A connector is disclosed for use in automotive applications, which has improved retention capabilities. The connector includes a body portion that supports an array of conductive terminals. An outer housing is molded over the body portion and the terminal termination area to form an exterior protective housing of the connector. The protective housing of the connector is provided with a pair of engagement arms formed on the exterior of the protective housing. The arms are connected to the housing at their opposite ends and are formed with an intervening space between them and the housing. The space is configured to provide an outward bias force on the engagement arms such that when the connector is inserted into a receiving frame, the engagement arms are biased outwardly to press against sidewalls of the receiving frame and retain the connector in place therein without the need for additional latches or O-rings.

1. A connector for insertion into a receiving frame, the connector comprising: a cable, the cable enclosing a plurality of wires;a plurality of conductive terminals, the terminals terminated to the cable wires at a termination area, the terminals being supported by, and the termination area being enclosed by, an internal body portion of the connector, the internal body portion including a premolded mass of material; anda protective housing enclosing the termination area, the housing including a pair of engagement arms and at least one catch member, the engagement arms extending lengthwise from parallel sides of the connector, each engagement arm including a backbone portion, each backbone portion terminating in two opposing ends, each backbone portion being spaced from the housing by an intervening opening, the opening having a configuration that biases the backbone portion outwardly from the housing, urging the connector rearward, each catch member extending from a top side of the connector, the top side being perpendicular to the parallel sides;wherein the engagement arms and each catch member serve to affix the housing within the frame both horizontally and vertically, and centers the housing horizontally within the frame. 2. The connector of claim 1, wherein the frame includes at least a pair of sidewalls, the sidewalls cooperatively defining a connector-receiving passage for receiving the connector therein, the engagement arms engaging the sidewalls when the connector is inserted into the frame. 3. The connector of claim 2, wherein each backbone portion includes a protrusion, and each sidewall includes a recess, each recess receiving a corresponding protrusion when the connector is fully inserted into the frame. 4. The connector of claim 1, wherein each engagement arm includes a protrusion, the protrusion disposed between ends of the engagement arm. 5. The connector of claim 4, wherein the protrusion extends outwardly from each backbone. 6. The connector of claim 1, wherein each opening has a width, the width varying lengthwise along the opening. 7. The connector of claim 1, wherein the ends of each engagement arm comprise a proximal end and a distal end, a body of each engagement arm being spaced apart from the housing by a first spacing and a second spacing, the first spacing being near the distal end, the second spacing being near the proximal end. 8. The connector of claim 7, wherein the second spacing is greater than the first spacing. 9. The connector of claim 1, wherein each engagement arm includes a reinforcement member. 10. The connector of claim 9, wherein the reinforcement member includes a flexible insert, the flexible insert extending within a body of each engagement arm and between the opposing ends. 11. The connector of claim 9, wherein the reinforcement member extends within a body of the engagement arm and into a body of the housing. 12. The connector of claim 1, wherein each engagement arm is formed separately from a body of the housing, the opposing ends thereof being attached to the housing. 13. The connector of claim 4, wherein each protrusion is disposed on the engagement arms at a location rearward of the termination area. 14. The connector of claim 2, wherein each sidewall includes flat surface, the surfaces being angled away from each other, rearwardly within the frame such that when the connector is inserted into the frame, the engagement arms bias the housing rearwardly within the connector-receiving passage against stop surfaces of the receiving frame. 15. A connector-frame assembly, the connector-frame assembly comprising: a cable, the cable enclosing a plurality of wires;a connector including a plurality of conductive terminals, the terminals terminated to the cable wires at a termination area, the terminals being supported by, and the termination area being enclosed by, an internal body portion of the connector, the internal body portion including a premolded mass of material, a protective housing enclosing the termination area, the housing including a pair of engagement arms and at least one catch member, the engagement arms extending lengthwise from parallel sides of the connector, each engagement arm including a backbone portion, each backbone portion terminating in two opposing ends, each backbone portion being spaced from the housing by an intervening opening, the opening having a configuration that biases the backbone portion outwardly from the housing, urging the connector rearward, each catch member extending from a top side of the connector, the top side being perpendicular to the parallel sides; anda connector-receiving frame, the connector-receiving frame including at least a pair of sidewalls, the sidewalls cooperatively defining a connector-receiving passage for receiving the connector therein, the engagement arms engaging the sidewalls when the connector is inserted into the connector-receiving frame;wherein the engagement arms and each catch member serve to affix the housing within the frame both horizontally and vertically, and centers the housing horizontally within the frame. 16. The connector-frame assembly of claim 15, wherein the opposing ends comprise a proximal end and a distal end, a body of each engagement arm being spaced apart from the housing by a first spacing and a second spacing, the first spacing being near the distal end, the second spacing being near the proximal end, the second spacing being greater than the first spacing. 17. The connector-frame assembly of claim 16, wherein each sidewall includes flat surfaces, the surfaces being angled away from each other, rearwardly within the connector-receiving frame such that when the connector is inserted into the connector-receiving frame, the engagement arms bias the protective housing rearwardly within the connector-receiving passage and against stop surfaces of the connector-receiving frame. 18. A connector for insertion into a receiving frame, the connector comprising: a cable, the cable enclosing a plurality of wires;a plurality of conductive terminals, the terminals terminated to the cable wires at a termination area, the terminals being supported by, and the termination area being enclosed by, an internal body portion of the connector, the internal body portion including a premolded mass of material; anda protective housing enclosing the termination area, the housing including a pair of engagement arms and at least one catch member, the engagement arms extending lengthwise from parallel sides of the connector, each engagement arm including a backbone portion, each backbone portion terminating in two opposing ends, each backbone portion being spaced from the housing by an intervening opening, the intervening opening having a configuration that biases the backbone portion outwardly from the housing, the opposing ends including a proximal end and a distal end, a body of each engagement arm body being spaced apart from the housing a first spacing and a second spacing, the first spacing being near the engagement arm distal end, the second spacing being near the engagement arm proximal end, the second spacing being greater than the first spacing so as to exert an outward force on the engagement arms, urging the connector rearward, each catch member extending from a top side of the connector, the top side being perpendicular to the parallel sides;wherein the engagement arms and each catch member serve to affix the housing within the frame both horizontally and vertically, and centers the housing horizontally within the frame. 19. The connector of claim 18, wherein the protrusion extends outwardly from the backbone portion. 20. The connector of claim 18, wherein the protrusions are disposed on the engagement arms at a location rearward of the termination area.
