Description

The spin safe supply socket of band circumvolve lock set kit

Technical field

The present invention relates to a kind of safety power source plug socket, especially for the safety power source plug socket of low-voltage electrical apparatus with circumvolve lock set kit.

Background technology

The supply socket of prior art, its design principle all are to adopt elastic copper sheet to clamp attaching plug to realize current lead-through.In a single day elastic copper sheet follows the string or is out of shape and just cause loose contact in this structure, and the conductive copper sheet of this socket is exposed outside by jack, uses and life is easy to generate electric shock accidents.Rotary safe socket patent No. ZL 002 293390 has solved the unsafe problems of existing receptacle sockets and conducting strip coordination substantially, but, this socket is the mistake rotation under non-working condition, as it is rotatable to insert a hole, the conventional socket binding post still can appear by the exposed drawback of jack, to people's the bigger hidden danger of personal safety formation.

Summary of the invention

The objective of the invention is to address the above problem, a kind of spin safe supply socket with circumvolve lock set kit is provided.The abnormal operation that promptly inserts a hole can not rotate.

Technical scheme of the present invention: the spin safe supply socket of band circumvolve lock set kit comprises case top lid, following of housing, jack rotating shaft, jack, right-angled trapezium electric conductor and binding post, at corresponding jack rotating shaft groove side circumvolve lock set kit is arranged, circumvolve lock set kit mainly comprises flexible member and the executive component that is driven by flexible member.

The described spin safe supply socket that has circumvolve lock set kit, its circumvolve lock set kit mainly comprises lock dog and the dialing spring on the fixed leg that is installed in the loam cake both sides, dialing spring one end is stuck in the case top lid side, the other end embeds lock dog, and the other end of lock dog snaps under the effect of dialing spring in the groove that inserts for plug in the jack rotating shaft.

The described spin safe supply socket that has circumvolve lock set kit, its lock dog snap in end towards the inclined-plane of rotating shaft direction in vertical direction with 20-45 ° of angle.

The inlet wire binding post of jack and socket certain angle that staggers when the invention has the advantages that non-working condition, and the inlet wire binding post is hidden in the inside of housing, and binding post is exposed.At this moment, the jack rotating shaft can not be rotated by two lock dogs are locked.During use, the plug copper sheet inserts pushes the lock dog insertion open, rotates a certain angle, and power supply can be connected.Can not rotate when inserting the abnormal operation in a hole, binding post can not expose in jack, and insert can not contact conduction connector and binding post, so thoroughly eliminated potential safety hazard.

Embodiment

As shown in the figure: 1. loam cake, 2. descend seat, 3. jack rotating shaft, 4. hollow centre post, 5. back-moving spring, 6. binding post, 7. dialing spring, 8. lock dog, 9. plug copper sheet, 10. right-angled trapezium electric conductor, 11. right-angled trapezium electric conductor end sockets, 12. jacks, 13. grooves, 14. fixed legs, 15. lock dog inclined-planes.

The embodiments of the invention accompanying drawings

Band rotational lock spin safe supply socket shown in Figure 1 is made up of 1 time seat of case top lid, 2 jack rotating shafts 3, circumvolve lock set kit; Jack rotating shaft 3 is inserted in down on seat 2 newels 4 by loam cake 1, and its hollow space is inserted a rotating shaft back-moving spring 5.Have a pair of groove 13 on jack rotating shaft 3 two sides for 9 insertions of plug copper sheet.The double-vane that a pair of convex is arranged corresponding to the bottom portion of groove place.Respectively there is a square hole following seat both sides, and the binding post 6 with Y-axis angle 20 degree is housed on it.Form a right angle trapezoid space between binding post 6 and the rotating shaft 3, be inlaid with right-angled trapezium electric conductor 10 in it.

Fig. 3 is the circumvolve lock set kit structural representation, and Fig. 4 is that the circumvolve lock set kit plug inserts view.As shown in the figure: circumvolve lock set kit is coaxial dialing spring 7, the lock dog 8 of being equipped with on the fixed leg 14 of loam cake 1 inner both sides.The inner edge opening part that lock dog 8 contacts with jack rotating shaft 3 in the loam cake both sides snaps in the groove 13 that inserts for plug copper sheet 9 on jack rotating shaft 3 two sides.Lock dog 8 snap in end towards the inclined-plane 15 of rotating shaft direction in vertical direction with 20-45 ° of angle.Be beneficial to the insertion of plug copper sheet.

As Fig. 5, shown in Figure 6, lock dog snap in end towards the inclined-plane 15 of rotating shaft direction in vertical direction with 20-45 ° of angle.Be convenient to the insertion of plug copper sheet.

The operation principle of embodiments of the invention is achieved in that under non-working condition the rotating shaft 3 of jack is when initial position, and jack 12 has a certain degree with binding post 6 dislocation.At this moment, the lock dog 8 of circumvolve lock set kit snaps in inserting in the groove 13 for plug on the jack rotating shaft 3, and jack rotating shaft 3 can not rotate, and realizes that binding post is not exposed in jack.In use, when plug inserts, plug copper sheet 9 is pushed open by two lock dogs 8 that jack 12 will be stuck in the jack rotating shaft groove 13, be rotated, the right-angled trapezium electric conductor is lifted by the double-vane of a pair of band convex of bottom portion of groove, the back plug copper sheet 9 that puts in place closely contacts power turn-on by right-angled trapezium electric conductor 10 with binding post 6.When non-plug inserts, or the thruster piece 8 of unblanking, jack rotating shaft 3 can not rotate.When plug and jack rotating shaft 3 cycle initial positions, this moment, socket was in non-working condition again, had stopped binding post by the exposed situation of jack.

Fig. 1 ~ Fig. 6 has provided the embodiment of two pole sockets, and the structure of three pole sockets is removed the position difference of jack and circumvolve lock set kit, and its concrete structure and two spring hole scokets are identical.
