Embodiment Construction

[0014] The anti-electromagnetic interference / electromagnetic pulse EMI / EMP socket of the present invention is described in further detail below in conjunction with the above-mentioned accompanying drawings:

[0015] Such as figure 1 As shown, the anti-electromagnetic interference / electromagnetic pulse EMI / EMP socket of the present invention includes a contact piece 1, an interface gasket 2, a base 3, a sealing ring 4, a docking end shell 5, a PCB circuit board 6, a grounding plate 8, and a tail end The housing 9 and the contact piece 1 pass through the corresponding fixing holes of the above-mentioned interface gasket 2, base 3 and sealing ring 4 and are installed in the tail end housing 9 and the butt end housing 5. In order to realize the anti-electromagnetic interference (EMI) function, the socket A low-pass filter 12 is provided in the middle to filter high-frequency interference, and the low-pass filter 12 is a plate capacitor, each contact 1 is welded together with the i...

Abstract

The invention relates to an anti-electromagnetic interference / electromagnetic pulse socket which comprises a contact, an abutting-end casing, an earthing plate, a tail casing, a base, an interface gasket and a sealing ring. The contact passes through the earthing plate, the base, the interface gasket and the sealing ring and is fixed between the abutting-end casing and the tail casing. A transient voltage suppresser is connected between the contact and the earthing plate in parallel through a PCB circuit board; a low-pass filter and an earthing reed are arranged between the tail casing and the contact; in the low-pass filter, an internal electrode is contacted with the contact and an external electrode is contacted with the tail casing through the earthing reed so as to cause that the low-pass filter is electrically connected with the external. The anti-electromagnetic interference / electromagnetic pulse socket is reliable and has the functions of high-frequency conduction interference resistance and transient pulse overvoltage protection.

Description

technical field [0001] The invention relates to an electrical connector socket, in particular to an anti-electromagnetic interference / electromagnetic pulse (EMI / EMP) socket. Background technique [0002] In a complex electromagnetic environment, interference signals can be coupled to the transmission line through various channels, which affects the normal operation of the receiving system, often resulting in the inability to correctly identify the signal received by the receiving system, and in severe cases, causing system malfunction. The strong electromagnetic pulse coupling often damages the electronic components inside the system. Usually, in order to prevent conducted interference from entering the system, corresponding protective measures will be taken, such as installing filters inside the system and installing corresponding protective devices in the circuit. But doing so will make the circuit structure complicated, cost increased, and volume increased. Contents of...
