[0010] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. The aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.

[0011] This disclosure is generally drawn, inter alia, to methods, apparatus, systems and / or devices related to providing various structures for solderless bussing contacts for multi-pin connector systems.

[0012] FIG. 1 illustrates perspective viewsx>f an example pair of a circular connector systems with multiple contacts, where solderless bussing contacts may be implemented, arranged in accordance with at least some embodiments described herein.

[0013] Diagram 100 shows a receptacle 102 with contact pins 104. In an example implementation, a ground contact 106 may be in cavity “A” and a standard pin. The other cavities may include shorter contacts. Diagram 100 also shows a plug 108 with socket contacts 110. In some examples, the plug 108 and the receptacle 102 may be used to deliver power to electronic devices and may cany high currents. Thus, the connections between the contacts (pins and sockets) and respective wires may need to accommodate high currents. In some examples, the connectors may or may not include spacers. Diagram 100 shows receptacle 102 without a spacer and plug 108 with a spacer 112.

[0014] The plug 108 and the receptacle 102 are shown with 7 contacts (pins and sockets) and have a circular shape as an illustrative example. Embodiments are not limited to a specific number of contacts and / or shape or size of connector system. Any number of pins and any shape of connectors may be implemented with soideriess bussing contacts using the principles described herein.

[0015] FIG. 2A and 2B illustrate a multiple solderless bussed contact circular connector system with a spacer, arranged in accordance with at least some embodiments described herein.

[0016] Diagram 200A shows a front view of a 7 -contact circular receptacle connector with contact pins 210 in respective connector cavities. In the illustrated configuration, a ground contact p[in 206 is in a separate cavity 208. The contact cavities are within a connector insulator (not shown) surrounded by a shield 204, all within the connector shell 202, In some examples, a spacer 222 may be used. Diagram 200B shows a perspective view of a plug connector with socket contacts and the spacer 222.

[0017] FIG. 2C illustrates bussing configurations in a circular connector, arranged in accordance with at least some embodiments described herein. Diagram 200C shows a 7-contact circular connector configuration with six signal contacts (B through F) 210 and buss paths 212 between the contacts. A seventh contact (A) 208 is a dedicated ground contact. Any two or moresignal contacts (B through F) may be electrically connected through a busbar of a contact on the buss path(s). For example, a pin or socket may include a single, dual, triple, or more connection busbar. The busbar may enable that pin or socket to distribute its signal (i.e., power) over two or more contacts allowing higher currents to be carried by the connector.

[0018] Bussed connectors are designed for use in heavy duty applications, where multiple circuits may require a common electrical pathway. A busbar, or buss, is a thin conductive strip connecting two or more contacts of the connector within the body of a connector. As shown in the diagram 200C, the number of contacts in a connector (or any size dr shape) may be reduced through bussing. The contacts to be coupled together (electrically) may be selected based on application requirements, symmetry, spacing, or other considerations.

[0019] FIG. 3A through 3C illustrate 3-, 4-, and 5-wire bussing configurations with and without spacers in a circular connector, arranged in accordance with at least some embodiments described herein.

[0020] Diagram 300A shows top and perspective views of a 3-wire bussed connector, where a pair of three contacts (C-D-E and B-F-G) 304 are each bussed together to two contacts 306, 308. Thus, the connector has two signal contacts 306, 308 (carrying current) and a ground contact (A) 302.

[0021] Diagram 300B shows top and perspective views of a 4-wire bussed connector, where three pairs of two contacts (E-F, D-G, and B-C) 314 are each bussed together to three contacts 316, 318, and 320. Thus, the connector has three signal contacts 316, 318, 320 (carrying current) and a ground contact (A) 312.

[0022] Diagram 300C shows top and perspective views of a 5-wire bussed connector, where three single contacts (B, F, G) 324 are each coupled to a single signal contact (socket or pin) and three contacts (C-D-E) 326 are bussed together to another single signal contact. Thus, the connector has four signal contacts 328 (carrying current) and a ground contact (A) 322,

[0023] While diagrams 300A through 300C show various configurations with specific contacts being bussed together, solderless bussed connectors may be implemented with other configurations using the principles described herein. Any two or more contacts may be selected to be bussed together depending on desired total wire number, wire size, spacing requirements, etc.

[0024] FIG. 4 illustrates a spacer for a multiple solderless bussed contact circular connector system, arranged in accordance with at least some embodiments described herein.

[0025] Diagram 400 shows a dielectric spacer with through-holes (A through G) 402 for the contactsand buss paths 404 between the through-holes. Buss paths 404 are recesses on a wire side of the spacer to receive busbars for bussed contacts. The busbars, as discussed herein, may connect two or more contacts in a variety of configurations. Thus, the buss paths 404 form a mesh that can accept any configuration bussed contact(s).

[0026] FIG. 5A illustrates a perspective partial assembly view of a circular bussed connector with busbar contact and crimp terminal lugs, arranged in accordance with at least some embodiments described herein.

As mentioned herein, the dielectric spacer 504 may include through-holes and recesses arranged to accept different configurations of busbar pins and contacts. Thus, the connector may be reconfigured without complete replacement or configured easily using generic templates at manufacturing. Crimp terminal lugs 502 may be fastened to the busbar contacts through a removable fastening mechanism such as screws, a clip-on mechanism, a push-on mechanism, or similar ones. Thus, another degree of configurability for the connector is its wire sizes. Crimp terminal lugs 502 may be replaced with larger or smaller size ones without changing toe dielectric spacer or the busbars allowing larger or smaller wire size configurations (depending on carried current) to be used with toe connector. In example implementations, wire sizes between #4 AWG and #10 AWG may be supported, as well as others.

Hie coupling ring 526 may coupled the connector shell 510 and a back shell (not shown) covering the busbar contacts and crimp terminal lugs 502. In some examples, the back shell may be a universal back shell for use with any size and number crimp terminal lugs. Individual wires may be affixed inside toe crimp terminal lugs through push pins 524. Thus, a connector according to examples may avoid any use of solder with all couplingsbeing accomplished mechanically. The connector shell, coupling ring, and back shell may be made from an aluminum alloy, a tin-zinc-nickel alloy, or from a ceramic or plastic and have a conductive finish (e.g., plating). The spacer, connector insulator may be made from a thermoplastic, or other dielectric material.
