AI Technical Summary
The assembly yield and installation stability of the fixing seat in the existing card edge connector are insufficient, and it is easy to detach due to dimensional errors or poor interference effect.
The first and second bases, which adopt a dovetail groove structure, are locked together. The first locking block is engaged with the second assembly groove to achieve structural interference, thus realizing precise fastening and stable structural engagement.
It improves assembly yield and installation stability during the manufacturing process, prevents detachment, and ensures precise alignment and strength of the mounting bracket.

Description
TECHNICAL FIELD
[0001] The utility model relates to a connector, in particular to a card edge connector. BACKGROUND
[0002] The current card edge connector can be used to insert the card edge into the card slot of the card edge connector at different insertion angles. Figure 1 As shown in the figure, two rows of terminals 10 in the card edge connector 1 are inserted into the fixed seat 12, and each fixed seat 12 is positioned and fixed by the positioning column 120 and the positioning hole 122 between each other, and then inserted into the main structure 14 of the card edge connector. The positioning and fixing of each fixed seat 12 by the positioning column 120 and the positioning hole 122 is mainly fixed by the structure interference method, so it is easy to cause size error or poor interference effect, resulting in poor fixing effect of each fixed seat 12 and separation, which reduces the assembly yield.
[0003] Therefore, how to improve the assembly yield and installation stability of the fixed seat for inserting the terminal in the card edge connector is a problem that needs to be solved by relevant technical personnel. CONTENT OF THE UTILITY MODEL
[0004] The utility model provides a card edge connector, which aims to solve the above technical problems.

[0006] Preferably, the insulating shell defines a plurality of card slots.
[0007] Preferably, the utility model further comprises a plurality of positioning pieces, each positioning piece being inserted into the card slot.
[0008] Preferably, the first assembly groove and the second assembly groove are dovetail groove structures.
[0009] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:
[0010] The first seat body and the second seat body are clamped to each other by the structural interference of the first clamping block in the first seat body being buckled into the second assembling slot of the second seat body in the second terminal set, so that precise buckling, stable structural clamping and effective anti-falling are achieved, and the yield during the manufacturing process is improved.

DETAILED DESCRIPTION
[0017] Please refer to Figure 2 and Figure 3 Fig. 2 and Fig. 3 are a three-dimensional schematic view and a three-dimensional exploded schematic view of the card edge connector. The card edge connector 2 mainly comprises an insulating shell 20, a first terminal set 22 and a second terminal set 24. The insulating shell 20 defines at least one socket 200 and a plurality of clamping grooves 202. The socket 200 is provided for the first terminal set 22 and the second terminal set 24 to be inserted and arranged.
[0018] The first terminal set 22 comprises a plurality of first terminals 220 and a first seat body 222 for the first terminals 220 to be inserted and arranged. The first seat body 222 forms at least one first clamping block 2220 and a first assembling slot 2222 adjacent to the first clamping block 2220. The second terminal set 24 comprises a plurality of second terminals 240 and a second seat body 242 for the second terminals 240 to be inserted and arranged. The second seat body 242 forms a plurality of second clamping blocks 2420 and a second assembling slot 2422 between the second clamping blocks 2420.
[0019] The card slot 202 in the insulating shell 20 can be used for inserting and installing the positioning sheet 26. The positioning sheet 26 can be used for positioning and fixing the position of the card edge connector 2 before terminal welding.
[0020] Referring to Figure 4 As shown in the figure, it is a schematic diagram of the assembling action of the combination of the first seat body in the first terminal group and the second seat body in the second terminal group. Figure 4 The second terminal 240 in the first terminal group 22 is intentionally omitted to facilitate clear understanding of the installation process. When the first terminal group 22 and the second terminal group 24 are installed, the second assembling groove 2422 in the second seat body 242 corresponds to the first clamping block 2220 in the first seat body 222, and after buckling, structural interference is performed to make the first seat body 222 and the second seat body 242 mutually clamped, and since the first assembling groove 2222 and the second assembling groove 2422 are both dovetail groove structures, whether the first assembling groove 2222 and the second clamping block 2420 or the second assembling groove 2422 and the first clamping block 2220 are combined, through the dovetail groove structure, not only can accurate alignment be achieved, but also the assembling stability after installation and the bonding strength after fixation are greatly improved, to achieve precise buckling and stable structure clamping and effectively prevent falling, thereby improving the yield during the process.
