  • Publication number: 20170365939
    Abstract: An electrical contact limiter structure of wire connection terminal has a simplified structure and is easy to operate to enhance the stability of the operation and motion of a metal leaf spring. The wire connection terminal includes conductive components mounted in the insulation case and electrical contact assembled with the conductive components. The electrical contact has a limiter for receiving the metal leaf spring and restricting moving path thereof. The limiter is partitioned into at least one space. A limitation mechanism is assembled with the limiter. The metal leaf spring is mounted in the space. The wiring circuits or conductive wires coming from an apparatus can be easily directly plugged into the space of the limiter to insert with the metal leaf spring. The limiter and the limitation mechanism cooperatively prevent the metal leaf spring from being deflected and over-bent and damaged in operation.

  • Publication number: 20170331201
    Abstract: A wire connection terminal device includes a main body and a pressing/moving unit assembled with the main body. The pressing/moving unit has a shafted section, a cam section connected with the shafted section and a force application section formed on the cam section and a press section formed on the cam section. The cam section can freely rotate or swing within a chamber defined by the main body. A metal leaf spring is disposed in the chamber of the main body for pressing and electrically connecting with a conductive wire. The metal leaf spring is responsive to the motion of the pressing/moving unit to release the conductive wire. The wire connection terminal device improves the shortcomings of the conventional structure that the volume of the case and the operational space are larger and the motional travel is longer.

  • Publication number: 20170264027
    Abstract: An electrical connector limiter structure of wire connection terminal is easily operable to enhance the stability of the operation and motion of metal leaf springs. The wire connection terminal includes conductive components mounted in the insulation case and electrical connector assembled with the conductive components. The electrical connector has a limiter for receiving the metal leaf springs and restricting moving path thereof. The limiter is partitioned to define a first space and a second space with fully closed peripheries, in which the metal leaf springs are mounted. The wiring circuits or conductive wires coming from an apparatus can be easily directly plugged into the first and second spaces of the limiter to insert with the metal leaf springs. The limiter serves to prevent the metal leaf springs from deflecting in operation.

  • Patent number: 9761384
    Abstract: A shift assembly structure of switch device includes a connection seat formed with an assembling hole for rotatably connecting with a main body. A latch section is disposed on the bottom of the connection seat for latching and assembling with a wire-connection module. The connection seat has an arm protruding from the connection seat and an (elastic) restriction section formed on the arm. A shift body is assembled in the connection seat. The shift body is formed with a ridge section and a push/press section. When the shift body is moved from a first position to a second position, the ridge section is permitted to directly pass through the restriction section into a locked state. After the push/press section pushes the restriction section, the main body is unlocked from the connection seat, whereby the assembly of the main body and the connection seat is controllable.

  • Patent number: 9607783
    Abstract: A switch device structure includes at least one contact seat having a first end wall, a second end wall, two sidewalls, an upper section and a bottom section to together define a cavity for arranging a contact assembly. Each of the first and second end walls of the contact seat has a protruding assembling section and an oblique socket directed to the assembling section. The switch device structure includes a contact support equipped with a fixing board. The contact support is formed with latch sections detachably latched with the assembling sections. An operator can use a tool to directly pass through the oblique socket to unlatch the latch section from the assembling section to quickly install/uninstall the contact seat and the contact support. This solves the problem of the conventional switch device that it is troublesome and time-consuming to install/uninstall the contact seat and the contact support.

  • Patent number: 9525216
    Abstract: A shift member fixing structure of electrical connection terminal includes an assembly of a terminal and a shift member to improve the shortcoming of the conventional terminal that the structure is complicated and the manufacturing cost is higher. The terminal includes a main body defining a chamber and a metal leaf spring disposed in the chamber for pressing a conductive wire or releasing the conductive wire in response to the operation of the shift member. A predetermined section of the shift member is formed with an insertion section and walls defining the insertion section. A part of the wall is removed to provide elastic effect for the insertion section. The removed part is repositioned on a surface of upper section of the main body to form an interference section. After the shift member is pressed down, the interference section is assembled with the insertion section.

  • Patent number: 9466894
    Abstract: An electrical connection terminal structure includes: a main body defining a chamber; a metal leaf spring disposed in the chamber, the metal leaf spring being movable with the motion of a shift member to press a conductive wire into electrical connection or release the conductive wire; and an elastic unit mounted in the chamber. When the metal leaf spring is released from the pressing of the shift member to release the conductive wire from the pressing, the elastic unit normally makes the metal leaf spring and the shift member move toward a position where the conductive wire is released. This improves the shortcoming of the conventional electrical connection terminal that when released, the metal leaf spring is apt to interfere with the conductive wire and make it hard to extract the conductive wire out of the main body.
