Description

Technical Field

[0001] The present application relates to the technical field of low-voltage wiring devices, and in particular to a line metering wiring device. Background Art

[0002] A line metering wiring device refers to a device or component specially designed to safely, accurately and conveniently connect electric energy metering equipment (mainly electric energy meters) to the power line under test. It allows workers to safely install, replace, calibrate or maintain electric energy meters under live conditions without affecting the operation of the main line or causing the risk of electric shock.

[0003] Traditional wiring devices often use crimping wiring. When wiring, the ends of the wires need to be stripped first, and then the exposed ends of the wires are inserted into the terminal blocks. The wires are fixed inside the terminal blocks by vertically pressing down bolts to electrically connect the wires to the terminal blocks. Therefore, workers need to carry special wire stripping tools with them and have certain work experience to ensure that the wire cores are not damaged when stripping and that the length of the stripped insulation is appropriate. When there are many lines, the stripping process is more cumbersome, which will bring inconvenience to the workers. Utility Model Content

[0019] Based on this, in order to improve the technical problem in the related art that the wires need to be stripped when wiring the wiring device, which brings inconvenience to the staff, the embodiment of the present application provides the following solution.

[0020] The following combination Figure 1-Figure 5 This application is described in further detail.

[0021] This embodiment discloses a line metering wiring device: it includes a housing 1 and a puncture connection assembly 2, the housing 1 is symmetrically provided with a threading hole 11 and a puncture hole 12, the threading hole 11 is connected to the puncture hole 12, the axis of the threading hole 11 is perpendicular to the axis of the puncture hole 12 and is biased to one side of the axis of the puncture hole 12, the puncture connection assembly 2 includes a puncture screw 21 and a connector, the tip of the puncture screw 21 is conical, the main body of the puncture screw 21 is inserted into the puncture hole 12, the puncture screw 21 is threadedly connected to the housing 1, and the connector is provided on the housing 1 for electrically connecting the corresponding puncture screws 21 on both sides of the housing 1.

[0022] As can be seen from the above, the embodiment of the present application provides a line metering wiring device, in which the puncture screw 21 is made of conductive material. When wiring, the end of the wire is inserted into the wire threading hole 11. After the end of the wire contacts the bottom of the wire threading hole 11, the puncture screw 21 is twisted to move it toward the inside of the puncture hole 12. The tip of the puncture screw 21 pierces one side of the wire's epidermis and contacts the wire core. Then, the puncture screw 21 is continued to be twisted. Since the tip of the puncture screw 21 is conical, the tip of the puncture screw 21 continues to be inserted into the wire and gradually presses the wire core of the puncture screw 21, and the wire is gradually pressed in Inside the threading hole 11, after tightening the puncture screw 21, the tip of the puncture screw 21 is tightly in contact with the wire core to form an electrical connection. At the same time, the wire is pressed and fixed inside the threading hole 11 by the puncture screw 21. According to this step, each wire is connected to the corresponding threading hole 11. The two puncture screws 21 corresponding to the two sides of the shell 1 are electrically connected through the connector, and are respectively connected to the main line and the metering line, thereby completing the connection between the main line and the metering line; when wiring, the staff does not need to strip the end of the wire, which can facilitate the staff to use the wiring device.

[0023] In some embodiments, please refer to Figure 3 and Figure 4 The puncture screw 21 includes a connecting portion 211 and a puncture portion 212 . The connecting portion 211 and the puncture portion 212 are integrally formed. The puncture portion 212 is conical. The connecting portion 211 is threadedly connected to the housing 1 .

[0024] With this arrangement, the outer circumference of the connecting portion 211 is provided with threads and is threadedly connected to the housing 1 . When the connecting portion 211 is screwed, the housing 1 pushes the connecting portion 211 to move through the threads and drives the puncture portion 212 to approach and puncture the guidewire.

[0025] Optionally, in some embodiments, see Figures 2 to 4 The connecting part includes a threaded sleeve 22, which is fixedly mounted on the shell 1 and coaxial with the puncture hole 12. The puncture screw 21 passes through the inside of the threaded sleeve 22. The connecting part 211 is threadedly connected to the threaded sleeve 22. The corresponding threaded sleeves 22 on both sides of the shell 1 are electrically connected to each other.

[0026] In this arrangement, the threaded sleeve 22 is made of a conductive material, the connecting portion 211 is threadedly connected to the threaded sleeve 22, the threaded sleeve 22 maintains an electrical connection with the puncture screw 21, and at the same time, the threaded sleeves 22 corresponding to the two sides of the shell 1 are electrically connected. When the connecting portion 211 is screwed, the threaded sleeve 22 pushes the connecting portion 211 to move through the thread and drives the puncture portion 212 to approach and puncture the wire, thereby realizing the electrical connection of the corresponding wires on both sides of the shell 1.

[0027] Optionally, see Figure 3 and Figure 4 A puncture thread is provided on the outer peripheral surface of the puncture portion 212.

[0028] With such a configuration, when the puncture screw 21 is turned to cause the puncture portion 212 to puncture the wire, the spiral teeth on the puncture thread can penetrate into the wire core, thereby increasing the contact area between the puncture screw 21 and the wire core, improving the electrical connection effect between the two, and making the fixed connection between the two more stable.

[0029] In some embodiments, see Figures 1 to 5 A sealing end cover 3 is slidably provided on the shell 1 , a slide groove 13 is opened on the shell 1 , a guide bar 31 is fixedly provided on the sealing end cover 3 , and the guide bar 31 is slidably connected to the inside of the slide groove 13 .

[0030] With such a configuration, when wiring, the sealing end cover 3 can be pushed to slide on the shell 1 toward one side of the shell 1 to open the wiring device, and then the puncture screw 21 can be operated. After the wiring is completed, the sealing end cover 3 is pushed back to its original position to seal the opening of the shell 1. The sealing end cover 3 can prevent dust, rainwater, etc. outside the connecting device from entering the inside of the connecting device, and can protect the electronic components inside the connecting device.

[0031] Optionally, in some embodiments, see Figure 1 The shell 1 and the sealing end cover 3 are both fixedly provided with a connecting ring 32 , and the shell 1 and the sealing end cover 3 are connected by corresponding connecting rings 32 bolts.

[0032] With such arrangement, the connecting ring 32 can make the connection between the sealing end cover 3 and the housing 1 more stable, thereby improving the protection effect of the sealing end cover 3 on the electronic components inside the connecting device.

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
