Frequency antenna is connected, and the relay of combination is just radio-frequency relay, with control system and by the interactive relationship between control system.
This kind of relay has the high frequency characteristics that other relays do not have, and can reduce high-frequency loss than other relays.
Due to the characteristic requirements of radio-frequency relay rf load so that movable contact spring has larger space with base inner wall,
To ensure movable contact spring and static contact is completely reliable contacts, the rotation on movable contact spring in-plane need to be limited, conventional method be
Install insulation backing pin (such as Fig. 1) on base inner wall additional, this method need to change base inner wall structure, can influence radiofrequency characteristicses, meanwhile, peace
Multiple insulation backing pins are filled, the risk that the complexity and movable contact spring of structure are stuck can be increased.
Utility model content
In order to solve problem of the prior art, the utility model embodiment provides a kind of radio-frequency relay contact system.
The technical scheme is as follows：
On the one hand, the utility model embodiment provides a kind of radio-frequency relay contact system, including：Base, it is inserted into
The static contact component of base lower end, the flat cover for being fixed on base upper end, the movable contact spring being arranged between flat cover and base, it is inserted into
Push rod that on flat cover and one end is fixedly connected with movable contact spring and the spring being sleeved on push rod,
The limiting through hole inserted for push rod is offered on the flat cover, one end of the limiting through hole offers stopper slot,
Another end in contact of spring one end and push rod, and its other end contacted by stopper slot with flat cover,
The limiting through hole is mounting hole, and the cross section of the shaft of the push rod is the kidney-shaped corresponding with limiting through hole.
The beneficial effect brought of technical scheme that the utility model embodiment is provided is：
By setting mounting hole limiting through hole on flat cover, and by the push rod shaft being inserted on flat cover, it is set to and limits
The corresponding kidney-shaped of position through hole, the rotation of the movable contact spring being fixedly connected with push rod one end in the in-plane direction is limited with this, this
Sample is avoided installs insulation backing pin additional on the base of contact system, it is ensured that the simple continuity of base inner wall structure, improves
The radio frequency transmission performance of relay, meanwhile, it also simplify contact system structure, it is to avoid movable contact spring is by the dead wind of insulation stop pin card
Danger, improves the reliability of contact system.

Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type embodiment is described in further detail.
Embodiment one
The utility model embodiment provides a kind of radio-frequency relay contact system, and referring to Fig. 2, the contact system can be wrapped
Include：
Base 1, the static contact component 2 for being inserted into the lower end of base 1, the flat cover 3 for being fixed on base upper end, it is arranged on flat cover 3
Movable contact spring 6 between base 1, it is inserted on flat cover 3 and push rod 4 that one end is fixedly connected with movable contact spring 6 and is sleeved on top
Spring 5 on bar 4.
Referring to Fig. 3, the limiting through hole 301 inserted for push rod 4 is offered on flat cover 3, one end of limiting through hole 301 is offered
Stopper slot 302, is sleeved on one end of spring 5 on push rod 4 and another end in contact of push rod 4, and the other end of spring 5 passes through stopper slot
302 contact with flat cover 3.
Referring to Fig. 3, limiting through hole 301 is mounting hole, referring to Fig. 4, and the cross section of the shaft 401 of push rod 4 is to lead to spacing
The corresponding kidney-shaped in hole 301.
In the present embodiment, push rod 4 is fixedly connected through the kidney-shaped limiting through hole 301 on flat cover 3 with movable contact spring 6, this
