Abstract

The utility model provides a socket with a switching function. The socket of the utility model is mainly applied in the field of low-voltage electrical apparatuses. When the socket is used, a socket cover is rotated and the purpose that a power is switched on or is switched off can be obtained. Because an annular retaining wall is arranged in the switch of the socket, when the socket is switched off, a conducting body with any shape is inserted in the jack of the socket, and the accident of electric shock can not occur.

Description

Supply socket with switching function

The present invention relates to a kind of improved supply socket, it can make socket have switching function, and this socket mainly is applicable to the low-voltage electrical apparatus field.

Existing surface mounted socket is not because the restriction of volume and cost all has switching device, and this socket has used following 2 deficiencies.

1. the danger of Chu Dianing is bigger, and hand is held conductor and do not noted slightly inserting in the jack, just electric shock accidents may take place, and this situation is the most common in the family.

2. a lot of electric equipments use the back because socket does not possess switching function.In order to prevent accident, often plug is pulled up in the time of power supply need being disconnected, pull up like this to use and bring some troubles.

The deficiency that the present invention remedies above-mentioned socket designs.Need only the turn socket cover during use and just can finish the purpose that connects or disconnects power supply.

Electric shock accidents designed a ring-type barricade in the socket cover, no matter the conductor that stretches into what type shape from socket when socket is in off state generally can not take place like this.Because socket is at the external make and break process of finishing of ring-type barricade, so do not influence the work of socket switch when plug is inserted on the socket.

The purpose of this invention is to provide a kind of supply socket that switching function is arranged, characteristics such as it has safe in utilization simultaneously, and is easy and simple to handle, and socket switch on-load ability is big, and cost is low.Owing to taked the very suitable use in the family of certain safety measure.

The present invention mainly partly is made of pedestal, switch cover, movable contact spring part and static contact.Static contact has partly comprised power supply introduction wiring hole, fixing hole and fixed contact, and they are contained on the pedestal of socket by fixing hole.Moving contact has partly comprised socket contact and switch movable contact and corresponding fixing hole, they are after passing fixing hole with fixed screw two groups of contacts to be separately fixed on the switch cover, rotation by switch cover drives its movable contact spring and partly moves, thereby finishes its switching process.

The invention is further described below in conjunction with accompanying drawing.

Fig. 1 adds the vertical view of static contact for the pedestal of socket.

Fig. 2 is the A-A profile of socket base.

Fig. 3 is static contact figure.

Fig. 4 is the fixed screw figure of socket cover.

Fig. 5 is the vertical view of socket cover.

Fig. 6 is the B-B profile of socket cover.

Fig. 7 is the stereogram of movable contact spring part.

Fig. 8 is the sectional drawing at moving contact place.

With reference to Fig. 1 (1) is a socket base of being made by bakelite, (17) (13) are static contacts, it includes fixing hole (18) (14) and power supply wiring screw hole (11) (12), also has fixed contact (15) (16), on pedestal, also has installing hole (3) (4), (7) (8) are two recessed sulculuses in addition, its effect prevents the movable contact spring slip and designs, (5) (6) breach is a restriction socket cover slewing area, (30) (29) two ledge alignment notch (6) (5) among Fig. 5 during installation, socket cover (33) can be operated within the effective range like this, (9) (10) are the through wires holes that two power supplys are introduced line, (20) are one and mould the round nut of casting in the projection (19) of pedestal (1) among Fig. 2, its effect is a floatless switch lid (33), screw (50) shown in Figure 4 is screwed in the aperture (2) during installation, when tightening, (21) on the screw are pressed together with nut (20), under before screw (50) is tight, inscribing like this, guaranteed that switch cover (33) can rotate flexibly, is unlikely to again to fall down.Fig. 3 is the enlarged drawing of static contact (17) and (13), and the static contact partial design becomes zig-zag type, and purpose is to allow the contact can be unsettled, can make things convenient for the work of fixed contact (15) and (16) like this.(32) are ring-type barricades among Fig. 5, this barricade (32) can be divided into inside and outside two parts to socket, when socket switch is in conducting, inside and outside two parts all have, when socket is in shutoff, have only the outer ring that electricity is arranged and inner ring does not have electricity, conductor inserts and can not get an electric shock when having guaranteed shutoff like this.(27) (28) are skidded when preventing the turn socket cover and are designed.For fixing movable contact spring part, on ring-type barricade (32), mould and be cast into two garden type nuts (25) (26).(22) be the installing hole of socket cover (33).(31) be for the aperture that neon lamp designs is installed, the breach of top (34) is a lead wire outlet, wiring along (34) pick out the back along the outer ring of socket cover (33) to inserted sheet, neon lamp is bright when inserted sheet has electricity like this, otherwise then do not work, (36) be a mounting groove on ring-type barricade (32), arrive in the sulculus (36) during installation and under the appropriate section of the installing hole (43) (37) of Fig. 7 movable contact spring part and (46) (39), can guarantee that like this movable contact spring part is loosening under the situation of often action.(23) (24) are jacks, (41) (45) are to go up two following convex portions that extrude at moving contact (49) (50), purpose is that the location is used, when socket cover (33) when going to off state, following convex portion (41) (45) can enter in (7) and (8) of pedestal (1), on off state can not change during the friction of (41) (45) and (7) (8) of having made every effort to overcome clothes not so outside, thereby has prevented misoperation.(38) (42) can make fixed contact (15) (16) insert accurately in moving contact (47) (49) and (48) (50) with the limit that these several wings of (40) (44) rise.

This socket when operation turn socket cover (33) at this moment moving contact (47) (49) and (48) (45) rotates thereupon, and socket is in conducting state when insertion fixed contact (15) (16).Moving contact (49) (47) and (48) (50) separated with fixed contact (15) (16) when Rotating socket covered (33) in the opposite direction, and socket is in off state.
