Abstract

The utility model relates to a three-way contact piece used in a network plug. The three-way contact piece is T-shaped and comprises a contact part, a connection part extending from the contact part, and a first fixing part, a second fixing part and a third fixing part which are forked from the connection part. The contact part is provided thereon with a positioning hole. A first contact, a second contact and a third contact are formed at the bottom of the first fixing part, the second fixing part and the third fixing part respectively. A first fixed contact and a second fixed contact protrude from the outside surface of the first fixing part. A third contact and a fourth contact protrude from the outside surface of the third fixing part. The included angle between the side edge of the first fixed contact of the first fixing part and the third fixed contact of the third fixing part and the side edge of the connection part is more than 90 degrees. In the utility model, the number of fixed contacts outside the first and the third fixing part respectively is increased to 2, instead of 1 in the prior art; and the included angle between the side edge of the fixed contact and the side edge of the connection part is also increased, that is, more than 90 degrees. As a result, after the contact piece is inserted into the shell of the network plug, the contact piece is fastened inside the shell of the network plug more firmly, thereby ensuring signal transmission.

Again, angle between first, second fixed contact adjacent side on the described first fixed part lateral surface and the angle between the 3rd, the 4th fixed contact adjacent side on the 3rd fixed part lateral surface are greater than 90 °.

In addition, first, second fixed contact on the first fixed part lateral surface described in the utility model and the 3rd, the 4th fixed contact adjacent side on the 3rd fixed part lateral surface are curved.

Have, the end of first, second and third fixed part described in the utility model forms the setting of staggering before and after being of first, second, third connecting terminal respectively again.

Described fixed contact is V-shaped.

First, second fixed contact and the 3rd, the 4th fixed contact on the 3rd fixed part lateral surface on the described first fixed part lateral surface are curved.

When connecting contact insertion Network plug housing, first, second fixed contact on the described first fixed part lateral surface and the 3rd, the 4th fixed contact on the 3rd fixed part lateral surface stretch into the interference part of Network plug housing respectively, and it is loosening that the connection contact firmly is fixed in the Network plug housing.

The beneficial effects of the utility model

The fixed contact that the utility model will connect the contact first and third fixed part outside originally is increased to by each 1 respectively 2, angle between the side of this fixed contact and the side of connecting portion also increases simultaneously---greater than 90 °, make when connecting contact insertion Network plug housing, the the 3rd, the 4th fixed contact on first, second fixed contact on the first fixed part lateral surface and the 3rd fixed part lateral surface is simultaneously against inner walls, strengthened and connected the firmness of contact in the Network plug housing, assurance connection transfer function.
