An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an electric wire connecting terminal 20 of the embodiment together with a stud bolt 1, and FIG. 2 is an electric wire connecting terminal 20.
2A is a diagram showing the details of FIG. 3A, FIG. 3A is a plan view, and FIG. The electric wire connecting terminal 20 is integrally formed by cutting a metal plate into a predetermined shape and bending it. The electric wire connecting terminal 20 has a cylindrical body 21 as a connecting portion for the stud bolt 1 at a tip end, and a base end portion. Has a wire crimping portion 6 as a wire connecting portion. 2 is an electric wire.

The wire crimping portion 6 is formed on a strip-shaped base plate 33, and the tip of the base plate 33 is formed on the peripheral wall of the cylindrical body 21 with its axis (axis of rotation) oriented perpendicular to the base plate 33. It is integrally joined to the lower edge. The entire width of the tip of the substrate 33 is integrally connected to the peripheral wall of the cylindrical body 21.

The cylindrical body 21 is formed in such a size that it can be fitted to the outer periphery of the stud bolt 1. Cylindrical body 21
Rolls a strip of metal plate continuous with the substrate 33,
It is formed by aligning the tips, and the mating portion is split 22. Bending pieces 23, which are bent inwardly of the cylindrical body 21 at approximately right angles, are formed at both circumferential edges of the cylindrical body 21 adjacent to the split 22.

The bending piece 23 is formed over the entire length of the cylindrical body 21 in the axial direction, and both bending pieces 2
The outer side surfaces of 3 and 23 are in close contact with each other to close the split portion 22. The front end surfaces (inner end surfaces) 23a, 23a of the bending pieces 23, 23 in the bending direction are in close contact with the peripheral surface of the stud bolt 1, and the bending pieces 23, 23 themselves hold down the rattling of the terminal 20. It is designed to fulfill the function of. Therefore, the rattling press 23
Are arranged to face the locking claws 31. Since the locking claw 31 closely faces the outer circumference of the bolt and the locking claw 31 are opposed to each other, the locking claw 31 is reliably engaged with the thread groove. Since the engagement between the locking claw 31 and the bolt 1 can be strengthened, the terminal can be reliably prevented from coming off.

The position where the bending pieces 23, 23 having the function of the backlash are present, that is, the position where the split 22 is present and the position where the joint between the substrate 33 and the cylindrical body 21 is opposed to each other. A flat portion (flat wall) 28 that is not curved is formed on the peripheral wall of the cylindrical body 21 having a groove. The flat portion 28 is a portion having a function as a connecting plate continuous with the substrate 33, and the stud bolt 1 is provided between the flat portion 28 and the tip end surface 23 a of the bending piece 23.
Is sandwiched between. Since the peripheral wall on the joint side is not curved, even if a lateral force is applied to the cylindrical body 2, the peripheral wall on the joint side is less likely to bend or buckle, and the rigidity is further improved. Since the flat wall is provided, the rigidity of the peripheral wall on the joint side with the substrate is further increased.

Since the flat portion 28 is not curved, it is hard to bend even if a crushing force is applied to the cylindrical body 21 from the lateral direction. Moreover, since the lower end portion is integrated with the substrate 33 and the connecting portion has an L-shaped cross section, the rigidity of the periphery thereof is further enhanced.

In the corner formed by the flat portion 28 and the substrate 33,
Further, ribs 35 are provided, and the reinforcing effect of the ribs 35 enhances both the strength of the flat portion 28 itself and the strength of the connecting portion between the substrate 33 and the flat portion 28. The rib 35 is formed in a mountain shape in cross section by convexly deforming the end portion of the substrate 33 from the bottom to the top, and has a sufficient reinforcing effect against a force from various directions or a twisting force. To be able to exert. Since the rib 35 has a chevron cross section, the reinforcing strength is further increased, and not only against the vertical force (the force within the plane including the axis of the cylindrical body) but also from the lateral direction (orthogonal to the vertical force). Strength) and the torsional force, the reinforcing strength is also improved. Also, the substrate 3
Since the rib was formed by deforming the end part of 2,
Good workability and cost effective. Therefore, the reinforcing strength against the force in various directions is increased, and the rigidity is further improved. Further, when the ribs 35 are provided, the processing is easy and the cost can be reduced.

