Description

Technical Field

[0001] The present invention relates to the technical field of circuit connectors, and particularly to a modular circuit connector. Background Art

[0002] A connector is also called a coupler. In China, it is also called a connector and a socket, generally referring to an electrical connector. That is, a device connecting two active devices, transmitting current or signals. The male end and the female end can transmit messages or current after contact, and it is also called a connector. Generally, a connector is provided on a test device;

[0003] Currently, for the existing modular circuit connectors, at least the following technical problems are found:

[0004] First, in various test devices, the circuit connector needs to be frequently plugged and unplugged. During the frequent disassembly and assembly process of the existing test connectors, the contact parts between the male plug connector and the female plug connector and the internal contacts are extremely prone to wear. This will not only increase the contact resistance, affect the stability of current transmission, but also may cause signal transmission failures, reduce the accuracy of test results, and in severe cases, even make the connector unable to work properly, requiring frequent replacement of the connector, increasing the test cost and equipment downtime.

[0005] Second, in the field of test devices, the disassembly process of the existing connectors faces many problems. Traditional connectors mostly use complex snap and screw fastening methods. In the compact internal space of the test device, the operating space is extremely limited, and it is difficult to operate when using tools for disassembly, which is time-consuming and laborious. For some connectors, the plugging and unplugging force is relatively large, and there is a lack of an effective auxiliary disassembly structure. During the frequent disassembly operations, technicians' hands are prone to fatigue and even injury, greatly affecting the efficiency and experience of the test work. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a modular circuit connector to solve the above problems.

[0007] A modular circuit connector includes a male plug connector and a female plug connector. The male plug connector is provided with a male plug head. A first movable contact is fixedly installed at the side end of the male plug head. Two limit rods are fixedly installed on the male plug connector, and the two limit rods are used to limit the male plug head. Two limit installation grooves are opened in the male plug connector, and the limit rods are slidably installed in the limit installation grooves opened in the male plug connector. The female plug connector is provided with a female plug head. Limit sliding rods are provided at both side ends of the female plug head, and the limit sliding rods at both side ends of the female plug head are respectively slidably installed on both sides of the inner wall of the female plug connector. A second movable contact is provided in the female plug head, and a metal sleeve is provided on the second movable contact. The pins in the male plug head slide in the metal sleeve, and their ends are in contact with the second movable contact. Two sets of disassembly and assembly mechanisms are provided on the male plug connector, and both sets of disassembly and assembly mechanisms are used to fix the male plug connector and the female plug connector. Four sets of link mechanisms are provided on the male plug connector, and all four sets of link mechanisms are used to fixedly install the male plug head on the male plug connector. At the same time, each set of disassembly and assembly mechanisms is respectively connected to two sets of connection mechanisms.

[0008] Preferably, the disassembly and assembly mechanism includes a latch plate. A limit rotating shaft is provided on the latch plate, and the limit rotating shaft is rotatably installed through the latch plate. The limit rotating shaft is slidably installed in a limited manner at the side end of the male plug connector. Two connecting round rods are fixedly installed on the limit rotating shaft, and both of the two connecting round rods are slidably installed through the side end of the male plug connector;

[0009] Among them, U-shaped clamping blocks are fixedly installed at the side ends of the two connecting round rods.

[0010] Preferably, the link mechanism includes an L-shaped link. The L-shaped link is fixedly installed on the limit rotating shaft. A double-headed link is provided at the side end of the L-shaped link, and a moving block is provided on the double-headed link. The L-shaped link and the double-headed link, as well as the double-headed link and the moving block, are all hinged through rotating shafts. Limit sliding grooves are opened at both side ends of the male plug connector, and the two sets of link mechanisms are respectively slidably installed in the two limit sliding grooves opened in the male plug connector.

[0011] Preferably, clamping grooves are opened at both side ends of the female plug connector, and prying grooves are opened at both side ends of the female plug connector. A prying rod is provided at the tail end of the latch plate, and a clamping head is provided at the head end of the latch plate. When disassembling the female plug connector and the male plug connector, the clamping head is separated from the two clamping grooves opened in the female plug connector, and the latch plate is rotated. The latch plate and the prying rod use the lever principle to easily separate the female plug connector and the male plug connector.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, when the male plug connector and the female plug connector are worn inside, technicians do not need to disassemble the male plug body fixed on the device. They only need to operate on multiple link mechanisms, pull out the male plug connector along the track of the limit installation groove, and then it can be replaced. Similarly, if the female plug connector is worn, it can also be easily removed and replaced by pulling out the limit slide rod. This design of replaceable plug connectors greatly reduces the maintenance cost compared with traditional non-detachable connectors. At the same time, the method of quickly replacing the plug connector significantly reduces the equipment downtime and improves the overall working timeliness.

