[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.
[0031] The following will describe embodiments of the present utility model in conjunction with Figures 1 to 7 .
[0032] According to an embodiment of the present utility model, on the one hand, as Figure 1 shown, a connection node structure between an electricity meter housing and a tail cover is provided, including: a housing 1 and a tail cover 2. A limiting bump 101 protrudes from the housing 1, and a wiring chamber is formed inside the housing 1. The tail cover 2 is rotatably connected to the housing 1, and a limiting clamping point 201 protrudes from the tail cover 2. The limiting bump 101 and the limiting clamping point 201 are both arranged corresponding to the rotation connection part of the housing 1 and the tail cover 2. The tail cover 2 has a closed position and an open position. In the closed position, the limiting clamping point 201 is located on one side of the limiting bump 101, and the tail cover 2 covers the wiring chamber. In the open position, the limiting clamping point 201 crosses over the limiting bump 101, and the limiting clamping point 201 is located on the other side of the limiting bump 101 and abuts against the limiting bump 101 to expose the wiring chamber.
[0033] Through the cooperation of the limiting bump 101 provided on the housing 1 and the limiting clamping point 201 provided on the tail cover 2, only by rotating the tail cover 2 so that the limiting clamping point 201 on the tail cover 2 crosses over the limiting bump 101 on the housing 1 and abuts and fixes against the limiting bump 101. At this time, operations inside the wiring chamber are not affected, and there is no need to disassemble the tail cover 2, avoiding the situation that the tail cover 2 is easily lost after disassembly.
[0034] In one embodiment, the housing 1 has a first rotation connection part 102 corresponding to the rotation connection part, and the tail cover 2 has a second rotation connection part 202 corresponding to the rotation connection part. The limiting bump 101 is arranged on the first rotation connection part 102, and the limiting clamping point 201 is arranged on the second rotation connection part 202.
[0035] In one embodiment, there are two first rotation connection parts 102, and the two first rotation connection parts 102 are arranged at intervals on opposite sides of the opening of the wiring chamber. The second rotation connection part 202 is inserted between the two first rotation connection parts 102.
[0036] In one embodiment, receiving grooves 204 are formed at both ends of the second rotation connection part 202, and the limiting clamping point 201 protrudes from the bottom of the receiving groove 204. The first rotation connection part 102 is inserted into the receiving groove 204 so that the limiting bump 101 is arranged corresponding to the limiting clamping point 201.
[0037] It should be noted that the first rotation connection part 102 can also be arranged as several, and the several first rotation connection parts 102 are arranged at intervals along the extending direction of the opening of the wiring chamber. The second rotation connection part 202 is provided with several receiving grooves 204, and the several first rotation connection parts 102 are correspondingly inserted into the several receiving grooves 204.
[0038] In one embodiment, the limiting bump 101 and / or the limiting clamping point 201 are elastic members. The elastic members are beneficial to reducing friction, avoiding damage caused by hard friction between the limiting clamping point 201 and the limiting bump 101, and improving the service life of the housing 1 and the end cover 2.
[0039] Specifically, in this embodiment, both the limiting bump 101 and the limiting clamping point 201 are made of polycarbonate material, which has good heat resistance, cold resistance, impact resistance and mechanical properties.
[0040] It should be noted that the limiting bump 101 and the limiting clamping point 201 can be any structural components with a certain elasticity, as long as it is satisfied that the limiting clamping point 201 can cross the limiting bump 101 without causing damage.
[0041] It should be further noted that from the perspective of the service cycle of the electricity meter, the operation of the limiting clamping point 201 crossing the limiting bump 101 (that is, opening the end cover 2 for wiring and closing the end cover 2 after wiring is completed) will not exceed 15 times. Therefore, the limiting bump 101 and the limiting clamping point 201 will not be damaged due to frequent friction.
[0042] In one embodiment, as Figure 3 and Figure 5 shown, the limiting bump 101 has a first arc surface 1011, and the limiting clamping point 201 has a second arc surface 2011. In the open position, the first arc surface 1011 is elastically abutted against the second arc surface 2011. Compared with a flat surface or a sharp corner, the arc surface has a smoother contact surface, so that the limiting clamping point 201 can more easily cross the limiting bump 101, reducing the friction between the limiting clamping point 201 and the limiting bump 101.
