Embodiment 1

[0048] See Figure 1 to Figure 3 , The pre-branch cable of the present invention includes a trunk line cable 10, branch cables and connecting joints. The connecting joint includes a conductor connecting fitting 1 , a fitting insulating layer 2 , a fitting shielding layer 3 and a fitting sheathing layer 4 . There are two branch cables, and the two branch cables are respectively called the first branch cable 10a and the second branch cable 10b. The first branch cable 10a and the second branch cable 10b are fixedly connected and electrically connected to the trunk line cable 10 through the connection joint.

[0049] The trunk line cable 10, the first branch cable 10a and the second branch cable 10b have the same structure, and all include a cable conductor 10-1, a cable insulation layer 10-2, a cable shielding layer 10-3 and a cable sheathing layer 10-4. The cross-sectional area of ​​the cable conductor 10 - 1 of the first branch cable 10 a and the second branch cable 10 b is s...

Embodiment 2

[0065] See Figure 4 , the rest of this embodiment is the same as that of Embodiment 1, the difference is that: the main line connection part 11, the first branch connection part 12 and the second branch connection part 13 of the conductor connection fittings are arranged in a T shape in the same plane, The first branch connection part 12 and the second branch connection part 13 are arranged in a straight line, that is, the angle α at the intersection of one end of the first branch connection part 12 and the second branch connection part 13 is 180 degrees, and the main line connection part 11 is vertical It is arranged on the middle part of the first branch connection part 12 and the second branch connection part 13 .

Embodiment 3

[0067] See Figure 5 to Figure 9 , the rest of this embodiment is the same as Embodiment 1, the difference is that it also includes a third branch cable, the structure of the third branch cable is the same as that of the first branch cable 10a and the second branch cable 10b, and the third branch cable The sectional area of ​​the cable conductor 10-1 of the cable is equal to the sectional area of ​​the cable conductor 10-1 of the first branch cable 10a.

[0068]The conductor connecting hardware further includes a third branch connecting portion 14 . One end of the first branch connecting portion 12 , the second branch connecting portion 13 and the third branch connecting portion 14 are connected, and the other ends are arranged parallel to each other. The first branch connecting portion 12 , the second branch connecting portion 13 and the third branch connecting portion 14 are distributed in an equilateral triangle. The main line connecting portion 11 is disposed at the inte...

Abstract

The invention discloses a pre-branched cable which is characterized by comprising a trunk cable, branch cables and a connecting joint. The trunk cable and the branch cables are the same in structure and each comprise a cable conductor, a cable insulating layer, a cable shielding layer and a cable sheath layer. The cross-sectional area of the cable conductor of each branch cable is smaller than that of the cable conductor of the trunk cable. The connecting joint comprises a conductor connecting fitting, a fitting insulating layer, a fitting shielding layer and a fitting sheath layer. The numberof the branch cables is two or three, and each branch cable is fixedly and electrically connected with the trunk cable through the connecting joint. The fitting insulating layer of the connecting joint is connected with the cable insulating layer of each cable into a whole. The fitting shielding layer of the connecting joint is overlapped with the cable shielding layer of each cable in a coveringmanner. The fitting sheath layer of the connecting joint is connected with the cable sheath layer of each cable into a whole.

Description

technical field [0001] The invention belongs to the technical field of power cables, and in particular relates to a pre-branched cable used on ships and a manufacturing method thereof. Background technique [0002] As an important component of information and power energy transmission, power cables are widely used in various industries. Due to the limited space of the ship, and considering the light weight of the ship, the laying of the lines on the ship is also more important. As the development of ships tends to be more functional and integrated, the application of power cables in ships also tends to be diversified. The original laying method usually directly lays the corresponding lines from the power supply to each device. This kind of laying method has a large number of lines, a large amount of laying work, and more troublesome laying. It not only takes up space but also increases the weight of the ship. In consideration of saving space and weight, pre-branch cables a...
