[57] ABSTRACT A female electrical terminal for receiving a blade terminal is disclosed. The main elements forming the female terminal are first, second, third and fourth walls which are joined together into an integral unit at edges between the first and the second, the second and the third, and the third and the fourth walls. A cooperable lock device is formed, in part, on a free end of the first wall and, in part, on a free end of the fourth wall. The cooperable lock device locks the walls into a closed configuration to define therein an interior volume in which the first and the third walls are in facing relationship and the second and the fourth walls are in a facing relationship. Individual ones of a pair of terminal elements are formed integrally from respective ones of a pair of facing walls. Each of the terminal elements is folded back from its point of attachment to the wall into the interior volume of the terminal to form a main blade terminal contacting portion which is resiliently deflectable when engaged by an inserted blade terminal.
9 Claims, 4 Drawing Figures ELECTRICAL TERMINAL BACKGROUND OF THE INVENTION The prior art teaches many electrical terminal constructions for electric terminals of a female type which accept a blade terminal therein. Many of the electrical terminals of this general type are designed to be mounted in an assembly operation along with other similar terminals in a terminal block thereby to form an electrical connector.
It is a general purpose of this invention to provide a female electrical terminal which is designed to be stronger than known prior art female terminals. The construction features of the female terminal of this invention are such that the terminal may be inserted into a terminal block to form an electrical connector without fear that the internal, operative portions of the terminal will be damaged by such a connector assembly operation. The female terminal of this invention also is designed so that it may receive a blade electrical terminal therein in such a manner that a uniform, positive gripping pressure is applied to the blade terminal by the internal operative portions of the female terminal.
SUMMARY OF THE INVENTION This invention relates to an electrical tenninal and, more particularly, to a female electrical terminal for receiving a blade terminal therein.
In accordance with the teachings of this invention, a female electrical terminal for receiving a blade terminal therein includes the following general structure. First, second, third and fourth walls are provided to define upper and lower walls and a pair of side walls for the electrical terminal. The walls are integrally joined along edges between ,the first and the second wall, between the second and third wall, and between the third and the fourth wall. A cooperable lock device is formed, in part, on a free end of the first wall and, in part, on a free end of the fourth wall. This lock device locks the four walls into a closed configuration defining an interior volume in which both the upper and the lower walls and the side walls are in facing relationship. Individual ones of a pair of terminal elements are formed integrally from each of a pair of facing walls. Each terminal element is folded from its point of attachment to its associated wall into the interior volume of the terminal to form a main blade terminal contacting portion. This contacting portion is resiliently deflectable when engaged by a blade terminal inserted into the interior volume of the electrical terminal.
In accordance with more detailed aspects, the female terminal of this invention may also include the following structural features. Each of the pair of terminal elements may have an additional portion which is folded back between the main terminal contacting portion thereof and the wall from which it is integrally formed. This folded back portion of the terminal element can be brought into engagement with its associated wall to give added flexibility and spring action to the terminal element when a blade terminal is inserted into the interior volume of the female terminal. The female terminal of the invention may also be formed so as to have a stop element which limits the resilient travel of the main blade terminal contacting portion of the terminal element. Also, each of the terminal elements may be bifurcated along a major portion of their length so as to provide uniform gripping pressure on the blade terminal brought into contact therewith.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a front elevation view of an electrical terminal constructed in accordance with the teachings of this invention.
FIG. 2 is a side elevation view of the left hand side of the electrical terminal shown in FIG. 1.
FIG. 3 is a cross section view showing some of the internal structure of the terminal.
FIG. 4 is a perspective view showing the electrical terminal in an unfolded condition wherein the various details of the structure are shown.
DESCRIPTION OF THE PREFERRED EMBODIMENT CONSTRUCTION The female electrical terminal of this invention is generally identified by the numeral 10 in the drawings. The electrical terminal has a first wall 12, a second wall 14, a third wall 16, and a fourth wall 18 (FIG. 4). All of these walls are formed as an integral unit by being joined together along edges thereof between the first and the second walls, between the second and the third walls, and between the third and the fourth walls.
