The height dimension L2 up to the rear end face of the wire drawing side is set to be substantially equal to the height dimension L2.

In such a connector fitting detection structure, the male connectors 33 are fitted into the fitting hood 31, respectively, and then the detection plates 37a, 37b, 37c are inserted between the fitting hoods 31, respectively. Then, the wall member 41 is inserted under the connection box main body 29. At this time, the fitting hood 3
When the male connector 33 is only partially inserted into the connector 1, the distal ends of the detection plates 37 a, 37 b, and 37 c abut against the side wall of the male connector 33, so that the male connector 33 is incompletely fitted. When the state can be detected and the detection jig 35 can be attached to the electric connection box, it can be detected that the male connector 33 is completely fitted to the fitting hood 31.

When detecting the height of the male connector 33, the upper surface of the male connector 33 and the detection plate portions 37a, 37
If there is a gap between b and 37c, the fitting state of the connector cannot be accurately detected, so the distance between two points is checked. Therefore, in the detection jig 35, the wall member 41 is provided to detect the height of the male connector 33 from the lower surface 29a of the connection box main body 29.

[0007]

However, in the above-described conventional connector fitting detection structure, the fitting hood portion 31 is not provided.
After the male connector 33 is fitted to the connector, the detection jig 35 may be forgotten to be inserted between the fitting hoods 31 and to forget to detect the fitted state, that is, a so-called forgetting to confirm may occur.

In the above-described fitting detection structure, the detection jig 3
After the fitting 5 is inserted between the fitting hoods 31 to detect the fitting, the detection jig 35 must be pulled out from the fitting hood 31 this time, which is troublesome and poor in workability.

Further, in the fitting detection structure, the wall member 4
1 is in contact with the lower surface 29a of the connection box body 29 to detect the height of the rear end of the male connector 33 fitted to the fitting hood portion 31, so that the size of the detection jig 35 is increased. .

Therefore, the present invention can improve the operability without forgetting to check the fitting state,
It is an object of the present invention to provide a connector fitting detection structure of an electric connection box that can reduce the size of a detection jig.

1a, 51b, 51c and the extraction plate portions 51a, 51
b, 51c, detectors 53a, 53b provided on one side,
53c and a connecting plate portion 55 connecting the other sides of the extraction plate portions 51a, 51b, 51c.

The extraction plate portions 51a, 51b, 51c are in the shape of a long plate, and are previously arranged on the outer periphery of the connection box body 43 between the fitting hood portions 45a, 45b, 45c. Further, a guide convex portion 57 (see FIG. 3) is formed on one surface side of the extraction plate portion 51. The guide convex portion 57 is slidably fitted to a guide concave portion 59 formed on the side wall of the fitting hood portions 45a, 45b, 45c, and the guide convex portion 57 and the guide concave portion 59 constitute guide means. . By this guide means, the extraction plate portions 51a, 51b, 51c move the fitting hood portions 45a, 45a along the direction intersecting the fitting direction.
The detection jig 49 is prevented from being lifted from between the fitting hood portions 45a, 45b, and 45c while being pulled out from between 5b and 45c.

The detecting portion 53 has an inverted L-shaped one end on one side of the extraction plate portion 51, and is provided with a contact portion 61. The surface of the contact portion 61 on the side of the connecting plate portion 55 is a contact surface 63. The sum of the height L3 from the upper surface of the guide convex portion 57 to the detection portion 53 and the distance L4 from the bottom of the extraction plate portion 51 to the upper surface of the guide convex portion 57 is fitted to the fitting hood portion 45. The height L5 of the male connector 47 is set substantially equal to the height L5. The detection unit 53 allows the extraction plate 51 to be pulled out from between the fitting hoods 45 in a state where the connector 47 is completely fitted to the fitting hood 45, and the connector 47 is connected to the fitting hood 45. In the incompletely fitted state, the contact surface 63 abuts against the side wall of the connector 47 and regulates the removal of the removal plate portion 51 from between the fitting hood portions 45.

