Description

Technical Field

[0001] The utility model relates to an electric meter device, in particular to a remote meter reading concentrator for power grids with a replaceable communication module. Background Technique

[0002] The electric meter reading concentrator collects and synchronizes electric meter readings through automation technology, improving efficiency and accuracy, and has functions such as remote control and abnormal alarm. It is widely used in various sites to assist in energy management and power dispatching.

[0003] The main functions of the electric meter reading concentrator include remote control data collection, data processing, abnormal reporting, and remote operation. It mainly interacts with each intelligent electric meter through wireless transmission technologies (such as GPRS, LoRa, NB-IoT, etc.) to obtain electric meter readings in real time. Once abnormal power consumption is found, such as load, deduction, etc., the concentrator will immediately push warning information, which is conducive to proper handling.

[0004] Among them, the electric meter reading concentrator mainly relies on the communication module to realize data transceiver of multiple electric meters, complete large-scale meter reading, and improve work efficiency; the batch data transceiver under high-frequency and high-load conditions all year round results in the failures of the concentrator concentrating in the communication module. When the communication module fails (the most common is overloading and burning), the module needs to be replaced in time.

[0005] The joint structures of the communication module are of two types: contact type and pin type. The former has newer technology, and the latter has more mature technology. Both have their own advantages and disadvantages; the contact type structure better meets the requirements of interface miniaturization, but the pin type interface has excellent voltage and current carrying capacities. High-quality materials and advanced processes can reduce the contact resistance of the pin type interface, helping to reduce signal attenuation and energy loss, and improving the transmission efficiency of the system; in addition, the pin type interface has good vibration and shock resistance, which can ensure the stability and reliability of the device in a complex environment.

[0006] Considering the operating conditions of the communication module in the electric meter concentrator, the pin type joint structure is generally adopted. The disadvantages of the pin type joint structure are also obvious. During the plugging and unplugging process, it must be strictly aligned. If there is a deviation, it is very easy to cause the pins to bend, or even break. Content of the Utility Model

Detailed implementation mode

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0044] Please refer to Figures 1 to 17 , as an embodiment of the present invention, the remote power grid meter reading concentrator with replaceable communication module includes a meter concentrator body 1. One side of the meter concentrator body 1 is integrated with a communication connector 3, a liquid crystal display screen 4, an optical communication port 5, and a 4G module 6. And a carrier / wireless communication module 2 is arranged on the same side of the meter concentrator body 1. The carrier / wireless communication module 2 is detachably connected to the communication connector 3 through an alignment component;

[0045] One side of the carrier / wireless communication module 2 is integrally provided with a pin socket 201, and one side of the communication connector 3 is integrally provided with a pin plug 301 adapted to the pin socket 201; the alignment component is used to coaxially align the pin socket 201 and the pin plug 301;

[0046] Among them, a row of terminal blocks 7 is also integrally arranged on the meter concentrator body 1.

[0047] Through the provided alignment component, the pin socket 201 on the carrier / wireless communication module 2 can approach and insert into the pin plug 301 only after being completely coaxially aligned with the pin plug 301, avoiding problems such as the pin being pressed and deformed, bent or broken due to the pin socket 201 approaching each other before being completely aligned with the pin plug 301.

[0048] As a further solution of the present invention, the communication connector 3 is also integrated with a USB interface 302 and an RS232 interface 303.

[0049] Serial communication is achieved by using the set RS232 interface 303, which allows the concentrator to be connected to various peripheral devices to realize two-way data transmission. Similarly, the data output within the concentrator is also facilitated by using the set USB interface 302.

[0050] As a further solution of the present utility model, the alignment component includes a fixed seat 202 provided on the meter concentrator body 1, a mounting member 203 mounted on the fixed seat 202, and a plug 204 provided on the carrier / wireless communication module 2;

[0051] A slot 2031 adapted to the plug 204 is formed on the mounting member 203, and a stop structure is provided on the mounting member 203. The stop structure is used to restrict the plug 204 to move only along its length direction when the plug 204 is not fully inserted into the slot 2031.

[0052] Since the mounting member 203 is mounted on the meter concentrator body 1 through the fixed seat 202, the distance between the plug 204 and the meter concentrator body 1 can be restricted by the cooperation of the plug 204 and the slot 2031, that is Figure 1 the front and rear position constraints; and under the action of the stop structure, it can effectively prevent the pin socket 201 and the pin plug 301 from Figure 1 not being able to move up and down when the left and right orientations are not aligned in the perspective.

[0053] As a further solution of the present utility model, a guiding portion 2022 is provided on one side of the fixed seat 202, a stop member 205 is movably provided on the other side, and a calibration portion 2021 is integrally provided on the fixed seat 202;

[0054] The calibration portion 2021 is provided between the stop member 205 and the guiding portion 2022. The surface of the calibration portion 2021 away from the slot 2031 is an inclined surface, and the surface of the calibration portion 2021 close to the plug 204 is at the same height as the surface of the slot 2031 close to the fixed seat 202;

[0055] Both the guiding portion 2022 and the stop member 205 are bent. A guiding channel is formed between the guiding portion 2022 and the stop member 205. One end of the guiding channel away from the 4G module 6 is opened to form a guiding port, and the other end of the guiding channel forms a positioning port. The distance between the guiding portion 2022 and the stop member 205 at the positioning port is the same as the width of the plug 204.

