Into a laborious lever, the contact of remote measurement contact is smaller, and the movable contact of this mode and stationary contact are line and face
Contact contact point is not fixed, and contact is small, and resistance variations are big.The third mode, remote measurement contact use and radio frequency contact machinery
The mode of linkage, the contact of such a mode remote measurement contact are produced, contact by movable contact spring deflection in itself
It is smaller, and contact position is fixed between contact, it is not easy to clear the pollution off, after long-term work, contact resistance increase, contact between contact
It is bad, ultimately cause contact failure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of RF coaxial relay remote measurement contact mechanism, and it is touched
The contact resistance of point is small, and contamination resistance is strong, long working life.
In order to solve the above technical problems, the utility model provides a kind of RF coaxial relay remote measurement contact mechanism, it
Including stationary contact, movable contact spring, circuit board, auxiliary push-rod；
Movable contact spring is using 0.1 millimeter of thickness, the rectangle beryllium-bronze piece of surface gold-plating, one end weldering of movable contact spring length direction
Connect on circuit boards；
Stationary contact uses the copper wire of surface gold-plating, and stationary contact is substantially in inverted U-shape, and stationary contact passes through its open side and circuit
Plate weld；
Stationary contact is in the middle part of the length direction of movable contact spring, and the material of auxiliary push-rod is polyetherimide material, and auxiliary pushes away
Bar pass from bottom to top circuit board and with another end in contact of the length direction of movable contact spring.
For the sake of simple declaration problem, below to a kind of RF coaxial relay remote measurement contact machine described in the utility model
Structure is referred to as this remote measurement contact mechanism.
The advantages of this remote measurement contact mechanism：A kind of RF coaxial relay remote measurement contact mechanism described in the utility model,
Its stationary contact is located at the middle part of movable contact spring length direction, and the contact point of auxiliary push-rod and movable contact spring is located remotely from movable contact spring and circuit
One end of plate weld.The arm of force of stationary contact is less than the arm of force of auxiliary push-rod and movable contact spring contact point, and overall one forms laborsaving thick stick
Bar, so the pressure at stationary contact is larger, contact resistance can be reduced, reliability is added and also extend service life.
The principle of this remote measurement contact mechanism and explanation：Excellent remote measurement contact is required in life cycle, is had between contact
There is small and stable contact resistance.According to contact resistance empirical equation：
In formula：FjFor contact force (N), RjContact resistance (μ Ω), KjFor material coefficient, m be with contact surface shape, contact
The relevant coefficient such as form.
According to above formula, increasing the contact can of contact effectively reduces resistance, and this is also largely effective and cost is low
Honest and clean mode.
To reach the more preferable using effect of the utility model, preferred scheme is as follows：
As preferable：The shape of the closed side of described stationary contact is in downwardly extending arc.
When movable contact spring contacts with stationary contact, auxiliary push-rod continues up displacement, and movable contact spring is deformed upon and sealed around stationary contact
Close relative motion at the downwardly extending arc of side.The oxide-film after long-term use on stationary contact and organic contamination can effectively be removed
Thing, stability can be improved with significantly more efficient reduction contact resistance, extend working life.
Brief description of the drawings
Fig. 1 is the structural representation of this remote measurement contact mechanism.
Fig. 2 is Fig. 1 A-A sectional views.
Fig. 3 is the structural representation for the RF coaxial relay for being provided with this remote measurement contact mechanism.
Embodiment
As shown in Figure 1-2, a kind of RF coaxial relay remote measurement contact mechanism, it includes stationary contact 1, movable contact spring 2, circuit
Plate 3, auxiliary push-rod 4；
Movable contact spring 2 is using 0.1 millimeter of thickness, the rectangle beryllium-bronze piece of surface gold-plating, one end of the length direction of movable contact spring 2
(described one end is fixing end) is welded on circuit board 3, so that movable contact spring 2 is placed with circuit board 3；
