ABSTRACT:
A connector includes a connector body provided with a plurality of pin-like terminals and a retainer provided with through-holes, through which the terminals are passed, for maintaining regular pitches of the terminals and preventing the terminals from being deformed. The retainer is provided with a thin film formed so that it may be fractured by passing the terminal through at least one through-hole of a plurality of through-holes, and the fractured portion may be elastically engaged with an outer circumferential surface of the inserted terminal. Diameters of all of the through-holes including the above through-hole are adapted to be larger than an outside diameter of the terminals as taken along the entire axial length of the through-holes. Upon inserting the terminals of the connector body into the through-holes of the retainer, the thin film is fractured by the terminals and the fractured portion is elastically engaged with the outer circumferential surface of the inserted terminals to support the retainer by the terminals. In addition, since the diameter of all of the through-holes is adapted to be larger than that of the terminals, the tolerances of the diameter are easy to meet and the formation of the terminals during the production of the retainer can thus be made easy.
