Description

Plug connection, socket connector and its electrical connector combination

The present disclosure relates to a socket and plug connector combination, and more particularly to a composite jack and plug connector assembly that is constructed to couple RF signals.

The coaxial radio frequency connector assemblies are used with coaxial cables to allow RF signals to be transmitted and shielded. Today's technology has combined an RF coaxial connector and an electrical connector having a plurality of terminals arranged in the same housing to form a composite electrical connector. By way of example, as shown in FIG. 1, a composite electrical connection assembly 12 includes a header connector 13, a receptacle connector 14, and a pin header 142. The plug connector 13 has a pair of coaxial plugs 131 and a pin socket 132, wherein the pin sockets 132 are located between the two coaxial plugs 131. The socket connector 14 has a pair of coaxial sockets 141 for receiving the corresponding coaxial plugs 131. A pin plug 142 is located between the pair of coaxial jacks 141. Each of the coaxial sockets 141 may include a pin-shaped male terminal 1411, and each of the coaxial plugs 131 may include a cylindrical female terminal (not shown), and the cylindrical female terminal is configured to receive the male terminal 1411. Generally, each of the cylindrical female terminals is covered by a tubular insulating layer (not shown), which is usually composed of a high dielectric constant material, and the tubular insulating layer is a conductive layer (not drawn) Covered with). Generally, the coaxial plug 131 and the coaxial jack 141 have the same predetermined impedance as the cable connected thereto, so their size cannot be easily changed.

Since the size of the coaxial plug 131 is predetermined, the size of the composite electrical connection assembly 12 is difficult to further reduce. Although some methods have been used to attempt to reduce the size, for example, as shown in Figure 1, slits are made in each of the coaxial sockets 141. However, these thickness reductions are not significant and still fail to meet the needs of thin electronic devices. Furthermore, the insertion of the coaxial plug 131 into the coaxial socket 141 requires a high insertion force, and a high insertion force is required, making the composite electrical connection assembly 12 extremely inconvenient to use. Further, the group of the coaxial plug 131 and the coaxial socket 141 and the set of the pin plug 142 and the pin socket 132 are manufactured using different instruments and molds, resulting in a high manufacturing cost of the composite electrical connection assembly 12. In addition, the set of coaxial plugs 131 and coaxial receptacles 141 and the set of pin plugs 142 and pin receptacles 132 need to be assembled in different assembly steps to create the process steps of the complex composite electrical connection assembly 12.

In summary, the conventional composite electrical connection with a coaxial connector still has many defects, and therefore needs further improvement.
