An electric wire on the opposite direction from the lateral leading-out direction among electric wires connected to the connector housing housed in the housing part is stopped by the restriction projection from bending to be led out straight, and can be bent at a position beyond a tip of the projection, so that the electric wire is bent and led out to the laterally led-out electric wire leading-out opening along a tip face of the restriction projection.

Description

  The present invention relates to a holding connector for a horizontal connector, and more specifically, it is used in a horizontal extraction process in which a group of electric wires connected to the connector is bent in one direction and pulled out, so that rapid bending of the electric wire on the side opposite to the extraction direction can be suppressed. This is related to the jig.

  As a connector to be connected to a wire harness routed in an automobile, an electric wire is often bent from the connector in one direction and pulled out, and the connector is called a lateral connector. The laterally extending connector may be laterally extended depending on the wiring direction of the wire harness, or may be laterally extended to interfere with an external interference material when the electric wire is drawn straight from the connector. Electric wires connected to this type of lateral connector are bundled in advance by extending the electrical wires connected to the connector in advance and arranging them in the direction before wiring in the automobile.

In the laterally extending connector, as shown in FIG. 11A, the electric wire W drawn out from the connector 210 and laterally extended is bent sharply from the terminal insertion port of the connector 210 and contacts the terminal insertion port of the connector 210. It may not be possible to secure the part straight. When the connector 210 is disposed in the flooded area, the waterproof rubber plug 220 is attached to the electric wire W at the insertion position into the connector 210. In that case, when the electric wire W is bent suddenly, as shown in FIG. 11B, a load is applied to the waterproof rubber plug 220 and deforms. As a result, a gap is generated between the waterproof rubber plug 220 and the electric wire W, and there is a risk of water in the connector 210.
From the above-described problems, it is required to secure a straight portion of the electric wire at a portion where the electric wire is inserted into the connector and suppress the electric wire from being bent suddenly.

  In order to solve the above problem, the present applicant has conventionally provided a lateral connector forming spacer disclosed in Japanese Patent Laid-Open No. 9-180853. As shown in FIG. 12 (A), after setting the connector 210 to the connector mounting portion 101 of the box jig 100 standing on the wire harness assembly work table, the spacer 110 is attached as shown in FIG. 12 (B). The upper wall 111 having a comb-teeth shape of the spacer 110 is overlapped on the upper surface of the connector 210, and the electric wire W connected to the connector 210 is pulled out through the notch 112 of the spacer 110 and then bent in the lateral direction. After that, the spacer 110 is pulled out from the connector mounting portion 101 to the front in the figure and removed, and as shown in FIG. The lateral connector can hold the electric wire of the connector 210 straight from the terminal insertion port by the thickness of the upper wall portion 111 of the spacer 110 by overlapping the spacer 110 with the connector 210.

Japanese Patent Laid-Open No. 9-180853

  When the spacer 110 is used, after setting the connector 210 to the connector mounting portion of the jig, it is necessary to attach the spacer 110 to the upper surface of the connector 210 while passing all the wires W through the notches 112 of the spacer 110. There is a problem that it takes time to pass all the wires connected to this connector through the notch 112 of the spacer 110. And since the electric wire of the inner peripheral side of a horizontal direction is also linearly hold | maintained only for the thickness dimension of the spacer 110 similarly to the outer peripheral side of an other side, a horizontal electric wire tends to swell. Therefore, as shown in FIG. 11A, there is a possibility of interference with the external interference material Z. Furthermore, since a separate spacer 110 from the connector holding jig is required, there is a problem that the jig cost becomes high.

  The present invention has been made in view of the above problem, and among the electric wires drawn out from the connector, the electric wire on the outer peripheral side can be prevented from abruptly being laterally bent to ensure a straight portion, and the inner peripheral side It is an object of the present invention to provide a holding connector for a side-by-side connector that can prevent the electric wire from expanding and that does not require a separate spacer.

In order to solve the above-mentioned problems, the present invention provides a connector insertion port and a lateral wire outlet opening in a direction orthogonal to the connector insertion port on a peripheral wall surrounding the connector housing accommodating portion, and the lateral wire outlet port. A restriction projection protruding from the inner surface of the peripheral wall at a position opposite to the terminal insertion port of the connector housing housed in the housing portion on the opposite side,
Of the electric wires connected to the connector housing accommodated in the accommodating portion, the electric wire on the side opposite to the lateral direction is prevented from being bent by the restricting projection and pulled straight, and can be bent at a position beyond the tip of the restricting projection. In addition, there is provided a holding connector for a horizontal connector, wherein the electric wire is bent and drawn out to the horizontal electric wire drawing opening along the tip surface of the restricting protrusion.

