Description

Technical Field

[0001] This utility model relates to the field of circuit connector technology, and in particular to a circuit connector. Background Technology

[0002] Circuit connectors are electronic components used in electronic devices to connect circuits and transmit electrical signals or electromagnetic energy. They play a crucial role in modern electronic systems and are widely used in fields such as communications, computers, automobiles, industrial automation, and aerospace.

[0003] When in use, a circuit connector is used to connect a connector with pins to a device or the device's wiring. A connector with a socket is connected to the wiring by soldering. The connector with the socket end is inserted into the outside of the pins of another connector to connect the circuit. During use, if the wiring soldered to the connector is pulled, it will generate tension at the solder joint between the wiring and the connector, which can easily cause the solder joint between the wiring and the connector to loosen, affecting the connection stability of the wiring and the connector and the normal use of the connector. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when the circuit soldered to the connector is pulled during use, the solder joint between the circuit and the connector will be subjected to tension, which can easily cause the solder joint between the circuit and the connector to loosen, affecting the connection stability of the circuit and the connector and the normal use of the connector. Therefore, a circuit connector is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a circuit connector, including a head body and a plug, wherein a plurality of pins are provided on one side of the head body, a slot is provided at one end of the head body, a plurality of sockets are provided at one end of the plug, a circuit is soldered to one end of the plug, and a buffer structure is provided on the outer surface of the plug to buffer the circuit when the circuit is pulled after the circuit is connected to the plug.

[0006] The effect achieved by the above components is as follows: when using the circuit connector, insert one end of the wire into one side of the plug and solder the wire to the plug. Insert the end of the plug with the socket into the slot on one side of the head body so that the socket on the outer surface of the plug fits over the outside of the pins on the head body located inside the slot. Connect the plug to the head body to make the circuit work.

[0007] Preferably, the buffer structure includes two rectangular blocks, which are mounted on the outer surface of the plug via a convenient assembly. A rotating shaft is rotatably connected to the outer surface of the two rectangular blocks. A first coil spring is provided at one end of the rotating shaft. The two ends of the first coil spring are respectively fixedly connected to one side of the rotating shaft and the inner wall of a rectangular block. A support rod is fixedly connected to the outer surface of the rotating shaft. In the normal state, the support rod is perpendicular to the plug. A through groove is opened at the top of the support rod. A screw is threadedly connected to the top of the support rod. A pressure rod is rotatably connected to the top of the screw. The two ends of the pressure rod slide on the inner wall of the through groove.

[0008] The effect achieved by the above components is as follows: When welding the wire to one end of the plug by setting the pressure rod, the wire passes through the through groove at the top of the bracket and enters the plug for welding. After welding, the two rectangular blocks and the bracket are installed on the outer surface of the plug with the help of the convenient components. Pulling the end of the wire close to the plug causes the wire to extend the excess amount on one side of the bracket. Then, rotating the screw at the top of the bracket controls the screw to move upward on the inner wall of the bracket and pushes the pressure rod to slide upward on the inner wall of the through groove. The pressure rod presses on the outer surface of the wire to fix the wire in the position outside the bracket. When using the circuit connector, if the end of the wire away from the plug is pulled, it will pull the bracket to rotate downward through the shaft and deform the first coil spring. This will make the bending allowance of the wire on one side of the bracket tend to be straight, buffering the pulling force on the wire and preventing the pulling force from being directly transmitted to the welded joint between the wire and the plug. This will minimize the risk of the welded joint between the wire and the plug being pulled and causing it to loosen and fall off, affecting the stability of the connector during use. After the external force disappears, the first coil spring returns to its original shape and drives the shaft and the bracket to rotate in the original direction.

[0009] Preferably, the top end of the pressure rod is fixedly connected with several protruding strips, which are made of rubber.

[0010] The effect achieved by the above components is that by setting the rubber protrusions, the pressure bar is less likely to cause wear on the surface of the line when it presses against the outer surface of the line, and the fixation of the line is more stable.

[0011] Preferably, a stop block is fixedly connected to the bottom end of the rectangular block, and the stop block is located below the rotating shaft.

