Abstract

Electrical connectors are provided with an electrically insulating base member having a connector mounting portion from which at least one pair of mounting lugs extend from an interior surface thereof. A pair of spaced-apart clamp-type connectors, each of which includes a clamp member having a generally U-shaped portion, are provided so as to resiliently engage (and thus mount) an electrical component (e.g., a cylindrical type lamp). The connectors define mounting holes for receiving a respective one of the mounting lugs, whereby the connectors are mounted to said insulating base member. A pair of ribs is provided on the connectors (preferably adjacent the mounting holes) so as to establish a vent space between said connectors and the interior surface of the base member'"'"'s connector mounting portion. The established vent space allows heat generated during use of the electrical component to dissipate.

Claims

1. A clamp-type electrical connector comprising an electrically insulating substrate, and connectors mounted on said insulating substrate, wherein

(a) said electrically insulating substrate includes a connector mounting portion having confronting lugs formed thereon;

(b) said connectors are each integrally provided with (i) a pair of clamping pieces each made of an elastic electrically conductive plate having an electrically conductive base which defines a mounting hole, and (ii) an electrically conductive plug-in connection piece adapted to resiliently engage an electrical component to establish electrical connection therewith;

(c) each of said connectors being mounted on said connector mounting portion by means of said lugs engaging a respective one of said mounting holes defined on the base of said clamping pieces;

(d) said base of each of said clamping pieces also has a pair of raised ribs which contact a surface of said connector mounting portion so as to establish a space between said clamping piece and said surface of said connector mounting portion through which heat generated during use may be vented; and

wherein

(e) an integral side of each of said connectors forms a support piece which is folded back onto a surface of a respective said plug-in connection piece to thereby press against said surface and thereby increase the resilient engagement exerted by said plug-in connection piece against the electrical component.

2. A clamp-type electrical connector as in claim 1, wherein said plug-in connection piece is in the form of a dual side face type contact piece.

3. A clamp-type electrical connector comprising an insulating substrate, and connectors mounted on said insulating substrate, wherein

(a) said insulating substrate includes a connector mounting portion having confronting lugs formed thereon;

(b) said connectors are each integrally provided with a pair of clamping pieces each made of an elastic conductive plate and having a base which defines a mounting hole;

(c) a plug-in connection piece which includes a confronting conductive piece formed by folding a conductive piece which projects from the base of each of said connectors into a U-shape;

(d) each of said connectors being mounted on said connector mounting portion by means of said lugs engaging a respective one of said mounting holes defined on the bases of said clamping pieces; and

wherein

(e) a folded U-shaped side of said conductive piece forms a support piece which presses against the outer surface of said confronting conductive piece.

4. A clamp type connection device according to claim 3 wherein a slit S is defined at substantially the center of said confronting conductive piece.

5. An electrical connector comprising:

an electrically insulating base member having a connector mounting portion which defines an interior surface;

at least one pair of mounting lugs which extend from said interior surface of said connector mounting portion;

a pair of spaced-apart clamp-type electrically conductive connectors each including a clamp member having a generally U-shaped portion for resiliently engaging an electrical component so as to establish electrical connection therebetween, each said electrically conductive connector defining a mounting hole for receiving a respective one of said mounting lugs, whereby said connectors are mounted to said insulating base member; and

vent means for dissipating heat generated during use, said vent means including rib means integrally formed on said pair of connectors and engaging an opposing portion of said interior surface of said insulating base member so as to establish a vent space between said connectors and said interior surface, whereby heat may dissipate therethrough;

wherein each of said connectors includes a plug-in connection piece for receiving an electrical terminal and effecting electrical contact therewith; and

wherein each said plug-in connection piece includes an integral side support piece which is folded back onto said plug-in connection piece to press against an outer surface thereof to thereby increase the resilient engagement which said plug-in connection piece exerts upon the electrical terminal.

6. An electrical connection as in claim 5, wherein each said plug-in connection piece defines a generally centrally located slit.

7. An electrical connector comprising:

an electrically insulating base member having a connector mounting portion; and

a pair of spaced-apart clamp-type electrically conductive connectors mounted to said connector mounting portion of said electrically insulating base member, wherein

each said connector includes a clamp member having a generally U-shaped portion for resiliently engaging an electrical component so as to establish electrical connection therebetween, and a connection piece for receiving an electrical terminal and wherein

each said clamp-type connector includes an integral side support piece which is folded back onto said connection piece to press thereagainst and thereby increase the resilient engagement which said connection piece exerts upon the electrical terminal.

8. An electrical connector as in claim 7, wherein

said connector mounting portion of said electrically insulating base member defines an interior surface having at least one pair of mounting lugs extending therefrom, and wherein

said electrically conductive connectors each define a mounting hole for receiving a respective one of said mounting lugs therewithin, whereby said connectors are mounted to said insulating base member.

9. An electrical connector as in claim 7, wherein said electrical connectors are each provided with a generally centrally located slit.
