Description

Return device for fuse

The invention relates to a device for returning a fuse, and in particular to a technology related to the field of plug-in fuses, the main technical feature of which is to provide a user with the ability to replace at a minimum cost and in the most efficient manner. It is an invention with excellent practicality.

Fuses, also known as fuses and fuses, are mainly used as a disposable component that is connected to a circuit to protect the circuit. Generally, fuses commonly used in the market usually use low-melting lead-tin alloy, zinc, copper, and silver. Made of filament or sheet material. When the current on the circuit is too large, the metal wire or the piece is melted at a high temperature, causing an open circuit to interrupt the current to protect the circuit from damage. Generally, when the electrical equipment is turned on, there will always be a certain inrush current, which is higher than the normal working current. If the fuse is blown immediately, it will cause troubles. In order to meet the needs of the circuit characteristics, the fuse can be divided into several types according to the fuse rate. The type of fusing rate is usually indicated by an English letter code: common T (Time-lag) stands for slow-melting type, F (Fast) stands for fast-melting type, and M (Medium time-lag) stands for medium speed. In addition, it has a wire fuse, a chip (die) fuse, a glass tubular fuse, a ceramic tube, a plastic sheet with a metal chip pin, a surface follower element (SMD) type, a cylindrical plug type, etc. Different types of fuses are used differently.

According to the types of fuses mentioned above, the present invention further explores plastics Sheet metal strip pin fuses. The most common type of fuses are car fuses. Please refer to the Republic of China Patent Bulletin No. 543916 "Fuse-Illuminated Warning Fuse". The structure includes a cover plate: one at each end. The perforation is such that the end of the conductive insert can be penetrated; the cover is attached to the upper surface of the housing after the conductive insert and the light-emitting element are assembled in the housing. A casing: an accommodating chamber is disposed inside the center of the upper end, and a light-emitting element, a resistor, or the like can be placed therein. A conductive insert has a sloping plate which is outwardly inclined on the left and right sides of the upper end; each end of the inclined plate is provided with one end leg, and after the combination is completed, the end leg penetrates into the two perforations of the cover plate. A light-emitting element: the two ends of the two sides are respectively soldered on two slanting plates of the conductive inserts on both sides of the fuse, and will illuminate when the fuse is blown to indicate that the fuse has been burnt.

The fuses mentioned above are the most common on the market today. Although the user can know that the fuse has been blown through the illumination of the light-emitting element, it must be replaced to ensure the safety of the vehicle. However, the fuse has several defects, one of which is not the price. Fiji, and each time the fuse is blown, the whole piece must be eliminated and replaced. In the long-term cost, the user will not be burdened by the cost. The second is that the light-emitting element is not damaged and is discarded due to the fuse being blown. In addition, problems such as environmental pollution may occur. According to the above-mentioned shortcomings of the "fuse-emitting warning fuse", the relevant industry must carefully consider how to improve the fuse for such a vehicle. Meet the needs of the public.

In view of the above situation, the inventors invested a lot of time to study relevant knowledge, and compared various advantages and disadvantages, research and development of related products, and many experiments and tests, and finally introduced a "replacement device for fuses" 』Improve the above missing to meet the needs of the public.

The main technical feature of the present invention is to provide a user capable of targeting The damage can be replaced, thereby achieving the purpose and efficacy of reducing costs; the secondary purpose is to reduce the replacement of the entire group and affect the environment, which improves the lack of the aforementioned technologies, and the missing system In order to eliminate the cost of the entire group, there will be a huge expenditure. In addition, the entire group will also cause waste of parts that have not been damaged, and environmental pollution.

In order to achieve the above-mentioned purpose and effect, the present invention is a device for replacing a fuse, which is mounted on a casing, the casing is respectively provided with a perforation at opposite ends, and a conductive insert is arranged in the casing. One end of the conductive insert passes through the perforation at either end of the housing, and is characterized in that: a lamp cover has a shell groove recessed at one end thereof, and the lamp cover is provided with a conductive insert through the shell groove sleeve. The light-emitting element is mounted on the lamp cover, and the light-emitting element has a light source body and a pin portion, and the light source body and the light-emitting element are respectively connected to the lamp cover. The lamp cover is electrically connected to the housing, and the lamp cover is assembled to the housing and electrically connected to the end portion of the conductive insert that does not pass through the housing; wherein the lamp cover can be detached from the housing, In the cover setting, when only the conductive insert is blown, the user can replace only the housing, thereby achieving the purpose and effect of reducing excessive cost and avoiding waste of the light-emitting element.

According to the foregoing description, the further technical feature is that the conductive insert further comprises a second leg and a fuse, wherein the two legs are spaced apart, and the two ends of the fuse are respectively connected to the two legs.

According to the foregoing description, the further technical feature is that the housing is further provided with a receiving chamber for connecting the perforations, and the housing wall surface is respectively provided with a bump corresponding to the two legs, and each of the legs is respectively A positioning hole is defined in the corresponding protrusion, and each of the protrusions is inserted into the corresponding positioning hole and fixes the assembly of each foot in the housing.

According to the foregoing description, the further technical feature of the present invention is that the pin portion of the light-emitting element further includes two pins, and each pin is connected to one end of the light source body at one end to be exposed to the lamp cover, and the lamp cover is The conductive insert is electrically connected to the housing and is inserted into the housing at the exposed end of the two pins.

According to the foregoing description, the present invention is further characterized in that the outer side of the lamp cover is provided with at least one anti-slip row.

In combination with the above technical features of the present invention, the advantages are as follows: 1. The user can use the housing and the lamp cover as a detachable arrangement, and only need to replace the housing after the fuse is blown, It must be discarded along with the lamp cover, thereby reducing excessive costs. Second, the housing and the lamp cover are provided with a detachable arrangement to provide convenience for the user. After the user confirms the discarded components, it is only necessary to replace the component group that has not been damaged yet with the discarded new component. Continue to operate, thereby avoiding excessive waste and reducing environmental pollution. Third, through the cooperation of the bump and the positioning hole of the two-legged foot, the chance of the second leg being separated from the casing is reduced, thereby allowing the light-emitting element to be electrically connected to the two-legged foot. Therefore, the present invention can be said to be a practical and progressive invention, which is quite worthy of promotion by the industry and is publicized to the public.
