The positions and numbers of the extensions 22 and the grooves 221 can be adjusted according to the number and position of the actual stoppers 14, and are not limited here.

[0072] Next, please refer to the floating part 3. Figure 5 and Figure 6 . Figure 5 FIG. 1 is a top view of the card edge connector 100 . Figure 6The figure shows a partial schematic diagram of the card edge connector 100. The floating member 3 can be floatingly arranged in the second accommodation space S2. The floating member 3 includes a second body 31, a second opening 32, a plurality of second accommodation grooves 33 and two protrusions 34. Among them, the second opening 32 is formed on the second body 31 along the second direction D2, the second accommodation grooves 33 are arranged adjacently on the second body 31 along the first direction D1, the second accommodation grooves 33 can be provided for the local contact unit 4, and the second body 31 and the second accommodation grooves 33 jointly define a third accommodation space S3, and the third accommodation space S3 can be provided for the second docking card 300 to be inserted. In addition, the protrusions 34 are formed on both sides of the second body 31 and are arranged in the second accommodation space S2. It should be noted that the number of the protrusions 34 in this embodiment is two as an example, and the position and number of the protrusions 34 can be adjusted according to the actual combination situation, which is not limited here.

[0073] Please also read Fig. 9 The contact unit 4 is arranged adjacently along the first direction D1 and disposed between the rubber core 1 and the rear cover 2. The contact unit 4 includes a plurality of first contact members 41, a plurality of second contact members 42, and a plurality of connecting members 43, each of which is connected between each of the first contact members 41 and each of the second contact members 42. The first contact member 41 is disposed in the corresponding first receiving groove 13, and the first contact member 41 partially extends to the first receiving space S1. The second contact member 42 is disposed in the corresponding second receiving groove 33, and the second contact member 42 partially extends to the third receiving space S3.

[0074] In detail, Figure 7 As shown, each of the first contact members 41 further includes a first fixing portion 411 and a first contact portion 412, and each of the second contact members 42 further includes a second fixing portion 421 and a second contact portion 422. The first fixing portion 411 is inserted and fixed in each of the first receiving grooves 13, and the first contact portion 412 partially extends to the first receiving space S1. The second fixing portion 421 is inserted and fixed in each of the second receiving grooves 33, and the second contact portion 422 partially extends to the third receiving space S3. The first contact portion 412 of the first contact member 41 partially contacts the first docking card board 200, and the second contact portion 422 of the second contact member 42 partially contacts the second docking card board 300.

[0075] The connection relationship between the card edge connector 100 of the present invention and the first docking card board 200 and the second docking card board 300 is described in detail below. Figure 5 , Figure 7 and Figure 8As shown, when the first docking card board 200 and the second docking card board 300 of the card edge connector 100 are electrically connected, the first docking card board 200 is inserted into the first accommodation space S1 through the first opening 12 along the third direction D3, and the second docking card board 300 is inserted into the third accommodation space S3 through the second opening 32 along the second direction D2. At this time, the first docking card board 200 and the second docking card board 300, which are respectively inserted, form a first angle W1. On the other hand, as Fig. 9 As shown, the first fixing portion 411 of each first contact member 41 and the second fixing portion 421 of each second contact member 42 form a second angle W2. In this embodiment, the first direction D1 and the third direction D3 are perpendicular to each other, and the second direction can be adjusted according to the position of the second opening of the floating member 3, and is determined by the first angle W1 presented by the first docking card board 200 and the second docking card board 300. In detail, when the first docking card board 200 and the second docking card board 300 are inserted into the card edge connector 100 of the present invention, the first angle W1 formed by the first docking card board 200 and the second docking card board 300 has an angle range between 45 degrees and 135 degrees, and the second angle W2 formed by the first contact member 41 and the second contact member 42 is 90 degrees. In other words, the position of the first docking card board 200 inserted into the first accommodating space S1 is fixed, but the position of the second docking card board 300 inserted into the third accommodating space S3 is adjustable, which is equivalent to that the first angle W1 can be adjusted. In addition, the first fixing portion 411 of each first contact member 41 is fixed to the first receiving groove 13 of the rubber core 1 , and the second fixing portion 421 of each second contact member 42 is fixed to the second receiving groove 33 of the floating member 3 , so that the second angle W2 is fixed to 90 degrees.

[0076] In one embodiment of the present case, when the floating member 3 is tiltedly disposed in the second accommodation space S2 so that the second opening 32 is tiltedly disposed in the second accommodation space S2, the second docking card 300 is inserted into the third accommodation space S3 along the second opening 32. At this time, the angle range of the first angle W1 can be greater than or equal to 45 degrees and less than 90 degrees (such as Figure 7The first contact portion 412 of each of the first contact members 41 is smaller than the second contact portion 422 of each of the second contact members 42. In other words, the length of the second contact portion 422 is greater than the length of the first contact portion 412, and the areas for contacting the first docking card board 200 and the second docking card board 300 are equal in length. The difference is that the second contact portion 422 is used to connect to the area at the bottom of the second fixing portion 421, and it has an extra extension portion, so that the area for contacting the docking card board can be tilted. This design can provide the second docking card board 300 with a tilted insertion into the third accommodating space S3 and interfere with the second contact portion 422 according to the connection environment required by the actual connector without changing the assembly of the first fixing portion 411 and the second fixing portion 421. In more detail, in this embodiment, the first angle is preferably 78 degrees. In addition, when the angle range of the first angle W1 is between greater than 90 degrees and 135 degrees (not shown), the second contact portion 422 connected to the second fixing portion 421 is mirror-inverted. At this time, the avoidance space between the rubber core 1 and the rear cover 2 is adjusted along the position of the second opening 32 of the floating member 3, so that the second docking card plate 300 is inserted into the third accommodating space S3 along the second direction D2 determined by the first angle W1.

