Abstract

The utility model relates to a fuse base with a display of an auto audio system in the auto audio electric fitting field. Because the fuse base in use only has the break function and without a light display or the function of displaying the digital voltage value, the fuse base with a display is designed. The utility model is characterized in that a circuit board is fixed in the cavity of the base; the components including a display block, a display light and a red indictor are arranged on the circuit; four-way wires are connected with small copper blocks of each channel through imbedding channels; a copper plate is embedded in the base; a negative line of the circuit board is connected with the ground through the copper plate and the screw hole of the bottom board and reaches the automobile chassis; the power wire is connected with the big copper block and the small block and is fixed by a screw arranged above, then is arranged in the fuse tube; the utility model is realized after the shell is covered. When the fuse tube is fused, the display light is off; the red indictor is off when the voltage is lower than the rated value. The utility model which can remind the user to solve the relative problem in time has simple structure, simple application, convenient operation and certain application value.

Description

The automobile audio band shows fuse holder

Affiliated technical field

The utility model relates to automobile audio electrical accessorie field, is that a kind of automobile audio band shows fuse holder, model XA-1371.

Background technology

At present, the automobile audio fuse holder only has cut-out function, and operating voltage surpasses rated voltage promptly automatically with blown fuse, and does not have the function of lamp demonstration and digital display voltage value.Under the dim and remote situation of weather, can not see obviously whether fuse fuses, more can not come into plain view and judge that what road disconnects? this is to using and keeping in repair and all bring many inconvenience.

Summary of the invention

The utility model is at the problems referred to above, proposes that a kind of lamp of meter shows and shows fuse holder with the automobile audio band of digital display voltage value function.Now in conjunction with the following drawings, its feature is described as follows: the automobile audio band shows that fuse holder is by displaying block, display lamp, red led, small copper block, stifle, base, case, cartridge fuse, big copper block, the copper billet hold-down screw, the base plate screw, wiring board, compositions such as copper sheet, this fuse holder is a kind of four road fuse holders, it is characterized in that being fixed with a wiring board 16 at the inner chamber of base 6, positive source on the wiring board connects big copper block 10, through passage 13 and the displaying block 1 of sunkening cord, display lamp 2, red led 3 connects, peripheral hardware four line conductors are connected with four road small copper blocks 4 through the passage 13 of sunkening cord, be embedded with copper sheet 17 in base, the negative pole on the wiring board is connected with automobile chassis with base plate screw 12 by copper sheet 17.Between small copper block 4 that is provided with on the base and big copper block 10 cartridge fuse 9 is housed, they link to each other with binding post 14, and are fixedly connected by copper billet hold-down screw 11.Be buckled with stifle 5 below base 6, this is the passage 13 of sunkening cord between the two, is fixed by the screw that penetrates in the base plate screw 12, is buckled with case 7 above base 6.

This simple structure, use intuitively in case produce the blown fuse phenomenon, are just known and are broken at Na Lu, can also know magnitude of voltage.When voltage was lower than rated value, the red display lamp then can be not shinny.

Description of drawings

Fig. 1 is the utility model organigram;

Fig. 2 is the A-A cross-sectional schematic of Fig. 1;

Fig. 3 is that schematic diagram is looked on the left side of Fig. 1;

Fig. 4 is the wiring board circuit diagram among Fig. 1, is wiring board 16 in the frame of broken lines among Fig. 4, and 2, one red leds 3 of 1, four display lamp of a displaying block and an integrated package 18 are arranged on the wiring board.In the die cavity of base 6, the bottom is by stifle 5 fastenings by screw for whole wiring board, and it is fixing to penetrate base plate screw 12 by screw.

Sequence number and title among the figure: 1, displaying block, 2, display lamp, 3, red led, 4, small copper block, 5, stifle, 6, base, 7, case, 8, plug-in card, 9, cartridge fuse, 10, big copper block, 11, the copper billet hold-down screw, 12, the base plate screw, 13, the passage of sunkening cord, 14, binding post, 15, the lead access port, 16, wiring board, 17, copper sheet, 18, integrated package.

Embodiment

It is very convenient that the utility model is installed, as long as power line is connected to big copper block 10 and small copper block and by the screw of top, reinstalls cartridge fuse 9 by lead access port 15, lid is gone into case 7 and got final product.Operation principle is: display lamp is bright when working properly, and the red display lamp is also bright, and displaying block demonstrates the magnitude of voltage of work from start to finish.When work was undesired, displaying block demonstrated magnitude of voltage low or that exceed the quata.When which road cartridge fuse disconnected, that road display lamp did not work; When voltage was lower than rated value, red led did not work.When the client uses, by base plate screw 12 base is fixed on the automobile chassis, just reaches the ground connection purpose with screw.Whether the utility model can fuse, break at He Lu by fuse directly perceived, can also learn operational voltage value, shows key element, and the prompting user solves relevant issues immediately.And simple structure, easy to operate has certain application value.
