Abstract
The utility model discloses an electrical failure simulation test box for a vehicle, which comprises a box body. An operation panel, an upper circuit board and a lower circuit board are sequentially arrayed in the box body from top to bottom; the operation panel is attached onto the upper circuit board; the upper circuit board is in circuit connection with the lower circuit board through a lead; and a socket and a plug are arranged on the lower circuit board, wherein the socket is used for being connected with a vehicle wire harness, and the plug is used for being connected with an ECU (electric control unit). When the test box is in specific application, a test point can be provided for each wire, so that an engineer can analyze signals in terms of time domain and frequency domain by using professional equipment such as an oscilloscope, a spectrum analyzer and the like. Besides, specific interference can be conveniently exerted to signal lines, so that stability and fault tolerance of the electric control unit of the vehicle are judged. The electrical failure simulation test box has the advantages of convenience in use, comprehensive functions and the like, and the engineer can simulate functions such as connection and disconnection of the wire harness, power or earth circuit breaking and the like through simple operation of a toggle switch.
Description
Technical field
The utility model provides the chamber of a kind of vehicle electric fault simulation.
Background technology
At present; Existing chamber can only be accomplished the fault simulating function of single or minority mostly, such as the simulation that can only be applied to the wire harness break-make that has, and the function that can accomplish the wire harness break-make that has; But need to use independent special small plug to accomplish (plug wire harness for logical, pull up) to disconnected.If accomplish the function of wire harness to power supply short circuit or shorted to earth, then need use other lead that the respective terminal on the small plug and power supply or ground short circuit are accomplished, in case bother very much and the mistake consequence hardly imaginable.Simultaneously the Developmental Engineer need carry a large amount of attached parts, loses easily and heaviness is not easy to carry.
Summary of the invention
To above-mentioned prior art, all be the parts of special type because above-mentioned similar products of the prior art use, not strong with component universality on the market; Even do not have market sale at home, therefore, the design aim of the utility model just is to use existing parts; The convenient purchase and later maintenance, and can make cost be able to effective control, therefore; The utility model provides the chamber of a kind of vehicle electric fault simulation; It is easy to use, complete function, the function that the operation of slip-stick artist through simple toggle switch just can simulate break-make to wire harness, power supply or ground are opened circuit etc.
The utility model is realized through following technical scheme:
The chamber of a kind of vehicle electric fault simulation; Comprise casing; Be arranged in order from top to bottom in the casing and be provided with guidance panel, go up layer circuit board and lower circuit plate; Guidance panel is attached on the layer circuit board, and last layer circuit board is connected with lower circuit plate circuit through lead, and the lower circuit plate is provided with the socket and the plug that is used to be connected ECU that is used to connect vehicle harness.
The vehicle electric fault simulation chamber body of the utility model is an openable case structure; Can see guidance panel after opening; Guidance panel is the PVC facial mask that is printed on the words identification of respective switch institute corresponding lead, and the hole of vertical correspondence is arranged on guidance panel and the last layer circuit board.The PVC facial mask of making is attached on the layer circuit board exactly; Toggle switch and toggle switch are stuck on the hole of layer circuit board and are exposed at the outside of facial mask like this; Wherein toggle switch is the pilot break-make, and toggle switch is that control is to power supply, ground short circuit.Toggle switch all on each bar lead, but toggle switch is the function demand assigned (toggle switch and toggle switch are prior art) according to line.The pairing lead of each toggle switch has all clearly printed on guidance panel; All there is a pad each toggle switch following; This pad is directly to link on the lead, and the slip-stick artist can utilize instruments such as oscillograph, signal generator and spectrum analyzer to carry out that signal injects through this pad and signal time domain, frequency-domain analysis.
The lower circuit plate is the terminal block of whole test case, during use, can contain through the plug that is used to connect ECU on the one hand and is inserted into vehicle electrically controlling unit (ECU); Can vehicle harness be plugged through the socket that is used to connect vehicle harness on the other hand, this has just realized connecting both transition linkage functions.In order to make the slip-stick artist in the process of operation, can find the pairing switch of target lead apace; Corresponding words identification is all arranged on the guidance panel; And according to the mode that is suitable for operating the residing zone of various switches is divided, the most often the switch of operation is placed on the position that is prone to most touch.
The chamber of the utility model must be that an end connects the vehicle electrically controlling unit through plug on the wire harness annexation as " intermediate link " that gets involved vehicle electrically controlling unit and wire harness, and the socket of itself is connecting vehicle harness, plays a part this forming a connecting link.
The chamber of the utility model can provide test point to every single line when concrete the application, the slip-stick artist just can use professional equipments such as oscillograph, spectrum analyzer signal to be carried out the analysis of time domain and frequency domain like this; And can apply specific interference to signal wire easily, in order to the stability of judging the vehicle electrically controlling unit and fault-tolerant ability the signal voltage no to scale scope of cooling-water temperature sensor (for example make).In addition, utilize test point to carry out the experiment that overlaps between line through lead, because in the vehicle of reality, to take place to overlap between line be a kind of most common failure of vehicle harness owing to the insulated hull of lead galls.
The chamber of the utility model is a kind of generation instrument of vehicle electric fault; When using its specific function, can produce corresponding malfunction; (being that each switch is in initial position) then can not produce any influence to the normal function of wire harness under normal condition, and chamber at this moment only has been equivalent to wire harness " prolongation " one section.
The utlity model has advantages such as easy to use, complete function, the function that the operation of slip-stick artist through simple toggle switch just can simulate break-make to wire harness, power supply or ground are opened circuit etc.
