting mechanism 50, so that the lead tube 31 is always in the same position after it is inserted into the wire hole 301, with good consistency.

[0067] like Figure 1 and Figure 4As shown, in some embodiments, the limiting mechanism 50 includes a first limiting structure 51, which includes a slide rail 511 and a limiting block 512. The slide rail 511 is connected to the platform 10, and the limiting block 512 is slidably connected to the slide rail 511. The limiting block 512 can slide along the slide rail 511 so that the limiting block 512 extends to the side of the pipe connector 32 away from the mounting base 20, and restricts the movement of the pipe connector 32 away from the mounting base 20, thereby preventing the lead tube 31 from being pulled out of the wire hole 301. When the first limiting structure 51 needs to limit the pipe connector 32, it can be done by sliding the limiting block 512 along the slide rail 511 to the side of the pipe connector 32 away from the mounting base 20. When it is necessary to release the first limiting structure 51 from the pipe connector 32, it can be done by sliding the limiting block 512 along the slide rail 511 to the side of the pipe connector 32 away from the mounting base 20. It is convenient to use and simple to operate.

[0068] And / or, the limiting mechanism 50 includes a second limiting structure 52, which is disposed on the side of the pipe connector 32 facing the mounting base 20 and restricts the pipe connector 32 from moving toward the mounting base 20, thereby preventing the lead pipe 31 from continuing to pass through the wire hole 301.

[0069] like Figure 4 and Figure 5 As shown, in some embodiments, the first limiting structure 51 further includes a driving block 513 and a pin 514. One of the driving block 513 and the limiting block 512 defines a through groove 515. The pin 514 passes through the through groove 515 and is connected to the other of the driving block 513 and the pin 514. The through groove 515 is set at a preset angle with the platform 10, the preset angle being greater than 0° and less than 90°. The driving block 513 can move in a direction perpendicular to the platform 10 and drive the limiting block 512 to slide along the slide rail 511 via the pin 514. With the above configuration, the movement of the driving block 513 in a direction perpendicular to the platform 10 can be converted into the movement of the limiting block 512 along the slide rail 511. In this way, the structure of the first limiting structure 51 in the direction parallel to the platform 10 can be more compact, saving the space occupied by the first limiting structure 51 in the direction parallel to the platform 10.

[0070] When the drive block 513 moves in a direction perpendicular to the platform 10 and away from the platform 10, the drive block 513 can drive the limiting block 512 to slide along the slide rail 511 toward the side of the pipe connector 32 away from the mounting base 20 via the pin 514, so as to restrict the movement of the pipe connector 32 away from the mounting base 20; when the drive block 513 moves in a direction perpendicular to the platform 10 and toward the platform 10, the drive block 513 can drive the limiting block 512 to slide along the slide rail 511 away from the side of the pipe connector 32 away from the mounting base 20 via the pin 514, so as to allow the pipe connector 32 to move away from the mounting base 20.

[0071] Optionally, the preset included angle is 56°, so that when the drive block 513 moves in a direction perpendicular to the platform 10, the limiting block 512 can slide along the slide rail 511 to generate a large displacement.

[0072] In some embodiments, the drive block 513 is U-shaped, and a through groove 515 is defined in the limiting block 512. The through groove 515 extends through the opposite sides of the limiting block 512 in a direction parallel to the platform 10. The two ends of the drive block 513 are located on opposite sides of the limiting block 512, and a pin 514 passes through the through groove 515 and is connected to the two ends of the drive block 513.

[0073] In some embodiments, the first limiting structure 51 further includes a connecting frame 516 and a plug rod 517. The connecting frame 516 includes a guide post 5161, a fixed plate 5162, and a movable plate 5163. The guide post 5161 is connected to the platform 10. The fixed plate 5162 is connected to the end of the guide post 5161 away from the platform 10. The fixed plate 5162 defines a first insertion hole 5164. The movable plate 5163 is slidably connected to the guide post 5161 and connected to the drive block 513. The movable plate 5163 defines a second insertion hole. The plug rod 517 is pluggable and insertable into the second insertion hole.

