PROBLEM TO BE SOLVED: To facilitate both to solderably connect a base board and to lay around a cable in a thin box by providing a metallic series unit main body having a synthetic resin terminal block on a front face, and dividing a housing case having integrally branch and input/output terminals on front/rear faces in the depth direction into a main body case and a case cover so that a circuit board is shallowly exposed. SOLUTION: A T-shaped housing case of a series unit body 1 is divided into a main body case 7 and a case cover 8 in the depth direction, and is fixed by a machine screw 9. The main body case 7 having the case body part 7b continuously connected to the case head part 7a integrally forming a pair of input/output terminals 4 at the back, has the terminal block engaging parts 11 and the installing lug parts 6 on both side surfaces engaging with a terminal block 2 freely attachable to lower side two branch terminals. A circuit board 12 is exposed in a shallow position of the opening part of the main body case 7 by the division to thereby easily solderably connect a lead plate 20 pulled out by being bent downward from a terminal pin 5a and a terminal pin of of an input/output terminal 4 at the back of a branch terminal. |
