Definitions

  • the present invention relates generally to an electrical connector module, and more particularly, to an electrical connector module designed primarily for use in the communications or data transmission industries to provide access to and electrically connect one or more of a plurality of electrical circuits or leads to one or more other such circuits or leads.
  • circuit access members such as connector panels or terminal blocks. These panels and terminal blocks provide for termination of the incoming and outgoing leads at the rear face of the panel or terminal block. This termination is normally accomplished by conventional techniques such as wire wrap, soldering or the like.
  • the front side of such panel or terminal block provides means for electrically accessing each of the individual incoming or outgoing leads via a connector element. In some cases, this access was provided by a wire wrap pin with the connections between such pins being made via the conventional wire wrap or soldering process.
  • connectors were developed which eliminated the need for patch cords of fixed lengths. These connectors provided means for directly connecting one end of a jumper or connecting wire to a first connector element and means for directly connecting the opposite end of the jumper or connecting wire to a second connector. A tool was also provided for use with these connectors to connect the jumper wire to the connector elements and to sever excess wire after the connection had been made. With these connectors, a single spool of wire could be used to make the various connections desired, thus eliminating the need for maintaining an inventory of patch cords. Two such connectors were used for this purpose are identified in U.S. Patent Nos. 3,518,618 and 4,283,105. Although these connectors were satisfactory in many respects, they inherently embodied several limitations.
  • An electrical connector module including the features set forth in the first part of claim 1 is known from US patent No. 3,976,350.
  • a housing is provided with surfaces which define passageway for receiving contact fingers of a contact element in a close fit, with only limited flexing being permitted near the tips of the fingers to ensure that the fingers will pierce the insulation of an insulated wire inserted between them. Due to this close fit, the point at which the conducting core of the wire is held in contacting engagement by the fingers, and the point where the insulation of the wire is gripped by a slot provided in the housing, lie close together.
  • the invention provides an electrical connector module as defined in claim 1 and a split cylinder type connector as defined in claim 18.
  • the connector element which contacts the core of the wire is spaced from the housing which holds the insulation of the wire, the two functions (mechanical retention of the wire and electrical connection) are clearly separated at all conditions that may occur in use of the module. Due to the disposition of the wire gripping slot of a rectangular housing, the spacing between the two points of engagement can be made rather larger without increasing the overall space required by the individual connector module. Further, since the wire gripping slots are formed on the diagonal of the rectangular housing, comparatively large wire gripping surfaces and, accordingly, gripping forces are available.
  • the electrical connector module of the present invention is adapted for use in an access member such as a quick cross connect panel or in a terminal block to electrically connect various electrical leads or circuits with certain other electrical leads or circuits.
  • certain of these leads may be referred to as incoming leads while others are often referred to as outgoing leads.
  • these incoming and outgoing leads may represent communication circuits such as telephone lines or various types of data transmission circuits.
  • the electrical connector module of the present invention is utilized to patch or cross connect such lines to accommodate growth of telephone usage, changes in telephone number, relocation of users, etc.
  • Reference numeral 10 in Figure 1 represents a quick cross connect panel adapted for use as described above.
  • This panel 10 includes a relatively flat panel member 11 and a plurality of electrical connector modules 12. As illustrated in Figure 1, the modules 12 are arranged in side-by-side adjacent relationship with respect to one another in an array. As will be described in greater detail below, the modules 12 may be color coded to identify various types of incoming or outgoing leads or circuits to distinguish those from others. Each of the individual electrical connector modules 1.2 is inserted into and retained within a hole or opening 13 in the panel member 11. In Figure 1 a portion of the modules 12 have been removed from the panel 11 to show these holes 13. Reference is next made to Figures 2, 3, 4 and 5 showing the specific details of the electrical connector module of the present invention. As illustrated specifically in Fig. 2, each of the modules 12 is intended for positioning in side-by-side relationship with respect to another.
  • Each module 12 includes a housing 16 constructed of a non-conductive material and a centrally position split cylinder connector member 18. As illustrated best in Figure 3, the housing 16 includes a central portion 25, a pair of upwardly extendiing side wall portions 19 and 20 and a pair of downwardly extending side wall retaining sections 26 and 27.
  • the centrally positioned portion 25 is defined by four flat side wall surfaces extending at right angles with respect to the plane of the panel member 11. In the preferred embodiment, the dimensions of each side wall of the central portion is the same, thus giving the portion 25 a square cross sectional configuration.
  • the side walls of the central portion 25 are closely adjacent to a corresponding side wall of an adjacent module and a lower surface of the portion 25 engages the top surface of the panel 11.
