Each of the body and the cover part is provided with a loop part, and a connection connecting the loop parts to each other. A case with a ring; A battery cell built in the case and charged with electricity from the outside; A circuit unit embedded in the case and including a function of preventing overcharging and full discharge of the battery cell; A plug mounted to the case and capable of being coupled to and separated from an input / output connector of the mobile phone; A connector which is mounted to the case and coupled to an external electricity supply device to supply electricity to the battery cell, wherein the case further includes a light emitting diode and a switch for operating the light emitting diode. The small battery device of a mobile phone characterized in that the light-emitting diode is turned on and off by on / off.

The Korean Patent Application No. 1020050044883 discloses that the materials provided with the case and the cover are provided by plastic injection molding, and commercially available according to the invention. The same is true of the product in question.

The product, which is carried out in the contents of Korean Patent Application No. 1020050044883, has a problem of terminal corrosion or moisture penetration due to lack of waterproof function of one connector part without a cover, and is caused by loss of adhesion due to frequent opening and closing of the cover. That is, there is a problem that the cover is always open, and there is a problem that is easily damaged by the impact, and also, it is not possible to recognize whether it is time to charge even if the charged voltage is discharged below a certain amount of energy. There is also. In addition, the manufacturing process of the case consists of the upper and lower cases of the cover, there is also a problem that the productivity is hindered because the number of components.

It is obvious that a product is sold a lot when its merchandise is high and its income is increased. However, to look at the conventional products, the frequency of when the auxiliary power supply also feels the necessity, that is, the frequency of use is low, and the LED lighting that acts as a flashlight also has a low frequency of use. This can be said to fall.

In addition, the technique of the above-described invention, after all, the technique of the known technique "battery provided with a lithium ion battery and the like and the electric circuit device for controlling the charge and discharge of the rechargeable battery" and the known configuration of the configuration of the case "cover is provided (Technology applied for utility model described below), and "light emitting LED for a flashlight function" was added and comprised. In other words, it can be said to be a practical level of invention configured for the purpose of supplying the auxiliary power of the mobile phone and the use of an emergency flashlight, which can be carried as an accessory to the mobile phone.

In addition, the "Korean Patent Application No. 1020050044883" is used for emergency purposes, but if the battery is discharged in the mobile phone, the auxiliary power supply of the invention is also discharged, it is not easy to cope with the emergency situation There are also problems that arise.

To look at the prior art other than the above, it has been filed earlier than the "Korean Patent Application No. 1020050044883" described above, but the somewhat more advanced and convenient, the auxiliary power generating means should be always provided with a general AAA type plurality of batteries Falling and lacking in weight due to inconvenient portability, "Korean Utility Model Application No. 2020010033563" and "Korean Utility Model Application No. 2020010023871", etc., are marketed as relatively low price products, but connected to the case and cover Since the contents of the providing technology constituting the outer shape of the ring and the like and the construction technology having the input / output terminals are similar, a separate description will be omitted.

The technical field of the present invention and the prior art have been described based on the contents and commercially available products, and the purpose of the present invention to improve the above-mentioned conventional problems.

The present invention is to provide a more improved and advanced technical configuration in consideration of the conventional problems and reality.

The present invention is provided as an auxiliary power supply device when a main battery discharge of a portable terminal suddenly occurred while going out, and in addition to its basic role as an auxiliary power supply device of the terminal, it is possible to focus attention at meetings, presentations, presentations, and the like. A focus light divergence function, which is a conventional laser pointer function used to indicate a remote location, is provided, and is provided so that it can be used while being carried on a terminal. The focus light divergence function which is charged by a charger or a battery is used. An object of the present invention is to provide a power supply device for a portable terminal.

To explain more,

The means for receiving charging energy are "chargers operated on commercial ac power supplied by the terminal purchase" or "batteries suitable for a certain size and discharge voltage on the market that are relatively easy to purchase" to accommodate both energy sources. The present invention is designed to provide a power supply for a portable terminal, which has a general LED and an optical condenser lens and has a focus light divergence effect.

In the present invention, the technical problems to improve and advance compared to the prior art are as follows.

Firstly, in order to increase the consumption desire to have a product, that is, the purchase desire from consumers, the use of a flashlight (LED flash) function which is low in frequency of use and the need for consumption is eliminated, and a meeting or a report presentation and a presentation or a play or a presentation presentation are performed. In practice, the subject focuses the LED and the LED light into a focus to provide a divergence function of a focus light, a function called a conventional laser pointer, which is used by a subject to irradiate light to an instruction place for the purpose of focusing the subject's eyes. Construct an optical lens to diverge.

Second, as a problem to improve the disadvantages of the outer appearance of the product compared to the prior art, by using a silicone rubber divided configuration of the cover, upper case, lower case provided with a resin material, harmless to the human body, falling and mobile vibration Shock is cushioned, heat insulation is increased so that external heat is not easily transferred, and wear resistance can be increased to improve looseness due to friction generated when the cover is opened and closed, and the gap between switch parts can be eliminated. It prevents penetration, and also installs a cover on both sides of the connector to increase airtightness and water resistance, thereby preventing the explosion of lithium ion batteries and damaging electric circuit devices. Produced by manufacturing the cover and case integrally or by insert molding to enable external appearance Reduce costs.

By solving the above second problem, the conventional case is provided with a large amount of friction electricity aka static electricity generated by being provided with a plastic resin material, flows into the semiconductor element of the electrical circuit device is also incidentally solved the problem that the circuit function is damaged.
