Abstract: An electrical connector has a main unit with and integral row of parallel connector pins. A first end of each connector pin is at a front of main unit and a second end is at a rear of main unit. Each parallel connector pin is bent downward toward the back so that they project downward from the bottom surface of main unit. A socket shield made from a thin plate surrounds the upper and lower surfaces and the two side surfaces of main unit. A pair of substrate fixing claws project downward from the sides of the lower surface at the rear of main unit. The socket shield also has an engagement piece projecting downward from the front region of the lower surface. The pair of substrate fixing claws and the engagement piece both engage the mounting substrate when the electrical connector is mounted on the mounting substrate.

Abstract: A hinge device is provided for pivoting a cover to a base housing and is designed such that when the cover is in a closed position it does not easily come off the base housing when subjected to external force yet the cover is easily and readily removable for replacement. The hinge device has an engagement hole 12c disposed on a housing 12 to pivotably support a cover 13 around a pivot axis, an engagement portion 13a is disposed on cover 13 to rotatably fit in the engagement hole and is formed relatively short so that it can easily disengage from engagement hole 12c when an impact is received. An arcuate guide groove 12d is formed on the housing around the engagement hole so that a guide pin 13b on the cover can engage with the guide groove to guide cover movement between open and closed positions as well as aid in absorbing impact forces acting on the cover when the cover is closed.
