<P>PROBLEM TO BE SOLVED: To provide a connection interface device of a photomultiplier tube. <P>SOLUTION: The connection interface device the photomultiplier tube includes a photoelectron multiplying module and a circuit board. A plurality of electric pins are provided on a front end of the photoelectron multiplying module. A plurality of electric contacts are provided on one side face of the circuit board, and the electric contacts are connected with the plurality of electric pins, respectively. An electric connection holder is provided at the periphery at an opposite side of the circuit board, and the electric connection holder is electrically connected with the electric contacts. When making use of the interface device, an known exposure problem of the electric pins of the photomultiplier tube can be improved, an electric connection relationship between a photomultiplier tube and the circuit board can be protected, its destruction is prevented, and noises of high frequency can be reduced. Further, assembling or exchange of the photomultiplier tube and the circuit board can be made more convenient. <P>COPYRIGHT: (C)2009,JPO&INPIT |
