Abstract

The utility model relates to a welding contact device used in the field of metal welding. The utility model is composed of an insulated handle, a conductive core, springs, an annular permanent magnet, movable contacts, etc. A conductive part is composed of the conductive core and the movable contacts; the conductive core, the movable contacts and springs are all positioned in the center of the annular permanent magnet; a connecting part is fixedly connected with an insulated handle by screws. The utility model has the advantages of novel structural design and high safety, and can effectively solve the problems, such as the contact between thread ends of a welding cable and a weldment surface is not stable during the process of welding operation, etc.

Description

Permanent magnetism is inhaled the tentacle handle

The utility model relates to a kind of welding contact device that is used for the metal solder field.

Arc welder uses quite general at numerous areas such as the construction of machine-building, shipbuilding, metallic conduit, tun and repair weldings, when using electric welding machine that object is carried out weld job, conventional method is earlier welding cable the end of a thread to be pressed in or to put to be welded on the weldment, carries out operation then.But be easily to cause problems such as loose contact, bad placement with the method.The loose contact meeting produces spark influences the weldment surface aesthetic, also can cause fire or cause electric shock accidents; The loose contact meeting causes welding current too small, influences weldquality, and loose contact causes cable overheated.Some user adds the attaching parts of putting a soldering turret or similar take-up clip one class on welding cable the end of a thread now, but they only are applicable to the welding of light sheet or primary structural component, so still there is certain limitation.

The purpose of this utility model provides a kind of welding cable the end of a thread and weldment loose contact of occurring in the welding process can effectively avoided simple in structure, esy to use, safe and reliable, and the permanent magnetism of problems such as bad placement is inhaled the tentacle handle.

The following realization of the technical solution of the utility model: it is by insulated handle that permanent magnetism is inhaled the tentacle handle, conductive core, spring, annular permanent magnet, movable contact, connector, the insulating cement lid, the insulation film, screw and fastening jackscrew are formed, conductive core and movable contact are formed conductive component jointly, the conductive core upper end is provided with through wires hole, conductive core, movable contact and spring all are positioned at the center of annular permanent magnet, connector is connected and fixed by screw and insulated handle, spring is between movable contact and connector round bottom face, the front end of insulated handle is provided with the insulation film, and the part below insulated handle also adds and is equipped with insulating cement lid.

Characteristics of the present utility model: simple in structure, easy to use, safe and reliable, can effectively solve the welding cable the end of a thread that occurs in the weld job process contacts unreal and bad placement with the weldment surface problem, avoided the cable that occurs in the welding process overheated, electric current is too small and produce the phenomenon of spark, has improved operating efficiency, guaranteed weldquality, and safe and reliable.

Accompanying drawing 1, permanent magnetism are inhaled tentacle handle structure schematic diagram.

Among the figure: 1 insulating cement lid, 2 connectors, 3 insulation films, 4 screws, 5 fastening jackscrews, 6 through wires holes, 7 insulated handles, 8 conductive core, 9 springs, 10 annular permanent magnets, 11 movable contacts.

Permanent magnetism is inhaled the tentacle handle as shown in drawings, it is the tie that adopts annular permanent magnet 10 to be connected with weldment as cable, the magnetic force of permanent magnet 10 can firmly be adsorbed on the weldment surface to the conductive component that has cable, because better it can not produce spark with the welded part contact-making surface in the magnet insulation, conductive component is made up of conductive core 8 and movable contact 11, conductive core upper end is provided with through wires hole 6 naked copper the end of a thread of cable line end is penetrated in this hole by the hollow of insulated handle 7, fastening jackscrew 5 being tightened just can good conductive again, spring 9 is between the round bottom face of movable contact 11 and connector 2, it can be pressed on the weldment surface with movable contact 11, it promotes the absorption affinity of the active force on 11 pairs of weldment surfaces of movable contact less than 10 pairs of weldment surfaces of permanent magnet, utilize these two active forces that movable contact 11 is contacted with weldment well, the appearance of the problems that can prevent loose contact and produce, it is reasonable that this inhales the tentacle handle structure, easy to use, safe and reliable, solved the welding cable the end of a thread in the welding process and the loose contact and the placement problem on weldment surface.

Claims

1, a kind of permanent magnetism is inhaled the tentacle handle, it is characterized in that: it is by insulated handle, conductive core, spring, annular permanent magnet, movable contact, connector, the insulating cement lid, the insulation film, screw and fastening jackscrew are formed, conductive core and movable contact are formed conductive component jointly, the conductive core upper end is provided with through wires hole, conductive core, movable contact and spring all are positioned at the center of annular permanent magnet, connector is connected and fixed by screw and insulated handle, spring is between movable contact and connector round bottom face, the front end of insulated handle is provided with the insulation film, and the part below insulated handle also adds and is equipped with insulating cement lid.
