Effect.
Wherein, outside screw bolt passes upper end subshell, upper transmission structural housing, lower end subshell and underdrive structure
Shell is fastened four.
Adopt the structure so that four coordinate even closer.
Wherein, there is location structure between upper transmission structural housing and lower end subshell.
Wherein, the location structure includes locating slot and locating dowel；Locating slot and locating dowel, one is located at upper transmission knot
The lower surface of structure shell, another is located at the upper surface of lower end subshell.
Wherein, locating slot and locating dowel and bolt are to be arranged concentrically.
The design of location structure, it is convenient when lower end subshell is driven structural housing with assembling.
Wherein, also including upper connecting terminal and lower connecting terminal, upper connecting terminal is installed on upper terminal inside the shell and portion
Divide through upper end subshell and extend out to outside；Lower connecting terminal is installed on lower terminal inside the shell and partially passes through lower end subshell to be stretched
Go out to outside.
Wherein, upper connecting terminal upper surface of outer cover correspondence upper connecting terminal installation place is a sealing surface, on the subshell of lower end
Surface correspondence lower connecting terminal installation place is a sealing surface.
In prior art, upper connecting terminal upper surface of outer cover and lower connecting terminal shell corresponding terminal installation place open up
There is hole, as terminal is powered so needing the glue spraying in hole to reach the effect of electrical isolation in use.And adopt
It is a sealing surface that this kind of structure of this utility model causes upper and lower binding post upper surface of outer cover corresponding wiring terminal installation place, is reached
Effect to electrical isolation must not extra glue spraying.
Wherein, the shape of upper its cross section of transmission structural housing is identical with the shape of upper terminal cross-sectional outer.
After this kind of structure causes assembling, overall structure is more succinct.
Wherein, the shape of its cross section of underdrive structural housing is less than lower terminal cross-sectional outer size.
Wherein, nut bore is offered in underdrive structural housing, during bolt stretches into nut bore and without departing from nut bore, spiral shell
It is female to be located in nut bore.
Adopt the structure so that during bolt stretches into nut bore and without departing from nut bore, prevent bolt from scraping beyond nut
Hinder remaining object.
