Description of the Invention [Technical Field of the Invention] The present invention relates to an electrical connector for a cable. [Prior Art] A connector in which a terminal to which a cable is connected is mounted in a casing is fitted into a connector of a counterpart connector in a direction perpendicular to the longitudinal direction of the cable, and is disclosed, for example, in Patent Document 1. The terminal of the connector of Patent Document 1 is manufactured by buckling a metal plate, and has a small piece called a spear which is inclined in a direction opposite to the direction in which the casing is mounted. When the terminal is inserted into the predetermined position of the housing to the predetermined position, the end portion of the spear is locked to the inner surface of the locking hole of the housing, and the position of the fixed terminal is fixed and prevented from coming off. [Patent Document 1] Japanese Patent Laid-Open No. 2 0 0 2 - 3 3 1 5 0 [Problem to be Solved by the Invention] However, the position of the spear disclosed in Patent Document 1 is fixed, and in terms of strength, there is Improve the space. Since the spear is a part of the terminal, it is made of metal, but when it is made into a small piece, when the cable is applied by an unexpected pulling force, the spear is deformed or broken. In particular, the direction in which the spear extends is inclined by a certain amount in the longitudinal direction of the cable, so that it does not coincide with the direction of the pulling force, and the seat curve is easily generated. -4- 200919856 Even if the spear is made to be strong in order to avoid the aforementioned problems of the spear, the shell will be subjected to a powerful force by the spear. Since the strength of the material itself is lower than that of the metal due to the casing, it is easy for the spear to abut against the casing with its cut end, so that the force on the shell is concentrated, and the damage becomes more conspicuous. The present invention has been developed in view of such circumstances, and provides an electrical connector for a cable which is capable of sufficiently receiving the cable even if the cable is inadvertently received after the terminal is mounted and the connector is used. There is no damage to the connector, and the position is fixed. [Means for Solving the Problem] The electrical connector for a cable according to the present invention is a terminal to which a cable is connected, and is fitted to the front side of the cable in the longitudinal direction of the cable, and is fitted at a right angle to the front-rear direction. The fitting direction contact portion is in elastic contact with the counterpart terminal. In the cable electrical connector of the present invention, in the fitting state of the connector, the terminal has a portion extending toward the front-rear direction and the fitting direction at a position further forward of a part of the counterpart terminal; The extending portion is bent in the direction of the thickness thereof and is deformed, and the restricted surface formed on the rear surface of the restricted portion and the regulating surface formed on the front surface of the opposite portion face each other in at least one direction. When the cable is pulled toward the rear, it is abutted by the restricted surface. It is damaged by sufficient resin. The special body should be clearly shown, and the purpose is to draw the casing, and the terminal metal plate can be made to face, and the limit of the plate-like extension of the terminal of the terminal connected to the other end is limited. Restricted surface-5-200919856 According to the present invention, the terminals of the mutual connectors form a restricted surface and a regulating surface, and the abutting of the two is performed by metal, so that the withstand voltage is large even in the connector. In the fitted state, the cable is pulled and the terminals are not deformed or damaged. Further, since the restricted portion is formed by the deflecting portion, the strength of the restricted portion itself is increased by the shape of the deflected portion. Further, by biasing the shape portion, the cable before assembly of the connector does not enter the contact portion, and entanglement can be prevented. In the present invention, the restricted surface is formed to be in contact with the restricting surface of the front end surface of the plate-like regulating portion formed on the counterpart terminal. The restricted surface is in contact with the regulating surface of the front end surface of the plate-shaped regulating portion of the counterpart connector. However, since the distal end surface of the restricting portion has only a contact area corresponding to the thickness of the plate, the restricted surface can be surely Abut. At this time, since the restricting portion receives the stress along the plate surface, the strength thereof is large. In the present invention, it is preferable that the extending portion and the restricted portion form a portion of the tubular portion extending in the front-rear