A thin-film transistor array includes an electrically insulating substrate, a plurality of thin-film transistors arranged in a matrix on the substrate, and each including a channel, a source, and a drain each comprised of an oxide-semiconductor film, a pixel electrode integrally formed with the drain, a source signal line through which a source signal is transmitted to a group of thin-film transistors, a gate signal line through which a gate signal is transmitted to a group of thin-film transistors, a source terminal formed at an end of the source signal line, and a gate terminal formed at an end of the gate signal line. The source terminal and the gate terminal are formed in the same layer as a layer in which the channel is formed. The source terminal and the gate terminal have the same electric conductivity as that of the pixel electrode.

The invention relates to a microphone assembly comprising a housing, a microphone element within the housing, a base element, contacting elements, a removable element, and connecting means. The housing is configured such that it may be opened and re-closed. The base element is positioned inside the housing and comprises one or more first electrical conductors. The base element comprises one or more first conducting surface parts connected to one or more of the first conductors. The contacting elements facilitate electrical contact between one or more of the first conductors and one or more conductors positioned outside the housing. The removable element is positioned within the housing and comprises one or more second electrically conductive surface parts. The connecting means provides an easily breakable / removable electrical connection between a first surface part and a second surface part.

In order to promote the adhesion of a crimp terminal (10) to an aluminum electric wire (100) by virtue of crimping to thereby realize an improvement in electric connecting performance, the thickness of tin plating applied to an inner surface of a conductor crimping portion (13) of the crimp terminal (10) is set to be in the range from 2.1 μm to 5.0 μm, and then, the conductor crimping portion (13) is crimped to a conductor (100a) of the aluminum electric wire (100).

An electric connector includes a male connector and a female connector, the male connector including a cylindrical main portion, and a male contact terminal formed at the main portion. The female connector includes a hole into which the main portion is fit, and a female contact terminal formed at the hole for making electrical contact with the male contact terminal when the main portion is fit into the hole. One of the male connector and the female connector includes a guide shaft axially extending in a direction in which the male connector is fit into the female connector, and the other of the male connector and the female connector includes a guide hole for allowing the guide shaft to be inserted thereinto to guide the guide shaft in the direction.

An insulation displacement contact includes a pair of insulation displacement blades and a pair of resilient contact pieces. The pair of insulation displacement blades are opposite to each other with their bases connected to each other such that there is formed, by their inner sides, a slot for receiving an insulated wire of which core wire portion is covered with an insulation. The pair of insulation displacement blades are arranged such that when the insulated wire is inserted into the slot, the insulation is cut and the core wire portion comes in press-contact with the insulation displacement blades. Each of the pair of resilient contact pieces is made of a plate member which is connected to the outer side of each insulation displacement blade, which extends toward the side opposite of the inlet of the slot up to a position exceeding the base of each insulation displacement blade, which has a contact portion for holding or nipping a mating contact at a position opposite of the slot inlet with respect to the base of each insulation displacement blade, and which has, between the connection portion connected to the outer side of each insulation displacement blade and the contact portion, a tapering portion of which width is gradually narrowed in the direction toward the contact portion.

A connector and a connecting structure of circuit boards therewith is provided, which includes: a first circuit board; a second circuit board orthogonally arranged relative to the first circuit board; a terminal having first and second contact portions for the respective first and second circuit boards; and a housing to accommodate the terminal. An engaging member for attaching the housing to the first circuit board projects from the housing, and the first contact portion projects in a same direction as the engaging member. The engaging member is longitudinally movable at an engaging portion provided on the first circuit board. The engaging member is pivotable. The housing consists of a pair of housings turnable about a hinge, and a second contact portion of the terminal is accommodated between the housings.