  • the portion 25 includes a cylindrical opening 31 ( Figure 6) to facilitate insertion of the connector 18.
  • Each of the upwardly extending side wall portions 19 and 20 is integrally formed with the central section 25 and each includes a pair of integrally joined side wall sections disposed at right angles with respect to each other. Each of these side wall sections extends upwardly in the same plane as a corresponding side wall of the central portion 25. As illustrated, a portion of the corner 23 joining adjacent side wall sections of the side wall sections 19 and 20 is cut away, so that its outer edge is spaced inwardly from the outer corner of the central section 25. As shown in Figure 2, these cut away corners 23 are recessed to provide an opening at the corners between diagonally adjacent modules 12 ( Figure 2). This opening provides exit space for jumper or connecting wires 14 (Figure 1) which extend through the wire gripping slot 22.
  • Adjacent edges of the side wall sections 19 and 20 are spaced from each other to define a pair of slots or grooves 21 and 22.
  • the slot 21 is normally wider than the slot 22 and has a width which is at least as wide as the outer diameter of the insulated connector wire 14 ( Figures 1 and 22) used to make the electrical connection between desired leads.
  • the slot 22 has a width which is less than the exterior diameter of the jumper wire and functions as a strain relief wire gripping slot to grip such wire and prevent the same from being inadvertently pulled from the connector 18.
  • the slot 22 includes an enlarged portion 24 at the top whose width approximates the outside diameter of the jumper wire. This enlarged portion assists in guiding the jumper wire into and aligning the same with respect to the strain relief slot 22.
  • the slot 22 is formed in the diagonal of the housing 16. This provides several advantages. First, it enables a plurality of modules 12 to be arranged in an array. Secondly, because the respective edges of the slot are greater on the diagonal, the wire gripping surface force of the slot 22 is greater. Thirdly, positioning the slot 22 on the diagonal permits a larger range of jumper wires because of the longer side wall portions adjacent to the slot 22.
  • the depth of the slot 21 is less than the slot 22.
  • the wire gripping slot 22 extends downwardly to the top portion of the central section 25, while the wire exit slot 21 which is wider than the insulated jumper wire stops short of the section 25 and extends downwardly only to the shoulder portion 33.
  • this shoulder portion 33 causes the free, cut off end of the jumper wire to be bent upwardly as the wire is forced into the module, thereby facilitating easy removal of the portion of the wire which is severed.
  • Each of the retaining sections 26 and 27 of the housing 16 includes a pair of side wall portions which are integrally joined and disposed at right angles with respect to each other.
  • the side wall portions of the retaining sections 26 and 27 are generally parallel to the side walls of the central section 25, are spaced inwardly therefrom and extend downwardly from the section 25 in a direction opposite that of the side walls 19 and 20.
  • the side walls of the sections 26 and 27 and the side walls of the central section 25 are joined by a shoulder 43 extending at right angles with respect to the side walls of the sections 25, 26 and 27.
  • the retaining sections 26 and 27 are spaced from each other by the slots 29, 29 ( Figures 3 and 5) to permit the sections 26 and 27 to be moved inwardly toward each other during insertion of the housing 16 into the panel 11.
  • Each of the retaining sections 26 and 27 includes a retaining rib or edge 28 extending outwardly about its lower periphery for engagement with a portion of the panel 11 to prevent the housing 16 from being removed from the panel 11 after it has been inserted.
  • each of the retaining sections 26 and 27 includes an elongated groove 32 to assist in retaining the split cylinder connector 18 within the housing 16.
  • Each of the grooves 32 includes a shoulder portion 34 adapted for engagement by a retaining tine 45 extending outwardly from the connector 18.
  • this shoulder portion 34 is beveled at a negative angle to insure engagement between the end of the tine 45 and the shoulder 34 to prevent inadvertent removal of the connector 18 from the housing 16.
  • the included angle "A" formed between the beveled shoulder 34 and the interior surface 31 is less than 90 degrees.
  • the internal surface of the retaining members 26 and 27 has a generally cylindrical configuration extending from the surface 31 of the section 25 to permit a relatively tight fit between such surface and the outer cylindrical surface of the split cylinder connector 18.
  • this tight fitting relationship keeps the retaining ribs 28, 28 engaged with the bottom surface of the panel 11 and precludes inadvertent removal of the module 12 from the panel 11.
  • the split cylinder connector 18, which is best illustrated with reference to Figures 2-8, includes a generally cylindrical upper portion 35, a generally cylindrical lower portion 39 and an enlarged collar section 46.
