Tap switch lead cold pressing equipment

Abstract

The invention discloses tap switch lead cold pressing equipment. The tap switch lead cold pressing equipment is characterized by comprising a working table, a fixed die, a movable die and a power device, wherein the fixed die is arranged on the working table; a tap switch is positioned on the fixed die; part of or all of fixed contacts of the tap switch are positioned in a positioning groove of the fixed die; the movable die corresponds to the fixed die; shape pressing heads are arranged in wiring holes, corresponding to the fixed contacts, on the movable die or/and the fixed die; the movable die is driven by the power device; after tap leads extend into the wiring holes of the fixed contacts, the power device drives the movable die so that the movable die and the fixed die are combined, the shape pressing heads press the wiring holes and the tap leads, and part of or all of the fixed contacts are connected with the leads in a cold pressing manner. The equipment is simple in structure, convenient to operate and reliable in pressing connection, working efficiency can be improved, and the tap switch lead cold pressing equipment is suitable for cold pressing connection of tubular fixed contacts and leads of various disk-shaped and strip-shaped off-circuit tap-changers.

Description

technical field [0001] The invention relates to a tap changer lead wire cold pressing equipment. Background technique [0002] At present, the connection between the tubular contact and the lead wire of the disc or strip tap changer on the market is cold crimped one by one with crimping pliers, which has low work efficiency, and when the degree of compression is grasped by human hand, the compression is tight. The degree may be inconsistent, sometimes even not pressed tightly, especially for small-sized switches with small spacing between the tubular static contacts, the crimping jaws cannot be stretched in or the jaws are too small to be damaged, or the crimping force is limited, resulting in crimping. Unreliable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tap changer lead wire cold pressing equipment which is easy to operate, reliable in crimping, and can improve work efficiency in view of the shortcomi...
