Description

Technical Field

[0001] This invention relates to the field of electrical connection technology, and in particular to a conductive contact connection device and method for two ports of a microgrid converged terminal. Background Technology

[0002] Microgrid systems are increasingly widely used in distributed generation, smart grids and other fields. As a core component of microgrid systems, the reliability of the conductive contact connection between the two ports of the microgrid fusion terminal directly affects the operational stability of the entire microgrid system. The two ports of the microgrid fusion terminal need to achieve conductive connection between the wires and the terminal equipment through the connection device, while meeting multiple requirements such as connection firmness and sealing protection to adapt to complex outdoor or industrial environments.

[0003] Currently, the conductive contact connection devices commonly used at the two ports of microgrid converged terminals mostly adopt a structure in which the upper conductive connection part and the lower conductive connection part cooperate and lock together. Conductive connection is achieved by inserting the contact pin into the corresponding connection unit, while relying on elastic components such as rubber pads to assist in locking and provide a certain sealing effect.

[0004] However, existing connection devices have many technical defects in practical applications. The locking process requires the lower conductive connection part to move upward and then reset. This action relies on the rebound force of the rubber pad. However, it is difficult to balance the performance of the rubber pad. Hard rubber pads have a large rebound force but the lock is difficult to press. Soft rubber pads are easy to install but have insufficient rebound force, which can easily lead to the lock coming off. Rubber pads with moderate performance cannot take into account both locking reliability and sealing performance. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a two-port conductive contact connection device and method for a microgrid converged terminal that can overcome or at least partially solve the above problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A two-port conductive contact connection device for a microgrid converged terminal includes: an upper conductive connection portion installed on the terminal equipment and a lower conductive connection portion on which wires are installed, wherein the upper conductive connection portion is connected to the lower conductive connection portion, and further includes:

[0008] A latch for mounting the lower conductive connection part onto the upper conductive connection part;

[0009] A rectangular groove is formed on the lower conductive connection portion, and the rectangular groove contains a reset component and multiple puncturing units;

[0010] An adhesive strip is installed on the upper conductive connection part, and the adhesive strip corresponds to the rectangular groove and the puncturing unit inside the rectangular groove;

[0011] When the latch installs the lower conductive connection onto the upper conductive connection, the puncturing unit punctures the adhesive strip, causing the adhesive inside to flow out and sealing the connection between the upper and lower conductive connections.

[0012] Preferably, the upper conductive connection part includes a connector and an upper connecting unit, and the lower conductive connection part includes a connector and a lower connecting unit. The upper connecting unit is provided with a plurality of contact pins for inserting into the lower connecting unit, and the lower end of the connector is threadedly connected with a sealing nut for sealing and limiting the wire.

[0013] Furthermore, the upper connecting unit is provided with multiple limiting strips on its outer side, and the lower connecting unit is provided with multiple limiting grooves corresponding to the limiting strips.

[0014] Furthermore, the outer side of the connector is provided with a rectangular contact surface, and there is a gap between the contact surface and the upper connecting unit. The width of the contact surface is the same as the width of the rectangular groove.

[0015] Furthermore, fixed rods are symmetrically connected to both sides of the upper conductive connection, and the latches are symmetrically distributed at both ends of the upper conductive connection, with one end of the latch rotatably mounted on the fixed rod. Limiting rods are symmetrically arranged on the lower conductive connection. One side of the latch is provided with a limiting part and a receiving part for limiting the limiting rod, and the end of the latch away from the limiting part is provided with a pressing part. During the locking process, when the limiting part contacts the limiting rod, the lower conductive connection gradually moves to the upper conductive connection. When the limiting rod moves to the receiving part, the lower conductive connection moves downward a small distance to complete the locking operation.

[0016] Furthermore, the reset assembly includes two elastic sheets connected within a rectangular groove, and a trapezoidal groove corresponding to the adhesive strip is formed between the two elastic sheets. When the limiting part just contacts the limiting rod, one end of the elastic sheet contacts the mating surface. The elastic sheet includes a flexible segment and a rigid segment. The flexible segment is used to connect to the bottom of the rectangular groove, and the inner side of the rigid segment is mirror-shaped.