[0012] The effect achieved by the above components is as follows: when the line is pulled and the shaft drives the frame to rotate, the frame will rotate to a position parallel to the rectangular block and contact the top of the stop block. The stop block can limit the rotation angle of the frame, so that the frame will not continue to rotate downward and generate excessive tension at the connection between the line and the plug.

[0013] Preferably, the outer surface of the rectangular block is provided with a convenient component that allows the rectangular block and the support rod to be easily installed on the outer surface of the plug or removed from the outside of the plug.

[0014] Preferably, the convenient component includes two slots, which are fixedly connected to one side of two rectangular blocks respectively. Bolts are inserted into the inner wall of the slots, and threaded holes are opened on both sides of the outer surface of the plug. The outer surface of the bolts is threadedly connected to the inner wall of the threaded holes.

[0015] The effect achieved by the above components is as follows: When installing the rectangular blocks and the support rod, place the slots on one side of the two rectangular blocks on both sides of the outer surface of the plug, align the slots with the threaded holes on the outer surface of the plug, then insert the bolts through the slots into the threaded holes on the outer surface of the plug, rotate the bolts to make the bolts threaded into the inner wall of the threaded holes, which can fix the slots, rectangular blocks and the support rod on the outside of the plug. Rotate the bolts to disengage the bolts from the inside of the threaded holes to remove the slots and rectangular blocks.

[0016] Preferably, the plug has fastening structures on both sides, each fastening structure including a round rod rotatably connected to the inner wall of the plug. One end of the round rod is fixedly connected to a protrusion, and the outer surface of the round rod is provided with a second coil spring. The two ends of the second coil spring are fixedly connected to one side of the round rod and one side of the outer surface of the plug, respectively. The outer surface of the head body has round holes on both sides, the bottom of the inner wall of the round hole has a round groove, the inside of the round hole has a rectangular groove, and one side of the inner wall of the round groove has a retaining groove.

[0017] The effect achieved by the above components is as follows: when the plug is inserted into the slot at one end of the head body, the round rods on both sides of the plug are rotated to align the protrusions on the outer surface of the round rods with the rectangular grooves on the outer surface of the head body. At this time, the second coil spring will deform. After the round rod enters the round hole, the round rod is released, and the protrusions will move inside the rectangular grooves. When one end of the round rod abuts against the round groove, the second coil spring returns to its original shape and drives the round rod to rotate in the original direction, so that the protrusions at one end of the round rod enter the slots on one side of the round grooves. This further tightens the position of the round rod inside the round hole and the position of the plug inside the head body, improving the stability of the connection between the plug and the head body.

[0018] Preferably, an operating block is fixedly connected to the end of the round rod away from the protrusion, and the outer surface of the operating block is provided with a plurality of protrusions.

[0019] The effect achieved by the above components is that the protrusions on the outer surface of the operating block make it easier to rotate the operating block to control the rotation of the round rod and prevent the hand from slipping.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, by setting a buffer structure, when the connecting wire is connected to the plug, the connecting wire passes through the through groove on the outer surface of the frame and bends by a certain amount. When the connecting wire is pulled, the excess bending of the wire on one side of the frame tends to straighten, thus buffering the tensile force on the wire and preventing the tensile force from being directly transmitted to the solder joint between the wire and the plug. This minimizes the risk of the solder joint between the wire and the plug becoming loose and falling off due to pulling, which would affect the stability of the connector during use.

[0028] Example 1, as Figure 1 and Figure 2 As shown, a circuit connector includes a head body 1 and a plug 6. A plurality of pins 4 are provided on one side of the head body 1, and a slot 5 is provided at one end of the head body 1. A plurality of sockets are provided at one end of the plug 6, and a wire 7 is soldered to one end of the plug 6. A buffer structure 2 is provided on the outer surface of the plug 6 to buffer the wire 7 when it is pulled after being connected to the plug 6. When using the circuit connector, one end of the wire 7 is inserted into one side of the plug 6 and soldered to the plug 6. The end of the plug 6 with the sockets is inserted into the slot 5 on one side of the head body 1 so that the sockets on the outer surface of the plug 6 fit over the pins 4 located inside the slot 5 of the head body 1. The plug 6 is then connected to the head body 1 to connect the circuit.

