Son 141 can still be exposed by opening 115, and the electrical lead of external devices can enter shell and directly electricity by opening 115
It is connected to electric terminal 141, do not have to that any intermediary device is arranged between the electrical lead and electric terminal 141 of external devices or is led
Line.In some embodiments, sealing element (not shown) or support plate can be set between opening 115 and support plate 140
Perfusion sealing glue in gap between 140 and opening 115, to prevent external substance (such as dust, water etc.) via support plate
Gap between 140 and opening 115 enters shell 110.In the certain embodiments of the application, can also will be open 115 structures
Cause only to allow electric terminal 141 itself to exceed the outer surface of shell 110, i.e. some or all of electric terminal 141 is from shell
Internal portion reaches other than shell, and to be electrically connected with external devices, but support plate 140 itself does not stretch out except shell.
Further, in the certain embodiments of the application, such as can be by making support plate 140 attach to coil
132, the side parallel with the axial direction of shell 110 in the assembled state, so that coil block is arranged so that support plate 140
(or electric terminal 141 on support plate 140) can be exposed by the side wall 113b of shell 110 or the appearance beyond shell 110
Face.Correspondingly, in some embodiments, the lateral surface 140a of support plate 140 can be configured to flat with the surface of side wall 113b
The neat or surface beyond side wall 113b.
