I. The basic components of the harness include wires, connectors, external materials and other components.

1.1. Wires

The purpose of the wire is to carry current to transmit signals and provide power. The wire itself contains internal copper wire and external insulation material. Each wire of different specifications has its current value of the allowable load, which is the basis of making a qualified harness. With the increase of automobile function and the general use of electronic control technology, more and more electrical parts and wires are used, and the wire harness becomes thicker and heavier. In the future, to reduce the utilization rate of wires, modern cars have introduced can bus configuration and adopted a multiplex transmission system. Compared with the traditional point-to-point wiring harness, can bus greatly reduces the number of wires and connectors, making the wiring harness lighter and easier.

1.2. Connector and terminal

The terminal and the wire shall be locked in the hole slot of military style electrical connectors after crimping according to the standard, and the male and female connectors shall be butt jointed to meet the connection between the harnesses and the circuit from the harness to the terminal. If they are arranged in the engine compartment with high humidity, according to the requirements of national regulations, waterproof bolts shall be added.

1.3. External parts and other parts

The external parts include corrugated pipe, polyethene pipe, polyethene cloth, sheath, sponge, adhesive tape, harness bracket, etc. to place the abrasion and fracture of wires. Meet the temperature and humidity requirements of different positions of the vehicle body. Generally, corrugated pipe, polyethene pipe, polyethene cloth, hard pipe and sheath are used to prevent the wire from wearing and breaking. Thin wall and thick wall adhesive tapes are used to wrap the wire, and clamps of different shapes are used to fix the wire harness in the proper position of the vehicle body. The purpose of the rubber ring is to prevent the wire harness from scratching when passing through the sheet metal hole.

II. The production wire harness process Because the harness contains many parts mentioned above, the manufacturing process is complex and almost all of them need human intervention. Of course, with the improvement of modern processing technology, more and more automatic devices are applied to the production of the wire harness.

2.1 Tangent line and end pressure

Cut the wire according to the opening size and stripping size required by the drawing, and then use the terminal crimper to crimp the terminal to the wire. Among them, the quality of the terminal crimping is very important. It can be roughly divided into the wrapping requirements of insulating skin and conductor. Only after necessary debugging of crimping machine can the qualified quality of terminal crimping be obtained.

2.2 Subassembly and general assembly

In the past, this process was all manual manufacturing. The wires with crimped terminals were run through pipes, waterproof bolts, military grade electrical connectors, sheaths, tapes and clips. Recently, the new generation of processing equipment can complete most of the above processes, greatly saving labor force and improving production efficiency. To prevent confusion, the manufacturer will provide the drawings shall be transformed according to their conditions, printed on the knotting board to guide the workers to carry out the general assembly, and reasonable process and material distribution shall be carried out to improve the production efficiency and quality.

2.3 Inspection and packaging

In order to ensure the quality of harness, each harness will be inspected for appearance, dimension, continuity and airtightness after manufacturing. Among them, the continuity check is particularly important. The instrument is a customized continuity table (composed of hardware modules and software programs). After connecting the harness connector to the continuity table, start the program to draw a judgment conclusion. Faults such as complete continuity or partial circuit break are easier to pack than other parts. Generally, cartons are used for transportation.

If the harness is a newly developed part, the part test and mainline test shall be carried out. The test of the whole line generally includes the following nine tests: temperature change resistance, high-temperature resistance, low-temperature resistance, damp heat cycle resistance, salt fog resistance, vibration resistance, industrial solvent resistance, voltage drop test and non-delayed combustion performance.

1. Circular Electrical Connector

The MIL-C-38999 standard is an internationally recognized standard with advanced levels. This standard is a general specification for small circular, high density, quick separation, environmental resistance, removable, crimping type electrical connectors.

China has developed and produced this standard product for more than ten years. The main features of GJB599 (equivalent to MIL-C-38999) circular electrical connectors are as follows:

(1) High density

The maximum number of cores is 128. Under the same shell size, the number of signal channels passed by the product is twice that of the series products. Good insulation performance, light weight and small volume. The hole arrangement of MIL-C-38999 is to increase the arrangement of high-density holes on the basis of medium-density product specifications (MIL-C-26482, 83723, etc.). Basically, each shell number has a high-density arrangement. Users can not only use high-density connectors for parts with small volume, but also use medium-density products for power transmission circuits.

(2) Long shell

MIL-C-38999 series I, III, IV are long shells, only series II are short shells. Due to the lengthening of the long shell, the length from the end face of the shell to the end face of the pin increases, which can prevent unplugged plugs and sockets from colliding with foreign objects and damaging the pin during use. It can also prevent blind insertion, wrong insertion or oblique insertion. The connecting ring of the plug touches the bent pin, or it causes a short circuit across the live pin.

