Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0057] figure 1 It is a flow chart of a method for making a cable branch joint provided by an embodiment of the present invention, such as figure 1 As shown, the production method includes:

[0058] S111: Stripping the ends of the main cable and sub-cable to be connected.

[0059] So that the shielding layer, wrapping, insulation layer and wire core of the main cable and sub-cables are exposed to the outer sheath, and there are at least two sub-cables.

[0060]S112: Set the inner layer heat shrinkable tube, the copper braided net sleeve and the outer layer heat shrinkable tube on the main cable.

[0061] S113: Use copper tubes to connect the cores of the main cable and the cores of the sub-cables.

[0062] Wherein, the wire core of...

Abstract

The invention discloses a method for manufacturing a cable branch joint, belonging to the field of electrical engineering. The production method comprises the steps of stripping end parts of a main cable and a branch cable to be connected, sleeving an inner layer heat shrinkable tube, a copper woven net sleeve and an outer layer heat shrinkable tube in the main cable, using a copper tube to connect a wire core of the main cable and a wire core of the branch cable, orderly winding an insulation self-adhesive tape, a Teflon film, a cable filling tape and a sealing tape on the copper tube, moving the inner layer heat shrinkable tube, heating the inner layer heat shrinkable tube such that the inner layer heat shrinkable tube shrinks, moving the copper woven net sleeve, fastening the copper woven net sleeve, moving the outer layer heat shrinkable tube, and heating the outer layer heat shrinkable tube such that the outer layer heat shrinkable tube shrinks. Thus the connection part of the main cable and the branch cable is protected, the security is improved further, the manufacture is convenient, the size of the branch joint is small, the installation is convenient, the security is high, and the method is especially suitable for manufacturing branch joints of 1KV to 10KV high voltage cables.

Description

technical field [0001] The invention relates to the field of electrical engineering, in particular to a method for manufacturing a cable branch joint. Background technique [0002] Cables are mainly used to transmit electricity. During the cable layout process, there will be more branches to transmit power to different electrical appliances. [0003] At present, the branch of the cable is mainly connected through a junction box or a branch joint. When connecting through a junction box, the main cable is connected to the junction box, and the sub-cables are connected to multiple joints on the junction box one by one, so that the main cable Indirect connection with sub-cable. The branch joint is to directly connect the end of the main cable with multiple sub-cables through copper pipes. Although the connection of the branch joint is low in cost, occupies a small space, and is convenient for on-site production, the existing branch joints are relatively low in safety. There a...
