摘要： A housing for an electronic component has a set of walls for surrounding the component. The component is snap-fitted into the housing to retain it in the housing through snap-fit features in the housing and snap-fit features on the component. The housing can incorporate springs which, in use, bias the component into contact with the snap-fit features. If the component is a transformer, the springs can act on the transformer laminations to press the stack of laminations together while biasing the component into contact with the snap-fit features.

摘要： A bobbin for a concentrically wound transformer, preferably a signal transformer, has a core, an area between two shoulders for a primary winding and an area between two flanges for a secondary winding surrounding the primary winding. The shoulder at the end of the transformer where the entry and exit wires for the primary winding are located is formed with an angled axial slot, and with undercut regions beneath the upper surface of the shoulder. The entry and exit wires pass through this undercut region and are thus isolated from the turns of the secondary winding. One lateral edge of the slot and the corresponding lateral edge of the undercut region diverge from one another in the direction of the bobbin end. Also disclosed is a housing for an electronic component, the housing having a set of walls for surrounding the component and lugs past which the component can snap to retain the component in the housing.

摘要翻译： 用于同轴卷绕的变压器的线轴，优选地是信号变压器，具有芯，用于初级绕组的两个肩部之间的区域以及围绕初级绕组的次级绕组的两个凸缘之间的区域。 用于初级绕组的入口和出线的变压器的端部处的肩部形成有成角度的轴向槽，并且在肩部的上表面下方具有底切区域。 入口和出口导线穿过该底切区域，因此与次级绕组的匝隔离。 槽的一个侧边缘和底切区域的对应侧边缘在筒管端的方向上彼此分开。 还公开了一种用于电子部件的壳体，该壳体具有用于围绕部件和凸耳的一组壁，部件可以卡扣以将部件保持在壳体中。
