DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a modular adapter that is provided between a modular jack and a modular plug, and includes a plug part that is inserted into a modular jack and a jack part into which the modular plug is inserted. It is something.

[Background Art] Generally, a modular plug that is removably inserted into a modular jack is equipped with a lever that protrudes from the plug body so that it can be raised and lowered, and when the engaging part provided on the lever engages with the modular jack, the modular plug is inserted into a modular jack. It is held in the modular jack and can be pulled out by releasing the engagement between the modular plugs by operating a lever.

By the way, when such a modular plug is attached to a modular jack, there is a problem in that it is difficult to operate the lever because the amount of protrusion of the lever from the modular jack is generally small.

One possible solution to this problem is to install a modular adapter between the modular jack and the modular plug to facilitate lever operation. As such a modular adapter, one having a structure as shown in FIG. 4 has been considered. This modular adapter has a plug part 5 having the same structure as a modular plug protruding from the housing 1, a jack body 21 into which the modular plug is inserted, and a modular line insert 3 having a contact spring 32 connected to the modular plug. are provided in the housing 1, and a handle 43 for releasing the engagement state between the plug portion 5 and the modular jack is formed in a shape that protrudes from the housing 1 so as to be movable forward and backward. This handle 43
is provided with a cam surface 47 that pushes out a lever 52 provided on the plug section 5 to release the engagement state between the module jack and the plug section 5 when a pressing force is applied from the outside.

By the way, in this modular adapter, the housing 1 and the jack body 21 are separate bodies, and the plug part 5 and the modular insert 3
Since these were constructed separately, the number of parts incorporated into the housing 1 is relatively large.
There is a problem in that it takes time and effort to assemble the parts into the housing 1.

[Object of the Invention] The present invention has been made in view of the above points, and its purpose is to facilitate the work of assembling parts into the housing by reducing the number of parts at the time of assembly. Our goal is to provide modular adapters with

After being fitted into the fitting groove 8, they are thermally bonded by ultrasonic waves and are joined together. Here,
As shown in FIG. 2b, the fitting groove 8 is provided with a heat bonding allowance 10 which has a triangular cross-section and whose width narrows toward the back of the fitting groove 8. I am now able to wear clothes. Since the body 11 and the cover 12 are bonded together in this manner, there is no need to use screws or the like, making assembly easy.

The modular insert 3 has an insert body 31 made of synthetic resin, and is formed so that a part of a conductive linear spring material simultaneously molded on the insert body 31 protrudes from the insert body 31 as a contact spring 32. ing. contact spring 32
Two or more are provided, and as shown in FIG. 2B, they are inclined so that they extend from the plug insertion hole 13 toward the back of the housing 1 and gradually move away from the insert body 32. Further, the contact springs 32 are inserted with their tips separated one by one between the comb teeth 24 so as not to come into contact with each other, and retaining ribs 33 that fit into the retaining grooves 25 protrude from the side surface of the insert body 31. has been done.

On the other hand, a plug body 51 constituting the plug part 5
is made of synthetic resin and houses a contact 53 made of a plate of a conductive material, with a part of the contact 53 extending through a plurality of slits 54 formed on the top surface of the plug body 51. Each part is exposed throughout. A lever 52 is provided on the bottom side of the plug body 51.
is inclined and protrudes freely from the front end of the plug body 51 so as to gradually widen the distance from the plug body 51 toward the rear.
It is integrally formed from synthetic resin. Therefore, when the lever 52 is pressed toward the plug body 51, an elastic return force is accumulated, and when the pressing force is released from the lever 52, the lever 52 returns to its original position. An engaging portion 55 is formed in the middle of the lever 52, similar to the modular plug, and when the plug portion 5 is inserted into the modular jack, the engaging portion 55 engages with the modular jack. A flange 56 is formed at the base of the plug body 51, and this flange 56 is sandwiched together with the modular insert 3 between the front surface of the jack body 21 and the peripheral wall of the housing 1.

The modular insert 3 and the plug body 51 formed in the above shapes are connected by connecting the corresponding contact springs 32 and contacts 53 via the connecting wires 6, and are integrated into one as a whole. They are combined so that they can be treated as blocks. That is, the modular insert 3 and the plug body 51 form one adapter block. Therefore, as described above, the retaining protrusion 33 of the module line insert 3 is attached to the jack body 2.
The jack part 2 is formed by fitting the plug body 51 into the retaining groove 25 of the plug body 51.
and the peripheral wall of the housing 1, so that a part of the plug portion 5 protrudes from the housing 1. Lever 5 in plug part 5
2 is introduced into the housing 1 through the lever notch 16. In this way, since the modular insert 3 and the plug body 51 are integrated, two-core, four-core
When developing different types of cores, 6-core, etc., if several types of adapter blocks are prepared in advance, other parts can be shared, which has the advantage of facilitating the expansion of different types.

