Description
Technical field
The utility model is related to a kind of welder, more particularly, to a kind of effective welder of photomultiplier transit.
Background technology
Photomultiplier is low-light-level measurement, particularly the important devices of limit faint light detection technology.In life science, core
The high-tech areas such as physical technique, nuclear medicine, biochemistry, rigorous analysis, information science, environmental monitoring, industry automatic control
In, photomultiplier has extremely important application.The signal that it is exported is very sensitive, this requires two signal amplification circuit plates
The testing efficiency of photomultiplier in strict conformity with given size, otherwise must can be influenced with the welding distance of its tail end, and then is influenced
The accuracy of sample tests.
Traditional welding method is estimated by welder, mobile first signal amplification circuit plate and photomultiplier
Tail end when being of the required size, circuit board and pipe pin are welded together.Complete the welding of first signal amplification circuit plate
Afterwards, then move the range estimation of second signal amplification circuit plate and the tail end of photomultiplier is of the required size, weld again, finally
Complete the assemble welding of two block signal magnification circuit plates and photomultiplier.Traditional welding method manual operation error is larger,
Inefficiency, and it is very big with the photomultiplier error in length of model, it is difficult to ensure that signal amplification circuit plate is welded with its pipe pin
Connect the batch uniformity of position.
Utility model content
The utility model is to solve to lead since the photomultiplier length tolerance of model of the same race is excessive in the prior art
It causes the signal amplification circuit plate of its tail end and its pipe silk welding position cannot be guaranteed deficiency in given size, provide a kind of light
The effective welder of electricity multiplication.
A kind of effective welder of photomultiplier transit of the utility model, including pedestal, middle cylinder, cheese head screw, upper cover, under
Lid, sunk screw；Raised stepped outer surface is threaded on the pedestal；The inner surface of the middle cylinder is threaded；It is described
Pedestal and middle cylinder are installed together by corresponding thread fitting, and cylinder threadingly moves up and down in realization；The photomultiplier dress
Enter in cylinder, photomultiplier front end face is contacted with base boss upper surface；The lower cover is fixed with middle cylinder by sunk screw
Together, rotating base makes middle cylinder threadingly vertically move, and the breech face and lower cover end face for making photomultiplier are in close contact.
Preferably, the pedestal, middle cylinder, upper cover, lower cover must use insulating materials.
The utility model has the advantages that：It is simple in structure, easy to operate, it can be widely applied to due to photomultiplier
Length tolerance is excessive, signal amplification circuit plate and its pipe silk welding position is also can guarantee in defined size, for different length
Photomultiplier, it is ensured that the accuracy of signal amplification circuit plate and its breech face size improves worker's welding job efficiency.
The signal amplification circuit plate of photomultiplier tail end and the position dimension of its pipe pin welding can be effectively ensured.

In figure：Pedestal 1, middle cylinder 2, cheese head screw 3, upper cover 4, lower cover 5, sunk screw 6, photomultiplier 7, circuit board one
8th, circuit board 29, stepped outer surface A raised on pedestal 1, inner surface B, base boss upper surface C, the photomultiplier transit of middle cylinder 2
The breech face D of pipe, the pipe silk E of photomultiplier.
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and detailed description.
Such as Fig. 1, a kind of effective welder of photomultiplier transit, including pedestal 1, middle cylinder 2, cheese head screw 3, upper cover 4, lower cover 5,
Sunk screw 6 forms.Even if photomultiplier length tolerance is excessive, which can still ensure signal amplification circuit plate and its
Pipe silk welding position is in specified value.
Such as Fig. 2, in order to adapt to the different height of photomultiplier 7, it is necessary to which stepped outer surface A raised on pedestal 1 is set
It counts into and is threaded.
Such as Fig. 3, in order to adapt to the different height of photomultiplier 7, it is necessary to which the inner surface B of middle cylinder 2 is designed with spiral shell
Line.
Such as Fig. 4, in order to which cylinder 2 threadingly moves up and down in realizing, pedestal 1 and middle cylinder 2 pass through corresponding thread fitting and install.
Such as Fig. 5, in order to ensure that the tail end D of circuit board 1 and photomultiplier 7 apart from size is specified value, first by photoelectricity
During multiplier tube 7 is fitted into cylinder 2, front end face is contacted with the boss upper surface C of pedestal 1；Lower cover 5 passes through sunk screw 6 with middle cylinder 2
It is fixed together, rotating base 1 makes middle cylinder 2 threadingly vertically move, and ensures the tail end D faces of photomultiplier 7 and the end of lower cover 5
Face is in close contact；The pipe silk E of circuit board 1 through photomultiplier 7 falls in the concave station of lower cover 5, at this time welds pipe silk E
On circuit board 1.
Such as Fig. 6, in order to ensure that circuit board 29 with circuit board 1 is specified value apart from size, by upper cover 4 and lower cover 5
It is fixed together by cheese head screw 3；The pipe silk E of circuit board 29 through photomultiplier 7 falls in the concave station of upper cover 4, this
When pipe silk E is welded on circuit board 29.
Certainly, the utility model can also have other embodiment, on the premise of without prejudice to the utility model in essence, related skill
Art personnel can make corresponding change or deformation according to the utility model, but these change and deformation should all belong to the utility model power
The protection domain of profit requirement.
