Description

Technical Field

[0001] The present invention relates to the field of connectors, and more specifically, to a connector with a quick-insert self-locking function. Background Art

[0002] A pin connector is an electrical connector mainly used to connect two electronic devices or circuit boards in a circuit. It usually consists of a female socket and a male head. The male head has multiple metal pins, and the female socket has corresponding slots. When the pins are inserted into the slots, they can contact the contact points to complete the circuit connection. The pin connector has the characteristics of easy use, quick connection, and reliability.

[0003] Existing pin connectors are commonly used and widely applied in applications that require frequent disassembly and reconnection. For example, a Chinese authorized patent, a connector with a quick-insert self-locking function and its processing technology (application number: CN202410361852.7), discloses a connector with a quick-insert self-locking function. By setting a hidden disk, after the head connector is separated from the wood connector, the pins can be retracted into the through holes in the hidden disk, thereby realizing the hiding of the pins. And with the cooperation of the groove and the embedded block, the holes on the jack disk can be aligned with the holes on the hidden disk one by one, thus realizing the insertion of the head connector and the wood connector.

[0004] In the prior art, although the pins can be stored and hidden by the hidden disk to avoid foreign objects from jamming the pins and thus protect the pins, when the connector is not in use, the jacks are in an exposed state. At this time, fine dust in the environment easily enters the jacks and adheres to the inner walls of the jacks, thereby reducing the insulation performance of the connector, increasing the failure rate of the connector, and also reducing the heat dissipation effect at the connection of the connector, easily causing the connector to overheat, and further affecting the working stability and service life of the connector. Summary of the Invention

[0005] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a connector with a quick-insert self-locking function, which can overcome the problem that when the connector is not in use, the jacks are in an exposed state, and at this time, fine dust in the environment easily enters the jacks and adheres to the inner walls of the jacks, thereby reducing the insulation performance of the connector, increasing the failure rate of the connector, and also reducing the heat dissipation effect at the connection of the connector, easily causing the connector to overheat, and further affecting the working stability and service life of the connector.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] The present invention provides a connector with a quick-insert self-locking function, including a male connector; on one side of the male connector, a first connecting cylinder is fixedly installed, an insertion pin is arranged inside the first connecting cylinder, one end of the first connecting cylinder is sleeved with a second connecting cylinder, a female connector is fixedly installed at one end of the second connecting cylinder, a jack is fixedly installed at one end of the female connector close to the second connecting cylinder, and a protection component is arranged on one side of the jack;

[0008] The protection component includes an adjusting wheel arranged on one side of the jack. A first limiting groove is evenly opened on one side of the adjusting wheel. Driving rods are slidably installed inside the first limiting grooves. Protection plates are fixedly installed at one ends of the driving rods. The protection plates are slidably installed on one side of the adjusting wheel. A driving component is arranged on the side of the adjusting wheel away from the jack; when the connector is not in use and the male connector and the female connector are separated, the protection plates are mutually attached to form a barrier surface to prevent dust in the environment from falling on the inner wall of the jack.

[0009] In a preferred technical solution of the present invention, the driving component includes a first driving cylinder arranged on one side of the adjusting wheel. First driving grooves are symmetrically opened on both sides of the first driving cylinder. A second driving cylinder is rotatably installed on the outer wall of the first driving cylinder. The second driving cylinder is fixedly installed on one side of the female connector. Second driving grooves are symmetrically opened on both sides of the second driving cylinder. A second locking component is arranged on one side of the second driving groove. Driving blocks are slidably installed on the inner walls of the second driving grooves. The driving blocks are all fixed inside the first connecting cylinder. A first locking component is arranged on one side of the driving blocks; when the staff connects the male connector and the female connector, the protection component can be automatically opened, and when the staff separates the male connector and the female connector, the protection component can be automatically closed.

[0010] In a preferred technical solution of the present invention, the first locking component includes locking rods arranged on one side of the driving blocks. The locking rods are all slidably installed on one side of the driving blocks. Torsion springs are arranged inside the rotation axes of the locking rods. Locking grooves are symmetrically opened on the inner wall of the second connecting cylinder. The locking grooves are all opened on one side of the second driving groove. Unlocking blocks are slidably installed on the inner walls of the locking grooves; when the male connector and the female connector are completely connected, the locking rods rotate towards the direction close to the locking grooves under the elastic action of the torsion springs, so that the locking rods abut against the inner walls of the locking grooves, hindering the movement of the driving blocks, and further hindering the movement of the male connector to complete the locking of the position of the male connector.

