With the increasing depletion of global energy resources, the pace of human search for new alternative energy sources is also accelerating. Solar energy is a renewable resource. Converting solar energy into electric energy can not only save energy, alleviate the shortage of power supply, but also reduce environmental pollution. Therefore, solar photovoltaic technology is attracting more and more public attention and favor. Photovoltaic cells are made of materials that can produce photovoltaic effects, such as silicon, gallium arsenide, indium, copper or other materials, which use photovoltaic effects to convert light energy into electricity. At present, photovoltaic modules composed of several photovoltaic cells are widely used, for example, photovoltaic modules are used to build power generation systems, or as curtain walls or roofs of buildings.

The system operation principle of the utility model is that the short circuit of the photovoltaic module causes the overheating of cables and joints. Before the cables are overheated and ignited, the customized high-temperature thrust device filled with mercury liquid will reflect the super-high temperature. When the designed temperature is exceeded or reached, such as 80-90 degrees Celsius, the mercury liquid volume will be multiplied, and the thrust force of the normal contact spring will be greater than that of the normal contact spring. The force acts on the force bar. When the force of the force bar is higher than the normal spring top contact thrust, the lead plate will be separated, and the internal electrical circuit of the two sections of the male stamen structure will be cut off, so that the current can not be turned on. All the electrical circuits of the 20 photovoltaic modules in this series will be suspended without any current output, so that fire can be prevented. Operating and maintenance personnel can also take the first place. At one time, it was found from the monitoring system and arrived at the specific site to deal with and eliminate the danger.

 In recent years, the development trend of electronic semiconductors continues to pursue miniaturization, high efficiency, low consumption and low cost. Because through Silicon Via (TSV) uses laser to drill holes in wafers or chips, and then fills conductive materials into the holes to form conductive paths, which vertically connect the upper and lower surfaces of the same chip to facilitate the stacking of multiple chips, this technology is called three-dimensional integrated circuit (3D IC) construction technology. Compared with the previous multi-chip packaging, three-dimensional packaging technology can shorten the signal transmission path through stacking of multiple chips, make the signal transmission faster, and reduce the space occupied by the package. These advantages make 3D IC become the technology developed by various semiconductor manufacturers, and also become the key to maintain the competitiveness of the domestic IC manufacturing and sealing industry.

Existing electronic instruments, such as ammeters, often need external connecting wires. If the connecting wires are not fixed, they can easily be pulled out, thus destroying the motherboard and the devices connected with them. In order to fix the connecting wire and prevent it from pulling out, the existing methods are usually as follows: 1. The connecting wire is bound by a pressure plate or a tie-in belt, and then the pressure plate or tie-in belt is fixed on the surface shell with a screw. This method requires additional fixed mechanism, high production cost, installation trouble, and is not suitable for use in a smaller space; 2. Knot the connection lines. The knotting position of this method is not well controlled and the operation is inconvenient. 3. Increase the thread fastening parts, or directly process the thread fastening on the connecting line to become a part with the connecting line. This method has a high production cost. Therefore, it is necessary to develop an electronic instrument with anti-pull-out structure of connecting wires, which can not only increase cost, save space and install conveniently, but also have good anti-pull-out effect

Application field of circular push-pull self-locking connector

Connector is widely used in all fields around us. For people in the electronic market, connector is not unfamiliar. It is a fairly simple function of the widget, but it plays an important bridge in all fields. It is this insignificant component that reflects its particularity, almost in all electronic fields, or It will be used more or less.

Then we will summarize the main products of Shenzhen Jilongtai Connector Co., Ltd. circular push-pull self-locking connectors will be used in what areas:

1. Medical equipment.

Looking around, we can easily find that in some of our country's medical markets, such as medical equipment, beauty equipment clocks, many will use circular push-pull self-locking connectors, both metal and plastic. Medical industry is closely related to our health. Connectors play a very important role in these devices. For example, when the circuit is suddenly blocked, it is easy to cause some very serious accidents. If the connector is used, it is easy to find out the fault point of the line and repair the line immediately. At the same time, the connector also solves the complex wiring problem and facilitates the use of medical staff, which not only improves the efficiency of medical staff, but also further improves the safety of medical equipment.

2. Film and TV equipment.

In the film and television industry, circular push-pull self-locking connector plays a very important role. First of all, our circular push-pull self-locking connector has great advantages in transmitting audio and video signals, with fast transmission speed and low loss. Secondly, the push-pull self-locking structure here also fully reflects its advantages different from other connectors. Push-pull self-locking has been known for its simple and fast insertion method since its inception. It can effectively resist vibration and shock, and effectively prevent the cable from pulling away from the cable. It is absolutely safe and reliable. This easy to plug, easy to pull out and difficult to pull out the security performance, effectively prevent the loss or loss of data of the cameras and projectors that are working during the working period.

3. Testing equipment.

Round push-pull self-locking connectors have been used in nondestructive testers, hardness testers, vibration testers and flow meters.

In addition to the above three aspects, there are aerospace, instrumentation, military equipment and other industries, in which the value of connectors is immeasurable.

In the new trend of development, the rise of new energy has also led to the rapid development of connector industry. Similarly, new energy vehicles, solar street lamps, wind power and so on.

Wire Sealing of Push-pull Self-locking Connector

The conductor seal includes free end push-pull self-locking connector and fixed end push-pull self-locking connector conductor seal. For fluoroplastics wire, in order to make the wire bond firmly, it is necessary to spray sand on the bonding part of the wire to make its surface rough, and then use strong oxidizing agent to corrode the wire. The corrosion process causes the molecule reaction on the wire surface to form a free radical carbon-containing film. The carbon-containing film reacts with the sealing binder to form a real chemical bond.

When welding wires and contacts, the area of solder joints should be small and even with the surface of contacts. On the one hand, the large area of solder joints can avoid destroying the surface coating of contacts, on the other hand, the tip discharge caused by the protrusion or depression of solder joints can be avoided, and the "air pump" can easily be formed by gas adsorption during molding.

It is a circular push-pull self-locking connector for some devices near the frame which need blind connection. It can make the electrical equipment lighter, smaller, easier to maintain and more reliable. This form of connection makes the operator unable to feel the connection. It is necessary to design an accurate positioning device to avoid forcing the incorrectly inserted circular push-pull self-locking connectors together, which makes the incorrect insertion impossible. Cabinet type round push-pull self-locking connector usually adopts floating or elastic contact design structure to ensure its correct connection.

The reflow welding technology is used for electrical connectors. The temperature of this welding technology is higher than that of fluctuating welding, which means that the material of electrical connectors needs to be able to resist significantly higher temperature. Usually, the heating deformation temperature of general materials is higher than 250 C. In order to meet the reflow welding technology, PA6 and PBT can not meet the requirement that the heating deformation temperature of materials is higher than 250 C, so they need to be replaced by high temperature resistant materials. This is the case.

Considering the use of harness environment, harness sheath is needed in extreme environment, such as high temperature, extreme cold, acid-base corrosion, oil pollution and wear.

It can be divided into PVC tube, PU tube, bellows, fiber net, foam tube and so on. The size of the pipe is marked by its diameter. The bigger the diameter, the thicker the pipe.

PVC pipes are widely used, mainly to prevent the wiring harness from spreading, smooth surface, hard in winter, brittle and fragile for a long time, there are openings and closures. Most of the colours are black.

PU pipe, smooth surface, soft material, long service life, there are openings and closures, the color is mostly black.

Fiber network management, the main role is to prevent the harness from spreading, relatively more flexible.

Bellows, mostly coarser wiring harness, oil resistance, acid and alkali resistance, etc.
