Abstract

The utility model relates to a display safety lever base arranged on the car sound in the field of the electric fittings of the car sound which is designed aiming at that the prior safety lever base only has the function of circuit break and has no function of displaying the value of the voltage with lamp and number. The utility model is mainly characterized in that a circuit board is fixed in a cavity of a base and elements such as a display block, a display lamp, a red indicator lamp, etc., are arranged on the circuit board; the two ways of wires arranged externally are connected with each way of small copper-block through a catgut embedding channel. Copper strips are arranged in the base; a negative line on the circuit board is grounded to the chassis of the automobile through the copper strips and a screw of a bottom plate. A power cord is connected to the largeger copper blocks and the smaller copper blocks through wires and is fixed by a bolt at the upward side\, and then the safety lever is arranged in and an enclose is covered. When the safety lever is burnt out, the display lamp does not shine; when the voltage is lower than a rated value, a red indicator lamp does not shine. The utility model can prompt the user to solve the related problems instantly and has the advantages of simple structure, intuitive use, convenient operation and certain value of application.

Description

The car audio tape shows the insurance bar

Affiliated technical field

The utility model relates to car sound equipment electrical accessorie field, is that a kind of car audio tape shows insurance bar, model XA-1370.

Background technology

At present, 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 safety plate fusing 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, safety plate, 9, big copper block, 10, copper billet fix screw, 11, the base plate screw, 12, connection terminal, 13, the passage of sunkening cord, 14, lead access port, 15, wiring board, 16, copper sheet.

Now in conjunction with the accompanying drawings, its feature is described as follows: the auto audio equipment band 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 two-way insurance bar, it is characterized in that being fixed with a wiring board 15 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 two line conductors are connected with each road small copper block by the passage 13 of sunkening cord, be embedded with copper sheet 16 in base, the negative wire on the wiring board is grounded to passenger-car chassis by copper sheet 16 and base plate screw 11.Be provided with small copper block 4 and big copper block 9 on base, safety plate 8 is housed between small copper block and the big copper block, they link to each other with connection terminal 12, and are fixing by copper billet fix screw 10.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 11, 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 9 and small copper block and by the screw retention of top, reinstalls safety plate 8 by lead access port 14, 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, and 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 11 base is fixed on the 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.
