Description

Technical Field

[0001] The present invention relates to the technical field of cable shunt, and in particular to a shunt device for cables. Background Art

[0002] Connectors will encounter different environments during use, and different environments require connectors to have different performance. For example, in a humid environment, the connector tail needs to be treated with moisture-proof treatment; in a dusty environment, the connector tail needs to be sealed and dustproof; when used underwater, the connector tail needs to be sealed and water-resistant to ensure the IP level of the connector tail. Therefore, when the connector tail needs to meet the conditions of deep water work, the tail accessories need to be vulcanized. The process performance of vulcanization can meet the requirements of the connector tail to withstand 1500 meters of water pressure and 15MPa of hydrostatic pressure. The tail end of this vulcanized tail accessory will extend into a watertight cable, which transmits electrical signals from one end of the connector to the device at the tail end. When the electrical signal at the tail end requires branching transmission, it is naturally required that the cable at the tail end of the connector be branched and shunted, so there will be a problem of branching cables. At present, there is no device for branching and shunting cables, and cable branching and shunting has always been a technical problem that needs to be solved. Summary of the invention

[0003] The object of the present invention is to provide a branching device for cables to solve the problems existing in the above-mentioned prior art and facilitate branching and branching of cables.

[0004] To achieve the above object, the present invention provides the following solutions:

[0005] The present invention provides a shunt device for cables, comprising a tail nut and a branch gasket, wherein the branch gasket is located inside the tail nut and is threadedly connected to the tail nut, a slope is provided at one end of the inner wall of the tail nut, and the tail nut opens outward at the slope; at least two wire core holes are provided on the branch gasket.

[0006] Preferably, the axial direction of the wire core hole is parallel to the axial direction of the branch gasket, and the branch gasket is coaxial with the tail nut.

[0007] Preferably, a cylindrical wire core sheath is fixedly provided in each of the wire core holes.

[0008] Preferably, two positioning keys are further provided on a side of the branch gasket away from the slope.

[0009] Preferably, the positioning key is in the shape of a cuboid, and each edge of the positioning key is chamfered.

[0010] Preferably, the slope has a gradient of 15°.

[0011] Compared with the prior art, the present invention has achieved the following technical effects:

[0012] The cable shunt device of the present invention can branch and shunt cables, and is easy to use. In the cable shunt device of the present invention, the tail screw sleeve is connected to the tail attachment through a threaded connection, and then connected to the branch gasket through a threaded connection, so that the tail attachment limits the branch gasket, so that the branch gasket does not move axially. The ramp structure provided in the tail nut can prevent the shunted cable from interfering with the tail nut, and also prevent the tail nut from scalding the cable branch in a high temperature environment.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The object of the present invention is to provide a branching device for cables to solve the problems existing in the above-mentioned prior art and facilitate branching and branching of cables.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Embodiment 1

[0026] like Figures 1 to 5 As shown: This embodiment provides a branching device for cables, including a tail nut and a branch gasket 1, the branch gasket 1 is located in the tail nut and is threadedly connected to the tail nut, the tail nut sleeve 3 is connected to the tail accessory through a threaded connection, so that the tail accessory limits the branch gasket 1, so that the branch gasket 1 will not move axially; the tail nut is used to fix the branch gasket 1 to ensure that the entire tail end structure is axially fixed and no displacement is generated.

[0027] A slope 301 is provided at one end of the inner wall of the tail nut, and the tail nut opens outward at the slope 301, and the slope 301 has a slope of 15°; two wire core holes 101 are provided on the branch gasket 1, and a cylindrical wire core sheath 2 is fixed in each wire core hole 101, and the wire core sheath 2 is used to protect the insulation skin of the cable core from being damaged to ensure electrical properties. The inner wall of the wire core sheath 2 is in contact with the cable core, and when the inside of the tail accessory is filled with potting glue, it can also fill the gaps between the wire cores. Since the end of the tail accessory needs to be vulcanized, the processing temperature of the hot vulcanization process is 170℃~180℃, and temperature conduction will cause the temperature of the branch gasket 1 to rise. The high temperature environment will cause the cable core skin to be scalded, resulting in a short circuit. Adding a cable sheath can isolate the temperature transferred by the branch gasket 1 and improve the electrical performance of the product.

[0028] The axial direction of the wire core hole 101 is parallel to the axial direction of the branch gasket 1, and the branch gasket 1 is coaxial with the tail nut. Two positioning keys 102 are also provided on the side of the branch gasket 1 away from the ramp 301; the positioning key 102 is a rectangular parallelepiped, and each edge of the positioning key 102 is chamfered, so that the positioning key 102 can be more gentle when meshing with the front end structure of the tail accessory, because there is a blind insertion during meshing, and such a design can perform blind insertion more gently. The two positioning keys 102 mesh with the tail end parts to fix the position of the branch gasket 1, thereby ensuring that the position of the rear end cable is fixed and will not shake inside the tail accessory.

[0029] Reference Figure 5 When the cable shunt device of this embodiment is in use, the internal sealing glue 2060 is formed to form a sealing point 4, and one side of the tail nut is designed to be a slope 301. Since the direction of the cable is in the positive and negative directions of the Y-axis and the angle is 15°, the structure of the slope 301 is required inside the tail nut to extend the direction of the first branch 5 of the cable and the second branch 6 of the cable, to ensure that the first branch 5 of the cable and the second branch 6 of the cable do not interfere with the tail nut structure, and at the same time to ensure that the outer skin of the cable does not contact the edge of the slope 301 of the tail nut to avoid scalding the insulating outer skin in a high temperature environment.

[0030] Embodiment 2

[0031] like Figure 6 As shown, this embodiment provides a cable diverter device. Based on the first embodiment, the cable diverter device of this embodiment also has the following characteristics: three wire core holes 101 are arranged in the branch gasket 1 of the cable diverter device of this embodiment, which are used to divide the contract into three branches.
