Description

Technical Field

[0001] The invention belongs to the technical field of switches, in particular to a multi-port switch with a wire harness protection structure. Background Art

[0002] Multi-port switches usually have multiple network interfaces for connecting multiple devices to achieve data exchange and communication. These interfaces can be RJ45 Ethernet ports, fiber optic ports, etc. to meet the connection requirements of different devices. Multi-port switches are widely used in enterprises, schools, homes and other places, and are important equipment for building a network environment.

[0003] The working principle of a multi-port switch is mainly based on link layer data processing. The switch receives and sends data packets through its various ports and forwards them according to the destination address of the data packet. Specifically, after receiving a data packet, the switch will first check its destination MAC address, and then forward the data packet to the corresponding port according to the internal forwarding table.

[0004] In the working process of the switch, the wiring harness plays a vital role. However, the wiring harness is also easily disturbed and damaged by the external environment, especially the position where the network cable crystal head contacts the network cable. The gravity problem will cause the bending angle between the wiring harness and the crystal head to be too large. At the same time, the wiring harness will pull the crystal head. Long-term pulling will easily cause the internal breakage of the wiring harness, thereby affecting the normal transmission of the signal. Therefore, a multi-port switch with a wiring harness protection structure is proposed to address the above problems. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Specific examples are given below.

[0032] See also Figure 1 - Figure 8 The present invention provides a multi-port switch with a harness protection structure, comprising a switch body 1 and a fixing component, wherein the side wall of the switch body 1 is provided with a plurality of connection ports; the side wall of the switch body 1 is connected to the fixing component; the side wall of the fixing component is connected to a first fixing box 11; the inner side wall of the first fixing box 11 is in sliding contact with a first connecting plate 12; a plurality of support rods 13 are fixedly connected to the top of the outer side wall of the first connecting plate 12; a fixing plate 14 is fixedly connected to the top of the outer side wall of the support rod 13; a pair of first limiting strips 15 are fixedly connected to the top of the outer side wall of the fixing plate 14; a plurality of first springs 16 are fixedly connected to the side wall of the fixing plate 14; an extrusion plate 17 is fixedly connected to the side wall of the first spring 16; the extrusion plate 17 is arranged as a pair; a connecting groove 18 is opened inside the extrusion plate 17; the first limiting strip 15 is in sliding contact with the connecting groove 18; the fixing plate 14 and the connection port are on the same horizontal line. When the device is working, first connect the network cable to the switch body 1, and then press the network cable down from above the squeezing plate 17. At this time, the first spring 16 will be squeezed and contracted. When the network cable is located between the two squeezing plates 17, the first spring 16 will push the squeezing plate 17 to squeeze the network cable to a certain extent, align the first connecting plate 12 connected with the network cable with the corresponding notch of the first fixing box 11, keep the first connecting plate 12 stationary, slide the first fixing box 11 to connect with the first connecting plate 12, and then install the first fixing box 11 on the side wall of the switch body 1 through the fixing assembly. At this time, the network cable and the port are in a horizontal state. By setting the squeezing plate 17 and the first spring 16, the device can always provide a certain clamping force to the network cable from both sides, so that the wire harness and the connection port always maintain a certain angle, reducing the situation where the wire harness is broken internally due to excessive bending angle at the network cable connection.

[0033] Further, such as Figure 1 , Figure 4 , Figure 6 and Figure 8As shown, a second fixing box 2 is fixedly connected to the top of the outer side wall of the first fixing box 11; a second connecting plate 21 is slidably contacted to the inner side wall of the second fixing box 2; a plurality of second springs 22 are fixedly connected to the bottom of the outer side wall of the second connecting plate 21; an auxiliary plate 23 is fixedly connected to the bottom of the outer side wall of the second spring 22; a first limiting plate 24 is fixedly connected to the bottom of the outer side wall of the auxiliary plate 23; a pair of second limiting strips 25 are slidably contacted to the side wall of the second fixing box 2; a contact block 26 is fixedly connected to the side wall of the second limiting strip 25; and the second limiting strip 25 is in contact with the second connecting plate 21. When the device is working, the first limit plate 24 is inserted from the top of the first fixing box 11, the second connecting plate 21 is inserted into the second fixing box 2, and then the second limit strips 25 on both sides are inserted into the second fixing box 2 and the second connecting plate 21. At this time, the second spring 22 will push the first limit plate 24 to contact the wiring harness, and when the second connecting plate 21 moves upward, due to the angle problem of the scale groove 5, the scale groove 5 will limit the upward movement of the second connecting plate 21, and the second connecting plate 21 is fixed. When removing the second connecting plate 21, first take out the second limit strips 25 on both sides, so that the second connecting plate 21 can slide upward normally. By setting the first limit plate 24 and the second spring 22, the stability of the wiring harness during use is further increased, and the situation where the network cable is accidentally pulled and touched and the network cable is pulled out of the device is reduced.