[0011] In a preferred technical solution of the present invention, limiting blocks are fixedly installed on both sides of the unlocking block, and the limiting blocks are all slidably installed on the inner wall of the second limiting groove, and the second limiting grooves are all opened on both sides of the locking groove; the position of the unlocking block can be limited, avoiding the problem that the unlocking block moves into the second connecting cylinder or falls off from one side of the second connecting cylinder, and improving the stability and reliability of the first locking assembly.

[0012] In a preferred technical solution of the present invention, the second locking assembly includes abutting blocks arranged on one side of the second driving groove, the abutting blocks are symmetrically installed on both sides of the second driving groove, the abutting blocks are all slidably installed on the inner wall of the first sliding groove, the first sliding grooves are all opened inside the second driving groove, the abutting blocks and the first sliding grooves are all connected by a first spring, a second sliding groove is opened on one side of each abutting block, a clamping block is slidably installed on the inner wall of each second sliding groove, the clamping blocks and the abutting blocks are all connected by a second spring, and the ends of the clamping blocks far from the abutting blocks are all slidably installed on the inner wall of the clamping groove, and the clamping grooves are all opened on one side of the first driving cylinder; when the separator is not in use, the position of the first driving cylinder can be locked.

[0013] In a preferred technical solution of the present invention, one end of the abutting block is set to be inclined, and the distance from the top end to the bottom end of the first sliding groove is greater than the distance from the top end to the bottom end of the abutting block; when the driving block abuts against the abutting block, a vertical force can be decomposed from the thrust of the driving block through the arranged inclined surface.

[0014] In a preferred technical solution of the present invention, one end of the clamping block is set to be an inclined part, the side of the inclined part close to the second driving groove is set to be a flat straight surface, the side of the inclined part far from the second driving groove is set to be an inclined surface, and the shape of the clamping groove is the same as the shape of the inclined part of the clamping block; when the driving block drives the abutting block to move towards the direction close to the first sliding groove, the abutting block can drive the clamping block to move, and at this time, the clamping block can move out of the clamping groove along the inclined surface of the clamping groove.

[0015] In a preferred technical solution of the present invention, the distance between the two ends of the inclined part of the clamping groove is greater than the distance between the two ends of the clamping groove; it can ensure that the part where the clamping block abuts against the inclined surface of the clamping groove is always an inclined surface, avoiding the problem that when the flat part of the clamping block abuts against the inclined surface of the clamping groove, it is difficult for the clamping block to move out of the clamping groove along the inclined surface of the clamping groove.

[0016] In a preferred technical solution of the present invention, the first driving groove is composed of two straight grooves and one inclined groove; it can avoid the problem of the contact wear between the insertion pin and the insertion hole and the adjusting wheel, thereby reducing the service life of the insertion pin. By setting the straight part far from the female head connector, it can make it easier and more labor-saving for the staff to push the male head connector.

[0017] In a preferred technical solution of the present invention, the inner diameter of the first connecting cylinder is equal to the outer diameter of the second connecting cylinder; this can enhance the connection between the male connector and the female connector and provide a protective effect on the relatively fragile connection part.

[0018] The beneficial effects of the present invention are as follows:

[0019] A connector with a quick-insert self-locking function provided by the present invention, through the cooperation of a protection component and a driving component, when the driving block moves in the direction close to the female connector, the driving block can move along the second driving groove, so that the driving block drives the first driving cylinder to rotate through the first driving groove, and then the first driving cylinder drives the protection plate to move through the adjusting wheel, the first limiting groove and the driving rod, so that the protection plates are separated from each other, stop blocking the jacks, and enable the pins to be inserted into the jacks. When the driving block moves in the direction away from the female connector, the driving block can move along the second driving groove, so that the driving block drives the first driving cylinder to rotate through the first driving groove, and then the first driving cylinder drives the protection plate to move through the adjusting wheel, the first limiting groove and the driving rod, so that the protection plates are attached to each other to form a barrier surface, preventing dust in the environment from falling on the inner wall of the jacks. This avoids the problem that when the connector is not in use, the jacks are in an exposed state, and at this time, fine dust in the environment easily enters the jacks and adheres to the inner wall of the jacks, thereby reducing the insulation performance of the connector, increasing the failure rate of the connector, and also reducing the heat dissipation effect at the connection part of the connector, easily causing the connector to overheat, and further affecting the working stability and service life of the connector. It improves the working efficiency and service life of the connector;

[0020] By setting the first locking component, when the male connector and the female connector are connected, the locking rod rotates in the direction close to the locking groove under the elastic action of the torsion spring, so that the locking rod abuts against the inner wall of the locking groove, hindering the movement of the driving block, and further hindering the movement of the male connector, completing the locking of the position of the male connector, avoiding the problem that the male connector and the female connector are easy to loosen and fall off after connection. In addition, when it is necessary to separate the male connector and the female connector, the staff can press the unlocking block, so that the unlocking block pushes the locking rod to rotate in the direction close to the driving block, thus stopping the limiting effect of the locking rod on the driving block. At this time, the male connector and the female connector can be easily separated, so that the male connector and the female connector can be quickly and simply connected and separated.

