电连接器electrical connector

【技术领域】【Technical field】

本实用新型是有关一种电连接器，尤其涉及一种具有接地端子的电连接器。The utility model relates to an electric connector, in particular to an electric connector with a grounding terminal.

【背景技术】【Background technique】

一种常见的电连接器，其可与对接连接器相配合，该电连接器的绝缘本体大致呈长方体状，包括对接部和靠近对接部的收容部。所述收容部跨设有一大致呈门型的接地端子，该接地端子由

状金属冲压形成，包括基部及由基部两端垂直向下延伸的固持部。所述基部一侧设有向前延伸至插接口的弹性接触臂。当对接连接器插入插接口时，弹性接触臂被抬起并与对接连接器相接触。在实际使用中，对接连接器需经常插拔于电连接器，使弹性接触臂被频繁地抬起，又由于接地端子的基部为薄

状，导致基部有被向上抬起的风险。一旦基部不贴合于收容部，弹性接触臂将不能位于正确的连接位置，从而会导致接地端子与对接连接器的接触不良。A common electrical connector, which can be matched with a docking connector, has an insulating body roughly in the shape of a cuboid, including a docking portion and a receiving portion close to the docking portion. A substantially door-shaped grounding terminal is straddled by the receiving portion, and the grounding terminal is formed by

Formed by stamping metal, it includes a base and holding parts extending vertically downward from both ends of the base. One side of the base is provided with an elastic contact arm extending forward to the insertion port. When the butting connector is inserted into the socket, the elastic contact arm is lifted and contacts the butting connector. In actual use, the docking connector needs to be plugged and pulled out of the electrical connector frequently, so that the elastic contact arm is frequently lifted, and because the base of the grounding terminal is thin

shape, causing the base to be at risk of being lifted upwards. Once the base part is not attached to the receiving part, the elastic contact arm will not be in the correct connection position, which will result in poor contact between the ground terminal and the mating connector.

基于上述缺陷，确有必要对现有的电连接器进行改进。Based on the above defects, it is indeed necessary to improve the existing electrical connectors.

【实用新型内容】【Content of utility model】
