An electrical contact and lead frame having a contact base and a tab section. The tab section extends from the contact base. The tab section has a first wall and an oppositely facing second wall. The first wall and the second wall are configured to make an electrical and mechanical connection to a mating receptacle portion of a mating contact of a first mating plug assembly. An insulation displacement slot is provided in the tab section. The insulation displacement slot extends from the end surface. The insulation displacement slot is configured to make an electrical and mechanical connection to electrical conductors of a second mating assembly.

An electrical connector includes a plug that mates with a receptacle. In a medical application, the plug is connected to electrical leads that pass through a patient's skin to an implanted medical device in the patient's body, while the receptacle is connected to external medical equipment. All electrical contacts in the plug are on internal portions. The receptacle includes annular contacts that contact the internal electrical contacts on the plug when the plug and receptacle are properly mated. The receptacle includes a plurality of annular electrical contacts that have a first diameter and are separated by a plurality of annular insulators having a second diameter smaller than the first diameter.

A connector portion includes a first system connector that holds a first system terminal and a second system connector that holds a second system terminal. An insertion/removal direction of the first system connector and the second system connector are the same as an axial direction of a motor. The first system connector and the second system connector are arranged close to each other such that the long length directions of the frontages of the connectors are aligned, and that the interval between the connectors is smaller than the width in the short length direction of both connectors. The connectors have protrusions that project in a direction orthogonal to the direction in which the connectors are arranged.

An electrical connector includes a plug that mates with a receptacle. In a medical application, the plug is connected to electrical leads that pass through a patient's skin to an implanted medical device in the patient's body, while the receptacle is connected to external medical equipment. The plug is small in diameter so the size of the opening in the patient's skin can be minimized. All electrical contacts in the plug are on internal portions. The receptacle includes annular contacts that contact the internal electrical contacts on the plug when the plug and receptacle are properly mated. When the plug is plugged into the receptacle, spring-loaded retention arms in the receptacle lock into place on the plug, retaining the plug in the receptacle.

A retrofit receptacle assembly includes one or more receptacle housing members, each having an inner portion which extends outwardly beyond the housing member defining an asymmetrical opening therebetween to secure a male connector. The inner portion includes openings to secure electrical prong members from the male connector. Electrical connectors extend from the inner portion to electrical power lines from a dockside power pedestal. A mounting assembly portion of the retrofit receptacle assembly secures the receptacle to the dockside power pedestal.

The present disclosure provides a new gate lamp system and method. The system and method is configured to facilitate the installation of a gate lamp onto a gate arm, and to facilitate the replacement of one or more of the gate lamps. The present disclosure provides a system and method of installing gate lamps on a gate arm in the field in a robust manner with ease.

A serially-connectable light string includes a first power wire, a second power wire, a first electrical connector, a second electrical connector and a plurality of light emitting diodes. The first power wire and the second power wire are arranged in parallel. The first electrical connector is connected to one end of first power wire and one end of the second power wire. The second electrical connector is connected to the other end of first power wire and the other end of the second power wire. The first electrical connector and the second electrical connector respectively include a plurality terminal portions corresponding to the first power wire and the second power wire.

A serially-connectable device includes a plug, an electrical cable, and a joining sleeve. The plug includes an insert portion and apertures are arranged in parallel to each other and formed through the insert portion. The electrical cable includes metal wires, such as wires of a light string. Ends of the wires respectively run through the apertures, and are folded back onto a surface of the insert portion to form exposed wire portions servicing as terminal pins. The joining sleeve includes two insert holes. Electrical conductors are disposed within the joining sleeve. Each electrical conductor extends from one of the two insert holes to the other insert hole. The insert portion is inserted into one of the two insert holes, to have the pins respectively contact the electrical conductors. Through the combination of the joining sleeve and the plug, two electrical cables can be quickly connected in a serial manner.

An apparatus for locking electrical connectors together and for protecting such electrical connectors. A method of locking electrical connectors together.
