Abstract: A loop antenna is disclosed which can prevent the occurrence of variance in the loop length of the installed loop antenna element, and a method for manufacturing the loop antenna. The loop antenna comprises electrical wires constituting the antenna element and a housing that holds the electrical wires. Furthermore, the housing is formed with first guide grooves that guide the first end portions of the electrical wires and that have wall surfaces against which the tip ends on the side of the first end portions of the electrical wires abut, and second guide grooves that guide the second end portions of the electrical wires and that have wall surfaces against which the tip ends on the side of the second end portions of the electrical wires abut. Moreover, crimp parts with which the end portions of the electrical wires are connected by crimping are provided inside the respective guide grooves.

Abstract: The invention provides a contact and an electrical connector which are used to electrically connect a conductor pattern formed on a circuit board and a component to be connected that is positioned to face the circuit board, and in which the amount of displacement of the contact protruding part is large, while having a low height. The contact has a soldering part which is soldered to a conductor pattern formed on a circuit board, a spring arm which extends from the soldering part and which has a contact protruding part for contacting a component to be connected that is positioned to face the circuit board, and preload application parts which extend from the soldering part and contact the spring arm so that a preload is applied to the spring arm. The preload application parts are provided toward the fixed end of the spring arm relative to the contact protruding part.

Abstract: A card connector has a housing with contacts. A cover is mounted to the housing and has a card insertion slot that receives a card. The card has a contact portion corresponding to the contacts of the housing. A locking member locks the cover to the housing. The locking member is slideably mounted on the housing and has a cam surface that engages an end of the card. The locking member pushes the card adjacent to the contacts so that the contact portion slides across the contacts of the housing to wipe contaminants from a surface of the contact portion and the contacts to improve an electrical connection there between.
