The plug-in cover 14 and the socket-in cover 214 are provided with hooks, and can be respectively mounted on the plug portion 12 and the jack portion 22, so that the connector is more practical and more convenient to detach.

The plug 10 and socket 20 assembly principle is: after the plug 10 is assembled, the female terminal 121 of the crimped wire is inserted, after the socket 20 is assembled, the male terminal 221 of the crimped wire is also inserted, the user firstly fixes the socket 20 on the mounting panel according to the requirement and then correctly inserts the plug 10 on the socket 20 according to the design structure of preventing from being inserted; at the beginning of the insertion, the first protrusion 31 on the push-pull pin 30 must be fixed at the position of the second positioning hole 1116 of the boss 111; the push-pull pin 30 is then pressed into the bottom, and the first protrusion 31 is fixed to the first positioning hole 1113 of the boss 111, thereby completing the locking and fixing of the plug 10 and the receptacle 20.

If the plug 10 is to be pulled out, the first protrusion 31 on the push-pull pin 30 is pulled from the position of the first positioning hole 1113 to the position of the second positioning hole 1116, then the plug 10 is grasped by hand and the pressing plate 1112 is pressed down, so that the latch hook 112 is positioned below the latch ring 211 to forcibly pull out the plug 10, and the pulling-out operation is completed.

The plug 10 and the socket 20 are matched to realize the functions of preventing false locking and preventing touching and secondary unlocking, and the specific steps are as follows:

virtual insertion prevention: the push-pull pin 30 must be as flat as the outer side wall of the first housing 11 after the connector is assembled as required, and if the push-pull pin 30 is inserted before it is already at the position of the first positioning hole 1113; when the plug 10 is inserted, when the latch hooks 112 on the plug 10 are led into the latch rings 211 on the socket main housing 213, the latch hooks 112 will deform in an internal pressure, so that the base plate 32 on the push-pull pin 30 interferes with the socket main housing 213 and cannot be inserted, and when the plug is forcibly inserted down, the push-pull pin 30 is ejected upwards and is not flat with the plug rear cover 115, so that a user can know that the plug is not installed in place, and the function of preventing the virtual insertion is realized.

Prevent touching secondary unblock function: after the plug 10 and the socket 20 are installed, the push-pull pin 30 is not pulled out to the position of the second positioning hole 1116, if a user wants to pull out the plug 10, the position of the push-pull pin 30 directly holding the plug 10 to press the pressing plate 1112 is fixed, the push-pull pin 30 directly abuts against the position of the pressing plate 1112 to influence the manual pressing, and the plug 10 cannot be pulled out without pulling the push-pull pin 30 and then pressing the pressing plate 1112; meanwhile, if the push-pull pin 30 is pressed against the pressing plate 1112 by an external force and still fixed at the position of the first positioning hole 1113, it is ensured that the lock hook 112 is not separated from the lock ring 211, and the anti-touch secondary unlocking function is realized.

In summary, the connector of the present invention has the following features:

1. the single-side lock catch can be realized, a balanced symmetrical stress plug structure is designed, the pressing plate 1112 and the anti-skid patterns are added, the plug 10 is more suitable for being pinched by hands, and the plug is reliable and convenient to plug.

2. The structure for realizing the functions of preventing false locking and preventing touching of the signal connector is broken through, and has the advantages of simple and reliable structure, small space and low cost.

3. The spring plate made of metal stainless steel is adopted to help the rebound of the lock hook 112; the pressing life of the boss is improved and the locking performance of the locking hook 112 and the locking ring 211 is improved.

4. The structure for detaching the professional tool is arranged on the socket insert cover 214 and the plug insert cover 14, so that the plug 10 and the socket 20 can be simply withdrawn and maintained, thereby reducing the maintenance cost of the connector and prolonging the service life of the connector.

5. The terminals are provided with anti-rotation straight structures on both the plug-in cover 14 and the receptacle-in cover 214 to facilitate the use of the connector in a variety of environments.

6. The receptacle 20 may provide for front mounting and rear mounting arrangements that allow for more options for the user; the rear mounting socket adopts a copper nut 215 structure, so that the service life of the rear mounting socket can be prolonged, and the screw torque of the rear mounting socket can be increased.

7. The installation of the plug 10 and the socket 20 has a multiple anti-insertion design structure, so that a user can conveniently select and install the plug 10 and the socket 20, and the 'fool' operation effect of the plug 10 and the socket 20 is realized.

8. The plug 10 and the socket 20 can have two kinds of installation structures with different insulation wall thicknesses and concurrent large and small terminals, so that the design of integrating small power connection and signal connection is realized, and the plug is convenient to use and saves cost.

The above set forth the product design of 26PIN, and for this series there are also 8PIN, 14PIN and 23PIN. The structure functions are the same, and the outline dimension is reduced or increased.