At the upper end of the flat portion 28 having increased rigidity, two cut lines 2 are formed on the flat portion 28 from the upper edge.
By inserting 9 and 29 and cutting and raising the part between them, the locking claw 31 is formed. This locking claw 3
1 has a tip protruding obliquely upward, and a portion of the tip cut at an acute angle is a threaded portion 1 of the stud bolt 1.
It is adapted to engage with the groove (screw groove) of a. The locking claw 31 is provided on the joint side between the substrate 33 and the cylindrical body 21. Since the rigidity of the peripheral wall on the joint side with the board is increased, even if an inadvertent force is applied, the locking claw 3 at that portion
2 is less likely to come off the screw groove. Since the locking claws 31 are less likely to come off, the fixing force between the terminal and the bolt 1 increases. The locking claw 31 is provided on the side opposite to the joint side between the substrate 33 and the cylindrical body 21. Since the locking claw 31 is provided on the side opposite to the side of the joint with the highly rigid board 33, the locking claw 31 can be removed from the thread groove while deforming the peripheral wall of the cylindrical body with a small force. improves.

Further, on the inner surface of the cylindrical body 21, an elastic piece 27 that elastically presses against the peripheral surface of the stud bolt 1 is provided. The elastic piece 27 has a flat portion 2 and a position where there is a split 22.
8 are arranged in the middle of a certain position, and a pair is provided so as to face each other. Since there are a pair of the elastic pieces 27 facing each other, the elastic pieces are pressed against the bolt 1 in a well-balanced manner, the displacement of the contact portion hardly occurs, and the stable contact state can be maintained. Elastic piece 21 and bolt 1
Since the contact state of is stable, the reliability of the electrical connection is increased. Each elastic piece 27 has two parallel cut lines 25, 25 extending in the circumferential direction on the peripheral wall of the cylindrical body 21.
It is formed by pushing the part between the cut lines 25 of the book into the inside of the cylindrical body 21 while curving it in an arc shape, and both ends in the circumferential direction of the book are integrally supported by the cylindrical body 21. . The elastic piece 27 curved in an arc shape is configured to flexibly press the peripheral surface of the stud bolt 1 with its convexly curved outer surface.

Next, the operation will be described.

When this terminal 20 is used, first, the wire crimping portion 6 is crimped and fixed to the end portion of the wire 2, and then the cylindrical body 21 of the terminal 20 is placed with the side having the substrate 33 facing down. Fit to 1. Then, the arc-shaped outer peripheral surface of the elastic piece 27 is brought into pressure contact with the peripheral surface of the stud bolt 1, and the terminal 20 and the stud bolt 1 are reliably electrically connected.

At this time, since there are a pair of the elastic pieces 27 facing each other, the elastic pieces 27 are pressed against the stud bolt 1 in a well-balanced manner, the displacement of the contact portion hardly occurs, and the stable contact state is maintained. It

Further, since the elastic piece 27 is composed of the arcuate curved piece supported at both ends, even if it is a small elastic piece,
Stud bolt 1 that can exhibit sufficiently large elasticity and flexibility
Even if there is a slight difference in the diameter of the stud bolt 1, the stud bolt 1 is stably pressed against a peripheral surface in a large area. The spring force of the elastic piece 27 can be adjusted by adjusting the width and length of the two score lines 25, 25.

Further, by fitting the cylindrical body 21 into the stud bolt 1, the locking claw 31 is engaged with the groove of the threaded portion 1a of the stud bolt 1, whereby the cylindrical body 21 is prevented from coming off. In this case, since the locking claw 31 is projected obliquely upward, when the cylindrical body 21 is fitted into the stud bolt, the stud bolt 1 enters the locking claw 31 in the forward direction, so that the cylinder easily The body 21 can be fitted.

