Abstract
The utility model is created provides welding improved-type SMT inductance coil, and become traditional circular components and parts into square, square components and parts can do thinner, have complied with the short and small frivolous trend of electronic devices and components, have finally realized the slimming of electronic product; The utility model is created when the surface mount operation of SMT inductance coil, its sucker can be unified to use, and both decreases equipment cost, and eliminates replacing construction again, substantially increase the operating efficiency of SMT inductance coil surface mount operation, and surface mount operation sorption fraction defective is gone to zero; Coil body and lead portion cover, increase lead-in wire tin face, made the product past have welding effect more securely, and greatly reduced the quality hidden danger of communication product.
Description
Technical field
The invention belongs to electronic product equipment field, especially relates to the improved-type SMT inductance coil of a kind of welding.
Background technology
Tradition SMT inductance coil is circular components and parts, because the curvature of traditional circular product cambered surface is different, need prepares the multiple sucker matched with circular product cambered surface curvature, both added production cost during surface mount operation, change sucker when also costing.Traditional circular components and parts can not make electronic product realize short and small frivolous development trend.Except the operating efficiency that wastes time and energy is low, in production operation, also have a small amount of surface mount operation sorption bad.Simultaneously conventional coil lead-in wire is all standing structure with adjacent windings, and when coil lead welds with pcb board, it is less tin face, welds not firm, especially there is quality hidden danger to mobile communication product.
Summary of the invention
The invention will solve above technical problem, provides a kind of welding improved-type SMT inductance coil.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: weld improved-type SMT inductance coil, comprise lead body and lead-in wire, described lead body spirally reels and forms, described lead-in wire comprises the first lead-in wire and the second lead-in wire, described first lead-in wire is connected with described lead body one end, and described first lead-in wire covers with described lead body part, described second lead-in wire is connected with the described lead body other end, and described second lead-in wire covers with described lead body part, described lead body cross section is rectangle.
Further, described first lead-in wire and described second lead-in wire skin are provided with the coat of metal.
The advantage that the invention has and good effect are: weld improved-type SMT inductance coil, become traditional circular components and parts into square, square components and parts can fry batter in a thin layer, and have complied with the short and small frivolous trend of electronic devices and components, have finally realized the slimming of electronic product; The invention is when the surface mount operation of SMT inductance coil, and its sucker can be unified to use.Both decreased equipment cost, eliminated replacing construction again, substantially increased the operating efficiency of SMT inductance coil surface mount operation, and surface mount operation sorption fraction defective is gone to zero; Coil body and pin portions cover, increase lead-in wire tin face, made the product past have welding effect more securely, and greatly reduced the quality hidden danger of communication product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the invention;
Fig. 2 is the invention mounted state schematic diagram.
In figure: 1, lead body; 2, the first lead-in wire; 3, sucker.
Embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
As shown in Figure 1, weld improved-type SMT inductance coil, comprise lead body 1 and lead-in wire, described lead body 1 spirally reels and forms, and described lead-in wire comprises the first lead-in wire 2 and the second lead-in wire, and described first lead-in wire 2 is connected with described lead body 1 one end, and described first lead-in wire 2 covers with described lead body 1 part, described second lead-in wire is connected with described lead body 1 other end, and described second lead-in wire covers with described lead body 1 part, and described lead body 1 cross section is rectangle.Described first lead-in wire 2 and described second lead-in wire skin are provided with the coat of metal.
As shown in Figure 2, weld the preferred forms of improved-type SMT inductance coil, become traditional circular components and parts into square, square components and parts can fry batter in a thin layer, and have complied with the short and small frivolous trend of electronic devices and components, have finally realized the slimming of electronic product.The invention is when the surface mount operation of SMT inductance coil, its sucker 3 can be unified to use, and both decreases equipment cost, and eliminates replacing construction again, substantially increase the operating efficiency of SMT inductance coil surface mount operation, and surface mount operation sorption fraction defective is gone to zero.Coil body 1 and lead portion cover, increase lead-in wire tin face, made the product past have welding effect more securely, and greatly reduced the quality hidden danger of communication product.Described first lead-in wire 2 and described second lead-in wire skin are provided with the coat of metal, and coat of metal material is tin, silver or tin bismuth.The coat of metal can effectively anti-oxidation.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
