Description of the Invention: [Technical Field] The present invention relates to an electrical connector, and more particularly to an electrical connector having a locking member that prevents unintentional disconnection of a counterpart connector. [Prior Art] Such an electrical connector is known, for example, as disclosed in Patent Document 1. φ The connector of Patent Document 1 has a locking member that is attached to the outer wall of the outer casing. The lock member is formed by bending a metal plate in a thickness direction, and has a mounted portion that is attached to the outer wall and a flexible portion that is spaced apart from the mounted portion. The attached portion is a flat-shaped held portion that is inserted into a slit formed in a protruding wall formed on an outer wall of the outer casing, and a tongue-shaped cutout portion that is cut out from the outside of the slit, and the lower end edge of the cutout portion is Abuts against the upper surface of the protruding wall forming the slit. On the other hand, the flexible portion is elastically deflectable toward the side of the held portion, and has a locking hole for locking the connector with the other side in the intermediate portion and an operating force for applying the deflection. Operation department. When the flat-shaped held portion is inserted into the slit, the slit portion is abutted from the upper surface of the protruding wall by the slit, and is prevented from coming off downward (the connector side). Further, in the opposite direction, the bent portion between the flexible portion and the held portion abuts against the lower surface of the protruding wall to prevent falling off. [Patent Document 1] JP-A-2008-004447 201025756 [Problem to be Solved by the Invention] In the locking member of the connector of Patent Document 1, the upper portion is detached because the curved portion is protruded from the outer casing. The lower surface of the wall abuts so that it is sufficiently prevented, but when a large force acts on the locking member downward, it is necessary to resist the above force only by the notched portion that abuts against the upper surface of the protruding wall. The slit portion is subjected to this force by the lower end edge to generate a compressive stress, and because of a certain inclination, it is also likely to be bent along with the bending stress. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ I can't expect it at all. In view of the above circumstances, an object of the present invention is to provide an electrical connector that does not easily fall off even when a large force is applied downward, and that has a locking member that does not cause damage such as bending. (Means for Solving the Problem) The electrical connector according to the present invention includes a housing that is formed to be housed in the counterpart connector, and a housing that is formed to be open at one end side, and a contact portion is disposed in the housing portion A terminal that is held by the outer casing and a locking member that is attached to an outer wall of the outer casing that extends toward the fitting direction of the connector. In the present invention, the above-mentioned locking member is characterized in that the locking member has a leg portion which is formed by bending a metal plate from the other end side of the outer casing toward the thickness direction and is provided on both sides of the curved portion. The one leg portion is formed to be attached to the outer wall of the outer casing. The other leg portion is formed. -6- 201025756 The mounting portion has the one end side and is penetrated by the flexible portion and the orientation. The holding portion is formed by pressing the outer card so that the protruding force of the connector housing toward the one end side is such that the force of the lock locking member passes through the slit side. The flexible portion that is elastically deflectable toward the attached portion due to the problem of the bending is placed toward the through portion of the protruding wall formed on the outer wall toward the held portion that is penetrated and held by the through slit. The locking portion that is engaged with the locking projection of the outer wall outside the slit has an operation portion that receives the pressing operation in the direction of locking the outer wall that is locked with the corresponding portion of the counterpart connector, and the above-described locking is formed. The surface of the portion is directed toward the flexible portion toward the Φ pressed portion, and the pressed portion is urged toward the outer wall by the inner wall surface of the through slit, and the locking portion is a locking hole locking hole. The edge is locked with the locking projection. In such a connector, when the other connector is inserted and removed, the other end side (the front connector insertion direction is forward) and the (pull-out direction) receives the force from the counterpart connector. In the lock member of the present invention, the bending portion is brought into contact with the lower surface of the wall against the force on the one end side to prevent the falling portion, and the locking hole toward the other end side φ member is locked with the locking projection of the outer casing, and is The holding portion is strongly pressed against the pressed portion in the thickness direction and is pressed into the upper portion. In the present invention, the locking member is biased toward the other end, and the force acts on the edge of the locking hole, which is pulled around the periphery, which is different from the case produced by the conventional slit, and no further, in the present invention In the middle of the 201025756 outer wall, the locking member is biased from the inner wall surface of the slit by the force of the pressed portion, and the locking portion of the locking portion is not