The specific meaning of the above terms in the present technology can be understood in a specific case to those of ordinary skill in the art.

An injection molded connector, see fig. 1, comprises a circuit board 10, wherein a plurality of terminals 20 formed by electroplating are arranged at the front end of the circuit board 10.

By changing the traditional soldering terminal into the electroplating terminal, the temperature bearable melting point of the electroplated terminal reaches about 600 ℃, and the terminal is firmer when the injection molding process is further carried out.

Referring to fig. 2-3, in order to enable the terminals 20 to be plated on the circuit board 10 accurately and stably, a plurality of ice-drilling grooves 11 are formed in the front end of the circuit board 10, the terminals 20 are located in the ice-drilling grooves 11 and correspond to one another, when the terminals 20 are subjected to plating forming, since the voltage on two sides of the circuit board 10 is high and the voltage in the middle is low, in order to ensure the flatness and the alignment of the whole terminals 20, the current and electron flowing speed of each circuit line is consistent, so that the width and the height of each terminal 20 are kept consistent.

Preferably, in order to make the terminal 20 have better conductivity, the terminal 20 is a copper-plated terminal and is formed in one step, so that the service life of the terminal is longer.

The terminal 20 includes the PIN terminal 21 and the ground terminal 22, the PIN terminal 21 is plural and is arranged at the same distance along the width direction of the circuit board, the ground terminal 22 is located at two side edges of the PIN terminal.

Generally, ten PIN terminals 21 are intercommunicated and conventionally arranged in front of and behind the PIN terminal 21, and certainly, the number of the PIN terminals 21 in the middle can be increased or decreased at will according to requirements, for example, the number is increased to twenty PIN terminals, and the mode of adopting the grounding terminal 22 at the extreme side can enable the grounding wire to have a good grounding condition.

Preferably: the ground terminal 22 is offset from the PIN terminal 21.

In order to further enhance the stability of the whole connector, referring to fig. 1 and 4, the connector further includes an injection molded housing 30, the circuit board 10 is disposed in the housing 30, a notch 31 adapted to the terminal 20 is disposed on the housing 30, and the terminal 20 is inserted into the notch 31.

Because the maximum bearing temperature of the copper-plated terminal can reach about 600 ℃, and the normal injection molding temperature is only 210 ℃, the shell 30 is formed by adopting the injection molding process after electroplating, and the electroplating terminal cannot be influenced.

Two sides of the housing 30 near the notch 31 are respectively provided with a slot 32, and the slots 32 are used for fixing the connector after the connector is inserted into a socket assembly (not shown), so that the connector is more stable.

Preferably: the clamping groove 32 is of an arc-shaped structure, and the arc-shaped structure is more beneficial to plugging and unplugging of a user and has a longer service life compared with an angular structure.

Preferably: the one end of keeping away from notch 31 on the shell 30 is equipped with the fore-set 33 that plays limiting displacement, and the connector needs to peg graft with socket assembly, and fore-set 33 is used for reminding and has inserted the target in place, avoids excessively inserting deeply and damages socket assembly.
