Description

Technical Field

[0001] This utility model relates to the field of patch panel technology, specifically to a patch panel for central control host circuits. Background Technology

[0002] In modern intelligent systems, the central control unit, as the core control device, needs to connect various terminal devices through patch panels to achieve signal transmission and system integration. Patch panels, as traditional line management equipment, use snap-fit ​​terminals to physically fix and electrically connect cables.

[0003] In practical use, existing patch panels often experience significant weight issues when the cables connecting to the patch panel interface (such as front-end sensor cables and rear-end host connection cables) are heavy. The continuous tensile force generated by the cable weight directly acts on the connection terminals. Furthermore, due to space constraints in the wiring environment, cables often need to bend during routing, resulting in radial stress that is transmitted along the connection point to the interface. Under long-term stress, this can easily lead to problems such as loosening of the connection terminals. Chinese Patent CN220359281U discloses a patch panel including a main body with several horizontally equidistant interfaces on the front wall and mounting plates fixedly installed on both the left and right side walls.

[0004] Regarding the disclosed technology, the protective structure used causes problems during cable installation. Because the cable needs to be pulled through the hole that fits the cable size, the protective structure is too close to the cable rack, which hinders the insertion and removal of the cable. In addition, the hole position is fixed, and it cannot be freely adapted to different models of patch panels, which is a defect in use. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a patch panel for central control unit circuitry, which solves the problem that the components protecting the cables on the patch panel hinder cable installation and cannot be adapted to different patch panel models.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a wiring rack for a central control host circuit, including a cable mounting rack, and further including a fixing clamp, a supporting crossbar, a sliding frame and a limiting plate. The number of the fixing clamp, supporting crossbar and sliding frame is two sets. The two sets of fixing clamps are located on the left and right sides of the cable mounting rack, and the two sets of supporting crossbars and sliding frames are located on the upper and lower sides of the cable mounting rack, respectively. The left and right ends of the supporting crossbar are slidably inserted into the cable mounting rack.

[0007] The sliding frame includes a sliding component and a pushing component. The sliding component is slidably installed inside the supporting crossbar, and the pushing component is disposed inside the sliding component. There are two sets of limiting plates, which are slidably installed on both sides inside the sliding component and connected to both ends of the pushing component.

[0008] The fixing fixture includes a sleeve plate and bolt fasteners. The surface of the sleeve plate has two symmetrical insertion holes, which are corresponding to the support crossbar. The surface of the sleeve plate is threaded with bolt fasteners. There are two sets of sleeve plates, and the two sets of sleeve plates are respectively set at the upper and lower ends of the bolt fastener surface.

[0009] The support crossbar includes a positioning plate and a pressure plate. The positioning plate is in contact with the surface of the cable mounting frame. A slot is provided on the side of the positioning plate away from the cable mounting frame and close to the sliding frame. The positioning plate and the pressure plate are fitted together.

[0010] The sliding component of the sliding frame includes a support base, a fixed plate, and a sliding sleeve. The fixed plate is fixedly installed on one end of the support base, and the fixed plate has locking teeth on the front and rear sides. The sliding sleeve is fixedly installed on the other end of the support base, and the sliding sleeve is arc-shaped.

[0011] The sliding frame pusher includes a guide crank and a spring. The two ends of the guide crank are connected to the inner walls of the front and rear sides of the sliding sleeve, respectively. The spring is slidably sleeved on the surface of the guide crank, and its two ends are connected to two sets of limiting plates, respectively.

