Today's commonly used USB interface is widely used in computers, communications, and even home appliances, playing an important interface role. Currently popular USB connector types on the market include general specification A type and MINI B type connectors suitable for USB 2.0 and USB 3.0 versions. In response to connectors of different USB interfaces, receptacle connectors suitable for different protocols have emerged as the times require.

At present, socket connectors suitable for different protocols have two ways to connect the pins to the circuit board: through hole (Through hole) or adhesive (SMT). Both of these methods solder the receptacle connector on the upper or lower surface of the circuit board.

Please refer to FIG. 8 , which discloses an embodiment in which a through-hole socket connector 50 is welded on a circuit board. Holes are punched through the circuit board 70 , followed by soldering to form soldering points on the lower surface of the circuit board 70 .

Another type of adhesive socket connector is to bend the pins protruding from the back of the main body to form a Z shape, and the end of the pins is formed as a flat welding section, which can be directly soldered to the upper surface of the circuit board. Since the pins of the surface-mounted socket connector do not need to pass through the through holes of the circuit board and be soldered on the lower surface of the circuit board, the overall thickness of the through-hole socket connector 50 welded to the circuit board can be slightly reduced; however, for For electronic products that are becoming thinner, thinner and smaller at present, surface mount socket connectors still have limitations in thickness and position. Therefore, at present, the total thickness of the two types of socket connectors after welding with the circuit board cannot be further reduced, which can be further improved for the development of thin, light and small electronic products.

Detailed ways

Please refer to Fig. 1 and Fig. 2, which is a socket connector suitable for different protocols according to the first embodiment of the present invention, which includes an insulating container 1, a first pin group 2a, and a second pin group 2b and a metal shell 3. The present embodiment is aimed at the socket connector of the MINI B type of USB interface.

The insulating container 1 has a body 11 and a tongue 12 . The body includes two opposite first sides and a second side, wherein the tongue plate 12 extends laterally outward from the first side of the body 11, and a notch 15 is formed on the opposite side of the tongue plate 12, and in this In an embodiment, a plurality of parallel elongated grooves 13 are formed on the upper surface of the tongue plate 12 , and a plurality of parallel internal through grooves 14 are formed in the middle of the tongue plate 12 .

Please refer to FIG. 3 and FIG. 4, the first pin group 2a includes a plurality of parallel first pins 21a, and one end of each first pin 21a is disposed on the corresponding elongated groove 13 on the upper surface of the tongue plate 12 , while the other end passes through the notch 15 on the other opposite side of the body 11 of the insulating container 1 .

The second pin group 2b includes a plurality of parallel second pins 21b, one end of each second pin 21b is disposed in the corresponding inner groove 14 of the tongue plate, and the other end comes from the body of the insulating container 1 The notch 15 on the other opposite side of 11 passes through, and is separated from the first pin 21a of the first pin group 2a by a distance, so that a circuit board 4 can be inserted therebetween, and respectively connected with the circuit board 4 on the upper end surface And the corresponding spot welding on the lower end surface. Moreover, since the first and second pin groups 2a, 2b pass through the notch 15, one end of the circuit board can be further inserted into the notch 15 of the body 11, so that the circuit board 4 can be inserted into the notch 15. One end of the first pin group 2a and the second pin group 2b can be clamped in the notch, so that the connection structure between the circuit board 4 and the socket connector will not shake.