  • the upper cylindrical section 35 includes an elongated slot 42 for piercing the insulation of an insulated wire 14 and for gripping and making electrical contact with such wire.
  • a pair of guide sections 36, 36 are integrally formed with the slot 42 and are positioned at the top end of the cylindrical section 35.
  • a cutting edge 38 is also disposed near the top edge of the upper cylinder 35 and opposite the slot 42. As will be described in greater detail during a discussion of the operation of the module 12, the edge 38 functions to sever the wire 14 during insertion into the upper cylindrical portion 35. In the preferred embodiment, the edge 38 is disposed above the interaction between the sections 36, 36 and the slot 42 to permit the wire 14 to be severed prior to insertion into the slot 42.
  • the lower cylindrical section 39 also includes an elongated slot 44 for piercing the insulation of the jumper wire and for gripping and making electrical contact with such wire.
  • a pair of entrance or guide edges 40, 40 are positioned at the bottom edge of the cylinder 39 and are integrally formed with the opposing edges of the slot 44.
  • a cutting edge 41 similar to the edge 38 is also formed in the bottom surface of the cylindrical member 39.
  • a pair of flared retention tines 45, 45 are cut from opposing side portions of the cylindrical portion 39 and are prestressed so that they are disposed outwardly from the outer cylindrical surface of the section 39 as illustrated in Figures 3 and 8. As shown best in Figures 3 and 9, each of the tines 45, 45 is curved or coined so as to substantially conform to the curved inner surface of the grooves 32 ( Figure 5). This increases the surface area engageable with the shoulder 34 ( Figure 11) and improves the retaining ability of the tines 45, 45.
  • the split cylinder connector 18 also includes an enlarged peripheral rib or collar section 46 adapted for engagement with the seating surface 30 ( Figures 4, 6 and 7) of the central section 25 when the connector 18 is inserted therein. As shown best in Figures 3, 4, 6, 7 and 8, a partial cross slit 50 is made in the connector 18 immediately below the collar 46. The collar 46 is then split and the corners flared out as illustrated by the reference numerals 48, 48 in Figures 4, 6, 7 and 8. In the preferred embodiment, the collar 46 is split in the same general location as the slot 42. To facilitate the flaring of the edges 48, 48 a vertical cut 49 ( Figures 7 and 10) is also made on opposite sides of the collar 46. With the above structure, a significantly increased bearing area is provided for engagement with the seating section 30.
  • the flared out portions 48, 48 provide a corresponding bottom seating surface 47 for engagement with this supporting surface 30. It has been found that this particular arrangement provides a substantially improved support and stability for the connector 18 when retained within the housing 16. As seen best in Figure 6, the distance between the bottom seating surface 47, 47 and the top ends of the ribs 45, 45 should be approximately the same distance as between the seating surface 30 and the beveled shoulder portions 34, 34.
  • Figure 12 shows a plurality of adjacent modules 12 illustrating the manner in which a jumper wire 14 is inserted and retained within one of the modules, while Figure 13 shows a wire 53 inserted and retained within the connector portion 39 on the back side of the panel 11.
  • the wire is inserted with a tool similar to that illustrated in Figures 17, 18 and 19.
  • Such tool includes a handle 60, an elongated intermediate section 61 and an end section shown in Figures 18 and 19.
  • the end section includes an open portion 68 defined by the peripheral side wall 62 and the centrally positioned post 66.
  • Each of the corners 65 of the side wall 62 is angled to fit within the interior of the housing 16 ( Figure 3).
  • a pair of diametrically opposed recessed portions 64, 64 are provided at two of the corners 65 to receive the wire 14 during the insertion process.
  • a section of the wire is laid across the top surface of the module 12 such that a portion of the wire contacts both the cut-off edge 38 and the guide edges 36, 36 in the area of the slot 42.
  • the enlarged portion 24 and the slot 21 assists in this alignment.
  • the portion of the wire 14 to be severed is that portion engaging the cutting edge 38 while the portion making electrical contact with the connector 18 is that portion engaging the edges 36, 36.
  • the tool is then appropriately positioned over the wire 14 with the recessed portions 64, 64 ( Figure 19) aligned with the wire and the side wall 62 disposed between the inner surface of the housing side walls 19 and 20 and the outer surface of the cylindrical portion 39 of the connector 18.
  • a downward force then causes the wire 14 to be inserted into the module 12 to the position illustrated in Figure 12.
  • the wire 14 is cut by the cutting edge 38 while the portion of the wire engaging the guide surfaces 36, 36 is forced between the contact slot 42.