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0032] As Figures 1-8 shown, an embodiment provides a connector with a quick-insert self-locking function, including a male connector 1; a first connecting cylinder 2 is fixedly installed on one side of the male connector 1, a pin is arranged inside the first connecting cylinder 2, a second connecting cylinder 3 is sleeved at one end of the first connecting cylinder 2, a female connector 4 is fixedly installed at one end of the second connecting cylinder 3, a jack 5 is fixedly installed at one end of the female connector 4 close to the second connecting cylinder 3, and a protection component is arranged on one side of the jack 5;

[0033] The protection component includes an adjusting wheel 6 arranged on one side of the jack 5. A first limiting groove 7 is evenly formed on one side of the adjusting wheel 6. Driving rods 8 are slidably installed inside the first limiting grooves 7. One ends of the driving rods 8 are fixedly installed with protection plates 9. The protection plates 9 are slidably installed on one side of the adjusting wheel 6. When the male connector 1 and the female connector 4 are separated without using the connector, the protection plates 9 are mutually attached to form a blocking surface, preventing dust in the environment from falling on the inner wall of the jack 5. A driving component is arranged on the side of the adjusting wheel 6 away from the jack 5.

[0034] Please refer to Figures 1 to 8 As shown, the driving component includes a first driving cylinder 10 arranged on one side of the adjusting wheel 6. First driving grooves 11 are symmetrically formed on both sides of the first driving cylinder 10. The outer wall of the first driving cylinder 10 is rotatably installed with a second driving cylinder 12. The second driving cylinder 12 is fixedly installed on one side of the female connector 4. Second driving grooves 13 are symmetrically formed on both sides of the second driving cylinder 12, which can limit the movement track of the driving block 14, enabling the driving block 14 to move along the second driving groove 13. At the same time, the driving block 14 moves in the first driving groove 11, so that the driving block 14 can drive the first driving cylinder 10 to rotate through the first driving groove 11. A second locking component is arranged on one side of the second driving groove 13. Driving blocks 14 are slidably installed on the inner walls of the second driving grooves 13. The driving blocks 14 are all fixed inside the first connecting cylinder 2. A first locking component is arranged on one side of the driving block 14.

[0035] In summary, through the cooperation of the protection component and the driving component, when the driving block 14 moves in the direction close to the female connector 4, the driving block 14 can move along the second driving groove 13, so that the driving block 14 drives the first driving cylinder 10 to rotate through the first driving groove 11. Further, the first driving cylinder 10 drives the protection plate 9 to move through the adjusting wheel 6, the first limiting groove 7 and the driving rod 8, separating the protection plates 9 from each other, stopping the shielding of the jack 5, enabling the pin to be inserted into the jack 5. When the driving block 14 moves in the direction away from the female connector 4, the driving block 14 can move along the second driving groove 13, so that the driving block 14 drives the first driving cylinder 10 to rotate through the first driving groove 11. Further, the first driving cylinder 10 drives the protection plate 9 to move through the adjusting wheel 6, the first limiting groove 7 and the driving rod 8, making the protection plates 9 mutually attached to form a blocking surface, preventing dust in the environment from falling on the inner wall of the jack 5, avoiding the problem that when the connector is not in use, the jack 5 is in an exposed state, at this time, fine dust in the environment easily enters the jack 5 and adheres to the inner wall of the jack 5, thereby reducing the insulation performance of the connector, increasing the failure rate of the connector, and also reducing the heat dissipation effect at the connection of the connector, easily causing the connector to overheat, further affecting the working stability and service life of the connector, and improving the working efficiency and service life of the connector.

[0036] Embodiment 2

[0037] Please refer to Figures 2 to 5 As shown, compared with Embodiment 1, as another implementation manner of the present invention, the first locking assembly includes a locking rod 15 disposed on one side of the driving block 14. The locking rods 15 are all slidably mounted on one side of the driving block 14, and torsion springs are disposed inside the rotation axes of the locking rods 15. Locking grooves 16 are symmetrically formed on the inner wall of the second connecting cylinder 3, enabling the locking rods 15 to abut against the inner wall of the locking grooves 16, thereby locking the male connector 1. The locking grooves 16 are all formed on one side of the second driving groove 13, and unlocking blocks 17 are slidably mounted on the inner walls of the locking grooves 16.

