Description

[Detailed description of the invention] Conventionally, a jack with a switch used for plug insertion, in which all connection terminal blocks consisting of a set of multiple terminals that can be switched to a fixed terminal by operating a movable terminal, is fitted, is a jack with a switch that is used for plug insertion. This is related to a configuration in which the terminal block is fitted and disposed by providing a fitting groove on the inner circumferential surface, and since all the terminal groups are disposed within the casing, the terminal blocks are disposed in the casing. Therefore, an increase in the number of terminal blocks is difficult to design, and the number of fitting grooves increases in proportion to the increase in the number of fitting terminals. In addition, the design and manufacturing of the casing becomes more complicated and difficult, and the work of fitting each terminal into the predetermined groove requires highly skilled techniques, which has the disadvantage of reducing work efficiency and increasing costs. There is,
In addition, when deploying multiple terminals that utilize only the inside of a narrow case, the increase in the number of terminals results in an increase in the size of the device, making it extremely difficult to manufacture and provide small products. Since the terminal spacing is narrow, there are drawbacks such as the terminal switching performance due to plug operation tends to become unstable.

The present invention reliably eliminates the above-mentioned drawbacks of the conventional devices, and is equipped with a large number of connecting terminal blocks by preparing a connecting member separate from the container body, incorporating and equipping the connecting member with a desired number of terminal blocks, and equipping each of the connecting members with a desired number of terminal blocks. By configuring the movable terminal groups of the block so that they can be operated simultaneously by a push button mechanism related to one plug operation, and by connecting the connecting member to the container body, it is possible to operate the desired number of connection terminal blocks even in a single compact device. In addition, since the terminal block is assembled into a connecting member separate from the body, the work is extremely simple, and the switching performance of each terminal is ensured. In addition, by simplifying the box body and making it easy to manufacture the box body, and together with the simple manufacturing of the connecting member, the manufacturing cost is reduced,
Another object of the present invention is to provide a jack with a switch for plug insertion that is easy to manufacture, has stable performance, and is economical without increasing the overall size.

0 and is located below the movable contact piece 6 through the window hole 5 of the movable terminal 8.

Furthermore, the number of recesses of the connecting member 26 equipped with the switch terminal mechanism is the same as that of the connecting walls 16, 1 of the main body 3.
By changing the design of the spacing width of the push button 6' and changing the size of the member 26 fitted therein, the length of the push plates 31, 31' of the push button 32 can be increased or decreased by increasing or decreasing the number of recesses. The size is changed and the push protrusion 3

Additionally, the switch terminal mechanism is not limited to what is shown in the diagram.
Either a three-terminal or a two-terminal configuration may be used, and the mounting thereof is not limited to that shown in the drawings but may be arbitrary.

In short, the gist of the present invention is that a movable terminal 8, a ring terminal 12, and a ground terminal 11 are provided in the plug insertion hole 2.
Separately from the main body 3, a switch terminal mechanism is incorporated in the jack case main body 3, which has a simple mechanism in which a switch is fitted, so that the switch terminal mechanism can be operated all at once by the operation of one push button mechanism. The separately manufactured connecting member 26 is connected so that its push button mechanism is moved up and down by a spring when the movable contact piece 6 of the movable terminal 8 of the main body 3 is operated.

Since the present invention is constructed as described above, when the plug is inserted into the plug insertion hole 2 of the jack case body 3,
When the plug comes into pressure contact with each contact piece 11', 12' of the ground terminal 11 and ring terminal 12, the movable terminal 8
The movable contact piece 6 is brought into pressure contact with the movable contact piece 6, and the tip contact portion of the contact piece is pressed downward. As a result, a central part of the connecting member 26 is positioned directly below the contact piece 6 and pressed by the contact piece 6 through the notch groove 10 of the bottom surface 4 of the main body 3 and the window hole 5 of the movable terminal 8. When the head 29 of the insulated push button 32, which is fitted with a spring movement in the member 26, is pushed by the downward movement of the contact piece 6, the coil spring 33 is interposed in the insertion hole 21 of the member 26 so as to spring it up and down. The fitted push button 32 moves under the spring. However, since there is a guide protrusion 28 at the rear that loosely fits into the guide groove 20 and restricts the range of downward movement, this downward movement is caused by the protrusion 28 moving downward within the range of the guide groove 20. The range of downward movement is restricted, and at the same time, the vertical movement of the push button 32 is prevented from fluctuating. As the push button 32 moves downward, the push plates 31 and 31' connected to the rear left and right move downward, thereby causing the push projections 30 and 30' projected into the respective spaces 23 and 23' to move downward. Since the push plates 31, 31' are lowered simultaneously by the downward movement of the push plates 31, 31', the protrusions 30, 30' of the switch terminal blocks fitted and arranged in the spaces 23, 23' Each movable terminal 36, 36' is pressed with force from above, and their contact portions spring down and firmly contact the contact portions of each fixed terminal 35, 35' on the lower side. You will be forced to do so.

