Description

Ethernet fast plugging electric connector

Technical Field

The invention relates to the field of connectors, in particular to an Ethernet fast plugging electric connector.

Background

With the advent of the information age, the need to transmit or receive signals at any time in life and to obtain reliable and stable signals, there is a need to reduce signal attenuation or electromagnetic interference, which puts increasing demands on electrical connectors. With the trend of miniaturization and high density of the electrical connector, high requirements are put forward on the rapid plugging and unplugging of the electrical connector, the connection between the shell and the cable shield, the sealing between the cable and the shell, and the like. At present, most of electrical connectors for ethernet or signal transmission are threaded electrical connectors, and when a plurality of electrical connectors (on the same panel) are densely arranged, the disadvantage of difficult plugging or locking is particularly prominent; the electric connector and the electric connector are not selected much in forced misoperation prevention; and a modular, cold-welded and detachable high-reversible structure is particularly favored by the market. It is difficult for existing electrical connectors to simultaneously satisfy these demanding conditions. Therefore, it is necessary to design an ethernet fast plugging/unplugging electrical connector with good shielding effect and good sealing performance, which is convenient to operate and has a network transmission rate of ten thousands of megabits.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

As shown in fig. 1, the present embodiment includes two parts, a housing assembly and a contact assembly (or an electrical connector socket composed of the housing assembly and the contact assembly), the housing assembly is arranged with two or more keys, and is mainly used for connection (mechanical connection and electrical connection) and separation with a mating terminal and connection or fixation of each component (module) of the connector itself, so that each part is an integral body. The housing assembly in this embodiment is designed to have a cold-drawing structure, has a function of quick connection, and its specific structure is applied in another application, and its structural composition is not described in detail in this application.

The main parts of the present embodiment are a contact body assembly and a connection structure between the contact body assembly and a housing assembly, and as shown in fig. 2 and 3, the contact body 2 includes three parts, an insulator 2-1 and an insulator 2-3 of a socket body 2-2.

The insulator 2-1 in this embodiment serves mainly to fix the jack 2-2 and to isolate the jack 2-2 from coming into direct contact with the housing assembly 1. Moreover, since the cold-drawn structure is adopted in the present embodiment, the insulator 2-1 plays a guiding role in the housing assembly 1.

In this embodiment, because the signal lines are differential signals, the two signals are a complete signal. Thus for jack 2-2, two jacks are in a group; ethernet signals belong to high-frequency and high-speed transmission signals, so signal lines need to be isolated to avoid interference of signals between different links. Therefore, the isolating bodies 2-3 are arranged between each group of jack bodies, as shown in fig. 3, corresponding clamping grooves are arranged on the insulating bodies 2-1, and the isolating bodies 2-3 are inserted into the insulating bodies 2-1, so that the structure shown in fig. 2 is finally formed.

The isolator in this embodiment also has a shielding function for shielding interference between signal lines, and therefore it is necessary to ground the isolator, while the housing assembly is a natural ground with respect to electrical signals in the connector, so long as good electrical contact between the contact and the housing assembly is ensured. However, in the present embodiment, no matter the housing assembly or the contact assembly is the cold-drawing structure, the contact assembly and the housing assembly have a movement margin therebetween, and the simple contact assembly and the housing assembly cannot ensure the connection in 360 degrees, so that the rigid contact may be broken due to external force.

Therefore, in the embodiment, one or more grounding springs 7 are sleeved on the insulator 2-1, and the grounding springs are formed by winding thin copper wires with high elasticity, so that the high elasticity and the long service life are achieved. As shown in fig. 4, the isolating body 2-3 on the insulator 2-1 is connected with the grounding spring 7 through the external connection position 2-4, and when the shell assembly 1 and the contact body assembly 2 are assembled, the two mutually press the grounding spring 7, so that the shell assembly can be always communicated with the isolating body 2-3 through the grounding spring, and the isolating body is formed by adopting a metal conductive material, thereby ensuring that the isolating body plays a corresponding role and realizing the mutual isolation of the jack bodies.

In the present embodiment, a signal cable is connected to the tail hole of the contact, as described above, because of the high-frequency and high-speed signal transmission of ethernet, a potential difference is generated between the signal cable and the metal housing assembly, so as to generate electromagnetic radiation, which affects the transmission of other signals. Electromagnetic shielding is therefore required for the signal cables disposed within the housing assembly.

In the embodiment, a shielding layer is arranged in the housing assembly at a position corresponding to the signal cable, and the shielding layer is a metal layer sleeved on the signal cable in a loop manner and used for isolating the signal cable from the housing assembly and is connected with a grounding end in the signal cable. In order to ensure that the grounding end in the signal wire is communicated with the external large ground end, looseness between the shielding layer and the shell assembly caused by external force in the reuse process is avoided, and therefore a shielding grounding spring needs to be arranged between the shielding layer and the shell assembly. Can set up the recess along the circumferencial direction at casing subassembly's internal face, also can set up the recess along the circumferencial direction on the outer wall of shielding layer, with shielding ground spring setting in the recess, when shielding layer and casing subassembly equipment, both just can realize the complete contact of shielding layer and casing subassembly through extrusion shielding ground spring.

The invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification and any novel method or process steps or any novel combination of features disclosed.
