BUSH A T TORNEV United States Patent 3,339,719 TERMINAL TAPE Harold J. Bush, Matawan, N.J., assignor to The Thomas & Betts Co. Inc., Elizabeth, N.J., a corporation of New Jersey Filed Oct. 12, 1965, Ser. No. 495,065 16 Claims. (Cl. 206-56) This invention relates to a terminal tape or belt for mounting a plurality of terminals in predetermined spaced relation, to facilitate securing them to conductors, for compressing, assembly or other processing operations.
The terminal tape of the invention incorporates novel structural features, such that the terminals may be initially readily inserted therein and will be held in positive, predetermined position throughout the processing operations and readily released therefrom on completion thereof.
A further feature of the invention is to provide a terminal tape having novel means for registration of the conductors with terminals positioned in the tape, to assure full insertion of each conductor into a terminal and for inspection and verification of registration.
The drawings, illustrating procedures and devices useful in carrying out the invention, and the description below, are exemplary only of the invention, which shall be deemed to cover all other devices and procedures coming within the scope and purview of the appended claims.
In the drawings, wherein similar reference characters indicate like parts:
FIG. 1 is a fragmentary top plan view of a terminal tape embodying the invention,
FIG. 2 is a transverse, sectional view, taken at line 22 of FIG. 1,
FIG. 3 is a transverse sectional view, taken at line 33 of FIG. 1, of the terminal tape, with a terminal shown positioned therein, and a conductor shown about to be inserted into the ferrule end thereof,
FIG. 4 is a similar view, showing the conductor fully inserted into the terminal, and
FIG. 5 is a schematic, perspective view of the terminal tape, inserted intermediate compression or other assembly members.
As shown in the drawings, the terminal tape of this invention comprises a web 10, which may be fabricated of suitable polyvinyl or other plastic or convenient material, to the dimensions and degree of flexibility preferred, and of the length desired, to receive and display thereon a plurality of terminals 13. The tape may be initially made and supplied in specific or continuous lengths, in roll or other form, for feeding, as schematically noted in FIG. 5, intermediate processing members 14, 15, which may be compression dies, manually or automatically actuated, as desired. The tape may be advanced by frictional or mechanical means or by pawls, sprockets, or the like, engaging tape drive openings 16 (FIG. 1) along one edge of the tape.
Pursuant to the invention, a plurality of slots 17 are provided in the tape and so spaced therealong as to provide the desired spacing for the terminals 13. The slots 17 are disposed at 25 or other desired angle relative to the longitudinal edges of the tape, and are preferably U- shaped, with the legs 18, 19 thereof directed toward the longitudinal edge 12 of the tape and away from apertures 20 formed in the tape for reception of ferrule portions 21 of the terminals 13. The tape may receive terminals 13 of any desired or convenient form, with ferrule portions 21 and lug ends 22 connected to the ferrule portions by throat portions 23.
The lug end 22 of a terminal may be readily inserted through the slot 17 (slot ends 18, 19 facilitating positioning in the slot) to dispose the throat portion 23 beneath the tape (FIG. 1) with the ferrule portion 21 straddling 3,339,719 Patented Sept. 5, 1967 aperture 20. The latter is provided with doubly stepped portions, viz., first recessed portion 24 directed toward the slot 17 and the narrower, second, recess or stepped portion 25, closer to slot 17. Web 10 may be further provided with depressed grooves or V-shaped portions 26 terminating in tabs 30, proportioned to preferably extend into the apertures 20, to snap into (FIG. 3) the ferrules 21 on positioning of the latter in apertures 20 and to register the ferrules with the first recess 24 (FIG. 1). The V- shaped portions 26 of belt 10 are medially registered with the apertures 20 and aligned with the second recess or stepped portions 25 in the apertures 20.
On insertion (FIG. 3) of a conductor 27 into a termi nal 13, it is initially registered and guided by the depressed V-shaped portion 26 for entry into the ferrule portion 21 of the terminal; upon full (FIG. 4) insertion of the conductor 27 into the terminal, the end 28 of the conductor (for example, the end of a wire or cable) will abut and home against the second recess 25 and the conductor insulation end 27 registers within the ferrule portion 21. Thus, registration of the end 28 of the conductor with the more constricted portion 25 of aperture 20 is a positive operation; the operator will sense that the conductor has been fully inserted, by abutment of the conductor with the second recess 25 of the tape aperture 20, in preparation for the compression or other processing procedure. The tape may, for example, then be advanced to a station wherein (FIG. 5) compression dies 14, 15 may be closed on the assembly and the tape then advanced to remove the completed assembly.
While the foregoing disclosure of exemplary embodiments is made in accordance with the patent statutes, it is to be understood that the invention is not limited thereto or thereby, the inventive scope being defined in the appended claims.
'1. A tape for positioning terminals having conductor receiving ferrule portions therein, said tape having spaced parallel longitudinal edges defining therebetween an elongated web portion, apertures provided in said web portion for receiving the ferrule portions, constricted portions formed in said apertures, the parts being so pro portioned that on insertion of a conductor in and through the fer-rule, the conductor will abut the constricted portion of the aperture, to thereby align the conductor in the terminal.
2. In a terminal tape as set forth in claim 1, said terminals having lug ends, slots in said web portion for positioning the lug ends of the terminals therein, to dispose the terminals in spaced parallel relation in the tape.
3. In a terminal tape as set forth in claim 2, said apertures in said web portion being disposed in spaced relation to the slots and aligned therewith.
4. In a terminal tape as set forth in claim 2, said slots being angularly disposed relative to the longitudinal edges of the tape.
5. In a terminal tape as set forth in claim 2, said slots being disposed in a plane at an acute angle to the longitudinal edges of the tape.
6. In a terminal tape as set forth in claim 2, said slots being disposed in a plane at an angle of approximately 25 to the longitudinal edges of the tape.
