A kind of harness cable connection connecting terminal block
Technical field
The present invention relates to electrical equipment, specifically a kind of harness cable connects connecting terminal block.
Background technique
Connecting terminal be for convenience conducting wire connection and apply, it in fact be exactly one section be enclosed in inside ambroin
Sheet metal, both ends have hole that conducting wire can be inserted, and have screw to be used to fasten or unclamp, such as two conducting wires, it is sometimes desirable to even
It connects, needs to disconnect again sometimes, at this moment they can be connected with terminal, and can disconnect at any time, without it
Weld or be intertwined, it is convenient and efficient.Connecting terminal block is one kind of connecting terminal, simultaneously by single terminal stud
It is unified into multiple terminal studs.
But the connecting terminal block of existing market can have the following problems in use, the existing connecting terminal block of a.
It is all to be fixed using single-point in the fixation to conducting wire, so that the locking point of conducting wire is only limitted at conductor grip, when conducting wire is by external force
Effect, active force are all centered at the junction of conducting wire and conductor grip, be easy to cause the fracture of connecting position of wires, make itself and connection
The extraneous component of chain rupture between terminal, conducting wire connection can not work, i.e. safety is lower;B. existing connecting terminal block is in parallel
When, the terminal jacks of each connecting terminal block are respectively positioned in same plane, so that the wiring difficulty of conducting wire is larger, and are tieed up in the later period
In shield, cannot every cabling visible in detail trend, i.e. practicability is lower.
