[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figures 1 to 4The utility model provides a technical solution: a firmly assembled HDMI female socket, comprising a front shell 1, a rear shell 2 installed inside the front shell 1, and a connecting foot 10 arranged on the rear shell 2, a contraction part 5 is arranged on both sides of the front shell 1, and the contraction part 5 is used to apply a clamping force to the convex edge 6, so that the front shell 1 and the rear shell 2 are fixed more firmly, and a second elastic sheet 11 is arranged at one end of the contraction part 5, and one end of the second elastic sheet 11 is used to be inserted into the card slot 13 to prevent the rear shell 2 from being separated from the front shell 1, thereby ensuring that the front shell 1 and the rear shell 2 are firmly assembled. The rear shell body 2 is provided with a convex edge 6 which cooperates with the contraction portion 5, and a card slot 13 which cooperates with the second elastic sheet 11 is provided at the bottom of the convex edge 6. A groove 7 is provided on the rear side of the rear shell body 2, and a first elastic sheet 9 which cooperates with the groove 7 is provided at the bottom of the front shell body 1. The first elastic sheet 9 is used to prevent the rear shell body 2 from being separated from the front shell body 1, so that the fixation between the front shell body 1 and the rear shell body 2 is more secure. A convex block 8 for blocking the first elastic sheet 9 is provided on the groove 7. The convex block 8 is used to prevent the first elastic sheet 9 from bending downward, losing the blocking effect on the rear shell body 2, and improving reliability.

[0018] The second elastic piece 11 is arranged to be inclined upward.

[0019] Among them, an alignment block 4 is provided on the outer side of the rear shell 2, and an alignment groove 12 matching the alignment block 4 is opened on the front shell 1. The alignment block 4 and the alignment groove 12 cooperate to prevent the front shell 1 and the rear shell 2 from shifting up and down, making the assembly more secure.

[0020] Two pins 3 are provided on both sides of the front shell 1. By providing a plurality of pins 3, it is ensured that the front shell 1 can be more firmly welded to the PCB board.

[0021] The protrusion 8 is a hemispherical structure. The protrusion 8 is set as a hemispherical structure, so that during assembly, the protrusion 8 can be avoided by simply bending the first elastic sheet 9 outwards a short distance.

[0022] Specifically, during assembly, the first elastic sheet 9 is bent downward to a position where it will not block the rear shell 2, and then the rear shell 2 is inserted into the front shell 1, the alignment block 4 is inserted into the alignment groove 12, and the convex edge 6 enters the inner side of the contraction portion 5, and the contraction portion 5 clamps the convex edge 6. During the entry process, the convex edge 6 will first squeeze the second elastic sheet 11 into a horizontal state. When the rear shell 2 is blocked by the front shell 1 and cannot be further inserted, the second elastic sheet 11 is just aligned with the card slot 13, and the second elastic sheet 11 pops open and resets and is carded into the card slot 13, blocking the rear shell 2 from separating from the front shell 1. At this time, the first elastic sheet 9 is below the groove 7. If the first elastic sheet 9 is released, the first elastic sheet 9 will be blocked by the protrusion 8 and cannot be reset normally. The first elastic sheet 9 is bent outward for a distance to avoid the protrusion 8, so that the first elastic sheet 9 can be reset normally, so that the first elastic sheet 9 can prevent the rear shell 2 from separating from the front shell 1, and the assembly is completed.
