Description

Filter

Technical field

The utility model relates to worry wave technology, particularly wave filter technology.

Background technology

The alleged filter of filter, especially people is a mature technology, and its purpose is the noise noise on the filtering circuit, so its applicable situation has finding more, the computer connecting wires as people use promptly is provided with this filter.

The principle of filter, be to utilize a magnetic core, its central authorities have hole, and then with the cladding of insulation material, electric wire then passes through the hole of this magnetic core in the outside, therefore, form hole, magnetic core is that two corresponding semicircles are formed usually, and central authorities are the semicircular arc-shaped recess of tool also, so that after two unit groups are upright, form circular opening.

In addition, owing to the outside need clad, so the shape of this cladding is slightly approximately corresponding to magnetic core, simultaneously, reserve a space that can supply magnetic core to locate, and, when not using, open wide, so that passing through the back, supply lines fastens, therefore, before not using transport with storage process in, magnetic core must not get loose with cladding, have only use pass through and combination after, that then makes every effort to clad is tight and firm, avoids separating and influence transmission quality.

So known filter is speciallyyed permit No. 2938446, No. 2801173, No. 2774454 as Japan, and No. 278747 novel patent of Taiwan patent announcement, " but the anchor clamps of filtering " all are with extremely complicated structure, to form filter, will be appreciated that, except the die cost height, outside the assembling complexity, its cost is higher naturally, this can be rated as blemish in an otherwise perfect thing to the industry utilization.

In view of this, the applicant is in line with being engaged in the electric component research and development experience with production and marketing all the year round, and concentrates on studies, and in the hope of overcoming above-mentioned disappearance, to develop a simple and easy and filter cheaply, through experiment repeatedly, creates the utility model.

The utility model content

The utility model purpose provides a kind of simple in structure, low cost, the filter that is easy to assemble.This filter comprises:

One shell is integrated two halves shell and link in flakes, and half and half shell is the shell chamber of tool depression, and each tool end wall of front and back end, and end wall central authorities then have a wall of arc-shaped recess and lack, and the end face edge portion in the outside then establishes the fastener that can fasten each other; And the inwall that forms the shell chamber is established a shell and is set part;

Two magnetic elements are that magnetic material is made, and size is corresponding to the shell chamber, and a recessed depression of magnetic is then had in the upper end, sets the part place corresponding to shell, magnetic element then is set sets part;

Magnetic element is set part and shell is set setting of part and make magnetic element be positioned the shell chamber, and buckles the ccontaining electric wire of hole that two magnetic spills become mutually when electric wire passes through the recessed two halves then of magnetic shell fastener.

Described filter, its magnetic element and half shell are semicircle sections.

Described filter, its fastener are coaks and buckle frame.

Described filter, it sets part is tenon bar and groove.

It is the shell chamber bottom of being located at half shell that described filter, its shell are set part, and magnetic element set part also correspondence be arranged at the magnetic element bottom.

It is to be located on the end wall of shell chamber that described filter, its shell are set part, and magnetic element is set the then corresponding two ends outer wall that is arranged at magnetic element of part.

It is that top for one section two discrete projections is the prominent tenon that circular arc extends outward that described filter, its shell are set part, and it can set part with the location by corresponding magnetic element.

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is the upright back of a utility model group schematic perspective view;

Fig. 3 is another embodiment schematic perspective view of the present utility model;

Fig. 4 is another embodiment that shell of the present utility model is set part.

Embodiment

For further disclosing concrete technology contents of the present utility model, see also diagram.

As shown in the figure, filter of the present utility model is to be combined by a shell 1 and two magnetic elements 2.

Wherein, shell 1 is that insulating material is made, and with one-body molded be good, and it is by two semicircle half rectangular shells 11, central authorities 12 link in flakes with one at least, and the upper end edge portion of this two halves shell 11, the fastener 13 that can fasten each other then is set respectively, and shown in Figure 1 as the utility model, half shell 11 wherein is a coak, 11 on second half shell is the button frame, but not as limit.In addition, an end wall 14 is respectively established in half and half shell, 11 its front and back ends, and be recessed to form wall and lack 15, and form a shell chamber 16 with the shell one common peripheral group of arc, and be that the magnetic element of chatting after making 2 can be located, so 16 bottoms, shell chamber, one shell can be set set part 17, as shown in Figure 1, be prominent tenon, but not as limit.

Magnetic element 2 is semicircle strips, be that permeability magnetic material is made, its size and shape is corresponding to aforementioned shell chamber 16, so that can be ccontaining, and for supplying passing through in conjunction with electric wire, so its inwall is that to be the magnetic of semicircular arc recessed 21, simultaneously, for make its can with aforesaid shell 1 location, so part 17 is set corresponding to aforesaid shell in its peripheral bottom, one magnetic element then is set sets part 22, shown in Figure 1 as the utility model, be groove.

Please consulting diagram again, when the utility model is implemented, during unused state, is that magnetic element 2 is inserted shell chamber 16 respectively, and sets part 22 via magnetic element and set the mutual embedding of part 17 with shell, and forms the location.

When implementing, it is recessed 21 then to exercise earlier the magnetic of the magnetic element 2 of electric wire by wherein, then again with second half shell 11 together with magnetic element 2 lids to second half shell 11, and the fastener 13 of two halves shell 11 is fastened each other, so, but promptly form electric wire shown in Figure 2 by the filter state of clamping.

Shown in Figure 3, be another embodiment of the present utility model, its difference, be that to set part 17 are tenon bars of being located at end wall 14 inwalls to shell, the magnetic element of magnetic element 2 is set the groove that part 22 then is located at the two ends outer wall of magnetic element 2, so, also can be and sets the location, but this also is a kind of embodiment of the present utility model, and it also can be via other various equivalent manners to reach.

Shown in Figure 4, it is another enforcement illustration that shell of the present utility model is set part 17, as shown in the figure, it is that one section shell being located at half shell, 11 bottoms is set part spare 17, this element be for the top by two discrete projections be the tenon shape that circular arc extends outward, and it can set part 22 corresponding to magnetic element, so, also can reach the purpose and the effect of location.

So, via enforcement of the present utility model, it can make mould simple, and as one pair of shell 1 mould, and one pair of magnetic element 2 mould can be produced, and when assembling and location, need only be single set action, also be single and fasten moving part, therefore, help a large amount of production to reduce cost, during assembling and for convenient.

The utility model discloses, and is preferred embodiment, and patent right category of the present utility model is not all taken off in Ju Bu change or modification and come from technological thought of the present utility model and be easy to the person of knowing by inference by the people who has the knack of this skill such as.
