Description

Mechanical self-latching safety pin socket

The utility model relates to and has the pin socket coupling device technical field that the two poles of the earth are connected with additional ground protection.

The plug socket of Chu Shouing exists a series of potential risk owing to be not provided with mechanical self-latching structure and protection against electric shock structure in the market.When children blindly insert jack with conducting objects, very easily get an electric shock, have plug the time touch reveal electric position and get an electric shock dead, have because of loose contact damages household electrical appliance, influence microcomputer normally to use, what have causes fire disaster because of sparking.In addition, existing socket is used two-wire system more, can't ground connection, and use electric planer, electric hand drill, electric tools such as electromagnetic shaker for building can't ground connection human body to be produced the short circuit accident that causes death because of electric leakage often.In sum, the electric leakage, outage, the loose contact that exist of pin socket at present, strike sparks, come off, easily problem such as electric shock never is solved so far.

The purpose of this utility model provides a kind of mechanical self-latching safety pin socket, has to use reliable, convenient, safe characteristics, the generation of accident such as can prevent from effectively to leak electricity, outage, loose contact, sparking, electric shock, plug come off.

The utility model is achieved in that a kind of mechanical self-latching safety pin socket, comprise Three-hole socket box and three latches, it is characterized in that socket box jack place is provided with insulation retaining orifice plate, be provided with latch post position and lock mechanism in socket box or on the latch, latch post links to each other with power line, ground wire or zero line by the metallic conductor of corresponding locking mechanism.

Position and lock mechanism is contained in the socket, with the jack corresponding position insulation sealing tube that moves up and down is arranged, and socket box is provided with sealing tube rail plate, is provided with the compression spring in the sealing tube; Be provided with the elastic metallic pin on the horizontal direction near the sealing tube, pin is provided with guide rail, the back is provided with the compression spring, pin and power line or ground wire, zero line link to each other, the corresponding position is provided with an insulation button above the box, establishes an inclined-plane below the button, and the inclined-plane that links to each other with pin cooperates, latch post is provided with the position and lock groove, and latch box or sealing tube are provided with latch post and insert to rock-steady structure.

Be provided with insulation sealing spring strut below live wire and the zero line jack, the position and lock button has one, link to each other with two horizontal resiliency pins, two elasticity pins and live wire latch post and zero line latch post match, and are provided with the metallic elastic tube that links to each other with ground wire below the ground wire jack.

The location locking mechanism also can be located on socket and the latch, an insulation push-and-pull piece along guide rail movement that fixes with the ground wire inserting column is arranged on the latch, the push-and-pull piece is provided with detent mechanism, on socket, one metallic elastic tube is arranged with ground wire inserting column corresponding position, the elasticity tube links to each other with ground wire, one up big and down small bullet is housed on the elasticity tube, and respectively there is a latch location bull stick that sways on the bullet both sides.Latch post is provided with the position and lock groove, and plug housing is provided with plug-type jack insulation barrier.

Detent mechanism on the push-and-pull piece can be a manual night bolt post, and jack is on latch body, or structure such as convex-concave locate mode.

Characteristics of the present utility model are; Use reliable, convenient, safety, the generation of accident such as can prevent from effectively to leak electricity, outage, electric shock, sparking, loose contact, plug come off, simple and reliable for structure, be fit to apply.

Be described further below in conjunction with embodiment, but not as to qualification of the present utility model.
