Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment manufacturing technology, and in particular to an auxiliary installation structure for electricity meters and data acquisition terminals. Background Technology

[0002] Single-phase energy meters typically have two sampling devices (relays and current transformers). Both devices are connected to the circuit board using pin connectors, while the voltage terminals connected to the sampling devices are usually fixed to the meter housing using screws. Due to the low machining precision of the screw holes for the copper pins of the voltage terminals, it is difficult to align the pins of the sampling device with the sockets on the circuit board after fixing the voltage terminals to the housing. When pin misalignment is found after installing the sampling device, there are two adjustment methods:

[0003] First, observe the direction of pin offset, loosen the screws on the copper pins to adjust the position of the sampling device, and ensure that the pins are aligned with the socket. This method will not have any effect on the pins, but it takes a lot of time and sometimes even requires repeated adjustments.

[0004] Secondly, observe the pin offset direction and directly adjust the pin with pliers to align it with the pinhole on the PCB board. This method is suitable for pins with small offsets. Although the adjusted pin can be inserted into the socket, the height of the pin protruding from the socket will be reduced, increasing the risk of detachment after soldering. Furthermore, repeated adjustments increase the likelihood of pin breakage. If a pin breaks, it must be returned to the manufacturer for replacement, significantly impacting the assembly efficiency of the electricity meter. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary installation structure for electricity meters and data acquisition terminals. This auxiliary installation structure can realize the positioning and installation of the sampling device relative to the electricity meter housing, ensuring that the pins of the sampling device are aligned with the sockets of the circuit board. It ensures that the pins of the sampling device can be accurately inserted into the sockets of the circuit board when it is installed on the circuit board, which can save the assembly time of the circuit board, improve efficiency, avoid damage to the pins of the sampling device, and improve the assembly yield.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model discloses an auxiliary installation structure for an electricity meter and a data acquisition terminal, comprising: a mounting plate having two opposing first sidewalls and a second sidewall adjacent to the two first sidewalls, the two first sidewalls being able to abut against the inner sidewall of the housing of the electricity meter or the data acquisition terminal, the second sidewall having a positioning structure, the positioning structure being positioned and connected to the housing; and a support block connected to the mounting plate and abutting against the bottom wall of the housing; wherein: the mounting plate is provided with a plurality of pin holes, the pin holes being used to cooperate with the pins of the sampling device of the electricity meter or the data acquisition terminal, and the plurality of pin holes being configured one-to-one with a plurality of sockets on the circuit board of the electricity meter or the data acquisition terminal.

[0008] In some embodiments, the positioning structure includes a positioning part, one of the positioning part and the housing is provided with a positioning post, and the other of the positioning part and the housing is provided with a positioning hole that cooperates with the positioning post.

[0009] In some specific embodiments, the positioning post is a wedge-shaped post.

[0010] In some embodiments, the pin hole has a tapered section with a gradually decreasing diameter and a straight section with a constant diameter, the straight section being connected to the small end of the tapered section.

[0011] In some embodiments, the support blocks are arranged in pairs, and the two support blocks arranged in pairs correspond to the two second sidewalls.

[0012] In some embodiments, the support block and the mounting plate are integrally formed.

[0013] In some embodiments, the support block is detachably connected to the mounting plate.

[0014] In some specific embodiments, the mounting plate is provided with a first mounting hole, and the support block is provided with a second mounting hole corresponding to the first mounting hole. The mounting component passes through the first mounting hole and connects with the second mounting hole to mount the support block onto the mounting plate.

[0015] In some embodiments, the mounting plate is provided with a through hole for an operator to pass through in order to hold the sampling device on the mounting plate.

[0016] In some specific embodiments, the sampling device includes a current transformer and a relay. The pin hole is divided into a plurality of first pin holes and a plurality of second pin holes. The plurality of first pin holes are configured to correspond to the pins of the current transformer, and the plurality of second pin holes are configured to correspond to the pins of the relay. The through hole includes a first hole and a second hole. The first hole is configured to correspond to the plurality of first pin holes, and the second hole is configured to correspond to the plurality of second pin holes.

