Description

[Detailed description of the invention] The present invention relates to the invention of a power transmission line connecting device, and relates to a connection mechanism that can connect a coaxial cable and a parallel type power transmission line such as a ribbon feeder or a spectacle feeder, and the connection or disconnection operation thereof. The purpose of this invention is to provide a mechanism that allows simple and accurate connection without requiring complicated operations using special tools.

It is well known that television receivers use coaxial cables and parallel power transmission lines called ribbon feeders and spectacle feeders. It was used, but
In recent years, coaxial cables are increasingly being used. However, since these power supply lines have completely different configurations, it has conventionally been common to use them with respective connection mechanisms. However, in the case of coaxial cables, it is natural that the core wire and the outer conductor should be connected separately, and special work is required after stripping the sheath and insulation layer. The countless fine wires of the sheathed conductor exposed by peeling off the wire are placed in a nearly orderly manner, and the screws are inserted between the caulking part of the socket grounding metal fitting and the caulking metal fitting connected to it, or between the metal fitting and the grounding metal fitting in the saddle. However, it is necessary to process the sheathed conductor as described above, peel off the exposed intermediate insulating layer, and screw the protruding core wire to another contact fitting. There are multiple stages in the axial direction, and the machining process requires a considerable amount of time and requires a turning operation using a special screw turning tool. In the case of the above-mentioned ribbon feeder or spectacle feeder for such a coaxial cable, it is sufficient to simply peel off the insulation coating and connect it.
In this case, conductors are arranged on both sides, so it has a certain width, and it is necessary to perform screw fastening operations twice, which is different from the multi-stage arrangement in the axial direction as described above. It is. Furthermore, even if the same pressure and tightening is performed, it is difficult to connect the sheathed conductive wire portion and the feeder conductive wire portion with the same connecting device because the thicknesses of the sheathed conductive wire portion and the feeder conductive wire portion are significantly different. If they were to be connected using the same connection part, the configuration and operation would be extremely complicated and redundant, and in the case of, for example, Japanese Utility Model Application Publication No. 56-28182, a screw turning tool would be required, and the means for tightening would be considerable. It has to be something that depends on.

The present invention was devised after repeated studies in view of the above-mentioned circumstances, and the specific embodiment thereof is shown in the attached drawings. In a device for connecting parallel conductors 6, 7 or coaxial conductors 8 to a base body 10 made of an insulator such as a wiring board, a pivot fitting 1 is attached to the base body 10, and the pivot fitting 1 is attached to the base body 10. A shaft portion 21 formed at the proximal end portion of the engaging portion body 2 made of an insulating material is rotatably supported and continuously supported by the pivot seats 11, 11 formed in the
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,

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 insertion 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 so that the locking steps 25a of the engaging portions 25, 25 are locked to the engaging portion 15 in the pressed and bent state as shown in FIGS. 2 to 4. In order to provide elasticity, 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. As shown in FIGS. 2 to 4, recessed grooves 22c are formed on the lower surface of the guide grooves 22 so as to cross these guide grooves 22. The locking protrusions 1d, 1d of the fitting 1 are exposed. Figure 4A
In this case, the insulation coating of the coaxial cable 8 is partially peeled off to expose the outer conductor 8c, and in this state, the coaxial cable 8 is inserted onto the pivot fitting 1 in the same manner as in FIGS. By rotating and lowering the core wire around its shaft portion 21, the core wire is pressed and engaged with the terminal fitting 3 at the push-in portion 23, and the outer conductor 8c is connected to the ground wire connection portion by the end portion 22a of the guide groove 22. Locking protrusions 1d, 1d of pivot fitting 1 having 1e

In this embodiment, the above-mentioned pivoting structure between the engaging part body 2 and the pivot fitting 1 has special features to facilitate the assembly operation and to quickly adapt to the thickness of the conductor to be connected. being done.
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.

The power supply line is held and connected to the terminal fitting 3 or 4 and the pivot fitting 1 by laying it down. It is possible to make a pivot connection by selecting either the pivot hole 11a or 11a in accordance with the thickness of the ribbon feeder 6, spectacle feeder 7 belonging to the power transmission line, or the coaxial cable 8 which is the coaxial type power transmission line. A preferable gripping connection can also be made in this case. 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. Note that 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. side wall 10b
