[0030] In summary, the first connector 100, the second connector 300 and the combination thereof have the following beneficial effects: (1) By setting the positioning groove 14 and the terminal groove 15 partially overlapping in the front-rear direction, and the positioning groove 14 communicating to the terminal groove 15 in the front-rear direction, when the second connector 300 and the first connector 100 are docked, the positioning block 35 is accommodated in the positioning groove 14, not only avoiding the case that the size of the first housing 1 in the up-down and left-right directions is increased to ensure that the plastic positioning groove 14 has sufficient size, but also realizing the docking of the positioning groove 14 and the positioning block 35 without increasing the size of the first housing 1 in the up-down and left-right directions, which meets the trend of miniaturization of the connector, and when the first connector 100 or the second connector 300 is subjected to external force in the up-down or left-right direction, the assembled positioning block 35 and the positioning groove 14 can bear part of the external force, avoiding the case that when the terminal 2 bears most of the external force and moves or swings, the interaction force between the docking part of the terminal 2 and the second connector 300 becomes larger, and the terminal 2 is easily scratched or damaged.

[0031] (2) By setting the positioning groove 14 penetrating the first body forwardly, and the positioning groove 14 communicating to the terminal groove 15 rearwardly, the first wall surface 141 of the positioning groove 14 is closer to the insertion groove 13 than the second wall surface 142 of the positioning groove 14, and the terminal groove 15 has a third wall surface 151 opposite to the contact part 21 in the up-down direction, the third wall surface 151 is flush with the second wall surface 142, so that when the first housing 1 is injection molded, the mold for molding the mutually communicating positioning groove 14 and terminal groove 15 can be integrally arranged in the front-rear direction, and the part of the mold surface for molding the second wall surface 142 and the third wall surface 151 can be flatly arranged, which reduces the difficulty of mold manufacturing, and also reduces the molding difficulty of the mutually communicating terminal groove 15 and positioning groove 14.

[0032] (3) By setting along the front and back direction, the buckle part 16 and the positioning groove 14 at least partially overlap; the second shell 3 is provided with a lock part 34, the lock part 34 is used for buckling the buckle part 16, and along the front and back direction, the lock part 34 exceeds the positioning block 35, so that the lock part 34 is first matched with the buckle part 16, and the positioning block 35 enters the positioning groove 14, so that when the first connector 100 and the second connector 300 are connected, the lock part 34 is first matched with the buckle part 16, so that the relative position between the first shell 1 and the second shell 3 is fixed, the difficulty of subsequent positioning block 35 and positioning groove 14 is reduced, and the buckle part 16 is arranged above the positioning groove 14, the thickness of the plastic above the positioning groove 14 is increased, the anti-deformation ability is improved, so that when the first connector 100 or the second connector 300 receives external force along the left and right direction or the up and down direction, the positioning block 35 and the positioning groove 14 bear part of the external force, the groove wall of the positioning groove 14 is not easy to deform.

[0033] (4) By setting the positioning block 35 has a rear end face 351 and an avoiding face 352, the rear end face 351 is located in front of the terminal 2, and the avoiding face 352 is inclinedly extended from the rear end face 351 to the direction close to the insertion groove 13, which avoids the collision between the positioning block 35 and the front end of the terminal 2 after the first connector 100 and the second connector 300 are connected, so that even if the terminal 2 moves upward or forward due to the abutting of the connection part of the second connector 300, the positioning block 35 and the terminal 2 are not easy to contact or collide.

[0034] The above detailed description is only for the preferred embodiment of the application, not for the patent range of the application, so, any equivalent technical change based on the content of the application description and drawings is included in the patent range of the application.
