Description

Technical Field

[0001] This invention relates to the field of wiring device technology, and more particularly to a signal line connection device. Background Technology

[0002] Safety monitoring is crucial for understanding building safety during both the construction and operation phases. In daily work, when a monitoring system malfunction is detected at the rear monitoring center, a laptop equipped with the monitoring system control software needs to be brought to the site for maintenance. The specific method involves first removing the two core wires of the original signal cable from the on-site monitoring equipment, then connecting the two core wires of one end of the provided signal cable to the monitoring equipment, and connecting the other end (via USB) to the laptop. Troubleshooting and maintenance are then performed using the monitoring system control software on the laptop. After the work is completed, the two core wires of the provided signal cable are removed from the monitoring equipment, and the two core wires of the original signal cable are reconnected. Over time, it has been found that disassembling and reassembling the signal cable is time-consuming, significantly impacting work efficiency. Furthermore, if the original signal cable is not properly reconnected, it is not easily detected on-site. If the monitoring system fails to collect data upon returning to the rear monitoring center, a second on-site inspection is required, which is not only time-consuming and labor-intensive but may also result in data loss. Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art. To this end, the embodiments of the present invention provide a signal line connection device, which saves on-site maintenance time of monitoring equipment and completely eliminates the problem that the monitoring system cannot collect data due to loose wiring in the original method.

[0004] This invention provides a signal line connection device, comprising: a fixed plate, a movable plate, a first guide rod, and a second guide rod. The fixed plate has a first sliding hole opened vertically, and elastic clamping plates for clamping terminal blocks are symmetrically fixed on the left and right sides of the fixed plate. The top of the movable plate protrudes forward and backward, and the longitudinal section of the movable plate is T-shaped. The movable plate is inserted into and passes through the first sliding hole, and the top of the movable plate is supported on the upper surface of the fixed plate. The movable plate slides horizontally within the first sliding hole. The first guide rod has a first end and a second end, and the first guide rod passes through the movable plate horizontally. The first guide rod is slidably connected to the movable plate, and the first end and the second end of the first guide rod are located on the front and rear sides of the first guide rod, respectively. The second end of the first guide rod is connected to the movable plate. A first tension spring is sleeved on a first guide rod. The second end of the first guide rod has a first external terminal for connecting a first core wire connector. The first end and the first external terminal of the first guide rod are electrically connected. A second guide rod has a first end and a second end. The second guide rod passes through a movable plate in a horizontal direction and is slidably connected to the movable plate. The first end and the second end of the second guide rod are located on the front and rear sides of the second guide rod, respectively. A second tension spring is connected between the second end of the second guide rod and the movable plate. The second tension spring is sleeved on the second guide rod. The second end of the second guide rod has a second external terminal for connecting a second core wire connector. The first end and the second external terminal of the second guide rod are electrically connected. The second guide rod is located directly below the first guide rod. The lengths of the first and second guide rods are equal.

[0005] Using the signal line connection device of the present invention, the built-in signal line for on-site maintenance of the monitoring equipment can be quickly connected without removing the original signal line of the monitoring equipment. This not only greatly saves on-site maintenance time, but also completely eliminates the problem of the monitoring system being unable to collect data due to loose wiring during the original method.

[0006] This invention, by setting a fixed plate and a movable plate, allows the movable plate to move horizontally along the fixed plate, facilitating the movement of the guide rod to the position of multiple sets of terminals arranged side by side on the terminal block frame of the monitoring equipment to be connected, thereby improving work efficiency and eliminating the need to remove the fixed plate from the monitoring equipment.

[0007] This invention uses elastic clamping plates fixedly connected to both sides of a fixed plate to ensure that the fixed plate is tightly clamped to both sides of the terminal block frame, facilitating the sequential testing of multiple sets of terminals on the terminal block frame.

[0008] This invention connects a tension spring to the guide rod, which on the one hand ensures that the guide rod and the terminal block are in close contact and electrically connected, and on the other hand, after one set of terminal blocks has been tested, the guide rod can be pulled outward to facilitate the movement of the movable plate to the terminal block to be tested.

