Abstract

The utility model relates to a socket and plug with safe utilization performance, wherein the plug is arranged at two pin ends with contact points which can extend out of the body, the contact point compassion is controlled by an inner spring, two electrodes of the socket are respectively positioned at the hollow part of the insulation block two sides, when electricity is needed, the pin is plugged in the plugging hole and the contact point can be pressed in the plugging pin by the socket shell and insulation block. When the contact point reaches the socket hollow point, the contact point will be popped out of the pin body by the spring and contacts with the socket electrode to output current. If other conductor enters the plugging hole, the conductor will not contact the electrode since the conductor has no convex contact point, so that no current passes through the conductor, thereby guaranteeing safety.

Description

The safety plug socket

Technical field the utility model belongs to a kind of safe plug and socket.

The socket that background technology is generally used now, inner charged electrode is two foils, and controls its elasticity by spring, with flexibility that improves plug and the fiting property that contacts with pin on the plug.The metal tape electrode slice of this class socket is exposed among the jack of socket cover, easily by sheet metal except that plug or bonding jumper, electric current is derived outside the Socket casing unexpectedly, and causes electric shock, and accident meets accident.Pin on the plug is made up of two flat or round bonding jumpers, and socket contacts with the electrode of socket, with delivered current.Plug move or the electric wire moving process in, can become flexible and part is deviate from, become to be exposed to outer energized conductor, and become safe hidden danger.

The summary of the invention the purpose of this utility model provides a kind of safe and reliable plug and socket.

Solution of the present utility model is: two metal electrodes in the socket are in the depression of the both sides of collets, and two pin ends of plug are provided with in opposite directions can give prominence to pin armature contact outward, adapt with the metal electrode of socket, and the contractility of contact is controlled by spring.Electric current to be from socket, obtained, the supporting plug of socket therewith must be used.

Because of the metal electrode of socket within the depression of collets, if insert with other electric conductor such as bonding jumper, sheet metal, metal bar that can inject jack, they not have outstanding contact, do not reach the interior charged electrode that caves in, thereby guarantee its fail safe.And pin of the present utility model with socket cover, when collets contact, in the retractable pin of contact, inserts pin smoothly, and when being inserted into, the electrode in the outstanding contact of pin and the socket depression contacts, and electric current is delivered to electrical appliance by pin.

Description of drawings concrete structure of the present utility model in conjunction with the embodiments and accompanying drawing, further specifies as follows:

Accompanying drawing is a cutaway view of the present utility model.

(1) is two pins of plug among the figure; (2) Socket casing; (3) spring; (4) electrode; (5) collets; (6) contact.

The end of two pins 1 of specific embodiment plug is equipped with and can be given prominence to the outer armature contact 6 of pin, and the flexible of contact controlled by spring 3; When plug inserts jack, contact 6 and Socket casing 2, during collets 5 contacts, contact 6 compression springs 3, enter in the pin, when being inserted to the recess of collets 5, spring 3 ejects contact 6, contact 6 is contacted with charged electrode 4, make electric current pass through pin 1, arrive electrical appliance.

Claims (2)

1. safety plug socket, it is characterized in that: there is the contact (6) of an activity end of two pins (1) of plug, is located at respectively in the both sides depression of collets (5) with the belt electrode (4) of contact (6) corresponding socket.

2. safety plug socket according to claim 1 is characterized in that: a spring (3) is arranged in plug ends contact (6).
