Abstract
The utility model discloses a flat plug belonging to electrical connection device. Pins are arranged on the front end of the plug internal mould. And an elastic slice is arranged on one side of the pin, and the top end of the cable enters into the plug internal mould from end of the plug internal mould and is connected with the end of the pin. The outside of the internal mould is the plug external mould. The utility model has the advantages of simple structure, low cost, easy use, the utility model is reliable with good contact with the external socket, and the service life is long.
Description
Technical field
The utility model relates to a kind of electrical connection arrangement, relates in particular to a kind of flat plug.
Background technology
In the power line and other connecting line of high frequency surgical equipment and each electron-like, electric equipment, need use the flat plug, the flat plug of prior art and the contact portion of equipment are that whole piece copper pipe or the copper with protruding bullet position props up, because the corresponding adapting position with external equipment of contact point is the friction between the high-intensity five metals material, so can produce following bad result: 1, plug shell fragment position is easy to generate oxidation and the surface causes getting rusty, and makes the contact point loose contact; 2, damage the interior contact site of jack of suitable with it external equipment easily prematurely, cause expensive external equipment damage parts; 3, because plug shell fragment Flexible Reset is bad, cause the contact strength of the contact site in the jack of the suitable with it external equipment of contact point to change or non-contact-point exists, lose the conflict function so be easy to the too early plug shell fragment that makes.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of the contact with external equipment well, uses stable, reliable flat plug.
The technical scheme that its technical problem that solves the utility model adopts is: the front end at the plug internal mold is provided with pin, one side of pin is provided with shell fragment, the end of electric wire enters the plug internal mold and is connected the tail end of pin from the afterbody of plug internal mold, and the arranged outside of plug internal mold has the plug external mold.Adopt less shell fragment to replace whole piece copper pipe in the prior art, simple in structure, volume is little, cost is low, and it makes pin better with contacting of external equipment, reliable and stable during use.
In order to adapt to most in the market equipment, plug internal mold front end generally is provided with three pins.
In order to guarantee the non-oxidizability of contact point, make the shell fragment surface can not cause loose contact because of getting rusty, be coated with the protection against oxidation layer on the surface of pin and shell fragment, described protection against oxidation layer can be Gold plated Layer, silver coating or nickel coating.
In order to guarantee that the user in use inserts plug and extract the jack of adaptive with it external equipment easily, be provided with projection at the rear portion of plug external mold both sides flat horizontal surface, raised surface is provided with anti-skidding line, prevents that plug from slipping out of the hand from hand or sliding.
The beneficial effect that the utility model produces is: simple in structure, cost is low, easy to use, contact with the jack of external equipment good, reliable and stable, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of a kind of embodiment of flat plug of the present utility model;
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of flat plug shown in Figure 1.
Among the figure: 1. electric wire, 2. projection, 3. anti-skidding line, 4. plug external mold, 5. plug internal mold, 6. pin, 7. shell fragment.
Embodiment
As depicted in figs. 1 and 2, three cores in the electric wire 1 are welded on respectively on three pins 6, are not provided with shell fragment 7 on the pin 6, the tail end of pin 6 is fixed on the plug internal mold 5, plug internal mold 5 arranged outside have plug external mold 4, and plug external mold 4 generally can be shaped by injection molding way.In order to adapt to different application scenarios, also can use the pin of two pins or other number.The electric wire 1 general copper core outside of adopting coats PVC, also can adopt other electric conducting material to do core as required, adopts other insulating material to do coating layer.For intensity and the friction resistant ability that guarantees adapting position, plug inner membrance 5 can adopt nylon material (PA), match steel material (POM) or polystyrene (PS) material of high strength, high bending, also can adopt other to have the material of similarity.Plug external mold 4 can adopt the PVC material.Pin generally can adopt the phosphor-copper material, in order to guarantee the non-oxidizability of contact point, at protection against oxidation layers such as the surface gold-plating of phosphor-copper pin and shell fragment, silver-plated, nickel plating.For prevent the user in use plug from hand, slide or slip out of the hand, projection 2 can rear portion, plug external mold 4 both sides be set, on the surface of projection 2 anti-skidding line 3 is set.
Flat plug of the present utility model is inserted in the adaptive with it jack, and the elastic force by shell fragment 7 makes pin 6 closely contact with metal part in the jack, thereby reaches the effect of transmission electric energy or signal, and it contacts well, and is reliable and stable.
