Abstract

An electrical connector for connecting a multi-contact medical electrode device with a plural-contact tail. Having a tail-receiving first elongate member with a tail-receiving void and a second elongate member. The second elongate member has a nesting surface and an array of electrical conductors which are spring-loaded pin plunger devices. The spring-loaded pin plunger devices having movable pins that project into the tail-receiving void. The second elongate member also having at least one canopy extending from the nesting surface and over a respective electrical conductor, the canopy being configured for snap-engagement with the notch whereby the canopy holds in place the respective linear-array plural-contact tail through locking frictional engagement.

Claims

1. In an electrical connector for connecting a linear-array plural-contact tail of an in-body multi-contact medical electrode device, including (a) a tail-receiving first elongate member having proximal and distal ends, the first elongate member forming a tail-receiving void and having a presentation face which is parallel to the void and has notches therealong intersecting with the void to expose the plural tail contacts in the void and (b) a second elongate member with corresponding proximal and distal ends and having a nesting surface and an array of electrical conductors therealong, the improvement comprising at least one canopy extending from the nesting surface of the second elongate member and over a respective electrical conductor, the canopy being configured for snap-engagement with the notch whereby the canopy holds in place the linear-array plural-contact tail through locking frictional engagement.

2. The multi-contact medical connector of claim 1 wherein:

the nesting surface includes a pivot-axis-adjacent face and a pivot-axis-opposite face substantially perpendicular thereto; and

the presentation face is substantially parallel to the pivot-axis-opposite face when the first elongate member is in the closed position.

3. The multi-contact medical connector of claim 1 wherein each canopy is/are fixed to the pivot-axis-opposite face.

4. The multi-contact medical connector of claim 1 wherein each canopy is/are integrally formed with the pivot-axis-opposite face.

5. The multi-contact medical connector of claim 1 wherein each canopy partially encircle(s) a respective one of the electrical conductors.

6. The multi-contact medical connector of claim 1 wherein:

the electrical conductors are pin plunger devices which protrude beyond the nesting surface toward the first elongate member;

the presentation face and the nesting surface abut one another to define the closed position;

the presentation face has a lead edge which is adjacent to the nesting surface when the first elongate member is in the closed position; and

the notches on the presentation face extend to the lead edge such that the notches receive the pin plunder devices and engage the at least one canopy as the first elongate member is pivoted to the closed position.

7. In combination, (a) an electrical connector comprising a tail-receiving first elongate member with an presentation face and an elongate void with the plural-contact tail received therein, the first elongate member also having a lead edge with notches therealong intersecting with the void to expose the plural tail contacts, and a second elongate member having a nesting surface and an array of spring-loaded pin plunger devices therealong and (b) a linear-array plural-contact tail inserted within the void, the improvement comprising at least one canopy-extending from the nesting surface of the second elongate member and over a respective pin, plunger device, the canopy being configured for snap-engagement with the notch whereby the canopy holds in place the respective linear-array plural-contact tail through locking frictional engagement.

8. The multi-contact medical connector of claim 7 wherein:

the nesting surface includes a pivot-axis-adjacent face and a pivot-axis-opposite face substantially perpendicular thereto; and

the presentation face is substantially parallel to the pivot-axis-opposite face when the first elongate member is in the closed position.

9. The multi-contact medical connector of claim 7 wherein each canopy is/are fixed to the pivot-axis-opposite face.

10. The multi-contact medical connector of claim 7 wherein each canopy is/are integrally formed with the pivot-axis-opposite face.

11. The multi-contact medical connector of claim 7 wherein each canopy partially encircle(s) a respective one of the electrical conductors.

12. The multi-contact medical connector of claim 7 wherein:

the pin plunger devices protrude beyond the nesting surface toward the first elongate member;

the presentation face and the nesting surface abut one another to define the closed position;

the presentation face has a lead edge which is adjacent to the nesting surface when the first elongate member is in the closed position; and

the notches on the presentation face extend to the lead edge such that the notches receive the pin plunger devices and engage the at least one canopy as the first elongate member is pivoted to the closed position.
