Abstract
Description
Technical Field
[0001] The utility model relates to a troubleshooting test fixture, in particular to a troubleshooting test fixture on a signal box of an electromechanical system. Background Art
[0002] When a product is returned to the factory due to a fault, in most cases the retest result is that the fault does not recur, resulting in the factory being unable to analyze and locate the specific cause of the fault. In order to locate the specific cause of the product failure, it is necessary to analyze the cause on the aircraft in combination with the actual use conditions of the product. Therefore, a special product and aircraft transfer connection fixture must be designed and manufactured to assist external test tools in measuring the voltage and current signals between the product and the aircraft. Utility Model Content
[0003] The utility model aims to solve the technical problem of how to design a special product for assisting external testing tools, measuring voltage and current signals between the product and the aircraft end, and connecting the fixture to the aircraft end.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] A troubleshooting test fixture for an electromechanical system signal box comprises a wire A, a heat shrink identification sleeve A, a product-end circular electrical connector, an aircraft-end circular electrical connector, a wire B, a heat shrink identification sleeve B, a heat shrink sleeve and a rectangular connector; both ends of the wire A pass through the heat shrink identification sleeve A and are respectively connected to the product-end circular electrical connector and the aircraft-end circular electrical connector; a wire B is further branched from the wire A, one end of the wire B passes through the heat shrink identification sleeve B, and then passes through the heat shrink sleeve and is connected to the rectangular connector.
[0006] The beneficial effects of adopting the above technical solution are:
[0007] The utility model is mainly used as a test fixture for assisting in troubleshooting on a product machine, and has the advantages of being easy to carry, simple and reliable to connect, and being able to assist test equipment in measuring the actual working voltage and current value of the product without opening the product cover.
