Problems solved by technology

However, at present, the metal conductors in the butt joints, lead joints and other joints of the connecting members are separate from the external insulator, and there are the following problems when connecting: (1) The connection between the conductor part and the external insulating part needs to be carried out one by one. It is cumbersome; (2) The power must be cut off when connecting, and it cannot be connected with electricity, which will affect the reliability of power supply and cause economic losses

Embodiment 1

[0021] Embodiment 1. This embodiment is applied to a live connection member of a European-style cable branch box that only needs to connect one branch wire. Such as figure 1 As shown, the connector includes a butt joint 1 , a lead joint 2 and a sealing joint 3 arranged in sequence, and the outer end of the butt joint 1 is screwed to the butt sleeve 4 . The butt joint 1 includes a butt joint connecting conductor 11 and a butt joint hard insulating sheath 12 integrated therewith. The inner conductor 11 of the butt joint is an integral part of the front section screw and the back section helical tube with opposite screw threads at both ends. The outer diameter of the screw tube section is larger than the outer diameter of the screw section, and the outer wall has an outwardly protruding positioning ring. The hard insulating sleeve 12 of the butt joint is tapered conical, the front section of which is a conical arc extinguishing chamber 13, and the rear section has an axial centr...

Embodiment 2

[0024] Embodiment 2, this embodiment is applied to the live connection member of the European-style cable branch box that needs to connect two branch wires. Such as figure 2 As shown, this embodiment includes a butt joint 1 , a lead joint 2 , an extension joint 6 , a lead joint 2 and a sealing joint 3 arranged in sequence, and the outer end of the first butt joint 1 is screwed to the butt sleeve 4 .

[0025] The continuous joint 6 comprises a continuous joint connection conductor 61 and a continuous joint hard insulating sleeve 62 integrated therewith. The continuous joint hard insulating sleeve 62 is a tapered conical shape, and there is an axial center through hole in it, and its length is less than its length. The length of the inner continuous joint connection conductor 61, the screw rod and the helical tube front portion of the continuous joint connection conductor 61 stretch out outside the hard insulating sleeve 62 of the joint joint. The middle section of the outer w...

Embodiment 3

[0028] Embodiment three, such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the connecting conductor 11 of the butt joint is a double-ended screw with opposite screw threads at both ends, and the middle section is a cylindrical section whose outer diameter is larger than the outer diameter of the screw, and the outer wall of the cylindrical section has Convex retaining ring. Both ends of the rigid insulating sleeve 12 of the butt joint are tapered arc extinguishing chambers 13 . The butt joint connection conductor 11 has a cylindrical section corresponding to the middle section of the butt joint hard insulating sleeve 12 , and the screw rods at both ends respectively extend into the corresponding conical arc extinguishing chamber 13 and are embedded in the axial center of the butt joint hard insulating sleeve 12 . The connecting conductor 21 of the lead joint is an internally threaded tube that matches the inner double-ended screw of th...

Abstract

The present invention discloses an electric connection / lap joint component of a European-style cable branch box. The component comprises at least one butt joint and lead connector, a plurality of splicing connectors and a sealing connector, wherein the butt joint, the lead connector and the sealing connector are connected in turn to form a branch connection / lap joint component or adjacent lead connectors are connected through the splicing connectors and the butt joint, and a front end of the first lead connector is connected with the butt joint while a rear end of the last lead connector is connected with the sealing connector to form a multiple branch connection / lap joint component; each connector and joint is an integrated part composed of an internal conductor and an external hard insulating bush, a connection end of the internal conductor of each connector and joint is in a threaded connection structure, and connection points of the butt joint / lead connector and the conductors are all at arc extinguishing chambers of the hard insulating bushes. After the connectors and joint are connected, the internal conductors are integrated, the external hard insulating bushes are sealed, and operators contact the hard insulating bushes during splicing. Continuous expansion of a plurality of splicing connectors and lead connectors can be realized.

Description

technical field [0001] The invention relates to a European-style cable branch box connector, in particular to a European-style cable branch box live connection component. Background technique [0002] The current European-style cable branch box uses the wall bushing as the connecting busbar, and then realizes cable branching or transfer through the connecting member connected with the wall bushing. However, at present, the metal conductors in the butt joints, lead joints and other joints of the connecting members are separate from the external insulator, and there are the following problems when connecting: (1) The connection between the conductor part and the external insulating part needs to be carried out one by one. It is cumbersome; (2) When connecting, the power must be cut off, and the live connection cannot be made, which will affect the reliability of power supply and cause economic losses. Contents of the invention [0003] The object of the present invention is...
