the mark in the figure is: 1. tray, 2, fixed block, 3, compression leg, 4, crimping end, 5, magnetic core, 6, printing board.
Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following will combine the drawings in the present invention to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments, based on the embodiments in the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.
The utility model provides a thick copper printed board power module magnetic core bonding frock, as shown in figure 1, including tray 1 that is used for placing magnetic core 5 and printed board 6, be used for carrying out fixed block 2 and at least one compression leg 3 of crimping to printed board 6, and compression joint end 4 of compression leg 3 can reciprocate and compress tightly fixed block 2 at the in-process of removing downwards, realizes the bonding of printed board 6 and magnetic core 5.
Offer respectively on the tray 1 and be used for carrying out the recess of location to magnetic core 5 and printed board 6, be respectively with 5 shape assorted first recesses of magnetic core to and with 6 shape assorted second recesses of printed board, first recess is for the inside sunken formation of second recess, after on printed board 6 and magnetic core 5 put into tray 1, printed board 6 is located the magnetic core 5 directly over. In order to achieve the best use effect, a plurality of avoiding grooves for avoiding elements on the printed board 6 are formed in the fixed block 2.
The two compression posts 3 are symmetrically arranged at the left side and the right side of the fixed block 2. In this embodiment, the bottom of the compression leg 3 is fixed on the tray 1, and the compression joint end 4 is located above the fixing block 2.
The utility model discloses bonding frock is when using, puts into the first recess on the tray 1 after 5 glue dispensing of magnetic core earlier, and in putting into the second recess on the tray 1 with printing board 6 again, then with the position of the fixed printing board 6 of fixed block 2 and magnetic core 5, reuse compression leg 3 compresses tightly fixed block 2, realizes the bonding of printing board 6 and magnetic core 5.
The utility model discloses the position relative to printed board 6 after the use of bonding frock can accurate control magnetic core 5 bonds, guarantees the unanimity of planar transformer and planar inductor parameter on the thick copper printed board, improves power module electrical parameter's stability; the overall height of the power supply module is controlled after the magnetic cores are bonded, so that the consistency of the installation of the power supply module is facilitated. The magnetic cores of the power supply modules can be bonded in batches.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
