  • the projected back end portion lie of a socket unit is snugly fitted into the recessed front end portion llf of an adjacent socket unit 1 so that there is provided a secure joint between the adjacent socket units 1.
  • the joint between the socket units l is further enhanced by protrusions lllg formed in the front end surface of each base 11 as shown in FIGS. 4, and 5, which protrusions securely engage recesses (not shown) formed in the back end surface ofeach base 111.
  • Each socket unit ll further includes an integral mounting member 14 outwardly projected from the lower center portion of the back end surface of the base Ill, and a recess 15 formed in the corresponding location of the front end surface of the base 11 (FIGS. l and 2).
  • the recess l5 thus provided in the front end surface of a socket unit has a contour complementary to the configuration of the projected mounting member Ml formed in the back end surface of an adjacent socket unit I, so that the recess 15 and the corresponding mounting member M cooperate with each other to assist the close fitting between adjacent socket units 1 when the socket units are assembled together.
  • an end plate 6 formed of molded insulating material.
  • This end plate 6 is attached to the front end surface of the foremost socket unit after the assemblage of the socket units 1 has been completed.
  • the end plate 6 comprises a center base 61 and two separators 62 provided at the opposite sides thereof.
  • the end. plate 6 further comprises a mounting member 61a provided in the back end surface thereof, and a mounting member 6llb provided in the front end surface thereof.
  • the mounting member 61b in the back end surface of the end plate 6 is located and configured similarly to the aforementioned mounting member 14 provided in each socket unit I, and is intended to be received into the recess 15 formed in the adjacent socket unit I.
  • the mounting member 610 provided in the front end surface of the end plate 6 is located in alignment with the opposite mounting member 61b, while it is of greater dimensions suitable to receive thereinto the mounting member 14 of a socket unit if the socket assembly is further assembled to another socket assembly.
  • the front and back end surfaces of the end plate base 61 provide stepped portions 610 which are outwardly projected with respect to the front and back end surfaces of the opposite separators 62 so that the stepped portions 61c can cooperate with the recess 1 l f provided by the front end of the socket unit base 11.
  • the foremost socket unit 1 and end plate 6 have holes 11h and 61d, respectively, for receiving therein securing means such as rivets 7 when the end plate 6 is attached to the socket unit 1.
  • the terminal beds 12a and 12b are formed with recesses which are open at the upper and front surfaces thereof so as to define spaces for receiving metallic connecting means, as described hereunder.
  • each socket unit 1 is assembled together with the metallic connecting means 3 and 4 fitted in the recesses 11a, 11c and recesses 11b, 11d respectively, and the end plate 6 is securely attached to the socket assembly at the front end thereof by inserting therivets 7 into the holes 11h and 61d.
  • the base 11 of each socket unit 1 has an elongated recess lli formed in the upper surface thereof so as to receive therein a downward projection 211 provided in the lower surface of the relay 2 having plug-in terminals 2a.
