    摘要： A terminal fitting (30) has a rectangular tubular main body (31) with a ceiling wall (33), first and second sidewalls (34, 35) extending down from the opposite sides of the ceiling wall (33), a bottom wall (36) projecting from the first sidewall (34) to face the ceiling wall (33), and an outer wall (37) projecting from the second side wall (35) and placed on the outer side of the bottom wall (36). A front-portion holding piece (50) projects from a front portion (37a) of the outer wall (37) and engages a front-portion holding groove (51) in the first sidewall (34). A restrictable projection (70) is provided at the rear end of the front-portion holding piece (50), and engages a restricting groove (71) of the front-portion holding groove (51) for restricting an opening deformation of the outer wall (37).

    摘要： A female housing (10) has cavities (11) into which female terminal fittings (30) are insertable from behind. A lock (13) projects forward from its base end and is restorable after being temporarily resiliently deformed by the female terminal fitting (30) being inserted, thereby engaging and locking the female terminal fitting (30) in the cavity (11). Maneuverable recesses (24) maneuverable by a disengagement jig (60) from front are provided at positions on the front surface of each lock (13) retracted from the locked terminal fitting (30) and within a width range of a locking surface of the lock (13) engageable with the terminal fitting (30) and located more toward the base end of the locking portion than the locking surface.

    摘要： A connector has a housing (10) with cavities (11) into which terminal fittings (30) are insertable. Locks (13) in the housing (10) deform during insertion of the terminal fittings (30) into the cavities (11), but then resiliently restore to lock the terminal fittings (30) in the cavities (11). Lowered portions (12a) of a bottom wall (12) of the housing (10) face the locks (12) and prevent the locks (13) from being excessively deformed. The bottom surface of each lock (13) has a convex arcuate surface (13c) and each lowered portion (12a) of the bottom wall (12) has a recess (12b) substantially conforming to the convex arcuate surface (13c) to accommodate the convex arcuate surface (13c) when the lock (13) deforms.

    摘要： A connector has a housing (1) and retainer mount hole (8) is open in the housing (1) from its bottom surface over to its opposite side surfaces. Upon being moved from a partial locking position to a full locking position, A retainer (7) can be moved from a partial locking position to a full locking position and is guided obliquely forward by guides (22-25). Thus, the retainer (7) can be constantly guided to a specified position regardless of a variation in the fitted position of the retainer (7) in the retainer mount hole (8) along forward and backward directions. Since the retainer (7) and terminal fittings (4) can constantly have a proper positional relationship, a problem of a varying function of the retainer (7) to detect the insufficiently inserted states of the terminal fittings (4) due to a variation in the fitted position of the retainer (7) can be solved.

    摘要： A retainer mount hole (10) is open in a connector housing (1) from its bottom surface over to its opposite side surfaces, and a retainer (35) is pushed obliquely from a partial locking position to a full locking position. On the other hand, each terminal fitting (25) is provided with a projection (28) and a stabilizer (29) at the side of the projection (28). When the retainer (35) reaches the full locking position, both the projection (28) and the stabilizer (29) are engaged with the retainer (35). The projecting end of the rear end of the stabilizer (29) is pointed, thereby forming a biting portion (56). When a wire (31) connected with the terminal fitting (25) is pulled backward, the biting portion (56) bites in the retainer (35) to prevent the retainer (35) from returning.

    摘要： A connector has a housing (10) with a cavity (11) and a resiliently deformable lock (13) in the cavity (11). The connector further has a terminal fitting (30) that can be inserted into the cavity (11). The insertion of the terminal fitting (30) deforms the lock (13). However, the lock (13) restores when the terminal fitting (30) is inserted completely, and locks the terminal fitting in the cavity (11). The terminal fitting (30) and the cavity (11) are formed with mutually engageable structures (53, 26) for preventing inclination of the terminal fitting (30) in the deforming direction of the lock (13).

    摘要： A connector housing (30) has a cavity (31) and a resiliently deformable lock (40) cantilevers forwardly from a wall (35) of the cavity (31) for engaging a locking surface (24) of a terminal fitting (10) inserted into the cavity (31). A base end of the lock (40) has a thinned portion (52). A backward pulling force on the female terminal fitting (10) creates a compressive force on the lock (40) in the longitudinal direction. Thus, the lock (40) undergoes such a resilient deformation at the thinned portion (52) that the length (L1) of the lock (40) becomes shorter than its natural length (L0). Buckling strength is enhanced by as much as the lock (40) is shortened and, as a result, a force for locking the female terminal fitting (10) is enhanced.

    摘要： A wavelength dispersion probing system for determining a value of wavelength dispersion and its sign and reducing the trouble and time required for this determination. This wavelength dispersion probing system comprises light sources 10, 12, light attenuators 14, 16, optical multiplexer 18, phase modulator 20, optical amplifiers 22, 26, acoustooptical modulator 24, optical receiver 30. The intensity ratio of two wavelengths is set at 1 to 2 to detect Stokes light or anti-Stokes light included in the return light of an optical fiber 100 by the optical receiver 30, so that wavelength dispersion is probed. The wavelength dispersion is probed by changing the intensity ratio of the two wavelengths to observe the state of the change of the wavelength dispersion, so that the sign of wavelength dispersion is determined by the optical receiver 30.
