Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal fitting fitted to a stud protruding from a device and a terminal assembly structure in which a plurality of the terminal fittings are combined.

[0002]

2. Description of the Related Art For example, when connecting a plurality of grounding wires constituting a wire harness of an automobile to a grounding stud bolt provided on a vehicle body, a terminal metal fitting is fixed to the end of each wire and It is performed that terminal fittings are sequentially stacked and fitted to stud bolts.

Conventionally, as a terminal fitting therefor, the one disclosed in Japanese Utility Model Publication No. 63-28536 is known. As shown in FIG. 15, the terminal fitting 1 has a circular connecting plate portion 2 having a fitting hole 2A for a stud bolt (not shown) in the center and an outer peripheral edge of the connecting plate portion 2 protruding outward. The electric wire 6 is connected to the electric wire connecting portion 3 by crimping. Two locking pieces 4, 4 are provided at symmetrical positions on the outer circumference of the connection plate portion 2, and each locking piece 4 has a lock receiving portion 5 that is raised above the upper surface of the connection plate portion 2.
However, it extends in the counterclockwise direction along the outer periphery of the connection plate portion 2 so that the locking piece 4 of the terminal fitting 1 overlaid thereon can be embedded. Further, the locking piece 4 is provided with a lock hole 4A penetrating both upper and lower sides thereof, and
The lock receiving portion 5 is formed with a protrusion 5A which can be fitted into the lock hole 4A by cutting and raising the lower surface side.

In order to assemble two terminal fittings 1 into a stud bolt, the connecting board 2 of the other terminal fitting 1 is concentrically and rotated on the upper surface of the connecting board 2 of one terminal fitting 1. When the upper connection plate portion 2 is rotated in the clockwise direction after the postures are shifted and overlapped, the locking piece 4 thereof sneaks under the lower lock receiving portion 5, and the lower terminal fitting 1 The protrusion 5A and the lock hole 4A of the upper terminal metal fitting 1 are fitted to each other to integrate the both terminal metal fittings 1, 1 as shown in FIG.

[0005]

However, when the terminal fittings 1 of this kind are superposed and integrated, as shown in FIG. 16, the lock receiving portion 5 is centered on the center point O of the fitting hole 2A.
The electric wire connecting portions 3 and 3 are opened by an angular interval θ formed by the locking piece 4 and the locking piece 4. Further, when the terminal fittings 1 are successively stacked, the electric wire connecting portions 3 of the respective terminal fittings 1 are helically aligned while being spaced counterclockwise about the center point O by an angular interval θ. Therefore, as the number of terminal fittings 1 to be stacked increases, the lowermost wire connecting portion 3
The angle formed by the extending direction of the electric wire 6 from and the extending direction of the electric wire 6 from the uppermost electric wire connecting portion 3 becomes large. In such a state that the number of the terminal fittings 1 overlapped and the electric wires 6 spread at a large angle, when all the electric wires 6 are bundled and wired in the same direction, the electric wires 6 located on the end side have a large curvature. The electric wire 6 is bent due to excessive stress, which causes a heavy load.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to reduce the load on an electric wire when a plurality of terminal fittings are superposed.

[0007]

According to a first aspect of the present invention, it is possible to assemble in a state in which the centers of the assemblies are overlapped with each other so that the centers thereof coincide with each other. And a plurality of terminal fittings, each of which has a locking piece and a locking receiving portion formed at predetermined angular intervals in the circumferential direction with respect to the electric wire connecting portion, the terminal fittings overlapping each other. However, due to the engagement of the locking piece of one of the terminal fittings and the locking receiving portion of the other terminal fitting, the positions of the wire connecting portions are displaced in the circumferential direction for positioning. An assembly structure of terminal fittings, which comprises a plurality of kinds of terminal fittings having different positions of the wire connecting portion with respect to the locking piece and the locking receiving portion in the circumferential direction, and the terminal fittings of the same type are mutually Wire connection part when stacking If the direction of displacement is the same for all types of terminal fittings, and if a terminal fitting of a different type is stacked on the terminal fittings group consisting of terminal fittings of the same type, this It is characterized in that the electric wire connecting portions of the various kinds of terminal metal fittings are displaced in the direction returning to the starting end side in the displaced arrangement of the electric wire connecting portions of the terminal metal fitting group, and the arrangement is started.

