DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in FIGS.

In FIG. 1 and FIG. 2, reference numeral 20 denotes a cable mounting terminal according to the present embodiment.
Reference numeral 0 denotes a structure that is fitted with a single touch to a mounting plate 21 formed on a motion transmission control assembly provided in a vehicle body or the like. That is, the mounting plate 21 is formed with a U-shaped notch 22 for fitting a cable mounting terminal, and a locking hole 23 for preventing the cable mounting terminal fitted in the notch 22 from coming off.

The structure of the cable mounting terminal 20 will now be described. The cable mounting terminal 20 has a cylindrical main body 19 having a cable insertion hole 24 for inserting and fixing an outer shaft of a power transmission cable (not shown). The main body is formed of resin. The U-shaped groove 25 into which the edge 22A of the U-shaped notch 22 formed in the mounting plate 21 is fitted from at least the right and left sides, which is the outer periphery of the cable mounting terminal 20, to the bottom surface. A pair of wall surfaces 2 spaced in the axial direction of
6 and 27 are formed.

Reference numeral 28 projects from the outer peripheral bottom surface of the cable attachment terminal 20 in the radial direction thereof. The U groove 25 of the cable attachment terminal 20 is completely fitted into the U-shaped notch 22 of the attachment plate 21. The locking claw is locked with the locking hole 23 when the locking claw 28 has a front shape obliquely upward from the lower end and toward the U groove 25 as shown in FIG. It is formed in a substantially R-shape that protrudes, and the entire locking claw piece has a flexible elasticity in the U groove 25 direction.

Reference numeral 29 designates a protection wall for the locking claw, which is formed upright at a position corresponding to the U-shaped groove 25 on the left side surface of the locking claw 28, and a central portion of the protection wall 29. In
An insertion groove 30 for a tool used to release the locking between the locking claw piece 28 and the locking hole 23 is formed. A protective wall 3 is provided at a position corresponding to the left side surface of the locking claw 28.
1 are formed upright, and both of the protective walls 29 and 31 are formed.
Thus, the locking claw piece 28 is protected so as not to receive an external force particularly in the axial direction of the cylindrical body.

One wall surface 2 forming the U groove 25
6, a rib 32 parallel to the fitting direction of the mounting plate to be fitted into the U groove 25 is integrally formed.
Are provided with two pressing pieces 33 protruding into the U-groove 25 and being urged in the direction of the wall surface 26 at symmetrical positions sandwiching the axis of the cylindrical body.

Reference numeral 34 shown in the drawing denotes a reinforcing rib formed to increase the rigidity of the cable attachment terminal 20.

The above is the configuration of the present embodiment. Next, the operation will be described. The cable mounting terminal 20 having the above configuration to which the power transmission cable is connected is attached to the mounting plate 21.
In order to mount the cable mounting terminal 20, the edge 22A of the notch 22 formed in the mounting plate 21 is fitted into the U groove 25 formed in the cable mounting terminal 20, and the cable mounting terminal 20 is When the cable mounting terminal 20 is completely pushed in from above the notch 22 of the mounting plate 21 and the cable mounting terminal 20 is completely pressed, the locking claw piece 28 provided on the cable mounting terminal 20 is locked in the locking hole 23 of the mounting plate 21. Then, the cable attachment terminal 20 is fitted to the attachment plate 21 in a one-touch manner in a retaining state.

In this embodiment, when the mounting plate 21 is fitted into the U-shaped groove 25 of the cable mounting terminal 20, a rib 32 extending in the fitting direction is formed on the wall surface 26 which comes into sliding contact with the mounting plate 21. Therefore, the sliding contact resistance between the cable mounting terminal 20 and the mounting plate 21 is reduced, so that the cable mounting terminal 20 is notched 2
2 can be smoothly fitted, and the workability of fitting the cable mounting terminal 20 to the mounting plate 21 is improved.

On the wall surface 27 forming the U groove 25, a flexible elastic pressing piece 33 projecting toward the U groove 25 is provided.
Is formed, even if the thickness of the mounting plate 21 fitted into the U-groove 25 varies due to the elasticity of the pressing piece 33, the pressing piece 33 remains on the plate surface of the mounting plate 21. Therefore, there is no play between the mounting plate and the cable mounting terminal 20, and a mounting structure of the cable mounting terminal excellent in mounting reliability and mounting accuracy can be provided.

Further, since the shape of the locking claw 28 provided on the cable attachment terminal 20 is formed substantially in the shape of a front, the distance from the base end to the tip of the locking claw 28 is increased. Since it is ensured, the amount of elastic deformation of the locking claw piece 28 in the locking direction can be set large,
As a result, it is possible to increase the reliability of the locking between the locking claw pieces 28 and the locking holes 23. Further, since the locking end of the locking claw 28 is formed in a L-shape in the direction opposite to the fitting direction of the cable attachment terminal, the locking claw 28 is locked with the locking hole 23. After that, when an unreasonable external force is applied to the cable mounting terminal 20 in the direction of detaching the cable mounting terminal 20 from the mounting plate 21, the locking end of the locking claw 28 becomes a stress biting into the locking hole 23. In addition, the reliability of the locking between the cable mounting terminal 20 and the mounting plate is enhanced.

Further, since both the protection walls 29 and 31 are provided in the axial direction of the cable attachment terminal 20 so as to sandwich the locking claw piece 28 therebetween, the cable attachment terminal can be used, for example, during handling handling or When the cable attaching terminal is assembled, even if an impact force or the like is received from another object in the axial direction, the locking claw 28 is protected by the two protective walls 29 and 31. As a result, a cable mounting terminal having excellent durability can be provided.

Since a tool insertion groove is formed in the one protection wall 29, a tool such as a screwdriver is inserted into the locking claw piece 28 by using the tool insertion groove 30. This facilitates the release of the locking between the locking claw pieces 28 and the locking holes 23 by the tool guided in the tool insertion groove 30, and allows the cable mounting terminal 20 to be removed from the mounting plate 21 when necessary. The removal workability for removal is also good.

[0027]

As described above, according to the first aspect of the present invention, the locking claw 28 provided on the cable attachment terminal is protected from the impact by the protection plate, so that the cable When handling the mounting terminal, the locking claw piece 28 does not receive an impact force, and the cable mounting terminal is excellent in durability and structural reliability.
Also, by forming the locking claw pieces 28 in a letter-like shape,
The locking action with the mounting plate is reliable, and the mounting reliability is high. Further, the provision of the ribs 32 has an operational effect that the workability of fitting the cable mounting terminal to the mounting plate is greatly improved.

According to the second aspect of the present invention, by the action of the pressing piece 33, the cable mounting terminal can be mounted on the mounting plate having a variation in plate thickness without play. According to the third aspect of the present invention, the cable mounting terminal once mounted on the mounting plate can be easily removed from the mounting plate as needed.
