  • Patent number: 9912081
    Abstract: A cover assembly for an electrical connector at the end of a sheathed cable containing several insulated wires. An insulation piercing clip couples light bulb leads to the wires. A translucent housing encloses the light bulb, said insulation piercing clip, the entire section of unsheathed insulated wires, a portion of the electrical connector and a portion of the sheathed cable. The cover assembly is illuminated by the light bulb when power flows through the electrical connector and may be color coded to indicate connector function.

  • Patent number: 9781772
    Abstract: A heat mat with thermostatic control having a reference voltage generating source that provide high voltage DC for a power controller and low voltage for a temperature sensor and hysteresis circuit. The sensor and hysteresis circuit establish a temperature threshold signal that is delivered to the resistance heating element. The resistance heating element is sandwiched between two layers of material with adhesive. Two layers of PVC protects the sandwich. In manufacturing the heat mat, the resistance heating element is placed with adhesive between two layers of material then cured and degassed under vacuum. The thermostatic control is sealed within an overmold housing or flat pack.

  • Patent number: 9614361
    Abstract: A waterproof seal for electrical assemblies having conductive wires attached to a metal contact and inserted into a connector body. The conductive wires and metal contact are coated with solder to fill the gaps. The space between the soldered wires and the connector body are filled with an epoxy. The wire insulation and connector body are continuously sealed with a bonding agent. A section of wire insulation and the connector body are encased within an outer plastic jacket overmold.