According to a second aspect of the present invention, in the invention of the first aspect, the deviation angle in the circumferential direction between the electric wire connecting portions in the one terminal metal fitting group in which the terminal metal fittings of the same type are overlapped with each other, and the one terminal metal fitting. The other terminal metal fittings of the same type and different from each other have the same deviation angle in the circumferential direction between the electric wire connecting portions in the other terminal metal fittings, and one terminal metal fitting group It is characterized in that the electric wire connecting portions corresponding to each other with the other terminal fitting group are arranged at positions displaced in the circumferential direction.

According to a third aspect of the invention, in the invention of the second aspect, the electric wire connecting portions corresponding to each other between the one terminal metal fitting group and the other terminal metal fitting group are parallel to each other. It is characterized by

[0010]

According to the first aspect of the invention, first, when a plurality of terminal fittings of the same type are superposed on each other and assembled, the electric wire connecting portions of the respective terminal fittings are arranged so as to be sequentially displaced in the circumferential direction. One group of terminal fittings is configured. Similarly, a plurality of terminal fitting groups are formed by assembling the terminal fittings for each type. In each terminal fitting group, the plurality of electric wire connecting portions are sequentially displaced in the circumferential direction, so that the electric wire connecting portions are spread over a predetermined angle range. The terminal assembling structure of the present invention is configured by stacking and assembling the plurality of terminal fitting groups.

When the different types of terminal fittings are assembled, the direction of the positional deviation of the wire connecting portion is opposite to that when the same type of terminal fittings are assembled. The expansion range of the connection portion does not continuously increase in the circumferential direction, but overlaps with the expansion range of the electric wire connection portion on the other side. Therefore, even if a plurality of terminal metal fitting groups are stacked and assembled, the expansion range of the electric wire connecting portion can be set within substantially the same range as the expansion range of the single terminal metal fitting group. With this, even if the number of terminal fittings increases, the expansion range of the wire connecting portion can be kept within a certain range.

According to the second aspect of the present invention, the electric wire connecting portion of the one terminal metal fitting group does not overlap with the electric wire connecting portion of the other terminal metal fitting group, and the electric wire connecting portion protrudes at a position displaced in the circumferential direction.

According to the third aspect of the invention, since the electric wire connecting portions corresponding to each other are made parallel to each other, the expansion range of the protruding end of the electric wire connecting portion is larger than that in the case where the corresponding electric wire connecting portions extend in different directions. Becomes smaller.

[0014]

According to the invention of claim 1, even if the number of terminal fittings increases, the expansion range of the electric wire connecting portion can be kept within a certain range. Therefore, all the electric wires connected to the electric wire connecting portion can be accommodated. When the wires are bundled together and wired in the same direction, the curvature of the electric wire that can be bent can be small, and it is possible to prevent an excessive bending stress from being generated in the electric wire and a large load.

According to the invention of claim 2, even when the height dimension of the wire connecting portion is larger than the overlapping thickness of the terminal fitting group, the wire connecting portions can be assembled without interfering with each other.

According to the third aspect of the invention, since the spread range of the projecting end of the electric wire connecting portion can be suppressed to be small, the bending curvature when the electric wires are put together is small, and the load on the electric wire can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The assembly structure of the terminal fittings in this embodiment is composed of two kinds of terminal fittings, that is, the lower terminal fitting 10 and the upper terminal fitting 20.
Are formed by superimposing each of them four by four.

First, the structure of the lower terminal fitting 10 will be described with reference to FIGS. The lower terminal fitting 10 is made of a conductive metal plate material, and includes a substantially circular connecting plate portion 11 and a barrel portion (electric wire connecting portion) 12 that integrally projects from an outer peripheral edge of the connecting plate portion 11. The barrel portion 12 is composed of an insulation barrel portion 12A that is crimped to the coating portion Wa of the electric wire W and a wire barrel portion 12B that is crimped to the exposed core wire Wb. In the center of the connecting plate portion 11, a fitting hole 13 that penetrates through the upper and lower surfaces is formed.
Is formed, and the fitting hole 13 is adapted to be fitted with, for example, a stud bolt (not shown) provided on the body of the automobile. Further, the barrel portion 12 extends in the radial direction from the center point P of the fitting hole 13 and is curved so that both side edges thereof rise upward. An electric wire W is connected to the barrel portion 12 in an electrically conductive state by crimping, and the crimped electric wire W extends in the radial direction from the center point P like the barrel portion 12.

