Abstract

A shock-preventing safety socket provided with switch and locking function includes a panel, a core pedestal, and a jack base, wherein a conductive tab is connected with a conductive contact shaft at its bottom, and the conductive contact shaft sequentially penetrates through the jack base and the core pedestal and protrudes out of the bottom surface from its lower part. An arc groove having the same center and diameter with the contact shaft is provided on a plane of the core pedestal, where the conductive contact shaft penetrates, and a group of elastic conductive contacts are symmetrically mounted on both sides of the start or tail end of the arc groove. A locking unit is mounted on the jack base in such a manner that a female thread round through-hole connected with the bottom surface of the core pedestal is provided vertically at the center position of the jack base, a lock core arranged in the hole has a specific shape matching with the key at its upper portion, and an insulator connected to the lower portion of the lock core sheathes the elastic conductive contacts of the main circuit at its lower part. The connection and disconnection between the circuit and the conductive tab can be controlled by rotating the jack base, and the locking unit can be used for controlling ON/OFF of the main circuit. Accordingly, the socket is safe, reliable, and convenient.

Embodiment

Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.

As Fig. 1～shown in Figure 5, electric shock-prevention safety socket with switch and lock control function comprises that the center has core print seat hole 1, the panel 3 of indicator light display window 2, core retainer plate base 4, jack core print seat 5, panel 3 adopts screw to be fastenedly connected with the shirt rim that is connected on the core retainer plate base 4, have in the core retainer plate base 4 jack core print seat 5 is installed take up hole 6, jack core print seat 5 is installed in the core retainer plate base 4 and by the core print seat hole 1 on the panel and appears panel 3, it axially has some jacks 7 of blind hole that are according to the electrical equipment standard arrangement in jack core print seat 5 upper edges, the quantity of jack can be two holes that are adapted to two core plug, also can be three holes that are adapted to three-prong plug, what present embodiment was cited be two holes.Opening conduction inserted sheet 8 up is installed in the jack 7, the 8 bottoms riveted joint of conduction inserted sheet has conduction to touch axle 9, conduction is touched axle 9 bottoms and is passed jack core print seat 5, core retainer plate base 4 and outstanding bottom surface successively, on conducting electricity the plane of touching the axle place of passing, the core retainer plate base has and touches the concentric arc groove 10 of axle with the footpath, be symmetrically installed with on the both sides, arc groove 10 top and be separated with insulation locating piece 12 between 11, two elastic conduction contacts of one group of elastic conduction contact.On the jack core print seat 5 lock control devices is installed, promptly vertically have the internal thread round tube hole 13 that is communicated with core retainer plate base 4 bottom surfaces in jack core print seat 5 centers, screw thread lock core 14 is housed in the hole, the special shape of lock core 14 upper ends for matching with key, as " △ ", " recessed ", " protruding " etc., lock core 14 lower ends are by the fixedly connected insulator 15 of steady pin, and insulator 15 bottoms are enclosed within main circuit electroconductive elastic sheet sky between insulator bottom surface and the baffle plate by bolt by baffle plate 16.In the electrical connection circuit, the elastic conduction contact of power firestreak end L serial connection main circuit conductive contact blade K, fuse F1, socket live wire end, the elastic conduction contact of zero-power line end N serial connection fuse F2, socket zero line side is between the two elastic conduction contacts and connect the series arm of indicator light P, current-limiting resistance R.Each electric component is installed in the core retainer plate base 4, and exposes supply terminals.Lock control devices also can adopt eccentric bit architecture, as shown in Figure 6, vertically have internal thread round tube hole 17 in core retainer plate base 4 at jack core print seat 5 eccentric positions, screw thread lock core 18 is installed in the hole, lock core 18 upper ends are nose cone for special shape, the lower end that matches with key, and there is the conical bore that matches with nose cone corresponding cone headed core retainer plate base 4 endoporus bottom surfaces.When the screw thread lock core is threaded to nose cone for 18 times and enters in the conical bore, jack core print seat 5 just can't rotate, socket is in the outage safe condition, otherwise, when nose cone is recessed conical bore, then rotatable jack core print seat 5 and drive conduction and touch axle 9 and contact with conductive contact blade 11, socket is in electricity condition is arranged, and this eccentric lock control devices particularly suitable is applied in the external product.