[0009] In some embodiments, the fixing plate has a second sliding hole opened in the horizontal direction, the second sliding hole passing through the front end face and the rear end face of the fixing plate, the first sliding hole and the second sliding hole are connected, the first sliding hole and the second sliding hole have the same length in the horizontal direction, the first guide rod passes through the second sliding hole, and when the movable plate slides in the first sliding hole in the horizontal direction, it drives the first guide rod to slide in the second sliding hole in the horizontal direction.

[0010] In some embodiments, the signal line connection device further includes a connecting plate, which is fixedly connected to the first end of the first guide rod and the first end of the second guide rod. This allows the first and second guide rods to be pulled outwards simultaneously when the movable plate needs to be moved horizontally.

[0011] In some embodiments, a handle is fixedly connected to the outward-facing side of the connecting plate to facilitate pulling the connecting plate outward.

[0012] In some embodiments, both the first guide rod and the second guide rod are made of metal.

[0013] In some embodiments, the first guide rod includes a first rod body and a first end cap. The outer diameter of the first end cap is larger than the outer diameter of the first rod body. The first end cap is fixedly connected to the end of the first rod body. A first end of the first guide rod is located on the first rod body, and a second end of the first guide rod is located on the first end cap. A first tension spring is connected between the first end cap and a movable plate, and a first external connection is provided on the first end cap. The second guide rod includes a second rod body and a second end cap. The outer diameter of the second end cap is larger than the outer diameter of the second rod body. The second end cap is fixedly connected to the end of the second rod body. A first end of the second guide rod is located on the second rod body, and a second end of the second guide rod is located on the second end cap. A second tension spring is connected between the second end cap and the movable plate, and a second external connection is provided on the second end cap. By providing the end cap, it is convenient to connect the tension spring, thereby facilitating the extension and retraction of the guide rod at the terminal.

[0014] In some embodiments, the upper and lower ends of the connecting plate are fixedly connected to the first end cap and the second end cap, respectively.

[0015] In some embodiments, the first external end is a first conductive clip for clamping the first core wire connector, the first conductive clip being fixedly connected to the first end cap; the second external end is a second conductive clip for clamping the second core wire connector, the second conductive clip being fixedly connected to the second end cap. This provides a quick connection method between the core wire connector and the conductor rod, facilitating the rapid conductive connection of the core wire of the built-in signal line to the terminal block.

[0016] In some embodiments, the first external end is a first groove on the first end cap for inserting a first core wire connector, and a first bolt for tightening the external wire is screwed into the first groove in a direction perpendicular to the depth direction of the first groove; the second external end is a second groove on the second end cap for inserting a second core wire connector, and a second bolt for tightening the external wire is screwed into the second groove in a direction perpendicular to the depth direction of the second groove. Another quick connection method for the core wire connector and the guide rod is provided, facilitating the rapid conductive connection of the core wire of the built-in signal line to the terminal block.

[0017] In some embodiments, the first wire groove is formed on the side of the first end cap, and the first bolt is screwed into the first wire groove from the outer end of the first end cap. The second wire groove is formed on the side of the second end cap, and the second bolt is screwed into the second wire groove from the outer end of the second end cap. This prevents the core wire of the built-in signal line from repeatedly rubbing against the fixed plate during the translation of the movable plate, thus preventing wear. Attached Figure Description

Detailed Implementation

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The signal line connection device of the present invention will now be described with reference to the accompanying drawings.

[0031] like Figure 1-7 As shown in the figure, an embodiment of the present invention proposes a signal line connection device, including: a fixed plate 1, a movable plate, a first guide rod, and a second guide rod. The fixed plate 1 has a first sliding hole 13 opened in the vertical direction. Elastic clamping plates 11 for clamping terminal block brackets 22 are symmetrically fixed on the left and right sides of the fixed plate 1. The top of the movable plate protrudes forward and backward, and the longitudinal section of the movable plate is T-shaped. The movable plate is inserted into and passes through the first sliding hole 13. The top of the movable plate is supported on the upper end surface of the fixed plate 1, and the movable plate slides horizontally in the first sliding hole 13. The first guide rod has a first end and a second end. The first guide rod passes through the movable plate in the horizontal direction and is slidably connected to the movable plate. The first end and the second end of the first guide rod are respectively located on the front and rear sides of the first guide rod. The second end of the first guide rod is connected to the movable plate. A first tension spring 14 is connected to the first guide rod, and the first tension spring 14 is sleeved on the first guide rod. The second end of the first guide rod has a first external terminal for connecting the first core wire connector. The first end and the first external terminal of the first guide rod are electrically connected. The second guide rod has a first end and a second end. The second guide rod passes through the movable plate in a horizontal direction and is slidably connected to the movable plate. The first end and the second end of the second guide rod are located on the front and rear sides of the second guide rod, respectively. A second tension spring 17 is connected between the second end of the second guide rod and the movable plate. The second tension spring 17 is sleeved on the second guide rod. The second end of the second guide rod has a second external terminal for connecting the second core wire connector. The first end and the second external terminal of the second guide rod are electrically connected. The second guide rod is located directly below the first guide rod. The lengths of the first guide rod and the second guide rod are equal.