  As described above, simply by providing the holding protrusion integrally with the holding jig, it is possible to prevent the electric wire on the side opposite to the lateral direction from inclining from the base side connected to the connector and to hold the required dimension straight. . Therefore, a gap is formed between the waterproof rubber plug attached to the electric wire and the electric wire, and it is possible to prevent water from entering the connector from the gap. In addition, since a separate spacer from the jig is not required as in Patent Document 1, the jig cost can be reduced, and the work of attaching and removing the spacer becomes unnecessary.

  As a peripheral wall surrounding the housing portion of the connector housing, a bottom wall, left and right side walls projecting from both ends of the bottom wall, and a back wall are provided, the front is the connector insertion port, and the upper side of the right wall is the A horizontal lead-out wire outlet opening, a straight lead-out space between the left side wall and the restriction projection projecting from the rear wall, the regulation projection being a rectangular bar that is long in the vertical direction, and at the tip of the regulation projection The corresponding upper surface and the upper surface of the right side wall have the same height.

  The connector housing is inserted into the housing portion from the connector insertion opening with the electric wire connection side surface as the upper surface, and among the electric wires connected to the connector housing, the electric wire on the side opposite to the lateral direction is between the regulating projection and the left side wall. After being drawn through the straight lead-out space provided in the bent, bent along the upper surface of the restricting protrusion and drawn out to the laterally drawn electric wire outlet opening, and the other electric wires are extended along the upper surface of the right side wall. It is possible to make the horizontal part of the horizontal part with the same height.

It is preferable that a pressing wall that regulates the height of the protruding portion of the electric wire protrudes from a part of the peripheral wall surrounding the housing portion.
That is, by projecting the holding wall from the upper end of the back wall, covering the upper part of the housing portion, and extending a group of electric wires extending sideways along the lower surface of the holding wall, It is possible to prevent swelling in the vertical direction and to prevent interference between the laterally extending electric wire and the external interference material.

  Since the holding wall is located on the wire drawing side of the housing portion of the connector housing, the holding wall is hinged to the back wall, etc., rotated to a position where it does not get in the way when the connector is inserted, and the electric wire is bent. It is good also as a structure which returns a pressing wall to the original position which covers an accommodating part when carrying out sideways.

As described above, when the holding jig for the lateral connector according to the present invention is used, the electric wire on the outer peripheral side of the group of electric wires that are laterally extended from the lateral connector is easily bent in the pulling direction. However, the straight portion of the electric wire can be secured by the restricting protrusion provided integrally with the jig, and rapid bending is suppressed. Therefore, when a waterproof rubber plug is attached to the electric wire, the waterproof rubber plug is not deformed, and water can be reliably prevented from entering the connector.
In addition, unlike the Patent Document 1, a spacer separate from the holding jig is not required, and only the holding jig is required, so that the cost can be reduced and the work for assembling the spacer can be omitted.

Hereinafter, embodiments of a holding jig for a lateral connector according to the present invention will be described with reference to the drawings.
1 to 4 show a first embodiment.
The holding jig 1 is provided with a box-shaped connector housing portion 5 at the upper end of a support shaft 2 erected on a wire harness assembly work table 19. The connector housing portion 5 has an opening on the front surface and the top surface, and is a peripheral wall composed of a bottom wall 7, a right side wall 9, a left side wall 8, and a back wall 10, and a housing portion 6 for a lateral connector 20 (hereinafter simply referred to as a connector 20). Is enclosed. The front opening is the connector insertion port 3, the upper surface opening is the lead-out side of the electric wire W connected to the connector 20, and the upper side of the right side wall 9 is the side-out electric wire lead-out opening 4.

  A restriction projection 11 is projected from the upper end of the back wall 10 facing the connector insertion port 3 to the upper portion of the housing portion 6. The regulation protrusion 11 is rod-shaped and has a cross-sectional shape that is long in the vertical direction, but the left-right width direction has a short dimension substantially equal to the outer diameter of one electric wire W.

  As shown in FIG. 3, the connector 20 to be inserted into the holding jig 1 has a terminal insertion port 23 facing upward and extends sideways in the right direction (arrow X direction) in the drawing. The left side wall 8 of the holding jig 1 is on the side opposite to the electric wire lateral direction and is located on the outer peripheral side of the electric wire bent in the right direction. The right wall 9 is located on the inner peripheral side in the lateral direction.

  The upper surface 8u of the left side wall 8 and the upper surface 10u of the rear wall 10 which are the outer peripheral side have the same height, and the height dimension H1 is slightly larger than the dimension H2 of the connector housing 21 in the terminal insertion direction. Since the lower surface 11d of the restriction projection 11 protruding forward from the upper surface 10u of the back wall 10 is the same height as the upper surface 10u, the lower surface 11d of the restriction projection 11 is a terminal insertion port of the connector housing 21 accommodated in the accommodating portion 6. The upper surface 24 on which 23 is located is located above the upper surface 24 with a slight gap S1. The dimension of the gap S1 is 2 mm to 8 mm.

