Description
ELECTRICAL CONNECTOR ELEMENTS Original Filed March 5, 1964 6 PC INVENTOR.
United States Patent 3,348,191 ELECTRICAL CONNECTOR ELEMENTS Robert John Kinkaid, New Cumberland, Pa., assignor to AMP Incorporated, Harrisburg, Pa. Continuation of application Ser. No. 349,565, Mar. 5,
1964. This application Feb. 3, 1967, Ser. No. 613,966 9 Claims. (Cl. 339-176) etc. The wire-receiving sections of the connector elements have to withstand a certain maximum force of insertion when applying conductors thereon. This force of insertion has been determined to be no less than thirty pounds.
Another problem has been the fact that the wire-receiving sections have been susceptible to torque. A further problem has been the proneness of the wire-receiving sections to short each other due to their close disposition.
It has been found that these electrical connector ele ments have not proved satisfactory because they are incapable of withstanding the maximum force of insertion of electrical leads on the wire-receiving sections thereof.
It is, therefore, a primary object of the present invention to provide electrical connector elements that when placed in a housing member are capable of withstanding more than the maximum insertion force when electrical leads are applied to the wire-receiving sections thereof.
It is another object of the present invention to provide electrical connector elements which are stable for all types of application of conductor means thereon.
A further object of the present invention is to provide 'electrical connector elements that may be used with any type of application of conductor means thereon.
An additional object of the present invention is the provision of the wire-receiving sections of the. connector elements being disposed in a manner to provide a more desirable thereto.
Other objects and attainments of the present invention will become apparent to those skilled in the art upon a disposition of the conductor means with respect reading of the following detailed description when taken in conjunction with the drawings in which there are shown and described illustrative embodiments of the invention;
it is to be understood, however, that these embodiments are not intended to be exhaustive nor limiting of the invention but are given for purposes of illustration and.
principles thereof and the manner of applying them in practical use so that they may modify them in various forms, each as may be best suited to the conditions of a particular use.
In the drawings:
FIGURE 1 is a perspective view of a housing member having the electrical connector elements disposed therein; FIGURE 2 is a cross-sectional view taken along lines 22 of FIGURE 1;
FIGURE 3 is a rear view of FIGURE 1 with the top row empty and the bottom row containing connector elements therein;
FIGURE 4 is a fragmentary perspective view of the connector elements during formation;
FIGURE 5 is a view taken along lines 55 of FIG- URE 4;
FIGURE 6 is a perspective view of a finished connector element ready for insertion in the housing member; and
FIGURE 7 is a perspective view of an alternative embodiment of the connector element.
Turning now to the drawings, there is shown in FIG- URES 1-3 a housing member H in which the electrical connector elements E are disposed. Housing member H is preferably molded from plastic material, such as, nylon, polypropylene, Bakelite, etc., and has a main body section 1, the front end of which contains a rectangularly shaped opening 2 in which a printed circuit board PC is to be disposed. Opening 2 extends to an inner rear wall 3 against which the edge of the printed circuit board engages to limit its movement within the opening. Each side and end of opening 2 has an inclined surface to facilitate the insertion of a printed circuit board thereinto.
Each side of opening 2 has a number of diametrical T-shaped passageways 4 which are evenly spaced and parallel with respect to each other. These T-shaped configurations become configurations of a cross at rear wall 3 and continue this configuration to where coaxial recesses 5 are located in the rear wall of the housing member. About midway between wall 3 and the inner end of recesses 5, the outer legs of the cross-shaped section of the passageways extending away from the longitudinal axis of the housing member are provided with abutting surfaces 6 as illustrated in FIGURE 2.
As can be seen from FIGURE 3, each recess 5 has surfaces 7, 8, 9 and 10 which extend from the inner end of the recess to the outer end thereof. Surfaces 7 and 9 are equally spaced from the vertical plane passing through the axis of the recess and are parallel thereto. Surfaces 8 and 10 are equally spaced from the horizontal plane passing through the recess axis and are parallel thereto.
' Projections 11 extend from the sides of housing member H and contain apertures 12 therethrough in order to define a means to secure the housing member to a mounting member (not shown). Of course, other means may be utilized to secure the housing member to a mounting member which are conventional in the art and need not be propounded.
Turning now to FIGURES 4-6, there is illustrated electrical connector element E to be inserted into passageways 4 of the housing member and secured therein. The electrical connector element comprises an engaging section 12, a wire-receiving section 13, and a securing section 14.
As illustrated in FIGURE 4, the'connector elements are preferably stamped from suitable metallic stock in a progressive die means which has the proper hardness to withstand the forces of insertion to be applied to wirereceiving section 13 when conductor means are applied and connected thereto, has the proper spring qualities to make excellent electrical connection with the circuit paths of the printed circuit board, as well as applying retentive pressure on the printed circuit board to maintain it in position and has the proper electrical conductivity to provide excellent electrical conductance. FIGURES 4 and 5 illustrate partial completion of the connector elements and FIGURE 6 illustrates the complete element.
As illustrated in FIGURE 5, one side of section 12 tapers from securing section 14 to a point about midway of section 12 and the remainder of this section then has the same thickness. The reason for this is to provide an excellent spring effect to section 12 in the form of a long cantilever beam.
