Description
Technical Field
[0001] The present invention relates to the technical field of circuit connectors, and in particular to a modular circuit connector. Background Art
[0002] Connectors are also called connectors. In China, they are also called joints and sockets. They generally refer to electrical connectors. They are devices that connect two active devices, transmit current or signals, and the male and female ends can transmit information or current after contact. They are also called connectors. On test equipment, connectors are generally installed. The current modular circuit connectors have been found to have at least the following technical problems: First, in various types of test equipment, circuit connectors need to be frequently plugged and unplugged. During the frequent disassembly and assembly of existing test connectors, the contact parts between the male and female connectors and the internal contacts are very prone to wear, which will not only increase the contact resistance and affect the stability of current transmission, but may also cause signal transmission failures and reduce the accuracy of test results. In severe cases, it may even cause the connector to fail to work properly, requiring frequent replacement of connectors, increasing testing costs and equipment downtime.
[0003] Second, in the field of testing equipment, the disassembly process of existing connectors faces many difficulties. Traditional connectors mostly use complex clips and screw fastening methods. In the compact internal space of the testing equipment, the operating space is extremely limited, and it is difficult to use tools for disassembly, which is time-consuming and labor-intensive. Some connectors have high plugging and unplugging forces and lack effective auxiliary disassembly structures. During frequent disassembly operations, technicians' hands are easily fatigued or even injured, which greatly affects the efficiency and experience of the testing work. Summary of the invention
[0004] In order to solve the above technical problems, the present invention provides a modular circuit connector to solve the above problems.

[0008] Preferably, both side ends of the female plug body are provided with a snap-in groove, both side ends of the female plug body are provided with a prying groove, the tail end of the locking plate is provided with a prying rod, and the head end of the locking plate is provided with a snap joint. When the female plug body and the male plug body are disassembled, the snap joint is separated from the two snap-in grooves provided on the female plug body, and the locking plate is rotated. The locking plate and the prying rod can easily separate the female plug body from the male plug body through the lever principle.
[0009] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the male and female connectors are worn internally, technicians do not need to disassemble the male connector body fixed on the equipment. They only need to operate multiple sets of connecting rod mechanisms and pull out the male connector along the track of the limit installation groove to replace it. Similarly, if the female connector is worn, it can also be easily removed and replaced by pulling out the limit slide bar. Compared with traditional non-detachable connectors, this design of replaceable connectors greatly reduces maintenance costs.

[0011] In the present invention, by sliding the pins in the male connector in the metal sleeve of the female connector and closely fitting with the second movable contact, the metal sleeve not only increases the contact area and reduces the contact resistance, but also enhances the stability of the connection, reduces the poor contact phenomenon caused by vibration, displacement and other factors, ensures the stable transmission of current, improves the quality of circuit connection, and provides a strong guarantee for the stable operation of the test equipment.
[0012] In the present invention, the limiting sliding bars on both sides of the female plug connector are respectively slidably installed on both sides of the inner wall of the female plug connector, and a part of the end of the limiting sliding bar is set in the prying groove opened in the female plug connector. When the prying bar is used to separate the male plug connector and the female plug connector, the prying bar will squeeze the limiting sliding bar during the tilting process. This design ensures that during the disassembly process, the female plug connector and the female plug connector always maintain a relatively stable connection state, effectively avoiding the female plug connector from accidentally falling off due to external force vibration or other factors, ensuring the normal operation of the equipment, and reducing the risk of damage and failure caused by the falling off of components.