The barrel portion 12 on the outer periphery of the connecting plate portion 11
An edge portion 14 is formed at a position opposite to the edge portion 14 so as to have a partially increased outer diameter.
Are arranged on a concentric circle centered on the center point P, and the locking piece 1
5 and a locking hole (lock receiving portion which is a constituent of the present invention) 16 are formed. The locking piece 15 is formed by partially raising the edge side portion 14 to the upper side, and is inclined so that the clockwise side in FIG. 2 represented by a plane becomes higher. On the other hand, the locking hole 16 is formed so as to penetrate from the upper surface to the lower surface of the edge side portion 14, and when the fitting holes 13 are aligned and the two lower terminal fittings 10, 10 are superposed in a normal state, As shown in FIG. 4, the lower terminal fittings 10, 10 are displaced in the circumferential direction so that the engaging hole 16 of the upper lower terminal fitting 10 and the engaging piece 15 of the lower lower terminal fitting 10 are engaged with each other. It is like this.

In addition, on the outer periphery of the connecting plate portion 11 at a position adjacent to the edge side portion 14 on the clockwise side, and at a position spaced by an angle of about 180 ° (clockwise 185 °) from this position. , And a respective submerged plate portion 17 is formed.
Each of the submerged plate portions 17 is formed with a rising prevention piece 18 that is folded up in a U-shape so as to rise from the outer edge of the submerged plate portion 17 and overhang on the submerged plate portion 17. A protrusion 19 protruding upward is formed on the clockwise side of the piece 18.

When the two lower terminal fittings 10 and 10 are stacked and the upper lower terminal fitting 10 is rotated relatively clockwise, the upper submerged plate portion 17 of the lower floating prevention piece 18 is moved. It goes under and the projection 19 is pressed against the lower surface. Engagement of the submerged plate portion 17 and the lifting prevention piece 18 prevents the lower terminal fittings 10 and 10 from being separated from each other in the vertical direction, and friction between the rising prevention piece 18 and the protrusion 19 prevents both lower steps. The terminal fittings 10, 10 are prevented from easily rotating relative to each other in the circumferential direction, so that the lower terminal fittings 10, 10 are assembled in a normal state in a predetermined relative positional relationship as shown in FIG. In this state, the upper lower terminal metal fitting 10 is rotated relative to the clockwise direction so that the upper and lower floating preventing pieces 18,
18 are prevented by abutting each other, and conversely, counterclockwise relative rotation is prevented by engagement of the locking piece 15 and the locking hole 16.

The edge portion 1 on the clockwise side of the submerged plate portion 17
7A is crushed so that the upper surface is inclined to form a wedge shape. With such a shape, when the stacked lower terminal metal fittings 10 are relatively rotated and the upper submerged plate portion 17 is submerged under the lower floating prevention piece 18, a catch is less likely to occur. The work of assembling the lower terminal fitting 10 is facilitated.

When the assembled lower terminal fitting 10 is removed, the lower locking piece 15 exposed from the locking hole 16 is elastically deformed by a jig such as a screwdriver and pushed down to lock with the locking piece 15. Release the engagement of hole 16,
From this state, the upper lower terminal metal fitting 10 may be relatively rotated counterclockwise.

Next, the positional relationship between the locking pieces 15 and the locking holes 16 in the lower terminal fitting 10 and the positional relationship between these and the barrel portion 12 will be described with reference to FIG.
In the circumferential direction around the center point P, the locking piece 15 is arranged at a position counterclockwise with an angular interval of 30 ° with respect to the locking hole 16, and the barrel portion 12 has the locking piece 15. In contrast, they are arranged counterclockwise with an angular interval of 170 °.

