Problems solved by technology

[0004] But this kind of electrical connector also has the following problems: the ground contact of the electrical connector has little effect on the electric field shielding of the differential pair, especially for the integrity of the differential pair transmission signal between two adjacent rows of differential pairs. It will still be greatly affected, so that the electrical connector can only be used in interconnection systems with low transmission rates. For interconnection systems that need to transmit high-speed data, its application is limited because its signal integrity cannot meet the requirements.

Embodiment Construction

[0034] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] Specific embodiments of the differential connector of the present invention, such as figure 1 , figure 2 As shown, the differential connector includes a housing 1 and a contact assembly 2. The contact assembly 2 includes a ground pin 22 and a signal pin 23. Two adjacent and spaced apart signal pins 23 form a differential pair, and two adjacent There is at least one ground pin 22 between the differential pairs. In this embodiment, the ground pins 22 and the differential pairs are alternately arranged in a linear array, that is, arranged in a "one" shape, and then encapsulated by the insulator 21 . The housing 1 is made of conductive material. In this embodiment, conductive plastic is used. The housing 1 is in direct contact with the insulator 21, but the housing 1 is electrically connected to the ground pin 22 of the contact assembly 2 through th...

Abstract

The invention relates to a differential connector and its housing and contact assembly. The differential connector of the present invention includes a housing, on which there are more than two layers of installation grooves, each layer of installation grooves is inserted with a contact assembly, and the contact assembly includes an insulator and a plurality of linear arrays packaged in the insulator. Differential pairs, there are ground contacts between adjacent differential pairs, and the groove wall of the installation groove is made of conductive material. After the ground contacts and the shell are electrically connected, the shell will become the same low as the ground. potential, thus forming a circle of electric field shielding around the differential pair, which not only reduces the electric field interference of any differential pair from other differential pairs, but also shields the external electric field, which ensures that the differential pair transmits signals Stability and high efficiency, so that the differential connector of the present invention can be used in interconnection systems that need to transmit high-speed data.

Description

technical field [0001] The invention relates to a differential connector and its housing and contact assembly. Background technique [0002] Differential connectors provide signal connections between electronic devices using signal pins. Typically, the signal pins are closely spaced, and crosstalk occurs when one signal pin induces electrical interference in adjacent signal pins due to the mixed electric fields, thereby compromising signal integrity. [0003] The Chinese patent with the authorized announcement number CN203119157U discloses an electrical connector with replaceable contact terminals, including a housing and contact terminals (that is, contacts), and the contact terminals are packaged into terminal blocks (that is, contact components) through insulators. There are at least two rows, and the terminal row is strongly installed in the housing through its insulator. The differential pairs and grounding contacts of the terminal row are arranged alternately, and the...
