Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a waterproof and sealed connector. Background Art

[0002] A connector is an electrical connector, which is mainly used to transmit current or signals. It has the advantage of easy plugging and unplugging. In order to ensure the stability of transmission after the connector is plugged in, the connector connection needs to be sealed and waterproofed to ensure the sealing after connection. For example, a sealed waterproof connector with announcement number CN214227222U includes a structural body, which will squeeze the sealed waterproof rubber ring when connected to the male connector joint, thereby achieving a waterproof effect. The left and right ends of the iron shell are provided with fixing holes, and a rubber core is fixed inside the iron shell. Several current terminals and signal terminals with two ends connected are interspersed inside the rubber core. The front end of the current terminal is provided with a first socket, and the front end of the signal terminal is provided with a second socket. The sealed waterproof rubber ring is interference-connected with the groove. However, the sealed waterproof connector still has the following disadvantages during actual use:

[0003] Although the above connector has a certain degree of waterproof sealing, it only relies on rubber to achieve the sealing of the connection, and the sealing effect is poor. Since the sizes of gaps after connection of different connectors are different, the rubber with a fixed structure cannot guarantee the sealing of the connection, and gaps still exist at the connection. In view of the above problems, it is urgently necessary to carry out innovative design based on the original connector. Utility Model Content

[0004] The purpose of the utility model is to provide a waterproof sealed connector to solve the problem that the above-mentioned background technology only relies on rubber to achieve the sealing of the connection, and the sealing effect is poor. Since the sizes of gaps after connection of different connectors are different, the use of rubber with a fixed structure cannot ensure the sealing of the connection, and the problem of gaps still existing at the connection.

[0005] To achieve the above object, the utility model provides the following technical solution: a waterproof sealed connector, provided with a plug, the plug and the socket are connected to each other;

[0006] It comprises: a sleeve block, which is movably sleeved on the outside of the plug, a fixing strip is fixed on the inside of the sleeve block, and a fixing groove is provided on the plug outside the fixing strip, and the fixing strip slides in contact with the plug through the fixing groove;

[0007] The adjusting mechanism is movable and runs through both ends of the sleeve block. A sealing assembly is provided at the end of the adjusting mechanism, and the movement of the sleeve block drives the adjusting mechanism to move synchronously, on the one hand, ensuring the tightness of the connection between the plug and the socket, and on the other hand, driving the sealing assembly to seal the gap between the plug and the socket.

[0008] Preferably, the adjustment mechanism comprises a movable rod passing through two ends of the sleeve block, and the movable rod and the sleeve block are slidably connected.

[0009] Preferably, a spring for returning the movable rod to its original position is wound around the outer side of the movable rod, a shift block is connected to one end of the movable rod, and a connecting plate is fixed to the other end of the movable rod.

[0010] Preferably, the sealing assembly includes a first air bag adhered to the side of the connecting plate, and a first channel is opened inside the connecting plate.

[0011] Preferably, the first airbag is connected to the air pipe through the first channel, and the air pipe is made of a hose material.

[0012] Preferably, the air delivery pipe is fixed between the connecting plate and the sleeve block, and the air delivery pipe is connected to the second air bag through the second channel.

[0013] Preferably, the second channel is arranged inside the sleeve block, and the second air bag is adhered to a side of the sleeve block close to the socket.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the waterproof sealed connector seals the gap at the connection between the plug and the socket by changing the thickness of the sealing structure, and can adaptively block the gap according to the size of the gap at the connection of different connectors, thereby ensuring the sealing of the connector after connection. The specific contents are as follows:

[0015] 1. Push the shift block to drive the movable rod to slide on the sleeve block, and then drive the connecting plate to move and separate from the plug. Then push the sleeve block to slide on the plug and move the sleeve block between the plug and the socket. Then release the pressure on the shift block. In this way, the spring resilience can drive the movable rod and the connecting plate to move in the opposite direction and get stuck at the connection between the plug and the socket to ensure the stability of the connector after connection.

[0016] 2. After the connection plate contacts the plug and the socket, the first airbag is squeezed, so that the gas in the first airbag can be transmitted to the second channel through the first channel and the air pipe, and finally enters the second airbag to drive it to expand, and the four sides of the gaps connected between the plug and the socket are blocked to ensure the sealing. Different connectors can achieve different states of expansion of the airbag according to the different extrusion states of the airbag, thereby meeting the sealing of gaps of different sizes.