[0017] Furthermore, a flexible rubber is connected between the elastic sheet and the inner wall of the rectangular groove.

[0018] Furthermore, the adhesive strip has a protrusion at one end away from the bonding surface, and an arc-shaped portion is symmetrically arranged at one end of the adhesive strip near the bonding surface. The arc-shaped portion forms a cavity with the elastic sheet and the bonding surface. The puncture unit includes a puncture needle fixed between two elastic sheets, and the puncture needle punctures the protrusion.

[0019] Furthermore, a thermistor is disposed inside the adhesive strip, and conductive pins are connected to the thermistor. The connector is provided with a PCB board, a power supply, and an indicator light. The conductive pins, power supply, and indicator light are all electrically connected to the PCB board. In the initial state, the adhesive inside the adhesive strip wraps around the thermistor, which maintains its initial resistance value. The control circuit on the PCB board is in an open state, and the indicator light is off. When the piercing needle pierces the protrusion of the adhesive strip, the adhesive inside the adhesive strip flows out. After the thermistor is freed from the adhesive wrapping, the heat dissipation conditions of the environment change, causing the resistance value of the thermistor to change. The PCB board collects the resistance signal of the thermistor in real time through the conductive pins. After recognizing that the resistance signal reaches a preset threshold, the control circuit on the PCB board conducts the loop between the power supply and the indicator light, causing the power supply to output operating current to the indicator light, and the indicator light illuminates.

[0020] A method for conductive contact connection between two ports of a microgrid converged terminal mainly includes the following steps:

[0021] Step 1: Attach the lower conductive connector to the upper conductive connector;

[0022] Step 2: Install the lower conductive connector onto the upper conductive connector using the latch, and limit the lower conductive connector.

[0023] Step 3: Pierce the adhesive strip in the piercing unit and squeeze out some adhesive during the locking process. After locking is completed, the lower conductive connection part is reset under the action of the reset component.

[0024] Step 4: Fill and seal the corresponding connection areas of the upper and lower conductive connections with adhesive.

[0025] Compared with the prior art, the present invention provides a two-port conductive contact connection device for a microgrid converged terminal, which has the following advantages:

[0026] 1. The two-port conductive contact connection device of this microgrid converged terminal, by simultaneously pressing the pressing parts of the two latches, when the limiting part contacts the limiting rod, one end of the reset component contacts the mating surface. Then, by continuing to press the pressing part of the latch, the lower conductive connection part moves upward, the reset component receives compression deformation and stores energy. When the limiting rod is placed in the receiving part, the potential energy of the reset component drives the lower conductive connection part to move downward and tighten the latch. The adhesive in the adhesive strip flows out and flows along the inner wall of the reset component to the gap to fill it, thereby achieving all-round sealing. The rebound force provided by the reset component can effectively prevent the latch from falling off. In addition, the adhesive flowing out of the adhesive strip, together with the compression of the reset component, achieves all-round filling, thereby effectively improving its sealing effect and preventing the internal conductive components from being damp and corroded.

[0027] 2. The conductive contact connection device at both ends of the microgrid fusion terminal is configured with two sets of elastic sheets. The trapezoidal groove with an outward opening is located between the two elastic sheets. On the one hand, the trapezoidal groove has a certain guiding effect, which facilitates the precise contact of the adhesive strip with the puncture unit. On the other hand, when the outward-opening elastic sheet is squeezed, it can open to both sides, which allows it to deform precisely and avoids local complete impact on the filling effect of the adhesive strip.

[0028] 3. The conductive contact connection device at both ends of the microgrid fusion terminal uses flexible rubber to fill both sides of the elastic sheet. On the one hand, it can ensure the initial sealing effect and prevent the overflow of adhesive. On the other hand, it can also be used with adhesive strips to achieve double sealing, thereby effectively improving the sealing effect and preventing moisture from corroding the conductive components.

