Description

A cable multi-hole connector

【Technical field】

The utility model relates to a cable connection device, in particular to a porous connector for cable branching.

【Background technique】

As is known, most of the additional wiring on the cable is to disconnect the core wire of the cable and connect the copper lugs respectively, and then crimp the other two cables on the two rings of the copper lugs, and connect the three copper lugs through the terminal block Forming a branch of the cable, this multi-point connection will not only loosen, but also easily cause poor contact; there is another way to directly wrap the stripped cable with another cable, especially when two cables of different materials are entangled together It is very easy to cause biting of the wire, and it is very easy to cause the power cable to break, reduce the original carrying capacity of the cable, and sometimes even cause short circuit and heat due to poor contact, which reduces safety and leaves a safety hazard in the long run.

【Content of invention】

In order to overcome the deficiencies in the background technology, the utility model discloses a multi-hole connector for cables, which uses copper blocks to securely connect the cables, effectively preventing ignition due to poor contact in the prior art; or damage caused by biting wires. The occurrence of cable breakage.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

A cable multi-hole connector, comprising a copper block, an insulating sleeve, an insulating plate at one end, an insulating plate at the other end, and a locking wire connecting bolt, the outer edge of the copper block is wrapped with an insulating sleeve, and the two ends of the copper block are respectively provided with an insulating plate, the other end insulating plate, the outer part of the copper block forms a fully insulating structure by the insulating sleeve, one end insulating plate, and the other end insulating plate; one end of the copper block is provided with two or three internally threaded holes that pass through the insulating plate at one end, so The other end of the copper block is provided with an internally threaded hole passing through the insulating plate at the other end; the internally threaded hole of the copper block is connected to the internally threaded hole of the copper block by a matching number of locking wire connecting bolts.

In the cable porous connector, one end of the locking wire connecting bolt is provided with a screw head with a hole, and the other end of the locking wire connecting bolt is provided with an external thread, and the connecting end of the cable is threaded on the screw with a hole. In the hole of the screw head, the connecting end of the cable is engaged by the inner raised ring in the outer thread, and at least three expansion and contraction grooves are provided at one end of the outer thread of the locking bolt.

In the cable multi-hole connector, there is at least one internally threaded hole at the other end of the copper block.

Due to the above-mentioned technical scheme, the utility model has the following beneficial effects:

The porous cable connector of the utility model uses copper blocks as the connection carrier to realize the connection of multi-strand cables; the copper blocks of the utility model make the cables firmly connected without sparking or broken strands of the cables, and can Prevent ignition due to poor contact in the prior art; or cable strand breakage due to wire biting.
