DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] like Figures 1 to 13 As shown, the magic cube socket of the present invention comprises a housing 1, a retaining member 2, an insulating member 3 and a conductive component 4. The retaining member 2 is used for installing the insulating member 3, so that the insulating member 3 can be fixed on the retaining member 2, and when the insulating member 3 is inserted with the insertion rod 5, the contact plate 6 on the insulating member 3 can be pushed by the insertion rod 5, so that the insertion rod 5 passes through the notch 7, and the arc-shaped portion 8 in the notch 7 generates friction with the surface of the insertion rod 5, thereby limiting the position of the insertion rod 5, and the insertion rod 5 is squeezed and fixed in the notch 7 by elastic force, so that the insertion rod 5 will not be easily separated. The conductive component 4 is arranged at the rear end of the insulating member 3, and the retaining insertion rod 5 passes through the insulating member 3 after being inserted, so that it contacts the conductive component 4. When contacting with the conductive component 4, the insertion rod 5 needs to be fully inserted, so that the elastic member 9 in the conductive component 4 is pushed to deform under force, so that the insertion rod 5 can contact the conductive column 10 through the elastic member 9.

[0019] A cover 11 is provided at the upper end of the housing 1. The interior of the cover 11 is hollowed out. A coil can be provided inside the cover 11 to achieve wireless charging. The contact method between the wireless charging structure and the first power terminal 12 and the second power terminal 13 can adopt the power-on method of the conductive column 10, and power-on can be achieved by direct insertion.

[0020] The housing 1 is provided with a lip 14, which can be directly inserted into the cover 11 to install the cover 11. The lip 14 can be installed by a snap-fit ​​structure or by bonding to fix the cover 11 on the housing 1.

[0021] An integrated plug 15 is provided at the lower end of the housing 1, and a plug rod 5 is provided on the plug 15, so that multiple sockets can be plugged in. The housing 1 is hollowed out to form an installation chamber 16, and an insulator 17 is provided in the installation chamber 16. The insulator 17 is composed of a mounting portion 18 and a fixing portion 19, and the fixing portion 19 is located at the upper end of the mounting portion 18. A conductive column 10 is also provided on the mounting portion 18, and the conductive column 10 is arranged at the four corners of the fixing portion 19. The conductive column 10 is connected to the plug 15. When the conductive column 10 is connected to the plug rod 5 of the plug 15, a connecting guide rod (not shown in the figure) can be arranged inside the mounting portion 18 to achieve the connection between the conductive column 10 and the plug rod 5. When the plug 15 and the housing 1 are manufactured, they are integrally formed, and the plug rod 5, the connecting guide rod and the conductive column 10 are wrapped by the insulator 17. Since the electrodes of the adjacent conductive columns 10 are opposite, the electrodes on the diagonal portions of the fixing portion 19 are the same, so that the first electrical terminal 12 and the second electrical terminal 13 are kept cross-vertically installed.

[0022] The fixing part 19 is provided with a vertically arranged diagonal groove 20, and the conductive pillars 10 are respectively arranged at both ends of the diagonal groove 20.

When the first power terminal 12 and the second power terminal 13 are inserted into the clamping opening 25, the clamping portion 24 and the clamping portion 24 clamp the first power terminal 12 and the second power terminal 13 to achieve power supply. In addition, an inclined guiding slope 26 is provided on the clamping portion 24 to guide the insertion of the first power terminal 12 and the second power terminal 13.

[0024] The retainer 2 is arranged on the inner wall of the installation chamber 16, and the housing 1 is provided with a plurality of docking portions 27 for matching with the plug 15, and the middle of the docking portion 27 forms a slot 28 for docking with the plug 15. The retainer 2 is composed of a bottom plate 29 and side plates 30 symmetrically arranged on both sides of the bottom plate 29, and the middle of the retainer 2 is hollowed out to form an active area 31, and the side plates 30 are provided with symmetrically arranged first installation openings 32, and the bottom plate 29 is provided with symmetrically arranged second installation openings 33.

[0025] The insulating member 3 is arranged in the retaining member 2, and the insulating member 3 is composed of a fixing plate 34, a deformation plate 35, a contact plate 6, an extrusion plate 36 and a blocking plate 37. The fixing plate 34, the contact plate 6 and the deformation plate 35 are arranged vertically, and the fixing plate 34 and the contact plate 6 are arranged parallelly. The contact plate 6 contacts the docking portion 27, and the contact plate 6, the extrusion plate 36 and the blocking plate 37 are placed in the active area 31 through the first installation opening 32. A third installation opening 38 matching the second installation opening 33 is provided in the middle of the fixing plate 34.

[0026] A notch 7 is provided in the middle of the extrusion plate 36, and an arc portion 8 is provided in the notch 7, and the arc portion 8 connects the contact plate 6 and the blocking plate 37. The arc portion 8 is used to keep the arc portion 8 from being squeezed by the insertion rod 5 after the insertion of the insertion rod 5, so that the arc portion 8 is deformed, so that the deformed arc portion 8 exerts a reverse force on the insertion rod 5, so that the insertion rod 5 can be subjected to a larger friction force, and the plug 15 is prevented from falling out easily.

