Definitions

  • An electrical connector comprises an insulating housing containing pairs of contact springs. the springs of each pair normally engaging one another. The springs of the pairs can be cummed apart by insulating plugs inserted through holes in the housing to isolate subscribers and to allow line testing by test tabs inserted through liurther holes in the housing to engage the contact springs.
  • This invention relates to electrical connectors and more particularly to electrical connectors having normally engaged contacts disposed in a housing which are capable of being cammed apart.
  • Main distribution frames in automatic telephone exchanges are used for the cross-connection of incoming (topographic side) wire pairs with the central office (numerical side) terminals of the exchange, breaking the cross-connections for the purpose of testing for network faults, isolation of individual subscribers from the exchange, tapping lines for purposes of listening in and the connection of spare incoming wire pairs.
  • a conventional main distribution frame consists of two distributing frames known asthe horizontal side" frame and the vertical side frame. n the horizontal side frame, test and break jacks are mounted in horizontal rows, the terminals of one side of each break jack being connected in numerical sequence to line finders of the exchange. On the vertical side frame, terminal blocks are mounted in vertical rows, the terminals of one side of each of these blocks being connected to incoming wire pairs.
  • Each break jack has four contact springs mounted in an insulating housing to provide two normally closed contacts, twenty or more such break jacks being assembled in a block.
  • the distance between the rows must be such as to permit maintenance staff to manually connect and disconnect the jumper wires.
  • a break jack assembly for an automatic telephone exchange distribution frame comprises an insulating housing in which are arranged pairs of contact springs, each contact spring having a terminal for connection to an external electrical lead, contact surfaces of the contact springs of each pair normally engaging one another electrically to connect the terminals of the pair of contact springs, and is characterized in that the contact springs of the pair are separable from one another electrically to disconnect these terminals by inserting an insulating plug through a first hole in the housing to engage between the contact springs so as to move the contact surfaces of the contact springs apart from one another, each contact spring having a contact portion for engagement by an electrically conductive tab inserted through a second hole in the housing to be resiliently engaged by the contact portion of the contact spring.
  • the tab may conveniently be engaged between the contact portion of the contact spring and a wall of the housing.
  • a further object is that the contact springs of each pair conveniently cooperate to define a recess for receiving the insulating plug so that the insulating plug does not engage the contact surfaces of the contact springs.
  • contact springs of each pair may be guided by ribs on the internal wall of the housing.
  • a still further object is that the insulating plug and the tabs may be carried by a common plug unit so that the contact springs are simultaneously disconnected from one another and each contact spring of the pair is connected to one of the tabs for line-testing purposes.
  • a main distribution frame for an automatic telephone exchange may be formed by mounting a row of break jack assemblies according to the invention upon a supporting panel or frame with the housings of the assembly on one side of the panel or frame and the terminals of the contact springs, which are insulated from the panel or frame where the panel or frame is of metal, projecting from the other side of the panel or frame, a jumper wire being connected to one terminal of each contact spring pair, for example, by wrapping the bared end of the jumper wire about the terminal which is conveniently formed by an electrical post, or by connecting the jumper wires to the terminal by an electrical clip, by means for example, of a hand tool or an automatic magnetic tape controlled coordinate-connecting machine.
  • Each jumper wire conveniently connects one of the terminals to one end of a further post, which extends through an insulating member, the other end of the further post being connected to an incoming wire.
  • the other terminal of each pair of contact springs is connected to a numerical cable of the exchange.
  • break jack assemblies are readily accessible for isolation and test purposes from above the panel.
  • FIG. I is a front plan view of a break jack assembly according to the invention.
  • FIG. 2 is a top plan view of the assembly
  • FIG. 3 is an enlarged cross-sectional view of the assembly showing a test plug unit in the course of being mated with the break jack assembly, the test plug unit being shown only schematically;
  • FIG. 4 is a similar view to that of FIG. 3 but showing the test plug unit fully mated with the break jack assembly;
  • FIG. 5 is an enlarged rear elevational view of a contact spring of the break jack assembly, prior to being mounted in the assembly;
  • FIG. 6 is a side elevational view of the contact spring of FIG.
  • FIG. 7 is a front elevational view of the test plug unit
  • FIG. 9 is a front plan view of the test plug unit.
  • Pairs of apertures 18 extend through the base wall 16, each pair of apertures I8 communicating with one of the compartments of the housing 1.
  • Each aperture 18 has a portion 20 of increased cross-sectional area providing a shoulder 22.
  • the base wall 116 has a central frustoconical section portion 24 projecting into each of the compartments and from which extend ribs 26, spaced from oneanother longitudinally of the housing 1 and terminating closely adjacent the cover plate 4. There are two ribs 26 in each compartment, only one of these ribs being shown (FIGS. 3 and 4).
  • a pair of oppositely oriented contact elements 27 is disposed and each of which comprises a terminal post 28 (only six of these posts are shown in FIG. 2), an intermediate portion 30 from which has been stamped an obliquely extending locking tongue 32 engaging one of the shoulders 22, and a contact spring 34 extending from the opposite end of the post 28 to the intermediate portion 30.
  • the contact spring 34 is divided longitudinally into two portions by a central through slot 36 which extends between points a and b on the contact spring, as indicated in FIGS. and 6.
  • Each contact spring 34 has a portion 38 converging upwardly (as seen in FIG. 3) towards the portion 38 of the other contact spring of the pair.
  • the portion 38 is a rectilinearportion of the contact spring providing a flat contact surface 40 substantially parallel to the post 28.
  • the contact spring has a portion 42 for cooperation with the portion 42 of the other contact spring of the pair to provide a recess 44 (FIG. 3), the portion 42 having a pair of laterally extending opposed ears 43.
  • each contact spring 38 has a bight 46 from which extends a contact arm 48 having a bowed contact portion 50.
  • each contact element 27 In the normal position (FIG. 3) of each contact element 27, the contact surface 40 of each element 27 engages the contact surface 40 of the other contact element of the pair.
  • the crest of the bowed portion 50 of each contact element engages one of the sidewalls 17 of the housing 1 to maintain contact surfaces 40 in springable engagement with one another, and each lug 43 of the contact element is guided by one of the ribs 26 thus ensuring that the portion 43 cooperates with the portion 43 of the other contact element of the pair to define the recess 44.
  • Each pair of elements 27 accordingly forms a normally closed switch.
  • the test plug unit which is generally referenced 52, comprises an insulating body 54 from which project four electrically conductive tabs 56, in quadrangular array each connected within the body 54 by means (not shown), for example by solder or crimping ferrules, to one wire of a four-wire multiple-conductor test cable 58.
  • the body 54 has serrated finger grips 60 at its upper end.
  • Formed integrally with the body 54 and projecting between the tabs 56 are two insulating plug members 62 spanned by and formed integrally with a rib 64 for engagement in one of the slots 12 of the cover plate 4 and being disposed unsymmetrically with respect to the longitudinal axes of the members 62.
  • the plug members 62 have chamfered free ends 65.
  • a series of the break jack assemblies described above are secured to an insulating panel or frame (not shown) by screws or bolts passed through the holes 3 of the lugs 2 so that the housing 1 extends from one side of the panel, the posts 28 of the contact elements 27 extending from the opposite side of the panel or frame where the panel or frame is of metal, the posts 28 are insulated from the panel or frame.
