Abstract
The utility model provides a novel magnetic core, includes a cylinder portion, and locate cylinder portion both ends and with the cylinder integrated into one piece's of portion connecting portion, the section of magnetic core is " worker " style of calligraphy, and the symmetry is equipped with two pinholes that supply stitchs to slide in on one of them connecting portion, the pinhole is the horn type pinhole, including the straight hole that is located the lower extreme, the upper shed that is located the upper end to and the connection upper shed just guides the stitch to slide in the guide part in the straight hole with the straight hole. The utility model discloses be convenient for improve the accuracy that the stitch inserted the pinhole, product stitch pulling force is big, the size standard.
Description
[technical field]
The utility model relates to magnetic product technical field, particularly a kind of novel magnetic core.
[background technology]
As everyone knows, inductance draws pin by installation on magnetic core and forms, and for increasing work efficiency, magnetic core product pin many employings automation pin connecting machine realizes.
At present, the design of magnetic core product drawing pin hole is straight pass pin hole, and during product orientation pin, if pin connecting machine positioning precision has error, stitch is not easy to be inserted in pin hole accurately, causes bad or card machine; In addition, it is too high that the pin hole of straight pass easily produces glue point when glue, causes finished product solder joint too high, exceed fitted position during insertion machine plate.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the novel magnetic core that a kind of structure is simple, reasonable in design.
For solving the problems of the technologies described above, the utility model have employed following technical proposals:
A kind of novel magnetic core, comprise a cylindrical portion, and be located at cylindrical portion two ends and connecting portion integrated with cylindrical portion, the section of described magnetic core is " work " font, a connecting portion is arranged with two pin holes slipped into for stitch wherein, described pin hole is trumpet type pin hole, comprises the straight hole being positioned at lower end, the upper shed being positioned at upper end, and connects upper shed and straight hole and guide stitch to slip into guide part in straight hole.
Preferably, described upper shed shape is irregular ellipse, and wherein the curvature of one end circular arc is large, and the curvature of other end circular arc is little.
Preferably, connecting portion is cylinder, and the large part of described upper shed mean curvature is near connecting portion center.
Preferably, the shape of described upper shed is circular, or oval.
Compared with prior art, in the utility model, pin hole is trumpet type pin hole, is convenient to improve the accuracy that stitch inserts pin hole, and in pin hole, encapsulating amount is many, and product stitch pulling force is large, and the problem that there will not be glue point too high, size specification.
[accompanying drawing explanation]
Below in conjunction with drawings and Examples, the utility model is described further.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation two of the utility model embodiment;
Fig. 3 is the end view of the utility model embodiment;
Fig. 4 is the vertical view of the utility model embodiment;
Fig. 5 is the vertical view of existing magnetic core.
[embodiment]
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of novel magnetic core, comprise a cylindrical portion 1, and be located at cylindrical portion 1 two ends and connecting portion 2 integrated with cylindrical portion 1, the section of described magnetic core is " work " font, and a connecting portion 2 is arranged with two pin holes 3 slipped into for stitch wherein, described pin hole 3 is trumpet type pin hole, comprise the straight hole 31 being positioned at lower end, the upper shed 32 being positioned at upper end, and connect upper shed 32 with straight hole 31 and guide stitch to slip into guide part 33 in straight hole 31.
As shown in Figure 4, described upper shed 32 shape is irregular ellipse, and wherein the curvature of one end circular arc is large, and the curvature of other end circular arc is little.Connecting portion 2 is cylinder, and the large part of described upper shed 32 mean curvature is near connecting portion 2 center.
In addition, the shape of described upper shed 32 can be circular, also can be oval.
In the present embodiment, pin hole 3 is the rounded trumpet type pin hole in irregular oval lower end for upper end, uses pin connecting machine to have good positioning after pin product, when stitch inserts product pin hole 3, is more convenient for improving the accuracy that stitch inserts pin hole 3.Cause stitch in insertion hour offset pin hole 3 central authorities as pin connecting machine location produces slight deviations, but be designed to the trumpet type pin hole that upper end is irregular ellipse due to pin hole 3, stitch also can smooth and easyly slip in pin hole, reduces bad or card machine.The utility model overcomes existing pin hole when being straight hole, and stitch is easily inserted in pin hole edge, and cause the generation of the problems such as bad or card machine, Fig. 5 is the vertical view of existing magnetic core.
In addition, use new pin technique, namely first in pin hole 3, put glue, then when stitch is inserted pin hole, in the pin hole 3 of novel magnetic core, encapsulating amount is many, product stitch pulling force is large, and can not produce that glue point is too high, insertion machine plate time exceed the problem of fitted position.
Although reference above embodiment describes the utility model in detail, but be it will be apparent to one skilled in the art that by the disclosure, when not departing from principle of the present utility model and the scope of described claim restriction, can make a variety of changes the utility model or revise.Therefore, the detailed description of disclosure embodiment is only used for explaining, instead of is used for limiting the utility model, but is defined by the subject-matter of the claims the scope of protection.
