Description

Technical Field

[0001] This invention relates to the field of charger technology, and more particularly to a "T"-type multi-connector charger. Background Technology

[0002] A charger is essentially a device consisting of a stable power supply (primarily a regulated power supply, providing a stable operating voltage and sufficient current) plus necessary control circuits for constant current, voltage limiting, and time limiting. Nowadays, with the rapid development of electronic products, people have all sorts of chargers at home. Many charging devices have different charging interfaces, which is very frustrating. Every time you tidy up chargers, the length of the data cables often causes them to become tangled, which is extremely annoying and can also cause unavoidable damage to the charger. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a technical solution: a "T"-shaped multi-connector charger, comprising a "T"-shaped housing, a charging interface, circuit board A, a spring, circuit board B, a plug, a push rod, and a fixing plate, characterized in that: the "T"-shaped housing has an internally hollow structure and a pressing hole is provided at the top; the push rod passes through the pressing hole of the "T"-shaped housing; one end of the spring is installed at the bottom of the "T"-shaped housing, and the other end of the spring is connected to circuit board A; circuit board B is fixed at the inner edge of the "T"-shaped housing, and a plug is connected to circuit board B; the fixing plate is located on the same side of the outer surface of the "T"-shaped housing as the charging interface.

[0004] Preferably, the push rod is a hollow cylindrical structure with four sloping protrusions at the bottom. The lower edge of the push rod is serrated, and the upper half of the protrusions is arc-shaped. The push rod is installed inside the fixed sleeve with clearance fit. The fixed sleeve is a hollow cylindrical structure with a groove and sloping at the bottom. One end of the fixed sleeve is fixed to the top of the "T"-shaped housing. The upper half of the rotating column is smaller than the lower half. The rotating column is a cylindrical structure with four sloping high protrusions on the outer edge of the lower half. The upper half of the rotating column is confined inside the push rod, and the lower part of the rotating column is fixed at the center of the circuit board A.

[0005] Preferably, a contact ring is arranged at the center of the circuit board A, and the contact ball is connected to the circuit board B through an iron rod, with the spherical surface of the contact ball contacting the contact ring.

[0006] Preferably, the circuit board A has a square structure with a charging interface of a certain type arranged on each of its four sides. A rubber block is arranged at the right angle position. The height of the rubber block is the same as the height of the charging interface and the rubber block is elastic. The charging interface is connected to the circuit board A.

[0007] Preferably, both the contact ball and the contact ring are made of conductive materials.

[0008] The beneficial effects of the above solution are: 1. By setting an inverted "T" shaped shell, the present invention allows the charger to be conveniently placed on a table to charge electrical appliances. At the same time, the inverted "T" shaped structure allows electrical appliances to be placed upright, making it convenient for users to observe the charging status of electronic products with display functions.

[0009] 2. This invention features a press-and-rotate mechanism. By pressing the push rod on the top of the housing, the internal rotating mechanism rotates, and the rotating column drives the circuit board A to rotate, thereby switching the charging interface to meet the charging needs of different electrical devices and avoiding the inconvenience caused by numerous charging cables.

[0010] 3. By setting a rubber block in circuit board A, when the charger is not in use, pressing the push rod and rotating circuit board A will rotate the rubber block to the charging interface outlet for sealing, thereby providing a dustproof effect and improving the service life of the device.

[0011] 4. This invention features a press-type rotary replacement charging interface. By engaging and disengaging the contact ball and contact ring, the charging interface can be safely replaced without unplugging the plug. Attached Figure Description

[0020] The present invention will be further described clearly and completely below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0021] A T-shaped multi-connector charger includes a T-shaped housing 1, a charging interface 2, a circuit board A3, a spring 4, a circuit board B7, a plug 8, a push rod 11, and a fixing plate 14. The T-shaped housing 1 is hollow internally and has a pressing hole at the top. The push rod 11 passes through the pressing hole in the T-shaped housing 1. One end of the spring 4 is installed at the bottom of the T-shaped housing 1, and the other end of the spring 4 is connected to the circuit board A3. The circuit board B7 is fixed at the inner edge of the T-shaped housing 1 and is connected to the plug 8. The fixing plate 14 is located on the outer surface of the T-shaped housing 1 on the same side as the charging interface 2.

[0022] Specifically, the push rod 11 is a hollow cylindrical structure with four sloping protrusions 111 at the bottom. The lower edge of the push rod 11 is serrated 112. The upper part of the protrusions 111 is arc-shaped. The push rod 11 is installed inside the fixed sleeve 10 with clearance fit. The fixed sleeve 10 is a hollow cylindrical structure with a groove 102 and a slope 101 at the bottom. One end of the fixed sleeve 10 is fixed to the top of the "T"-shaped housing 1. The upper half of the rotating column 9 is smaller than the lower half. The rotating column 9 is a cylindrical structure with four sloping high protrusions 91 on the outer edge of the lower half. The upper half of the rotating column 9 is confined within the push rod 11. The lower part of the rotating column 9 is fixed at the center of the circuit board A3.

[0023] Specifically, a contact ring 6 is arranged at the center of the circuit board A3, and the contact ball 5 is connected to the circuit board B7 through an iron rod. The spherical surface of the contact ball 5 contacts the contact ring 6.

[0024] Specifically, the circuit board A3 has a square structure with a type of charging interface 2 arranged on each of its four sides. A rubber block 31 is arranged at the right angle position. The height of the rubber block 31 is the same as the height of the charging interface 2 and the rubber block 31 is elastic. The charging interface 2 is connected to the circuit board A3.

[0025] Specifically, both the contact ball 5 and the contact ring 6 are made of conductive materials.

[0026] Working Principle: A "T"-shaped multi-connector charger includes a "T"-shaped housing 1, a charging interface 2, a circuit board A3, a spring 4, a contact ball 5, a contact ring 6, a circuit board B7, a plug 8, a rotating column 9, a fixing rod 10, a push rod 11, a fixing rod 12, and a fixing plate 14. Its characteristic is that during operation, the plug 8 is inserted to connect the charging device to the charging interface 2 for charging. The fixing plate 14 can fix the charging device to prevent it from tilting to the left or right. When charging a device with a different interface, the push rod 11 is pressed. The rod moves vertically downward within the fixed sleeve 10, pushing the rotating column 9 through the protrusion 111 at the lower part of the push rod 11. Since the lower half of the protrusion 111 of the push rod 11 is conical, and the rotating column 9 also has a high protrusion 91 and a slope, the rotating column 9 will be pushed out of the groove of the fixed sleeve 10 by the pushing force of the push rod 11. Under the action of the slope, the rotating column 9 will slide into the slope of the fixed sleeve 10. At this time, the charging interface 2 has not yet popped out. Pressing the push rod 11 again will cause the high protrusion slope of the rotating column 9 to rotate and slide into the groove of the fixed sleeve 10. Because the rotating column 9 is fixed to the circuit board A3, it drives the circuit board A3 to rotate, completing the replacement of the charging interface. When replacing the connector, the push rod 11 presses down, compressing the lower spring 4 and separating the contact ball 5 from the contact ring 6, thus de-energizing the device. This provides power-off protection during the replacement of the charging interface 2. When the replacement of the charging interface 2 is complete, the spring 4 lifts the circuit board A to resume normal operation. When the charger is not needed, simply press the push rod 11, causing the high protrusion of the rotating column 9 to be locked in the inclined surface of the fixing sleeve. At this time, the contact ball 5 and the contact ring 6 are separated, the charger is de-energized, and the charging interface 2 is retracted into the "T"-shaped housing 1 to protect the charging interface and the charger. The embodiments of the present invention disclosed are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
