Description
Technical field
The utility model relates to a kind of five hole plate connectors, particularly relates to a kind of five hole plate connector shutter structures.
Background technology
Current socket; in order to avoid potential safety hazard; the general shutter be all provided with for covering and stop socket electrode; when plug does not insert; can't see, also do not reach the electrode of the inside, play to avoid child or make metal small articles stretch into jack contact because of carelessness and cause personal injury to socket electrode, when plug inserts; can shutter be pushed open, thus make plug and socket electrode contact and obtain electric.But, in five current hole plate connectors, because two is slotting tight with three location arrangements of inserting; generally a shutter is all only set; that is cover three with a shutter to insert and two intercalative electrodes, when shutter is passed, three insert with exposed while of two intercalative electrodes simultaneously.Therefore; this shutter structure; when in five hole plate connectors use two to insert or three insert; that socket electrode do not used has not had shutter to cover; be in naked state; easy generation is played because of child or is made metal small articles stretch into jack contact because of carelessness and causes personal injury to socket electrode, still there is potential safety hazard.
Summary of the invention
The utility model mainly solves in original five hole plate connectors and only covers three slotting and two intercalative electrodes with a shutter simultaneously, if only use two insert or three insert time, that socket electrode do not used has not had shutter to cover, is in naked state, still there is the technical problem of potential safety hazard; A kind of five hole plate connector shutter structures are provided; its existing two slotting shutter has again three to insert shutters; two shutters are independent separately; when guaranteeing that five hole plate connectors only use two to insert or three insert; the socket electrode do not used still has shutter to cover and stops; the personal injury effectively avoided child to play or make metal small articles stretch into jack contact because of carelessness to cause to socket electrode, stops potential safety hazard, improves safety in utilization.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises the socket dividing plate be located between socket base and socket cover, socket dividing plate is provided with five hole combination hubs, socket dividing plate is also provided with left front coaming plate and right front coaming plate, socket membrane backside is provided with a rear block, two middle link stoppers are provided with in the middle of socket dividing plate, middle link stopper is inserted jack and three two and is inserted between jack, and rear block is positioned at the rear that three insert jack; Described two insert the tops of jacks is provided with two and inserts shutters, and two insert the front side of shutters and described left front coaming plate and right front coaming plate offsets, and two insert between the rear side of shutters and described middle link stopper and are connected with spring; Described three tops of inserting jack are provided with three and insert shutter, and front side and the described middle link stopper of three slotting shutters offset, and are connected with spring between the rear side of three slotting shutters and described rear block.At left front coaming plate, arrange two slotting shutters between right front coaming plate and middle link stopper, when two slotting shutters are closed, by the effect of spring force, front side and left front coaming plate, the right front coaming plate of two slotting shutters offset.When two insert plugs insert two insert jack time, insert under the effects of plug downforce two, overcome the elastic force of spring, promote two and insert shutters and move to middle link stopper, thus open two and insert shutters, two insert plugs and the two intercalative electrode grafting that are arranged on socket base and electric.Between middle link stopper and rear block, arrange three insert shutter, when three slotting shutters are closed, by the effect of spring force, front side and the middle link stopper of three slotting shutters offset.When three insert plugs insert three insert jack time, insert under the effects of plug downforce three, overcome the elastic force of spring, promote three and insert shutters and move to rear block, thus open three and insert shutters, three insert plugs and the three intercalative electrode grafting that are arranged on socket base and electric.The utility model existing two inserts shutter has again three to insert shutter; two shutters are independent separately; when guaranteeing that five hole plate connectors only use two to insert or three insert; the socket electrode do not used still has shutter to cover and stops; the personal injury effectively avoided child to play or make metal small articles stretch into jack contact because of carelessness to cause to socket electrode; stop potential safety hazard, improve safety in utilization.
As preferably; described two slotting shutters are T font; comprise vertical block and be connected in the left side of vertical block and two horizontal blocks on right side symmetrically; two horizontal blocks cover the top of two described slotting jacks; a spring is respectively connected with between the rear side of two horizontal blocks and two middle link stoppers; vertical block is passed from the interval between described left front coaming plate and right front coaming plate; described vertical block is provided with a groove; the bottom land of groove is provided with a through hole, and described through hole and described two three ground wire jacks inserting jack inserted in the middle of jack that are positioned at match.When two horizontal blocks cover on two slotting jacks, still can see or touch by the through hole of groove bottom land the ground wire jack that three insert jacks.Therefore, when three slotting shutters are opened, when three intercalative electrodes are exposed, still can guarantee that two slotting shutters are in closed condition.
