Description

Technical Field

[0001] The utility model relates to the field of electronic technology, in particular to an ultra-thin low-voltage direct current buckle plate. Background Art

[0002] In a DC circuit, the active connection of two or more lines, including the use of an external DC power supply to supply power to electrical appliances, almost all adopts the traditional direct plug-in male and female plug-in method. This method has two disadvantages: first, the docking direction can only be a unique opposite-direction straight plug-in, which is greatly restricted in the docking direction and affects the convenience of use. For example, the charging of commonly used low-voltage DC appliances such as mobile phones and computers can only be directly plugged in one direction; second, the purpose of the direct plug-in male and female plug docking is only to complete the straight-line docking. Therefore, the size of the docking connector diameter is not taken seriously. This results in some specific occasions, such as various close-fitting DC physiotherapy appliances for the human body, the connector will be too protruding, which is neither beautiful nor applicable.

[0003] In recent years, many magnetic docking methods have appeared in technical fields such as mobile phone charging, such as the "USB data cable magnetic head" with patent application number 201921535098.5, and the "A magnetic head with better contact effect" with patent application number 201821879233.3. This magnetic connection method facilitates the connection and disconnection during docking, and is more convenient to use than the traditional plug-in type. However, the magnetic type is still a linear docking method, and must be connected in a single linear direction during docking. In addition, the thicker plug diameter also increases the thickness when used on a flat surface.

[0004] With the aging of the world's population, the health industry is developing rapidly. Various protective gear and medical products using low-voltage DC power supplies below 36 volts are emerging one after another, such as various graphene neck protectors, waist protectors, electric blankets, etc. These products are mainly used close to the human body. Therefore, whether it is the protective gear body or related accessories, they should pursue ultra-thinness in the plane direction. If a traditional direct-plug power plug is used, either the plug must be left outside, which is not beautiful, or the plug is set on the protective gear body, resulting in a convex face, which is inconvenient to use. It is particularly important to improve the drawbacks of power supply connectors and accessories of products such as DC protective gear as soon as possible. Summary of the invention

[0005] Based on the technical problems existing in the background technology, the utility model proposes an ultra-thin low-voltage DC buckle sheet, the purpose of which is to manufacture a low-voltage DC conversion method through thin sheet bonding to adapt to the convenience and ultra-thinness of protective gear and other products when using the power interface.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an ultra-thin low-voltage DC buckle plate, comprising a male buckle plate and a female buckle plate, wherein the male buckle plate and the female buckle plate are both composed of an insulating base plate and an exposed metal sheet attached to the base plate, and the metal sheet of the male buckle plate and the metal sheet of the female buckle plate can be electrically connected when the male buckle plate and the female buckle plate are relatively fitted.

[0007] Preferably, the metal sheet of the male buckle piece is two mutually insulated concentric rings, and the metal sheet of the female buckle piece is two mutually insulated concentric rings with the same diameter as the two concentric rings of the male buckle piece. The purpose is to ensure that when the male buckle piece and the female buckle piece are fitted, the respective rings of the same diameter can be in corresponding electrical contact.

[0008] Preferably, the insulating base sheets of the male and female buckle pieces contain magnetic materials to enhance the tightness of the electrical contact of the corresponding metal sheets when the male and female buckle pieces are fitted together.

[0009] Preferably, the axis of the insulating base piece of the male buckle piece is provided with a protruding tongue, and the axis of the insulating base piece of the female buckle piece is provided with a recessed slot, and the tongue and the slot can be tightly engaged when the male buckle piece and the female buckle piece are relatively fitted.

[0010] Preferably, the male connector and the female connector are suitable for a DC voltage not exceeding 36 volts.

[0011] When the utility model is used, the male head of the buckle piece and the female head of the buckle piece are relatively fitted in the direction of the metal sheet, and the corresponding metal sheets on the male head of the buckle piece and the female head of the buckle piece are electrically and tightly connected to connect the circuits corresponding to the metal sheets.

[0012] Compared with traditional technologies, the beneficial effects of the utility model are: an ultra-thin low-voltage DC connector, which uses a thin sheet bonding method to perform active docking of low-voltage DC lines, overcoming the disadvantages of traditional straight-plug connectors with limited connection direction and excessively thick plugs. When used in the fields of physical therapy protective gear, it can achieve 360-degree docking without dead ends, and make the docking thickness ultra-thin, making it easier to combine and disconnect during use.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0021] Reference Figure 1-Figure 4 An ultra-thin low-voltage DC connector includes a male connector and a female connector. Both the male connector and the female connector are composed of an insulating base sheet 3 and an exposed negative metal ring 1 and a positive metal ring 2 attached to the insulating base sheet 3. The negative metal ring 1 and the positive metal ring 2 are concentric rings, and the two rings are insulated from each other.

[0022] The insulating base piece 3 of the male buckle piece and the female buckle piece includes a magnetic attraction material 4 .

[0023] A protruding latch tongue 5 is provided at the axial center position of the insulating base piece 3 of the male buckle piece, and a recessed latch groove 6 is provided at the axial center position of the insulating base piece 3 of the female buckle piece. The latch tongue 5 and the latch groove 6 can be tightly fastened when the male buckle piece and the female buckle piece are relatively fitted.

[0024] When in use, press the tongue 5 on the male head of the buckle piece into the slot 6 on the female head of the buckle piece. Through the snapping action of the tongue 5 and the slot 6, and the magnetic attraction between the magnetic attraction materials 4 arranged on the male and female heads of the buckle piece, it can be ensured that the negative metal ring 1 and the positive metal ring 2 on the male and female heads of the buckle piece are correspondingly and tightly electrically connected to each other. Embodiment 2:

[0025] Reference Figure 5-Figure 6An ultra-thin low-voltage DC buckle connector includes a male buckle connector and a female buckle connector. Both the male buckle connector and the female buckle connector are composed of a disc-shaped insulating base plate 3 and an exposed negative metal ring 1 and a positive metal ring 2 attached to the insulating base plate 3. The disc-shaped insulating base plate 3, the negative metal ring 1, and the positive metal ring 2 are concentric, and the two metal rings are insulated from each other. The edge of the insulating base plate 3 of the male buckle connector or the female buckle connector is provided with a raised outer ring 7 to ensure the accuracy of the male buckle connector and the female buckle connector when they are connected.

[0026] Embodiment 2 merely eliminates the engagement structure of the tongue 5 and the slot 6 in Embodiment 1, and only ensures that the negative metal ring 1 and the positive metal ring 2 on the male and female ends of the buckle piece are electrically connected to each other closely through the magnetic attraction between the magnetic attraction materials 4 provided on the male and female ends of the buckle piece. This simple structure can be used under human safety voltage, especially in close-fitting protective gear products with a DC voltage below 12 volts, when ultra-thin thickness of the connection position is sought.

[0027] In the utility model, since the circular base piece and the positive and negative metal rings are all concentric, when the male and female buckle pieces are fitted together, electrical connection at any angle in the plane can be achieved.

[0028] The utility model is suitable for external DC power supply connection under various DC low voltage conditions, such as various physical therapy electrical appliances used outside the human body. It is particularly suitable for many occasions that require multiple DC power supply connection angles or require a flat ultra-thin thickness at the socket position, such as charging of mobile phones, tablet computers, and laptop computers.

[0029] The design of the utility model emphasizes that it is suitable for low-voltage DC electrical appliances mainly because its structure is set to make the corresponding metal sheets contact each other. This surface contact will produce air resistance. When used under high voltage and high power conditions, the increase in air resistance will cause heating of the contact surface, causing unsafe factors.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the specification should not be regarded as limiting the claims involved.
