Contact plate fixing structure

接触板固定结构

Abstract

本发明提供一种接触板固定结构,包括躯壳和接触板,躯壳上成型有插槽,插槽在接触板插入一定位置后限制接触板不能继续沿其插入方向前进;接触板上成型有凸台,躯壳在与凸台相对应位置处成型有供凸台插入的弹性卡槽,在接触板插入插槽内一定位置而被插槽限制不能继续前进时,弹性卡槽与凸台形成倒扣锁止结构,以使接触板不能沿与其插入方向相反方向移动,通过倒扣锁止结构和插槽实现了对接触板在其插入方向和插入方向相反方向两个方向的定位,避免了接触板长期使用后因为过盈配合发生蠕变而导致在插入方向的相反方向上出现松动,且倒扣锁扣结构的形成并没有增加新的零部件,不会提高生产成本。
The invention provides a contact plate fixing structure which comprises a body and a contact plate. An inserting groove is formed in the body, and the inserting groove prevents the contact plate from continuing to advance in the inserting direction of the contact plate after the contact plate is inserted into a certain position. A boss is formed on the contact plate, an elastic clamping groove allowing the boss to be inserted into is formed in the position, corresponding to the boss, of the body, when the contact plate is inserted into the certain position of the inserting groove and cannot continue to advance by being limited by the inserting groove, the elastic clamping groove and the boss form an inverted buckling and locking structure so that the contact plate cannot move in the direction opposite to the inserting direction of the contact plate, the contact plate can be located in the inserting direction of the contact plate and in the direction opposite to the inserting direction of the contact plate through the inverted buckling and locking structure and the inserting groove, the situation that the contact plate is crept and is loosened in the direction opposite to the inserting direction due to interference fit after being used for a long time is avoided, the inverted buckling and locking structure is formed and does not need new parts, and production cost cannot be increased.