[0029] 4. The conductive contact connection device at both ports of the microgrid fusion terminal integrates a thermistor as a detection unit within the adhesive strip. The indicator light is triggered by the change in the thermistor resistance caused by the flow of adhesive. The device also clearly defines the setting methods for the initial resistance threshold A and the resistance threshold B after installation to avoid misjudgment and ensure detection accuracy. It can also clearly observe whether the connection is accurate. The method of setting thresholds A and B is based on experimental calibration and environmental correction to ensure detection accuracy in different scenarios. The misjudgment rate is less than 1%, and the cost of using thermistors is low.

[0030] The parts of this device not described herein are the same as or can be implemented using existing technologies. The invention can effectively prevent the latch from falling off by the rebound force provided by the reset component. In addition, the glue flowing out of the adhesive strip, combined with the squeezing of the reset component, achieves all-round filling, thereby effectively improving its sealing effect and preventing the internal conductive components from being damp and corroded.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] Example: Refer to Figures 1-3 A two-port conductive contact connection device for a microgrid converged terminal includes: an upper conductive connection part 2 installed on a terminal device 1 and a lower conductive connection part 4 on which a wire 405 is installed, wherein the upper conductive connection part 2 and the lower conductive connection part 4 are connected, and further includes:

[0046] Locking buckle 3 for mounting the lower conductive connection part 4 onto the upper conductive connection part 2;

[0047] In a specific embodiment, the two-port conductive contact connection device of the terminal device 1 is configured as follows:

[0048] Reference Figures 4-6 The upper conductive connection part 2 includes a connector 201 and an upper connection unit 202, and the lower conductive connection part 4 includes a connector 401 and a lower connection unit 402. The upper connection unit 202 is provided with a plurality of contact pins 204 for inserting into the lower connection unit 402, and the lower end of the connector 401 is threadedly connected with a sealing nut 406 for sealing and limiting the wire 405.

[0049] Reference Figure 6 The upper connecting unit 202 has multiple limiting strips 203 on its outer side, and the lower connecting unit 402 has multiple limiting grooves 403 corresponding to the limiting strips 203.

[0050] During installation, the lower conductive connection part 4 is installed onto the upper conductive connection part 2 by locking with latch 3. During installation, after latch 3 is locked, the lower conductive connection part 4 needs to move upward a small distance before resetting to ensure the installation effect between the lower conductive connection part 4 and the upper conductive connection part 2. In this process, a rubber pad is usually installed on the contact surface of the lower conductive connection part 4 or the upper conductive connection part 2. The setting of the rubber pad is particularly important. If hard rubber is used, its rebound force is large, but it is difficult to press the latch 3 during installation. If soft rubber pad is used, its rebound force is small and installation is convenient, but its ability to push the lower conductive connection part 4 to press against the latch 3 is reduced, which can easily lead to disengagement. However, when a moderate rubber pad is used, its various performances cannot be optimized, so disengagement or sealing defects may occur.

[0051] Therefore, the following implementation methods can be used to solve the defects of the current connection device, which mainly include:

[0052] Reference Figure 4 , Figure 8 and Figure 9 A rectangular groove 407 is formed on the lower conductive connection part 4, and a reset component and multiple piercing units are provided in the rectangular groove 407.

[0053] The adhesive strip 6 is installed on the upper conductive connection part 2, and the adhesive strip 6 corresponds to the rectangular groove 407 and the puncturing unit in the rectangular groove 407.

[0054] When the latch 3 installs the lower conductive connection part 4 onto the upper conductive connection part 2, the puncturing unit punctures the adhesive strip 6, causing the adhesive inside to flow out and sealing the connection between the upper conductive connection part 2 and the lower conductive connection part 4.

[0055] Reference Figure 6The outer side of the connector 201 is provided with a rectangular mating surface 205, and a gap 206 is provided between the mating surface 205 and the upper connecting unit 202. The width of the mating surface 205 is the same as the width of the rectangular groove 407.

[0056] When installing the lower conductive connection part 4, first use double-sided adhesive to stick the adhesive strip 6 to the mating surface 205 of the upper conductive connection part 2, and then install the lower conductive connection part 4. The mating surface 205 enters the rectangular groove 407. The piercing unit first pierces into the adhesive strip 6, and then the reset component contacts the mating surface 205 and presses the latch 3 to lock it.

