1. Field of the Invention
The present invention generally relates to a fuse seat, in particular, to a fuse seat having a light-emitting module of hidden type.
2. Description of Prior Art
Comprehensively, a general fuse is used in an electric product. When current passing through the electric product exceeds a load endurable by the fuse, the fuse will be fused and broken off to prevent circuit board or electronic component in the electric product from damage. Therefore, any electric product, for example, used in power switch or vehicle, is endowed with a protection function, when equipped with this kind of protective device.
According to prior arts, a fuse device used in vehicle mainly includes a fuse seat, two electricity-conducting pieces and a fuse. The fuse seat is arranged an accommodating space and two fixing troughs connected to the accommodating space. Two electricity-conducting pieces are fixed in two fixing troughs respectively. Two sides of each electricity-conducting piece are wound into an inserting trough, and the fuse is inserted into two inserting troughs respectively. The fuse includes a shell and a light-emitting module arranged and embedded fixedly in the shell.
Under normal using condition, when current passes through the fuse, the light-emitting module won't emit light. However, when the fuse is broken off due to overload, current will pass through the light-emitting module instead, making an emission of light for indicating that this fuse has been burned down.
Nonetheless, this kind of fuse still has many drawbacks during practical use. For example, since the light-emitting module is embedded and accommodated fixedly in the shell of the fuse seat, the light-emitting module has to be discarded together with the burn down fuse that is already useless. In terms of product cost, discarding undamaged light-emitting module is a waste.
Accordingly, aiming to solve aforementioned shortcomings, after a substantially devoted study, in cooperation with the application of relatively academic principles, the inventor has at last proposed the present invention that is designed reasonably to possess the capability to improve the prior arts significantly.
The invention is mainly to provide a fuse seat having a light-emitting module of hidden type. Through hiding the light-emitting module in an accommodating space in an insulating body instead in the fuse itself, when the fuse is burned down, the light-emitting module is unnecessarily thrown away with the useless fuse, thus that an effect of cost saving is achieved.
Therefore, the invention is to provide a fuse seat having a light-emitting module of hidden type and a fuse plugged therein conductively. The fuse seat includes an insulating body, two electricity-conducting pieces and a light-emitting module. The insulating body is arranged an accommodating space, in which two electricity-conducting pieces are respectively fixed. The fuse is plugged into the accommodating space and connected conductively to the electricity-conducting pieces. The light-emitting module is hidden in the insulating body and is connected electrically to the electricity-conducting pieces respectively.
The features of the invention believed to be novel are set forth with particularity in the appended claims. The invention itself, however, may be best understood by reference to the following detailed description of the invention, which describes a number of exemplary embodiments of the invention, taken in conjunction with the accompanying drawings, in which:
In cooperation with attached drawings, the technical contents and detailed description of the present invention are described thereinafter according to a number of preferable embodiments, being not used to limit its executing scope. Any equivalent variation and modification made according to appended claims is all covered by the claims claimed by the present invention.
Please refer to
The insulating body 10 is arranged an accommodating space and two fixing troughs 11 communicating the accommodating space 11. The accommodating space 11 is arranged on a top face of the insulating body 10 and is shown as a rectangular opening. Two fixing troughs 12 are respectively arranged in the insulating body 10, located under the accommodating space 11 and shown respectively as a substantial elliptical open trough.
Two electricity-conducting pieces 20 are arranged and fixed in two fixing troughs 12 respectively. The fuse 50 plugged in the accommodating space 11 is connected conductively to two electricity-conducting pieces 20. The electricity-conducting piece 20 includes an abutting connecting part 21 and two elastically clipping holding parts 22 extended from two sides of the abutting connecting part 21 and wound inward. An inserting trough 23 is formed between the elastically clipping holding part 22 and the abutting connecting part 21.
Two electric wires 30 are respectively connected to two electricity-conducting pieces 20 conductively and are extended out of the insulating body 10.
The light-emitting module 40 includes two conductively connecting legs 41 respectively connected to two electricity-conducting pieces 40 electrically, a circuit board 42 connected to two electricity-conducting pieces 20 electrically, an LED lamp 43 connected to the circuit board 42 electrically and a resistance 44 connected to the circuit board 42 electrically. The resistance 44 has a high resistance value, or the light-emitting module 40 is an LED having a high resistance value, hidden in the accommodating space and electrically connected to two electricity-conducting pieces 20. In this case, two conductively connecting legs 41 of the light-emitting module 40 are respectively plugged in two inserting troughs 23. When the light-emitting module 40 is damaged, two inserting troughs 23 are pulled out to replace another light-emitting module.
The fuse 50 includes a shell 51 and two metallic inserting pieces 52 accommodated in the shell 51. The shell 51 is made of material with transparence or superior transparence and is arranged a positioning trough 53 at a central position thereof. The positioning trough 53 is formed between two metallic inserting pieces 52 and is provided for the light-emitting module 40 to be positioned. Two metallic inserting pieces 52 are partially exposed out of the shell 51 and can be respectively inserted in two inserting troughs 23.
During assembling process of the invention, first, two conductively connecting legs 41 of the light-emitting module 40 are respectively inserted and elastically clipped and abutted in two inserting troughs 23, each which is formed from two electricity-conducting pieces 20 in the insulating body 10, in the meantime, making the light-emitting module 40 fixed between two electricity-conducting pieces 20 and electrically connected thereto; finally, the fuse 50 is plugged into two inserting troughs 23 through two metallic inserting pieces 52 respectively, while the elastically clipping holding part 22 and the abutting connecting part 21 clip and abut the metallic inserting piece 52; thereby, the fuse 50 is fixed to the insulating body 10, while the light-emitting module 40 is positioned in the positioning trough 53.
When using the invention, first, two electric wires 30 are respectively connected to a power source, current passing through the fuse 50, instead of passing through the LED lamp 43 of the light-emitting module 40, so there is no light emitted from the LED lamp 43. When the fuse 50 is melted and broken off due to an occurrence of overload, current will pass through the LED lamp 43 instead and make a light emission. The light irradiates out of the shell 51 of the fuse 50 to indicate that the fuse 50 has already been burned down and is needed to be replaced. As soon as the fuse 50 is burn down, the fuse 50 is with no use any more. However, when the useless fuse 50 is discarded, the undamaged light-emitting module doesn't have to be thrown away together, thus that an effect of cost saving is achieved.
