Abstract

An electrical assembly of low voltage lamps is disclosed wherein the individual low voltage lamps have rigid lamp leads removably insertable into individual ones of a plurality of electrically conductive socket members which are retained in electrical contact with a pair of electrical wires by virtue of the resiliency of the surrounding insulating covering. The socket members are assembled in pairs to the flexible electrical core by being inserted into the cord cover and into engagement with the electrical wires contained therein by forming a portion of the electrical cord into a curve and penetrating the covering in a marginal area of such curved portion so that the straight configured socket leads penetrate the covering in substantial parallel relationship to adjacent wire portions which are linear. An apparatus for driving a pair of socket members concurrently into engagement with the electrical wires within an insulated covering is disclosed as are exemplary forms of transparent plastic material enclosures for enclosing the assembly of low voltage lamps and flexible electrical cord.

Claims

1. A method of assembling a low voltage lamp to a flexible electrical cord having a pair of flexible electrical conductors lying within a surrounding resilient electrical insulation cover, said method comprising the steps of:

forming said electrical cord into a curved portion with an adjacent straight portion and holding said curved and straight portions stationary;

providing a pair of electrically conductive socket members, each having a rigid socket head with a pointed free end;

positioning said pair of socket members aligned to said cord with each socket lead having its pointed end facing a marginal area of said cord curved portion adjacent said cord straight portion in substantially parallel relation to the extent of said conductors in said cord straight portion;

driving said pair of socket members concurrently into assembled engagement with said cord by pushing said pointed end socket leads through said cover at said marginal area and in between said cover and conductor in said cord straight portion; and

thereafter assembling a low voltage lamp having a pair of lamp leads to said cord by inserting said lamp leads into said socket members.

2. The method of claim 1 including the additional step of:

providing said lamp leads in the form of rigid pins whereby attachment and release of said lamp relative said socket members is facilitated.

3. The method of claim 1 including the additional step of:

providing a translucent tube having an inner diameter larger than the width of said cord and assembled low voltage lamp; and

drawing said cord and low voltage lamp into said tube; and

providing end caps on said tube, at least one of which has a cord aperture to accommodate passage of said cord therethrough.

4. A low voltage lamp and electrical conductor assembly comprising:

a pair of electrically conductive members individually electrically insulated within an electrical insulation cover of resilient material;

an electrically conductive socket member having a rigid socket lead mounted to each of said conductive members by said socket leads being trapped between said cover of resilient material and the associated one of said conductive members;

a single low voltage lamp having a pair of rigid wire lamp leads, each of said lamp leads being removably retained within one of said socket members whereby said lamp is removably assembled in electrical contact with said conductive members.

5. The low voltage lamp and electrical conductor assembly of claim 4 comprising:

an elongated transparent plastic material tube having open ends, said conductive members, cover and lamp lying within said tube; and

removable end caps for closing said tube, at least one of said end covers having an aperture to facilitate running said cover and conductive members therethrough.

6. The low voltage lamp and electrical conductor assembly of claim 5 wherein:

said lamp is laid on its side against said cover within said tube.

7. The low voltage lamp and electrical conductor assembly of claim 4 wherein said assembly includes a plurality of low voltage lamps, each having a pair of rigid wire lamps leads removably retained within one of a plurality of sockets members in said electrically conductive members and

an elongated transparent plastic material tube for enclosing said conductive members and lamps whereby said lamps are visible from all sides of said tube.

8. The low voltage lamp and electrical conductor assembly of claim 7 wherein said tube further comprises:

an upwardly opening channel shaped base of transparent plastic material having upstanding base sidewalls; and

an inverted downwardly opening channel shaped top receivable in said base and having depending resilient walls which engage said base sidewalls by a friction fit of said resilient walls between said base sidewalls.

9. The low voltage lamp and electrical conductor assembly of claim 8 wherein said tube further comprises:

stratiations on portions of said resilient walls facing outwardly thereof to grip against said base sidewalls.

10. The method of claim 7 including the substep of providing said lamp with rigid wire leads.

11. A low voltage lamp and electrical conductor assembly comprising:

an elongated transparent plastic material tube providing visual perception of the interior thereof from all sides thereof;

a pair of electrically conductive members individually electrically insulated within an electrical insulation cover of resilient material extending within said tube; and

a plurality of individual low voltage lamps removably assembled to said members whereby said lamps are visible through said tube from all sides thereof.

12. The low voltage lamp and electrical conductor assembly of claim 11 wherein said tube comprises:

an upwardly opening channel shaped base of transparent plastic material having upstanding base sidewalls; and

an inverted downwardly opening channel shaped top receivable in said base and having depending resilient walls which engage said base sidewalls by a friction fit of said resilient walls between said base sidewalls.

13. The low voltage lamp and electrical conductor assembly of claim 12 wherein said tube comprises:

stratiations on portions of said resilient walls facing outwardly thereof to grip against said base sidewalls.

14. A method of assembling low voltage lamps, each of said lamps having a pair of bare wire leads in easily removable relation to a pair of electrical conductors run within a cover of electrically insulating resilient material comprising the steps of:

providing a plurality of electrically conductive socket members, each having a socket lead for engaging one of said conductors and a socket for removably receiving a wire lead of one of said low voltage lamps;

inserting the socket lead of at least two such socket members through said cover into electrical engagement with said conductors, whereby said two socket members are in generally laterally adjacent relation to and in electrical contact with said two conductors, respectively; and

inserting the wire leads of a low voltage lamp into an adjacent pair of socket members to place said lamp into electrical contact with said conductors.
