Description

[Technical Field]

[0001] This invention discloses a card edge connector assembly. [Background Technology]

[0002] Existing graphics cards with high-power transmission capabilities have protruding gold fingers due to their high-power card edge connectors, making them incompatible with all system motherboards. A related known technology can be found in Chinese invention patent CN117826942A, which discloses a PCIe adapter board including a connecting module extending from the adapter board body towards the bonding unit and insertable into the bonding unit. This protruding connecting module causes spatial conflicts with other components on the system motherboard, making it incompatible with all system motherboards. Furthermore, the adapter board circuitry fails to provide reliable high-current transmission.

[0003] Therefore, it is necessary to provide an improved card edge connector assembly to solve the above problems. [Summary of the Invention]

[0004] The technical problem to be solved by the present invention is to provide a card edge connector assembly that is compatible with commercially available standard motherboards and ensures reliable high current transmission.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a card edge connector assembly, comprising an electronic card, a first card edge connector, a second card edge connector, and an adapter. The first card edge connector includes a first slot and a first terminal located within the first slot. The second card edge connector includes a second slot and a second terminal located within the second slot. The electronic card has a first gold finger on its left side and a notch on its right side with a second gold finger exposed in the notch. The first gold finger is inserted into the first slot and electrically connected to the first terminal. The second gold finger can be electrically connected to the second terminal through the adapter.

[0006] The present invention also adopts the following technical solution: an adapter, which includes an insulator and a third terminal, the insulator including a base and a tongue plate extending from the base, the base being provided with a third slot, and the third terminal including an elastic arm located in the third slot and a flat plate exposed on the tongue plate.

[0007] Compared with the prior art, the present invention has the following advantages: the second gold finger of the electronic card is located in the notch of the electronic card, thereby avoiding occupying space on the motherboard, so that it can be adapted to commercially available standard motherboards; the adapter uses a high-current terminal with a flat plate to realize the conversion, instead of the existing adapter card, which has high reliability of current transmission and high current resistance.

[0023] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

Specific Embodiments

[0024] Refer Figures 1 to 12As shown in the figure, the present invention discloses a card-edge connector assembly 100, which includes an electronic card 10, a first card-edge connector 20, a second card-edge connector 30, and an adapter 40. The first card-edge connector 20 includes a first slot 21 and first terminals 22 located within the first slot 21. The second card-edge connector 30 includes a second slot 31 and second terminals 32 located within the second slot 31. A first gold finger 11 is provided on the left side of the electronic card 10, and a notch 12 and a second gold finger 13 exposed in the notch 12 are provided on the right side of the electronic card 10. The first gold finger 11 is inserted into the first slot 21 and electrically connected to the first terminals 22, and the second gold finger 13 can be electrically connected to the second terminals 32 through the adapter 40. Both the first card-edge connector 20 and the second card-edge connector 30 can be mounted on a main board (not shown). The second gold finger 13 is provided within the notch 12 of the electronic card 10, and even the second gold finger 13 does not extend downward beyond the lower edge of the notch 12, rather than protruding outward. Thus, it can avoid occupying the space on the main board, and thus can be adapted to commercially available standard main boards. When the paired main board has a high-power card-edge connector (the second card-edge connector 30 in this article), the adapter 40 can be used for the转接 function. In addition, the present invention uses an adapter instead of an adapter board. To a certain extent, the terminals within the adapter are directly used for current transmission at both ends, and the reliability of its current transmission is high, and the current-carrying specification is also relatively high. The above left and right sides only refer to relative positions, and the first, second, and third are only used for differential description and have no sequence.

[0025] Figures 1 to 9 As shown in the figure, for the first embodiment of the present invention, a pair of wings 48 extend from the side of the adapter 40 close to the second gold finger 13, and the wings 48 are fixedly connected to the electronic card 10 by bolts (not shown).

[0026] Refer Figures 1 to 4 As shown in the figure, the adapter 40 includes an insulator 41 and third terminals 42 fixed to the insulator 41. The insulator 41 includes a base portion 411 and a tongue plate portion 412. The base portion 411 is provided with a third slot 413. The third terminals 42 include elastic arms 421 located within the third slot 413 and flat plate portions 422 exposed on the tongue plate portion 412. The second gold finger 13 is inserted into the third slot 413, and the tongue plate portion 412 is inserted into the second slot 31 to achieve electrical connection between the second gold finger 13, the third terminals 42, and the second terminals 32. The third terminals 42 include signal terminals 42S, power supply terminals 42P, and ground terminals 42G arranged in sequence. The power supply terminals 42P and the ground terminals 42G are both in sheet-like structures for large-current transmission. Specifically, refer Figure 3 As shown in the figure, the tongue plate portion 412 includes a first tongue plate portion 4121 and a second tongue plate portion 4122 extending from the base portion 411. The third terminals 42 include signal terminals 42S arranged on the first tongue plate portion 4121 and power supply terminals 42P and ground terminals 42G arranged on the second tongue plate portion 4122. Refer Figure 7 As shown, the elastic arms 421 of the two rows of third terminals 42 are clamped on the second gold fingers 13. At the front end of the flat portion 422 of the signal terminal 42S, there is a bent portion 423 that extends by bending toward the tongue plate portion 412. The bent portion 423 is inserted into the tongue plate portion 412 to fix the signal terminal 42S firmly on the tongue plate portion 412, and the bent portions 423 of the two rows of opposite signal terminals 42S are staggered from each other along the insertion direction of the tongue plate portion 412.

