在本发明中,在未作特别说明的情况下,使用的方位词如“上、下、左、右”通常是指参考附图所示的上、下、左、右;“内、外”是指相对于各部件本身的轮廓的内、外。In the present invention, the orientation words such as "up, down, left, and right" as used generally refer to the upper, lower, left, and right as shown in the accompanying drawings; "inside and outside", unless otherwise specified. It refers to the inside and outside of the contour of each component itself.
如图7中所示,根据本发明一种优选实施方式的接地结构,包括有接地端子1、接地本体2,以及依次穿过接地本体2和接地端子1并与接地端子1螺接的螺钉3。As shown in FIG. 7, a grounding structure according to a preferred embodiment of the present invention includes a grounding terminal 1, a grounding body 2, and a screw 3 that sequentially passes through the grounding body 2 and the grounding terminal 1 and is screwed to the grounding terminal 1. .
其中,螺钉3通常包括抵靠接地本体2的螺帽30以及用于穿过接地本体2且具有外螺纹的螺杆31。从而,由于本发明将接地端子1和螺钉3的螺帽30连接为分别抵靠在接地本体2的两侧,可以省去螺母等部件,并在连接螺钉3的过程中能够利用螺帽30在旋转时与接地本体2之间的摩擦而去除表面涂层,便于提高生产效率、节约材料成本。Among them, the screw 3 generally includes a nut 30 that abuts against the grounding body 2 and a screw 31 that passes through the grounding body 2 and has an external thread. Therefore, since the present invention connects the ground terminal 1 and the nut 30 of the screw 3 to abut against the two sides of the grounding body 2, the nut and the like can be omitted, and the nut 30 can be utilized in the process of connecting the screw 3 The surface coating is removed by friction between the rotating body and the grounding body 2, which is convenient for improving production efficiency and material cost.
如图3至图5中所示,上述的接地端子1可以包括与接地本体2电连接的连接端10,以及连接有地线4的引出端11。连接端10上形成有第一翻边孔102,该第一翻边孔102的自由端背离接地本体2延伸,且第一翻边孔102的内孔壁上可以设置有螺纹101。通常地,接地端子1的连接端10和引出端11具有较小的厚度,以便设置卷绕地线4的结构等。在此情形下,传统结构的接地端子1并不能够如上述地替代螺母与螺钉3连接。本发明通过在接地端子1上设置第一翻边孔102,增强了接地端子1与螺钉3的有效连接,由此能够将接地端子1设置在接地本体2上与螺钉3的螺帽30相对的一侧,以使螺帽30能够直接接触并摩擦接地本体2。As shown in FIGS. 3 to 5, the above-mentioned ground terminal 1 may include a connection end 10 electrically connected to the ground body 2, and a lead end 11 to which the ground line 4 is connected. A first flange hole 102 is formed on the connecting end 10. The free end of the first flange hole 102 extends away from the ground body 2, and the inner hole wall of the first flange hole 102 may be provided with a thread 101. Generally, the connection end 10 and the lead end 11 of the ground terminal 1 have a small thickness in order to provide the structure or the like of the wound ground wire 4. In this case, the ground terminal 1 of the conventional structure cannot be connected to the screw 3 instead of the nut as described above. The present invention enhances the effective connection of the ground terminal 1 and the screw 3 by providing the first flange hole 102 on the ground terminal 1, whereby the ground terminal 1 can be disposed on the ground body 2 opposite to the nut 30 of the screw 3. One side, so that the nut 30 can directly contact and rub the ground body 2.
应当指出的是,螺纹101不局限于预先在第一翻边孔102的内孔壁上攻丝这一种加工形式,也可以通过将螺钉3选为自攻螺钉,由此,在自攻螺钉旋进安装过程中利用螺杆31与第一翻边孔102的内孔壁的相对转动,在第一翻边孔102的内孔壁上形成螺纹101。It should be noted that the thread 101 is not limited to a processing form in which the thread is previously tapped on the inner wall of the first flange hole 102, and the screw 3 can also be selected as a self-tapping screw, whereby the tapping screw During the screwing installation, the relative rotation of the screw 31 and the inner hole wall of the first flange hole 102 is utilized to form a thread 101 on the inner wall of the first flange hole 102.
为便于将螺钉3连接至接地端子1,第一翻边孔102的朝向接地本体2的一端还设置有内倒角104。In order to facilitate the connection of the screw 3 to the grounding terminal 1, an end of the first flanged hole 102 facing the grounding body 2 is further provided with an inner chamfer 104.
