  • Patent number: 11399883
    Abstract: An electrocautery device and system include retractability and extension of a cauterizing tip without impacting or applying backpressure to the supporting electrical components inside the device. In some embodiments, a conductive rail is in constant contact with a spring contact electrically coupled to the power source as the cauterizing tip is retracted or extended from the main housing. Some embodiments include a vacuum system that draws fluid from the treatment site during operation. The fluid travels through a passageway that is sealed off from the electrical components by virtue of aspects of the device. Some embodiments include an ergonomic design and are lower cost by using membrane switch circuits instead of a printed circuit board.

  • Patent number: 9954337
    Abstract: Overmolded electrical plugs with integrated strain relief are disclosed. The strain relief may have multiple protrusions extending though the overmolded housing which are visible to users. The strain relief may employ a ratcheting mechanism which permanently secures the strain relief on the electrical power cord. The strain relief may be partially assembled in a pre-lock configuration on the electrical power cord where the strain relief may be positioned on the power cord, and then be further pressed to a locked configuration in which the is securely attached to the power cord. The strain relief is self-aligned on the electrical plug during an assembly process.

  • Patent number: 9744703
    Abstract: Electrical plugs having single and double insulation as well as the method for manufacturing the double insulating electrical plugs are disclosed. The single insulated electrical plugs have internal walls which electrically isolate the electrical connectors. The single insulated electrical plug has a one-piece body with a central base which accepts the electrical connectors, as well as two covers hingably coupled to the base to secure the connectors in place. The double insulated electrical plugs are insulated by both an inner body as well as the overmold material. The inner body has vents which enable overmold material to be injected into the inner portions of the inner body as well as onto the outside of the inner body. During the manufacturing process, molten material flows over the outside of the inner body, and also flows into the interior of the inner body to provide two layers of electrical insulation.

  • Publication number: 20140248789
    Abstract: Lockable electrical connector assemblies that couple electrical connectors to prevent the electrical connectors from unintentionally disconnecting are disclosed. The electrical connector assembly has a first electrical connector, a second electrical connector, and a retention ring that has one end surrounding and able to rotate about the second electrical connector. The first electrical connector preferably has tabs that extend away from the first electrical connector. The retention ring has a second end shaped to receive and lock the tabs of the male electrical connector. To form a locked connection, a user rotates the retention ring that causes the retention ring to confine the tabs of the first electrical connector. The user continues to rotate the retention ring until retention ring is placed into a locked position.
