Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to a waterproof PIN connector. Background Art

[0002] PIN connectors are key connection components in electronic devices. They transmit electrical signals and power by plugging and unplugging metal pins into corresponding interfaces. They are widely used in consumer electronics, automobiles, industrial control and other fields. Their reliable connection performance ensures stable operation of the equipment.

[0003] Currently, in order to prevent water vapor intrusion from affecting the normal operation of PIN pin connectors, it is necessary to add a waterproof structure at the connection between the male and female connectors to improve their water vapor resistance. For example, patent publication number CN113078493A discloses a waterproof and anti-bending high-performance PIN pin connector. To improve the waterproof performance of existing waterproof PIN pin connectors, methods such as increasing the compression of the sealing ring and reducing the tolerance fit gap are often used to increase the plugging and unplugging tightness, resulting in a significant increase in the plugging and unplugging force. When the male and female connectors are axially offset or angularly skewed during the plugging and unplugging process, the metal pins with smaller diameters (usually ≤1mm) are susceptible to plastic bending deformation due to the lateral eccentric torque due to insufficient rigidity. At the same time, the sliding friction between the pin end face and the inner wall of the socket will be aggravated, resulting in wear of the surface plating and increased deviation of the pin cylindricity. This not only affects the conductive reliability, but also deteriorates the waterproof structure due to the increased sealing interface gap. The above problems are particularly prominent in high-frequency plugging and unplugging scenarios. Summary of the Invention

[0019] 2. The air storage unit can generate airflow when walking. After the male and female connectors are connected, the stored airflow can be used to further increase the sealing of the joint between the male and female connectors, achieving a good waterproof effect.

[0020] 3. By setting up the anti-drop component, the airflow stored in the air storage unit can be used to clamp and fix the male and female heads after they are plugged in, so as to avoid the male and female heads from loosening and improve the connection stability of the PIN connector.

[0034] The gear 81 is equipped with a transmission assembly 13, which is used to drive the gas storage piston 102 to move. The two transmission assemblies 13 include cams 131 arranged on both sides of the gear 81. The two cams 131 are fixedly arranged on the axle of the gear 81. Two extrusion rods 132 are fixedly installed on the side wall of the gas storage piston 102, and the two extrusion rods 132 are slidingly connected to the end of the cylinder 101. The rod ends of the two extrusion rods 132 are commonly fixedly connected to a connecting plate 133, and the side wall of the connecting plate 133 is fixedly connected to two impact rods 134. The two impact rods 134 extend to one side of the cam 131 away from the gas storage piston 102, and the rod end of the impact rod 134 is provided with a hemispherical structure to avoid a smooth transition between the impact rod 134 and the cam 131.

[0035] The groove wall of the annular mounting groove 91 is provided with a vent hole 14, and the side wall of the male head body 1 is provided with a vent groove 15 connected to the vent hole 14. The side wall of the male head body 1 is installed with a block 16 corresponding to the position of the vent groove 15, and the side wall of the block 16 is provided with a circular hole 17. The interior of the vent groove 15 is provided with a pressing block 18 that abuts against the side wall of the block 16. The pressing block 18 is used to seal the circular hole 17. A rubber support block 19 is fixedly provided between the side wall of the pressing block 18 and the groove wall of the vent groove 15. The circular hole 17 can be stably sealed by the support of the rubber support block 19 on the pressing block 18.

