Plug connector, socket connector and electrical connector assembly thereof

Abstract

The invention relates to a plug connector, a socket connector and an electrical connector assembly thereof. The socket connector comprises a socket housing, a first socket terminal arranged on the socket connector and a pair of second socket terminals opposed to and parallel with the first socket terminal. The first socket terminal is configured to be coupled to a radio frequency signal contact and the second socket terminals are configured to be grounded. The plug connector comprises a support plate, a first plug terminal and a pair of second plug terminals. The first plug terminal is equipped with a first plug connection part arranged on the support plate. Each of the second plug terminals is respectively equipped with a second plug connection part arranged on the support plate. The first plug connection part is configured to be coupled to the first socket terminal and each of the second plug connection parts opposed to the first plug connection part is configured to be coupled to a corresponding second socket terminal.

Description

technical field [0001] The present invention relates to a socket and plug connector combination, and more particularly to a combined socket and plug connector combination configured to couple radio frequency signals. Background technique [0002] Coaxial radio frequency connector assemblies (coaxial radio frequency connector assemblies) are used in conjunction with coaxial cables to enable radio frequency signals to be transmitted under shielding protection. In the prior art, a radio frequency coaxial connector and an electrical connector with a plurality of arranged terminals have been combined in the same housing to form a composite electrical connector. For example, if figure 1 As shown, a composite electrical connection assembly 12 includes a plug connector 13 , a receptacle connector 14 and a pin plug 142 . The plug connector 13 has a pair of coaxial plugs 131 and a pin socket 132 , wherein the pin socket 132 is located between the two coaxial plugs 131 . The socket ...

AI Technical Summary

Problems solved by technology

Generally, the coaxial plug 131 and the coaxial socket 141 have the same predetermined impedance as the cables connected thereto, so their dimensions cannot be easily changed.

[0003] Since the size of the coaxial plug 131 is fixed, it is difficult to further reduce the size of the composite electrical connection assembly 12

Although some methods are used to try to reduce the size, for example like figure 1 As shown, cutouts are made on each coaxial socket 141, however, these thickness reductions are not obvious and still cannot meet the needs of thin electronic devices

Furthermore, inserting the coaxial plug 131 into the coaxial socket 141 requires a high insertion force, which makes the composite electrical connection assembly 12 extremely inconvenient to use.

In addition, the group of the coaxial plug 131 and the coaxial socket 141 and the group of the pin plug 142 and the pin socket 132 are produced using different tools and molds, resulting in high manufacturing cost of the composite electrical connection assembly 12

In addition, the group of the coaxial plug 131 and the coaxial socket 141 and the group of the pin plug 142 and the pin socket 132 need to be assembled in different assembly steps, resulting in complex manufacturing method steps of the composite electrical connection assembly 12.

[0004] In summary, the traditional composite electrical connection with coaxial connectors still has many shortcomings, so it needs to be further improved
