Description

[Detailed Description of the Invention] The present invention relates to a wire connector that can be used for electrical connections for printed circuit boards, mounting boards, and wrapping wiring by simply replacing terminals.

For example, in a terminal for an audio device to which an output cord to a speaker is connected, electrical connection modes between the terminal of the terminal and the audio device include those for a printed circuit board, for a mounting board, and for wrapping wiring.

However, in conventional terminals of this type, the terminal, main body, and other parts are molded for each connection mode, so there is a drawback that individual parts cannot be used for terminals with different connection modes.

Therefore, the cost of the product was inevitably high.

Therefore, the purpose of the present invention is to provide a wire connector that can be used for printed circuit boards, mounting boards, and wrapping wiring by simply replacing the terminals by making other components common except for the terminals. There is a particular thing.

Reference numeral 51 denotes an insulating wire pressing body rotatably held inside the container body 21.

This electric wire pressing body 51 has a shaft 52 which is rotatably held in the rotation groove 32 of the container body 21 on both sides of the lower end, and the electric wire W is clamped between the shafts 52 and the mount board terminals 41a and 41b in the middle. The conductive clamping pieces 53 are each provided with an operating portion 54 at the upper portion thereof which protrudes outward from the window hole 30 of the container body 21 .

The clamping piece 53 is assembled with its front portion facing the wire insertion hole 29 of the container body 21 and its rear end slightly protruding toward the rear surface of the wire pressing body 51.

The spring 55 inserted between the rear end of this clamping piece 53 and the spring receiving part 31 of the container body 21 allows the clamping piece 53 of the wire pressing body 51 to constantly hold the mounting board terminal with the shaft 52 as a fulcrum. 41a, 41a side is energized.

In the above configuration, first, the wire pressing body 51 is inserted into the inside of the container body 21 from the lower surface, its operating portion 54 is projected to the outside from the window hole 30, and the shaft 52 is housed in the rotation groove 32.

Next, the rear end of the clamping piece 53 of this wire pressing body 51 and the
After inserting the spring 55 between the spring receiver 31 and the spring receiver 31, the bent pieces 42a and 42b of the mounting board terminals 41a and 41b are inserted into the terminal storage groove 33 of the container body 21.

Then, when the two containers 21 temporarily assembled in this way are placed facing each other in the same direction from the back to each other, the respective locking claws 26 are engaged with the engagement grooves 25 of the opposing containers 21.

Next, when this object is inserted into the base body 1, the locking claws 24 on the front wall of each vessel body 21 are locked into the locking grooves 10 and 11 of the base body 1, and the vessels are assembled in parallel.

At this time, the flange pieces 23 of the vessel body 21 are fitted into the grooves 7 of the base body 1, respectively.

In addition, the terminal piece 45a of the mount board terminal 41a in the front row
are housed in the terminal insertion groove 8, and the rear mount board terminals 41a are housed in the guide groove 14 and the terminal insertion groove 9, respectively, and protrude forward.

After the assembly is completed according to the above procedure, the locking claws 4 of the base body 1 are used to perform the assembly.

In addition, when attaching this to the rear panel of the audio equipment, attach it so that the part of the body 21 is exposed to the outside from the inside of the rear panel, and use the mounting holes 6 and 22 to attach it. The rear panel and base 1 are screwed together.

Then, the flange piece 23 of the vessel body 21 is held between the rear panel and the base body 1, so that the vessel body 21 is completely fixed.

Next, when using the above for a printed circuit board, use the mounting board terminal 4 shown in FIGS. 4a and 4b above.
A printed circuit board terminal 41c shown in FIG. 5 is used in place of 1a and 41b.

This printed circuit board terminal 41c has a terminal piece 45c configured such that one side of another L-shaped bent piece 44C is folded downward to be flush with the - bent piece 42c.

In this case, when the container body 21 is assembled into the base body 1, the terminal piece 45c
will protrude to the lower surface of the base 1 through the terminal insertion holes i12, 13.

Therefore, in order to attach this product to a printed circuit board, it is sufficient to insert the base 1 horizontally onto the printed circuit board and then insert the terminal piece 45c projecting downward into the hole on the printed circuit board.

Next 1. When used for wrapping wiring, a wrapping wiring terminal 41d shown in FIG. 6 is used.

This wrapping wiring terminal 41d has a terminal piece 45d longer in length than the printed circuit board terminal 41C.

Therefore, the assembled state is the same as that for the printed circuit board, but for wiring, a terminal piece 45d protruding from the lower surface of the base 1 is wrapped with electric wire and soldered later.

Now, the above explanation is about 8 poles, but 4 poles.
In the case of configuring a polar tunnel, the seventh base body 1 is replaced with the base body 1.
It can be constructed simply by using the substrate 1a shown in the figure.

In this case, when used for a mount board, a mount board terminal 41a shown in FIG. 4a is used.

Note that in the above case, this external output check can be performed using, for example, a tester equipped with a dustbin at the tip.

This means that the test pin is inserted into the wire insertion hole 29, and the test pin is inserted into the terminals 41a, 41b, 41b,
This is based on the structure that contacts 1e and 41d.

According to the present invention, a device is provided in which first and second terminal insertion grooves are formed in a base body, and a terminal is incorporated into the base body to protrude to the outside through the first or second terminal insertion groove. Since the body is configured to be detachable, it can be used for printed circuit boards, mounting boards, and wrapping wiring by simply replacing the terminals.
