Description

Technical Field

[0001] This utility model relates to the field of network communication equipment technology, specifically a computer network junction box. Background Technology

[0002] A computer network is a digital telecommunications network that allows nodes to share resources. At the physical level, computer networks are used to connect different physical devices and transmit bit streams.

[0003] In practical applications, the network cable from the switch or router is not directly connected to the computer device. A junction box is usually installed at the end of the cable, and the computer device connects to the junction box via the network cable. This satisfies network connectivity while facilitating the repositioning of the computer device.

[0004] In existing technology, junction boxes typically contain terminal blocks for quick connection of network cables from routers or switches. These terminal blocks generally use notched metal punch-down clips to break the insulation of the wire cores. However, network cables are easily pulled accidentally, causing the wire cores to become loosely connected to the punch-down clips or detach from them, leading to signal weakening or disconnection and affecting network stability. Furthermore, when the wire cores are inserted into the punch-down clips, the pulling between the cores can cause the cable to shift and become misaligned. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a computer network junction box.

[0006] The technical solution of this utility model is:

[0007] A computer network junction box, comprising:

[0011] Preferably, the terminal block includes a base plate, and the top surface of the base plate is symmetrically provided with terminal blocks on the left and right sides, and the terminal blocks are provided with a plurality of wire-passing grooves running through them on the left and right sides.

[0012] Preferably, the wire slot is provided with a punch clamp, the punch clamp has an opening in the middle and an upward opening, and the bottom of the punch clamp passes through the base plate and the terminal block and is soldered to the PCB.

[0013] Preferably, the bottom surface of the cover plate is symmetrically provided with a locking block, the terminal block is inserted into the locking block, and a second wire-passing groove is provided on the locking block at a position corresponding to the wire-passing groove.

[0014] Preferably, the fastener includes an inner sleeve for insertion between the outermost insulation layer and the core of the cable, and an outer sleeve is threaded onto the outside of the inner sleeve for pressing the outermost insulation layer of the cable.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model utilizes the cooperation of an inner sleeve and an outer sleeve to clamp the outer insulation of the cable, thereby fixing the cable and terminal cover and preventing the cable from moving.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figure 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0029] A computer network junction box, comprising:

[0030] The protective shell 1 contains a wiring assembly 2. The wiring assembly 2 includes a PCB 21. Several connectors 22 are provided on the front of the top of the PCB 21. A set of wiring terminals 3 is provided behind each connector 22 and on the top surface of the PCB 21. A terminal cover 4 is snapped onto the top of the wiring terminal 3. The terminal cover 4 includes a cover plate 41. A fixing member is provided at the rear of the cover plate 41. The fixing member is used to fix the network cable.

[0031] Connector 22 uses a working network cable interface, and terminal 3 is used to connect the cable and transmit the signal from the cable to PCB 21. PCB 21 is used to transmit the signal to the corresponding connector 22.

[0032] The protective case 1 includes a bottom box 11, a top cover 12 is snapped onto the top of the bottom box 11, and a buckle 14 is provided on the bottom surface inside the bottom box 11. The PCB 21 is snapped and installed between the buckles 14.

[0033] The front side of the bottom box 11 has several openings extending upwards, the number of which is the same as the number of connectors 22.

[0034] When installing the wiring assembly 2, insert the end of the connector 22 into the front opening of the bottom box 11, ensuring that the PCB 21 is horizontal, and press it down into the clips 14.

[0035] The bottom box 11 has a partition 13 on the rear side inside. The partition 13 and the top cover 12 are connected by a wire groove 15 at the front and rear ends. The bottom box 11 has a wire hole 16 at the top and bottom ends.

[0036] The partition 13 abuts against the tail end of PCB21 to restrict the backward movement of PCB21.

[0037] Cables can be inserted into the bottom box 11 from below the cable pass-through hole 16, and then enter the top of the PCB 21 through the cable guide 15. Alternatively, they can enter the top of the PCB 21 from behind the bottom box 11, passing through the cable guide 15 of the partition 13 and the top cover 12.

[0038] The terminal block 3 includes a base plate 31, and the top surface of the base plate 31 is symmetrically provided with terminal blocks 32. The terminal blocks 32 are provided with several wire grooves 33 running through them on the left and right sides.

