The present disclosure generally relates to connector assemblies, and particularly connector assemblies, including straight and right-angle housings, center contacts, and printed circuit boards.
Some microwave frequency connectors have housings and metallic center contacts that are designed to be soldered directly to a printed circuit board (PCB). The metallic center contacts are generally surrounded by a plastic insulator and the metallic housing. Socket contacts in these connector assemblies are key components in the transmission of electrical signal. The components in connectors may be coupled by various methods, including a push-on design. These types of connectors may use a cable interconnect to transmit the signal to the PCB. However, these types of interconnections usually perform poorly above 10 GHz due to a right-angle transition to the PCB.
There are also connectors that include a housing and a metallic center contact that engages with a cable. The metallic center contact in the cable connector is generally surrounded by a plastic insulator and the metallic housing. The cable in the right-angle housing may be engaged, for example, by soldering a metallic access contact to a center conductor of the cable and then inserting the metallic access contact and cable subassembly into the right-angle housing. The metallic access center contact may thereafter be mated with a socket center contact within the right-angle housing. Another method to engage the cable is to simply insert the prepared cable into the housing where the center conductor of the cable directly engages the socket center contact in the right housing. In both cases the cable may be soldered to the housing. This type of design performs well up to 50 GHz depending on the specification of the cable.
Despite these various methods, there is still a need for solderless center contacts that mate to a PCB, using both solderless center contacts and solderless ground housings at high frequencies with low signal losses. In addition, there is a need to address the aforementioned interconnection situations in unique applications to improve performance at high frequencies, reduce discontinuities, and simplify the transition between PCBs.
Embodiments disclosed herein are directed to connector assemblies, including low and high frequency connectors and DC connectors designed for low level signals. Some embodiments, however, are configured to operate at high frequencies, including frequencies up to 65 GHz, with low insertion and return losses.
The connector assemblies include a conductive housing, one or more dielectrics, and conductors, some of which may be configured as compressible electrical contacts. Each compressible electrical contact is configured to vary its length, compensate for tolerance ranges/deviations of mating center conductors or cables, and maintain constant electrical/mechanical connection upon assembly. The properties of the compressible electrical contacts disclosed herein are due, in part, to manufacturing the contacts using precision cutting methods, which result in a plurality of cut sections. Such methods include, but are not limited to, laser cutting, electroforming, and/or electro-etching. Regardless of the precision cutting method used, the contacts disclosed herein are preferably designed, using divaricating patterns, such that each contact has a plurality of cut sections in its final form.
The term “divaricating pattern”, as used herein, is defined as a cutting pattern that allows the compressible electrical contact to have contact sections configured to form open tapered areas after cutting when in a substantially relaxed state, nest or collapse inwardly to form outwardly extended tapered slots when compressive force is applied to ends of the compressible electrical contact, resulting in a substantially compressed state. The contacts are also configured maintain a flexible and substantially tubular form when transitioning from a substantially relaxed state to a substantially compressed state, despite the presence of the plurality of cut sections.
In some embodiments of the connector assemblies, the dielectrics contained therein are configured to guide one or more conductive center conductors, which functions as a signal conductor, through an angle ranging from about a 0° to about a 90°, which transition to a printed circuit board (PCB). The connector assemblies disclosed herein also preferably have a very low a profile and may be used in compact connector-PCB assemblies.

In the substantially relaxed state, shown in
DAC1 measures the overall height of the theoretical divaricated cut 3050A. EAC1 measures the FAC1, and GAC1. EAC1 measures the distance of the center of the divaricating pattern PA from a first outer edge 3026A of the tube 3000A. FAC1 is the widest width of the divaricating pattern PAT1 and GAC1 is narrowest width of the divaricating pattern PT1.
A theoretical cut 3060A for a tube medial portion 3030A may be defined with respect to a second divaricating pattern PAT2, using predefined measurements DAC2, FAC2, and GAC2. DAC2 measures the overall height of the theoretical cut 3060A. FAC2 is the widest width of the divaricating pattern PAT2 and GAc2 is narrowest width of the divaricating pattern PAT2. The divaricating patterns PAT1, PAT2 are further defined with respect to dimensions HAc, DAm, where HAc is the distance between the patterns PAT1, PAT2 measured from their respective centerlines and DAM1 is the distance from the bottom of divaricating pattern PAT2 to a middle line ML where the tapered sections 3070A1, 3072A1 join, with the line being central axis CA.
The theoretical cuts are further defined with respect to each other at a measurement HAc defined with respect to the centerlines of theoretical end cut 350A and theoretical medial cut 360A. Preferably, the divaricating patterns are such that they allow the final form of the cut compressible electrical contact to exhibit spring-like properties. Moreover, in the embodiments disclosed herein, zig-zag-like tapered patterns are preferred such that the final properties of the contact are spring-like. The divaricating pattern PA is also configured such that the amount of bowing that could occur in the medial portion, after cutting of the tube and during compression is minimal. Alternative variations and divaricating patterns may, however, be used.
