Cable joint that can effectively prevent looseness

The invention relates to the connection technology of two cable wires, in particular to a cable connector which can effectively prevent looseness.

There are many techniques for connecting two cables. The applicant of this case also proposed the Republic of China M475538 patent, which mainly uses the relationship of threaded screw to borrow two tubes (inner tube and outer tube). It is connected by a sleeve and a pressing sleeve, and has the effect of lifting and reinforcing the fixed pipe body. In the practical application, the structure can also be applied to the fixing of the cable connection, as long as the outer tube and the inner tube are replaced with cables.

However, in practice, the aforementioned conventional techniques are applied to the cable, and there is still room for improvement. Since the sleeve and the outer tube are screwed together, when applied to a cable that requires motion (for example, an endoscope cable), the sleeve may be subjected to an external force after being used for a period of time in a combined state. However, there is a problem that the outer tube is rotated, and thus looseness may occur. After the loose condition is more serious, the outer tube may be further removed to cause the connection state to be disconnected.

In the first embodiment, the second fixing member 41 has a second fixing portion 42 , and the second fixing portion 42 provides an effect of fixing the second cable 92 . The second fixing portion 42 is provided. Can be a pin or thread, the designer can choose. In addition, in practice, the second fixing member 41 and the second joint 31 are screwed together.

The mating nut 51 is movably sleeved on the second joint 31. The mating nut 51 has a thread 52 at one end thereof, and is screwed to the mating thread 12 of the first joint 11, and the other end of the mating nut 51 There is an abutment edge 54.

The lock ring 61 has a thread 67 and a bevel 64 is provided on the outer surface.

The outer surface of one of the second joint 31 or the second fixing member 41 is provided with a locking thread 47. The locking ring 61 is screwed to the locking thread 47 by its thread 67, and The ramp 64 abuts against the abutment edge 54 of the mating nut 51. In the first embodiment, the locking thread 47 is fastened to the second fixing member 41, and the pitch of the locking thread 47 is equal to the pitch of the mating thread 12.

Wherein, the butt thread 12 is opposite to the thread of the lock thread 47.

In the first embodiment, the outer surface of the second joint 31 is provided with a stopping portion 38. The inner edge of the mating nut 51 is provided with a flange 58 which is annular and located in the block. Between the locking portion 38 and the locking ring 61, and the outer diameter of the locking ring 61 is larger than the inner diameter of the flange 58; the butting nut 51 can be abutted against the stopping portion by the flange 58 38.

The architecture of the first embodiment has been described above, and the assembled state of the first embodiment will be described next.

Referring to FIG. 4, before the combination, the first joint 11, the first fixing member 21 and the first cable 91 are assembled, and the second joint 31 and the second fixing member 41 are assembled. The docking screw The cap 51, the lock ring 61, and the second cable 92 are assembled. At this time, the locking ring 61 is screwed onto the second fixing member 41. Since the flange 58 is located between the blocking portion 38 and the locking ring 61, the mating nut 51 does not The second joint 31 is dropped.

As shown in FIG. 5, in the combination, the first joint 11 is butted against the second joint 31, and the plurality of terminal blocks 15 are inserted into the plurality of terminals 35 to form an electrical connection relationship, and then moved. The mating nut 51 has its thread 52 screwed to the mating thread 12 of the first joint 11 and tightens the mating nut 51 until the flange 58 abuts the stop portion 38 of the second joint 31 . Therefore, the second joint 31 is pushed against the first joint 11 , and the mating relationship between the first joint 11 and the second joint 31 is clamped by the butting nut 51 .

As shown in FIG. 6 , finally, the locking ring 61 is rotated to move the inclined surface 64 toward the abutting edge 54 of the mating nut 51 until the inclined surface 64 abuts against the abutting edge 54 , thereby completing the assembly. It can be used normally.

In the assembled state, since the locking thread 47 is opposite to the threading direction of the mating thread 12, the direction of rotation of the locking ring 61 is opposite to the tightening direction of the mating nut 51. In the state in which the assembly is completed, since the inclined surface 64 abuts against the abutting edge 54, the mating nut 51 and the lock ring 61 interfere with each other in operation. With this interference relationship, when the docking nut 51 is subjected to an external force and is intended to rotate in the loosening direction, that is, the locking ring 61 is interfered to rotate in the tightening direction thereof, the fixed lock ring 61 cannot be rotated because it is already tightened. Rotating again, that is, the interference nut can be prevented from rotating in the loosening direction by this interference relationship; conversely, if the fixed lock ring 61 is subjected to an external force smaller than the interference force of the interference relationship and is to be rotated in the loosening direction It is also blocked by the butt nut 51 by this interference relationship without rotating in the loosening direction. Thereby, it is possible to effectively connect the two cables and lock the connection state to prevent the loosening effect.

Referring to FIG. 7, a cable connector 70 for effectively preventing looseness according to a second preferred embodiment of the present invention is mainly similar to the first embodiment disclosed above, except that: The fixing thread 47' is not disposed on the second fixing member, but is disposed on the second joint 31', whereby the locking ring 61' is screwed to the second joint 31'. Thread 47'.

The foregoing structure is mainly for explaining that the position where the fixing thread 47' and the fixing ring 61' are disposed is not limited to the position of the first embodiment.

The remaining structure of the second embodiment and the achievable effects are the same as those of the first embodiment, and will not be further described.

It should be noted that in the foregoing two embodiments, the pitch of the locking thread 47 is equal to the pitch of the mating thread 12, however, the pitch of the locking thread 47 may be changed to be smaller than the The pitch of the butt threads 12. Such a change can cause the movement amount of the fixed lock ring 61 to rotate by a predetermined angle to be smaller than the movement amount of the same angle of the butt nut 51, and further cause the lock ring 61 to pin the rotation of the butt nut 51. The effect is to increase the effect of preventing loosening. Since the manner in which the thread pitch is set is well understood and is not understood in the drawings.