[0029] Reference Figure 1 , Figure 2 and Figure 5 As shown in this embodiment: the buffer structure 2 includes two rectangular blocks 21. The two rectangular blocks 21 are mounted on the outer surface of the plug 6 via a convenient component 22. A rotating shaft 23 is rotatably connected to the outer surface of the two rectangular blocks 21. A first coil spring 24 is provided at one end of the rotating shaft 23. The two ends of the first coil spring 24 are fixedly connected to one side of the rotating shaft 23 and the inner wall of a rectangular block 21, respectively. A support rod 25 is fixedly connected to the outer surface of the rotating shaft 23. In the normal state, the support rod 25 is perpendicular to the plug 6. A through groove 26 is provided at the top of the support rod 25. A screw 27 is threadedly connected to the top of the support rod 25. A pressure rod 28 is rotatably connected to the top of the screw 27. The two ends of the pressure rod 28 slide on the inner wall of the through groove 26. By setting the pressure rod 28, when welding the wire 7 to one end of the plug 6, the wire 7 passes through the through groove 26 at the top of the support rod 25 and enters the plug 6 for welding. After welding, the two rectangular blocks 21 and the support rod 25 are mounted on the plug 6 with the help of the convenient component 22. On the outer surface of plug 6, pull the end of line 7 close to plug 6 to make line 7 extend beyond the bracket 25 by an excess amount. Then rotate the screw 27 at the top of bracket 25 to control the screw 27 to move upward on the inner wall of bracket 25 and push the pressure rod 28 to slide upward on the inner wall of through groove 26. The pressure rod 28 presses against the outer surface of line 7 to fix line 7 on the outside of bracket 25. When using the circuit connector, if the end of line 7 away from plug 6 is pulled, it will pull bracket 25 to rotate downward through shaft 23 and deform the first coil spring 24, so that the excess bending of line 7 on one side of bracket 25 tends to straighten, buffering the pulling force on line 7 and preventing the pulling force from being directly transmitted to the solder joint between line 7 and plug 6. This avoids the solder joint between line 7 and plug 6 being pulled and loosened or detached, affecting the stability of the connector during use. After the external force disappears, the first coil spring 24 returns to its original shape and drives shaft 23 and bracket 25 to rotate in the original direction.

[0030] Reference Figure 2 and Figure 5 As shown in this embodiment: the top of the pressure rod 28 is fixedly connected with several protrusions 29, which are made of rubber. By setting the protrusions 29, the pressure rod 28 is less likely to cause wear on the surface of the line 7 when it presses against the outer surface of the line 7, and the fixation of the line 7 is more stable. The bottom of the rectangular block 21 is fixedly connected with a stop block 210, which is located below the rotating shaft 23. When the line 7 is pulled, the rotating shaft 23 drives the support rod 25 to rotate. When the support rod 25 rotates to a position parallel to the rectangular block 21, it will contact the top of the stop block 210. The stop block 210 can limit the rotation angle of the support rod 25, so that the support rod 25 will not continue to rotate downward and generate excessive tension at the connection between the line 7 and the plug 6.

[0031] Reference Figure 2 and Figure 5 As shown in this embodiment: the outer surface of the rectangular block 21 is provided with a convenient component 22 that allows the rectangular block 21 and the support rod 25 to be easily installed on or removed from the outer surface of the plug 6. The convenient component 22 includes two slots 221, which are respectively fixedly connected to one side of the two rectangular blocks 21. Bolts 222 are inserted into the inner wall of the slots 221. Threaded holes 223 are respectively opened on both sides of the outer surface of the plug 6. The outer surface of the bolts 222 is threadedly connected to the inner wall of the threaded holes 223. When installing the rectangular block 21 and the support rod 25, the two... The slots 221 on one side of the rectangular block 21 are respectively attached to the two sides of the outer surface of the plug 6. Align the slots 221 with the threaded holes 223 on the outer surface of the plug 6, and then insert the bolts 222 through the slots 221 into the threaded holes 223 on the outer surface of the plug 6. Rotate the bolts 222 to make the bolts 222 threadedly connected to the inner wall of the threaded holes 223. This can fix the slots 221, the rectangular block 21, and the bracket 25 on the outside of the plug 6. Rotate the bolts 222 to disengage the bolts 222 from the inside of the threaded holes 223, and the slots 221 and the rectangular block 21 can be removed.

