[0002] Cables are mainly used in power transmission, information communication and industrial fields. Power cables are the core products, used to transmit and distribute high-power electrical energy. They are mainly laid in urban underground power grids, power plant lead-out lines and other scenarios to ensure the stability and security of power supply. Communication cables and optical fibers are used to transmit signals and data, supporting information transmission systems such as the Internet and communication networks, and realizing the efficient transmission of data and voice signals.

[0003] When the waterproof cable port in this patent is connected to other cables, the stability of the connection is poor because different cables have different diameters, while the inner diameter of the port is mostly fixed during production.

[0004] To address the aforementioned technical issues, CN222996219U discloses a waterproof cable at the end, which clamps and fixes cables of different diameters by means of the contraction or expansion of the clamping claws. This not only improves the assembly accuracy but also ensures the firmness and sealing of the cable connection. In addition, it can reduce the mechanical stress concentration caused by the difference in cable diameter, further improving the durability and reliability of the overall system.

[0005] The above-mentioned existing technologies also have the following shortcomings: in actual use, the waterproofing methods of the above technologies are relatively complex and cumbersome, making them unsuitable for practical applications, and water seepage is prone to occur at the top.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a cable with waterproof ends, including a cable body 1:

[0026] One end of the cable body 1 is provided with a connecting component 3 for power connection. Both the cable body 1 and the connecting component 3 are provided with a series connection mechanism 2 for sealing. One end of the connecting component 3 is provided with a terminal connection mechanism 4 for external power connection.

[0027] The connecting component 3 includes a sleeve component disposed on the outside of the cable body 1, and a sealing component is provided at one end of the sleeve component;

[0028] The end connection mechanism 4 includes a power supply component disposed at one end of the connecting component 3, and an external component is disposed at one end of the power supply component.

[0029] Preferred:

[0030] like Figure 2 As shown, the socket assembly includes a sealing ring 21 fixedly installed on one end of the outer side of the cable body 1 and an outer sleeve 22 in close contact with the sealing ring 21. The sealing ring 21 is provided for limiting the connection and assisting in sealing after the outer sleeve 22 is connected. The sealing ring 21 can be made of rubber.

[0031] further:

[0032] like Figure 2As shown, the sealing assembly includes an inner sleeve 24 threadedly connected to the inside of the outer sleeve 22. A first annular sealing ring 23 is installed at one end of the inner wall of the inner sleeve 24, and a second annular sealing ring 25 is installed at the other end of the inner wall of the inner sleeve 24. The inner sleeve 24 is mainly used to fit the inner sleeve 24 and form a sealed waterproof operation. The first annular sealing ring 23 and the second annular sealing ring 25 can effectively seal the connection between the two ends of the inner sleeve 24 and improve the waterproof performance.

[0033] It is worth noting that:

[0034] like Figure 3 As shown, the connecting component 3 includes a copper lug crimp connector 31 that is crimped onto the outer surface of one end of the cable body 1. One end of the outer surface of the copper lug crimp connector 31 is provided with a first annular groove 32 that is adapted to the first annular sealing ring 23. The copper lug crimp connector 31 is used to be crimped and fixed by crimping pliers, which facilitates the subsequent connection of the energized components. The first annular groove 32 is mainly used to adapt to the first annular sealing ring 23 to form a sealed and waterproof effect.

[0035] in addition:

[0036] like Figure 4 As shown, the power-conducting assembly includes an internally threaded connector 41 fixedly installed at one end of the copper nose crimp connector 31. The internal thread of the internally threaded connector 41 is connected to an externally threaded connector 42. The internally threaded connector 41 is designed to facilitate the threaded connection of the externally threaded connector 42, while the externally threaded connector 42 is used for support and conduction to the outer ring 43 of the copper nose.

[0037] at last:

[0038] like Figure 4 As shown, the external assembly includes a copper lug outer ring 43 fixedly installed at one end of the external threaded connector 42 and a second annular groove 44 opened on the outside of the copper lug outer ring 43. The second annular groove 44 is adapted to the second annular sealing ring 25. The copper lug outer ring 43 can be bolted and fixed to the equipment at the required end after the above operation. The second annular groove 44 is opened to adapt to the second annular sealing ring 25 to ensure its required sealing and waterproof performance.

[0039] During operation, first, the outer sleeve 22 is fitted from the other end, and then it is slid on the outside of the cable body 1 until it moves to the position corresponding to the end of the cable body 1 and then stops moving. At this time, the sealing ring 21 will be fitted inside it, and the two can be tightly connected. When operating the above steps, the copper lug crimp connector 31 can be pre-installed. After fitting the copper lug crimp connector 31 onto the end of the required cable body 1, it is crimped by pressure clamps. The state after crimping is as shown in the figure. Its top and bottom surfaces are concave to facilitate a tight connection with the cable. After crimping is completed, the sealing operation of the end can be prepared.

[0040] During sealing, the inner sleeve 24 is removed and moved from the copper lug crimp connector 31 and fitted onto its outside. Then, it is aligned with the outer sleeve 22 and rotated synchronously to form a threaded connection between them. The continuous connection will cause the two ends to tighten in opposite directions and tightly clamp the sealing ring 21 between them, thereby forming a waterproof operation at one end of the cable. The first annular sealing ring 23 and the second annular sealing ring 25 set at both ends of the inner sleeve 24 are in the preset position and are adapted to the first annular groove 32 and the second annular groove 44 to complete the sealing operation.

[0041] Finally, remove the copper lug outer ring 43 to align the external threaded connector 42 with the internal threaded connector 41. Then, extend the external threaded connector 42 into the interior of the internal threaded connector 41 and tighten it to complete the subsequent power-conducting operation. Simply bolt the fixed copper lug outer ring 43 to the external power supply equipment.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
