Definitions

  • Pin and socket connections of the type known to the art comprise a cylindrical pin which is secured, as by crimping, to a first wire and a socket having an axial bore which is secured to the second wire.
  • Disengageable electrical connections of this type are widely used, particularly for relatively small wires, i.e. AWG 16 or smaller, and ofier the advantages of compactness and a high degree of reliability.
  • AWG 16 AWG 16 or smaller
  • These connector assemblies often contain as many as 50 or 100 pins and sockets to permit the disengageable connection of 50 or 100 conductors by the manipulation of only the two dielectric blocks in which the pins and sockets are mounted.
  • the socket should have a closed entry, i.e. the entrance to the pin-receiving axial bore of the socket should be defined by a continuous rigid band of surrounding metal rather than by a split band.
  • the possibility of damage, such as might result from the attempted insertion of an oversized test probe is minimized and the life of the connection, in terms of the number of insertions and removals of the pin, is lengthened.
  • the force required to engage and disengage the pin and socket lie within relatively closely controlled and predetermined limits because, as explained above, pin and socket connector-s are often mounted in dielectric blocks with a relatively large number of pins and sockets in each block. Since the force required to engage and disengage these multiple connector blocks is largely determined by the engaging and disengaging force required for the individual pins and sockets, it follows that if this engaging force is high, the engaging and disengaging force required for the blocks will be extremely high and manual manipulation of the blocks may be impractical.
  • pin and socket connectors are manufactured by machining barstock using conventional screw machine techniques which permit close dimensional tolerances and which therefore yield closely fitting pins and sockets. It is common practice to form the sockets by axially boring the barstock and cutting or milling a slot therein.
  • a cantilever spring is secured to the socket in a manner such that it extends parallel to, and into, the slot so that the spring is resiliently stressed when the pin is inserted.
  • U.S. Patent 2,716,744 shows one type of machined socket having a separate spring of this type for imposing the contact pressure between the pin and socket.
  • these machined pin and socket connectors give good results and are highly satisfactory, however, they are relatively expensive as compared to connectors which are produced by die-stamping and die-forming of sheet metal stock. Furthermore, these machined pin and socket connectors cannot be manufactured in strip form, that is in the form of a continuous strip of connectors each joined to the other by the stock metal from which the strip was made. Connectors in strip form offer an advantage over loose-piece (i.e. individual) connectors in that a wide variety of crimping presses having feeding devices which automatically feed terminals in strip form is available so that the cost of applying a strip form connector onto a wire is usually less than the cost of applying a loose-piece connector.
  • the socket member comprises a formed elongated strip of metal having a U-shaped portion at one end which is adapted to be crimped onto the end of a wire.
  • the longitudinal edges of the remainder of the strip are bent relatively towards each other and joined together, as by welding or mechanical fastening, to form an axial pin-receiving socket.
  • Contact pressure for an inserted pin is established by means of a spring finger which is integral with the socket member and which extends obliquely of the socket axis towards a slot in the socket.
  • a tongue extends from the mouth of the socket and is reversely bent rearwardly over this finger and then obliquely away from the socket.
  • This tongue serves the dual function of retaining the socket against axial movement in a dielectric block and also on its underside serves as a bearing surface and support for the end portion of the spring finger.
  • the pin member in accordance with the preferred embodiment is formed in substantially the same manner as the socket, that is by bending the longitudinal edges of a metal strip towards each other.
  • the nose portion of this pin which functions as the electrical contacting portion, is rolled into the form of a cylinder and an intermediate portion is provided from which is struck a finger similar to the contact spring finger of the socket.
  • This finger on the pin functions as a retainer to lock the pin in a dielectric block.
  • FIGURE 1 is a perspective view of a socket member in accordance with the invention.
  • FIGURE 2 is a side view of the socket member of FIGURE 1;
  • FIGURE 3 is a view similar to FIGURE 2 but showing the socket member positioned in a dielectric block and illustrating the function of the retaining spring;
  • FIGURE 4 is a view similar to FIGURE 3 but showing the positions of the parts when a mating pin is inserted into the socket;
  • FIGURE 5 is a cross sectional view showing a complete pin and socket set with the parts in engagement with each other;
  • FIGURE 6 is a side view of a connector pin member in accordance with the invention.
