The additional heat dissipating slot 14 extends through the front end surface 12 and the rear end surface of the insulative housing 16, as shown in the sixth and seventh figures, the additional heat dissipation slot 14 penetrates the front end surface 12 of the insulative housing 1 by the slot 140. 月 "See the sixth to tenth figure in the first embodiment, the conductive terminal 3 has a holding portion 32 extending horizontally in the insertion direction, abutting portion 31 bent forward from the holding portion 32, and a connecting portion holding portion 32 extending horizontally rearward from the domain portion 32, respectively, the left and right edges respectively A plurality of barbs 32 are formed. The abutting portion y is inclined downward from the holding portion 32 and then bent upward to form an elastic pressing portion, and then horizontally extending from the end of the elastic pressing portion 310 to form a free end 312 〇 conductive terminal 3 accommodate the Weiyuan body 1 (four), and the thin joint portion 31 is received in the connection 201 230515 The contact portion 32 is received in the holding portion receiving groove 112, and the connecting portion 33 extends beyond the rear end surface 16 of the insulating body 1 for electrical connection with a mother board (not shown). The elastic pressing portion 31 of the abutting portion 31 extends beyond the contact portion receiving groove 110 and enters the central slot 1 . The free end 312 is located in the slot 1HH and is supported by the supporting portion 1〇5. The holding portion 32 is received and held. When the portion is received in the groove 112, the barbs 32 on both sides of the groove are respectively interference-fitted with the side walls of the holding portion receiving groove 112 to hold the conductive terminal 3 in the insulating body. • When the card 200 is inserted into the card edge connector 1 沿 in the plugging direction extending forward and backward, one end of the gold finger 203 is received in the central slot 1 , and is electrically connected to the elastic pressing portion 310 of the conductive terminal 3 . Turning on, forming an electrical connection between the card 2 〇〇 and the card edge connector 1 。. A contact heat source is generated in a region where the gold finger 203 is in contact with the elastic pressing portion 31 (refer to FIGS. 8 to 10, which show how the heat source is transferred from the insulating body 1 to the outside), the gold finger 203 and the conductive terminal 3 In the contact area, the heat source is radiated to the outside by the heat sink 1 (n, the additional heat sink I4 and the slot M0 and the slot 1101) which are in pure 1G connection with the towel center. The gold finger 2〇3 is in contact with the conductive end > The heat source behind the area is conducted to the outside by the additional heat dissipation groove 14 and the heat dissipation through grooves 1121 and 1122 which are in communication with the central slot 1 . In the first embodiment, the additional heat dissipation groove 14 is penetrated through the front and rear end faces η, 16 ' It is also possible to pass only the front end face 12 or the rear end φ 14 only when it penetrates only one of the end faces, and the heat dissipation effect is good. Thus, by the structure of the heat dissipation through grooves 1121 and 1122, it is ensured. The heat source generated after the card 200 and the card edge connector 100 are electrically connected can be timely exported to the card 201230515 edge connector 100 to enhance air convection, thereby reducing the temperature of the insulating body and the gold finger 203 and the conductive terminal 3, thereby improving safety. Please refer to the tenth and twelfth drawings, which are the card edge connector 300 of the second embodiment of the present invention. Compared with the card edge connector 1 of the first embodiment, the card edge The connector 300 is connected to expand the central slot 10 in the upward and downward directions to form a heat dissipation slot 10Γ communicating with the central slot 10, and retains the original size of the central slot at both ends 17. See Figure 12, Central The slot 1 〇 extends into the end π and the rear terminates. A stop portion m is formed to limit the insertion depth of the card 200 for inserting the card 200 into the card edge connector. Therefore, when the card 2 is in the After being placed under the guidance of the central slot 10 of the two end portions 17, the card edge connector is blocked by the broadcast portion 170, and the heat sink (8) located above and below the center slot 1 and the card 2〇0 Between the lower surface, _ is formed between the lower surface, and therefore, the heat source generated after the card 200 and the card edge connector 3 are turned on is discharged along the heat dissipation groove 1〇1, and the eyes are discharged as shown in the thirteenth and fourteenth figures. It is a card edge connector 4A according to the third embodiment of the present invention. The card edge connector 3 of the second embodiment In contrast, the difference is that the opposite longitudinal side wall 1〇3 extends toward the heat dissipation slot ιοί to form a pair of ribs 1〇7, the distance between the pair of ribs 7 and the central slot The heights of 10 are the same, so that the insertion of the card 2 can be performed as a guide. The rear portions of the pair of ribs 107 are also respectively formed with a stopper portion 17〇, which is common with the stopper portion 170 located in the end portion 17. Limiting the insertion depth of the card 2〇〇. Referring to the fifteenth and sixteenth drawings, the card edge connection H according to the fourth embodiment of the present invention is compared with the card edge connector of the second embodiment. The difference is that the longitudinal side wall 1〇3 is integrally recessed upwardly and downwardly to form a heat dissipating groove 1Gi which is connected with the groove ί 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 The distance between each pair of ribs is equal to the original height of the central slot 1〇. Therefore, when the card 200 and the card edge connector 5 (8) are scaled, the card is = in ^ read (9) after the axis is suppressed 7 scale 1 = 3 two: ΓΓ. . A gap as a heat dissipating groove is formed between the central slot 10, and the heat source is radiated outward along the heat dissipating groove 101. It should be particularly pointed out that in the specific embodiment of the present invention, only the card edge = = '' in any practical type of card edge connection" is the principle of the invention. For those of ordinary skill in the art, the equivalent changes made to the present invention under the present invention should still be included in the scope claimed by the scope of the patent application.
