CN2742602Y - Socket with protective door - Google Patents

Abstract

The utility model discloses a socket with a protective door, comprising a panel, a protective door, a reset elastic component, and a separator plate. The protective door is positioned between the panel and the separator plate, comprising two gates matched through a guidance axis and holes; the guidance axis and the holes are positioned in the middle of the protective door in length direction; the reset elastic component is arranged between both outer sides of the protective door and the inner side wall of the socket in axial direction along the guidance axis, positioning in the middle of the protective door in length direction. As the guidance axis and the holes of the protective door are positioned in the middle, accordingly, the problem that as the protective door in the two pole obround socket has greater volume, the mounting is difficult is effectively solved; as the protective door adopts a greater base structure, the mounting position of the reset elastic component, the guidance axis, and the holes have enough design space; as the contact surface of the protective door base and the guidance slot is a flat surface, the sliding of the protective door is flowing and smooth; the hand feeling of the protective door during the using process is good because of the copper reset elastic component withsmall compression force.

Description

A kind of socket with shutter

Technical field

The utility model relates to a kind of socket, the oblate double-purpose socket in particularly a kind of the two poles of the earth with shutter.

Background technology

Having shutter on the socket, is in order to improve the fail safe that socket uses, and avoids the contingency that is ignorant of getting an electric shock owing to misoperation or child.The present commercially available oblate double-purpose socket in 220V the two poles of the earth, narrow and small because of its inner space, great majority are not with shutter or band shutter but are only played dustproof effect and can not prevent effectively that one pole from inserting, and exists very big potential safety hazard.China's utility model patent discloses the applicant's " a kind of oblate dual-purpose socket " for No. 00258801.3, comprise panel, dividing plate, be provided with by left and right shutter dimerous between panel and the dividing plate, be provided with the Flexible Reset parts between shutter and the socket inwall; Left and right two parts of shutter combine by the axis of guide and the pilot hole at its two ends; the middle part of shutter downside is provided with the bar shaped projection; be provided with convex tendon around the upper side plane of dividing plate, the middle part offers the bar shaped gathering sill that matches with above-mentioned bar shaped projection to form the seesaw structure.When the two oblate jack of double bolt on panel of its same system plug touches shutter and overcomes the thrust of Flexible Reset parts, shutter promptly leaves the position of sealing two oblate jacks along the slide rail on the dividing plate, and double bolt is entered pedestal and realizes being electrically connected normally with sleeve; Extract latch, shutter returns the position of sealing two oblate jacks at the thrust lower edge of Flexible Reset parts slide rail; If in the shutter one side application of force, then shutter is to lopsidedness and embed between the convex tendon of dividing plate, and the convex tendon spacing is slightly larger than the shutter width, and under the restriction of convex tendon, shutter can not be opened, thereby plays the electrocution-proof protection effect.This socket protective door is because its axis of guide, hole are located at the two ends of shutter, and the shutter volume is bigger, is unfavorable for installing and using in the oblate double-purpose socket in small-sized the two poles of the earth.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of shutter volume less and can effectively prevent the socket that one pole inserts.

For achieving the above object, the utility model comprises panel, shutter, Flexible Reset parts, dividing plate, shutter is between panel and dividing plate, and this shutter is formed by two and half that match by the axis of guide, hole, and the described axis of guide, hole are positioned at shutter centre position along its length; The Flexible Reset parts axially are located between shutter two outsides and the socket madial wall along the axis of guide, and are positioned at shutter centre position along its length.

The utility model compared with prior art because the position in the axis of guide, hole changes the centre on the shutter from both sides, thereby efficiently solves the problem that the shutter volume is bigger than normal in the oblate socket in present the two poles of the earth, installation is difficult.Shutter has adopted bigger base construction in addition, makes the installation site of Flexible Reset parts and the axis of guide, hole that enough design spaces be arranged, and the contact-making surface of shutter pedestal and gathering sill is the plane, makes the slip of shutter more smooth and steady.These Flexible Reset parts adopt the copper spring of little compression stress, make shutter in use not influence feel.

Accompanying drawing 1 is the parts perspective exploded view under the confined state of the present utility model; Accompanying drawing 2 is that the master of accompanying drawing 1 looks the complete section schematic diagram; Accompanying drawing 3 is the parts schematic perspective views under the shutter assembled state of the present utility model; Accompanying drawing 4 be under the utility model confined state the back-moving spring position overlook the complete section schematic diagram.

Specific embodiments

As shown in the figure, the socket of band shutter of the present utility model comprises assemblies such as panel 1, shutter 2, back-moving spring 3, dividing plate 4, sleeve 5, back seat 6, shutter and is installed in the gathering sill 8 in dividing plate centre position by the pedestal 7 of its lower end, center between panel and dividing plate slidably; Shutter is formed by two and half that match by the axis of guide 9, hole 10, has the axis of guide on one of them half, has corresponding with it pilot hole on another half; The described axis of guide, hole are positioned at shutter centre position along its length.Two and half of shutter when being in closed condition form to the inclined-plane of joint inclination at the position relative with panel jack respectively, and two and half lower ends on the inclined-plane are meshed with ladder face structure; Described back-moving spring axially is located between shutter two outsides and the panel madial wall symmetrically along the axis of guide, and is positioned at the top in the axis of guide, hole, and back-moving spring compresses applying with two parts of shutter; The dividing plate middle part of shutter below is provided with the gathering sill parallel with the axis of guide, shutter is played the effect of supporting, guiding.The top end face of dividing plate and the corresponding position of shutter two ends are respectively equipped with stopper slot, and the width of this stopper slot width of shutter when closed is bigger.When any side of shutter imposed unbalanced active force, shutter can be oblique to this inclination, and this side head enters in the stopper slot of dividing plate top end face, makes two and half of shutter can't separate, thereby reach the purpose that prevents that one pole from inserting.On the panel madial wall above the shutter two ends, be respectively equipped with positive stop lug boss in addition; the width of shutter when the spacing of boss is slightly larger than closure; when shutter one side is stressed, deflect like this; the opposite side perk also makes two and half of this perk one side can't separate under the effect of panel positive stop lug boss, and the security reliability of socket is further strengthened.

The panel jack below is provided with and the perpendicular latch guide plate in plane, jack place.This guide plate can guarantee that latch inserts socket with basic vertical with panel direction, avoids the problem of going into to cause shutter to open because of the one pole oblique cutting.Back-moving spring of the present utility model in addition adopts copper spring, and it is more smooth and easy under the topic latch to be inserted before the reliability that guarantees shutter, and feel is better.
