A shielded non-magnetic high-density probe array connector

Abstract

The invention relates to a shielded non-magnetic high-density probe array connector, which includes a plug and a socket. The plug includes a probe head assembly, a probe head base, a plug shell and a first fastener. The probe head assembly Set on the base of the probe head, the base of the probe head is connected with the plug shell by screws, the first fastener is sleeved outside the plug shell, and the socket includes a probe base assembly, a probe base base and a socket shell, the probe base assembly is arranged on the base of the probe base, the base of the probe base is connected to the socket shell by screws, the socket shell is provided with a second fastener matching the first fastener, The probe head assembly, plug housing, first fastener, socket housing and screws are all made of non-magnetic material. Compared with the prior art, the invention has the advantages of being able to be used in a strong magnetic environment, having a firm and reliable structure, and the like.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a shielded non-magnetic high-density probe array connector. Background technique [0002] Existing commercial high-density matrix connectors, such as Odu's wire spring connector or ITT's zero insertion force connector, meet the requirements of high current (single contact current greater than 2A) and high density (the number of contacts is greater than 100) and other requirements, but it cannot meet the conditions of non-magnetic and shielding at the same time. For example, the contact gap between the connector will cause electromagnetic leakage, reduce the EMI radiation and anti-interference ability of the equipment; or the physical parts of the connector, in order to obtain high mechanical strength, use stainless steel screws, bearings, etc., which cannot meet the requirements of the magnetic resonance environment. The connector has no magnetic requirements. [0003] Existing high-c...

Problems solved by technology

[0002] Existing commercial high-density matrix connectors, such as Odu's wire spring connector or ITT's zero insertion force connector, meet the requirements of high current (single contact current greater than 2A) and high density (the number of contacts is greater than 100) and other requirements, but it cannot meet the conditions of non-magnetic and shielding at the same time

For example, the contact gap between the connector will cause electromagnetic leakage, reduce the EMI radiation and anti-interference ability of the equipment; or the physical parts of the connector, in order to obtain high mechanical strength, use stainless steel screws, bearings, etc., which cannot meet the requirements of the magnetic resonance environment. Connector non-magnetic requirements

[0003] Existing high-current power connectors require a large contact device in order to achieve high current, which is large in size and difficult to integrate in high density

For connectors with better sealing performance and better shielding, such as medical ultrasonic connectors, the density of contacts is often small, or the current passing through the contacts is small, which cannot meet the requirements for the conduction current of the connector.
