The detailed description and technical content of the present invention are described below with reference to the drawings, but the drawings are only for reference and explanation, and are not intended to limit the creation.

Please refer to the first figure and the second figure, which are respectively a partially exploded view and a combined sectional view of the connector socket with a large current identification mechanism. The present invention provides a connector socket 1 having a large current identification mechanism, including an insulating base 10, a plurality of first terminals 20, an identification terminal 30, at least one detecting terminal 40, and a metal casing 50. The first terminal 20 and the detecting terminal 30 are coupled to the insulating base 10 , and the metal housing 50 covers the insulating base 10 to form the connector socket 1 .

The insulating base 10 is a body made of an insulating material. The insulating base 10 includes a base 11 and a tongue 12 extending outward from the front side of the base 11. Furthermore, the first terminals 20 are disposed on one side of the tongue 12 . In an embodiment of the present invention, the first terminals are conductive terminals conforming to the USB 2.0 or USB 3.0 specifications. In actual implementation, it is not limited to this.

The identification terminal 30 is disposed on the base 11. The identification terminal 30 includes a fixing section 31 and a welding section 32 and a contact section 33 respectively extending from the two ends of the fixing section 31. The contact portion 33 is bent and formed into a resilient arm and is positioned on the front side of the base 11. The soldering section 32 protrudes from the bottom surface of the base 11 and is electrically connected to a circuit board (not shown). The fixing section 31 is coupled in the base 11 in a direction in which the parallel insertion is performed.

In the above, the base 11 is a top surface 111 on the side close to the contact portion 33. Preferably, the contact portion 33 is bent toward the top surface 111, and the contact portion 33 is selectively deformed to deform in the direction of the top surface 111. The case where the contact section 33 is abutted is described in detail later.

In the embodiment, the connector socket 1 includes a detecting terminal 40. The detecting terminal 40 is inserted on the base 11 and adjacent to one side of the tongue 12 , and the detecting terminal 40 has a pressing arm 41 protruding from the base 11 . If the connector socket 1 is an all-in-one type of store connector, the detection terminal 40 can be used to detect the type of connector plug inserted.

The metal casing 50 covers the upper and lower sides of the insulating base 10, and a slot 100 is formed on the front side of the base 11.

Please refer to the third and fourth figures, respectively, for the plug-in diagram of the connector socket with the large current identification mechanism and the cross-sectional view after the plugging. The connector socket 1 of the present invention is for plugging a connector plug 2. In use, the connector plug 2 is inserted into the slot 100 of the connector socket 1. The contact section 33 of the identification terminal 30 is selectively compressed to transmit a signal to a circuit board 4.

In more detail, the connector plug 2 has a plug section 3 into which the plug section 3 extends to insert the connector plug 2 on the connector socket 1. Therefore, when the length of the plug section 3 has a certain length, when the plug section 3 is inserted into the slot 100, the contact section 33 is compressed by the plug section 3, and at this time, the contact section 33 can be selected. It is deformed to be deformed in the direction of the top surface 111. On the other hand, when the length of the plug section 3 is short, when the plug section 3 is inserted into the slot 100, the contact section 33 is not compressed by the plug section 3. For example, the connector plug 2 is used to supply a large current, and the length of the plug section 3 has a length to be able to press the contact section 33 when the connector socket 1 is inserted. Accordingly, it is judged whether or not the inserted connector plug is a connector for supplying a large current by whether or not the contact portion 33 is compressed.

Please refer to FIG. 5 again for the other side cross-sectional view of the connector socket of the present invention after being inserted. When the connector plug 2 is inserted into the slot 100 of the connector socket 1, one side of the connector plug 2 is abutted by the pressing arm 41 of the detecting terminal 40, and the inserted device is judged accordingly. Connector plug type 2

Please refer to the sixth and seventh figures, respectively, which are another embodiment of the connector socket with a large current identification mechanism and a cross-sectional view after the plugging. The embodiment is substantially the same as the first embodiment. The connector socket 1a includes an insulating base 10a, a plurality of first terminals 20a, an identification terminal 30a, at least one detecting terminal 40a and a metal housing 50a. The connector socket 1a has a slot 100a, and the insulating base 10a includes a base 11a and a tongue 12a extending outward from the front side of the base 11a. The identification terminal 30a includes a fixing section 31a coupled to the base 11a and a welding section 32a and a contact section 33a extending from the two ends of the fixing section 31a.

This embodiment is different from the first embodiment in that the connector socket 1a further includes a plurality of second terminals 60a. The second terminals 60a are disposed on the other side of the tongue 12a with respect to the first terminals 20a. In an embodiment of the present invention, the first terminals are conductive terminals conforming to the eSATA standard.

When plugged in, a connector plug 2a is inserted into the slot 100a of the connector socket 1. The contact portion 33a of the identification terminal 30a is selectively compressed to transmit a signal to a circuit board 4a.

Please refer to FIG. 8 again, which is another cross-sectional view of another embodiment of the connector socket with a large current identification mechanism. Another difference between this embodiment and the first embodiment is that the connector socket 1a includes a pair of detecting terminals 40a. The pair of detecting terminals 40a have a pair of pressing arms 41a projecting from the base. When a connector plug 2a is inserted into the slot 100a of the connector socket 1a, the pair of pressing arms 41a are pushed against each other by the connector plug 2a to be guided to each other.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the scope of the patents of the present invention. Other equivalent variations of the patent spirit using the present invention are all within the scope of the patent.
