Abstract
The utility model relates to a binding post row that electrical equipment used specifically is a circuit trouble binding post row, including setting up two terminals in the casing, still include current detection chip and data display module, two wiring ends of current detection chip respectively with two terminal connections, the output of current detection chip and data display module's input are connected, and data display module installs on the casing, and the specific model of current detection chip is MAX 472. The utility model discloses a solve the problem that faults such as short circuit, open circuit, ground connection, virtual connection that appear in the wiring of consumer are difficult to be looked for, provide a line fault detection terminal row, made things convenient for the seeking of staff to the trouble to and fall fault handling, guaranteed the normal operating of equipment.
Description
Technical field
The utility model relates to the connecting terminal block that electrical equipment uses, and is specially a kind of line fault connecting terminal block.
Background technology
Electric equipment control loop wiring circuit is more, intricate, the wiring distance is different in size, therefore in wiring, often use connecting terminal block, as shown in Figure 1, the enclosure interior of connecting terminal block is provided with two binding posts 1, also be connected with wire between two binding posts 1, two binding posts of connecting terminal block by and be connected the connection jaws 2 that is communicated with are connected after the wiring of a distinct device connects, with these two different device lines connections; The effect of connecting terminal block is exactly that circuit with different electric equipments is connected, play the effect of transmission voltage or electric current, also so that the wiring between the electric equipment is attractive in appearance, because electric equipment wiring circuit is many, complexity, wiring distance, occur easily short circuit in the circuit, open circuit, the fault such as ground connection, virtual connection, and that these troubleshootings are got up is all cumbersome, and line fault can not in time be removed, so that the electric equipment cisco unity malfunction.
Summary of the invention
The utility model for the short circuit that occurs in the wiring circuit that solves electric equipment, open circuit, the fault such as ground connection, virtual connection and the problem that is not easy to search provides a kind of line fault detection terminal row.
The utility model is to adopt following technical scheme to realize: line fault detection terminal row, comprise two binding posts that are arranged in the housing, comprise current detecting chip and data disaply moudle, two terminals of current detecting chip respectively with are connected binding post and connect, the output terminal of current detecting chip is connected input end and is connected with data disaply moudle, data disaply moudle is installed on the housing.
During use, the connection to a certain loop has been finished in the Access Control loop of contacting respectively of two binding posts in the line fault detection terminal row; If when short trouble occurring in this connection line, the current value that shows on the data disaply moudle on the terminal row changes from small to big; If when open circuit fault occurring in the circuit, the current value that shows on the data disaply moudle on the terminal row is zero; If when earth fault occurring in the circuit, it is large that the current value that data disaply moudle shows on the terminal row becomes; If when occurring the virtual connection fault in the circuit, the current value that shows on the data disaply moudle on the terminal row is suddenly big or suddenly small; On-the-spot technician just can process circuit according to these different situations, has made things convenient for searching of breaking down in the circuit.Above-mentioned current detecting chip is well-known to those having ordinary skill in the art.
Above-mentioned line fault detection terminal row, described current detecting chip model is MAX472, this chip current detection sensitivity is high, improves the efficient of troubleshooting.
The utility model for the short circuit that occurs in the wiring that solves consumer, open circuit, problem that the fault such as ground connection, virtual connection is not easy to be searched, a kind of line fault detection terminal row is provided, made things convenient for staff's searching fault, and reach fault handling is fallen, guaranteed the normal operation of equipment.