[0057] Reference Figure 7 Fixed rods 207 are symmetrically connected to both sides of the upper conductive connection part 2. Locking buckles 3 are symmetrically distributed at both ends of the upper conductive connection part 2, and one end of the locking buckle 3 is rotatably mounted on the fixed rod 207. Limiting rods 404 are symmetrically arranged on the lower conductive connection part 4. A limiting part 303 and a receiving part 302 for limiting the limiting rod 404 are provided on one side of the locking buckle 3. A pressing part 301 is provided at the end of the locking buckle 3 away from the limiting part 303. During the locking process of the locking buckle 3, when the limiting part 303 contacts the limiting rod 404, the lower conductive connection part 4 gradually moves to the upper conductive connection part 2. When the limiting rod 404 moves to the receiving part 302, the lower conductive connection part 4 moves downward a small distance to complete the locking work.

[0058] During the locking process, the pressing parts 301 of both locking buckles 3 are pressed simultaneously. When the limiting part 303 contacts the limiting rod 404, one end of the reset component contacts the mating surface 205. Then, the pressing part 301 of the locking buckle 3 is pressed again. At this time, the lower conductive connection part 4 moves upward, the reset component is subjected to compression deformation and stores energy. When the limiting rod 404 is placed in the receiving part 302, the potential energy of the reset component drives the lower conductive connection part 4 to move downward and press against the locking buckle 3. The glue in the adhesive strip 6 flows out and flows along the inner wall of the reset component to the gap to fill it, thereby achieving an all-round seal. The rebound force provided by the reset component can effectively prevent the locking buckle 3 from falling off. In addition, the glue flowing out of the adhesive strip 6, combined with the compression of the reset component, achieves all-round filling, thereby effectively improving its sealing effect and preventing the internal conductive components from being damp and corroded. Since a single-component silicone adhesive can be used in the adhesive strip 6, it will still have a certain elasticity after curing, so it does not affect the disassembly and maintenance of the lower conductive connection part 4 in subsequent use.

[0059] Reference Figures 10-12In practical applications, in order to facilitate the removal of the cured glass glue during disassembly and to facilitate the precise contact of the adhesive strip 6 with the puncture unit, the following implementation method can be adopted: The reset assembly includes two elastic pieces 5 connected in the rectangular groove 407, and a trapezoidal groove 502 corresponding to the adhesive strip 6 is formed between the two elastic pieces 5. When the limiting part 303 just contacts the limiting rod 404, one end of the elastic piece 5 contacts the bonding surface 205.

[0060] Two sets of elastic sheets 5 are provided, with trapezoidal grooves 502 with outward openings located between the two elastic sheets 5. The trapezoidal grooves 502 have a certain guiding effect, which makes it easy for the adhesive strip 6 to accurately contact the puncture unit. On the other hand, when the outward-opening elastic sheets 5 are squeezed, they can open to both sides, so that they can deform accurately and avoid local complete impact on the filling effect of the adhesive strip 6.

[0061] When disassembling the lower conductive connection part 4, the latch 3 is opened. At this time, the elastic pieces 5 on both sides of the adhesive strip 6 are separated from the adhesive strip 6. Then, when the lower conductive connection part 4 is removed, the adhesive strip 6 will be fixed on the bonding surface 205, which makes it easy to remove the cured adhesive strip 6. When the lower conductive connection part 4 needs to be reinstalled during maintenance or replacement, a new adhesive strip 6 needs to be pasted.

[0062] A flexible rubber 501 is connected between the elastic sheet 5 and the inner wall of the rectangular groove 407.

[0063] Flexible rubber 501 is filled on both sides of the elastic sheet 5. On the one hand, it can ensure the initial sealing effect and prevent the overflow of glass glue. On the other hand, it can also work with the glass glue strip 6 to achieve double sealing, thereby effectively improving its sealing effect and preventing moisture from corroding the conductive components.

