Abstract

The present invention relates to a ground clamp, which has at least one insertion and removal portion on a ground piece, and the insertion and extraction portion is a frame-shaped hollow type in which the inner region is hollowed out, and the insertion and extraction portion is punched out from the outward direction. One end of the elastic arm contact piece and more than 90 degrees, and forming a jack, the jack can be inserted into the ground pole of the plug, and the outer end of the pair of elastic arm contacts the pole of the ground Sexual contact, and because each of the elastic arm contact pieces has two bent elastic arms, the cymbal can generate a large elastic force and deformation bending. Therefore, the contact piece for solving the prior art bending from the inside to the outside by less than 90 degrees is difficult to reach the new standard of 5,000 insertions (the old standard 2000 times), and the present invention is contacted by the elastic arms. Each piece has two bent elastic arms, which have better insertion and extraction pressing force, and can generate a very large amount of wearing material due to the large angle elastic range, and will not be inserted and removed 5000 times after the maximum value of the cutting edge. The reduction of the wear material causes the underpressure to be insufficient when the pole is inserted and removed at the minimum, and has the effect of being able to withstand higher insertion times without changing the downforce.

Description

Ground clamp

The present invention relates to a ground clamp, in particular to a designer that allows the longitudinal length of the insertion portion to be greater than the lateral length and punches out the elastic arm contact piece bent more than 90 degrees from the outside to the inside and forms a socket.

As shown in FIG. 1 , the conventional ground clamp is attached to a pole piece 10 having at least one insertion portion 10a, and the insertion portion 10a is punched out from the inside to the outside by less than 90 degrees. One of the outer contact type contact pieces 11 and the inner end of the pair of contact pieces 11 form an insertion hole 12 for inserting the ground insertion blade 30 of the plug, and by the pair of contact pieces 11 The outer end is in electrical contact with the ground insertion blade 30; however, the width w1 after the insertion and removal of the insertion portion 10a cannot be too wide (limited to the socket space), and the pair of contact pieces 11 are inwardly oriented The externally bent outer support and less than 90 degrees (the bending axis must be moved inward relative to the edge), and the longitudinal length a1 of the insertion portion 10a is limited, and the double pair causes the pair of contact pieces 11 to have a length of only half of a1 Therefore, the elasticity of the pair of contact pieces 11 is not good, and because the insufficient material for the pair of contact pieces 11 can be worn and deformed, the deformation is lost and the downforce is lost. Therefore, it is difficult to bend the contact piece 11 of the outer support type. Achieving the new standard of 5,000 insertions (2000 times of the old standard), there will be problems of being unplugged and insufficiently inserted and removed.

The main purpose of the present invention is to solve the problem that the prior art is not resistant to insertion and removal and the amount of insertion and removal is insufficient, and has the effect of being able to withstand higher insertion times without changing the downforce.

Another purpose of the novel is to have the function of two-way insertion and removal.

In order to achieve the above-mentioned effects, the structural feature of the present invention is that a pole piece has at least one insertion and removal portion, and the insertion and extraction portion is a frame-shaped hollow type in which the inner region is hollowed out, and is punched out at the insertion and extraction portion. Bending one of the elastic arm contact pieces from the outside to the inside by more than 90 degrees and forming a socket, the jack is inserted into the ground pole of the plug, and the outer end of the elastic arm is inserted into the pole and the ground is inserted The blade is in electrical contact, and each of the elastic arm contact pieces has two bent elastic arms, so that a large elastic force and deformation bending degree can be generated; thereby, the ground of the maximum error size value (4.9 mm) is available. After inserting and removing the blade for 5,000 times, it can still meet the qualified pressure value of the minimum insertion size of the minimum error size (4.3mm).

In addition, the outer ends of the pair of elastic arm contact pieces are further formed with outward chamfered edges; further, the longitudinal length of the insertion and extraction portions is 1.5 to 4 times the lateral length.

Thereby, the insertion portion is hollowed out in a frame-shaped hollow shape, and the elastic arm contact piece bent more than 90 degrees from the outside to the inside is punched out and the insertion hole is formed, because the elastic arm contact piece has two bends The elastic arm is folded to produce a large elastic force and deformation curvature.

First, referring to [Fig. 2] to [Fig. 4], the present invention relates to a pole piece 20 having at least one insertion and removal portion 20a, and the insertion and extraction portion 20a is a frame-shaped hollow type in which the inner region is hollowed out. The longitudinal length a2 of the insertion and extraction portion 20a is 1.5 to 4 times the lateral length b2, and the insertion and removal portion 20a is punched out to the elastic arm contact piece 21 by one of 90 degrees or more and formed into a socket. 22, the insertion hole 22 can be inserted into the ground insertion blade 30 of the plug, and the outer end of the pair of elastic arm contact pieces 21 is in electrical contact with the ground insertion blade 30, and each of the elastic arm contact pieces 21 is There are two bending elastic arms 212, which can generate a large elastic force and deformation bending, and the outer ends of the pair of elastic arm contact pieces 21 can be further formed with an outward chamfered edge 211.

Based on the configuration, the present invention allows the insertion and removal portion 20a to be hollowed out in a frame-shaped hollow shape, and punches the elastic arm contact piece 21 bent outward by 90 degrees or more and forms the insertion hole 22, and the elastic arm The length of the contact piece 21 may be increased by the longitudinal length a2 of the insertion portion 20a, or the elastic arm contact piece 21 may be bent more than 90 degrees from the outside to the inside (no prior art bending axis must be moved inward relative to the edge) The limitation is that, under the condition that the width w2 after the insertion and removal of the insertion portion 20a is equivalent to the width w1 of the prior art, the elastic arm contact piece 21 can be made to have a sufficient length, and further the elastic arm contact piece is further provided. 21 is a frame-shaped hollow type hollowed out in the inner region, so that the elastic arm contact piece 21 has two bent elastic arms 212, which can generate a large elastic force and deformation bending degree, thereby having a better insertion and extraction pressure. Focusing on, and because of the large angle of elasticity, a large amount of wear material can be generated without reducing the wear force due to the reduction of the wear material for multiple times, and the elastic arm can contact the outer end (electrical contact end) of the sheet 21 Excellent flexibility and ability to withstand higher insertion The number of times and the downward pressure does not change; further, please refer to the chamfered edge 211 of the outer end of the elastic arm contact piece 21 as shown in [Fig. 5] and [Fig. 6], further allowing the ground insertion blade 30 to be further Plug and unplug, and has the function of two-way plugging and unplugging.

In summary, the structure disclosed in the present invention is unprecedented, and can indeed achieve the improvement of efficacy, and has industrial availability, fully conforms to the new patent requirements, and invites the bureau to grant patents to encourage innovation.
