Definitions

  • the socket comprises a stamped and formed cylindrical body portion which is adapted to receive the pin at one end thereof and which has ears extending from its other end obliquely inwardly with respect to the axis of the body portion.
  • the body portion of the socket has an axially extending open seam and is contained relatively snugly within a cylindrical cavity in an insulating housing.
  • the cars are relatively rigid and are rigidly connected to the body portion so that when the pin is inserted into the socket, the ears are moved relatively outwardly, however, because of the fact that the ears are rigid and nonfiexible, the body portion of the socket is forced to elastically deform to accommodate the movement of the ears. Because of the fact that the body portion of the socket is circumferentially confined in the cavity, the body portion deforms along its length and functions as a spring means maintaining electrical contact between the socket and the leading end of the inserted pin.
  • This invention relates to pin and socket type electrical connections and particularly to pin and socket connecting devices intended for use in terminal junction systems.
  • the herein disclosed embodiment of the invention is particularly intended for use in a terminal junction system of a general type disclosed in the above identified U.S. Pat. 3,456,321, however, it will be apparent that the principles of the invention can be employed in alternative terminal junction systems or in alternative types of electrical connecting devices.
  • the terminal junction system disclosed in U.S. Pat. 3,456,321 comprises a plurality of individual modules contained in a suitable mounting frame. Each module has mounted therein a plurality of contact sockets, each of which is adapted to receive a contact pin having a radially extending integral collar intermediate its ends. Two or more sockets are electrically connected to each other in each module so that upon insertion of the contact pins, the wires to which the pins are connected are electrically connected to each other.
  • the individual contact sockets for a terminal junction system are advantageously provided with a means for engaging an inserted pin and retaining it in the socket against accidental removal and additionally should have a means for establishing a contact pressure at the interface between the socket and the pin thereby to insure the achievement of a stable, low resistance electrical contact between the parts.
  • the length of the contact sockets is advanta- United States Patent geously held to a minimum dimension.
  • a contact socket of the pin and socket connection comprises a stamped informed cylindrical body portion which is adapted to receive a contact pin at one end thereof and which has contact ears extending obliquely inwardly, with respect to the axis of the body portion, from its other end.
  • the contact ears are relatively rigid and are rigidly connected to the body portion so that they are resistant to flexure when the pin is inserted.
  • the cylindrical body portion is contained in a cylindrical cavity in an insulating housing, the diameter of this cavity being substantially equal to the outside diameter of the body portion of the socket so that circumferential expansion of the body portion of the socket is prevented when the pin is inserted.
  • the socket must, nonetheless, be deformed when the pin is inserted and such deformation takes place along the length of the body portion of the socket.
  • sections of the body portion are bowed inwardly as a result of the stresses imposed on the ears and the resulting movement of the ears away from the axis of the socket.
  • the entire cylindrical body portion of the socket functions as a contact spring maintaining the ears in intimate contact with the leading end of the pin thereby insuring a stable low resistance electrical connection.
  • FIG. 1 is a perspective view of a progression showing the manner in which contact sockets in accordance with the invention are formed from strip metal;
  • FIG. 2 is a perspective view of a short section of stock metal of the type used in the manufacture of the strip of FIG. 1;

  • FIG. 10 is a view similar to FIG. 9 but showing the appearance of the socket after insertion of the pin and particularly illustrating the resilient deformation of the socket.
  • FIG. 11 is a sectional side view taken along the lines 1111 of FIG. 9 of an individual socket mounted in a cavity in a housing.
  • FIG. 12 is a view similar to FIG. 11 but illustrating the appearance of the socket after insertion of the pin.
  • contact sockets 2 in accordance with the invention are advantageously manufactured in the form of continuous strip 4 comprising a pair of parallel spaced apart carrier strips 6, 8.
  • the carrier strips are connected to each other by integral rungs 10 and the individual sockets are connected to the carrier strip on each side of each run by means of laterally extending connecting strips 11.
  • the individual sockets are stamped and formed from the stock material on each side of the carrier strips 6, 8 and the spacing between the individual sockets is therefore determined by the diameters of the sockets. This spacing is somewhat greater than the spacing ordinarily required in the terminal junction system and the pitch of the strip, that is the spacing between adjacent sockets on the strip, must be shortened prior to mounting the sockets in the module housings. Such shortening of the strip is achieved by folding the sections of the carrier strips 6 and 8 which extend between adjacent sockets as shown at 12 and 14, FIG. 3.
  • a strip of contact sockets in the condition shown in FIG. 3, that is after the carrier strips 6, 8 have been folded as shown at 12 and 14, can be used in a feedthrough terminal junction module.
  • terminal junction modules of this type are used where it is desired to connect wires extending axially towards each other.
  • the connecting strips 11 can be bent as indicated at 16 (FIG. 4) to locate the individual contact sockets 2 in side-by-side parallel relationship and facing in a common direction.
