[0026] As Figures 1 to 3 shown, it is an embodiment of the present application:

[0027] A FAKRA connector with a CPA structure includes a plug connector and a socket connector that are inserted and cooperated with each other and detachably connected. The plug connector has a plug outer shell 1, and the socket connector has a socket outer shell 2. The CPA structure on the socket outer shell 2 is snap-connected to the plug outer shell 1. The CPA structure includes a cantilever 20 and a CPA reinforcement 30. The tail of the cantilever is integrally connected to the inner wall of the plug outer shell 1. A locking portion 21 is provided on the socket outer shell 2. The cantilever 20 is slidably connected to the locking portion 21. An interference fit is formed between the CPA reinforcement 30 and the locking portion 21 to enhance the holding force of the snap connection between the CPA structure and the socket outer shell 2.

[0028] It should be noted that the CPA reinforcement 30 is an independent integral part, which is simple to form and is fixed on the plug outer shell 1. The CPA reinforcement 30 includes a main body portion 301, side connection portions 302 that extend perpendicularly from both side edges of the main body portion 301 and are arranged oppositely, elastic portions 303 that extend from the side connection portions 302 and are symmetrically disposed on both sides of the main body portion 301, and abutting portions 304 that extend from the elastic portions 303. The abutting portions 304 form a clamping force on the locking portion 21 from both sides under the elastic force of the elastic portions 303 to enhance the holding force after the plug and the socket are assembled.

[0029] The elastic portion 303 is a "Ji"-shaped flat arm that extends parallel to the main body portion 301 from one end of the side connection portion 302, and forms an insertion space for the cantilever 20 between the elastic portion 303 and the main body portion 301. The cantilever 20 is horizontally inserted into the insertion space, which is simple to operate.