[0064] The adhesive strip 6 has a protrusion 602 at one end away from the bonding surface 205, and an arc-shaped part 601 is symmetrically arranged at the other end of the adhesive strip 6 near the bonding surface 205. The arc-shaped part 601 forms a cavity with the elastic sheet 5 and the bonding surface 205. The puncture unit includes a puncture needle 503 fixed between the two elastic sheets 5. The puncture needle 503 punctures the protrusion 602.

[0065] The volume of the protrusion 602 is larger than the volume of the two cavities. The protrusion 602 ensures that a shorter piercing needle 503 can pierce into the adhesive strip 6. During the extrusion process, the end of the protrusion 602 is subjected to greater extrusion force, making it easier to pierce. The arc-shaped part 601 has a certain tolerance for error, avoiding slight misalignment when fixing the adhesive strip 6 from affecting the entire operation. In addition, it allows more adhesive to enter the cavity, thereby achieving a seal with the end face of the mating surface 205.

[0066] In another preferred embodiment, the elastic sheet 5 includes a flexible segment 504 and a rigid segment 505. The flexible segment 504 is used to connect the bottom of the rectangular groove 407, and the inner side of the rigid segment 505 is mirror-shaped.

[0067] The elastic sheet 5 is set in two sections, with one end set as a flexible section 504 and the other end set as a rigid section 505. The flexible section 504 is mainly responsible for providing rebound capability, while the rigid section 505 keeps the surface flat so that the flowing glass glue can be evenly distributed. However, when the whole elastic sheet 5 is made of the same material, it will bend when deformed. At this time, there may be different spaces between it and the glue strip 6, which will affect the uniformity of the glass glue distribution.

[0068] As another preferred embodiment of this application, further, a thermistor 7 is disposed inside the adhesive strip 6, and a conductive pin 701 is connected to the thermistor 7. A PCB board 702, a power supply 703, and an indicator light 704 are disposed on the connector 201. The conductive pin 701, the power supply 703, and the indicator light 704 are all electrically connected to the PCB board. In the initial state, the adhesive inside the adhesive strip 6 encapsulates the thermistor 7, and the thermistor 7 maintains its initial resistance value, which is a threshold value A. At this time, the control circuit on the PCB board 702 is in an open state, and the indicator light 704 is de-energized and extinguished. When the... After the piercing needle 503 pierces the protrusion 602 of the adhesive strip 6, the adhesive inside the adhesive strip 6 flows out. After the thermistor 7 is detached from the adhesive, the heat dissipation conditions of the environment change, causing the resistance of the thermistor 7 to change. If the resistance at this time reaches the threshold B, the PCB board 702 collects the resistance signal of the thermistor 7 in real time through the conductive pin 701. After recognizing that the resistance signal has reached the preset threshold, the control circuit on the PCB board 702 conducts the circuit between the power supply 703 and the indicator light 704, so that the power supply 703 outputs working current to the indicator light 704, and the indicator light 704 lights up.

[0069] Specifically, this application incorporates an integrated thermistor 7 within the adhesive strip 6 as a detection unit. The change in resistance of the thermistor 7 caused by adhesive flow triggers feedback from the indicator light 704. Furthermore, the application clearly defines the setting methods for the initial resistance threshold A and the resistance threshold B after proper installation of the thermistor 7 to avoid misjudgment and ensure detection accuracy, as detailed below:

[0070] In this embodiment, the thermistor 7 is an NTC type, model MF52-103F-3435, whose core parameter is the nominal resistance value under standard conditions at 25°C. Thermosensitive coefficient The operating temperature range is -40℃ to 85℃.

[0071] The threshold A is defined as the stable resistance value of the thermistor 7 when the adhesive strip 6 is not punctured and the adhesive completely covers the thermistor 7.

[0072] The calculation method is as follows: The resistance value of the thermistor 7 is continuously collected 10 times using the PCB board, and recorded as follows: , , ..., Then, the average value is calculated using the following formula as the threshold A. In this embodiment, the resistance value of the 10 data acquisitions is 10.1. 9.9 10.0 10.2 9.8 10.0 10.1 9.9 10.0 10.0 ,therefore: 10 .