[0043] Specifically, in this embodiment, when the end cover 2 is in the open position, the first arc surface 1011 is elastically abutted against the second arc surface 2011, restricting the fall of the end cover 2 and keeping the end cover 2 in the open state, thus facilitating the operation in the wiring chamber.
[0044] In one embodiment, as Figures 1 to 7 shown, a rotating shaft 4 is arranged in the receiving groove 204, and a rotating shaft hole 5 is formed on the first rotating connection portion 102. The rotating shaft 4 is inserted into the rotating shaft hole 5. The cooperation of the rotating shaft 4 and the rotating shaft hole 5 is used to realize the rotational connection between the end cover 2 and the housing 1. The overall structure is simple and the cost is low, which is beneficial to the replacement and maintenance of the end cover 2.
[0045] In an alternative embodiment, the rotating shaft hole 5 can be formed in the receiving groove 204, and the rotating shaft 4 is arranged on the first rotating connection portion 102, which can also realize the rotational connection between the housing 1 and the end cover 2.
[0046] Specifically, in this embodiment, as Figure 2 shown, there are two rotating shafts 4, and the two rotating shafts 4 are respectively arranged in the two receiving grooves 204 of the second rotating connection part 202 and are respectively rotatably connected to the two rotating shaft holes 5 formed on the first rotating connection part 102.
[0047] In an alternative embodiment, the rotating shaft 4 can be set to one, and one rotating shaft 4 penetrates through the second rotating connection part 202 and is rotatably connected to the rotating shaft holes 5 formed on the two first rotating connection parts 102.
[0048] In one embodiment, please refer to Figure 2 , when in the open position, the included angle α between the tail cover 2 and the housing 1 is 60° - 63°.
[0049] In one embodiment, as Figure 1 and Figure 2 shown, a first connection hole 203 is formed on the tail cover 2, a wiring component 3 is adapted to be installed in the housing 1, a second connection hole 301 is formed on the wiring component 3, and the connection node structure between the electric energy meter housing and the tail cover further includes a fastener 6, and the fastener 6 is inserted into the first connection hole 203 and the second connection hole 301 at the same time. By providing the fastener 6 to connect the tail cover 2 and the wiring component 3, the coverage of the wiring component 3 by the tail cover 2 is made more firm when the tail cover 2 is in the closed position, fully protecting the wiring component 3 and improving the use safety of the electric energy meter.
[0050] Specifically, in this embodiment, a protective shell is sleeved outside the fastener 6, and the protective shell has a grip portion corresponding to the end of the fastener 6. By providing the grip portion, it is convenient for the staff to tighten and loosen the fastener 6.
[0051] It should be noted that, in this embodiment, the tail cover 2 is a transparent tail cover 2. By providing the transparent tail cover 2, it can be observed whether the wiring of the wiring component 3 is disconnected, which is clear and intuitive, making the use of the electric energy meter more convenient.
[0052] According to an embodiment of the present invention, on the other hand, an electric energy meter is further provided, including the connection node structure between the electric energy meter housing and the tail cover as described above.
[0053] It is worth noting that using the connection node structure between the electric energy meter housing and the tail cover of this embodiment simplifies the mold design of the electric energy meter, reduces the mold cost, and is beneficial to improving the economic benefits.
[0054] When using the electric energy meter of this embodiment, when on-site construction requires wiring operation on the wiring component 3, first, open the fastener 6 and lift the tail cover 2 upward. The limit clamping point 201 crosses the limit convex point 101 and abuts and fixes with the limit convex point 101. At this time, perform wiring operation on the wiring component 3. Then, after wiring is completed, press down the tail cover 2 forcefully to push the limit clamping point 201 past the limit convex point 101 and connect the tail cover 2 and the wiring component 3 with the fastener 6 to cover and enclose the wiring component 3 that has completed wiring.
[0055] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
