Description

Electric connector and electric connector combination

The invention relates to a combination of an electrical connector and an electrical connector, in particular to a combination of an electrical connector and an electrical connector with a contact ring.

The US Patent Publication No. US2017/0273355A1 (corresponding to the World Intellectual Property Organization Patent Publication No. WO2017/163212 A1) discloses that a plurality of terminals form a ring shape separated from each other, and a plurality of pogo pins butted with the terminals.

The World Intellectual Property Organization Patent Publication No. WO2018/202730 A1 (corresponding to the Republic of China Patent Publication No. TW201842856 A) discloses that the first connecting portion includes a plurality of terminals arranged in a circle and arranged on the same plane, and is used to connect with the first The second connecting part that is butted with each other includes a plurality of terminals protruding from the plane.

US Patent No. 5,704,792 discloses that a plurality of pogo pins are contacted on a plurality of metal ring terminals that are electrically spaced apart.

In the above-mentioned prior art, a plurality of conductive terminals that are ring-shaped and located on the same plane are all disclosed, but generally the ring-shaped conductive terminals are formed on a substrate using a circuit molding method similar to a printed circuit board, so the thickness is relatively thin. And it is easy to wear, and if the ring-shaped conductive terminal is formed by stamping, the problem of uneven contact ring surface of the ring-shaped conductive terminal is likely to occur. Furthermore, the generally mating connector usually uses a pogo pin. The effective compression stroke required during the application of the pogo pin is relatively large. At the same time, due to the limitation of its internal structure, the head of the pogo pin protrudes out of the butt interface. The distance is several times that of other types of elastic terminals. Therefore, the head of the spring thimble is also prone to buckling or bending due to improper external force.

US Patent No. US5,409,403 discloses that a female connector includes three stepped recesses and three annular plates formed by stamping. The male connector has three stepped protrusions and is integrally molded. The three annular plates on the convex part, the annular plate of the female connector and the annular plate of the male connector are in lateral contact. However, this design tends to cause insufficient effective contact pressure between the annular plate of the female connector and the annular plate of the male connector, resulting in poor contact. Although the above-mentioned annular plate has a concave-convex matching design to increase the effective contact pressure, this concave-convex engagement will increase the force required for insertion and removal, which is not suitable for some devices oriented to facilitate insertion and removal.

Each pin has a coupling part coupled to the coupling surface of the corresponding contact ring, and a tail part. The second insulator is arranged on the first insulator, and the second insulator is filled in the opening to cover the connection between the contact rings and the pins, and the tails of the pins expose the second insulator.

In some embodiments, the opening of the first insulator is formed through the back surface to the mating surface, and the second insulator fills the opening to the mating surface.

In some embodiments, the first insulator further has a plurality of openings formed through the back surface to the mating surface, the contact rings are partially exposed from the openings, and the second insulator is also filled in the The openings of the first insulator are to the butting surface.
