Description
Technical field
The present invention relates to the mounting means of the prime amplifier module of neutron detector, particularly a kind ofly be used to reinforce the device that the neutron detector housing is connected with the prime amplifier module.
Background technology
In the X-ray detection X field, neutron detector and its prime amplifier module adopt concentric cable to be connected to each other by a pair of coaxial fitting usually, or connect firmly mechanically.Because ray detector is highly sensitive quasi-instrument, often owing to reasons such as poor electric contact, electromagnetic interference (EMI), vibrations, makes nonpassage of signal or be interfered, thereby influence sensitivity, accuracy and the degree of stability of instrument.Do not have the unified standardized detector and the coupling scheme of its prime amplifier at present both at home and abroad, but carry out concrete Coupling Design according to concrete detector and prime amplifier.When adopting common coaxial fitting connected mode, because the intrinsic position of prime amplifier module joint is eccentric and the structural limitations of joint itself, module exists the phenomenon that relatively rotates and become flexible with detector after being connected, influence the reliability of equipment.
Summary of the invention
Relatively rotate and become flexible problem in order to solve prime amplifier module after the connection and neutron detector, the invention provides a L shaped bent plate, one end of bent plate utilizes that original screw retention is on module on the module, and the other end of bent plate utilizes screw retention on detector housing.
Therefore, technical scheme of the present invention is:
A kind ofly be used to reinforce the device that the neutron detector housing is connected with the prime amplifier module,
This neutron detector housing and this prime amplifier module are docked mutually by a coaxial fitting of stretching out from separately apparent surface, and realize this triangular screw-thread securing by rotating an attaching nut who covers on this a pair of cable splice outside,
It is characterized in that,
This bracing means comprises a bent plate, this bent plate has orthogonal first (2a) and the second portion (2b) that is the L type profile, at least comprise two through holes in this first (2a), being used for respectively being on the surface with this prime amplifier module on the horizontal line original corresponding screw aims at, so that utilize screw that this first (2a) is fixed on this surface of this prime amplifier module
At least comprise a through hole on this second portion (2b), be used for aiming at a lip-deep corresponding screw of this neutron detector housing, so that utilize screw that this second portion (2b) is fixed on this surface of this neutron detector housing, thereby prevent that the screw-thread securing between these two cable splices and this attaching nut from taking place loosening.
Beneficial effect:
Compare with prior art, the present invention has realized the good coupling and the electromagnetic screen of neutron detector and its prime amplifier module, avoids between detector and its prime amplifier causing poor electric contact, being subject to the shortcoming of external electromagnetic interference because of reasons such as vibrations, rotations; Be easy to simultaneously machinery assembling and daily servicing again.This technology is applicable to neutron, gamma and X ray detection instrument exploitation manufacturing technology field.

Fig. 2 is the top view of the device of Fig. 1;
Fig. 3 is the side view of the device of Fig. 1.
Embodiment
Be described in detail a specific embodiment of the present invention below in conjunction with accompanying drawing.From Fig. 1,2,3 as seen, the 3rd, prime amplifier module, the 5th, neutron detector housing.In addition, 4 among the figure is columnar attaching nuts, and it entangles the cable splice 8 that protrudes on the cable splice 7 that protrudes on the prime amplifier module 3 and the neutron detector shell 5 simultaneously in when work.By rotating this attaching nut 4,, make these two cable splices rely on this attaching nut and be docking together by the threaded engagement between this three.Detector and prime amplifier is connected and fixed form in the prior art that Here it is.In addition, the 1st, one of original screw on the surface of prime amplifier module 3.As can be seen from Figure 1, on this surface of prime amplifier module 3, dispose 4 same screws symmetrically.These original screws just in time can be utilized by bracing means of the present invention.Bracing means of the present invention mainly comprises a bent plate, and this bent plate has the 2a of first and the second portion 2b of the orthogonal L of being type profile.On the 2a of this first, dispose 2 through holes at least, their are aimed on this surface of prime amplifier module be in original two screws on same the horizontal line, so that when the 2a of this first is pressed close to this surface, screw can be passed in lip-deep this screw that these two through holes are screwed into this module 3, thereby the 2a of this first is fixed on the prime amplifier module.
In addition, as shown in figs. 1 and 3, the height of the 2a of this first can very easily be designed to when the 2a of this first and prime amplifier module in a manner described fixedly the time, and the second portion 2b of this bent plate just in time is flattened on neutron detector 5 to have on that plane surface of cable splice of protrusion.Suitably dispose at least one through hole 6 on the second portion 2b of bent plate of the present invention, therefore, as long as with through hole 6 over against this surface location of neutron detector shell 5 dispose corresponding screw, screw is passed the described lip-deep screw that through hole 6 on the second portion 2b of bent plate screws in neutron detector shells 5, just can realize being connected between bent plate of the present invention and the neutron detector.Like this, bent plate of the present invention just is securely fixed in amplifier module 3 on the neutron detector shell 5, thus existing connection and fixedly play highly effective reinforcement effect between the coaxial fitting to them.
For the 2a of first that makes bent plate does not hinder attaching nut 4 dismounting, the shape of the 2a of this first can suitably be designed.For example, it is designed to as shown in accompanying drawing 1 do not hinder people to see intuitively from the front and near the shape of attaching nut and cable splice.Obviously, its actual shape can be diversified.In addition, at least two through holes on the 2a of first of bent plate and at least one through hole on the second portion 2b can be slotted holes, so that compensate the foozle of each correlated parts.
The those of ordinary skill of art technology can understand that above embodiment only is an illustrative, according to design of the present invention, can implement in many ways fully.
