The outer casing is provided with a locking portion, and the locking claw locking arm ' having the locking portion engaged with the aforementioned locking portion in the other outer casing is a wire harness that is assembled using a connector with a locking mechanism that may be flexibly bent by elastic deformation. At the time of assembly, the wiring harness is managed in a plurality of bundles. At this time, the electric wire bundled into the harness is wound around the lock arm and the outer casing of the connector, or is stuck, and the above-described lock arm or the like is deformed. SUMMARY OF THE INVENTION (Problems to be Solved by the Invention) An object of the present invention is to solve the above-mentioned problems and to provide a method for preventing a wire bundled into a wire bundle from being entangled or stuck when used in a wire harness. The locking arm is coupled to the mating connector of the locking mechanism. (Means for Solving the Problem) In order to achieve the above object, the present invention is constituted by a female connector and a male connector, and a locking portion is provided in one of the outer casings, and the outer casing is provided in the other housing -4 - (2) ( 2) 1327799 A locking arm having a locking claw that is engaged with the locking portion is flexibly provided by a hinge portion that is elastically deformable, and is characterized in that: a movable portion on a free end side of the locking arm and the aforementioned Between the outer casings of the other side, a connecting piece for cutting is provided, and the connecting piece is cut by the bending operation of the lock arm when the female and male connectors are fitted and connected. The connector of the present invention has a specific configuration in which the lock arms are formed in a pair, and each of the lock arms has a tip end portion that is bent to the outside with a hinge portion provided at a front end portion of the other outer casing. At the same time, the intermediate portion is inclined to extend toward the outer rear side, and the connecting piece is cut between the rear end portion on the free end side and the outer casing of the other side, and further, a retaining portion is formed at the rear end portion. When the male connector is fitted and connected, the rear end portions of the two lock arms are cut by the bending operation toward each other. The hinge portion of the above-described configuration is formed on the upper surface of the rear end portion of the outer casing of the other side, and is provided on both sides of the front end portion of the support arm extending in the vicinity of the front end. A preferred embodiment of the connecting piece is formed in a pyramid shape, the base end portion of which is integrally connected to the lock arm, and the tip end portion is integrally connected to the other outer casing, and is easy to Cut off is possible. In another embodiment of the connecting piece, the connecting piece is an elongated strip-shaped piece formed in a V-shape in plan view, and one end thereof is connected to an inner side surface of a rear end portion of each of the locking arms, and the other end is Connected to the side surface of the rear end portion of the support arm, when the mating connection of the female and male connectors is performed, the rear end portions of the two locking arms are bent toward each other: -5 - (4) (4) 1327799 The slit 17 of the contact 16 locks and holds the locking shoulder 6 protruding from the inner wall of the receiving portion 5 to become the female connector 1 of the wire harness. • A pair of locking arms 7, 7 are provided on the upper side of the outer casing 3. The two lock arms 7'7 are projecting portions 9 formed on the upper end portion of the rear end portion of the outer casing 3, and elastically deformable hinge portions 9 on both sides of the front end portion of the support arm 8 integrally formed in the vicinity of the front and rear of the outer casing 3. 9 bends may be connected. Each of the locking arms 7 has a front end portion that is bent to the outside of the hinge portion 9 and is open to the outside. At the same time, the intermediate portion is outwardly extended obliquely toward the outer rear side, and the rear end portion 10 on the free end side and the outer casing 3 Between the above is a possible connection piece 1 1 for cutting off. The outer side surface of the rear end portion 10 is formed with a grip 1 2 that protrudes in the lateral direction. Further, the outer side surface of the intermediate portion of each of the lock arms 7 is provided with a locking claw 1 3 that protrudes in the lateral direction. The locking claw 13 is a locking protrusion provided to the outer casing 4 of the male connector 2 to be described later. The part 25 is engaged. The connecting piece 11 has a short quadrangular pyramid shape as shown in Figs. 3 and 4, and the base end portion is integrally coupled to the lower surface of the rear end portion 10 of the lock arm 7, and the tip end portion 11a is the upper surface of the outer casing 3. It is easy to cut off at the same time. The outer casing 4 of the male connector 2 is a flat box shape having a fitting hollow portion 20 formed in the front opening as shown in Fig. 5 and Fig. 5 and Fig. 6, and penetrates the rear side wall 21 The plurality of pin contacts 2 2 are provided to protrude the fitting recess 20, and the reed portion 23 of each pin contact 22 is brazed to the surface of the printed circuit board 30 as a pin head. Male connector 2. Further, at both ends of the upper end portion of the front end portion of the outer casing 4, the locking projections 25, -7 - (5) (5) of the locking claws 13 and 13 of the lock arms 7 and 7 of the female connector 1 are engaged. 1327799 25 is formed integrally with the outer casing 4. In the above configuration, the female connector 1 and the male connector 2 are such that the front half of the outer casing 3 is inserted into the fitting hollow portion 20 of the fitting outer casing 4, and the plug contact member 16 and the pin contact member 2 2 are fitted and electrically connected. However, while the outer casing 3 is inserted into the fitting hollow portion 20 of the outer casing 4, the two locking arms 7, 7 are inserted between the two locking projections 25, 25, and if the outer casing 3 is further inserted, the two locking arms 7 and 7 are The locking claws 13, 13 abut against the two locking projections 25, 25. As shown in Fig. 7, the locking arms 7, 7 are bent inwardly with the hinge portions 9, 9 as fulcrums. With the bending operation of the two locking arms 7, 7, the two connecting pieces 11, 11 are cut by the tip end portions 1 1 a, 1 1 a. The force required for the cutting is small, and the bending action to the inside of the two locking arms 7, 7 can be easily cut, and the fitting operation of the female connector and the male connector 2 is hardly affected. 3 is further inserted and advanced, and when the mating connection of the female connector 1 and the male connector 2 is completed, as shown in FIG. 9 and the front view, the two locking arms 7 between the two latching projections 25' 25 are passed. 7 is enlarged outward by the elastic recovery force of the hinge portions 9, 9, and the two locking claws 13, 13 are engaged with the two engaging projections 25, 25 to lock the outer casing 3 and the outer casing 4. FIGS. 12 and 12 show another embodiment of the present invention, and the connecting piece 41 is formed by a V-shaped elongated strip-shaped sheet. The one end 42 of the connecting piece 41 is connected to the locking arm 7. The inner side of the rear end portion and the other end 43 are attached to the side of the rear end portion of the support arm 8. Further, the V-shaped bent portion 44 is severable. Then, as shown in Fig. 2, in the female connector 1 and the male connector 2 -8- (6) 1327799, the locking arms 7, 7 are inserted into the two locking claws 25, 25. The locking arms 7, 7 are followed by When the hinge portions 9 and 9 are inserted into the outer casing 4, the fitting recess 20 of the outer casing is bent in the middle of the passage between the two, and the bending portion 4 of the connecting piece 41 is bent. 4 cut off.
