Cross detection hole 35 and enter in demoulding space 19 (that is, in notch 36), abut with guide portion 51.The spy abutted with guide portion 51
Pin P is directed to (that is, terminal accommodating chamber 11 side) displacement downwards by the inclination of guide portion 51, therefore, it is possible to effectively with
The upper surface (contact area 28) in the square tube portion 21 of the terminal fittings 20 in terminal accommodating chamber 11 abuts.Probe P constitutes round
Cylindricality, therefore contact area 28 is linear contact lay with the form that contacts of probe P.
When probe P contacts with contact area 28, the terminal part of probe P does not arrives restriction projection 25.Therefore, make
Restriction projection 25 for the fixture structural unit locking with convex shaped part 14 will not or deformation impaired because of probe P.And, the end of probe P
End abuts with guide portion 51 from below, and abuts with contact area 28 from top, thus is connected at upper and lower two positions
Adapter C.The terminal part of the probe P being clipped in up and down between guide portion 51 and contact area 28 is positioned in the vertical direction
(limiting mobile).
And, contact area 28 is the tabular surface rectangular with the abutting direction of terminal fittings 20 relative to probe P.And
And, putting down with the direction of insertion of probe P on the perspective plane parallel with contact area 28 towards being formed as of the gradient of guide portion 51
OK.Therefore, even at terminal fittings 20 and probe P at left and right directions (direction of insertion relative to probe P and probe P and end
Subassembly 20 abut rectangular direction, the two direction, direction) in the case of upper relative displacement, probe P and contact area 28
Contact condition also will not change.
It addition, structure than the above described structure is identical with above-described embodiment 1, therefore it is marked with identical for identical structure
Label, and omit the explanation of structure, effect and effect.
