Abstract

An electrical connector assembly facilitates the establishment of an electrical connection with a terminal on an electrical component when the component and the connector assembly are brought toward each other with the connector assembly in a first orientation relative to the component, and for inhibiting the establishment of an electrical connection with the terminal on the electrical component when the component and the connector assembly are brought toward each other with the connector assembly in a second orientation relative to the component, opposite the first direction. In a preferred embodiment, the connector assembly comprises an insulative housing having a top surface, a bottom surface, a front side, and a rear side; a compartment in the housing defined by a longitudinal opening in the top surface and an opening in the rear side; an aperture in the housing communicating between the front side and the compartment; and a spring contact element disposed in the compartment and comprising a cantilevered portion defined between a front leg and a rear leg. The cantilevered portion extends through the longitudinal opening, the front leg extends through the aperture to form a front terminal lead, and the rear leg extends through the opening in the rear side to form a rear terminal lead. The cantilevered portion is sloped away from the housing as the it extends in the direction from the front side of the housing to the rear side of the housing.

Claims

1. An electrical connector assembly, comprising:

an insulative housing having a top surface, a bottom surface, a front side, and a rear side;

a compartment in the housing defined by a longitudinal opening in the top surface and an opening in the rear side;

an aperture in the housing communicating between the front side and the compartment; and

a spring contact element disposed in the compartment and comprising a cantilevered portion defined between a front leg and a rear leg;

wherein the cantilevered portion extends through the longitudinal opening, the front leg extends through the aperture to form a front terminal lead, and the rear leg extends through the opening in the rear side to form a rear terminal lead.

2. The connector assembly of claim 1, wherein the front and rear terminal leads are directed toward each other under the bottom surface of the housing to form front and rear surface mount terminal leads, respectively.

3. The connector assembly of claim 1, wherein the contact element comprises a unitary, one-piece structure.

4. The connector assembly of claim 1, wherein the cantilevered portion is configured to facilitate the establishment of an electrical connection with a terminal on an electrical component by means of a substantially unidirectional sliding motion of the component in a first direction from the front side of the housing to the rear side of the housing, while inhibiting the establishment of an electrical connection by the motion of the component in a second direction opposite to the first direction.

5. The connector assembly of claim 4, wherein the cantilevered portion is sloped away from the housing as the cantilevered portion extends in the direction from the front side of the housing to the rear side of the housing.

6. A method of manufacturing an electrical connector assembly, comprising the steps of:

(a) providing an insulative housing having a top surface, a bottom surface, a front side, a rear side, a compartment defined by a longitudinal opening in the top surface and an opening through the rear side, and an aperture through the front side communicating with the compartment;

(b) providing a spring contact element comprising a cantilevered portion defined between a front leg and a rear leg;

(c) installing the spring contact element in the compartment so that the cantilevered portion extends upwardly through the longitudinal opening, the front leg extends forwardly through the front side of the housing, and the rear leg extends rearwardly through the rear side of the housing; and

(d) forming the front and rear legs into front and rear terminal leads, respectively.

7. The method of claim 6, wherein the forming step comprises the step of directing the front and rear legs toward each other under the bottom surface of the housing to form front and rear surface mount terminal leads, respectively.

8. The method of claim 6, wherein the step of providing the spring contact element comprises the steps of:

(b)(1) providing a flat piece of conductive metal having first and second substantially parallel prongs extending in a first direction, and a third prong extending in a second direction opposite to the first direction;

(b)(2) directing one of the first and second prongs back over itself toward the third prong to form a cantilevered portion; and

(b)(3) turning the other of the first and second prongs 180 degrees around its longitudinal axis so that it substantially underlies the cantilevered portion, thereby forming the front leg;

whereby the third prong forms the rear leg.

9. An electrical connector assembly for establishing an electrical connection with a terminal on an electrical component when the component and the connector assembly are brought toward each other with the connector assembly in a first orientation relative to the component, and for inhibiting the establishment of an electrical connection with the terminal on the electrical component when the component and the connector assembly are brought toward each other with the connector assembly in a second orientation relative to the component, opposite the first direction, the connector assembly comprising:

an insulative housing having a top surface, a bottom surface, a front side, and a rear side;

a compartment in the housing defined by a longitudinal opening in the top surface and an opening in the rear side;

an aperture in the housing communicating between the front side and the compartment; and
