[0035] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application. As used in the specification and the appended claims of the application, the singular forms "a," "an" and "the" are intended to include both singular and plural forms, unless the context clearly indicates otherwise. It will be further understood that the terms "and / or," as used in the specification and in the claims, are used to mean any one of the items listed or all possible combinations of the items.

[0036] Hereinafter, the terms "first" and "second" are used only for the purpose of description and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0037] The technical solutions of the embodiments of the present application are described in detail below in conjunction with the drawings.

[0038] Reference is made to Figure 1 and Figure 2The portable power supply multi-channel protection patch fuse holder disclosed in this application includes: a base 10, a first terminal 20, a second terminal 30, a pad 40, and a copper foil 50. The first terminal 20 and the second terminal 30 are disposed opposite each other on both sides of the base 10. The pad 40 is located between the first terminal 20 and the second terminal 30. The copper foil 50 is disposed at both ends of the pad 40 and is respectively connected to the first terminal 20 and the second terminal 30.

[0039] The pad 40 is used to electrically connect the fuse to the copper foil 50 at both ends. The copper foil is disposed in the base substrate and acts as a conductor of the base. The fuse is disposed on the pad 40. Multiple first terminals 20, pad 40, copper foil 50, fuse, and second terminals 30 are electrically connected to form an electrically conductive fuse circuit. Figure 2 As shown, 10 parallel fuse lines are provided on the base 10, which can provide electrical connection for 10 circuits.

[0040] Specifically, the first terminal 20 and the second terminal 30 have the same structure, allowing external wires to be inserted into the internal space of the terminal. The wires are then secured by screws, and the circuit is completed at both ends of the wires using copper foil 50, solder pads 40, and a fuse. The fuse automatically melts in case of circuit overload, thus breaking the circuit and ensuring electrical safety. It should be noted that the length, width, number of circuits, and the width and thickness of the copper foil of the base 10 can be designed according to the current and its range used by the equipment. The current that the base 10 can withstand is related to the width and thickness of the copper foil 50.

[0041] See Figure 2 The base 10 has a width of ±0.1mm and a length of 135±0.1mm, with 10 channels. In each channel, the copper foil 50 has a thickness of 7um and a width of 10mm, for use in circuits with a current of 12.5~20A. Of course, the copper foil 50 can also have a thickness of 35um and a width of 2mm, for use in circuits with a current of 4A.

[0042] In each circuit, the copper foil 50 has the same thickness and width to withstand the same current range, supporting multiple identical circuits connected to the base. Of course, when one fuse blows, the operator can restore circuit continuity without replacing the fuse by disconnecting the wire connecting the first terminal 20 and the second terminal 30 in the original circuit and changing the connection between the first terminal 20 and the second terminal 30 in another circuit. This allows for easy replacement of fuses in different circuits, simplifying the installation and maintenance process.

[0043] In the embodiment, in order to facilitate viewing the current range applied to the circuit, the base 10 is further provided with a first mark 70 of the current range applied, such as 1A-5A, so that the operator can intuitively know the current size that the circuit on the base 10 can bear, thereby improving the use safety.

[0044] Referring to Figure 3 In another embodiment, the thickness and width of the copper foil 50 in each circuit are not the same, so that the multi-circuit can bear different sizes of current, so that the same base 10 is applied to circuits of different power sizes. Of course, in this embodiment, a plurality of circuits with the same thickness and width of the copper foil 50 can be provided, so that when a circuit fails, a circuit applied to the same current range can also be replaced.

[0045] In this description, the product (fuse base 10) corresponding to the embodiment is applied to 2410, 4012, 1032, 1245, 4818, 5x20mm, 6x32mm type fuses.

[0046] Referring to Figure 3 The second mark 80 of the current range applied to each circuit is provided on the side of the second terminal 30, such as 4A, 5A, 10A, 15A, 20A, 25A, 50A, 70A, 80A, 100A, so that the operator can intuitively know the current size that each circuit on the base 10 can bear, so as to facilitate connecting the corresponding circuit in the corresponding circuit, thereby improving the use safety.

[0047] Further, the solder pad 40 is used to realize the electrical connection of the copper foil 50 at both ends. In the embodiment, the fuse is soldered on the solder pad 40 by soldering, so as to be connected together with the copper foil 50 at both ends to realize the electrical conduction of the circuit.

[0048] Referring to Figure 2 In another embodiment, the base 10 is further provided with a metal seat 90 fixed on the solder pad 40, connected to the copper foil 50 at both ends, and the fuse is pressed into the metal seat 90 by external force to be electrically conducted with the copper foil 50 at both ends through the metal seat 90. Here, the structure of the metal seat 90 is not limited.

[0049] Referring to Figure 1 There is an indicator light 60 on the side of each first terminal 20, and the indicator light 60 is a light-emitting diode. Of course, it can also be connected to the side of the second terminal 30, because the structures are the same, and here they can not be distinguished.

[0050] Wherein, the circuit in the normal on state, indicating light 60 presents bright light state; circuit failure such as fuse blown, then the line circuit, indicating light 60 presents off state, so that the line circuit is on, can directly show the circuit fault such as fuse working state, in order to facilitate the operator to quickly determine whether the circuit is working properly, and in the event of a failure to maintain timely.

[0051] In summary, the portable power supply multi-path protection patch fuse holder disclosed by the embodiment of the application, through the relative arrangement of the first wiring terminal 20 and the second wiring terminal 30 and the position arrangement of the solder pad 40, the stability and reliability between the lines are ensured. At the same time, the first wiring terminal 20, the second wiring terminal 30, the solder pad 40 and the copper foil 50 are arranged as multiple, forming multiple conductive lines. After the fuse in one of the lines is blown, only the fuse in the line needs to be replaced, and the line can be used again, simplifying the installation and maintenance process. By increasing the indicating light 60, the circuit conduction state can be directly displayed, which is convenient for the operator to quickly determine whether the circuit is working properly or has failed. By arranging the thickness and width of the copper foil in each line to be different, the multi-path line can withstand different sizes of current, so that the same base 10 can be suitable for circuits of different power sizes.

[0052] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
