る。２９はハンダである。 As shown in FIGS. 3 and 4, the main part of the present invention is that on the outer wall surface of the terminal block 16 of the storage battery block 2,
A pair of the above-mentioned connection plug pins 4 are provided protrudingly, and
An insulating cylinder 17 made of a soft elastic material, which is slightly longer than the connecting plug pin 4, is protrudingly provided around each connecting plug pin 4, and an opening 18 is provided in the tip surface of the insulating cylinder 17. In Figure 3, the terminal block 16 that also serves as a battery cover has a cover mounting post 24 and a screw 2.
Fixed by 5. 26 is a mounting hole. The shape of the opening 18 is preferably a cross-shaped slit as shown in FIGS. 4a and 4b. Further, as a means for fixing the insulating cylinder 17, it is easy to hold the base flange 19 of the insulating cylinder 17 with the flange 20 of the plug pin 4 and make it protrude from the same hole 21 as shown in FIG. 4a. FIG. 4c shows a state in which the connecting plug pin 4 is fitted into the jack 5 on the side of the device main body 1, and the insulating cylinder 17 is pressed by the flange 15 of the jack 5 and bent into a bellows shape. In the figure, the plug pin 4 and the jack 5 are respectively connected to the peripheral wall 2 made of synthetic resin.
3 is fixed by hot melting. 29 is solder.

い。 In this embodiment, as shown in FIG. 3b, the connection plug pin 4 is provided in the recess 22 of the storage battery block 2 so that it does not break when it hits an object, and the jack 5 of the device main body 1 is made to protrude by that amount. Therefore, a jack 5 is used as a means for pressing the insulating cylinder 17.
Although the tip flange 15 of the jack 5 is used, depending on the case, the tip of the jack 5 may be provided on the same surface as the outer wall surface of the device main body 1. In that case, the insulating tube 17
can be pressed by the outer wall surface of the device main body 1, so the tip flange 15 of the jack 5 is not necessarily necessary.
