Abstract

The disadvantages of the socket sold in the market are as follows; firstly, the jack of the socket easily makes children be electrically shocked; secondly, the conductive contacting copper sheet of the socket adopts the forming type; after the conductive contacting copper sheet of the socket is used for a long time, the elasticity is decreased, which causes bad contact; the conductive effect is damaged. According to the two disadvantages, the socket of the utility model has two innovations on the structure; (1) the jack is changed into the closed type, which makes the inner conductive copper element thoroughly insulated with the outside; (2) the original forming contacting copper sheet is changed into a movable spring copper sheet, which can ensure that the contact is permanently good.

Description

Safety socket with closed jack

Safety utilization of electric power is that every electrical appliance is necessary for the prerequisite that the user considers in the use, but the socket of being sold in the market, its jack provides the chance of electric shock accidents sometimes to child, and for this reason, the structure to existing socket is necessary to be further improved.Its improved method has a lot, but good from safe effect, produces every imaginations such as the few and cost province of easy, mfg. moulding die, and it is optimum having only with the closed pore formula.Jack is after closing, can thoroughly completely cut off anything contacts with inner conductive copper spare, this new product is in the formality of perforate, design has simple tricks of the trade, promptly must will stir " change " of " closed pore sheet " earlier, press into about two millimeters forward after, can turn push jack aside, child does not know tricks of the trade, just can not perforate.

In addition, this product will be conducted electricity again and be contacted copper sheet, by the shaping type of consistent use, change the movable spring formula into, and the former is after the typing copper sheet successively decreases with tired elasticity for a long time, and with regard to loose contact, the latter can guarantee that then contact is permanent good.This is the initiative on the socket production history.

Description of drawings:

Fig. 1, closed pore safety socket overall structure cutaway view and profile vertical view thereof.In the last figure each in addition part name be called (1) base, (2) change, (3) closed pore sheet, (4) cover, (5) and be subjected to insert frame, (6) movable contact flat, (7) contact spring, (8) pin, (9) terminal block (10) heading spring, (11) steel ball.

Fig. 2, change (the part numbering 2 in addition), (front view) change inner ring has four wealthy 2.5 millimeters grooves, for other part numbering 9, wealthy 2 millimeters projections on two terminal blocks have embedded the pinning effect, when change being pressed down about 2 millimeters, begin out of stock to along or counter rotation moving, stir the closed pore sheet.

Fig. 3, terminal block (the part numbering 9 in addition).The little figure that the front view right side replenishes is an extended partial right side view on the line of symmetry, reflects wealthy 2 millimeters projections that hang down, and is the structure of pinning change.

Claims

A kind of closed pore safety socket, have base (1), cover (4), it is characterized in that it also has change (2), closed pore sheet (3), formed by slotting frame (5), movable contact flat (6), contact spring (7), pin (8) terminal block (9), heading spring (10) and steel ball (11).It is become a kind ofly reach safe new structure by closing jack.
