Abstract: A connector plug can be removably snap-fitted into the adapter which has a cavity into which the connector plug is inserted and a hole for locking the connector plug. The connector plug has: an optical fiber; a ferrule; housing; an elastic engagement piece with an projecting engagement portion and a projecting press portion, the engagement portion being adapted to snap into the hole of the adapter and become locked there when the connector plug is inserted into the adapter; and a stopper for locking the elastic engagement piece from being pressed. A height of the projecting press portion is set almost flush with a surface of the housing of the adapter, or is set almost equal to the height of the receptor portion of the adapter. Therefore, the connector plug can easily be connected to and disconnected from the adapter and its connection with the adapter is not easily broken.

Abstract: An electrical connector A has a connector housing (10) with a locking arm (11) formed integrally with an outer surface of the connector housing(11). A thickness Tk of a base part (12) of the locking arm (11) is set larger than a thickness Ta of an arm part (13) thereof. Thus, the flexure rigidity of the base part (12) is greater than that of the arm part (13). When the locking arm (11) tilts in away from the connector housing (10), with the base part (12) acting as the supporting point of the tilting motion of the locking arm (11), the degree of the strain of the base part (12) is low. This is because the base part (12) is less flexible than the arm part (13). A force of tilting the locking arm (11) is relaxed by elastic deformation of the arm part (13), which is more flexible than the base part (12). A stress generated by the tilting of the locking arm (11) does not concentrate on the base part (12), but is dispersed in the arm part (13). Thus, it is possible to prevent the base part (12) from being broken.

A central drain channel 15, 35 runs through the center of each housing 10, 30 and is sealed by means of mutually fitting tapered faces 26A, 46A. Overhanging hoods 14a, 14d shield the mating faces and rear ends of the connector housings. Mating terminal chambers 11, 31 also have tapered sealing faces 28, 48. A peripheral rib 45 on one housing 30 fits into a groove 25 on the housing with a long narrow clearance to prevent moisture creep. Drain channels 15, 35 engage one another at tapered mating faces 26A, 36A.

Abstract: A connector comprises a combination of a plug connector and a receptacle connector. The plug connector has a plug insulator provided with first plug-side engaging portions formed on opposite side walls thereof, and at least one second plug-side engaging portion formed on a part of the plug insulator that is parallel to a width direction of the plug insulator. The receptacle connector has a receptacle insulator provided with first receptacle-side engaging portions formed on opposite side walls thereof to be engaged with the first plug-side engaging portions, and at least one second receptacle-side engaging portion formed on a part of the receptacle insulator that is parallel to a width direction of the receptacle insulator to be engaged with the second plug-side engaging portion.

Abstract: An electrical connector is disclosed, designed for use with a telephone headset. The connector utilizes angled contacts for low insertion force, resulting in easier mating and longer life. The connector is provided with a latch that allows the connector to be uncoupled with a force roughly eight times the insertion force. Both halves of the connector have beveled edges on the upper surfaces only, allowing the connector to be aligned by tactile feel rather than visual inspection or by trial and error. Fine wires can be terminated on the connector contacts because the wires are accurately centered over insulation piercing points on the electrical contacts, and expansion of the wires in all directions is restricted as the piercing points penetrate the wire.

Abstract: In a connector locking structure, a locking protrusion 1b is formed on the upper surface of a flexible locking arm 1 of a male connector, and insufficient engagement preventing protrusions 1c are extended from both sides of the locking protrusion, the housing 2 of a female connector has a cut 8, into which the flexible locking arm is inserted, displacement preventing stoppers 8a are provided which are confronted with the cut 8 to support the insufficient engagement preventing protrusion, and in the housing 2, a locking confirming slider 3 having an engaging portion 3b which is to be engaged with the locking protrusion 1b is provided in such a manner that the locking confirming slider 3 is movable back and forth, being kept urged forwardly by springs 4.
