In order to achieve the above object, the technical solution adopted in the utility model is:

A precision connector with reliable connection, comprising a plastic body and a terminal plugged into the plastic body, the terminal includes a hollow square column body and pins arranged at the lower end of the hollow square column body, the hollow square column The shaped body includes four side walls, one of which is provided with a through hole, and an elastic piece extends downward from the middle of the top wall of the through hole, and the elastic piece includes a hollow square column body that extends downward from the middle of the top wall of the through hole. The first part extending from the inside, the second part extending from the lower end of the first part to the outside of the hollow square column body, the side wall opposite to the side wall is symmetrically provided with through holes and shrapnel, and the two shrapnels together form a trumpet shape In the elastic clamping part, the other side wall of the hollow square column body is provided with an opening, and an elastic card extends downward from the top wall of the opening and toward the outside of the hollow square column body. Correspondingly, the plastic The main body is provided with a card hole, and the elastic card is locked in the card hole.

The pins are arranged on the lower end of one side wall of the hollow square column body, and the pins are arranged on the same side as the elastic card.

The beneficial effects of the utility model are: the engagement of the elastic card on the terminal with the card hole of the plastic body makes

The connection between the terminal and the plastic body is more stable and reliable; the four side walls, shrapnel and elastic card of the hollow square column body of the terminal form a tightly integrated square structure, so that the external connector is always connected with the speaker in the fully enclosed square structure. The shape of the elastic clamping part is in contact with conduction, so that the connection between the external connector and the terminal is more reliable. In this way, the poor contact of the connection is reduced as a whole, and the reliability of the connection is greatly improved.