[0012] The limiting plate includes a slider, a protective plate, and an insert plate. The slider is slidably installed inside the sliding component of the sliding frame. One end of the protective plate is connected to the end of the slider away from the sliding frame. The insert plate is fixedly installed on the side of the protective plate close to the sliding frame. The free end of the insert plate has a hole.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention uses a spring to push two sets of sliders, causing them to slide on the surface of a guide crank. The two sets of sliders slide in opposite directions, driving the protective plates located on the upper and lower sides of the cable mounting bracket to slide until they contact each other. This places the cable inside the groove of the protective plate, providing auxiliary support for the cable and applying a supporting force opposite to its own weight and bending stress, thus preventing the cable from loosening after long-term use. When installing the cable, simply pinch the lever on the protective plate to pull it away and insert or remove the cable. This protects the cable while preventing the mechanism from obstructing the installation process. By adjusting the engagement position of the locking teeth of the fixing plate and the locking groove of the positioning plate, the installation position of the sliding bracket on the surface of the support crossbar can be adjusted according to the different models of cable mounting brackets, the different locations of cable connections, and the different adjacent intervals. The fixing clamp presses on the support crossbar to fix the support crossbar and the sliding bracket to the surface of the cable mounting bracket. Excess length of the support crossbar can be cut off. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0023] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 6 The present invention will be further described below.

[0024] A wiring harness for a central control unit includes a cable mounting frame 1, a fixing clamp 2, a supporting crossbar 3, a sliding frame 4, and a limiting plate 5. There are two sets of fixing clamps 2, supporting crossbars 3, and sliding frames 4. The two sets of fixing clamps 2 are located on the left and right sides of the cable mounting frame 1, respectively. The two sets of supporting crossbars 3 and sliding frames 4 are located on the upper and lower sides of the cable mounting frame 1, respectively. The left and right ends of the supporting crossbars 3 are slidably inserted into the cable mounting frame 1. The sliding frame 4 includes a sliding component and a pushing component. The sliding component is slidably installed inside the supporting crossbar 3, and the pushing component is located inside the sliding component. There are two sets of limiting plates 5. The two sets of limiting plates 5 are slidably installed on the inner sides of the sliding component and connected to the two ends of the pushing component.

[0025] Specifically, the cable mounting bracket 1 is connected and fixed to the cable used by the central control host. The support crossbar 3 is fixed to the surface of the cable mounting bracket 1 by the fixing clamp 2, so that the support crossbar 3 limits and fixes the sliding bracket 4. The pusher of the sliding bracket 4 pushes the limiting plate 5 to slide inside the sliding member of the sliding bracket 4, so that the limiting plates 5 located on the upper and lower sides of the cable mounting bracket 1 seal and protect the upper and lower sides of the cable.

[0026] The fixing fixture 2 includes a sleeve plate 201 and a bolt fastener 202. The surface of the sleeve plate 201 has two symmetrical insertion holes, which are corresponding to the support crossbar 3. The bolt fastener 202 is threaded on the surface of the sleeve plate 201. There are two sets of sleeve plates 201, and the two sets of sleeve plates 201 are respectively set at the upper and lower ends of the surface of the bolt fastener 202.

[0027] Specifically, by rotating the bolt fastener 202, the two sets of sleeve plates 201 are driven to move in opposite directions, so that the sleeve plates 201 drive the support crossbars 3 on the upper and lower sides of the cable mounting frame 1 to be pressed tightly against its surface, thereby limiting and fixing the support crossbars 3 and the sliding frame 4.

[0028] The support crossbar 3 includes a positioning plate 301 and a pressure plate 302. The positioning plate 301 is in contact with the surface of the cable mounting frame 1. The positioning plate 301 has a slot on the side away from the cable mounting frame 1 and close to the sliding frame 4. The positioning plate 301 and the pressure plate 302 are in contact. There are two sets of positioning plates 301 and pressure plates 302, which are symmetrically arranged. The two sets of in contact positioning plates 301 and pressure plates 302 pass through two insertion holes of the sleeve plate 201 respectively.

[0029] Specifically, the positioning plate 301 blocks the slot of the pressure plate 302, pressing the sliding component of the sliding frame 4 tightly against the slot of the pressure plate 302, thereby limiting and fixing the position of the sliding frame 4 on the support crossbar 3.