provided. In the present invention, the attached portion has a claw portion formed on the side edge, and the claw portion may be a corresponding portion that engages the outer casing. Thereby, the detachment of the lock member toward the one end side of the curved portion is prevented, and the detachment of the other end side by the nip and the locking hole is prevented, and the one end side and the other end side are prevented. The shedding of one side can also improve the prevention effect. In the present invention, it is preferable that the outer casing has a restriction portion that determines the flexibility of the locking member to the maximum separation position of the portion to be attached. The locking member is naturally restricted by the outer wall of the outer casing in a direction toward the outer wall, but in the direction away from the outer wall, that is, in the direction in which the mounted portion is separated, excessive displacement is caused by the restricting portion. Is limited. In the present invention, the locking member is preferably such that the locking portion is engaged with the counterpart of the counterpart connector from the inside. Thereby, in the fitting state of the counterpart connector, since the lock portion of the lock member is not exposed to the outside, it is possible to avoid the situation in which the lock is released by the unintentional force. @ In the present invention, the operating portion of the locking member is preferably protruded outward from the restricting portion of the outer casing. Thereby, when the lock is released, the pressing force can be easily applied to the operation portion. [Effects of the Invention] As described above, the pressure-receiving portion provided in the holding portion of the lock member is strongly urged from the inner wall surface of the slit by the thickness direction, so that the pressure effect is large and can be surely prevented. The downward force is detached, and the force received by the embossed portion -8-201025756 is urged toward the outer wall surface of the outer casing. Therefore, the locking hole as the locking portion does not fall off from the locking projection. At this point, it is also possible to surely prevent the falling down. Further, although the force is applied upward from the locking projection in the edge portion of the locking hole, since this causes a tensile force to be applied around the locking hole and does not receive a compressive force, bending does not occur. . [Embodiment] Hereinafter, an embodiment of the present invention will be described based on Figs. 1 to 5 of the drawings. Fig. 1 is a perspective view showing the appearance of the connector 1 and the counterpart connector 2 of the present embodiment. The connector 1 of the present embodiment has a housing 10 made of an electrically insulating material, a terminal 20 held by the housing 10, and a locking member 30. In the housing 10, the outer shape is formed into a substantially rectangular parallelepiped. The accommodating portion 11 in which the above-described counterpart connector 2 is housed from the upper Φ side. The accommodating portion 11 corresponds to a pair of side outer walls 12 and 13 extending in the longitudinal direction, and end walls 14 and 14 and the bottom wall 10A connecting the outer walls 12 and 13 at both ends (Fig. 4) Referring to), a concave portion that opens upward is formed. In the present embodiment, the outer wall 12 on one side is provided with a protruding wall 15 that protrudes outward from the lower portion at the center position in the longitudinal direction (refer to FIG. 3). In the longitudinal direction, the protruding wall 15 is provided. In the two end positions, as shown in Fig. 3, which omits the locking member 30 and only the outer casing 10 is shown, the two restricting walls 16 which are outwardly extended toward the outer side -9-201025756 and which are extended upward and downward are phased in the longitudinal direction. Face the settings. The restricting wall 16 is at an upper position at the front end of the projecting direction, and is provided with a projecting restricting portion 16A that faces the direction of the other restricting wall 16 facing each other. A projecting portion 16B is formed at a position of the base portion of the restricting wall 16, that is, at a boundary position with the outer wall 12, and a range of the projecting wall 15 is vertically opened in a range between the projecting portions 16B in the longitudinal direction. Seam 17 (see also Figure 4). The inner wall surface of the outer wall 12 close to the through slit 17 is formed into the same flat surface as the surface of the outer wall 12. Further, as shown in Fig. 3, in the longitudinal direction, a locking projection 18 extending in the longitudinal direction is provided between the two projecting portions 16A at a position further above the protruding wall 15 in the outer wall 12. . This locking projection 18 projects upward as shown in Fig. 4. In the present embodiment, the upper surface forms an acute angle with respect to the surface of the outer wall 12, and the lower surface forms an obtuse angle. Further, in the longitudinal direction, the locking projection 18 is shorter than the formation range of the through slit 17 (refer to Fig. 3). A terminal 20 is disposed in the space of the housing portion 11 of the outer casing 10. The terminal 20 is disposed along the inner faces of the outer walls 12 and 13 in the longitudinal direction, and almost all of the terminals 20 are housed in the space of the housing portion 11 to form two rows. Each of the terminals 20 is formed in a plate shape, and the plate surface is a direction in which the terminals are arranged, that is, a surface forming a right angle with respect to the longitudinal direction. The terminal 20' has a contact portion 21 located in the accommodating portion n and a connecting portion 22 projecting from