CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of Chinese Patent Application No. CN202310967001.2 filed on Aug. 2, 2023, in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.
FIELD OF THE DISCLOSURE
The present disclosure relates to a ground connection member for electrically interconnecting multiple grounding terminals of a connector, and a connector comprising the ground connection member.
BACKGROUND
In the prior art, in order to improve the resonant frequency of the connector, a ground connection member for electrically interconnecting multiple grounding terminals of the connector is usually installed in the connector. Through this ground connection member, the resonant path of the connector can be shortened to increase the resonant frequency. However, in the prior art, the connector has only a single contact point between the ground connection member and each grounding terminal. As a result of this single contact point design scheme, it is difficult to increase the resonant frequency of the connector to a higher resonant frequency.
SUMMARY
According to an embodiment of the present disclosure, a ground connection member adapted to electrically interconnect multiple grounding terminals of a connector includes an installation member, a first contact component, and a second contact component. The installation member has opposite first and second sides in a transverse direction of the ground connection member. The first contact component is assembled onto the first side of the installation member, and includes multiple first elastic arms adapted to electrically contact respective ones of the multiple grounding terminals of the connector. The second contact component is assembled onto the second side of the installation member, and includes multiple second elastic arms adapted to electrically contact respective ones of the multiple grounding terminals of the connector.

As shown in FIGS. 1-3 and 6-8, in an exemplary embodiment of the present disclosure, a ground connection member 3 is disclosed, which is used for electrically interconnecting multiple grounding terminals 2″ of a connector. The ground connection member 3 includes an installation member 30, a first contact component 31, and a second contact component 32. The installation member 30 has a first side and a second side opposite to each other in the transverse direction X of the ground connection member 3. The first contact component 31 is assembled onto the first side of the installation member 30. The second contact component 32 is assembled onto the second side of the installation member 30. The first contact component 31 includes multiple first elastic arms 311, which are used for respectively electrical contact with multiple grounding terminals 2″ of the connector. The second contact 32 includes multiple second elastic arms 321, which are used for respectively electrical contact with multiple grounding terminals 2″ of the connector.
Each grounding terminal 2″ of the connector is in electrical contact with both the first elastic arm 311 and the second elastic arm 321. Therefore, the ground connection member 3 has two contact points with each grounding terminal 2″ of the connector, which can increase the resonant frequency of the connector to a higher resonant frequency. For example, the resonant frequency of the connector can be increased to 21.5 GHz, meeting consumer requirements.
In the illustrated embodiment, the first contact component 31 further comprises a first body 310 and multiple first elastic arms 311. The multiple first elastic arms 311 are connected to the side edge of the first body 310. The second contact component 32 further includes a second body 320 and multiple second elastic arms 321. The multiple second elastic arms 321 are connected to the side edge of the second body 320.

Multiple first holes 312 are formed in the first body 310, and multiple first protrusions 301 are formed on the first side of the installation member 30. The multiple first protrusions 301 are respectively inserted into multiple first holes 312 to assemble the first body 310 onto the first side of the installation member 30. Multiple second holes 322 are formed in the second body 320, and multiple second protrusions 302 are formed on the second side of the installation member 30. Multiple second protrusions 302 are respectively inserted into multiple second holes 322 to assemble the second body 320 onto the second side of the installation member 30.
The installation member 30, the first body 310, and the second body 320 are in a plate shape, and the first body 310 and the second body 320 are perpendicular to the installation member 30. Therefore, in the illustrated embodiment, the cross-section of the ground connection member 3 in its transverse direction X is H-shaped.
The installation member 30, the first contact component 31, and the second contact component 32 may be made of the same or different metal materials. For example, the installation member 30, the first contact component 31, and the second contact component 32 can be made of copper, steel, aluminum, or alloy.
The first body 310 has opposite upper and lower sides in the height direction Z of the ground connection member 3. Multiple first elastic arms 311 are symmetrically distributed on the upper and lower sides of the first body 310. The second body 320 has opposite upper and lower sides in the height direction Z of the ground connection member 3. Multiple second elastic arms 321 are symmetrically distributed on the upper and lower sides of the second body 320.
The first elastic arms 311 on the upper side of the first body 310 are used for respectively electrical contact with the grounding terminals 2″ in the upper row of terminals 2 of the connector. The second elastic arms 321 on the upper side of the second body 320 are used for respectively electrical contact with the grounding terminals 2″ in the upper row of terminals 2 of the connector. The first elastic arms 311 on the lower side of the first body 310 are used for respectively electrical contact with the grounding terminals 2″ in the lower row of terminals 2 of the connector.
