  • the electrical jack of the present invention which is of the type which is commonly used for telephones or communications," includes a pair of relatively L shaped frame members each including a first, second and third sections (reference numerals 10, ll, 12 and 14, l5, 16 respectively).
  • each of the first sections and 14 of the frame members is an elongated relatively rectangular shaped section which forms one leg of the L shaped frame member and which contains means in the form of the jack sleeves l8 and the jack plug 27 shown in FIG. 2 for electrically connecting a portion of the jack with a terminal (not shown) remote from the jack.
  • Each of the first sections 10 and 14 further includes an aperture 19 for connecting the jack of the present invention to an electrical jack panel by appropriate connecting means (not shown).
  • each of the third sections 12 and 16 are a plurality of jack springs 21 and 22, connecting springs 24 and insulating blocks 20.
  • Each of these members 20, 21, 22 and 24 is connected with its respective third section 12 and 16 by appropriate connecting members such as a pair of screws 25.
  • An insulating block 20 is disposed between each of the jack springs 21 and 22 and the connecting springs 24 to electrically insulate such springs from each other.
  • each of the jack springs 21 and 22 and each of the connecting springs 24 have a portion extending past the end of the frame members and past the insulating blocks 20.
  • certain of these spring member portions are electrically connected with each other. Conventionally, such connections are accomplished by soldering connecting wires between selected spring members.
  • electrical connection is achieved between selected spring members 21, 22 and 24 by means of a circuit board which is illustrated best in FIGS. 8 and 9 and identified by the reference numeral 45. Such a circuit board, however, can only be used when relative movement between the third sections 12 and 16 is eliminated.
  • the circuit board 45 is a relatively rectangular member having a plurality of holes 46 positioned to correspond to the portions of the spring members 21, 22 and 24 extending past the insulating blocks 20, thereby enabling the circuit board 45 to be connected with the jack in the manner illustrated in FIG. 2.
  • certain of the holes 46 are provided with connector members 48 which are adapted for electrical engagement with certain corresponding spring members 21, 22 and 24.
  • these connector members 48, and the spring members with which each is associated are electrically connected with certain of the other connector members 48 and spring members by a connecting means 49.
  • the connecting means 49 may be either printed circuits or metal strapping, the circuit board 45 in the preferred embodiment contemplates the use of printed circuits as the connect ing means.
  • a spacing block member 26 is disposed between the third sections 12 and 16 of the frame members. As illustrated best in FIGS. 3, 4, and 6 of the block member 26 is offset with respect to the third sections 12 and 16 to enable adjacent electrical jacks to be interlocked with respect to each other.
  • the block 26 also serves to prevent relative movement between the third sections 12 and 16 during use of the electrical jack, thereby enabling a circuit board to be used for electrically connecting the spring members 21, 22 and 24. Without the block 26, relative movement would occur between the third sections 12 and 16 when inserting a plug into the jack sleeve 18. For example, as illustrated in FIG.
  • a conventional jack plug 27 having a contact portion 28, a portion 29 by which the plug may be gripped and a cord 30 leading to a terminal (not shown) remote from the jack is adapted for insertion into one of the jack sleeves 18 such that the contact portion 28 engages the jack springs 21 and 22.
  • the plug in order to make such engagement, the plug must be pushed into the sleeve 18 a sufficient distance to enable the contact portion 28'to make appropriate engagement with the spring 22. When this is done, both the jack springs 21 and 22 are biased outwardly as a result of engagement with the contact portion 28.
  • the connecting section 31 between the third sections 12 and 16 and the second sections 11 and 15 respectively exerts pressure on the connecting section 31 between the third sections 12 and 16 and the second sections 11 and 15 respectively, tending to rotate the third sections 12 and 16 inwardly about the connecting portion 31.
  • the spacing block 26 between the third sections 12 and 16 no relative movement between the third sections is permitted. Because of the elimination of the relative movement between the third sections 12 and 16, a printed circuit board may be used to make electrical connections between certain of the spring members 21, 22 and 24.
  • the block 26 of the present invention is constructed from an electrically non-conductive plastic material.
  • the second section 15 includes a pair of male sleeve portions 32 which are adapted for insertion into a corresponding pair of female openings 34 to make the connection between the second sections 11 and 15.
  • the sleeve portions 32 and the openings 34 are preformed in the frame members and are positioned to insure proper alignment between the frame members when connected.
  • the exterior dimension of the sleeves 32 corresponds substantially to the internal dimension of the opening 34 to permit the sleeves 32 to be inserted into the openings 34 in a relatively tight relationship.
  • One end of eachof the openings 34 includes a beveled portion 35 enabling the ends of sleeves 32 to be peened by suitable means to securely connect the second sections 1 1 and l5to each other.
  • each of the third sections includes a pair of sleeves 36 extending. toward the opposing third section and functioning to retain the spacing member 26 between the third sections l2 and 16 inits proper position.
  • the spacing member 26 includes openings 38 and 39 extending therethrough with internal dimensions approximating the exterior dimensions of the sleeve portions36 so that the sleeves 36 may extend into the opening 38 and 39 when the member 26 is properly positionedbetween the thirdsections l2 and 16.
  • the internal surface of each of the sleeves 36 contains threads adapted for threaded connection with the screw members 25 (FIGS.1 and 2) for connecting the spring members 21, 22 and 24 and the insulating blocks (FIGS. 1 and 2) to the third sections 12 and'16.
  • the holes 38 and 39 which extend through the spacing block 26 are positioned to insure proper positioning of the block 26 be-- tween the third sections 12 and 16.
  • the block 26 also includes a second pair of openings 40 and 41 which serve as relief openings to eliminate certain stressed on the block 26.
  • the spacing block 26 is disposed between 1 the third sections 12 and 16 of the frame members such that a portion of the spacing block 26 extends outwardly from a first imaginary plan bridging afirst edge of the third sections 12 and 16. Further, a portion 44 of the spacing block 26 is recessed from a second imagineryplane bridging a second edge of the thirdsections l2 and 16 to enable the outwardly extending portion 42 of the block 26 of an adjacent jack to be interlocked with the recessed portion 44.
  • a plurality of electrical jacks may be mounted in sideby-side relationship in the manner illustrated in FIG. 6
  • adjacent jacks are interlocked as a result of the portion 42 of the block 26 extending into and interlocking with or engaging the recessed portion 44 of the block 26 of an adjacent jack.
  • the entire jack assembly is provided with additional vertical stability, a quality which none of the jacks have individually.
