Description
Technical field
The present invention relates to field of switches, more particularly to a kind of single-screw tubular type change-over switch.
Background technology
In the last few years, Military Electronic Equipment or consumer electronic product all show knowledge-intensive, technology content it is big,
The technical characterstics such as synthesization degree is high, construction complexity, this brings extreme difficulties to the test and maintenance of equipment and product, is based on
This demand, Auto-Test System (abbreviation ATE) are arisen at the historic moment, and it has automation, synthesization and quick measurement and diagnosis
Advantage.Microwave switch be realize ATE automation important microwave device, play signal route effect, therefore microwave switch can
ATE performance is directly determined by property.Change-over switch is one kind of microwave switch, is opened as shown in figure 1, change-over switch is four ports
Close, possess two relatively independent radio-frequency channels, corresponding two ports input microwave signal can be selected as needed, in addition
Two ports export microwave signal into part to be measured.
Currently, the relay assembly of change-over switch uses open by design, including duplex iron core, base, mounting seat, relay
Device coil, armature component, magnet, push rod and biasing plate.As shown in Figure 2 a, relay coil is welded on biasing plate, is being welded
Before coil, armature component is positioned between coil and biasing plate, forms the first drive component.Two pairs of duplex iron cores are arranged on
On base, core assembly is formed, mounting seat is arranged on core assembly, and magnet, which is placed on the relevant position of mounting seat, (to be paid attention to
Pole orientation), the second drive component is formed, is then positioned over push rod in the iron core of the second drive component, then first is driven
Component is installed to the relay assembly of the complete set just formed on the second drive component.
As shown in Figure 2 a and 2 b, two armature components and four push rods are moving components in traditional relay assembly,
In change-over switch handoff procedure, moving component is the part for being easiest to failure, as long as having an armature component or a push rod
Being stuck in motion can all cause change-over switch to fail, and coil may cross ambassador's paint in winding process due to pulling force in addition
Envelope curve is broken, and coat of paint is impaired to make the excessively high other reasonses of the resistance to drops of coil, coil temperature rise cause coil failure.
Parts are by machining or die casting and molding, due to machining tolerance, the physics of same part
Size is also not quite similar.Physical size tolerance stack causes the confining force and electromagnetic actuation force of traditional relay component difference path
Uniformity it is difficult to ensure that.
Traditional relay component is open structure design, and magnetic energy can be revealed caused by electromagnet and coil so that magnetic
Utilization rate reduces.The magnetic energy revealed in addition may influence whether other microwave sections outside other parts or switch in switch
Part, the magnetic energy of other magnetic parts may also have influence on the relay assembly of switch, so as to influence switch, switch
Electro Magnetic Compatibility largely reduces.
The relay assembly of conventional conversion switch is only used for change-over switch, and single-pole double throw, hilted broadsword are thrown more or by-pass switch
It is inapplicable so that the poor universality of the relay assembly.The other relay assembly needs to be arranged in RF transmission system,
Can not be separately formed, modularized design can not be carried out.