direction, and the restricted surface is formed by the rear end surface of the tubular portion. According to this configuration, since the tubular rear end surface of the tubular portion forms the restricted portion, the strength of the tubular portion itself is increased, and the stress when abutting against the regulating portion is along the side surface, so that the endurance is increased. Further, since the rear end surface of the sound tube portion can largely ensure a possible contact area with the restricting portion, it is easy to correspond to the positional deviation of the restricting portion and also prevent the cable from being entangled before the connector is assembled. When the restricted surface is located at the position intersecting the regulating surface of the front end surface of the plate-like regulating portion when it is in the front-rear direction, when the cable is pulled, the restricting portion and the restricted portion can reliably abut. -6-200919856 In the present invention, the extending portion and the restricted portion form a groove-shaped portion that extends in the fitting direction of the connector and opens toward the front, and the restricted surface can be formed in the groove-shaped portion. Behind the bottom wall. The area behind the bottom wall is widened to ensure that the possible area is abutted, and the strength of the two side walls of the groove portion is increased. According to the present invention, when the terminal has a sub-cylindrical portion adjacent to the contact portion on the side opposite to the side of the restricted portion in the front-rear direction, the sub-cylindrical portion can be further confirmed. The entanglement of the cable before assembly of the connector is prevented. [Effect of the Invention] As described above, since the restricted portion is provided in the deflecting portion of the terminal of the electrical connector for the cable, the cable crimped and connected to the terminal is inadvertently fitted in the fitting state with the counterpart connector. At the time of drawing, the restricted portion formed in the deflecting portion abuts against the regulating portion of the counterpart terminal, so that the metal is in contact with each other, and the force can be sufficiently received without damaging the casing. Further, since the restricted portion is formed in the deflecting portion, the strength of the restricted portion itself is increased in accordance with the shape thereof, and the range in which the restricting portion can abut is widened, and even if there is a slight positional shift, Formed as a true abutment. Further, since the restricted portion is formed in the deflecting portion, when a plurality of terminals of the cable are connected and stored in a state before the connector is mounted, the deflecting portion is in contact with the other terminal. The other terminal portions or the cables are less likely to enter between the groove-like contact portions. It is possible to prevent the occurrence of entanglement of the cables that cause the terminals or other terminals, and the time required to separate them. 200919856 [Embodiment] Hereinafter, embodiments of the present invention will be described based on the drawings.

The crimping portion 22 is smaller than the grip portion 21, but similarly extends in the shape of an inverted U-shaped leg. By rounding the front end portion of these members, the core wire C1 of the cable c is pressed as shown in FIG. Connect the link. The locking leg portion 23 extends in an inverted U-shaped leg to reach the position of the inner wall surface 13B of the casing 11. The supported portion 24 is formed in an inverted U-shaped leg shape shorter than the locking leg portion 23, and the front end portion thereof is bent at a right angle toward the inner side, and is supported by the lower surface of the front end portion on the corresponding surface of the casing 11. The contact portion 25 is formed in a slightly inverted U-shaped leg shape which is narrowed downward and then widened, and the reduced-diameter portions 2 5 A receive the plate-shaped contact portions of the counterpart terminals and are in contact with each other. The restricted portion 26 provided adjacent to the contact portion 25 in front of the contact portion 25 is a plate shape extending downward in the shape of an inverted U-shaped leg as shown in Fig. 3 (A) and Fig. 3 (B). The front end sides (lower end sides) of the two extending portions 27 are formed by portions which are deflected toward and protruded toward the inner side. This protruding portion is not limited to the flat end faces, and can be engaged with each other in an arbitrary shape. The extending portion 27 and the restricted portion 26 form an angular cylindrical portion 28 extending forward and backward. That is, the restricted portion 26 is the bottom wall of the angular cylindrical portion 28. Further, the rear end surface forming restricted surface 26A of the restricted portion 26 has a positional relationship with the front end surface of the counterpart terminal in the front-rear direction, and the cable C is