The automobile electric assembly control capsule of High Performance central authorities
Technical field
The utility model relates to a kind of vehicle electronics electric system, and specifically, the utility model relates to a kind of automobile electric assembly control capsule of High Performance central authorities.
Background technology
Traditional each the electrical equipment control device majority of automobile in home market is independent setting at present, disperse to install, perhaps be installed in mostly in the small space under the gauge panel, various relays, fuse, wire harness and connector parts under gauge panel, have been covered with, the mounting means line is numerous and diverse, fault is many, and inconvenience, maintenance difficult, poor reliability are installed; Institute's employing relay is contact and discrete component transistor type substantially; General electric control box power is less, can not adapt to the application of the high-power parts of part passenger vehicle, uses back passenger vehicle rate of breakdown height; And the controller producer that controls at individual parts is that cost-cutting adopts the common plastics goods more, and product design is not suitable for motor omnibus, and the fusing distortion causes car accident easily.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming of existing product in the market, provides a kind of multiple functional, reliable in quality, installation and maintenance are convenient, dustproof, applicable area is big a kind of automobile with the electric assembly control capsule of High Performance central authorities.
High Performance is the innovative technology that has adopted new unit; the field effect transistor (PCC) power; the Zero-ohm resistor new sensitive element; have and detect the advantage that loss is little, precision is high, speed of response is fast; realize the overload and the short-circuit protection of vehicle electronics electrical installation effectively, the wire fuse of the self-recovering function of composition and power field effect pipe solid-state relay.
Technical solution of the present utility model is as follows:
The utility model, it comprises body skin, wiring board, paster components and parts, field effect transistor solid-state relay, safety plate, safety plate fusing acoustooptic display alarm circuit, external plug light-emitting diode, current-limiting resistance, field effect transistor (PCC) power, positive source post; It is characterized in that various plug-in units all adopt corresponding Type B slot, are provided with jack corresponding to each plug-in card on shell, design 7 standby safety plate jacks and 5 standby diode jacks especially, safety plate is provided with over cap outward, is used for dustproof loss prevention; For the ease of assembling and maintenance, be provided with words identification in each jack correspondence position front; The line output of back is provided with the Connector Clip of different model, with difference circuit is installed and is avoided occurring dislocation, circuit card is installed on the outer casing base (12), outer casing base (12) designs some safety plate jacks with shell surface (11) combined circuit plate structure, relay jack (2), positive source binding post (5), standby diode wiring hole (7) and various line output connector (9).
The wire fuse of self-recovering function and field effect transistor solid-state relay, the principle of work of its field effect transistor (PCC) power: power supply is to the electric equipment supply regular power under the normal circumstances; When voltage surpassed setting value, overvoltage sample circuit signal was given action executing circuit, and action executing circuit turn-offs field effect transistor, thereby cut off the power supply of electric equipment, and the protection electric equipment is not subjected to an ancient egg-shaped, holed wind instrument bad; Recover normal voltage,, recover normal operation from new energized.
Circuit overcurrent protection has the voltage detection circuit of voltage between the probe field effect tube power element, the voltage signal that the rated current that surpasses forms on this element, converts the execution signal to, by action executing circuit field effect transistor is turn-offed; Play the overcurrent protection effect; The executive circuit principle of action executing circuit principle and excess voltage protection is identical.
The utility model is compared with prior art has following advantage:
1. simple for structure, with low cost, dependable performance;
2. it is little to have switching loss, the input impedance height, and driving power is little;
3. frequency-response data is good, the mutual conductance highly linear;
4. have negative temperature factor, do not have the secondary of bipolar power to pass problem, safety performance improves.
