Abstract: A connector for a plug-connected electrical component, in particular, an optoelectronic transceiver, includes a package having fastening pins for fastening the package on a printed-circuit board, the fastening pins to be connected to the board in a press-fit. Preferably, the fastening pins are U-shaped and have two resilient legs able to move toward each other. Each of the two legs has external serrations, particularly, barbs. The package is a one-part package and has a clearance on a bottom side for accommodating a plug, already fastened to the board, when the package is connected to the board. The package couples the component to the board. Also provided is a method of mounting the package by first soldering the plug for the electronic component to the board and testing the plug. Then, the package is fitted onto the board accommodating the plug with the fastening pins connected to the board in a press-fit.

Abstract: The holder is suitable for detachably fixing a component in an operational end position. The holder has an upper side on which the component is moved into the end position along a mounting direction. The holder comprises an ejector that has at least one spring which exerts an elastic force on the component in the final position. The spring force acts in a direction opposite the mounting direction.

Abstract: A detachable connecting system includes a component and a mount having cooperating guides which effect a defined movement of the component in a mounting direction into a connecting position when a connection is established. An underside of the component has a locking element which engages another corresponding locking element in the connecting position. The other locking element is disposed at a free end of a resilient tongue disposed below the component. In the connecting position, an actuation region of the free end of the tongue is accessible from a front end of the component.

Abstract: A coupling device is for coupling an optical fiber to an optical transmitting or receiving unit. The coupling device can be included in a transmitting or receiving device. The coupling device to be can be one piece, formed of a nonconductive material, and, for the optical transmitting or receiving unit, can be mounted directly on a section projecting like a step or a contact-making face applied thereto. The flattened surface of the section projects like a step and has a longitudinal notch for positioning the transmitting or receiving unit.

Abstract: The plug connector extends along a main axis and at least one optical waveguide end terminates in a connector housing. Locking parts, which are preferably symmetrically placed on the narrow sides of the connector housing, each have a detent element. An actuating element can be actuated to displace the detent elements from a locking position into a release position. The direction of displacement of the actuating element extends substantially perpendicular to the main axis of the plug connector and it is different from the direction along which the detent elements move between the locking and release positions.

Abstract: A connecting system for detachably mechanically connecting an electronic component to a support is described. The connecting system has fixed rails that are configured on the longitudinal sides of the support. When the connecting system is assembled, at least two grips on each longitudinal side of the electronic component grip under the fixing rails. Each fixing rail has at least one hole allowing the grips to be introduced vertically in relation to the support, in a direction Y, with the grips advancing in direction Z. The holes are configured in such a way that the advancing grips can pass through them during assembly without leaving the support.

Abstract: A releasable mounting device includes an electronic component having terminal contact surfaces disposed in at least two rows on an outer side. Corresponding contacts of a terminal part are correspondingly disposed in two contact rows. The contacts of each contact row can be moved jointly away from the outer side by an actuating element. During a mounting operation, the contact rows of the terminal part, which are located one behind the other as seen in a mounting direction, are moved away from the outer side one after the other by the component, beginning with a front contact row. When an end mounting position is reached, the contact rows of the terminal part pass into electrical contact with the terminal contact surfaces.
