Description

Technical Field

[0001] This utility model relates to the field of watertight cable technology, specifically a composite watertight cable. Background Technology

[0002] Composite watertight cables are cables with waterproof, moisture-proof, and corrosion-resistant properties. Watertight cables are manufactured according to specific designs and processes to ensure that they can maintain good electrical performance in humid or underwater environments. They are mainly divided into two types: transverse watertight cables and longitudinal watertight cables.

[0003] Existing composite watertight cables, such as the network cable composite watertight cable disclosed in publication number CN222260581U, have the advantages of preventing the protective layer from being broken by local hard compression and having buffering performance. However, the cable core inside this composite watertight cable is waterproofed by a single layer of hydraulic gel material arranged on the outer layer, which makes its waterproof performance poor. Therefore, we propose a composite watertight cable. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0007] Preferably, the outer ends of the electrical units are also wrapped with a second water-blocking tape.

[0008] Preferably, the inner end of the waterproof frame is also provided with clamping frames, and the clamping frames are located at the outer end of the optical unit.

[0009] Preferably, the outer end of the waterproof frame is further provided with an inner sheath, and the space between the inner sheath and the waterproof frame is filled with water-resistant grease.

[0011] Preferably, the outer layer of the armor layer is further fixedly provided with an outer protective sleeve.

[0012] Preferably, filler strips are also arranged and installed at the outer end of the waterproof frame.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, the waterproof frame installed at the outer end of the optical unit and electrical unit inside the cable body can separate the optical unit and electrical unit from the inner sheath at the outer end. Then, through the water-blocking powder filled at the inner end of the waterproof frame and the water-blocking grease filled between the outer end of the waterproof frame and the inner sheath, a double water-blocking effect is formed on the optical unit and electrical unit inside the cable body. Combined with the first water-blocking tape and the second water-blocking tape directly wrapped around the outer end of the optical unit and electrical unit, multiple water-blocking effects can be formed on the optical unit and electrical unit inside the cable body, thereby improving its watertight effect during use.

[0015] 2.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a composite watertight cable. Example 1

[0023] Combination Figure 1-3As shown, the present invention provides a composite watertight cable, comprising: a cable body 100; the cable body 100 includes a waterproof frame 101 disposed at its inner end, an optical unit 102 installed in the middle of the waterproof frame 101, electrical units 103 installed at each of the four corners of the waterproof frame 101, a first water-blocking tape 104 wrapped and fixed to the outer end of the optical unit 102, an inner water-blocking powder 105 filled at the inner end of the waterproof frame 101, a thickened portion 106 disposed at each of the four corners of the outer end of the waterproof frame 101, a slot 107 opened in each of the thickened portion 106, and an outer water-blocking powder 108 filled in each of the slots 107; the outer ends of the electrical units 103 are also wrapped with... The waterproof frame 101 is fixed with a second water-blocking strip 109. The inner end of the waterproof frame 101 is also fixedly provided with clamping frames 110, which are located at the outer end of the optical unit 102. The outer end of the waterproof frame 101 is also provided with an inner sheath 111. Water-blocking grease 112 is filled between the inner sheath 111 and the waterproof frame 101. An armor layer 113 is fixedly provided on the outer layer of the inner sheath 111. An outer sheath 114 is fixedly provided on the outer layer of the armor layer 113. Filler strips 115 are also arranged and installed on the outer end of the waterproof frame 101. The waterproof frame 101 is made of rubber. The outer ends of the optical unit 102 and the electrical unit 103 are both provided with a shielding layer and an insulating layer.

[0024] Specifically, the composite watertight cable is a cable with waterproof, moisture-proof, and corrosion-resistant properties. The waterproof frame 101 installed at the outer end of the optical unit 102 and electrical unit 103 within the cable body 100 separates the optical unit 102 and electrical unit 103 from the inner sheath 111 at the outer end. Furthermore, the inner water-blocking powder 105 filled at the inner end of the waterproof frame 101, and the water-blocking grease 112 filled between the outer end of the waterproof frame 101 and the inner sheath 111, form a double water-blocking effect on the optical unit 102 and electrical unit 103 within the cable body 100. This, combined with the first water-blocking tape 104 and the second water-blocking tape 105 directly wound around the outer ends of the optical unit 102 and electrical unit 103, further enhances the water-blocking effect. 09, can form multiple water-blocking elements for the optical unit 102 and electrical unit 103 inside the cable body 100, thereby improving its watertightness during use. At the same time, the thickened part 106 provided on the outside of the electrical unit 103 at the four ends of the waterproof frame 101 can also enhance the waterproofness of the part of the electrical unit 103 that is close to the outer wall of the cable body 100 by filling the outer water-blocking powder 108 in its inner groove 107. The clamping frame 110 arranged at the inner end of the waterproof frame 101 is mainly used for the installation and support of the optical unit 102. The inner sheath 111, armor layer 113 and outer sheath 114 at the outer end of the cable body 100 are mainly for the outer end protection of the cable body 100.

[0025] Working principle and usage process of this utility model:

[0026] When water penetrates the inner sheath 111 at the inner end of the cable body 100, the water-blocking grease 112 filled between the inner sheath 111 and the waterproof frame 101 can first perform water-blocking sealing on the outer layer of the optical unit 102 and the electrical unit 103. Meanwhile, the inner water-blocking powder 105 filled to the outside of the optical unit 102 and the electrical unit 103 at the inner end of the waterproof frame 101 will perform water-blocking sealing on the middle layer of the optical unit 102 and the electrical unit 103. At the same time, the first water-blocking tape 104 and the second water-blocking tape 109 wrapped around the outside of the optical unit 102 and the electrical unit 103 will perform water-blocking sealing on the inner layer of the optical unit 102 and the electrical unit 103. Thus, through multiple layers of protection, water penetration into the optical unit 102 and the electrical unit 103 is prevented. At the same time, the slot 107 opened in the waterproof frame 101 on the outside of the electrical unit 103 can also perform water-blocking protection on the weak part near the outer wall of the cable body 100 through the outer water-blocking powder 108 filled at its inner end.

[0027] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
