By arranging the widened portion 1b to protrude outwards relative to the main body portion 1a on both sides in the transverse direction and arranging the connection mechanism at one side of the slot 13 in the transverse direction and arranging the connection mechanism at a position with relatively more insulating materials, the influence of the connection mechanism on the structural strength of the connector assembly is reduced, and the connection mechanism is arranged farther away from the slot 13 than the terminal slot 14 in the transverse direction, so that the widened portion 1b and the tower portion 3 are assembled and connected by utilizing the space of the widened portion 1b protruding outwards relative to the main body portion 1a, the conductive terminal 2 of the electric connector 100 is not easily touched, the performance of the electric connector 100 is not affected, and the connection stability of the widened portion 1b and the tower portion 3 is enhanced by arranging two connection mechanisms on both sides of the slot 13 in the transverse direction; in addition, the two opposite outer surfaces of the widened portion 1b in the transverse direction are disposed flush with the two opposite outer surfaces of the tower portion 3 in the transverse direction, so that the appearance of the tower portion 3 and the widened portion 1b is relatively neat and beautiful.

5. By arranging the two locking devices 200 and the two widened portions 1b, the connector assembly is symmetrically arranged, so that the electronic card 300 can be better protected, and the electrical connection stability of the connector assembly and the electronic card 300 in butt joint is improved.

6. Since the widened portion 1b protrudes outward in the transverse direction with respect to the main body portion 1a, the mounting groove can be provided farther away from the insertion groove 13 with respect to the terminal groove 14 in the transverse direction, the distance between the terminal groove 14 and the mounting groove is increased, the structural strength of the insulating body 1 between the terminal groove 14 and the mounting groove is enhanced, and damage to the widened portion 1b due to too close spacing of the terminal groove 14 and the mounting groove when the tower portion 3 is assembled to the widened portion 1b is avoided.

7. The mounting groove is provided with the protruding block 16, the clamping arm is provided with the clamping hook 37, and the clamping hook 37 is buckled on the protruding block 16 so as to connect the clamping arm with the mounting groove in a buckled manner, and prevent the clamping arm from being separated from the electric connector 100 in the longitudinal direction.

8. By extending the gap P to a side of the clamping arm corresponding to the clamping arm in the lateral direction and facing away from the hook 352, the tool groove is used for a tool to push the operation portion 353 to bias the clamping arm towards the gap P, so that the hook 352 is disengaged from the engagement with the protrusion 16.

9. Because the upper end of the terminal slot 14 needs to be subjected to force displacement by the contact portion 21, the lower end of the terminal slot 14 is used for fixing the middle portion 23, so that the upper end of the terminal slot 14 needs a larger space in the transverse direction, the space needed by the lower end is not so large, in order to ensure the strength of the terminal slot 14 and the first mounting slot 15a, the slot diameter of the first mounting slot 15a in the transverse direction needs to be smaller, the second mounting slot 15b is positioned below the first mounting slot 15a, the position, close to the mounting surface 12, of the widened portion 1b in the plugging direction is more plastic material, the second mounting slot 15b is arranged closer to the slot 13 than the first mounting slot 15a in the transverse direction, the largest dimension of the second mounting slot 15b in the transverse direction is set larger than the largest dimension of the first mounting slot 15a in the transverse direction, by reasonably utilizing the space, not only the widened portion 1b is ensured to form the first mounting slot 15a and the second mounting slot 15b, and the whole strength of the electric connector can be further increased, and the strength of the electric connector can be further increased by assembling the electric connector with the second mounting slot 200 b.

10. The tower part 3 protrudes in the plugging direction compared with the ear clip 4, so that the tower part 3 not only can protect the electronic card 300 with a common height, but also can protect the heightened electronic card 300, thereby increasing the application scene of the connector assembly, improving the competitive power of similar products in the market, and the wrenching part 43 at least partially exposes the tower part 3 towards one side far away from the slot 13 in the longitudinal direction, so that the ear clip 4 is conveniently opened.

11. The tower part 3 is an integrally formed plastic member, namely, the structure of the tower part 3 is not easy to separate, so that the strength of the tower part 3 is enhanced.

12. By extending the ribs 34 beyond the openings 331 in the plugging direction and toward the most distal end to the tower 3, the strength of the tower 3 is enhanced.

The above detailed description is merely illustrative of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model, so that all equivalent technical changes that can be made by the present specification and illustrations are included in the scope of the utility model.
