a connector set 5 disposed on the electronic substrate module 4 and electrically connected to the electronic substrate module, wherein the connector set 5 includes a frame 51 and a plurality of transmission conductors 52 embedded in the frame 51, one end of each transmission conductor 52 is soldered to each soldering portion 42, the other end of each transmission conductor 52 extends toward each receding hole 41 and passes through each receding hole 41 to form a reverse contact portion 521, and a stop portion 511 for limiting the insertion position of a pair of hand connectors is formed on one side of the frame 51.

The tongue portion 44 has a front end transmission conductor contact portion group 441 conforming to USB TYPE C communication protocol, the electronic substrate module 4 has a rear end transmission conductor contact portion group 442 at a position away from the front end transmission conductor contact portion group 441, and the rear end transmission conductor contact portion group 442 and the reverse contact portion 521 conform to USB TYPE a communication protocol.

The total length of the adapter is not greater than 20mm, the length of the tongue portion 44 is not greater than 4.5mm, and the length of the area of the shielding shell 2 not shielded by the insulating resin 1 is not greater than 14.1 mm.

As shown in fig. 1 to 9, the manufacturing process may be performed as follows:

(a) embedding and molding the frame 51 and the transmission conductor 52 of the connector set 5;

(b) mutually welding one end of the transmission conductor 52 and the welding part 42 together, penetrating the reverse contact part 521 at the other end out of the abdicating hole 41, and extending the extending direction of the reverse contact part 521 towards the tongue-shaped part 44, wherein the reverse contact part is in an elastic state (refer to fig. 3 to 5);

(c) the assembled connector group 5 and the electronic substrate module 4 are sleeved into a slot cavity 14 surrounded by the upper support part 12 and the lower support part 13, and each elastic clamping part 43 is positioned in the slot recess 16, but the outermost edge of the elastic clamping part 43 does not contact with the inner side wall of the insulating colloid 1, and in addition, the position of the tongue plate part 44 just corresponds to the position of the slot 11 for inserting the counterpart connector. In addition, at the same time, each of the locking holes 46 and the upper support fixing portion 121 are fixed to each other, and the electronic substrate module 4 is supported by the groove wall of the lower support groove 131 (refer to fig. 4, 4A and 6);

When a user inserts the counterpart connector 6 from the socket 11 and makes a differential motion with the front end transmission conductor contact portion group 441, the counterpart connector can smoothly abut against the tongue portion 44 through the guiding of the guiding rail 45, and when the counterpart connector pushes against the guiding rail limiting portion 451, the counterpart connector is inserted to the deepest position, so that the electrical abutment is completed (refer to fig. 8).

On the other hand, if the counterpart connector 6 is inserted from the direction of the rear end transmission conductor contact portion group 442 and contacts the reverse contact portion 521, it will be stopped by the stop portion 511, and the problem of over-insertion will not occur (refer to fig. 2 and 9).

As shown in fig. 10, there are two elastic latching portions 43a, and the elastic latching portion 43a has a latching conductor portion 431a contacting with the shielding housing 2a, so that the electronic substrate module 4a can form a ground circuit by contacting with the shielding housing 2a through the latching conductor portion 431 a.

As shown in fig. 11, the tongue portion 44b has a tongue portion conductor 443b on each side facing the elastic latching portion 43b, and the tongue portion conductor 443b is designed to avoid poor contact even under a high wear condition of long-term insertion and removal.

Therefore, the technical key of the novel biological electric connector biological switching structure for improving the prior use lies in that:

first, the frame 51 and the transmission conductor 52 are manufactured by insert molding, which effectively improves the production efficiency and increases the manufacturing speed.

Second, the reverse contact 521 extends in a direction away from the rear end transmission conductor contact group 442, which means that when the opposing connector 6 is inserted forward from the rear end transmission conductor contact group 442, the reverse contact 521 is arranged in a special direction, so that it is not easy to generate a collapse problem.

Thirdly, the fastening hole 46 and the upper supporting portion fixing portion 121 are fixed to each other, so that the electronic substrate module 4 is not required to be combined with the insulating colloid 1 by using an adhesive, and the electronic substrate module 4 can be combined with the insulating colloid 1 by using a simple fastening action, and is very stable.

Fourthly, the fastening hole 21 of the shielding case 2 is fastened with the elastic fastening part 43, and the fastening hole 46 and the upper supporting part fixing part 121 are fixed to each other, so that the electronic substrate module 4 is fixed in the left and right directions, thereby providing the fixing advantages of multiple angles and effectively preventing vibration from falling off or breaking.
