It should be noted that the abutment of the latch portion 1335 with the mounting member 12 can be used for limiting the second fixing structure 133 from being separated from the bayonet 1211 along the depth direction of the bayonet 1211, the abutment of the surface of the second extension portion 1334 facing the connecting portion 1331 with the wall of the bayonet 1211, and the abutment of the surface of the connecting portion 1331 facing the second extension portion 1334 with the mounting member 12 can be used for limiting the movement of the second fixing structure 133 relative to the mounting member 12 along the depth direction perpendicular to the bayonet 1211.

In this design, the first extension 1333, the second extension 1334 and the latch 1335 are connected to form a latching portion 1332 with a "hook" structure, so as to realize a snap fit with the bayonet 1211, thereby facilitating the installation and removal of the connector 13 and the installation component 12.

Further, as shown in fig. 6-7, in order to enhance the connection stability between the engaging portion 1332 and the bayonet 1211, it is further designed that the first extending portion 1333 includes a main plate 1336 connected to the connecting portion 1331 and side plates 1337 connected to two sides of the main plate 1336, the second extending portion 1334 is connected to one end of the main plate 1336 away from the connecting portion 1331, and the second extending portion 1334, the main plate 1336, the side plates 1337 and the connecting portion 1331 together enclose a groove 1338.

In this design, when the engaging portion 1332 is engaged with the bayonet 1211, the second extending portion 1334, the main plate 1336, the side plate 1337 and the connecting portion 1331 together form the groove 1338, so that the contact area between the engaging portion 1332 and the bayonet 1211 is increased, and the connection stability between the engaging portion 1332 and the bayonet 1211 is enhanced.

As shown in fig. 4, 6 and 7, considering that the hook 1335 abuts against the mounting element 12, the second fixing structure 133 can be restricted from being separated from the bayonet 1211 along the depth direction of the bayonet 1211, the surface of the second extending portion 1334 facing the connecting portion 1331 abuts against the mouth wall of the bayonet 1211, the surface of the connecting portion 1331 facing the second extending portion 1334 abuts against the mounting element 12, the second fixing structure 133 can be restricted from moving relative to the mounting element 12 along the depth direction perpendicular to the bayonet 1211, and the connection stability between the connecting element 13 and the mounting element 12 is further enhanced, so that the design is further improved, the mounting element 12 is provided with the accommodating cavity 1214 for installing the connecting element 13, the second fixing structure 133 further includes the limiting portion 1340, the limiting portion 1340 is disposed on the surface of the connecting portion 1331 facing the second extending portion 1334, the mounting element 12 further includes the matching portion 1212 matching with the limiting portion 1340, the limiting portion includes one of the protrusion 1341 and the limiting slot 1213, the mating portion 1212 includes the other of the protrusion 1341 and the limit notch 1213, and the protrusion 1341 and the limit notch 1213 extend along a direction (i.e., a mounting direction) in which the connector 13 is mounted in the accommodating cavity 1214.

The engagement between the limiting portion 1340 and the engaging portion 1212 may be an insertion engagement or a snap engagement, and the specific engagement between the limiting portion 1340 and the engaging portion 1212 depends on the specific structures of the limiting portion 1340 and the engaging portion 1212.

The position-limiting portion 1340 may be a protrusion 1341 or a position-limiting notch 1213, when the position-limiting portion 1340 is the protrusion 1341, a surface portion of the second extending portion 1334 facing the connecting portion 1331 extends toward the connecting portion 1331 to form the protrusion 1341, and when the position-limiting portion 1340 is the position-limiting notch 1213, a surface portion of the second extending portion 1334 facing the connecting portion 1331 extends away from the connecting portion 1331 to form the position-limiting notch 1213.

The mating portion 1212 may be a limit slot 1213 or a protrusion 1341, when the mating portion 1212 is the limit slot 1213, a surface portion of the connecting portion 1331 facing the second extending portion 1334 extends toward the second extending portion 1334 to form the protrusion 1341, and when the mating portion 1212 is the protrusion 1341, a surface portion of the connecting portion 1331 facing the second extending portion 1334 extends away from the second extending portion 1334 to form the limit slot 1213.

In this design, the movement of the second fixing structure 133 relative to the mounting member 12 in the direction perpendicular to the direction in which the connecting member 13 is inserted into the accommodating cavity 1214 can be effectively limited by the cooperation between the limiting portion 1340 and the engaging portion 1212, so that the connection stability between the connecting member 13 and the mounting member 12 is further enhanced.

The structure of the protrusion 1341 and the limiting slot 1213 can be implemented in several ways, but not limited to the following embodiments.

In one embodiment, the limiting portion 1340 is a protrusion 1341, the matching portion 1212 is a limiting slot 1213, the protrusion 1341 is a dot protrusion 1341, and the corresponding limiting slot 1213 is a dot slot, when the protrusion 1341 is engaged with the limiting slot 1213, the surface of the dot protrusion 1341 is completely attached to the slot wall of the dot limiting slot 1213, so that the dot protrusion 1341 is engaged with the dot limiting slot 1213, so as to limit the second fixing structure 133 from moving along another depth direction perpendicular to the bayonet 1211 relative to the mounting member 12.

As shown in fig. 4 and 7, in an embodiment, the limiting portion 1340 is a protrusion 1341, the matching portion 1212 is a limiting slot 1213, the protrusion 1341 is a long-strip protrusion 1341, the long-strip protrusion 1341 is disposed along a direction perpendicular to the bearing surface 1311 of the base 131, the corresponding limiting slot 1213 is a long-strip slot, and the long-strip protrusion 1341 is inserted into and matched with the long-strip limiting slot 1213 along a depth direction of the bayonet 1211 to limit the second fixing structure 133 from moving relative to the mounting component 12 along another depth direction perpendicular to the bayonet 1211.

Further, as shown in fig. 6 to 7, considering that before the engaging portion 1332 is engaged with the bayonet 1211, the second extending portion 1334 contacts with the opening wall of the bayonet 1211, and the opening wall of the bayonet 1211 presses the second extending portion 1334 and deforms the second extending portion 1334 in a direction away from the connecting portion 1331, so that the second extending portion 1334 is deformed by the pressing action of the opening wall of the bayonet 1211 to facilitate the engaging and detaching between the second fixing structure 133 and the bayonet 1211, it is further designed that the connecting portion of the first extending portion 1333 and the second extending portion 1334 is recessed to form at least one notch 1339. Specifically, in the present embodiment, the number of the notches 1339 is two, and the two notches 1339 are respectively located at two sides of the second extending portion 1334.

In this design, the design of the notch 1339 reduces the contact area between the first extension 1333 and the second extension 1334, so that when the mouth wall of the bayonet 1211 presses the second extension 1334, the second extension 1334 is deformed conveniently, thereby facilitating the snap-fit installation and detachment between the second fixing structure 133 and the bayonet 1211.