the bottom wall 15 of the casing 10 toward the outside (refer to Fig. 4). -10-201025756 Next, the lock member 30 is formed by punching a metal plate, for example, by punching, and then bending it in the thickness direction. As shown in FIG. 1 and FIG. 2(A), (B) and FIG. 4, the locking member 30 has the curved portion 31 as a bottom portion and two leg portions extending upward, and one leg portion is formed. The attached portion 32 and the other leg portion form the flexible portion 33. The mounted portion 32 is attached to the outer wall 12 of the outer casing 10, and the flexible portion 33 is secured to the mounted portion 32 in a separated state. The φ to-be-attached portion 32 has a pressure-receiving portion 3 2A that is partially protruded toward the flexible portion 33 side, and a locking hole 32B that is formed as a locking portion at an upper portion thereof. The above-mentioned pressed portion 32A is a vertically elongated projection in the present embodiment, but the shape and number thereof are not limited thereto. The amount of protrusion in the thickness direction of the pressed portion 32A is such that the portion where the pressed portion 3 2A is formed enters the through slit 17 of the outer casing 10 and enters a degree of press-fitting that can obtain a sufficient compressive force. . The attached portion 32 is a held portion in which the φ is held by the through slit 17 in a range existing in the through slit 17. The locking hole 32B has a size that protrudes from the through slit 17 and is located above the through slit 17 when the portion in which the pressed portion 32A is formed is pressed into the through slit 17 . Further, the upper edge of the opening of the locking hole 32B is locked at a position of the locking projection 18 provided on the outer wall 12 of the outer casing. Further, the attached portion 32 is at a position corresponding to the range of the pressure-receiving portion 3 2A in the vertical direction, and the two claw portions 3 2C are provided on both side edges. The width of the attached portion 32, that is, the distance between the side edges of the both portions is substantially equal to the distance between the both projecting portions 16B. -11 - 201025756 The flexible portion 33 extends until it is above the mounted portion 32, and is wider at the intermediate portion than the mounted portion 32. In the lower portion, the notch groove 33A is formed on both sides, and a base portion having the same width as the above-described mounted portion 32 is formed, and the flexible portion 33 is easily deflected in the thickness direction. In the intermediate portion having a wide width, an operation portion 34 formed to be greatly bulged outward is provided. The amount of bulging outside the bulging portion 34 is preferably protruded outward from the position of the regulating portion 16A when the attached portion 32 is attached to the outer wall 12. The flexible portion 33 has a width larger than that of the intermediate portion, and an inclined portion 35 is formed at a portion near the upper end edge. Further, a locking portion 36 having a window-like opening is formed between the inclined portion 35 and the operation portion 34. The lock portion 36 is locked with a corresponding portion of a counterpart connector to be described later to perform locking for preventing the disconnection of the counterpart connector. This locking member 30 is mounted for the outer casing 10 from below. This mounting is performed by inserting the mounted portion 32 of the locking member 30 toward the through slit 17 of the outer casing 10. Since the to-be-depressed portion 32A is formed in the attached portion 32, when the insertion is made toward the through slit 17, the pressed portion 32A is compressed to bring the mounted portion 32 into a pressed state. Since the pressed portion 32A protrudes to the left in Fig. 4, it is pressed toward the right from the left inner wall surface of the through slit 17, i.e., toward the outer wall 12 of the outer casing 10. The press-fitting is continued until the curved portion 31 reaches a predetermined position abutting against the bottom surface of the protruding wall 15 of the outer casing 10. When the predetermined position is reached, the upper portion of the attached portion 32, that is, the portion in which the locking hole 32B is formed, protrudes upward through the through slit 17, and the locking hole 3 is made elastic according to the thickness direction thereof. The upper edge of 2B is locked to the locking projection 18 by the lower end of the locking projection 18 from the lower side 201025756. Further, in the attached portion 32, when pressed, the claw portions 32C on both side edges are engaged with the inner surface of the regulating wall 16 and maintained at the predetermined position. In this manner, the lock member 30 is prevented from coming off by the abutment of the curved portion 31 and the protruding wall 15 toward the upper side of the claw portion 32C, and is prevented from coming off downward, and is penetrated toward the pressed portion 32A downward. The press-fitting of the slit 17 and the locking of the locking projection 18 toward the locking hole 32B and the insertion of the restricting wall 16 of the claw portion 32C further prevent the φ from falling off. In the connector 1 of the present embodiment, the counterpart connector 2 is the outer shape of the housing portion 11 having the housing 10 adapted to fit the connector 1 described above, as shown in Fig. 1, in which the housing is In one side wall 41 of one of 40, a protruding portion 42 that protrudes laterally is provided. The casing 41 is provided with two rows of terminal holes 43 corresponding to the arrangement positions of the terminals 20 of the connector 1, and a terminal 44 for crimping the cable C is held in each of the terminal holes 43. Each of the terminal holes 43 penetrates vertically, and the cable φ extends