  • FIGURE 7 is a plan view illustrating the sheet metal blank from which the socket member of FIGURE 1 is formed;
  • FIGURE 8 is a plan view of the sheet metal blank from which the pin member of FIGURE 6 is formed;
  • FIGURE 9 is a perspective view of a dielectric block having openings to receive pins or sockets in accordance with the invention.
  • FIGURE 10 is a perspective cut away view of a portion of a dielectric block showing the form of the openings
  • FIGURE ll is a view taken along the line 11--11 of FIGURE 5;
  • FIGURE 12 is a perspective view of a stamping and forming progression showing the manner in which the socket members in strip form are manufactured.
  • a socket member 2 has at one end thereof an insulation crimp portion 4 and a wire crimp portion 6.
  • the sidewalls of these crimp portions are bent relatively towards each other and then towards the insulation and the strands of the electrical conductor to establish an electrical and mechanical connection therewith.
  • a web 8 extends along the top of the socket, as viewed in FIGURE 1, and sidewalls 10 extend from the sides of this web downwardly.
  • These sidewalls curve towards each other in their lower portions and their edges 12 are bent outwardly so that their internal surfaces are in abutting relationship and are welded as shown at 14 to form a stiffening rib which extends axially along the socket.
  • Sidewalls 10 thus define a pin-receiving axial cavity which is semi-cylindrical in its lower portions, as viewed in FIGURE 1, but which has substantially parallel and straight sidewalls in its upper portions adjacent the web.
  • the radius R of the semi-cylindrical portion is substantially equal to the distance from the web to the center of the semi-cylindrical portion so that a substantially cylindrical pin can be inserted into the cavity.
  • the rib formed by the edges 12 has an extension 16 adjacent crimped portion 6 which functions as a stop when the socket is inserted into a dielectric block.
  • a resilient finger 18 is formed from the intermediate section of web 8 by severing this web from the sidewalls along its longitudinal edges and severing along a line extending transversely across the web adjacent the open pin-receiving end of the socket.
  • this finger which functions as a contact spring, does not extend entirely up to and against the front portion 9 of the web but a short section of the web is punched out during the forming so that an appreciable gap is left between the front end 22 of the finger and the web portion 9.
  • this finger is bent downwardly at 19 and into the cavity in the socket while its extreme end 22 is reversely bent so that it extends outwardly beyond the socket.
  • a tongue 28 is integral with the web at the frontal portion thereof and is reversely bent at 30 so that it extends rearwardly towards the crimped portion of the socket as shown in FIGURE 2.
  • this tongue slopes downwardly towards the axis of the socket and then obliquely away from the axis of the socket. While the end 22 of the finger and the portion 32 of the tongue may normally be in contact with each other, as shown in FIGURE 2, as a general rule, neither of these parts is stressed to any appreciable extent by the other when the end of tongue 23 is free as shown in FIGURE 2. In other words, the finger is substantially in its normal position as shown in FIGURE 2.
  • a preferred type of dielectric block 34 has parallel faces 35, 37 and a plurality of cavities 36 each of which is shaped to receive a socket or a pin as described below.
  • each cavity has a rearward section opening into face 37 (FIG- URE 10) of substantially circular cross section excepting for a fiat wall 38, an intermediate section of which slopes obliquely towards the axis of the opening.
  • a frusto-conical transition section 44 is provided intermediate the ends of the cavity and extends about halfway around the cavity wall opposite fiat wall 38. This flat wall ends at an abrupt shoulder 40 which is disposed on the rearward side of frusto-conical surface 44.
  • the right hand portion of the cavity as viewed in FIGURES 3 and 11 is of substantially uniform cross section throughout its length and has a semi-cylindrical wall 52 adjoining the frusto-conical surface and a pair of diametrically opposed ledges 42 on each side of wall section 52.
  • a pair of flat parallel sidewalls 48 extend from these ledges to a flat wall 46 which extends from shoulder 40.
  • sidewalls 48 extend rearwardly beyond shoulder 40 and then diverge at 49 to define a guide section which aligns the socket during insertion.
