Description

The present invention relates to a modular plug holder that prevents accidents of the modular plug coming out of a modular jack.

Today, modular plugs used in businesses and homes are used to connect line cables for communication with communication devices such as telephones, modems, terminal adapters, routers, and network hubs. Specifically, a connector called RJ11 is often used to connect a telephone line cable, and an RJ45 connector is used to connect a LAN line cable.

The modular plug of RJ11 or RJ45 is provided with a locking claw (latch) for preventing the modular plug from coming off (reference numeral 4 in FIG. 2A). This locking claw is attached to the tip portion of the main body of the modular plug and is urged away from the plug main body by the elasticity of the material. The shape of the locking claw is formed from a wide portion to a narrow portion on the way from the mounting portion of the modular plug tip toward the line cable. When the modular plug is plugged into the modular jack provided on the LAN port etc., it is locked by the locking part that has a U-shaped groove that is narrower than the wide part of the locking claw formed at the entrance of the modular jack. The wide part of the claw is pressed so that it approaches the plug body. When the modular plug is further inserted into the back, the narrow part of the locking claw is inserted into the U-shaped groove of the locking part. This prevents the biased locking claws from moving away from the plug body, and prevents the wide part of the locking claws from catching on the locking part of the modular jack and moving in the direction to remove the modular plug (see Patent Document 1). ..

When the modular plug is disengaged from the modular jack, the locking claw is moved so as to be close to the main body of the modular plug, so that the locking part of the wide part of the locking claw is unlocked. Further, in order to protect the locking claws and improve the operability, many modular plugs have a claw cover serving as a locking claw pressing portion (reference numeral 5 in FIG. 2A).

In order to prevent unintentional disconnection of the connector, for example, as shown in Patent Document 2, a member for holding a line cable is provided in a housing to which a modular jack is attached, but the connector density is high such as a LAN hub. Not practical at the mounting site.

Therefore, a member for preventing movement of the locking claw is inserted between the locking claw and the modular plug body so that the locking claw does not move toward the main body of the modular plug (see Patent Document 3). ..

It is explanatory drawing of the dimension of the latching claw and claw cover of a modular plug. FIG. 5 is a side view of various modular plugs having modular plug boots. It is a development view of the first embodiment of the present invention. It is explanatory drawing of the adapter of this invention. It is an external view of the first embodiment of the present invention. It is an explanatory view of various module plugs and a module plug holder adapted to it. It is an external view of the 2nd Example of this invention. It is an external view of the 3rd Example of this invention. It is explanatory drawing of an example of a special screw and its driver.

(Example 1)
The modular plug holder 1 of FIG. 1 is shown attached to the modular plug 2. The modular plug 2 is connected to the line cable 3. When the portion of the modular plug 2 on the left side of the screen is inserted into the modular jack and fully inserted, it is locked to the modular jack by the locking claw attached to the left end of the modular plug. The shape of the modular plug is standardized in a portion to be inserted into the modular jack, but various shapes are commercially available for the connection portion with the line cable which is outside the modular jack.

FIG. 1B shows a modular plug having a bottom surface in which the bottom surface of the modular plug descends stepwise downward in FIG. 1 and has a step, and a modular plug holder corresponding thereto. A wall 55 corresponding to the step 7 on the bottom surface of the modular plug is provided.

The locking of the modular plug to the modular jack will be described with reference to the locking claws of the modular plug shown in FIG. RJ1 used for telephone lines and RJ45 used for LAN lines are standardized, and their outer diameter dimensions, connector terminals, locking claws, etc. are determined. Further, the inner diameter of the modular jack and the dimensions of the locking groove for locking the connector terminal and the locking claw terminal at the entrance are determined so that the modular plug can be received. The width of the locking groove is wider than the narrow portion of the locking claw and narrower than the wide portion of the locking claw.

When inserted into the modular jack from the terminal side of the modular plug shown in FIG. 2A, the wide portion (width=Wtw) of the locking claw 4 is pushed down by the locking groove provided at the entrance of the modular jack. The pawl 4 moves toward the main body of the modular jack, downward in the figure. When the insertion further proceeds, the narrow portion (width=Wtn) of the locking claw 4 that has been pressed down enters the locking groove of the modular jack and moves upward due to the elasticity of the locking claw. In this state, the wide portion of the engaging claw hits the locking groove of the modular jack and the modular plug cannot be removed from the modular jack.