[0027] Refer to Figure 5 As shown, the insulator 41 includes an insulating housing 43 and a terminal module 44 housed in the insulating housing 43. The third terminal 42 is fixed to the terminal module 44, and the insulating housing 43 is fixedly connected to the terminal module 44 by means of a buckle. Specifically, the insulating housing 43 is provided with a pair of holding arms 431, the terminal module 44 is provided with a buckle groove 441, and a convex 442 that is buckled and cooperated with the holding arm 431 is provided in the buckle groove 441.

[0028] Refer to Figure 5 And Figure 6 As shown, a stepped portion 414 is formed on one side of the tongue plate portion 412 of the insulator 41 close to the base portion 411. In this embodiment, the stepped portion 414 and the insulating housing 43 constitute the base portion 411. Additionally, a limiting member 45 is sleeved on the tongue plate portion 412 of the insulator 41. The limiting member 45 presses against the third terminal 42 and makes it adhere to the stepped portion 414, so that the third terminal 42 is fixed between the limiting member 45 and the stepped portion 414. Specifically, the limiting member 45 is a frame opening structure through which the tongue plate portion 412 can pass. The tongue plate portion 412 is provided with a limiting convex portion 415. A receiving space 46 for receiving the limiting member 45 is defined between the limiting convex portion 415 and the stepped portion 414. A guiding inclined surface 416 is provided on one side of the limiting convex portion 415 away from the stepped portion 414 to guide the limiting member 45 to slide into the receiving space 46 and press against the third terminal 42. A bent portion 424 is formed on the third terminal 42 between the limiting member 45 and the stepped portion 414.

[0029] Refer to Figure 8 And Figure 9 As shown, the outside of the insulator 41 is covered with a shielding housing 47. The shielding housing 47 is torn with several metal pieces 471 and is in limiting cooperation with several grooves 417 on the insulator 41. The insulator 41 extends with a pair of wing portions 48. The shielding housing 47 covers the wing portions 48, and thus is installed on the electronic card 10 together with the adapter 40 by bolts. More specifically, a pair of grooves 417 are recessed inwardly on both sides of the insulator 41. The shielding housing 471 is torn with metal pieces 471. The wing-shaped metal pieces 471 are bent toward the grooves 417 and abut against a limiting surface 4171 of the grooves 417, so that the shielding housing 47 is limited and fixed on the insulator 41.

[0030] Refer to Figures 10 to 12As shown, it is the second embodiment card edge connector assembly 100' of the present invention.

[0031] In the second embodiment, the structure of the adapter 40' is basically the same as that of the adapter 40 in the first embodiment. The differences lie in the fixing method of the third terminal 42' and the structure of the insulator 41'. Refer Figure 11 to Figure 12 As shown, a shielding shell 47' is coated on the outer side of the insulator 41'. The shielding shell 47' is fixed to the insulator 41' by bolts. The insulator 41' includes an insulating shell 43' and a terminal module 44' housed in the insulating shell 43'. The third terminal 42' is fixed to the terminal module 44'. The insulating shell 43' is fixedly connected to the terminal module 44' by bolts (not shown). Thus, the shielding shell 47', the insulating shell 43' and the terminal module 44' are fixed together by bolts (not shown).

[0032] Refer Figure 11 to Figure 12 As shown, the insulator 41' includes a base portion 411' and a tongue plate portion 412'. A step portion 414' is formed on one side of the tongue plate portion 412' close to the base portion 411', and a limiting member 45' is sleeved thereon. The base portion 411' is provided with a plurality of fixing columns 418'. The fixing columns 418' pass through the third terminal 42', thereby fixing the conductive terminal 42' to the base portion 411' of the insulator. The tongue plate portion 412' includes a first tongue plate portion 4121' and a second tongue plate portion 4122' extending from the base portion 411'. There is a gap 4123' between the first tongue plate portion 4121' and the second tongue plate portion 4122'. The limiting member 45' is a frame opening structure through which the tongue plate portion 412' can pass. The limiting member 45' slides in the direction of the step portion 414' and finally presses against the third terminal 42'. The third terminal 42' is adhered to the step portion 414', and a bending portion 424' is formed between the limiting member 45' and the step portion 414'. The limiting member 45' is further provided with a plug member 451' penetrating into the gap 4123' to play a role in positioning and fixing.

[0033] In summary, the above is only the preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby. That is, all simple equivalent changes and modifications made according to the claims of the present invention and the content of the specification of the present invention should still fall within the scope covered by the patent of the present invention.
