摘要： An electrical connector includes a base, a contact housing plate and a cover. The contact housing plate is coupled to the base and includes an electrical receptacle which is adapted to engage an electrical plug. The cover is also coupled to the base and overlies the contact housing plate. The cover has an inclined surface which extends toward the base and an opening therein forming a recess for receiving the electrical plug that is engageable with the electrical receptacle. The cover also includes a lid, which is movable between an open position and a closed position. When the lid is in the open position, the contact housing plate is exposed, facilitating access to the electrical receptacle. When the lid is in the closed position, the lid protects the electrical plug from debris and dislodgement from the electrical receptacle. The electrical connector may further include a plurality of electrical receptacles and openings for receiving multiple electrical plugs. The electrical connector may also include a circuit board which may contain an on/off switch and a circuit breaker with surge suppression. In addition, the plug of the power cord for the electrical connector may contain a built-in GFCI circuit.

摘要翻译： 电连接器包括基座，接触壳体板和盖。 接触壳体板联接到基座并且包括适于接合电插头的电插座。 盖子还联接到基座并且覆盖在接触壳体板上。 盖具有朝向基部延伸的倾斜表面，其中形成有用于容纳可与电插座接合的电插头的凹部的开口。 盖子还包括盖子，盖子可在打开位置和关闭位置之间移动。 当盖子处于打开位置时，接触壳体板被暴露，便于进入电气插座。 当盖子处于关闭位置时，盖子保护电插头免受碎片的影响并从电插座上移开。 电连接器还可以包括用于接收多个电插头的多个电插座和开口。 电连接器还可以包括可以包含开/关开关的电路板和具有浪涌抑制的断路器。 另外，用于电连接器的电源线的插头可能包含一个内置的GFCI电路。

摘要： A dental wrench is described having a structure which permits application of differing torques to the bur securing collet of a dental handpiece and the end cap of the turbine housing in a single wrench assembly. The wrench combines a shaft, for engaging the bur securing collet, supported rotatively in a frame member and secured to a support member which has means for engaging the end cap of the turbine housing. Interlocking means are provided between the support member and the frame member so that the wrench can be rotated as a unitary assembly to secure or remove the end cap of a turbine housing. The interlocking means are releaseable so that the shaft can be rotated independently within the frame member to secure or remove a dental bur in or from the collet of the handpiece housing. That portion of the frame member which is gripped for securing the end cap of the housing is of larger diameter relative to the support member so that increased torque can be applied to the end cap when the interlocking means is engaged to securely fasten the cap to the housing.
