The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The core of the utility model is to provide a filter, this filter can solve owing to take a percentage piece end need bend the back and the tangent welding of resonance bar and lead to the difficult problem of guaranteeing of product uniformity to can greatly reduced product defective rate. Another core of the present invention is to provide a communication device including the above filter.

In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

It should be noted that the following directional terms such as "upper end, lower end, left side, right side" and the like are defined based on the drawings of the specification.

Referring to fig. 3 to 6, fig. 3 is a schematic structural diagram of a tap piece body according to an embodiment of the present invention; FIG. 4 is a schematic view of a welding structure of the tap piece body and the resonance rod in FIG. 3; FIG. 5 is a schematic cross-sectional view of FIG. 4; fig. 6 is a schematic structural view of a tap piece body welded to a flange portion of a resonance rod according to an embodiment of the present invention. Wherein, B1 is the centre-to-centre spacing after tap piece body and resonance bar welding, and C1 is the angle after tap piece body and resonance bar welding.

The embodiment of the utility model provides a filter, including taking a percentage piece body 1 and resonance bar 02, take a percentage piece body 1 and be equipped with the end 11 with the lateral wall rigid coupling of resonance bar 02 to this end 11 has and encircles face 111, encircles the face 111 and contacts laminating and rigid coupling with the lateral wall of resonance bar 02 to improve the area of contact of end 11 and resonance bar 02; that is, the end 11 having the embracing face 111 may embrace the outer sidewall of the resonance lever 02 in the circumferential direction of the resonance lever 02.

Certainly, according to actual needs, the tail end 11 and the outer side wall of the resonance rod 02 may be positioned by welding, and meanwhile, in order to ensure that the tap piece body 1 and the resonance rod 02 are tightly matched to ensure the positioning stability and reliability, the surrounding surface 111 of the tail end 11 may be specifically configured as an arc surrounding surface; thus, since the main body of the resonance rod 02 is annular, the arc-shaped surrounding surface can be closely attached to the outer side wall of the resonance rod 02.

On one hand, compared with the traditional filter, the bending angle A at the tail end of the tap piece is difficult to ensure the precision of the tap piece during production, and the tolerance of the angle C and the center distance B after the tap piece is welded with the resonance rod 02 is large, so that the product consistency is poor; the process of bending has been saved to the piece body 1 of taking a percentage of this application, and the piece body 1 of taking a percentage of this application can be the integrated into one piece structure, for example can be through setting up corresponding mould integrated into one piece, and its machining precision is high, can greatly reduced manufacturing cost.

On the other hand, in the prior art, the contact between the bent tap piece and the resonance rod 02 is line contact, so that the positioning reliability after the tap piece and the resonance rod 02 are welded is difficult to ensure; the application provides a take a percentage piece body 1 is through having the terminal 11 laminating with resonance bar 02 of embracing face 111, and take a percentage piece body 1 and resonance bar 02's contact is the face contact, can improve the area of contact of taking a percentage piece body 1 and resonance bar 02 like this greatly, thereby can make the location of taking a percentage piece body 1 and resonance bar 02 accurate, the precision is high, the assurance that can be fine like this takes a percentage piece body 1 and resonance bar 02 welded centre-to-centre spacing B1 and angle C1, as shown in fig. 5, thereby can guarantee the uniformity of product, and then can reduce the production defective rate.

Above-mentioned mode of setting up not only can make the piece body of taking a percentage 1 closely cooperate and concentric with resonance rod 02, can make the piece body of taking a percentage 1 and resonance rod 02 have advantages such as the position is reliable, the location is accurate and welding speed is fast moreover.

Further, the end 11 may be specifically configured to include two extending ends 112 symmetrically disposed with respect to the axis of the tap body 1, and both of the extending ends 112 extend along the circumferential direction of the resonant rod 02. That is, the end 11 can form an encircling surface 111 closely attached to the outer side wall of the resonant rod 02 by two extending ends 112 extending along the circumferential direction of the resonant rod 02.

Of course, according to actual requirements, any of the extending ends 112 may be configured to be tapered along the extending direction thereof, in other words, the width of any extending end 112 is smaller as it is closer to the end position. In addition, since the outer side wall of the resonant rod 02 is a circular surface, the inner side wall of any extension end 112 should be set to be a circular arc surface to ensure that the extension end 112 can be tightly attached to the outer side wall of the resonant rod 02, and the lengths of the two extension ends 112 can be adjusted according to actual positioning requirements; meanwhile, the joint position of the two extending ends 112 is a continuous smooth transition connection. In this way, the end 11 of the tap piece body 1 can form a surrounding structure similar to a "Y" shape.

Of course, the terminal 11 of the tap piece body 1 may have other different arrangement manners, as long as the arrangement manner capable of increasing the contact area between the tap piece body 1 and the resonance rod 02 to improve the reliability of the positioning of the two is within the protection scope of the present application, and the present disclosure will not be expanded one by one.

It should be noted that the resonant rod 02 may be configured to have a rod 021, and of course, the resonant rod 02 may also be configured to have a combination structure of the rod 021 and a flange 022, wherein the flange 022 is detachably connected to an upper end of the rod 021; thus, the end 11 of the tap body 1 can be welded to the outer sidewall of the rod body 021, as shown in fig. 4 and 5; of course, the tip 11 may also be welded to the outer side wall of the flange 022, as shown in fig. 6.

Compare on the lateral wall of the body of rod 021 of resonance bar 02 in terminal 11 welding, terminal 11 welds and can further increase the area of contact of taking a tap piece body 1 and resonance bar 02 on the lateral wall of flange 022, so, take a tap and rise the welding point that can make welding space increase of piece body 1, simultaneously, welding process is succinct more reliable, welding speed is faster, and the product uniformity is better.

In addition, the tail end 11 is also provided with an upper end surface used for depositing more tin liquid when the tail end 11 is welded with the outer side wall of the rod body 021, so that the tin liquid can be prevented from flowing along the outer side wall of the rod body 021; when the tip 11 is welded to the outer side wall of the flange 022, the upper end surface can prevent the tin liquid from flowing along the outer side wall of the flange 022, and the tip 11 may be configured to have a Y-shaped structure as a whole.
