Definitions

  • This invention relates to an electrical connector. More particularly, it relates to a connector for attaching an electrical cord to an electrical appliance, which connector includes an ejector by which it and the cord may be detached from the appliance.
  • the connector of the present invention solves these problems because it can be operated with one hand by application of finger pressure on the ejector of the connector.
  • Ejectors for use with electrical connectors are known.
  • U.S. Pats. Nos. 1,900,782; 2,051,425; 2,134,345; 2,142,184, 2,703,869; and 3,440,405 disclose electrical connectors having ejectors which operate on a cam principle.
  • U.S. Pats. Nos. 1,531,604; 2,259,799; 2,445,608; and 3,737,623 disclose bar or plunger operated ejectors.
  • U.S. Pat. No. 2,955,273 discloses a spring operated ejector for an electrical connector.
  • Other state of the art patents known to the applicants herein are U.S. Pats. Nos. 2,926,230; 3,417,214; 3,573,695; and 3,587,021.
  • Two ejectors of this invention are cam operated.
  • a third ejector herein is operated on the "hinge" principle described in detail below.
  • Such ejectors do not have the same construction nor operate in the same manner as do the prior art ejectors mentioned above.
  • an ejector for disengaging the connector and an electrical cord attached thereto from an electrical appliance.
  • the ejector includes first and second components.
  • the first component is movable through and out of the connector to bear against the appliance when the connector engages the appliance and the second component is movable by the application of pressure thereon to cause movement of the first component against the appliance, whereof the connector is moved in an opposite direction and disengaged from the appliance.
  • the first component is a flat bar and the second component is integral with the first component and has a hince shape. By finger pressure on the second component to flatten it, the first component is moved against the appliance and the connector is disengaged from the appliance.
  • FIG. 1 An electrical connector of this invention is shown in Fig. 1, wherein it is indicated at 10. As described below, one end of the connector is removably attachable to an appliance, such as the hair drying cap generally indicated at 11 in Fig. 1, and the other end of the connector is fixedly attached to an electrical cord 12.
  • the cord has at its other end a conventional plug 13 for connecting the appliance to a power source.
  • the structures of cap 11 relevant to this invention include a plate 14 affixed to the outside of the cap, a heating element (not shown) within the cap, and electrical terminals 15 extending out of the cap through plate 14 and in electrical contact with the heating element.
  • the structures of cord 12 relevant to this invention include wires 16 extending into connector 10. At the free end of each of the wires is a contact 17.
  • the structure of the contacts is not critical to this invention. Generally the contacts will have a structure corresponding to that of terminals 15, so that current may be delivered from the power source through plug 13, cord 12, contacts 17, and terminals 15 into the heating element of cap 11.
  • the structure of connector 10 is best shown in Fig. 3.
  • the connector includes a base 18 and several openings.
  • a first opening 19 is provided for receiving wires 16 of cord 12, as described above.
  • a pair of openings (not shown) are provided in which contacts 17, which are attached to wires 16, are received.
  • the irregular shaped opening 20, shown best in Fig. 3, is provided in which an ejector 21 is received.
  • Opening 2G extends horizontally through base 18 from the end of connector 10 adjacent plate 14 into generally the center of the connector, where it widens and extends vertically upward to the top surface of the connector. The reason for the irregular shape of opening 20 will be apparent from the discussion below concerning ejector 21.
  • ejector 21 is made of, preferably, a flexible plastic and has essentially two portions.
  • the first portion is flat and extends between the outermost end of the connector adjacent plate 14 and the upwardly extending section of opening 20.
  • the second portion of ejector 21 has the shape of a "hinge” or is triangular in shape and extends out of the upwardly extending section of opening 20 of connector 10 when the connector is attached to cap 11.
  • ejector 21 can be operated to detach connector 10 from cap 11 without the operator having to touch the cap.
  • ejectors which operate on a cam principle, are shown.
  • the ejectors of Figs. 5 and 6 are made of two separate components.
  • these ejectors utilize a flat bar component, generally indicated at 23, which is similar to the first portion of ejector 21 described above, for contacting plate 14 to disengage the connector from cap 11.
  • a second cam component generally indicated at 24, is moved in the direction of the arrows shown to act on component 23.
  • terminals 15 of the cap are engaged with contacts 17 causing the respective ejectors shown to resume their initial positions because the flat bar components thereof are pushed away from terminals 15 and return springs or similar means (not shown) operate to return the cam components to the positions shown in Figs. 5 and 6.
