Embodiment
Referring to Fig. 1,2, this routine jack base housing 1 end face is provided with two-phase housing jack 11.
Over cap 2 both lateral sides are positioned at the position in catch 41 outsides; be respectively equipped with the lid sidewall 23 that erects; two lid sidewalls are respectively equipped with the lid retaining wall 26 that extends internally, also faces toward these side screening glass catch 41 inclined-plane low sides; lid retaining wall 26 can play position-limiting action to latch post; and catch 41 played unidirectional position-limiting action, it can only be rotated towards the circumferencial direction of the high extreme direction in inclined-plane.
The sidewall of screening glass 4 vertical sides is plane; elastomeric element 3 is a cylindrical spring; spring is attached on this side plane sidewall; its inner end withstands on the spring retaining wall 44 of the outside protrusion that this sidewall is provided with; and be enclosed within on the reference column of spring retaining wall; the outer end withstands on the over cap lid sidewall 23 relative with it along rectilinear direction; and be enclosed within on the reference column that is provided with on this lid sidewall; prevent that it from sliding, position, spring outer end is contained in the gathering sill of being made up of this side cover retaining wall 26 and outside wall in parallel 27.
