Nov. 20, 1962 J. H. HOPKINS ETAL TERMINAL MEANS Original Filed Aug. 15, 1959 INVENTQRS. Joseph H. Hapkms Allan S. Van Sly/re Their Attorney 3,%5,448 Patented Nov. 20, 1952 2 Claims. (Cl. 339-217) This invention relates to electrical connectors, and particularly to terminals adapted to facilitate connection therewith relative to multiple mating terminal means.
This is a divisional application of a co-pending application, S.N. 833,449, filed August 13, 1959, now Patent 2,989,723, granted June 20, 1961.
An object of this invention is to provide new and improved terminal means having structural features to facilitate connection therewith relative to multiple mating terminal means.
Another object of this invention is to provide male terminal means having increased stability relative to an insulating housing and adapted to facilitate connection involving multiple terminal mating means.
Another object of this invention is to provide a terminal means having laterally located rail portions adapted to provide a stop against movement in one direction in an insulating body and to provide stabilization of the terminal in the body to avoid tilting of the terminal which is also strengthened and stiffened by a re-enforcing rib portion extending longitudinally in alignment with a centrally-located tang of the terminal.
Still another object of this invention is to provide a male-blade terminal means having laterally-located rail portions adapted to extendlongitudinally as well as partly inwardly and always integrally with a floor portion of the terminal means also having a tang in longitudinal alignment with first and second embossed rib portions, one of the dual rib portions having less depth than the other and extending longitudinally into a male-blade portion.
Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings wherein preferred embodiments of the present invention are clearly shown.
In the drawings:
FIGS. 1, 2 and 3 are plan, side, and end views, respectively, of a male-blade terminal means in accordance with the present invention and mountable in an insulating body as shown in FIG. 4 that includes an illustration of a female terminal means positioned for connection to the insulating body and male-blade terminal means.
It is to be noted that the female terminal means such as 14b shown in FIG. 4 can be also mounted in insulating housings, complementary to recess or hollow interior 30h of the insulating body 3d. The female terminal means 14!] is provided with an embossed portion E swaged or deformed laterally to one side of a fio-or F thereof. A tang T is integral at one end with the embossed portion E and the tang is cut from the floor P such that an opening is left therein. The embossed portion E can be slightly wider than the tang and is therefore at least partially in longitudinal alignment with the tang T and opening 0. The opening 0 remains in the floor F and the tang T can be deformed or deflected relative to the floor without hindrance by engagement of outer free edges of the tang relative to edges of the opening 0 because the embossed portion E maintains a predetermined spacing of the tang T relative to the floor. Thus the tang T can be deformed or deflected temporarily for insertion tion 32s. provided a first embossed portion 32g which is swaged portion 32g.
and/or removal relative to an insulating body as shown in the Patent 2,682,038, Johnson mentioned earlier. The embossed portion E and tang T represent structure which is an improvement over that shown by Patent 2,682,038.
In FIG. 1 there is shown a male terminal means generally indicated by numeral 32 having a body portion 32a and ferrule portion 32,. The body portion has a tapered edge 32e and includes a central stabilizing portion 32s located intermediate the body portion 32a and ferrule portion 32 The stabilizing portion 32s is located in a plane parallel to a plane that passes through the blade portion 32a. A tang 32t is cut out of the stabilizing portion 32s leaving an open space 32x having rough edges relative to which the tang 321 would bind and be hindered whenever the tang 32t is deformed and temporarily bent back relative to the stabilizing por- To avoid such hindrance of the tang, there is or deformed downwardly from the stabilizing portion 32s and which is longitudinally in alignment with the tang 32: having one end integral with the first embossed The terminal means 32 is further provided with a second embossed portion 3211 having less depth than the first embossed portion 32g. The depth of the first embossed portion 32g is at least equal to and pref- .erably greater than the thickness of the tang 32L The resilience of the tang 32t is enhanced due to the presence of the embossed first portion 32g and longitudinal rigidity of the body portion 32a of the male-blade terminal means is increased relative to the stabilizing portion 32s due to the second embossed portion 32h. The second embossed portion 32h extends from the body portion 32a into the one end of the stabilizing portion 32s adja cent to and in longitudinal alignment with the first em bossed portion 32g. The second embossed portion 3211 is in a plane parallel to and intermediate to the planes of the body portion 32a and stabilizing portion 32s as can be best seen in FIGURE 2.
The stabilizing portion 32s is further provided with a laterally outwardly and upwardly extending wing structure including first parallel parts 32p and laterally inwardly extending and diverging second parts 32d. The relationship of the parallel parts 32p and diverging parts 32d with respect to the male-blade body portion 32a, the second embossed portion 32/1 and first embossed portion 32g as well as tang 321 can be best seen in FIG. 3 which is an end view also illustrating the ferrule portion 32; in an uncrimped condition. The male terminal means 32 is outlined in FIG. 4 to show fitting thereof relative to an insulating housing generally indicated by numeral 30 and having a hollow interior 39h. The exploded view of FIG. 4 illustrates a partially sectioned elevational View of a female terminal means 1412 noted previously ,and having the embossed portion E and tang T as described earlier. The hollow interior 30h of the insulating housing 39 is formed by side Walls, a pair of which are provided with longitudinally extending grooves complementary to the first parallel parts 32p of the terminal means 32. The body portion 32a of the terminal means fits into a neck portion 30m formed as an extension of the grooves 30g. The neck portion 3011 of the housing 39 is adapted tobe located laterally on opposite sides of the second embossed portion 3211 of the terminal means 32. The tang 3% of the terminal means engages a shoulder 30s formed along a bottom surface of one of the wall portions of the housing 30. A similar shoulder 30s is formed along an upper wall portion so that the terminal means 32 can be assembled into one end of the body or housing 30 in either of two opposite directions and yet properly provide for the connection to the mating female connector. The two positions are obtained by a 180 rotation aroundthe'longitudinal axis of the terminal means 32. The first and second parts 32p and 32d can be described as side rails that provide a forward stop for the terminal means 32 relative to the housing 3% while a backward'stop is obtained by the use of the tang 32t having a central location relative to the stabilizing portion 32s. These ralis enhance stabilization relative to the housing 30 and also strengthen and stiffen terminal means 32.
While the embodiments of the present invention as herein disclosed constitute preferred forms, it is to be understood that other forms might be adopted.