[0073] Threshold B is defined as the stable resistance value of the thermistor after the adhesive strip is punctured and the adhesive has completely flowed out. The puncture process of the adhesive strip 6 is simulated beforehand: a puncture needle 503 is inserted into the protruding part 602 of the adhesive strip, and the adhesive filling coverage C is controlled to be 50%, 60%, 70%, 80%, 90%, and 100% respectively. Under standard conditions, the thermistor resistance values ​​corresponding to different coverage rates are collected and recorded. , , ..., Plot the fill coverage C-thermistor resistance R curve, and take the minimum resistance value when C≥90% as the basic threshold. .

[0074] In this embodiment, the resistance values ​​corresponding to different coverage rates are:

[0075] C=50% =8.5 ;

[0076] C=80% =4.2 ;

[0077] C=90% =3.0 ;

[0078] C=100% =2.8 ;

[0079] Therefore, in this embodiment, a basic threshold is taken. .0 .

[0080] Furthermore, considering the influence of actual installation environment temperature and gap deviation on resistance, a correction factor is introduced, and the final threshold B is calculated using the following formula:

[0081]

[0082] in, This represents the temperature correction factor, with a value of 0.1. / ℃, obtained by fitting the threshold value B of the thermistor 7, the resistance changes by 0.1 for every 1℃ deviation from the standard temperature. ; This indicates the actual installation ambient temperature, in °C. This represents the gap correction factor, with a value of 0.5. / mm, for every 0.1mm deviation of the connection gap from the design value, the resistance changes by 0.5. ; This indicates the installation clearance, in mm. This indicates the design gap between the connector 201 and the lower conductive connection part 4, with a value of 0.2mm.

[0083] In this application, the actual installation environment is as follows: =35℃, =0.3mm, then:

[0084] .05 .

[0085] The control circuit of PCB board 702 triggers the indicator light through the following logic:

[0086] 1. Real-time acquisition of the resistance value of the thermistor ;

[0087] 2. When When the resistance drops below threshold B, and this state lasts for 3 seconds;

[0088] 3. PCB board 702 conducts the circuit between power supply 703 and indicator light 704, and indicator light 704 lights up to indicate that the installation is in place;

[0089] 4. If the data collection time exceeds 10 seconds and the threshold B is not reached, and indicator light 704 remains off, it indicates an installation malfunction.

[0090] Specifically, in the initial state: the thermistor 7, which is coated with adhesive, has a stable resistance value at the threshold value. The PCB board 702 circuit is disconnected, and indicator light 704 goes out; during installation: pressing the latch 3 causes the piercing needle 503 to pierce the protrusion 602 on the adhesive strip 6, causing adhesive to flow out and fill the gap; during the detection triggering process: the thermistor 7 detaches from the adhesive, heat dissipation accelerates, and the resistance value drops from the threshold value. Reduce to threshold And stabilize for three seconds; feedback output process: PCB board 702 conducts the circuit, indicator light 704 lights up, and installation status feedback is completed.

[0091] In this application, the threshold and threshold The methods set are all based on experimental calibration and environmental correction in order to ensure detection accuracy in different scenarios, with a false judgment rate of less than 1%, and the use of thermistor 7 has a low cost.

[0092] This application also discloses an embodiment of a practical method, specifically a method for conductive contact connection between two ports of a microgrid converged terminal, which mainly includes the following steps:

[0093] Step 1: Attach the lower conductive connection part 4 to the upper conductive connection part 2;

[0094] Step 2: Install the lower conductive connection part 4 onto the upper conductive connection part 2 using the latch 3, and limit the lower conductive connection part 4;

[0095] Step 3: The puncture unit punctures the adhesive strip 6. During the locking process of the latch 3, some adhesive can be squeezed out. After the locking is completed, the lower conductive connection part 4 is reset under the action of the reset component.

[0096] Step 4: The adhesive is filled and sealed in the corresponding connection areas between the upper conductive connection part 2 and the lower conductive connection part 4.

[0097] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
