Abstract
The utility model discloses a power plug, consisting of a plug noumenon, a power supply cord, a plurality of pins, wherein one end of each pin is bared to insert into a jacket of a socket, while the other end of each pin is provided with a blocking boss, each pin is covered with an insulating sleeve, wherein one end of the insulating sleeve is bared while the other end is encapsulated in the plug noumenon, the insulating sleeve is also provided with a blocking hole with matching shape and size with the blocking boss on the pin, and the blocking boss is blocked in the blocking hole. Therefore, the utility model not only reserves that prior product uses the insulating sleeve to fill the gap between the pin and the insulating upper cover of the jack on the socket, thereby having the advantages of good insulation capability and good security; as the utility model adopts the fixed mode that the insulating sleeve is blocked on the pin, so compared with prior product, the connection of the insulation sleeve is firmer, thereby the plug has the advantages of safe and convenient use, long service life, etc.
Description
Technical field
The utility model relates to a kind of power supply connecting device, especially a kind of attaching plug.
Technical background
Attaching plug is widely used in life as a kind of articles for daily use.Therefore its safety in utilization also more and more causes people's attention.Attaching plug commonly used now generally is that the internal diameter of the jack of socket is provided with chamfering greater than the external diameter of pin and the insulation loam cake of jack owing to can be inserted into smoothly in the jack of socket for the ease of pin.But this structure has also been brought potential safety hazard.Because the insulation loam cake place at jack exists certain slit between the inwall of pin and jack, in the plug process of plug, be easy to bring impurity into from the slit, cause short circuit, more dangerous is, child might extend into finger in the slit, and the danger of electric shock is arranged.In order to address these problems, now corresponding product occurs, and as a kind of existing attaching plug, it is pressed into an insulating case in the pin and the header body connection of plug; Another existing attaching plug is perhaps also arranged, and it is to put an insulating case on pin, and the back side of insulating case sticks on the side of header body.All be to make on the pin external diameter at cover insulating case place equal the internal diameter of insulation upper cover part on the jack in this dual mode, thereby fill the slit between the insulation loam cake of jack on pin and the socket with insulating case.But because insulating case is to adopt the mode that is pressed into or pastes to fix, service time is of a specified duration, and insulating case comes off easily, has so just influenced the insulation effect of insulating case, has also brought the inconvenience of using.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, good insulating, particularly is connected firmly, the attaching plug of safety durable.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of attaching plug, comprise header body and a plurality of pin, one end of described pin all is encapsulated in the header body, their other end is exposed, be provided with the screens boss on described each pin, also be with insulating case on described each pin, one end of described insulating case is exposed, its other end is encapsulated in the header body, also have the screens hole that the screens boss on shape and size and the pin is complementary on the described insulating case, described screens boss snaps in the screens hole.
Described screens boss can be a square sloped surface boss.
Described screens hole can be square.
The part in the part of the band screens boss of described pin and the band screens hole of insulating case all can be encapsulated in the header body.
It is flat-shaped that described pin can be.
Described insulating case can be a hollow flat-shaped oblong shaped cartridge, and it is encapsulated in the lip limit that can be provided with a protrusion on the bottom surface of the part in the header body, can be provided with chamfering on the port of its exposed part.
Owing to fill slit between pin and the jack inwall being with insulating case on the pin, thereby increased security of products, again owing on pin, set up the screens boss, thereby can effectively prevent the caducous in use phenomenon of insulating case, therefore the utility model had both kept the characteristics of the good insulation preformance of existing product, have more be connected firmly, safe and convenient to use, and advantage such as long service life.

Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model attaching plug is described further.
With reference to the accompanying drawings, the utility model attaching plug is made of the metal pin 1 of header body 3, power line 4, two insulating cases 2 and two flats, the terminals 6 of described pin 1 connect power line 4 respectively, and be encapsulated in the header body 1, the other end of pin 1 is all exposed to connect power supply so that be encapsulated in the corresponding jack of socket.
Being encapsulated on the part in the header body 3 of described each pin 1, and be provided with screens boss 5 near pin 1 and header body 3 joints.Also be with insulating case 2 on described each pin 1, an end of described insulating case 2 is exposed, and its other end is encapsulated in the header body 3, also has the screens hole 7 that the screens boss 5 on a shape and the pin 1 is complementary on it, and described screens boss 5 snaps in the screens hole 7.Described insulating case 2 adopts the material of resinae to make.
As can be seen, described screens boss 5 is a square sloped surface boss from the upward view of the front view of accompanying drawing 2 pins and accompanying drawing 3 pins.As can be seen, described screens hole 7 is a square through hole from the upward view of the left view of the front view of accompanying drawing 4 insulating cases 2, accompanying drawing 5 insulating cases 2 and accompanying drawing 6 insulating cases 2.Adopt this shape, its objective is to make screens boss 5 and screens hole 7 be plane contact, can increase the card power between them like this, make its direction fixing easily, thereby compare other shapes easier card jail and difficult displacement.
From the upward view of the left view of the front view of accompanying drawing 4 insulating cases 2, accompanying drawing 5 insulating cases 2 and accompanying drawing 6 insulating cases 2 as can be seen, described insulating case 2 is a hollow flat-shaped oblong shaped cartridge, the bottom surface of one end in its band screens hole 7 is provided with the lip limit 9 of a protrusion, and the port of the other end of described insulating case 2 is provided with chamfering 8.
When making, insulating case 2 is inserted in and blocks the jail on pin 1, power line 4 is riveted on the terminals 6 of pin 1, then along beginning to make header body 3 near the lip limit 9 of insulating case 2, thereby finish the attaching plug that a tape insulation overlaps with PVC material injecting glue.And firm header body 3 can be blocked in the lip limit 9 of protruding.Insulating case 2 is stuck on the pin 1, also can avoid in the injecting glue process causing insulating case 2 displacements because of the ejaculation pressure of PVC glue.
In use, when pin 1 was inserted in the jack on the socket, the exposed part of insulating case 2 also had been inserted in the jack.The setting of chamfering 8 also is in order to guarantee that insulating case 2 can be inserted in the jack smoothly.The internal diameter at loam cake place is identical owing to insulate on the external diameter that design the time makes cover insulating case 2 places on the pin 1 and the jack of standard socket, and therefore, insulating case 2 has just been filled the slit between the insulation loam cake of pin 1 and jack.Can prevent that so not only impurity from falling into the slit and causing short circuit, can stop more that staff touches electrode and the electric shock accidents that causes.And because the setting in screens boss 5 and screens hole 7 is stuck on the pin 1 insulating case 2, therefore, even service time is long, insulating case 2 can not come off yet.
The shape of pin 1 described in the utility model and insulating case 2 and quantity can be done corresponding conversion according to actual needs.
