Abstract: A joint connector capable of mutually short-circuiting wires reliably without an increase in the number of components and size thereof. The joint connector (JC) comprises a joint terminal for short-circuiting and a connector housing. The joint terminal includes a plurality of electric contact portions and a short-circuiting portion connecting the electric contact portions. The connector housing has a bottom wall and other walls surrounding a terminal insertion space into which each of the wire-side terminal is inserted, and a lance for locking the inserted wire-side terminal. The lance adapted to be deflected so as to project outwardly from the bottom wall, until the wire-side terminal reaches a proper insertion depth position, to be retracted from the wire-side terminal, and elastically return into the bottom wall, when the wire-side terminal reaches the position. The deflection of the lance allows the insertion of the wire-side terminal to be checked.

Abstract: A wire harness has a joint connector having a joint terminal and a connector housing. The joint terminal has a short-circuit section and a plurality of electrical contact portions aligned in a direction substantially orthogonal to an axial direction of wires. The connector housing has an external wall surrounding terminal chambers and exposed to the outside; and a plurality of terminal locking tabs formed integrally with the external wall, the terminal locking tabs locking wire terminals. Each of the terminal locking tabs has a shape deflectable between an engaging position that locks each wire terminal and a disengaging position. The joint connector is fixed to the peripheral surface of a wire harness main body while the outer surface of the external wall of the connector housing faces and contacts the peripheral surface of the wire harness main body, the connector housing being provided with the terminal locking tabs.

Abstract: An electrical connector receptacle having a simple connector housing structure, a secure grounding connection of a metal shell to ground, and excellent durability, includes a connector housing having a pair of locking sections with nut-storing-sections formed therein, nuts stored in the nut-storing-sections, and a metal shell covering the connector housing. The nut-storing-section is open at an upper side, and formed in a vertically elongated, concave shape with a depth to receive the nut fully, and has a screw-insertion-hole running through the locking section across the nut-storing-section, and a shell-strip through-hole running through the locking section above the screw-insertion-hole. A retaining through-strip is formed in the shell and is inserted into the shell-strip through-hole and contacted to an upper part of the nut stored in the nut-storing-section, thereby preventing falling-off of the nut, and providing electrically conduction to the nut.

Abstract: To form a ground path to ground in a metal shell of an electrical connector plug with lock screws to have a simple structure of a connector housing having secure and durable performance, the connector plug includes an insulative connector housing having a rectangular body on which contacts are arranged, and locking sections extending out to two lateral portions of the body, metal lock screws inserted through screw holes formed in the locking sections, and a metal shell for electrically covering the connector housing. The shell covers the locking sections, through-holes for inserting the lock screws are formed in the shell in positions facing the screw holes, and a contact surface against which the relevant lock screw partially contacts is secured for electrical shielding around one side of each of the through-holes.

Abstract: To form an earth course to ground in a metal shell of an electric connector plug with lock screws to have a simple structure of a connector housing and secure and durable performance, the connector plug includes an insulative connector housing having a rectangular body on which contacts are arranged, and locking sections extending out to two lateral portions of the body, metal lock screws inserted through screw holes formed in the locking sections, and a metal shell for electrically covering the connector housing; wherein the shell covers the locking sections, and through-holes for inserting the lock screws are formed in the shell in positions facing the screw holes, and a contact surface to which the relevant lock screw partially contacts is secured for electric shield around one side of each of the through-holes.

Abstract: To provide an electric connector receptade with lock nut having a simple connector housing structure, a secure earth course of a metal shell to ground, and excellent durability, it indudes a connector housing having a pair of locking sections formed nut-storing-sections therein, nuts for locking by fitting-in stored in the nut-storing-sections, and a metal shell covering the connector housing. The nut-storing-section is opened at an upper side, and formed in a vertically elongated, concave shape with a depth to receive the nut fully, and has a screw-insertion-hole running through the locking section across the nut-storing-section, and a shell-strip through-hole running through the locking section above the screw-insertion-hole. A retaining through-strip is formed in the shell, which is inserted into the shell-strip through-hole and contacted to an upper part of the nut stored in the nut-storing-section, thereby prevents falling-off of the nut, and electrically conducts to the nut.

Abstract: A high frequency component detector and a limiter or clipper are provided in a video amplifier, detecting a high frequency component in an incoming video signal, responsive to the detection and clipping only the high frequency component in excess of a predetermined voltage.