[0027] Symmetrical extension arms 39 are provided on both sides of the third mounting opening 38, and bending arms 40 are provided on the extension arms 39, and the bending arms 40 are in contact with the blocking plate 37. The extension arms 39 can keep the fixed plate 34 at the lower end of the second mounting opening 33, so that the positions of the third mounting opening 38 and the second mounting opening 33 correspond. At the same time, the blocking plate 37 subjected to force can be supported by the bending arms 40. When supporting, a punching hole 41 is formed in the middle of the extension arm 39, and a limiting arm 42 is provided in the punching hole 41, and the lower end of the limiting arm 42 is placed on the bottom plate 29. The pressure received by the bending arm 40 is transmitted to the limiting arm 42, so that the limiting arm 42 is supported by the bottom plate 29, so that the position of the blocking plate 37, the contact plate 6 and the arc portion 8 is maintained and will not be further pressed down, so that the insertion rod 5 can be subjected to a larger reverse force from the arc portion 8.

[0028] A deformation area 43 is formed between the contact plate 6 and the blocking plate 37. When the contact plate 6, the extrusion plate 36 and the blocking plate 37 are installed from the first mounting port 32, the blocking plate 37 and the extrusion plate 36 need to be squeezed into the deformation area 43 first, so that the angle between the extrusion plate 36 and the contact plate 6 is less than 90°, and then the contact plate 6, the extrusion plate 36 and the blocking plate 37 are inserted into the first mounting port 32.

[0029] A positioning groove 44 is provided on the side plate 30, and the end of the blocking plate 37 is placed in the positioning groove 44, so that after the arc portion 8 is pushed by the insertion rod 5, the end of the blocking plate 37 is kept in the positioning groove 44, thereby limiting the blocking plate 37 from being pushed further.

[0030] Under normal conditions, the symmetrically arranged extrusion plates 36 are in contact with each other. At this time, the width of the symmetrical notch 7 is smaller than the diameter of the insertion rod 5. Only after the insertion rod 5 is inserted, the insertion rod 5 is kept pushing the arc portion 8, and then the extrusion plates 36 are squeezed against each other, and the lower contact plate 6, the extrusion plate 36 and the blocking plate 37 are pressed down, the extrusion plates 36 are separated from the extrusion plates 36, and the end of the blocking plate 37 enters the positioning groove 44.

[0031] The conductive component 4 is installed inside the housing 1, and the conductive component 4 is provided at multiple locations and is installed around the annular body 21. The conductive component 4 is provided with a first power terminal 12, a second power terminal 13, a power post 45, an elastic member 9 and a fastener 46. The first power terminal 12 and the second power terminal 13 are installed in the diagonal groove 20 in a vertically crossed manner, the power post 45 is arranged in the sliding hole 23, one end of the power post 45 is in contact with the first power terminal 12 and / or the second power terminal 13, the elastic member 9 is installed on the other end of the power post 45 through the fastener 46, and the elastic member 9 is in contact with the annular body 21.

[0032] Both ends of the first power terminal 12 and the second power terminal 13 are provided with vertically arranged contact portions 47. When the insertion rod 5 is inserted, the contact portion 47 is in contact with the power post 45. Only after the insertion rod 5 is kept, the insertion rod 5 pushes the fastener 46, so that the fastener 46 pushes the elastic member 9, and the elastic member 9 pushes the power post 45, so that the power post 45 contacts the contact portion 47, and the elastic member 9 is deformed by the force, and the contact arm 48 is bent and lifted upward, so that the contact arm 48 contacts the insertion rod 5, thereby achieving power supply.

[0033] The ground terminal can be installed on the ring body 21 and located between the two elastic members 9, but not in contact with the two elastic members 9. An insulating block can also be provided on the ring body 21 for isolation.

[0034] A bending section 49 is provided in the middle of the first power terminal 12, and a placement opening 50 for placing the second power terminal 13 is formed in the middle of the bending section 49. The placement opening 50 can prevent the first power terminal 12 and the second power terminal 13 from contacting each other, resulting in contact between the "neutral line" and the "live line".

[0035] The insertion rod 5 of the plug 15 is inserted into the slot 28, and the insertion rod 5 is kept to push the symmetrical contact plate 6 into the second installation port 33 and the third installation port 38, pushing the fastener 46 to keep the elastic member 9 deformed, and the power post 45 slides in the sliding hole 23, keeping the power post 45 in contact with the first power terminal 12 and / or the second power terminal 13 to be energized. The elastic member 9 is deformed under the extrusion of the fastener 46, keeping the two ends lifted up to contact with the insertion rod 5 to be energized.

[0036] The fastener 46 is composed of a pushing portion 51 and a threaded portion 52. A threaded hole 53 matching the threaded portion 52 is provided in the middle of the connecting post 45. The fastener 46 is made of insulating material.

[0037] The elastic member 9 is composed of a pressure-applying portion 54, a force-bearing portion 55, an elastic portion 56 and a contact arm 48. A through hole 57 for accommodating the power connection post 45 is provided in the middle of the pressure-applying portion 54. The pushing portion 51 is placed on the pressure-applying portion 54. The elastic member 9 is restricted to the outside of the annular body 21 by the fastener 46. An elastic fulcrum 59 is formed between the elastic portion 56 and the contact arm 48. The elastic portion 56 is arranged in an arc shape. A contact area 58 is formed between the contact arms 48.

[0038] like Fig.13 As shown, before the fastener 46 is pushed by the external force F1, the elastic fulcrum 59 is located on the outer wall of the annular body 21. When the fastener 46 is pushed downward, the external force F1 on the pressure-applying portion 54 causes the pressure-applying portion 54 and the force-bearing portion 55 to press downward. At this time, the force-bearing portion 55 and the outer wall of the annular body 21 are in an inclined state. When the force-bearing portion 55 contacts the outer wall of the annular body 21, the elastic portion 56 is forced to flip upward, thereby driving the contact arm 48 to lift upward, so that the contact arm 48 contacts the insertion rod 5. At the same time, the contact arm 48 is provided with an arc surface 60 that matches the insertion rod 5.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
