Description

A kind of protection against electric shock termination

Technical field

The utility model is a kind of protection against electric shock termination, this device belongs to daily electrical connection arrangement.

Background technology

The use of plug and socket is very universal in daily life, but common plug and socket is substantially conductive gold Belong to exposed or half is exposed（It is readily accessible）, user（Especially infant）It is easy to surprisingly touch electric conductor and cause Electric shock accidents；In addition, common socket is susceptible to loosening and leads to poor contact after being used for a long time.

Invention content

The utility model realizes connecting component conductive metal mainly solving the technical problems that a pair of of plug and socket of design It is built-in, prevent accidental shock purpose to reach.The utility model connects and cut-out circuit is convenient, it is firm to connect, and solves Poor contact problem caused by common socket loosens.

A kind of protection against electric shock termination, including plug, two big component of socket；Plug includes insulation crust（2）, binding post （3）, turntable（4）, inner core（5）, outer core（15）With fixed disk（6）, turntable and fixed disk pass through retaining ring（7）Connection；Socket packet Include jack housing（8）, binding post（9）, insulation crust（10）The contact and（13）.

The male component of the protection against electric shock termination, it is characterized in that：Plug bond column uses brass, with plug inner core It is structure as a whole, the two is fixed on commonly through glue on insulation turntable；Brass inner core uses and the outer core inner shape phase that insulate Same arc structure, the outer core that insulate are structure as a whole or are glued with the fixed disk of insulation；Fixed disk passes through axial locking ring with turntable Connection, can relatively rotate between the two.

The female component of the protection against electric shock termination, it is characterized in that：There are two structure sizes and insulation for jack housing The adaptable trepanning at 180 degree of outer core, jack connector column（9）, contact（13）With metal clips（12）It is structure as a whole, metal Shrapnel and socket aperture（14）It is glued to insulation crust at 90 degree（8）Inner wall on；The shell knot of the protection against electric shock termination Component, it is characterized in that：Plug body（2）With the insulation turntable after connecting lead wire（4）It is glued；When only there are one plugs for socket Kong Shi, socket insulation crust（10）With shell（8）It is glued；When socket has multiple rows of plug hole, shell（10）Spiral shell can be passed through Nail and shell（8）It is attached.

The advantageous effect of the utility model compared with the prior art is：All conductive metals are all made of embedding structure, Yong Huwu Jack is encountered in meaning, being even inserted directly into socket aperture will not all get an electric shock, and after being attached using matched plug, it is only necessary to One angle of plug turntable rotation, which can be realized, to be reliably connected；Due to there is rotation process, it can make plug inner core（5）With socket Contact（13）It is in close contact, is less prone to poor contact phenomenon caused by ordinary plug is used for a long time.

Specific implementation mode

Specific embodiment of the present invention is further described below in conjunction with attached drawing.

The relative position of the utility model protection against electric shock termination is as shown in Fig. 1, includes mainly plug and socket two Component.Male component includes insulation crust（2）, binding post（3）, turntable（4）, plug inner core（5）, the outer core of plug（15）, it is fixed Disk（6）And retaining ring（7）；Female component includes jack housing（8）, jack connector column（9）, metal clips（12）, contact（13） And insulation crust（10）；Insulation crust（2）, binding post（3）, turntable（4）It is glued together, outer core（15）With fixed disk（6）Glue It is connected together, plug inner core（5）With binding post（3）Be structure as a whole, plug inner core with outer core（15）Interior shape size It is adapted（It is arc structure）, turntable（4）With fixed disk（6）Pass through retaining ring（7）Carry out axially position；Jack housing（8） Socket aperture there are two opening（14）, two socket apertures are uniformly distributed for 180 degree, and are adapted with cored structure size outside plug；Metal clips （12）With socket aperture（14）90 degree of distributions each other, metal clips（12）Centre position is equipped with socket shrapnel contact（13）It is connect with socket Terminal（9）, lead for public use can pass through binding post（9）It connects；Insulation crust（10）Shape can be converted according to use condition, it is such as round （Fig. 1）, it is rectangular（Fig. 8）.

In actual use, plug passes through outer core（15）It is inserted into socket aperture（14）It is attached, then holds insulation crust（2） Being rotated by 90 ° reliably to power on, and working condition and its representative section are as shown in attached drawing 3 and 5；Conversely, reversely rotating insulation Shell（2）It can make metal inside（5）The outer core of retraction insulation（15）, plug and socket firmly then can be realized axially outward Separation, working condition and its representative section are as shown in attached drawing 2 and 4.

Device real work principle is：When needing to connect, rotating insulated shell（2）Drive the metallic plug to link together Inner core（5）Rotation, metal inside is gradually via outer core（15）Opening expose, when plug inner core is gone to and socket shrapnel contact （13）It can guarantee reliable energization when reliable contacts, as shown in Fig. 7；When needing to disconnect, rotating insulated shell（2）Drive connection Metallic plug inner core together（5）It reversely rotates, metal inside is gradually via outer core（15）Opening retract outer core inner, when Plug inner core is gone to and socket shrapnel contact（13）It may make circuit to disconnect when disconnection, then can firmly make axially outward Plug is detached with socket, as shown in Fig. 6.

The utility model is powered on and two kinds of plug, plug conductive metallic in-laid sides by being inserted into, rotating two steps Formula realizes the raising of attachment device safety, it is possible to prevente effectively from electric shock accidents caused by the factors such as general idea；In addition, due to inserting Head, which must also rotate an angle, to be extracted, and metal clips can effectively compress plug, and the utility model can also avoid pine Poor contact phenomenon occurs caused by dynamic.

While there has been shown and described that the implementation example of the utility model, those skilled in the art can manage Solution：A variety of to these implementation example progress can change in the case where not departing from the principles of the present invention and objective, change, It replaces and modification, the scope of the utility model is limited by claim and its equivalent.
