Spindle-Receiving Jack for Forming an Electrical Connection and Electrical Connector Comprising at Least One Such Jack

1. A spindle-receiving jack for forming an electrical connection through which high speed information signals flow, comprising: three resilient tongues defining a central opening for receiving a stem of a spindle which is forcibly introduced therein, wherein said resilient tongues are coaxially distributed around a longitudinal axis of the jack and define arcs of a circle, each arc inscribed with an angle at the center of the axis, each angle having a different value, each resilient tongue having its own reasonance frequency defined by its respective angle, the jack maintaining said electrical connection through two of the resilient tongues in electrical contact with the stem of said spindle when the electrical connection is subjected to an external vibration, the frequency of which corresponds to the resonance frequency of the third resilient tongue, whereby said electrical connection is not subjected to micro-cutoffs.

2. An electrical connector, for connecting therebetween electrical cables of control and monitoring apparatuses used in particular in an airplance and intended to carry high speed information, comprising: a plug having a plurality of spindles; and a socket having a plurality of jacks each for receiving one of the spindles, and, for forming electrical connections with said spindles wherein, each spindle-receiving jack comprises three resilient tongues defining a central opening for receiving a stem of a corresponding spindle which is forcibly introduced therein, wherein said resilient tongues are coaxially distributed around a longitudinal axis of the jack and define arcs of circle, each arc inscribed with an angle having a different value, each resilient tongue having its own resonance frequency defined by its respective angle, the jack maintaining said electrical connection through two of the resilient tongues in electrical contact with the stem of the corresponding spindle when the electrical connection is subjected to an external vibration, the frequency of which corresponds to the resonance frequency of the third resilient tongue, whereby said electrical connection is not subjected to micro-cutoffs.
