side legs 52 and 54 of the respective spring member while capturing the shank portion 70 between the bar and back leg 74 of the spring the spring pressure provided by legs 52 and 54 ensures the required electrical continuity the left housing section 22 is then assembled to the right section while the clips are held in position by the tabs 68 and 76 and the spring members are held in place by the projections 58 in the widened portion of the slot 56 it will be noted that other than the fastener 46 it is only necessary to slide or insert the spring members 50 in their respective recesses by first compressing the legs for engaging the respective integrally formed projections and passages thereafter inserting the clip members 60 and 62 in member 50 to engage the integrally formed tabs and passages and secure the joint assembly whereafter the insertion of the bus bars between the clip members 60 and 62 firmly clamps the bars to the assembly the bus bars may of course be assembled to the respective housing section 12 before the clip assembly 16 this being a matter of choice the housing assemblies may then be shipped for use at a desired site thereafter when it is desired to utilize the housing assemblies to electrically connect the bus bars in tandem or series the extending end of a left housing section.
