Description

Technical Field

[0001] This utility model relates to the field of meter holder technology, specifically to a meter mounting socket. Background Technology

[0002] With the construction of the global power grid, electricity meters have gradually become common in households. The installation, maintenance, and replacement of electricity meters are problems that technicians often face. At the same time, as people's fire safety awareness continues to improve, the requirements for the safety performance of electricity meters are also increasing. Today, plug-in electricity meter technology has gradually matured, and matching meter sockets have emerged.

[0003] The common problem with existing meter holders is that although the plug-in installation of meter spring contacts is convenient, the spring contacts are easily affected by aging or repeated plugging and unplugging, which can lead to a decrease in clamping force and a decrease in the contact stability of the conductive connection, posing a potential hazard. In addition, the installation of existing meter holders is also very limited, and the common screw fixing not only requires the mating surface to be suitable, but is also very unfavorable for replacement and reinstallation after disassembly.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0018] like Figure 1-5The diagram shows an electrical meter mounting socket, including a housing 1. The housing 1 has an insulating base 2 inside, and a conductive sheet 3 is provided on the insulating base 2. One end of the conductive sheet 3 extends to form a spring clip 4, and the other end is a wire clamping part 5. The insulating base 2 has an arc groove 41 and a C-shaped fastener 42 at the position opposite to the spring clip 4. The two ends of the C-shaped fastener 42 abut against the two sides of the spring clip 4. The back of the housing 1 is also provided with a mounting part 9 for fixing relative to the electrical box cabinet.

[0019] As a further provision of the above scheme, the insulating base 2 is provided with a pad 22 on the mounting surface 21 of the spring clip 4. The pad 22 has four pads, the upper ends of which abut against the spring clip 4 and form a contact gap 23. The conductive sheet 3 is provided with a corrugated groove 44. The conductive sheet 3 is also provided with a pressure plate 43 on the upper side of the spring clip 4. The pressure plate 43, the conductive sheet 3 and the insulating base 2 are provided with two opposing fixing holes 45. The pressure plate 43 is installed relative to the insulating base 2 through the fixing holes 45. The gap of the fixing holes 45 is set to be greater than the width of the C-type fastener 42. The pressure plate 43 is located above the conductive sheet 3 and is fixed to the insulating base 2 by bolts passing through the fixing holes 45.

[0020] As a further feature of the above scheme, the inner cavity of the housing 1 is provided with a grounding terminal block 12, and the wall of the housing 1 is provided with a radial wire hole 11.

[0021] As a further feature of the above solution, the mounting component 9 includes a pad post 91 with a perforation 92 located on the back of the housing 1. The perforation 92 on the pad post 91 is arranged in both horizontal and vertical directions. The perforation 92 can be used for the passing and binding of the strip. The user can use any two of the pad posts 91 with the perforation 92 to achieve horizontal or vertical binding and fixing of the strip on the mounting frame by passing it through the strip according to the installation angle requirements.

[0022] Example 1: The meter mounting socket of this example includes a housing 1, and the inner cavity of the housing 1 is provided with an insulating seat 2, such as... Figure 1 As shown, the housing 1 of this embodiment is provided with two sets of insulating seats 2. The insulating seats 2 are fixed to corresponding positions at the bottom of the inner cavity of the housing 1 by screws. A grounding terminal seat 12 is provided in the middle of the two sets of insulating seats 2. (Refer to...) Figure 2 As shown, the back of the housing 1 is also provided with a mounting member 9 for fixing relative to the electrical cabinet. The mounting member 9 includes a pad post 91 with a through hole 92 located on the back of the housing 1, and the through hole 92 on the pad post 91 includes both horizontal and vertical arrangements.

[0023] refer to Figure 3 The insulating base 2 shown in this embodiment is further provided with a conductive sheet 3. One end of the conductive sheet 3 extends to form a spring clip 4, and the other end is a wire clamping part 5. (See reference) Figure 4In this embodiment, the insulating base 2 is provided with an arc groove 41 and a C-shaped fastener 42 at the position opposite to the spring clip 4. The two ends of the C-shaped fastener 42 abut against the two sides of the spring clip 4. The mounting surface 21 of the insulating base 2 opposite to the spring clip 4 is provided with a pad 22. The pad 22 has four pads, the upper ends of which abut against the spring clip 4 and form a contact gap 23. The function of this contact gap 23 is that when the conductive sheet 3 is in use, it carries current and generates a certain amount of heat. Forming the contact gap 23 can reduce the direct contact area between it and the insulating base 2. One is to facilitate heat dissipation and the other is to reduce the heat transfer to the insulating base 2. Generally, this kind of insulating base 2 is made of plastic material. Therefore, high temperature can easily cause it to age faster and reduce its service life. In addition, the setting of the contact gap 23 allows the wire pressing part 5 to have a certain swing range and a certain elastic deformation force when pressing the wire. In this way, under the reaction of the elastic deformation of the wire pressing part 5 in the locked state, it will have a locking and anti-loosening effect on the screw.

[0024] As a further feature of the above solution, the conductive sheet 3 is provided with a corrugated groove 44, and a pressure plate 43 is also provided on the upper side of the conductive sheet 3 at the spring clip 4. The pressure plate 43, the conductive sheet 3, and the insulating base 2 are provided with two opposing fixing holes 45. The pressure plate 43 is installed relative to the insulating base 2 through the fixing holes 45. Figure 3 and Figure 4 As shown, the installation of the conductive sheet 3 and the C-shaped fastener 42 in this embodiment is very simple. The C-shaped fastener 42 can be inserted radially into the spring clip 4 from the side, and then aligned with the arc groove 41 and inserted. Then, the pressure plate 43 is placed on the conductive sheet 3 between the two spring clips 4 from the front. Finally, it can be quickly installed by locking it with two screws from the fixing hole 45. The C-shaped structure of the C-shaped fastener 42 provides a very strong elastic recovery force for the spring clip 4, which enables it to maintain more insertion and removal retention force and meet the installation and use requirements.

[0025] As a further feature of the above scheme, the gap of the fixing hole 45 is set to be greater than the width of the C-type fastener 42. The pressure plate 43 is located above the conductive sheet 3 and passes through the fixing hole 45 with bolts to thread the conductive sheet 3 and the C-type fastener 42 onto the insulating base 2.

[0026] As a further provision of the above solution, the inner cavity of the housing 1 is provided with a grounding terminal seat 12, and the wall of the housing 1 is provided with a radial wire hole 11. Further referring to the prior art, the wire hole 11 can be provided with a threaded structure to maintain the seal at the wire hole 11. Thus, with the seamless arrangement of the inner cavity and the back of the housing 1 in this embodiment, after the sealing and mating structure of the meter with the front opening is installed, the inner cavity of the housing 1 can be kept relatively closed to the outside world for use scenarios where sealing is required.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
