Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bolted connector that fastens a pair of connectors with bolts, and is preferably used for a wire harness for automobiles and the like.

[0002]

[Prior Art]

 Conventionally, bolted connectors have been used when connecting large-sized connectors that require a strong fastening force, or when connecting a battery power supply to an electrical junction box that requires reliable electrical connection.

As shown schematically in FIG. 4, a bolt tightening connector is a male connector 2 inserted into a fitting hole 1a of a female connector 1 and a bolt 3 is inserted from an inserting direction by using an impact wrench. Through the bolt hole 2a of the connector 2, it is fastened to the bolt hole 1b provided in the female connector 1.

[0004]

[Problems to be solved by the device]

 The bolt tightening connector having the above-mentioned configuration has no problem when there is a space in the bolt tightening direction, but as shown in FIG. 5, when the connector installation part is surrounded by the wall W and there is no space in the bolt tightening direction, The bolt cannot be tightened with an impact wrench.

In order to solve the above problem, if a special type of impact wrench with a bent tip bent at right angles is used, tightening is possible even when there is no space in the tightening direction. However, in that case, there is a drawback that a special type of impact trench must be prepared at the connector installation site.

The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to perform a tightening operation using a normal impact wrench even in a place where there is no tightening space for the connector. It is a thing.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention relates to a first connector and a second connector, which are fitted to each other, which are coupled by bolting, in which a fitting hole for inserting a second connector provided in the first connector is provided. While the bolt hole is formed in the side wall portion, the second connector is provided with a concave portion having an inclined surface on the wall surface facing the bolt hole so that the second connector moves in the inserting direction in response to tightening of the bolt. In other words, the present invention provides a bolt tightening connector configured to connect the connectors in a direction orthogonal to the bolt tightening direction.

It is preferable that a taper corresponding to the inclination angle of the inclined surface is provided on the outer peripheral portion of the tip that abuts the inclined surface of the bolt.

[0009]

[Action]

 As described above, when the bolt is tightened from the side wall of the first connector to the inclined surface of the second connector, the tightening force of the bolt is converted to the direction perpendicular to the inclined surface, and the second connector tightens the bolt. It is tightened in the direction orthogonal to the direction and can be firmly connected to the first connector.

[0010]

【Example】

 The present invention will be described below with reference to the embodiments shown in the drawings. In FIGS. 1 and 2, 10 is a male connector that constitutes the first connector, 11 is a female connector that constitutes the second connector, and each has a multi-pole terminal accommodating chamber inside the connector housing. In the male connector 10, a box-shaped side wall portion (hood) 10b is projected from one end side of the terminal accommodating chamber forming portion 10a, and an opening surrounded by the side wall portion 10b is used as a female connector fitting hole 10c.

A bolt hole 13 for inserting the bolt 12 is formed in a part of the side wall portion 10b surrounding the female connector fitting hole 10c.

The female connector 11 is provided with a recess 15 having an inclined surface 15a on a wall surface 11a facing the bolt hole 13 when inserted into the fitting hole 10c. The concave portion 15 is cut out from the end edge 11b of the wall surface 11a, and is provided with the inclined surface 15a inclined rearward from the front end P1 of the cut edge at a required angle. From the rear end P2 of the inclined surface 15a, a linear stopper surface 15b is formed parallel to the connector insertion direction.

Due to the above structure, when the bolt 12 is tightened from the bolt hole 13 of the side wall portion 10b of the male connector 10 with the female connector 11 inserted in the fitting hole 10c of the male connector 10, the bolt 12 The tip is inserted into the concave portion 15 of the female connector 11, and the tip edge thereof abuts the inclined surface 15a.

As the bolt 12 is tightened, the inclined surface 15a is moved forward on the insertion side. When the female connector 11 is pushed to a predetermined position inside the fitting hole 10c, the tip end surface 12a of the bolt 12 contacts the stopper surface 15b, and the tightening of the bolt 12 is stopped here.

Since the bolts are tightened as described above, the bolt can be tightened using a normal impact wrench. Therefore, even when there is no space in the insertion direction of the connector, it is possible to connect the bolted connector with a normal impact wrench.

The bolt 12 is made of resin so that the inclined surface of the connector will not be damaged by contact with the bolt. If an inclined surface 12b having an angle corresponding to the inclined surface 15a is formed on the outer peripheral surface of the tip of the bolt 12 as shown in FIG. 3, the inclined surface 12b of the bolt contacts the inclined surface 15a of the recess 15. Therefore, it is preferable.

[0017]

[Effect of the device]

 As is clear from the above description, in the bolted connector according to the present invention, the bolt hole is provided in the side wall of one connector, while the other connector is provided with the inclined surface at the position where the tip of the bolt abuts. , The connectors can be connected to each other by moving the connectors in the direction orthogonal to the tightening direction of the bolts. Therefore, when there is no space in the insertion direction of the connector, the bolt can be tightened from the direction orthogonal to the insertion direction using a normal impact wrench.