The angle between the locking piece 15 and the locking hole 16 is set so that the locking piece 15 and the locking hole 16 are engaged when the lower terminal fittings 10, 10 are combined. The reference is based on the angular interval between the surfaces that are in contact with each other. Further, how to set the angle between the locking piece 15 and the barrel portion 12 is determined by the contact surface of the locking piece 15 with the locking hole 16 and the width direction (circumferential direction) of the barrel portion 12. The angle interval between a radial center line passing through the center (hereinafter referred to as a reference position Q) is used as a reference.

With this arrangement, in the state where the two lower terminal metal fittings 10 and 10 are stacked and assembled in the normal state, the upper barrel portion 12 is the lower barrel portion 12 as shown in FIG. On the other hand, they are arranged with the angular interval of 30 °, which is the same as the distance between the locking piece 15 and the locking hole 16, shifted in position counterclockwise.

When the four lower terminal fittings 10 are sequentially stacked and assembled in a normal state, as shown in FIG. 5, the lowermost barrel 12 and the uppermost barrel 12 have an angular interval of 90 °. And the uppermost locking piece 15 is arranged at an angular interval of 80 ° clockwise with respect to the lowermost barrel portion 12. The angle interval of 80 degrees is the same as the angle interval between the locking hole 26 and the barrel portion 22 in the upper terminal fitting 20 described later.

Next, the upper terminal fitting 20 will be described with reference to FIGS. 6 to 10. Similar to the lower terminal metal fitting 10, the upper terminal metal fitting 20 has a barrel portion (electric wire connection portion) to which the electric wire W is connected to the connection plate portion 21 in which the fitting hole 23 is formed.
22, the edge side portion 24 in which the locking piece 25 and the locking hole (lock receiving portion) 26 are formed, the position adjacent to the edge side portion 24 in the clockwise direction, and this position about 180 ° (185 in the clockwise direction). °)
And submerged plate portions 27 respectively formed at positions spaced by angular intervals.

Locking piece 25, locking hole 26, submerged plate portion 27,
Lifting prevention piece 28 and protrusion 29 formed on the submerged plate portion 27.
Are arranged on a circle having the same center point P as that of the lower terminal fitting 10 and having the same radius. Therefore, when the upper terminal metal fitting 20 is stacked on the lower terminal metal fitting 10, the engagement between the lower locking piece 15 and the upper locking hole 26 and the upper diving plate 27 and the lower floating material. The upper and lower terminal fittings 10 and 20 are assembled by engaging with the anti-rotation piece 18. Of course, even when the upper terminal fittings 20 are overlapped with each other, the engaging pieces 25 and the engaging holes 26 engage with each other and the submerged plate portion 27 and the floating preventing piece 28 engage with each other. Can be assembled.

When assembling the lower terminal fitting and the upper terminal fitting and assembling the upper terminal fittings from each other, since the edge portion 27A of the submerged plate portion 27 is inclined like a wedge, the submerged plate portion 27 is formed. When it is made to sink under the lifting prevention pieces 18 and 28, it is hard to be caught.

The positional relationship between the locking piece 25 and the locking hole 26 is as follows.
Like the lower terminal fitting 10, the locking piece 25 is arranged at a position counterclockwise with an angular interval of 30 ° with respect to the locking hole 26 (see FIG. 7), and the two upper terminal fittings are arranged. 20,
In a state in which 20 is assembled in a normal state, as shown in FIG. 9, the upper barrel portion 22 is arranged at an angle of 30 ° with respect to the lower barrel portion 22 and is displaced counterclockwise. Will be done. When the four upper terminal fittings 20 are sequentially stacked and assembled in a normal state, as shown in FIG. 10, the lowermost barrel portion 22 and the uppermost barrel portion 22.
And become 90 degrees apart and spread out.

The positional relationship between the barrel portion 22 of the upper terminal fitting 20 and the locking hole 26 is different from the positional relationship between the barrel portion 12 and the locking hole 16 of the lower terminal fitting 10. The reference position R of the barrel portion 22 in the circumferential direction around the center point P is a position counterclockwise with an angular interval of 80 ° with respect to the locking hole 26, as shown in FIG. 7.

