Description
Technical field
The present invention relates to a kind of magnetic element, relate in particular to a kind of metal terminal through the surface mounted magnetic element after improveing.
Background technology
In magnetic element such as EPC type magnetic core, coil end needs to be electrically connected with metal terminal, can guarantee after two metal terminal energisings in loop of formation, coil two ends.In the prior art, because the metal terminal surface is smooth, and coil end has certain force of strain and distortion, can not be close on the junction surface of metal terminal, makes the temporary fixed unreliable of metal terminal and coil end, influences the reliability of its electrical connection; So, usually need be when operation with hand or other utensil fixed coil ends the accuracy to guarantee that coil end and metal terminal fully contact and guarantee binding site, but this can increase the difficulty that adds man-hour and the complexity of technology undoubtedly.
For improving the reliability that metal terminal is connected with coil end, as a kind of mounting structure disclosing in the Chinese patent 200410103831.8: splicing ear 4 is conductive metal terminals, the cross section forms the コ font, and be provided with the faying face 4a of the extension of an end band angle, the shape projection that outwards meets at right angles from these faying face two ends 4b along the notch direction from central portion.This splicing ear 4 is used to make winding terminal 3a, the 3b of air core coil 3 consistent with faying face 4a, 4b, and by protruding 4b bending is carried out clamping to it.In this patent, being connected between splicing ear and the coil is reliable, the surface mounted sensor that can obtain having stronger anti-drop impact performance.But from its manufacture process, after metal terminal and air core coil are close to, cut off, more protruding 4b is bent inwards the clamping winding terminal by the end of the length that is consistent with the faying face 4a of splicing ear 4 to air core coil.Then by soldering or thermo-compressed, welding etc. in conjunction with kink, winding terminal 3a, 3b electrically are connected with splicing ear 4.
By the explanation of disclosed structure of above-mentioned patent and manufacture process thereof, need by projection 4b being bent terminally with the clamping coiling, need an extra operation that projection 4b is bent, its manufacturability relative complex of being provided with.
Summary of the invention
The object of the present invention is to provide a kind of surface mounted magnetic element, this magnetic element is fixedlyed connected with metal terminal reliably at the assurance coil end, and manufacturing process is simple.
The present invention is achieved through the following technical solutions:
A kind of surface mounted magnetic element, comprise coil, magnetic core and metal terminal, wherein said metal terminal is provided with and is used for fixed part of fixing with described magnetic core and the junction surface that is used to install described coil end, described junction surface by the junction surface main body, be connected in the card arm on the main body of described junction surface, and be formed at the grasping part that is used to hold described coil end between described card arm and the described junction surface main body and constitute.
In the present invention, when the coil of magnetic element is installed, coil end placed between card arm and the junction surface main body form in the grasping part, and gently press the card arm promptly to reach with finger or instrument metal terminal and coil end are carried out tentatively fixing effect, compared with prior art, fixed form of the present invention is more reliable; Simultaneously during fabrication, metal bond portion main body can be one time punching molded with the card arm, do not need extra manufacturing procedure, and manufacturing process is simple.
Further structure of the present invention is:
Described card arm two ends all are connected with described junction surface main body and make described grasping part become closed.The grasping part of closed can avoid coil end to withdraw from grasping part.At this moment:

Described card arm is circular-arc.Be that coil end adopts circle or semicircular structure.
For the grasping part of above-mentioned closed, can also make following structure: the end that described card arm is connected with described junction surface main body is card arm link, and the other end is unsettled and form card arm sling dead end, and described grasping part becomes non-closed.The grasping part of non-closed can make things convenient for coil end to pack into or take out, and simultaneously preliminary fixedly the time, the card arm has bigger and easier deformation, effectively reaches the effect of tentatively fixing.At this moment:
Described card arm sling dead end is linearly, and promptly coil end adopts laminated structure; Per two described card arms become a pair of, and its card arm sling dead end surrounds described non-closed grasping part relatively, and two of being oppositely arranged card arm clamps coil end, and fixed effect is more reliable, and in this structure, coil end inserts from the grasping part top.
Described card arm on the described metal terminal is at least two, and these at least two card arms are provided with along described coil end direction is parallel.A plurality of card arms make the clamping effect even more ideal.
Described at least two card arm uniform distances are provided with.This structure makes coil end stressed processing, good looking appearance of evenly, also making things convenient for fixedly the time.
Described junction surface main body and described card arm are whole flaky material punch forming.Punching press on whole flaky material and form the junction surface main body with the card arm, good manufacturability.
To sum up, advantage of the present invention is:
1, by junction surface main body on the metal terminal and the formed grasping part of card arm coil end is fixed, fixing more reliable;
2, grasping part is close-shaped, can avoid coil end to withdraw from, and can conveniently coil end be packed into and can take out and grasping part is non-closed; Two card arms that are oppositely arranged clamp coil end, and fixed effect is more reliable.
3, coil end can be laminated structure, also can be for circular or semicircle;
4, a plurality of card arms make the clamping better effects if;
5, metal terminal is by the flaky material punch forming, and processing technology is good.
