Description

FEMALE ELECTRIC TERMINAL
TECHNICAL FIELD
The present invention relates to an electric terminal, particularly for automotive use, and more specifically to a female electric terminal designed to mate with a a male blade terminal. BACKGROUND ART
Female electric terminals made by blanking and bending conductive sheet metal are known, and comprise, integrally, a' box structure with contact elements cooperating with a male blade terminal, and a deformable portion for connection to a cable.
Terminals of the aforementioned type are frequently employed in the car industry on account of the good strength of the structure, which provides for protecting the contact elements against possible impact or abnormal overloading during production or handling of the terminals, wiring, on-vehicle assembly, and disassembly for maintenance or part replacements. According to a first known embodiment, the contact elements consist of one or two flexible blades cooperating elastically with one face of the male terminal for maintaining the opposite face against rigid contact surfaces formed on a wall of the box structure. Such a solution is illustrated, for example, in publications US-A-4 950 183 and FR-A-2 647 602.
Terminals of the above type, however, present several drawbacks. In particular, the use of one or more elastic blades cooperating with only one face of the male terminal provides for compensating for only relatively minor misalignment between the male and female terminals when these are connected; and the elastic forces exerted on the male terminal during insertion are not mutually balanced.
Box type female terminals are also known wherein the contact means consist of one or more pairs of identical elastic blades extending from opposite walls of the box structure and cooperating with opposite faces of the terminal. Such a solution is illustrated, for example, in publications FR-A-2 621 180 and FR-A-2 649 651.
Terminals of this type, however, despite solving the technical problems mentioned above, are not without drawbacks of their own.
In particular, the blades of such terminals define contact areas facing each other on either side of the male terminal, so that they are only suitable for use with flat blade male terminals as opposed to those with shaped, e.g. ridged cross section, blades, which are becoming increasingly more popular by virtue of requiring less material for given mechanical characteristics. DISCLOSURE OF INVENTION
It is an object of the present invention to provide a female terminal designed to overcome the aforementioned drawbacks and, in particular, to cooperate indifferently with male terminals featuring flat blades or blades with offset contact surfaces.
According to the present invention, there is provided a female electric terminal, particularly for automotive use, made of conductive sheet metal and comprising, integrally, a box structure defining an opening for insertion of a male blade terminal and having contact means cooperating with said male terminal; and a portion for connection to an electric cable; said contact means comprising first and second flexible blade means extending inwards and from opposite walls of said box structure and cooperating elastically with respective opposite faces of said male terminal; characterized by the fact that said first and second blade means are asymmetrical in relation to the plane of said male terminal, so as to define offset contact regions on the respective faces of said male terminal; said first and second blade means comprising respective elastically flexible portions of at least approximately the same flexural rigidity.

BEST MODE FOR CARRYING OUT THE INVENTION
Number 1 in Figure 1 indicates a female electric terminal particularly suitable for automotive applications. It should be stressed that terms such as ••top1',
"bottom", "front", "rear" and similar in the following description are in no way limiting, and are used purely for reasons of clarity with reference to the position of terminal 1 as shown in Figure 1.
Terminal 1 is formed in one piece from conductive sheet metal by means of blanking, pressing and bending operations. Terminal 1 substantially comprises a box structure
2 designed to cooperate with .a flat blade male terminal 3a (Figures 2, 6) or with a terminal 3b featuring a bent blade with offset contact surfaces; and a deformable portion 4 for connection to an electric cable 5. Box structure 2 substantially comprises a rear portion 6 with a closed rectangular cross section; and a front portion 7 also having a closed rectangular cross section and defining internally • an opening 8 for insertion of male terminal 3a. or 3b along plane α (Figure 2) .
Rear portion 6 and front portion 7 are separated axially and are connected integral with each other by respective elongated common lateral walls 9 perpendicular to plane α. Rear portion 6 comprises a bottom wall 10 from which connecting portion 4 extends rearwards; and a top wall 11; both of which walls 10 and 11 are parallel to each other and to plane α.
From top and bottom walls 11 and 10 of rear portion 6, respective curved contact blades 14, 15 (Figure 2) with their convex sides facing each other extend integrally towards and inside front portion 7, and, when undefor ed, define a gap smaller than the thickness of male terminal 3a or 3b.
According to the present invention, blades 14, 15 are asymmetrical in relation to plane a , so as to define offset contact regions on the opposite faces of terminal 3a or 3b.
More specifically, when viewed from above (Figure 3), top blade 14 is symmetrical in relation to the mid longitudinal plane β perpendicular to plane α, and tapers linearly towards an end portion 16 where it presents a contact 17 defined by a spherical-bowl-shaped impression with its center in plane β. A portion 18 of blade 14, extending between end portion 16- and wall 11, is flexible upon insertion of the male terminal.
When viewed from above (Figure 4) , blade 15 is symmetrical in. relation to plane β, tapers linearly towards end portion 19, is wider than blade 14, and presents, on end portion 19, two contacts 20 similar to contact 17, located symmetrically in relation to plane β, and with their respective centers in a transverse plane T perpendicular to planes α and β and through the center of contact 17. A portion 21 of blade 15, extending between end portion 19 and wall 10, is flexible upon insertion of the male terminal, and presents a longitudinal slot 22 by which it is divided into two side by side longitudinal portions 21a, 21b.
According to the present invention, blades 14 and 15 are equally deformable upon insertion of terminal 3a. or 3b so as to transmit balanced elastic reactions to the respective faces of the terminal.