[0032] Using the signal line connection device of the present invention, the built-in signal line for on-site maintenance of the monitoring equipment can be quickly connected without removing the original signal line of the monitoring equipment. This not only greatly saves on-site maintenance time, but also completely eliminates the problem of the monitoring system being unable to collect data due to loose wiring during the original method.

[0033] The present invention sets up a fixed plate 1 and a movable plate, so that the movable plate can be moved horizontally along the fixed plate 1, which makes it easier for the guide rod to move to the position of multiple sets of terminals 21 arranged in parallel on the terminal block frame 22 of the monitoring equipment to be connected, thereby improving work efficiency and eliminating the need to remove the fixed plate 1 from the monitoring equipment.

[0034] The present invention uses elastic clamping plates 11 fixedly connected to both sides of the fixing plate 1, so that the fixing plate 1 can be tightly clamped to both sides of the terminal block frame 22, which facilitates the sequential detection of multiple sets of terminals 21 on the terminal block frame 22.

[0035] The present invention connects a tension spring to the guide rod, which on the one hand makes the guide rod fit tightly with the terminal 21 and make a conductive connection; on the other hand, when one set of terminal 21 has been tested, the guide rod can be pulled outward to facilitate the movement of the movable plate to the terminal 21 that needs to be tested.

[0036] Furthermore, the elastic clamping plate 11 is made of rubber, and the elastic restoring force of the rubber allows the fixing plate 1 to be tightly clamped to both sides of the terminal block bracket 22. The connection method between the elastic clamping plate 11 and the fixing plate 1 can be conventional fixing methods such as bolt fixing or strong adhesive bonding. The elastic clamping plate 11 and the fixing plate 1 are perpendicular to each other. When using the elastic clamping plate 11, the elastic clamping plates 11 on both sides are opened outwards, the positions of the guide rod and the terminal block 21 are aligned, and then the elastic clamping plates 11 on both sides of the terminal block bracket 22 are placed. The elastic clamping plates 11 are then released. Due to the elasticity of the elastic clamping plates 11, the two elastic clamping plates 11 tightly clamp the terminal block bracket 22.

[0037] Furthermore, the fixing plate 1 is a rectangular plate with its length direction being horizontal, and the elastic clamping plate 11 is fixedly connected to both sides of the fixing plate 1 in the length direction. The first sliding hole 13 is a rectangular hole.

[0038] Furthermore, the first sliding hole 13 penetrates through the upper and lower end faces of the fixed plate 1. The movable plate includes an integrally formed plate body 7 and an end head 4. The end head 4 is located at the top of the plate body 7 and is used to prevent the movable plate from falling out of the first sliding hole 13 of the fixed plate 1, thus serving as a sliding limit. The length of the end head 4 is equal to the width of the movable plate, the width of the end head 4 is greater than the thickness of the movable plate, and the lower end face of the end head 4 slides in fit with the upper end face of the fixed plate 1.

[0039] Furthermore, the distance between the front inner wall and the rear inner wall of the first sliding hole 13 is slightly greater than the thickness of the plate 7, and the width of the end 4 is greater than the distance between the front inner wall and the rear inner wall of the first sliding hole 13, to prevent the movable plate from falling off the first sliding hole 13 of the fixed plate 1.