  Further, the restricting projection 11 is positioned with a space S2 from the inner surface 8a of the left side wall 8. The space S2 is a straight lead-out space, and the width of the space S2 is a width that allows the electric wire W1 on the outermost peripheral side of the connector 20 and the electric wire W2 adjacent to the right side of the electric wire W1 to pass therethrough. In addition, it is good also as a space which lets only one electric wire W1 of outermost periphery pass. Further, the width t of the restricting protrusion 11 is substantially equal to the outer diameter of the electric wire W. Furthermore, the height H3 of the restricting protrusion 11 is set to about 3 mm to 8 mm.

  The right side wall 9 in the lateral direction of the electric wire is made higher than the height of the left side wall 8 and the back wall 10 by a dimension corresponding to the height H3 of the restricting projection 11, and the height of the upper surface 9u of the right side wall 9 and the upper surface 11u of the restricting projection 11 is increased. Are equivalent. Further, the right side wall 9 has an inverted L shape in which an upper side protruding from the left side wall 8 is provided with an inner protrusion 9c, and the lower surface 9d of the inner protrusion 9c has the same height as the upper surfaces 8u and 10u.

  The connector 20 is connected to a terminal of an electric wire W that constitutes a wire harness 30 that is routed in an engine room that is a flooded area of an automobile and is connected to a device (not shown), and is waterproof. Specifically, the terminal connected to the terminal of the electric wire W is inserted and locked into each terminal accommodating chamber 22 from the terminal insertion port 23 of the connector housing 21 of the connector 20, and externally fitted to the electric wire W in the terminal insertion port 23. The waterproof rubber plug 33 is tightly fitted and penetrated, and the waterproof rubber plug 33 protrudes outward from each terminal insertion port 23.

  As described above, the connector 20 is preliminarily connected and temporarily bound to the end of the electric wire W of the wire harness 30, and the temporarily bound wire harness 30 is wired on the wire harness assembling work table 19. Insert into the holding jig 1 for the horizontal connector erected on the assembly work table 19, insert a terminal into the terminal insertion port 23 of the connector 20, and apply bending bends in the horizontal direction X to the connected wire W. In this state, the tape T is used for binding.

  Specifically, the connector 20 connected to the wire harness 30 is pushed into the housing portion 6 from the connector insertion port 3 of the connector housing portion 5 of the holding jig 1 and inserted. At the time of insertion, the terminal insertion port 23 connected to the electric wire W of the connector housing 21 is used as the upper surface, and the lower surface on the opposite side is inserted in sliding contact with the upper surface of the bottom wall 7. The upper surface 24 of the connector housing 21 can be inserted with a small space S1 from the lower surface 11d of the restricting protrusion 11 and the lower surface 9d of the inner protruding portion 9c of the right side wall 9, and the connector housing 21 is positioned and inserted into the accommodating portion 6. .

  When the connector housing 21 connected to the electric wire W is inserted, the electric wire W drawn from the terminal insertion port 23 is inserted while being drawn to the upper surface opening side. At that time, the electric wires W1 and W2 located on the left side wall 8 side are drawn out from the gap S2 between the left side wall 8 and the restricting projection 11, and the remaining electric wires W3 are drawn upward from S4 between the restricting projection 11 and the right side wall 9. .

  The electric wires W1 and W2 drawn upward from the gap S2 cannot be bent by the restricting projection 11 and are drawn straight. At a position beyond the tip of the restricting protrusion 11, the wire is bent rightward along the upper surface 11u and pulled out to the side of the wire outlet opening 4 side. The remaining electric wires W3 are bent to the right along the upper surface 9u of the right side wall 9 and run sideways. Since the upper surface 11u of the restricting projection 11 and the upper surface 9u of the right side wall 9 on the inner peripheral side have the same height, the electric wires W1 and W2 on the outer peripheral side and the electric wires W3 on the inner peripheral side and the intermediate position are higher in the bending direction. It is possible to bend in the horizontal direction with the same thickness. In this way, in a state where the electric wire W is bent and laterally extended and a bending ridge is attached, the tape T is wound around the electric wire group and bound as shown in FIG.

  After the electric wire W connected to the connector 20 is placed sideways, the connector 20 is taken out from the holding jig 1 together with the wire harness 30. At that time, the connector 20 is pulled forward from the connector insertion port 3 of the holding jig 1.

