Abstract

The utility model provides a safety socket. A slide insulating base is arranged in a casing. A couple of contact conductance plates are arranged on the bottom surface of the slide insulating base. The internal conductive clip of a plug jack arranged in the contact conductance plate is extended to the bottom part of the casing and forms a hinge flap. When the plug terminal is correctly inserted, the slide insulating base can be pressed, and then the contact conductance plate under the slide insulating base and the hinge flap are conductively contacted, therefore the clip body above the conductive clip can contact with the inserted plug terminal to provide power supply to the electronic products. When the plug jack is incorrectly inserted or metallic foreign body is inserted, the current conduction can not be performed.

Embodiment

See also Fig. 1 and Fig. 2, the utility model provides a kind of safety socket, and the terminal of the sub-product plug of powering is to inserting to obtain power supply.Safety socket 1 is mainly constituted with a shell 2, an electric wire 13, at least one pair of conductive clip 7, at least one slip insulating base 3 and at least one pair of power supply contact 6.

Shell 2 is formed with upper shell 21 and lower house 22, and having at least on it can be for 23 pairs of the jack of 91 pairs of insertions of a plug 9 terminals, and the logarithm of 23 pairs of jacks can design as required, for example shown in Fig. 1 is two pairs; 24 point midways with respect to 23 pairs of jacks extend a spring cylinder base 25 to shell 2 from the bottom, accommodate the lower portion of a spring 8 in the described spring cylinder base 25; Can further be provided with a guide pillar 26 that is supported in the middle of the spring 8 in the spring cylinder base 25.Electric wire 13 terminal connections one can obtain the plug 131 of power supply, and extend in the shell 2.

Conductive clip 7 is provided with in pairs, and the logarithm of described conductive clip 7 is to establish according to the logarithm of 23 pairs of jacks, and is arranged in the shell 2 by 23 pairs of relative jacks; The clamp 71 of each conductive clip 7 is set in wherein the jack 23, and has the tabs 72 that extends to shell 2 bottoms 24, and a side of at least one clamp 71 is established a shrinkage pool 74.

The number of slip insulating base 3 is to establish according to the logarithm of 23 pairs of jacks, and has a level board 31, upwards forms a cylindrical shell 32 in the middle of it, and described cylindrical shell 32 at least one sides are provided with a salient point 321, and described salient point 321 is established a shrinkage pool 74 with a side of clamp 71 and is opposite face; The described relatively tabs 72 to conductive clip 7 in described level board 31 bottom surfaces is provided with a pair of contact conducting strip 4; And described cylindrical shell 32 internal diameters are greater than spring cylinder base 25 external diameters, and described cylindrical shell 32 is accommodated the position, top of spring 8, makes when normality, described contact conducting strip 4 are kept not contacting with described tabs 72 is separated.

Power supply contact 6 is provided with in pairs, its logarithm is to establish according to the logarithm of 23 pairs of jacks, separated being arranged in the shell 2 is connected with electric wire 13 conductions, and is connected to the described to contacting conducting strip 4 of slip insulating base 3 level boards 31 bottom surfaces with what a soft guide card 10 conducted electricity respectively.

In addition, described to the contact conducting strip 4 extend a pair of first make contact 5, and described tabs 72 extending a pair of second contact point 11, described first make contact 5 contacts with described second contact point 11 when slip insulating base 3 is pressed down, and contact conducting strip 4 is conducted electricity with tabs 72 contact.Be provided with a pair of contact site 12 above the level board 31 of slip insulating base 3, described contact site 12 contacts respectively with 91 pairs of plug terminals that insert.

See also Fig. 3, the utility model in use, the terminal 91 of plug 9 is inserted in the jack 23 of shell 2, to contacting with the contact site 12 of slip insulating base, and make slip insulating base 3 can be pressed down (shown in arrow among the figure), it is fixing to make that the salient point 321 of cylindrical shell 32 1 sides combines with the shrinkage pool 74 of a side of clamp 71, and the contact conducting strip 4 of below contact with tabs 72 conductions of conductive clip 7, makes described plug obtain the electronic product use of power supply for connection.

See also Fig. 4, when the utility model fails correctly to insert at the terminal 91 of plug 9, when for example only a terminal 91 inserts jack 23 shown in the figure, because stressed inequality on the level board 31 of slip insulating base 3 and tilt (direction shown in arrow among the figure), make cylindrical shell 32 to block and can't press down with spring cylinder base 25, then contact conducting strip 4 nothings and contact with tabs 72 conductions, then conductive clip 7 can not produce electric current, does not have the danger of getting an electric shock.

The person of advancing, referring to Fig. 5, the utility model is on structural design, level board 31 can be formed a slotted hole 33 in contact site 12 other plug terminal 91 insertion positions relatively, and described to first hollow bulb 41 of contact conducting strip 4 formation areas greater than the area of described slotted hole 33, and described to second hollow bulb 73 of tabs 72 formation areas greater than the area of described slotted hole 33.Such design will make metallic foreign body when inserting jack 23, can pass slotted hole 33, first hollow bulb 41 and second hollow bulb 73, and can not move down with making slip insulating base 3, also can not contact, so will can not conduct electricity after the metallic foreign body insertion, to reach safe effect with contacting conducting strip 4.When this especially inserts metallic foreign body to children, can provide the protection effect.

Situation when elongated shape metallic foreign body 92 inserts has been described in Fig. 6.After metallic foreign body 92 inserts jack 23, can take place to contact or discontiguous situation with the clamp 71 of conductive clip 7 tops.Because metallic foreign body 92 can pass slotted hole 33, first hollow bulb 41 and second hollow bulb 73, can not press down slip insulating base 3, then contacting conducting strip 4 can not contact with tabs 72 conductions, therefore on conductive clip 7, there is not electric current, even metallic foreign body 92 contacts with described conductive clip 7, there is not the danger of getting an electric shock yet.

Situation when in addition, 93 insertions of ㄩ shape metallic foreign body being described in Fig. 7.After ㄩ shape metallic foreign body 93 inserts two jacks 23, can take place to contact or discontiguous situation with the clamp 71 of two conductive clips, 7 tops.Because ㄩ shape metallic foreign body 93 can pass slotted hole 33, first hollow bulb 41 and second hollow bulb 73, can not press down slip insulating base 3, then contacting conducting strip 4 can not contact with tabs 72 conductions, so on conductive clip 7, do not have electric current, even ㄩ shape metallic foreign body 93 is in contact with it, there is not the danger of getting an electric shock yet.

To sum up institute is old, safety socket innovation structure provided by the utility model, making only has after plug terminal is to correct insertion jack, just can obtain power sub-product of power supply uses, but when undesired insertion or the insertion of other metallic foreign bodies, do not have electric current and pass through, do not have the unexpected danger that takes place of getting an electric shock naturally, meet the utility model of patent requirement fully, file an application in accordance with the law.
