Description

Patch cord connector and patch cord having same

The present invention relates to a patch cord connector and a patch cord having the same. More specifically, the present invention relates to a patch cord connector having improved workability of detaching a patch cord connector of a worker from a patch panel composed of a multilayer, and a patch cord having the same.

In general, patch cords are constructed in such a way that patch cord connectors are connected at both ends of the cable. The patch cord connector includes a boot for supporting a cable, a conductor wire constituting a plurality of pairs of cables, and an RJ45 standard plug for connecting and connecting a connection terminal exposed to the inside.

FIG. 1 shows an example of a patch cord connector of a conventional patch cord, and FIG. 2 shows a connection state of a patch cord to a patch panel of a general data center or a computer room.

The plug of the RJ45 standard constituting the patch cord connector is standardized, and the boot behind the plug is plugged after the connection work of the plug constituting the cable and the patch cord connector is completed as shown in FIG. 1 (a). It can be formed by insert injection method so as to surround a part of the cable of the inner region and the plug rear region, and as shown in Fig. 1 (b), the boot is made of a separate injection molding plug and a cable and a patch cord connector It may be fitted to the cable prior to the connection work.

The boot may be provided for the purpose of protecting the cable from preventing the cable from bending at the boundary area between the cable and the plug, or preventing foreign matter from entering into the plug.

In addition, in the case of a boot mounted before the connection of the cable and the plug (connection terminal) shown in FIG. 1 (b), the plug accommodates the end of the latch for releasing the fixing state mounted at the patch cord connector insertion hole of the patch panel. It may have a structure, it is possible to obtain the effect of reducing the breakage of the latch that can be easily broken by such a structure.

A latch step and a latch may be provided in a state inclined obliquely backward from the front end of the upper surface of the plug constituting the patch cord connector. The locking step is inserted into the patch cord connector insertion port of the patch panel and performs a function of locking the locking step of the insertion port so that the patch cord connector of the patch cord is not separated, and the latch of the plug is narrowed from the locking step. It is configured to extend integrally, it can perform a fixed state release function for pressing down the locking step so that the fixed state to the locking step of the locking step can be selectively released. That is, in the process of mounting the latch step and the latch in the patch cord connector insertion hole in the inclined direction, the inclined upper surface of the locking step is pushed down and inserted into the connector insertion hole without any operation in the process of being inserted into the patch cord connector insertion hole. Can be fixed.

As shown in FIG. 2, in a computer room or a large data center, patch cords and patch panels are connected and installed in large quantities.

In this case, the patch panels are stacked in multiple layers, and the spacing between the layers is considerably narrow, and dozens of patch cord connector insertion holes for connecting the patch cord connectors of the patch cords of the respective patch panels are provided in each layer, and dozens are provided in a line up and down Also provided as a multilayer. For convenience of description, FIG. 2 illustrates an example in which the patch cord connector insertion layer is formed of three layers, but may be increased or decreased.

In this environment, the operator who connects or disconnects the patch cord to the patch cord connector insert of the patch panel must insert or detach the patch cord precisely and quickly into each patch cord connector insert. Falls. In particular, in the patch panel shown in Figure 2, in order for the operator to separate the patch cord connectors of the patch cord mounted on the patch cord connector insert of the second layer, patch cord connectors of the patch cord are respectively inserted into the first and third layer patch cord connector inserts. In the inserted state, the latch of the plug constituting the patch cord connector of the patch cord to be separated on the second layer is pressed to release the state where the locking step of the plug is fixed to the locking jaw of the patch cord connector insertion hole of the patch panel.

However, as shown in FIG. 2, the operation of separating the patch cord connector of the patch cord inserted into the patch cord connector insertion hole is performed by separating the patch cord connector of the patch cord due to the narrow spacing between the patch cord connector insertion holes of the patch panel. Although the latch must be pressed by the operator's finger, the task of removing the patch cord connector from the patch cord connector insertion hole is considered to be inferior in workability or cumbersome work considering the diameter of the operator's finger.

In addition, when a force applied to a worker's finger or the like in a narrow space is unnecessarily large, a latch having a structure that is easily broken is often broken.

Therefore, there is a need to provide a patch cord connector having improved workability for detaching a patch cord connector from a patch panel composed of a multilayer and a patch cord having the same.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments introduced herein are provided so that the disclosure may be made thorough and complete, and to fully convey the spirit of the invention to those skilled in the art. Like numbers refer to like elements throughout the specification.

The present invention is to provide a patch cord connector and a patch cord having the same improved workability of the operator's separation of the patch cord connector from a multi-layer patch panel, the conductor wire and the connecting terminal constituting the cable of the patch cord is connected inside A plug having a latch for releasing the locking step of the patch cord connector insertion hole of the patch panel and a latch for releasing the locking state of the locking step of the locking step; and a cable inserted into the plug from the rear of the plug And a boot mounted to the rear of the plug so as to be displaceable with respect to the plug, wherein the boot is pressed against the plug by the latch of the plug when the plug is displaced from the plug. Patch cord connector to release jams Provided.

