Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable joint device which is interposed between a pair of cables having an outer cable and an inner cable which is movably inserted in the outer cable and which connects the two cables.

[0002]

2. Description of the Related Art A cable joint device of this type includes a device for connecting a cable connected to the body side of an automobile and a cable connected to the trunk room side, for example. The outer cables of the pair of cables are fixed to the joint case while facing each other, and the inner cables of the pair of cables are connected to each other in the joint case.

Some cable joint devices having such a structure do not have a mechanism for adjusting the distance between the inner cables when they are extended due to use, and in such a case, the tension of the inner cables must be adjusted. Had to be adjusted outside the joint case, which was extremely inconvenient.

Some cable joint devices are equipped with an adjusting mechanism. In that case, the male screw portion provided on the outer cable of the cable is screwed into the female screw portion on the joint case side, and the screwing state is set. After changing the inner cable tension, the outer cable was fixed to the joint case with a fixing nut. Therefore, even if the bending angle and the tension of the cable are adjusted, the position of the outer cable with respect to the joint case is changed and the tension of the cable is changed if the fixing nut is loosened due to play or the like during use.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to illustrated embodiments. As shown in FIG. 1, the cable joint device 11 to which the present invention is applied includes outer cables 16 a and 17 a.
a and a pair of cables 16 and 17 having inner cables 16c and 17c movably inserted into the outer cables 16a and 17a, respectively.
It has a joint case 12 for connecting 6 and 17, which is to be fixed to the body of an automobile or the like. This cable joint device 12 has two ends in its longitudinal direction.
Engagement notches 12a, 12a for separating and fixing the outer cables 16a, 17a of the pair of cables 16, 17 to be connected to each other are formed. The outer cable 16 is provided in each of the engagement notches 12a and 12a.
The engaging groove portions 16b and 17b of a and 17a are engaged and fixed.

In the joint case 12, the cable 1
A movable end member 19 fixed to the tip of the inner cable 16c of No. 6 and supported so as to be movable in the moving direction of the inner cable 16c is slidably positioned. As shown in FIG. 2, the movable end member 19 is formed in a box shape having a plurality of engaging tooth portions (adjustment and fixing means) 21 inside. Each of the plurality of engaging tooth portions 21 is
Inserting an adjusting plate (end member, adjusting fixing means) 20 from above between the engaging teeth 21 and 21 formed on the inner surfaces of both sides and the bottom of the joint case 19. The plate 2
0 can be engaged without a gap and can be fixed without rattling. Further, a lid 15 is rotatably provided on the joint case 12 via a hinge 13, and when the lid 15 is rotated and closed, the cables 16 and 17 are respectively attached to the outer cables 16a and 17a. Of the movable notch 12a and the movable end member 19 from the joint case 12 are prevented from coming off. In addition, 15b in FIG. 1 is a holding groove portion formed at one end portion of the lid body 15 for engaging with the engaging groove portion 17e of the outer cable 17a and firmly pressing it.

The adjusting plate 20 is formed in a rectangular shape, and the front end of the inner cable 17c of the cable 17 is inserted into the central portion of the adjusting plate 20 from above and the end 17d of the inner cable 17c is engaged to prevent the adjustment plate 20 from coming off. Engagement notch 20
a.

According to the cable joint device 11 having the above structure, the cable fixing work can be performed as follows. First, the movable end member 19 is attached to the tip.
The outer cable 16a in a fixed state is fixed by engaging the engagement groove portion 16b with the engagement notch 12a of the joint case 12. In addition, the cable 17
The engagement groove portion 17b at the tip is fixed to the case 12 by engaging with the engagement notch 12a of the joint case 12, and further, the adjustment plate 20 in a state in which the tip of the inner cable 17c is sandwiched and the end 17d is prevented from coming off.
The inner cables 16 of the cables 16 and 17 respectively.
While watching the tension of c and 17c, the appropriate engaging tooth portion 21
Engage and adjust. The adjustment allowance of the adjustment plate 20 during this adjustment work is shown by a in FIG.

As a result, the two cables 16 and 17 are appropriately connected to the inner cables 16c and 17c, respectively, by applying proper tension thereto. As described above, by appropriately changing the engaging position of the adjusting plate 20 with respect to the movable end member 19, the connection state (tension) of the pair of cables 16 and 17 can be adjusted very easily. Further, since the adjusting plate 20 firmly engages with the engaging tooth portion 21 in the state in which the inner cable 17c is engaged, the state change after adjustment is unlikely to occur.

[0013]

As described above, according to the present invention, a joint case that separates and fixes the outer cables of a pair of cables, and the inner case is movably supported in the joint case. A movable end member fixed to either one of the pair of inner cables, an end member coupled to the other of the pair of inner cables, and this end member is positioned in the moving direction of the inner cable with respect to the movable end member. Since the position adjusting fixing means for adjusting and fixing is provided, by appropriately changing the engaging position of the end member with respect to the movable end member, the connection state of the pair of cables can be adjusted very easily. It is possible to provide a cable joint device having a structure that does not easily cause a state change.