[0036] The operating principle of the present invention is now described as follows: when the male main body 1 and the female main body 2 are plugged in, the male main body 1 is aligned with the female main body 2, and then the plug-in cone sleeve 5 is inserted into the receiving cone sleeve 6. When the gear 81 on the side wall of the plug-in cone sleeve 5 contacts the meshing teeth 82 of the socket portion 4, the gear 81 can move along the meshing teeth 82, and due to the meshing action of the gear 81 and the meshing teeth 82, even if the direction of the force applied by the person is skewed or offset, the plug-in cone sleeve 5 cannot be skewed, so it can be Ensure that after the plug-in cone sleeve 5 is inserted into the receiving cone sleeve 6, the plug-in cone sleeve 5 and the receiving cone sleeve 6 remain in the same straight line. Similarly, when the male head body 1 is pulled out from the female head body 2, under the action of the gear 81 and the meshing teeth 82, the plug-in cone sleeve 5 and the receiving cone sleeve 6 can still be kept in the same straight line, thereby minimizing the bending of the metal pin portion 3 during the plugging and unplugging process of the male head body 1 and the female head body 2, and avoiding excessive wear of the male head body 1 and the female head body 2;

[0037] Among them, in the process of inserting the male head body 1, since the gear 81 is affected by the meshing teeth 82, the gear 81 will not only move along the meshing teeth 82, but also rotate. When rotating, the gear 81 will drive the two cams 131 to rotate through its own shaft. When the cam 131 is away from one end of the gear 81 axle and contacts the impact rod 134, the cam 131 will push the impact rod 134 to move, and the impact rod 134 will drive the extrusion rod 132 to move through the connecting plate 133, and the extrusion rod 132 will drive the gas storage piston 102 to move. The gas storage piston 102 will squeeze the space inside the cylinder 101. Under the action of the intake check valve 107 and the exhaust check valve 105, the air inside the cylinder 101 can only be discharged into the annular mounting groove 91 along the exhaust pipe 104. When the cam 131 is separated from the impact rod 134, under the action of the return spring 103, the gas storage piston 102 moves back and resets. At this time, the external air is replenished into the cylinder 101 through the air inlet hole 106. Through the rotation of the cam 131, the air storage piston 102 moves back and forth, and can continuously inflate the annular mounting groove 91. In the plugging process, the sealing block 122 blocks the plugging hole 121 under the action of the elastic pad 124. Therefore, the air in the annular mounting groove 91 cannot be discharged. Therefore, the air pressure in the annular mounting groove 91 continues to increase. Therefore, as the plugging goes deeper, due to the increase in the air pressure in the annular mounting groove 91, the air storage piston 102 compresses the pressure in the internal space of the cylinder 101, so the movement resistance of the air storage piston 102 becomes larger, thereby making the rotation resistance of the gear 81 larger. That is, as the plugging depth of the male head body 1 increases, the movement resistance of the male head body 1 becomes larger, thereby avoiding excessive plugging force applied by personnel, causing excessive collision between the metal pin part 3 and the socket part 4;

[0038] When the male connector body 1 is plugged into place, the plug rod 125 will be inserted into the plug hole 121, and the plug rod 125 will push the sealing block 122 to a certain distance. At this time, the air stored in the annular mounting groove 91 will enter the annular sealing groove 93 through the plug hole 121 and the diverter hole 126, thereby increasing the air pressure difference inside the sealing membrane ring 94. Under the action of positive pressure, the contact pressure between the sealing membrane ring 94 and the inner wall of the receiving cone sleeve 6 is increased, thereby improving the sealing performance of the plug cone sleeve 5 and the receiving cone sleeve 6 after plugging.

[0039] At the same time, part of the air that enters the annular sealing groove 93 will enter the interior of the groove 111, and the air pressure inside the groove 111 increases, which will push the anti-slip piston 113 outward, thereby pushing the anti-slip block 115 to be stuck in the anti-slip groove 116, thereby preventing the male connector body 1 and the female connector body 2 from being separated due to external force after being plugged in;

[0040] When the male body 1 and the female body 2 are to be separated, the operator presses the pressing block 18 to create a gap between the pressing block 18 and the stop block 16. At this time, the excess air in the annular sealing groove 93 and the groove 111 flows back to the vent hole 14 through the annular diversion hole 126, the plug hole 121, and the annular mounting groove 91, and is discharged through the vent groove 15. At this time, the anti-slip block 115 moves back and resets under the pulling action of the support spring 114, and the operator can pull out the male body 1.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
