Abstract
The invention provides a magnetic connecting piece and relates to a connecting member used among steel plates in power distribution equipment. The magnetic connecting piece is formed by penetrating and hanging a left magnet and a right magnet on a centering bolt, wherein the shapes of the left magnet and the right magnet are symmetrical, the structures of the left magnet and the right magnet are same, and the polarities of the magnetic poles of the adjacent surfaces of the left magnet and the right magnet are dissimilar. The left magnet has the structural characteristics that a rod part which protrudes rightward and is sleeved into the connected plate is arranged on a substrate, the length of the protruded part of the rod part is less than or equal to the thickness of the connected plate, and a penetrating hole which is used for penetrating and hanging the centering bolt along the axial line of the rod part is arranged on the left magnet. By depending on magnetic force, the magnetic connecting piece is clamped and connected durably and reliably and can not loosen. The magnetic connecting piece is especially suitable for connection among steel plates in power equipment.
Description
Technical field
The present invention relates to the metal connecting elements, especially for the connecting elements between the steel sheet material in the controller switching equipment.
Background technology
Current, in the controller switching equipment, commonly between sheet material (steel plate) and the sheet material be connected, after operation a period of time through bolt; The unavoidable appearance becomes flexible, and when not anxious as if processing, occurs generating heat the oxidation of acceleration contact site easily; Cause loose contact, burn out equipment, influence operate as normal and production.
Summary of the invention
The purpose of this invention is to provide a kind of loosening magnetic connecting piece of Bolt Connection formula that connects reliably, can not occur.
The objective of the invention is to realize like this: a kind of magnetic connecting piece; Left magnet symmetrical by shape, that structure is identical and right magnet are worn to hang on the centering bolt and are constituted; The polarity of the adjacent surface magnetic pole of left side magnet and right magnet is different, and wherein, the structure of left magnet is: an outstanding to the right bar portion that is used to be inserted in plate piece is arranged on the substrate; The thickness of the length≤plate piece of the ledge of this bar portion has one along its bar portion axial line, as wearing the through hole of hanging the centering bolt on the left magnet.
Aforesaid substrate be shaped as circular or square or rhombus.
Be connected with existing bolt type and compare, advantage of the present invention is:
1, it is fixing to rely on magnetic force to connect, and connection is lasting reliable, can not occur becoming flexible.
This member can be repaired the gap of junction incessantly, reduces the heating phenomenon of junction.
The method for using of this strong magnetic connector: select the kicker magnet of suitable thickness and size, an amount of conductive paste is smeared in the sheet material junction after, the centre of inserting two kicker magnets get final product, as if there being stress must install bolt additional.
The present invention is widely used in emergency service and connects fast, the stressless connecting portion of power supply facilities.
Description of drawings
Fig. 1 is the front view (right magnet is symmetry with it) of left magnet;
Fig. 2 is the profile of Fig. 1 along the A-A line;
Fig. 3 is a structure chart of the present invention;
Fig. 4 is that two boards spare of the present invention connects the structure chart when using.
Embodiment
Fig. 3 illustrates; Left magnet 1 that the present invention is symmetrical by shape, structure is identical and right magnet 2 are worn and are hung over upward formation of centering bolt (being made up of screw rod 3 and nut 4); The polarity of the adjacent surface magnetic pole of left side magnet and right magnet is different, and wherein, the structure of left magnet is: an outstanding to the right 1a of bar portion that is used to be inserted in plate piece 5 is arranged on the substrate 1b; The thickness of the length≤plate piece 5 of the ledge of this bar portion has one along its bar portion axial line, as wearing the through hole 1c that hangs the centering bolt on the left magnet.Substrate 1b is shaped as circular or square or rhombus or other Any shape (generally speaking, among Fig. 3, looking the perspective plane as long as perspective plane＞bar portion left side is looked on the left side of substrate).Fig. 4 illustrates, and two boards spare (be plate piece 5 with another plate piece 6) is worn respectively on the right ledge that hangs over left magnet on the left ledge with right magnet, and the two is crimped on together under the attraction of left and right magnet.
Claims (2)
1. magnetic connecting piece; It is characterized in that: left magnet (1) symmetrical by shape, that structure is identical and right magnet (2) are worn to hang on the centering bolt and are constituted; The polarity of the adjacent surface magnetic pole of left side magnet and right magnet is different; Wherein, The structure of left side magnet is: an outstanding to the right bar portion (1a) that is used to be inserted in plate piece (5) is arranged on the substrate (1b), and the thickness of the length≤plate piece of the ledge of this bar portion (5) has one along its bar portion axial line, as wearing the through hole (1c) of hanging the centering bolt on the left magnet.
