To uniform and axial extension reinforcing rib, the bottom end of the reinforcing rib is arranged close to connecting pin inner end, the top of reinforcing rib
End extends into shoulder block section and is arranged close to groove.Reinforcing rib not only acts as the effect for reinforcing linkage segment structure intensity, and reinforces
Electric current conduction of the linkage section to shoulder block section, linkage section can bear heavy current impact and be hardly damaged.
In a kind of above-mentioned switch board cable copper tube, there is the inserting section outer diameter to be more than inserting for its section of body outer diameter
End is connect, the inserted terminal passes through conical surface section transition with inserting section section body outer wall.Inserted terminal is not easy to touch interference incoming end in this way,
Incoming end is facilitated to be connect with inserting section, and conical surface section has delayed electric current to climb, and improves power of resisting voltaic impingement.
In a kind of above-mentioned switch board cable copper tube, the linkage section, inserted terminal, inserting section, climbs at connecting pin
The equal round-corner transition in edge of section and conical surface section.It thus is avoided that electric current generates tiny electric arc in edge, makes electric current conductive process
Stablize.
In a kind of above-mentioned switch board cable copper tube, the connecting pin is equipped with and threaded hole in the inside of threaded hole
The hex hole of coaxial arrangement.Hex hole conveniently tightens this switch board cable copper tube, plays anti-off effect.
Compared with prior art, this switch board is easy to connect with cable copper tube, and anti-offability is good, and structural strength is high, Er Qiekang
Rush of current ability is good, and electric current conduction stability is good, and service life is long.
