Detailed Description

With reference to fig. 1 and 2, a connector includes a male plug 10 and a female plug 20, the male plug is provided with a step-shaped first limit structure, the female plug is provided with a step-shaped second limit structure, a conductive member of the male plug is disposed on the first limit structure, and a conductive member of the female plug is disposed on the second limit structure; be equipped with first annular structure 11 on the public lateral wall of inserting, female inserting is equipped with second annular structure 21 on the inside wall, and when first limit structure and the cooperation of second limit structure, first annular structure and the cooperation of second annular structure.

In actual operation, the male plug 10 is connected to the ballast, and the female plug 20 is connected to the lamp. When the male plug is matched with the female plug, the first limiting structure is matched with the second limiting structure, and when the conductive piece of the male plug is completely connected with the conductive piece of the female plug, the first annular structure 11 is matched with the second annular structure 21. The first annular structure 11 and the second annular structure 21 are matched to limit the relative displacement of the male plug 10 and the female plug 20 in the axial direction; the first limit structure and the second limit structure are matched to limit the relative rotation of the male plug and the female plug.

With reference to fig. 2 and 3, the first limiting structure includes a first step 12 and a second step 13, the first circular housing 100 is disposed in the male plug, and the first step and the second step are disposed in the first circular housing; the second limiting structure comprises a third step 22 and a fourth step 23, a second round shell 200 is arranged in the female plug, and the third step and the fourth step are arranged in the second round shell. When the male plug is matched with the female plug, the second circular shell is sleeved on the first circular shell to guide the matching of the male plug and the female plug. In addition, the first circular housing 100 protects the first limiting structure therein and the conductive member of the male plug. Similarly, the second circular housing 200 protects the second limiting structure therein and the conductive member of the female plug.

First limit structure can set up on first cylinder, and first cylinder interference fit is in first circular casing 100, and the head end of first wire is connected with the electrically conductive piece of public inserting, and the tail end of first wire extends to the afterbody of public inserting, is connected with the ballast. The second limiting structure can be arranged on the second cylinder, the head end of the second lead is connected with the conductive piece of the female plug, and the tail end of the second lead extends to the tail of the female plug and is connected with the lamp.

The first step 12 is provided with a first conductive via 14, the second step 13 is provided with a first conductive post 15, the third step 22 is provided with a second conductive post 24, and the fourth step is provided with a second conductive via 25. The first conductive hole position and the first conductive column are conductive pieces of a male plug; the second conductive hole position and the second conductive column are conductive pieces of the mother plug. The male plug is inserted into the female plug, and in the process of matching the first limiting structure and the second limiting structure, the first conductive column 15 of the male plug is inserted into the second conductive hole site 25 of the female plug, and synchronously, the second conductive column 24 of the female plug is inserted into the first conductive hole site 14 of the male plug.
