Description

[Detailed description of the invention] The present invention relates to the invention of a power transmission line connecting device, and provides a connection mechanism that can be used for power transmission lines of different thicknesses or diameters such as a coaxial cable and a ribbon feeder or a spectacle feeder, and furthermore, The object of the present invention is to provide a mechanism that enables simple and accurate connection and disconnection operations without the need for complicated operations using special tools.

It is well known that devices such as television receivers use coaxial cables and parallel power transmission lines called ribbon feeders and spectacle feeders. Conventionally, parallel ribbon feeders or spectacle feeders were generally used. However, in recent years, coaxial cables are increasingly being used. However, because these power transmission lines have completely different thicknesses or diameters, conventionally it has been common to use each connection mechanism interchangeably, and for this purpose, multiple types of connection mechanisms are prepared, Moreover, it is clear that a considerable amount of man-hour is required for its replacement. In other words, in the case of this coaxial cable, it is natural that the core wire and the outer conductor wire should be connected separately, but special work is required after stripping the sheath and insulation layer. The numerous fine wire groups of the sheathed conductor exposed by peeling off the layers are folded back in an almost orderly manner and inserted between the caulking parts of the socket grounding fitting and the caulking fitting connected to the socket, or between the fitting and the grounding fitting in the saddle. However, it is necessary to further peel off the intermediate insulating layer exposed by folding back the jacket conductor as described above and screw the protruding core wire to another contact fitting. Fastening is done in multiple stages in the axial direction of the cable, which requires a considerable amount of work and requires a turning operation using a special screw turning tool. In the case of the above-mentioned ribbon feeder or spectacle feeder, the coaxial cable can be connected by simply peeling off the insulation coating, but in this case, conductors are arranged on both sides, so the cable has a certain width. In addition, it is necessary to perform the screw fastening operation twice, which is different from the multiple stages in the axial direction as described above, and furthermore, even if the same pressing and tightening is performed, the sheathed conductor part and the feeder are Because the thickness of the conductor is significantly different from that of the conductor, and coaxial cables with different diameters are in practical use, it is difficult to connect them with the same connection device, If an attempt is made to connect the two, the configuration and operation will inevitably become extremely complicated and redundant.

The present invention was devised after repeated studies in view of the above-mentioned circumstances. A pivot fitting is attached to an insulating base body, and a semicircular shape is attached to the pivot seat formed on the pivot fitting. Pivot holes are connected and arranged in multiple stages,
Insertion/removal openings are formed in these pivot holes, and a locking protrusion is formed on one side of the insertion/removal opening, and a semicircular turn that is fitted into the pivot hole is formed at the base end of the locking part body. The power supply line connecting device is characterized in that a moving shaft is provided, and a push-in portion is provided in the engaging portion body for a terminal fitting provided in the base portion body.

That is, a specific embodiment of the present invention as shown in the accompanying drawings will be described. A pivot fitting is attached to an insulating base member 10 such as a case of a receiving or image receiving mechanism or a wiring board provided therein. 1, and the shaft portion 21 formed at the proximal end of the insulating engaging portion body 2 is rotatably supported and continuously supported by the pivot seats 11, 11 formed on the pivot fitting 1,
Terminal fittings 3 and 4 are arranged on the base body 10 separately from the pivot fitting 1, and the mounting side of the pivot fitting 1 is used as the insertion port 12 for the power supply line as described above,
A terminal fitting 3,
These terminal fittings 3, 4 are each formed in a U shape, and such terminal fittings 3, 4 are attached one after another.
By pushing the push-in portions 23, 23 and 24 of the locking member 2 into the locking member 2, the core wire or the conductive wire of the feeder is locked as shown in FIGS. 2 to 4. Further, the base body 10 is provided with a guide 13 for guiding the conductor of the feeder to the terminal fitting 3 portion as described above, and a guide 14 for guiding the core wire of the coaxial cable to the terminal fitting 4 portion. These guides 13 and 14 are connected to the base body 10.
It may be formed integrally with the material, or may be formed separately and fixed with an adhesive or the like. Further, the base body 10 is provided with a hole-shaped engaging portion 1.
5 and 15 are provided oppositely on both sides of the terminal fitting 4, and the locking portions 25 and 25 of the locking portion body 2 are made to face these engaging portions 15, and the push-in portion 23 as described above is , 24 in a pressed and bent state as shown in FIGS.
5a is latched and locked to the engaging part 15,
In order to elastically achieve such locking, a notch 26 as shown in FIG. 5 is provided in the locking portion 25 of the locking portion body 2.

