  • Publication number: 20200295542
    Abstract: A switch seat body assembling structure includes a main body for assembling with a switch component. The main body is composed of a metal head section in the form of a thin sheet structure and a nonmetal belly section. The main body is defined with an eccentric axis and has a shaft hole positioned on the eccentric axis. The metal head section has a first wall normal to or inclined from the eccentric axis and a second wall connected with the first wall and parallel to or inclined from the eccentric axis. The first and second walls together define a space. The nonmetal belly section fills the space to connect with entire sections of the first and second walls as an integrated body. The switch seat body assembling structure improves the problems that the processing and manufacturing processes are time-consuming and troublesome and the material cost is higher.

  • Patent number: 10714278
    Abstract: A switch device structure provides an ensuring system to improve the shortcoming of the conventional switch device. The switch device structure includes a main body and an operation button assembled with the main body. The main body defines a chamber in which a base seat is assembled. An operation body and a wire connection module are disposed on the base seat. The base seat is formed with a cavity in which an elastic unit is mounted. The elastic unit includes a fixed section and a free section. In response to the move of the operation body and with the fixed section serving as a fulcrum, the free section of the elastic unit can push a second contact of the wire connection module into contact with a first contact to close the circuit or away from the first contact to open the circuit.

  • Publication number: 20200220284
    Abstract: The middle section and the tail section are mounted in a wire inlet of a terminal device. The aid sleeve is formed with an internal guide hole. A wire collection section is disposed on one side of the head section distal from the middle section. A recessed guide channel is disposed on one side of the wire collection section proximal to the guide hole. The recessed guide channel includes two lateral outer arched channels with larger curvature radius. The two lateral outer arched channels gradually extend toward a middle bottom face to form an inner arched channel with smaller curvature radius. The recessed guide channel can gradually bind the forked conductor end section of a multi-strand conductive wire, whereby the wire can be quickly plugged into the guide hole.

  • Patent number: 10686262
    Abstract: A conductive component structure of electrical wire connection device is more securely assembled with the conductive wire to enhance the electro-conduction performance. The conductive component includes a main body in the form of a plate body, a restriction body connected on the main body and an aid unit (or elastic unit) assembled with the restriction body. The restriction body has a base section, a first arm and a second arm connected with the base section and free sections connected with the first and second arms. The aid unit (or elastic unit) provides greater elastic holding action force for the restriction body. When the conductive wire is plugged into the case into contact with the conductive component, the rear end of the conductive wire is at least securely pressed between the first and second arms of the restriction body without deflecting or swinging due to external force.

  • Patent number: 10651571
    Abstract: A metal leaf spring protection structure of electrical connection terminal includes a main body having a base section defined with a first end and a second end. The first end is connected with a first section and a locating section. The second end is connected with a bight section and a second section. The locating section has a head section and a tail section. The tail section extends to a position of the bight section to form a hook-like structure for providing an elastic action force and a support system. The locating section is positioned in the reciprocally moving path of the second section to set up a moving end point of the second section to improve the shortcomings of the conventional metal leaf spring that when plugging in the conductive wire, the metal leaf spring is over-bent to affect the pressing and securing effect.

  • Publication number: 20200127413
    Abstract: A protection sheath structure for switch wire connection device provides dustproof and waterproof effects and enhances the assembling security between the switch wire connection device and the conductive wire. The protection sheath has the form of a cylindrical body including a head section having a mouth section, a belly section connected with the head section and a tail section connected with the belly section. The head section and the belly section together define a chamber for assembling with the switch wire connection device. The tail section defines a guide hole permitting the conductive wire to plug into the protection sheath. Multiple annular ribs are disposed on a circumference of the tail section to enhance the structural strength of the protection sheath (or the tail section), whereby the tail section is able to bear external force produced in wiring operation of the conductive wire.

  • Patent number: 10622168
    Abstract: A locking structure of switch device includes a connection seat formed with a main body assembling hole. An arm protrudes from the connection seat. A restriction section is formed on the arm. A shift body is assembled on the connection seat and movable between a first position and a second position. The shift body has a shift section aligned with the arm in the second position. A lever member is disposed on the shift section. Two ends of the lever member are respectively formed with a ridge section and a push/press section. When the shift body moves from the first position to the second position, the ridge section passes over the restriction section into a locked state. When pressing the push/press section, the ridge section is driven by way of leverage to backward pass over the restriction section into an unlocked state.

  • Patent number: 10566149
    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: 20190386409
    Abstract: A modularized structure of switch wire connection device includes an assembling support and a wire connection module. The assembling support has a first side and a second side. The first and/or the second sides are formed with assembling sections for assembling with the wire connection module. The wire connection module includes a first wire connection module and/or a second wire connection module each having a case. The case defines a chamber for receiving and enclosing electrical contact components including conductive members. The case is formed with a mounting section for connecting with the assembling section of the assembling support. Accordingly, the wire connection module is detachably mounted on the assembling support as an integrated form.
