The molded bonding layer bonds the outer casing to the inner film. In addition, a metal spring latch is mounted on the outer casing.

A connector includes a wire harness, and a connector main body to which the wire harness is attached. The connector main body includes a first substrate stack in which a plurality of first substrates are held in a vertically stacked state, a first bottom substrate that forms the lowermost first substrate of the first substrate stack and includes a coupling post extending upward from an upper face, and a second substrate stack that is arranged on a lateral side of the first substrate stack and in which a plurality of second substrates are held in a vertically stacked state. At least one of the plurality of second substrates included in the second substrate stack is provided with a coupling hole (a through hole provided in the second substrates of the second layer, the fourth layer, and the sixth layer) that can be fitted to the coupling post (a right post).

A receptacle connector includes an insulative receptacle housing, two rows of receptacle contacts retained to the receptacle housing, a one-piece metallic shell member retained to the receptacle housing and having a circumferential structure continuously surrounding the receptacle housing wherein a shielding/grounding member unitarily extends from the shell member and into an center island of the receptacle housing to separate the two rows of contacts in the transverse direction. A plug connector includes an insulative plug housing, two rows of plug contacts, and a pair of grounding blocks at two ends. During mating, two opposite ends of the shielding/grounding member mechanically and electrically connect to the pair of metallic grounding blocks or locking members, respectively.

A counter connector for mating with a connector has a hollow cylindrical housing. The counter connector includes at least two, and preferably three, of the following three types of locking means for locking the counter connector to the connector: (A) one that is arranged on a perimeter on a cylindrical surface of the housing or of a sleeve located inside the housing, a counter engagement part in the form of a groove, a collar, or a series of radially extending apertures, recesses or protrusions, the counter engagement part being adapted to engage with at least one engagement part or at least one latching part of the connector. (B) one that has a counter latching part that can be deflected elastically in a radial direction of the counter connector and comprises at least one of a radially extending groove, collar, aperture, recess or protrusion adapted to engage with a latching part of the connector. (C) one where a counter thread is adapted to engage with a thread of the connector. Systems can include the counter connector and at least one connector that can be mated with the counter connector, wherein the connector is of one of the following three types: a) a push-pull connector; b) a break-away connector; and c) a threaded connector.

A connector structure with pull tap includes a plug, a latch and a pull tap. The plug includes a main body and a protruding structure. The protruding structure is extended outward from the main body and includes a groove. The latch includes a fixed arm and an elastic arm. The fixed arm has an installing structure and an opening, and the installing structure is connected to the groove of the protruding structure. The elastic arm is extended from the fixed arm and hangs above the fixed arm. The pull tap includes a tap body and a first end located at one end of the tap body. The pull tap passes through the opening of the fixed arm and the elastic arm is arranged on the first end to fix the first end on the elastic arm.

An arc prevention system including a jack having a receptacle, a modular connector sized to be positioned in the receptacle of the jack, the modular connector including a plurality of contacts, with at least two of the contacts creating an energized electrical path with an external power source in electrical communication with the external power source, a latch extending from a top surface of the modular connector, a switching unit positioned on the latch, a plug unit positioned between the latch and the jack that prevents the modular connector from moving out of the receptacle, a control circuit in electrical communication with switch and the at least two energized contacts, where the electrical path between the control circuit and the switching unit is energized when the plug engages the switching unit on the latch, and the control circuit adjusts the energized electrical path to a predetermined electrical level.

A connector structure includes a hood formed in a housing and having a bottomed tubular shape, a mating hood formed in a mating housing and fitted inside the hood, a plate spring member made of metal and accommodated in a bottom of the hood, a playing regulating member, a mating hood tip end inclined surface formed at a tip end of the mating hood in a fitting direction and inclined to a tube inner side or a tube outer side, and a playing regulating protrusion. The playing regulating member is provided in an opposite side against the bottom with the plate spring member interposed therebetween and is urged by the plate spring member in a direction opposite to a fitting direction against the mating hood.

Systems and methods of deploying seismic data acquisition units from a marine vessel are disclosed. The system can include a mechanical attachment device comprising a cavity formed by interlocking a first member and a second member. Protrusions located on the first member and second member can increase the coefficient of friction between a rope and the mechanical attachment device responsive to an increase in tension on the rope. A lanyard can couple a seismic data acquisition unit to the mechanical attachment device.

A connector assembly device includes a connector element and a connector position assurance (CPA) device mounted to move relative to the connector element between a delivery position and a locking position. The connector element includes a first locking device and a second locking device. The CPA device includes a locking lance that has an associated first locking device configured to implement a first form-fitting connection with the first locking device of the connector element and an associated second locking device configured to implement a second form-fitting connection with the second locking device of the connector element in the locking position. The form-fitting connections prevent any movement of the CPA device in a direction from the locking position towards the delivery position and take place in different planes.
