WATERTIGHT ELECTRICAL CONNECTION SYSTEM TO FLAT-WIRE CONDUCTORS OF A FLEXIBLE PRINTED CIRCUIT

A watertight electrical connection system to flat-wire conductors of a flexible circuit is described including a watertight electrical connector that houses connector terminals within a cavity. A contact surface of the watertight electrical connector is configured to mate with a connection area on a surface of the flexible circuit. The connection area is of variable thickness. A seal surrounds an opening to the cavity to form a watertight connection between the connector terminals and one or more of the flat-wire conductors within the connection area on the surface of the flexible circuit. A retainer fits over the flexible circuit and onto the watertight electrical connector to compress the seal and form the watertight connection between the surface of the flexible circuit and the contact surface, which is of variable thickness.

BOOT AND CONNECTOR ASSEMBLY
20200388954 · 2020-12-10 ·

The present invention relates to a boot and connector assembly. The boot has a through hole passing therethrough and a boot body enclosing the through hole, the boot body comprising: a neck sealing portion presenting a substantially cylindrical shape, wherein the neck sealing portion has an inner diameter maintained substantially constant; a body portion located at the proximal side of the neck sealing portion and presenting a generally cylindrical shape, wherein the body portion has an inner diameter and an outer diameter that are both greater than the inner diameter and the outer diameter of the neck sealing portion; and a gap passing portion connecting the neck sealing portion to the body portion and having a substantially frustoconical shape, wherein the gap passing portion has an inner diameter gradually increasing from the inner diameter of the neck sealing portion to the inner diameter of the body portion, and an outer diameter gradually increasing from the outer diameter of the neck sealing portion to the outer diameter of the body portion. The boot of the present disclosure effectively solves the problem that the boot interferes with other components so that the boot is unable to extend to the antenna panel when the mounting space is small, and also has the advantages of simple to manufacture, convenient to mount and high efficiency.

Gas resistant pothead system and method for electric submersible motors

A gas resistant pothead system and method for electric submersible motors. A gas resistant pothead system includes a lead foil wrapped motor lead cable (MLE) extending through a pothead, a sleeve of an insulator block inside the pothead, the sleeve including gold plating and lead-foil wrapping over the gold plating, and a lead-to-gold seal formed between the gold plating of the sleeve and the lead foil wrapping over the gold plating. A method of creating a seal to gas around a power cable connection to a downhole electric submersible motor includes wrapping lead foil around a MLE extending through a pothead, continuing the lead foil wrapping around a gold-plated sleeve of an insulating block inside the pothead, mechanically reinforcing the lead foil with an encapsulant, and bonding the lead foil to the gold plating of the insulating block.