  • Strips of contact sockets of the type shown in FIG. 4 are used in the so-called feed-to modules as shown in FIGS. 6-8 to form disengageable electrical connections among wires extending parallel to each other towards a common location.
  • the instant invention is directed to the structural features of the individual contact sockets 2 and it should be understood that sockets of this type can be used in a variety of connecting devices other than terminal junction systems.
  • the structure of the feed-to terminal junction module of FIGS. 6-8 is briefly described below for the purpose of illustrating a specific use of a socket contact and an electrical connection in accordance with the instant invention. It will be understood that the advantages of the invention in terminal junction systems dis cussed below are achieved in feed-through terminal junction modules as well as feed-to modules of the type illustrated.
  • Each feed-to terminal junction module 18 comprises a generally rectangular insulating housing 20 of a suitable firm plastic material such as diallylphthalate having a plurality of cavities 22 extending from its upper side 23 to its lower side 21.
  • FIG. 6 shows a typical module in an inverted position in order to illustrate the structure of the lower side of the module and the manner in which the terminal strip is placedin the module.
  • Recesses 26, 28 are provided on the lower side 21 of the housing section 20 and clusters of connected sockets are inserted through these recesses to locate the individual contact sockets in the cavities 22.
  • the recess 26 contains 6 cavities 22 and a section of strip 25 to which six sockets are attached is mounted in this portion of the housing.
  • the recess 28 contains two individual cavities 22 and two individual sockets connected to each other as shown at 27 are inserted into the cavities which open into the recess 28.
  • a suitable lower cover plate 30 is cemented to the lower side 21 of the housing to retain the sections of terminal in the housing section 20.
  • a sealing block 24 of relatively soft material is mounted against the upper side 23 of the housing section 20 and has passageways extending therethrough which communicate with the individual cavities 22 in the housing.
  • the individual contact pins 32 can then be moved downwardly, as viewed in FIGS. 7 and 8, through openings 29, the sealing block 24 and into the individual contact sockets contained in the housing section 20.
  • the particular module illustrated in FIGS. 6-8- provides a common connection for six individual conductors on its right hand side as viewed in FIGS. 68 and provides additionally a common connection for two individual conductors on its left hand side.
  • modules of this type are made in a variety of configurations capable of forming common connections among varying numbers of conductors.
  • the so-called feed-through modules in which strip having aligned sockets of the type shown in FIG. 3 is mounted, can be provided to interconnect varying numbers of conductors.
  • the individual contact sockets 2 each comprise a cylindrical body portion 36 having an open seam 38.
  • Retaining lances 40 are struck from the wall of the body portion on each side of the seam and extend obliquely inwardly toward the axis of the body portion, these retaining lances being adapted to bear against an inserted pin and retain the pin in the socket in a manner described below.
  • Bars 42 are integral with the body portion 36 on each side of the open seam and extend obliquely inwardly with respect to the axis of the body portion, these cars being connected to the body portion along arcuate lines 50 which render the ears resistant to flexure when the pin is in serted.
  • Contact sockets in accordance with the invention are advantageously manufactured from strip material 44 which comprises a relatively wide layer 46 of thin sheet stock having good spring properties such as beryllium copper.
  • a layer of high conductivity metal 48 such as pure copper, is bonded to the surface of the layer 46 and located mid way between the edges of the layer of beryllium copper stock.
  • the individual contact pins 32 have cylindrical bodies 52 with Wire receiving openings at their rearward ends to receive the stripped ends of wires 34, the pins being crimped to the wires by any suitable electrical crimp as shown at 54.
  • each pin is provided with a circumferential collar 58 which defines a rearwardly facing shoulder 62 and a forwardly facing shoulder 60.
  • a conical surface 56 is provided which is adapted to engage the inner surfaces of the ears 42 and to move the ears outwardly during insertion.
  • the diameter of the collar 54 is substantially equal to, and slightly less than, the inside diameter of the body portion 36 of the socket so that the pin can be inserted into the socket as illustrated in FIGS.
  • the previously identified inwardly directed lances 40 are sprung outwardly while the pin is being inserted and, after completion of the inserting operation are lodged behind the collar 58 and against the rearwardly facing shoulder 62 of this collar. These lances thus prevent accidental removal of the pin from the socket although an individual pin can be removed from a socket by the use of a suitable extraction tool which is adapted to surround the conductor 34 and the body portion 52 of the pin. Such extraction tools can be moved along the axis of the pin until they bias the retaining lances 40 outwardly thereby permitting the pin and the extraction tool to be removed from the socket.
  • the cavities 22 in which the sockets are contained have a shoulder 64, adjacent to the side 23 of the housing, which prevents movement of the individual sockets leftwardly in FIG. 9 with respect to the module housing.
  • the cavities also have a diameter which is substantially equal to, and slightly greater than, the outside diameter of the sockets so that the sockets are prevented from expanding circumferentially when the pins are inserted.
  • Contact pressure between the inner surfaces of the connecting strip 11 and the leading end of the pin 32 is achieved when the pin is inserted by virtue of the fact that the leading end of the pin forces the ears to move relatively outwardly and away from the axis of the socket as illustrated in FIGS. 10 and 12.
