As shown in
The connector 10 is connected with a conductive element 20 that located outside the connector 10 to transmit an electrical signal, 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. A joint 150 between the two auxiliary conductive units 152 and the main electrical unit 151 to achieve an electrical connection is located inside the connector 10.
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 distance between the joint 150 where the two auxiliary conductive units 152 and the main electrical unit 151 are connected to and the gold fingers 14 is less than 1 cm, furthermore, the distance can be less than 0.75 cm. These values are much smaller than the distance between the connector 150 and the gold finger 14 in the prior art when the connector 150 is located outside the connector 10. Therefore, the connector 10 of this application can effectively shorten the length of empty or open circuit in the circuit.
The two auxiliary conductive units 152 are bifurcated from the main electrical unit 151. The two auxiliary conductive units 152 are connected to two distant gold fingers 14. The above structure is used to meet the double-sided insertion and removal requirements of connector 10. The “bifurcation” joints 150 between the two auxiliary conductive units 152 and the main electrical unit 151 is located inside the connector 10. In traditional structures, “bifurcation” joints 150 are usually located outside the connector 10. The connector 10 in this application can effectively shorten the length of empty circuit or open circuit, so as to effectively reduce the loss of high-frequency electrical signals in the transmission process.
It can be understood that, within the range allowed by the manufacturing process, the smaller the distance between the joint 150 and the gold fingers 14, the smaller the loss of the electrical signal in the transmission process.
Furthermore, the gold fingers 14 are positioned at a first end 136 of the terminal support component 13.

The first terminal group 141 can be arranged on the first surface 131, and the second terminal group 142 can be arranged on the second surface 132. In this embodiment, gold fingers 14 are equally divided into the first terminal group 141 and the second terminal group 142 in the same number. The first terminal group 141 and the second terminal group 142 are set symmetrically. The first terminal group 141 and the second terminal group 142 are symmetrically arranged at the first end 136 of the terminal support component 13. The first terminal group 141 and the second terminal group 142 are used for electrical connection with other conductive elements for transmission of electrical signals.
Furthermore, the electric conversion component 15 is arranged on a second end 137 of the terminal support component 13 opposite to the first end 136. The main electrical unit 151 is arranged on a side of the auxiliary conductive unit 152 away from the gold finger 14. That is, the main electrical unit 151 is electrically connected with the external conductive element 20 to realize the transmission of electrical signals. The main electrical unit 151 “bifurcates” the signal at the joint 150, and electrically connects the “bifurcated” signal with the first terminal group 141 and the second terminal group 142 through the two auxiliary conductive units 152 to realize the transmission of electrical signals.
As shown in
the conductive element 20 is a mother board of a circuit board, the mother board of the circuit board can be an main board of the electronic device or a connection board that is connected to the main board of the electronic device. The electronic device is electrically connected with other transmission units through the connector 10.
The connector 10 further comprises a shell 16. The shell 16 can be an accommodate structure to accommodate with terminal support component 13, gold finger 14 and electrical adapter component 15. The shell 16 comprises at least one first opening 161. The shell 16 wraps with the terminal support component 13. The first end 136 of the terminal support component 13 is extended toward the first opening 161 of the shell 16.
Wherein, the first surface 131 and the second surface 132 are arranged opposite each other. The first surface 13 land the second surface 132 are respectively arranged on two sides of the terminal support component 13.
