Definitions

  • FIG. 5 ELECTRICAL CONNECTOR WITH BENT PIN CONTACT Filed July 9, 1964 FIG. 5
  • This invention relates generally to electrical connectors, and pertains more particularly to an electrical connector having a bent pin contact.
  • One object of the present invention is to provide an electrical connector having high current carrying capabilities even though fabricated in miniature form.
  • the demand for smaller and smaller connectors has introduced various problems and one of these problems is the establishment of a good electrical path when the two components comprising the connector are mated or engaged.
  • the invention has for an aim the provision of a bent or angled pin that is flexed by the socket contact or component when the two parts are coupled together.
  • Another object of the invention is to provide an elec trical connector having a hood surrounding the pin con tact so as to prevent damage to the pin contact and at the same time serve as a guide for the reception of the socket contact when engagement is made with the pin contact.
  • a further object is to provide an electrical connector that can be manufactured quite inexpensively which will be rugged in actual use and which is not likely to sepa rate due to vibrations and the like.
  • Yet another object of the invention is to provide an electrical connector that will not require adherence to close manufacturing tolerances.
  • Still another object of the invention is to provide an electrical connector having a hood which can be readily removed when circumstances so dictate.
  • the invention has for an aim the provision of a latching mechanism which permits the hood to be snapped into place, the latching mechanism normally retaining the hood in an encircling relationship with the pin contact but permitting the hood to be removed whenever it is desired to do so.
  • a further object of the invention is to provide an electrical connector having a. latching mechanism as referred to above which mechanism can be disengaged with a suitable implement but which will not inadvertently be disengaged by the socket component or contact.
  • FIGURE 1 is a side elevational view of one form the electrical connector can assume, the view showing the components before they are brought into engagement;
  • FIGURE 2 is a view similar to FIGURE 1 but with the components engaged with each other;
  • FIGURE 3 is a view generally similar to FIGURE 1 but showing a modified construction that the invention may constitute;
  • FIGURE 4 is a view corresponding generally to FIG- UR'E 2 but illustrating the connector of FIGURE 3 in its engaged position
  • FIGURE 5 is a sectional view of the pin component and encircling hood, an appropriate implement having been inserted into the hood from one end in order to effect the disengagement of the hood from the pin component.
  • FIG. 1 the electrical connector there shown which exemplifies the invention has been designated generally by the reference numeral 10.
  • a socket component 12 having a tubular configuration with a conventional solder pot 14 at one end and beveled entrance 16 at the other end.
  • a pin component 18 also having a conventional solder put 20.
  • the component 18 further includes a flange 22 and a cylindrical body 24. Projecting from the cylindrical body 24 is a resilient pin 26 having a rounded end 28 thereon.
  • a cylindrical hood 30 having a beveled enrtance end 32 which constitutes one surface of a circumferential rib 34.
  • the cylindrical hood 30 may be considered to be pressfitted over the cylindrical body 24, thereby providing a fixed attachment in this particular embodiment.
  • the hood 30 Inasmuch as the purpose of the hood 30 is to protect the bent pin 26, it can be made of metal or plastic. Stated somewhat differently, the hood is not intended to function as an electrically conductive member, although it could if it is desired that it do so.
  • the bent or angled pin 26 serves as one of two electrical contacts and therefore should be of metal in order to render it electrically conductive. Also, since the pin 26 is to be flexed, as will be presently described, it should possess good spring qualities. An appropriate copper alloy, such as beryllium copper, is satisfactory. Still further, the resilient pin 26 could be of Phosphor bronze or spring brass, or it could he steel.
  • the socket component since it functions as the second contact in the described connector, should also be of an appropriate metal and can be any one of those listed above, as well as still additional materials which would be satisfactory.
  • the outer diameter of the socket component or contact 12 is such as to pass through the entrance defined by the circumferential rib 34.
  • the rounded end 28 on the resilient pin 26 will normally lie quite close to the rib 34 on the hood 30 and is preferably in engagement therewith.
  • the resilient pin 26 will be flexed away from the rib 34 as can clearly be seen from FIGURE 2.
  • the bevel 32 facilitates the insertion of the socket component 12 and the thickness of the socket component is adequate to cause suflicient deflection of the resilient pin 26 so that the rounded end 28 thereafter pressurally bears or engages against the interior of the socket component, all ,as is clearly evident in FIGURE 2. Consequently, a good electrical path is established between the two components and the curvature is thereby enabled to carry a relatively high current even when fabricated on a miniaturized scale.
  • FIGURES 3-5 varies in certain respects from the embodiment of FIGURES 1 and 2. Consequently, the reference numeral 10a designates the connector shown in FIGURES 35.
  • the suffix a will be utilized for the purpose of distinguishing the parts, even though certain parts differ only slightly from those of the embodiment previously described and which has been given reference numeral 10.
  • the socket component 12a has a circumferential flange 36 extending about its outer surface for a purpose hereinafter explained.
  • the pin component 18a has a bent pin 26a formed with an integral collar 38 thereon.
  • the collar 38 has a shoulder at 40 and a tapered or conical cam surface at 42.
  • the cylindrical hood labeled 30a has an internal annular flange 44 provided with a central opening 46 of a size suflicient to allow passage of the collar 38 therethrough when the hood 30a is to be detached from the pin component 13a.
  • the embodiment ltla is constructed so that the hood 30a slidably circumscribes the body 24 rather than being fixedly secured thereto. It is the function of the collar 38 to latch the hood 30a in place.
  • the latched relationship is pictured in FIGURE 4 and it will be observed that the shoulder 40 is abutting against one side of the flange 44.
  • the pin 26a is first bent downwardly and then upwardly during its manufacture. Stated somewhat differently, the pin 26a has a bowed appearance when viewed from one side.
  • the rounded end on the pin 26a is in close proximity with the rib 34, this being the relationship also utilized in the embodiment 10.
  • the rounded end of the pin 26a will be deflected in the same manner that it is in the embodiment of FIG- URES 1 and 2. It will be noted that the deflection of the rounded end of the pin 26a will not unlatch the collar 38 from the flange 44.
  • a firm electrical engagement is derived by reason of the pressural action of the rounded end of the pin 26a against the interior of the socket component 12a.
  • an implement in the form of the tool 48 includes a cylindrical bushing portion 50 having one end 52 which cams against the surface 42. The other end of the tool 48 is provided with a head 54 by which the tool can be properly manipulated.
  • An electrical connector comprising:
  • said pin comopnent being bent in a direction to normally maintain its projection in engagement with said hood projection to prevent detachment of said hood from said pin component and also in a direction so that the end of said pin component that is to be received in said socket component lies adjacent one end of said hood,
  • said hood projection constitutes an annular flange having a centrally disposed opening
  • said pin component projection constitutes an integral collar having a shoulder which abuts said annular flange but of a size to pass through said centrally disposed opening.
  • An electrical connector in accordance with claim 3 including:
  • An electrical connector comprising:
