(b) a plurality of pairs of levers coupled to the block,
(a) inserting an end of the insulated conductor of the first data cable at least partially into an insert guide of a first lever of a pair of levers of said pairs of levers of the connector block;
(b) moving said first lever from an open condition of use towards a closed condition of use so as to effect said relative movement and electrically terminate the end section of the insulated conductor with a corresponding IDC;
(c) inserting an end of the insulated conductor of the second data cable at least partially into an insert guide of a second lever of said pair of levers of the connector block; and
(d) moving said second lever from an open condition of use towards a closed condition of use so as to effect said relative movement and electrically terminate the end section of the insulated conductor with a corresponding IDC,
FIG. 2 b is an assembled view of the section connector block shown in FIG. 2 a;
FIG. 2 c is another view of the section of the connector block shown in FIG. 2 b;
FIG. 2 d is another view of the section of the connector block shown in FIG. 2 b with the levers arranged in another condition of use;
FIG. 2 f is a front view of the section of the connector block shown in FIG. 2 b;
FIG. 2 g is a top view of the section of the connector block shown in FIG. 2 b;
FIG. 3 a is another view of the section of the connector block shown in FIG. 2 b coupled to insulated conductors;
FIG. 4 b is a back view of the lever shown in FIG. 4 a;
FIG. 5 a is a back perspective view of a second lever of a pair of levers of the connector block shown in FIG. 1; and
FIG. 5 b is a back view of the lever shown in FIG. 5 a.
The first lever 20 a of the pair 18 of levers includes a finger engaging section 29 and two spaced apart arms 31 a, 31 b extending therefrom to respective hinges 30 which act to move the lever 20 a between the open position shown in FIG. 2 d and the closed position shown in FIG. 2 b. Similarly, the second lever 20 b of each pair 18 of said levers includes a finger engaging section 29 and two spaced apart arms 31 a, 31 b extending therefrom, inside the spaced apart arms 31 a, 31 b of the first lever 20 a, to respective hinges 30 which act to move the lever 20 b between the open position shown in FIG. 2 e and closed position shown in FIG. 2 b. The arms 31 a, 31 b of the first lever 20 a and the arms 31 a, 31 b of the second lever 20 b cross over one another during movement between open and closed conditions of use. As particularly shown in FIG. 2 e, movement of the second lever 20 b away from the closed condition of use is limited by the arms 31 a, 31 b of the second lever 20 b bearing against the body of the finger engaging section 29 of the corresponding first lever 20 a.
The hinges 30 of each lever 20 a, 20 b include lugs 33 extending outwardly away from the arms 31 a, 31 b of the levers 20 a, 20 b into corresponding apertures 35 of the block 10. The arms 31 a, 31 b of each lever 20 a, 20 b are at least partially resiliently compressible with respect to each other so that the lugs 33 can be located in corresponding apertures 35. The levers 20 a, 20 b can thereby be coupled to, or removed from, the block 10. As particularly shown in FIG. 2 a, the lugs 33 include a camming surface 37 for mating with corresponding camming surfaces 39 of the apertures 35. The combined action of the camming surfaces 37, 39 of the lugs 33 and apertures 35 facilitate easy fitting of the levers 20 a, 20 b to the housing 22.
As particularly shown in FIG. 2 a, spring finger contacts 38 of opposed IDCs 14 in the first and second rows 12 a, 12 b resiliently bear against each other and hold the opposed IDCs 14 in electrical contact. As particularly shown in FIG. 2 f, the front part 22 a of the housing 22 includes a testing cavity 40 shaped to receive a testing tool to separate the spring finger contacts 38 of opposed IDCs 14. The testing cavity 40 is accessible when the levers 20 a, 20 b are in the closed position, as shown in FIG. 2 f.
As shown in FIGS. 2 a, 3 a and 3 b, each IDC 14 is formed from a contact element that is bifurcated so as to define two opposed contact portions 26 separated by a slot into which the insulated conductors 44 are pressed so that the edges of the contact portions 26 engage and displace the insulation 46, and resiliently engage, and make electrical connection with, the conductor 48 in the insulated conductor 44. The contact portions 26 project through the slots 28 in the front part 22 a of the housing 22 for engagement with the insulated conductors 44.
When the insulated conductors 44 are seated correctly in each lever 20 a, 20 b, the terminal ends of the insulated conductors 44 are visible abutting the end wall of each slot 64 a, 64 b, 84 a, 84 b through a window formed by a hole 114 in the respective lever 20 a, 20 b, as shown in FIGS. 3 aA and 3 b.
As particularly shown in FIGS. 4 a to 5 b, each lever 20 a, 20 b includes a pair of stopping projections 94 extending from respective arms 31 a, 31 b thereof. The stopping projections 94 limit the extent of rotation of the levers 20 a, 20 b when they engage the top end of the top part 22 a of the housing 22. Each lever 20 a, 20 b has a range of motion defined by its hinge axis 32, 34 by its length, and by stopping surfaces 94.
(i) Opening the levers 20 a, 20 b by manually and/or digitally rotating and lifting them substantially free of their IDCs 14;
(ii) Inserting the insulated conductors 44 into the corresponding levers 20 a, 20 b;
(iii) Confirming that the insulated conductors 44 are correctly inserted and seated by viewing the ends of the insulated conductors 44 through the holes 114;
(iv) Closing the levers 20 a, 20 b by manually (or digitally) pushing them toward the front part 22 a of the housing 22, and thereby pressing the seated insulated conductors 44 into the contact portions 26 of the IDCs 14;
(v) Closing the latches 100 by pushing the levers 20 a, 20 b into the closed position, which first deflects the projections 112 away from the side 104 of the front part 22 a of the housing 22, then snaps the projections 112 into the cavities 106 with an audible ‘click’ for confirming that the levers 20 a, 20 b are fully closed; and
(vi) Testing the electrical connection of opposed IDC pairs 66, 86 by inserting a testing tool into the spring contacts 38 of the front part 22 a of the housing 22 via the testing cavity 40.
