Description

The folding attaching plug of pin

[technical field]

The utility model relates to a kind of attaching plug, particularly relates to a kind of folding attaching plug of pin of packing and carrying of being easy to.

[background technology]

Many weeks, attaching plug is the power source conversion device that connects power supply and power consumption equipment, it also is one of the most frequently used device of electric equipment.Traditional plug, its pin is fixed as one with plug body, and under obsolete situation, particularly pin is worn and torn or collision deformation easily in packing, transportation and sales process, causes the loose contact when using, and brings potential safety hazard.Because the pin of traditional plug is fixed, thereby, in packing, transport and carry and take up space morely in the process, and, cut packaging bag easily because its pin is outwards to give prominence to.

[summary of the invention]

The utility model is intended to address the above problem; and a kind of not frayed or collision deformation of pin of protecting when not using is provided, thus guarantee that pin and the good of socket contact in use, and do not occupy redundant space; packaged convenience, the folding attaching plug of the pin that is easy to carry about with one.

For achieving the above object, the utility model provides a kind of pin folding attaching plug, it comprises plug body and is located at pin on the plug body, this pin comprises at least two folding pins, one end of pin respectively with plug body in fixed head be rotatably connected, and be connected with power line, on the upper shell of plug body, be provided with the through hole that is complementary with the pin profile, this attaching plug is when user mode, and pin is perpendicular to the upper shell surface of plug body; Attaching plug can rotate pin 90 degree and be placed in the described through hole when non-working condition.

Pin link end is fixed with a vertical with it pivot.

One side of fixed head is provided with and the corresponding stopper slot of pin shape and position, and an end of stopper slot is provided with the pivot channel that the installing pin is used.

One end end of the through hole of plug body is provided with one can pull the depression that pin is used for finger.

The link end of pin contacts with the metallic conduction sheet, and conducting strip then is connected with the power lead that is connected to circuit board, and the pivot of described pin is installed in the pivot channel of pairing stopper slot rotationally, makes pin to rotate around pivot channel.

Circuit board is provided with USB interface.

Good effect of the present utility model is, it efficiently solves that present ubiquitous attaching plug pin under obsolete situation is worn or collision deformation and occur the problem of loose contact in use.Because pin is folding, when not in use, pin is folded in the stopper slot corresponding with it, can protect pin to avoid wearing and tearing or collision deformation.The utility model also has simple in structure, characteristics such as popularization easy to implement and extensive.

[embodiment]

The following example is to further explanation of the present utility model and explanation, and the utility model is not constituted any limitation.

Consult Fig. 1, the folding attaching plug of pin of the present utility model comprises pin 10, plug body 20, fixed head 30, power lead 40, metallic conduction sheet 50 and circuit board 60.

Described plug body 20 is dismountable housing, by upper shell 21 and lower house 22 involutory being formed by connecting.Described upper shell 21 is provided with the strip through hole 211 that is complementary with the pin profile, in this example three through holes, wherein an end end corresponding with the pin free end of two symmetrical through holes is provided with one and can pulls the depression 212 that pin is used for finger, and another through hole is provided with depression 213.One end end of plug body 20 is provided with a breach 23 that matches with USB interface 61 on the circuit board 60.Main points of the present utility model are that described pin 10 is that the cross section is rectangular columnar metal body, and its link end is fixed with a vertical with it pivot 11, and the two ends of pivot protrude in the pin side surface.Described fixed head 30 is the plate bodys that match with the plug body interior shape, the one side is provided with three and the corresponding stopper slot 31 of pin shape and position, stopper slot is to be formed by the sidewall 3111 that protrudes from the plate body surface, wherein an end corresponding with the pin link of the stopper slot 31 of two symmetries is provided with the pivot channel 311 that the installing pin is used, and another stopper slot 31 is provided with the pivot channel 312 with spline structure.The pivot 11 of pin 10 is installed in the pivot channel 311,312 of pairing stopper slot 31 rotationally, makes pin 10 to rotate around pivot channel 311,312.Pin link end contacts with conducting strip 50, and conducting strip then is connected with the power lead 40 that is connected to circuit board 60.Described power lead 40 is connected on the circuit board 60 after passing two through holes 32,33 of fixed head one end.Circuit board 60 has a USB interface 61, and USB interface 61 can be external to power consumption equipment with attaching plug.As shown in Figure 2, the free end of pin 10 passes and reaches outside the plug body 20 from the through hole 211 on the upper shell 21, and pin 10 links contact with conducting strip 50, and 50 of conducting strips are connected with the power lead 40 that passes fixed head 30 and be connected to circuit board 60.