  • the edges of the slot 42 pierce the insulation of the wire and make electrical contact with the conductor portion 17.
  • the tool also causes a portion of the wire to be forced between the wire gripping or strain relief slot 22, thus causing the operative end of the wire 14 to be retained by the slot 22 in the manner illustrated in Figure 12.
  • This end of the wire 14 then extends upwardly in the area between diagonally adjacent modules 12 formed by the recessed edges 23, 23 for connection to a second module.
  • the cut off end of the wire is also forced downwardly by the tool; however, because of the shoulder portion 33 ( Figure 7), the cut off end of the wire is forced upwardly. This facilitates easy manual removal of the wire end which has been severed.
  • Figure 13 shows a wire 53 connected with the back side of the panel member 11.
  • This wire 53 is connected in a manner similar to the connection on the front side of the panel by using the tool illustrated in Figures 17 to 19.
  • the wire is laid across the connector cylinder 39 so that. the portions of the wire 53 engage the edge 41 and the edges 40, 40 in the area of the slot 44.
  • the tool is then appropriately aligned and an insertion force is exerted. The force severs the portion of the wire engaging the edge 41 and cause the edges of the slot 44 to pierce the insulation of the wire 53 and contact the conductive portion 57.
  • Figures 14 and 15 illustrate an alternate embodiment of the electrical connector module of the present invention. Specifically, Figure 14 illustrates an alternate embodiment of a single module, while Figure 15 illustrates an array of a plurality of such modules.
  • the structure of Figures 14 and 15 include a pair of insulated side walls 51, 51 which are separated at their adjacent corner by a wire gripping slot 52. Similar to the preferred embodiment described above, the slot 52 is positioned on the diagonal of a module having a square cross sectional configuration.
  • the opposite ends of each of the side walls 51, 51 includes a recessed surface 58, 58 to allow for the modules to be positioned in an array as illustrated in Figure 15. These recessed corners provide sufficient room for the jumper wire to loop upwardly after insertion into the wire gripping slot 52.
  • the alternate embodiment of the module illustrated in Figures 14 and 15 also includes a split cylinder connector 55.
  • the diameter of the element 55 can be larger than the connector 18 shown in Figure 3 because of the absence of the second side wall sections of the side walls 51, 51.
  • the center of the connector cylinder 55 is off-set toward the corner of the module opposite the slot 52.
  • a larger connector 55 can be used without decreasing the density of the connectors for a given area.
  • Figure 16 illustrates an alternate embodiment of a split cylinder connector.
  • the connector 18 ( Figure 3) of the preferred embodiment includes a double ended connector having a split cylinder type of connecting means at both ends.

  • the assembly of the module of the present invention can be described as follows.
  • a panel 10 of the type illustrated in Figure 1 a plurality of the insulated housing elements are first inserted into the holes 13 in the panel member 11.
  • these housings can be colour coded and arranged for insertion into the panel to facilitate such identification.
  • the individual housings in an array can also be oriented so that the jumper wires from the modules will all extend in a particular direction. For example, if modules in one array are to be connected with modules in a second array, the modules may be oriented such that the jumper wires, when inserted, extend in a general direction toward the outer array.
  • the insertion can be done either with the tool illustrated in Figures 17-19 or any other similar tool with an elongated end to fit within the housing side walls.
  • the lower portion of the housing, specifically the retaining sections 26 and 27, are forced into the hole 13 in the panel 11 until the retaining edges 28, 28 snap outwardly into engagement with the lower surface of the panel 11 as illustrated in Figures 6 and 7.
  • the split cylinder connector 18 is then inserted into the cylindrical opening 31 within the housing 16. This insertion can also be accomplished with the tool of Figures 17-19 or other appropriate means.
  • the connector 18 is forced into the central opening of the housing 16 until the retaining tines 45 snap outwardly into engagement with the retaining grooves 32, 32 and the retaining shoulder portions 34, 34 as illustrated in Figures 6 and 11.
  • the module is then totally installed.
  • a plurality or set of wires or leads 53 representing a plurality of circuits are first connected to the ends of the connector 18 positioned on the backside of the panel 11 ( Figure 1). After these connections have been made, the ends of the connectors on the top side or front face of the connector panel 11 can be connected. This includes connecting insulated jumper wires 14 from one connector to another, thereby connecting the respective leads associated with those connectors. It should be noted that several wires can be connected to each of the connector elements on the top side of the panel, thus facilitating the connection of one lead to a plurality of other leads.
