Description

V. Description of the invention (J) The technical field to which the invention belongs] The present invention relates to a kind of "card pole card through which the electric == electron Γ refers to a kind of card insertion device with feet. It protrudes early in the row. All of its prior art for circuit board welding] Pressing the 'card plug-in device is used to plug in early electronic products to obtain information exchange between the electronic card and the electronic card. There are many types of electronic cards and small electronic cards, so: Right f: in each category Type specifications, big name: multi-card plug-in device came out. Xi 0 card plug-in devices (and these card plug-in devices must be able to set up a corresponding signal terminal group, 夂 = by this kind of signal terminal The second group of electronic cards is connected by the second type of signal terminal group. == The second type of electronic card must be soldered to Jin 2 and so on by the signal terminal group. Each one is preset by the circuit board. Circuits: Welded and provided with protruding soldering feet (for example: No. contacts and τ are soldered to the electrical :: τ with the soldering pins on each side to form s τ to form a polygonal projection The first knowledge of welding feet; ~ μ production positive knowledge It is single-sided, but multi-style. And two rows of brothers). Xi row highlights its ~ pin (for example: single-sided double row, the first practice of the multi-sided single row, and the script body The flatness of each side, and the sides =, will be difficult to grasp because of the coplanarity between the sides of the valley.

This is a lot of trouble in soldering, and it is easy to cause defective soldering or contact to form defective products. It is even more likely that the soldering surface will pass Π =: the use space of the internal circuit board is reduced, and the area must be increased. Caused by electronic parts or circuits; J Electronics Co., Ltd. did not meet the requirements of light, thin, short and small. The second type of single-sided multi-row welding will not cause much problems, but it is more difficult to miss the welding in the inner row. : 〇 ^ type, the welding feet of the outer row are on it, and the welding feet of the inner row are easy to repair the missing welds of the inner row because of the position, even the current various card insertion devices are fixed type , If there are new specifications of the electronic card, or if you want to change to other combinations (for example, change the two-in-one type of XD, SD and SM to the three-in-one type of XD, SD and CF), Or, if an electronic card has fallen and you want to replace it with another one, you must open another mold to manufacture it separately, which makes it impossible to reduce its manufacturing cost, and it cannot achieve variable application effects, such as "... One electronic product is a three-in-one type suitable for XD, SD, and SM, while the other electronic product is three-in-one type suitable for XD, SD, and CF. The difference is only one of them is the same as the other two. But it ca n’t replace only one of them in manufacturing. ”There are indeed some things that cannot be reduced in cost and cannot be changed. Therefore, the inventor of this case feels that the lack of the above-mentioned prior art still needs to be improved, and has concentrated on research and design, and finally proposes an inventor with a reasonable design and effective elimination of the lack.
