Abstract

An electrical connector is used in combination with an electrical circuit board having an active element and formed with a row of throughgoing contact holes and a multiconductor cable having a plurality of wires each having a core conductor. The connector has a dielectric body formed with a row of parallel and outwardly open contact seats, a row of parallel and outwardly open wire seats aligned with and extending transversely across the contact seats, and an outwardly open pocket traversed by the contact seats and dimensioned to hold the circuit board with its holes aligned with the contact seats. Respective contacts in the contact seats each have a pointed tip engaged through the respective hole of the board in the seat and poking in the respective wire seat into the respective wire and into contact with the conductor thereof.

Claims

1. In combination with

an electrical circuit board having an active element and formed with a row of throughgoing contact holes, and

a multiconductor cable having a plurality of wires each having a core conductor,

an electrical connector comprising:

a dielectric body formed with

a row of parallel and outwardly open contact seats,

a row of parallel and outwardly open wire seats aligned with and extending transversely across the contact seats, and

an outwardly open pocket traversed by the contact seats and dimensioned to hold the circuit board with its holes aligned with the contact seats; and

respective contacts in the contact seats and each having a pointed tip engaged through the respective hole of the board in the seat and poking in the respective wire seat into the respective wire and into contact with the conductor thereof, the contacts being movable from an outer position with their tips outward of the pocket and conductor seats and an inner position with their tips in the conductor seats.

2. The electrical connector defined in claim 1 wherein the body has a connector part formed with the contact seats and a grip part formed with the pocket and conductor seats.

3. The electrical connector defined in claim 1 wherein the circuit-board holes are conductively lined and the contacts have portions adjacent their tips in electrical contact with the respective holes.

4. The electrical connector defined in claim 3 wherein the contact portions are widened and bear laterally elastically on the respective lined holes.

5. The electrical connector defined in claim 1 wherein the body is further formed with a large-diameter seat dimensioned to loosely receive the cable and into which the conductor seats open.

6. The electrical connector defined in claim 5 wherein the conductor seats have outwardly flared ends at the large-diameter seat.

7. The electrical connector defined in claim 1, further comprising

a mass of thermoplastic filling the pocket around the circuit board, the cable being imbedded in the mass also.

8. The electrical connector defined in claim 7 wherein the active element is a light-emitting diode and the mass is at least limitedly transparent.

9. The electrical connector defined in claim 7 wherein the body is further formed with a large-diameter seat dimensioned to loosely receive the cable and into which the conductor seats open, the mass filling the large-diameter seat around the cable.