[0074] When the movable plate 5163 moves along a direction perpendicular to the platform 10 and away from the platform 10 until the first insertion hole 5164 and the second insertion hole are axially opposite each other along the first insertion hole 5164, the insertion rod 517 can pass through the second insertion hole into the first insertion hole 5164, so that the movable plate 5163 is fixed relative to the fixed plate 5162. In this way, the limiting block 512 connected to the movable plate 5163 by the driving block 513 is also fixed relative to the fixed plate 5162, so that the limiting block 512 can be fixed at the position when it extends to the side of the pipe connector 32 away from the mounting base 20.

[0075] When it is necessary to release the fixing of the limit block 512, the plug rod 517 can be pulled out from the first plug hole 5164. It is convenient to use and easy to operate.

[0076] In some embodiments, the insertion rod 517 is provided with an external thread, and the second insertion hole is provided with an internal thread. The external thread and the internal thread are threadedly connected. Thus, by rotating the insertion rod 517, the insertion rod 517 can be inserted into or pulled out of the first insertion hole 5164. Furthermore, the engagement of the external thread and the internal thread can keep the insertion rod 517 in the second insertion hole, preventing the insertion rod 517 from falling out of the second insertion hole.

[0077] Optionally, the axes of the first socket 5164 and the second socket are parallel to each other and both are parallel to the stage 10.

[0078] In some embodiments, the second limiting structure 52 can be a limiting post, which is connected to the platform 10 and located on the side of the pipe connector 32 facing the mounting base 20.

[0079] like Figure 1 As shown, in some embodiments, the cable pulling mechanism 40 includes a first clamping member 41 and a second clamping member 42, which are movably connected. The first clamping member 41 and the second clamping member 42 are used to jointly clamp the cable 200 that passes through the cable hole 301. By making the first clamping member 41 and the second clamping member 42 movably connected, the first clamping member 41 and the second clamping member 42 can move away from each other, so that a receiving space for the cable 200 to extend into is formed between the first clamping member 41 and the second clamping member 42. The first clamping member 41 and the second clamping member 42 can also move towards each other to jointly clamp the cable 200 in the receiving space, thereby fixing the cable 200.

[0080] like Figure 6 As shown, in some embodiments, a groove 411 is defined on one of the sides of the first clamping member 41 facing the second clamping member 42 and the side of the second clamping member 42 facing the first clamping member 41. The inner diameter of the groove 411 is smaller than the outer diameter of the cable 200. The groove 411 is used to limit the engagement with the cable 200 in the radial direction. By providing the groove 411, a portion of the cable 200 can be accommodated in the groove 411 in its radial direction. In this way, the groove 411 can position the cable 200, so that the cable 200 can be fixed at the same position between the first clamping member 41 and the second clamping member 42. Furthermore, the opening of the groove 411 can compress the cable 200, so that the cable 200 can be firmly pressed between the first clamping member 41 and the second clamping member 42. In addition, by making the inner diameter of the wire groove 411 smaller than the outer diameter of the cable 200, the cable 200 can be prevented from extending too far into the wire groove 411, thereby reducing the clamping force of the first clamping member 41 and the second clamping member 42 on the cable 200.

[0081] And / or, the other of the side of the first clamping member 41 facing the second clamping member 42 and the side of the second clamping member 42 facing the first clamping member 41 defines a plurality of grooves 421 or a plurality of protrusions, so that the surface of the other can be uneven, thereby increasing the friction between the cable 200 and the clamping member, so that the cable 200 can be firmly pressed between the first clamping member 41 and the second clamping member 42.

[0082] It is understandable that the number of wire troughs 411 can be set according to actual needs, with at least one required. One wire trough 411 corresponds to one lead tube 31, that is, one wire trough 411 corresponds to one cable 200 passing through the wire hole 301.

[0083] Optionally, when there are two or more wire grooves 411, that is, when two or more cables pass through the corresponding wire holes 301 in the seal 300, one wire groove 411 corresponds to one cable 200 that passes through the wire hole 301. For example, when there are five wire grooves 411, the cables 200 that pass through the corresponding wire holes 301 are respectively accommodated in each wire groove 411. In this way, the cables 200 can be prevented from overlapping and tangling between the first clamping member 41 and the second clamping member 42.

