Description

Technical Field

[0001] This invention relates to the field of connector technology, and more specifically, to a detachable network module. Background Technology

[0002] like Figure 1 and Figure 2 As shown, traditional network modules are integrated units with non-removable front ends. During use, these modules undergo tens of thousands of insertions and relative movements under axial vibration. The male and female front-end terminals, directly involved in the connection, experience wear. This wear leads to signal transmission loss, potentially causing transmission interruptions and other malfunctions, thus affecting the module's lifespan. Because the front ends of traditional network modules are non-removable, once the terminals wear down, the entire device using the module must be removed and the entire network module replaced. This also requires cutting the cables at the terminal crimping points. Insufficient cable supply may result in unusable cables, leading to inconvenient maintenance and high costs. Summary of the Invention

[0003] The present invention aims to provide a detachable network module to solve the problems of traditional integrated network modules, which require the entire device using the module to be removed and the network module replaced after the terminals wear out.

In this embodiment, the fourth limiting member is a pan head screw 210, and the fastener is a nut 211.

[0103] The structures of the female module rear end 5 and the male module rear end 2 are the same, and will not be described again here. During operation, the female module rear end 5 and the male module rear end 2 are connected to the cable through the cold-pressed holes at their rear ends, and the pins of the male module front end terminal 15 are connected to the sockets of the female module front end terminal 44, forming a circuit.

[0104] For the male module front end 1, both ends of the male module front end terminal 15 are pins. One pin is used to insert into the through hole of the male module rear end terminal 23 in the male module rear end 2, connecting the male module front end 1 and the male module rear end 2. The cold-pressed hole at the other end of the male module rear end terminal 23 is used to connect to the cable.
