    • A rear holder 4 is inserted into a housing 3 from a rear end surface 24 at a provisional locking position in which the rear holder 4 is inserted into the housing 3 halfway and an insertion of connecting terminals is allowed, as well as at a sufficiently inserted complete locking position at which the inserted connecting terminals are locked. Within the housing 3, there are formed two rows of terminal accommodating holes 28 each accommodating respective connecting terminals. The rear holder 4 is formed in a substantially plate-like shape and includes a main body 41 which is inserted into slits 29 of the housing 3 and locking arms 45 which are inserted into respective terminal accommodating holes 28. A width of a locking arm 45 is slightly smaller than that of a terminal accommodating hole 28. Windows 37 are formed in the outer wall 21 of the housing 3 such that the terminal accommodating holes 28 are communicated with external through the windows 37. Through these windows 37, locking condition between the connecting terminals 2 and the locking arms 45 can be released and an electrical conduction test of the connecting terminals 2 can be performed.

    • A highly reliable fiber grating and its manufacturing method, wherein: as a core (2), in addition to Ge of an ordinary concentration equivalent to the concentration of the core of a connection object optical fiber, a core codoped with Sn and Al of predetermined concentrations is employed; a primary covering layer (4) made of ultraviolet ray transmitting resin which transmits an ultraviolet ray with a wavelength of 240 nm - 270 nm and, on the other hand, absorbs an ultraviolet ray with a wavelength in wavelength regions shorter than 240 nm and longer than 270 nm to be cured is applied to the core and the glass part (F) of a cladding (3); a grating is written by applying an ultraviolet ray to the outside of the primary covering layer; and a secondary covering layer (7) made of resin which has a negative linear expansion coefficient so as to cancel and suppress the elongation and contraction caused by the positive linear expansion coefficient of the glass part involving temperature change is applied to the primary covering layer; whereby the grating can be written without causing the deterioration of transmission characteristics and, in addition, both the transmission characteristics and mechanical characteristics can be satisfied at the same time while the improvement of productivity is not obstructed and, moreover, temperature characteristics can be stabilized.