[0032] Reference Figure 1-4 As shown in this embodiment: Fastening structures 3 are provided on both sides of the plug 6. Each fastening structure 3 includes a round rod 31, which is rotatably connected to the inner wall of the plug 6. A protrusion 35 is fixedly connected to one end of the round rod 31. A second coil spring 37 is provided on the outer surface of the round rod 31, with both ends of the second coil spring 37 fixedly connected to one side of the round rod 31 and one side of the outer surface of the plug 6, respectively. Round holes 32 are opened on both sides of the outer surface of the head body 1. A round groove 33 is opened at the bottom of the inner wall of the round hole 32. A rectangular groove 34 is opened inside the round hole 32. A slot 36 is opened on one side of the inner wall of the round groove 33. When the plug 6 is inserted into the slot 5 at one end of the head body 1, rotating the round rod 31 on both sides of the plug 6 controls the alignment of the protrusion 35 on the outer surface of the round rod 31 with the rectangular groove 34 on the outer surface of the head body 1. At this time, the second coil spring 37 will deform. After the round rod 31 enters the round hole 32, the round rod 31 will be released. The protrusion 35 will move inside the rectangular groove 34. When one end of the round rod 31 abuts against the round groove 33, the second coil spring 37 will return to its original state and drive the round rod 31 to rotate in the original direction, so that the protrusion 35 at one end of the round rod 31 enters the slot 36 on one side of the round groove 33. This further tightens the position of the round rod 31 inside the round hole 32 and the position of the plug 6 inside the head body 1, improving the stability of the connection between the plug 6 and the head body 1. The end of the round rod 31 away from the protrusion 35 is fixedly connected to the operating block 38. The outer surface of the operating block 38 is provided with several protrusions. Holding the protrusions on the outer surface of the operating block 38 makes it easier to rotate the operating block 38 to control the rotation of the round rod 31 and prevents the hand from slipping.

[0033] Working principle: When using the circuit connector, to solder one end of the wire 7 to the plug 6, the wire 7 is passed through the through slot 26 at the top of the bracket 25 into the plug 6 for soldering. After soldering, the slot blocks 221 on one side of the two rectangular blocks 21 are respectively attached to the two sides of the outer surface of the plug 6, aligning the slot blocks 221 with the threaded holes 223 on the outer surface of the plug 6. Then, the bolt 222 is inserted through the slot block 221 into the threaded hole 223 on the outer surface of the plug 6. Rotating the bolt 222 to make the bolt 222 threaded into the inner wall of the threaded hole 223 can fix the slot block 221, the rectangular block 21, and the bracket 25 to the outside of the plug 6. Pull the end of the wire 7 close to the plug 6 so that the wire 7 protrudes a little beyond the bracket 25. Then, rotate the screw 27 at the top of the bracket 25 to control the screw 27 to move upward on the inner wall of the bracket 25, pushing the pressure rod 28 to slide upward on the inner wall of the through slot 26. The pressure rod 28 presses against the outer surface of the wire 7 to secure the wire. 7. Fix the plug 6 to the outside of the bracket 25. Then insert the end of the plug 6 with the socket into the slot 5 on one side of the head body 1 so that the socket on the outer surface of the plug 6 fits over the outside of the pin 4 of the head body 1 located in the slot 5. When inserting the plug 6, rotate the round rod 31 on both sides of the plug 6 to align the protrusion 35 on the outer surface of the round rod 31 with the rectangular groove 34 on the outer surface of the head body 1. At this time, the second coil spring 37 will deform. After the round rod 31 enters the round hole 32, release the round rod 31. The protrusion 35 will move inside the rectangular groove 34. When one end of the round rod 31 abuts against the round groove 33, the second coil spring 37 returns to its original state and drives the round rod 31 to rotate in the original direction, so that the protrusion 35 at one end of the round rod 31 enters the slot 36 on one side of the round groove 33. Further tighten the position of the round rod 31 inside the round hole 32 and the position of the plug 6 inside the head body 1. After the plug 6 is located inside the slot at one end of the head body 1, it connects with the head body 1 to connect the circuit.
