Description

Novel cable shunting terminal

Technical Field

The utility model relates to a building distribution technical field, concretely relates to novel cable shunting terminal.

Background

With the enhancement of comprehensive national power of China, high-rise buildings and large-area plants are more and more at present, and in the design process of the power distribution system of the project, a radiation type and trunk type combined system is generally adopted for the requirements of power supply reliability and investment control. And trunk formula system is because its power consumption overlap joint is more, and traditional overlap joint mode adopts branch cable, cable T connection box, puncture fastener and cable T connection terminal etc. in advance usually, and all kinds of connected modes all have different shortcomings, wherein:

1. the puncture wire clamp has the advantages of low cost and convenience in installation, but the insulation layer and the conductor are damaged in the installation process, so that the current-carrying capacity is reduced, and the risk of electrical fire is increased; in addition, the contact reliability is poor, the resistance is large, the short-term use of the cable is caused by difficult oxidation, easy looseness and the like, and the requirement of long-term power supply reliability cannot be met.

2. Although the pre-branch cable can meet the requirement of long-term power supply reliability, the actual dimensions (the height of the shaft, the height of a layer, the position of a branch head of each layer and the like) of the building electric shaft are required to be measured before ordering, and a factory manufactures the pre-branch cable according to the actual dimensions.

3. Cable T connects case to large cross section cable, and cable T connects case to possess certain advantage, nevertheless because its structure is similar to the block terminal, needs certain installation and maintenance space, consequently has higher to the civil engineering requirement, and the cost is higher, the construction is inconvenient, consequently the acceptance level is also not high in the construction industry.

4. Compared with the connection modes, the traditional cable T-connection terminal can meet the requirement of large-scale use from cost and power supply reliability, but the traditional cable T-connection terminal adopts cable crimping, has higher requirement on the construction process, greatly improves the contact area of a trunk line and a branch line compared with a puncture wire clamp, still has smaller contact area, and has higher risk of looseness due to more connection fixing points and needs to be further optimized.

There is therefore a need for a new and new cable tap terminal that overcomes the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's defect, provide a novel cable shunting terminal.

The utility model discloses a realize like this:

the utility model provides a novel cable shunting terminal, which comprises an outer shell, be equipped with main wire casing in the shell, main wire casing is embraced into the ring form by two half slots, main wire casing is connected with intermediate junction spare, and intermediate junction spare keeps away from the one end of main wire casing and sets up a wire casing, can insert in the wire casing and establish a branch nose, and the both sides of shell correspond two half slots department and are provided with closing device.

Furthermore, a clamping screw penetrating through the branch line nose is additionally arranged outside the branch line groove.

Furthermore, the pressing device is a pressing nut which is embedded into the shell towards the semicircular groove arc section and is oppositely arranged

Further, the shell is made of an insulating material, and the insulating material is silicon rubber.

Furthermore, the main wire groove, the middle connecting piece and the branch wire groove are all made of red copper.

The utility model discloses following beneficial effect has:

1. the terminal has the advantages of reliable connection of electrical components, high power supply reliability and capability of effectively reducing faults caused by poor contact.

2. The terminal is convenient to wire, particularly simple in branch line connection, capable of being directly connected with a branch line and then connected with a main line, and capable of being used repeatedly in the later period.
