Detailed Description
The detailed description and technical content of the present utility model are described below with reference to the drawings, which are, however, provided for reference and illustration only and are not intended to limit the present utility model.
As shown in fig. 1, the present utility model provides a vertical card edge connector, which can be disposed on a main circuit board (not shown), and can be used for plugging an electronic card (not shown), such as a memory card, an adapter card, a module card (module card), or a sub-circuit board.
As shown in fig. 1 to 5, the vertical card edge connector (abbreviated as card edge connector) of the present utility model includes: an insulating body 1, a first metal shell 3, a second metal shell 5 and a plurality of terminals T.
The insulating body 1 may be a rectangular elongated body in the present embodiment, but the utility model is not limited thereto. The insulating body 1 has a plugging surface 11, a set of connecting surfaces 12 and a plurality of side surfaces 13 surrounding each other, the plugging surface 11 and the set of connecting surfaces 12 are spaced apart from each other, and the side surfaces 13 are connected between the plugging surface 11 and the set of connecting surfaces 12.
The insulating body 1 further has a card slot 16 and an insulating key 17. The card slot 16 is recessed from the insertion surface 11 of the insulating body 1 toward the assembly surface 12 (hereinafter referred to as insertion direction), and the insulating body 1 has two inner walls 14 corresponding to the card slot 16, and the two inner walls 14 are spaced apart from each other in the width direction of the insulating body 1. The insulating key 17 bridges between the two inner walls 14 within the card slot 16.
The terminals T are provided on the insulating body 1, specifically, on the two inner walls 14 of the card insertion groove 16.
The first metal shell 3 corresponds to the plugging surface 11 and is covered, and the first metal shell 3 is positioned on the plugging surface 11 in various possible manners, for example, as shown in fig. 1, an extending wall (not labeled with a reference numeral) extends along each outer edge of the first metal shell 3 in the plugging direction, and each extending wall is adaptively abutted against each side 13. Wherein, the first metal shell 3 is provided with a slot 31 corresponding to the card slot 16, and two inner side edges 311 opposite to each other at intervals are arranged at the position of the first metal shell 3 corresponding to the slot 31; the first metal shell 3 has a metal beam 32 corresponding to the insulating key 17, the metal beam 32 is bridged between the two inner sides 311 in the slot 31, and the metal beam 32 covers the insulating key 17. It should be noted that the slot 31 and the card slot 16 are connected to each other and communicate with each other.
Therefore, the metal beam 32 is protected on the insulating key 17, so that the metal beam 32 can produce abrasion protection effect on the insulating key 17, has abrasion resistance, and further avoids the damage of the insulating key 17 after the insulating key 17 is plugged in and pulled out by an electronic card for a long time. Further, since the metal beam 32 bridging between the two inner sides 311 of the first metal shell 3 in the width direction is provided, even if the upper half of the electronic card exposed outside the card slot 16 is touched in the width direction carelessly, the lower half of the electronic card inserted in the card slot 16 cannot relatively open the two inner walls 14 in the width direction, because the metal beam 32 (i.e., the reinforcing structure for reinforcement) is provided between the two inner walls 14, the connection between the insulating key 17 and the two inner walls 14 is not damaged or broken, and the effect of structural reinforcement is achieved.
To enhance the abrasion protection effect of the insulating key 17, the metal beam 32 includes a bridging plate 321 and two shielding plates 322, and the two shielding plates 322 are bent and connected to two opposite long sides (not labeled with reference numerals) of the bridging plate 321. The insulating key 17 has a first key surface 171 and two second key surfaces 172, and the two second key surfaces 172 are connected to two opposite long sides (not labeled with reference numerals) of the first key surface 171 in a turning manner. The bridging plate 321 covers the first key surface 171, and each shielding plate 322 covers the second key surface 172, so as to ensure that the insulating key 17 except the exposed first key surface 171 and the two exposed second key surfaces 172 are protected by the metal beam 32, thereby further improving the abrasion protection effect of the insulating key 17. In the metal beam 32, a bridging plate 321 is bridged between the two inner walls 14.
As also shown in fig. 1 to 5, the second metal shell 5 and the aforementioned first metal shell 3 jointly cover the insulating body 1. In detail, the first metal shell 3 and the second metal shell 5 are combined with each other and jointly cover the insulating body 1, and the second metal shell 5 is wrapped corresponding to each side 13 of the insulating body 1. The first metal shell 3 and the second metal shell 5 are combined with each other to form a metal shell S, and the metal shell S is covered outside the insulating body 1, so that the metal shell S also has an effect of shielding interference generated by external abnormal signals (noise) to the insulating body 1 (including the plurality of terminals T).
The second metal shell 5 is also extended with a plurality of metal fillets 51 for direct grounding. In this way, by simply soldering each metal solder leg 51 to the main circuit board (the grounding circuit not shown in the drawing is required to be electrically connected), the metal shell S can be directly grounded, and the external noise can be effectively and rapidly released through grounding. In addition, there is also an effect that the metal shell S is firmly fixed to the main circuit board together with the insulating body 1 covered therewith.
As for the manner of combining the first metal shell 3 and the second metal shell 5, they may be integrally connected to each other to form a metal shell (not shown), or they may be snapped to each other to form the metal shell S as shown in the figures, or any other possible combination manner may be adopted, which is not limited in this aspect of the utility model, and the snap combination with each other is exemplified in the present embodiment.
The first metal shell 3 and the second metal shell 5 are respectively provided with a buckling part structure 33 and a buckling body structure 52, and the buckling part structure 52 is buckled corresponding to the buckling part structure 33 so as to be combined into the metal shell S together.
In detail, the buckling structure 52 includes a plurality of inverted protrusions 521 protruding from the second metal shell 5, and the buckling structure 33 includes a plurality of buckling holes 332 formed in the first metal shell 3, and each inverted protrusion 521 is buckled corresponding to each buckling hole 332.
Wherein, the back-off convex body 521 has a back-off effect; the fastening structure 33 further includes a plurality of lugs 331 integrally bent and extended with respect to two outer edges of the plurality of outer edges of the first metal shell 3, and each lug 331 is provided with a fastening hole 332. The lugs 331 also extend in the plugging direction and can therefore rest against the outer wall (not shown) of the second metal shell 5.
Thereby, the combination between the first metal shell 3 and the second metal shell 5 becomes easier, and the two-piece structure (the first metal shell 3 and the second metal shell 5) can simplify the production and manufacturing flow and reduce the manufacturing cost.
In summary, the upright card edge connector of the present utility model can achieve the expected purpose and solve the drawbacks of the prior art.
The foregoing description is only illustrative of the preferred embodiments of the present utility model and is not to be construed as limiting the scope of the utility model, as all changes which come within the meaning and range of equivalency of the description and drawings are intended to be embraced therein.
