Abstract

ELECTRICAL CONNECTOR BODY HINGE ARRANGEMENT

Abstract of the Disclosure A molded thermoplastic electrical connector body has an integrally hinged part which is molded in an open position and movable to a closed position.
The hinge arrangement comprises a flexible hinge web for repeatedly pivoting the hinged part between the open and the closed positions and a frangible reinforce-ment web whlch is transverse to the flexible hinge web. The frangible reinforcement web positions the hinged part in the open position and distorts upon initial closure of the hinged part. In the first embodiment, the reinforcement web collapses under compression and in the second embodiment, the reinforce-ment web stretches under tension.

Description

~ ~ 3 C-3~89 D-6, 556 ELECTRl:CAL CONNECTOR BODY HINGE ARRANGE~!ENT
This invention relates generally to theremo-plastic electrical connector bodies and, more particu-larly, to thermoplastic eIectrical connector bodies 5 which have an integrally hinged part.
United States Patent 4,311, 355 issued to Robert G. Plyler and John A. Yurtin on January 19, 1982 discloses a connector body of the above noted type.
More specifically, the thermoplastic connector bodies 12, 14 disclosed therein, each have a flap 36, 76 which is integrally connected to the connector body by a thin portion (unnumbered) which acts as a flexible hinge.
The connector bodies are molded with the flaps in a raised open position as shown in Figure 1 of the patent drawing, In practice, the plug and socket ; connectors are machine assembled which re~uires that the molded open position of the flap or hinged part remain relatively consistent year around under varying factory temperature'and humidity conditions.
The thin hinge'configuration shown in the aforementioned patent does provide sufficient flexibility for easily closing the hinged part and maintaining hinge : integrity for subse~uent openings and closings. However, ; 25 the hinge configuration does not provide the very high de-gree o~ consistency which is desired for machine assembly, particularly when the connector body is molded of a moisture absorbent material, such as nylon.
~' The object of this invention is to provide a molded thermoplastic electrical connector body having an improved hinge arrangement which positions the open hinged part with a high'degree of consistency for year around machine assembly while providing ease of closing ~ and maintaininy hinge lntegrity for subse~uent openings ,~ 35 and closings.

Figure 7 is a bottom view of the second connector body taken substantially along the line 7-7 of Figure 6 looking in the'direction of the'arrows.
Figure 8 is a front view of the second con-nector body showing the hinged part in the closed posi~io~.
Figure 9 is an enlarged view of the second hinge arrangement taken along the line 9-9 of Figure 7 looking in the direction of the arrows~
Referring now to the drawings and particulaxly to F.~gures l through'5, there'is disclosed an electrical connector 10 comprising a plug connector body 12 made of a molded dielectric thermoplastic material, such as nylon.

The connector body 12 has a plurality of terminal ca~i~ies 14 into which terminals 16 are inser~ed through'enlarged openings 18 at the ends of the respective'terminal cavities. Each'terminal 16 :is retained in its respective'cavity by a pair of latch tangs 20 which engage an internal annular cavity shoulder as shown in Fig'ure'l.
Each terminal'~16 is attached to an insulated electrical lead 22 so that a seal sleeve 24 is also clamped on the end of the eIec~rical lead~ The seal sleeve 24 seals the'enlarged opening 18 at the end of the terminal cavity.
The connector body 12 also includes an inte grally hinged flap 26 which'is molded in an open position shown in solid lines in Figures 1, 2, 3 and 5, The terminals 16 are'inserted into the cavities 14 when the flap is in the open position. Aftex the terminals 16 are inserted and re~ained by the latch tangs 20, the flap 26 is moved to a closed posltion shown in phantom in Figure 1 and in solid lines in Figure 4. When closed, a notched end plate 28 o thP flap 26 blocks the seal sleeves 24 and provides a secondary or redundant terminal lock which prevents the terminals 16 from being pulled out of the cavities 14 by the'electrical leads 22.
25' The flap 26 also has side plates 30, each o~
which has a rectangular hole 3Z which cooperates with a nib 34 of the connector body to retain the flap 26 in the closed position.
Our invention relates to the improved hinge arrangement, indicated generally at 35, which integrally attaches the flap 26 to the connector body 12.
The hinge arrangement 36 comprises a hinge web 38 and a pair of spaced reinforcing webs 40. The hinye web 38 integrally connects an end 42 o~ the flap 26 to a flange 44 of the'connector body 12 as best shown in Figure'5. The space~ reinforcing webs 40 are 3' transverse to the'hinge web 38 so as to resist its flexure. The reinforcing webs 40 are located at the opposite ends o~ thP hinye web 38 to facilitate molding~
Each reinforcement web 40 is integrally connected to the end 4~ of the'flap 26, the hinge web 38, the flange 44 and adjacent portlons of the'connector body 120 The hinge we~ 38 is flexible enough to main-tain its integrity upon initiaI closing of the flap 26 so that the flap 26 can be'reopened and xeclosed to replace terminals. In the'case'of a nylon connector, this places a practical limit of about 0,5 mm (0.020") on the thicknes's o~ the'hinge web 38 or else the hinge web 38 tends to bec'ome'brittle'and fracture in cold dry conditions. On the'other hand, the'hinge web 38 tends to absorb moisture'and become'more'flexible in warm humid conditions. Consequently, the hinge web 38 alone is not adequate to provide a high degree of con-sistency in positioning the'open flap for year around machine'assembIy. Such positioning, however, is provided by the'reinforcing webs 40 which are transverse to the hinge'web '38 to resist its ~lexure.

