Embodiment
Below in conjunction with accompanying drawing and embodiment the attaching plug that the present invention's 360 degree rotate is described further:
Shown in accompanying drawing 1 to 8, the attaching plug of this 360 degree rotation comprises the plug casing of being made up of cover 1 and drain pan 2, is provided with the holder 3 and rotating seat 4 of coaxial setting in the housing, and rotating seat 4 is provided with through hole 4a, 4b, 4c.Ground terminal 5, fire end 6 and zero terminal 7 as inserting terminal are plugged among corresponding through hole 4a, 4b, the 4c, and are axially fixed on the rotating seat along rotating seat 4.Concrete buckle 4d (shown in accompanying drawing 1, only showing a place) through being arranged on rotating seat 4 back sides, thus the upper and lower end face (shown in accompanying drawing 1) of rotating seat 4 is stretched out at the two ends up and down of ground terminal 5, fire end 6 and zero terminal 7 respectively.The upper surface of rotating seat 4 is provided with boss 4e; Cover 1 is provided with empty window 1a; This boss 4e just in time with pass through empty window 1a and match; In passing through empty window 1a, rotate freely, and because the step surface 4f at boss 4e place and the acting in conjunction of cover 1 inner face 1b, it is interior and can not spin off from the empty window 1a of passing through of cover 1 to make rotating seat 4 can be limited to cover 1.On the upper surface of holder 3 (promptly with rotating seat 4 opposing end faces), be provided with the annular conductive rings (outer ring conducting ring 10, centre circle conducting ring 11, inner ring conducting ring 12) of 3 concentric settings, also be provided with connecting pin (shown in accompanying drawing 3) on each conducting ring 10,11,12.The upper surface of holder 3 is provided with cannelure 3a, 3b, the 3c corresponding with three conducting rings 10,11,12; Corresponding conducting ring 10,11,12 is placed in corresponding cannelure 3a, 3b, the 3c; Each cannelure 3a, 3b, 3c be last to be respectively equipped with 3 jack 3d (shown in accompanying drawing 1) that the pin of being convenient to conducting ring 3a, 3b, 3c passes; 3 jack 3d are in circumferencial direction certain angle that staggers each other; Make things convenient for each connecting pin to be connected, and keep certain electrical safety distance simultaneously with corresponding power line.
After inserting terminal (terminal 5, fire end 6 and zero terminal 7) fixedly was plugged on the rotating seat 4, its lower end was respectively equipped with a contact chip 5a, 6a, 7a.Each conducting ring contacts with the contact chip of one of them inserting terminal lower end.In the present embodiment, the contact chip 5a of ground terminal 5 downwards, stretch out, contact with the upper surface of outer ring conducting ring 10; The contact chip 7a of zero terminal 7 downwards, extend internally, contact with the upper surface of inner ring conducting ring 12; The contact chip 6a horizontal expansion of fire end 6 directly contacts with the upper surface of centre circle conducting ring 11.Simultaneously, for the contact chip 6a that guarantees fire end 6 can not meet other conducting ring, the position of the fire end of installing on the rotating seat 46 is provided with a protruding 4ff, make that fire end 6 is installed after, be lower than ground terminal 5 and zero terminal 7 slightly.In order to reduce counterrotating frictional force between rotating seat 4 and the holder 3; In addition; Avoid the contact chip of each inserting terminal between other adjacent conductive ring, to produce contact; Therefore be provided with a plurality of strong point 4ee in the lower surface of rotating seat 4, the lower surface of strong point 4ee is a sphere, is supported on the upper surface of holder 3.In addition, in order to guarantee to keep excellent contact between each inserting terminal and the conducting ring, between holder 3 and drain pan 2, be provided with elastomeric element.This elastomeric element is a waveform shell fragment 8.After attaching plug assembles; Through screw cover 1 and drain pan 2 are fixed together; Applied certain precompression to waveform shell fragment 8 this moment, keeps good electrical contact thereby promote conducting ring 10,11,12 on the holder with contact chip 5a, 6a, the 7a of corresponding ground terminal 5, fire end 6 and zero terminal 7.
In addition; In order to prevent that holder 3 from deflecting in housing, therefore be provided with reference column 22 at drain pan 2 centers, reference column 22 is provided with position block 21; The center of holder 3 is provided with the hole 3e suitable with reference column 22, and limits the relative position of holder 3 and drain pan 2 position block 21.Simultaneously, on the sidewall of drain pan 2, be provided with positioning strip 23, the position corresponding with positioning strip is provided with and positioning strip 23 mutual chimeric groove 3f on the holder 3, and when holder 3 was installed in the drain pan 2, positioning strip 23 was corresponding with the groove 3f on the holder 3.Because holder 3 defines the degree of freedom that it rotates in a circumferential direction through positioning strip 23 and position block 21, only can move vertically, therefore under the effect of the waveform shell fragment 8 of holder 3 lower ends, can free floating, thus keep and the inserting terminal excellent contact.
