Description

Technical Field

[0001] This utility model relates to the field of electricity meter accessories technology, and in particular to a rubber plug structure for electricity meters. Background Technology

[0002] Electricity meters have electrical sockets that can be used to transmit data and electrical energy. Because electricity meters need to be waterproof and dustproof, the electrical sockets need to be sealed with rubber plugs when not in use. To prevent the rubber plugs from being lost, the rubber plug generally consists of a connected body and a locking pin. The rubber plug is secured to the meter body by the locking pin. When opening the electrical socket, simply pry open the body of the rubber plug. The engagement between the locking pin and the locking hole on the meter body ensures that the rubber plug will not separate from the meter. After the electrical socket is no longer in use, simply reseal the electrical socket using the body.

[0003] During the production and assembly of electricity meters, employees typically first pass the guide part of the locking pin of the rubber stopper through the corresponding locking hole in the main body of the meter. Then, they use a tool to clamp the guide part of the locking pin and forcefully push the locking head of the locking pin through the locking hole so that the locking hole can lock the locking pin. Because the guide part of the locking pin is usually quite long and takes up space in the meter, after the locking head passes through the locking hole, automated equipment or manual labor is needed to cut off the guide part of the locking pin. The existence of the process of cutting off the guide part of the rubber stopper undoubtedly increases costs. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a rubber stopper structure for electricity meters that can reduce assembly costs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a rubber stopper structure for electricity meters, comprising:

[0006] The body has a mating plug and a bending groove on its inner side;

[0007] A locking post is connected to the body and located on the side of the bending groove away from the mating plug. The locking post has a locking head and a guide portion. A locking groove is formed between the locking head and the body. The guide portion is connected to the locking head. A breakable groove is formed at the connection between the guide portion and the locking head.

[0008] In one embodiment, the mating plug is generally in the shape of a ring frame or a boss.

[0009] In one embodiment, the cross-sectional area of ​​the locking post corresponding to the breakable groove is 60%-90% of the cross-sectional area of ​​the guide portion.

[0010] In one embodiment, the connection point between the locking post and the body is located near one end of the body.

[0011] In one embodiment, the other end of the body is provided with a handle.

[0012] In one embodiment, the number of the locking posts is multiple.

[0013] In one embodiment, a plurality of the card slot posts are arranged in a row.

[0014] In one embodiment, the bending groove connects opposite sides of the body.

[0015] In one embodiment, the locking head includes a frustum portion and a cylindrical portion connected together. The small end of the frustum portion is connected to the guide portion through the breakable groove. The end face of the cylinder away from the frustum portion forms the locking groove between the cylinder and the body. The outer peripheral wall of the cylindrical portion is provided with a plurality of protrusions.

[0016] In one embodiment, there are multiple protrusions, and the multiple protrusions are evenly distributed around the central axis of the cylindrical portion.

[0017] The beneficial effects of this utility model are as follows: The rubber plug structure of this electricity meter is simple and novel, and easy to process and manufacture. During the assembly of the electricity meter, the guide part of the locking post of the rubber plug structure is first passed through the corresponding locking hole of the electricity meter body. Then, a tool is used to clamp the guide part of the locking post, and the locking head of the locking post is squeezed through the locking hole so that the locking hole can lock the locking post. Continuing to pull the guide part will cause the easy-break groove of the locking post to break, so that the guide part is detached from the locking post, thereby omitting the subsequent process of cutting the guide part, which helps to improve the assembly efficiency of the electricity meter and reduce the assembly cost.

[0030] Example 1

[0031] Please refer to Figure 1 and Figure 2 One embodiment of this utility model is as follows: a rubber plug structure for an electricity meter, including a body 1 and a locking post 2. The inner side of the body 1 has a mating plug 11 and a bending groove 12. The bending groove 12 connects the opposite sides of the body 1. The mating plug 11 can effectively block the electrical socket on the electricity meter. The locking post 2 is connected to the body 1 and is located on the side of the bending groove 12 away from the mating plug 11. The locking post 2 has a locking head 21 and a guide part 22. The locking head 21 and the body 1 form a locking groove 23. The locking groove 23 engages with the edge of the locking hole on the electricity meter body to form a locking connection. The guide part 22 is connected to the locking head 21. The connection between the guide part 22 and the locking head 21 forms a breakable groove 24. The presence of the bending groove 12 allows the area of ​​the body 1 corresponding to the mating plug 11 to rotate relative to the area of ​​the body 1 connected to the locking post 2, thereby realizing the opening and closing of the mating plug 11 for the electrical socket on the electricity meter.

[0032] Preferably, the body 1 and the locking post 2 are integrally injection molded structural components.

[0033] In this embodiment, the mating plug 11 is generally in the shape of a ring frame. In other embodiments, the mating plug 11 may also be generally in the shape of a boss.

[0034] The cross-sectional area of ​​the positioning post 2 corresponding to the breakable groove 24 is 60%-90% of the cross-sectional area of ​​the guide part 22. The cross-sectional area of ​​the positioning post 2 corresponding to the breakable groove 24 needs to be determined comprehensively by combining the physical properties of the material of the positioning post 2 and the cross-sectional area of ​​the guide part 22. This can be determined by those skilled in the art through a number of effective experiments without any creative effort.

[0035] The connection point between the locking post 2 and the body 1 is located near one end of the body 1. To facilitate the user opening the mating plug 11, the other end of the body 1 is provided with a handle position 13.

[0036] The number of the positioning posts 2 is one or more, preferably multiple, and the multiple positioning posts 2 are arranged in a row.

[0037] Specifically, the clip 21 includes a connected frustum 211 and a cylindrical portion 212. The small end of the frustum 211 is connected to the guide portion 22 through the breakable groove 24. The end face of the cylinder away from the frustum 211 forms the locking groove 23 between it and the body 1. The outer peripheral wall of the cylindrical portion 212 is provided with a plurality of protrusions 213. The presence of the protrusions 213 allows the clip 21 to better cooperate with the locking hole on the meter, reducing the risk of the rubber plug structure of the meter detaching from the meter body.

[0038] In a preferred embodiment, there are multiple protrusions 213, which are evenly distributed around the central axis of the cylindrical portion 212. In this embodiment, there are four protrusions 213.

[0039] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the utility model concept, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
