Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to an ultra-thin miniature plug. Background Technology

[0002] Connectors are key components for connecting electrical appliances to power sources. Their core purpose is to create a conductive path, ensuring the safe transmission of current to the appliance and guaranteeing its normal operation. Their significance lies in: ensuring electrical safety through standardized design, avoiding risks such as short circuits and electric shocks; enhancing leakage protection through grounding pins and other structures, safeguarding user safety; and allowing appliances to move freely without fixed wiring, greatly improving convenience. They are the fundamental medium for connecting energy and equipment in modern electrified life, promoting the widespread adoption and standardization of electrical appliance use.

[0003] Ultra-thin miniature plugs achieve miniaturization through optimized structure and materials. The principle involves using thin conductive sheets and a compact insulation design to ensure current transmission and safety while reducing size. Their pin spacing follows standard specifications, with some models further thinning through folding and flat cable designs. Application scenarios include: socket installation in narrow walls or behind furniture; adaptation to ultra-thin electronic devices; saving luggage space during travel; avoiding space conflicts when multiple plugs share a power strip; and recessed installation of smart home devices.

[0004] In existing technologies, some ultra-thin miniature plugs are further thinned by folding, flat cables, etc., to cope with the installation of sockets in narrow walls or behind furniture. However, when installing the plugs, it is still difficult to adjust the cable layout and angle according to the situation when a person puts their hand into the gap, which makes it difficult to plug in. Therefore, an ultra-thin miniature plug is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an ultra-thin miniature plug, which aims to improve the problem in the prior art where it is difficult to adjust the wire layout and angle when installing the plug due to the difficulty of adjusting the wires and angle when a person puts their hand into the gap.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An ultra-thin miniature plug includes a carrier plate, inside which two or three prongs are installed. The prongs are either "L"-shaped or "T"-shaped and are formed by welding or direct bending. The bending or welding angle of the prongs is any angle between 60 degrees and 120 degrees. A rotating mechanism is installed on the outside of the three prongs. The rotating mechanism includes a chassis, the bottom of which is rotatably connected to the bottom of the carrier plate. A groove plate is fixedly connected to the bottom of the carrier plate. A rotating ring is slidably connected to the inner wall of the groove plate. A sliding ring is fixedly connected to the bottom of the rotating ring. A top cover is detachably connected to the top of the carrier plate.

[0008] As a further description of the above technical solution:

[0009] The adjustment mechanism includes a fixed plate, the top of which is fixedly connected to the bottom of the bearing plate. A rotating column is fixedly connected to the inner side of the fixed plate, and a rotating disk is fixedly connected to the outer wall of the rotating column. A limit groove is formed on the inner wall of the rotating disk, and a limit component is installed on the inner wall of the rotating disk.

[0010] As a further description of the above technical solution:

[0011] The bottom of the support plate is fixedly connected to a ball bearing, and the bottom of the ball bearing is rotatably connected to the top of the chassis.

[0012] As a further description of the above technical solution:

[0013] The top of the chassis is slidably connected to a plurality of ball bearings, and the bottom of the sliding ring is slidably connected to the bottom of the plurality of ball bearings.

[0014] As a further description of the above technical solution:

[0015] The limiting component includes a spring, one end of which is fixedly connected to the inner wall of the rotating disk, and the other end is fixedly connected to the inner wall of the limiting groove. A limiting ball is fixedly connected to the top of the spring.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the rotating column is rotatably connected to a toothed disc, and the outer wall of the limiting ball is engaged with the outer wall of the toothed disc.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by rotating the bearing plate, the rotation of the bearing plate drives the rotation of the rotating ring and the groove plate. At this time, the rotation of the groove plate drives the sliding ring to rotate.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1: Refer to Figures 1 to 3An ultra-thin miniature plug includes a carrier plate 1, inside which two or three inserts 3 are installed. Due to the use of "L"-shaped and "⊥"-shaped inserts, the shell part and the electrode part form a 90-degree angle, which makes it easy to turn the package, i.e. the upper and lower shells, into thin sheets. All electrodes are inserted into the socket, with the outer casing and power cord parallel to the socket. During use, the plug is flush against the socket, allowing items to be placed as close to the wall as possible without bending or colliding with the power cord, improving safety. The optimal structure for "L" and "⊥" shaped plugs is a 90-degree angle between the top and bottom. However, the angle may vary depending on the manufacturing process. A rotating mechanism 5 is installed on the outside of the three plugs 3. This mechanism allows for position adjustment when inserting the three plugs 3, facilitating insertion in confined spaces. The rotating mechanism 5 includes a base 51, whose bottom is rotatably connected to the bottom of a support plate 1, allowing the support plate 1 to rotate relative to the base 51. A groove plate 53 is fixedly connected to the bottom of the support plate 1, limiting the sliding trajectory of the rotating ring 52. The rotating ring 52 is slidably connected to the inner wall of the groove plate 53. The rotating ring 52 slides within the groove 53, causing the bearing plate 1 to rotate. A sliding ring 54 is fixedly connected to the bottom of the rotating ring 52. A top cover 2 is detachably connected to the top of the bearing plate 1. The sliding ring 54 connects the rotating ring 52 and the ball bearing 55, making the rotation smoother. The ball bearing 55 is fixedly connected to the bottom of the bearing plate 1, which reduces friction during rotation. The bearing plate 1 is supported on the chassis 51 by the ball bearing 55. The bottom of the ball bearing 55 is rotatably connected to the top of the chassis 51, allowing the bearing plate 1 to rotate around the ball bearing 55. The top of the chassis 51 is slidably connected to multiple balls 55, which are evenly distributed to improve the stability of the rotation of the bearing plate 1. The bottom of the sliding ring 54 is slidably connected to the bottom of the multiple balls 55. The balls 55 support the sliding ring 54, making the rotating ring 52 drive the bearing plate 1 to rotate more smoothly. The inner wall of the bearing plate 1 is provided with an installation groove 8, which provides an installation position for the insert 3. The bottom of the insert 3 is fixedly connected to the inner wall of the installation groove 8, so that the insert 3 is firmly installed in the bearing plate 1.