[0038] Please refer to Figure 4 As shown, limiting blocks 18 are fixedly mounted on both sides of the unlocking block 17. The limiting blocks 18 are all slidably mounted on the inner walls of the second limiting grooves 19. The second limiting grooves 19 are all formed on both sides of the locking grooves 16, capable of limiting the position of the unlocking block 17, avoiding the problem that the unlocking block 17 moves into the second connecting cylinder 3 or falls off from one side of the second connecting cylinder 3, and improving the stability and reliability of the first locking assembly.

[0039] In summary, by providing the first locking assembly, when the male connector 1 and the female connector 4 are connected, the locking rod 15 rotates towards the direction close to the locking groove 16 under the elastic action of the torsion spring, so that the locking rod 15 abuts against the inner wall of the locking groove 16, hindering the movement of the driving block 14, and further hindering the movement of the male connector 1, thereby completing the locking of the position of the male connector 1 and avoiding the problem that the male connector 1 and the female connector 4 are easily loosened and detached after being connected. In addition, when it is necessary to separate the male connector 1 and the female connector 4, the staff can press the unlocking block 17, so that the unlocking block 17 pushes the locking rod 15 to rotate towards the direction close to the driving block 14, thereby stopping the limiting effect of the locking rod 15 on the driving block 14. At this time, the male connector 1 and the female connector 4 can be easily separated, so that the male connector 1 and the female connector 4 can be quickly and simply connected and separated.

[0040] Please refer to Figure 5 and Figure 6As shown, the second locking component includes abutting blocks 20 arranged on one side of the second driving groove 13. The abutting blocks 20 are symmetrically installed on both sides of the second driving groove 13. The abutting blocks 20 are all slidably installed on the inner wall of the first sliding groove 21. The first sliding grooves 21 are all opened inside the second driving groove 13. The abutting blocks 20 and the first sliding grooves 21 are all connected by first springs 22. A second sliding groove 23 is opened on one side of each abutting block 20. A clamping block 24 is slidably installed on the inner wall of the second sliding groove 23. The clamping block 24 and the abutting block 20 are all connected by a second spring 25. One end of the clamping block 24 away from the abutting block 20 is slidably installed on the inner wall of the clamping groove 26. The clamping grooves 26 are all opened on one side of the first driving cylinder 10.

[0041] Please refer to Figure 5 and Figure 6 As shown, one end of the abutting block 20 is set to be inclined. When the driving block 14 abuts against the abutting block 20, a vertical force can be decomposed from the thrust of the driving block 14 through the set inclined surface. The distance between the top and bottom of the first sliding groove 21 is greater than the distance between the top and bottom of the abutting block 20, which can enable the abutting block 20 to completely move into the first sliding groove 21 and avoid the problem that the abutting block 20 hinders the movement of the driving block 14.

[0042] Please refer to Figure 5 and Figure 6 As shown, one end of the clamping block 24 is set to be an inclined part. The side of the inclined part close to the second driving groove 13 is set to be a flat straight surface, and the side of the inclined part away from the second driving groove 13 is set to be an inclined surface. The shape of the clamping groove 26 is the same as the shape of the inclined part of the clamping block 24. When the driving block 14 drives the abutting block 20 to move towards the first sliding groove 21, the abutting block 20 can drive the clamping block 24 to move. At this time, the clamping block 24 can move out of the clamping groove 26 along the inclined surface of the clamping groove 26.

[0043] Please refer to Figure 5 and Figure 6 As shown, the distance between the two ends of the inclined part of the clamping groove 26 is greater than the distance between the two ends of the clamping groove 26, which can enable the part where the clamping block 24 abuts against the inclined surface of the clamping groove 26 to always be an inclined surface, avoiding the problem that it is difficult for the clamping block 24 to move out of the clamping groove 26 along the inclined surface of the clamping groove 26 when the flat part of the clamping block 24 abuts against the inclined surface of the clamping groove 26.

[0044] In summary, by setting the second locking component, the position of the first driving cylinder 10 can be locked when the separator is not in use, avoiding the problem that the first driving cylinder 10 is rotatably installed on the inner wall of the second driving cylinder 12. When the male connector 1 and the female connector 4 are not connected, the first driving cylinder 10 is prone to deflection, causing the first driving groove 11 to move away from one side of the second driving groove 13, so that the driving block 14 abuts against the first driving cylinder 10, hindering the movement of the driving block 14 and causing movement interference problems. This improves the stability and reliability of the driving component. In addition, the locking of the position of the first driving cylinder 10 can be automatically stopped when the driving component is operating.

