Description

Electrostatic protection grounding assembly

Technical Field

The utility model discloses an electrostatic protection grounding assembly, and relates to electrostatic protection equipment, in particular to a grounding assembly of an ESD (electrostatic discharge resistor) anti-static table pad.

Background

The grounding assembly currently used for grounding the anti-static table mat is a snap button type or a screw fixing type. The snap button type of the grapple is that a female button of the snap button is arranged on the table pad, a ground wire with a snap button male button is arranged on the table top, and the female button and the male button are buckled to form a ground guiding structure; the snap-on type of the grapple will form a protrusion on the table top that is aesthetically unpleasing and can be easily knocked off by objects, causing a failure in grounding. The screw fixation type uses screws to connect the table cushion, the table and the grounding assembly together in a penetrating way, the installation is troublesome, and the damage to the table is large. The grounding assembly which is convenient to install on site and has small damage to the workbench is very significant for solving the problem.

SUMMERY OF THE UTILITY MODEL

The utility model provides an electrostatic protection grounding assembly, which enables a grounded table mat to be flat and convenient to clean and has simple installation and connection modes.

In order to solve the technical problems, the utility model adopts the following technical scheme: an electrostatic protection grounding assembly comprises conductive cloth connected with a table top pad and a fixing piece for fixing the conductive cloth on the bottom surface of a table.

The fixing piece comprises a sheet-shaped positioning piece with a screw hole and a long groove-shaped metal piece, wherein one side of the bottom of the metal piece is upwards close to a table, the screw hole is formed in the bottom of the groove and corresponds to the screw hole of the positioning piece, and the end parts of the positioning piece and the metal piece, which clamp conductive cloth, are fixed on the bottom of the table.

Two groove edges of the metal piece extend vertically downwards, the end part of each groove edge is of a turning structure and is turned into a through hole for inserting a plug of a grounding wire, and the groove edge of one metal piece is turned into a through hole, so that four plugs can be inserted in the front and the back.

The groove edge of the metal piece can be used for clamping the crocodile clip joint.

The grooves of the metal piece can be arranged to be parallel to the side edges where the conductive cloth is located according to the habit of an operator.

The groove of the metal piece can also be arranged to be vertical to the side edge of the conductive cloth according to the habit of an operator.

The electrostatic protection grounding assembly is connected with the table mat by using the conductive cloth, so that the table mat is prevented from protruding, and articles on the operation table can be conveniently placed; the fixing piece is used for fixing the conductive cloth, the field installation is convenient, four grounding jacks are arranged on the front and the back of the fixing piece, the multi-point connection is convenient to realize, and the connection of a grounding wire and a wrist strap is very convenient; the operation platform is fixed by screws, is easy to disassemble and assemble and is convenient to change.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, the electrostatic protection grounding assembly of the present invention includes a conductive cloth 1 connected to a table pad of a table top, and a fixing member 2 for fixing the conductive cloth 1 to a bottom surface of the table. Mounting 2 includes the flaky, have the spacer 21 of screw and long flute profile's metalwork 22, the desk is pressed close to the tank bottom one side of metalwork 22 upwards, the tank bottom is equipped with the screw and corresponds with the screw of spacer 21, the vertical downwardly extending in two trough fronts of metalwork 22, the tip on trough fronts is the structure of turn-up, the turn-up becomes the through-hole for peg graft the banana plug of earth connection, be crocodile clamp joint if the earth connection, can press from both sides the centre gripping with the crocodile on the trough fronts of metalwork 22. The groove edge of one metal piece 22 is turned into a through hole, and four plugs can be inserted in the front and the back.

When the desk is installed, one side of the conductive cloth 1 is provided with the non-setting adhesive, the side using the non-setting adhesive is adhered to a desk and is adhered to the bottom surface of the desk downwards along the desktop, the end of the conductive cloth 1 is adhered to the bottom surface of the desk after being adhered to the positioning piece 21, the bottom surface of the groove of the metal piece 22 is aligned to the fixing piece 21, and the metal piece 22, the conductive cloth 1 and the fixing piece 21 are screwed to the bottom surface of the desk through bolts.