Therefore, when pulling out the modular plug from the module jack, push down the locking claw 4 to bring it closer to the main body of the modular plug, and move it to a position where it does not hit the end of the locking groove provided at the entrance of the module jack. Move the modular plug toward the line cable.

In order to pull out the modular plug from the module jack, it is necessary to remove the locking claw 4 from the locking groove, and for that purpose, it is necessary to bring the locking claw 4 close to the main body of the modular plug. Therefore, in order to prevent unintended removal of the modular plug from the modular jack, it is effective to cover the locking claw 4 so that the locking claw cannot be touched from the outside. Here, since the portion of the modular plug 2 protruding from the modular plug holder 1 to the left of FIG. 1 is inserted into the modular jack, it is difficult to touch the locking claw from the outside.

The locking claw is a modular plug standard and is common to all modular plugs, but other shapes are available in consideration of usability. FIG. 3 shows an example thereof.

Among the assembled modular plugs on the market, there is a modular plug in which a modular plug boot 8 is attached to the modular plug to protect the line cable as shown in FIG. For protection against bending of the line cable, the modular plug boot 8 is engraved in a direction substantially perpendicular to the extending direction of the line cable.

In addition, the shape of the modular plug body is also composed of a first part to be inserted into the modular jack and a second part for fixing the line cable as shown in FIGS. Some have stepwise steps 7. For such a module plug, by applying the movement prevention adapter 60 as shown in FIG. 5 which serves as a movement prevention member for preventing the movement of the module plug holder to the modular plug shown in FIG. Movement can be prevented.

Here, reliable prevention of the movement of the locking claw will be described with reference to FIG. FIGS. 4A and 4B are development views of the modular plug holder 1 of FIGS. 1A and 1B. FIG. 4(A) corresponds to a modular plug having a stepped bottom surface, and FIG. 4(B) corresponds to a modular plug having a stepped bottom surface. Here, the side inserted into the modular jack is called the front side, and the side to which the line cable is connected is called the rear side. The modular plug holder 1 is composed of constituent members that partially cover the remaining surfaces of the modular plug 2 other than the front surface and the rear surface. When this is manufactured as an integral body by injection molding or the like, it is preferable to divide the plug module in the vicinity of the center line in the width direction of the plug module as shown in this development. It includes a hinge 17 that is thinly formed and easy to fold so that a plurality of components can be bent and used.

FIG. 4(A) shows a module plug holder for fixing a module plug having a flat bottom surface as shown in FIG. 2(A) mainly by tightening when assembling the module plug holder. Further, FIG. 4B shows a module plug holder that prevents the module plug from moving in the line direction by using a step on the bottom surface of the module plug or by using notches in the modular plug boot. A movement preventing wall 55 is provided on the front surface in order to utilize the step 7 on the bottom surface of the module plug.

Here, the movement prevention adapter to be mounted on the module plug holder later as a separate component will be described with reference to FIG. Some module plugs include modular plug boots 8 shown in FIG. 3, which have knurled members formed for protection of a line cable. The movement prevention protrusion 24 provided on the upper surface of the movement prevention adapter 60 of FIG. 4 serves as a movement prevention member of the module plug. The lower surface of the movement prevention adapter 60 is provided with a locking projection 26 that fits into the hole 27 of FIG. 4B for locking the movement prevention adapter to the module plug holder. The direction a in FIG. 5 is the front side, that is, the modular jack side, and the b is the rear side, that is, the line cable side.

The distance between the movement preventing protrusion 24 and the locking protrusion 26 of the movement preventing adapter 60 of FIG. 5 can be changed according to the purpose. For example, the module plug holder shown in the development view of FIG. 3B is placed, the b of the adapter 60 shown in FIG. 4 is placed on the front surface of the adapter module holder, and the a is placed on the rear surface. Then, the right coupling portion and the left coupling portion are combined and coupled so as to cover the module plug. The distance between the movement preventing protrusion 24 and the locking protrusion 26 is selected so that the movement preventing protrusion 24 of the movement preventing adapter 60 is located on the front side of the step 7 in FIGS. When the plug holding portion is moved in the direction of the line cable, the movement preventing protrusion 24 contacts the step 7 and prevents the module plug from moving in the direction of the line cable.

