Description

All-in-one Card Connector

technical field

The present invention is related to the connection device of the electronic card, especially refers to a kind of all-in-one card connector which makes the terminals relatively flat by using the embedded molding method and the connection conduction technology.

Background technique

According to the existing card connector, for example, US Pat. No. 6,382,993 discloses that several terminals in the card connector are arranged on the base in an "insert mold" manner.

However, when the fixing method of insert molding is to be applied to the all-in-one card connector, since there are more than two sets of different terminals inside, and the arrangement of the two or more different terminals may be arranged front and back, it is desirable to put this Both groups of terminals are fixed on the base by insert molding, and when the positions where the terminals are embedded in the base and are arranged at the rear, it becomes extremely difficult. For example, a group of terminals located at the front may interfere with terminals at the rear. For another example, the positioning of the two sets of terminals is likely to be interfered or too close to each other during insert molding, making the positioning difficult.

Contents of the invention

The main purpose of the present invention is to provide an all-in-one card connector, which can be embedded into two groups of terminals, which is easier to apply and does not have the problem of difficult positioning or easy interference.

In order to achieve the aforementioned object, an all-in-one card connector provided according to the present invention includes: a base; a cover, which covers the base and forms a card insertion space with the base , the cover and the base jointly form an insertion opening at the front end; a first terminal group is composed of several first terminals, and its partial body is embedded in the base, and the first terminals The front end extends to the card insertion space, and the rear ends of the first terminals are partly exposed outside the rear end of the base; a bridging piece group is composed of a plurality of bridging pieces, and its partial body is embedded in the base The front and rear ends of the bridging pieces are partially exposed on the base, the front ends of the bridging pieces are vertical and planar, and the rear ends of the bridging pieces are located outside the rear end of the base; and a first The two-terminal group is composed of several second terminals, the second terminals are arranged in a terminal frame, the terminals are erected on the base, and the front ends of the second terminals extend to the card insertion space, the The rear ends of the second terminals are partially exposed outside the rear ends of the terminal frame, and the rear ends of the second terminals are also vertical and planar. The planes overlap and touch. For this reason, the two terminal groups can be positioned more easily during insert molding, thereby facilitating manufacturing and saving costs.

Detailed ways

In order to describe the structure and characteristics of the present invention in detail, the following preferred embodiment is given and described as follows in conjunction with the drawings, wherein:

As shown in Figures 1 to 4, an all-in-one card connection 10 provided by a preferred embodiment of the present invention mainly consists of a base 11, a cover 21, a first terminal group 31, and a bridge Group 41, and a second terminal group 51, wherein:

The cover 21 is set on the base 11 to form a card insertion space 12 with the base 11. The cover 21 and the base 11 jointly form an insertion port 14 at the front end for cards. insert.

The first terminal group 31 is composed of several first terminals 32, which are embedded in the base 11 with their partial bodies, and the front ends 321 of the first terminals 32 extend to the card insertion space 12. A rear end 322 of a terminal 32 is partially exposed outside the rear end of the base 11 .

The bridging piece group 41 is composed of several bridging pieces 42, which are embedded in the base 11 with its partial body, and the front ends 421 and rear ends 422 of the bridging pieces 42 are partially exposed on the base 11, and The rear ends 422 of the bridging pieces 42 are located outside the rear end of the base 11 . The rear ends 422 of the bridging pieces 42 are aligned with the rear ends 322 of the first terminals 32 , and some of the bridging pieces 42 and the first terminals 32 are arranged crosswise. Wherein, the front ends 421 of the bridging pieces 42 are vertical and planar, and in this embodiment, the front ends 421 face upward. For the convenience of illustration, the parts of the bridging pieces 42 inside the base 11 are indicated by dotted lines.

The second terminal group 51 is composed of several second terminals 52, the second terminals 52 are arranged in a terminal frame 54, the terminal frame 54 is arranged in the base 11, and the second terminals 52 The front end 521 extends to the card insertion space 12 , and the rear ends 522 of the second terminals 52 are partially exposed outside the rear end 522 of the terminal frame 54 and contact the front ends 421 of the bridges 42 . The rear ends 522 of the second terminals 52 are vertical and planar. The planes overlap and are in contact with each other, and are welded, as shown in the fifth figure. The soldering in this embodiment takes solder (solder) soldering as an example, wherein in FIG. 5 , for the convenience of display, the solder is represented by a ball placed on the top of the bridge piece 42 . In addition, the welding method can also be laser welding, which directly fuses the two materials at the overlap, and is not limited to solder welding.

As can be seen from the above, since the bridging piece set 41 and the first terminal set 31 are both insert-molded on the base 11, the rear ends 422 of the bridging pieces 42 and the first terminals can be formed by insert-molding. The rear end 322 of 32 is flush. After the second terminal group 51 is installed on the base 11 together with the terminal frame 54, the rear ends 522 of the second terminals 52 are in contact with the front ends 421 of the bridging pieces 42, and then welded together. the connection.

In summary, the present invention inserts the bridging piece set 41 and the first terminal set 31 into the base 11, and by welding the second terminal set 51 and the bridging piece set 41, two Terminal sets are easier to locate when insert-molded, making implementation easier. Furthermore, it is easier to manufacture than the prior art, and can save manufacturing cost.