pressure-bonded to the terminal 20, and the terminal 20 is inserted. The terminal to the housing is inserted into the hole 13 . When the insertion is performed, the lower end side of the locking leg portion 23 of the terminal 2A is pressed downward toward the lower wall 17 of the casing 11, and then the thin portion 17B of the wall 17 is flexibly deformed in the lower-10-200919856 and exceeds the lower portion. The wall 17 is housed in the front housing portion 14, and the inner wall surface 13B of the opening 13A which is the front end surface of the lower wall 17 which is restored to the original shape is abutted, and the rear end surface of the locking leg portion 23 abuts to prevent the terminal 20 from coming off. As shown in FIG. 1(A), the terminal connector 30, which is fitted and connected to the connector 10 having the cable terminal 20, is held by the housing 31 formed with the receiving recess 32 opened upward. The bottom wall 31A. The receiving recess 32 is formed by a bottom wall 3 1 A and a peripheral wall 3 1 B adapted to receive the shape of the connector 10. The peripheral wall 3 1 B is cut on the rear side, and is cut for the space of the cable C extending toward the rear of the moving member 16 of the connector 10 toward the rear of the casing, but on both sides in a direction perpendicular to the paper surface thereof A tapered pressing wall 33 is formed. The pressing wall 3 3 interferes with the rear end surface 16C of the moving member 16 when the connector 10 is fitted into the connector 30 in a state where the moving member 16 of the connector 10 is not inserted into a predetermined advanced position. The pressing force toward the front is applied to the rear end surface 16C to automatically press the moving member 16 to a predetermined forward position. The movement of the moving member 16 up to the predetermined forward position means that the locking leg portion 23 of the terminal 20 of the connector 10 is surely housed in the front housing portion 14. As shown in FIG. 3(A), the terminal 40 also has a flat-shaped contact portion 41 extending upward and a front protruding portion 42 projecting upward from the front side, which is formed by buckling the metal plate. Concave 43. A front base portion 44 is provided below the recessed portion 43, and a connecting portion 45 whose lower end is bent at a right angle extends. On the rear side of the front base portion 44, -11 - 200919856 is provided with a central base portion 46 and a rear base portion 47, and a fixed portion 48 bent at right angles is formed by the lower V of the rear base portion 47. The fixing portion 48 and the connecting portion 45 are located at substantially the same horizontal position in the vertical direction. The front base portion 44, the center base portion 46, and the rear base portion 47 are connected in a flat plate shape having the same surface as the contact portion 4 1 and the front projection portion 42. A mounting groove portion 49 that is opened downward is formed between the base portion 44 and the center base portion 46, and a mounting groove portion 50 that is opened downward is formed between the center base portion 46 and the rear base portion 47. . The inner peripheral edge of the mounting groove portion 49' 50 is provided with a locking projection 49A' 50A °, and the front end portion 42 and the contact portion 41' are in the front-rear direction, respectively, corresponding to the aforementioned connection. The position of the restricted portion 26 of the terminal 20 of the device 1 and the contact portion 25. Therefore, the front end surface of the contact portion 4 1 of the terminal 40 forms a regulating surface 4 1 A which is mutually restricted in the front-rear direction with respect to the restricted surface 26A of the rear end surface of the restricted portion 26. Therefore, the contact portion 41 is also a restricting portion in which the regulating surface 4 1 A is formed on the front end surface. The terminal 40 is engaged with the locking groove portions 49, 50, and is engaged with the locking walls 31C, 31D protruding from the upper surface of the bottom wall 31A of the casing 31, and the locking projections 49A, 50A bite into the locking walls 31C, 31D. And being fixed. Thus, the connecting portion 45 and the fixing portion 48' of the terminal 40 mounted on the housing 31 are protruded downward by corresponding openings formed in the bottom wall 3 1 A of the housing 31, and are located below the bottom wall 3 1 A horizontal position. Next, when the connector 10 of the present embodiment is fitted and coupled to the counterpart connector 30, as shown in FIG. 1(B), the fitting portion 12 of the connector 1A is housed in the connector 30. The recess 3 2 is received. In this state, the terminal 20 of the connector -12-200919856 and the terminal 40-contacting portions 25, 41 of the connector 30 are in elastic contact with each other, and the restricted portion 26 is located in the recessed portion 43, the rear end surface of the restricted portion 26 The restricted surface 26A and the regulating surface 41A of the front end surface of the contact portion 