Technical Field

The utility model belongs to the technical field of the dual in-line package, especially, relate to a U type does not have Pin foot through-hole paster dress device.

Background

Among the prior art, the Pin foot terminal of conventional SMD product is L foot or sea gull foot, and the major part of few foot product of trade all has the length and width height restriction simultaneously, and the product can't increase the wire winding groove, and the wire jumper takes place easily when the tin is sunk in the client side wire winding, and SMD product inner chamber is magnetic core cylinder form, and the operator wire winding overlaps slightly will lead to can't putting the heart yearn, and SMD is sharing type product, nevertheless leads to the unable sharing of total height specification superelevation behind the client side welded plate because of the difference in height often.

SUMMERY OF THE UTILITY MODEL

The utility model discloses just not enough to prior art exists provides a U type does not have Pin foot through-hole paster dress device.

In order to solve the above problems, the utility model adopts the following technical proposal:

the utility model provides a U type does not have Pin foot through-hole paster dress device, includes the body, the body is cuboid injection moulding plastic part, and body length direction one end middle part is equipped with the rectangle vallecular cavity, and rectangle vallecular cavity open end length direction bilateral symmetry is equipped with the rectangle and leads to the groove, and rectangle leads to outside one side of groove to be equipped with injection moulding's T shape post, and T shape post tip is connected perpendicularly on the body outer wall, and T shape post main aspects is located the vertical direction.

Furthermore, a plurality of groups of T-shaped columns are arranged on the body, the T-shaped columns on the same side are symmetrically arranged at two ends and the middle of the rectangular groove cavity in the length direction, and the T-shaped columns on the same side are symmetrically arranged in the middle.

Furthermore, the small end of the T-shaped column is located below the opening outer edge of the rectangular groove cavity, the large end upper opening of the T-shaped column is located above the opening outer edge of the rectangular groove cavity, the magnetic core is installed in the rectangular groove cavity, and the magnetic core is wound on the small end of the T-shaped column through the rectangular through groove.

Furthermore, the magnetic core wound with the T-shaped column is wrapped by winding and soldering tin and is wrapped by the large end of the T-shaped column.

Compared with the prior art, the utility model discloses an implement the effect as follows:

a U type does not have Pin foot through-hole paster dress device, plastic main part integral type injection moulding, the processing degree of difficulty is less, the finished product yield is high, rectangle groove cavity space is big, can put cylinder magnetic ring or square magnetic ring, increase the flexibility of product magnetic ring, magnetism wire winding is on T shape post and soldering tin, the whole T shape post of soldering tin cladding utilizes T shape post to replace the Pin foot, Pin foot mounting process has been reduced, the bad condition of Pin foot can not take place, when having reduced the processing cost, machining efficiency and product yield have been improved.

fig. 2 is a schematic view of a U-shaped device with no Pin through holes and mounted on a chip.

Detailed Description

The present invention will be described with reference to specific embodiments.

As shown in figure 1 and figure 2, a U type does not have Pin foot through-hole paster dress device, including body 10, body 10 is cuboid injection moulding plastic part, body 10 length direction one end middle part is equipped with rectangle

vallecular cavity

11, 11 open end length direction bilateral symmetry in rectangle vallecular cavity are equipped with rectangle through groove 12, rectangle through groove 12 outside one side is equipped with injection moulding's T shape post 13, T shape post 13 tip is connected perpendicularly on body 10 outer wall, and T shape post 13 main aspects is located the vertical direction.

Be equipped with multiunit T shape post 13 on the body 10, homonymy T shape post 13 symmetrical arrangement is at 11 opening length direction both ends of rectangle slot cavity and middle part, and symmetrical arrangement in the middle of the T shape post 13 of homonymy to through the size that changes body 10, satisfy the specification demand that different customers selected.

The small end of the T-shaped column 13 is positioned below the outer edge of the opening of the rectangular groove cavity 11, the upper opening of the large end of the T-shaped column 13 is positioned above the outer edge of the opening of the rectangular groove cavity 11, a magnetic core is arranged in the rectangular groove cavity 11, and the magnetic core is wound on the small end of the T-shaped column 13 through the rectangular through groove 12; the magnetic core winding of the T-shaped column 13 is wrapped by the tin soldering, the large end of the T-shaped column 13 is wrapped, and the T-shaped column 13 wrapped by the tin soldering replaces a Pin, so that the Pin mounting process is reduced, the situation of poor outside of the Pin is avoided, the production cost is reduced, and the processing efficiency and the product yield are improved.
