Description

  The present invention relates to a ground terminal fixing structure, and more particularly, in a structure in which a ground terminal connected to a wire harness routed in an automobile and a molded product such as a protector for protecting the wire harness are fastened together with bolts to a vehicle body panel, The ground terminal is accurately positioned at a predetermined position of the molded product with one touch so that the bolt holes can be matched.

  Conventionally, when a wire harness is inserted into a molded protector in order to maintain and maintain the wiring posture of the automotive wire harness, as shown in FIGS. 9A and 9B, the ground wire 2 used for the wire harness The ground terminal 3 connected to the terminal is overlapped with a protector fixing seat 5 for fixing the protector 1 to the vehicle body, and bolts (not shown) are provided in the bolt hole 6 provided in the seat 5 and the bolt hole 4 of the ground terminal 3. The protector 1 and the ground terminal 3 may be fastened and fixed to the vehicle body panel with the bolt (see Japanese Utility Model Laid-Open No. 6-5322 (Patent Document 1)).

  Thus, when the ground terminal 3 is overlapped on the seat portion 5 and fastened with bolts, it is necessary to match the bolt hole 6 of the seat portion 5 with the bolt hole 4 of the ground terminal 3.

  In this regard, the seat portion 5 of the protector 1 projects downward with a pair of elastic locking pieces 5b facing the inner side of a locking plate 5a erected on both sides of the seat portion 5. By elastically bending the locking piece 5b and pushing the ground terminal 3, the step locking claw 5c provided at the tip (lower end) of the elastic locking piece 5b is engaged with both sides of the ground terminal 3, and The guide protrusion 5d provided on the seat portion 5 is inserted in the middle of the barrel 3a of the ground terminal 3 so that the superposition posture of the ground terminal 3 and the seat portion 5 is fixed.

  However, this fixing structure can restrict the ground terminal 3 from being lifted up, rotated, or displaced in the left-right direction, but cannot be effectively regulated from being displaced in the front-rear direction. There was a problem in that the hole 4 and the bolt hole 6 of the seat portion 5 were easily misaligned, and the workability of tightening with bolts was poor.

  Further, in the fixing structure, since only one ground terminal can be fixed to the seat portion, in the automotive wiring harness in which many ground terminals are used, the number of bolts and bolts for fixing the ground terminals to the vehicle body panel There was also a problem that the number of tightening operations increased.

  On the other hand, the present applicant, in Japanese Patent Application Laid-Open No. 7-263043 (Patent Document 2) related to another earlier application, aligns with a molded product with one touch in a state where two ground terminals are overlapped, and tightens with a bolt. A possible structure is proposed.

  Specifically, as shown in FIGS. 10 and 11, on the upper surface of the bracket portion 100 of the electrical junction box, the concave portion 101 for positioning the ground terminal 106, the front convex portion 102, the rear convex portion 103, the upper convex portion 104, The bridge portion 105 is formed, and when the two overlapping ground terminals 106 and 106 are slid into the recess 101 from the back of the bridge portion 105, the ground terminals 106 and 106 are prevented from rotating by the recess 101, and the front protrusion The front portion is positioned by 102, the rear portion is positioned by the rear convex portion 103 which has been elastically restored, the upper portion is positioned by the upper convex portion 104, and further, the bridge portion 105 regulates the floating of the ground terminals 106 and 106. The bolt holes 106a, 106a of the ground terminals 106, 106 and the bolt holes 107 of the bracket portion 100 can be obtained only by inserting the slide It has a structure which can be precisely aligned.

  However, in order to accurately align the two ground terminals connected to the ends of the two ground wires drawn from the same direction with the fixing structure, the ground terminals 106, 106 are set to 2 like the ground terminal 106. When the sheets are stacked, the wire crimping portions 106b and 106b do not overlap each other, and as shown in FIG. 11, the wire crimping portions 106b and 106b are limited to those having a gap A in which the rear convex portion 103 enters. Accordingly, a terminal having a bolt hole 108a on the axis of the wire crimping portion 108b, such as the ground terminal 108 shown in FIG. 12A, or a bolt hole, like the ground terminal 109 shown in FIG. In the terminal where the step B is provided by inclining the continuous part of the electric contact part 109a provided with 109c and the electric wire crimping part 109b for crimping and connecting the electric wire, the rear convex part 103 enters when the two sheets are stacked. It is not or cannot be engaged well, and the rear part of the ground terminal cannot be positioned.

