Description

Technical Field

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

[0002] PIN pin is a metal material used in connectors to conduct electricity (signals). It is an important component of optical communication networks. PIN pin connector is a common connector that is widely used in power supply and communication connections between electronic devices. It is easy to assemble and disassemble and has high connection reliability, which brings a lot of convenience to the interconnection and expansion between devices.

[0003] In the prior art, the patent with publication number CN207910104U discloses a waterproof PIN pin connector. When the end of the PIN pin is inserted into the plug hole, the sealing ring is deformed by pressure and fits tightly against the locking portion, so that a good sealing effect can be produced, so that the connector has reliable waterproof performance. However, in this patent, when the plug is inserted into the connector, since there is no fixing measure, it is very easy for people to take off the plug when walking or touching the plug or the wire on the plug for other reasons. Therefore, the connector has the problem of not being able to firmly fix the plug. Therefore, a waterproof PIN pin connector is needed to meet people's needs. Summary of the invention

A circular groove is provided in an annular shape on the inner wall of the mounting groove, and a round block is rotatably installed in the circular groove. The bottom end of the pressure rod is fixedly installed on the round block. When the pressure rod rotates, the round block rotates in the circular groove, thereby limiting the pressure rod and allowing it to only rotate.

[0009] Preferably, a pin rod located above the fixing frame is fixedly sleeved on the pressure rod, and the pin rod is matched with the pin hole. When the pin rod is pulled into the fixing frame, the pressure rod can be made perpendicular to the pin hole by simply rotating the pressure rod, thereby clamping the pressure rod.

[0012] The beneficial effects of the present invention are:

[0013] In the present invention, by setting the pressure plate and the fixed plate, when the plug is inserted into the connector body, the two pressure plates are driven to move, and the two pressure plates drive the four rotating plates to rotate through two pull rods, so that the two fixed plates can clamp the plug, so that the plug can be firmly plugged into the connector, making the use of the connector more stable and meeting people's needs.

[0014] In the present invention, by setting the pin hole and the pin rod, when the two fixing plates clamp the plug, the pin rod can be brought into the fixing frame. At this time, the pin rod can be rotated by simply rotating the pressure rod, so that the pin rod is perpendicular to the pin hole, and then the pressure rod can be clamped, so that the positions of the two fixing plates can be fixed, which is convenient to use.

[0022] In the present invention, two through holes are opened on the pressing plate 3, and limiting rods 15 are movably installed in the two through holes. The bottom ends of the two limiting rods 15 are fixedly installed on the fixing frame 2. The pressing plate 3 slides vertically on the two limiting rods 15 through the two through holes, so that the pressing plate 3 can be limited.

[0023] In the present invention, a spring 16 is sleeved on the limiting rod 15, the top end of the spring 16 is fixedly mounted on the pressure plate 3, and the bottom end of the spring 16 is fixedly mounted on the fixing frame 2. Through the setting of the spring 16, when the contact pressure rod 12 is locked, the pressure plate 3 can be reset.

[0024] In the present invention, a mounting groove 11 is provided on the pressure plate 3, and the bottom end of the pressure rod 12 extends into the mounting groove 11. A circular groove 17 is provided in an annular shape on the inner wall of the mounting groove 11. A round block 18 is rotatably installed in the circular groove 17. The bottom end of the pressure rod 12 is fixedly installed on the round block 18. When the pressure rod 12 rotates, the round block 18 rotates in the circular groove 17, thereby limiting the pressure rod 12 so that it can only rotate.

[0025] In the present invention, a pin rod 14 located above the fixing frame 2 is fixedly sleeved on the pressure rod 12, and the pin rod 14 is adapted to the pin hole 13. When the pin rod 14 is pulled into the fixing frame 2, the pressure rod 12 only needs to be rotated to make the pin rod 14 perpendicular to the pin hole 13, so that the pressure rod 12 can be clamped.

[0026] In the present invention, a rotating shaft hole 7 is opened on the rotating plate 4, a rotating shaft 8 is rotatably installed in the rotating shaft hole 7, the rotating shaft 8 is fixedly installed on the fixing frame 2, and the rotating plate 4 rotates on the rotating shaft 8 through the rotating shaft hole 7.

The two pins 10 are respectively fixedly installed on the pressure plate 3 and the rotating plate 4. When the pull rod 6 moves, it rotates on the two pins 10 through the two pin holes 9.

[0028] How this utility works:

[0029] When it is necessary to insert the plug into the connector body 1, first move the plug so that the plug can move against the two pressure plates 3. The pressure plates 3 move vertically on the two limiting rods 15 through the two through holes, and the two springs 16 are forced to contract. At the same time, the pressure plate 3 moves through the two pin shafts 10 to pull the two pull rods 6 to move. The two pull rods 6 drive the two rotating plates 4 to rotate through the other two pin shafts 10. The two rotating plates 4 rotate on the two rotating shafts 8 through the rotating shaft holes 7. The rotation of the two rotating plates 4 drives the same fixed plate 5 to move, so that the plug can be inserted into the connector body 1. After that, the plug can be pressed by the fixing plate 5, and at the same time, the pressing plate 3 moves through the round block 18 to drive the pressing rod 12 to move, and the movement of the pressing rod 12 drives the pin 14 to move, so that the pin 14 moves into the fixing frame 2, and then the pressing rod 12 is rotated to make the pressing rod 12 rotate in the round groove 17 through the round block 18 until the pin 14 is perpendicular to the pin hole 13, so that the pin 14 can clamp the pressing rod 12, and then the position of the fixing plate 5 is fixed, so that the two fixing plates 5 can firmly clamp the plug on the connector body 1, thereby preventing the plug from detaching.
