Description

TECHNICAL FIELD

[0001] The utility model relates to an improvement for the grounding clamp conductive sheet in the power strip. BACKGROUND

[0002] The power strip has a plurality of sockets, and the sockets are provided with positive conductive clamps, negative conductive clamps, grounding clamps and three bus bars that converge them. All the positive conductive clamps converge on the positive bus bar, and the negative conductive clamps and the grounding clamps also converge on the negative bus bar.

[0003] In combination with the accompanying Figure 1 The existing connection mode of the bus bar and the grounding clamp is as follows: connection holes 3 are provided on the bus bar 1 and the grounding clamp 2, and then rivets 4 are used to connect the two together.

[0004] However, as the use time increases and the number of plug-in and plug-out increases, the riveting part may loosen, affecting the stability and reliability of the connection. In addition, the contact area of the riveting part is relatively limited, which may cause an increase in contact resistance, thereby generating more heat when the current passes through, affecting the conductivity. INNOVATION CONTENT

[0005] In order to overcome the deficiencies of the existing grounding clamp assembly connection mode that is prone to loosening and poor performance, the utility model provides a grounding clamp assembly.

[0006] The technical scheme for solving the technical problems of the utility model is: a grounding clamp assembly, comprising a grounding bus bar and a plurality of grounding clamps, the grounding bus bar is provided with a connecting conductive part at one end, the grounding clamp comprises a strip body, the strip body is provided with conductive elastic clamps on both sides, the middle part of the strip body is provided with a protruding part upward, and the grounding bus bar is welded on the protruding part.

[0007] A preferred protruding part is a protruding part formed by stamping.

[0008] In order to have good conductivity, the protruding part has an upper plane.

[0009] A preferred protruding part is a circular truncated cone type.

[0010] In order to facilitate stamping without deformation, a circular base plate is provided at the middle part of the strip body, and the protruding part is located at the middle part of the circular base plate.

[0011] In order to increase the structural strength, the conductive elastic clamp is also provided with a reinforcing rib.

[0012] In order to improve the conductivity and welding performance, the grounding clamp is inclined and welded on the grounding bus bar, and the welding part on the grounding bus bar has an inclined part that follows the strip body.

[0013] The use of this utility model is the same as that of the existing grounding clamp assembly, both of which need to be placed inside the power strip for use, and will not be described in detail here.

[0014] The beneficial effects of this utility model are as follows: 1. After welding, the strength of the welded connection is generally greater than that of riveting, which can withstand greater current and mechanical stress, and performs better in resisting vibration and impact, and is less prone to loosening or poor contact. 2. The welding has a larger contact area and lower contact resistance, which helps to reduce power loss and heat generation. Attached Figure Description