[0014] In the present invention, by setting a pry bar at the end of the latch plate, when disassembling the male and female plug bodies, only need to separate the card joint from the card slot of the female plug body, and then rotate the latch plate, the pry bar can easily pry open the male and female plug bodies by using the lever principle. This design greatly reduces the force required for disassembly, is simple and convenient to operate, effectively avoids the disassembly problems caused by too tight interfaces, and reduces the labor intensity of operators.

[0015] In the present invention, by sliding the pins in the male plug connector inside the metal sleeve of the female plug connector and closely fitting with the second movable contact, the metal sleeve not only increases the contact area, reduces the contact resistance, but also enhances the connection stability, reduces the poor contact phenomenon caused by factors such as vibration and displacement, ensures the stable transmission of current, improves the circuit connection quality, and provides a strong guarantee for the stable operation of the test equipment.

[0016] In the present invention, by sliding the limit slide rods on both sides of the female plug connector on both sides of the inner wall of the female plug body respectively, and a part of the end of the limit slide rod is arranged in the pry groove opened on the female plug body, when using the pry bar to separate the male plug body from the female plug body, the pry bar will squeeze the limit slide rod together during the prying process. This design makes the female plug connector and the female plug body always maintain a relatively stable connection state during the disassembly process, effectively avoids the accidental detachment of the female plug connector due to external vibration or other factors, ensures the normal operation of the equipment, and reduces the damage and failure risks caused by the detachment of components.

Specific embodiments

[0026] The following further describes the embodiments of the present invention in detail with reference to the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0027] Please refer to Figure 1 - Figure 8 , the present invention provides a modular circuit connector, including a male plug-in body 21 and a female plug-in body 31. A male plug-in head 22 is provided on the male plug-in body 21. A first movable contact 23 is fixedly installed on the side end of the male plug-in head 22. The first movable contact 23 contacts the wiring end of the male plug-in body 21. When the male plug-in head 22 is separated from the male plug-in body 21, the first movable contact 23 on the male plug-in head 22 will be withdrawn from the inside of the male plug-in body 21, thereby completing the disconnection of the first movable contact 23 from the wiring end of the male plug-in body 21. Two limit rods 24 are fixedly installed on the male plug-in head 22. The two limit rods 24 are used to limit the male plug-in head 22. Two limit installation grooves 26 are opened in the male plug-in body 21. The limit rods 24 are slidably installed in the limit installation grooves 26 opened in the male plug-in body 21;

[0028] The female plug-in body 31 is provided with a female plug connector 37. Limit slide bars 38 are provided at both side ends of the female plug connector 37. The limit slide bars 38 at both side ends of the female plug connector 37 are respectively slidably installed on both sides of the inner wall of the female plug-in body 31. A second movable contact 35 is provided inside the female plug connector 37. The second movable contact 35 is in contact with the wiring terminal on the female plug-in body 31. When the female plug-in body 31 is separated from the female plug connector 37, the second movable contact 35 inside the female plug connector 37 will be drawn out from the inside of the female plug-in body 31. A metal sleeve 36 is provided on the second movable contact 35. The metal sleeve 36 is used to strengthen the stability of the connection between the female plug-in body 31 and the male plug-in body 21. The pins inside the male plug connector 22 slide inside the metal sleeve 36, and their ends are in contact with the second movable contact 35;

[0029] Two disassembly and assembly mechanisms are provided on the male plug-in body 21. Both disassembly and assembly mechanisms are used to fix the male plug-in body 21 and the female plug-in body 31. Four link mechanisms are provided on the male plug-in body 21. All four link mechanisms are used to fixedly install the male plug connector 22 on the male plug-in body 21. At the same time, each disassembly and assembly mechanism is respectively connected to two connection mechanisms;

