A plug connector, comprising a housing 12 comprising a flat plug portion 14 extending in the left-right direction for insertion into a plug accommodation space 54a of a housing 52 of a receptacle connector 50 serving as a joining mate, and a signal contact 22 provided at the upper surface of the plug portion 14 and connected to a signal line (signal terminal on a board), the configuration of the plug connector being such that the signal contact 22 is brought into contact with a signal contact 62 of the mating connector in a state where the housing 12 has been joined to mating housing 52, wherein a power source contact 24 for connection to a power source line (power source terminal on a board) is provided at the lower surface of the plug portion 14.
摘要:
A polygonal scanner of the present invention includes a rotary body including a ceramic rotary sleeve and a metallic cylindrical member shrinkage-fitted on the rotary sleeve. The cylindrical member is formed with mirror surfaces constituting a polygonal mirror. A dynamic pressure, air bearing supports the rotary body. The mirror surfaces overlap the rotary sleeve in the axial direction of the rotary sleeve. A hole greater in diameter than the dynamic pressure, air bearing is formed in the top wall of the cylindrical member. The cylindrical member includes a stress removing portion positioned between the mirror surfaces and the rotary sleeve for removing a stress ascribable to shrinkage-fitting.

An electronic-part inspection device 20 comprises a plurality of terminals 30, a left terminal-retaining member 51 and a left swinging member 71, and each terminal 30 comprises a terminal base portion 31, a swinging arm portion 33, a contact portion 35 and an engaging portion 37. The terminal base portion 31 is located in the lower part of the terminal 30 and retained in the left terminal-retaining member 51, and the swinging arm portion 33 extends upward from the terminal base portion 31 and is capable of undergoing elastic deformation to swing back and forth. The contact portion 35 is located at the upper end of the swinging arm portion 33, and the engaging portion 37 is also located at the upper end of the swinging arm portion 33. The left terminal-retaining member 51 comprises base-receiving portions 58, which retain the terminal base portions 31 of the terminals 30, and a counter surface 63a provided on a middle wall 63 that exists in the base-receiving portions 58. Furthermore, the left swinging member 71 comprises pivotally engaging portions 71d, which are positioned behind and against the contact portions 35 of the terminals 30 and are engaged to the engaging portions 37 of the terminals 30.
