Description
Technical field
The present invention relates to field of switches, particularly a kind of single-screw tubular switched switch.
Background technology
In the last few years, Military Electronic Equipment or consumer electronic product all show the technical characterstics such as knowledge-intensive, technology content is large, synthesization degree is high, complex structure, this brings extreme difficulties to the test of equipment and product and maintenance, based on this demand, Auto-Test System (being called for short ATE) is arisen at the historic moment, it has automation, the advantage of synthesization and Quick Measurement and diagnosis.Microwave switch is the important microwave device realizing ATE automation, and play the effect of signal route, therefore the reliability of microwave switch directly determines the performance of ATE.Change over switch is the one of microwave switch, as shown in Figure 1, change over switch is four port switch, has two relatively independent radio-frequency channels, can select corresponding two ports input microwave signal as required, microwave signal exports in be measured by two other port.
Current, the relay assembly of change over switch adopts open by design, comprises duplex iron core, base, mount pad, relay coil, armature component, magnet, push rod and biasing plate.As shown in Figure 2 a, relay coil is welded on biasing plate, before welding coil, armature component is positioned between coil and biasing plate, forms the first driven unit.Two pairs of duplex iron cores are arranged on base, form core assembly, mount pad is arranged on core assembly, magnet is placed on (attention pole orientation) on the relevant position of mount pad, form the second driven unit, then push rod is positioned in the iron core of the second driven unit, then the first driven unit is installed to the relay assembly of the complete set that the second driven unit is just formed.
As shown in Figure 2 a and 2 b, in traditional relay assembly, two armature components and four push rods are moving components, in change over switch handoff procedure, moving component is the parts the most easily lost efficacy, change over switch all can be caused to lose efficacy as long as have an armature component or a push rod to be stuck when moving, coil is in winding process in addition, may cross ambassador's enamelled wire break due to pulling force, and coat of paint is impaired makes the resistance to drops of coil, coil temperature rise is crossed high other reasons and caused coil failure.
Parts are by machining or die casting and molding, and due to machining tolerance, the physical size of same part is also not quite similar.Physical size tolerance stack causes the confining force of the different path of traditional relay assembly and electromagnetic actuation force consistency to be difficult to ensure.