[0084] Optionally, the inner diameter of the cable tray 411 is one-third of the outer diameter of the cable 200.

[0085] In some embodiments, the groove 421 is elongated rectangular. Of course, the shape of the groove 421 can also be set according to actual needs and is not limited to elongated rectangular shape; for example, it can be semi-cylindrical.

[0086] like Figure 1 As shown, in some embodiments, the cable pulling mechanism 40 further includes a fastener 43, which is connected to the first clamping member 41 and the second clamping member 42 respectively. The fastener 43 is used to tighten or loosen the first clamping member 41 and the second clamping member 42. By tightening the first clamping member 41 and the second clamping member 42 with the fastener 43, the first clamping member 41 and the second clamping member 42 can be kept in a state of clamping the cable 200; by loosening the first clamping member 41 and the second clamping member 42 with the fastener 43, the first clamping member 41 and the second clamping member 42 can be moved away from each other and the cable 200 can be released.

[0087] In some embodiments, the fastener 43 may be a screw, which is threadedly connected to the first clamping member 41 and the second clamping member 42.

[0088] In some embodiments, the wire pulling mechanism 40 further includes a clamping connector 44, which is slidably connected to the platform 10, and a first clamping member 41 is connected to the clamping connector 44.

[0089] In some embodiments, the cable threading device 100 further includes a length measuring structure 60, which is disposed on the other side of the mounting base 20. The length measuring structure 60 is used to measure the length of the cable 200 extending out of the cable through the cable hole 301. By providing the length measuring structure 60, the length of the cable 200 extending out of the cable through the cable hole 301 can be measured. Thus, the cable 200 can be pulled out of the cable through the cable hole 301 to the required length based on the measurement result of the length measuring structure 60, resulting in better consistency in the pulling of the cable 200 each time.

[0090] In some embodiments, the length measuring structure 60 is a scale, with the zero end of the scale abutting against the mounting base 20.

[0091] In some other embodiments, the length measuring structure 60 may also be other structures for measuring length. For example, the length measuring structure 60 may be a scale marked on the platform 10, or the length measuring structure 60 may be an infrared rangefinder. The infrared rangefinder is disposed on the wire pulling mechanism 40 and is used to emit infrared rays toward the mounting base 20 and measure the displacement of the wire pulling mechanism 40, so that the length of the cable 200 passing through the wire hole 301 can be calculated.

[0092] like Figure 1 As shown, in some embodiments, the threading device 100 further includes a first guide mechanism 70 and a second guide mechanism 80, which are respectively connected to the platform 10. The first guide mechanism 70 is located on one side of the mounting base 20, and the second guide mechanism 80 is located on the other side of the mounting base 20.

[0093] The first guide mechanism 70 includes a first guide rail 71 and a first slider 72. The first guide rail 71 is connected to the platform 10, and the first slider 72 is slidably connected to the first guide rail 71. The tube connector 32 is connected to the first slider 72. Thus, the tube connector 32 can move toward or away from the mounting base 20 along the first guide rail 71 via the first slider 72.

[0094] The second guide mechanism 80 includes a second guide rail 81 and a second slider 82. The second guide rail 81 is connected to the platform 10, and the second slider 82 is slidably connected to the second guide rail 81. A clamping connector 44 is connected to the second slider 82, so that the clamping connector 44 can move along the second guide rail 81 toward or away from the mounting base 20 via the second slider 82.

[0095] Optionally, the length directions of the first guide rail 71, the second guide rail 81, and the lead tube 31 are parallel to each other; the length direction of the slide rail 511 is perpendicular to the length direction of the first guide rail 71; the length direction of the pin 514 is perpendicular to the length direction of the slide rail 511; and the length direction of the scale and the length direction of the second guide rail 81 are parallel to each other.

[0096] Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this utility model. Furthermore, embodiments of this utility model and features thereof can be combined with each other, unless otherwise specified.
