FIELD OF THE INVENTION
[0001] The present invention relates to the technical field of connectors, particularly to one that causes low power loss or no power loss during great voltage and current transmissions.
BACKGROUND OF THE INVENTION
[0002] Conventionally, connectors transmit powers (or electricity) and signals at the same time. With reference to FIG. 1, a connector 1 is connected to a circuit board 2 and includes a housing 3, an adapter plate 5, a first terminal group 7, a second terminal group 9, a third terminal group 11, an adapter seat 13 and a fourth terminal group 15. Among which the third terminal group 11 has a greater area of the electrodes comparing to others' and that is for the purpose of power transmission.
[0003] The connector 1 as shown in FIG. 1 can be further connected to another connecter (not shown), and the second terminal group 9 and the third terminal group 11 have each terminal thereof arranged as a bar without any bending structures; therefore, the adapter seat 13 has to perform the transmission to the circuit board 2 via the fourth terminal group 15. However, the power is transmitted through so many components such as the third terminal group 11, the adapter plate 5, the adapter seat 13 and the fourth terminal group 15, and such transmission will inevitably cause power loss during the process. Also, since the transmission requires the power going through so many components, there is also a possibility that the power value of the voltages and electric currents transmitted by the connector 1 would be limited due to the material characteristics of the components.
[0004] On the other hand, with an assembly by such amount of the components, the structure of the conventional connector 1 has certain thickness that cannot be effectively improved, and this leads to restrictions of applications.
[0005] Therefore, the present invention provides a connector that is able to resolve the deficiencies in the prior art.

Here we have two first engaging sections 1212 for exemplariness; in other embodiments it can be single or multiple. Also, the first engaging sections 1212 are exemplarily arranged as through holes herein.
[0023] In another embodiment, the housing 12 further includes a plurality of third positioning sections 1214 formed on the second surface SF2.

[0026] In another embodiment, the housing 12 further includes a plurality of first positioning elements 128 formed on the first surface SF1 for fixing the housing 12 on the circuit board 2.
[0027] With reference to FIGS. 4(a) - 4(c), there are plan views illustrating the adapter plate 14 mounted on the adapter seat 22 as shown in FIG.2, among which FIG. 4(a) being a front plan view thereof, FIG. 4(b) being a rear plan view thereof, and FIG. 4(c) being a side plan view thereof.
