2. Description of the Related Art FIG. 5 shows a general automobile harness 1, and FIG. 6 shows a wiring state. In a lighting harness of an automobile, one electric wire needs to be branched as shown in FIG. 6 because of turning on and off a plurality of lamps at the same time. FIG. 7 shows a state where a general branch is performed. At the same time, the middle part of the electric wire 2 serving as a trunk line is peeled, and the end of the electric wire 3 serving as a branch line is peeled, and the respective conductor portions are caulked with a metal fitting 4 and connected. Since a metal portion such as a conductive wire is exposed at the branch portion, when a plurality of wires are branched to one connector, the positions are slightly shifted. After the branch wiring is formed, the wiring is covered with a tape or the like for insulation. In addition, connectors (not shown) are connected to the ends of the electric wires 3 to be branched.

[0003]

In the above-mentioned conventional harness, when the electric wire is branched, it takes much time and labor such as peeling and crimping of metal fittings, and displacing the respective positions at the time of peeling. However, there is a problem that it takes time to connect a connector to a branch destination. By the way, as a method of branching an electric wire, there is also known a method of pressing a metal fitting provided with a press-contact slot to the electric wire. However, even if the electric wire is branched by press contact, there is a problem that the trouble of crimping the connector terminal to the branched electric wire cannot be omitted.
On the other hand, in computer equipment, when connecting a plurality of boards or the like in parallel to a common bus, a connector may be pressed against an intermediate portion of the wire, but in such a connection, the connector is connected to a main wire. Since the branching wire is at a right angle, the branch wire protrudes when applied to an automobile harness. Since a harness for an automobile generally has to be arranged in a narrow place, there is a problem that it cannot be used in a space. In addition, there is also a problem that the branch line is unstable due to wobbling, and comes into contact with the vehicle body due to vibration to generate abnormal noise.

The present invention has been made in view of the above problems, and has as its object to provide a press-connecting connector capable of efficiently producing a harness requiring branch wiring and stabilizing the state of the branch line. I do.

[0005]

According to a first aspect of the present invention, there is provided a fitting which can be connected to a mating terminal at one end and a wire can be pressed at the other end. In a press-fitting connector in which terminals provided with press-fittings are respectively incorporated in a connector case, an end portion on the side where the press-fittings are provided has a regulating cover for restricting a direction in which an electric wire pressed against the press-fittings is taken out. Is mounted. According to a second aspect of the present invention, in the first aspect, the regulating cover is attached to the connector case so as to cover the press fitting, and the cover is interlocked with a mounting operation of the connector case. It is characterized in that the direction in which the electric wire is taken out can be regulated. According to a third aspect of the present invention, in the first or second aspect, the restricting cover is fitted to the connector case so as to cover the press fitting, and a restricting wall is formed on a side surface thereof. When the restricting cover is fitted to the connector case, the restricting wall and the restricting direction of the electric wire are regulated while the electric wire is sandwiched between the restricting wall and a wall surface facing the restricting wall and the connector case. It is characterized by having.

[0006]

According to the first aspect of the present invention, when the electric wire is pressed against the press fitting, the electric wire is arranged in parallel with the surface on which the press fitting is provided. Taken out in the direction. According to the second aspect, when the restricting cover is attached to the connector case, at the same time, the direction in which the electric wire is taken out is restricted. According to the third aspect, when the regulating cover is attached, the electric wire is sandwiched and held between the regulating wall and the opposing wall surface on the connector case side, so that the regulated state of the electric wire is stable. Become.

[0007]

According to the first aspect of the present invention, branch wiring can be easily performed, and the branch line can be corrected in a desired direction. Further, according to the invention of claim 2, since the regulating operation of the electric wire can be performed simultaneously with the attaching operation of the regulating cover, the workability is excellent. According to the third aspect of the present invention, since the electric wire is sandwiched between the regulating wall and the opposing wall surface on the connector case side, the electric wire is held in a stable state without being separated.

And the terminal holding portion 12 at an intermediate portion.
Is held in. That is, the terminal 20 is held by the connector case 10 in a state where the press contact portion 21 protrudes from the end of the connector case 10 on the terminal holding portion 12 side, and the fitting terminal protrudes into the hood portion 11. Note that the connector case 10 holds a plurality of terminals 20, and the press contact portions 21 are arranged in a staggered manner at the end of the connector case 10 on the terminal holding portion 12 side.

The cover 30 covers an end of the connector case 10 on the terminal holding portion 12 side, and extends vertically from a base wall 31 facing the end, and both ends in the longitudinal direction of the base wall 31. Engagement walls 32a, 32b,
A regulating wall 33 extends vertically from one longitudinal side of the base wall 31 and connects the engaging walls 32a and 32b. Here, a pair of engagement projections 13 are formed on the side surface of the terminal holding portion 12 in the connector case 10, and engagement holes 34 are formed in the engagement walls 32 a and 32 b in accordance with the engagement projections 13. I have. Further, a clamp 35 is formed on the regulating wall 33 so as to protrude.

b denotes an engagement projection 1 formed on a side surface of the connector case 10.
Contact 3

The cover 30 on the engaging projection 13
The insertion side wall surface is an inclined surface, and when the cover 30 is pushed in, the engaging walls 32a and 32b ride on the inclined surface and are pushed outward. Then, when the press contact portion 21 of the terminal 20 approaches the back surface of the base wall 31, the engaging projection 13 enters into the engaging hole 34 formed in the engaging wall 32a, 32b, and the cover 30 and the connector case 10 Are fitted with the concave and convex. FIG. 2 shows a state in which two press-connecting connectors 40 are arranged in the middle of a plurality of covered electric wires W. As shown in the figure, the insulated wire W is sandwiched between the cover 30 and the connector case 10 on the side of the terminal holding portion 12 in the connector case 10 and the removal direction thereof is regulated. That is, the insulated wire W is
Along the side of the hood portion 11, and as a result, it is parallel to the fitting direction.

The harness 50 can be fixed to a vehicle body by a clamp 35. Then, the fitting direction of the connector case 10 becomes parallel to the mounting surface, and even if a branch line is mounted, the branch line does not protrude from the mounting surface. Therefore, the branch line can be easily wired even in a narrow place. In the embodiment described above, only one of the directions of taking out the covered electric wire is regulated, but both directions may be regulated. Further, the regulating direction does not necessarily have to be parallel to the fitting direction. When it is desired to draw the branch line in a 45-degree direction, the electric wire may be regulated so that the electric wire can be taken out in the 45-degree direction.
