Different types and colors of jumpers, with two individual black jumper pins on the left for scale. In electronics and particularly computing, a jumper is a short length of conductor used to close, open or bypass part of an electronic circuit.
Humidity and aggressive chemicals can cause corrosion of the packaging materials and leads, potentially breaking them and damaging the inside parts, leading to electrical failure. Exceeding the allowed environmental temperature range can cause overstressing of wire bonds, thus tearing the connections loose, cracking the semiconductor dies, or ...
If the bent pin is touching another contact (or two other contacts), then there is an electrical short between two (or three) paths (Figure 3). In some very commonly used miniature D connectors, it is possible that a bent pin can touch two neighboring contacts plus a grounded connector shell, thus shorting chassis ground to three electrical ...
Left: 20-way grey ribbon cable with wire for pin 1 marked red, insulation partly stripped. Right: 16-way rainbow ribbon with IDC connector. IDC D-sub connectors DE-9 (male) and DA-15 (female) Twisted ribbon cable used for Parallel SCSI connections. A ribbon cable is a cable with many conducting wires running parallel to each other on the same ...
Cable management refers to management of electrical or optical cable in a cabinet or an installation. The term is used for products, workmanship or planning. Cables can easily become tangled, making them difficult to work with, sometimes resulting in devices accidentally becoming unplugged as one attempts to move a cable.
Electrical breakdown in an electric discharge showing the ribbon-like plasma filaments from a Tesla coil.. In electronics, electrical breakdown or dielectric breakdown is a process that occurs when an electrically insulating material (a dielectric), subjected to a high enough voltage, suddenly becomes a conductor and current flows through it.
After a 14-hour ordeal, all eight people, including six children and two adults, who were stranded on a cable car dangling hundreds of feet over a valley in northwest Pakistan have been rescued ...
High voltage is defined as any voltage over 1000 volts. [3] Those of 2 to 33 kV are usually called medium voltage cables, those over 50 kV high voltage cables.. Modern HV cables have a simple design consisting of a few parts: the conductor, the conductor shield, the insulation, the insulation shield, the metallic shield, and the jacket.