[0030] The sliding component of the sliding frame 4 includes a support base 401, a fixing plate 402, and a sliding sleeve 403. The support base 401 has threaded holes on its left and right sides. The fixing plate 402 is fixedly installed on one end of the support base 401. The fixing plate 402 has locking teeth on its front and rear sides. The locking teeth of the fixing plate 402 are corresponding to the locking grooves of the positioning plate 301. The sliding sleeve 403 is fixedly installed on the other end of the support base 401. The sliding sleeve 403 is arc-shaped.

[0031] Specifically, by connecting the fixing plate 402 and the positioning plate 301, the position of the support base 401 on the support crossbar 3 is limited and fixed. The sliding sleeve 403 supports the limiting plate 5 to slide stably inside, so that the pusher can push the limiting plate 5 to move to both sides.

[0032] The pushing component of the sliding frame 4 includes a guide crank 404 and a spring 405. The two ends of the guide crank 404 are respectively connected to the inner walls of the front and rear sides of the sliding sleeve 403. The spring 405 is slidably sleeved on the surface of the guide crank 404, and its two ends are respectively connected to two sets of limiting plates 5.

[0033] Specifically, the guide crank 404 guides the sliding of the limiting plate 5 to make its movement more stable, and the spring 405 pushes the limiting plate 5 to slide on the surface of the guide crank 404.

[0034] The limiting plate 5 includes a slider 501, a protective plate 502, and an insert plate 503. The slider 501 is slidably installed inside the sliding sleeve 403. The slider 501 is slidably inserted into the guide crank 404. One side of the slider 501 is connected to the spring 405. One end of the protective plate 502 is connected to the end of the slider 501 away from the sliding frame 4. A paddle is installed on the top of one end of the protective plate 502. A groove is opened at the other end of the protective plate 502. The insert plate 503 is fixedly installed on the side of the protective plate 502 close to the sliding frame 4. A hole is opened at the free end of the insert plate 503, and the hole of the insert plate 503 is corresponding to the threaded hole of the support base 401.

[0035] Specifically, the slider 501 drives the protective plate 502 to slide, so that the groove of the protective plate 502 fits against the upper and lower sides of the cable. The hole of the insert plate 503 is aligned with the threaded hole of the support base 401, and a bolt can be passed through both to limit and fix the limiting plate 5.

[0036] In summary: When using this utility model, if the operator needs to install a patch panel and connect and fix the central control host circuit, adjust the number of sliding frames 4 according to the model of the cable mounting bracket 1 used. Insert the teeth of the fixing plate 402 into the slots of the positioning plate 301 to determine the position of the sliding frame 4. Place the positioning plate 301 and the pressure plate 302 together so that the positioning plate 301 and the sliding frame 4 are respectively attached to the upper and lower sides of the cable mounting bracket 1. Push the sleeve plate 201 onto both ends of the support crossbar 3. Insert the positioning plate 301 and the pressure plate 302 into the insertion holes of the sleeve plate 201. Tighten the bolt fastener 202 to drive the two sets of sleeve plates 201 to move in opposite directions, controlling the support crossbar 3 and the sliding frame 4 to be tightly attached to the upper and lower sides of the cable mounting bracket 1, completing the sliding frame installation. With the position of the movable frame 4 fixed, the groove of the protective plate 502 is aligned with the connection of the cable mounting bracket 1. When installing the cable, simply pinch the lever of the protective plate 502 and push the slider 501 to slide along the surface of the guide crank 404 to compress the spring 405, which allows for the insertion and removal of the cable. Releasing the lever allows the spring 405 to push the protective plate 502 to provide auxiliary support for the upper and lower sides of the cable. For lightweight cables with no bent connection, the spring force of the spring 405 on the protective plate 502 can be used to clamp the cable for a long time. For heavier cables with bent connection, bolts can be added through the holes of the insertion plate 503 and the threaded holes of the support base 401 to limit and fix the limit plate 5, ensuring that the device effectively supports the cable.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