  • block 34 may provide extension 39 on its sides having openings 41 for the reception of a suitable means for securing two blocks together and/or for polarizing the two blocks to ensure that they are assembled to each other in proper orientation.
  • a suitable means for securing two blocks together and/or for polarizing the two blocks to ensure that they are assembled to each other in proper orientation For example, it is known to provide pins in some of these openings to ensure polarization and machine screws and nuts to clamp a pair of blocks together.
  • blocks of the type shown usually are provided with a metallic housing, the block 34 having a shoulder 43 for cooperation with such a housing.
  • this finger can be considered to be a cantilever beam extending from the body of the connector socket and having its free end 22 supported against substantial radial movement away from the axis of the socket. Some radial movement of this free end may take place but such movement will be limited by the underside of the tongue. The free end is, however, free to move axially, relative to the socket axis, over the underside of tongue 28. The amount of such movement will be relatively slight; however, the fact that this end is free to move is an important factor in maintaining reproducibility of the insertion and extraction force for the pin.
  • FIGURE 6 there is shown a connector pin in accordance with the invention which is also formed from sheet metal in the same manner as the socket.
  • the connector pin comprises a cylindrical contact nose portion 54 at one end which is adapted to enter the socket cavity, a frusto-conical transition section 58, and an intermediate portion 59 which has a cross-sectional configuration similar to the intermediate section of the socket.
  • this intermediate section has a substantially fiat web 62 from which parallel sidewalls eX- tend adjacent thereto and the sidewalls in turn are curved towards each other and their edges are outwardly bent at 60 and welded together to form a longitudinal stiffening rib.
  • this rib is enlarged as shown at 61 to form a stop for the purpose of locating the pin in a dielectric block.
  • This intermediate section also provides laterally extending stabilizing fins 64 on each side of the web and the web itself is severed along its edges and bent outwardly as shown at 66 to form a resilient finger.
  • This finger functions as a retaining spring for retaining the pin in the dielectric block cavity and, like the corresponding tongue 28 of the socket, it extends rearwardly towards the crimped portion in order to serve this function.
  • the pin of FIGURE 6 differs from the socket in that the retaining spring 66- in the pin is formed from the web while in the socket the retaining spring is formed by means of the tongue which before bending extends axially in front of the socket.
  • the lefthand portion of the pin as viewed in FIGURE 6 comprises a wire crimp portion 68 of U-shaped cross section having a flat web as with the socket and an insulation support crimp portion 70 having a similar cross sectional configuration.
  • These U-shaped ferrule forming portions are crimped onto the end of a wire in the same manner as the corresponding portions of the socket. It will be apparent from the drawing that the intermediate and lefthand end portions (the ends which are secured to the wires) of the socket and of the pin are similar in shape and dimension.
  • the dielectric block 34 can accommodate either pins or sockets and this is an advantageous feature of the invention in that the number of dif ferent parts (i.e. pins, sockets dielectric blocks) which are required for a multiple connector assembly is thereby reduced.
  • FIGURES 7 and 8 show the punched out sheet metal blanks from which sockets and pins in accordance with the invention are formed.
  • the structural features of these blanks are identified by the same reference numerals as those used in FIGURES 1-6 in the foregoing description of the finished parts, the reference numerals of FIG- URES 7 and 8 being differentiated by prime marks in the interest of clarity.
  • FIGURE 12 it will be seen that in the preferred method of forming sockets in accordance with the invention, the blanks are stamped from strip metal in side-by-side parallel relationship to each other 'with each blank connected by means of a slug or connecting piece 72 to a carrier strip 74 having evenly spaced perforations 7 6 therein to facilitate feeding of the strip to an automatic crimping machine.
  • the blank for the pin member can be formed in substantially the same manner as is shown in FIGURE 12 excepting that the foreward extension (56' in FIGURE 8) is rolled about the longitudinal axis of the blank to form the cylindrical contact nose of the pin.
  • the end of this extension is scalloped so that a substantially hemispherical leading end on this contact nose results.