upward, and the contact portion 21 of the terminal 20 of the connector 1 can enter from below. The outer casing 41 is formed with a slit in a part of the outer wall portion of each of the terminal holes 43', whereby the slit is provided with a flexible slit portion 45. In the terminal hole 43, the inner surface of the tapered surface of the notch portion 45 is narrowed in width, and the deep portion (lower portion of the figure) of the terminal hole 43 is narrower than the upper portion. The space between the lower end of the notch portion 45 and the lower portion of the outer wall of the terminal hole 43 is a space for forming a locking portion of the terminal. In the protruding portion 42 provided in the outer casing 41, a hole 13-201025756 which is vertically penetrated is formed, and an upper portion of the flexible portion 33 of the locking member 30 of the connector 1 can enter the receiving hole 46. The edge portion near the outer side among the inner peripheral edges of the lower side of the receiving hole 46 is a locking projection 47. The upper surface of the locking projection 47 is inclined toward the front end toward a plurality of upwardly to form a fishing shape. When the connector 2 is fitted to the connector 1 described above, the locking projection 47 abuts the inclined portion 35 of the distal end portion of the flexible portion 33 of the lock member 30, and the flexible portion 33 faces the distal end. The inner side is deflected so that the flexible portion 33 can be guided further into the receiving hole 46 of the flexible portion 33. The locking projection 47 is configured such that when the connector 2 is fitted into the connector 1 until a predetermined position, the locking portion 36 and the opening portion of the flexible portion 33 are aligned, and the elastic deflection toward the flexible portion 33 is achieved. The release direction is returned, and the locking portion 36 of the flexible portion protrudes into the lock portion 36 for locking. The press-fit terminal 44 itself is known, and is formed by a metal plate to form a nip portion 44A having a cable core, a cable covering holding portion 44B, a contact portion 44C, and a locking portion 44D. The core wire of the cable C which is covered and removed by the front end side is pressed by the clamp of the nip portion 44A, and the cable is covered and the cable covering holding portion 44B is held by the clamp. Further, the locking portion 44D is formed in a protruding shape that protrudes laterally and is locked to the lower end of the cutout portion 44 to prevent the terminal 44 of the cable from coming off. The contact portion 44C has two tongues extending downward, and a throat is formed between the tongues, whereby the contact portion 21 of the terminal 20 of the connector 1 that enters below is pressed to achieve electrical connection. Next, the use of the connector of this embodiment will be described. (1) The connector 1 is placed on a predetermined circuit board (not shown -14 - 201025756), and each terminal 20 is connected by soldering the connection portion 22 to the corresponding circuit portion of the circuit board. (2) The counterpart connector 2 is in a state where the cable C is connected to each terminal 44. The terminal 44 is inserted into the terminal hole 43. The locking portion 44D of the terminal 44 is located at a position engageable with the front end (fourth end and the lower end) of the cutout portion 45 of the outer casing 41, and prevents the upwardly facing terminal 44 from coming off. (3) The connector 2 to which the cable terminal is inserted is placed at the upper position of the connector 1 as shown in Fig. 1, and is inserted into the connector 1 as shown in Fig. 4. At the initial stage of the insertion, the counterpart connector 2 is such that its outer casing 41 is guided by the accommodating portion 11 of the outer casing 10 of the connector 1, as shown in Fig. 4, the locking projection 47 of the outer casing 41 is connected to the connector 1. The inclined portion 35 of the upper end of the lock member 30 abuts. (4) After the locking projection 47 and the inclined portion 35 abut, the force for insertion is increased, and the counterpart connector 2 is pressed into the connector 1. The lock member 30 receives the force from the lock projection 47 by the inclined portion 35, and the force of the y-direction component is elastically deflected toward the inside of the connector by the two-point lock line of Fig. 5, allowing the counterpart connector 2 further entry. (5) When the counterpart connector 2 is further inserted, the locking projection 47 of the counterpart connector 2 is locked with the opening locking portion 36 by the predetermined insertion position, and the locking against the upper side of the counterpart connector 2 is prevented from being locked ( Figure 5 refers to). In the predetermined insertion position, the terminal 44 of the counterpart connector 2 receives and presses the contact portion 22 of the plate-like terminal 20 of the connector 1 in the contact portion 44C having the throat portion. Thus the connection of the connectors 1, 2 is completed. -15- 201025756 (6) In this manner, when the counterpart connector 2 to which the connector 1 is connected is pulled out from the connector 1, it is necessary to release the lock. In the unlocking of the lock, the operator presses the operation portion 34 of the lock member 30 toward the outer wall 12 of the connector 1. The flexible portion 33 of the lock member 30 pressed by the operation portion 34 is elastically deflected until the position of the two-point lock line as shown in Fig. 5, and the flexible portion 33 is generated. This state is maintained and the counterpart connector 2 is pulled up and pulled out. Further, since the operation portion 34 protrudes outward from the regulating wall 16A, the pressing force can be easily applied to the operation portion 34, and the lock can be released.
