For achieving the above object, the technical scheme that the utility model adopts is:
A kind of center bolt is located little rectangular electric connector plug, comprise plug body 1, the plug screw 4 with snap ring 5 is equipped with in plug body 1 center, many sockets hole 2 and two guide fingers 3 of many row's pins being housed in the plug body 1 at plug screw 4 two ends and being connected with the pin crimping, described guide finger 3 is arranged on long row's two ends.
The material of described plug body 1 is plastics.
A kind of and center bolt is located the suitable socket of little rectangular electric connector plug, comprise jack housing 6, socket screws 9 is equipped with at jack housing 6 centers, have the internal thread hole 10 suitable with plug screw 4 in described socket screws 9 centers, be equipped with in the jack housing 6 at socket screws 9 two ends and many rows pin that spacing during plug body is connected equates and quantity is identical and many sockets pin 7 and two pilot holes 8 that are connected with the pin crimping, the position of described pilot hole 8 is corresponding with the position of guide finger 3.
Be equipped with in the jack housing 6 at socket screws 9 two ends and the many rows pin that spacing equates and quantity is identical during plug body is connected and the many sockets pin 7 that is connected with the pin crimping, the distance of 7 of contact pins is 1mm among the distance between arranging and arranging and the every row.
The material of described jack housing 6 is plastics.
Described contact pin 7 is made inner ring by three stranded plain conductors, and seven stranded plain conductors of elasticity are done the outer ring, and two ends melting welding consists of, inner ring and outer ring reverse stranding, and contact pin 7 middle parts projection, the external diameter of bossing is greater than the internal diameter of jack 2.
The stranded plain conductor of described contact pin 7 inner rings and outer ring is copper cash.
The utility model is compared with existing technology, and has following advantage:
1, after the combination of plug screw and snap ring, peace enters plug body center and plug-assembly combination, and is connected locking with the socket realization, avoids on original plug the screw with fixed cover, since screw in the process screw and fixed cover rub impaired, the problem that causes screw to be deviate from.
2, the distance between contact pin and jack is reduced into 1mm, has realized miniaturization, satisfy widely user's instructions for use.
3, the structure of the utility model contact pin and jack, have that size is little, reliability is high, anti-vibration, shock-resistant, contact resistance is little, contact engaging and separating force is little and the characteristics such as soft.
