Embodiment
(the 1st embodiment)
Then, with reference to the accompanying drawings of an example of embodiments of the present invention.Fig. 9 is the stereographic map of the related lighter unit 100 of present embodiment, and Figure 10 is the partial perspective view that is mounted with the projecting display 200 of lighter unit 100.
With reference to Fig. 1, the end 16 of the negative electrode current-carrying plate 6 that lighter unit 1 is set has the face 17 vertical with housing front surface 2a and the face 18 parallel with housing front surface 2a, and through hole 6a is arranged on face 17.On the other hand, 16 of the ends of the negative electrode current-carrying plate 6 that the lighter unit 100 shown in Fig. 9 is set have the face 18 parallel with housing front surface 2a, on this face 18, are provided with through hole 6a.
At this, as shown in figure 10, if the inner side that lighter unit 100 is inserted to framework 21 from peristome 23, the opening surface of peristome 23 is parallel with housing front surface 2a.That is, housing front surface 2a forms the first surface parallel with the opening surface of peristome 23.
In addition, as mentioned above, the end 16 of negative electrode current-carrying plate 6 is parallel with housing front surface 2a.That is, the end 16 of negative electrode current-carrying plate 6 form and the opening surface of peristome 23 is parallel second.
And then as shown in Figure 9, the end 19 of anode conducting plate 5 is parallel with the end 16 of negative electrode current-carrying plate 6.That is, the end 19 of anode conducting plate 5 form and the opening surface of peristome 23 is parallel the 3rd.
If Fig. 1 and Fig. 9 are compared, the set flange 10c in the lighter unit 100 flange 10c more set than lighter unit 1 is short.Specifically, the set flange 10c in lighter unit 1 forms along the overall length on a limit of housing front surface 2a.On the other hand, the set flange 10c in lighter unit 100 forms along roughly 2/3 length on a limit of housing front surface 2a.Therefore, as shown in figure 10, if lighter unit 100 is inserted into the inner side of framework 21 from peristome 23, on the right side (top of flange 10c) of lighter unit 100, form the first peristome 110, in the left side (top of flange 10a) of lighter unit 100, form the second peristome 111.In other words, by lighter unit 1, peristome 23 is divided into the first peristome 110 and second peristome 111 these two parts.
Figure 11 is the sub-4a(Fig. 9 of cathode end with lighter unit 100) stereographic map of the cathode line 30 that is connected.Cathode line 30 shown in Figure 11 is cables identical with the cathode line 30 shown in Fig. 3.But the connection fittings 131 that the cathode line 30 shown in Figure 11 is installed are different from the connection fittings 31 that the cathode line 30 shown in Fig. 3 is installed.Connection fittings 131 have: flat pedestal 132, the end of fixed negative pole line 30; Connecting portion 133, vertically erects from pedestal 132; And pair of sidewalls portion 134, from pedestal 132, vertically erect.Pedestal 132 is roughly rectangle, and connecting portion 133 erects from the minor face of pedestal 132.On the other hand, side wall portion 134 erects from two long limits of pedestal 132 respectively.In addition, connecting portion 133 is provided with threaded hole 135, and threaded hole 135 center is consistent with cathode line 30 center.And then two side wall portions 134 of connection fittings 131 across the central shaft of cathode line 30 and relatively.
Figure 12 means the stereographic map of the state that arranges of lighter unit 100.As shown in figure 12, utilize protective shield 400 to cover the lighter unit 100 of framework 21 interior settings.Figure 13 is the upper surface stereographic map of protective shield 400, and Figure 14 is bottom isometric view.Protective shield 400 is provided with for keeping a pair of fixture 401 and a pair of fixed head 402 of cathode line 30.Each fixture 401 major limitation cathode line 30 movements on axis direction.A pair of fixed head 402 major limitation cathode line 30 movements diametrically.
As shown in figure 15, the connection fittings 131 of installing in cathode line 30 connect and are fixed on negative electrode current-carrying plate 6.Specifically, if lighter unit 100 is inserted in frameworks 21, the end 16 and connecting portion 133 butts of negative electrode current-carrying plate 6.Thus, the through hole 6a(Fig. 9 arranging in the end 16 of negative electrode current-carrying plate 6) and the threaded hole 135(Figure 13 arranging in connecting portion 133) be communicated with.Therefore,, by the 3rd bolt (bolt 132) inserting in through hole 6a is screwed together in threaded hole 135, can connect and be fixedly connected with accessory 131 and negative electrode current-carrying plate 6.At this, as mentioned above, utilize the end 16 of negative electrode current-carrying plate 6 to form and the opening surface of peristome 23 is parallel second.That is, the head of connection fittings 131 and the fixing bolt 132 of negative electrode current-carrying plate 6 is positioned on second.And the axle of bolt 132 is vertical with second (opening surface of peristome 23).And the axle of bolt 132 is consistent with the central shaft of cathode line 30.
With reference to Figure 16, described bolt 132 is positioned at the inboard of the first peristome 110.And, fixing bolt 61a, the 61b of power lead 60a, 60b is positioned to framework 21 outsides.And then the 4th bolt (bolt 62) that the end of anode conducting plate 5 19 and the 4th not shown link are fixed is positioned at the inboard of the second peristome 111.Therefore, can contact from the side 21a of framework 21 all bolts (132,61a, 61b, 62).
In addition, on known with reference to the accompanying drawings bolt 62 is positioned on the end 19 of anode conducting plate 5 the 3rd.In addition, the 4th link is by the sub-4b of anode conducting plate 5(anode output end) be connected with the anode-side of bulb.
As mentioned above, in the related projecting display 200 of present embodiment, do not unload upper surface panel 500(Figure 10) can contact all bolts (132,61a, 61b, 62).In other words, only unload the side panel (not shown) of covering frame body side surface 21a, can contact all bolts.In other words, only unload side panel, can load and unload lighter unit 100.
And then all bolts have identical shaped, same size.Therefore, can utilize identical instrument to tighten or unscrew all bolts.
In addition the movement that, cathode line 30 makes progress in axis direction and footpath is limited.Therefore,, tightening or loosering a bolt, do not need to press connection fittings 131 at 132 o'clock.
In addition, as shown in figure 17, cooling fan unit 50 is fixed on protective shield 400.But, according to the explanation by the end of this, can easily understand that not unloading cooling fan unit 50 can load and unload lighter unit 100.
And, can make the reversal of poles of lighter unit 1.That is, input terminal 3a can be made as to anode input terminal, input terminal 3b is made as to negative electrode input terminal.Equally, lead-out terminal 4a can be made as to anode output end, lead-out terminal 4b is made as to cathode end.
And the cable being connected with lighter unit 1 also can change to other links such as current-carrying plate.In the situation that cathode line 30 is changed to the link that current-carrying plate etc. has rigidity, also can omit fixture 401 and fixed head 402.
