The present invention relates generally to apparatuses and methods for horizontally connecting printed circuit boards. Conventional daughter boards are connected to a motherboard in a perpendicular (i.e., vertical) configuration. However, such a configuration limits the size, shape, expansion capabilities, power density, and overall attributes of the motherboard, the daughter board, and any corresponding structure or enclosure. For example, under a conventional configuration, it may be difficult or impossible to provide adequate shielding between the daughter board and motherboard, to provide a grounding layer, or to conform to physical space or power density requirements.
A need exists to provide a low cost method of forming an electrical connection between a printed circuit board and a second printed circuit board located in parallel to one another. A further need exists to provide a method for placing an electrical circuit on a printed circuit board horizontally (e.g., parallel to) above a second printed circuit board to increase the power density of the assembly. An additional need exists for providing a method for placing a shield or ground plane on a printed circuit board placed horizontally above a second printed circuit board. A need also exists for providing a method for placing lands and runs on a small printed circuit board placed horizontally above a second printed circuit board to be used as jumpers on the second printed circuit board.
One embodiment of the present invention provides a horizontal printed circuit board (PCB) holder for connection to a first PCB and a second PCB. The PCB holder may include a frame having one or more legs extending outwardly from the frame, each of the one or more legs having a passageway therein, and at least one conductive pin fixedly secured within the passageway of at least one of the one or more legs. The at least one conductive pin may be configured to convey electrical signals between the first PCB and the second PCB when both of the first PCB and second PCB are connected to the PCB holder.
Another embodiment of the present invention provides a horizontal printed circuit board (PCB) holder assembly. The PCB holder assembly may include a first PCB, a second PCB, and a PCB holder. The PCB holder may comprise a frame having one or more legs extending outwardly from the frame, each of the one or more legs including a passageway therein, and at least one conductive pin fixedly secured within the passageway of at least one of the one or more legs. The at least one conductive pin may be configured to convey electrical signals between the first PCB and the second PCB when both of the first PCB and second PCB are connected to the PCB holder.
A further embodiment of the present invention provides a method of providing a horizontal printed circuit board (PCB) holder having a frame comprising one or more legs extending outwardly from the frame. Each of the one or more legs may include a passageway therein, and at least one conductive pin fixedly secured within the passageway of at least one of the one or more legs for connecting to at least a first PCB and a second PCB. The method may begin by determining at least one characteristic of at least one of the first PCB and the second PCB. The one or more legs of the PCB holder may be configured to correspond to the determined at least one characteristic of at least one of the first PCB and the second PCB. The first PCB may be connected to a first end of the one or more legs of the PCB holder. The second PCB may be connected to a second end of the one or more legs of the PCB holder. Electrical signals may be conveyed between the first PCB and the second PCB via the one or more conductive pins when the first PCB and the second PCB are connected to the PCB holder.

Various embodiments of a holder 100 according to the present invention may be designed to be placed in contact with a first PCB and a second PCB, and to provide electrical connection between the first and second PCBs using conductive pins provided by the holder.
In one exemplary embodiment illustrated by
The one or more legs 120 may be connected to the frame 110 at one or more openings 130. Each of the one or more openings 130 may have a pin 140 passing through a passageway corresponding to at least a portion of the opening 130. The frame 110 may be formed of a conductive and/or non-conductive material. For example, the frame 110 may be formed from a plastic material, a composite material, a metallic conductor, or any other material capable of providing structural rigidity and/or conductivity in accordance with the present invention. Pins 140 may be formed from at least one conductive material. For example, pins 140 may be a metallic pin, for example, made from a conductive metallic alloy, gold, copper, or any other conductive substance capable of conveying signals in accordance with the present invention.
In one embodiment, the opening 130 may extend through leg(s) 120. However, in an alternate embodiment, each leg 120 may include one or more openings 130 which extend into at least a portion of a leg 120 without passing fully through the leg 120. In this example, each leg may include one or more pins 140 connected to one or more opening(s) 130 of leg(s) 120. In embodiments having two or more pins 140 connected to an opening 130, the opening 130 may possess therein a connector and/or electrical conductor (not illustrated) configured to convey electrical signals and/or power between the two or more pins 140.
Each pin 140 may have a first end 142 and a second end 144 located at opposing ends of the pin 140. In one exemplary embodiment, the first end 142 may be associated with a first PCB (e.g., first PCB 210), while the second end 144 may be associated with a second PCB (e.g., second PCB 510). In one exemplary embodiment, each first end 142 and/or second end 144 may be associated with one or more first and second PCBs. For example, a single pin 140 may be configured to pass through one or more first or second PCBs and to provide electrical and/or mechanical connections to each connected first and/or second PCB.
Although illustrated as possessing four sets of legs 120, pins 140, and openings 130, any number of legs 120, pins 140, and/or openings 130 may be used to form a holder 100 within the spirit and scope of the present invention. For example, in one embodiment, a holder 100 may include four legs 120 having four openings 130 housed therein, while the pins 140 used may include only two pins 140. In another embodiment, four pins 140 may be used, but only one pin 140 may form electrical connection to a second PCB while all four pins 140 may be used to form electrical connections to a first PCB (e.g., first PCB 210 illustrated by
The first PCB 210 may include a printed circuit board of a sufficient structural and functional configuration capable of interconnection and operation with a holder 100. For example, the first PCB 210 may include a printed circuit board having one or more functional components which may be interconnected to perform operation(s) in a desired manner. The first PCB 210 may further include one or more connectors 220 configured to receive at least a portion of a pin 140. For example, a connector 220 may be configured as an opening extending through the first PCB 210 which is configured to receive at least a portion of pin 140 (e.g., at a first end 142 as illustrated by
As illustrated, for example, by
Although illustrated in
The first PCB 410 may include one or more connectors 420 configured to receive at least a portion of a pin 340. For example, a connector 420 may be configured as an opening extending through the first PCB 410 which is configured to receive at least a portion of pin 340 (e.g., at a first end 142/342 as illustrated by
As illustrated at
The PCB holder assembly 500 may be configured to convey electrical signals and/or power between the first PCB 410 and second PCB 510 by means of one or more pins 340. In one exemplary embodiment, the PCB holder assembly 500 may be configured to electrically interconnect a larger printed circuit board such as a motherboard and a smaller printed circuit board such as a daughter card, in a parallel configuration. For example, in one exemplary embodiment, the first PCB 410 may include a daughter card and the second PCB may include a motherboard configured to cooperatively function with one another using electrical connections provided by one or more pins 340. Alternatively or in addition to an association between a first PCB 410 and second PCB 510, a plurality of first PCB 410 and/or second PCB 510 may be connected using one or more pins 140/340 of a holder 100/300 or a plurality of holders 100/300 without departing from the scope of the present invention.
As illustrated by
One or more connectors 720 may be connected to one another to form a jumper in an exemplary embodiment. For example, as illustrated at
As is apparent from the previous invention, the shape, size, physical, and logical configurations of one or more PCBs and holder(s) may be determined, modified, adapted, and/or otherwise configured to meet one or more specific desired parameter(s). For example, a holder 100/300 and/or first PCB 210/410 may be designed or otherwise configured to correspond to a shape, pin, jumper, shielding, grounding, or other configuration associated with a printed circuit board (e.g., a second PCB 510). Similarly, a configuration of a second PCB (e.g., second PCB 510) may be determined based upon a characteristic of a holder 100/300 and/or first PCB 210/410. By doing so, the present invention provides for decreased cost relative to conventional PCB connectors, while further providing for reduced size and complexity associated with conventional PCB designs and connectors.
