[0005]
This connector includes an insulator, a contact, and a slider.
[0006]
The insulator has a substantially frame shape, accepts a part of one connection object (for example, a ceramic substrate), and is disposed on the other connection object (for example, a fixed substrate). The insulator has a contact insertion groove and a slider insertion groove. A large number of contact insertion grooves are formed on each side constituting beam of the insulator. The slider insertion groove is formed in the upper part of each side constituting beam.
[0007]
The contact is incorporated in the contact insertion groove. The contact includes a contact portion (a retaining contact portion), a spring portion (upper and outward biasing portion), a pressed portion, and a fixed conductive leg. A contact part contacts the terminal part of one connection target object, and prevents one connection target object from coming off. The spring portion presses the contact portion against the terminal portion of one of the connection objects. The pressed part is pressed by the slider and pushes the spring part toward one of the connection objects. The fixed conductive leg is soldered to the terminal portion of the other connection object.
