Description

Switch Pack Assembly for Cable Clusters of Network Switches and the Special Release Tool Assembly Thereof
Technology Field The present invention relates to the technical field of network switches, especially to the assembly structures for the plug and the release of cables of network switches, in particular to a switch pack assembly for cable clusters of network switches and the special release tool assembly thereof.
Background Technology
In the modern society, with the continuous development of science and technology, the contacts between people are becoming closer increasingly, and the constructions of communication infrastructure are becoming more perfect and progressive, so as to promote the communication process between people to be guaranteed. However, for network switches at the core position of the network, a small switch only has a few dozen of cable interfaces, while a large switch has hundreds or even thousands of cable interfaces, under such a situation, the intensive degree of cables on the switch can be imagined, and if one or one set of cables need to be plugged and pulled for debugging, it is very difficult and complex in the case of an unusual intensity of cables, if the manipulation is improper, it will affect the communication quality of other cable interfaces, and may even lead to wrong plug and pull, so as to result in communication failure and even communication paralysis, which would have great impacts on people's work.
In the existing technology, in order to solve the drawbacks caused by plugging and pulling a single cable on a network switch, people have carried out a variety of attempts, some people proposed the technical solution of grouping cables, and plugging and pulling each group as a whole, in which a group of neighboring cables having certain functions can be assembled into an overall structure, and then be plugged and pulled integrally, and there are mainly two types of solutions as following:
(1) The first solution is that a set of (normally 12) cables (usually connected with RJ45 standard interfaces) are assembled and fixed together with a simple frame and screws, then are plugged as a whole, but a drawing tool equipped specially is needed for the pull operation; this structure only has the function of plugging and pulling cables as a whole, and lacks the function of plugging and pulling one separate cable, at the same time the drawing tool equipped specially can not unlock specific sites, it can only press all cable snap-fit components down as a whole, i and all cables can not be pulled out completely until all of them are unlocked and released, therefore not only the operation is inconvenient, but also the assembled structure is oversized, causing the cost relatively high.
(2) The second solution is that a set of cables are assembled and fixed together through a specific structure, and it also has the function of plugging cables as a whole, no separate tool is needed to pull cables as a whole, while the unlocking and pulling out the cables as a whole is achieved by using the clamping structure arranged at its end directly, of course, this operation requires specific inner parts to cooperate, thus resulting in the overall structure of the device more complex, the cost relatively high, and inevitably the volume relatively large; at the same time, it also has the function of plugging and pulling one separate cable, but in the operation of plugging and pulling cables individually, it is necessary to use a specific operational tool to achieve the function, for in the maintenance process of the switch, the operation of replacing some cables individually will be conducted frequently, while the operation of plugging and pulling the cables integrally will be seldom conducted, unless in the processes of new installation, commissioning and replacement will it be possible to conduct such an operation, so the structure and function will cause inconvenience to users instead.
Disclosure of the Invention

Preferred Embodiments of the Invention
In order to understand the technical content of the present invention clearly, the present invention is further exemplified by reference to the following examples.
Please refer to Fig. 1 and Fig. 2, the switch pack assembly for cable clusters of network switches comprises a central framework 1 and two covers 2 arranged movably at two sides of the central framework 1, wherein several longitudinal parallel cable-oriented holding troughs 13 are arranged on the central framework 1.
Wherein the central framework 1 includes a central horizontal substrate 11, on two side surfaces of the central lateral substrate 11 both are arranged spacedly several longitudinal clapboards 12 perpendicular to the central lateral substrate 11 and extending along the longitudinal direction, and each of the cable-oriented holding troughs 13 is formed between adjacent longitudinal clapboards 12; meanwhile in the embodiment of the present invention, the longitudinal clapboards 12 arranged on the two side surfaces of the central lateral substrate 11 are mirror-image symmetrical about the central lateral substrate 11 as the symmetry axis, which makes the cable-oriented holding troughs 13 form two layers: the upper layer and the lower layer, and the number of the cable-oriented holding troughs 13 in each layer is at least 2, and can be 3, 4, 5, 6 or even more; and the width and the depth of the cable-oriented holding trough 13 should match the cable head to be assembled, for the RJ45 patch cord, because its size is an international standard, it is very easy to determine the size of the cable-oriented holding trough 13. in addition, the bottom of the RJ45 patch cord itself has a convex step, therefore in order to position and lock fixedly the cable with RJ45 patch cord longitudinally, at the corresponding position of the bottom of the cable-oriented holding trough 13 (i.e. on the central lateral substrate 11) can be arranged a position-limiting convex block 131, or a position-limiting looking hook, while at the front end of the cable-oriented holding trough 13 near to the central lateral substrate 11 is arranged a position-limiting baffle 132, so that when the cable with RJ45 patch cord is inserted into the cable-oriented holding trough 13, the convex step at the bottom of the patch cord and the position-limiting baffle 132 at the bottom of the front end of the cable-oriented holding trough 13 can be cooperated to prop against each other, and the rear end of the patch cord props against the position-limiting convex block 131, to achieve a very good longitudinal positioning effect, to prevent the cable from slipping backward and protruding forward.
Then please refer to Fig. 3 to Fig. 6, each of the covers 2 locks one of the side surfaces of the central framework 1 by sliding in the longitudinal direction, moreover the main body of the cover 2 covers on the cable-oriented holding troughs 13 to correspondingly form cable-oriented cavities four sides of each of which are closed, open windows 21 are arranged at the positions on the main body of the cover 2 corresponding to the front parts of at least one pair of cable-oriented cavities distributed by bilateral symmetry along the longitudinal central axis of the cover 2, and used mainly to allow that the cable snap-fit components 9 at the cable heads corresponding to the open windows 21 and the interfaces of the switch are locked each other fixedly, whereas other cable snap-fit components 9 at the cable heads above which there are no open windows 21 are compressed, therefore not only the switch pack assembly for cable clusters can be fixed firmly on the switch, but also the unlocking operation can be achieved by only pressing the locked cable snap-fit components 9 at the corresponding positions when the switch pack assembly for cable clusters is to be removed.
In order to obtain the fixation effect as good as possible, in the embodiment of the present invention, the open windows 21 on the main body of the cover 2 are arranged at the positions corresponding to the front parts of the cable-oriented cavities at two ends of the central framework 1, so that when the cover is assembled, only the cable snap-fit components 9 of four cables near to the two ends of the central framework 1 can be locked fixedly with the interfaces of the network switch, whereas correspondingly the cable snap-fit components 9 of the cables at other positions are compressed, then not only the above structure facilitates the plugging and pulling operations, but also when the cover 2 is removed, the cable snap-fit components 9 at the middle position compressed previously would rise up, and be locked fixedly and automatically with the interfaces of the network switch, therefore the backward movement of the cover 2 would not move the cables together to cause them to release from the network switch.
Meanwhile, between the cover 2 and at least one longitudinal clapboard 12 on the corresponding side of the central lateral substrate 11 is arranged a longitudinal sliding guide mechanism along which the cover 2 slides to and fro; in the embodiment of the present invention, the longitudinal sliding guide mechanism includes a longitudinal sliding guide rail 121 arranged on the top part of the longitudinal clapboard 12, of course a longitudinal sliding guide groove can be arranged here instead, and a longitudinal sliding guide groove 22 is also arranged on the corresponding site of the cover 2, of course a longitudinal sliding guide rail can be arranged correspondingly here instead, in such a case, the longitudinal sliding guide rail 121 slides to and fro in the longitudinal sliding guide groove 22, so as to achieve the reciprocating movement of the cover 2 relative to the central framework 1, to ensure that users can assemble the cover 2 conveniently and flexibly, and disassemble the cover 2 conveniently.