[0017] The auxiliary installation structure for electricity meters and data acquisition terminals of this utility model has the following advantages: In the actual assembly process, the pins of the sampling device are first inserted into the pin holes, and then the sampling device is held on the mounting plate. The mounting plate is then placed into the outer casing, so that the support block abuts against the bottom wall of the outer casing. At the same time, it is ensured that the two first side walls of the mounting plate abut against the inner wall of the outer casing of the electricity meter or data acquisition terminal, and that the positioning structure on the second side wall is positioned and connected to the outer casing. At this time, the copper feet of the sampling device are fixed in the outer casing with screws. Then, the mounting plate is removed from the outer casing. Since the multiple pin holes correspond one-to-one with the multiple sockets on the circuit board of the electricity meter, when the circuit board is installed into the outer casing, the pins of the sampling device can be accurately inserted into the sockets of the circuit board. This can save the assembly time of the circuit board, improve efficiency, avoid damage to the pins of the sampling device, improve the assembly yield, and ensure that the pins extend a longer length from the circuit board, ensuring the stability after soldering.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] This utility model discloses an auxiliary installation structure for electricity meters and data acquisition terminals (hereinafter referred to as the auxiliary installation structure for ease of description), see reference. Figure 1 and Figure 2As shown, the auxiliary installation structure includes a mounting plate 100 and a support block 200. The mounting plate 100 has two opposing first sidewalls 110 and a second sidewall 120 adjacent to the two first sidewalls 110. The two first sidewalls 110 can abut against the inner sidewall of the housing of the energy meter or data acquisition terminal. The second sidewall 120 has a positioning structure that is positioned and connected to the housing. The support block 200 is connected to the mounting plate 100 and abuts against the bottom wall of the housing. The mounting plate 100 is provided with a plurality of pin holes 140, which are used to cooperate with the pins of the sampling device of the energy meter or data acquisition terminal. The plurality of pin holes 140 are configured to correspond one-to-one with the plurality of sockets on the circuit board of the energy meter or data acquisition terminal. Understandably, in the actual assembly process, the pins of the sampling device are first inserted into the pin holes 140. Then, the sampling device is held on the mounting plate 100, and the mounting plate 100 is placed into the housing, so that the support block 200 abuts against the bottom wall of the housing. Simultaneously, it is ensured that the two first sidewalls 110 of the mounting plate 100 abut against the inner wall of the housing, and that the positioning structure on the second sidewall 120 is positioned and connected to the housing. At this point, screws are used to fix the copper pins of the sampling device inside the housing. Then, the mounting plate 100 is removed from the housing. Since the multiple pin holes 140 correspond one-to-one with the multiple sockets on the circuit board of the energy meter, when the circuit board is then installed into the housing, the pins of the sampling device can be accurately inserted into the sockets on the circuit board. This saves assembly time, improves efficiency, avoids damage to the pins of the sampling device, improves assembly yield, and ensures a longer pin extension length from the circuit board, ensuring stability after soldering. The data acquisition terminal can be an ammeter, voltmeter, or other test meter for acquiring circuit signals.

[0030] refer to Figure 1 As shown, the positioning structure includes a positioning part 130, which has a positioning hole 131, and a positioning post on the outer shell that mates with the positioning hole 131. It can be understood that during actual assembly, the positioning post is inserted into the positioning hole 131 to achieve the positioning and installation of the mounting plate 100 relative to the outer shell. This facilitates fixing the mounting plate 100 inside the outer shell and ensures the positioning accuracy of the mounting plate 100 inside the outer shell, thereby ensuring that the pins of the sampling device can be accurately inserted into the sockets of the circuit board.

[0031] Optionally, the positioning post is a wedge-shaped post. Thus, during the installation of the mounting plate 100, the wedge-shaped positioning post can be smoothly inserted into the positioning hole 131, thereby conveniently fixing the mounting plate 100 into the inside of the housing.

[0032] Of course, in alternative embodiments of this utility model, the positioning part 130 is provided with a positioning post, and the outer shell is provided with a positioning hole 131 that cooperates with the positioning post. It should be further noted that in other embodiments of this utility model, the positioning structure can also be a combination structure of a snap-fit ​​structure, a positioning groove and a positioning protrusion, or other structures that can achieve positioning connection, and is not limited to the combination structure of the positioning hole 131 and the positioning post described above.

[0033] Optionally, the pinhole 140 has a tapered section with a gradually decreasing diameter and a straight section with a constant diameter, the straight section being connected to the smaller end of the tapered section. It is understood that when the pins of the sampling device are inserted into the pinhole 140, the tapered section facilitates pin insertion while preventing pin misalignment, ensuring that the pins of the sampling device are accurately positioned under the action of the mounting plate 100, thereby enabling accurate insertion into the socket of the circuit board.