The above-mentioned completely fitted state is a state in which the male connector 47 is completely inserted into the fitting hood 45, and the incompletely fitted state is a state in the middle of the fitting hood 45. The state in which the male connector 47 is inserted only up to this point.

Next, a procedure for detecting the fitted state of the connector by the above described fitting detection structure will be described. First, the detection jig 49 is mounted on the fitting hood portion 45 in advance. In this case, the extraction plate portion 51 is inserted and arranged between the fitting hood portions 45, and the detection portion 53 is arranged around the fitting hood portion 45 on the opposite side to the connection plate portion 51.

Next, the male connector 4 is
7 are fitted respectively. After the male connector 47 is fitted to the fitting hood 45, the extraction plate 51 of the detection jig 49 is removed.
From the fitting hood portion 45. At this time, when the extraction plate portion 51 can be easily extracted from between the fitting hood portions 45, it is understood that the male connector 47 is completely fitted into the fitting hood portion 45. If the contact surface 63 of the detection portion 53 contacts the side wall of the male connector 47 and the extraction plate portion 51 cannot be easily extracted from between the fitting hood portions 45, the male connector is not fitted. It can be seen that it is in an incompletely fitted state where it is not completely inserted into the mating hood portion 45. In this case, the extraction plate portion 51 is

Even if the detection is forgotten, the detection jig 49 remains attached to the fitting hood portions 45a, 45b, 45c, so that it can be seen that the detection jig 49 has a missed detection due to the rattling sound of the detection jig 49.

Further, since the fitting detection work can be performed only by pulling out the detection jig 49, the workability of the fitting detection work is improved. Further, since the detection jig 49 is pulled out from the periphery of the fitting hood portion 45 after the detection operation, the structure around the fitting hood portion 45 is simplified, and the detection jig rattles, falls off, and the like. Can be prevented from being caused by providing the detection jig 49 around the fitting hood portion 45.

Further, the fitting hood portions 45a, 45b, 4
By fitting the guide projection 57 into the guide recess 59 on the side wall 5c, the lifting of the detection jig 49 is prevented, so that there is no need to provide a wall member that comes into contact with the lower surface 29a of the connection box main body 29 as in the related art. Alternatively, the size of the detection jig 49 can be reduced.

Next, another shape of the detecting section 53 will be described. As shown in FIG. 4, on the contact surface 63 of the detection unit 53,

As described above, according to the first aspect of the present invention, the fitting detection operation can be performed by pulling out the detection jig from between the fitting hood portions, so that forgetting to confirm is surely prevented. And workability can be improved. Further, by providing the guide means between the fitting hood portion and the detection jig, the size of the detection jig can be reduced. Furthermore, since the detection jig is pulled out from the periphery of the fitting hood after the detection operation, the structure around the fitting hood is simplified, and the detection jig such as rattling or falling off of the detection jig is reduced. It is possible to prevent the occurrence of a problem caused by providing the tool around the fitting hood portion. In addition, since the detection jig can be reused, the cost of the fitting detection operation can be reduced by effectively using one detection jig.

According to the second aspect of the present invention, by inserting the extraction plate portion between the fitting hood portions in advance, after the connector is fitted to the fitting hood portion, the extraction plate portion is connected to the fitting hood portion. If it is pulled out from the space, the fitting state can be detected, so that forgetting of the detection can be reliably prevented, and the workability of the fitting detection can be improved. Further, by providing the guide means between the fitting hood portion and the detection jig, the size of the detection jig can be reduced.

According to the third aspect of the present invention, even if the connector is fitted in the fitting hood in an incomplete state, if the detection jig is pulled out from between the fitting hoods, the inclined surface becomes the corner of the connector. The connector can be slid and pressed in the fitting direction to bring the connector into a completely fitted state.