For this purpose, the elastically deformable portions 18, 21 of blades 14, 15 present the same flexural rigidity, i.e. for a given thickness, the width of portions 21a, 21b is equal to half the width of portion 18 measured in the same transverse plane.
Top wall 11 of rear portion 6 consists of two portions 11a, lib integral with respective lateral walls 9 and bent 90° towards each other so as to mate end to end.
Portion 11a, from which blade 14 originates, preferably presents an end appendix 24 below the plane of wall 11 and designed to fit beneath portion lib.
Front portion 7 of box structure 2 comprises a bottom wall 25- and a top wall 26 which protect the end portions of blades 14, 15 and present a front portion of double thickness.
More specifically, wall 25 (Figure 2) presents an inner portion 27 connected integral with lateral walls 9; and an outer portion 28 bent 180° beneath inner portion 27 and extending towards rear portion 6 of box structure 2 and beyond the rear edge of inner portion 27.
Similarly, wall 26 presents an inner portion 29; and an outer portion 30 bent 180° over inner portion 29 and extending towards rear portion 6 of box structure 2 and beyond the rear edge of inner portion 29. In this case, inner portion 29 is connected integral with only one of lateral walls 9, and presents a lateral appendix 33 bent 90° downwards and mating with an upper projection 34 on the other lateral wall 9.
Figure 8 shows a flat blank 35 of terminal 1 formed by blanking a strip of conductive sheet metal, and extending integrally and transversely from a feed and guide band 36 to which are connected a succession of equally spaced identical blanks (not shown) .
For the sake of clarity, the various parts of blank 35 are indicated using the same numbering system, plus a (') , as for the corresponding components of the finished terminal in Figures 1 to 7.
Figure 6 shows a cross section of terminal 1 engaged by a flat blade terminal 3a, and wherein contact 17 cooperates ' with a central portion of one face of terminal 3a, and contacts 20 with lateral portions of the opposite face.
Figure 7 shows a cross section of terminal 1 engaged by a terminal 3b with a shaped blade, in particular, having a ridged cross section with a central rib 31 and two lateral wings 32 offset in relation to rib 31. Though made of thinner material as compared with terminal 3a, terminal 3b presents the same mechanical characteristics by virtue of its ridged structure. In this case, contact 17 cooperates with rib 31, on the face projecting in relation to wings 32, while contacts 20 cooperate with the opposite face of respective wings 32. Since the distance between the planes of the contact faces of terminal 3b is typically equal to the thickness of terminal 3a, deformation of the elastic systems defined by blades 14, 15 upon insertion of terminal 3a or 3b is identical in both cases and hence results in the same contact pressure. Consequently, electric and mechanical performance of terminal l is identical in both cases.
The fact that blades 14, 15 are asymmetrical in relation to plane α in no way impairs operation of terminal I, by virtue of blades 14, 15 exerting balanced elastic forces on male terminal 3a. or 3b during inssr ir-n r.f the terminal. '
The use of two blades 14, 15 permits correct insertion of male terminal 3a or 3b even in the event it is not positioned precisely along theoretical plane α, but is slightly offset or inclined upwards or downwards.
Terminal 1 also presents further advantages in terms of design. Blades 14, 15 extend from rear portion
6 of box structure 2 towards the terminal insertion opening 8, and not vice versa, as for example in the case of the terminal described in publication US-A-4 950 183 mentioned previously. As such, the portions joining blades 14, 15 to respective walls 11, 10 from which they originate are subjected to a limited amount of permanent deformation during manufacture, and hence are not subject to cracking which, in use, results in a local increase in resistance and, consequently, overheating.
Finally, the structure of front portion 7 provides for effectively protecting blades 14, 15.
Figure 9 shows a terminal 40 according to a further embodiment of the present invention.
Any parts of terminal 40 identical or equivalent to those of terminal 1 are indicated using the same numbering system.
Terminal 40 is identical to terminal 1 with the exception of blade 15.
In this case, in fact, blade 15 is substantially T-shaped, and comprises an end portion 19 substantially similar to the end portion of blade 15 of terminal 1; and a deformable portion ' 21 substantially -similar to deformable portion 18 of blade 14.
Figure 10 shows a blank 41 corresponding to terminal 40, ' and the various parts of which are indicated using the same numbering system as for blank 35.
Figure 11 shows a terminal 42 according to a further embodiment of the present invention. Any parts of terminal 42 identical or equivalent to those of terminal 1 are indicated using the same numbering system.
Terminal 42 is identical to terminal 1 with the exception of blade 15, which in this case is replaced by a pair of independent, side by side blades 15, each of which presents a contact 20, and comprises a deformable portion 21 of substantially half the width of deformable portion 18 of blade 14 measured in the same transverse plane .
Figure 12 shows a blank 43 corresponding to terminal 42, and the various parts of which are indicated using the same numbering system as for blank 35.
Terminals 40, 42 operate in exactly the same way and present the same advantages as described with reference to terminal 1.
To those skilled in the art it will be clear that changes may be made to terminals 1, 40 and 42 as described and illustrated herein without," however, departing from the scope of the present invention.
In particular, blades 14, 15 need not necessarily present impressions defining the contacts. In the case of blades with a flat cross section, the contact regions may be defined by simply curving the blades longitudinally, and contact with the flat surface of the male terminal is effected substantially along a generating line. The blades may also be curved transversely, in which case, contact is theoretically punctiform and in practice located in a circular area of tangency.
Finally, the female terminal according to the present invention permits the use of ridged-section male terminals turned over 180° in relation to that described, by appropriately adjusting the initial gap between the contact blades to achieve the required in-service contact pressure.
