Abstract
Novel tuning punching press cover plate, the main body of described punching press cover plate is flat cold-rolling and punching steel plate, this cold-rolling and punching steel plate is laid with multiple punching, all punchings on described cold-rolling and punching steel plate are all provided with the flange of annular towards the same face of cold-rolling and punching steel plate, the inwall of this annular flange and punching forms the installing hole for installing tuning screw jointly, and the inwall of installing hole is provided with the screw thread that can coordinate with tuning screw.While guarantee tuning screw installing hole has enough useful threads, material thickness compares traditional aluminium profiles at least can reduce 2mm, have more space can be increased in cavity body dark on, reasonably can solve the confinement problems that chamber exists deeply always.
Description
Technical field
The utility model relates to the cover plate of the communication equipments such as filter, duplexer, mixer.
Background technology
Along with developing rapidly of mobile communication, the design optimization of the communication products such as all types of filters, duplexer, mixer is except except aspect of performance optimization, and Design Processing is necessary optimization also.The punching press debugging cover plate die sinking of the product such as conventional filter, duplexer all adopts the aluminium type material of 2.5mm-3mm thickness mostly.Blocked up sheet material not only adds material cost, and when overall device thickness requirement is determined, cover plate later also necessarily limit the degree of depth of resonant cavity.For effectively cost-saving, saving resource, improve synthesized competitiveness, development of new tuning punching press cover plate is necessary.
Utility model content
Technical problem to be solved in the utility model is to provide and overcomes above-mentioned defect, provides a kind of novel tuning punching press cover plate.
The utility model for solving the problems of the technologies described above adopted technical scheme is: novel tuning punching press cover plate, the main body of described punching press cover plate is flat cold-rolling and punching steel plate, this cold-rolling and punching steel plate is laid with multiple punching, all punchings on described cold-rolling and punching steel plate are all provided with the flange of annular towards the same face of cold-rolling and punching steel plate, the inwall of this annular flange and punching forms the installing hole for installing tuning screw jointly, and the inwall of installing hole is provided with the screw thread that can coordinate with tuning screw.
Further, described tuning screw is provided with nut with matching and lock washer.
Further, the thickness of described cold-rolling and punching steel plate is 1mm.
Further, the inwall of described installing hole is provided with the effective thread of 2-2.5mm.
Further, the functional surfaces of described punching press cover plate is provided with silver coating, copper plate or nickel coating.
Further, non-functional of described punching press cover plate is provided with conductive oxide layer.
Cover plate of the present utility model adopts cold-rolling and punching steel plate to be base material, by going out the mode of the punching with annular flange, while guarantee tuning screw installing hole has enough useful threads, material thickness compares traditional aluminium profiles at least can reduce 2mm, have more space can be increased in cavity body dark on, reasonably can solve the confinement problems that chamber exists deeply always.In addition, adopt cold-rolled steel sheet, compare with conventional aluminum section bar on communication products produce the coefficient of expansion, temperature drift impact little, product comprehensive stability raising.And cold-rolled steel sheet hardness ratio aluminium is high, be not easy distortion; Easier punching press after thickness of slab is thinning; Produce assembling pressing ability good.By said structure mode, for realizing manufacturing more Appropriate application space, product that properties of product are stable provides possibility.
The utility model cover plate is a kind ofly upgrade excellent resonance covering plate structure, and material is bought convenient, requires low to material and making, and post-production is convenient, and the time is short, and batch production cost is lower.

Embodiment
Realizing the adoptable mode of the utility model for illustrating, being specifically described below in conjunction with accompanying drawing.
As shown in Fig. 4-Fig. 8, the main part of novel tuning punching press cover plate of the present utility model adopts flat cold-rolling and punching steel plate 1, and its thickness can be only about 1mm.Not only can reduce material cost by the minimizing of thickness, space can also be saved for increasing the resonant cavity degree of depth.In order to ensure normal mounting tuning screw 2 on so thin cold-rolling and punching steel plate, the mode of the utility model employing punching press forms multiple punchings 5 as shown in the figure on cold-rolling and punching steel plate, and around punching 5, forming the flange 6 of annular, the flange 6 of all punchings 5 is all towards the same face of cold-rolling and punching steel plate 1.Namely this annular flange 6 forms the installing hole for installing tuning screw 2 jointly as the inwall of extension and punching 5.Due to stretching out of annular flange 6, add the hole depth of installing hole, make its inwall has enough length the screw thread that can coordinate with tuning screw 2 is set, usually will ensure that the inner wall section a of installing hole is provided with the effective thread of 2-2.5mm.Thus, namely solve reduction cover sheet thickness and ensure the contradiction between tuning screw installing hole hole depth.
When communication products adjusting functions such as later stage filter, duplexer, mixers, tuning screw 2, nut 3 and lock washer 4 are arranged on punching press cover plate, and its dimensions is determined according to specific product.
Further, the functional surfaces of described punching press cover plate can arrange silver coating, copper plate or nickel coating, can select electric conductive oxidation for non-functional.
