The portion A5 and the second contact portion A7 have the effect of electrically connecting.

However, when the position of the socket A1 of the conventional electrical connector A is low, the butt joint B can only insert the side of the electrical component B1 into the insulating body A2 by the socket A1 in the opposite direction to the circuit board C, which will result in A certain height H is formed between the electrical component B1 and the circuit board C, so that the electronic device cannot meet the requirements for thinning.

On the other hand, if the butt joint B is to be disposed with the side of the electric component B1 facing the circuit board C, since the first soldering portion A6 is disposed in the opposite direction of the socket A1, the electrical component B1 and the connector B are likely to be caused. A soldering portion A6 forms a mutual interference phenomenon, which in turn causes a short circuit between the mating member B and the circuit board C, thus further compressing the effective space on the circuit board C.

As shown in the figure, the electrical connector 10 of the present invention is mainly used to electrically connect a connector 20 having an electrical component 21 to a circuit board 30, and includes an insulative housing 40, a plurality of first terminals 50, and a plurality of Second terminal 60.

The insulative housing 40 has a first side 41 formed at the front end and a second side 42 formed on the rear side thereof. The first side 41 is provided with a socket 43 for inserting the connector 20 and parallel with the circuit board 30. The depth of the socket 43 is The first side 41 extends toward the second side 42 , and a plurality of first terminal slots 44 are disposed below the sockets 43 , and a plurality of second terminal slots 45 are disposed above the sockets 43 .

Each of the second terminals 60 is fixed in the insulative housing 40 and includes a second contact portion 61 extending into the socket 43 and a second soldering portion protruding from the outside of the insulative housing 40 for soldering to the circuit board 30. Section 62. The second contact portion 61 is disposed in the second terminal slot 45 of the insulative housing 40 , and a portion of the second contact portion 61 is protruded into the socket 43 for electrically connecting to the mating member 20 . In this embodiment, the second soldering portion 62 is disposed outside the second side 42 of the insulative housing 40 and parallel to the circuit board 30. Of course, in practical applications, the second soldering portion 62 may also be perpendicular to the circuit board 30. In the present embodiment, only the preferred embodiment is described, and the second welded portion 62 is not limited.

Please refer to Figure 4 and Figure 5 for a front view and a partial enlarged view of the creative combination. As shown in the figure, the second terminal slot 45 and the first terminal slot 44 are respectively disposed above and below the socket 43. The first terminal slot 44 and the second terminal slot 45 are staggered with each other, that is, a first terminal. The slot 44 is located at a center position of the two second terminal slots 45, or a second terminal slot 45 is located at a central position of the two first terminal slots 44. When the first terminal 50 and the second terminal 60 are fixed to the inside of the insulative housing 40, each of the first terminal 50 and the second terminal 60 are mutually staggered, and the first terminal 50 and the second terminal 60 are first. Since the contact portion 51 and the second contact portion 61 are partially exposed in the socket 43, the mating members (not shown in the drawings) inserted into the insulating body 40 can be electrically connected to each other.

Please refer to Figure 6 again for a cross-sectional view of the creative combination. As shown, in the present embodiment, the first terminal 50 is inserted and fixed in the insulative housing 40 from the first side 41 of the insulative housing 40, and the second terminal 60 is the second side 42 of the insulative housing 40. The direction is inserted into and fixed to the insulative housing 40 such that the first contact portion 51 of the first terminal 50 and the second contact portion 61 of the second terminal 60 are partially exposed in the socket 43.

It is to be noted that, in this embodiment, the first soldering portion 52 of the first terminal 50 is disposed at the edge of the first side 41 of the insulative housing 40 and perpendicular to the circuit board, and the second terminal The second soldering portion 62 of the 60 is disposed outside the second side 42 of the insulative housing 40 and parallel to the circuit board. Therefore, the center distance D between the first soldering portion 52 and the second soldering portion 62 is greater than the insulative body. The distance D between the first side 41 of the 40 to the center of the insulating body 40 or the center distance D between the first soldering portion 52 and the second soldering portion 62 is greater than the distance between the second side 42 of the insulating body 40 and the center of the insulating body 40.

In addition, since the first soldering portion 51 is disposed perpendicular to the circuit board and is adjacent to the edge of the first side 41 of the insulative housing 40, and does not extend beyond the outer side of the first side 41 of the insulative housing 40, the overall power can be effectively reduced. The depth of the connector 10 further increases the effective utilization space on the aforementioned circuit board.

Please refer to Figure 7 again for a schematic diagram of the cross-section applied to the board. As shown in the figure, when the electrical connector 10 of the present invention is fixed to the circuit board 30, the first soldering portion 52 and the second soldering portion 62 are mainly electrically connected to the circuit board 30 by soldering. However, since the first soldering portion 52 is perpendicular to the circuit board 30 and does not exceed the first of the insulating body 40 The one side 41 can thus leave a large space for the outside of the first side 41 of the insulative housing 40.

Thus, when the docking member 20 is inserted in the direction in which one side of the electrical component 21 is disposed toward the circuit board 30, since the first soldering portion 52 does not extend beyond the first side 41 of the insulative housing 40, The member 20 can be brought closer to the circuit board 30, and the electrical component 21 on the counter member 20 does not cause a short circuit with the first solder portion 52.

Furthermore, the electrical connector 10 of the present invention allows the docking member 20 to be disposed in the direction of the circuit board 30 by using one side of the electrical component 21, so that the height H2 of the docking member 20 will be lower than the height of the electrical connector 10. H1, in this way, the height on the circuit board 30 can be effectively reduced, and as the height H1 of the electrical connector 10 is lower, the effective height on the circuit board 30 also decreases.

Although the technical content of the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and any modifications and refinements made by those skilled in the art without departing from the spirit of the present invention should be covered. In the new category, the scope of protection of this new type is subject to the definition of the scope of the patent application.