In the description of the present invention, the patch cord means a communication cable unit connected to a patch cord connector including RJ45 standard plugs at both ends of the cable, and the cable includes a conductor wire spirally wound to have a different pitch of a plurality of pairs. Means a standard communication cable.

The patch cord connector according to the present invention displaces the boots constituting the patch cord connector with respect to the plug in order to easily detach the patch cord connector in a narrow work space without directly pressing the latch of the plug with the finger of the operator. The latch is pressed in the process of being displaced with respect to the plug, thereby improving the operator's convenience in detaching the patch cord connector.

Here, the latch provided in the plug is pressed by the displacement operation of the boot, so that the user does not have to push the finger to the extremely narrow area. That is, the workability can be improved because the patch cord connector can be separated from the patch panel by displacing the boot located at a large space of the rear of the plug.

A method of rotating the boot by the displacement method of the boot for pressing the latch on the upper surface of the plug may be used. 3 to 5, the patch cord connector 100 according to the present invention will be described.

3 shows a perspective view of one embodiment of a patch cord connector 100a of a patch cord according to the invention, and FIG. 4 is a top view of a patch cord connector 100a of a patch cord according to the invention shown in FIG. , A right side view, a left side view, and FIG. 5 is a front view of an operating state of the latch 11a according to the rotation of the boot 20a of the patch cord connector 100a of the patch cord according to the present invention shown in FIG. 3. Illustrated.

The patch cord connector 100a according to the present invention is applied to the plug 10a of the standard standard (RJ45a) like the general patch cord connector 100a, and the present invention is also inserted into the patch cord connector insertion hole of the patch panel and is fixed. Like the conventional patch cord connector 100a, the latch step 13a located at the bottom of the latch 11a by pressing the latch 11a provided on the upper surface of the plug 10a is caught by the patch cord connector insertion hole of the patch panel. It has a structure that separates it from the jaw 411a.

The boots 20a constituting the patch cord plug 10a illustrated in FIGS. 3 to 5 are rotatably mounted around the cable 50a at the rear of the plug 10a, and the plug 10a is rotated. It is possible to have a structure to push down the latch (11a) of the bottom).

3 to 5, the connection member 30a is provided between the plug 10a and the boot 20a. The plug 10a constituting the patch cord connector 100a has a substantially rectangular parallelepiped shape according to the RJ45 standard, and the boots 20a are configured to have a substantially rounded cross section because the boot 20a is rotated. Therefore, the connection member 30a may be interposed therebetween so as to alleviate the difference in the shape of the rear surface of the plug 10a and the front surface of the boot 20a and not to protrude sharp edges such as the plug 10a. .

The connection member 30a has a structure fixed to the plug 10a and may have a structure in which only the boots 20a are relatively rotated with respect to the connection member 30a and the plug 10a.

3 and 4, the boot 20a is a cable support 23a for supporting the cable 50a inserted into the plug 10a and the plug (a) at the cable support 23a. It may be configured to include a cover portion (21a) extended in the form of a cover surrounding a portion of 10a).

In addition, the latch 11a and the locking step 13a of the plug 10a are formed to be inclined in the rearward direction and the upward direction from the front end of the plug 10a, and the locking step 13a of the plug 10a. Is a narrowing area.

The cable support part 23a has a structure through which the cable 50a penetrates and prevents the cable 50a from being bent, and a cover part extended from the cable support part 23a to the plug 10a in a cover shape. 21a is provided so that the latch 11a of the plug 10a can be pressed against the lower surface of the cover portion 21a during rotation. That is, the cover portion 21a is configured to cover only a part of the plug 10a, not a structure that surrounds the plug 10a, so that the latch 11a boots only when the boot 20a is rotated. This is to adopt a structure pressurized by the cover portion 21a of the 20a.

3 to 5, the lower surface of the cover portion 21a of the boot 20a presses and latches the latch 11a of the plug 10a during the rotation of the boot 20a. The locking step 13a of the boot 20a may be lowered to release the locked state to the locking step of the patch cord connector insertion hole.

3 and 4 illustrate a state in which the cover portion 21a of the boot 20a is positioned at a first position where the cover portion 21a is not rotated. In the first position, the end portion of the cover portion 21a constituting the boot 20a does not interfere with the latch 11a of the plug 10a.

However, when the boots 20a are rotated to the second position as shown in FIG. 5 (b) by rotating the boots 20a in the state where the boots 20a are positioned in the first position of FIG. The lower surface of the cover portion 21a of 20a is pushed down by the latch 11a, and the locking step 13a which is integrally formed with the latch 11a is also lowered. The locking state of the locking step of the patch cord connector insertion hole of the patch panel may be released.

Therefore, even in an environment in which patch panels having dozens of patch cord connector insertion holes are stacked in a plurality of layers, a worker presses a finger to press a latch 11a of a patch cord connector 100 that needs to be separated into a narrow space. Rotating the boot 20a located in the rear relative clearance without the insertion as shown in Fig. 5 (b), the locking step 13a integrally formed with the latch 11a is lowered to be separated from the patch panel. Can be.

And, as shown in Figure 5 (a), it can be seen that the cover portion 21a of the boot 20a is inclined with a sharp inclination θ at an angle of 45 degrees or more.

