Abstract
The utility model discloses a low-pass structure body, which comprises a high-low impedance unit made up of a metal main rod and a metal disk on the metal main rod. One end of the metal main rod is provided with a connection rod for connection between the low-pass structure body and an external structure piece; the connection rod is internally provided with a blind hole for insertion connection of the external structure piece; and the side wall of the connection rod is provided with through holes for electroplating the inner wall of the blind hole. As the through holes are arranged on the blind hole of the low-pass structure body, the deep part of the blind hole can be uniformly electroplated, the electroplating quality of the inner wall of the blind hole can be improved, the electroplating defect rate is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to the communications field, is specifically related to a kind of lowpass structures body and comprises the cavity body filter of this lowpass structures body.
Background technology
Cavity body filter has important function as the communication equipment of a kind of frequency-selecting and inhibition signal in the communication radio frequency field.
With reference to figure 1; comprise in the existing cavity body filter for the lowpass structures body 1 that suppresses high-frequency signal; lowpass structures body 1 generally includes a blind hole 10 that connects electric capacity accessory or other structural members; lowpass structures body and blind hole inside all need be electroplated, because blind hole is darker, in electroplating process; the blind hole inwall is not because electroplate liquid circulates; usually poor plating such as peeling, blackout can occur, and be difficult for surveying, increase the quality risk.
The utility model content
The utility model is for the problem of the blind hole poor plating that solves lowpass structures body of the prior art, a kind of lowpass structures body is provided and comprised the cavity body filter of this kind lowpass structures body.
A kind of lowpass structures body, comprise the height impedance unit of being formed by the metal dish on metal mobile jib and the metal mobile jib, one end of described metal mobile jib is provided with the connecting rod that is connected with the external structure part for described lowpass structures body, be provided with the blind hole of pegging graft for the external structure part in the described connecting rod, the sidewall of described connecting rod is provided with for the through hole of electroplating the blind hole inwall.
Further, described through hole is arranged near on the inwall at the bottom of the blind hole hole.
Further, described through hole has at least two, the not collinear distribution of described at least two through holes on the axial direction of connecting rod sidewall.
Further, described through hole has two, and described two through holes are symmetrically distributed along the radial direction of connecting rod sidewall.
Perhaps, described through hole has at least two, and described at least two through holes distribute at the same line of the axial direction of connecting rod sidewall.
Perhaps, described through hole has one.
Further, the length dimension of described blind hole is greater than the diameter dimension in the blind hole aperture of twice.
A kind of cavity body filter comprises lowpass structures body described above, and described cavity body filter comprises chamber hole, and described lowpass structures body is assemblied in the described chamber hole.
Blind hole in the utility model in the lowpass structures body arranges through hole can make the blind hole depths can both obtain uniformly-coating, improves the electroplating quality of blind hole inwall, reduces the poor plating rate, enhances productivity.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the generalized section of a kind of lowpass structures body in the prior art;
Fig. 2 is the generalized section of a kind of lowpass structures body among the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment one,
With reference to figure 2, a kind of lowpass structures body 2, comprise the height impedance unit of being formed by the metal dish on metal mobile jib 21 and the metal mobile jib, one end of described metal mobile jib 21 is provided with the connecting rod 22 that is connected with the external structure part for described lowpass structures body 2, be provided with the blind hole 23 of pegging graft for the external structure part in the described connecting rod 22, the sidewall of described connecting rod 23 is provided with for the through hole 24 of electroplating blind hole 23 inwalls.
Blind hole 23 is used for connecting electric capacity accessory or other structural members, and the blind hole inwall need electroplate to satisfy requirement on electric performance.The length dimension of the blind hole 23 in the present embodiment is greater than the diameter dimension in the aperture of twice, because blind hole is darker, at the bottom of the hole and the easy poor plating of inwall, so the utility model can both arranged through hole 24 near the inwall at the bottom of blind hole 23 holes by uniformly-coating in order to make blind hole inwall and blind hole depths.
Concrete, below be several preferred through hole set-up modes.Can further, two through holes can be set at least two through holes of not collinear setting of the axial direction of connecting rod sidewall, two through holes 24 are symmetrically distributed along the radial direction of connecting rod sidewall, as shown in Figure 2; Also can at least two through holes be set at the same line of the axial direction of connecting rod sidewall; Can also near the inwall at the bottom of the blind hole hole, a through hole only be set.Below only enumerated several preferred implementations that through hole is set, the number of through hole and position do not constitute restriction of the present utility model.
Arranging of through hole can make the blind hole depths can both obtain uniformly-coating, improves the electroplating quality of blind hole inwall, reduces the poor plating rate, enhances productivity.
A kind of cavity body filter comprises above-mentioned lowpass structures body, and the lowpass structures body is assemblied in the chamber hole of cavity body filter.
Used specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
