Connector with small housing

摘要

A connector is provided with a terminal fitting, a housing, a rear holder, a rubber closures, and a spacer provided with a main body shaped cutaway-circular in cross-section, positioning the electric wire connection part and an electric wire therewithin, and two pairs of projections opposing to each other, projecting from inside of the main body where a width K1 of the cutaway is formed smaller than the diameter of the electric wire, and the diametric portion of the electric wire connection part and the electric wire are passed through between the two pairs of projections while the two pairs of projections are enlarged, so as to be positioned within the main body.

1. A connector comprising:
(a) a terminal fitting provided with an electric contact adapted to be connected with a mating terminal fitting and an electric wire connection part connected with an electric wire, the electric wire connection part having a flange projecting from outside of the electric wire connection part; (b) a housing provided with a terminal housing accommodating the terminal fitting, the terminal housing having
(i) a first housing accommodating the electric wire connection part, an end of the electric wire connected with the electric wire connection part;(ii) a second housing extending to the first housing; and(iii) a step face formed between the first housing and the second housing, wherein the electric wire connection part is contactable with the step face; (c) a rear holder attached to an end of the housing so as to prevent the terminal fitting from dropping out from the terminal housing; (d) a rubber closure attached to outside of the electric wire and press-fitted into the terminal housing; and (e) a synthetic resin spacer accommodated in the first housing of the terminal housing, the spacer being arranged between the flange and the rubber closure, and the spacer comprising:
(i) a main body shaped circular in cross-section and positioning the electric wire connection part and the electric wire therewithin, and(ii) at least a pair of projections projecting from an inner surface of the main body and opposing to each other, wherein a gap between the at least pair of projections is smaller than a diameter of the electric wire, diametrical portions of the electric wire connection part and the electric wire are positioned within the main body of the spacer in an assembly state, and the diametrical portions of the electric wire connection part and the electric wire are passed through between the at least pair of projections while the gap between the at least pair of projections is broadened, and wherein the main body of the spacer is in a cylindrical shape with a cutaway formed along an axial direction of the main body, and each pair of projections is formed on an edge of the cutaway facing each other.