Therefore, in the first position where the boot 20 is not rotated, the end portion 411a of the cover part 21a may be maintained near the latch 11a without interfering with the latch 11a. In the process of rotating the boot 20a to the second position, the bottom surface of the cover portion 21a immediately enters the bottom surface of the cover portion 21a by pressing the upper end of the latch 11a, and the boot 20a. As the rotation progresses, the latch 11a may be lowered by a size enough to release the locked state of the locking step 13a along the lower surface of the cover portion 21a.

In addition, the boot 20a is necessary only when the cover portion 21a presses the latch 11a only when the patch cord connector 100a is detached from the patch panel, and the latch 11a is unnecessary. Since it is not desirable to interfere with 21a), the boots 20a can be configured to return to the first non-rotated first position.

Thus, an elastic member (not shown) is provided between the boot 20a and the connection member 30a to provide an elastic restoring force, thereby providing restoring force when the boot 20a is rotated.

Figure 6 shows a perspective view of one embodiment of a patch cord connector 100b according to the present invention, Figure 7 is a top, right side view of the patch cord connector 100b of the patch cord according to the present invention shown in Figure 3 8 shows a left side view, and FIG. 8 shows a front view of an operating state of the latch 11b according to the rotation of the boot 20b of the patch cord connector 100b according to the present invention shown in FIG. 3. Descriptions duplicated with those described with reference to FIGS. 3 to 5 will be omitted.

As described above, the plug 10b for the patch cord connector 100b of the RJ45 standard is formed with a latch step 13b and a latch 11b inclined backward from the front end of the upper surface of the plug 10b. The latch 11b may be provided to press and release the latching state to the patch panel by the latching step 13b.

Therefore, since the latch 11b is made of a material that is repeatedly pressed or its thickness is made of a thin and inflexible resin material, the latch 11b may be easily damaged by an external impact.

Therefore, the patch cord connector 100b and the patch cord having the same according to the present invention shown in Figs. 6 to 8 have a first position in which the boot 20b is not rotated to prevent damage of the latch 11b. In the present embodiment, the rotation direction end portion 211b of the cover portion 21b surrounds the latch 11b.

6 to 8 also have a structure in which the boot 20b extends so that the rotational end 211b of the cover portion 21b surrounds the latch 11b in a first position, but in a first position. When the cover portion 21b of the boot 20b when rotated to the second position is to be configured to be released by pressing the latch 11b to release the fixed state.

In addition, the latch 11b of the patch cord connector 100b according to the present invention is composed of a resin material which is repeatedly pressed or its thickness is also thin and inflexible, so that the latch (b) is prevented from being easily broken during the pressing process. A support protrusion 17b for supporting the latch 11b pressed in the lower space of the 11b) may be provided.

As shown in FIGS. 7B and 7C, the support protrusion 17b supports the bottom surface of the latch 11b pressed from the top surface of the plug 10b so that the boots 20b are supported. The latch 11b may be supported so that the latch 11b does not sag due to the weakening or damage of the latch 11b in the non-rotated first position.

That is, when the latch 11b is unnecessarily pressed, the support protrusion 17b supports the lower surface of the latch 11b to prevent the latch 11b from breaking, and even when the latch 11b is damaged and the elasticity is reduced. By preventing the latch 11b from sagging, it is possible to ensure a locking function of the locking step 13b formed at the rear end of the latch 11b.

9 illustrates a process of separating the patch cord connector 100a of the patch cord according to the present invention shown in FIG. 3 from the patch cord connector insertion hole of the patch panel.

Like the patch panel shown in FIG. 2, the patch cord connector insertion hole 410 of the patch panel 400 is formed in a plurality of layers, and even if the free space is narrow, the patch cord connector insertion hole 410 is inserted into the patch cord connector insertion hole 410. The cable 50a patch cord for the separation of the patch cord connector 100a fixed by the locking step 411 of the insertion hole 410 and the locking step 13a of the patch cord connector 100a and the plug 10a. By holding and rotating the cable support 23a of the boot 20a constituting the connector 100a, the patch cord connector 100a can be detached from the patch cord connector insertion hole 411 of the patch panel 400 easily.

When the cable support part 23a of the boot 20a constituting the patch cord connector 100a is grasped and rotated to separate the patch cord connector 100a, the cover part 21a of the boot 20a is rotated together and the boot ( The latch 11a of the plug 10a disposed on the lower surface of the cover portion 20a can be pushed downward to release the locking state of the locking step 13a. In this case, the operator can patch as shown in FIG. 9 (b). The patch cord connector 100a can be easily removed from the patch cord connector insertion hole of the panel.

In order to prevent slippage when the operator grasps and rotates the cable support 23a of the boot 20a, a raised jaw-shaped unevenness 23a is formed on the upper part of the cable support 23a of the boot 20a. It may be provided.

At least one unevenness 23a may be formed in a direction perpendicular to the displacement direction of the boot 20a. 3 to 9, the unevenness 23a may be formed on the cable support 23a of the boot 20a in a direction perpendicular to the rotation direction of the boot 20a or in a rotation axis direction. .
