It is configured to transmit to the main board 25. Here, FIG. 4 shows a plan view of the entire cable pull-out prevention device 60, and as shown in FIG. 2 and FIG. 4, the board side attached on the other board 47 at the rear end side end of the harness H A rear end side cable connector 51 connected to the connector 49 is attached, and a front end side cable connector 53 connected to the board side connector 26 attached to the main board 25 is attached to the front end side end of the harness H. Yes.

  Now, in the harness H configured in this manner, it is possible to prevent unauthorized actions such as removing the distal end side cable connector 53 from the board side connector 26 and connecting a modified harness (not shown) to the board side connector 26. In addition, a cable removal prevention device 60 is provided to prevent the distal end side cable connector 53 from being pulled out of the board case 25 from the connector insertion hole 41.

  FIG. 5 shows a front view of the cable removal prevention device 60. The cable removal prevention device 60 is connected to the board-side connector 26 as shown in FIGS. 4, 5, and 6A, and is inserted into the connector insertion hole. A pull-out preventing member 61 is movably mounted on a harness H extending outward from 41. The pull-out prevention member 61 includes a first split member 62 and a second split member 72 that can be split into two parts, and a joint holding portion 75 that holds the first split member 62 and the second split member 72 in a joined state. Configured. The first divided member 62 is made of an insulating material such as resin, and is integrally formed by injection molding or the like. The first divided member 62 is attached to a plate-like main body portion 62a extending in the front-rear direction and both left and right side portions on the front end side of the main body portion 62a. A pair of arm portions 62b that are inclined obliquely outward and rearward toward the rear side, and a pair of rectangular protrusion portions 62c that are attached to the left and right side portions on the rear end side of the main body portion 62a and project in the left-right direction. Configured.

  An accommodation recess 62d that extends in the front-rear direction and accommodates the harness H is formed in an intermediate portion on the back side of the main body 62a. The arm portion 62b is inclined obliquely outward and rearward when no external force is applied from the outside, and is elastically deformed to the main body portion side when a force in the inner direction of the main body portion 62 is applied. Return to position. The main body portion 62a is formed to have a size that can pass through the connector insertion hole 41, and the arm portion 62b can be elastically deformed to pass through the connector insertion hole 41 when the main body portion 62a is inserted into the connector insertion hole 41. When it passes through the insertion hole 41, it expands outward and returns to its original state, and the tip of the arm portion 62b is configured to be positioned outside the connector insertion hole 41. A gap 63 having a size slightly larger than the thickness of the wall portion 20a of the substrate case 20 is formed between the tip end side end of the protruding portion 62c and the tip end of the arm portion 62b.

  6A shows a cross-sectional view of the portion corresponding to the arrow AA in FIG. 4C, and as shown in the figure, a rectangular recess 64 is formed on the upper surface side of the protrusion 62c. A locking portion 65 is provided at the center of the bottom of the recess 64 and extends downward from the lower surface of the first split member 62 and has a locking projection 65a at the tip. The locking protrusion 65a is a sagittal lance protruding outward in the left-right direction. The dimension L1 between the tip of the main body 62a shown in FIG. 4C and the tip of the arm 62b in a state of expanding outward is such that the tip-side cable connector 53 is connected to the board-side connector 26. The dimension is slightly smaller than the distance L <b> 2 between the rear end of the front end side cable connector 53 and the inside of the wall portion 20 a of the board case 20.

  As shown in FIG. 4A, the second divided member 72 has substantially the same configuration as the first divided member 62, and therefore the same aspect as the first divided member 62 conforms to the first divided member 62. A description thereof will be omitted, and only differences from the first divided member 62 will be described. In the figure, 72a indicates a main body portion of the second divided member 72, 72b indicates an arm portion of the second divided member 72, 72c indicates a protruding portion of the second divided member 72, and 72d indicates a second divided member. 72 shows an accommodating recess.

