Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable bis that connects a plurality of operating members, such as a control cable and its operating lever.

For example, a clevis 1 as shown in FIGS. 1 and 2 is used to connect a clutch pedal and a control cable of an automobile.

The clevis 1 is formed into a U-shape with a flat surface, and has a connecting pin 3 fixed to a tip opening 2.

The control cable 5 is constructed by inserting the end of the inner wire 7 inserted into the outer tube 6 into the mounting hole 4 formed at the rear end of the clevis 1, and fixing the stopper 8 to the end by caulking it to the rear end of the clevis 1. The connecting pin 3 of the rear end opening 2 of the clevis 1 is connected to the clutch pedal arm by engaging with an engaging portion provided on the overseas clutch pedal arm.

By the way, when connecting the control cable 5 and the clutch pedal arm 9, the control cable 5 and the clutch pedal arm 9 must be connected to the engine compartment 11 of the vehicle, which is separated by the dash panel 10, as shown in FIGS. 12, the control cable 5 is inserted from the engine room 11 side into the through hole 13 formed in the dash panel 10, and the connecting pin 3 of the clevis 1 at the tip is connected to the clutch pedal arm in the blind spot of the installer. 9, for example, a hook portion 9a formed at the end of the arm.

However, the opening width l of the tip opening 2 of the clevis 1 cannot be made unnecessarily larger than the plate thickness t of the hook part 9a, in order to prevent looseness between the clevis 1 and the hook part 9a and to ensure the strength of the pin 3. Since the thickness is slightly larger than the plate thickness t, it is extremely difficult to perform the connection work in blind spots as described above, which significantly impairs work efficiency.

In FIG. 3, reference numeral 14 indicates a lock nut which also serves as an adjuster, and reference numeral 15 indicates a sealing grommet interposed between the outer tube 6 and the through hole 13.

In view of this conventional situation, the present invention widens the opening edge at the tip of the clevis to prevent rattling and ensure pin strength without changing the effective opening width of the clevis, making it possible to easily perform connection work. It is something.

That is, in the present invention, as illustrated in FIG. 5, the tip opening edge 2a of the clevis 1 is curved outward and expanded without changing the effective opening width l of the fixing portion of the connecting pin 3. .

Therefore, when this clevis 1 is used for connecting the control cable 5 as the first actuating member and the clutch pedal arm 9 as the second actuating member as in the conventional case, for example, the inner wire 7 of the control cable 5 is attached to the rear end of the clevis 1 in advance. When connecting the clevis 1 to the hook part 9a at the end of the pedal arm 9 from the engine compartment 11 side through the through hole 13 of the dash panel 10, the tip opening edge 2a of the clevis 1 is connected as described above. Since the clevis opening 2 is widened, the clevis opening 2 can easily fit into the hook part 9a, and the connection work can be easily performed in a blind spot position.

In the connected state, the effective opening width l of the clevis, taking into account the plate thickness t of the hook part 9a, is not changed in any way, so there is no looseness between the clevis 1 and the hook part 9a, and the connection pin 3 It can ensure strength,
Although the structure is simple, its practical effects are great.

In addition, the clevis of this invention is compatible with the aforementioned control cable,
The same effect as described above can be achieved by using not only the connection of clutch pedal arms but also the connection of a plurality of working members.
