Seesaw assembly for coaxial radio frequency switch

Technical Field

The utility model relates to a coaxial radio frequency switch, more specifically say, the utility model relates to a seesaw subassembly for coaxial radio frequency switch.

Background

Relays are electromechanical switches operated by current in one circuit to control the conduction of current in another circuit. A typical relay basically comprises an electromagnet and a soft iron bar close to the electromagnet, a movable contact connected to the soft iron bar and held in its normal position by a spring. When the electromagnet is energized, it exerts a force on the soft magnetic rod, overcoming the tension of the spring, moving the contacts to close or open the circuit. When the electromagnet is de-energized, the contacts return to the original position. Some relays have multiple contacts, some are hermetically encapsulated, and some have built-in circuitry that delays the contact closing after actuation; some relays are step-by-step and some relays are self-holding.

Coaxial radio frequency switches are a special type of electromechanical switch in which a Radio Frequency (RF) signal is connected or disconnected between terminals in the switch. Generally, a coaxial rf switch utilizes the seesaw principle to push a conductor spring into contact with a pair of coaxial conductor heads and connect a signal path between two coaxial conductors. The thrust is typically generated by an electromagnetic drive assembly. When the pushing force on the push rod is removed, the restoring spring will lift the push rod (and the conductor reed), thereby breaking the signal path between the coaxial conductors. It is important that there be some mechanism of over travel in the pushrod assembly to maintain sufficient force and stability of contact when the conductor reed is in contact with the coaxial conductor. However, when the rocker of the conventional coaxial radio frequency switch pushes the push rod, the rocker will shake, so that the contact stability between the conductor reed and the fixed conductor is poor, and the performance of the coaxial radio frequency switch cannot be guaranteed.

SUMMERY OF THE UTILITY MODEL

To above-mentioned current coaxial radio frequency switch's seesaw when promoting the push rod, the support column of seesaw below can produce the striking with the seesaw because there is not elasticity to it is not good to make the stability of conductor reed and fixed conductor contact, leads to the problem that coaxial radio frequency switch performance can not obtain the assurance, the to-be-solved technical problem of the utility model is to provide a seesaw subassembly for coaxial radio frequency switch.

In order to solve the technical problem, the utility model discloses a technical scheme is:

the utility model provides a seesaw subassembly for coaxial radio frequency switch, includes pivot, seesaw and support column, its characterized in that, the seesaw is located the top of support column, the below of seesaw is provided with the arch, the support column is provided with the elastic block for hollow and support column, the seesaw contacts with the elastic block at the operation in-process.

The preferable scheme of the scheme is as follows: the elastic block is oval, and the upper portion of the elastic block and the portion of the lower protruding contact of the warping and warping portion are provided with arc-shaped grooves.

The preferable scheme of the scheme is as follows: and an anti-skid ball is arranged in the arc-shaped groove.
