## Title
Crush rib housing for postive lock receptacle

## Abstract

A receptacle connector that includes a positive lock receptacle, wherein the positive lock receptacle includes a wire receiving portion; and a housing insertion portion, wherein the housing insertion portion further includes a first electrical contact roll and a second electrical contact roll; and a housing adapted to receive the positive lock receptacle, wherein the housing includes: an insulating housing body; and a first crush rib positioned within the insulating housing body and a second crush rib positioned within the insulating housing body, wherein the first and second crush ribs engage and secure the first and second electrical contact rolls respectively upon insertion of the housing insertion portion of the positive lock receptacle into the housing.

## Background
BACKGROUND OF THE INVENTION
The described invention relates in general to electrical connectors, and more specifically to an insulated housing that includes multiple crush ribs for securely retaining a positive lock receptacle that has been inserted into the insulated housing.
Receptacle connectors are commonly used devices in various electronics applications. Such devices typically include two primary components: (i) a terminal or receptacle for receiving and terminating a wire; and (ii) a housing for receiving the receptacle. When properly assembled, a de-insulated wire is inserted into the receptacle, and the receptacle is inserted into the housing. A protective cap may be placed over the housing to enclose the wire and receptacle. The assembly is then connected (i.e., mated) to another wire or electrical device, as may be appropriate.
Certain receptacles are designed as “positive lock” receptacles and include unique characteristics such as reduced mating forces and a large locking dimple on flexible latch. This locking feature acknowledges proper mating with an audible “snap” of the locking dimple into a corresponding mating aperture. This design enhances safety and reliability of the mated pair for isolated and hard to reach areas. Until the release latch is depressed manually the receptacle cannot be removed from the housing. Thus, the potential of exposed live parts or disruption of critical circuitry due to improperly seated or accidentally removed terminals is greatly reduced. However, in certain situations, the assembled connector may be under considerable force or tension that can result in the receptacle being pulled loose from the housing, even in the presence of a positive lock configuration. Accordingly, there is an ongoing need for a housing that includes certain additional structural features for effectively retaining the receptacle within the housing following assembly of the receptacle connector.
SUMMARY OF THE INVENTION
The following provides a summary of certain exemplary embodiments of the present invention. This summary is not an extensive overview and is not intended to identify key or critical aspects or elements of the present invention or to delineate its scope.

DETAILED DESCRIPTION OF THE INVENTION
Exemplary embodiments of the present invention are now described with reference to the Figures. Reference numerals are used throughout the detailed description to refer to the various elements and structures. Although the following detailed description contains many specifics for the purposes of illustration, a person of ordinary skill in the art will appreciate that many variations and alterations to the following details are within the scope of the invention. Accordingly, the following embodiments of the invention are set forth without any loss of generality to, and without imposing limitations upon, the claimed invention.
As previously stated, the present invention provides an insulated connector housing that includes multiple crush ribs for securely retaining a positive lock receptacle that has been inserted into the connector housing. With reference to the Figures, FIGS. 1 and 2 provide illustrations of an exemplary positive lock terminal or receptacle for use with the connector housing of this invention. As shown in FIGS. 1-2, exemplary positive lock terminal/receptacle 100 includes insulation barrel 102 and housing insertion portion 104. Insulation barrel 102 further includes first carrier strip 110, insulation crimp 112, wire barrel crimp 114, ergonomic retention wall 116, and second carrier 118. Housing insertion portion 104 includes first electrical contact roll 120, second electrical contact roll 122, locking dimple 124, and release latch 126.
FIGS. 3-6 provide illustrations of a crush rib connector housing 200 in accordance with an exemplary embodiment of the present invention, wherein crush rib connector housing 200 is adapted to receive positive lock receptacle 100 and securely retain positive lock receptacle 100 therein. As shown in FIGS. 3-6, connector housing 200 includes mating end 202 for joining or mating with other connectors and receptacle insertion end (wire exit) 204 for receiving housing insertion portion 104 of positive lock receptacle 100. Connector housing 200 further includes insulating body 210 (the material of which provides electrically insulating properties to connector housing 200), retaining tabs 212, first crush rib 214, second crush rib 216, positive lock CAM 218, first contact stop 220, second contact stop 222, and third contact stop 224, all of which serve to properly position housing insertion portion 104 within connector housing 200. As shown in FIG. 7, protective cap 300 includes body 302 and retaining arms 304 formed thereon that cooperate with retaining tabs 212 formed on the housing body 210 for connecting cap 300 to housing 200 and enclosing positive lock receptacle 100 therein.
When properly assembled, an electrical wire is terminated to positive lock receptacle 100, which is then inserted into connector housing as shown in FIG. 7. Upon exerting sufficient force, first and second electrical contact rolls 120 and 122 engage first and second crush ribs 214 and 216, respectively. During the insertion process, crush ribs 214 and 216 deform, thereby ensuring a tight and secure fit between electrical contact rolls 120 and 122 and connector housing 200 without creating significant stress on the contact rolls. Cap 300 is then attached to connector housing 200 to form the complete receptacle connector.
While the present invention has been illustrated by the description of exemplary embodiments thereof, and while the embodiments have been described in certain detail, there is no intention to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention in its broader aspects is not limited to any of the specific details, representative devices and methods, and/or illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the general inventive concept.
