Description

A kind of novel inductor coil mould group
Technical field
The utility model relates to inductance coil manufacturing technology field, in particular to a kind of novel inductor coil mould group.
Background technique
Inductance coil is a kind of inductor that can be used in high frequency, and structure is simple, and performance is brilliant, and wire specification is wide It is general, it is particularly suitable for inductance forming technique, integrated inductance uses special process pressure with iron powder by the coil of circular copper wire around the home One-pass molding is cast, there is the features such as resistance to high current, Low ESR, inductance before the forming, needs inductance coil point being welded in lead frame On, then die casting insulated iron powder, last clipped, bending etc. operate.In the prior art, work is in most cases needed Inductance coil is put one by one using electric iron and is welded on lead frame by people, then cut operation to lead frame, however in order to The versatility of product is improved also for production efficiency is improved, how to cast out and cuts flow chart simultaneously it is also possible that product has Ease for use is exactly the present inventor's problem to be solved.
Utility model content
In view of the deficienciess of the prior art, the main purpose of the utility model is to provide one kind directly to use at the scene Torn mode carrys out the novel inductor line for freely combination of the inductance coil needed and lead frame being selected to reduce costs Enclose mould group.
To achieve the above object, the utility model provides following technical solution: a kind of novel inductor coil mould group, including Lead frame and inductance coil, the lead frame include framework and several electrode foots, and the electrode foot includes the position limit arm of bifurcated, The inductance coil includes electric terminal, and the electric terminal is connect with position limit arm spot welding, and the obverse and reverse of the framework is equal It is provided with aluminium foil layer, is provided with easy-torn line in the two sides of each electrode foot in the framework.
Preferably, bonding connection between the aluminium foil layer and framework.
Preferably, the framework and electrode foot, which are integrally formed, is arranged.
Preferably, limiting slot is provided on the position limit arm.
The utility model has the following advantages compared with the prior art, and cuts flow chart it is characterized in that can save, It, can be directly at the scene using carrying out the free inductor wire for selecting needs in a manner of torn after lead frame and inductance coil welding The combination of circle and lead frame can save the expense that production cuts mould, reduce into especially for the product of small lot This.The mode of specific implementation is by the way that aluminium foil is arranged in the obverse and reverse of framework on the basis of existing lead frame and in electricity Easy-torn line is arranged in pole foot two sides, and the purpose that aluminium foil is arranged is to guarantee framework will not be made to be torn when being torn along easy-torn line It pulls bad, framework is formed as required, and easy to operate do not need additional jig and can carry out.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of novel inductor coil mould group of the utility model;
Fig. 2 is the portion A enlarged diagram in Fig. 1.
In figure: 1, inductance coil;2, framework;3, electrode foot;4, position limit arm;5, electric terminal;6, aluminium foil layer;7, it easily tears Line.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of novel inductor coil mould group, including lead frame and inductance coil 1, the lead frame includes frame Body 2 and several electrode foots 3, the electrode foot include the position limit arm 4 of bifurcated, and the inductance coil 1 includes electric terminal 5, institute It states electric terminal 5 to connect with 4 spot welding of position limit arm, the obverse and reverse of the framework 2 is provided with aluminium foil layer 6, in the framework 2 Easy-torn line 7 is provided in the two sides of each electrode foot 3.
A kind of 1 mould group of novel inductor coil of the utility model, cuts flow chart it is characterized in that can save, is leading It, can be directly to carry out the free inductance coil 1 for selecting needs using in a manner of torn at the scene after coil holder and inductance coil 1 weld The expense that production cuts mould can be saved, is reduced into especially for the product of small lot with the combination of lead frame This.The mode of specific implementation be by the basis of existing lead frame framework 2 obverse and reverse be arranged aluminium foil and Easy-torn line 7 is arranged in 3 two sides of electrode foot, and the purpose that aluminium foil is arranged is to guarantee that frame will not be made when being torn along easy-torn line 7 Body 2 is pulled bad by tearing, and framework 2 is formed as required, and easy to operate do not needed additional jig and can be carried out.
Preferably, bonding connection between the aluminium foil layer 6 and framework 2.Bonding connection is at low cost, and effect is good, while can be with Aluminium foil layer 6 is removed after facilitating tearing to form using low viscosity glue.
Preferably, the framework 2 is integrally formed with electrode foot 3 is arranged.
Preferably, limiting slot is provided on the position limit arm 4.The effect of limiting slot is so that position limit arm 4 and electric terminal 5 Between spot welding when it is more convenient, molding is perfect.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