The upper side of the development view shown in FIG. 4 is the front side that is inserted into the modular jack of the modular plug, and the lower side of FIG. 4 is the rear side that the line cable of the modular plug is in and out. When mounting the modular plug holder 1 on the modular plug 2, first, the central bottom surface portion 12 is applied to the bottom portion of the modular plug without the locking claws. Then, the left side surface portion 11 and the right side surface portion 13 are bent at the hinge 17 and are raised to cover the modular plug 2. Then, the left upper surface portion 15 and the right upper surface portion 16 corresponding to the upper portion of the modular holder become substantially flat to form the head portion of the modular plug holder, and the hole 18 and the hole 19 opened in the connecting portion are coaxial with each other. Face each other.

When the modular plug is covered so as to wrap it, the locking claw movement preventing members 14, 14' for preventing the movement of the locking claw located above in FIG. 4 are inserted into the gap between the locking claw 4 and the main body of the modular plug. To be done. By inserting the locking claw movement preventing members 14, 14' into the gap between the locking claw 4 and the body of the modular plug, for example, pressing the locking claw with a thin plate from between the modular jack and the modular plug. Is prevented.

In this state, the screw is passed through the holes 18 and 19 of the coupling portion and the screw is tightened. A nut may be embedded in the hole 19 side, but by forming a spiral groove in the hole 19, a nut as a separate member becomes unnecessary. Here, if the widthwise dimension of the space formed by the left side surface portion 11 and the right side surface portion 13 is made smaller than the width dimension of the modular plug, the left side surface portion 11 and the right side surface portion 13 are respectively closed by tightening the screws. The modular plug holder is fixed to the modular plug by being strongly pressed against the left side surface and the right side surface of the.

Further, if a thin film of rubber or a flexible organic resin is attached to the inside of the left side surface portion 11 or the right side surface portion 13 of the modular plug holder, the frictional force with the side surface of the modular plug increases and the modular plug Fixing of the plug holder can be performed more easily.

Further, by sticking a thin film of rubber or a flexible organic resin to the facing surfaces of the coupling portion, the gap formed between the upper left surface portion 15 and the right upper surface portion 16 when the screw is tightened is filled, and the appearance is improved.

Here, a state in which the movement of the modular plug holder is hindered by the claw cover will be described in detail with reference to FIG. The width of the front opening 25 of the modular plug holder 1 (the lateral dimension when the locking claw is positioned at the top when the modular plug is viewed from the connector side) is equal to the width Wtn (the width of the narrow part of the locking claw). It is wider than that in FIG. 2B, and the locking claw can freely move in the vertical direction within the opening range of the front opening 25.

As shown in FIG. 2(C), when the modular plug is inserted into the modular jack, it is pressed against the locking wall 50 of the modular jack. The locking claw 4 moves toward the main body of the modular plug and passes through the locking wall 50 of the modular jack, and then moves upward due to the elastic force of the narrow part (width=Wtn) of the locking claw to move the locking claw. The wide portion (width=Wtw) is locked by the locking wall 50, and the modular plug is locked to the modular jack.

At that time, the hanging wall portions 22 and 23 in FIG. 4 are located on the front surface side of the claw cover 5 on the modular jack side, as shown in FIG. The distance Hhm1 from the upper surface of the modular plug at the lower ends of the hanging wall portions 22 and 23 is set smaller than the distance Hmc2 from the upper surface of the modular plug at the upper end of the tip portion of the claw cover 5. Therefore, when the modular plug holder is moved to the right in the figure, the hanging wall portions 22 and 23 come into contact with the tip end portion of the claw cover 5, so that the hanging wall portions 22 and 23 extend in the line direction of the modular plug of the modular plug holder. It will prevent movement.

The shape of the front opening 25 will be described with reference to FIG. 6, which is an external view of the first embodiment. The front opening 25 is an opening into which the locking claw 4 is inserted. The hanging walls 22 and 23 are provided so as to hang down from the upper end of the front opening 25. By applying the modular plug holder having the hanging wall portion to the modular plug with the claw cover 5, it is possible to prevent the modular plug holder from slipping out in the line direction of the modular plug as described above.

Below the opening 25 of FIG. 6, the protrusions 14 and 14' are formed as a locking claw movement preventing material. The protrusions 14 and 14' are inserted between the locking claw 4 and the body of the modular plug to prevent the locking claw from being pressed downward.

FIG. 7 shows how the modular plug holder corresponding to each of the boot-attached module plugs shown in FIG. 3 is prevented from coming out of the modular plug. In FIG. 7A, the modular plug having no claw cover is held by using the movement preventing adapter 60 by utilizing the notches of the boot.

In FIG. 7B, the upper end of the claw cover 5 with the claw cover 5 contacts a hanging wall on the front surface of the modular plug holder to prevent the modular plug holder from moving. 7(c) and 7(d) both show the step 7 on the bottom surface of the modular plug, and the step prevention wall 55 contacts the step 7 to prevent the modular plug holder from moving.

