9 Claims. (Cl. 339-176) This application is a continuation of US. application Serial No. 198,645, filed May 29, 1962 and now abandoned.
This invention is concerned with connection of cables, wires, and other conductors to flat conductors such as printed circuit boards, flexible tape conductors, and other flat surfaces provided with conductors or other electrical components.
In making connections to flat conductors such as those of flexible tape cable, it has been standard practice to either individually connect each conductor by soldering and the like to terminals or to engage each conductor on one side of the cable by a resilient contact. In either case, the connections to each of the conductors of the flat cable must be disposed close to one another and can result in a definite close space limitation which can present the possibility of a short circuit or crosstalk between adjacent conductors. Thus, even though the conductors can be closely spaced in the flat cable, a limitation arises as to how close the connections to the cable can be made in a connector.
It is therefore one of the objects of the invention to provide an electrical connector for cable of the flexible tape type in which adequate spacing can be provided between the connection of a terminal member to each of the conductors of the cable.
It is another object of the invention to provide an electrical connector for cable of the flexible tape type in which all of the connections to the conductors of the cable can be disposed adjacent to one region of the cable and yet are adequately spaced from one another.
It is another object of the invention to provide an electrical connector for cable of the flexible tape type in which connections can be made to the conductors of the cable when it is folded.
In an embodiment of the invention the connector for cable of the flexible tape type comprises a body of insulating material having a slot extending inwardly from one face thereof. The connector further includes a support member about which the cable is adapted to be folded with the plurality of conductors of the cable exposed. The slot of the body member is adapted to receive the support member with the cable folded around it. In addition the body is provided with two parallel spaced apart rows of apertures which extend inwardly and intersect the slot. The apertures of each of the rows are spaced apart from one another with each row being disposed adjacent to a different one of the opposite sides of the slot. In addition, the apertures in one row are staggered with respect to the apertures in the other row. The connector also includes terminals disposed in the apertures which extend adjacent to the portion of the aperture which intersects the slot. With this arrangement the terminals of the rows can connect to the different alternate conductors of the cable when it is folded and inserted into the slot.
The invention comprises a self contained terminal connector having novel means for positioning a plurality of conductor terminals therein from one end face in predetermined relation and securely held therein for connection with flat conductors inserted into the connector from the other end face thereof.
The invention is provided with novel means for latching the conductor terminals therein in registered alignment, as above set forth, at the same time enabling the ready disengagement of said conductor terminals therefrom whenever desired. The connector is adapted to be readily secured to and removed from fiat conductors or components, providing positive and simple registry and electrical connection of the parts on assembly and enabling rapid and simple disassembly to be had when desired.
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 perspective, partly fragmentary view of a terminal connector embodying the invention, terminals being shown about to be inserted thereinto from one marginal edge thereof,
FIG. 2 is a fragmentary, elevational view, taken from the other marginal edge thereof, at line 22 of FIG. 1,
FIG. 3 is an enlarged vertical sectional view of the connector assembly, taken at line 33 of FIG. 5 and 3-3 of FIG. 1, with the flat conductor element 25 shown positioned therein and electrically connected with the conductor terminals therein,
FIG. 4 is a fragmentary elevational view of a tape conductor member shown secured to a holder which may be inserted into a connector of this invention,
FIG. 5 is a similar view, showing said holder inserted into the connector and removably connected thereto by latching means, taken at line 5-5 of FIG. 3,
FIG. 6 is an enlarged, partly sectional view of a conductor terminal 20 shown inserted and latched to the connector, taken at line 66 of FIG. 3, and
FIG. 7 is a partly fragmentary, longitudinal sectional view of the connector with the terminal therein shown about to be disengaged therefrom by a tool t.
As shown in the drawings, the terminal connector 10 of this invention comprises a member or body preferably made of dielectric material such as, for example, of plastic molded or otherwise formed to define a plate 12 having an end face 11. A section 13 of said plate (FIG. 7) from said end face 11 to a point 14 substantially short of the other end face 15 thereof, is provided with a series of parallel apertures 16, a wall 17 (FIG. 1) terminating in said one end face 11 of the plate, having the ends 18 of the series of apertures 16 extending therethrough. Walls 19 extend (FIG. 7) from the end 14 of the apertured section 13 to the said other end face 15 of plate 12.