  As described above, the holding protrusion 1 is provided with the restricting projection 11 so that when the electric wire W connected to the connector 20 is bent sideways and bent, the outer wires W1 and W2 are subjected to a tensile load from the horizontal direction. Therefore, it is easy to incline in the lateral direction from the terminal insertion port 23 of the connector 20, but the electric wire W <b> 1 and W <b> 2 have a height dimension of the regulation projection 11 from the terminal insertion port 23 by the regulation projection 11 provided on the holding jig 1. Pulled straight up. In this way, it is possible to prevent the electric wires W from being inclined by the restricting protrusions 11, and therefore, it is possible to eliminate the generation of a gap in which water is generated between the waterproof rubber plugs 33 attached to the electric wires W 1 and W 2 and the electric wires, thereby waterproofing the waterproof connector. Performance can be increased.

  And since the bending position of the electric wire W drawn out from the connector 20 in the lateral direction is positioned by the upper surface 11u of the restricting protrusion 11 and the upper surface 9u of the right side wall 9, the height of the lateral electric wire from the terminal insertion port 23 is increased. It can be regulated to the set value. Therefore, when the connector 20 is connected to a device, the lateral electric wire W can be prevented from interfering with the external interference material.

5A and 5B show a first modification of the first embodiment.
In the first modification, the gap S2 between the restricting protrusion 11 and the left side wall 8 is provided at a position where only one electric wire W1 located on the outermost periphery is passed.
Since other configurations and operational effects are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

FIG. 6 shows a second modification of the first embodiment.
In the first embodiment, the connector 20 is inserted from the front opening of the holding jig 1 into the housing portion 6 in the horizontal direction from the front to the rear, and the electric wire is bent to have a horizontal protrusion and pulled out to the front. ing.
On the other hand, in the second modified example, the holding jig 40 is rotated 90 degrees, the upper surface opening is used as the connector insertion port 41, and the restriction projection 45 is projected from the right end surface 42a of the bottom wall 42 facing the connector insertion port 41. doing. A gap S2 between the restriction projection 45 and the rear side wall 43 becomes a drawing space for the electric wires W1 and W2 located on the outer periphery, and a space between the restriction projection 45 and the front side wall 44 becomes a drawing space for other electric wires. Other configurations are the same as those of the first embodiment.

In the second modified example, the connector 20 can be inserted downward from the connector insertion port 41 opened on the upper surface of the holding jig 40, and workability can be improved.
In addition, it is good also as a structure which can rotate and fix the connector accommodating part 5 with respect to the spindle 2 of the holding jig 1 of 1st Embodiment 90 degree | times.

7 and 8 show a second embodiment.
The holding jig 50 of the second embodiment is provided with a height regulating pressing wall 52 that regulates the upper surface of the electric wire W bent from the connector 20 and laterally extended. The pressing wall 52 has a height of the back wall 10 that is higher than that of the first embodiment, and protrudes from the upper surface 10 u of the back wall 10 so as to cover the upper portion of the housing portion 6.
A space S5 is provided between the pressing wall 52 and the upper surface 11u of the restricting protrusion 11 and the upper surface 9u of the right side wall 9 for inserting the electric wire W bent and laterally extended. The electric wire W is passed through the space S5 to prevent the electric wire W from bulging upward from the lower surface 52d of the pressing wall 52. Other configurations are the same as those of the first embodiment, and the same reference numerals are given and description thereof is omitted.

  As described above, the height H6 of the electric wire W bent and laterally extended can be held at a predetermined value simply by providing the holding wall 52 for regulating the height provided in the holding jig 50. As a result, it is not necessary to inspect the height of the laterally extending electric wire from the connector, which has been conventionally required, and the holding jig 50 can also be configured to serve as the inspection jig.

FIG. 9 shows a modification of the second embodiment.
In the modification, the pressing wall 52 for regulating the height is continuous via the hinge 55 so as to be openable and closable with respect to the back wall 10. When the connector 20 is inserted into the housing portion 6, the pressing wall 52 is rotated 90 degrees upward to be opened and retracted from a position covering the housing portion 6. Thereby, the connector 20 can be easily inserted into the accommodating portion 6.
After the connector 20 is inserted into the housing portion 6, the holding wall 52 is rotated to a position that covers the upper portion of the housing portion 6, and the height of the electric wire W that is bent and laid out is regulated.

This invention is not limited to the said embodiment, It is good also as a structure which shows a control protrusion in FIG. 10 (A)-(C).
As shown in FIG. 10A, in the case of a multi-pole large connector, a plurality of restricting protrusions 11 may be provided at intervals.
Further, as shown in FIG. 10 (B), it is preferable to provide a radius 11r at the corner of the restricting protrusion 11 in contact with the bending electric wire.
Furthermore, as shown in FIG. 10C, the upper end of the restricting projection 11 may be formed in an inverted J shape that bends in the lateral direction.
