摘要:
A molded lamp socket. The molded lamp socket includes a lamp base body defining a socket cavity with an opening for receiving a lamp bulb. The molded lamp socket also includes a lead extending from a first contact portion disposed in the socket cavity to a second contact portion spaced from the socket cavity. The molded lamp socket also includes a mounting body defining a plug cavity encircling the second contact portion. The mounting body is overmolded with respect to the lamp base body and less than all of the lead, the second contact portion being exposed. The lamp base body is formed from a first plastic with a first level of resistance to out-gassing and the mounting body is formed from a second plastic with a second level of resistance to out-gassing less than the first level of out-gassing.

A halogen-free flame-retardant compound and method of forming a continuous material therefrom includes compounding poly(ethylene terephthalate) (PET) with fire-retardant ingredients melamine cyanurate (MC) and melamine polyphosphate (MPP). The compound is then formed into pellets and/or extruded as a thin film or sheet, and also as a filament or yarn, including monofilaments and multifilaments.

A method and assembly for protecting a device connected to a wiring harness is disclosed. The assembly includes a protective shield having a bore for receiving the device and a positioning device. An elongated wiring harness extends from the device being protected and through the bore of the protective shield. The positioning device is formed having a band that surrounds a central space. At least one flexible, resilient finger extends radially inwardly from the band into the central space. At least one of the fingers forcibly engages the harness sleeve to maintain the positioning device and the protective shield in a predetermined protection position along the harness sleeve at least partially surrounding the device being protected.

A heat shield assembly includes shroud or housing fabricated from a heat shielding material having at least one pair of spring arms extending from side walls of the shroud for engaging a member to which the heat shield assembly is to be attached, and one or more retention tabs projecting into a longitudinal channel in position to limit longitudinal movement of the assembly relative to the member when the member is attached to the spring arms.

The subject invention provides a gasket for sealing multiple fluids and a method of forming the gasket. The gasket includes a carrier, a first elastomeric material, and a second elastomeric material different than the first elastomeric material. The first and second elastomeric materials are disposed in contact with the carrier in a flowable state such that the first and the second materials flow together to form a third elastomeric material comprising a mixture of the first and second elastomeric materials. The first and second elastomeric materials include cure systems that are compatible to ensure sufficient bonding within the third elastomeric material. Adhesive materials that are compatible with each of the first, second, and third elastomeric materials and the carrier are used to bond the elastomeric materials to the carrier.
摘要:
An improved compression load ball joint assembly consisting of a metal housing having an open end and an internal cylindrical chamber which at least partially encloses a portion of a movable stud member, a lower metal bearing, an upper metal split bearing, and a Belleville washer. The upper metal split bearing is disposed opposite the lower metal bearing to engage the movable stud member and the housing simultaneously. The upper metal split bearing is configured to slide within the housing to provide for a constant wear surface against the movable stud member. The lower metal bearing, upper metal split bearing, Belleville washer, and movable stud member are contained within the housing by a cover plate concentrically disposed about the movable stud member and secured within the open end of the housing.

A wiper arm assembly and method of construction thereof includes a mounting head and a wiper arm configured for relative rotation during assembly from a disassembled position to a shipping position, wherein the wiper arm and mounting head are locked against rotation toward the disassembled position once in the shipping position. The mounting head and wiper arm have locking surfaces configured for locked engagement with one another while in the shipping position. The locking surfaces are brought into engagement with one another by a force imparted by a spring while rotating the mounting head relative to the wiper arm from the disassembled position toward the shipping position. When in the shipping position, the locking surfaces confront each other and prevent the mounting head and the wiper arm from rotating back toward the disassembled position from the shipping position.
摘要:
A method of manufacturing a radial shaft seal assembly. The method includes the step of stretching an inner diameter of a ring-shaped polytetrafluoroethylene seal radially outward from an axis with a mandrel to a first stretched condition on a mold core element. The method also includes the step of defining a substantially enclosed mold cavity around the polytetrafluoroethylene seal stretched over the mold core element with at least one mold element. The method also includes the step of locating a rigid casing within the mold cavity spaced from the stretched polytetrafluoroethylene seal. The method also includes the step of introducing a liquefied rubber elastomer into the mold cavity. The method also includes the step of molding the liquefied rubber elastomer under heat and pressure such that the rigid casing and polytetrafluoroethylene seal in a stretched state are bonded to a solid rubber elastomer member. The method also includes the step of removing the collectively bonded polytetrafluoroethylene seal and rigid casing and rubber elastomer member from the mold core element without stretching the inner diameter of the polytetrafluoroethylene seal beyond the first stretched condition.
