According to the present invention, what a kind of making was used for providing protection to one or more electronic component EC is applicable to direct current
The thermal control switching device shifter on road (DC).
For this reason, first will have a bearing P, the circuit board be such as made up of suitable material or wire support, circuit board or wire support erection welding have one or more electric components EC.
A switching device SE is installed on this bearing P.Wherein, described switching device SE as shown in the figure, wherein weld with assembled electric components EC by one end, the other end of switching device SE by by heat energy softening, conductive increasing attached dose of S, such as solder or adhesive and be connected with electric interfaces CT.
Although above-mentioned installation step is arranged in sequence, also can set according to validity respectively various other order or the order of simultaneously carrying out.
In addition, install a shell H, wherein, described shell H has at least one section to have fire extinguishing auxiliary device.
Shell H such as can be used as in the location eyelet B that molded part is inserted on bearing P.A kind of mount scheme of alternative as shown in Figs. 4-6.Wherein, shell H is shifted onto on described bearing from the side.
Shell H is provided with applicable, the projection be molded on this shell H surface, protruding for shell H is positioned at bearing P.
But do not get rid of the mounting means of the substituting of other or complementarity thus, especially weld.Especially these mounting meanss can with additive method step, such as combine with the welding of components and parts EC, so as to make described manufacture method design thus more free efficiency and cost is lower.
So a kind of assembling mode of shell H can be integrated in manufacturing process, very favourable to cost.Because shell H has one section to comprise fire extinguishing auxiliary device, usual produced cannot just can being interrupted by the electric arc extinguished immediately in DC circuit (DC) application in a handoff situation, just as below.
