  • Patent number: 10297930
    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.

  • Patent number: 10020136
    Abstract: A switch wire connection device has a simplified structure and is easy to operate with enhanced stability of operation. The switch wire connection device includes a conductive component mounted in an insulation case, a switch pushbutton assembled with the conductive component and an electrical contact. The electrical contact has a restriction unit and a contact plate connected with the restriction unit. By means of operating the pushbutton, the conductive component is driven to selectively electrically contact or separate from the contact plate. The restriction unit defines a space, in which a metal leaf spring is assembled. The wiring circuit or conductive wire of a machine or equipment can be easily directly plugged into the space of the restriction unit and held by the metal leaf spring. The metal leaf spring is prevented from deflecting in the operation process.

The restriction unit is divided into a first space and a second space, in which a first leg section and a second leg section of a metal leaf spring are respectively assembled. The wiring circuits or conductive wires can be easily directly plugged into the first and second spaces of the restriction unit and held by the first and second leg sections.

  • Patent number: 9899751
    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: 9735515
    Abstract: An elastic-clip junction box structure has multidirectional wire insertion effect and holds the wires quickly. The junction box structure includes a case body and at least one conductive clip disposed in the case body. The case body is formed with a first-direction wire socket and a second-direction wire socket with different insertion directions. The conductive clip has a first-direction clip mouth in communication with the first-direction wire socket and a second-direction clip mouth in communication with the second-direction wire socket. In use, the wire can be selectively inserted into the first-direction wire socket or the second-direction wire socket. Alternatively, wires can be respectively inserted into both the first-direction wire socket and second-direction wire socket.
