5 Claims, 5 Drawing Figures PATENTEDUBT 17 I972 INVENTOR PETER MARTIN BRUNER BY GERALD K. KITA STAKEI) TAB TERMINAL The present invention relates generally to a tab type terminal, and more particularly, to a tab type terminal having a shank portion for cooperation with an insertion tool.

According to the present invention, a tab according to the present invention is suited for insertion into a substrate, with teeth projecting laterally of the tab for gripping the substrate and preventing removal of the terminal therefrom. A pair of flanges form a hilt adjacent to the teeth for limiting insertion of the terminal within the substrate. The shank of the terminal is provided with a wire barrel and an insulation support, the wire barrel defining an aperture including a bearing surface for receiving the tool. The aperture and hilt cooperate to retain the terminal in registration on the tool during insertion.

It is therefore an objectof the present invention to provide an electrical terminal with a shank portion for locking registration with an insertion tool.

Another object of the present invention is to provide an electrical terminal, with a hilt for limiting insertion of the terminal within a substrate, and with teeth for gripping the substrate to prevent removal of the terminal therefrom.

Yet another object of the present invention is to provide an electrical terminal with a wire barrel and insulation support formed from a shank portion, the 'wire barrel further defining an aperture for registration with an insertion tool.

Other objects and many attendant advantages of the present invention will become apparent upon perusal of the following detaileddescription taken in conjunction with the accompanying drawing, wherein:

FIG. 1 is a perspective of a preferred embodiment of a terminal according to the present invention;

FIG. 2 is a fragmentary perspective of a preferred embodiment as shown in FIG. 1 terminated to a conductor wire and initially received on an insertion tool;

FIG. 3 is a fragmentary perspective of the terminal according to the present invention in full registration with an insertion tool as shown in FIG. 2;

FIG. 4 is an enlarged fragmentary elevation, with parts in section to illustrate the details thereof, and illustrating the terminal according to the present invention in full registration with an insertion tool and in partial registration within a substrate; and

FIG. 5 is an enlarged fragmentary elevation of the terminal according to the present invention fully inserted within a substrate with the insertion tool having been removed.

With more particular reference to the FIG. 1 of the drawing, there is shown generally at l a preferred embodiment of an electrical terminal according to the present invention. The terminal includes a generally rectangular tab 2 fabricated from a suitable electrically conductive metal. The end portion 4 includes laterally spaced chamfers 6 and 8 giving the end portion 4 a generally tapered configuration. The tab 2 has a pair of laterally spaced

side margins

10 and 12 having a plurality of laterally projecting serrations or

teeth

14 and 16, respectively. A pair of generally rectangular laterally projecting flanges l8 and are integral with the tab portion 2 and are respectively adjacent the

teeth

14 and 16. The terminal 1 is further provided with a shank portion 22 integral with and extending longitudinally of the tab portion 2. The shank portion 22 is provided with a generally centrally located rectangular aperture 24 having a planar bearing surface 26, extending laterally of the longitudinal axis of the tab 2 and disposed between the

flange portions

18 and 20. The aperture 24 is formed by an ear portion 28 which is integral with the shank portion 22 and is deformed in cantilever fashion out of the plane of the shank 22, thereby forming the aperture 24 and the bearing surface 26. More specifically, the ear portion 28 is deformed in cantilever fashion into a partially curled configuration defining a wire barrel. Another ear portion 30 integral with the shank 22 is also deformed in cantilever fashioninto a partially curled configuration in opposed relationship with respect to the ear portion 28. Together the

ear portions

28 and 30 cooperate to define an encircling wire barrel. The shank portion 22 is further provided with a generally elongated rectangular ear portion 32 which is deformed in cantilever fashion to a partially curled configuration defining an insulation support.

With reference to FIG. 5, taken in conjunction with FIG. 1, the terminal 1 is electrically and mechanically secured to a conductor wire 34 with the

ear portions

28 and 30 crimped thereto. The insulation support 32 partially encircles and is crimped over the insulation jacket 36 of the conductor wire 34. The terminal is also shown with its tab portion 2 staked or otherwise inserted into a substrate 38 which may comprise a card or board. The

flanges

18 and 20 engage the substrate 38 to provide a hilt and limit insertion of the tab 2. The teeth 14 and I6 register in the substrate 38 to prevent pull-out of the tab 2.

With reference to FIGS. 2 and 3, taken in conjunction with FIG. 4, the details of the insertion procedure and tooling will be explained in detail. As shown in FIG. 2, an insertion tool generally indicated at 40 includes a generally central driving head portion 42 with two laterally spaced

projecting alignment flanges

44 and 46. The end portion 48 of the tool 40 is recessed with respect to the projecting head portion 42 and the flanges 46. As shown in FIG. 2, the head portion 42 is initially inserted internally of the aperture 24 in the shank of the terminal, with the

lateral flanges

44 and 46 received in registration over the

flange portions

18 and 20, respectively. The terminal is then pivoted with respect to the tool 40 in a direction of the arrow generally indicated at 50 in order to fully register the tool 40 with the terminal 1. Such full'registration of the tool 40 is shown in FIG. 3, taken in conjunction with FIG. 4. With reference to FIG. 3, the

flange portions

18 and 20 will be received partially within the recessed end portion 48 of the tool 40 and in registration laterally against the projecting

flanges

44 and 46 of the tool 40. The tab 2 of the terminal will project longitudinally from the driving member 42 of the tool 40. The shank of the terminal will be in registration between and laterally supported by a pair of elongated laterally spaced

projections

52 and 54 provided on the tool 40.

As shown in FIG. 4, the projection 54 includes a recess portion 55 therethrough to laterally accept the insulation 36 of the conductor wire therethrough.

Further with reference to FIG. 4, the driving head por tion 42 of the tool is provided with a recessed anvil surface 56 which registers with the planar bearing surface 26 of the terminal. Thus, the head portion 42 is inserted within the aperture 26 of the terminal topartially overlie the shank portion 22 of the terminal, with the recessed anvil surface 56 in registration against the bearing surface 26 of the terminal. To forcibly insert the tab 2 within the substrate 38, the tab 2 is initially located partially within an aperture 58 of the substrate 38. The tool 40 is then forcibly driven by an operator in the direction of the arrow as shown at 60. A driving force will be transmitted through the anvil surface 56 of the tool head portion to forcibly insert the tab 2 into the substrate 38. As shown in FIG. 4, the anvil surface 56 projects from the recessed end portion 48 of the tool 40, thereby insuring that the driving force will be directed and transmitted along the longitudinal central axis of the tab 2. During insertion, the tool head 42 and the

tool flanges

44 and 46 will overlie the terminal to lockingly register the terminal to the tool. Additionally, the shank portion 22 of the tool will overlie a portion of the tool and be laterally supported between the

projections

52 and 54 of the tool.
