  • Patent number: 7887372
    Abstract: A fastening device for a low-profile fuses of vehicle, which can achieve simple and robust coupling of the low-profile fuse while enabling the fuse to be easily connected to or disconnected from a vehicular junction box, is disclosed. The fastening device serves to connect or disconnect the low-profile fuse to or from the junction box via upward/downward movement thereof while maintaining coupling between the low-profile fuse and the junction box, and includes a socket integrally formed at an upper surface of the junction box and having plug coupling recesses and a fuse connecting recess indented in the upper surface of the junction box, terminals being disposed inside the fuse connecting recess so as to be exposed to the outside, and a plug vertically movably coupled in the socket while being coupled laterally with the low-profile fuse to enable connection or disconnection between the low-profile fuse and the terminals.

  • Patent number: 7632116
    Abstract: A connector having a first connector portion with a first connection interface and a guide projection is disclosed. The connector also has a second connector portion with a second connection interface configured for insertion into the first connection interface. The connector also has a lever having a guide channel configured to receive the guide projection. The lever is linearly movably connected to the second connector portion and is positionally biased away from the second connector portion. While the guide projection is within the guide channel, movement of the lever from a fully positionally biased location with respect to the second connector portion initiates a change in a state of connection between the first connector portion and the second connector portion.

  • Publication number: 20060166526
    Abstract: Disclosed herein is a double printed circuit board with a solderless connecting structure, which electrically connects an upper board and a lower board of the double printed circuit board without soldering. The double printed circuit board comprises upper and lower boards, each having a hole with a conductive layer formed on an inner surface thereof. A pin is press-fitted through the holes of the upper and lower boards, and has upper and lower compliant portions formed at upper and lower portions of a pin body to electrically connect the upper board and the lower board, respectively. Since the pin comprises the upper and lower compliant portions, the pin can maintain stable connection between circuits of the upper and lower boards while being firmly coupled to the printed circuit boards, and minimize environmental contamination due to lead.
