Combination terminal including resilient lock piece
A combination terminal includes a first terminal fitting ( 11 ) including a first base plate portion ( 12 ) and a second terminal fitting ( 51 ) including a second base plate portion ( 52 ) to be stacked on the first base plate portion ( 11 ), the second terminal fitting ( 51 ) being assembled with the first terminal fitting ( 11 ) by being displaced in a direction intersecting a stacking direction. The first terminal fitting ( 11 ) is formed with a resiliently deformable resilient lock piece ( 20 ). The second terminal fitting ( 51 ) is formed with a lock portion ( 56 ) for locking the first and second terminal fittings ( 11, 51 ) in an assembled state by being locked to the resilient lock piece ( 20 ). A protecting member ( 40 ) for preventing interference of an external matter with the resilient lock piece ( 20 ) is attached to the first terminal fitting ( 11 ).
1 . A combination terminal, comprising:
a first terminal fitting including a first base plate portion; and
a second terminal fitting including a second base plate portion to be stacked on the first base plate portion, the second terminal fitting being assembled with the first terminal fitting by being displaced in a direction intersecting a stacking direction,
the first terminal fitting being formed with a resiliently deformable resilient lock piece and a first positioning portion,
the second terminal fitting being formed with:
a lock portion for locking the first and second terminal fittings in an assembled state by being locked to the resilient lock piece; and
a second positioning portion to be fit to the first positioning portion, and
a protecting member for preventing interference of an external matter with the resilient lock piece being attached to the first terminal fitting,
wherein the first positioning portion is configured to position the second positioning portion when assembly of the first and second terminal fittings is started, and
the first positioning portion is disposed radially outward of the resilient lock piece.
2 . The combination terminal of claim 1 , wherein the protecting member has a guide surface to be brought into sliding contact with the second terminal fitting in the process of assembling the first and second terminal fittings.
3 . The combination terminal of claim 1 , wherein:
the first and second terminal fittings are assembled while being relatively rotated, and
the resilient lock piece has an arc shape extending concentrically with a center of rotation at the time of assembling the first and second terminal fittings.
4 . The combination terminal of claim 1 , comprising a first sub-terminal to be stacked and assembled with the first terminal fitting, wherein:
the first sub-terminal is formed with a third positioning portion for positioning the second terminal fitting when the assembly of the first and second terminal fittings is started.
5 . The combination terminal of claim 1 , comprising a first sub-terminal to be stacked and assembled with the first terminal fitting from a side opposite to the second terminal fitting, wherein:
the resilient lock piece is resiliently displaced toward the first sub-terminal due to interference with the second terminal fitting in the process of assembling the first and second terminal fittings and resiliently returns and is locked to the lock portion when assembly of the first and second terminal fittings is completed, and
the first sub-terminal is formed with a deflection allowance space for enabling resilient deformation of the resilient lock piece.
6 . The combination terminal of claim 1 , wherein:
the first base plate portion includes a projection-like contact point portion to be brought into contact with the second base plate portion with assembly of the first and second terminal fittings completed, and
the second base plate portion is formed with an interference avoiding portion for avoiding interference with the contact point portion when the assembly of the first and second terminal fittings is started.
7 . The combination terminal of claim 1 , wherein the first positing portion includes a positioning recess, and
the second positioning portion includes a folded portion.
8 . The combination terminal of claim 7 , wherein the first terminal fitting further includes a fitting portion to be fit to the folded portion in the assembled state.
