Abstract

An electrical connector is miniaturized and reduced in profile height, yet maintains strength and connection stability, uses elastic fixtures as a power source and provides stable fitting. When connectors are fitted with each other, a first contact of an elastic first fixture is brought to contact a second contact of a second fixture to be used as a power source. An inclined portion of a receptacle contact and an inclined portion of an insertion hole of a housing are formed roughly in the same shape to adjust support of the receptacle contact and provide stable connection. A first chamfered portion of the receptacle contact engages a recess of a plug contact to produce a clicking feeling. The first chamfered portions are positioned and brought to contact the recesses so the plug contact is held between a contact portion and an elastic portion of the receptacle contact.

Abstract

A microcontact according to the invention is less than 10 mm in length and composed of a conductive basis material, a base surface treatment layer formed thereon, and an upper surface treatment layer, and includes a contact portion, a terminal portion, and an intermediate portion formed over its entire circumference with exposed oxide surfaces of the base surface treatment layer. The exposed oxide surfaces are formed by irradiating the front and rear surfaces of the contact with laser beams at respective predetermined inclined angles to remove the upper surface treatment layer and simultaneously to oxidize the narrow base surface treatment layer exposed by the removal of the upper surface treatment layer. In this manner, the exposed oxide surfaces can be formed with a high accuracy in a simple manner for stopping solder rise at a predetermined position when the terminal portion of the microcontact is jointed to a substrate by soldering.

Abstract

This invention provides a process for producing an electronic component, which can suppress an external force-type whisker without diffusion of component atoms constituting a material (70) and a substrate layer (72) into a tin-containing material layer (74), and an electronic component produced by the process. In the production process, the material (70) is subjected to surface treatment. The production process comprises the step of providing the substrate layer (72) on the surface of the material (70) to surface treat the material (70), and the step of providing a tin-containing material layer (74) above the substrate layer (72) to surface treat the substrate layer (72). The production process further comprises the step of, before the provision of the tin-containing material layer (74), providing a barrier intermediate layer (76) for preventing the component atoms constituting the material (70) and the substrate layer (72) from being diffused into the tin-containing material layer (74) to suppress the occurrence of external force-type whiskers upon the application of external force to the surface of the tin-containing material layer (74).