[0030] In this embodiment, as Figure 3 、 Figure 6 shown, the disassembly and assembly mechanism includes a buckle plate 11. A limit rotating shaft 12 is provided on the buckle plate 11. The limit rotating shaft 12 is rotatably installed through the buckle plate 11. The limit rotating shaft 12 is slidably installed at the side end of the male plug-in body 21 in a limited manner. When the limit rotating shaft 12 is installed, the limit plates at its upper and lower ends are respectively located at the upper and lower ends of the buckle plate 11 to limit the limit rotating shaft 12, so that the limit rotating shaft 12 can only move back and forth inside the male plug-in body 21. Two connecting round bars 13 are fixedly installed on the limit rotating shaft 12. Both of the two connecting round bars 13 are slidably installed through the side end of the male plug-in body 21. A U-shaped clamping block 14 is fixedly installed at the side ends of the two connecting round bars 13. Since the shape of the U-shaped clamping block 14 is U-shaped and raised blocks are provided inside the two end parts of its U shape, it can be clamped inside the male plug-in body 21, thereby playing a role in fixing the limit rotating shaft 12 and the buckle plate 11. When it is necessary to disassemble the male plug connector 22, the U-shaped clamping block 14 is in a separated state from the male plug-in body 21. When the male plug-in body 21, the male plug connector 22 and the female plug-in body 31 are connected, the U-shaped clamping block 14 is in a closed and fixed state with the male plug-in body 21.

[0031] In this embodiment, as Figure 1 、 Figure 4 、 Figure 7 and Figure 8As shown, the linkage mechanism includes an L-shaped connecting rod 15, which is fixedly installed on the limit rotating shaft 12. A double-headed connecting rod 16 is provided at the side end of the L-shaped connecting rod 15, and a moving block 17 is provided on the double-headed connecting rod 16. The L-shaped connecting rod 15 and the double-headed connecting rod 16, as well as the double-headed connecting rod 16 and the moving block 17, are all hinged by a rotating shaft. The two side ends of the male plug-in body 21 are provided with limit sliding grooves 25, and the two linkage mechanisms are respectively slidably installed in the two limit sliding grooves 25 opened on the male plug-in body 21. When the limit rotating shaft 12 moves, it will drive the L-shaped connecting rod 15 to move. Through the multi-link mechanism among the L-shaped connecting rod 15, the double-headed connecting rod 16 and the moving block 17, the moving block 17 can be translated in the limit sliding groove 25 opened on the male plug-in body 21, so as to push the limit rod 24 in the limit installation groove 26 opened on the male plug-in body 21, and limit and fix the limit rod 24 in the limit installation groove 26 opened on the male plug-in body 21, thereby fixing the male plug 22. And after the four linkage mechanisms are moved, the U-shaped clamping blocks 14 in the two disassembly and assembly mechanisms are clamped with the male plug-in body 21 synchronously.

[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 5 shown, clamping grooves 32 are opened on both side ends of the female plug-in body 31, and pry grooves 34 are opened on both side ends of the female plug-in body 31. When the male plug-in body 21 is connected to the female plug-in body 31, the pry bar 18 on the protruding part of the tail of the buckle plate 11 is installed in the pry groove 34 opened on the female plug-in body 31. After the male plug-in body 21 and the female plug-in body 31 are completely closed and connected, the clamping head 19 on the protruding part of the head of the buckle plate 11 is clamped in the clamping groove 32 opened on the female plug-in body 31. At this time, the female plug-in body 31 and the male plug-in body 21 are connected. When it is necessary to disassemble the female plug-in body 31 and the male plug-in body 21, first separate the two clamping heads 19 from the two clamping grooves 32 opened on the female plug-in body 31, and then rotate the buckle plate 11. At this time, the buckle plate 11 and the pry bar 18 can easily separate the female plug-in body 31 and the male plug-in body 21 through the lever principle, avoiding the inconvenience of disassembly caused by the too tight interface between the female plug-in body 31 and the male plug-in body 21.

[0033] Since a part of the end of the limit sliding rod 38 is arranged in the pry groove 34 opened on the female plug-in body 31, when the pry bar 18 is lifted, the limit sliding rod 38 will be squeezed at the same time, so as to avoid the female plug 37 falling off from the female plug-in body 31 when the female plug-in body 31 and the male plug-in body 21 are separated. When it is necessary to separately disassemble the female plug 37, just pull out the female plug 37 forcefully.

