Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1, an embodiment of the present application provides an electrical connector terminal set, including: the ground terminal 10, the power terminal 20 and the signal terminal 30 are arranged at intervals, optionally, the ground terminal 10, the power terminal 20 and the signal terminal 30 are arranged at intervals from outside to inside in sequence, and of course, any arrangement of the three terminals is within the protection scope of the present invention.

The number of the signal terminals 30 is two, and the two signal terminals 30 are arranged at the central position of the terminal group at intervals, of course, the positions of the two signal terminals 30 are not limited to the central position of the terminal group, and the signal terminals 30 may be arranged at any position of the terminal group according to design requirements. And the two signal terminals 30 are connected together by a connecting portion 31. The two signal terminals 30 are connected in a lap joint mode through the connecting portion 31, namely the rear ends of the two signal terminals 30 are only needed to be welded with the PCB through a wire by selecting one of the signal terminals 30, so that the number of bonding pads on the PCB is reduced, the production cost is saved, meanwhile, the arrangement distance between the other bonding pads on the PCB is widened, and the short circuit risk caused by too close bonding pads is effectively avoided.

In one embodiment, each of the signal terminals 30 includes a mating portion 32, and the mating portions 32 are disposed in a staggered manner, i.e., the upper and lower surfaces of the tongue plate of the connector are exposed. The connecting portion 31 is integrally connected to the front ends of the two mating portions 32, but the connecting portion 31 is not limited to the front end of the signal terminal 30. The connecting portion 31 is connected to the front ends of the two insertion portions 32, which facilitates the integral forming and processing, and the processing is more convenient.

In one embodiment, the front ends of the two insertion parts 32 extend to form embedded parts 33, one embedded part 33 extends upwards from the front end of the corresponding insertion part 32, the other embedded part 33 extends downwards from the front end of the corresponding insertion part 32, and the front ends of the two embedded parts 33 are located on the same horizontal plane, that is, the two embedded parts 33 are embedded in the tongue plate of the connector; the connecting portion 31 is integrally connected to the front ends of the embedded portions 33, that is, the connecting portion 31 is horizontally and linearly connected between the front ends of the embedded portions 33. Of course, the connection between the connection portion 31 and the two signal terminals 30 is not limited to the horizontal straight line connection, and may be connected in any other arrangement.

In another embodiment, each signal terminal 30 further includes a soldering portion 34 and a main body portion 35, and the soldering portion 34, the main body portion 35 and the insertion portion 32 are integrally connected in sequence. Of course, the connecting portion 31 is connected between the two welding portions 34 or between the two main body portions 35, and the conduction effect is substantially the same as that when the connecting portion 31 is connected between the two insertion portions 32.

In one embodiment, the plug parts 32 are formed by radially reducing the front end of the main body part, which effectively saves materials and saves cost, and meanwhile, because the connection parts 31 are connected among the plug parts 32, even if the width of the plug parts 32 is reduced, the plug terminals can realize data transmission by only contacting one connection part 31.

In one embodiment, the width of the mating part 32 is 0.22-0.28mm, optionally the width of the mating part 32 is 0.25 mm. Compared with the width of the traditional insertion part, the width is reduced by at least half, so that the material is greatly saved, and the cost is saved.

In one embodiment, the insertion portion 32 is formed by bending outward at the front end of the main body portion 35.

In one embodiment, the connecting portion 31 and the signal terminal 30 are made of the same material, i.e., the connecting portion 31 is made of the same metal material as the signal terminal 30. Alternatively, the connecting portion 31 is a conductive member having a different material from the signal terminal 30, for example, a conductive wire, a capacitor, or other members capable of conducting a signal.

The present application further provides an electrical connector comprising: the electric connector terminal group is arranged on the insulating seat.
