Abstract
The utility model discloses a wiring harness device with the controlling and protecting functions, which is mainly applicable to the technical field of excavators. The wiring harness device comprises a control bus, a relay, a fuse, a power supply and a wiring harness, wherein the control bus is electrically connected with the wiring harness used for controlling important electrical components by a protecting device consisting of the relay, the fuse and the power supply. The wiring harness device has the benefits of being convenient to operate, separately protecting the electrical components by the control circuit, and simultaneously avoiding influence of failure of one part on multiple parts.
Description
Technical field
The utility model relates to a kind of wire harness device, specifically is a kind of wire harness device with control and defencive function, mainly is applicable to the excavator equipment technical field.
Background technology
Present excavator both domestic and external is generally to intellectuality, and unmanned and high performance development is the various control devices widespread usage of core with the microprocessor, in order to protect these electric equipments, has adopted the electronic component protection circuit in the excavator electrical system.For achieving the above object, excavator often adopts the master switch of battery relay system, can prevent that line failure from causing unnecessary economic loss.But place's wire harness fault causes chain reaction easily, such as relevant wire harness short circuit, loose contact or when opening circuit, can cause the damage of the electric elements that other wire harness connects simultaneously, and investigate loaded down with trivial details.
The utility model content
At above-mentioned existing technical problem, the utility model provides a kind of wire harness device with control and defencive function, and each big wire harness is adopted relay control respectively, by control circuit each big electric elements is played the separately effect of protection.
The utility model is achieved through the following technical solutions for achieving the above object: a kind of wire harness device with control and defencive function comprises control bus, relay, fuse, power supply, wire harness; The signal end of control bus is connected with relay, and relay is connected with wire harness by fuse, and wire harness links to each other with power supply with fuse by relay.The utility model mainly is useful in the electrical system of excavator, and control bus is by mainly being electrically connected by relay, fuse and power supply protective device of forming and the wire harness of controlling important electric elements.
The beneficial effects of the utility model are: each big wire harness is separately adopted relay control, and not only handiness, and can also protect electric elements or parts by control circuit, control bus is not damaged; Effectively avoided a place that fault is arranged, the situation that many places are involved, the normal application life of assurance electric elements; Be convenient to accurately, promptly investigate fault.
Description of drawings
Fig. 1 is an electric theory diagram of the present utility model
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises control bus, relay, fuse, wire harness, power supply; The signal end of control bus is connected with relay, and relay is connected with wire harness by fuse, and wire harness links to each other with power supply with fuse by relay.
In the excavator electrical system; the device and wire harness electric connection with control and protective effect of control bus by mainly forming, each bar wire harness by relay, fuse and power supply respectively with the vitals of excavator such as starter, monitor, preheating device, the electric connections such as electromagnetic valve, running gear, swing arm lamp, air-conditioning, loudspeaker of stopping working.The break-make that this device is not only controlled the place circuit is the switch of the electric elements of wire harness connection; and protection control bus and the controller that is attached thereto etc.; make every wire harness relatively independent simultaneously; avoided a place that fault is arranged; the situation that many places are involved protects important electric elements to avoid infringement by control circuit.This adopts the excavator of the higher microprocessor (computer) of price particularly important to electric elements.