  • a salient overall advantage of the invention is that it permits the manufacture of pin and socket type connectors by die stamping of sheet metal and connectors manufactured in this manner can be produced more cheaply than by automatic screw machine methods. Furthermore, as previously noted, stamped sheet metal connectors can be produced in strip form and strip form connectors can usually be applied to wires more easily than loose-piece connectors by reason of the fact that strip connectors can be automatically fed to the crimping tool or press with relative ease.
  • strip connectors can be automatically fed to the crimping tool or press with relative ease.
  • cantilever contact springs must be designed such that they will withstand the deflection to which they will be subjected upon insertion of the pin without the imposition of stresses higher than the yield point of the material.
  • the contact spring should be capable of deflecting about 0.004 inch without exceeding its yield point and the contact spring should impose the desired contact pressure on the pin when it is deflected by this amount. It would be impractical to design the spring for a deflection of less than about 0.004 inch for a 0.050 inch diameter pin by reason of the tolerances in the pin diameter for which allowances must be made.
  • the spring has been provided as a separate piece which is asembled to the connector by clinching or some similar securing method.
  • This scheme of having the spring as a separate piece has a distinct advantage in that the spring can be made of a metal having better spring properties than the connector itself.
  • brass or phosphor bronze are excellent metals for the socket itself since they are easily formed, have sufficiently good electrical conductivity and strength and can be crimped onto wire ends with relative ease.
  • these metals are not desirable spring materials for the cantilever springs of sockets of the instant type by reason of the fact that their yield strengths are not sufliciently high.
  • the yield strength of phosphor bronze is about 75,000 p.s.i.
  • the spring may be formed of a material having a relatively lower yield strength than in these prior art devices by reason of the fact that this spring is a supported cantilever rather than a simple cantilever.
  • the end of the spring normally bears against the underside of the tongue or is positioned very close to this tongue and this end is, moreover free to move longitudinally relative to the surface of the tongue.
  • the contact spring is flexed in the manner of a cantilever beam which is freely supported at its end.
  • Recourse to beam stress formulae will show that a supported cantilever beam of a given length and cross section will withstand a considerably higher load without exceeding its yield point than will a similar beam without end support.
  • the beam load in the instant invention is, of course, the load imposed by a pin and the reaction forces imposed by the spring on the pin to establish the electrical connection.
  • a supported cantilever beam of a given material and given dimensions will withstand a load 5.75 times greater than an identical unsupported beam assuming that the unsupported beam is loaded at its end and the supported beam is loaded at 0.61 I.
  • the tongue is completely rigid in the disclosed embodiment.
  • some fiexurc will be imparted to the tongue via the end of the contact spring.
  • the end of the contact spring is not free to move radially and since its radial movement is substantially limited, it is stressed in the manner of a supported cantilever in the disclosed embodiment.
  • the dielectric block is advantageously of molded phenolic or other plastic. Molded plastic parts can be made to very close dimensional tolerances with ease and the dimensions of the openings in the block are, in the disclosed embodiment, held Within precisely predetermined limits.
  • the end of the tongue is flexed towards the socket axis as shown in FIGURES 3 and 4 so that after insertion, this tongue occupies a precisely predetermined position with relation to the location of the contact spring.
  • contact spring is integral with the connector (i.e. formed to the same strip) the contact surface between the spring and the pin is fully effective as an electrically conducting interface.
  • the spring is a separate piece, its contact with the tongue is not fully effective because an additional interface, or electrical barrier, is presented Where the contact spring is mechanically secured to the socket.
  • a sheet metal electrical connecting device formed from an elongated strip having an end portion of U-shaped cross section crimpable onto a conductor and a tubular adjoining portion, the longitudinal edges of said strip in said tubular adjoining portion being radially outwardly bent and secured together to form an axially extending rib, said rib being of stepped profile to form a stop intermediate its ends for engagement with a portion of a housing member into which said connecting device is adapted to be inserted, a spring extending lengthwise of said connector struck out from said tubular adjoining portion on the opposite side from said rib, and longitudinal stabilizing ears on each side of said spring, said ears comprising outwardly bent portions of said strip adjacent to said spring, said ears being adapted to engage complementary surfaces in said housing thereby to prevent movement of said connecting device.