Terminals 20 secured to cables, wires, or other conductors 21 (FIG. 1) are inserted through the apertures 18 of wall 17, said terminals have slotted or notched portions 22 or the like adapted to snap into latching engagement with the registering lock means such as bosses 23 of plate 12 aligned with the apertures 16 therein for latching the terminals 20 therein. The walls 19 terminate short of each other to define a space 35 therebetween (FIG. 2) to receive the conductor element 25. Terminals 20 preferably have flexible nosings 24 extending (when the terminals are so inserted into plate 12) along space 35 (FIG. 3) so that, upon insertion of the flat conductor element or cable of the flattened tape type (such as 25, FIGS. 5 and 3) to be connected to said terminals into Patented Oct. 4, 1966 said space 35 from the end face 15 thereof (FIG. 3) effective electrical connection will be made while the connected parts are fully enclosed and shielded.
The flat conductor element 25 may be carried by a holder 26 of any desired or convenient form, and may be made of two or more parts, for example, part 27 and support member 28 (FIGS. 3, 4) which may have interfitting or latching engagement; said flat conductor element 25 might be a printed circuit board or the like. The holder 26 may be provided with assembly means such as terminal flanges 29 (FIG. 4) for alignment with terminal flanges such as 30 of the plate 12 (FIGS. 1 and and means such as bolts 31 (FIG. 5) may secure the holder 26 and plate 12 together. The plate 12 may be provided with further registry and guiding means for the flexible nosings 24, such as for example, spaced bosses 33 intermediate which the nosings 24 register on insertion of the terminals 20 in plate 12 as above mentioned.
Apertures 16 have narrow portions 33 (FIG. 1) in which the nosings 24 slide on insertion of the terminals 20 in plate 12 (FIG. 1). Plate 12 is provided, from the end face 11 thereof with a second series of apertures 38 having narrow portions 36 corresponding with but inverted with relation to apertures 16 (FIGS. 1, 2, and 3) and apertures 38 are provided with bosses corresponding with the spaced bosses 23 and 33 of apertures 16 (FIG. 3) for registry of the second series of terminals 20a (FIG. 1) therewith. To remove a terminal from the plate 12,it is merely necessary to insert a tool t (FIG. 7) through the end face and above the terminal and lift, whereupon said terminal 20 may be withdrawn in the direction indicated by the arrow d (FIG. 7) out of plate 12.
As will be apparent to those in this art, from the disclosure herein, the invention may be used in connection with a holder 26 (FIG. 4) of my desired configuration, it being desirable for use thereof in connection with the connector 10 of this invention, only that a flat conductor element be presented for insertion into opening or slot (FIG. 2) of the body of insulating material or plate 12 for connection, thus with conductors 20 and 20a. Where, as shown in FIGS. 4 and 5, the holder 26 is used to hold flat conductor element 25 such as a flexible tape 40 or conductor ribbons 41 by scraping or baring the ends of said tape 40, the ribbons 41 (or selectively such of said ribbons as desired) may be exposed for connection with the conductors 20, 20a. The latter are (FIG. 1 and 2) held in plate 12 in staggered, spaced parallel relation. Thus, on assembly of the parts (FIG. 3) said conductors 20, 20a will be aligned with alternate conductors 41 of the flexible tape 40 so that connection may be made in this fashion with the predetermined desired conductor ribbons 41 therein. To this end the holder 26 may be provided with suitable markings 42 schematically illustrated in FIGS. 4 and 5 to facilitate identification of such of the conductors 21 as it is desired to connect with the conductor 40, which as above noted may engage alternate conductors 41.
The slot 35 may be polarized as noted at 43 (FIG. 2) so that a keying arrangement will be provided for insertion of the conductor element 25 into opening 43 only in the correct position.
