A battery connection device includes a base end connector, a battery end connector and a waterproof rubber ring. The base end connector includes a base end terminal module. The base end terminal module is mounted to the base end connector. The base end connector has a ring-shaped holding groove. The holding groove surrounds the base end terminal module. The battery end connector is docked with the base end connector. The battery end connector includes a base plate, and a battery end terminal module mounted on the base plate. The base end terminal module is docked with the battery end terminal module. The waterproof rubber ring is mounted between the base end connector and the battery end connector.

A cable connector includes a cable, a cover body, and a sealing member. The cable has multiple core wires and a cover layer. The cover layer covers a part of each core wire. An uncovered part of each core wire defines a naked section. The cover body covers the cover layer and a part of each naked section, and is formed with a hole corresponding to positions of the naked sections. The sealing member is disposed in the hole and seals a gap between any two of the naked sections adjacent to each other. Therefore, liquid such as water may be prevented from infiltrating into the connector along a periphery of each core wire.

The seal spring of the present invention has a dual functionality. The seal spring provides both a sealing property and spring function in use within an electrical connector system, which is accomplished by its elastomeric qualities, The seal spring is preferably comprised of Silicone, EPDM rubber or materials and compositions that provide similar performance during use, or the like. The seal spring of the present invention is not limited or defined into a spring section or a seal section by its geometry. Shown is an implementation of the seal spring within a conductive female housing and connector assembly. The seal spring compresses and provides adequate spring force against a disk ferrule assembly, pressing the disk ferrule assembly, with a wire shield, against a conductive female outer housing, providing a grounding scheme for the connector assembly. The seal spring also seals against the female outer housing and a wire.

An electrical connection comprises a first conductor and a second conductor electrically connected to the first conductor. The first conductor has a first contact section with a first contact face laterally delimited by a first side face. The second conductor has a second contact section with a second contact face surrounded by a rim having a second side face. The second side face limits a contact space above the second contact face and the first contact face is arranged on the second contact face. A reservoir space is arranged between the first side face of the first contact face and the second side face of the rim, the reservoir space surrounds the first contact face and a sealing material is arranged in the reservoir space. The sealing material forms a sealing ring that seals an interface between the first contact face and the second contact face.

A connector includes a housing having a fitting part that is inserted and fitted into a counterpart fitting part, a shield shell having a shell flange part disposed opposite a wall surface of a counterpart wall body with an interval therebetween, a first watertight member between the fitting part and the counterpart fitting part, and a second watertight member that is crushed between the shell flange part and a wall surface of the counterpart wall body. The housing has a housing flange part with an outer peripheral surface thereof disposed inside an outer peripheral edge of the shell flange part and outside an inner edge of the shell flange part, and with a contact surface with an annular shape in contact with the wall surface of the counterpart wall body.

A method for manufacturing a terminal-equipped electric wire includes a step of crimping a first terminal to one end of an electric wire, a step of crimping a second terminal to the other end of the electric wire with a tubular seal member, a first waterproofing step of providing, at the one end of the electric wire, an anticorrosion member that covers an element wire bundle of the electric wire, and a second waterproofing step of providing, at the other end of the electric wire, a sealing member so as to fill gaps between conductive element wires of the element wire bundle in a tubular insulating sheath. The second waterproofing step includes a step of applying a moisture curable resin to the element wire bundle, and a step of applying a curing accelerator that accelerates curing of the moisture curable resin to the element wire bundle.

A vehicular electrical plug or connector is provided. In another aspect, an electrical connector includes a wire cable having a first end that is permanently connected to a wheeled recreational vehicle, a second end with an outlet-engageable plug thereon, and a switch allowing for a high potential or dielectric withstand test by the vehicle manufacturer in one switch condition, and then the switch allowing for normal use while detecting and/or alerting a user of an electrical ground and/or polarity problem in another switch condition. A further aspect of an electrical connector employs multiple lights on a plug, one of which alerts a user of an electrical ground and/or polarity problem, and another of which is illuminated when electricity is flowing through the plug. Another aspect of a vehicular electrical plug and method of manufacturing same, includes liquid polyurethane fed into a hole in a plug housing which then fills the otherwise open area therein to create a water-resistant seal for the plug.

An assembled waterproof and dustproof structure for charging devices, which includes a charging device casing with a first opening, a cable cover assembly including a base provided with an USB connection interface and an accommodating space, a bracket structure with a second opening, and a cover covering the USB connection interface to form a waterproof and dustproof protective cover. The first opening, the USB connection interface and the second opening are aligned with each other. The cable cover assembly, the charging device casing and the bracket structure utilize a set of snap-type components respectively disposed on the cable cover assembly and the bracket structure to form a waterproof and dust-proof snap-fit structure that closely fits in sequence from outside to inside.

The present invention provides a dummy plug that can be automatically corrected to a normal orientation, and a dummy plug structure. A dummy plug (10) is provided with a square fitting part (12) extending in the longitudinal direction. The square fitting part (12) has four corner sections (15) at diagonal positions about the axis in the longitudinal direction. Each of the four corner sections (15) has a chamfered section (17) outwardly expanding rearward and having a rearwardly tapering width dimension in the direction about the axis. Each chamfered section (17) has a ridgeline section (18) extending in the longitudinal direction and protruding outward. Each ridgeline section (18) is inclined so as to be offset further in one direction about the axis as the ridgeline section (18) extends rearward.

The present disclosure relates to a connecting element for electrical connecting two electrical modules arranged in a transmitter housing of a field device, into which transmitter housing the connecting element is insertable, the connecting element including: at least two essentially rod-shaped metal conductor elements, each with two opposing end sections, wherein the conductor elements are arranged in a defined separation relative to one another; and surrounding the conductor elements and electrically insulating them from one another, a multi-membered insulating body including two insulating body end segments of at least a first synthetic material and an insulating body intermediate segment of a second synthetic material different from the first synthetic material, wherein the first synthetic material has a modulus of elasticity greater than a modulus of elasticity of the second synthetic material.
