Description

Technical Field

[0001] The present application relates to the field of circuit plugging, and in particular to a plug. Background Art

[0002] Plugs are widely used in modern machinery, electronics and other fields. Where there is electricity, plugs are basically indispensable. With the development of modern industry, plugs need to meet some practical needs in addition to ensuring basic connection reliability. Different application sites have different application requirements, ensuring the plug-in stability, etc. However, the connectors on the market currently have poor variability after product finalization, and cannot be selectively used according to the application site. In addition, the existing rectangular connectors are complicated to assemble and the locking is unreliable.

[0003] The plugs currently on the market generally include metal plug-in plates for transmitting current. After the terminals of the socket are inserted into the plug, they abut against the plug-in plates. The plug-in stability is ensured by the tight contact of the plug-in plates against both sides of the terminals.

[0004] With regard to the above-mentioned related technologies, the stability of the plug connection is ensured only by the plug-in plate pressing against both sides of the terminal. During use, the connection state between the plug-in plate and the plug is easily unstable, thereby causing poor contact. Summary of the invention

[0005] In order to ensure that the connection between the plug board and the plug is stable and in good contact, the present application provides a plug.

[0006] The present application provides a plug that adopts the following technical solution:

[0007] A plug comprises a connecting seat and a plug-in seat, wherein the plug-in seat is fixedly arranged on the connecting seat, the plug-in seat is provided with a plug-in hole which is arranged through the connecting seat, a plug-in sheet is fixedly arranged inside the connecting seat, two clamping blocks are slidingly fitted on the top of the connecting seat, a rotating sleeve is rotatably arranged between the plug-in seat and the connecting seat, a clamping protrusion is fixedly arranged inside the rotating sleeve, when the socket is plugged and fitted with the plug and the clamping protrusion rotates with the rotating sleeve to abut against the two clamping blocks, the two clamping blocks slide toward the direction close to the terminal respectively and abut against the two sides of the terminal respectively.

[0008] By adopting the above technical solution, when the terminal passes through the plug-in hole and is plugged into the plug-in piece, the rotating sleeve located between the plug-in seat and the connecting seat is rotated, and the rotation of the rotating sleeve drives the tightening protrusion to rotate, and the rotation of the tightening protrusion drives the two tightening blocks to slide toward the terminal until the two tightening blocks tighten and fix the terminal. The setting of the tightening blocks makes the connection between the plug board and the plug more stable, which improves the stability of the plug connection by only tightening the plug-in piece on both sides of the terminal. During use, the connection state between the plug board and the plug is prone to instability, which leads to poor contact.

[0009] Optionally, rubber blocks are fixedly provided on both sides of the two pressing blocks facing the terminal pressing positions.

[0010] By adopting the above technical solution and the provision of the rubber block, the two pressing blocks can press the terminals more stably, thus making the practicability better.

[0011] Optionally, a return spring is provided between the two abutting blocks, and two ends of the return spring are respectively fixedly connected to the two abutting blocks.

[0012] By adopting the above technical solution, when the pressing protrusion is separated from the abutment with the two pressing blocks, the two pressing blocks move away from each other through the reset spring, which facilitates the insertion of the terminal into the plug-in sheet and improves practicality.

[0013] Optionally, a stop block is fixedly provided at the bottom of the socket, and a slider is slidably engaged with the tops of the two clamping blocks. A clamping spring is provided between the slider and the stop block, one end of the clamping spring is fixedly connected to the stop block, and the other end of the clamping spring is fixedly connected to the slider. When the terminal is plugged into the connector, the slider is clamped to one side of the terminal by the elastic force of the clamping spring.

[0014] By adopting the above technical solution, when the terminal is plugged into the plug-in piece, the clamping spring is pressed between the slider and the stopper, and the slider presses one end of the terminal through the elastic force of the clamping spring, making the plug-in fit between the terminal and the plug more stable.

[0015] Optionally, a slope is provided on the top of the sliding block, and the slope is inclined from top to bottom from one end close to the pressing spring to one end away from the pressing spring.

[0016] By adopting the above technical solution, when the terminal is plugged in, the top of the terminal abuts against the inclined surface of the slider, giving the inclined surface a force toward the connecting seat. Through the guidance of the inclined surface, part of the force is converted into a force toward the clamping spring, and the slider is pushed toward the direction close to the stop block until the slider is pushed away from the top of the position where the two clamping blocks are facing each other. The setting of the inclined surface makes it easier to push the slider to the top of the position where the two clamping blocks are facing each other, making it more practical.

[0017] Optionally, the connecting seat is fixedly provided with an abutment piece, the abutment piece is elastic, and a through-set abutment groove is provided at the bottom of the plug socket, the abutment piece is passed through the abutment groove, and when the socket and the plug are plugged in, the abutment piece abuts against two sides of the socket.

