Problems solved by technology

In the current field, it is mainly used in combination with a single injection molded connector, which is troublesome to operate and has poor shielding performance against signal interference. It is inevitable to generate many forms of electromagnetic interference (EMI), which affects the transmission of electronic signals.
However, according to the principle of electromagnetic compatibility, many measures can be taken to reduce electromagnetic interference, control it within a certain range, and ensure the compatibility of electronic equipment or systems, such as putting coaxial cables on ferrite cores, but the cost higher

Embodiment Construction

[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0017] see figure 1 , The combination connector of the present invention includes a zinc alloy shell 10, a plastic fixing piece 40, a film-fixed metal shell 20 and a coaxial cable 30 with a double braided shielding layer. In this embodiment, the total length of the coaxial cable 30 is 10 meters, which effectively suppresses the electromagnetic interference between electronic devices. Compared with the electronic wire, the coaxial cable 30 has a double-layer shielding effect, which is more suitable for those who are concerned about the shielding performance. Use among demanding electronic equipment.

[0018] It is worth mentioning that see figure 2 , the coaxial line 30 includes a plurality of bundles of core wires 35 and an insulating layer 31 ...

Abstract

The invention discloses a combination connector, which comprises a shell, a plastic fixing piece, a film fixing shell and a coaxial cable. The coaxial cable comprises a plurality of core wires and an insulating layer used to wrap the core wires. The invention is characterized in that the shell is a zinc alloy shell. The coaxial cable is fixed on the shell through the plastic fixing piece. A braided shielding layer which wraps the core wires is arranged in the inner layer of the insulating layer. A copper bush is sheathed between the insulating layer and the braided shielding layer. Through the zinc alloy shell and the coaxial cable with the dual-layer braided shielding layer, the invention has the advantages that the shielding effect on signal interference is very good, the electromagnetic interference between electronic devices is effectively suppressed and the shielding effect is improved; in order to reduce signal attenuation, the copper bush is sheathed between the insulating layer and the braided shielding layer to control signal leakage, so better effect is obtained; and the installation is more convenient, the shielding performance is better, the cost is low and the signal attenuation is lower.

Description

technical field [0001] The invention relates to a connector, in particular to a combined connector with a double-layer shielded coaxial cable. Background technique [0002] With the rapid development of modern communication networks and electronic technology, the density of electronic equipment in a limited space is increasing, and mutual interference has attracted more and more attention. The use of shielding measures is to eliminate or suppress electromagnetic interference. effective means. In the current field, injection molded single connectors are mainly used in combination, which is troublesome to operate and has poor shielding performance against signal interference. It is inevitable to generate many forms of electromagnetic interference (EMI), which affects the transmission of electronic signals. However, according to the principle of electromagnetic compatibility, many measures can be taken to reduce electromagnetic interference, control it within a certain range, ...