(Example 2)
FIG. 8 is an external view of the modular plug holder 30 of the second embodiment of the present invention. Also here, when there is a step on the bottom surface of the modular plug, the modular plug holder provided with the movement preventing wall 55 as shown in FIG. 6B is applied. The dotted line shows the internal structure. When opened in the left-right direction, the shape becomes similar to that of FIG. 4 of the first embodiment. The bottom surface of the modular plug 2 is applied to the bottom surface portion 37, the side walls 31 and 32 are raised so as to wrap the modular plug, and the left and right are tightened so that the holes of the coupling portion are coaxial. The difference from the first embodiment is that the connecting portion is provided at the position of the connecting portion. In the second embodiment, the modular plug and the modular plug holder are fixed by sandwiching the modular plug from above and below. A convex portion 39, which serves as a modular plug restraining portion, is formed slightly downward as compared with the connecting member.

In order to tighten and fix the modular plug holder 1 to the modular plug 2, when the modular plug holder is assembled, a portion that is slightly smaller than the outer dimension of the modular plug in the fixing direction is useful. Here, the convex portion 39 is formed downward in the fixing direction of the modular plug holder shown in FIG. 8 to reduce the opening size.

The modular plug holder 30 can be assembled by passing the screw through the hole 28 provided in the coupling portion and screwing the screw into the nut of the hole 29 or the groove formed in the hole 29. By adjusting the tightening degree of the screw, it is possible to adjust the fixing strength between the pressing convex portion 39 on the right side surface which is the modular plug pressing portion of the modular plug holder and the upper surface of the main body of the modular plug 2.

When the modular plug 2 is wrapped and covered with the modular plug holder 30, the terminal side of the modular plug is positioned on the right side of FIG. 8 and the line cable is positioned on the left side of FIG. In this state, the protrusions 35, 35' are inserted into the gap between the locking claw 4 and the upper surface of the main body of the modular plug as a locking claw movement preventing member, so that the locking claw 4 can be prevented from unintended movement. it can.

Since the modular plug holder 30 has the holes 28 and 29 of the coupling portion located on the upper surface, the work for mounting and fixing the modular plugs arranged on the hub and the like can be performed from the upper surface.

(Example 3)
Next, an example of applying the present invention when a plurality of modular plugs are mounted side by side will be described with reference to FIG.

The retention of two or more modular plugs is within the scope of the invention. Although one modular plug is shown in FIG. 9, it is often the case that modular plugs are mounted on all the holding portions.

Unlike the cases of the first and second embodiments, the first constituent member 41 and the second constituent member 42 of the modular-plug holder 40 are separably formed. The second constituent member 42 holds the bottom surface side of the modular plug 2, and the first constituent member 41 holds the upper surface side of the modular plug 2 with the locking claws.

After the bottom surface side of the modular plug is held by the second component member 42, the first component member 41 is covered to cover the modular plug, and after that, the protrusion 45 is slid in the left direction (← direction) of the drawing and the projection 45 is locked. And the top of the modular plug body.

The position of the first component member 41 is adjusted so that the holes 48 and 48' provided in the coupling portion of the first component member 41 are coaxial with the holes 49 and 49' provided in the second component member 42. Then, fix them by connecting with screws. In this state, the protrusion 45 is inserted into the gap between the locking claw and the upper surface of the modular plug body. In order to prevent the component member from hitting the modular plug during the shifting process for fixing, the width of the component member 41 in which the modular plug is fitted is formed to have a predetermined size including a distance for shifting.

In the case of FIG. 9, since the modular plug holders that hold the five modular plugs are coupled by the two coupling portions, it is possible to manage the coupling portions less than the number of the modular plugs to be managed, and the individual modular plugs. Management becomes easier than when a holder is used.

Management of the modular plug retainer leads to management of the screws that join the joints. Using a special screw makes it difficult for an intruder to act. For example, the hexagonal wrench screw shown in FIG. 10 has a protrusion on the head portion for receiving the hexagonal wrench, and a normal hexagonal wrench cannot be used. A special hex wrench with a hole in the center is required to turn this screw. The modular plug holder can be managed by preparing a special screw and a set of tools for turning the special screw according to the importance of the management system.

As described in detail above, the present invention makes it possible to provide an inexpensive modular plug holder that reliably prevents unintentional withdrawal of the modular plug.
