Abstract

Modular packaging includes a solid state relay and a function module, wherein the function module comprises a housing containing a printed circuit board and an elevating screw. The elevating screw comprises a first end with an external threading and a second end with an external threading, where the elevating screw may be selectively altered between a first position and a second position within the housing. Related embodiments are disclosed.

First claim

What is claimed is:

1. A modular apparatus, comprising:
a solid state relay comprising an exterior housing, the housing comprising a first portion generally defining a recess and further defining a bore with an internal threading, and a second portion detachably coupled to the first portion and defining an aperture with an internal threading, wherein the exterior housing encloses a first printed circuit board having at least a first input terminal and at least a first output terminal;
at least one function module removably coupled to the solid state relay;
at least a first elevating screw, the elevating screw having a first end and a second end, the first end comprising a first diameter and a first external threading that is compatible with the internal threading of the bore, and the second end comprising a second diameter and a second external threading that is compatible with the internal threading of the aperture; and,
wherein the elevating screw is configured to be selectively altered between a first position where the first external threading of the elevating screw is engaged with the internal threading of the bore, and a second position where the second external threading of the elevating screw is engaged with the internal threading of the aperture.

2. The modular apparatus of claim 1 , wherein the first position of the elevating screw provides sufficient spacing between the first end of the elevating screw and the housing for the installation of cabling without disconnecting the second portion of the housing from the first portion of the housing.

3. The modular apparatus of claim 2 , wherein the first position of the elevating screw provides sufficient spacing between the first end of the elevating screw and the housing such that a terminal may be installed or replaced.

4. The modular apparatus of claim 3 , wherein the first external threading of the elevator screw is designed to 8-32 UNC standards and the second external threading of the elevator screw is designed to ¼-40 UNS standards.

5. The modular apparatus of claim 4 , wherein the internal threading of the aperture and the internal threading of the bore are capable of being deformed up to 1/100th of an inch per inch.

6. The modular apparatus of claim 1 , wherein the solid state relay and function module are removably coupled by a mechanical retaining mechanism.

7. The modular apparatus of claim 1 , wherein the internal threading of the bore spans only a portion of the bore's length.

8. The modular apparatus of claim 1 , wherein the internal threading of the aperture spans only a portion of the aperture's length.

9. The modular apparatus of claim 1 , wherein the modular apparatus comprises a plastic material, resin, a plastic composite, or combinations thereof.

10. The modular apparatus of claim 1 , wherein the modular apparatus conforms to an International Protection standard of IP20.

11. The modular apparatus of claim 1 , further comprising:
a second printed circuit board enclosed in the solid state relay housing; and,
a spring operated sensing device configured to selectively establish electrical conductivity between the first printed circuit board and the second printed circuit board.

12. The modular apparatus of claim 1 , further comprising:
a visual indicator and a voltage recognition device, where the voltage recognition device is configured to receive an input range of voltages, recognize the actual voltage between the terminals of the solid state relay, and send to the visual indicator a signal with a first value if the actual voltage is within the input range or send to the visual indicator a signal with a second value if the actual voltage is not within the input range.

13. The modular apparatus of claim 12 , wherein the visual indicator is configured to emit a first display if it receives a signal with the first value and to emit a second display if it receives a signal with the second value.

14. The modular apparatus of claim 13 , wherein the visual indicator is a light-emitting diode, wherein first display is a green lighting and the second display is a red lighting.

15. A modular apparatus, comprising:
a solid state relay comprising an exterior housing, the housing comprising a first portion generally defining a recess and further defining a bore with an internal threading, and a second portion detachably coupled to the first portion and defining an aperture with an internal threading, wherein the solid state relay housing encloses a first printed circuit board having at least a first input terminal and at least a first output terminal;
at least one function module removably coupled to the solid state relay;
at least one elevating screw, wherein the elevating screw is configured to be selectively altered between a first position where the first end of the elevating screw is engaged with the first portion of the housing, and a second position where the second end of the elevating screw is engaged with the second portion of the housing; and,
wherein the first position of the elevating screw provides sufficient spacing between the second end of the elevating screw and the housing for the installation of cabling.

16. The modular apparatus of claim 15 , wherein the installation of cabling includes the installation of removal of a terminal.

17. The modular apparatus of claim 15 , further comprising:
a bore having an internal threading compatible to receive the first threading of the first end of the elevating screw, and an aperture having an internal threading compatible to receive the second threading of the second end of the elevating screw.

18. The modular apparatus of claim 15 , further comprising:
a second printed circuit board enclosed in the function modular housing; and,
a spring operated sensing device configured to selectively establish electrical conductivity between the first printed circuit board and the second printed circuit board.

19. The modular apparatus of claim 15 , further comprising:
a visual indicator and a voltage recognition device, where the voltage recognition device is configured to receive an input range of voltages, recognize the actual voltage between the terminals of the solid state relay, and send the visual indicator a first signal if the actual voltage is within the input range or send the visual indicator a second signal if the actual voltage is not within the input range.

20. The modular apparatus of claim 19 , wherein the visual indicator is configured to emit a first display if it receives a signal with the first value and to emit a second display if it receives a signal with the second value.