  • the ears are rigid along their lengths by virtue of the fact that they are formed from a double layer of material and additionally by virtue of the fact that they are connected to the body portion of the socket along an arcuate, rather than a straight line, transition zone 50. These transitions between the ears and the body portion of the socket are thus highly resistant to flexure and should not be confused with a simple straight line transition which would permit the ears to act like simple cantilevers, that is, to be flexed outwardly.
  • the body portion has a tendency to flex inwardly, particularly in the zones indicated at 70 between the open seam 38 and the lances 40.
  • These sections, at least, of the body portion appear to function as elliptic or semi-elliptic springs resiliently biasing the inner surfaces of the ears against the surface of the leading end of the pin. The ears, in turn, bias the lower side of the pin (as viewed in FIG.
  • the nature of the deformation also causes the seam 38 in the body portion to be opened somewhat immediately adjacent to the ears 42 and to be closed intermediate the ends of the body portion.
  • the right hand or rearward end of the seam may open slightly as a result of the stresses imposed by the insertion of the pin or may have the same width after insertion as it has before insertion.
  • the body portion assumes a slighly oval configuration after insertion of the pin with the major axis of the oval extending transversely of the open seam 38 on the upper side of the body portion. This effect is illustrated best in FIG. 12 where it can be seen that the upper edge of the right hand side of the body portion has been drawn away from the shoulder 64 in the housing while the edge on each side of the seam is firmly against this shoulder, see FIG. 10.
  • an essential feature of the invention is that the body portion 36 of the socket deforms along its length when the pin is inserted and performs the function of a contact spring maintaining the inner surfaces of the ears 42 against the surface of the inserted pin.
  • the ears bias the leading end of the contact pin against the surface of the connecting strip 11.
  • the surface of this connecting strip comprises the high conductivity metal 48 of the strip and extends continuously to the other contact sockets of the cluster, By virtue of this arrangement, a low resistance conducting path is provided between contact sockets in the module.
  • the ears themselves function as contact means to some extent in that they are resiliently biased against the pin, however, the conducting path from the ears of one socket to the other socket or sockets of the cluster must extend through the body portion of the socket and in the disclosed embodiment, this body portion is of a material having a relatively lower conductivity (because it is of beryllium copper) than the conductivity of the connecting section 11. If the socket were to be made from homogeneous stock metal, rather than the laminated stock of FIG. 2, the electrical function of the ears would be of greater significance than in the disclosed embodiment.
  • the precise mechanism by means of which the contact spring effect is achieved may vary somewhat from the mechanism discussed above which pertains to the particular embodiment of the invention herein disclosed.
  • the variations in the mechanism may depend upon, for example, the thickness of the stock metal 46, the length of the body portion, and the amount of movement of the ears brought about by the leading end of the inserted pin. It is quite possible that a combination of effects will result when the pin is inserted and there may be some outward deflection of the ears relative to the body portion of the socket after the body portion itself has been resiliently deformed as shown in FIGS. 10 and 12.
  • the salient feature of the invention that is, the use of the body portion of the socket as a contact spring, can be achieved. in a variety of specific socket designs so long as the ears, or their equivalents, remain resistant to flexure when the pin is inserted and function to transmit stresses to the body portion which in turn should be capable of resiliently deforming so that it can perform its function as a spring means.
  • An electrical contact socket adapted to receive a contact pin at one end thereof, said socket comprising a hollow cylindrical body portion having pin engaging means extending inwardly from its other end and having conductor means extending from said other end, said socket being contained, and relatively closely confined against circumferential expansion, in a cavity in an insulating housing, said pin engaging means being rigidly attached to said body portion and said body portion being resiliently deforamable inwardly towards the axis of said body portion along its length upon relative movement of said pin engaging means away from the axis of said body portion whereby, upon insertion of said contact pin, said pin engaging means is moved relatively away from the axis of said body portion and said body portion is resiliently deformed along its length, said body portion functioning as a contact spring urging said pin engaging means against said pin and said pin engaging means urging said pin against said conductor means.
  • a contact socket as set forth in claim 1 including integral retaining lance means struck from the wall of said body portion and extending towards said other end, said lance means being adapted to engage said contact pin to prevent removal thereof from said socket.
  • Disengageable electrical connecting means comprising a contact socket and a contact pin disposed in said socket, said socket being contained in a cavity in an in- 8 sulating housing and comprising a cylindrical body portion having an axially extending open seam, said cavity confining said body portion against substantial circumferential expansion,
  • ear means rigidly attached to the end of said body portion which is adjacent to the end of said pin, said ear means extending obliquely inwardly with respect to the axis of said body portion and being held in an outwardly displaced position by said contactpin,
  • said body portion being resiliently inwardly bowed along its length by stresses transmitted from said ear means whereby said body portion functions as a contact spring and maintains said ear means against said pin.
