摘要： PROBLEM TO BE SOLVED: To reduce crosstalk between signal lines by adjacently incorporating a ground member into a insulator through ground contact and connecting the ground plate to the ground contact. SOLUTION: A ground plate 24 extending in an extending direction of a ground contact 23 is housed inside an insulator 21 adjacently to the ground contact 23. A ground plate contact piece 24a is formed in the ground plate 24 in such a manner as to be bent downward. Consequently, the ground plate 24 is brought at the contact piece 24a thereof into contact with the ground contact 23, so that the ground plate 24 can be connected to the ground contact 23.

摘要： PROBLEM TO BE SOLVED: To provide a connector having a simplified ZIF(zero-insertion-force) mechanism. SOLUTION: A connection shaft 16 is connected to an insulator 12 in each connector unit 10, and a cam groove 17 is formed in an insulator cover 14. The connection shaft 16 has a connection pin 16a installed to be movable along a groove part 12a. The connection shaft 16 has a groove part 16b extended in a specified direction, an operation lever 18 has a pin (protrusion) 18a inserted into this groove part 16b, and the operation lever is rotatably supported about a support point 19a at a different position from a protrusion 18a formed position. By rotating the operation lever 18 to move the connection shaft 16, the connection pin 16a moves along the groove part 16b and the cam groove 17 as the connection shaft 16 moves, so the insulator cover 14 is moved by the cam groove 17 to engage/remove the connector unit 10.

摘要： PURPOSE: To facilitate the release of a lock and improve mounting efficiency by having a built-in lock release mechanism in a connector. CONSTITUTION: A receptacle side connector 1 is equipped with a lock engaging window 7, and a plug side connector is equipped with a plug side connecter housing 2a on which a lock release slant face 8 is provided, an elastic body- made slide member 3 on which a lock engaging dowel 6 and tip slant face 3c are provided, and an extracting tab 4. In a locked state, when the protrusive portion of the slide member 3 is pushed leftward, the tip slant face 3c thereof is guided left downward along the lock release slant face 8 so that the lock engaging dowel 6 escapes from the lock engaging window 7 to fall into the plug side connector housing 2a. As the result, lock is released, and the lug 4a of the extracting tab 4 is pushed by the abutting portion 3b of the slide member 3 so that the extracting tab 4 turns counterclockwise by 90 deg. centering a fulcrum 4b. When the extracting tab 4 is pulled leftward, the plug side connector can easily be uncoupled from the receptacle side connector 1.

摘要： PROBLEM TO BE SOLVED: To provide a strip line structure and contrive for impedance matching by forming a signal contact and an earth contact adjacently, and besides varying the shape of both contacts. SOLUTION: An insulator 3 has a fixing part 3c extending outward of each of a pair of thick wall faces 3b, with the same dimension as the thickness of the insulator 3, at each of a pair of thick wall face 3b facing each other. First and second contacts 1 and 2 are incorporated in parallel alternately to one side 3d of the insulator 3. It is signal, width dimension and thickness dimension of an earth conductor, the permittivity of the dielectric between the signal and the earth conductor, etc., that the impedance of the strip line is determined. Accordingly, to contrive for the impedance matching of the strip line in a connector 9 for high-speed transmission, there is necessity to change the form and the size between the first signal contact 1 and the second earth contact 2.
