Problems solved by technology

However, the O-shaped sealing ring protrudes more than the connecting terminal 1. When the connecting terminal 1 is inserted into the accommodation hole, the inner wall of the accommodation hole has a greater friction force on the O-shaped sealing ring, which will cause the O-shaped sealing ring to shift and go out. The groove 2 is squeezed in the narrow gap between the shoulder 3 and the inner wall of the accommodating hole, making it difficult for the connecting terminal 1 to be inserted into the accommodating hole
In severe cases, the excessive extrusion force will crush the O-ring, and the proper sealing effect cannot be achieved.

Abstract

The invention discloses a connection terminal, a tight connection terminal and a connector, and discloses the connection terminal. The connection terminal is characterized by comprising a terminal body, wherein a first containing groove and a second containing groove are distributed in the terminal body along the length direction, respectively surround the terminal body by a circle, and are used for containing a sealing ring; when the sealing ring arranged in the first containing groove is stressed, the sealing ring can move into the second containing groove from the first containing groove and is kept in the second containing groove. The connection terminal disclosed by the invention can guide the sealing rings to move in the process of being inserted into a containing hole by the structure arrangement, the connection terminal can be ensured to be smoothly inserted into the containing hole of a shell, and the O-shaped sealing ring does not step over the corresponding groove to reduce the sealing effect. The sealing ring is guided to move, and can be prevented from being damaged in the process of inserting the connection terminal into the containing hole, and thus the sealing effect is ensured.

Description

technical field [0001] The invention relates to a connection terminal, a sealed connection terminal and a connector. Background technique [0002] Connecting terminals are generally used in connectors for electrical connection with connecting terminals in mating connectors. The terminals are fixed in the housing holes. Such as figure 1 A sealed connection terminal 1 is shown, which is provided with two grooves 2 . An O-ring (not shown in the figure) is arranged in each groove 2 . The two axial sides of each groove 2 are provided with shoulders 3 for restricting the O-ring in the groove 3 . When in use, the connecting terminal 1 is inserted into the housing hole, and the O-ring is used to seal the gap between the connecting terminal 1 and the inner wall of the housing hole. In order to enhance the sealing effect, the O-ring usually protrudes more than the connection terminal 1 . However, before the connecting terminal 1 is inserted into the accommodating hole, the O-rin...