[0077] In another embodiment of the present case, when the floating member 3 is vertically disposed in the second accommodation space S2, so that the second opening 32 is vertically disposed in the second accommodation space S2, the second docking card plate 300 is inserted into the third accommodation space S3 along the second opening 32, at this time, the angle of the first angle W1 is 90 degrees (not shown), and the length of the first contact portion 412 of each of the first contact members 41 is equal to the length of the second contact portion 422 of each of the second contact members 42. In other words, the shape of the first contact member 41 at this time is exactly the same as the shape of the second contact member 42, that is, the first contact portion 412 is exactly the same as the second contact portion 422, and is only flipped 90 degrees.

[0078] The floating manner of the floating member 3 in the card edge connector 100 is further described. Figures 5 to 8 As shown, there is a gap G between the floating member 3 and the rubber core 1 and the rear cover 2, including the gap G generated between the protrusion 34 of the floating member 3 and the rubber core 1, so that when the floating member 3 is assembled between the rubber core 1 and the rear cover 2, the floating member 3 is provided to be limited in the second accommodation space S2 in the first direction D1 and the third direction D3. On the other hand, when the second docking card 300 is disposed in the third accommodation space S3, the gap G provides the second accommodation space S2 to allow the floating member 3 to move back and forth relative to the rubber core 1 and the rear cover 2 in the first direction D1, so that the second docking card 300 has a floating effect when inserted into the floating member 3.

[0079] It should be noted that in the embodiment of the card edge connector 100 of the present invention, the contact unit 4 is made of metal material, and the rubber core 1 , the rear cover 2 and the floating member 3 are all made of plastic material.

[0080] In another embodiment of the present invention, please refer to Fig.10 and Fig.11 . The difference from the previous embodiment is that the structures of the rubber core 1, the rear cover 2 and the floating member 3 of this embodiment are slightly different. Only the differences are described below, and the same technical content is not repeated here. In detail, in this embodiment, the rubber core 1 also includes two first snap-fit ​​blocks 15 and two locking portions 16. The two first snap-fit ​​blocks 15 are respectively formed on the corresponding two sides of the first body 11, and each first snap-fit ​​block 15 is partially disposed in the first accommodating space S1. The locking portions 16 are respectively formed at the corresponding two ends of the first body 11. The floating member 3 also includes four second snap-fit ​​blocks 35. Each pair of second snap-fit ​​blocks 35 are respectively formed on the corresponding two sides of the second body 31, and each second snap-fit ​​block 35 is partially disposed in the third accommodating space S3. On the other hand, the first docking card board 200 and the second docking card board 300 respectively have corresponding recessed parts. When the first docking card board 200 is inserted into the first accommodating space S1 and the second docking card board 300 is inserted into the third accommodating space S3, the corresponding recessed parts can abut the first engaging block 15 and the second engaging block 35, which has the function of ensuring that the first docking card board 200 and the second docking card board 300 are engaged and fixed. Furthermore, the locking part 16 can be a screw fixing structure for the card edge connector 100 to be locked on the printed circuit board. It should be noted that in this embodiment, the number of the first engaging block 15 and the locking part 16 is two as an example, and the number of the second engaging block 35 is four as an example. Their positions and numbers can be adjusted according to the actual setting situation and are not limited here.

[0081] As mentioned above, in this embodiment, the rubber core 1 and the rear cover 2 each have a clamping member C, which is formed on one side of the rubber core 1 and the rear cover 2 close to the second docking card 300, respectively. Fig.10 As shown, each clamping member C presents a T-shaped protruding structure. When the card edge connector 100 is automatically assembled on the printed circuit board, when a clamp having a corresponding clamping member C is used for clamping, the positioning is corrected to ensure that the position of each clamping is fixed, thereby improving the accuracy of assembly. In addition, when the second docking card board 300 is set in the third accommodating space S3, the gap G provides a second accommodating space S2 to allow the floating member 3 to move back and forth relative to the rubber core 1 and the rear cover 2 in the first direction D1 and / or the third direction D3, so that the second docking card board 300 has a floating effect when inserted into the floating member 3.

[0082] In summary, the card edge connector of the utility model includes a connection combination of a rubber core, a rear cover, a floating member, and a contact unit. By adjusting the contact structure for contacting one of the card boards and adjusting the opening direction of the floating member, it is possible to accommodate card boards at different specific angles to be inserted into the card edge connector. In addition, the gap between the floating member and the rubber core and the rear cover allows the card board to have a floating effect when plugged into its card edge connector. Thus, a customized card edge connector with dual card boards can be designed according to different plug-in situations, thereby increasing the flexibility of the connector, reducing production costs, and improving the efficiency of connector assembly.

[0083] The above embodiments are only used to illustrate the implementation scheme of the utility model and to explain the technical features of the utility model, and are not used to limit the protection scope of the utility model. Any changes or equivalent arrangements that can be easily completed by a person skilled in the art are within the scope claimed by the utility model, and the scope of protection of the utility model shall be subject to the claims.
