Description

Free-swing lead-in type directional contact plug box

Technical Field

The utility model relates to a contact, the positioner technical field of moving, the static contact, in particular to free swing leading-in formula directional contact jack box.

Background

In the field of electrical appliances, the completion of the on-off of a circuit and the transmission of current are usually completed by the mutual contact of a movable contact and a fixed contact. Therefore, the mutual contact of the movable contact and the fixed contact is widely applied to different equipment as an opening and closing device. There are various contact modes of moving and static contacts, but the basic forms are two categories: one is the plug-in contact type; one type is a planar contact.

The insertion contact is that the moving contact contacts the static contact accurately under the action of the guiding and positioning device. The contact mode has various errors inevitably existing in the manufacturing, designing, machining and process assembly processes of equipment, and coaxiality or same planeness cannot be ensured between moving and static contacts of two or more conductors due to size errors in the contact process, so that high temperature, arc spraying and fusion welding are generated between the two conductors due to poor contact and surface heating oxidation in the contact process. Therefore, in practical design, only one error limit has to be specified during the manufacturing and assembly process of the device. As long as the error limit is not exceeded, the requirements are substantially met. For example: plug-in isolating contacts are adopted in handcart type high-voltage switch equipment at home and abroad. When the car body is pushed into the cabinet along the track, the positioning system controls whether the car is in place and locked, and in the contact process, the design requirement is that the error size of the car body is not more than 5 millimeters in the vertical, horizontal, front and back directions. However, due to many factors such as mechanical manufacturing errors, action errors of a positioning system, clearance accumulation errors and the like, the error size of the equipment is difficult to control below 5 mm, which undoubtedly brings inconvenience to good contact between a vehicle body and a cabinet body and influences the electric transmission function. From another aspect, such a handcart-type device requires interchangeability, namely: different automobile bodies should be applicable to different cabinets, and when the automobile body after the exchange pushes into the cabinet body, the same requirement does not exceed the error range that limits, and this is difficult to guarantee more.

In the prior art, the sliding of the pulley is adopted, the accuracy is far from insufficient, great deviation is easy to generate, and the service life is greatly reduced.
