FIG. 1 shows a connector subassembly 1 of this application for an embodiment. The connector subassembly 1 includes two interchangeable connectors 10. Among the two interconnecting connectors 10 of the connector subassembly 1, the terminal support component 13 of one connector 10 includes the first surface 131 and the second surface 132 at intervals, and the terminal support component 13 of the other connector 10 includes the first surface 131 and the second surface 132 of the phase back.

As shown in FIG. 2 to FIG. 7, connector 10 is connected to a conductive element 20 outside connector assembly 1 to transmit an electrical signal. The external conducting element 20 may connect to another connector 10.

The connector 10 comprises terminal support component 13, gold finger 14, electric conversion component 15.

Wherein, the gold finger 14 is arranged on the terminal support component 13, the electric conversion component 15 is electrically connected to the gold finger 14. The gold finger 14 is electrically connected to the external conductive element 20 through the electric conversion component 15.

Furthermore, the terminal support component 13 comprises a first surface 131 and a second surface 132, the first surface 131 is opposite to the second surface 132 or the first surface 131 and the second surface 132 are arranged at intervals. A multiple of gold fingers 14 symmetrically arranged on the first surface 131 and the second surface 132. The electric conversion component 15 comprises a main electric unit 151 and two auxiliary conductive units 152. The main electric unit 151 is electrically connected the two auxiliary conductive units 152 and the conductive element 20. The two auxiliary conductive units 152 are electrically connected with gold fingers 14 that respectively arranged on the first surface 131 and the second surface 132 of the terminal support component 13.

Furthermore, the two auxiliary conductive units 152 intersect with the main electrical unit 151 at the same joint 150. The two auxiliary conductive units 152 are non-contacting and insulated with each other in areas other than the joint 150. And, it can be understand, the two auxiliary conductive units 152 are electrically connected to the main electrical unit 151, or the two auxiliary conductive units 152 are extended from the main electrical unit 151. The two auxiliary conductive units 152 are bifurcated within connector 10, and the two auxiliary conductive units 152 are respectively connected to multiple of distant gold fingers 14.

The two connectors 10 cooperate with each other, so that the electrical signals can be transmitted through the symmetrical setting of golden finger 14, avoiding the loss caused by the transmission of electrical signals in short circuit or open circuit, and effectively reducing the attenuation of high-frequency electrical signals in the transmission process.

In one embodiment, two connectors 10 of connector subassembly 1 are provided with joint 150. After the interconnection of connector subassembly 1, all gold fingers 14 are connected (short circuit without connection), so that the attenuation loss of electrical signal in the transmission process is low.

FIG. 8 shows the structure view of an electronic device 10, with 1 dB bandwidth as cut-off frequency. Among them, curves X and Y represent the change curve of electrical signal attenuation when the connector 150 is not set for “bifurcating” in the traditional technology. The cut-off frequency of curve X is 0.4 ghz, and that of curve Y is 0.79 ghz. Curve M represents the change curve of electrical signal attenuation of the electronic device with a pair of joint 150 adopted in this application embodiment. The cutoff frequency of curve M is 1.35 ghz, and the corresponding loss of curve M is lower, with larger bandwidth and better performance. According to the curve M in the figure, connector 10 applied in this paper can effectively reduce the loss of high-frequency electrical signals in the transmission process.