As can be discerned from FIGURE 6, section 12 has a configuration similar to that of a section taken from the center of a spoon. Outer end 15 of section 12 is turned upwardly to facilitate engagement with the printed circuit board. Contact section 16 has a rearwardly inclined interconnects portions 19 square cross-sectional configuration.
surface as indicated in FIGURE 2. Both end and section 16, when in normal position in the housing member, are located out of the plane in which sections 13 and 14 are disposed. Sections 12 have sufiicient movement in their respective passageways to provide for normal tolerance when engaging any printed circuit board.
Edges 17 from end 15 to a point beyond contact section 16 toward securing section 14 are rounded so that .contact section 16 is slightly convex in this area which eliminates sharp edges that could gouge, scratch or scrape circuit path of the printed circuit board as well as providing excellent mechanical connection on the contact portion of the circuit paths.
Wire-receiving section 13 is rectangular in configuration. Outer end 18 is tapered to facilitate in one respect the insertion of the elements within passageways 4 of the housing member. The sides merge into section 14 with a slight radius.
Securing section 14 is divided into two portions, a stabilizing portion 19 and a locking portion 20. Portion 19 is rectangularly shaped and has projection 21 extending outwardly from the outer surface thereof. Portion 22 and 20 and has a width about one-half that of the widths of portions 19 and 20.
In assembly each connector element is inserted within a passageway 4 of the housing member with projection 21 coming to rest against abutting surface 6; then wirereceiving section 13 is rotated 90 against surfaces 7 and 9 in recess 5 which causes portion 22 to assume a twisted configuration between portions 19 and 20 which tightens element E in the passageway between surface 6 and recess 5 and completely secures it therewithin so as to withstand an insertion force in excess of the maximum amount. The surface of projection 21 in engagement with surface 6 is located about midway of portion 19 which provides a sufficient amount of portion 19 engaging the side sections of the cross configuration and extending toward section 12 to stabilize the connector element within its passageway.
As can be discerned, wire-receiving section 13 is normally disposed with respect to engaging section 12 which facilitates access to section 13 when applying a conductor means thereon as well as providing a more desirable disposition of the conductor means between the wire-receiving sections. While section 13 has been established as I being rotated 90 with respect to section 14, other angular dispositions between 0 and 90 may be effective in some aspects.
The conductor means can be applied to wire-receiving section 13 according to any of the ways conventional in the art, such as, welding, soldering, wire wrap, etc. When using wire wrap techniques, surfaces 7 and 9 prevent any torque from moving portion 20 out of position.
Another type of technique for the application of a conductor means to wire-receiving section 13 may be utilized in the manner disclosed in US. Patents 3,249,992 and 3,243,757, which apply an insertion force of about thirty pounds during the connecting operation.
FIGURE 7 illustrates an alternative embodiment of the connector element. In this embodiment, connector element E is similar to that of FIGURE 6 in every respect except that wire-receiving post or section 13 has a substantially Diametrical sides of section 13 have been subjected to a coining operation during formation of the connector element in order to form section 13 into its square-shaped configuration and to provide channels 23 (only one being shown) therein. After connector element E has been secured in housing member H in the same manner as connector element E, the sides containing channels 23 are disposed in planes 'normal to the plane containing contact engaging surface 16. The same techniques for applying conductor means to the post as outlined above, may be used. In case the techniques outlined in the above-mentioned US. patents were used, the bare wire portion of the conductor means would be disposed in one channel while the edges of the 4 connector elements disclosed therein would be disposed in the other channel. V As was pointed out hereinabove, section 12 from section 14 defines a long cantilever beam which provides excellent spring characteristics thereto in order to withstand numerous insertions and removals of printed circuit boards therein, provides a frictional fit connection for printed circuit boards to accept wide variations in thickness of the insulation body of the printed circuit board and to over come plastic creep to the insulation under load and provides mechanical stability under vibration or externally imposed stresses on the lead-in wires connected to sections 13 as well as excellent electrical continuity.
While the present invention has been disclosed in conjunction with a housing member containing only one opening in which two parallel rows of electrical'connector elements are disposed, it is obvious that the housing member may be provided with only a single row of electrical connector elements- Also, the housing member could be provided with a number of openings each of which contains at least one row of electrical connector elements instead of the single opening as illustrated.
It should be pointed out that the principles of the present invention are applicable to other types of electrical connector elements other than those with regard to printed circuit boards. The positive securing of electrical connector elements having a contact engaging configuration other than that disclosed can be utilized in accordance with connector elements used for other purwire-receiving sections 13 extending outwardly from each 7 end and secured in an opening of a mounting panel in the manner described above so as to receive conductor means on each wire-receiving section on both sides of the mounting panel. Other variations of the same theme can be enumerated but are deemed unnecessary as well as superfluous.
As can be discerned, there has been disclosed a unique and simple solution to providing electrical connector elements disposed in a mounting means which are capable of withstanding insertion forces on the wire-receiving sections thereof in excess of those conventionally utilized.
It will, therefore, be appreciated that the aforementioned and other desirable objects have been achieved; however, it should be emphasized that the particular embodiments of the invention, which are shown and described herein, are intended as merely, illustrated and not as restrictive of the invention.
