Abstract

The utility model, which relates to a displayable insurance tablet of a car sound in a field of car sound electric fittings, is designed according to the problem that the present insurance tablet only has a break function without a voltage display function of a light and a number. The key point is that a circuit board which is fixed in an internal cavity of a bottom base is provided with components, such as a display block, a display light and a red indication light, and the outside of the circuit board is provided with wires of four channels to connect with copper blocks of each channel through a line embedding channel, and a copper tablet is embedded in the bottom base, and a negative line on the circuit board is connected to a car chassis through the copper tablet and a bottom plate screw. The power wire which is connected to a large copper lock and a small copper block through a wire inlet is fixed by the above screws, then the utility model is completed by arranging the insurance tablet in the copper blocks and covering a cover. When the insurance tablet base is fused, the indication light is gone; when the voltage is lower than the rated value, the red indication light is gone. The utility model which can suggest the users solve the related problems is simple in structure, visual in use, convenient in operation and has a certain application value.

Description

The small passenger car audio tape shows the insurance bar

Affiliated technical field

The utility model relates to auto audio equipment electrical accessorie field, is that a kind of small passenger car audio tape shows insurance bar, model XA-1372.

Background technology

At present, small passenger car sound equipment insurance bar only has cut-out function, and operating voltage surpasses rated voltage promptly automatically with safety plate fusing, and does not have the function of lamp demonstration and numeric display magnitude of voltage.Under the dim and remote situation of weather, can not see obviously whether safety plate 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, propose the insurance bar of a kind of lamp demonstration of meter and band numeric display magnitude of voltage function, and simple structure, use are intuitively, in case produce the blown fuse phenomenon, just know and break at Na Lu, can also do you know how much is magnitude of voltage? when voltage was lower than rated value, the red display lamp then can be not shinny, and its particular content is seen following explanation.

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 scheme drawing is looked on the left side of Fig. 1.

Sequence number and title among the figure: 1, displaying block, 2, display lamp, 3, red indicating light, 4, small copper block, 5, stifle, 6, base, 7, case, 8, plug-in card, 9, safety plate, 10, big copper block, 11, the copper billet fix screw, 12, the base plate screw, 13, the passage of sunkening cord, 14, connection terminal, 15, the lead access port, 16, wiring board, 17, copper sheet.

Now in conjunction with the accompanying drawings, its feature is described as follows: the small passenger car audio tape shows that the insurance bar is by displaying block, display lamp, red indicating light, small copper block, stifle, base, case, safety plate, big copper block, the copper billet fix screw, the base plate screw, wiring board, compositions such as copper sheet, this insurance bar 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, this plate is provided with displaying block 1, display lamp 2, red indicating light 3 components and parts such as grade, peripheral hardware four line conductors are connected with each road small copper block by the passage 13 of sunkening cord, be embedded with copper sheet 17 in base, the negative wire on the wiring board is grounded to the small passenger car chassis by copper sheet 17 and base plate screw 12 exactly.Be provided with small copper block 4 and big copper block 10 on base, safety plate 9 is housed between small copper block and the big copper block, they link to each other with connection terminal 14, and are fixing by copper billet fix screw 11.Be buckled with stifle 5 below base, this is provided with the passage 13 of sunkening cord between the two, and is provided with base plate screw 12, is buckled with case 7 above base.

The specific embodiment

It is very convenient that the utility model is installed, as long as power lead is connected to big copper block 10 and small copper block and by the screw retention of top, reinstalls safety plate 9 by lead access port 15, lid is gone into case 7 and got final product.Principle of work 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.When the work mal, displaying block demonstrated numerical value low or that exceed the quata.When which road safety plate disconnected, that road display lamp did not work; When voltage was lower than rated value, red indicating light did not work.When the client uses, by base plate screw 12 base is fixed on the small passenger car chassis, just reaches the ground connection purpose with screw.Whether the utility model can fuse, break at He Lu by safety plate 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.
