The body is formed from a first material and includes a connection section and a contacting section with the contacting section having a flexible contact beam and an opposing stationary beam for receiving a male pin of a mating terminal. The covering is formed from a second material that can have a higher tensile strength than the first material and is secured to the body. The covering includes a stiffening beam and a support beam that engages the flexible contact beam providing increased normal force to the flexible contact beam. ## Claims ### Claim 1 A terminal comprising: a body, the body formed of a first material, the body having a longitudinal insertion axis and having a connection section along an end portion of the terminal and a contacting section extending away from the connection section, the connection section having a flexible contact beam and a stationary contact beam, the flexible contact beam cantilevered from a first point, the stationary beam opposes the flexible contact beam and the wire securing portion having a wing; and a covering, the covering formed of a second material, the covering having a peripheral contour, the peripheral contour is divided by a middle wall, the middle wall defining an upper section and a lower section, the upper section including a locking arm that extends toward the connection section, the lower section including a stiffening beam, the stiffening beam formed from the middle wall and cantilevered from a second point, the stiffening beam engages the flexible contact beam at a third point, the second point is disposed between the first point and the third point, wherein the body is supported by the lower section. ### Claim 2 (depends on 1) The terminal of claim 1, wherein a support beam engages the stiffening beam. ### Claim 3 (depends on 2) The terminal of claim 2, wherein the support beam is formed from the middle wall. ### Claim 4 (depends on 1) The terminal of claim 1, wherein the stiffening beam includes a tab. ### Claim 5 (depends on 4) The terminal of claim 4, wherein the tab limits the deflection of the beams. ### Claim 6 (depends on 1) The terminal of claim 1, wherein a first securing tab is formed on the body and a second securing tab is formed on the covering and the tabs are disposed in a slot formed on the body. ### Claim 7 (depends on 6) The terminal of claim 6, wherein the tabs are disposed in a second slot formed in the covering. ### Claim 8 (depends on 1) The terminal of claim 1, wherein the wing includes a coined edge having a first portion and a second portion. ### Claim 9 (depends on 8) The terminal of claim 8, wherein the first portion includes a bevel. ### Claim 10 (depends on 8) The terminal of claim 8, wherein the first portion has a first height and the second portion has a second height and the first height is greater than the second height. ### Claim 11 (depends on 10) The terminal of claim 10, wherein the first portion has a first thickness and the second portion has a second thickness and the first thickness is less than the second thickness. ### Claim 12 (depends on 11) The terminal of claim 11, wherein the first portion includes a bevel. ### Claim 13 A terminal comprising: a body having a slot, a tab, a stationary beam and a flexible beam, the stationary beam and the flexible beam opposing each other; a covering that is a separate piece, having an upper section and a lower section formed in the covering, the covering having a securing tab, the covering having a stiffening beam that supports the flexible beam; and wherein the tab on the body and the securing tab on the covering are disposed in the slot. ### Claim 14 (depends on 13) The terminal of claim 13, wherein the covering provides a support beam that supports the stiffening beam and increases a normal force required to deflect the flexible beam. ### Claim 15 (depends on 13) The terminal of claim 13, wherein the body is formed from a first material and the covering is formed from a second material and the tensile strength of the second material is greater than the tensile strength of the first material. ### Claim 16 A method for producing a terminal comprising: providing a body with a flexible beam and a stationary beam that oppose each other, and further including a first tab and a first slot; providing a covering with an upper section and lower section having a middle wall separating the sections, a stiffening beam formed from the middle wall, and further including a second tab and a second slot; and joining the covering to the body by inserting the body into the lower section so the stiffening beam engages the flexible beam and forming the covering so that the first tab and the second tab extend through the first slot and the second slot.
