Description

Technical Field

[0001] This utility model belongs to the field of electricity meter technology and relates to a wireless beam terminal device for external wiring of electricity meters. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy. When wiring a traditional electricity meter, the relay needs to be soldered or crimped to the terminal via wires, which can easily lead to the risk of loose wires or poor soldering. Therefore, in order to improve the reliability and safety of the connection, the terminal contact is achieved by direct plug-in or snap-fit ​​contact to avoid control failure due to poor wire contact.

[0003] A connection device for an electricity meter relay disclosed in Chinese patent CN222966018U includes a relay and a conductive rod connected to the relay. A copper sheet extends from the side of the relay. The connection device is disposed between the copper sheet and the conductive rod. The connection device includes a positioning post disposed on one of the copper sheet or the conductive rod and a positioning hole into which the positioning post can be inserted. The positioning post is fixedly disposed in the positioning hole.

[0004] During connection, the second bent piece is fixed to the end of the conductive rod. This results in only the end surface of the conductive rod contacting the second bent piece, leading to a small contact area. Furthermore, installation requires inserting a positioning pin into the positioning hole and soldering, making disassembly inconvenient.

[0005] To solve the above problems, this utility model proposes a wireless wiring terminal device for external wiring of an electricity meter. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a wireless wiring terminal device for external wiring of an electricity meter.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a housing of an electricity meter, a relay is fixedly installed inside the housing, a window is opened at one end of the housing, and a number of wiring shells are fixedly installed at intervals inside the window, and a conductive block is fixedly connected to one end of each wiring shell;

[0008] The relay's power-connecting terminal is provided with a second connecting piece and a third connecting piece. Both the second and third connecting pieces are movably snapped onto the outside of the conductive block. A U-shaped first connecting piece is movably snapped onto the outside of the conductive block and the second connecting piece. The surfaces of the first connecting piece, the second connecting piece, the third connecting piece, and the conductive block are all wavy.

[0009] Furthermore, a connecting column is fixedly connected inside the window, and a cover is provided inside the window. The cover has a mounting hole that matches the connecting column, and a bolt is provided inside the mounting hole. The end of the bolt is threaded into the inside of the connecting column.

[0010] Furthermore, a number of wiring holes are spaced apart on the end face of the housing. The number of wiring holes is equal to the number of wiring shells and corresponds one-to-one. The wiring holes are connected to the inner cavity of the corresponding wiring shell.

[0011] Furthermore, each of the aforementioned wiring housings has two screws threaded through its top surface.

[0012] Furthermore, a conductive piece is inserted into the power terminal of the relay, and the second connecting piece and the third connecting piece are both fixedly connected to the end of the conductive piece away from the relay.

[0013] Furthermore, the wavy shapes on the top surface of the first connecting piece, the top and bottom surfaces of the conductive block, the top and bottom surfaces of the second connecting piece, and the top surface of the third connecting piece are all horizontally distributed, while the wavy shapes on the two sides of the first connecting piece, the outer top surface, the two sides of the conductive block, and the bottom surface of the third connecting piece are all vertically distributed. The first connecting piece, the second connecting piece, and the third connecting piece are all made of elastic metal material.

[0014] Furthermore, a slot is provided on the top surface of the conductive sheet away from the relay, and a locking block is fixedly connected to one side of the top of the first connecting sheet, with the locking block being movably positioned inside the slot.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The wireless terminal device for external wiring of the electricity meter is provided with a first connecting piece, a second connecting piece, and a third connecting piece. In use, by moving the conductive piece, the second connecting piece is pressed tightly against the top surface of the conductive block, and the third connecting piece is pressed tightly against the bottom surface of the conductive block. Then, the first connecting piece is moved so that it is pressed tightly against the outside of the conductive block, thereby contacting the entire outer surface of the conductive block. This increases the contact area with the conductive block while making the connection, reducing local heat generation.

[0017] 2. The first connecting piece, the second connecting piece, and the third connecting piece in the wireless terminal device for the external wiring of the electricity meter are all elastic and have a wavy outer surface, which makes them compatible with the shape of the conductive block surface, thereby making the connection tighter. The connection is achieved by simply snapping together, realizing wireless connection and facilitating disassembly. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: A wireless terminal device for external wiring of an electricity meter includes a housing 1 of the electricity meter, and a relay 6 is fixedly installed inside the housing 1. A window 13 is opened at one end of the housing 1, and a plurality of wiring shells 3 are fixedly installed at intervals inside the window 13. A conductive block 8 is fixedly connected to one end of each wiring shell 3. The wiring shell 3 is used to connect wires, and the conductive block 8 is used to conduct electricity.

[0026] The relay 6 has a second connecting piece 9 and a third connecting piece 10 at its energizing terminals. Both the second connecting piece 9 and the third connecting piece 10 are movably snapped onto the outside of the conductive block 8. The conductive block 8 is connected via the second connecting piece 9 and the third connecting piece 10 to facilitate external wiring of the relay 6.

