Description

[Detailed description of the invention] This invention is a technology that can be used in the terminal structure of electronic devices, etc., and the purpose is to provide a splint that can quickly pinch the core wires of electric wires, cables, etc. It is something.

Embodiments of the present application will be described below with reference to the drawings.

1 is a printed circuit board, 1a is a metal foil, and 1b is a portion made of an insulating material.

Reference numeral 2 denotes a through hole into which the tip 9a of the sandwich plate 9 is inserted.

3 is a square hole into which the tongue piece 8 is inserted.

4 is the saddle body, which has an A-shaped cross section.

Reference numeral 5 denotes seat plates on both sides of the saddle, which have through holes 22 for inserting screws.

6 is a through hole 22 in the seat plate and a through hole 2 provided in the printed circuit board.
3 and is threaded into the nut 6'.

In short, it is a screw for attaching a seat plate to a printed circuit board.

Next, 7 is the terminal body placed on the printed circuit board 1,
It has a mouth-shaped cross section and is made of a conductor.

8 is a tongue protruding from the terminal body, which is inserted into the square hole 3 provided on the printed circuit board 1, and by twisting and bending the tip, the terminal body 7 is fixed to the printed circuit board. belongs to.

These tongue pieces are provided on both sides of the terminal body 7, and are inserted into square holes 3 provided in the printed circuit board, respectively, to help fix the terminal body 7.

Reference numeral 9 denotes a sandwich plate located within the terminal body, and a screw hole 10 is bored in the sandwich plate itself.

Further, one end 9a thereof is inserted through the through hole 2 of the printed circuit board described above.

The plate itself is made of a conductive material, and the tip of the plate extends like an elephant's trunk and is inserted into a hole, making the plate look like the one shown in Figure 2. The length should be such that it will not slip out of the hole even when placed in the correct position.

10 is a screw hole drilled in the sandwich plate, and is a female screw hole like a nut.

A screw 11 is loosely inserted into a hole 7a provided directly above the terminal body, and is screwed into a screw hole 10 of the sandwich plate, and its tip is inserted into the printed circuit board 1. It is inserted into the through hole 27 in a loose manner.

Next, although the printed circuit board can be used horizontally, it is generally arranged upright in a housing 12 as shown in FIG.

A mounting portion 13 protruding from the back surface of the housing 12 is a mounting portion for the mast 14, and is comprised of a tightening bolt 23, a presser 24, and a nut 25, and is fixed in a well-known manner.

Note that the reference numeral 12b is a sliding type lid of a well-known structure that can be moved in the vertical direction.

12a indicates an electronic circuit provided in the space of the housing.

Since the members indicated by reference numerals 12 to 14, 23, 24, and 25 are well-known structures used in boosters and the like, detailed explanation thereof will be omitted.

In the above configuration, first, the power supply line 15 is pushed in the direction of the arrow 16 in the state shown in FIG.

In this case, when the power supply line rises, its core wire 15b hits the sandwich plate and pushes the sandwich plate in the direction of arrow 17.

If you push the feeder wire further in the direction of arrow 16, core wire 15b
is guided by the intermediate curved surface of the sandwich plate, and the sandwich plate 9 is further
While pushing it in seven directions, it is moved to the position 9' shown by the dashed line, and it easily fits between the receiving part 7b of the terminal body 7 and the sandwich plate 9.

Thereafter, when the screw 11 is rotated, the clamping plate moves in the direction of the arrow 18, and eventually the core wire is clamped in the state shown in FIG. 2.

Further, the saddle body 4 also tightens the braided portion 15a of the cable by tightening the screws 6, thereby electrically coupling the metal foil 1a and the saddle, and mechanically tightening and fixing the braid to the metal foil via the saddle.

Electrically, the core wire is connected to the terminal body, and the terminal body is connected to the tongue piece 8.
Electrical connection is achieved by soldering 26 to the metal foil 1a of the printed circuit board.

In particular, in the above configuration, in the state shown in FIG.
Although it is quite difficult to insert the b (sometimes the 15
(b may enter the space 20), but in the above embodiment, the presence of the elephant trunk-like pinching plate 9 allows the curved surface 9b to guide the core wire 15b, so the above-mentioned problem does not occur.

In the above embodiment, a coaxial cable is used as the feeder line, but if a feeder or the like is used as the feeder line, the core wire of the coaxial cable in the above example
5b indicates the core wire of either one of the feeders.

It can also be used as a terminal for general vinyl-coated wires.

As described above, the present invention has the advantage that since the terminal body has a bent-tipped sandwich plate, the core wire can be inserted very easily even in the state shown in FIG. 3.