连接端10的抵靠接地本体2的一侧上设有凸起100,凸起100的数量不局限于图3至图5中所示的四个,其数量可以是一个或多个,各个凸起100环绕设置于第一翻边孔102的圆周方向,且在环绕第一翻边孔102的方 向自低至高倾斜设置,如此,凸起100的延伸末端形成有抵靠于接地本体2的棱边103。由此,在将接地端子1连接至接地本体2时,该棱边103能够被压缩变形,以产生沿第一翻边孔102轴向的预紧力,防止螺钉3松动。在这种优选实施方式下,可以省去弹簧垫圈,进一步减少接地结构的零件数量。A protrusion 100 is disposed on a side of the connecting end 10 against the grounding body 2, and the number of the protrusions 100 is not limited to four as shown in FIG. 3 to FIG. 5, and the number thereof may be one or more, each convex The circumference of the protrusion 100 is disposed in a circumferential direction of the first flange hole 102, and is inclined from a low to a high direction in a direction surrounding the first flange hole 102. Thus, the extended end of the protrusion 100 is formed with an edge abutting against the ground body 2. Side 103. Thus, when the ground terminal 1 is connected to the ground body 2, the edge 103 can be compression-deformed to generate a pre-tightening force in the axial direction of the first flange hole 102, preventing the screw 3 from loosening. In this preferred embodiment, the spring washer can be omitted, further reducing the number of parts of the ground structure.
并且,作为一种优选地实现形式,凸起100应布置于连接端10的外周边缘。连接端10上设置有第一翻边孔102,将凸起100布置于外周边缘,可以使凸起100布置为具有更大的尺寸,由此能够通过被压缩变形而提供较大弹力,替代弹簧垫圈产生预紧作用。Also, as a preferred form of implementation, the projections 100 should be disposed at the outer peripheral edge of the connecting end 10. The connecting end 10 is provided with a first flange hole 102, and the protrusion 100 is arranged at the outer peripheral edge, so that the protrusion 100 can be arranged to have a larger size, thereby being able to provide a large elastic force by being compressed and deformed instead of the spring. The gasket produces a preload.
优选地,如图6中所示,接地本体2上背向接地端子1设置的一侧设置有第二翻边孔20。结合图6与图7,第二翻边孔20的自由端(此处的自由端理解为第二翻边孔20的凸缘)背离接地端子1的连接位置设置。螺钉3与接地端子1相对旋转过程中能够使得螺帽30的下侧面摩擦第二翻边孔20的凸缘端部,由此去除接地本体2上的绝缘涂层,便于实现接地端子1与接地本体3之间的电连接。Preferably, as shown in FIG. 6, a side of the grounding body 2 disposed away from the grounding terminal 1 is provided with a second flanged hole 20. 6 and 7, the free end of the second flange hole 20 (the free end here is understood to be the flange of the second flange hole 20) is disposed away from the connection position of the ground terminal 1. During the relative rotation of the screw 3 and the grounding terminal 1, the lower side of the nut 30 can be rubbed against the flange end of the second flanged hole 20, thereby removing the insulating coating on the grounding body 2, thereby facilitating the grounding terminal 1 and grounding. Electrical connection between the bodies 3.
接地本体2可以是如镀锌板一类的家用电器的金属外壳,如微波炉的金属外壳,将本实施例描述的接地结构用在家用电器的金属外壳,即可减少金属外壳的接地结构的零部件数量。并且,在转动螺钉3至其与接地端子1上的第一翻边孔102螺接的过程中,螺帽30摩擦第二翻边孔20的上边缘,这个过程类似于金属外壳上的除涂层操作。应当理解的是,尽管在上述说明中主要以接地本体处于连接状态进行描述,但本发明的接地结构可以为未组装的散件状态,只要其各部分能够对应于本发明技术方案限定的各个技术特征,均属于本发明的保护范围。The grounding body 2 may be a metal casing of a household appliance such as a galvanized sheet, such as a metal casing of a microwave oven. The grounding structure described in this embodiment is used in a metal casing of a household appliance, thereby reducing the grounding structure of the metal casing. The number of parts. Moreover, during the screwing of the screw 3 to the first flange hole 102 on the ground terminal 1, the nut 30 rubs against the upper edge of the second flange hole 20, which is similar to the removal of the metal casing. Layer operation. It should be understood that although in the above description, the grounding body is mainly described in a connected state, the grounding structure of the present invention may be in an unassembled component state as long as its parts can correspond to the respective technologies defined by the technical solutions of the present invention. Features are all within the scope of protection of the present invention.
此外,本发明还提供一种家用电器,如微波炉等,该家用电器具有本发明提供的上述接地结构。Further, the present invention provides a home appliance such as a microwave oven or the like having the above-described grounding structure provided by the present invention.
以上结合附图详细描述了本发明的优选实施方式,但是,本发明并不 限于此。在本发明的技术构思范围内,可以对本发明的技术方案进行多种简单变型。但这些简单变型和组合同样应当视为本发明所公开的内容,均属于本发明的保护范围。The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the invention is not limited thereto. Various simple modifications of the technical solution of the present invention can be made within the scope of the technical idea of the present invention. However, these simple variations and combinations are also considered to be the disclosure of the present invention, and are all within the scope of the present invention.