  In addition, the fixing structure has a problem in that it takes time to mold a molded product due to the presence of the bridge portion 105 and the cost is increased.

Japanese Utility Model Publication No. 6-5322 Japanese Patent Laid-Open No. 7-263043

  The present invention has been made in view of the above problems, and aligns the bolt hole of the ground terminal and the bolt hole of the molded product when the molded product such as a protector and the ground terminal are fastened to the vehicle body panel with the bolt. It is an object of the present invention to provide a low-cost ground terminal fixing structure that can be fastened by overlapping two ground terminals without using a special-shaped ground terminal.

In order to solve the above-mentioned problems, the present invention is arranged such that two ground terminals, a first ground terminal and a second ground terminal, are arranged on a fixing base provided with a bolt hole, and the fixing base is attached to the vehicle body through the bolt hole. A ground terminal fixing structure for connecting the two ground terminals to the vehicle body panel at the same time as fixing to the panel,
The fixing base is provided with a recessed portion for receiving the first ground terminal with the electric wire crimping portion facing downward, and the electric wire crimping portion of the first ground terminal is accommodated in the terminal receiving concave portion. In this state, the bolt hole of the first ground terminal communicates with the bolt hole of the fixing base, and the upper surface of the first ground terminal is the same height as the surface of the fixing base or higher than the surface of the fixing base, And,
An electrical contact portion guide projection for positioning and holding the electrical contact portion of the second ground terminal and a wire crimping portion guide projection for positioning and holding the wire crimp portion of the second ground terminal are projected on the fixed base,
When the electric wire crimping portion of the second ground terminal faces upward and the second ground terminal is mounted on the fixed base with the electric contact portion guide protrusion interposed therebetween, the second ground terminal and the first ground terminal The grounding surface is characterized in that the entire surface or a part thereof overlaps, and the bolt hole provided in the electrical contact portion of the first ground terminal and the bolt hole provided in the fixing base are in communication with each other. A terminal fixing structure is provided.

  Thus, by forming the terminal receiving recess for fitting the first ground terminal into the fixing base, the first ground terminal can be easily positioned on the fixing base simply by fitting the first ground terminal into the terminal receiving recess. The electrical contact portion guide projection for the second ground terminal can be formed on the fixed base, and the peripheral edge portion of the electrical contact portion of the second ground terminal is brought into contact with the guide projection, The second ground terminal can be easily positioned and mounted on the fixed base with one touch.

  Therefore, the two ground terminals can be easily positioned and mounted on the fixed base only by sequentially fitting the first ground terminal and the second ground terminal into the fixed base, and at the same time, the bolt hole of the first ground terminal and the second ground terminal Since the bolt hole of the ground terminal and the bolt hole of the fixing base can be communicated with each other without displacement, the bolt hole alignment work becomes unnecessary, and the joint tightening workability can be improved. In addition, since the two ground terminals and the fixing base can be fastened and fixed to the vehicle body panel with one bolt, the number of parts and the number of bolts can be reduced.

  Furthermore, the upper surface of the first ground terminal fitted in the terminal receiving recess is in the same height as the surface of the fixing base or higher than the surface of the fixing base, so that the electrical contact portion of the first ground terminal And the electric contact part of the 2nd earthing terminal piled up on it can make a strong surface contact, and can be grounded reliably.

  Further, since the wire crimping portion of the first ground terminal can be accommodated downward in the terminal receiving recess of the fixing base, it is not necessary to avoid the overlapping of the wire crimping portions of the two ground terminals. Can be mounted on the fixed base with the wire crimping portion facing downward and the second ground terminal being stacked with the wire crimping portion facing upward. Therefore, even if you want to pull in the ground wire connected to the two ground terminals from the same direction, there is no need to use a specially shaped ground terminal where the wire crimping parts do not overlap vertically as in the past. It is possible to stack two sheets using a general-shaped ground terminal having a bolt hole on the axis and to fasten them together with bolts.

The fixing base is continuously provided with a wire receiving recess for receiving the ground wire portion crimped to the first ground terminal in the terminal receiving recess, and the ground wire extends from the upper surface of the fixing base into the wire receiving recess. You may pull in.
In this case, when the drawing direction of the ground wire connected to the first ground terminal is the same as the drawing direction of the ground wire connected to the second ground terminal, the electric contact portion guide protrusion for the second ground terminal is A pair of protrusions are arranged around the terminal receiving recess for the first ground terminal, and a pair of the wire crimping portion guide protrusions for the second ground terminal are provided on both sides of the wire receiving recess for the first ground terminal. It is preferable to do.

