Description

Technical Field

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

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

[0003] Existing pin connectors are commonly used in applications that require frequent disassembly and reconnection. For example, China's authorized patent for a connector with a quick-plug self-locking function and its processing technology (application number: CN202410361852.7) discloses a connector with a quick-plug self-locking function. By setting a hidden disk, after the foreman connector is separated from the wood connector, the pin can be retracted into the through hole in the hidden disk, thereby hiding the pin. In conjunction with the groove and the embedded block, the holes on the jack disk can be aligned one by one with the holes on the hidden disk, thereby realizing the plug-in connection between the foreman connector and the wood connector.

[0004] In the prior art, although the pins can be hidden by a hidden tray to prevent foreign objects from blocking the pins and thus protect the pins, when the connector is not in use, the socket is exposed. At this time, fine dust in the environment can easily enter the socket and adhere to the inner wall of the socket, thereby reducing the insulation performance of the connector, increasing the failure rate of the connector, and reducing the heat dissipation effect of the connector connection, which can easily cause the connector to overheat, thereby affecting the working stability and service life of the connector. Summary of the invention

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0020] like Figure 1-Figure 8 As shown, in the embodiment, a connector with a quick-insertion self-locking function is provided, 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 on one end of the first connecting cylinder 2, a female connector 4 is fixedly installed on one end of the second connecting cylinder 3, a socket 5 is fixedly installed on one end of the female connector 4 close to the second connecting cylinder 3, and a protective component is arranged on one side of the socket 5; The protection component includes an adjusting wheel 6 arranged on one side of the socket 5, and a first limiting groove 7 is evenly opened on one side of the adjusting wheel 6. A driving rod 8 is slidably installed on the inner side of the first limiting groove 7, and a protective plate 9 is fixedly installed on one end of the driving rod 8. The protective plate 9 is slidably installed on one side of the adjusting wheel 6. When the connector is not in use and the male connector 1 is separated from the female connector 4, the protective plates 9 fit together to form a barrier surface to prevent dust in the environment from falling on the inner wall of the socket 5. A driving component is arranged on the side of the adjusting wheel 6 away from the socket 5.

[0021] See also Figures 1 to 8As shown, the driving assembly includes a first driving cylinder 10 arranged on one side of the adjusting wheel 6, and first driving grooves 11 are symmetrically provided on both sides of the first driving cylinder 10. A second driving cylinder 12 is rotatably installed on the outer wall of the first driving cylinder 10, and the second driving cylinder 12 is fixedly installed on one side of the female connector 4. Second driving grooves 13 are symmetrically provided on both sides of the second driving cylinder 12, which can limit the moving trajectory of the driving block 14, so that the driving block 14 moves along the second driving groove 13, and 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, and a second locking assembly is provided on one side of the second driving groove 13, and the inner wall of the second driving groove 13 is slidably installed with the driving block 14, and the driving block 14 is fixed on the inner side of the first connecting cylinder 2, and a first locking assembly is provided on one side of the driving block 14.

[0022] In summary, by cooperating with the protection component and the driving component, when the driving block 14 moves toward 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, and then 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, so that the protection plates 9 are separated from each other, stop blocking the socket 5, and allow the pin to be plugged into the socket 5, and 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 through the first driving groove 11. The groove 11 drives the first driving cylinder 10 to rotate, and then the first driving cylinder 10 drives the protective plate 9 to move through the adjusting wheel 6, the first limiting groove 7 and the driving rod 8, so that the protective plates 9 fit together to form a barrier surface, which prevents dust in the environment from falling on the inner wall of the socket 5, and avoids the socket 5 being in an exposed state when the connector is not in use. At this time, fine dust in the environment can easily enter the socket 5 and adhere to the inner wall of the socket 5, thereby reducing the insulation performance of the connector, increasing the failure rate of the connector, and reducing the heat dissipation effect of the connector connection, which can easily cause the connector to overheat, thereby affecting the working stability and service life of the connector, and improving the working efficiency and service life of the connector.

