Abstract

Disclosed is a single-hole multipole safety socket; multipole lines in the same group share a jack; electrodes of live line and zero line of the socket are hidden behind the periphery of an insulation isolation cylinder; the isolation cylinder is automatically supported tightly under the socket panel through a spring; thereby, a special plug is adopted to push the isolation cylinder into the socket hole, and then the isolation cylinder is rotated in certain angle, then the convex electrodes of plug can be connected with the electrodes of the live line and zero line of the socket.

Description

The multipole safety socket of single hole

Affiliated technical field

The utility model relates to a kind of safety socket of electrical equipment.

Background technology

Two holes at existing equal the two poles of the earth of common socket, three holes of three utmost points, there are several common problems in this socket: plug and socket only depend on the frictional force of electrode to interact, and come off easily; After using a period of time, electrode contact blade fluffs will loose contact; Easily by false touch, electrode exposed etc. and all to have potential safety hazard electrode exposition when plug and socket were tight in the use in jack when not busy; Original so-called safety socket remains two holes at the two poles of the earth, three holes of three utmost points, and assembly is comparatively complicated, but still fails to solve fully foregoing problems.

Summary of the invention

It is stable that the purpose of this utility model provides a kind of plug insertion depth, difficult drop-off, and plug holds out against automatically with the socket electrode and contacts during use, automatic hidden single hole multipolar system safety socket and the plug special thereof of electrode in socket when not busy;

Technical scheme

The utility model is achieved in that the socket of the two poles of the earth no matter or three utmost points, a jack is all only established on same group of the two poles of the earth of socket or three polar curve roads, the start to exchange fire electrode of line and zero line of socket when not busy in the jack is hidden behind peripheral at movable insulation isolating cylinder, isolating cylinder is held out against under socket panel automatically by spring, like this, can't see the electrode that connects live wire and zero line in the socket aperture, can only see the outlet ground utmost point at the bottom of the isolating cylinder, thereby guarantee the Electrical Safety purpose; It before the plug one section stem stem, the top is the earth electrode contact, both sides have the live wire and the zero wire electrode of evagination respectively, during use, on the one hand by the outlet ground contact at the bottom of the plug end roof pressure isolating cylinder, in addition, the outer convex electrode roof pressure isolating cylinder edge of plug compresses spring together isolating cylinder is retreated, and exposes the gap that the outer convex electrode of enough plugs passes through, at this moment, with plug rotate about 90 the degree after plug electrode is contacted with the electrode of socket, the realization circuit communication, simultaneously, the rear spring of loosing one's grip resilience compresses electrode corresponding between plug and socket automatically, makes their contacts good; In addition, the utility model is not only applicable to single phase circuit, single-phase-two-wire or when three-way live wire and zero wire electrode be that the relative opening heart 180 is symmetrically distributed, also go for three-phase circuit, during three-phase and four-line three-phase electrode press the 120 degree distributions of relative opening heart septum; On the product type, both can be designed to the fixed socket of cling matrix, movable socket, also can be the portable electric wire of typing, the joint of cable etc.

Beneficial effect

The beneficial effects of the utility model are:

1. the outer convex electrode of plug both sides is held out against, is snapped in the socket aperture side groove after rotating an angle, must rotate an angle again and just can extract, and therefore, plug can not get loose easily, the hidden danger that plug electrode exposes can not occur yet;

2. when not busy, the socket live wire in the socket aperture and the electrode of zero line are hidden can not to be caused the accident by false touch in insulation isolating cylinder both sides behind, and its fail safe is improved;

3. spring holds out against socket and plug counter electrode in groove, and each respective electrode of outer protrusion electrode of each of plug and socket aperture side closely contacts simultaneously, thereby contact performance is good;

4. only realize one group of live wire, zero wire electrode hidden automatically to socket having high performance-price ratio with an isolating cylinder and spring, and, can reduce and damage or fault.

Description of drawings

Below in conjunction with embodiment, accompanying drawing the utility model is further specified:

Fig. 1 is single hole multipolar system safety socket and plug special vertical section connection diagram thereof

Fig. 2 is the socket sectional arrangement drawing

Fig. 3 is the plug sectional arrangement drawing

Among the figure: 1. outer convex electrode 7. plug stem stems of socket electrode 2. isolating cylinders 3. springs 4. jack housing 5. plug handles 6. plugs

Embodiment

Be used for single-phase-two-wire shown in Fig. 2 or the three-way multipole safety socket of single hole is made up of socket electrode 1, isolating cylinder 2, spring 3, jack housing 4 etc.; The plug special of Fig. 3 is made up of plug handle 5, the outer convex electrode 6 of plug, stem stem 7 etc.During enforcement, jack housing, isolating cylinder, plug stem stem, plug handle etc. adopt injection mo(u)lding, and jack housing and plug handle are reserved electric wire respectively and inserted the hole; Electrode adopts the copper coin punch forming; Spring is a standard component; Outer convex electrode postpone injection moulding or after stem stem stays groove, insert to cover and cement in advance on the plug stem stem; Between the shell upper and lower part, adopt hasp, screw thread or screw to fix between plug handle and the stem stem.

Claims

1. the multipole safety socket of single hole is made up of socket electrode, isolating cylinder, spring, jack housing etc.; It is characterized in that jack of one group of multipole line sharing, a plurality of electrodes of live wire and zero line are hidden behind peripheral at a movable insulation isolating cylinder in the socket, and isolating cylinder is held out against under socket panel automatically by spring.
