Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pressure contact connector, and more particularly to a pressure contact connector suitable for use in an automobile harness or the like.

[0002]

[Prior art]

 FIG. 5 shows a general automobile harness 1, and FIG. 6 shows a wiring situation. In a vehicle lighting harness, it is necessary to branch one electric wire as shown in FIG. 6 in order to turn on and off a plurality of lamps at the same time. FIG. 7 shows a state where general branching is performed. While peeling off the middle part of the electric wire 2 which becomes the trunk line, the end part of the electric wire 3 which becomes the branch line is peeled off, and each conducting wire portion is caulked with the metal fitting 4 to be connected. Since metal parts such as conductors are exposed at the branch part, when branching multiple wires into one connector, the positions are slightly shifted. After the branch wiring is formed, it is covered with tape or the like for insulation. In addition, connectors (not shown) are connected to the ends of the electric wires 3 that branch.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional harness, there is a great deal of work such as stripping and crimping metal fittings when branching the wire, and shifting each position when stripping the wire, and also the labor of connecting the connector to the branch destination. There was a problem that By the way, as a method of branching an electric wire, a method of press-fitting a metal fitting having a press-connecting slot to the electric wire is also known. However, there is a problem that even if the wire is branched by crimping, the labor of crimping the connector terminal to the branched wire cannot be omitted. On the other hand, in computer equipment, when connecting multiple boards in parallel to a common bus, a connector may be pressed into the middle of the wire. Since it is at a right angle to the branching wire, the branching wire will protrude when applied to a harness for automobiles. Since the harness for automobiles generally has to be installed in a narrow space, there is a problem that it cannot be used in space. In addition, the branch line is staggered and unstable, and there is a problem that vibration causes the vehicle to come into contact with the vehicle body and generate abnormal noise.

The present invention has been made in view of the above problems, and an object thereof is to provide a press-connecting connector that can efficiently produce a harness that requires branch wiring and that can stabilize the state of the branch line. To do.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the invention according to claim 1 is a press-connecting connector having a fitting opening having a fitting fitting at one end and a fitting fitting electrically connected to the fitting fitting at the other end. A regulation cover is provided which is connected to the end portion where the above-mentioned pressure contact fitting is disposed and regulates the take-out direction of an electric wire which is pressure-contacted to the pressure contact fitting.

[0006]

[Action]

 In the invention according to claim 1 configured as described above, when the electric wire is pressed against the crimping metal fitting, the electric wire is aligned parallel to the surface where the crimping metal fitting is arranged, and is perpendicular to the fitting direction. However, if the regulation cover is made to cover the end portion where the press-fitting metal fitting is provided, the electric wire take-out direction is regulated in the desired direction by the regulation cover. Therefore, if the branch line is regulated toward the required part, the branch line will not become unstable. Further, if the electric wire is regulated so as to be parallel to the fitting direction, the branch line and the electric wire become parallel, and the protruding portion is reduced.

[0007]

[Effect of device]

 As described above, according to the present invention, the branch wiring can be easily performed and the branch line can be taken out in a desired direction, so that the branch line can be prevented from becoming unstable, and the branch line can be used as a main line if necessary. It is possible to provide a pressure contact connector that can be prevented from protruding from the pressure contact connector.