Next, when the plug is pulled out, the movable contact piece 6 in the main body 3 moves on a spring, so that the pressed button 32 moves on a spring. This spring movement is caused by the two-pronged engagement hook leg 27 at the bottom of the push button 32,
27' moves upward, and the stepped portion 1 in the insertion groove 21
8, 18' to stop it;
The push button 32 is fixed when the head 29 returns to a predetermined position below the movable contact piece 6 in the main body 3.

With this spring movement of the push button 32, the push plates 31, 3
Since the push protrusions 30, 30' move upward together with 1',
Each cavity 2 that was under pressure with the protrusions 30, 30'
The contact portions of the respective movable terminals 36, 36' within the movable terminals 3, 23' recoil and come into spring contact with the other fixed terminals 34, 34', thereby ensuring the switch action.

Therefore, as the movable contact piece 6 on the main body 3 side moves up and down by the spring due to the insertion and removal of the plug, one of the push buttons 32 of the connecting member 26 is subjected to the up and down movement of the spring, and the member 2
All of the switch terminal mechanisms assembled in the required number of six spaces 23, 23' are simultaneously operated. Therefore, as the desired number of switch terminal mechanisms increases or decreases, the number of spaces 23, 23' can be increased or decreased considerably, and the push plates 31, 31' of the push button 32 can be increased or decreased.
Due to the length and the correspondence between the numbers of push projections 30 and 30', it is possible to equip the connecting member 26 separate from the main body 3 with a desired number of switch terminal mechanisms, and each terminal mechanism can be equipped with one switch terminal mechanism. It has the function of being operated all at the same time by pressing a button.

The connection of the connecting member 26 to the main body 3 is achieved by attaching window holes 15 in the lower part of both longitudinal side walls of the main body 3.
By forming opposing connecting walls 16, 16' with 15' and providing engaging hooks 17, 17' on both sides of the material 26, which are engaged with the window holes 15, 15', The connection can be made easily and quickly by simply locking the hook pieces 17, 17' in the window holes 15, 15', and the terminal leg piece of the movable terminal 8 can be attached to the window hole 24 of the projecting surface 25 of the member 26 provided if necessary. 7, the movable terminal 8
As the member 26 is fixed, the rear end of the member 26 becomes a retainer, thereby reinforcing the connection and fixation.

As described above, in the present invention, by manufacturing the jack case body 3 and the connecting member 26 separately, the body 3
The configuration is extremely simplified, making manufacturing and assembly easy and efficient, and the switch terminal mechanism is installed separately from the main body of the case, instead of being targeted only at the narrow internal hole of the case as in the past. Hollow space 23 of connecting member 26,
23', the terminal assembling work can be done very quickly, simply and efficiently, and is extremely convenient.
By increasing and decreasing the desired number of 3 and 23' numbers, the number of switch terminal mechanisms is not limited and the desired number can be incorporated, which is very convenient, and the mechanism on the main body 3 side is simple, making it larger. The entire device can be assembled simply and quickly by fastening and connecting the connecting member 26 to the main body, making it possible to reduce the overall size and reduce costs. By simply increasing the size of the device, the volume of the entire device can be reduced, making it possible to provide an economical compact product.Also, even if the number of terminal mechanisms increases or decreases, a single push button mechanism can be used simultaneously and securely. Since the switch operation can be carried out with ease, and the terminals can be arranged with ease using the connecting member, the switch performance can be reliably stabilized.
