Abstract
The utility model discloses a fireproof speed-regulation resistance for an automotive fan, which comprises a first shell, wherein one end of the first shell is integrally connected with a second shell; a through hole is formed in the second shell; a resistance body is arranged in the first shell; a fuse is arranged in the second shell; the resistance body is connected with the fuse in series through a first lead; the first shell is connected with a conducting line; the resistance body and the fuse are connected with the conducting line respectively through a second lead and a third lead; the front end of the guide line is connected with an amphenol connector. The fireproof speed-regulation resistance reduces the occurrence rate of a fire disaster of a heat dissipation circuit to a great extent and has the advantages of low cost, high reliability and universality, and long service life.
Description
Technical field
The utility model is specifically related to a kind of automobile fan fire prevention speed adjusting resistance, belongs to electronic device field.
Background technology
Along with improving constantly of socioeconomic development and people's living standard, the recoverable amount of private car in entire society improves constantly; Current automotive interior is provided with radiator, and because radiator need to dispel the heat with fan, fan carries out speed governing by alignment circuit again simultaneously; The current speed governing for fan adopts series resistance in fan electromotor circuit more, reduces fan electromotor both end voltage and reduces the object of fan power, thereby reduce rotation speed of the fan by electric resistance partial pressure; Due to fan, electric current is larger in the course of the work, causes the electric current that passes through in resistance larger, thereby causes the power that consumes on resistance larger, makes resistance temperature too high, and naked light easily occurs, and produces fire.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of reliable in structure, long service life, can effectively ensure that radiation fan on vehicle alignment circuit can not produce the automobile fan fire prevention speed adjusting resistance of fire hazard in the course of the work.
Fire prevention speed adjusting resistance for automobile fan of the present utility model, comprises the first housing; Described first housing one end is made into integration and is connected with the second housing; On described the second housing, be provided with through hole; In described the first housing, be provided with resistance body; In described the second housing, be provided with fuse; Described resistance body is connected in series by the first lead-in wire and fuse; Described the first housing is connected with wire; Described resistance body is connected with wire with the 3rd lead-in wire by the second lead-in wire respectively with fuse; Described wire front end is connected with binding post.
Further, described the first housing and the second housing are cylindric.
Further, described through hole is provided with 4, and is evenly distributed around the second housing.
Further, the fusing-off temperature of described fuse is 240 DEG C.
The utility model beneficial effect: a kind of reliable in structure of the present utility model, long service life, can effectively ensure that radiation fan on vehicle alignment circuit can not produce the automobile fan fire prevention speed adjusting resistance of fire hazard in the course of the work; In the time using the utility model, the utility model is serially connected in the circuit of radiator fan; As the utility model in the course of the work, temperature on fuse is during higher than the rated temperature of fuse, and fuse cuts off fan power supply, and fan quits work, thereby make the temperature of the utility model internal resistance body no longer increase, effectively prevented the generation of fire; The utility model has reduced the incidence of radiating circuit fire to a great extent, the utlity model has that cost is low, reliability is high, the advantage of long service life and highly versatile simultaneously.
Brief description of the drawings
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
Fire prevention speed adjusting resistance for a kind of automobile fan as shown in Figure 1, comprises the first housing 1; Described first housing 1 one end is made into integration and is connected with the second housing 2; On described the second housing 2, be provided with through hole 10; In described the first housing 1, be provided with resistance body 3; In described the second housing 2, be provided with fuse 4; Described resistance body 3 is connected in series with fuse 4 by the first lead-in wire 5; Described the first housing 1 is connected with wire 8; Described resistance body 3 is connected with wire 8 with the 3rd lead-in wire 6 by the second lead-in wire 7 respectively with fuse 4; Described wire 8 front ends are connected with binding post 9.
Wherein, described the first housing 1 and the second housing 2 are cylindric; Described through hole 10 is provided with 4, and is evenly distributed around the second housing 2; The fusing-off temperature of described fuse 4 is 240 DEG C.
A kind of reliable in structure of the present utility model, long service life, can effectively ensure that radiation fan on vehicle alignment circuit can not produce the automobile fan fire prevention speed adjusting resistance of fire hazard in the course of the work; In the time using the utility model, the utility model is serially connected in the circuit of radiator fan; As the utility model in the course of the work, temperature on fuse is during higher than the rated temperature of fuse, and fuse cuts off fan power supply, and fan quits work, thereby make the temperature of the utility model internal resistance body no longer increase, effectively prevented the generation of fire; The utility model has reduced the incidence of radiating circuit fire to a great extent, the utlity model has that cost is low, reliability is high, the advantage of long service life and highly versatile simultaneously.
Embodiment recited above is described preferred implementation of the present utility model, not design of the present utility model and scope is limited.Do not departing under the prerequisite of the utility model design concept; various modification and improvement that this area ordinary person makes the technical solution of the utility model; all should drop into protection range of the present utility model; the technology contents of the utility model request protection, has all been documented in claims.