[0023] Embodiment 2 See also Figures 2 to 5 As shown, compared with Example 1, as another embodiment of the present invention, the first locking assembly includes a locking rod 15 arranged on one side of the driving block 14, the locking rod 15 is slidably installed on one side of the driving block 14, and a torsion spring is arranged in the axis of rotation of the locking rod 15. The inner wall of the second connecting tube 3 is symmetrically provided with locking grooves 16, which can make the locking rod 15 abut against the inner wall of the locking groove 16, thereby locking the male connector 1, and the locking grooves 16 are all opened on one side of the second driving groove 13, and the inner wall of the locking groove 16 is slidably installed with an unlocking block 17.

[0024] See also Figure 4 As shown, limit blocks 18 are fixedly installed on both sides of the unlocking block 17, and the limit blocks 18 are slidably installed on the inner wall of the second limit groove 19. The second limit grooves 19 are opened on both sides of the locking groove 16, which can limit the position of the unlocking block 17 and avoid the problem that the unlocking block 17 moves to the inside of the second connecting tube 3 or falls off from one side of the second connecting tube 3, thereby improving the stability and reliability of the first locking assembly.

[0025] To summarize, by providing the first locking component, when the male connector 1 and the female connector 4 are connected, the locking rod 15 can rotate in 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 drive block 14, and then hindering the movement of the male connector 1, completing the locking of the position of the male connector 1, and avoiding the problem of the male connector 1 being easily loosened and falling off after being connected to the female connector 4. In addition, when it is necessary to separate the male connector 1 from 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 in the direction close to the drive block 14, thereby stopping the limiting effect of the locking rod 15 on the drive 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 easily connected and separated.

[0026] See also Figure 5 and Figure 6 As shown, the second locking assembly includes an abutment block 20 arranged on one side of the second driving groove 13, the abutment block 20 is symmetrically installed on both sides of the second driving groove 13, the abutment blocks 20 are all slidably installed on the inner wall of the first slide groove 21, the first slide groove 21 is all opened on the inner side of the second driving groove 13, the abutment block 20 and the first slide groove 21 are connected by a first spring 22, a second slide groove 23 is opened on one side of the abutment block 20, the inner wall of the second slide groove 23 is slidably installed with a clamping block 24, the clamping block 24 and the abutment block 20 are connected by a second spring 25, and the end of the clamping block 24 away from the abutment block 20 is slidably installed on the inner wall of the clamping groove 26, and the clamping groove 26 is all opened on one side of the first driving cylinder 10.

[0027] See also Figure 5 and Figure 6 As shown, one end of the abutment block 20 is arranged in an inclined shape, so that when the driving block 14 abuts against the abutment block 20, the thrust of the driving block 14 can be decomposed into a vertical force through the arranged inclined surface, and the distance between the top and the bottom of the first slide groove 21 is greater than the distance between the top and the bottom of the abutment block 20, so that the abutment block 20 can be completely moved into the first slide groove 21, thereby avoiding the problem that the abutment block 20 hinders the movement of the driving block 14.

[0028] See also Figure 5 and Figure 6 As shown, one end of the block 24 is set as an inclined portion, the side of the inclined portion close to the second driving groove 13 is set as a straight surface, and the side of the inclined portion away from the second driving groove 13 is set as an inclined surface. The shape of the slot 26 is the same as the shape of the inclined portion of the block 24. When the driving block 14 drives the abutting block 20 to move toward the direction close to the first sliding groove 21, the abutting block 20 drives the block 24 to move. At this time, the block 24 can move out of the slot 26 along the inclined surface of the slot 26.

[0029] See also Figure 5 and Figure 6 The distance between the two ends of the inclined portion of the slot 26 is greater than the distance between the two ends of the slot 26, so that the portion where the block 24 abuts against the inclined surface of the slot 26 is always an inclined surface, thereby avoiding the problem that when the straight portion of the block 24 abuts against the inclined surface of the slot 26, the block 24 is difficult to move out of the slot 26 along the inclined surface of the slot 26.

