Description

Technical Field

[0001] The utility model relates to the technical field of carrier communication equipment, in particular to a carrier communication equipment for electric energy meters with anti-loosening docking. Background Art

[0002] The electric energy meter, also known as the watt-hour meter, fire meter, and kilowatt-hour meter, is an instrument used to measure electric energy. Carrier communication is also called power line carrier communication. It couples the data to be transmitted to the power line through communication coupling for continued transmission, and samples and identifies the coupled communication data through related circuits.

[0003] For example, a docking anti-loosening electric energy meter carrier communication device with the authorization announcement number "CN219937514U" fixes the cable by enlarging the fixed block and the power connection board with anti-slip protrusions when connecting the cable, thereby increasing the contact area with the cable, reducing the probability of the cable loosening, and ensuring the stable operation of the device. However, the docking anti-loosening electric energy meter carrier communication device limits the cable by limiting the position of the spring clip. After limiting the thicker cable, when limiting the thinner cable again, the elastic force of the limiting spring clip is damaged, and the thinner cable cannot be limited, which easily causes the thinner cable to loosen and be damaged, requiring the operator to replace it, thereby increasing the work cost. At the same time, the docking anti-loosening electric energy meter carrier communication device disassembles the limiting base through the connecting piece. Since the operator needs to turn multiple screws during disassembly, it consumes more physical strength of the operator, thereby increasing the manual labor. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when limiting the cable by a limiting spring piece, after limiting the thicker cable, the thinner cable is limited again, the elastic force of the limiting spring piece is damaged, and the thinner cable cannot be limited, which easily causes the thinner cable to loosen and be damaged, and the operator needs to replace it, thereby increasing the work cost. At the same time, the electric energy meter carrier communication device with anti-loosening docking uses a connecting piece to disassemble the limiting base. During disassembly, the operator needs to turn multiple screws, which consumes more physical strength of the operator, thereby increasing the labor cost. Therefore, a kind of electric energy meter carrier communication device with anti-loosening docking is proposed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Preferably, the auxiliary fixing mechanism includes a first shell, the surface of the first shell is fixedly connected to the surface of the base, the slide groove processed on the first shell is slidably connected to the surface of the pull rod, the surface of the pull rod is fixedly connected to the surface of the cross bar, the cross bar is slidably connected to the sleeve through a through hole, the surface of the cross bar is fixedly connected to one end of the spring, the other end of the spring is fixedly connected to the inner wall of the sleeve, the surface of the sleeve is fixedly connected to the inner wall of the first shell, the cross bar passes through the first shell through the through hole, and the cross bar is slidably connected to the first shell through the through hole.

[0008] Preferably, the cross bar is slidably connected to the base via a through hole, and the end of the cross bar is tightly pressed against the surface of a groove processed on the protective top shell.

[0009] Preferably, the limiting mechanism includes a second shell, which is rotatably connected to the handlebar via a bearing, a stud is fixedly connected to the surface of the handlebar, the stud is rotatably connected to the second shell via a bearing, the stud is threadedly connected to two clamping plates, the two clamping plates are slidably connected to a slide groove processed on the fixed block, the surface of the fixed block is fixedly connected to the inner wall of the second shell, and the two clamping plates are slidably connected to the slide groove processed on the second shell.

[0010] Preferably, the second shell surface is fixedly connected to the protective top shell surface, and the base surface is provided with a plurality of heat dissipation holes.

[0011] The utility model proposes a carrier communication device for electric energy meters with anti-loosening docking, and the beneficial effect is that: through the cooperation of the clamping plate and the limiting mechanism, the rotation of the handle drives the double-headed stud to rotate, thereby driving the two clamping plates to move relative to each other along the slide groove processed on the fixed block, and at the same time, the two clamping plates slide relative to each other along the slide groove processed on the second shell, so that after limiting the thicker cable, the thinner cable can be limited again, and the thinner cable is not easy to loosen and cause damage, requiring the operator to replace it, thereby increasing the working cost.

[0012] Through the cooperation of the cross bar and the auxiliary fixing mechanism, the pull rod moves to the right, driving the cross bar to slide to the right along the through hole processed on the sleeve, compressing the spring.

[0024] See attached Figure 4 and attached Figure 6

[0025] The limiting mechanism 6 includes a second shell 601, which is rotatably connected to the turning handle 602 through a bearing. A stud 603 is fixedly connected to the surface of the turning handle 602. The stud 603 is rotatably connected to the second shell 601 through a bearing. The stud 603 is threadedly connected to two clamping plates 605. The two clamping plates 605 are slidably connected to the slide groove processed on the fixed block 604. The surface of the fixed block 604 is fixedly connected to the inner wall of the second shell 601. The two clamping plates 605 are slidably connected to the slide groove processed on the second shell 601. The rotation of the turning handle 602 drives the stud 603 to rotate, thereby driving the two clamping plates 605 to move relative to each other along the slide groove processed on the fixed block 604. At the same time, the two clamping plates 605 slide relative to each other along the slide groove processed on the second shell 601.

[0026] Working principle:

[0027] When installing the carrier communication equipment of the electric energy meter with loose connection:

[0028] Preparation process:

[0029] First, fix the base 1 on the wall through bolts and positioning holes, then install the main control circuit board 2 on the base 1, and then insert the protective top shell 4 along the sliding groove processed on the base 1.

[0030] Protective top shell fixing process:

[0031] First, the operator manually pulls the right pull rod 302 to the right, and the pull rod 302 moves to the right, driving the cross bar 303 to slide to the right along the through hole processed on the sleeve 304, compressing the spring 305. At the same time, the cross bar 303 slides to the right along the through hole processed on the first shell 301. Similarly, the left pull rod 302 is pulled to the left to move the left cross bar 303 to the left. When the ends of the two cross bars 303 are aligned with the axial positions of the grooves processed on both sides of the protective top shell 4, the operator slowly loosens the two pull rods 302. Through the elasticity of the spring 305, the surfaces of the two cross bars 303 are pressed against the inner walls of the grooves processed on the protective top shell 4, so that the protective top shell 4 can be quickly fixed without the operator consuming much physical strength, thereby saving manual labor.

[0032] Cable installation process:

[0033] First, pass the cable between the two clamping plates 605. The operator turns the handle 602 clockwise. The rotation of the handle 602 drives the double-headed stud 603 to rotate, thereby driving the two clamping plates 605 to move relative to each other along the slide groove processed on the fixed block 604. At the same time, the two clamping plates 605 slide relative to each other along the slide groove processed on the second shell 601. When the surfaces of the two clamping plates 605 are tightly combined with the surface of the cable, the operator stops turning the handle 602 and then fixes the cable. The clamping plate 605 can be selected according to the model of the cable to ensure that the cable will not loosen after being fixed, and will not cause damage to the cable, thereby reducing the working cost. Repeat the above operation to install multiple cables on the power terminal block 9. When the main control circuit board 2 is out of power, the main control circuit board 2 can be charged through the power socket 5.
