Description

Technical Field

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

[0002] When cables are used, they are cut to the required length, leaving one end exposed. If the exposed cable end is exposed to the air for a long time, air will enter the cable conductor. The conductor is usually made of metal conductors such as copper. Water vapor in the air can easily cause the conductor inside the cable to oxidize and turn black, which will lead to rust and cause safety hazards during later operations.

[0003] To prevent exposed cable ends from contacting air, those skilled in the art have implemented a method of assembling protective sleeves at the cable ends to isolate them from air. The protective sleeve is an elastic rubber sleeve that, when fitted over the exposed cable end, allows its inner wall to fit tightly against the cable's outer sheath due to friction. The inner bottom wall of the sleeve covers the cable conductor, making it difficult for air to contact the conductor and thus protecting the exposed cable end. However, currently, assembling protective sleeves at exposed cable ends still relies on manual labor, resulting in low assembly efficiency. Therefore, a cable end sealing device is urgently needed to address these technical problems. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a cable end sealing device to improve the above-mentioned problems.

[0005] This utility model provides a cable end sealing device for mounting a protective sleeve on a cable. It includes an expansion device and a pushing device. The expansion device comprises an expansion claw driving device and multiple expansion claws. When all the expansion claws converge, the protective sleeve is fitted onto the expansion claws in a reverse direction. The expansion claw driving device drives the expansion claws to expand and stretch the protective sleeve. The expansion claw driving device includes a base with a groove. A slider is provided at the bottom of each expansion claw. The slider slides within the groove, causing the expansion claws to converge or expand on the base. The pushing device drives the expansion claws to fit the protective sleeve onto the cable.

[0006] Furthermore, the groove is a straight groove.

[0007] Furthermore, the groove is a curved groove.

[0008] Furthermore, the expansion claw driving device also includes a turntable and multiple connecting rods. One end of all the connecting rods is hinged to the turntable, and the other end of each connecting rod is hinged to the slider. The turntable drives the connecting rods to drive the expansion claw to converge or expand on the base.

[0009] Furthermore, the turntable is driven by a motor device that switches the turntable between forward and reverse rotation.

[0010] Furthermore, the motor device includes a motor and a gearbox. The output end of the motor is connected to the input end of the gearbox, and the output end of the gearbox is connected to the turntable. The turntable is driven to rotate forward or backward by the commutation of the motor.

[0011] Furthermore, the motor device is a servo motor or a stepper motor.

[0012] Furthermore, the motor device is connected to the telescopic end of the pushing device.

[0013] Furthermore, the pushing device drives the expanding device to perform reciprocating linear motion.

[0014] This utility model provides the following beneficial effects: A cable end sealing device includes an expansion device and a pushing device. The expansion device includes an expansion claw driving device and multiple expansion claws. When all the expansion claws converge, a protective sleeve is fitted onto them in reverse, with the inner bottom wall of the protective sleeve facing outwards. The expansion claw driving device drives the expansion claws to expand and stretch the protective sleeve. The stretching range is determined according to the diameter of the cable to be assembled, such that the expansion claws expand to a diameter slightly larger than the diameter of the exposed cable end. Then, the pushing device drives the expansion claws to move towards the cable end, causing the inner bottom wall of the protective sleeve to contact the cable end. The pushing device further drives the pushing device to flip the side wall of the protective sleeve over the cable end, thereby fitting the protective sleeve onto the cable. Finally, the pushing device resets.

[0015] When assembling protective sleeves using the cable end sealing device of this utility model, workers only need to hold the cable end sealing device to automatically complete the installation of the cable protective sleeve, which greatly improves the assembly efficiency of the protective sleeve. At the same time, since the protective sleeve of this solution is expanded as a whole by the expansion claw, it also avoids damage to the protective sleeve during manual assembly and improves the quality of exposed assembly.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Example 1:

[0031] like Figure 1 This embodiment discloses a cable end sealing device for mounting a protective sleeve on a cable. For example, after a cable or wire is cut, its internal metal conductor will be exposed. The cable end sealing device of this embodiment is used to mount a protective sleeve on the exposed end of the cable or wire.

[0032] The cable end sealing device includes a housing 10, within which a pushing device is provided. The pushing device is used to push an expansion device 20, which is used to place and expand the protective sleeve. The expansion device includes an expansion claw drive device 22 and multiple expansion claws 21. When all the expansion claws 21 are brought together, the protective sleeve is reversed and fitted onto the expansion claws 21. The expansion claw drive device 22 drives the expansion claws 21 to expand and stretch the protective sleeve.

[0033] like Figures 2-7 The expansion claw drive device 22 includes a base 221 with a groove 222, and a slider 211 is provided at the bottom of the expansion claw 21. The expansion claw 21 is brought together or expanded on the base 221 by sliding the slider 211 in the groove 222.

[0034] The expansion claw 21 and the slider 211 can be fixedly connected in an integrated design or other ways.

[0035] The pusher 11 drives the expansion claw 21 to put the protective sleeve onto the cable.

[0036] The process of assembling the protective sleeve of the aforementioned cable end sealing device is as follows: When the expansion claw 21 converges, the protective sleeve is fitted onto the expansion claw 21 in reverse, with the inner bottom wall of the protective sleeve facing outward. The expansion claw driving device 22 drives the expansion claw 21 to expand and stretch the protective sleeve. The stretching range is determined according to the diameter of the cable to be assembled, so that the expansion claw expands to a diameter slightly larger than the diameter of the exposed end of the cable. Then, the pushing device drives the expansion claw 21 to move towards the cable end, so that the inner bottom wall of the protective sleeve contacts the cable end. The pushing device is further driven to flip the side wall of the protective sleeve over the cable end, thereby fitting the protective sleeve onto the cable. Then, the pushing device is reset.

