Description
Technical field
The utility model is related to wave filter technology field, especially a kind of connection structure of filter element.
Background technology
Filter is a kind of device or circuit having processing effect to signal.Filter is divided into active filter and passive filter
Wave device.Main function is：Allow useful signal is as zero-decrement as possible to pass through, the decaying as big as possible to garbage signal.Filter
Port there are two general, an input signal, an output signal can gate one by filter using this characteristic
Square wave group or compound wave of making an uproar, and obtain the sine wave of a specific frequency.
For current filter, connecting rod and the elasticity that a dielectric-sleeve assembles are difficult to control, are filled to production
With having an impact with RF index.
Utility model content
Purpose of the utility model is to solve the above problems, devise a kind of connection structure of filter element.
To achieve the above object, the utility model provides the following technical solutions：A kind of connection structure of filter element, packet
Head rod, the second connecting rod, insulation sleeve, support deck, fixing body are included, the fixing body is internally provided with support deck,
Described head rod one end is inserted into inside insulation sleeve, and described insulation sleeve one end is inserted into the inside of the second connecting rod, described
Support card seat is arranged outside one end of second connecting rod, the head rod is internally provided with triangle convex, the insulation
Internal set is that plane is used for and triangle convex interference occlusion.
Preferably, one end of the head rod is provided with the annular groove for installing support deck.
Preferably, second connecting rod is the cylindrical structure of narrowing toward each end broad in the middle, and in second connector
Between and both sides be chamfered transition.
Preferably, the material of the insulation sleeve is high temperature polymeric materials.
Preferably, the support deck is discoid, and the support base is connected with fixing body interference fit.
Using a kind of connection structure for filter element that the technical solution of the utility model makes, the technical program passes through
Triangle convex is set outside head rod, head rod and insulation sleeve are closely joined together.The utility model has
There is feature simple in structure and convenient and practical.

It is indirectly connected, can be the connection inside two elements.For the ordinary skill in the art, it can be managed with concrete condition
Solve the concrete meaning of above-mentioned term in the present invention.
The utility model provides a kind of connection structure of filter element as shown in Figs. 1-3, including head rod
1, the second connecting rod 2, insulation sleeve 3, support deck 4, fixing body 5, the fixing body 5 are internally provided with support deck 4, and described the
One connecting rod, 1 one end is inserted into inside insulation sleeve 3, and 3 one end of the insulation sleeve is inserted into the inside of the second connecting rod 2, and described
Support card seat 4 is arranged outside one end of two connecting rods 2, the head rod 1 is internally provided with triangle convex 101, and exhausted
Edge set 3 forms interference fit.One end of the head rod 1 is provided with the annular groove 102 for installing support deck 4.Institute
The cylindrical structure that the second connecting rod 2 is narrowing toward each end broad in the middle is stated, and the centre of second connector 2 and both sides are inclined-plane mistake
It crosses.The material of the insulation sleeve 3 is high temperature polymeric materials.The support deck 4 be it is discoid, and the support base 4 with
The interference fit connection of fixing body 5.
Single unit system operation principle is as follows：The technical program passes through, and support deck 4 selects ringent round insulation seat,
It is socketed in the outside of head rod 1.Triangle convex 101 is set outside head rod 1, by head rod 1 and insulation
Set 3 is closely connected in a clamped manner.The utility model has feature simple in structure and convenient and practical.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it still can be with technical scheme described in the above embodiments is modified, or to which part technical characteristic
Equivalent replacement is carried out, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
