DETAILED DESCRIPTION OF THESE EXEM
PLARY EMBODIMENTS
Referring to Figure 1, it is seen that the essential feature of this invention device lies in a common chassis 1, having four quadrate pillars 11, 12 provided in the central area, executed in every two pillars facing and adjacent to each other, by a right angle, each pillar suitably spaced from one another. In both the frontal and the rear sections of the chassis are provided identical square hollows 13, spaced apart from a point bordering upon the nearest pillar 11 or 12 by a clearance corresponding to the thickness of a conducting element, the width of the hollow 13 is equal to the width holding it apart from the external point of the nearest pillars 11 or 12.Two shields 14 are formed contrasting each other and parallel to the axial direction of the chassis, so that a gorge 17 is produced by one such shield adjacent to the nearest pillars. In a traversing direction between the two shields 14 is provided a narrow hole 15, of which both ends approach the rim of the hollow. Two small holes 16 being provided in the same hollow in a position close to pillars 11 or 12.
In the said hollow 13 is provided an parallel wiring terminal 2, shaped "S", of which the bend 23 in the upper half and the tip of the upper skew portion 22 of the lower half constitute a vertical plane. The lower half of the said terminal can be engaged, by loosening, into the hollow, the upper half thereof projecting out of the hollow, the joint 21 can be engaged, after loosening, between a pair of contrasting shields 14, such that the upper skew portion 22 of the lower terminal may abut against the said hole 16.
Accordingly, a certain distance is produced between the bend 23 of the said terminal and the nearest pillars 11 or 12, approx. equal to the thickness of conducting element 3 or 4, reference is hereby called to Figure 2. The conducting element 3 roughly resembles the reverse shaped "Z", of which the top plate is a flat 31, the middle section is a vertical member 32, and the bottom another flat wing 33. Both flat wing 31 and vertical member 32 shared the same width as that of the said hollow, the same height as does the said pillars, whereas the width of another flat wing 33 is corresponding to the space between two adjacent pillars 11, so that its tip therefore stayed at the center of the facing pillars 11 and 12, and is further folded upwards to form a bracket 34.The other conducting element 4 resembles the shaped "Z", having like parts flat wing 41, vertical member 42 and flat wing 43 as does the said conducting element 3, but flat wing 43 hereby given two different reference, one of which the length is equal to the width of one of the said pillars 11 or 12, the other of no folded upwards of its tip.
The bracket 34 in said conducting element 3 may be loosened to give hold of a metal piece 5, said metal piece 5 having a notch 51 on either side of the middle section thereof, just to permit engagement in bracket 34. The length of the metal piece 5 is slightly shorter than the clearance prevailing between the contrasting vertical members 32, 42 once the two conducting elements 3, 4 are fitted unto the chassis.
As to the housing 6, it has a main body 61 having a complete quadrate space, to accommodate the pillars 11, 12, conducting elements 3, 4, metal piece 5, and bend 23 of wiring terminal 2 in association with the chassis. The wing 62 of the housing 6 thereof also contains a smaller space just permit enclosing of the rear upper portion of wiring terminal 2, like what is shown in Figure 2.
Further, the three conterminous walls of the housing 61 make up altogether an angle vertical 63 within, whereby the tip of flat wings 31, 41 of the conducting elements 3,4 may be pressed that the parts within are restricted from slackening, etc.
The seesaw units including spring 52, shaft 53, seesaw 54 are all of conventional structure and need not be given any further description.
By following the principle of the first embodiment hereof and reference to Figure 5 & BR<
Figure 6, metal piece 5 is discarded, conducting element 3 changed to 4, place the two conducting elements 4 are disposed in contraposition, the housing changed to such one as that bell-button type 7 generally used in a bell, the seesaw units changed to another bell-button units comprising bell-button 55, conducting flat spring 56 and spring 57, there you have at hand a bell-button contact recommended for use in a bell.
By following the said first embodiment hereof and reference to Figure 3 & Figure 4, it is seen that the terminal within hollow 13 of oneend of the chassis 1 is changed to be two independent terminal 8 from the state it once was, an parallel wiring terminal 2, so that they would not correlate each other but be disposed on both sides of shield 14 in said hollow 13 in the same direction instead, and the said conducting element 4 is changed to conducting elements 9, 10 for each coordinating terminal 8. The height of the conducting element 9 the same as pillars 12, having three conterminous sides just permitting enclosure of three sides of one pillar 12, so that the side of the pillar 12 which faces pillar 11 is let exposed.The top of one side central to the conducting element 9 is processed to yield a flat wing 91 and which the interior of such a flat wing bent downwards to yield a bumper 92, so that such a bumper is situated just by one side of the shield 14; whereas the side thereof confronting another adjacent pillar 12 is processed to have its base stretched out to yield a flat wing 93, of a length slightly shorter than the clearance holding two adjacent pillars 12 apart such that it may leave the adjacent conducting element 10 intact.
The height of another conducting element 10 is the same as that of the said pillar 12, and the element 10 is complete with three sides as defined hereinbefore, the side in middle having its top stretched out yield a flat wing 101 and which the interior of such a flat wing 101 bent downwards to be a bumper 102 just finding itself on the other side of the shield 14; whereas the side confronting another adjacent pillar 12 is provided with a flat wing in the middle, of which the length is the same as that of aforesaid flat wing 93. The functions of said bumpers 92, 102, it is to separate power lines, not shown, inserted respectively via hole 16, so as to keep them from associating with each other.The present embodiment is singular in that in addition to those disclosed heretofore, is the incorporation of another set of conducting element 3 on pillars 11, metal piece 5 seesaw units and housing 6 that is also used in the first embodiment, to account for a single-pole, double throw switch, and that one end of the metal piece 5 just accommodates itself between flat wing 93 and flat wing 103.
By following the said first embodiment hereof and reference to Figure 7 & Figure 8, it is seen that the two sets of pillars 11,12 on the chassis are each enclosed by a plug-seat 18 alike in substance. The height of the plugseat 18 is slightly higher than that of the said pillars 11 or 12, the width thereof the same as the hollows 13 in dimension, but the thickness thereof by just permitting clamping of pillars 11 or 12 and coverup of the top and both the frontal and back sides of the pillars.
The middle section of plug-seat 18 is provided with a clasp 181 by a width corresponding to the clearance separating it from the nearest pillar, in addition, aforesaid parallel terminal 2 may be provided in a loosened manner in the hollow 13, and a receptacle hereunder according to the present embodiment is produced by covering up the chassis with a housing 19, the underside of the insertion gap 191 made to bear against the plugseat.
When a power line, not shown in the configurations, is brought into the present invention via small hole 16, to be clamped by the bend 23 of terminal 2 or 8 and the upper skew portion 22 along the said vertical members 32, 42 or the said central side of conducting element 9, 10 or one side of the plug-seat 18, the upper flat wings 31, 41, 91, 101 of the conducting element or the interior of the housing 19 can be separated so that the power line may be restricted from being exposed outside the invention device. While the power line may be withdrawn by having a type screwdriver, not shown in the drawings, inserted via narrow hole 15 from a point outside the invention device, within to bear against the bottom side of terminal 2 or 8, thereby releasing the upper skew portion 22 of terminal 2 or 8.
