Abstract
There is provided a connector including: a sacrificial pressing surface that is provided in a second housing and is a flat surface formed at an end portion on a side opposite in an insertion direction of the second housing. When an external force acts on the second housing in a temporarily assembled state in which the second housing is more shallowly fitted to a first housing than in a fully assembled state and a locking portion is not locked to a locked portion, the sacrificial pressing surface is configured to cause a pressing force to act in a direction in which a contact area of the locked portion with respect to the locking portion is larger than that in a case in which the second housing is pressed in the insertion direction.
Claims5
A connector comprising:
- a first housing that accommodates a terminal fitting that extends in an insertion direction;
- a second housing that accommodates a terminal that extends in the insertion direction, the second housing is inserted into the first housing in the insertion direction to be fitted to the first housing with the terminal inserted into the terminal fitting in the insertion direction, and the second housing restricts detachment of the terminal fitting accommodated in the first housing in the insertion direction;
- a locked portion provided on the second housing;
- a locking portion that is provided flexibly and deformably in the first housing and fits with the locked portion to move over the locked portion by becoming deformably bent along with the first housing and the second housing being fitted with each other, so as to configure a fully assembled state in which the detachment of the terminal fitting is restricted;
- and
- a sacrificial pressing surface that is provided in the second housing and is a flat surface formed at an end portion spaced away from the first housing in the insertion direction of the second housing, the flat surface is inclined relative to the insertion direction, wherein
- the locking portion includes a contact surface and the locked portion includes a tapered surface that is inclined relative to the contact surface when the locking portion is deformably bent during insertion of the second housing into the first housing, and
- when an external force acts on the second housing in a temporarily assembled state in which the second housing is more shallowly fitted to the first housing than in the fully assembled state and the locking portion is not locked to the locked portion, the sacrificial pressing surface is configured to cause a pressing force component of the external force to move the second housing in a direction that intersects the insertion direction and causes the tapered surface and the contact surface to approach parallel to each other such that a contact area of the locked portion with respect to the locking portion is larger than that in a case in which the second housing is pressed in the insertion direction.