[0039] The base plate 31 and the terminal block 32 are made of plastic and molded as a single piece.

[0040] The base plate 31 is fixedly mounted on the top surface of the PCB 21 with screws. A sticker with the wiring instructions can be pasted on the top surface of the base plate 31, which is located between the terminal blocks 32.

[0041] The width of the thread groove 33 is slightly larger than the diameter of the wire core.

[0042] The wire pass-through groove 33 is equipped with a wire clip 34. The wire clip 34 has an opening in the middle and faces upward. The bottom of the wire clip 34 passes through the base plate 31 and the terminal block 32 and is soldered to the PCB 21.

[0043] The punch-down clamp 34 is made of metal and has a notch extending upwards through the center. The width of the notch on the inner side of the punch-down clamp 34 is the same as the diameter of the metal wire inside the core. When the core is inserted into the punch-down clamp 34, the insulation of the core is squeezed and broken by the punch-down clamp 34, allowing the internal metal wire to come into contact with the punch-down clamp 34.

[0044] The bottom surface of the cover plate 41 is symmetrically provided with a locking block 42, the terminal block 32 is inserted into the locking block 42, and a second wire groove 43 is provided on the locking block 42 at a position corresponding to the wire groove 33.

[0045] The terminal block 32 and the card block 42 are interference fit.

[0046] The width of the second threading groove 43 is slightly smaller than the width of the wire core and slightly smaller than the threading groove 33.

[0047] After the wire core is inserted into the second threading groove 43, it will remain in the second threading groove 43 due to friction.

[0048] The card block 42 has a wire pressing plate 44 inside. The wire pressing plate 44 is located directly above the second wire threading groove 43, and the end face of the wire pressing plate 44 is flush with the top surface of the second wire threading groove 43.

[0049] When the terminal block 32 is inserted into the clip 42, the wire clamp 44 can prevent the wire core from moving upward, thereby pressing the wire core into the punch clamp 34.

[0050] The fastener includes an inner sleeve 45, which is inserted between the outermost insulation layer and the core of the cable. An outer sleeve 46 is threaded onto the outside of the inner sleeve 45, which is used to press the outermost insulation layer of the cable.

[0051] The inner sleeve 45 is a cylindrical sleeve with a beveled outer side at the head of the inner sleeve 45. The bevel is inclined towards the axis of the inner sleeve 45 to facilitate the insertion of the inner sleeve 45 between the outermost insulation and the wire core.

[0052] During installation, first, slip the outer sleeve 46 onto the cable. Then, peel off a portion of the outermost insulation of the cable and insert the wire core into the inner sleeve 45. Finally, insert the inner sleeve 45 between the outermost insulation and the wire core. Thread the outer sleeve 46 and inner sleeve 45 together, causing the outer sleeve 46 to move towards the inner sleeve 45, compressing the outer insulation of the cable and securing it in place.

[0053] In this embodiment, when the operator uses this device, he / she opens the top cover 12 and removes the terminal cover 4.

[0054] Choose different wiring methods depending on the location of the junction box.

[0055] After the cable is inserted into the protective shell 1, a portion of the outermost insulation layer of the cable head is stripped off.

[0056] The outer sleeve 46 is fitted onto the cable, and then the wire core is inserted into the inner sleeve 45. The inner sleeve 45 is then inserted between the outermost insulation layer and the wire core. Finally, the outer sleeve 46 and the inner sleeve 45 are threaded together, causing the outer sleeve 46 to move towards the inner sleeve 45, compressing the outer insulation layer of the cable and securing the cable.

[0057] Insert the wire cores into the corresponding second threading slot 43 according to the wire sequence. Trim off any excess.

[0058] Keep the cover plate 41 horizontal, and then align the terminal block 32 with the locking block 42. Insert the terminal block 32 into the locking block 42 and press the cover plate 41 down. At this time, the wire clamping plate 44 will press the wire core into the wire clip 34.

[0059] During the wire core pressing process, the insulation of the wire core is squeezed by the wire clamp 34 and cracks, and the metal wire of the wire core comes into contact with the wire clamp 34 to complete the wire bonding.

[0060] Finally, replace the top cover 12 back in its original position.

[0061] When the cable is pulled, the pulling force is transmitted to the terminal cover 4, and there is no relative movement between the cable and the terminal cover 4.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