[0018] By adopting the above technical solution, when the socket and the plug are plugged together, the abutment sheet abuts against the two sides of the socket through its own elasticity, thereby making the plugging and matching of the socket and the plug more stable and more practical.

[0019] Optionally, a guide block is fixedly provided on the inner wall of the socket, and the length of the guide block is set along the height direction of the socket itself.

[0020] By adopting the above technical solution, when the socket and the plug are plugged in, the guide groove on the side of the socket slides with the guide block and slides along the length direction of the guide block, thereby making the plug-in connection between the plug and the socket easier through the guiding cooperation of the guide block, making it more practical.

[0021] Optionally, a dustproof seat is fixedly provided on the top of the socket, and the dustproof seat is detachably connected to a dustproof cover.

[0022] By adopting the above technical solution, when the plug is not in use, the dust cover can be detachably connected to the dust seat, so that the interior of the socket is sealed, thereby preventing dust from entering the plug, making it more practical.

[0023] Optionally, a rotation groove is provided at the bottom of the socket, and a rotation block is fixedly provided on one side of the rotation sleeve close to the socket, and the rotation block is inserted into the rotation groove and rotationally cooperates with the rotation groove.

[0024] By adopting the above technical solution, when the rotating sleeve rotates relative to the plug socket, the rotating block rotates along the rotating groove, so that the rotation of the rotating sleeve is more stable and the practicality is better.

[0025] Optionally, a sealing groove is provided at the bottom of the rotating sleeve, and a sealing ring is provided between the connecting seat and the rotating sleeve, one side of the sealing ring is snap-fitted into the sealing groove, and the other side of the sealing ring abuts against the connecting seat.

[0026] By adopting the above technical solution and setting the sealing ring, the connection between the rotating sleeve and the connecting seat is more tightly sealed, so that dust is not easy to enter the inside of the plug from the connection position between the rotating sleeve and the connecting seat, making it more practical.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When the terminal passes through the plug hole and is plugged into the plug-in piece, the rotating sleeve between the plug seat and the connecting seat is rotated. The rotation of the rotating sleeve drives the tightening protrusion to rotate. The rotation of the tightening protrusion drives the two tightening blocks to slide toward the terminal until the two tightening blocks tighten and fix the terminal. The setting of the tightening blocks makes the connection between the plug board and the plug more stable, which improves the stability of the plug connection by only tightening the plug-in piece on both sides of the terminal. During use, the connection state between the plug board and the plug is prone to instability, which leads to poor contact.

[0029] 2. The setting of the rubber block makes the two clamping blocks more stable in clamping the terminals, making the practicability better.

[0030] 3. When the terminal is plugged into the plug-in piece, the pressing spring is pressed between the slider and the stopper, and the slider presses one end of the terminal through the elastic force of the pressing spring, making the plug-in fit between the terminal and the plug more stable.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] The present application embodiment discloses a plug. Figure 1 and Figure 2 A plug includes a rubber seat 1, a connecting seat 2 and a plug seat 3, the connecting seat 2 is fixedly connected to the rubber seat 1, the plug seat 3 is snap-fitted to the connecting seat 2, two card slots 31 are opened on the side of the plug seat 3 close to the connecting seat 2, and two card blocks 21 are fixedly arranged on the side of the connecting seat 2 close to the plug seat 3, the two card blocks 21 are respectively penetrated through the two card slots 31 and snap-fitted with the two card slots 31 respectively, thereby realizing the snap-fitting of the plug seat 3 and the connecting seat 2. In the embodiment of the present application, the side of the connecting seat 2 close to the rubber seat 1 is the bottom, the side close to the plug seat 3 is the top, the side of the plug seat 3 close to the connecting seat 2 is the bottom, and the side away from the connecting seat 2 is the top.

[0038] Reference Figure 2 and Figure 3, the connecting seat 2 is circular. Two insertion slots 22 penetrating through are formed at the top of the connecting seat 2. The length of the insertion slots 22 is arranged from the direction close to the plug socket 3 to the direction away from the plug socket 3. The two insertion slots 22 are evenly distributed along the radial direction of the connecting seat 2. Two insertion pieces 27 are fixedly arranged in the insertion slots 22. Two insertion holes penetrating through are formed at the bottom of the plug socket 3, which facilitates the terminals to pass through the plug socket 3 and be inserted and matched with the insertion pieces 27. Two abutting blocks 23 are slidably matched with the top of the connecting seat 2. The two abutting blocks 23 are both triangular. Through slots 233 penetrating through are respectively formed at the tops of the two abutting blocks 23. Two guiding rods 28 are fixedly arranged on the connecting seat 2. The two guiding rods 28 respectively penetrate through the two through slots 233 and are slidably matched with the two through slots 233.

