The PCB board 2 is mounted on a panel 8, and the panel 8 and the chassis housing 1 form a complete chassis.
The assembly of the PCB 2 and the chassis housing 1 is shown in fig. 3, and the arrow in fig. 3 is the direction of insertion of the PCB 2, so as to connect the plug 4 and the socket 3 in a plug-in manner. If the plug-in connection is correct, referring to fig. 4, the male pin 5 can be correctly inserted into the female pin 7, so that the plug 4 is connected with the socket 3, and the panel 8 connected with the PCB 2 is correctly covered with the chassis housing 1. If the plugging is wrong, referring to the square frame part in fig. 5, the panel 8 is blocked and located outside the chassis housing 1, the panel 8 cannot be correctly covered with the chassis housing 1, and referring to fig. 6, the position of the female pin 7 does not correspond to the position of the male pin 5 and cannot be plugged and connected, the female pin 7 abuts against the socket 3, and the plug 4 cannot be plugged into the socket 3, so that the plug 4 can be judged to be 180 ° upside down.
In practice, the aperture of the receptacle on the female pin 7 is provided with a chamfer greater than 45 ° and less than or equal to 75 °, preferably 60 °, so that the chamfer constitutes a long chamfer 702; the male pin 5 is rounded 502 at its end. In practical use, the male pin 5 and the female pin 7 are hidden in the chassis housing 1, and the insertion condition of the male pin and the female pin cannot be seen, so that a good guiding effect is very important under the condition of blind insertion, and the designed long chamfer 702 and the round head 502 can play a good guiding effect, so that the insertion lubrication is smooth.

Because the chassis shell 1 made of plastic cannot conduct electricity, the electric conduction among the PCB 2, the grounding guide plate 6, the female pin 7 and the male pin 5 is realized through the plug-in connection of the male pin 5 and the female pin 7. In actual use, the male pin 5 and the female pin 7 are connected in a plug-in manner, and the ground wire is connected to the ground hole 501 of the male pin 5, thereby realizing the grounding function. Moreover, as the male pin 5 and the female pin 7 are respectively arranged at the corresponding ends of the socket 3 and the plug 4, the plug-in connection of the male pin 5 and the female pin 7 plays a role in mechanical foolproof, and incorrect operation when the socket 3 and the plug 4 are connected is avoided, so that the socket 3 and the plug 4 can be ensured to be correctly connected, and the PCB 2 is correctly arranged in the case shell 1.
The case shell 1 adopts PC material with high strength, elastic coefficient and high impact strength; the grounding guide plate 6 can be made of brass, and has good electric conductivity and strong current carrying capacity; the main body of the female pin 7 is made of brass, and the crown spring 701 is made of beryllium copper, so that the female pin is good in conductivity, strong in current carrying capacity, good in elastic performance, capable of being inserted and pulled out for many times, free of deformation and long in service life; the male pin 5 is a brass copper rod, the rod body is thick, the current carrying capacity is high, the mechanical strength is high, the male pin is not easy to break, the internal thread at the tail part can be matched with a grounding wire, and the matching is stable.
The chassis housing 1 may be made of a material other than plastic, and the chassis housing 1 may be made of a material other than conductive. The ground guide 6 may be connected to the inside of the plug 4 for electrical conduction, in addition to being electrically conductive to the PCB 2 by fastening screws.
