Description

  The present invention relates to an electric connection box electric wire holding structure that prevents the electric wire from coming out of a wiring board in an electric connection box mounted on a vehicle or the like in the radial direction at the same time as an under cover is assembled.

  6-8 shows each form of the electric wire holding structure of the conventional electrical junction box (refer patent document 1).

  In this structure, as shown in FIG. 6, the wiring board 71 made of an insulating resin housed in an electrical junction box mounted on an automobile is provided with a wiring groove (housing groove) 72 in the XY direction, The wiring 73 is wired (wired) in a desired shape in a single stroke from the nozzle of a wiring head (not shown), and the wiring groove is disposed at a required position in the longitudinal direction of the wiring groove 72 as shown in FIG. A pair of protrusions 74 perpendicular to the inner surfaces on both sides of 72 are provided to face each other, and when the electric wires 73 are wired, the electric wires 73 are press-fitted between the pair of protrusions 74 to be held without coming out in the radial direction.

  FIG. 8 shows an upper end portion of the inner surface on both sides of the wiring groove 72 after the electric wire 73 is wired in the wiring groove 72 at a required position in the longitudinal direction of the wiring groove 72 of the wiring board 71 similar to FIG. Is crushed from above with a pressing jig 75 and protruded inward in a protruding shape (the protrusion is indicated by reference numeral 76) to prevent the wire 73 from coming out of the wiring groove 72 in the radial direction.

Japanese Patent Laid-Open No. 2000-115957 (FIGS. 2, 3, and 7)

  However, in the conventional structure shown in FIG. 7, when the press-fitting allowance of the electric wire 73 fluctuates due to the gap size between the pair of protrusions 74 and the outer diameter of the electric wire 73 and the press-fitting allowance is large, the electric wire If the wire 73 is damaged or the press-fitting allowance is small, there is a concern that the wire 73 may come out in the radial direction due to vibrations of the vehicle, etc. There was concern that it could be.

  Further, in the structure of FIG. 8, after the electric wires 73 are laid out on the wiring board 71, the number of manufacturing steps of the electrical junction box is increased or the wiring grooves 72 are formed by the press jig 75 in order to form the protrusions 76. There was a concern that the equipment cost would increase by performing a hot press or the like in order to crush the upper edge well.

  An object of the present invention is to provide an electric connection box electric wire holding structure capable of reliably preventing the electric wires from coming out of the electric wire receiving grooves in the radial direction without taking time and cost. And

To achieve the above object, an electric junction box electric wire holding structure according to claim 1 of the present invention is an electric junction box comprising a wiring board having a plurality of electric wire receiving grooves and a cover joined to the wiring board. A rib is provided on the cover to block any of the wire receiving grooves and prevent the electric wires from protruding in the radial direction from the wire receiving grooves , and a connector housing and a space adjacent to the connector housing in the cover. The rib is provided in the space, and the bottom wall of the connector housing closes the wire receiving groove other than any one of the wire receiving grooves .

With the configuration described above, the wiring board is assembled to the cover, and at the same time, the ribs of the cover block (cover) the electric wire receiving groove of the wiring board, thereby preventing the electric wires in the electric wire receiving groove from coming out in the radial direction. Even if the electric wire in the electric wire receiving groove tries to come out from the electric wire receiving groove in the radial direction, it comes into contact with the rib and is prevented from coming out. Ribs increase the rigidity of the cover.
Further, the ribs connect the connector housing and the cover main body, connect the connector housings to each other, or connect the wall portions of the cover main body to each other to increase the strength (rigidity) of the cover. The rib plays both the role of increasing rigidity and preventing the wire from coming out.
In addition, the bottom wall surface of the connector housing having a width wider than the tip end surface of the rib covers the opening of the electric wire receiving groove, so that even if the electric wire is about to come out from the electric wire receiving groove in the radial direction, the electric wire contacts the bottom wall surface, Escape is surely prevented.

  The electric wire holding structure for an electric junction box according to claim 2 is characterized in that, in the electric wire holding structure for an electric junction box according to claim 1, the rib covers the electric wire receiving groove over the entire length.

  With the configuration described above, the rib is close to or in contact with the opening of the electric wire receiving groove and the opening is closed in the longitudinal direction, so that the electric wire is prevented from being pulled out in the radial direction and partially lifted up.

  The electric wire holding structure for an electric junction box according to claim 3 is the electric wire holding structure for an electric junction box according to claim 1, wherein one or a plurality of the ribs block the electric wire receiving groove in the transverse direction.

  With the above configuration, even if the rib intersects the electric wire receiving groove and the electric wire tries to come out from the electric wire receiving groove in the radial direction, the electric wire partially abuts on the rib and the electric wire is prevented from coming out.

The electric junction box electric wire holding structure according to claim 4 is the electric junction box electric wire holding structure according to any one of claims 1 to 3 , wherein the electric wire receiving groove communicates with the press contact terminal insertion hole of the wiring board. It is characterized by including an electric wire accommodation groove.

  With the above configuration, the electric wire in the pressure receiving electric wire receiving groove is blocked by the rib or the bottom wall of the connector housing, and the radial pull-out is reliably prevented.

According to the first aspect of the present invention, by assembling the wiring board to the cover, the ribs of the cover block the electric wire receiving grooves of the wiring board, and it is possible to easily and reliably prevent the electric wires from coming out in the radial direction. Since it is not necessary to form protrusions and protrusions in the narrow wire receiving groove as in the conventional case, the resin molding (manufacturing) cost of the wiring board can be reduced. In addition, even if the electric wire is about to come out, it comes into contact with the rib and is surely prevented from coming off, so the concern that the electric wire will come out in the radial direction along conventional protrusions and protrusions due to strong vibration or the like is eliminated. Also, the ribs increase the rigidity of the cover and increase the mechanical strength of the electrical junction box.
Moreover, since the rib for increasing the rigidity of the cover is also used for preventing the wire from coming out, a separate member for preventing the wire from coming out becomes unnecessary, and the cost of the cover and the entire electrical junction box can be reduced. Further, by using the bottom wall of the connector housing wider than the rib, it is possible to easily and reliably prevent the wire from coming out from the wire housing groove in the radial direction.

  According to the second aspect of the present invention, since the rib covers the wire receiving groove over the entire length with the rib, it is possible to reliably prevent the wire from coming out in the radial direction and partially rising.

  According to the invention described in claim 3, even when the electric wire is about to come out from the electric wire receiving groove in the radial direction, it is possible to prevent the electric wire from coming out by partially contacting the rib.

According to the fourth aspect of the present invention, the wire in the pressure receiving wire receiving groove is closed with the rib or the bottom wall of the connector housing, and the radial disconnection is surely prevented, thereby improving the pressure contact reliability. it can.