A handle 4 is housed within the housing 1. The handle 4 has one end edge of each of the pair of operation buttons 43 connected to each other via a connecting piece 44, and also includes a pair of operation buttons 43.
It is made of synthetic resin and has a shape in which an operating piece 45 extends from one end edge on the opposite side to the connecting piece 44 in 3. A thin hinge portion 46 is provided at the joint between the base operating button 43 and the connecting piece 44, and the operating button 43 can swing freely relative to the connecting piece 44 by the hinge portion 46. . Operation piece 4
5 are arranged so that their tips face each other, and are disposed between the flange 56 and the front peripheral wall of the body 11. Further, at the tip of the operation piece 45,
Cam surfaces 47 are formed so as to gradually reduce the distance from each other toward the bottom.
A notch 48 is formed at the upper end of the cam surface 47 to make the shape of the cam surface 47 discontinuous. This cam surface 47
are arranged so as to come into contact with both sides of the lever 52. Further, the inside of the operation button 43 is hollow and has a recess 49 formed therein, and the other end of the return spring 7, one end of which is located between the fulcrum projection 41 and the holding projection 42 described above, is inserted into this recess. It is stored in the space 49. The return spring 7 is a compression spring in the form of a coil spring, and is installed between each side wall 22 of the jack body 21 and each operation button 43, so that it is compressed when the operation button 43 applies a pushing force from the outside. Then, when the pressing force is released, it returns to its original position.

Operation button 4 of the handle 4 configured as described above
If a pushing force is applied from the outside to is the plug body 51
As a result, the engagement with the module jack can be released. In other words,
Since the engagement of the module jack is released by operating a relatively large operating button 43 instead of manually operating a small lever as in the conventional case, the operation becomes easier. The position of the notch 48 can be changed by pressing the operation button 43 on the lever 5.
The lever 52 is formed near the notch 48 on the cam surface 47 where the lever 52 is positioned when the engagement state between the module 2 and the module jack is released. By falling into this position, a click feeling is obtained, and the user can sense that the engaged state has been released. In addition, the handle 4 mentioned above
Since both operation buttons 43 are connected by a connecting piece 44 and formed integrally, handling becomes easy when assembling into the housing 1, and assemblability is improved. Further, since a hinge portion 64 is formed between the connecting piece 44 and the operation button 43 and abuts on the fulcrum protrusion 41 near the hinge portion 46, the fulcrum position is adjusted when the operation button 43 is operated. This improves stability and operability.

(Operation) When using the modular adapter A formed as described above, first, as shown in FIG. 3a, the modular plug B is inserted into the plug insertion opening 13 until it clicks. Modular plug B and modular adapter A are now connected.
Next, as shown in FIG. 3b, the plug portion 5 is inserted into the module jack C provided on the wall or the like until it clicks into place. In this state, the engaging portion 55 engages with the modular jack C, and the modular adapter A is connected to the modular jack C.

On the other hand, to remove the modular adapter A from the modular jack C, as shown in FIG. do. Modular adapter A can now be removed from modular jack C. Furthermore, if necessary, the modular plug B can be pulled out from the modular adapter A while pressing the lever D of the modular plug B, as shown in FIG. 3d.

[Effects of the Invention] As described above, the present invention has a housing that includes a plug part that is inserted into a modular jack and is engaged and held, and a jack part in which the modular plug is installed, and that protrudes from the housing so as to be movable forward and backward. In a modular adapter that is provided with a handle that releases the engagement state between the plug part and the modular jack when an extrusion force is applied from the outside, the plug part is a plug equipped with a contact that is electrically connected to the modular jack. It has a main body and a lever that protrudes freely from the plug main body and detaches from the modular jack as it goes up and down. The jack body has an opening for insertion of the plug into which the contact spring is exposed, and the jack body is integrally formed with the housing, and the plug body and the modular insert are integrally formed into a block. The plug body and modular insert are made into a block, and the jack body is integrally formed with the housing. This has the advantage of reducing the number of points and improving ease of assembly. In addition, since the modular insert and the plug body are made into blocks, it is possible to use 6-pole 2-core, 6-pole 4-core, 6-pole 4-core, 6-pole
If a block is formed that combines six poles, etc., it has the advantage that by simply replacing this block, other parts can be shared and different types can be developed.
