Fixed head 9 is bent into two ends can insert the shape that is fixed in the 1st fixed head ditch portion 25 that is arranged on the bottom shell 2; Fix with end fixed part 91; Pars intermedia forms the 2nd fixed part 92; Under the state that inserts bottom shell 2 peristomes 23, form and to insert the shape that is fixed in the 2nd fixed head ditch portion 34 that penetrates the back side 33 that is arranged on second housing 3.The claw 93 that can fix with the bottom shell 2 and second housing 3 is set on the end fixed part 91 of fixed head 9 and the 2nd fixed part 92, and the fixing recess (not shown) that corresponding claw 93 is provided with on the bottom shell 2 and second housing 3 is fixing through fixing respectively after fixing with claw 93.Therefore fixed head 9 makes second housing 3 that inserts in the peristome 23 of bottom shell 2 be positioned at peristome 23, and it is fixing that bottom shell 2 is connected with second housing 3.

Bottom shell 2 be arranged under the state of peristome 23 after second housing 3 is connected by plate 4, bottom shell 2 is very stable with the fixing of claw 93, bottom shell 2 relatively, claw 93 is fixed as the state that does not move.

Be fixed as the matched in clearance state between second housing 3 and the fixed head 9.That is, second housing 3 is as shown in Figure 5, and is provided with fixing between the bottom shell 2 behind the very little gap Y of formation.Therefore second housing 3 on 24 the face direction on bottom shell 2, be the state of removable slit Y part on the face direction of printed circuit board B installed surface.

At this moment; The plate 4 and second housing 3; Like Fig. 6 and shown in Figure 9, second housing 3 is in the central authorities of peristome 23, and under top 31 states that are located along the same line with top 21 of bottom shell 2 of second housing 3; Be arranged on the claw 93 on the plate 4 and be arranged on maintenance slit Y between the fixing recess 35 on second housing 3, fix with the matched in clearance state.Therefore, in second housing 3, in fact in peristome 23 except that fixed head 9, and between the bottom shell 2 for there not being a state that hinders the position.

Therefore, bottom shell 2 is installed in printed circuit board B go up after, even cause little distortion by bending etc., second housing 3 is constant with the relation of bottom shell 2 in the scope of gap Y, guarantees the position on the printed circuit board B.
