The utility model can eliminate hidden dangers of electric shock and prevent electrical equipment from being damaged due to overload.

Description

A kind of attaching plug and socket

Technical field

The utility model belongs to power connector, is specifically related to a kind of rotatable safety type plug and socket of power source.

Background technology

Because conductive socket exposes, when energized is inserted plug or deenergization and pulled the plug out of the socket, there is electric shock hidden danger in the plugs and sockets that connects power supply in the prior art.Attaching plug almost all adopts ordinary plug simultaneously, lacks protective effect when separate unit electrical equipment is transshipped, and also can cause the fuse melting phenomenon in the electric equipment.

The utility model content

The utility model discloses a kind of attaching plug and socket, its purpose is to overcome existing plug and socket of power source, has electric shock hidden danger owing to conductive socket exposes, and lacks the drawback of overload protection.The plug of the utility model design is with socket conducts or electricity when disconnecting, and the conducting strip of socket does not expose, and is hidden among the socket elimination electric shock hidden danger.A kind of safety plug is provided simultaneously, between pin and binding post, seals in protective tube, prevent the damage of electric equipment overload, avoid the separate unit apparatus failure to influence other electrical equipment.

A kind of plug and socket of power source is characterized in that:

A) plug: plug top is polygon column handle, and lower central connects a cylindrical inserting handle, and pin one and pin two are " L " shape cylinder, and perpendicular end places in the plug, and horizontal end stretches out cylindrical inserting handle; Wherein the perpendicular end of pin one directly connects with power-line terminal, and pin two perpendicular end brachymemmas are connected a protective tube between pin two perpendicular ends and the power-line terminal, and the two ends difference fixing spring of protective tube connection pin two and power-line terminal presss from both sides;

B) socket: jack housing is square housing, and top is socket cover, and the bottom is the socket base plate, and the middle circle that suits the cylinder inserting handle that is provided with is revolved, and described socket cover center has circular hole, and circular hole outwards is communicated with elongated slot along diameter; Described socket cover bottom and socket base plate upper surface and elongated slot are 90 and spend positions, respectively with each fixing a slice conducting strip of screw.

The position of the corresponding protective tube of described plug body is provided with protective tube and changes groove, to be convenient for changing protective tube.

Two of described conducting strips are overlapping up and down, the middle bent of conducting strip, last slice present arc, sheet is arc down down, forms metal sleeve 16, screws in energized to make things convenient for pin one and pin two horizontal ends.

The conducting strip of the utility model socket does not expose, and is hidden among the socket, and electric shock hidden danger is eliminated in the connecting and disconnecting of rotary connector control power supply; Increase a protective tube in the plug, solve because overload causes the damage of electric equipment and the fuse melting phenomenon in the electric equipment.It is simple in structure, and is with low cost, and the circuit that can be widely used in the home electric tool connects.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in detail.

A kind of attaching plug and socket, plug construction is as shown in Figure 1: plug top is polygon column handle 1, the utility model is selected quadrangle column handle, lower central connects a cylindrical inserting handle 2, pin 1 and pin 24 are " L " shape conducting post, perpendicular end places in the plug, and horizontal end stretches out inserting handle 2; Wherein the perpendicular end of pin 1 directly connects with power-line terminal 5, and pin 24 perpendicular end brachymemmas are connected a protective tube 6 between pin two perpendicular ends and the power-line terminal 5, and the two ends difference fixing spring of protective tube 6 connection pins two and power-line terminal presss from both sides 7; The position of handle 1 corresponding protective tube 6 is provided with protective tube and changes groove 8, to be convenient for changing protective tube;

Socket is as shown in Figure 2: jack housing 9 is square housing, and top is socket cover 10, and the bottom is a socket base plate 11, and the middle circle that suits the cylinder inserting handle that is provided with revolves 12, and described socket cover center has circular hole 13, and circular hole outwards is communicated with elongated slot 14 along diameter; Be 90 degree positions with elongated slot on described socket cover bottom and the socket base plate, respectively with each fixing a slice conducting strip of screw, described two conducting strips are overlapping up and down, the middle bent of conducting strip 15, last slice present arc, following sheet is arc lower, forms metal sleeve 16, screws in energized to make things convenient for pin one and pin two horizontal ends.

During use: the pin one of plug and pin two are inserted the back and revolve 11 along circle and revolve and turn 90 degrees downwards along socket cover hole, 10 garden and elongated slot 14, and pin one and pin two just in time are stuck in the metal sleeve 16, realize the firm connection of circuit.The metal sleeve 12 of socket does not expose, and is hidden among the socket, eliminates electric shock hidden danger.

When need changing protective tube, only need change the groove 8 and take out protective tubes and get final product, be convenient for changing from protective tube.
