Description

[Detailed Description of the Invention] This invention relates to a general-purpose jack that can be used with standard plugs and mini plugs.

The main types of plugs and jacks used in audio, VTR, etc. are 6.5φ type called standard plug and 3.5φ type called mini plug. However, there is no compatibility between the two, and if you really want to connect them, you have to use an adapter.

This invention was made for the purpose of solving such drawbacks of the conventional technology, and this invention
The slide piece is slidably inserted into a pair of slide holes that are bored facing each other from approximately the middle of the 6.5φ jack to one end of the lead wire outlet, and into the inside of the 6.5φ jack, and the spring for the 6.5φ plug is inserted. The contacts are arranged so that they do not contact the slide piece even if the slide piece slides, and contact the 6.5φ plug inserted from the plug insertion hole at the other end of the 6.5φ jack.
Place one end of the 3.5φ jack on the inner circumferential surface of the 6.5φ jack, and the spring contact for the 3.5φ plug is placed on the inner circumferential surface, and fix the end of the 3.5φ jack to the plug insertion side side of the center of the slide piece, and then is attached between a protrusion protruding from the outer peripheral surface of the other end of the 6.5φ jack and a protrusion of the slide piece.

This invention will be explained below based on the drawings.

FIG. 1, FIG. 2, and FIG. 3 are diagrams showing an embodiment of this invention.

First, to explain the configuration, 1 is a slide piece,
A pair of slide holes 3, 3' are formed facing each other from approximately the middle of the 6.5φ jack 2 to one end serving as a lead wire outlet, and the wire is inserted into the 6.5φ jack 2. The slide piece 1 has a central portion 1 that is inserted into the slide holes 3, 3' and the inside of the 6.5φ jack 2.
A and protruding pieces 1B, 1 that protrude from the outer peripheral surface of the 6.5φ jack 2 and are larger than the central part 1A.
It is composed of B′.

The inner peripheral surface of the 6.5φ jack 2 is provided with spring contacts 2A and 2B for a 6.5φ plug. The spring contacts 2A and 2B for the 6.5φ plug do not contact the slide piece 1 even if the slide piece 1 slides, and the spring contacts 2A and 2B for the 6.5φ plug
It is arranged so as to contact a 6.5φ plug inserted from the plug insertion opening at the other end of the jack 2.

The slide holes 3, 3' have straight parts 3A, 3A' on which the slide piece 1 slides, and straight parts 3A, 3.
Stopper parts 3B, 3B' are provided at one end of A' in a direction perpendicular to the straight parts 3A, 3A' and prevent the slide piece 1 from sliding to the right;
The stopper portions 3C and 3C' are provided at the other end of the slide member 3A' in a direction perpendicular to the straight line portions 3A and 3A' to prevent the slide piece 1 from sliding to the left. The stopper portions 3B, 3B' are provided in opposite directions, and the stopper portions 3C, 3C' are provided in opposite directions.

4 is a 3.5φ jack, which is inserted into the 6.5φ jack 2, and one end of which is connected to the center part 1 of the slide piece 1.
It is fixed to the side of A on the plug insertion side. Also,
At the other end, the slide piece 1 is connected to the slide holes 3 and 3'.
in the state of being located at one end of the straight line parts 3A, 3A',
It is located at the same position as the other end of the 6.5φ jack 2 or inside the other end. Spring contacts 4A and 4B for the 3.5φ plug are provided on the inner peripheral surface of the 3.5φ jack 4, and a lead wire 4C is connected to one end of the spring contact 4A and 4B for the 3.5φ plug.
The lead wire passes through the inside of the 6.5φ jack 2 and comes out from the lead wire outlet.

5 and 5' are springs, which are attached between a pair of protrusions 6 and 6' protruding from the outer peripheral surface of the other end of the 6.5φ jack 2 and protrusions 1B and 1B' of the slide piece 1. There is. Although two springs are used, one coil spring with the protruding piece 6 or 6' larger than the outer diameter of the 6.5φ jack 2 is used, and the 6.5φ jack 2 is installed inside the coil spring.
You may insert a part of it.

Next, the action will be explained.

When both the 6.5φ plug and the 3.5φ plug are not used, the slide piece 1 is moved into the straight part 3 of the slide hole 3, 3' by the action of the springs 5, 5'.
A, 3A' is fixed at one end.

Next time, when using the 3.5φ plug, lightly insert the 3.5φ plug into the 3.5φ jack 4 and rotate the 3.5φ plug to the left. As a result, the 3.5φ jack 4 and the slide piece 1 are also rotated to the left, and the slide piece 1 is moved to the stopper part 3B of the slide hole 3, 3'.
Enter 3B'. Therefore, sliding in the straight portions 3A, 3A' of the slide piece 1 is prevented, so when the 3.5φ plug is inserted more forcefully, the 3.5φ plug is completely inserted into the 3.5φ jack 4, and the spring contacts 4A, 4B come into contact with.

When pulling out the 3.5φ plug, first rotate the 3.5φ plug clockwise to return slide piece 1 to its original state, and then pull out the 3.5φ plug.

When using a 6.5φ plug, use a 6.5φ plug.
Insert it into 6.5φ jack 2. This results in
The 3.5φ jack 4 is pushed by the tip of the 6.5φ plug, and the slide piece 1 is pushed by the straight part 3A of the slide hole 3, 3'.
Slide 3A'. In this process
The 6.5φ plug contacts spring contacts 2A and 2B. The slide piece 1 is the straight part 3A of the slide hole 3, 3',
When you reach the other end of 3A', rotate the 6.5φ plug to the right. As a result, the 3.5φ jack 4 and the slide piece 1 rotate to the right, and the slide piece 1 enters the stopper portions 3C and 3C' of the slide holes 3 and 3'. Therefore, while the 6.5φ plug is in use, the slide piece 1 is held by the stopper portions 3C and 3C'.

When pulling out the 6.5φ plug, first rotate the 6.5φ plug to the left to return the slide piece 1 to the other end of the straight portions 3A, 3A' of the slide holes 3, 3', and then pull out the 6.5φ plug. As a result, the slide piece 1 slides on the straight portions 3A, 3A' of the slide holes 3, 3' by the action of the springs 5, 5', and the 3.5φ jack 4 and the slide piece 1 return to their original states.

Due to this simple operation, it can be used with standard plugs and mini plugs without using an adapter. By adding a spring contact, it can also be applied to stereo three-pole plugs.

As explained above, this invention involves inserting a 3.5φ jack inside a 6.5φ jack, fixing a slide piece to the 3.5φ jack, and a pair of slide holes drilled in the 6.5φ jack. Approximately 6.5φ
Standard The effect is that it can be used for plugs and mini plugs.