[0027] A conductive piece 5 is inserted into the energized terminal of relay 6. The second connecting piece 9 and the third connecting piece 10 are both fixedly connected to the end of the conductive piece 5 furthest from the relay 6. The relay 6 is connected through the conductive piece 5.

[0028] The conductive block 8 and the second connecting piece 9 are externally engaged with a U-shaped first connecting piece 7, which positions the second connecting piece 9 onto the conductive block 8, making the connection more stable. The surfaces of the first connecting piece 7, the second connecting piece 9, the third connecting piece 10, and the conductive block 8 are all wavy.

[0029] The wavy shapes on the top surface of the first connecting piece 7, the top and bottom surfaces of the conductive block 8, the top and bottom surfaces of the second connecting piece 9, and the top surface of the third connecting piece 10 are all horizontally distributed. The wavy shapes on the two sides and the outer top surface of the first connecting piece 7, the two sides of the conductive block 8, and the bottom surface of the third connecting piece 10 are all vertically distributed. This ensures that the shapes of the first connecting piece 7, the second connecting piece 9, and the third connecting piece 10 match the shape of the outer surface of the conductive block 8, thereby making the connection tighter.

[0030] The first connecting piece 7, the second connecting piece 9, and the third connecting piece 10 are all made of elastic metal material. The elasticity allows the second connecting piece 9 and the third connecting piece 10 to snap onto the conductive block 8, while the first connecting piece 7 snaps onto the conductive block 8 and simultaneously fixes the second connecting piece 9, making the connection more stable.

[0031] A slot 11 is formed on the top surface of the conductive piece 5 at the end away from the relay 6. A locking block 12 is fixedly connected to one side of the top of the first connecting piece 7, and the locking block 12 is movably positioned inside the slot 11. The first connecting piece 7 is positioned by the cooperation of the slot 11 and the locking block 12, further increasing stability.

[0032] A connecting post 14 is fixedly connected inside the window 13, and a watch cover 2 is installed inside the window 13. The watch cover 2 has a mounting hole that matches the connecting post 14, and a bolt is installed inside the mounting hole. The end of the bolt is threaded into the connecting post 14. By rotating the bolt through the mounting hole into the connecting post 14, the watch cover 2 is fixed to the connecting post 14, thereby fixing the watch cover 2 to the window 13 and sealing the window 13.

[0033] Several wiring holes are spaced apart on the end face of housing 1. The number of wiring holes is equal to the number of wiring shells 3 and corresponds one-to-one. The wiring holes are connected to the inner cavity of the corresponding wiring shell 3. The wiring holes facilitate the insertion of the wire terminals into the wiring shell 3 for wiring.

[0034] Two screws 4 are threaded through the top surface of each terminal housing 3. The wires inserted into the terminal housing 3 are secured by the screws 4.

[0035] Working principle:

[0036] In use, move one end of the conductive sheet 5 to move the second connecting sheet 9 and the third connecting sheet 10 to one end of the conductive block 8.

[0037] Push the conductive piece 5 towards the side closest to the conductive block 8, lift the second connecting piece 9 upward, and rotate the third connecting piece 10 downward. This moves the second connecting piece 9 above the conductive block 8 and the third connecting piece 10 below the conductive block 8.

[0038] Until the conductive piece 5 contacts the end of the conductive block 8, release the second connecting piece 9 and the third connecting piece 10. Under the elasticity of their own bodies, the second connecting piece 9 and the third connecting piece 10 will return to their original shape, causing the second connecting piece 9 to abut against the top of the conductive block 8 and the third connecting piece 10 to abut against the bottom of the conductive block 8. Furthermore, through a wavy fit, the second connecting piece 9 and the third connecting piece 10 are secured to the conductive block 8.

[0039] Pick up the first connecting piece 7 and move its two sides away from each other. Move the two sides of the first connecting piece 7 outward from the conductive block 8, and move the top of the first connecting piece 7 towards the top of the second connecting piece 9.

[0040] Move the locking block 12 into the locking slot 11, positioning the first connecting piece 7 on top of the second connecting piece 9. Release the two sides of the first connecting piece 7; it will return to its original shape due to its own elasticity, causing the two sides of the first connecting piece 7 to abut against the conductive block 8. Furthermore, through a wavy fit, the first connecting piece 7 is secured to the conductive block 8.

[0041] The conductive sheet 5 and the conductive block 8 are connected by the second connecting piece 9, the third connecting piece 10, and the first connecting piece 7 to achieve a wireless connection and a direct mechanical connection between the terminals, making the connection more reliable and secure. Furthermore, the wavy design increases the contact surface with air, facilitating heat dissipation.

[0042] Then, pass one end of the wire through the wiring hole at the end of the housing 1 and into the corresponding wiring housing 3, and turn the screw 4 into the wiring housing 3 to fix the wire.

[0043] Move the watch cover 2 to the window 13 so that the mounting hole on the watch cover 2 aligns with the connecting post 14. Use bolts to fix the watch cover 2 to the window 13 and seal the window 13.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
