  • Publication number: 20180337472
    Abstract: A wire plug-in aid sleeve structure for wire connection terminal is assembled in a wire plug-in hole of the terminal. The aid sleeve includes a head section, a belly section connected with the head section and a tail section connected with the belly section. The head section, the belly section and the tail section together define a guide hole for the conductive wire to plug in. The tail section has a first side and a second side positioned on a peripheral section of the guide hole. After the conductive wire passes through the guide hole into the terminal, the metal leaf spring disposed in the terminal is facilitated to press the conductive wire toward the first side or second side.

  • Patent number: 10128583
    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: 20180323522
    Abstract: A conductive component structure of wire connection terminal is manufactured at lower cost and more securely assembled with the conductive wire. The conductive component includes a main body in the form of a plate body and a restriction body connected on the main body. The restriction body defines a mouth section and has an oblique wall connected with the mouth section. When the conductive wire is plugged into the case into contact with the conductive component, the restriction body guides the conductive wire and the rear end of the conductive wire is restricted and secured by the oblique wall. The conductive component improves the shortcomings of the conventional structure that the conductive wire is apt to deflect or swing due to external force to lead to unstable contact and insecurity and affect the electro-conductive efficiency.

  • 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.

  • Publication number: 20180182572
    Abstract: A locking/unlocking structure of switch device includes a main body and an operation button. The main body is formed with a first stop section and a second stop section. The main body defines a chamber, in which a reaction drum and a wire connection module are assembled. A first elastic unit is disposed between the reaction drum and the main body for making the reaction drum positioned in an initial assembling position, (where the wire connection module is in a closed-circuit state). The reaction drum is assembled with a restriction unit and a second elastic unit. When the reaction drum moves in response to the motion of the operation button, the second elastic unit will force the restriction unit to move from the first stop section to the second stop section so as to control the wire connection module into an open-circuit state.

  • Publication number: 20180175516
    Abstract: A wire connection terminal structure includes a terminal main body and a stopper member. One end of the terminal main body is formed with a connection section. Two support legs extend from the connection section for securely connecting with a preset circuit board. The connection section defines a socket. An elastic abutment plate obliquely extends from the connection section between the two support legs. A locating section is disposed at one end of each support leg. The stopper member is securely connected to the support legs via the locating sections. A stop face is formed on one side of one end of the stopper member proximal to the connection section and positioned in the moving path of the elastic abutment plate when elastically deformed. After the elastic abutment plate is forced, the deformation amount of the elastic abutment plate is restricted by the stop face.
