Title:
CONNECTION TERMINAL STRUCTURE IN CELL PACK HOUSING CHAMBER FOR SURVEYING INSTRUMENT
Document Type and Number:
Japanese Patent JP3664536
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a cell switch-over circuit from being erroneously operated because of impact caused when each cell pack is housed in the cell pack housing chambers.
SOLUTION: The structure of a connection terminal is formed out of a plurality of cell pack housing chambers provided for a surveying instrument main body, each cell pack 20 which is housed in the cell pack housing chambers respectively, and can be mounted to/demounted from the aforesaid chambers by sliding it back and forth, a contact terminal 28 at the cell pack side, which is exposed at the surface of each cell pack 20, a contact terminal 40 at the surveying instrument side, which is so energized by a spring in the inside of a terminal housing chamber 15 continuously formed in the cell pack housing chambers as to be projected in the cell pack housing chambers in such a way that it can be brought into contact with the contact terminal 28 of each cell pack 20 with pressure so as to be held therein, and of a feed path automatic switch-over control circuit provided for the surveying instrument main body. In this case, an impact absorbing damper 50 for absorbing impact transmitted to the contact terminal 40, is interposed between the terminal housing chamber 15 and the contact terminal 40 at the surveying instrument side.
