An electrical brain-contact device and device for connecting a plurality of lead wires with individual conductors. The lead wires extend to a terminal mount and to an array of terminals; a conductor support holds an array of the individual conductors; and a connector block with a first space and an array of second spaces serves to join the conductors to the terminals, preferably by a biasing means. The first space receives the terminal mount and the array of second spaces receives the conductor array. The block may be single or have a plurality of sub-blocks attached end-to-end allowing the block to be sized to accept any number of terminals and conductors. Each block or sub-block is preferably a non-conductive one-piece member.

DETAILED DESCRIPTION The parent applications referred to above describe certain advances which have been made toward avoiding or minimizing the above problems.
This invention described herein represents a further improvement, overcoming or minimizing such problems.
The invention is an improvement in electrical devices for brain contact of the type having a tissue-engagement member with a plurality of electrodes, separate lead wires from the tissue-engagement member for each electrode, and means away from the tissue-engagement member to connect the lead wires with individual conductors, such as conductors leading to equipment for recording of electrical impulses.
More generally, this invention is an improved electrical connection device of the type for connecting a plurality of lead wires with individual conductors.
In the device of this invention, the lead wires extend to a terminal mount and to an array of lead-wire terminals on and forming a part of the terminal mount.
A conductor support holds the individual conductors in a conductor array.
A connector block, hereafter described, serves to join the lead-wire terminals to the individual conductors and hold them firmly in engagement.
The connector block has a first space and an array of second spaces each of which intersect the first space.
The first space receives the terminal mount and the array of second spaces receives the conductor array.
Broadly described, the connector block, terminal mount and conductor array are configured and arranged such that the lead-wire terminals and individual conductors are held in engagement by mechanical interference.
In preferred embodiments of this invention, the terminal mount is an elongate member having the lead-wire terminals spaced therealong.
For example, the terminal mount may include a tubular sheathing covering all the lead wires and rings around and spaced along the sheathing forming the lead-wire terminals.
In such cases, the first space in the connector block may be a first elongate cavity in the connector block formed of non-conductive material and shaped to receive the elongate member