Additionally, between the cover 2 and at least one longitudinal clapboard 12 on the corresponding side of the central lateral substrate 11 is arranged a longitudinal movable snap-fit mechanism, which is used to allow that the cover 2 can be positioned and locked stably on the central framework 1, and would not be released when the whole switch pack assembly for cable clusters is plugged and pulled, in order to obtain a more stable positioning effect, the longitudinal movable snap-fit mechanisms can be arranged respectively on at least one pair of the longitudinal clapboards 12 distributed by bilateral symmetry along the longitudinal central axis of the cover 2, and in the embodiment of the present invention, the number of the longitudinal movable snap-fit mechanisms is 2 in general, and they are arranged respectively on two longitudinal clapboards 12 nearest to the longitudinal central axis of the cover 2.

Meanwhile, in order to make the guide function more precise and stable, and easier to use, the position-limiting guide mechanisms can be arranged respectively on the corresponding places of the cover 2 corresponding to at least one pair of the longitudinal clapboards 12 distributed by bilateral symmetry along the longitudinal central axis of the cover 2, and in the embodiment of the present invention, the position-limiting guide mechanisms are arranged respectively on the corresponding places of the cover 2 corresponding to the longitudinal clapboard 12 nearest to the longitudinal central axis of the cover 2 and the pair of the longitudinal clapboards 12 most far away from the longitudinal central axis of the cover 2.
Please refer to Fig. 3 to Fig. 6 again, at the rear end of the cover 2 are further arranged cable-oriented notches 27 corresponding to and cooperating with the cable-oriented cavities mentioned above respectively, and the bottom parts of the cable-oriented notches 27 prop directly against the rear part of the central lateral substrate 11 of the central framework 1 , so as to form together cable-oriented position-limiting holes, which are used mainly to restraint and position the rear parts of the cables, and prevent adjacent cables from twisting, so as to facilitate maintainers to manage cables and know the corresponding relationship of the cables and the interfaces of the network switch.
Then please refer to Fig. 7 to Fig. 11, in order to ensure that the switch pack assembly for cable clusters of network switches of the present invention still can be plugged and pulled integrally and conveniently when the cables are intensive and hands can not touch the cable snap-fit components 9, the present invention further provides a special release tool assembly 3 for pulling the above mentioned switch pack assembly for cable clusters integrally away from network switches, wherein the special release tool assembly 3 comprises a pair of clamping handles 31 the rear ends of which are hinged movably with each other, in the embodiment of the present invention, at the rear ends of the clamping handles 31 are all arranged hinged pivots 32, moreover the hinged pivots 32 on the clamping handles 31 are inserted spacedly and staggeredly into each other, and the central shaft holes 33 of them coincide with each other, and a hinge 4 is inserted into and fixed in the central shaft hole 33 of the hinged pivots 32, allowing the pair of the clamping handles 31 to be able to rotate around the hinged pivots 32, so as to open a certain angle according to actual needs, and clamp the above mentioned switch pack assembly for cable clusters very well
