A coaxial cable with a terminal is formed by attaching the terminal to an end of the coaxial cable. A braided conductor at the end of the coaxial cable 1 is folded and covers the insulating sheath. A sleeve covers the braided conductor covering the insulating sheath. All around the sleeve is pressed equally. The terminal is attached to the sleeve.

Inwardly-directed projecting portions (2, 3) are formed in a bent manner respectively at distal ends of a pair of clamping piece portions (4, 5) which are continuous with each other, and form a wire connection portion (7) of a terminal (1). A conductor portion (9) of a wire (8) is located on the inner sides of the pair of clamping piece portions (4, 5), and the pair of clamping piece portions are pressed over an entire periphery into a circular shape, and are extended in a peripheral direction, thereby causing projecting extension portions (2′, 3′), including the projecting portions (2, 3), to bite into the conductor portion. Before the pressing operation, the pair of clamping piece portions (4, 5) may be provisionally pressed to be curved, thereby causing distal ends of the projecting portions (2, 3) to bite slightly into an outer peripheral surface of the conductor portion (9).

An intermediate portion of an insulating sheath of a coaxial cable is removed, and a first insulating sheath portion is drawn toward a second insulating sheath portion, so that a braid is projected into an annular shape outwardly from an interval between opposed ends of the first and second insulating sheath portions to form an annular projecting braid portion, and this annular projecting braid portion is fixed so as to be connected to a portion (that is, a braid fixing portion) of a coaxial cable shielding terminal for connection to an end portion of the coaxial cable. This connecting and fixing operation is effected by press-contacting or press-clamping.

In a method of grounding a shielded wire and a structure of grounding a shielded wire, a ring portion is formed in a ring shape by leading a braided wire to or to an opposite side of an insulating outer sheath so as to be separated in an outer circumferential direction of the insulating outer sheath. With respect to an outer circumference of the insulating outer sheath, an inner circumferential cylinder is disposed at an inner circumference side of the ring portion and an outer circumferential cylinder is disposed at an outer circumference side thereof. Further, the outer circumferential cylinder and the inner circumferential cylinder are connected each other to form a sleeve fitting. With the sleeve fitting, an attached wire is connected to the ring portion, such that grounding is performed.

In a method of connecting a terminal with a wire in which a core (2) of a wire is inserted into a tubular wire connecting portion (1) of a terminal, and the wire connecting portion is crimped in a radial direction of the wire, the wire connecting portion is compressed in a radial direction of the wire and uniformly over the whole circumference. While rotating dies (7′) by using a rotary swaging machine, the wire connecting portion is compressed by the dies in a radial direction of the wire and uniformly over the whole circumference. The wire connecting portion is compressed in a radial direction of the wire and uniformly over the whole circumference, and the outer periphery of a compressed part of the wire connecting portion has a true circular section shape.

A connecting structure for a shielded wire, including a shielded wire having a core made of a conductor, a core cover for covering the core, a braid provided around the core cover for shielding, and an insulating outer cover provided around the braid for covering the core, core cover and braid; and a shield terminal having a lead wire attached at an end to a terminal metal and conductively connected at a portion between the attached end and an unattached end to the braid of the shielded wire. This structure is formed by placing the portion of the lead wire of the shield terminal on the insulating outer cover of the shielded wire, placing a resin chip on the portion of the lead wire of the shield terminal, and applying an ultrasonic vibration so as to melt and disperse the insulating outer covers of the shielded wire and the lead wire, thereby forming a shielded conductive portion in which the shield terminal and braid are conductively in contact with each other.
摘要:
With plural conductive wire materials wrapped by a connecting plate, the plural conductive materials being located between a first electrode and a second electrode of a power supply, the first electrode abutting on the conductive wire materials, the second electrode opposite to the first electrode abutting on said connecting plate, a voltage is applied between the first and the second electrode by the power supply so that the conductive wire materials are welded to the connecting plate. Thus, there is provided a method of connecting the conductive wire materials to the connecting plate which can prevent damages of the vicinity of a crimping portion due to heat and provide complete metallic coupling between the wire materials and the connecting plate with less electric power without using a third member such as metal having a low melting point.

In the covered-wire connection method and structure in which at least one of members to be conductively connected to each other is a covered wire comprising a conductive wire portion and a cover portion of resin which is coated around the outer periphery of the conductive wire portion, both of the members are overlapped with each other at connection portions thereof, the overlapped connection portions are pinched between a pair of resin chips, and then the cover portion are melted and dispersed by ultrasonic vibration while pressing the connection portions of the members from the outside of the resin chips to conductively connect both of the members to each other at the connection portions thereof. Thereafter, the pair of the resin chips are melted to be fixed to each other, so that the connection portions are sealed with the melted resin chips.
摘要:
A wire-equipped crimp terminal includes a wire, a crimp terminal and a coating agent. The wire has a conductor exposed from an insulative sheath. The crimp terminal has a crimping piece which is press-deformed to embrace the conductor. The coating agent is coated to a first part of the crimp terminal. A recess is formed at a non-coating part of the crimp terminal where the coating agent is not coated. The coating agent is cured by irradiating light or an electron beam to the first part in a state where a part of the coating agent flowing out from the first part is received in the recess.
