Abstract
The utility model discloses a kind of air core coil inductor, it comprises enameled wire loop (1), two exits of enameled wire loop (1) form Surface Mount pad (2), described labeling pad (2) is horizontal plane with the contact-making surface of pcb board, the utility model is by the adjustment of technological design, the contact-making surface of the pad of air core coil inductor and pcb board is become to horizontal plane, or pad is become square, make pad originally contact and become face contact with the line of pcb board, increase the bonding area of inductor, welding quality and the reliability of inductor are promoted, so just can pinpoint the problems in advance, avoid rosin joint, dry joint, further improve equipment quality.
Description
Technical field
The utility model relates to a kind of air core coil inductor, belongs to inductors technique field.
Background technology
Existing air core coil inductor, the enamelled wire of employing is circular copper wire, and it is that line contacts while welding with pcb board, easily causes the failure welding (rosin joint) of product, and the dry joint, the rosin joint phenomenon that exist like this can not detect the very first time, easily make product failure.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of area that while welding, pad contacts with pcb board that increases, and increases a kind of air core coil inductor of the reliability of welding, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: plant air core coil inductor, it comprises enameled wire loop, and two exits of enameled wire loop form pad, and described pad and the contact-making surface of pcb board are horizontal plane.
Above-mentioned air core coil inductor is that described enamelled wire is enamel-cover circle line.
Compared with the prior art, the utility model is by the adjustment of technological design, the contact-making surface of the pad of air core coil inductor and pcb board is become to horizontal plane, or pad is become square, and make originally pad contact and become face contact with the line of pcb board, increase the bonding area of inductor, welding quality and the reliability of inductor are promoted, so just can pinpoint the problems in advance, avoid rosin joint, dry joint, further improve equipment quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model air core coil inductor is described in further detail.
As shown in Figure 1, the air core coil 1 that air core coil inductor is mainly coiled into by enamelled wire and the enamelled wire two ends pad (2) forming that goes between, described enamelled wire 1 is circular copper wire, forming after air core coil 1, extrusion process processing is carried out in its two ends, and making the pad 2 of the air core coil of this circular copper wire is horizontal plane with the contact-making surface of pcb board, can become face contact from original line contact like this, increase bonding area, improve soldering reliability.
Claims (2)
1. an air core coil inductor, it comprises enameled wire loop (1), two exits of enameled wire loop (1) form pad (2), it is characterized in that: described pad (2) is horizontal plane with the contact-making surface of pcb board.
2. air core coil inductor according to claim 1, is characterized in that: described enamelled wire is enamel-cover circle line.