[0030] To summarize, by providing a second locking assembly, the position of the first drive cylinder 10 can be locked when the separator is not in use, thereby preventing the first drive cylinder 10 from being rotated and installed on the inner wall of the second drive cylinder 12. When the male connector 1 and the female connector 4 are not connected, the first drive cylinder 10 is prone to deflection, causing the first drive groove 11 to move away from one side of the second drive groove 13, thereby causing the drive block 14 to abut against the first drive cylinder 10, hindering the movement of the drive block 14 and causing motion interference problems, thereby improving the stability and reliability of the drive assembly. In addition, the locking of the position of the first drive cylinder 10 can be automatically stopped when the drive assembly is operating.

[0031] See also Figures 1 to 3 , Figure 5 , Figures 7 and 8 As shown, the first driving groove 11 is composed of two sections of straight grooves and one section of inclined groove. By setting the straight groove close to the side of the female connector 4, the abutment wear between the pin and the socket 5 and the adjusting wheel 6 can be avoided, thereby reducing the service life of the pin. By setting the straight portion away from the side of the female connector 4, it can make it easier and more labor-saving for the staff to push the male connector 1.

[0032] See also Figure 1 and Figure 2 As shown, the inner diameter of the first connecting tube 2 is equal to the outer diameter of the second connecting tube 3. Compared with the prior art, by sleeve-fitting the first connecting tube 2 onto the outer wall of the second connecting tube 3, the connection between the male connector 1 and the female connector 4 can be strengthened, and protection can be provided for the relatively fragile connection.

[0033] Working principle: When the connector is not in use and the male connector 1 is separated from the female connector 4, the protective plates 9 fit together to form a barrier surface to prevent dust in the environment from falling on the inner wall of the jack 5; When the connector is in use, the staff pushes the male connector 1 so that the first connecting tube 2 is sleeved with the second connecting tube 3, so that the second connecting tube 3 abuts against the locking rod 15 and drives the locking rod 15 to rotate in the direction close to the driving block 14, and the first connecting tube 2 continues to move in the direction close to the second connecting tube 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 into a vertical force through the inclined surface set, so that the abutting block 20 moves in the direction close to the first sliding groove 21, and the abutting block 20 squeezes the first spring 22, so that the first spring 22 undergoes elastic deformation and accumulates elastic potential energy. At the same time, the abutting block 20 reaches the movement of the card block 24, so that the card block 24 slides out of the card slot 26 along the inclined surface of the card slot 26, so that the second locking assembly stops restricting the first driving tube 10. At this time, the card block 24 squeezes the second sliding groove 23, so that the second sliding groove 23 undergoes elastic deformation and accumulates elastic potential energy. The staff continues to push the male connector 1 The first connector 1 drives the driving block 14 to move along the second driving groove 13, and at the same time, the driving block 14 drives the first driving groove 11 to rotate, and the first driving groove 11 drives the first driving cylinder 10 to rotate, and the first driving cylinder 10 drives the adjusting wheel 6 to rotate, and 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 protective plate 9 to move, so that the protective plates 9 are separated from each other, and the blocking protection of the socket 5 is stopped, and 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 set in the first connecting cylinder 2 is plugged into the socket 5, thereby completing the connection of the connector, and 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, and the male connector 1 is fixed; When it is necessary to separate the male connector 1 and the female connector 4, the staff presses the unlocking block 17 so that the unlocking block 17 pushes the locking rod 15 to move in the direction close to the driving block 14, and then the staff pulls the male connector 1 so that the male connector 1 drives 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, so that 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. The protection plates 9 are made to fit together to form a barrier surface, preventing dust in the environment from falling on the inner wall of the socket 5. When the driving block 14 moves to one side of the abutment block 20, the driving block 14 stops abutting against the abutment block 20. At this time, the first spring 22 releases its elastic potential energy and elastically deforms to push the abutment block 20 to move away from the first slide groove 21. When the abutment block 20 moves to one side of the card slot 26, the second spring 25 releases its elastic potential energy and elastically deforms to push the card block 24 to move to the inner wall of the card slot 26, thereby fixing the first driving cylinder 10.
