Abstract
The utility model relates to an electric unit (1) which is arranged in a housing (2) sealed with a cover (3). An auxiliary element (6) is arranged between the cover (3) and the unit (1) in order to fix and make the electric unit resistant to vibration and impact.
Description
The utility model relates to the electric member in the chip structure, and toroidal core reactor especially, electric member are contained in the shell that closes with cap seal, and anti-shake and shock resistance fix.
By known this class A of geometric unitA of DE-U9111508.Wherein introduced a kind of toroidal core coil, coil is contained in the shell that central vault arranged, and is provided with a fixed disk for this reason, and the fixed disk above the toroidal core coil is fixed on member on the central vault by interference fit.
Therefore, the prerequisite of this known structure form is that shell should have a central vault.
The purpose of this utility model is the fixture of a kind of electric member of providing, make electric member can be contained in one relatively simple for structure and thereby lower-cost shell in, especially in this shell, do not have central vault.
Achieving the above object by the utility model is for fixing and establish an adapter between lid and member.
Adopt this version to have the following advantages, this paper starts the prior art of quoting relatively, can adopt not require special enforcement structure, as the shell of middle vault.Like this, the manufacturing cost of electric structure element can significantly reduce.
The plastic mould that this adapter is preferably made with heat resistant plastice, silicones for example, and have for example spherically or cylindrical, or this molding is designed to disc spring.
This adapter can also be made of plastic material.
Can describe the utility model in detail by means of the following example.
In the accompanying drawing:
Fig. 1 adopts the fixture of plastic mould;
Fig. 2 adopts the fixture of disc spring; And
Fig. 3 adopts the fixture of plastic material.
Represented a toroidal core reactor 1 among Fig. 1, it is contained in the shell, and shell is made up of bowl 2 and lid 3, and 4 places adopt for example ultrasonic bonding connection sealed to each other in the position for the two, and lead-out wire 5 is arranged at the bottom of bowl-shape outer casing member 2.
Be provided with a plastic mould 6 at bowl 2 with between covering 3, before packing into it for example for spherical or cylindrical, it with toroidal core reactor 1 anti-shake and shock resistance be fixed in the shell.
Fig. 2 has represented another kind of form of implementation, and wherein, the fixture of toroidal core reactor 1 has adopted a plastic mould that is designed to disc spring 7.
Plastic mould 6 or 7 the most handy a kind of heat resistant plastices are made among Fig. 1 and 2, for example silicones.
Fig. 3 has represented another kind of form of implementation, and wherein, the fixing of toroidal core reactor 1 realizes that by a kind of plastic material spare 8 plastic material spare 8 is located between lid and the toroidal core reactor 1.
Claims (5)
1. the electric member in the chip structure, especially toroidal core reactor, this electric member are contained in the shell with the lid sealing, it is characterized by: establish adapter (6,7,8) between lid (3) and member (1).
2. according to the described electric member of claim 1, it is characterized by: adapter (6,7) is designed to the plastic mould that heat resistant plastice is made.
3. according to the described electric member of claim 2, it is characterized by: adapter (6,7) is made by silicones.
4. according to the described electric member of claim 3, it is characterized by: adapter (6) has spherical or cylindrical.
