Description

An improvement of network transmission line connector

This creation involves the improvement of the network transmission line connector. The transmission line connector is mainly an RJ45 connector connector, and the transmission line is mainly a cable with multiple twisted pairs inside (hereinafter referred to as TP cable).

The RJ45 connector is widely used as a communication connector in Ethernet (registered trademark, Ethernet) such as LAN. LAN cable with connector Connect the 8-core 4 groups TP cable to the plug of the RJ45 connector, and plug the RJ45 connector plug into the computer, Web camera, switching hub, wireless LAN access point, IP phone, etc. The socket set by the data equipment for the signal transmission and reception between the communication equipment.

Therefore, as a LAN cable with RJ45 connector, it is gradually being widely used for signal transmission and reception between communication devices. RJ45 connectors and plugs use universal specifications so that they can be easily obtained anywhere in the world. A cable includes 8 8-core signal line, etc. Therefore, LAN cables with RJ45 connectors are most suitable for communication cables.

In addition, in recent years, so-called POE (Power Over Ethernet), which uses this LAN cable to supply direct current to communication signals, has also become popular, and power is supplied to these data devices. POE defines specifications for telex through IEEE802.3af, IEEE802.3at and other specifications.

As shown in Patent Document 1 (Japanese Patent Application Laid-Open No. 2014-235902), the pin of the connector connector is connected to the core wire, and the TP cable is inserted into the connector connector and then riveted and molded. That is, through By riveting the connector connector after inserting the core wire, 8 needles are pressed deeply into the connector connector at the same time, and the sharp front end of each needle penetrates the core wire of the TP cable to make the wire The core wire is crimped with the needle.

However, as in the structure shown in Patent Document 1, when the LAN cable is used as a signal line or a POE telex line, the contact between the cable and the connector joint is likely to cause poor contact.

In recent years, there has been an increase in the demand for LAN cables, especially cables with thin wires of 28 to 32 AWG or higher. In particular, the market demand for using LAN cables as signal cables for communication equipment is expected to be great. However, this kind of thin wire TP cable has the risk of core wire disconnection when riveting the joint.

As shown in Patent Document 2 (CN111630722A), although the plate terminal of the connector and the metal wire of the cable are welded through solder, the connection between the connector and the cable can be made stronger, and the poor connection between the plate terminal and the core wire can be reduced. Problem, but the metal pin is not easy to locate, and the metal pin is easy to lift up during welding.

In addition, when a LAN cable is used as a signal line of a communication device, the use of electronic devices connected to the connector of the LAN cable in a mobile state also frequently increases. Therefore, there is also a problem that the TP cable connector is pulled in a direction away from the connector, which is more likely to be disconnected.

In view of the above shortcomings, the inventor of this case is eager to improve and innovate, and complete this creation "a network transmission line connector and its improvement".

The main purpose of this creation is to provide "an improvement of a network transmission line connector". This connector is located at both ends of the network transmission line. Among them, the connector has:

A set of metal pins, which are arranged in a staggered manner with 4 up and 4 down at the connection end of the core wire;

A rubber core, which is integrated with the metal pin through a buried injection molding method;

A plastic shrapnel, which is provided to prevent the connector from falling off after being inserted into the socket;

A row of wire clamps are used to fix the core wires according to the order of the core wires of the transmission line;

A core wire inner mold rubber core, which is formed between the cable clamp and the outer transmission line, Integrate the transmission line with the cable clamp to facilitate subsequent processing;

A metal shield shell protects the inner core wire from external electromagnetic wave interference and makes the wire data transmission more stable;

A network transmission line with multiple twisted-pair core wires (hereinafter abbreviated as TP cable);

A TP cable connector sheath inner mold rubber core is set to improve the injection molding yield of the cable connector sheath;

A TP cable connector sheath is used to protect the connector and facilitate the plugging and unplugging of the connector.