[0034] Further, such as Figure 3 As shown, a slide column 3 is in sliding contact inside the first fixing box 11; a connecting buckle 31 is fixedly connected to one end of the slide column 3; a limiting block 34 is fixedly connected to the other end; a third spring 32 is fixedly connected to the side wall of the connecting buckle 31; the third spring 32 is fixedly connected to the switch body 1; a pair of sliding grooves 33 are opened inside the first fixing box 11; the limiting block 34 is in contact with the sliding grooves 33; the limiting block 34 is in contact with the first connecting plate 12. When the equipment is working, the first fixing box 11 slides and contacts with the first connecting plate 12, at this time the limit block 34 will be squeezed, the limit block 34 will slide along the slide slot 33, and the third spring 32 will be stretched. When the first fixing box 11 is completely in contact with the first connecting plate 12, the third spring 32 will push the connecting buckle 31 to reset, thereby causing the slide slot 33 to slide. At this time, the limit block 34 will contact the notch of the side wall of the first connecting plate 12, so that the limit block 34 is in contact with the first connecting plate 12. At this time, the first connecting plate 12 cannot be separated from the first fixing box 11. When the equipment needs to be dismantled, the connecting buckle 31 is pulled to separate the limit block 34 from the first connecting plate 12. Through the set limit block 34 and the third spring 32, the staff can quickly and conveniently fix the first connecting plate 12, reduce the situation where the first connecting plate 12 slides and pulls the wiring harness when the equipment is working, and increase the protection of the wiring harness.

[0035] Further, such as Figure 1 and Figure 6As shown, the fixing assembly includes a second limiting plate 4, a first contact groove 41, a fixing bolt 42, and a thread groove 43; a pair of second limiting plates 4 are fixedly connected to the side wall of the switch body 1; a pair of first contact grooves 41 are opened on the side wall of the first fixing box 11; the first contact groove 41 is in sliding contact with the second limiting plate 4; a plurality of thread grooves 43 are opened on the side wall of the second limiting plate 4; a pair of fixing bolts 42 are bolted to the side wall of the first fixing box 11; the fixing bolts 42 are in contact with the thread groove 43. When the device is working, the first contact groove 41 is aligned with the second limiting plate 4, and the first fixing box 11 can be slid at this time. When the first fixing box 11 needs to be fixed, the fixing bolt 42 is passed through the first fixing box 11 and connected with the thread groove 43. At this time, the first fixing box 11 is bolted to the side wall of the switch body 1. The fixing bolts 42 and the thread groove 43 are set to further increase the stability of the connection between the first fixing box 11 and the switch body 1, and reduce the situation that the first fixing box 11 is separated from the switch body 1 when the device is working.

[0036] Further, such as Figure 1 As shown, the side wall of the switch body 1 is provided with a pair of scale grooves 5; the scale grooves 5 are arranged above the second limit plate 4; the scale grooves 5 are in contact with the first fixing box 11. When the device is working, the first fixing box 11 will slide, and the staff can understand the length of the first fixing box 11 leaking out by observing the scale grooves 5. The provided scale grooves 5 facilitate the staff to record the data after the device is adjusted, and facilitate the staff to use the device.

[0037] Further, such as Figure 1 and Figure 5 As shown, a handle 6 is fixedly connected to the side wall of the first connecting plate 12; a second contact groove 61 is provided on the side wall of the first connecting plate 12. When the equipment needs to be removed, the staff member pinches the handle 6 and then slides the first fixing box 11 to be separated from the first connecting plate 12. The handle 6 and the second contact groove 61 can increase the friction between the staff member and the first connecting plate 12, making it easier for the staff member to remove the equipment and reducing the probability that the first connecting plate 12 moves with the first fixing box 11 and stretches the network cable.

[0038] Further, such as Figure 2 As shown, a pair of reinforcing plates 7 are fixedly connected to the side walls of the support rod 13; the reinforcing plates 7 are fixedly connected to the first connecting plate 12. When the device is working, the support rod 13 plays a supporting role, and the reinforcing plates 7 can increase the stability of the support rod 13 when working. By setting the reinforcing plates 7, the bending and breaking of the support rod 13 when the device is used for a long time is reduced, thereby reducing the failure rate of the device.

[0039] Further, such as Figure 3As shown, a plurality of balls 8 are arranged inside the first fixing box 11; the balls 8 rotate inside the switch body 1; the balls 8 cannot be separated from the first fixing box 11; the balls 8 are in contact with the first connecting plate 12. When the device is working, the balls 8 can convert the sliding friction between the first fixing box 11 and the first connecting plate 12 into rolling friction. The friction between the first fixing box 11 and the first connecting plate 12 is reduced by the arranged balls 8, so that the first fixing box 11 and the first connecting plate 12 can slide together.