Due to the extension of the housing, when the pin plug and the pin socket are mistakenly inserted together, the pin end face of the plug and the pin end face of the socket are at a certain distance, so the pin will not be damaged. In addition, due to the extension of the housing, when military plug connectors and socket are mated, when the pin contacts the end surface of the jack insulator, the plug housing and the socket housing have been engaged for a long length, reducing the inclination of the plug and socket when mated, Improves the alignment accuracy of pin and jack.

The total length of the MIL-C-38999 pin is 27.7% shorter than MIL-C-26482. Because the pins are short, the length of the sealing gasket exposed by the pins is also short, which is beneficial to the ultra-small and fine pins to improve the processing performance, increase the rigidity, and prevent the damage from bending. The jack is a closed-end type, and the sleeve protects the working part of the jack to prevent the jack from damaging the reed and changing the elastic force of the reed during the turnover, packaging or use, which affects its contact performance. The end of the jack sleeve is a trumpet, which can guide the pin into the jack smoothly.

(3) High mix

Various signals and energy transmission lines such as low-frequency, high-frequency, bus, optical fiber and power supply can be mixed in a housing, and the maximum current of a single pin can reach 45 amperes. The transmission signal frequency of MIL-C-38999 series products is one hundred times higher than that of MIL-C-26482 series products.

Therefore, one MIL-C-38999 series plug can replace several MIL-C-26482 series mil spec plug.

(4) High reliability

The locking mechanism of MIL-C-38999 series III products is a three-head threaded quick connection, which can withstand strong vibration and shock, and can automatically lock under strong vibration and shock environments.

MIL-C-38999 product’s connection ring and plug housing fixing method have also been improved. The connection ring of mil c 26482 pin layout series II is fixed to the plug housing by a circlip, which is limited by the circlip snapped into the connection ring groove. Bit.

When the plug seat is inserted, the connecting ring exerts a reaction force on the plug housing through the snap spring, the stop washer, and the corrugated spring. This force always exists as long as it is in working condition. Because the contact surface between the circlip and the circlip groove is limited, the circlip may slip out under stress. If the circlip slides out, it will cause fatal failure of the plug and socket.

MIL-C-38999 series I and II, the connecting ring is limited inward by the corrugated spring and the shoulder of the plug shell, and the outer is limited by the retaining ring stuck on the plug shell.

When the plug and socket are not inserted, the retaining ring acts as a limit. When the plug and socket are inserted, the connecting ring moves inside, there is a gap between the retaining ring and the connecting ring, and the retaining ring does not work. The connecting ring exerts an inward moving force on the plug housing through the corrugated spring to realize plug and socket insertion.

The reaction force of the plug housing on the connecting ring is applied to the connecting ring step through the corrugated spring. Unless the step is damaged, the plug housing will not move out and cause abnormal separation, eliminating potential quality hazards from the design.

Now the price of military plugs connectors is reasonable, anything you need, please contact us.

On the one hand, the number of 5G base stations in China has increased significantly. 5G communication spectrum is mainly distributed in high frequency bands. The higher the frequency, the faster the signal attenuation, and the smaller the coverage area at the same power.

In the 2G, 3G and 4G era, the spectrum of China’s three major operators is mainly distributed below 2.6GHz, and the spectrum of China Unicom and mobile in the 5G stage is in the 3.4-3.6GHz range. With the increase of frequency, the number of 5G base stations will increase significantly and is expected to reach twice the number of 4G base stations.

On the other hand, the demand for 5G also brings the technological upgrade of standard power connectors. Under the characteristics of 5G low-latency and high-bandwidth transmission, the data transmission volume has been greatly improved, and the traffic density of 5G has been increased to 100 times that of 4G. With the miniaturization and integration of 5G base stations, the space occupied by the 5g connector is further increased. Compression, electromagnetic interference and heat dissipation have also become important issues.

Therefore, 5G has higher requirements for the density, transmission rate, heat dissipation, electromagnetic interference resistance and reliability of the connector, and the value of the custom connectors has been further improved.

With the increase in the number of base stations and the increase in technical requirements, the connector market is expected to grow significantly and enter a high-boom cycle.

According to the forecast of the Ministry of Industry and Information Technology of China, domestic operators’ investment in 5G will be 1.5 times that of 4G, and the total investment will reach 1.5 trillion yuan. As for the pace of demand, with the start of 5G construction in 2019, the scale of 5G base station construction will also grow rapidly.

Military connector manufacturers have deep technical accumulation and strong competitiveness, which will fully benefit from the growing demand for connectors in the communications field.
