The present invention relates to a female electrical receptacle for receiving and making electrical contact with a male electrical terminal. One side of the receptacle is in the form of a resilient leaf spring folded about a side margin thereof which is integral with the receptacle. The leaf spring resiliently engages against a male terminal received in the receptacle to make an electrical connection therewith. The receptacle is further provided with an elongated helper spring folded about a side margin thereof which is integral with the receptacle. The helper spring is shorter than the leaf spring and has a free end which overlies the leaf spring. Upon insertion of a male terminal into the receptacle, the male terminal will resiliently deflect the leaf spring contact against the helper spring. The helper spring thereby serves to stiffen the spring contact to provide a relatively high gripping pressure on the male terminals. The spring contact further is deflected by the male terminal into engagement with the helper spring along its folded edge margin which resists the tendency of the spring contact to unfold and further serves to limit the deflection of the leaf spring to prevent deformation thereof. The helper spring also distributes the stresses along a substantial length of the leaf spring to prevent deformation thereof due to overstressing. In a modification, the receptacle may be provided with a folded tab portion overlying the free end of the spring contact against which the free end of the contact will engage to limit the deflection thereof when a male terminal is received in the receptacle. |