[0039] Refer to Figure 2 and Figure 3 , the hypotenuses of the two abutting blocks 23 are arranged opposite to each other. The opposite hypotenuses of the two abutting blocks 23 are located at the tops of the two insertion slots 22. Two rubber blocks 231 are fixedly arranged on one side of the opposite hypotenuses of the two abutting blocks 23. The four rubber blocks 231 are paired to respectively abut and fix the two sides of the two terminals. The arrangement of the rubber blocks 231 makes the abutting of the two abutting blocks 23 on the terminals more stable. Two return springs 232 are arranged on one side of the opposite hypotenuses of the two abutting blocks 23. The two ends of each of the two return springs 232 are respectively fixedly connected to the two abutting blocks 23, so that when the two abutting blocks 23 approach, there is a tendency to move away from each other, so that the arrangement of the two abutting blocks 23 is not likely to interfere with the insertion of the terminals into the insertion pieces 27.

[0040] Refer to Figure 2 and Figure 3 , the plug socket 3 is circular. Two U-shaped stoppers 32 are fixedly arranged at the bottom of the plug socket 3. The two U-shaped stoppers 32 are evenly distributed along the radial direction of the plug socket 3. Two sliders 33 are slidably matched with the tops of the two abutting blocks 23. The sliders 33 are rectangular. Compression springs 34 are respectively arranged between the sliders 33 and the two stoppers 32. One ends of the two compression springs 34 are respectively fixedly connected to the stoppers 32, and the other ends of the two compression springs 34 are both fixedly connected to the sliders 33. An inclined surface 331 is arranged at the top of the slider 33. The inclined surface 331 is inclined downward from the end close to the compression spring 34 to the end away from the compression spring 34.

[0041] Refer to Figure 2 and Figure 3When the plug is plugged into the socket, the top of the terminal abuts against the inclined surface 331 of the slider 33, and a force is given to the inclined surface 331 toward the connecting seat 2. Through the guidance of the inclined surface 331, part of the force is converted into a force toward the clamping spring 34, and the slider 33 is pushed toward the stopper 32 until the slider 33 is pushed away from the top of the position where the two clamping blocks 23 are facing each other, and the terminal is smoothly inserted into the plug-in slot 22 through the slider 33. When the terminal is plugged into the plug-in sheet 27, the clamping spring 34 is pressed between the slider 33 and the block 32. The slider 33 clamps one end of the terminal through the elastic force of the clamping spring 34, making the plug-in cooperation between the terminal and the plug more stable. At the same time, when the plug is not in use, the slider 33 is located at the top of the position where the two clamping blocks 23 are facing each other to close the plug-in slot 22, making it difficult for dust to enter the plug-in slot 22, thereby affecting the use of the plug.

[0042] Reference Figure 2 and Figure 4 The bottom of the plug seat 3 is provided with a circular rotating sleeve 4, and the rotating block 41 is fixedly provided with the rotating sleeve 4 between the plug seat 3 and the connecting seat 2. When the rotating sleeve 4 and the plug seat 3 are rotated, the rotating block 41 is inserted into the rotating groove 35 and rotates in the rotating groove 35, so that the rotational cooperation between the rotating sleeve 4 and the plug seat 3 is more stable. The rotating sleeve 4 is fixedly provided with a tightening protrusion 42 inside the rotating sleeve 4, and the tightening protrusion 42 is elliptical. When the short axis of the tightening protrusion 42 is perpendicular to the hypotenuse of the two tightening blocks 23, the tightening protrusion 42 presses the two tightening blocks 23 tightly. When the long axis of the tightening protrusion 42 is perpendicular to the hypotenuse of the two tightening blocks 23, the tightening protrusion 42 is separated from the two tightening blocks 23. By rotating the rotating sleeve 4, the tightening protrusion 42 is driven to realize the tightening and unlocking of the two terminals of the two tightening blocks 23, so that the tightening and fixing of the plug and the socket are simple and quick.

[0043] Reference Figure 2 and Figure 4 A circular sealing groove 24 is provided at the bottom of the rotating sleeve 4, and a sealing ring 25 is snap-fitted in the sealing groove 24. The sealing ring 25 is made of rubber material. When the rotating sleeve 4 and the connecting seat 2 are rotated and matched, the sealing ring 25 abuts against the top of the connecting seat 2, so that the connection sealing between the rotating sleeve 4 and the connecting seat 2 is higher, and dust is not easy to enter the inside of the plug from the connection position between the rotating sleeve 4 and the connecting seat 2. A rubber sleeve 43 is fixedly provided on the outer peripheral surface of the rotating sleeve 4. The rubber sleeve 43 is made of rubber material, so that the usability of the rotating sleeve 4 is better. At the same time, the rotating sleeve 4 is rotated by the rubber sleeve 43 made of rubber material, so that when leakage occurs, the current is not easy to contact the human body through the rubber sleeve 43, so that the safety is better.