In the substantially relaxed state, the compressible electrical contact 2600 has a relaxed length defined as LR2, measured from a first outer edge 2626a to an opposing outer edge 2628a. Contact end 210 is defined, in part, by a bottom length, BLDE1 measured from the outer edge 2626a to a bottom inner edge 2626b. Contact end 2620 is defined, in part, by a top length, TLDE1 measured from the outer edge 2628a to a first top inner edge 2628b.
The medial portion 2630 includes a plurality of divaricated-cut sections 2632 with medial elements 2634 adjacent to or therebetween. As with the first embodiment, the compressible electrical contact 2600 can include just a medial portion without the first and second contact ends.
Referring particularly to
In the substantially compressed state, shown in
A theoretical divaricated cut 3050B for a medial portion 3030B may be defined with respect to a first divaricating cut pattern PBT1, using predefined measurements DBC1, EBC1, and GBC1. DBC1 measures the overall height of the theoretical divaricated cut 3050B. EBC1 measures the maximum width of the divaricated cut 3050B and GBC1 is narrowest width of the of the divaricated cut 3050B. The first divaricating cut pattern PBT1 also includes an upper tapered section 3070B1, a lower tapered section 3072B1, and an arc section 3074B1 positioned between the upper tapered section 3070B1 and the lowered tapered section 3072B1. The arc section 3074B1 includes two arc segments BBT1, BBT2.
A theoretical divaricating cut 3060B for a tube end portion 3010B may be defined with respect to a second divaricating pattern PBT2, using predefined measurements DBC2, EBC2, FBC2, and GBC2. DBC2 measures the overall height of the theoretical divaricated cut 3060B. EBC2 measures the distance from the centerline of the cut 3060B to the edge of the tube 3026B. FBC2 is the widest width of the divaricating pattern PBT2 and GBC2 is narrowest width of the divaricating pattern PBT2.
Divaricating patterns PBT1, PBT2 are further defined with respect to dimensions HBc and DBM2. Measurement HBc is the distance between the patterns PBT1, PBT2 measured from their respective centerlines and DBm2 is the distance from the bottom of divaricating pattern PBT2 to the median of the arc section 3074B1, which is parallel with central axis CB.
Preferably, the divaricating patterns PA, PB may cut at internals in the tube are such that they allow the final form of the divaricated-cut contact to exhibit spring-like properties. Moreover, in the embodiments disclosed herein, zig-zag like patterns are preferable such that the final properties of the contact are spring-like. The divaricating patterns PA, PB are also configured such that the amount of bowing that could occur in the medial portion, after cutting of the tube and during compression is minimal. Alternative variations and divaricating patterns may, however, be used.
The compressible electrical contacts disclosed herein are preferably manufactured from tubes using one or more precision cutting methods, e.g. laser cutting. The tube is also preferably manufactured from one or more electrically conductive materials. Suitable materials for the compressible electrical contact include, but are not limited to, brass, copper, beryllium copper and stainless steel. Preferably, these materials have spring-like properties, high strength, high elastic limit, and low moduli.
Overall dimensions for the compressible electrical contacts disclosed herein can range from micro- to large scale. Targeted sizes, however, are on a smaller basis given current industry trends. An exemplary tube size has an inner diameter of about 0.006 inches, an outer diameter of about 0.010 inches, and an overall length of about 0.070 inches. When the compressible electrical contact is manufactured, using a tube having these dimensions and incorporating divaricating pattern, PA, the resulting cut angles can be about 5 degrees, the innermost cut distances can be about 0.001 inches and the outermost cut distance can be about 0.002 inches. And, when the compressible electrical contact is manufactured, incorporating divaricating pattern PB, the resulting outermost cut angles can range from about 13 degrees to about 15 degrees, the resulting innermost cut angles can range from about 1.5 degrees to about 3.0 degrees with the innermost cut distances being about 0.0006 inches and the outermost cut distance being about 0.002 inches.
Dimensions of the compressible electrical contacts disclosed herein, however, depend on various factors, including but not limited to the contact's spring rate and the length of travel between a substantially relaxed state and a compressed state. Nonetheless, after compression, the compressible electrical contacts disclosed herein will have an effective inner diameter of about 0.006 inches, an effective outer diameter of about 0.010 inches, and an overall length of about 0.070 inches, when manufactured from a tube having an inner diameter of about 0.006 inches, an outer diameter of about 0.010 inches, and an overall length of about 0.070 inches.
It will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit or scope of the disclosed embodiments. Since modifications combinations, sub-combinations and variations of the disclosed embodiments incorporating the spirit and substance of the embodiments may occur to persons skilled in the art, the disclosed embodiments should be construed to include everything within the scope of the appended claims and their equivalents.
