Ground wire clip holder

Abstract

This invention relates to a grounding clamp, which has at least one insertion portion on a grounding electrode. The insertion portion is a frame-shaped hollowed-out area with an inner region. The insertion portion is punched with a pair of elastic arm contact pieces that are bent at more than 90 degrees from the outside to the inside to form a socket. The socket allows the grounding electrode blade of the plug to be inserted, and the outer ends of the pair of elastic arm contact pieces make electrical contact with the grounding electrode blade. Since each elastic arm contact piece has two bent elastic arms, it can generate greater elasticity and bending degree. This invention addresses the problem that previous technologies with outward-bending contact plates that bent less than 90 degrees from the inside out could not meet the new standard of 5000 insertions and removals (the old standard was 2000). The new design, with each contact plate having two bending elastic arms, provides superior insertion and removal pressure. Furthermore, the large elastic range generates a significant amount of wear material, preventing insufficient pressure at the minimum value of 5000 insertions and removals due to reduced wear material. This design allows the contact plate to withstand higher insertion and removal cycles without compromising pressure.

Description

[Technical Field] This invention relates to a grounding clamp, and more particularly to a design in which the longitudinal length of the insertion part is greater than the transverse length, and an elastic arm contact piece with a bend of more than 90 degrees is punched out from the outside to the inside to form a socket. [Previous Technology] As shown in Figure 1, a conventional grounding clamp is formed by a grounding electrode 10 having at least one insertion portion 10a, and the insertion portion 10a is punched into a pair of outwardly bent contact pieces 11 with a bending angle of less than 90 degrees from the inside out. A socket 12 is formed between the inner ends of the pair of contact pieces 11, and the socket 12 allows the grounding electrode blade 30 of the plug to be inserted, and the outer ends of the pair of contact pieces 11 make electrical contact with the grounding electrode blade 30. However, because the width w1 of the insertion portion 10a after punching cannot be too wide (limited by the socket space), and the pair of contact pieces 11 are... The shape of the outward bending and support from the inside to the outside with an angle of less than 90 degrees (the bending axis must be shifted inward relative to the edge), and the limited longitudinal length a1 of the insertion and extraction part 10a, both result in the length of the pair of contact pieces 11 being only half of a1. As a result, the elasticity of the pair of contact pieces 11 is poor. In addition, the insufficient material available for insertion and extraction wear of the pair of contact pieces 11 will lead to wear and deformation and loss of downward pressure. Therefore, the conventionally bent and outwardly supported contact pieces 11 are difficult to meet the new standard of 5000 insertion and extraction cycles (old standard 2000 cycles), and there will be problems of poor insertion and extraction durability and insufficient insertion and extraction wear.

Claims

1. A grounding clamp, which is attached to a grounding plate having at least one plug-in portion, wherein the plug-in portion is a frame-shaped hollowed-out type with an inner region, and the plug-in portion is punched with a pair of elastic arm contact pieces bent at more than 90 degrees from the outside to the inside to form a socket, the socket being for inserting the grounding edge of a plug, and the outer ends of the pair of elastic arm contact pieces making electrical contact with the grounding edge, and since each of the elastic arm contact pieces has two bent elastic arms, a large elastic force and deformation bending degree can be generated.

2. The grounding clamp as described in claim 1, wherein, The outer ends of the elastic arm contact pieces are further formed with outward chamfered edges.

3. The grounding clamp as described in claim 1 or 2, wherein, The longitudinal length of the plug-in part is 1.5 to 4 times the transverse length.
