Description
Technical field:
The utility model relates to the appliance component technical field, a kind of magnetic plug and socket with dust cap.
Background technology:
At present, widely used plugs and sockets is made up of spring roof pressure copper sheet, plastic box body etc. in the daily life.The plug insertion socket connection is connect electricity, and rear spring elasticity reduces, the contact pressure deficiency and use for a long time, causes plug to become flexible, come off easily and can't connect or the virtual connection sparking, and contact resistance increases, and will cause electric equipment to damage and initiation fire when serious.
Applied for formerly, number of patent application 01241964.8, the utility model patent that name is called " magnetic plug and socket " discloses a kind of two holes and porous socket.Establish a groove in the middle of its every group of jack, groove is embedded in magnet or iron plate, also is provided with groove in the middle of the contact head of plug, and groove is embedded in iron plate or magnetic sheet is corresponding with socket.The defective of its existence is: very close to each other between the magnet of plug and socket or the iron plate, and directly contact, the electrode contact surface of plug and socket is difficult to combine closely; And socket panel establishes a stopper slot, and the control plug accurately inserts socket, and its structure is complicated; The protruding contact-making surface of plug contact head contacts utmost point groove contact-making surface with socket, the two ends size is the same up and down for its internal diameter, plug plug difficulty, inconvenient operation.
Summary of the invention:
For overcoming the problem that above-mentioned plugs and sockets exists, the purpose of this utility model provides a kind of magnetic plug and socket with dust cap, and this magnetic plug and socket is pegged graft closely, can effectively prevent to come off, become flexible, and avoids the generation of virtual connection sparking situation.
For achieving the above object, the utility model adopts following technical scheme:
The magnetic plug and socket of described band dust cap has a groove between socket two jacks, a column core is arranged in the groove, and column core is set with magnetosphere outward, and the magnetosphere outside has one deck magnetic shielding cover, column core end face that one metal catch is arranged; Contact electrode is arranged in the jack, and the contact electrode top is turbination, and the contact electrode bottom has screw mandrel, is fixed on the bakelite panel seat by screw mandrel; There is the groove of fixing glue plank seat both sides in the socket box body, and the box body bottom is provided with the groove of a fixing square bar; The socket end face has the dustproof electric shock preventive over cap of slip, and dustproof electric shock preventive over cap both sides are provided with the convex edge, cooperates with the socket grooves on two sides.
The magnetic plug and socket of described band dust cap, has a groove between two contacts of its plug, also be placed with a column core in the groove, column core is set with magnetosphere outward, there is one deck magnetic shielding cover the magnetosphere outside, the column core end face has a metal catch, and column core is fixed on the bakelite plate by screw; Its contact top is truncated cone.
The magnetic plug and socket of described band dust cap, the inner surface of its dustproof electric shock preventive over cap also can be inlayed iron plate corresponding to the position of metal catch, is used for fixing over cap.
The magnetic plug and socket of described band dust cap behind this plug insertion socket, has certain clearance between the two.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
1, the utility model magnetic plug and socket, because gapped between the plug and socket, under the effect of magnetic force, contact-making surface produces pressure, so contact engaging and separating force is stable, can effectively prevent to come off, become flexible, and plugs plug easily.
2, the utlity model has the dustproof electric shock preventive over cap, can prevent to fall into the dust foreign material in the jack, avoid children's contact electrode, various decorative patterns can be drawn in the surface.
3, the protruding taper type depression that contacts the utmost point with socket of the taper type of header contact of the present utility model has increased contact-making surface, has avoided loose contact, virtual connection spark phenomenon.
4, the utlity model has magnetic shielding cover, can not influence signal transmission and around other electrical equipment normally use.
5, the utility model range of application: 380 volts of three-phase five pin, 220 volts of two-phase bipods, two-phase three-pin sockets need strengthen the metal finishing sheet to the zero line firewire jack, so that two-pin plug uses.Plug magnetic shielding cover diameter is little when radio and television, Communication Equipment use, and socket magnetic shielding cover diameter is inserted in greatly, and the centre has certain interval to come armoured magnetic field.Coaxial cable is pegged graft and can be pegged graft at two magnet rings of plug and socket screen peripheral hardware.A hole is established in wall socket magnetic absorbing mass bottom, passes fixedly magnetic absorbing mass of bakelite plate with screw.
It is that socket one end is the flexible connection of plug that this product can be used for low-voltage electrical apparatus one ends such as lamp holder and bulb, car electrics, radio and television, Communication Equipment, applied widely.
