ELECTRICAL CONNECTOR APPARATUS Filed Oct. 18, 1962 INVENTOR. ARDEJID. KwHozs'szw BY f Arron/Er:
United States Patent 3,170,752 ELECTRICAL CONNECTOR APPARATUS Arden D. Van Horssen, Minneapolis, Minn., assignor to Nut-Line Industries, Inc., Minneapolis, Minn, a corporation of Minnesota 1 Filed Oct. 18, 1962,Ser. No. 231,461 3 Claims. (Cl. 339217) This invention relates to electrical connectors and more particularly to an improved electrical connector.
It is oftentimes necessary to mount a connector component or contact in an insert which may be rigid or resiliently yieldable. The component must be stable and immovable in the insert and provide a high degree of electrical continuity, but it is also desirable that the component be readily removable from the insert. though components of this general type have been known in the past, substantially all of such previously known.
components have been unduly complicated and costly.
With these comments in mind, it is to the elimination of these and other disadvantages to which my invention is concerned.
An object of my invention is to provide a new and improved insertable contact of simple and inexpensive construction and operation. 7
Another object of my invention is to provide a novel method of producing a socket contact with resilient spring fingers for receiving and positively engaging a pin contact of predetermined maximum size.
These and other objects and advantages of my invention will more fully appear from the following description made'in connection with the accompanying drawings whereinlike reference characters refer to the same or similar parts throughout the several views and in which:
FIG. 1 is a longitudinal section view through the assembled connector component;
FIG. 2 is a detail transverse section taken approximately at 22 in FIG. 1;
FIG. 3 is a detail transverse section View taken at approximately 3--3 in FIG. 1;
FIG. 4 is a detail transverse section view taken approxiinately at 4-4 in FIG. 1;
FIGS. 5, 6 and 7 show consecutive steps in. the formatioiiof the connector component and more specifically:
PG. 5 is an elevation view partly in section showing I a pie-f5: of tubing prior to the formation process;
PIC? is a longitudinal section view of the tubing at an intermediate stage of the formation process; and
FIG. 7 is an exploded elevation View, partly in section showing the elements prepared for final assembly.
One form of the invention is shown in the drawings and is described herein.
The electrical connector component is indicated in general by numeral 10 and is primarily adapted for mounting in a rigid or resilient insulatinginsert 11. The insert 11 has an aperture 12. therein and oppositely facing surfaces 13 and 14 at opposite ends of the aperture and around 7 the periphery thereof. The insert also has an enlarged opening 15 aligned with the aperture 12 and communicating therewith.
The connector component 10 includes an elongate body member 16 which is generally tubular in configuration and which is constructed of a conductive work-hardenable material such as beryllium copper. The body member 16 has a hardened socket contact-defining forward end portion 17 of a reduced diameter as compared to the intermediate portion 18; and the body member also has a tubular rear end portion 19. A plug or quantity of solder 20 or other flowable material is applied to the interior of the tubular rear portion 19 in sealed relation with the seal between the front and rear portions of the body member. I
The forward hardened end portion 17 is provided with a plurality of longitudinally extending linear cuts 21 spaced from each other around the periphery and defining a plurality of elongate resilient spring fingers .22, the outer or forward ends of which are segregated from each other so as to be adapted to converge in a forward direction with respect to each other. The innermost portions of the spring fingers are disposed within, and formed integrally of, the hardened forward portion 17.
The hardened forward end portion 17 has a metallic conductive and rigid shroud 23 thereon in tight-fitting encompassing relation. The rear sleeve portions 24 of the shroud has 'its rear end spun into an annular recess 25 in the hardened forward portion 17 of the body member 16 to thereby aflix the shroud 23 permanently in a predetermined position on the body member 16. The sleeve portion 24 has a forwardly converging conical inner surface 26 disposed along and engaging the innermost end portions 'of the spring fingers 22 and cause the spring fingers 22 to flex inwardly into convergent relation with each other. It will be noted that the outer ends of the spring fingers 22 are spaced transversely inwardly from the adjacent portion of the sleeve 24 so as to be permitted to fiex outwardly under the influence of a mating pin 27, shown in FIG. 1.
