Card edge connector

The present invention relates to a card edge connector, and more particularly to a low profile card edge connector.

A utility model patent No. 201120472638.7 discloses a card edge connector electrically connecting an electronic card to a circuit board, the card edge connector comprising an insulative body disposed longitudinally and a conductive terminal held on the insulative body, the conductive The terminal includes an upper row of terminals and a lower row of terminals, and the lower row of terminals is integrally formed on the insulative body, thereby achieving the effect of reducing the height of the card edge connector. However, since the number of the conductive terminals in the card edge connector is large, when the conductive terminals are soldered to the circuit board, the vertically long insulating body is easily twisted after being heated, so the coplanarity of the soldering portions of the upper row terminal and the lower row terminal is It is difficult to obtain a guarantee, which is not conducive to the soldering of the card edge connector.

Therefore, it is necessary to modify the card edge connector described above.

The purpose of this creation is to provide a card edge connector that facilitates the coplanarity of the weld.

In order to solve the foregoing technical problems, the present invention adopts the following technical solution: a card edge connector comprising a first insulative housing, a first terminal fixed to the first insulative housing, a second insulative housing mounted on the first insulative housing, and The first terminal and the second terminal are respectively disposed on two sides of the electronic card slot and include a convex portion. The first terminal and the second terminal are respectively disposed on the two sides of the electronic card slot. a contact portion is disposed in the electronic card slot, and the electronic card slot is provided with a key button. The two ends of the first insulative housing are respectively provided with a buckle portion, and the two ends of the second insulative housing are corresponding to the buckle portion. The first and second insulative housings are fixed together by a snap relationship between the latching portion and the latching slot.

Compared with the prior art, the present electrical connector has the following functions: since the first and second insulating bodies are fixed together by the snap relationship of the buckle portion and the snap groove, when the first terminal and the second terminal are When the welded portions are not coplanar, the welded portions can be coplanar by adjusting the position of the snap portions in the snap grooves.

Referring to the first and second figures, the present card edge connector 100 mainly includes a first insulative housing 10, a first terminal 30 fixed on the first insulative housing 10, and a second insulation fixed to the first insulative housing 10. The body 20 and the second terminal 40 are fixed on the second insulative housing 20 .

Referring to the second and third figures, the first insulative housing 10 has a first surface 101, and the first surface 101 is recessed downward to form a first receiving area 102, and is formed in the first receiving area 102. The first button portion 103. The first button portion 103 includes a long rib 105 that protrudes upward. The first insulative housing 10 further includes a latching portion 11 on both sides of the first receiving area 102. Each of the latching portions 11 includes a latching arm 107 extending vertically from the first surface 101 to the second insulative housing 20, respectively. And a snap hook 108 extending horizontally from the snap arm 107.

The first terminal 30 includes a contact portion 32 that protrudes rearward from the first housing region 102, a solder portion 33 that extends horizontally forward, and a fixing portion 31 that connects the contact portion 32 and the solder portion 33. The fixing portion 31 is fixed to the first insulative housing 10 , and the soldering portion 33 extends out of the front end surface 1021 of the first insulative housing 10 . The contact portion 32 and the fixing portion 31 are disposed at a small acute angle, so that the first terminal 30 has a smaller size in a direction perpendicular to the first surface 101 (in conjunction with the fourth figure), thereby facilitating the card edge connector. Miniaturization. The contact portion 32 of the first terminal 30 is parallel to the first key portion 103 in the front-rear direction.

The second insulative housing 20 has a second surface 201. The second surface 201 is recessed to form a second receiving area 202 and a second button portion 203 located in the second receiving area 202. The second button portion 203 is second. The surface 201 is recessed with a key groove 205. The long ribs 105 are disposed in the key groove 205 to limit the second insulating body 20 to the left and right on the first insulating body 10. The end faces 22 of the second insulative housing 20 are further recessed with a snap groove 21 extending through the second surface 201. The latching slot 21 includes a first latching slot 207 for receiving the latching arm 107 and a second latching slot 208 for receiving the latching hook 108 . The hooking hooks 108 are received in the second latching slots 208 through the first latching slots 207 . In the vertical direction, the height of the second snap groove 208 is greater than the height of the snap hook 108.

The second terminal 40 includes a contact portion 42 that protrudes forward from the second housing portion 202, a solder portion 43 that extends rearward, and a fixing portion 41 that connects the contact portion 42 and the solder portion 43. The fixing portion 41 is fixed to the second insulative housing 20, and the soldering portion 43 extends from the rear end surface (not labeled) of the second insulative housing 20. The contact portion 42 of the second terminal 40 is parallel to the second key portion 203 in the front-rear direction.

Referring to the first figure, the first insulative housing 10 and the second insulative housing 20 are coupled together by the latching portion 11 and the latching slot 21 . At this time, the long rib 105 of the first button portion 103 cooperates with the key groove 205 of the second button portion 203 so that the first button portion 103 and the second button portion 203 together form the button portion 106, the first receiving portion The area 102 and the second receiving area 202 together form an electronic card slot 109. The button portion 106 is located in the electronic card slot 109. The contact portion 32 of the first terminal 30 and the contact portion 42 of the second terminal 40 are respectively located on both sides of the electronic card slot 109, and are offset by a certain distance in the front-rear direction (refer to FIG. 4).

During the welding process, when the welded portion 33 of the first terminal 30 and the welded portion 43 of the second terminal 40 are distorted by the heat of the insulating body during the welding process, the welded portions 33 and 43 may have a problem of coplanarity. At this time, since the height of the second snap groove 208 is greater than the height of the hook hook 108, the hook hook 108 can be slightly adjusted in the vertical direction in the second snap groove 208, thereby making the first The coplanarity between the welded portion 33 of the terminal 30 and the welded portion 43 of the second terminal 40 is adjusted to facilitate soldering.

In summary, the creation complies with the new patent requirements, so the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and those who are familiar with the skill of the present invention are equivalent to the equivalent modifications or changes made by the spirit of the present creation.
