Connector fault detection system

Abstract

The invention discloses a connector fault detection system, which comprises a backplane provided with N first connectors, a main board provided with N second connectors and a power management module,wherein the first pin of each first connector is connected with the second pin, and N is a positive integer; the second connectors and the first connectors are corresponding in a one-to-one mode, thethird pin, with the same position as the first pin, on each second connector is grounded, and the fourth pin, with the same position as the second pin, on each second connector is connected with the power management module for generating in-place signals when the second connector is normally connected with the corresponding first connector; and the power management module is used for receiving thein-place signals, and when all in-place signals meet a preset condition, normal crimping of all first connectors and all second connectors is judged, and a power-on process of the main board is started. Generation of fault is reduced, and the through-current capability and the normal communication between the main board and the backplane are ensured.

Description

technical field [0001] The invention relates to the field of connectors, in particular to a fault detection system for connectors. Background technique [0002] With the development of science and technology, storage systems and server systems are developing towards high-density, high-efficiency, and high-concentration designs. As the smallest and most basic unit in storage systems and server systems, connectors are used in various parts of the system. According to the connection method, the connector is divided into welding type, crimping type and winding type. With the upgrading of electronic products, the miniaturization and high reliability requirements of the connector, the way of crimping the connector is becoming more and more universal. Crimping refers to a process in which a metal and a connected metal piece are plastically deformed by using a crimping tool or equipment in a natural environment to form an integration of the metal structure. Since the cable of the c...

Problems solved by technology

[0003] At present, in the high-density system design, there are many connectors between the board and the board. The following situations will occur when crimping a large number of connectors. First, it is limited by the crimping area of ​​the crimping tool. The connector crimping is not complete, and the pins on the connector are not all crimped into the board; second, if a certain connector is placed in a crooked position, it may cause bending pins during the crimping process; third, The connector between the board and the board is incompletely inserted or incomplete contact. If any of the above-mentioned abnormal crimping conditions are not detected in time, after the power-on process of the board is started, the board will be affected. The flow capacity of the board will also affect the communication between the board and the board
