Brain electrode and electroencephalogram cable connection interface

Abstract

The invention relates to the technical field of medical instruments, in particular to a brain electrode and electroencephalogram cable connection interface. The brain electrode and electroencephalogram cable connection interface comprises an electrode shell and a cable shell, the electrode shell comprises an electrode upper shell and an electrode lower shell, and metal sheets, a first circuit board and a double-row bus are arranged in the electrode upper shell and the electrode lower shell; the cable shell comprises a cable upper shell and a cable lower shell, a second circuit board and a double-row pin are arranged between the cable upper shell and the cable lower shell, the upper end of the double-row pin is inserted and connected into the double-row bus and is connected with the first circuit board, and the two ends of the cable shell are provided with disassembling holes. The brain electrode and electroencephalogram cable connection interface has the characteristic of small structure, can be easily installed and disassembled under the characteristic of small structure, does not damage the bus and the pin after being installed for multiple times, and can achieve the purpose of firm and reliable connection at the same time.

Description

technical field [0001] The invention relates to a connection interface, in particular to a connection interface between brain electrodes and brain electricity cables. Background technique [0002] At present, the brain electrodes and EEG cable interfaces are basically designed as pin headers and female headers. Due to the large number of pins and the small size, there are basically two solutions: [0003] Single row of pin headers: small size, easy to plug in and out, but the pin header is easy to bend, and when the number of pins is large, it needs to be divided into two groups. [0004] Double-row pin and female header: No grouping is required, but the clamping force is relatively large, and the pins are easy to bend when pulled out, so the shell needs to be easy to plug in and out. Usually, it is designed with a pair of handles, and the size is too large. Contents of the invention [0005] The present invention aims to solve the above-mentioned defects, and provides a ...
