An airtight connection assembly comprising conducting members constituting passages of a signal or fluid, a sealing part including a first sealing member with a shape which can cover a first hole formed in a partition of an airtight container and a sealing material, and a connecting part comprising a connector connected to either or both of ends of the conducting members, second holes formed in said first sealing member so as to communicate the inside and outside of the airtight container with each other, the conducting members are individually inserted through the second holes, and gaps between the conducting members and inner circumferential surfaces of the second holes are filled with a sealing material. Thereby, it is made possible to deliver and receive an electric signal etc. between the inside and outside of the airtight container while maintaining airtightness of the airtight container by a simple configuration.

The present disclosure relates to a process connection for connecting a sensor to a process inlet via a process seal and a fixing element. The process connection includes a sensor housing and a clamping element. The sensor housing has a housing body configured to receive the sensor and a housing collar that extends around the housing body and has a first sealing section, which encircles the housing body, and a contact area. The housing collar is formed integrally with the housing body. The first sealing section is suitable for receiving the process seal to connect the process inlet to the housing collar in a fluid-tight manner. The clamping element has a contact area which is suitable for coming into contact with the contact area of the housing collar to press the housing collar onto the process seal.

A diagnostic disc includes a disc-shaped body having raised walls that encircle the interior of the disc-shaped body and at least one protrusion extending outwardly from the disc-shaped body. The raised walls of the disc-shaped body define a cavity of the disc-shaped body. A non-contact sensor is attached to each of the at least one protrusion. A printed circuit board (PCB) is positioned within the cavity formed on the disc-shaped body. A vacuum and high temperature tolerant power source is disposed on the PCB along with a wireless charger and circuitry that is coupled to each non-contact sensor and includes at least a wireless communication circuit and a memory. A cover is positioned over the cavity of the disc-shaped body and shields at least a portion of the PCB, circuitry, power source, and wireless charger within the cavity from an external environment.

Methods for installing electronic connections into a Factory Mutual certified cabinet may comprise providing a double walled cabinet. The double walled cabinet ay comprise an outer cabinet wall, and inner cabinet wall, and an airgap between the inner cabinet wall and the outer cabinet wall. The method may comprise the steps of including a first large hole in a surface of the outer cabinet wall and including a first small hole in a surface of the inner cabinet wall. Methods can additionally include the steps of inserting a first bulkhead fitting into the first small hole in the surface of the inner cabinet wall via the first large hole and covering the first large hole in the surface of the outer cabinet wall. Methods may additionally include the first small hole at least partially overlapping the first large hole when viewed from a plane normal to the first large hole.

The connection device for connecting two electric units, including a case in which are arranged: an electric wire to be linked to the first unit and including a conductive core encircled by an insulating sheath and a conductive tab to be linked to the second unit and secured with the stripped end of the conductive core, all of which being immersed in a sealing material filling the case and bonded to the insulating sheath, the device including an intermediate envelope partially coating the insulating sheath, so that it is in contact with the sealing material only over a reduced portion, where the intermediate envelope is in sliding contact with the sealing material and/or the insulating sheath.

[Problem] Provided is an airtight terminal that is configured to lessen distortion-borne stress caused in a metallic outer ring as a result of screw fastening or other fixing means to prevent the stress from readily propagating to an insulating material in a sealed place of a lead.

[Solution] An airtight terminal is provided that includes a metallic outer ring 13 having through holes 11 formed for screw fastening and sealing holes 12, leads 14 inserted through the sealing holes 12 in the metallic outer ring 13, and pieces of an insulating, material 15 to seal gaps between the metallic outer ring 13 and the respective leads 14. The metallic outer ring 13 is provided with pairs of cavities 13a and steps 13b surrounding the respective sealing holes 12.

An improved ECU for a motor vehicle comprises a housing that includes a top portion and a bottom portion each with an associated gasket. A printed circuit board (PCB) is enclosed between the housing portions. The gaskets provide seals between the housing, portions and respective sides of the PCB and apply balanced forces to each side to minimize strain on the PCB. One or both gaskets may be electromagnetic compliance gaskets.

A waterproofing structure is disposed between a first assembling component and a second assembling component of an electronic device. The second assembling component is detachably installed on the first assembling component. The waterproofing structure includes a sealing component, an abutting component and a sliding component. The sealing component is located between the first assembling component and the second assembling component. The abutting component is fixed on the second assembling component. The sliding component is slidably installed on the first assembling component. When the sliding component slides along a first direction, the sliding component forces the abutting component to drive the second assembling component to move toward the first assembling component, so that the sealing component is pressed by the first assembling component and the second assembling component.

A terminal block electrically relays inside and outside of a partition wall sealing a liquid. The terminal block includes a housing disposed so as to penetrate the partition wall, a bus bar inserted into the housing, a seal member attached to the housing so as to seal a gap between the bus bar and the housing, and a holder assembled to the housing outside the partition wall with respect to the seal member so as to prevent the seal member from coming off. The bus bar extends across the inside and outside of the partition wall through a first through hole of the housing, a seal hole of the seal member, and a second through hole of the holder. Durability of a material constituting the housing to the liquid is better than durability of a material constituting the holder to the liquid.
