  • Patent number: 6296492
    Abstract: A compact receptacle for mating connection with a complementary coaxial plug connector. The receptacle is in use to be mounted on a mobile phone for switching a signal line from an internal antenna to a vehicle's external antenna when placed on a cradle in a vehicle in mating connection with the plug connector on the cradle. The receptacle has a dielectric mold carrying an outer conductor shield fitted on top of the mold, a single spring member, and a single fixed contact member. The conductor shield includes an electrode socket for connection with an outer conductor tube of the plug. The spring member integrally carries a center electrode for connection with a center conductor post of the plug, and a movable contact which forms a normally-closed switch with a fixed contact on the fixed contact member for the above signal switching.

  • Patent number: 5975916
    Abstract: A lowered profile electrical connector assembly is composed of a socket and a detachable plug. A flat dielectric socket base mounts a plurality of arrayed first terminals each having a first spring contact. A dielectric plug base mounts a plurality of arrayed second terminals each having a second spring contact. Each first terminal includes a first lead which extends outwardly from a bottom of the socket base for electrical connection with an external circuit. The first and second terminals are each provided with first and second leads for electrical connection with external circuits. Each first terminal is shaped to have a S-shaped section composed of inverted and upright U-shaped portions which are continuous with one leg of the upright U-shaped portion shared by the inverted U-shaped portion. The upright U-shaped portion includes a free spring leg which defines the first spring contact having a free contact end for engagement with the second spring contact.

  • Patent number: 5584713
    Abstract: A connector comprises a socket adapted to be mounted in a potable radiotelephone having an internal power supply and a plug having a power code for supplying electric power from an external power supply to the radiotelephone. The socket has a pair of input terminals, movable and stationary terminals. The movable terminal is formed with a pair of torsion members each of which has a contact. The contacts are urged to the stationary terminal to make a first electrical connection therebetween for allowing a first operation of the radiotelephone with the use of the internal power supply. For preventing an accidental breakage of the first electrical connection which is caused by dust or pieces of thread put between the movable and stationary terminals, a contact-point between one of the contacts and the stationary terminal is displaced from that between the other contact and the stationary terminal in an inserting direction of the plug into the socket.
