Abstract

A low-cost electrical connector assembly (1) comprises a socket subassembly (12) removably attached to a distribution subassembly (10) in predetermined inter-position. The distribution subassembly (10) includes a bus housing (8) accommodating and retaining distribution blade buses (2, 3, 4) in predetermined positions, and a bus housing cover (9) removably secured on the bus housing (8) for further supporting and retaining said distribution blade buses (2, 3, 4). The socket subassembly (12) includes a socket housing (11) retaining socket buses (5, 6, 7) in predetermined positions. Each distribution blade bus (2, 3, 4) includes a connection end (22) and a terminal end (23), respectively, and formed from an integral metal bus strip which is folded to fit into the respective predetermined compartments (19) in the bus housing (8). Each socket bus (5, 7) includes respective spaced apart parallel slits (47, 49), and the socket bus (6) includes spaced apart parallel slits (47, 48), wherein the slits (47 ) serve for receiving the connection end (22) of the respective distribution blade busses (2, 3, 4) and the slits (48, 49) serve for receiving entry terminals of equipment to be powered.

Claims

1. A connector assembly comprising:

a socket subassembly removably attached to a distribution subassembly in predetermined interposition;

said distribution subassembly including a bus housing accommodating and retaining distribution blade buses in respective predetermined pathways, and a bus housing cover secured to the bus housing and providing means for further supporting and retaining said distribution blade buses within the bus housing;

said socket subassembly including a socket housing retaining socket buses in predetermined positions;

each of said distribution blade buses comprising an integral metal bus strip having a substantial uniform width, each of said bus strips includes a connection end and a terminal end, respectively, at least one said bus strip being folded across its width to define first and second portions on respective sides of said fold extending to respective ones of said connection and terminal ends, the first and second portions extending in different directions complementary to a said respective predetermined pathway for said bus strip in the bus housing; and

each of said socket buses comprising an integral metal socket strip, respectively, each socket strip having a respective first opening for receiving the connection end of the respective bus strip, thereby providing electrical connection of each socket bus to the respective distribution blade bus.

2. The connector assembly according to claim 1, wherein said distribution blade buses include hot, ground and neutral distribution buses, respectively, wherein said socket buses include hot, ground and neutral socket buses, respectively, and wherein the bus housing provides respective slots through which the terminal ends of the hot, the ground and the neutral distribution buses protrude for plugging into a power supply.

3. The connector assembly according to claim 1, wherein the socket housing further includes molded internal walls defining respective compartments for receiving the respective socket buses and retaining the respective socket buses in the predetermined positions.

4. The connector assembly according to claim 1, wherein the bus housing further includes respective internal walls defining respective compartments for receiving the respective distribution blade buses in predetermined order and retaining the respective distribution blade buses in the predetermined positions.

5. The connector assembly according to claim 1, wherein each of the socket buses further includes a second and a third opening for receiving entry terminals of equipment to be powered, said second and the third openings being in juxtaposition with the first opening, and wherein the respective first, second and third openings in the socket strips comprise respective slits.

6. The connector assembly according to claim 1, wherein each distribution blade bus further includes a central portion connecting the connection end and the terminal end at a right angle to each other.

7. The connector assembly according to claim 1, further including a faceplate removably attached to the socket housing.

22. A connector assembly of claim 1 wherein said at least one bus strip includes a second fold at a second selected location to define a transverse portion intermediate said folds whereby said connection and terminal ends are mutually offset from each other.

8. An electrical connector comprising distribution blade buses and socket buses, wherein each of the distribution blade buses includes a metal strip having a substantially uniform width, each said bus strip being folded across its width at two locations therealong to define a transverse portion therebetween at a selected location intermediate a connection end and a terminal end, wherein the connection end and the terminal end are integrally connected and mutually offset from one another, and extend in parallel directions complementary to a respective predetermined pathway for said bus strip in the bus housing and wherein each of socket buses includes a metal strip having a respective first slit for removably receiving the connection end of the respective distribution blade bus.

9. The electrical connector of claim 8, wherein each of socket buses includes a second and a third spaced-apart slits, and wherein said second and third slits are juxtapositioned and parallel to the first slit.

10. The electrical connector of claim 9, wherein each distribution blade bus is formed and wherein the first, second and the third slits in the socket bus are lanced out such that no material is scrapped.

11. A method of assembling a connector assembly including the steps of:

providing a bus housing having a plurality of internal walls defining respective compartments for accommodating distribution blade buses;

providing distribution blade buses, each distribution blade bus being formed from a metal strip and formed to provide a connection end, a terminal end and a central portion integrally connecting the connection end and the terminal end at a right angle to each other;

positioning the distribution blade buses into respective compartments of the bus housing in predetermined order;

providing a bus housing cover;

securing the bus housing cover to the bus housing, thereby forming a distribution subassembly;

providing a socket housing, the socket housing having a plurality of internal walls defining compartments for accommodating respective socket buses;

providing socket buses, each socket bus being formed from a metal bus strip and lanced out to provide a first, a second and a third spaced-apart parallel slits, wherein the first slits are for receiving the connection end of the respective distribution blade bus, and wherein the second and the third slits are for receiving respective entry terminals of equipment to be powered;

positioning the socket buses into respective compartments of the socket housing; and

securing the socket housing to the distribution subassembly with the respective connection ends of the respective distribution blade buses received within the respective first slits.

12. The method according to claim 11, wherein the bus housing cover is snapped into the bus housing.

13. The method according to claim 11, wherein the bus housing cover is heat staked with the bus housing.

14. An electrical device including a bus formed from a metal strip and at least one input blade, the bus including a plurality of sockets, each defined by a slit extending longitudinally along a portion of the bus and a portion of the bus adjacent the slit extending transversely of the bus, at least one of the sockets being configured to receive the input blade configured for connection to a source of electricity and at least one of the sockets being configured to receive an output blade from a second electrical device.

15. The electrical device of claim 14, wherein each socket is formed by at least two portions of the bus on opposite sides of the slit, the two portions of the bus extending in opposite transverse directions.
