Problems solved by technology

When soldering, you need to find a power source on site, plug in the electric soldering iron for preheating, after the preheating is over, the first person holds one end of the 2M connector in one hand, the electric soldering iron in the other hand, and the second person grabs the soldering iron with one hand. Stabilize the data line, and use the solder in the other hand to cooperate. Due to the small space, it is very easy to accidentally burn the hands of the second person, which has a certain degree of danger; Smelling gas, this gas is inhaled into the lungs by the human body, causing potential harm to the human body
Moreover, due to the small space of the 2M joint, it is easy to weld the copper core of the data line and the joint shell of the 2M data line together during welding, causing a short circuit, and welding quality problems such as virtual welding may occur, and it is not easy to be found
[0004] After the welding of the 2M connector is completed, insert it into the digital adapter and tighten the screws to realize business circulation. However, after running for a period of time, a small number of 2M connectors will loosen and fall off due to poor welding, resulting in a failure of business and an alarm from the optical transceiver.
2M services include administrative telephone, dispatching automation, protection and security control, etc. If the 2M line carries administrative telephone service, the problem is not very big. If the 2M line carries relay protection service, the service is 220kV line differential protection , the line is faulty and needs to be tripped. Since the 2M channel is blocked, the line will not trip. At this time, major power grid accidents such as line burning and transformer damage will occur
The above-mentioned 2M cable head manufacturing process has the following problems: First, the process covers the crimping sleeve on the shielding layer and presses it tightly before welding in step (5). If problems are found before or during welding, adjustments are required. Or re-production, because the crimping sleeve has been crimped and fixed, it will make adjustment or disassembly cumbersome, and the crimping sleeve will be wasted, reducing production efficiency
The second is that the process uses solder to weld the pin and the inner conductor of the cable. Due to the structural limitations of the pin, there are still problems such as easy soldering and disconnection when using solder, and it is not easy to be discovered by the operator.

Embodiment 1

[0046] see figure 1 , a quick-fabricated 2M connector of the present invention includes a signal pin 1, a signal pin plug 2, insulators 301, 302, connectors 401, 402, a fixed tube 4, an active connector 5 and an end cap 6, wherein:

[0047] see figure 2 , the front end 101 of the signal pin 1 is a solid structure, and its head is conical, which is used to connect with the corresponding 2M connector on the digital distribution cabinet, and the tail end 102 is a hollow structure for the insertion of the core of the 2M data cable. The signal pin has a first stepped portion 103 formed protruding from its outer surface, and the first stepped portion cooperates with the insulators 301 and 302 to play a limiting role; the hollow end of the signal pin is provided with an L-shaped opening slot 104, the L-shaped opening slot is used to better fix the signal pin plug;

[0048] see image 3 , the front end of the signal pin plug 2 is inserted into the signal pin, and the tail end 201 ...

Embodiment 2

[0068] see Figure 9 , the 2M joint described in this embodiment is quick to make, and the difference from embodiment 1 is:

[0069] The tail end of the signal pin plug is provided with a chamfered portion 204 .

[0070] The chamfered portion makes the tail end of the signal pin plug slightly wider than the front end, which facilitates the insertion of the core of the 2M data cable and is easier to operate.

Embodiment 3

[0072] see Figure 10 , an improved 2M joint described in this embodiment is different from Embodiment 1:

[0073] The inner surface of the signal pin plug is provided with a solder paste layer 10 .

[0074] The solder paste is soft in texture, and when crimping with a crimping pliers, the crimping is firmer and the contact performance is better. In this way, the fire-baking method can be used to realize the welding and fixing of the 2M data line and the signal pin plug, and in combination with the crimping method, the contact conditions of the signal pin plug and the 2M data line can be further improved, and the tightness can be improved.

Description

technical field [0001] The invention belongs to the technical field of communication equipment, and in particular relates to a fast-fabricated 2M connector and a fabrication method thereof. Background technique [0002] With the development of electric power communication, the communication equipment of the substation is becoming more and more perfect. Among these communication equipment, the digital distribution cabinet plays a crucial role, and only by relying on them can the external transfer of the business be realized. [0003] In the digital configuration, the quality of the 2M connector is related to whether each service can be transmitted normally. The current 2M connectors are all welded. However, the 2M connector provides a very narrow space for welding, and the 2M connector is relatively small, which provides more welding space than an electric soldering iron. The soldering head is not much big, and the solder is not easy to place. If the solder is cut short and p...