  A rectangular engagement hole 74 for locking the locking projection 65a of the locking portion 65 is formed at the center of the recess 73 of the protrusion 72c of the second split member 72. As shown in FIGS. 5 and 6A, when the housing recesses 62d and 72d of the first split member 62 and the second split member 72 are arranged so as to face each other and the two are joined to each other, the harness H is A harness insertion hole 77 having a rectangular cross section is formed, and the harness insertion hole 77 is formed slightly larger than the harness H. The distal end side cable connector 53 has a rectangular cross section and is formed in a shape larger than the harness insertion hole 77. As a result, the distal end side cable connector 53 cannot pass through the harness insertion hole 77. The cable removal prevention device 60 includes a removal prevention member 61, a distal end side cable connector 53, and a substrate case 20 having a connector insertion hole 41.

  Next, the operation of the cable disconnection prevention device 60 will be described in the case where the harness H is pulled in the direction in which it is removed from the board case 20. First, a case where the removal preventing member 61 is attached to the harness H will be described. 4 and 5, the distal end side cable connector 53 of the harness H is connected to the board side connector 26 of the main board 25, and the harness H extends from the connector insertion hole 41 to the outside of the board case 20. Assuming that

  First, as shown in FIGS. 4A and 5A, the first split member 62 and the second split member 72 are arranged on both upper and lower sides of the harness H extending outside the substrate case 20 as a center. The housing recesses 62d and 72d are opposed to each other, and the arm portions 62b and 72b are arranged in a state facing the connector insertion hole side. Then, the two are brought into close contact with each other. When both are joined, as shown in FIG. 5B and FIG. 6A, a harness insertion hole 77 is formed by the housing recesses 62 d and 72 d, and the harness H is inserted through the harness insertion hole 77. become. Further, the locking portion 65 is inserted from the opening 74 a above the engagement hole 74, and the locking projection 65 a is locked to the engagement hole 74. For this reason, the 1st division member 62 and the 2nd division member 72 are integrated, and the removal prevention member 61 is formed. In addition, since the harness insertion hole 77 is formed slightly larger than the harness H, the removal preventing member 61 can move on the harness H.

  When the removal preventing member 61 is attached to the harness H, the removal preventing member 61 is moved along the harness H and inserted into the harness insertion hole 41 as shown in FIGS. 4B and 5B. Let When the removal preventing member 61 is inserted into the harness insertion hole 41, as shown in FIGS. 4C and 5C, the pair of integrated arm portions 62b and 72b are elastically deformed inward. It passes through the connector insertion hole 41 and expands outward to return to its original position. Further, the tips of the pair of projecting portions 62 c and 72 c integrated with each other come into contact with the outside of the wall portion 20 a of the substrate case 20 to stop the movement of the removal preventing member 61. As a result, the wall portion 20a of the substrate case 20 is sandwiched between the extended ends of the arm portions 62b and 72b and the protruding portions 62c and 72c, and the removal preventing member 61 is attached to the substrate case 20. It becomes a state. A slight gap 79 is formed between the distal end side cable connector 53 and the distal end of the removal preventing member 61.

  Next, the case where the harness H extending from the substrate case 20 is pulled in the direction in which the removal preventing member 61 is attached to the substrate case 20 will be described. When the harness H shown in FIG. 4C is pulled in the direction in which the harness H is pulled out (arrow B direction), the leading end side cable connector 53 moves in the direction of being pulled out from the board side connector 26 via the harness H, and the pulling out preventing member It contacts in a state where the tip of 61 is pressed. When the removal preventing member 61 is pressed by the distal end side cable connector 53, the distal ends of the integrated arm portions 62b and 72b come into contact with the inside of the wall portion 20a of the substrate case 20, and the removal preventing member 61 is inserted into the connector. Do not escape through the hole 41. As a result, the movement in the direction in which the distal end side cable connector 53 is pulled out is restricted, and the situation where the harness H is pulled out from the board case 20 can be prevented. Since the arm portions 62b and 72b can be elastically deformed, when the harness H is pulled with a stronger force, the arm portions 62b and 72b are bent so that the distal ends thereof are on the distal end side of the removal preventing member 61. Since the bent arm portions 62b and 72b restrict the movement of the removal preventing member 61, the removal preventing member 61 does not come out through the connector insertion hole 41, and the harness H is also pulled out from the board case 20. There is no.