A cooperable locking device is formed integrally with the terminal 10. This device includes a tab 20 extending from a free end of the first. wall 12 and an opening 22 in a lip portion 24 formed on the free end of the fourth wall 18 (FIG. 4). When the tab 20 is snapped into the opening 22, the electrical] terminal has its four walls formed into a closed rectangular configuration whereby the first and the third walls 12 and 16 respectively define a pair of facing upper and lower walls (FIG. I) and the second and the fourth walls 14 and 18 define a pair of facing side walls.
Electrical terminal elements, generally identified by the numeral 26, are formed integrally with and extend from the upper wall 16 and the lower wall 12. Each terminal element is of the same general configuration. As may best be understood by reference to FIGS. 3 and 4, each element is folded back from its point of attachment to its associated wall to form both a closed entry portion 27 and a main terminal contacting portion 28 within an interior volume 30 of the terminal 10.
Each of the electrical terminals 26 may also have a folded back portion 32 (FIG. 3) having a free end which engages the associated wall from which the terminal element is integrally formed. This engagement gives added flexibility and spring action to the terminal elements 26 when a blade terminal 34 (FIG. 2) is inserted therebetween. The folded back portion 32 acts to provide a spring force on the inserted terminal 34 along the entire length of the mainterminal contacting portions 28 thereby giving a uniform contact pressure along the entire length of the blade terminal.
A stop element 36 is formed as a lip turned up from an opening 38 in the first wall 12 and an opening 40 in the third wall 16. The stop elements 36 may be formed integrally with the formation of the walls and the electrical terminals as, for example, in a sequential stamping operation wherein suitable electrically conductive material is formed into the terminal 10. The stop el'ements are provided for limiting the resilient travel of the main terminal contacting portions 2% of the terminal elements 26 within the interior volume 36 of the terminal.
As may best be seen in H63. 1 and s, the terminal elements 26 are bifurcated by a slot 42 along a major portion of their lengths. This bifurcation of the terminal elements allows a uniform gripping pressure to be applied by the terminal contacting portions 28 thereof on the blade terminal 34 when inserted therebetween.
As seen in FIG. 2, a lower portion of the third wall 16 of the terminal is formed to have wire gripping elements 44 thereon. This wire gripping elements engage and make electrical contact with electrical wires d6 from a suitable electrical lead. The termination of the terminal to the wires 56 is accomplished in a standard manner.
OPERATION The female terminal 10 of this invention is designed to receive the blade terminal 34 therein as is illustrated in FIG. 2. The blade terminal 34 is inserted between opposed terminal elements 26 to engage initially the closed entry portions 27 and then the terminal contacting portions 28 of the elements. Because the closed entry portions 27 are spaced apart along their initial portions a distance greater than the thickness of the inserted blade terminal, the blade terminal is easily captured in the terminal 10 and the final insertion pressure does not have to be high. The engaged portions of the elements are deflected within the interior volume 30 of the terminal 10. The deflection of the terminal elements builds up a spring force between the folded back portions 32 of the elements and their associated engaged walls. By such action, a positive gripping pressure is applied to the blade terminal 34 by the main contacting portions 28 of the terminal elements 26 to insure good electrical contact therewith. The bifurcation of the terminal elements permits a uniform side-toside contact pressure to be exerted on the inserted blade terminal. Also, since the four walls of the terniinal 10 are locked together into an integral unit, rigidity is provided to the entire structure and repeated insertion and removal of the blade terminal 34 from the terminal elements 26 does not cause substantial changes in the electrical characteristics of the electrical junction formed therebetween.
The construction of an electrical terminal of the female type has been disclosed herein. Modifications of the terminal's construction which do not depart from the spirit and scope of this invention will be obvious to those skilled in the art in view of this disclosure. It is intended that all such constructions be included within the terms of the appended claims.