On the other hand, when the pulling direction of the ground wire connected to the first ground terminal is different from the pulling direction of the ground wire connected to the second ground terminal, the first ground terminal and the second ground terminal rotate in the rotation direction around the bolt hole. This can be dealt with by arranging and designing the receiving recesses for the first ground terminal and the guide protrusions for the second ground terminal so that they are positioned out of alignment.
In this case, the rear end side of the terminal receiving recess for the first ground terminal or the rear end side of the wire receiving recess continuing to the terminal receiving recess is opened to the side of the fixed base so that the first ground terminal It is good also as a structure which draws in the connected earth wire in the terminal accommodating recessed part from the side opening part of this fixing stand.

  The fixing base comprises a protector fixing seat provided on a protector that passes through a wire harness routed to an automobile, and the ground in the wire harness that passes through the protector when the protector is bolted and fixed to a vehicle body panel. The wire is grounded to the body panel.

  The electrical contact portions of the first ground terminal and the second ground terminal have a rectangular shape or an elliptical shape, and the electrical contact portion guide protrusions are in contact with the outer surfaces of both corners on the distal end side of the second ground terminal. An electrical contact portion guide projection, a second electrical contact portion guide projection that comes into contact with the outer surfaces of both corners on the rear end side of the electrical contact portion of the second ground terminal, and an electric power of the second ground terminal that returns after elastic deformation It is preferable that the upper surface of the contact portion is composed of a third electric contact portion guide protrusion covering from both sides.

  As a result, the tip of the second ground terminal is positioned by the first electrical contact portion guide projection, the rear end is positioned by the second electrical contact portion guide projection, and both the left and right sides and the upper surface are the third electrical contact portion guide projection. Therefore, the second ground terminal can be reliably positioned and mounted on the fixed base. Furthermore, since the said fixing stand positions and fixes a 2nd earth terminal by hold | maintaining an electrical contact part with these 1st-3rd electrical contact part guide protrusions, the continuous part of an electrical contact part and a wire crimping part inclines. Alternatively, even a ground terminal having a bent shape can be reliably positioned and fixed to the fixing base.

  In addition, since the fixing base is not provided with a bridge-like pressing structure for the second ground terminal, the fixing base can be processed in a short time at a low cost, and the first and second ground terminals are also provided. It is not necessary to insert these ground terminals by sliding when mounting them on the fixed base, and they can be simply pushed in from the top surface.

  When the second ground terminal is provided with a step by bending or inclining the continuous portion of the electrical contact portion and the wire crimping portion, the wire crimping portion guide protrusion provided on the fixing base is wire crimping It is preferable to have a shape that can hold the part raised up. Thereby, the electrical contact portion of the second ground terminal can be held parallel to the electrical contact portion of the first ground terminal, and the electrical contact portion of the second ground terminal is lifted from the electrical contact portion of the first ground terminal. Can prevent contact failure.

  As described above, in the ground terminal fixing structure of the present invention, the first ground terminal is fitted into the terminal receiving recess of the fixing base, and the electrical contact portion of the second ground terminal is pushed in along the electrical contact portion guide protrusion. Thus, each of the first ground terminal and the second ground terminal can be positioned and mounted on the fixed base with one touch. Therefore, it is not necessary to align the bolt holes of the first ground terminal and the second ground terminal and the bolt holes of the fixing base, and it is possible to improve the joint tightening workability. In addition, since the two ground terminals and the fixing base can be fastened and fixed to the vehicle body panel with one bolt, the number of bolts and the number of bolt tightening steps can be reduced.

  Further, since the first ground terminal is mounted on the fixing base with the wire crimping portion facing downward and the wire crimping portion of the second ground terminal facing upward, the two ground terminals can be mounted even when the wire crimping portions are stacked vertically. The electrical contact portion can be brought into surface contact. Therefore, even if the ground wires connected to the two ground terminals are pulled in from the same direction, there is no need to use a specially shaped ground terminal where the wire crimping part does not overlap vertically, and there is a bolt hole on the axis of the wire crimping part. It is possible to fasten together by using a ground terminal having a general shape provided with the two and mounting the two ground terminals on the fixing base.

  Further, since the bridge is not provided with a bridge-like pressing structure as a grounding terminal positioning and holding structure, the mold of the fixing base can be processed in a short time and at a low cost.