[0040] Furthermore, the first and second guide rods have identical structures and are parallel to each other. The first guide rod is located at the upper center of the movable plate, and the second guide rod is located at the lower center of the movable plate. Both the first and second guide rods have circular longitudinal sections. The distance between the first and second guide rods is equal to the distance between two terminals 21 in the same group on the terminal block bracket 22, so that when the movable plate moves to a position where a group of terminals 21 overlaps, the first and second guide rods can make close contact with the two terminals 21 in that group and achieve conductive connection.

[0041] Furthermore, both the fixed plate 1 and the movable plate are made of non-metallic materials to prevent leakage when external core wires are connected, such as rigid plastics and polytetrafluoroethylene.

[0042] In some embodiments, the fixed plate 1 has a second sliding hole 2 opened in the horizontal direction, the second sliding hole 2 passing through the front end face and the rear end face of the fixed plate 1. The first sliding hole 13 is connected to the second sliding hole 2, and the lengths of the first sliding hole 13 and the second sliding hole 2 are equal in the horizontal direction. The first guide rod passes through the second sliding hole 2. When the movable plate slides in the first sliding hole 13 in the horizontal direction, it drives the first guide rod to slide in the second sliding hole 2 in the horizontal direction. This makes the overall force on the movable plate more balanced.

[0043] Furthermore, the second sliding hole 2 is a rectangular hole, and the longitudinal sections of the first sliding hole 13 and the second sliding hole 2 form a cross shape. The width of the second sliding hole 2 is slightly larger than the maximum outer diameter of the first guide rod. This allows the first guide rod to move horizontally along the second sliding hole 2, as well as extend and retract axially.

[0044] In some embodiments, the signal line connection device further includes a connecting plate 6, which is fixedly connected to the first end of the first guide rod and the first end of the second guide rod. When it is necessary to move the movable plate, it is convenient to pull the first guide rod and the second guide rod outward simultaneously.

[0045] Furthermore, the connecting plate 6 is fixedly connected to the first guide rod and the second guide rod by bolting or welding. After the connecting plate 6 is fixedly connected, space must be reserved on the first guide rod and the second guide rod for the first external connection end and the second external connection end. The connecting plate 6 is located on the outside of the fixing plate 1.

[0046] In some embodiments, a handle 8 is fixedly connected to the outward side of the connecting plate 6. This facilitates pulling the connecting plate 6 outward.

[0047] Furthermore, the handle 8 is located in the middle of the connecting plate 6 to balance the forces on the first guide rod and the second guide rod.

[0048] In some embodiments, both the first and second guide rods are made of metal. Since metal is a conductive material, a conductive connection can be formed by connecting the core wire 15 to the first and second guide rods.

[0049] Furthermore, the first and second conductor rods can be made of conventional conductive metals such as stainless steel and copper.

[0050] In some embodiments, the first guide rod includes a first rod body 12 and a first end cap 5. The outer diameter of the first end cap 5 is larger than the outer diameter of the first rod body 12. The first end cap 5 is fixedly connected to the end of the first rod body 12. The first end of the first guide rod is located on the first rod body 12, and the second end of the first guide rod is located on the first end cap 5. A first tension spring 14 is connected between the first end cap 5 and the movable plate, and a first external connection is provided on the first end cap 5. The second guide rod includes a second rod body 16 and a second end cap 9. The outer diameter of the second end cap 9 is larger than the outer diameter of the second rod body 16. The second end cap 9 is fixedly connected to the end of the second rod body 16. The first end of the second guide rod is located on the second rod body 16, and the second end of the second guide rod is located on the second end cap 9. A second tension spring 17 is connected between the second end cap 9 and the movable plate, and a second external connection is provided on the second end cap 9. By providing the end cap, it is convenient to connect the tension spring, thereby facilitating the extension and retraction of the guide rod at the terminal 21.

[0051] Furthermore, the longitudinal sections of both the first and second guide rods are flat T-shaped, similar to the structure of a bolt. The first end cap 5 and the second end cap 9 are both disc-shaped structures, and the first rod body 12 and the second rod body 16 are both cylindrical structures. The first rod body 12 and the first end cap 5 are integrally formed, as are the second rod body 16 and the second end cap 9. The axis of the first rod body 12 is collinear with the axis of the first end cap 5, and the axis of the second rod body 16 is collinear with the axis of the second end cap 9. The first tension spring 14 is welded to both the movable plate and the first end cap 5, and the second tension spring 17 is also welded to both the movable plate and the second end cap 9.