[0045] Please refer to Figures 1 to 3 、 Figure 5 、 Figures 7 to 8 As shown, the first driving groove 11 is composed of two straight grooves and one inclined groove. By setting the straight groove close to the female connector 4, the problem of the contact wear between the pin and the jack 5 and the adjusting wheel 6 can be avoided, thereby reducing the problem of the short service life of the pin. By setting the straight part away from the female connector 4, it can make it easier and more labor-saving for the staff to push the male connector 1.

[0046] Please refer to Figure 1 and Figure 2 As shown, the inner diameter of the first connecting cylinder 2 is equal to the outer diameter of the second connecting cylinder 3. Compared with the prior art, by sleeving the first connecting cylinder 2 on the outer wall of the second connecting cylinder 3, the connection between the male connector 1 and the female connector 4 can be enhanced, and protection can be provided for the relatively fragile connection part.

[0047] Working principle: When the connector is not in use and the male connector 1 and the female connector 4 are separated, the protection plates 9 are mutually attached to form a barrier surface, hindering dust in the environment from falling on the inner wall of the jack 5;

[0048] When using the connector, the staff member pushes the male connector 1, so that the first connecting cylinder 2 is sleeved with the second connecting cylinder 3, causing the second connecting cylinder 3 to abut against the locking rod 15 and drive the locking rod 15 to rotate in the direction close to the driving block 14. The first connecting cylinder 2 continues to move in the direction close to the second connecting cylinder 3, so that one end of the driving block 14 abuts against the abutting block 20. At this time, the abutting block 20 decomposes the horizontal thrust of the driving block 14 through the set inclined surface to generate a vertical force, thereby causing the abutting block 20 to move in the direction close to the first chute 21. The abutting block 20 squeezes the first spring 22, causing the first spring 22 to undergo elastic deformation and accumulate elastic potential energy. At the same time, the abutting block 20 moves to the position of the locking block 24, causing the locking block 24 to slide out of the card slot 26 along the inclined surface of the card slot 26, so that the second locking component stops restricting the first driving cylinder 10. At this time, the locking block 24 squeezes the second chute 23, causing the second chute 23 to undergo elastic deformation and accumulate elastic potential energy. The staff member continues to push the male connector 1, so that the driving block 14 moves along the second driving groove 13. At the same time, the driving block 14 drives the first driving groove 11 to rotate, the first driving groove 11 drives the first driving cylinder 10 to rotate, the first driving cylinder 10 drives the adjusting wheel 6 to rotate, the adjusting wheel 6 drives the first limiting groove 7 to rotate, so that the first limiting groove 7 drives the driving rod 8 to move along the first limiting groove 7, and the driving rod 8 drives the protection plate 9 to move, causing the protection plates 9 to separate from each other and stop blocking and protecting the jack 5. The male connector 1 drives the driving block 14 to move to one end of the first driving groove 11 through the first connecting cylinder 2, so that the pin arranged in the first connecting cylinder 2 is inserted into the jack 5, thus completing the connection of the connector. At the same time, the driving block 14 drives the locking rod 15 to move to one side of the locking groove 16. At this time, the locking rod 15 rotates into the locking groove 16 under the elastic action of the torsion spring and pushes the unlocking block 17 to move, so that the locking rod 15 abuts against the inner wall of the locking groove 16 to fix the male connector 1;

[0049] When it is necessary to separate the male connector 1 from the female connector 4, the staff presses the unlocking block 17, causing the unlocking block 17 to push the locking rod 15 to move towards the driving block 14. Then, the staff pulls the male connector 1, causing the male connector 1 to drive the driving block 14 to move through the first connecting cylinder 2. At this time, the driving block 14 moves along the second driving groove 13, so that the driving block 14 drives the first driving groove 11 to rotate. The first driving groove 11 drives the protection plate 9 to move through the first driving cylinder 10, the adjusting wheel 6, the first limiting groove 7 and the driving rod 8, so that the protection plates 9 fit together to form a barrier surface, preventing dust in the environment from falling on the inner wall of the jack 5. When the driving block 14 moves to one side of the abutting block 20, the driving block 14 stops abutting against the abutting block 20. At this time, the first spring 22 releases its elastic potential energy and undergoes elastic deformation to push the abutting block 20 to move away from the first sliding groove 21. When the abutting block 20 moves to one side of the card slot 26, the second spring 25 releases its elastic potential energy and undergoes elastic deformation to push the locking block 24 to move to the inner wall of the card slot 26, thereby fixing the first driving cylinder 10.
