Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of a other elements or its combination.
As shown in figs. 1-11, the present invention provides a kind of pin end 100 with pressure sealing structure, including：Public access headstock,
Pressing plate and connector, wherein：
Public access headstock 140, it is internally provided with the first cavity 150 for storing testing element 130, the public access headstock
First end face on offer the second cavity 160 connected with first cavity 150, in the present embodiment, first cavity
150 and second cavity 160 be coaxial cylindrical cavities, the radical length of second cavity 160 is more than first cavity 150
Radical length be used to place the annular of sealing ring so that second cavity 160 is formed in the periphery of first cavity 150
Bottom, element are placed in the space that the first cavity and the second cavity are formed；
Pressing plate 110, it is sealedly connected in the first end face, and the open end of the second cavity, this implementation are covered with sealing
In example, pressing plate 110 and public access headstock 140 are by screw connection, specifically, the pin end of the second cavity periphery
Offer several threaded holes 141 on seat, it is corresponding on affiliated pressing plate to offer several through holes 111, screw through through hole 111 with
The threaded hole 141 is threadedly coupled, so as to the pressing plate for sealing is fixed in the first end face of the public access headstock, with convenient
Fast Installation and dismounting of the pressing plate with public access headstock 140, it is to be understood that the connection of pressing plate and public access headstock is not limited to use
Screw connection, can also be attached with other known connection modes；It is achieved thereby that a pin end can be replaced not repeatedly
Same element under test, improves the resource utilization of pin end, so as to reduce testing cost；And pressing plate and public access headstock can
To be rapidly assembled and disassembled, testing efficiency is improved；
