  • Patent number: 11948820
    Abstract: The present invention provides a latching guide structure arranged inside a door of semiconductor carrier. The latching guide structure comprises an upper latching part, a lower latching part, at least one elastic unit and a driver. Moreover, a first guiding portion of the upper latching part is matched with a second guiding portion of the lower latching part, therefore to define the installation space for the at least one elastic unit. On the other hand, the driver simultaneously actuates an upper actuating unit of the first guiding portion and a lower actuating unit of the second guiding portion to linearly move in reverse direction therebetween. The range of the linear motion of the upper actuating unit and the lower actuating unit represents the compression or extension of the at least one elastic unit, determining to control the open/close status of the upper latching part and the lower latching part.

  • Patent number: 11488771
    Abstract: An adapter is provided and having a circuit board, primary components and secondary components installed on the circuit board, a shielding plate disposed between the primary components and the secondary components, and a transformer installed on the circuit board. The transformer has a bobbin, an iron core set assembled with the bobbin, at least one movable pin, at least one first winding, and at least one second winding. The movable pin is able to be positioned at an upper position for allowing the iron core set to be assembled with the bobbin or for allowing the first winding and the second winding to be wound onto the winding portion, and the movable pin is able to be positioned at a lower position when the transformer is installed onto the circuit board. Thereby, the adapter can be assembled in an automated process with improved assembly efficiency and high production yields.

  • Publication number: 20220199306
    Abstract: A transformer includes a bobbin. The bobbin includes a main body, a connection member, and a terminal base. The main body is wound by a coil. Two sides of the connection member are respectively connected to the main body and the terminal base. A plurality of connection terminals of the coil extend to the terminal base through a wire trough of the main body and are connected to pins of the terminal base. The connection member is cut off by automated machining, and the terminal base is mounted on a surface of a housing of the transformer, and no pin is disposed on the housing. Hence, the overall size of the transformer is effectively reduced.

  • Publication number: 20190035526
    Abstract: A transformer includes a bobbin, a connection pin, a movable pin, a first and a second winding. The bobbin has two side walls between which a winding portion is arranged. A protruding plate extends from one of the side walls, a through hole is defined on the protruding plate, and the connection pin is arranged on the other side wall. The movable pin with a first and second latch portion is inserted in the through hole, the second latch portion is positioned in the through hole, and the first latch portion is arranged away from the protruding plate. The first winding is arranged on the winding portion and connected with the connection pin. The second winding is arranged on the winding portion and connected with the movable pin. Thereby, the transformer could be assembled in an automatic process, with low labor costs, improved assembly efficiency and high production yields.

  • Patent number: 8370865
    Abstract: A sensing device including a base, a pillar, an arm, a sensing element and a driving module is provided. The base has a supporting surface suitable for supporting the object. The pillar is disposed on the supporting surface. The arm has two ends and a pivot portion between the two ends. The pivot position is pivoted to the pillar along an axis substantially parallel to the supporting surface. The sensing element is disposed on the arm and located between an end and the pivot portion. The sensing element is located between the base and the object. The driving module is disposed between the arm and the base. The driving module drives the arm to pivot relatively to the pillar along the axis, and the sensing element moves toward or away from the object as the arm is pivoted.
