An analysis method and an analysis system for optimization of a high-speed signal connector are provided. The method includes: setting an excess portion of each of a pin and a pad in the high-speed signal connector to be different lengths; equating the excess portion of each of the pin and the pad with an inductor and a capacitor; analyzing performance of connectors having different lengths of the excess portion of the pin and different lengths of the excess portion of the pad, and comparing performance parameters of the connectors; and obtaining a length of the excess portion of the pin and a length of the excess portion of the pad in a case of an optimal performance parameter, and cutting the pin and the pad based on the obtained lengths.

An electrical connector is capable of performing stable inspection without affecting an extraction force of a connector engagement portion. The electrical connector includes a housing having an electrical insulation property, an internal terminal held by the housing, and an external terminal held by the housing, with the external terminal to be electrically connected to a ground. The external terminal includes a fitting portion having a first engagement wall portion at one side and having a second engagement wall portion at the other side in a plan view from a connector insertion/extraction direction. A first engagement portion is formed at the first engagement wall portion, and a second engagement portion is formed at the second engagement wall portion.

A work machine includes a control device including a lead position detecting section to detect a lead position which is positions of a pair of leads based on imaged data imaged by an imaging device, a first detecting region setting section to set, based on the lead position detected by the lead position detecting section, a first detecting region outside the pair of leads including a part of a bottom section outside the pair of leads, a second detecting region outside the pair of leads, being opposed to the first detecting section across the pair of leads including a part of the bottom section, and a polarity determining section configured to determine the polarity of the pair of leads based on whether the mark portion exists in each of the first detecting region and the second detecting region.

A test device for a high-speed/high-frequency test. The test device includes: a conductive block which includes a probe hole; at least one signal probe which is supported in an inner wall of the probe hole without contact, includes a first end to be in contact with a testing contact point of the object to be tested, and is retractable in a lengthwise direction; and a coaxial cable which includes a core wire to be in electric contact with a second end of the signal probe. With this test device, the coaxial cable is in direct contact with the signal probe, thereby fully blocking out noise in a test circuit board.

Motherboard connector failures can be predicted. An embedded controller can be employed on the motherboard to monitor when devices are connected to and disconnected from the motherboard's connectors. The embedded controller can maintain an event log and connector information in which it counts the number of times a device is connected to/disconnected from a connector. The BIOS can leverage the event log and the connector information to notify an end user to take action to correct or prevent possible corrosion. Training records may also be employed to predict connector failure. The training records can track and maintain baseline and periodic device training attributes. When the periodic training attributes deviate from the baseline training attributes, an end user can be notified to take action to remove corrosion.

One embodiment is directed to detecting that a cable has been connected to a port of patching equipment and detecting that the cable is no longer connected to said port. In response to detecting that the cable is no longer connected, information associated with fixed cabling coupled to said port that is captured by a cable tester is downloaded to a controller. The downloaded information is associated with said port and the downloaded information and association information is locally stored at the controller. The locally stored information can then be used to create and/or populate objects in a database. Another embodiment is directed to including a storage device and a wireless interface in patching equipment or other equipment such as an outlet or consolidation point for use in writing information to the storage device and reading information from the storage device via the wireless interface. Other embodiments are disclosed.
