Description

Insert plug-in socket

(1) technical field

The utility model belongs to the electrical connection technical field, relates in particular to a kind of socket.

(2) background technology

Socket is a requisite electrical connection during the modern produces, lives.Existing socket is that the sleeve in the socket directly is connected with power-supply circuit mostly, and the plug slice by electrical equipment directly inserts in the sleeve of socket and reaches the purpose that is communicated with power supply in use.This socket is because sleeve is charged all the time, just make plug in the process of extracting and inserting, the inserted sheet on the plug also can be charged, and inserted sheet is outside being exposed to when plug does not insert socket fully or do not extract socket fully, directly or indirectly run into by staff easily, cause electric shock accidents.Therefore, there is potential safety hazard in this socket.

In order to address this problem, a kind of socket of charged source switch has appearred, and this socket is the security requirement that realizes socket by mains switch.When need using socket, turn on the power switch, the sleeve in the socket is charged, time spent powered-down switch not, and the sleeve in the socket is not charged.In a single day this socket can solve the charged problem of sleeve, but forgets the powered-down switch, this protective effect then disappears automatically.Simultaneously this socket uses neither be very convenient, be in the past to be communicated with power supply with socket by plug only to need a step just can finish, and this socket needs two steps just can finish.

(3) summary of the invention

Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides a kind of performance simple in structure, easy to use, safe high insertion plug-in socket.

The technical scheme in the invention for solving the technical problem is: a kind of insertion plug-in socket, comprise sleeve and power-supply circuit, also comprise live part, described live part is electrically connected with described power-supply circuit, described live part is provided with fixed contact, described sleeve is provided with a bending shell fragment, one end of described bending shell fragment is a stiff end, this stiff end and described sleeve are affixed, the other end is a free end, this free end be provided with can with the contacted armature contact of described fixed contact, the free end of described bending shell fragment is provided with the push pedal that can stretch in the described sleeve and place described sleeve socket below, and described push pedal is provided with the oblique surface of meeting to described sleeve socket.

The stiff end of described bending shell fragment and the riveted joint of described sleeve.Bending shell fragment and sleeve are well linked together, and riveted joint simultaneously can not take very big space yet, can reduce the volume of conductive component, thereby make socket become smaller and more exquisite.

Further improve, the stiff end place that is positioned at described bending shell fragment on the described sleeve extends upward and is provided with a catch, and this catch is relative with described push pedal.This catch can support the inserted sheet of plug, and the thrust of push pedal is offset on the shell fragment in order to avoid inserted sheet is because of being bent, and causes bending armature contact on the shell fragment and the fixed contact loose contact on the live part, thereby influences the performance of socket.

The utility model in use, the inserted sheet of plug is inserted in the sleeve, inserted sheet contacts with the oblique surface of push pedal, oblique surface generation thrust to the right through push pedal, push pedal moves right, bending shell fragment simultaneously moved right by thrust generation distortion, with inserted sheet in the process that sleeve bottom presses down, armature contact on the bending shell fragment separates with fixed contact all the time, thereby sleeve is not charged, can not cause electric shock accidents even touch inserted sheet yet, insert in the sleeve fully up to inserted sheet, thereby push push pedal to low order end, and the armature contact of bending on the shell fragment contacted with fixed contact on the live part, with the circuit communication between live part and the sleeve, socket enters the energising operating state; When the inserted sheet of plug was extracted in sleeve, under the effect of restoring force of bending shell fragment, the armature contact on the bending shell fragment was away from the fixed contact of live part, thereby makes sleeve no longer include.Because sleeve do not have electricity,, can not get an electric shock so, directly or indirectly run into to be exposed to outer plug slice by staff even when plug slice is not extracted socket fully yet.

The beneficial effects of the utility model are: because sleeve is not directly to be communicated with power supply, before the inserted sheet of plug inserted sleeve fully, sleeve was can be not charged, thereby just can not cause electric shock accidents.This conductive component should be in socket, and this socket is as long as action can be finished energized once the step, very convenient as common socket.The utility model is simple in structure, protection against electric shock is effective.
