Definitions

  • a static dissipative or ESD smock is commonly used in electronic devices manufacturing environment to drain static charges from the operation personnel. It is also important that such ESD smock ideally is groundable so as to enable any static charge that may be floating or residing on the ESD smock generated through the personnel's movement or transferred from the inner clothing by static charge induction be drained away when the ESD smock is grounded.
  • the primary objective of this application is to provide a conductive wrist band comprising a conductive coiled spring wrist band and a snap-on button.
  • the conductive coiled spring wrist band is attached to a sleeve opening rim region of a static dissipative smock via the snap-on button for providing a body-to-smock electrical connection to allow dissipation of static charges from a human body to the static dissipative smock or from the static dissipative smock to the human body whenever a person put on the static dissipative smock.
  • the conductive coiled spring wrist band further comprises a protective stretch-limit elastic fine cord permanently installed inside a hollow centre path of the conductive coiled spring wrist band to achieve a deformation-free conductive coiled spring wrist band.
  • a metallic wire of the conductive coiled spring wrist band has a diameter in a range from 0.2mm to 0.3mm.
  • the present application provides an unusual alternative grounding means at the sleeve opening rim of a static dissipative smock without the need to monitor the useful life of the band for electrical contact integrity due to loosen or weaken grip and poor electrical contact in a simple, quick and easy way to electrically connect the body to the static dissipative smock or from the static dissipative smock to a human body.
  • the present application has successfully solved the technical problem which was desired to be solved for a long time but not successfully solved in present technical field.
  • Fig. 1 is a diagram of the static dissipative smock according to present application
  • the elastic conductive wrist band 4 is extremely reliable in retracting ability to its original physical state even at a much higher stretching ratio.
  • the elastic conductive wrist band 4 is a conductive coiled spring wrist band attached onto the opening rim region of the sleeve to provide a continuous electrical path permanently to allow free flow of static charge from the conductive coiled spring wrist band 4 to the Static dissipative smock and vice versa by a snap-on button.
  • the elastic conductive wrist band 4 also can be attached onto the opening rim region of the sleeve by stitching, sewing, riveting, plug-in or any other fastening means in other embodiments.
  • the diameter of the metallic wire of the conductive coiled spring wrist band 4 is from 0.1mm to 1.0 mm, more specifically from 0.2mm to 0.3mm.
  • the diameter of the conductive coiled spring wrist band 4 is from 1mm to 10mm, more specifically from 4mm to 6mm.
  • the conductive coiled spring wrist band 4 is made of stainless steel, brass, copper, iron, aluminium or any other metal or alloy, but stainless steel material is preferred in ensuring a clean, durable and a permanent conductor to withstand human sweating, machine washing, machine drying and daily wear and tear.
  • an unique protective stretch-limit elastic fine cord (such as protective stretch-limit elastic fine cord 25 in Fig.2) is permanently installed inside the hollow centre path of the conductive coiled spring wrist band 4 as a part of the design to achieve a deformation-free coiled spring wrist band.
  • the present application provides a ground-able static dissipative smock with a conductive coiled spring wrist band that is attached using a snap-on button onto a smock at the sleeve opening rim region in providing a body-to-smock electrical connection to allow the dissipation of static charge from the body to the static dissipative smock or from the smock to the body whenever a person put on the static dissipative smock.

  • the coiled spring wrist band is made of stainless steel, brass, copper, iron, aluminium or any other metal or alloy, but stainless steel material is preferred in ensuring a clean, durable and a permanent conductor to withstand human sweating, machine washing, machine drying and daily wear and tear.
  • metallic coiled wrist band with wire diameter of 0.2mm to 0.3mm and with coiled wrist band diameter of 4mm to 6 mm is so soft in stretchability and so tender in feeling that one does not feel anything even when it is put on. It feels nothing on the wrist. Its unique "no-feel" stretchability, light weight and the airy ventilation design make it extremely comfortable to a production operator who needs to wear it for a continuous long working hours in a production work environment.
  • a coiled spring wrist band is its excellent electrical contact with the skin of our body. Its direct round-the-wrist electrical contact provides a very effective means of electrical connection from body to the smock. Years of Industrial experience tells us that the integrity of the body-to-smock electrical connection is the most critical control factor for a successful grounding of a production operator in a typical electrostatic protected area (EPA).
  • EPA electrostatic protected area
  • the application provides an unusual alternative grounding means at the sleeve opening rim of a smock without the need to monitor the useful life of the band for electrical contact integrity due to loosen or weaken grip and poor electrical contact in a simple, quick and easy way to electrically connect the body to the smock or from the smock to a human body .
  • the smock electrically connects to the chair; to the ESD wheels or ESD castors; to the ESD floor and subsequently to the ground as a body-to-ground system grounding solution.

Abstract

La présente invention concerne un serre-poignet en ressort hélicoïdal (4) placé autour du rebord d'ouverture de la manche d'une blouse, ledit serre-poignet connectant électriquement la blouse (1) au poignet d'un corps humain de manière à éliminer ou à réduire au minimum le risque que le serre-poignet ne se desserre. L'invention concerne également une blouse pouvant être mise à la terre comprenant un serre-poignet métallique en ressort hélicoïdal (4) fixé sur la blouse à l'aide d'un bouton de type pression au niveau de la région (2) du rebord d'ouverture de la manche de manière à établir une connexion électrique allant du corps vers la blouse qui permette la dissipation de la charge statique du corps vers la blouse ou de la blouse vers le corps dès qu'une personne enfile la blouse.