41 are in the near position and face each other in the front-rear direction (see also FIG. 2(B)). In Fig. 1(B), the restricted surface 26A extends in a direction perpendicular to the plane of the paper, and the regulating surface 41A extends in the vertical direction. Therefore, when viewed from the front-rear direction, the restricted surface 26A and the regulating surface which extend linearly 41A cross positional relationship. Therefore, when the cable C of the connector 10 is inadvertently pulled toward the rear in a state in which the two connectors 1 and 30 are fitted and connected, the connector 10 is moved rearward to correspond to the connector in the front-rear direction. The amount of 30 shaking. According to this movement, the above-mentioned restricted surface 26A of the terminal 20 of the connector 10 abuts in a positional relationship with the above-mentioned restriction surface 4 1 A of the terminal 40 of the connector 30. The terminal 40 is strongly held in the casing 31, and the regulating surface 4 1 A of the terminal 40 limits the aforementioned restricted surface 26A by metal contact, and therefore, even if the cable C is subjected to considerable force pulling, There is a situation in which the aforementioned terminals 20, 40 are separated from each other and damaged. Moreover, there is no influence on the electrical contact of the terminals 20, 40 with each other. In the present embodiment, the restricted portion 26 of the terminal 20 of the connector 1 is formed as a part of the tubular portion 28, so that the strength is high. Further, the contact portion 41 having the regulating surface 41A of the terminal 40 of the connector 30 receives the reaction force from the restricted portion 26 in the direction of the plate surface of the contact portion 41, so that the strength is high. Further, in general, the thickness of the material of the terminal 20 of the connector 1 is also large, and the strength can be sufficiently ensured. In the above-described embodiment, the tubular portion 28 having the restricted portion 26 is extended in the front-rear direction as shown in Fig. 3 (B), and the rear end surface of the bottom wall portion is defined as the restricted surface 26A. As shown in Fig. 3(C), the restricted portion 26' is biased toward the inner side (the lower end side) of the two plate-like extending portions 27' extending downward, and is biased toward the inner side and superposed on the upper and lower sides. In part, a projection is formed at the front end of the upper extension portion, and an opening is formed at the lower extension portion to fit the two. In this case, the tubular portion 28' having the restricted portion 2'' can be formed to extend in the front-rear direction, and the rear end surface 26'A of the bottom wall portion can be formed as the restricted surface. In this case, since both of the extending portions are fitted and the area of the regulating surface is widened, the strength can be sufficiently ensured. Further, as shown in FIG. 3(D), the rear side of the two plate-like extending portions 27" extending downward by the restricted portion 26" may be biased by the inwardly facing buckling, and may extend in the vertical direction. The fitting direction of the connector forms a groove-shaped portion 29 that opens toward the front, and the rear wall of the connector is formed as a restricted surface 26"A. In any of Figs. 3(B), (C), (D) In this case, since the restricted surface is formed in the portion that is connected to the portion that is deflected by the buckling, the strength can be sufficiently ensured. In the present embodiment, the tubular portion and the groove-shaped portion are formed in this manner, and a part thereof is restricted. Therefore, as described above, the abutment with the counterpart terminal can be made more reliable, and the strength can be improved, and the plurality of collective storages are adjacent to the contact before assembling the cable terminal into the connector. The cylindrical portion and the groove-shaped portion prevent the cable from entering between the two sheets forming the contact portion. Therefore, when one cable terminal in the stock is taken out, the other cable entangled terminal with the cable terminal Seduce each other also -14-200919856 In the embodiment shown in Fig. 1 and Fig. 2 (A), the tubular portion 28 is provided adjacent to the front side of the contact portion 25, and the restricted portion 26 is formed on the bottom wall thereof so as to be adjacent to the rear of the contact portion 25. The supported portion 24 is formed in a slightly inverted U-shaped leg shape. However, the supported portion 24 may be abutted against the front end, and the tubular portion 28 may be added to the supported portion 24 When the sub-cylindrical portion is formed, the bottom portion of the sub-cylindrical portion functions as a supported portion supported by the casing, and the tubular portion 28 and the sub-cylindrical portion are in contact with each other. The front and rear of the portion 25 can effectively prevent the cable or the terminal from being entangled with each other.