[0034] Working principle:

[0035] The first step is to align the male connector 21 and the female connector 31 so that the pins in the male connector 22 correspond to the metal sleeve 36 in the female connector 37. At the same time, ensure that the limiting slide bars 38 at both sides of the female connector 31 are respectively located in the slide grooves on both sides of the inner wall of the female connector 31, and the limiting rod 24 on the male connector 22 is located in the limiting installation groove 26 of the male connector 21, and prepare for connection.

[0036] In the second step, the movement of the limiting shaft 12 drives the connecting round rod 13 and the U-shaped clamping block 14 to move, and the U-shaped clamping block 14 is clamped into the male plug-in body 21. At the same time, the movement of the limiting shaft 12 drives the L-shaped connecting rod 15 to move. Through the connecting rod mechanism between the L-shaped connecting rod 15, the double-headed connecting rod 16 and the moving block 17, the moving block 17 is translated in the limiting slide groove 25, pushing the limiting rod 24, and fixing the male plug connector 22 on the male plug-in body 21.

[0037] The third step is to push the male connector 21 and the female connector 31 closer to each other, and gradually insert the pins in the male connector 22 into the metal sleeve 36 until the pin ends of the male connector 22 fit with the second movable contact 35 to achieve circuit connection. During the connection process, the pry bar 18 at the tail of the locking plate 11 on the male connector 21 enters the pry groove 34 opened in the female connector 31.

[0038] The fourth step, when disassembly is required, first separate the snap connector 19 from the snap groove 32 opened on the female plug body 31, then rotate the locking plate 11, and use the lever principle of the locking plate 11 and the pry bar 18 to easily separate the female plug body 31 from the male plug body 21. When the pry bar 18 is tilted, it will squeeze the limiting slide bar 38 to prevent the female plug connector 37 from falling off from the female plug body 31. If you want to disassemble the female plug connector 37 alone, just pull it out with force.

[0039] In the present invention, when the male connector 22 and the female connector 37 are worn internally, the technician does not need to disassemble the male connector body 21 fixed to the equipment, but only needs to operate the multiple sets of connecting rod mechanisms to pull out the male connector 22 along the track of the limit installation groove 26 for replacement. Similarly, if the female connector 37 is worn, it can also be easily removed and replaced by pulling out the limit slide bar 38. Compared with the traditional non-detachable connector, this replaceable connector design greatly reduces the maintenance cost. At the same time, the quick replacement of the connector greatly reduces the equipment downtime and improves the timeliness of the overall work.

[0040] In the present invention, by providing a pry bar 18 at the end of the latch plate 11, when disassembling the male connector 21 and the female connector 31, it is only necessary to separate the engaging head 19 from the engaging groove 32 of the female connector 31, and then rotate the latch plate 11. The pry bar 18 can easily pry open the male connector 21 and the female connector 31 by using the lever principle. This design greatly reduces the force required for disassembly, is simple and convenient to operate, effectively avoids the disassembly problems caused by too tight interfaces, and reduces the labor intensity of the operator.

[0041] In the present invention, by sliding the pins in the male plug connector 22 within the metal sleeve 36 of the female plug connector 37 and closely fitting with the second movable contact 35, the metal sleeve 36 not only increases the contact area, reduces the contact resistance, but also enhances the connection stability, reduces the poor contact phenomenon caused by factors such as vibration and displacement, ensures the stable transmission of current, improves the circuit connection quality, and provides a strong guarantee for the stable operation of the test equipment.

[0042] In the present invention, by slidably installing the limiting slide rods 38 on both sides of the female plug connector 37 on both sides of the inner wall of the female connector 31 respectively, and a part of the end of the limiting slide rod 38 is arranged in the pry groove 34 opened in the female connector 31, when using the pry bar 18 to separate the male connector 21 and the female connector 31, the pry bar 18 will squeeze the limiting slide rod 38 together during the prying process. This design enables the female plug connector 37 and the female connector 31 to always maintain a relatively stable connection state during the disassembly process, effectively avoiding the accidental detachment of the female plug connector 37 due to external vibration or other factors, ensuring the normal operation of the equipment, and reducing the damage and failure risks caused by the detachment of components.

[0043] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.