[0056] The gap between the fixed seat 202 and the carrier / wireless communication module 2 is greater than the thickness of the insertion piece 204. At the same time, the opening degree of the guiding port is greater than the width of the insertion piece 204. After such a setting, when the insertion piece 204 is inserted into the guiding channel, there is a relatively large clearance, reducing the difficulty of inserting and turning the insertion piece 204; as the insertion piece 204 continues to approach the slot 2031 along the guiding channel, both sides of the insertion piece 204 will be guided by the guiding part 2022 and the bending part on the stopper 205 to perform vertical ( Figure 1 viewpoint) correction; in addition, under the action of the correction part 2021, the front and back ( Figure 1 viewpoint) of the insertion piece 204 can also be corrected so that the insertion piece 204 can smoothly enter the slot 2031.

[0057] As a further solution of the present utility model, inclined positioning parts 2032 are formed on both sides of the end of the slot 2031, and the end of the insertion piece 204 also has a pointed head part 2041.

[0058] During the process of inserting the insertion piece 204 into the slot 2031, it is first basically aligned with the slot 2031 under the guiding action of the guiding part 2022, the stopper 205, and the correction part 2021; as the insertion piece 204 continues to be inserted, and when the insertion piece 204 is about to enter the slot 2031, further correction is made by using the pointed head part 2041 and the positioning part 2032, so that the insertion piece 204 can be accurately and smoothly inserted into the slot 2031.

[0059] As a further solution of the present utility model, a support rod 206 is fixed on the fixed seat 202, and a sliding hole that is slidably matched with the support rod 206 is opened on the stopper 205;

[0060] The stop structure includes a rod channel 2034 opened on the mounting member 203, a stop rod 210 is slidably arranged in the rod channel 2034, and the stop rod 210 cooperates with the stopper 205.

[0061] It should be noted that a rear end cap is formed at the end of the support rod 206, and a cap hole that cooperates with the end cap is arranged on one side of the sliding hole close to the guiding part 2022.

[0062] In the initial state, the stopper 205 is located at the end of the support rod 206. At this time, the end cap fills the cap hole, and the surface of the end cap and the stopper 205 close to the guiding part 2022 are flush, avoiding jamming when the insertion piece 204 approaches the slot 2031; in addition, by using the cooperation of the set end cap and cap hole, it can be prevented that after the insertion piece 204 is withdrawn from the guiding channel, the stopper 205 completely detaches from the support rod 206.

[0063] In addition, in the initial state, the shift lever 210 extends out of the lever channel 2034 and abuts against the side of the stopper 205 away from the guiding portion 2022. Since both sides of the stopper 205 are restricted by the shift lever 210 and the end cap respectively, the stopper 205 is completely fixed in the initial state.

[0064] As a further solution of the present utility model, the stopper structure further includes a slideway 2033 formed on the mounting member 203. The slideway 2033 extends into the slot 2031, and a push plate 207 is slidably arranged in the slideway 2033. A through column 208 is fixed on one side of the push plate 207, and the through column 208 is slidably matched with a through channel 2035 formed on the mounting member 203.

[0065] A spring 209 is sleeved on the outer periphery of the through column 208. One end of the spring 209 abuts against the push plate 207, and the other end abuts against the side wall of the slideway 2033.

[0066] A positioning cavity 2036 communicating with the slideway 2033 is further formed on the mounting member 203, and the lever channel 2034 communicates with the positioning cavity 2036. An extension portion 2071 is integrally formed on one side of the push plate 207. The extension portion 2071 is slidably matched with the positioning cavity 2036, and one end of the shift lever 210 passes through the lever channel 2034 and is fixed on the extension portion 2071.

[0067] Since the slideway 2033 extends into the slot 2031, the baffle 207 also extends into the slot 2031. During the insertion of the insert piece 204 into the slot 2031, the end of the insert piece 204 will abut against the push plate 207, and then continuing to insert the insert piece 204 will push the push plate 207 to slide along the slideway 2033 and compress the spring 209.

[0068] During the sliding of the push plate 207, the extension portion 2071 is driven to slide along the positioning cavity 2036, and then the shift lever 210 is driven to slide along the lever channel 2034. When the end of the insert piece 204 is inserted into the bottom of the slot 2031, the shift lever 210 just completely retracts into the lever channel 2034. At this time, the stopper 205 is only restricted by the end cap. Therefore, by pushing the insert piece 204 to slide upward ( Figure 1 in the perspective of

[0069] In the present utility model, through the cooperation of the slot 2031 and the insertion piece 204, the front-back direction positioning of the pin socket 201 is carried out. When the insertion piece 204 is inserted to the bottom of the slot 2031, by keeping the insertion piece 204 in contact with the bottom of the slot 2031, the left-right positioning of the pin socket 201 can be carried out; finally, by pushing the insertion piece 204 to make the end of the insertion piece 204 slide upward in contact with the bottom of the slot 2031, the docking pin socket 201 and the pin plug 301 are axially advanced while keeping the front-back, left-right orientations unchanged, which is equivalent to carrying out the docking along the Z direction after positioning in the X direction and the Y direction in space, with high accuracy and not easily causing the pin to bend, deform or break.

[0070] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic features of the present utility model, all technical solutions that can implement the present utility model in other specific forms are included in the present utility model.
