A connector includes a first connector housing having a resiliently deflectable lock arm in an outer wall of the first connector housing and a second connector housing having a lock arm engaging with a locking piece fitted in the first connector housing. In the complete engaged state of the pair of connector housings, the lock arm engages with the locking piece so that the first and second connector housings are secured to each other. The connector further includes an engagement confirming member movably attached to the lock arm and an engagement retaining wall standing and positioned adjacently to the engagement confirming member. In the complete engagement of the pair of connector housings, the engagement confirming member is moved onto a top portion of the engagement retaining wall to prevent the lock arm from deflecting. The engagement confirming member is preferably attached movably in a substantially orthogonal direction to the engagement direction of the connector housings.

A connector fastening nut for a bolt-nut fastened connector comprises: a nut member (A, B, C, D) fixed to a first connector housing (M) and formed with a female threaded portion (1) engaged with a male threaded portion (5) of a fastening bolt (4) fitted to a second connector housing (F); and an elastic portion (3c, 7c, 8c, 10a) formed integral with the nut member, for urging an end of the fastening bolt in an engagement direction between the female threaded portion of the nut member and the male threaded portion of the fastening bolt, when the male threaded portion has been passed through the female threaded portion after full engagement of the two connector housings (M, F) by fastening the fastening bolt to the fastening nut. The connector fastening nut can engage/disengage the two connector housings smoothly, while preventing the damage of the threaded portions thereof and improving the water-tightness of the fastening nut.

A waterproof connector includes :a connector housing (11) formed with a plurality of oval terminal insertion holes (12) arranged at close intervals in a minor axis direction of the oval terminal insertion holes; and a waterproof plug (30) for sealing a gap between the wire (4) inserted into the terminal insertion hole (12) and an inner wall of the terminal insertion hole, having an inner cylindrical portion (32) and an outer cylindrical portion (33). The inner cylindrical portion (32) air-tightly is fitted to an outer circumference of the wire (4). The outer cylindrical portion (33) brought into tight contact with the inner wall of the terminal insertion hole (12) when the waterproof plug is pressure inserted into the terminal insertion hole. The outer cylindrical portion (33) is formed Integral with the inner cylindrical portion (32) so as to provide a hollow cylindrical portion (35) between the inner and outer cylindrical portions. The hollow cylindrical portion (35) absorbs deformation of the outer cylindrical portion pressure inserted into the terminal insertion hole.

A connector housing has a body portion and a hood portion. An insertion detecting member for terminal lugs is movable from provisional locking position to full locking position inside the hood portion. A resilient, terminal-lug locking piece extends in each terminal accommodating cavity in the housing body portion to form a displacement permitting space on a side opposite a side where a terminal lug is inserted. The insertion detecting member has a main frame, insertion detectors corresponding to the displacement permitting spaces, and a pair of manipulating portions at opposite sides of the main frame. When in provisional locking position the manipulating portions are exposed at opposite sides of the housing body portion, and when in full locking position the insertion detectors move into the displacement permitting spaces. The insertion detecting member is easily movable from provisional locking position to full locking position inside the housing hood portion.

There are provided a resilient engaging piece to the terminal metal part provided through the resilient displacement permissible space opposite to the terminal accommodating cavity formed at a connector body portion of the connector, and the insertion detecting body corresponding to the resilient displacement permissible space at the main frame portion of the insertion detecting member for terminal metal parts and a pair of manipulating pieces each at opposite sides thereof. The insertion detecting member for terminal metal parts is caused to move freely to enable the main frame portion thereof to come into contact with the inside wall surface of the hood portion. The pair of manipulating pieces are exposed at both sides of the housing body portion through the window of the hood portion at the provisional engaging position, and the insertion detecting body can be moved to enter into the resilient displacement permissible space at the formal engaging position.

A receiving apparatus for receiving an orthogonal frequency division multiplexing (OFDM) signal including a frame having one frame length of a plurality of patterns. The apparatus comprises an acquiring section to acquire information regarding a preamble signal from an OFDM signal from a transmitting apparatus; a frame determining section to determine whether the one frame length is short in the frame based on the information regarding the acquired preamble signal; and a time interpolating section to obtain transmission path characteristics by comparing a pilot contained in the preamble signal with a known pilot corresponding to the pilot in a phase of transmission, when the frame determining section determines that the one frame length is short in the frame, and to interpolate a data portion in a time direction based on transmission path characteristics.
