Detailed Description
The technical solution protected by the present invention will be specifically described below with reference to the accompanying drawings.
Referring to fig. 1 and 2, a small-sized quick-locking waterproof connector mainly includes: the locking plate connector and the cable connector are in rotary buckle connection;
the locking plate connector includes: terminal, 1, gluey core A2, terminal A1 runs through and is fixed in the through-hole of gluey core A2, the one end of gluey core 2A is provided with buckle structure, as figure 3, buckle structure includes: the rubber core A2 comprises a step 21, wherein a notch 22 is formed in the step 21, one side wall of the notch 22 is an inclined surface, and a clamping groove 23 is formed between the step 21 and the rubber core A2 body;
the cable connector includes: the wire rod 11, the body 10, the terminal B9, the gluey core B8, terminal B9 runs through and is fixed in the through-hole of gluey core B8, rivet the reinforcement connection between wire rod 11 and the terminal B9, the body 10 is located outside terminal B9 and wire rod 11, be in gluey core B9 is close to the one end of gluey core A2 and is provided with cap B5, as shown in fig. 4, the inside wall department of cap 5B is provided with the stopper 51 that is the same with notch 22 quantity, the structure of stopper 51 and notch 22 phase-match, rotatory buckle connection between cap B5 and the gluey core A2.