[0037] Example 2: Refer to Figures 4 to 8Two inserts 3 are equipped with an adjustment mechanism 4 on their exterior. The adjustment mechanism 4 can adjust the angle of the wire 6 when using the ultra-thin inserts 3, avoiding damage caused by frequent twisting of the wire 6. The adjustment mechanism 4 includes a fixing plate 41, which is used to fix the rotating column 43. The top of the fixing plate 41 is fixedly connected to the bottom of the support plate 1, so that the fixing plate 41 and the support plate 1 are stably connected. The rotating column 43 is fixedly connected to the inner side of the fixing plate 41. The rotating column 43 provides rotational support for the rotating disk 44 and the gear disk 452. A rotating disk 44 is fixedly connected to the outer wall of the 3. The rotating disk 44 is used to install the limiting component 45. The inner wall of the rotating disk 44 has a limiting groove 42, which provides installation space for the spring 451 and the limiting ball 453. The limiting component 45 is installed on the inner wall of the rotating disk 44. The limiting component 45 is used to engage the gear disk 452 and fix the adjusted angle. The limiting component 45 includes a spring 451, which provides elastic force to engage the limiting ball 453 with the gear disk 452. One end of the spring 451... One end of the spring 451 is fixedly connected to the inner wall of the rotating disk 44, and the other end is fixedly connected to the inner wall of the limiting groove 42, so that the two ends of the spring 451 are securely connected. The top of the spring 451 is fixedly connected to the limiting ball 453. The limiting ball 453 can engage with the teeth on the outer wall of the toothed disk 452 under the elastic force of the spring 451. The outer wall of the rotating column 43 is rotatably connected to the toothed disk 452. The toothed disk 452 can rotate around the rotating column 43, driving the sheath 7 and the wire 6 to rotate. The outer wall of the limiting ball 453 and the outer wall of the toothed disk 452 are mutually engaged. The limiting ball 453 engages with the teeth of the gear plate 452, fixing the angle of the gear plate 452 after rotation. The bottom of the plug 3 is fixedly connected to the wire 6, which is used to transmit current and connect the plug 3 to the electrical equipment. The outer wall of the wire 6 is fixedly connected to the sheath 7, which can protect the wire 6 and drive the gear plate 452 to rotate. The two sides of the sheath 7 are fixedly connected to the gear plate 452. The two sides of the gear plate 452 cooperate with the limiting component 45, so that the angle can be fixed after the sheath 7 rotates, which makes it easy to adjust the insertion position of the wire 6.

[0038] Working principle: When the three-hole insert 3 is needed, due to the principle of left neutral, right live and top ground, the shape of the insert plate needs to be installed for insertion. This makes it difficult to adjust the position by hand when inserting the three-hole insert 3 in a narrow space. At this time, the support plate 1 can be rotated. The rotation of the support plate 1 drives the rotation ring 52 and the groove plate 53 to rotate. The rotation of the groove plate 53 drives the sliding ring 54 to rotate. Since there are multiple ball bearings 55 at the bottom of the sliding ring 54, the support plate 1 will rotate on the top of the chassis 51. This makes it easier for personnel to adjust the angle between their hand and the support plate 1, thereby achieving the purpose of easy insertion.

[0039] When using ultra-thin inserts 3, some inserts 3 need to be inserted into narrow spaces. This requires frequent twisting of the wire 6 to facilitate insertion into these narrow spaces. Frequent twisting of the wire 6 can damage the outer shell of the wire 6, resulting in poor contact. In this case, the sheath 7 can be rotated when inserting the wire 6, causing the sheath 7 to rotate the internal wire 6. The rotation of the sheath 7 will cause the gear plate 452 to rotate. Then, the limiting ball 453 will engage with the teeth on the outer wall of the gear plate 452 through the action of the spring 451, thereby adjusting the angle between the sheath 7 and the support plate 1, thus achieving the purpose of facilitating insertion.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