Prevent 21 from slipping out.

Further, since the locking claw 31 is arranged on the flat portion 28 having particularly high rigidity, it is difficult to disengage from the groove of the screw portion 1a, and the terminal 20 does not come off even if an inadvertent force is applied.

Further, since the tip end surface 23a of the bent piece 23 having a rattling function is in close contact with the peripheral surface of the stud bolt 1, the rattling of the terminal 20 is suppressed, and the reliability of the electrical connection state is improved. In addition, the reliability of the fixed state of the terminal 20 can be improved, and unnecessary rattling noise can be prevented.
In addition, the bending piece 23 and the locking claw 31 as the rattling presser
Since they are opposed to each other, the engagement state of the locking claw 31 becomes reliable, and the terminal 20 can be more reliably prevented from coming off.

Further, since the bent piece 23 is provided, the portion of the split 22 is reinforced, so that the position shift and deformation of the portion can be prevented, and the management of parts before fitting to the stud bolt 1 can be prevented. It is also possible to prevent the cylindrical body 21 from being crushed. Further, since the bent piece 23 constitutes the rattle holder, it is not necessary to form a separate rattle holder, and the rattle holder having sufficient strength can be easily formed.

On the other hand, when the terminal 20 is removed from the stud bolt 1 for maintenance or the like, the portion of the cylindrical body 21 having the elastic piece 27 is pinched and pressed as shown by the arrow in FIG. Then, as the elastic piece 27 bends,
The cylindrical body 21 is crushed and deformed, and the portion with the split 22 is deformed so as to bulge outward. Then, as a result, the flat portion 28
And the front end surface 23a of the bent piece 23 is opened, so that the locking claw 31 can be removed from the groove of the screw portion 1a. Therefore, the terminal 20 can be easily removed by lifting the cylindrical body 21 in that state.

In this case, the flat portion 28 having the locking claws 31 has a high rigidity, but the other portions have a low rigidity, so that the portion to which the force is applied can be easily identified, and a small force can be applied without difficulty. It can be removed.

As described above, according to the electric wire connecting terminal 20, the terminal 20 can be fixed to the stud bolt 1 only by fitting the cylindrical body 21 into the stud bolt 1, and a reliable electric connection state can be obtained. it can. In addition, the cylindrical body 21

Therefore, no special tool is required for mounting and dismounting, no working space is required for the tool, and the work can be performed easily. Moreover, at the time of fixing, since the locking claw 31 surely engages with the groove of the screw portion 1a, there is no possibility of coming off.

In the above embodiment, the locking claw 31 is provided on the side of the flat portion 28 having high rigidity, but the position of the locking claw is not limited to the above example.

An electric wire connecting terminal 40 of another embodiment shown in FIG.
Then, the locking claw 41 is provided so as to project from the upper end of the front end surface 23 a of the bent piece 23. Since the other structure is exactly the same as that of the previous embodiment, the same elements are designated by the same reference numerals and the description thereof will be omitted.

In the wire connection terminal 40 of this embodiment, the locking claw 41 is provided on the side opposite to the flat portion 28 side where the rigidity is increased, so that when the terminal 40 is removed, a small force is applied to the cylindrical body. While the peripheral wall of 21 is deformed, the locking claw 41 can be removed from the groove of the screw portion 1a.
The terminal 40 can be removed from the stud bolt 1 with a smaller force.

On the other hand, the bent piece 2 at the position of the split 22.
Since the locking claw 41 is provided on the tip end surface 23a of the rattling presser constituted by 3, the rattling presser and the locking claw 41 are continuous with each other, and at the time of mounting, locking the screw part 1a with respect to the groove. The engagement state of the claws 41 is stable, and reliable retention is achieved.