[0040] Further, such as Figure 1 As shown, the first limit plate 24 is made of rubber. When the device is working, the first limit plate 24 will squeeze the network cable to a certain extent from above. By setting the first limit plate 24 to be made of rubber, the probability of the first limit plate 24 crushing the network cable is reduced.

[0041] Working principle: When the device is working, first connect the network cable to the switch body 1, and then press the network cable from above the squeezing plate 17. At this time, the first spring 16 will be squeezed and contracted. When the network cable is between the two squeezing plates 17, the first spring 16 will push the squeezing plate 17 to squeeze the network cable to a certain extent, align the first connecting plate 12 connected with the network cable with the corresponding notch of the first fixing box 11, keep the first connecting plate 12 immobile, slide the first fixing box 11 to connect with the first connecting plate 12, and then install the first fixing box 11 on the side wall of the switch body 1 through the fixing assembly. At this time, the network cable and the port are in a horizontal state. By setting the squeezing plate 17 and the first spring 16, the device can always provide a certain clamping force on the network cable from both sides. The holding force makes the wiring harness and the connection port always maintain a certain angle, reduces the situation that the wiring harness is broken due to the excessive bending angle of the network cable connection. When the equipment is working, the first limit plate 24 is inserted from the top of the first fixing box 11, the second connecting plate 21 is inserted into the second fixing box 2, and then the second limit strips 25 on both sides are inserted into the second fixing box 2 and the second connecting plate 21. At this time, the second spring 22 will push the first limit plate 24 to contact with the wiring harness, and when the second connecting plate 21 moves upward, due to the angle problem of the scale groove 5, the scale groove 5 will limit the second connecting plate 21 from moving upward, and the second connecting plate 21 is fixed. When removing the second connecting plate 21, first take out the second limit strips 25 on both sides, so that the second connecting plate 21 can be The plate 21 slides upward normally, and the first limit plate 24 and the second spring 22 are provided to further increase the stability of the wiring harness when in use, and reduce the situation where the network cable is detached from the device due to pulling when it is accidentally pulled and touched. When the device is working, the first fixed box 11 slides and contacts the first connecting plate 12. At this time, the limit block 34 will be squeezed, and the limit block 34 will slide along the slide groove 33, and the third spring 32 will be stretched. When the first fixed box 11 is completely in contact with the first connecting plate 12, the third spring 32 will push the connecting buckle 31 to reset, thereby causing the slide groove 33 to slide. At this time, the limit block 34 will contact the notch on the side wall of the first connecting plate 12, so that the limit block 34 is in contact with the first connecting plate 12. At this time, the first connecting plate 12 has no The first fixing box 11 can be separated from the first fixing box 11. When the device needs to be removed, the connecting buckle 31 can be pulled to separate the limiting block 34 from the first connecting plate 12. The limiting block 34 and the third spring 32 are set, so that the staff can quickly and conveniently fix the first connecting plate 12, thereby reducing the situation where the first connecting plate 12 slides and pulls the wiring harness when the device is working, thereby increasing the protection of the wiring harness. When the device is working, the first contact groove 41 is aligned with the second limiting plate 4, and the first fixing box 11 can be slid at this time. When the first fixing box 11 needs to be fixed, the fixing bolt 42 is passed through the first fixing box 11 and connected with the thread groove 43. At this time, the first fixing box 11 is bolted to the side wall of the switch body 1, and the fixing bolt 42 and the thread groove 43 are set.The stability of the connection between the first fixing box 11 and the switch body 1 is further increased, and the situation where the first fixing box 11 is separated from the switch body 1 when the device is working is reduced. When the device is working, the first fixing box 11 will slide, and the staff can understand the length of the leakage of the first fixing box 11 by observing the scale groove 5. The set scale groove 5 is convenient for the staff to record the data after the device is adjusted, and it is convenient for the staff to use the device. When the device needs to be removed, the staff pinches the handle 6 and then slides the first fixing box 11 to separate from the first connecting plate 12. The handle 6 and the second contact groove 61 are set to increase the friction between the staff and the first connecting plate 12, which is convenient for the staff to remove the device and reduces the friction between the first connecting plate 12 and the first fixing box 11 when it moves. The probability of stretching the network cable with movement. When the device is working, the support rod 13 plays a supporting role. The reinforcing plate 7 can increase the stability of the support rod 13 when it is working. By setting the reinforcing plate 7, the bending and breaking of the support rod 13 when the device is used for a long time is reduced, and the failure rate of the device is reduced. When the device is working, the ball 8 can convert the sliding friction between the first fixed box 11 and the first connecting plate 12 into rolling friction. The friction between the first fixed box 11 and the first connecting plate 12 is reduced by the set ball 8, which facilitates the sliding cooperation between the first fixed box 11 and the first connecting plate 12. When the device is working, the first limiting plate 24 will squeeze the network cable to a certain extent from the top. By setting the first limiting plate 24 to be made of rubber material, the probability of the first limiting plate 24 crushing the network cable is reduced.
