Definitions

  • Modular Assembly RELATED APPLICATIONS [0001] This application claims priority to United States Provisional Application No. 61/991,699, filed May 12, 2014, which is incorporated herein by reference in its entirety.. TECHNICAL FIELD [0002] This disclosure relates to the field of modular assemblies, more specifically to modular assemblies with at least two halves that are battery powered. DESCRIPTION OF RELATED ART [0003] Modular assemblies are known. Examples include power tools (such as but not limited to battery powered drills) and numerous other types of equipment that are capable of receiving or using high current.
  • the battery In the case of power tools, typically the battery is removable and can be charged separately but in operation a substantial amount of current (more than 2 amps and often more than 5 amps) can be used when the power tool is in operation.
  • Other types of equipment can include an integrated battery that is not intended to be removed for recharging (instead a connector is provided that is coupled to the battery). In such a configuration it is desirable to provide current at a relatively high rate so that the battery can be quickly charged.
  • both types of components benefit for being able to accept high current.
  • Existing such modular assemblies, while effective, tend to be constructed in a manner that is extremely manual in nature.
  • Wires are soldered to terminals and to motors or power storage units (such as batteries or capacitors) and because of the high current, tend to be relatively larger diameters (sometimes 14 gauge or larger).
  • the existing assemblies are difficult to assemble and because of the design, do not lend, cannot be made in an automated fashion. [0004]
  • the low cost of labor in many countries meant that the manual requirements were not problematic.
  • the cost of labor has risen dramatically. Therefore it has become more challenging to manufacture designs with large amounts of labor.
  • the use of manual labor for repetitive tasks, while sometimes required, is less desirable as operators can easily make mistakes due to boredom if they are doing the same operation over and over.
  • a modular assemblies includes a first housing and a second housing that are configured to join together to form a housing with an internal volume.
  • Each housing can support one or more terminals.
  • the terminals can include a first contact on one end and a second contact on anther end and a body extending therebetween.
  • the body can be integrated into the housing so that it is substantially contained therein and the contacts are exposed sand configured to engage other terminals.

As can be appreciated, however, any number of other shapes and configurations are possible. Thus, without limitation, the modular assembly could be a battery powered tool such as circular saw or a reciprocating saw.
  • the modular assembly 10 could be a vacuum cleaner, hair dryer or any other device that is battery powered. In devices, such as vacuum cleaners where the battery is more desirably integrated into the assembly and is hidden without the housing, terminals can be provided to deliver high levels of current to the battery.
  • the modular assembly 10 includes a housing assembly 20 that includes a first housing 21 a and a second housing 21b that are configured to be coupled together.
  • the housing assembly 20 supports a control switch 50 (which in the depicted embodiment is shaped in the form of a trigger) that is configured to control operation of the modular assembly 20. Additional switches can be added as desired if additional functionality and/or controls is/are desired.
  • the housing assembly 20 supports terminals 26, 27, 28 that are configured to engage contacts on a separable battery pack (not shown) as is common in battery operated power tools.
  • Each of the terminals 26, 27, 28 includes a contact 29 to engage the battery pack and the contacts can have an appropriate plating to ensure good electrical connection between the module assembly 10 and the separable battery pack.
  • One or more of the terminals 26, 27, 28 can have a contact 30 that is configured to engage a pad on a circuit board assembly 40 and is positioned in a power source pocket 25.
  • the terminals (including their corresponding body) are visible in the depicted illustrations. This is for purposes of ease of depiction.
  • the housing assembly 20 provides an internal volume 22 that can be used to support and contain various components.
  • the depicted embodiments depict the internal volume 25 supporting a circuit board assembly 40, a control switch 50 and a motor assembly 70.
  • the motor assembly 70 is an embodiment of an energy consumption device and energy consumption devices often are configured to convert electrical energy into some other form of energy, such as mechanical or thermal or a combination thereof.
  • the energy consumption device can also convert electrical energy into other forms, such as but without limitation, light or sound.
  • the housing can be formed so that it extends along an X-axis and a Y-axis and has walls that define the internal volume and form a recess/cavity that is directed in the Z axis.
  • each of the depicted components that are positioned in the internal volume can include contacts that configured to engage contacts of the terminals (either provided on or molded within the housing) in a manner that allows insertion of the components in the Z-axis.
  • the first housing 21a (for example) can be formed and can support one or more terminals with contacts that are exposed and intended to engage other contacts.
  • the first housing 21a can be laid on its side (with the opening facing away from the supporting surface) and components (such as circuit board assembly 40, the control switch 50 and the motor assembly 70) can be automatically installed through the use of known assembly equipment, such as but without limitation, pick and place equipment.
  • the second housing can be formed with one or more terminals (or terminal equivalents, as will be discussed below) insert molded into the housing.
  • the the second housing 21b can be installed to the first housing 21a along the Z-axis so as to form the housing assembly 20 and the first and second housings 21a, 21b can be secured together with known fastening techniques such as screws, adhesives, heat staking and the like.
  • the two housings 21a, 21b are secured with a fastener mechanism that can be undone.
  • a convention screw is a beneficial configuration.
  • the second shot could be a different material that provides a change in appearance, material properties or provides an additional layer to the housing (which can enable more complex insert-molded structures).
  • the terminals (such as terminals 26, 27, 28, 31, 35 and 38) are intended to carry significant amounts of current (preferably more than 2 amps and more preferably more than 5 amps) thus they need to be sized so as to appropriate care the current load without overheating.
  • Fig. 7 illustrates features of the terminals that each include contacts (such as contacts 32, 34, 39) that are configured to engage contacts on components that are intended to be installed within the enclosure 22.
  • one or more circuit elements 18 can be attached to the terminals. The circuit elements 18 could be electrically attached to the terminals with solder or be attached with an interference fit.