[0052] In some embodiments, the upper and lower ends of the connecting plate 6 are fixedly connected to the first end cap 5 and the second end cap 9, respectively.

[0053] Furthermore, after the connecting plate 6 is fixedly connected, space should be reserved on the first end cap 5 and the second end cap 9 for the first external end and the second external end.

[0054] like Figure 7As shown, in some embodiments, the first external end is a first conductive clip 19 for clamping the first core wire connector, and the first conductive clip 19 is fixedly connected to the first end cap 5. The second external end is a second conductive clip 20 for clamping the second core wire connector, and the second conductive clip 20 is fixedly connected to the second end cap 9. This provides a quick connection method between the core wire connector and the conductor rod. The conductive clip can directly clamp the core wire connector, facilitating a quick conductive connection of the core wire 15 of the built-in signal line to the terminal block 21.

[0055] Furthermore, the first conductive clip 19 is electrically connected to the first end cap 5 by welding. When installing the first conductive clip 19, care should be taken to ensure that the pressing part faces outward from the first end cap 5 to facilitate manual release of the first conductive clip 19. The second conductive clip 20 is electrically connected to the second end cap 9 by welding. When installing the second conductive clip 20, care should be taken to ensure that the pressing part faces outward from the second end cap 9 to facilitate manual release of the second conductive clip 20.

[0056] In some embodiments, the first external end is a first groove 18 formed on the first end cap 5 for inserting a first core wire connector, and a first bolt 3 for tightening the external wire is screwed into the first groove 18 in a direction perpendicular to the depth direction of the first groove 18; the second external end is a second groove formed on the second end cap 9 for inserting a second core wire connector, and a second bolt 10 for tightening the external wire is screwed into the second groove in a direction perpendicular to the depth direction of the second groove. Another quick connection method between the core wire connector and the guide rod is provided, facilitating the rapid conductive connection of the core wire 15 of the built-in signal line to the terminal block 21.

[0057] In some embodiments, a first wire groove 18 is formed on the side of the first end cap 5, and a first bolt 3 is screwed into the first wire groove 18 from the outer end of the first end cap 5. A second wire groove is formed on the side of the second end cap 9, and a second bolt 10 is screwed into the second wire groove from the outer end of the second end cap 9. This prevents the core wire 15 of the built-in signal line from repeatedly rubbing against the fixed plate 1 during the translation of the movable plate, thus preventing wear.

[0058] The present application will be further illustrated by specific embodiments below.

[0059] Example 1

[0060] like Figure 1-6 As shown, in this embodiment, the first external end is the first wire groove 18 and the first bolt 3, and the second external end is the second wire groove and the second bolt 10.

[0061] When performing on-site maintenance of the monitoring equipment, first use the first bolt 3 to tighten one core wire 15 of the built-in signal cable into the first wire hole of the first guide rod. Connect the other core wire 15 of the signal cable to the second guide rod in the same way. Then, move the end 4 to move the movable plate to the position of one of the sets of terminals 21 that need to be tested, aligning the first and second guide rods with the two terminals 21 of that set. Secure the fixing plate 1 tightly to both sides of the terminal frame 22 using the elastic clamping plates 11 on both sides, ensuring that the first and second guide rods abut against the two terminals 21 of that set. Connect the USB interface at the other end of the built-in signal cable to a laptop computer. Troubleshooting and maintenance can then be performed through the monitoring system control software on the laptop. After one set of tests is completed, pull the handle 8 to pull the first and second guide rods outwards, detaching them from the two terminals 21 that have been tested. Then, move the end 4 to move the movable plate to the position of the next set of terminals 21 that need to be tested, and repeat the above process. After all the terminals 21 have been tested, the fixing plate 1 can be removed from the terminal bracket 22.

[0062] Example 2

[0063] like Figure 7 As shown, in this embodiment, the first external terminal is the first conductive clip 19, and the second external terminal is the second conductive clip 20.

[0064] When performing on-site maintenance of the monitoring equipment, use the first conductive clamp 19 and the second conductive clamp 20 to clamp the two core wires 15 of the built-in signal line, respectively. The rest of the process is the same as in Example 1.