Now, the relationship between the barrel portion 22 and its reference position R will be described. Reference position R is lower terminal fitting 1
In order to make the positional relationship of 0 with the barrel portion 12 easy to understand, it is represented by a straight line extending in the radial direction from the center point P similarly to the position reference Q of the barrel portion 12 (see FIG. 7).
On the other hand, the position where the barrel portion 22 is actually formed is parallel to the reference position R and is displaced clockwise. By thus setting the actual forming position of the barrel portion 22 and the reference position R so as to be offset from each other, the reference positions Q and R of the lower barrel portion 12 and the upper barrel portion 22 in the assembled state, which will be described later, are set. It becomes possible to prevent the lower barrel portion 12 and the upper barrel portion 22 from interfering with each other.

The angle interval of 80 ° formed by the reference position R of the barrel portion 22 with respect to the locking hole 26 is the same as the lowermost barrel portion 12 in the state where four lower terminal fittings 10 are assembled as described above. It is the same as the angular interval between the uppermost locking piece 15. The uppermost locking piece 15 is engaged with the locking hole 26 of the upper terminal fitting 20.

Therefore, in a state where the upper terminal metal fitting 20 is assembled on the terminal metal fitting group in which four lower terminal metal fittings 10 are assembled, the barrel portion 22 of the upper terminal metal fitting 20 is the barrel of the uppermost terminal metal fitting 10. As shown in FIG. 12, the reference position R of the barrel portion 22 on the upper stage side is not located so as to spread further counterclockwise with respect to the portion 12, but the reference position R of the lowermost barrel portion 12 of the lower terminal metal fitting group 10 is. It will coincide with the position Q. That is, the same type of lower terminal metal fitting 1
When assembling 0 and 10 with each other, the barrel part 12 shifts counterclockwise by 30 ° (see FIGS. 4 and 5), while the lower terminal fitting 10 is different from the upper terminal fitting. When 20 is assembled, as shown in FIG. 11, the barrel portion 22 on the upper side is the barrel portion 12 on the lower side.
A large 90 ° offset to return clockwise with respect to the above, therefore, as shown in FIG. 12, the barrel portion 22 on the upper stage side should be arranged at the same position as the start position of the displacement of the barrel portion 12 on the lower stage side. become.

Then, further from the state shown in FIG.
When the upper terminal fittings 20 are stacked and assembled in order,
These barrel parts 22 are the same as the lower terminal metal fittings 10 and 3
The reference positions Q and R of the barrel portions 12 and 22 corresponding to the upper and lower sides are arranged in a counterclockwise position with an angular interval of 0 ° and are displaced from each other.

When the reference positions Q and R of the upper and lower barrel portions 12 and 22 are coincident with each other in this way, the upper barrel portion 22 is formed deviating from the reference position R as described above. , The upper barrel portion 22 is disposed in a position parallel to the lower barrel portion 12 in the clockwise direction with the posture parallel to the lower barrel portion 12, whereby both the upper and lower barrel portions 1 are arranged.
The interference between 2 and 22 is avoided.

The lower terminal fitting 10 and the upper terminal fitting 2
Assembling 4 pieces of 0 each is as follows:
Assemble the 0s in sequence one by one, and then attach the upper terminal fitting 20
Even with the method of assembling one by one, four lower terminal metal fittings 1
0 may be assembled to form the lower terminal metal fitting group, four upper terminal metal fittings 20 may be assembled to form the upper terminal metal fitting group 20, and then both terminal metal fitting groups may be assembled.

The total number of the terminal fittings constituting the two terminal fitting groups in the present embodiment is eight, but when the same eight kinds of the terminal fittings are stacked and shifted by 30 °, the barrel parts are assembled. The angle of divergence is as large as 210 °, and when the wires connected to these barrels are bundled and wired in the same direction, the wires located closer to the end side will be bent with a larger curvature and a larger bending stress will occur. become.

On the other hand, in this embodiment, the eight terminal metal fittings 10 and 20 are divided into two terminal metal fitting groups and vertically assembled, so that the barrel portion 1 as a whole is assembled.
The spread range of 2, 22 is set within an angle range slightly larger than the spread range of 90 ° which is the spread range of the barrel portions 12, 22 of one terminal fitting group. Therefore, when the eight electric wires W connected to the barrel portions 12 and 22 are bundled and wired in the same direction, the curvature of the electric wire W that can be bent is small, and an excessive bending stress is generated in the electric wire W, resulting in a burden. It doesn't take big.
