  • Patent number: 11728603
    Abstract: A novel electrical box to house one or more ISO micro relays, is adapted to support IP67 and IP69K Ingress Protection ratings. The housing of the electrical box is molded with blade sockets that correspond to blade positions of the ISO micro relay. The housing is also molded with terminal seats and cylindrical openings which vary, depending on the blade socket, enabling terminals of different sizes, orientations, and positions relative to the respective blades, to be easily inserted into the back of the housing. The resulting position of the terminals ensures that electrical connections to the ISO micro relay are made and ingress protection of components inside the electrical box is ensured.

  • Patent number: 11611172
    Abstract: A novel busbar, suitable for low-power applications, features a u-shaped extension having a male terminal that fits into and establishes electrical connection with a standard female terminal. The housing of an electrical box including the busbar is modified to receive the female terminal in such a way that Ingress Protection ratings of IP67 and IP69K are maintained within the electrical box. The busbar is not riveted to a thicker busbar terminating with a stud and lug nut, as in legacy configurations, thus being simpler and cheaper to manufacture. The female terminal, once connected to the busbar, is removable by inserting a tool into a dedicated opening within the housing.

  • Patent number: 6048219
    Abstract: An electrical connector for configuring the supply voltage of rotary electric machines, particularly electric motors, having a plurality of electrical windings. The connector includes an electrical terminal block mountable in a bell housing of the rotary electric machine. The terminal block includes a socket having a plurality of female electrical connectors coupled to a corresponding plurality electrical windings. A male electrical connector having a plurality of jumper pins matably engageable with the female electrical connectors of the socket in a first and second configurations to electrically configure first and second winding portions of each electrical winding in parallel or in series. The connector also includes a visual electrical configuration indicator to indicate whether the male electrical connector and socket are in the first or second configurations.

  • Patent number: 5875522
    Abstract: A grommet and adjustable strap fastener assembly including an elongate strap member having a head portion at a first end in combination with at least one body member having a first strap aperture for receiving the elongate strap member. A retention member protruding into the first strap aperture of the body member permits adjustable passage of the elongate strap member through the first strap aperture in a first direction. The retention member prevents passage of the elongate strap member through the first strap aperture in a second direction opposite the first direction. According to another aspect of the invention, the body member includes a second strap aperture disposed in a recess wherein the head portion of the elongate strap member is disposable in the recess of the body member when the elongate strap member is disposed through the second strap aperture.
