Embodiment

It refer to shown in Fig. 1 to Fig. 3, that show the concrete structure of the preferred embodiment of the utility model, include First iron core 10, the second iron core 20, skeleton 30 and coil 40.

First iron core 10 includes the first pedestal 11 and in the first stem 12 extended on the first pedestal 11, and first The outer surface of pedestal 11 and the outer surface of the first stem 12 are sprayed formed with coatings layer 13.

Second iron core 20 includes the second pedestal 21 and in the second stem 22 extended on the second pedestal 21, and second The contact face of pedestal 21 is bonded with the coatings layer 13 on the end face of the first pedestal 11, the contact face of the second stem 22 with Coatings layer 13 on the end face of first stem 12 is bonded.

The skeleton 30 includes reel 31 and is integrally formed two mounting seats 32 being connected with the both ends of reel 31 respectively, The reel 31 is sheathed on the outer surface of the stem 22 of coatings layer 13 and second of the outer surface of the first stem 12, two mounting seats Conducting terminal 33 is provided with 32, two mounting seats 32 expose the first iron core 10 and the second iron core 20 respectively.In the present embodiment The produced by insert molding of conducting terminal 33 is fixed in mounting seat 32, and being intervally arranged in each mounting seat 32 has four aforesaid conductive terminals 33, each conducting terminal 33 horizontally outward extends.
