Description

Coaxial radio frequency switch capable of preventing poor contact

Technical Field

The utility model relates to a coaxial radio frequency switch, more specifically say, the utility model relates to a can prevent contact failure 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. Due to the characteristic of the material of the conductor reed of the conventional coaxial radio frequency switch, the conductor reed can deform when a fixed conductor is contacted, so that the contact of the switch is poor, and the performance of the coaxial radio frequency switch is influenced.

SUMMERY OF THE UTILITY MODEL

In view of the above. Because the characteristic of current coaxial radio frequency switch's conductor reed material, the conductor reed can produce when lieing in the fixed conductor contact and warp, causes the contact failure of switch, influences the problem of coaxial radio frequency switch's performance, the to-be-solved technical problem of the utility model is to provide a can prevent the coaxial radio frequency switch of contact failure.

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

the coaxial radio frequency switch capable of preventing poor contact comprises a switch body, a push rod, a conductor reed arranged on the lower portion of the push rod and a fixed conductor, and is characterized in that clamping blocks are arranged at two ends of the conductor reed, a clamping groove is formed in the upper portion of the fixed conductor, a clamping block is arranged in the clamping groove, and the clamping block is fixed through the clamping block after being clamped with the clamping groove.

The preferable scheme of the scheme is as follows: the clamping blocks are positioned on two sides of the fixed conductor.

The preferable scheme of the scheme is as follows: the clamping block is provided with a return spring.

The preferable scheme of the scheme is as follows: the clamping blocks are 2 and the front ends of the clamping blocks are provided with bevel edges.

The preferable scheme of the scheme is as follows: the distance between the 2 oblique edges is greater than the width of the clamping block.

The preferable scheme of the scheme is as follows: the inner side of the clamping block is provided with a supporting sheet which can be contacted with the switch body when the conductor reed descends.

Compared with the prior art, the utility model discloses following beneficial effect has: the clamping block is arranged below the conductor reed, the clamping groove is formed in the upper portion of the fixed conductor, the clamping block is arranged in the clamping groove, when the conductor reed descends, the clamping block is clamped with the clamping groove, the clamping block is clamped tightly by the clamping block, looseness cannot occur, the problem of poor contact cannot occur, and the performance of the coaxial radio frequency switch is improved. The clamping block is provided with a return spring, when the conductor spring plate rises, the clamping block returns, and the conductor spring plate is clamped again after next contact.
