Problems solved by technology

In reality, taking the submersible pump as an example, the main cause of cable failure is that the surface of the cable and the insulating layer are easily worn during cable installation and transportation, especially when the length of the cable that comes with the submersible pump cannot meet the needs of the user. When the installation is required, an external cable is required. Since the cable cannot be fixed underwater, it will shake everywhere, and even cause the cable connection to crack and damage the sealing protection, so that the external water will extend the cable connection and directly penetrate into the copper core conductor. As a result, the waterproof function of the cable will fail, the motor will be damaged, and the pump will not operate normally.

Embodiment 1

[0029] Such as figure 1As shown, the improved environmental protection cable with high stability of the present invention includes a main cable 1 and an extension cable 2 , the stripped conductor at the connection end of the main cable 1 and the stripped conductor at the connection end of the extension cable 2 are connected to form a conductor connection part 3 . The conductor connection portion 3 of the main cable 1 and the extension cable 2 is provided with a soldering layer 4, a waterproof layer 5, an armor layer 6 and a sealing layer 7 in sequence from the inside to the outside, and the sealing layer 7 is arranged along the longitudinal direction of the conductor connection portion 3. The length is the longest, and the armor layer 7 and the sealing layer 7 cover the outermost layer of the main cable 1 , the conductor connection part 3 and the outermost layer of the extension cable 2 at the same time. The main cable 1 and the extension cable 2 located at the two ends of the...

Embodiment 2

[0031] Such as figure 2 As shown, a further improvement on the basis of Embodiment 1 is an improved environmental protection cable with high stability. The connecting rod 12 includes an outer sleeve 14 and an inner sleeve 15, and the outer wall of one end of the outer sleeve 14 is provided with external threads. Compatible with the nut 13, the outer sleeve 14 is also provided with at least three adjustment holes 16 penetrating the side pipe wall, the adjustment holes 16 are evenly distributed along the axial direction of the outer sleeve 14, and the outer wall of the mouth of one end of the inner sleeve 15 is provided with There are external threads adapted to the nut 13, and a positioning hole 17 that runs through the side pipe wall is also provided on the inner sleeve 15; the other end of the inner sleeve 15 is inserted into the outer sleeve 14, and the bolt 18 passes through the adjustment hole 16 The inner casing 15 and the outer casing 14 are fixedly connected with the p...

Embodiment 3

[0033] Such as image 3 As shown, a further improvement on Embodiment 2, an improved environment-friendly cable snap ring 8 with high stability is composed of two semi-cylinders detachably connected by connecting hinges and fastening nuts. Specifically, the snap ring 8 is composed of a detachable connection of half cylinders, one end of the half cylinder axially connected is articulated and rotatably connected by a connecting hinge 20, and the other end of the half cylinder axially connected is provided with a compression piece 21, which is threaded through a bolt. Through the through hole 22 on the compression piece 21, a nut is used to tighten and fix it.

Abstract

The invention discloses an improved environment-friendly cable with high stability. The improved environment-friendly cable comprises a main cable conductor, an extension cable conductor and a connecting rod, wherein the main cable conductor and the extension cable conductor are connected to form a conductor connection part, and the conductor connection part is sequentially provided with a soldered welding layer, a waterproof layer, an armored layer and a sealing layer from inside to outside; a main cable and an extension cable arranged on two ends of the conductor connection part are each sleeved with a cylindrical clamping ring, the inner wall of each clamping ring is provided with an elastic compressing member, the elastic compressing members are in transition fit connection with the main cable and the extension cable, the outer wall of each clamping ring is provided with at least two evenly-distributed positioning blocks in an outwardly protruded manner, a through hole is formed in each positioning block, and the axial direction of each through hole is parallel with the axial direction of the corresponding clamping ring; and two axial ends of the connecting rod pass through the through holes in the clamping rings sleeving the main cable and the extension cable, the two axial ends are fixed on the two clamping rings by means of nuts, and the length of the connecting rod between the two clamping rings is adjustable. according to the improved environment-friendly cable, cable joints are effectively fixed to prevent cracking, thereby guaranteeing normal operation of a motor.

Description

technical field [0001] The invention relates to a cable, in particular to an improved environment-friendly cable with high stability. Background technique [0002] In the construction of domestic cable projects, medium and low voltage power cables are basically laid in direct burial, through pipes or in cable trenches. During the construction process, scratches and scratches on the cable sheath often occur, and the cable protection measures for underground operations are relatively weak. In reality, taking the submersible pump as an example, the main cause of cable failure is that the surface of the cable and the insulating layer are easily worn during cable installation and transportation, especially when the length of the cable that comes with the submersible pump cannot meet the needs of the user. When the installation is required, an external cable is required. Since the cable cannot be fixed underwater, it will shake everywhere, and even cause the cable connection to c...
