Detailed Description

The waterproof connector according to the embodiment of the present invention will be further described with reference to fig. 1 to 10.

Example 1: a waterproof connector comprises a socket 1 and a plug 2, wherein one end of the plug 2 is fixedly provided with a pin 21 (three pins 21 are adopted in the embodiment), the socket 1 is provided with a cavity 11, the size of the cavity 11 is matched with that of the plug 2, and the cavity 11 is internally provided with a jack 12 matched with the pin 21, so that when the pin 21 is inserted into the jack 12, the plug 2 can be ensured to be embedded into the socket 1, and an electric shock prevention effect is achieved. The one end of the relative plug of socket 1 is equipped with one and can wraps cavity 11 completely to can closely laminate the buckler 3 on socket 1's terminal surface, buckler 3 is formed by two bucklers 32 concatenations at least (this embodiment is got 4 bucklers 32 and is constituted buckler 3), buckler 32 is equipped with turn-ups 321 in concatenation department, the existence of turn-ups 321 can let buckler 32 seal in concatenation department, can prevent that water from getting into along concatenation department. The other end of the plug 2 opposite the pin 21 is provided with a hollow boss 22, and the boss 22 and the waterproof cover 3 are connected by a hinge, so that the waterproof cover 3 can rotate around the hinge. The boss 22 is fixedly connected with a hollow wire inlet rod 221, so that the circuit of the plug pin 21 is connected with the outside through the hollow boss 22 and the hollow wire inlet rod 23, and the wire inlet rod 23 is provided with a control mechanism 24. The other side of the waterproof cover 3 opposite to the plug pins 21 is tightly pasted with a rubber ring 31 by strong glue, and the rubber ring 31 is sleeved on the wire inlet rod 23, so that water can not enter the plug 2 and the socket 1 from a gap where the rubber ring 31 is jointed with the wire inlet rod 23. So that when the plug 2 is inserted into the socket 1; the four waterproof covers 3 are closed (as shown in fig. 3), and each waterproof cover 3 is tightly attached to the end face of the socket 1, so that the plug 2 is inserted and pulled out when the hand is wet, the wire inlet rod 23 is held, the waterproof covers 3 separate the hand from the plug 2, the hand is prevented from directly contacting with the plug 2, and the purpose of preventing water from entering the waterproof connector can be achieved. Moreover, the waterproof cover 3 can completely cover the concave cavity 11 and can be tightly attached to the end face of the socket 1, and the waterproof cover can also play a role in electric shock prevention. When the plug 2 and the socket 1 are separated, the control mechanism 24 can be slid outwards along the wire inlet rod 23 to open the four waterproof covers 3 (as shown in fig. 4), so that the plug 2 and the socket 1 can be separated conveniently.

The control mechanism 24 includes a sliding sleeve 241 and a locking mechanism 242, the sliding sleeve 241 is sleeved on the end of the wire inlet rod 23 far away from the waterproof cover 3, and the locking mechanism 242 is arranged on the wire inlet rod 23 and is used for locking the sliding sleeve 241. Locking mechanism 242 includes resilient latch 2421, groove 2422, button 2423, and latch 2424. The elastic fixture 2421 is arranged on the outer surface of the wire inlet rod 23 and on one end 3 far away from the waterproof cover, and the plane where the elastic fixture 2421 is located is between the wire inlet rod 23 and the sliding sleeve 241, so that the sliding sleeve 241 can be locked by the elastic fixture 2421 when not sliding. The two grooves 2422 are arranged along the axis of the wire feeding rod 23, and the distance between the two grooves 2422 can ensure that the waterproof cover 3 is opened. Each of the elastic stoppers 2421 further includes a button 2423 for facilitating the pressing of the elastic stopper 2421. One surface of the button 2423 is connected with the elastic fixture 2421, the other surface of the button 2423 is slightly higher than the groove 2422, and the peripheral side surface of the button 2423 is also provided with a buckle 2424. When it is desired to slide sliding sleeve 241, button 2423 is depressed to depress resilient latch 2421, and button 2423 is flanked by catches 2424, thereby preventing button 2423 from disengaging sliding sleeve 241. The edge part of the waterproof cover 3 is connected with the control mechanism 24 through the pull rope 4, and the waterproof cover 3 can be opened or retracted along the control mechanism 24 which slides along the axial direction of the wire inlet rod 23 under the action of the pull rope 4.

Be equipped with screw thread 231 on the surface of inlet wire pole 23 near plug 2 one end, blind hole 221 has also been seted up to boss 22, also is equipped with screw thread 231 in the blind hole 221, and inlet wire pole 23 and boss 22 come the cooperation through screw thread 231 to guarantee the fixed between inlet wire pole 23 and the boss 22, when plug 2 damaged, the existence of screw thread 231 also can conveniently be changed moreover. The end face of each waterproof cover 3 contacting with the socket 1 is provided with a rubber gasket 5, the rubber gasket 5 can ensure that the contact face of the waterproof cover 3 and the socket 1 is tightly attached, so that water can be prevented from entering the waterproof connector (in the embodiment, the end face of the waterproof cover 3 contacting with the socket 1 can be sealed and waterproof by a magnetic sheet 6, namely, the contact face of the waterproof cover 3 and the contact end face of the socket 1 are respectively provided with the magnetic sheets 6 with opposite magnetism, so that the effect of sealing, preventing water from entering can be achieved by mutual attraction of the magnetic sheets 6). The contact surface between the waterproof covers 3 and the waterproof covers 3 is provided with the ultrathin magnetic sheet 6 with the size consistent with that of the contact surface, the magnetic sheet 6 is adhered to the contact surface by glue, and the magnetism is opposite, so that the contact between each waterproof cover 3 is ensured to be tight, and water can be prevented from entering the waterproof connector from the contact surface of the waterproof cover 3.

Example 2: the structure is roughly as shown in embodiment 1, wherein the waterproof cover 3 is a whole waterproof cover 3 formed by waterproof cloth 33, the structure is similar to an umbrella, and the waterproof cloth 33 can completely cover the whole plug 2 and tightly fit on the end face of the socket 1 through the support of the framework 8. One end of the frame 8 is hinged with the rubber ring 31, so that the frame 8 can slide along the direction of the wire inlet rod 23 with the rubber ring 31, and the frame 8 can rotate around the rubber ring 31. The other end of skeleton 8 is equipped with the continuation limit of a circular arc structure, and the arc mouth orientation of circular arc is opposite with inlet wire pole 23 place one side, and when strutting waterproof cover 3 like this, the continuation limit can guide waterproof cover 3 more easy opening (like fig. 9), compares in not having the continuation limit or the arc mouth orientation is unanimous with inlet wire pole 23 place one side and prolongs the limit, and waterproof cover 3 is when strutting along socket 1 terminal surface, the dead condition of card can not appear.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
