It is best to use different numbers, otherwise the picky examiner will ask you to modify it, which will be troublesome.
Three ways can be considered:
1) Do not write the number on the connecting piece: the circuit connecting piece has two connecting ends (101, 102)...the circuit connecting piece has three connecting ends (101, 102, 103).
2) Do not write numbers on the connecting ends: the circuit connecting piece (100) has two connecting ends...the circuit connecting piece (100) has three connecting ends.
3) The circuit connecting piece (100) has two connecting terminals (101, 102)... The circuit connecting piece (100) has three connecting terminals (101, 102, 103).
In addition, if the text can describe it clearly, it is not necessary to provide a pattern for each type.
