Abstract
The invention belongs to the technical field of microwave communication, and in particular relates to an aluminum alloy cast power dividing bar. The power dividing bar comprises an aluminum bar and is characterized in that: the aluminum bar is formed by casting; one end of the aluminum bar is provided with an annular groove; the outer side section of the annular groove is provided with a screw hole which vertically penetrates the aluminum bar; the other side of the annular groove is provided with a three-step bar which diminishes step by step; and the central position of the end of the three-step bar is provided with a screw hole. The power dividing bar is formed by casting, so that the consumption of aluminum alloy materials or aluminum ingots can be greatly reduced, production efficiency is improved, production cost is reduced, market demand on a large scale is met, and products have high competitiveness in the market.
Description
Technical field
The invention belongs to the accessory in a kind of passive microwave device, specifically is that a kind of merit is divided rod.
Background technology
It is the inner wire of passive microwave device cavity power splitter that merit is divided rod.The cavity power splitter is a kind of one road microwave input signal energy to be divided into the device of two-way or multichannel output signal, is widely used in technical field of micro communication.It all is to be processed into through numerically controlled lathe or engine lathe with copper rod or aluminium bar that traditional merit is divided rod, and the metal cutting waste material more than 30% is arranged, the material cost height, and production efficiency is low, and the product price height lacks market competition advantage, also is difficult to satisfy market demand in enormous quantities.
Summary of the invention
The purpose of this invention is to provide a kind of die casting merit and divide rod, after the die casting one-shot forming, need hardly to divide rod to carry out metal cutting processing to merit, production process and material consumption have been reduced, save cost of labor, improved production efficiency, can reduce product cost about 25%, the product price advantage manifests, and also can satisfy market demand in enormous quantities.
The technical scheme of invention
A kind of aluminium alloy compression casting merit is divided rod, include aluminium bar, it is characterized in that described aluminium alloy bars is through the one-time formed aluminium bar of die casting, described aluminium bar one end has annular groove, the screw hole that runs through is arranged on the segmentum laterale of described annular groove, annular groove is generally 3 grades with the multistage step aluminium bar of the other end for successively decreasing step by step down to aluminium bar, and there is screw hole the end of described step aluminium bar.
The advantage of invention
The present invention adopts die cast to produce aluminium alloy merit branch rod, can improve production efficiency greatly in the consumption that reduces aluminum alloy materials or aluminium ingot, has reduced production cost, satisfies market demand in enormous quantities, and product has more competitive advantage on market.
Description of drawings
Fig. 1 is a structural representation of the present invention, and Fig. 2 is a cavity power splitter schematic diagram.
Embodiment
As shown in Figure 1, a kind of aluminium alloy compression casting merit is divided rod, include aluminium bar 1, aluminium bar is the die cast aluminium bar, aluminium bar 1 one ends have annular groove 3, the outside of annular groove 3 is positioned on the center of aluminium bar 1 one ends, the screw hole 2 that runs through aluminium bar is arranged, to become 90 ° with aluminium bar 1 is vertical behind the screw hole 2 assembling screws, the both sides of screw hole 2 will link to each other with the connector 11 of cavity power splitter (Fig. 2) respectively, the output microwave signal, annular groove 3 is with the 3 step aluminium bars (4 of the other end for successively decreasing step by step down to aluminium bar 1,5,6,7), in the center, end of step aluminium bar is screw hole 8, and screw hole 8 links to each other with the connector 12 of cavity power splitter (Fig. 2) end, the input microwave signal.
As shown in Figure 1, it is stair-stepping revolving body that described body (1) merit is divided rod, and the diameter of revolving body is increased to output gradually by input (7), thereby makes that the insertion loss of body assembling rear chamber power splitter of the present invention is little, and on the standing wave, and frequency-selecting is good.
Claims (5)
1. an aluminium alloy compression casting merit is divided rod, it is characterized in that: merit divides rod 1 to be aluminium alloy compression casting, one-shot forming, and body (1) is the aluminium bar that successively decreases step by step (4,5,6,7).
2. merit according to claim 1 is divided rod, and it is characterized in that: an end (4) of described body (1) has annular groove (3).
3. divide rod according to the described merit of claim 1, it is characterized in that: the outside of described body (1) annular groove (3) is the screw hole (2) that runs through aluminium bar, links to each other the output microwave signal with the connector (11) of Fig. 2 cavity power splitter.
4. divide rod according to the described merit of claim 1, it is characterized in that: a side (4,5,6,7) of described body (1) annular groove has the 3 grades of step rods that successively decrease step by step.
5. divide rod according to the described merit of claim 1, it is characterized in that: there is screw hole (8) at the center, end of the other end (7) of described one (1), links to each other the input microwave signal behind screw hole (8) the assembling screw with cavity power splitter connector (12).
