Definitions

  • the present invention relates to a connector used in electrical industry, particularly the terminal that may open the connecting port by using its built-in operating handle to achieve fast connection and disconnection.
  • Conductor terminals are widely used in all kinds of electrical connections.
  • most of the terminals are comprised of insulating material housing, electric conductor, line presser, and screws. And the line presser and screws are joined by thread.
  • the wire is pressed onto the electric conductor with the screw and the line presser to achieve the connection between the wire and the electric conductor.
  • This kind of wire connecting structure requires the use of screwdriver to tighten or loosen the screw to complete the connection or disconnection, which is labor consuming and inefficient.
  • screw slippage and damage to the screw notch may happen due to improper operating force, and therefore impair the repeated use of the product. Under vibrating environment, screwed connection may become loose and result in wire connection failure or connection signal interruption.
  • Other terminals may be comprised of the electric conductor and cage spring.
  • this kind of terminal features easier wire connection.
  • the cage spring needs to be mounted with the conducting strip in advance, which result in assembling inefficiency and higher labor cost.
  • screwdriver is required to open the connection port of the cage spring to insert and remove the wire.
  • the purpose of the present invention is to come up with a kind of terminal with an operating handle to achieve fast wire connection and wire withdrawal and convenient maintenance without using any additional tool.
  • a wire incoming hole has been provided on the front of the said insulating material housing and flanges at the back on four sides. Under cuts have been provided on the bottom and top flanges.
  • a current detection hole has been provided at the bottom of the insulating material housing to detect the line after wire connection.
  • a current carrier mounting guide slot has been provided inside the cavity of the said insulating material housing for fixing and controlling the current carrier.
  • a spring mounting guide slot has been provided in the cavity of the said insulating material housing for fixing and limiting the spring.
  • a guide chamfer has been provided on the top and bottom surface of the said current carrier for introducing the wire.
  • An anti-slip barb has been provided at the bottom of the said current carrier to prevent the wire from slipping.
  • a right-angle cut portion has been provided at the top of the said spring to increase the clamping force and friction of the wire.
  • a bended arc has been provided at the top of the said spring for taking the force of the handle and bringing the spring to elastic compression.
  • a round rotating axis has been provided to the said operating handle for locating the center of the rotating action of the handle.
  • a rotating limit has been provided to the said operating handle for controlling the rotating angle of the handle.
  • a square hole has been provided on the top and bottom of the said insulating cover for matching and locking with the under cut of the insulating material housing.
  • a semi-circle limiting surface has been provided inside the cavity of the said insulating cover for installing, matching, and controlling the rotation of the round rotating axis of the operating handle.
  • a limit has been provided at the top of the cavity of the said insulating cover for controlling the back-and-forth movement of the current carrier after installation.
  • a square column protruding from the bottom of the cavity of the insulating cover is used for pressing tightly against the spring after installation.
  • the angle on the insertion surface of the wire shall be smaller than 50°.
  • the terminal of the present invention doesn't require any additional tool. It may achieve the connection of both a single hard wire and multiple soft wires. For connection of single hard wire, there is no need to pull the operating handle. Simply remove the insulating material of the wire and insert into the inlet hole to complete the connection. To connect multiple soft wires, simply pull the handle till it is 90° to the horizontal direction of the incoming wire, the operating handle will automatically lock, and insert the multiple soft wire without the insulating material into the inlet hole, and pull the operating handle back to the position that is horizontal to the wire incoming direction to complete the connection. If it becomes necessary to release and disconnect the wire, pull the operating handle from horizontal direction till it is 90° to the horizontal incoming surface and pull out the wire to disconnect. Compared to traditional terminals, the present invention doesn't require any additional tools. Particularly the direct insertion of the single hard wire ensures outstanding connection efficiency, easy connection, and high effectiveness.
