[Problems to be solved by the device]

 In view of the above points, the present invention has an object to provide a structure capable of easily connecting a connector on the electrical component side and a connector on the harness side via a panel.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a connector connection structure for connecting a connector of an electrical component mounted on a panel surface and a harness connector on the rear surface side of the panel through a panel hole, wherein the connector for the harness is a rear surface of the panel. The bracket is fixed to the bracket side by a spring so that it can move freely, and the bracket is fixed to the back side of the panel by the clip, and at the same time when the electrical component of the connector integrated type is attached. It is characterized by being connected with a connector.

[0006]

[Action]

 When connecting the connectors, first attach the harness connector to the back side of the panel. That is, the bracket portion is fixed to the back side of the panel by the clip portion. The harness connector can be moved vertically and horizontally by a spring portion. Next, the electrical components are attached to the panel surface. Simultaneously with the mounting of the electrical component, a connector integrated with the electrical component is coupled to the harness connector. Here, the spring part of the harness connector absorbs the mounting dimension error of the electrical component and enables a smooth connection.

【Example】

 FIG. 1 is an exploded perspective view showing an embodiment of a connector connecting structure according to the present invention, and FIG. 2 is a longitudinal sectional view of an essential part showing the connected state. In this structure, a movable connector 2 for a harness is assembled on the back side of the panel 1, and a connector-integrated electrical component 3 is mounted on the front side of the panel 1 to automatically connect both connectors 2, 4. is there.

The harness connector 2 includes a connector body 7 that houses a plurality of female terminals 6 connected to the wire harness 5, and a spring piece 8 that surrounds the rear portion of the connector body 7 and projects in four directions. It is composed of a flange bracket 9 that supports the connector body 7 so that it can move vertically and horizontally.

A pair of semi-cylindrical insertion guides 11, 11 each having a tip 11a tapered and protruding are integrally provided on both side walls 10 of the housing in the front half of the connector body 7. Further, a stop projection 13 for the spring piece 8 of the bracket 9 is provided on the peripheral wall 12 at the substantially central portion of the connector body 7, and a contact flange 14 for the bracket 9 is provided at the rear end portion of the connector body 7. (Fig. 2) is provided so as to project.

The bracket 9 is formed of a synthetic resin into a substantially flat plate shape, and the connector body 7 is inserted and held in a rectangular opening 16 formed in the center of the flat plate portion 15. At the front edge of the opening 16 are provided spring pieces 8 projecting diagonally inward vertically and horizontally. A housing groove 17 (FIG. 2) for the contact flange 14 is provided at the rear edge of the opening 16.

The tip of the spring piece 8 is brought into contact with the stop projection 13 of the connector body 7, and the bottom surface of the housing groove 17 of the bracket 9 is brought into contact with the rear flange 14 of the connector body 7, thereby The body 7 is elastically held. Further, a pair of clamps 18, 18 are provided on the upper and lower ends of the bracket 9 so as to project forward. The clamp 18 engages with a round hole 20 of a stay 19 provided on the back side of the panel 1 to fix the bracket 9.

The stay 19 is fixed to a groove-shaped portion 21 protruding from the back surface 1b of the panel 1, has a rectangular insertion hole 22 for the connector body 7 in the center, and has the round holes 20 in the top and bottom. is doing. The groove-shaped portion 21 has a circular insertion hole 23 for the connector body 7. The panel 1 has a mounting hole 24 for the electrical component 3 and an insertion hole 25 for the connector 4 of the electrical component 3.

The electrical component 3 integrally has a connector 4 on the back side and is fixed to the panel surface 1 a with bolts 32. The connector 4 is inserted through the panel hole 25, and the ring-shaped packing 26 at the tip is brought into contact with the surface 21a of the groove-shaped portion 21 to be hermetically sealed.

That is, the connector 4 has a male tab terminal 28 in a fitting portion 27 for the connector body 7 of the harness connector 2, and an annular portion continuous with the outer periphery of the tip of the fitting portion 27. 29 has a packing fitting groove 30, and the packing 26 fitted in the fitting groove 30 can be brought into contact with the outer peripheral edge 21 a of the circular hole 23 of the panel groove type portion 21. The fitting portion 27 has a pair of engaging grooves 31 and 31 for the insertion guides 11 and 11 of the connector body 7.

The electrical component 3 is mounted after the harness connector 2 is assembled on the back side of the panel 1. That is, as shown in FIG. 2, by fixing the bracket 9 of the harness connector 2 to the stay 19 by the clamp 18, the front half of the connector main body 7 is directed from the insertion hole 23 of the groove-shaped portion 21 toward the panel 1 side. Project. As described above, the connector body 7 is held by the spring pieces 8 in a loose fit in the vertical and horizontal directions.

At the same time when the electrical component 3 is joined to the panel surface 1 a, the integrated connector 4 is fitted into the front half of the connector body 7 through the panel hole 25. Here, the connector body 7 absorbs a mounting dimension error of the electrical component 3 by the spring piece 8 and enables a smooth connector coupling. Further, the tip packing 26 of the electrical component side connector 4 contacts the surface 21a of the panel groove 21 to prevent water and the like from entering the connectors 4 and 2.