[0037] Therefore, when assembling the protective sleeve using the cable end sealing device of this utility model, the worker only needs to hold the cable end sealing device by hand, which greatly improves the assembly efficiency of the protective sleeve. At the same time, since the protective sleeve of this solution is expanded as a whole by the expansion claw 21, it also avoids damage to the protective sleeve during manual assembly and improves the quality of exposed assembly.

[0038] like Figure 2 - Unlike 6, groove 222 is a straight groove. For example... Figure 7Furthermore, the groove 222 is a curved groove, which can reduce the reaction force of the groove 222 on the slider 211 during the sliding process.

[0039] like Figures 2-7 Furthermore, the expansion claw drive device 22 also includes a turntable 223 and multiple connecting rods 224. One end of each connecting rod 224 is hinged to the turntable 223, and the other end of each connecting rod 224 is hinged to the slider 211. The turntable 223 drives the connecting rods 224 to drive the expansion claws 21 to converge or expand on the base 221. The turntable 223 rotates at an angle, simultaneously driving the connecting rods 224. The connecting rods 224 drive the slider 211 to move within the slide groove 222, thereby driving the expansion claws 21 to move. Multiple expansion claws 21 move along the slide groove 222 to form the expansion claws 21 converging or expanding on the base.

[0040] like Figures 2-7 Furthermore, each connecting rod 224 has a support post 225 at its hinge point with the turntable 223. The hinge structure between one end of the connecting rod 224 and the turntable 223 is as follows: one end of the connecting rod 224 is connected to the turntable 223 via the support post 225, and the support post 225 has a bearing. The other end of the connecting rod 224 is hinged to the slider 211, which is a cylindrical body, and a bearing is located between the slider 211 and the groove 222. Preferably, the bearing is located on the slider 211 and slides together with the slider 211 within the groove 222, and the bearing is used to reduce sliding friction. Preferably, the bearing is one of a sliding bearing, a rolling bearing, or a spherical bearing.

[0041] like Figure 8 The base 221 is provided with a rear cover 226, which is located on the side of the base 221 away from the slide groove 222. The expansion claw drive device 22 is located in the cavity surrounded by the rear cover 226 and the base 221.

[0042] Furthermore, the turntable 223 is driven by a motor that switches between forward and reverse rotation. When the motor rotates in one direction, the expanding claws 21 converge on the base 221; when the motor rotates in the opposite direction, the expanding claws 21 expand on the base 221. The motor is located inside the motor housing 30.

[0043] The rear cover 226 is fixedly connected to the motor housing 30, such as by welding or other connection methods.

[0044] Furthermore, the motor assembly includes a motor and a gearbox. The output end of the motor is connected to the input end of the gearbox, and the output end of the gearbox is connected to the turntable 223. The turntable 223 is driven to rotate forward or backward by the commutation of the motor. Since the diameter range of cables on the market is large and the protective sheath is elastic, when the elastic reaction force is large when the protective sheath expands, adding a gearbox to the output end of the motor can increase the output torque to withstand the large elastic force of the protective sheath.

[0045] Furthermore, in the cable end sealing device of this embodiment, the motor device in the expansion device 20 used to drive the turntable 223 can be a servo motor or a stepper motor. Both types of motors can be reversed, and directly using the above-mentioned motor and turntable 223 can improve the portability of the cable end sealing device.

[0046] Furthermore, the motor device in the expansion device 20 used to drive the turntable 223 is connected to the telescopic end of the push device, for example, the motor device is connected to the telescopic end of the push device through a flange.

[0047] Furthermore, the driving device drives the expansion device 20 to perform reciprocating linear motion. In this embodiment, the cable end sealing device is preferably battery powered, and the driving device can be an electro-hydraulic rod, an electric push rod, or other device that converts electrical energy into linear motion. Of course, the driving device can also be a pneumatic push rod, etc.

[0048] like Figure 8 Furthermore, the outer casing 10 is provided with a first handle 11 and a second handle 12, one for holding and the other for assisting holding. Single-person single-handed operation can be achieved through the first handle 11 and the second handle 12.

[0049] Furthermore, a power socket is provided inside the housing 10, or the housing contains a battery, and the cable end sealing device is powered by the battery, which can be a solid-state battery.

[0050] It should be noted that the housing 10 is provided with a forward rotation switch and a reverse rotation switch for starting the motor device; the housing 10 is also provided with a forward start switch and a reverse start switch for the push device.

[0051] The method of using the cable end sealing device in this embodiment is as follows: ① Determine the stretching range according to the diameter of the cable to which the protective sleeve needs to be installed. Place the protective sleeve onto the expansion claw 21 of the expansion device 20 in reverse. The motor rotates forward to drive the expansion claw 21 to expand until its diameter is slightly larger than the cable end. ② Align the expansion device 20 with the cable end and turn on the forward start switch of the pushing device. The expansion claw 21 automatically moves forward under the action of the pushing device, flipping the protective sleeve over the cable end. ③ After the protective sleeve is installed, turn on the reverse start switch of the pushing device. The expansion device 20 retracts as a whole, and the motor rotates in reverse to drive the expansion claw 21 to converge to its initial state, completing the installation of the protective sleeve.

[0052] Furthermore, in the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