DETAILED DESCRIPTION
[0015] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.
[0016] See also Figure 1 - Figure 8 The present invention provides a modular circuit connector, including a male plug body 21 and a female plug body 31, wherein the male plug body 21 is provided with a male plug connector 22, and a first movable contact 23 is fixedly installed at the side end of the male plug connector 22, and the first movable contact 23 contacts the wiring terminal of the male plug body 21. When the male plug connector 22 is separated from the male plug body 21, the first movable contact 23 on the male plug connector 22 will be withdrawn from the inside of the male plug body 21, thereby completing the disconnection between the first movable contact 23 and the wiring terminal of the male plug body 21, and two limit rods 24 are fixedly installed on the male plug connector 22, and the two limit rods 24 are used to limit the male plug connector 22, and two limit installation grooves 26 are provided in the male plug body 21, and the limit rod 24 is slidably installed in the limit installation groove 26 provided in the male plug body 21; The female plug body 31 is provided with a female plug connector 37, and both side ends of the female plug connector 37 are provided with limit slide bars 38. 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 body 31. A second movable contact 35 is provided in the female plug connector 37, and the second movable contact 35 contacts with the wiring terminal on the female plug body 31. When the female plug body 31 and the female plug connector 37 are separated, the second movable contact 35 in the female plug connector 37 will be pulled out from the inside of the female plug body 31. A metal sleeve 36 is provided on the second movable contact 35, and the metal sleeve 36 is used to strengthen the stability of the connection between the female plug body 31 and the male plug body 21. The pins in the male plug connector 22 slide in the metal sleeve 36, and the end thereof fits with the second movable contact 35. The male plug body 21 is provided with two groups of disassembly and assembly mechanisms, both of which are used to fix the male plug body 21 and the female plug body 31. The male plug body 21 is provided with four groups of connecting rod mechanisms, all of which are used to fix the male plug connector 22 on the male plug body 21, and each group of disassembly and assembly mechanisms is respectively connected to the two groups of connecting mechanisms; In this embodiment, Figure 3 , Figure 6 As shown, the disassembly and assembly mechanism includes a locking plate 11, on which a limiting rotating shaft 12 is provided, and the limiting rotating shaft 12 is rotatably installed on the locking plate 11, and the limiting rotating shaft 12 is limitedly slidably installed on the side end of the male plug-in body 21, and when the limiting rotating shaft 12 is installed, the limiting plates at the upper and lower ends are respectively located at the upper and lower ends of the locking plate 11, and the limiting rotating shaft 12 is limited so that the limiting rotating shaft 12 can only move back and forth in the male plug-in body 21, and two connecting round rods 13 are fixedly installed on the limiting rotating shaft 12, and the two connecting round rods 13 are both slidably installed on the male plug-in body 21. At the side ends of the plug-in body 21, the side ends of the two connecting round rods 13 are fixedly installed with U-shaped clamping blocks 14. Since the U-shaped clamping block 14 is U-shaped and has protruding blocks at both ends of the U-shape, it can be clamped in the male plug-in body 21, thereby fixing the limiting rotating shaft 12 and the locking plate 11. When the male plug connector 22 needs to be disassembled, the U-shaped clamping block 14 and the male plug-in body 21 are in a separated state. When the male plug connector 21, the male plug connector 22 and the female plug body 31 are connected, the U-shaped clamping block 14 and the male plug body 21 are in a closed and fixed state.
[0017] In this embodiment, Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, the connecting rod mechanism includes an L-shaped connecting rod 15, and the L-shaped connecting rod 15 is fixedly installed on the limiting rotating shaft 12. The side end of the L-shaped connecting rod 15 is provided with a double-headed connecting rod 16, and the double-headed connecting rod 16 is provided with a moving block 17. 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 hinged through a rotating shaft. The two side ends of the male plug-in body 21 are provided with limiting sliding grooves 25. The two sets of connecting rod mechanisms are respectively slidably installed in the two limiting sliding grooves 25 provided in the male plug-in body 21. When the limiting rotating shaft 12 is moving, 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-head connecting rod 16 and the moving block 17, the moving block 17 can translate in the limiting sliding groove 25 provided in the male plug-in body 21, thereby pushing the limiting rod 24 in the limiting installation groove 26 provided in the male plug-in body 21, and limiting and fixing the limiting rod 24 in the limiting installation groove 26 provided in the male plug-in body 21, thereby fixing the male plug connector 22, and after the movement of the four groups of connecting rod mechanisms is completed, the U-shaped clamping blocks 14 in the two groups of disassembly and assembly mechanisms are synchronously clamped with the male plug-in body 21.
[0018] In this embodiment, Figure 1 , Figure 2 and Figure 5 As shown, both side ends of the female plug body 31 are provided with a snap-in groove 32, and both side ends of the female plug body 31 are provided with a prying groove 34. When the male plug body 21 is connected to the female plug body 31, the protruding part of the prying rod 18 at the rear of the buckle locking plate 11 is installed in the prying groove 34 opened in the female plug body 31, and after the male plug body 21 and the female plug body 31 are completely closed and connected, the protruding part of the snap lock plate 11 The head portion of the snap joint 19 is snapped into the snap groove 34 opened in the female plug body 31. 2, at this time, the female plug body 31 is connected to the male plug body 21. When it is necessary to disassemble the female plug body 31 and the male plug body 21, first separate the two card joints 19 from the two card grooves 32 opened in the female plug body 31, and then rotate the lock plate 11. At this time, the lock plate 11 and the pry bar 18 can easily separate the female plug body 31 from the male plug body 21 through the lever principle, avoiding the inconvenience of disassembly caused by the interface between the female plug body 31 and the male plug body 21 being too tight.
[0019] Since a portion of the end of the limiting slide bar 38 is arranged in the prying groove 34 opened in the female plug body 31, the limiting slide bar 38 will be squeezed together when the prying bar 18 is tilted up, thereby preventing the female plug connector 37 from falling off from the female plug body 31 when the female plug body 31 and the male plug body 21 are separated. When the female plug connector 37 needs to be disassembled separately, it only needs to be pulled out forcefully.
[0020] Working principle: 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.
[0021] 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.
[0022] 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.
[0023] 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.
[0024] 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.
[0025] In the present invention, by arranging a pry bar 18 at the rear end of the buckle lock plate 11, when the male plug body 21 and the female plug body 31 are disassembled, it is only necessary to separate the clamping joint 19 from the clamping groove 32 of the female plug body 31, and then rotate the buckle lock plate 11, and the pry bar 18 can easily pry the male plug body 21 and the female plug body 31 apart by using the lever principle. This design greatly reduces the effort required for disassembly, is simple and convenient to operate, effectively avoids the disassembly problem caused by the over-tight interface, and reduces the labor intensity of the operator.
[0026] In the present invention, by sliding the pins in the male connector 22 in the metal sleeve 36 of the female connector 37 and closely fitting with the second movable contact 35, the metal sleeve 36 not only increases the contact area and reduces the contact resistance, but also enhances the stability of the connection, reduces the poor contact caused by vibration, displacement and other factors, ensures the stable transmission of current, improves the quality of circuit connection, and provides a strong guarantee for the stable operation of the test equipment.
[0027] In the present invention, the limiting slide bars 38 on both sides of the female plug connector 37 are respectively slidably installed on both sides of the inner wall of the female plug body 31, and a part of the end of the limiting slide bar 38 is set in the prying groove 34 opened in the female plug body 31. When the pry bar 18 is used to separate the male plug body 21 and the female plug body 31, the pry bar 18 will squeeze the limiting slide bar 38 during the lifting process. This design ensures that during the disassembly process, the female plug connector 37 and the female plug body 31 always maintain a relatively stable connection state, effectively avoiding the female plug connector 37 from accidentally falling off due to external force vibration or other factors, ensuring the normal operation of the equipment, and reducing the risk of damage and failure caused by the falling off of components.