The shroud 23 also has an inwardly protruding annular flange or lip 23 disposed forwardly of the outer ends of the spring fingers 22 and with an inner peripheral surface or edge 29 disposed in substantial alignment with the outer. ends of the spring fingers so as to limit the size of mating pin allowed access into the socket contact. The
outer ends of the spring fingers have outwardly flaring 13 of the insert 11 and cooperates with the rear end 19 of the body member 16 in cooperative insert-clamping relation so as to hold the shank 32 and body member 16 in predetermined relation with respect to the insert.
A sealing ring 11a encompasses the body member 16 and seals against the insert 11 to prevent moisture migration along the exterior of the component 10 and through the insert.
The shank 32 has an enlarged head 35 at its forward end which defines a rearwardly facing annular shoulder surface 36. Surface 36'normally abuts rearwardly against the forward ends of resilient spring fingers 37 which converge in a forward direction along the shank and are flexible in an outward direction. TlE spring fingers 37 are mounted on, and formed integrally with, a mounting ring 38 which iscaptured in and aifixedly retained by a permanently deformed or crimped portion 39 of the tubular rear portion 19 of the body member. In the form shown, the portion 39 of the tubular rear end 19 is spun around the configuration of the ring 38 to hold the ring around its entire periphery against any fore-and-aft movemerit. 7 It will be noted that the shank 32 has a neck portion 4!) which carries a camming slide ring 41 movable forwardly along the shank and engageable with the spring fingers 37 to cam the spring fingers in an outward direction sufiiciently as to cause the spring fingers 37 to release the head 35 and permit the shank 32 to be withdrawn from the body member 18 and insert 11.
.The shank 32 also has an access groove 42 extending longitudinally and linearly along one side of the shank and through the flange 33 to open rearwardly to the exterior and to open forwardly adjacent the rear edge of camming ring 41. The groove 42 provides access for a tool such as a probe to be inserted inwardly along the groove into engagement with the ring 41 to urge the ring forwardly for camming the spring fingers 37 outwardly and causing the head 35 to be releasedf The shank 32 also has a wire terminal means 43 on the rear end thereof and in the form shown, comprises a solder pot 44 into which the end of a wire may be inserted and secured by soldering.
With reference now to FIGS. 5, 6 and 7, the novel process or method of forming the body member 18 is described. A length of tube 18 of work-hardenable material such as beryllium copper is used. During the initial stages the tubing 18 is in an annealed condition. During the processing of the tube 18' no heat treating is used. During the formation of the tube 18' it will be seen that in FIG. 6, the tubing has been spun so that the forward portion 17 has a reduced diameter. During the spinning to the reduced diameter, the forward portion 1'7 is work-hardened. The annular recess is shown completed in FIG. 6. The work-hardened portion 17' forwardly of the annular recess 25 has a cylindrical shape. During the spinning operation, the rear portion 19 is also spun to the configuration shown for receiving a shank therein. The rear end edge 19a remains in a cylindrical shape allowing subsequent assembly of the mounting ring 38 after the tubing 18 has been formed to the shape shown in FIG. 6. The workhardened forward end l7'-is completed by producing the cuts 21 longitudinally inwardly and linearly along and within the work-hardened forward end portion 17'. The shroud 23 is subsequently applied and the rear edge thereof is spun into the recess 25 as shown in FIG. 1. The spring fingers 37 and mounting ring 38 are subsequently inserted into the rear portion 19' which is subsequently spun inwardly at 39 so as to hold the ring 38 against fore-and-aft movement.
It has been found that producing the necessary resiliency in the spring fingers 22 by work-hardening the forward portion is satisfactory and completely comparable to hardening by heat treating. The hardening of the forward portion 17 by working the material and spinning localizes the hardening and allows additional working of the rear end portion 19 of the tube 18' so as to provide for attachment of the conductive shank and spring fingers37 thereto.
It will, of course, be understood that various changes may be made in the form, detail, arrangement and proportions of the parts without departing from the scope of my invention which consists in the matter described herein and set forth in the appended claims.