As shown in FIGS. 5 and 1, a plurality of guide grooves 22 are formed in series on the insertion port 12 side of the engaging body 2 from the tail end surface to the bottom surface. These guide grooves 22 are on the bottom surface.
As clearly shown in FIGS. 2 to 4, the recessed groove 22c is formed across the guide groove 22, and the locking protrusion 1d of the pivot fitting 1 is formed on the lower surface of the guide groove 22. 1d is faced.

In the present invention, the above-mentioned pivot structure between the engaging part body 2 and the pivot fitting 1 facilitates the assembly operation,
Moreover, special measures have been taken to quickly respond to changes in the thickness or thickness of the conducting wires to be connected.
That is, the pivot seats 11, 11 have pivot holes 11a, 1.
1a are formed in multiple stages, and these pivot holes 11a,
All 11a are downward semicircular,
Furthermore, an insertion/removal port 11b is opened to the upper side of the pivot seat 11 on one side, and a claw-shaped engaging protrusion 11c is provided on the upper side of the insertion/removal port 11b. A rotating shaft 21 protruding from the proximal end of the rotary shaft 21 has a downward semicircular shape as shown in the figure. When attaching the lid and attaching the engaging part body 2 to the pivot fitting 1, as shown by the imaginary line in FIG. The rotation axis 21 is tilted as shown in FIG.
The engaging protrusion 11 is inserted into the insertion/removal port 11b.
This means that it can be dropped without getting caught in c.
After the rotation shaft 21 is dropped into the engaging protrusion 11c in this way, if the engaging part body 2 is made vertical, it can be freely fitted to any position in the pivot holes 11a, 11a. Can be done. That is, Figure 1 or Figure 8.
As shown in the figure, the power supply line to be connected is inserted into the insertion port 1 with the engaging part body 3 tilted at an angle of about 70 to 80 degrees.
2, but during this insertion, the guide groove 22 as described above guides the body properly and allows for smooth insertion.Then, the engaging body 2 is laid down as shown in FIGS. 2 to 4. Then, the power supply line is held and connected to the terminal fitting 3 or 4 and the pivot fitting 1. In this case, the parallel power supply line is shown as B in FIGS. 2 to 4, respectively. Pivot connection can be made by selecting either of the pivot holes 11a, 11a in order to immediately respond to changes in the thickness or thickness of the ribbon feeder 6, the spectacle feeder 7, or the coaxial cable 8, which is a coaxial type power transmission line. In either case, a desirable gripping connection can be achieved. In response to such changes in the diameter of the power supply line, the locking steps 25a of the locking portion 25 can be multi-staged as shown in FIGS. 6 and 7. Furthermore, when the base body 10 as described above is a case itself, the mechanism of the present invention is disposed adjacent to the case side wall 10b, and even when the base body 10 is formed separately from the case itself, it is a case itself. As shown in the figure, it is attached in contact with the side wall 10b, and the power supply line insertion opening 10b' is formed in the case side wall 10b.
By fixing the separately formed base body 10 close to the case side wall 10b as described above, the rotation range of the engaging body 2 is limited to 90 degrees or less, as shown by the imaginary line in FIG. Since rotation of more than 100 degrees as shown cannot be obtained, the rotation shaft 21 once glued is caught on the engagement protrusion 11c and cannot be removed, and the upper pivot hole 11a is only half the extent. In this embodiment in which no such structure is formed, the rotation shaft 21 can be freely moved to any one of the multi-stage pivot holes 11a, 11a.

According to the present invention as described above, as shown in FIGS. 2 to 4, the ribbon feeder 6, the spectacle feeder 7, and the coaxial cable 8 can be quickly adapted to changes in thickness and thickness, and the same connection can be made. A device that can be connected in a mechanism,
There is no need to replace each connection mechanism depending on the type of power supply line, and the connection operation is as simple as simply raising and lowering the anchoring body 2, which has a great practical effect. It is an idea.
