[0028] In one embodiment of the present invention, Figures 1-2 As shown, a connector with terminal and housing anti-movement function is provided, which includes a plastic housing 10 and a PIN terminal 20.
[0029] Furthermore, if Figures 1 to 3 As shown, the plastic housing 10 has a front end and a rear end opposite to each other, the front end of the plastic housing 10 is provided with a pair of plug holes 11 extending toward the rear end thereof, the rear end of the plastic housing 10 is provided with a plurality of terminal plug holes 101 connected to the pair of plug holes 11, and the terminal plug holes 101 are provided with a stop step 12 facing the pair of plug holes 11;
[0030] Furthermore, if Figure 2 , 4 As shown, the PIN terminal 20 is provided with a stop shoulder 21 located between its two ends. The PIN terminal 20 is inserted into the terminal socket 101 from the direction of the socket 11 to prevent the PIN terminal 20 from retreating toward the rear end of the plastic housing 10 until the stop shoulder 21 abuts against the stop step 12, and the PIN terminal 20 is tightly fitted with the terminal socket 101.
[0031] The connector with terminal and shell anti-movement function provided by the embodiment of the utility model is implemented by providing a stop step 12 facing the opposite socket 11 in the terminal socket 101 on the plastic shell 10, and providing a stop shoulder 21 located between the two ends of the PIN pin terminal 20, and then the PIN pin terminal 20 is inserted into the terminal socket 101 from the opposite socket 11 until the stop shoulder 21 is abutted against the stop step 12, and it is ensured that the PIN pin terminal 20 is tightly matched with the terminal socket 101. Then, the PIN pin terminal 20 is limited by the stop shoulder 21 on the stop step 12, thereby preventing the PIN pin terminal 20 from retreating from the opposite socket 11 to the rear end of the plastic shell 10.