The sole function of the reinforcing webs 40 is to position the flap 26 for machine assembly opera-tions. The integrity of the reinforcing webs 40 after the machine assembly operations are completed is not necessary. Consequently the reinforcing webs 40 are frangible to reduce closing ~orce require~ents. In this first arrangement, the reinforcing webs 40 distort and collapseunder compression upon initial closure of the ~lap 26 as indicated by the crease line 46 in Figure 4.
With nylonl a web thickness of about 0.25 ~m (0.10 in.) is sufficient for consistently positioning the flap 26 in the open position for machine assembly operations while at the same time being sufficiently frangible for distortion upon initial closure of the flap 26.

~z~

Referring now to Figures 6 through 9, another type of electrical connector 100 is disclosed which comprises a connector body 112 molded from a dielectric thermoplastic material, in this case polypropylene.
The connector body 112 has a terminal cavity 114 into which a shor~ing terminal (not shown) is inserted through'a s'ocket portion 116 at one end of t:he connector body.
The connector body 112 also includes an integrally hinged ~lap 120 ~or attaching the'connector body to a flat cable (not shown). The flap 120 is molded in an open position as shown in Figures 6, 7 and 9. The flat cable is laid against the side'122 of the connector body 112 which has V-shaped projections 124 for locating the flat cable. The flap 120 is then moved to a closed position shown in Figure 8. The f lap 120 has a latch 126 which cooperates with a nib 128 of the connector body to retain the''flap 120 in the closed position.
When closed, the'flap 120 clamps the flat cable against the side 122 of the connector body 112.
The'flap 120 is integrally attached to the connector body 112'by an improved hinge arrangement, indicated generally at 130~ in accordance with a second em~odiment of our invention, The hinge arrangement 130 comprises a hinge web 132 and a single reinforcing web 134. The hinge web 132 integrally connects an end 136 o~ the flap 1~0 to a flange 138 of the connector body 112 as best shown in Figures 6 and 9. The single rein~orcing web 134 is tranS~erse ~o the hinge web 132 so as to resist i~s flexure and it is located at the end of the hinge web 132 to facilitate axial molding. The reinforcement : web 134 is integrally connected to the end 136 of t'he : flap 120, the hinge web 132 and the flange 138 of the connector bvdy 112~' The hinge web 132 is flexible enough to : 5 maintain its integrity upon initial clo,sing o~ the flap 120 so that the flap 120 can be reopened and reclosed.
In the case of polypropylene, this also places a practi-cal limit of about 0O5 mm (0.020") on the thickness of the hinge web 132 to provide closing force requirements within ordinary manual capabili~iesO As before, the hinge web 132 alone is not ade~uate to provide a high degree of consistency in positioning the open flap for year around machine assembly and such positioning is 1~ provided by the reinforcing web 134 which is transverse to the hinge web 132 to resist its flexure.
As before the reinforcing web 134 is also frangible to reduce closing force requlrements and in this second arrangement, the reinforcing web 134 distorts and stretches under tension upon initial closuxe of the flap 26 as indicated in Figure 8. With polypropylene and a single reinforcing web, a web thickness from about 0.2 mm (0~008") to about 0.4 mm (0.0161') is sufficient ~or consistently positioning the ~lap 120
2.~ in the open position for machine assembly operations while at the same time being sufficiently frangible for distortion upon initial closure of the flap 120.
