Fixing structure
A fixing structure of a connector 1 includes a housing 13 and a front holder 15 . The front holder 15 includes a detection portion 151 , a latching lock 152 , and a restriction protrusion 153 . The housing 13 includes an accommodation portion 1314 , a restriction recessed portion 1315 , and a latching portion 1316 a . A restriction surface 1533 extending to cross a height direction Z is provided on the restriction protrusion 153 , and a contact surface 1315 a - 1 configured to come into contact with the restriction surface 1533 and support the restriction protrusion 153 is provided on the restriction recessed portion 1315 . When the latching lock 152 elastically deforms in the height direction Z, the restriction surface 1533 is in contact with the contact surface 1315 a - 1.
1 . A fixing structure of a connector, the fixing structure comprising:
a housing having a tubular shape, the housing configured to receive a terminal in an insertion direction; and
a front holder having a tubular shape, the front holder configured to engage with the housing in a direction opposite of the insertion direction,
wherein the front holder comprises:
an engagement confirmation portion that protrudes toward the housing in the direction opposite of the insertion direction, the engagement confirmation portion configured to prevent the terminal from being removed from the housing;
a latching lock configured to elastically deform along a deflection direction orthogonal to the insertion direction, the latching lock spaced apart from the engagement confirmation portion along the deflection direction; and
a restriction protrusion between the engagement confirmation portion and the latching lock in the deflection direction,
wherein the housing comprises:
an accommodation portion that is open toward the front holder in the insertion direction and that constitutes a space for accommodating the engagement confirmation portion;
a latching portion configured to latch the latching lock; and
a restriction recessed portion that is open toward the front holder in the insertion direction and that constitutes a space for accommodating the restriction protrusion,
wherein a restriction surface extending in a direction orthogonal to the deflection direction is provided on the restriction protrusion,
wherein a contact surface configured to come into contact with the restriction surface and support the restriction protrusion is provided on the restriction recessed portion, and
wherein, in a case where the latching lock elastically deforms in the deflection direction, the restriction surface is in contact with the contact surface.
2 . The fixing structure according to claim 1 , wherein
the restriction protrusion comprises:
a standing portion rising in a direction opposite of the deflection direction; and
a blade portion extending to both left and right sides of the standing portion, and the restriction surface is formed on a lower surface of the blade portion.
3 . A connection structure comprising:
a mating connector; and
a connector comprising the fixing structure according to claim 1 ,
wherein the mating connector is configured to engage with the housing of the fixing structure, and
wherein the mating connector comprises a prying engagement preventing portion configured to come into contact with a surface of the restriction protrusion opposite to the restriction surface such that, the restriction protrusion is sandwiched between the prying engagement preventing portion and the contact surface of the restriction recessed portion, thereby restricting displacement of the restriction protrusion in the deflection direction.
4 . The connection structure according to claim 3 , wherein the prying engagement preventing portion comprises an accommodation recessed portion configured to accommodate the restriction protrusion, and
an inner wall surface of the accommodation recessed portion is in contact with the surface of the restriction protrusion opposite to the restriction surface.
