A PCB terminal is provided with a rod-like base material and a plating layer covering a predetermined region of the base material. A constituent material of the base material is a copper alloy containing 20% by mass or more of zinc. The plating layer includes a first coating portion and a second coating portion. The first coating portion includes an entire peripheral layer entirely covering a region on side of a first end part, out of both end parts of the base material, in a circumferential direction of the base material. The second coating portion partially covers a region on side of a second end part, out of the both end parts of the base material, in the circumferential direction of the base material. The entire peripheral layer includes a tin-based layer and a barrier layer.

PCB terminal, connector, wiring harness with connector and board unit

The electrical contact material includes a base material, a coating layer provided on a surface of the base material, and an oxide layer provided on a surface of the coating layer. The base material contains Cu. The coating layer includes an undercoat layer, a first layer, and a second layer that are provided in that order from the base material side. The undercoat layer contains Ni. The first layer contains Ni, Zn, Cu, and Sn. The second layer contains Sn. The oxide layer is constituted by an oxide containing Zn, Cu, and Sn. The undercoat layer has a thickness larger than 0.5 &#x3bc;m.

Electrical contact material, terminal fitting, connector, and wire harness

Provided is an electrical contact material that can suppress an increase in contact resistance even if contact pressure with a counterpart material is small. An electrical contact material that includes a base material made of metal, a metal layer provided on a surface of the base material, and an oxide layer provided on a surface of the metal layer. The metal layer is made of metal that contains zinc, copper, and tin, the oxide layer is made of an oxide that contains zinc, copper, and tin, and beneath the oxide layer, a ratio of the atomic concentration of copper to the atomic concentration of tin is less than 1.4.

Electrical contact material, terminal fitting, connector, wire harness, and electrical contact material manufacturing method

An object of the invention is to provide a connector terminal in which an outermost layer is not susceptible to wear due to repeated sliding, an electrical wire with terminal and a terminal pair. The connector terminal includes a base material and an outermost layer provided on at least part of the base material. A constituent material of the outermost layer contains 98 mass % or more of Ag, and a Vickers hardness of the outermost layer with a measuring load of 0.1 N is from 115 HV to 160 HV inclusive.

Connector terminal, electrical wire with terminal, and terminal pair

It is aimed to provide a press-fit terminal connection structure in which a board connecting portion of a press-fit terminal is press-fit into a through hole provided in a printed circuit board and which can combine the suppression of scraping of a surface layer and a reduction of a necessary load when the press-fit terminal is inserted into and withdrawn from the through hole and an improvement of a holding force for keeping the press-fit terminal inserted in the through hole. In the press-fit terminal connection structure, the press-fit terminal includes, at least on a surface of the contact point portion, an alloy containing layer mainly containing tin and palladium, and the through hole includes a tin layer on an outermost surface of an inner peripheral surface including at least the contact point portion.

Press-fit terminal connection structure having types of alloy layer

Provided are an aluminum-based terminal fitting in which a Sn layer has high peel resistance, and a terminal connecting structure of an electric wire provided with the terminal fitting. The aluminum-based terminal fitting includes a wire barrel portion () for connection to a conductor () constituted by aluminum or an aluminum alloy and provided in an electric wire (), and a fitting portion (female fitting portion () or male fitting portion ()) provided to extend from the wire barrel portion () and electrically connected to a separate terminal fitting. A Sn layer formed directly on a base material constituting the terminal fitting is provided on the contact region in the fitting portion.

Aluminum-based terminal fitting

An object is to obtain a stable electric connection resistance under a mild crimping condition. The present invention is a terminal connectorthat includes a crimp portionto be crimped to an electric wire. The crimp portionincludes a base material, an aluminum layer or an aluminum alloy layer a surface on the base material, and a hard layer on a surface of the aluminum layer or the aluminum alloy layer. The hard layer is harder than the base material. The present invention may be an electric wire with a terminal connectorthat includes the above terminal connectorand a covered electric wirethat includes a core wiremade of aluminum or aluminum alloy. The crimp portionof the terminal connectoris crimped to the core wire