[0034] Optionally, the support blocks 200 are arranged in pairs, with the two pairs of support blocks 200 corresponding to the two second sidewalls 120. It is understood that the paired support blocks 200 ensure the stability of the mounting plate 100 within the housing, preventing assembly deviations caused by misalignment of the mounting plate 100. Of course, in other embodiments of this invention, the number and arrangement of the support blocks 200 can be adjusted according to actual needs and are not limited to a paired arrangement.

[0035] Optionally, the support block 200 and the mounting plate 100 are integrally molded. It is understood that having the support block 200 and the mounting plate 100 as an integrally molded part simplifies the structure of the auxiliary installation structure and reduces its manufacturing cost.

[0036] Optionally, the support block 200 and the mounting plate 100 are detachably connected. It is understood that during actual assembly, the depth of the outer casing may vary depending on the model of the electricity meter. Designing the support block 200 and the mounting plate 100 as detachable structures allows for the selection of a suitable height for the support block 200 based on the depth of the outer casing during actual assembly. This makes the auxiliary installation structure of this embodiment applicable to various models of electricity meters or data acquisition terminals.

[0037] Further optional, such as Figure 3As shown, the mounting plate 100 has a first mounting hole 150, and the support block 200 has a second mounting hole 210 corresponding to the first mounting hole 150. The mounting component 300 passes through the first mounting hole 150 and connects to the second mounting hole 210 to mount the support block 200 onto the mounting plate 100. It can be understood that in the actual assembly process, it is only necessary to attach the support block 200 to the mounting plate 100, aligning the second mounting hole 210 with the first mounting hole 150, and then connect the mounting component 300 through the first mounting hole 150 and the second mounting hole 210 to mount the support block 200 onto the mounting plate 100. This connection method is convenient to operate and has high reliability. In this embodiment, the mounting component 300 is a screw, the first mounting hole 150 is a smooth hole, and the second mounting hole 210 is a threaded hole. Of course, in other embodiments of this utility model, the mounting component 300 can also be a pin or other structural component.

[0038] Optionally, the mounting plate 100 is provided with a through hole 160, which allows an operator to pass through and hold the sampling device on the mounting plate 100. As described above, in the actual assembly process, the pins of the sampling device are first inserted into the pin holes 140, and then the sampling device is held on the mounting plate 100. By providing the through hole 160, the operator can insert the pins of the sampling device into the pin holes 140, and then press the side wall of the sampling device through the through hole 160 to hold it on the mounting plate 100, thus facilitating the positioning and installation of the sampling device.

[0039] Optionally, the sampling device includes a current transformer and a relay. The pin hole 140 is divided into multiple first pin holes 141 and multiple second pin holes 142. The multiple first pin holes 141 are configured to correspond to the pins of the current transformer, and the multiple second pin holes 142 are configured to correspond to the pins of the relay. The through hole 160 includes a first hole 161 and a second hole 162. The first hole 161 is configured to correspond to the multiple first pin holes 141, and the second hole 162 is configured to correspond to the multiple second pin holes 142. Understandably, during the actual assembly process, the operator first inserts the current transformer pins into the first socket 141 on the mounting plate 100, and uses the first hole 161 to hold the mounting plate 100 on the mounting plate. Then, the operator places the mounting plate 100 into the housing, aligning the positioning hole 131 with the positioning post. Next, screws are used to fix the copper feet of the current transformer inside the housing to complete the connection with the voltage terminals. Then, the operator picks up the mounting plate 100, inserts the relay pins into the second socket 142 on the mounting plate 100, and uses the second hole 162 to hold the mounting plate 100 on the mounting plate. Then, the operator places the mounting plate 100 into the housing, aligning the positioning hole 131 with the positioning post. Finally, screws are used to fix the copper feet of the relay inside the housing to complete the connection with the voltage terminals. It should be noted that the reason why the current transformer and relay are not installed at the same time during the actual assembly process is that the mounting plate 100 is on top and the current transformer and relay are on the bottom. The operator cannot hold the three components firmly at once. During the step of placing the outer casing, the current transformer and relay are easy to fall off the mounting plate 100.

[0040] In the description of this specification, references to terms such as "some embodiments," "other embodiments," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
