The connector has some problems in structure: when one of the terminal modules needs to be taken out of the insulating shell, the inserting strip needs to be taken out firstly to separate the locking between the terminal modules, and then the locking block on the terminal module needing to be taken out is unlocked with the insulating shell, so that the terminal module can be taken out relative to other terminal modules and the insulating shell freely. It can be seen that, for the connector, two structures for locking the terminal modules are arranged on the connector, two-step unlocking operation is required for taking out one terminal module, the operation process is complicated, and the dismounting efficiency is low.

On the left and right side walls of the housing 30 corresponding to the card slots 101 on the insulator 10, a plurality of openings 304 are provided to penetrate the left and right side walls of the housing 30, the openings 304 are arranged at intervals along the terminal module arrangement direction, and the number of the openings 304 is the same as the number of the terminal modules.

The number of the retaining arms 202 in the locking member 20 corresponds to the number of the openings 304 and the card slots 101, and is arranged at intervals along the arrangement direction of the terminal modules. The blocking arm 202 is a plate body with the same thickness as the width of the opening hole 304 and the width of the card slot 101, the part of the blocking arm 202 close to the connecting section 201 is a first part in blocking fit with the inner wall of the opening hole 304, the part of the blocking arm 202 far away from the connecting section 201 is a second part in blocking fit with the slot wall of the card slot 101, and the first part and the second part on the blocking arm 202 are connected and can be simultaneously locked and matched with the opening hole 304 and the card slot 101 after one insertion. A round hole is further formed in the connecting section 201, and an operator can use a tool to hook the hole wall of the round hole, and the locking piece 20 is driven to move relative to the shell 30 by pulling the tool.