  In this way, even if the harness H extending outward from the board case 20 is pulled in the direction to be pulled out, the harness H is not pulled out from the board case 20, so that the harness H connected to the main board 25 is remodeled with the harness (see FIG. It is possible to prevent fraudulent acts to be exchanged.

  Note that when the harness H is pulled in the direction in which the harness H is pulled out, the amount of movement that moves in the direction in which the distal end side cable connector 53 is pulled out is small. This is because the size of the gap 79 formed between the distal end of the removal prevention member 61 and the rear end of the distal end side cable connector 53 is small in a state where the removal prevention member 61 is mounted on the board case 20. As a result, even if the harness H is pulled in the direction to be removed, the distal end side cable connector 53 does not come out of the board side connector 26, and the harness H and the main board 25 are maintained in an electrically connected state. be able to.

  Moreover, although the arm parts 62b and 72b of the removal prevention member 61 in the above-described embodiment have been shown to protrude outward and rearward, the present invention is not limited to this, and as shown in FIG. 72b may be triangular, and as shown in FIG. 7 (b), the arm portions 62b and 72b are manufactured separately from the main body portions 62a and 72a and are attached to the main body portions 62a and 72a. May be. In these cases, both the triangular shape and the separately manufactured arm portions 62b and 72b are elastically deformable.

  Moreover, although the protrusion part 72c of the 2nd division member 72 shown to Fig.6 (a) in embodiment mentioned above showed the example which had the recessed part 73 provided with the opening part 73a below, it is not restricted to this, As shown in FIG. 6B, the opening 73 a may be covered with a closing plate 81 so that the engagement hole 74 cannot be seen from the outside of the removal preventing member 61. With this configuration, it becomes difficult to release the locking state of the locking portion 65 locked to the engagement hole 74 from the outside of the integrated first divided member 62 and second divided member 72. The division of the integrated first divided member and second divided member can be prevented. The closing plate 81 is not limited to a member separate from the second divided member 72, and may be formed integrally with the second divided member 72.

  Further, the removal preventing member 61 in the above-described embodiment can be shaped as shown in FIGS. That is, the removal preventing member 83 is composed only of the main body portions 62a and 72a having the protruding portions 62c and 72c of the removal preventing member 61 shown in FIG. The arm portions 62b and 72b attached to the are omitted. However, the removal preventing member 83 cannot be attached to the harness H extending from the board case 20 and moved into the board case 20 through the connector insertion hole 41, and the board case 20 is attached to the main board 25. 4 (c) described above in that the harness H is passed through the connector insertion hole 41 and the distal end side cable connector 53 is connected to the board side connector 26 before being attached to the harness H in the board case 20. This is different from the removal prevention member 61 shown in FIG.

  8 and FIG. 9 includes a first split member 84 made up of a protrusion 62c and a main body 62a having the protrusion 62c of the removal prevention member 61 shown in FIG. The projecting portion 72 c of the member 61, the second divided member 85 including the main body portion 72 a having the protruding portion 72 c, and the joint holding portion 75 are included. However, the distance L1 between the front end and the rear end of the removal preventing member 83 is slightly smaller than the distance L2 between the rear end of the front end side cable connector 53 and the inside of the wall portion 20a of the board case 20. Is formed.

  The pull-out prevention member 83 configured in this manner is in a state in which the harness H is passed through the connector insertion hole 41 and the distal end side cable connector 53 is connected to the board side connector 26 before the board case 20 is attached to the main board 25. The first divided member 84 and the second divided member 85 in a divided state are attached to the harness H in the substrate case 20 with the center thereof as a center. Then, the substrate case 20 is attached to the main substrate 25. When the harness H extending from the connector insertion hole 41 is pulled in this state, the rear end of the distal end side cable connector 53 comes into contact with the removal preventing member 83 and the rear end of the removal preventing member 83 is the board case 20. The contact in the inner side of the wall portion 20a is restricted, and the movement in the direction in which the distal end side cable connector 53 is removed is restricted. As a result, it is possible to prevent the harness H from being removed from the board case 20, and to prevent an illegal act of replacing the harness H connected to the main board 25 with a modified harness (not shown). .