[0044] Reference Figure 2 and Figure 3A connecting groove 36 is provided at the top of the socket 3. The connecting groove 36 is circular. A plurality of guide blocks 361 are fixedly arranged on the wall of the connecting groove 36. The length of each guide block 361 is arranged from the top of the connecting groove 36 to the bottom of the connecting groove 36. When the plug is plugged into the socket, each guide block 361 passes through the plurality of guide grooves of the socket and slides with the plurality of guide grooves of the socket, thereby making it easier to guide the guide blocks 361 when the plug and the socket are plugged into each other. The setting of the connecting groove 36 makes the connection position between the socket and the plug change from the top of the socket 3 to the bottom of the connecting groove 36, so that the connection position between the socket and the plug is located inside the socket 3, so that the connection stability between the socket and the plug is better.

[0045] Reference Figure 2 and Figure 4 Two abutment grooves 37 are arranged through the bottom of the connecting groove 36, and the two abutment grooves 37 are distributed opposite to each other along the radial direction of the connecting groove 36. The connecting seat 2 is fixedly provided with an abutment piece 26, and the abutment piece 26 has elasticity. The two ends of the abutment piece 26 are respectively penetrated in the two abutment grooves 37, and the two ends of the abutment piece 26 are respectively bent in the directions opposite to each other at the two ends of the abutment piece 26, so that when the socket and the plug are plugged in, when the socket moves along the bending direction of the abutment piece 26, the two ends of the abutment piece 26 move away from each other, so that the abutment piece 26 is not easy to affect the socket to move toward the plug seat 3. When the socket and the plug are plugged in, the abutment piece 26 abuts against the two sides of the socket through its own elasticity, so that the plug-in cooperation between the socket and the plug is more stable.

[0046] Reference Figure 1 The rubber seat 1 is fixedly provided with a dustproof belt 11, one end of the dustproof belt 11 is fixedly connected with a dustproof cover 12, the dustproof belt 11 is elastic, and a dustproof seat 5 is fixedly provided on the top of the socket 3, and the dustproof cover 12 is snap-fitted with the dustproof seat 5. When the plug is not in use, the dustproof cover 12 is snap-fitted with the dustproof seat 5, so that the connecting groove 36 is airtight, so that dust is not easy to enter the plug. When the plug is used, the dustproof seat 5 is separated from the dustproof cover 12, the connecting groove 36 is opened, and the dustproof cover 12 separated from the dustproof seat 5 is fixed to the plug through the dustproof belt 11, making it easier and more convenient to use.

[0047] The implementation principle of a plug in the embodiment of the present application is as follows: when the plug is plugged into the socket, the dust cover 12 is separated from the dust seat 5, the connecting groove 36 is opened, the plug moves toward the socket, the socket slides along the depth direction of the connecting groove 36 and is guided by the guide block 361, the socket abuts against both ends of the abutment sheet 26, so that the two ends of the abutment sheet 26 move away from each other, the terminal of the socket passes through the plug-in hole and abuts against the inclined surface 331 of the slider 33, and the slider 33 is pushed open, the terminal passes through the opposite position of the two abutment blocks 23 and enters the plug-in groove 22, and is plugged into and matched with the plug-in sheet 27 of the plug-in groove 22, and at the same time, the top of the socket abuts against the bottom of the connecting groove 36, the two ends of the abutment sheet 26 respectively abut the two sides of the socket, and the slider 33 abuts against the terminal;

[0048] The rotating sleeve 4 is rotated by the rubber sleeve 43, and the rotating sleeve 4 drives the pressing protrusion 42 to rotate. The pressing protrusion 42 makes the two pressing blocks 23 slide towards each other, and the four rubber blocks 231 respectively press and fix the two sides of the two terminals, so that the connection between the plug and the socket is more stable, which improves the stability of the plug insertion by only pressing the two sides of the terminal by the plug-in piece 27. During use, the connection state between the plug board and the plug is easy to be unstable, which leads to the problem of poor contact.

[0049] When the plug and the socket need to be separated, the rotating sleeve 4 is rotated through the rubber sleeve 43, so that the two locking blocks move away from each other through the return spring 232, and the plug is pulled out, and the plug and the socket are separated, thereby making the operation of locking and separating the plug and the socket simple and quick, making it more practical.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
