2. Description of the Related Art Among a pair of male and female connectors in which a plurality of connectors are integrally connected and a plurality of connection terminals are fitted and inserted in a housing, a fitting bolt held by one connector is received by a receiving portion of the other connector. Regarding the connection of the multipolar connector in which both connectors are fitted by screwing on
As a conventional means for confirming completion of joining of both connectors, there is a structure as shown in FIGS. 10 and 11, for example.

In the structure shown in FIG. 10, the female connector 1 has a housing 1a having a large number of terminal accommodating chambers 4 each having 50 or more poles.
The housing 1a is provided with a bolt through hole 7 through which the tightening bolt 3 penetrates. The male connector 2 has the same number of terminal accommodating chambers 5 as the female connector 1, and a bolt fixing portion 6 is provided at the center of the housing 2a. When the female and male connectors 1 and 2 are fitted together, the male screw portion 3a of the tightening bolt 3 on the female connector 1 side is screwed into the female screw portion 6a of the bolt fixing portion 6 of the male connector 2 so that the female connector 1 and the male connector 1 are joined together. The connector 2 is fitted.

Next, in the structure shown in FIG. 11, the connection terminal of the wire harness is inserted through the through hole 42 of the connector 41 from below, the connector 41 is fitted into the connector guide 40, and the inner connector having the male connector is built in. A bolt 60 provided at the center of the case 30 is screwed into a nut 45 provided at the center of the connector 41. Then, when the bolt 60 is rotated, the connector 41 is raised and the bolt 60 of the inner case 30 is rotated.
The pin 71 comes into contact with the lower end of a pin 71 provided in the vicinity of which is vertically slidable, and the pin 71 is pushed upward as screwing proceeds. On the other hand, the connector 27 continuous with the busbar 27 of the inner case
The a is inserted into the through hole 42, and when screwing of the bolt 60 is completed, the a is joined to the connection terminal of the wire harness. When the joining is completed, the upper end surface of the pin 71 is flush with the upper surface of the inner case 30 that supports the bolt 60, so that it can be visually recognized from the outside that the joining is complete.

[0005]

However, as shown in FIG.
In the case of the connector mating structure shown in Fig. 4, it is the operator's judgment as to whether or not the mating of the male and female connectors is complete, and if there is a flaw on the threaded surface of the bolt or nut. Or, when fine dust is caught, the joining degree cannot be judged only by the torque. Further, when the pin shown in FIG. 11 is used as an indicator showing the degree of fitting, it is difficult to visually confirm the end face of the pin when the connector is located at a location where workability is poor during assembly or maintenance. There is a problem that the property is significantly impaired. The object of the present invention is made in view of such conventional problems,
It is an object of the present invention to provide a multi-pole connector fitting recognition structure capable of surely confirming the completion of fitting of the connector.

[0006]

The above object of the present invention is to hold a connector in one of a pair of male and female connectors in which a plurality of connectors are integrally connected and a large number of connection terminals are fitted and inserted in a connector housing. In a multi-pole connector fitting recognition structure in which male and female connectors are fitted by screwing the fitted fitting bolt into the receiving portion of the other connector, a cone is attached to the tip of the fitting bolt mounted in one connector. A ring groove is provided in contact with the conical portion and the conical portion, and two wire springs are provided horizontally on the other connector facing the receiving portion in parallel at intervals smaller than the diameter of the fitting bolt. Can be achieved by a multi-pole connector fitting recognition structure. Further, the above object is achieved by providing a sliding member to which an end portion of the wire spring is fixed and a striking piece that emits a striking sound is attached, and a stopper on the connector housing side so that the striking piece emits a striking sound. can do. Further, the above object can be achieved by the wire spring always urging the sliding member in the outward direction and the striking piece abutting on the stopper.

[0007]

When the fitting bolt provided on one connector for fitting the male and female connectors is screwed into the receiving portion of the other connector, it is laid across the front surface at a distance smaller than the bolt diameter. The conical portion of the bolt tip is pushed between the wire springs of the book. When the two wire springs are further screwed, the distance between the two wire springs can be gradually widened along the slope of the conical portion, so that the sliding members to which both ends of the wire springs are fixed move toward each other. Slide. Next, the conical portion rides over the two wire springs, and at the moment when the wire springs fall into the ring groove of the bolt, the two wire springs return to their original intervals, so that the sliding members that have been pulled toward each other are also line springs. Due to the restoring force of, it instantly returns to its original position. At this time, the striking piece attached to the sliding member impacts the stopper provided on the connector housing side to generate a striking sound. The completion of fitting of both connectors can be easily recognized by the impact sound.
