Abstract

PURPOSE:To make a connection part free from easy separation even when tensioned and enable the easy separation and opening of the connection part for inspection, shifting and the like by providing a stopper at the connection part of a connection terminal against tension. CONSTITUTION:A saw-tooth part 10 is formed at a connection terminal 9 enclosed with a saw-tooth part 5 formed on the connection part of a connection terminal 2, thereby forming a stopper via the engagement of both sawtooth parts 3 and 10 against tension. According to this construction, the connection part of the connection terminals 2 and 9 even when subjected to tension, is not easily separated. Also, when necessary, the connection part can be easily separated, thereby enabling the proper and stable discharge of static electricity charged on a worker M.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a connection terminal for an electrostatic damage prevention device for removing electrical charge from a worker who approaches or contacts a semiconductor device.

[Conventional technology]

FIG. 3 is a configuration diagram showing an outline of the connection terminal portion of this type of electrostatic damage prevention device. In this figure, 1 is a conductive connection line whose one end is connected to the worker M, and 2 is a conductive connection line connected to the worker M. 1st
These connecting terminals are shaped like scissors and are biased to mesh by a spring force. A serrated portion 3 is formed on the meshing portion (contact portion), and the second connection terminal 4 is connected by sandwiching the second connection terminal 4 between the serrated portion 3.

Further, the other end of the connecting cotton 1 is connected to one end of the scissor-shaped first connecting terminal 2. Reference numeral 5 denotes a conductive connecting wire whose one end is connected to the second connecting terminal 4 and whose other end is grounded.

FIG. 4 is a configuration diagram of a connection terminal portion for an electrostatic breakdown prevention device showing another conventional example, in which the same reference numerals as in FIG. The first connection terminal has the function of being pinched or expanded in width by the contact part 7 at the other end by a spring, and this contact part 7 is fitted into the fitting contact part 8a of the second connection terminal 8. By making contact and changing its width, that is, after being pinched and fitted, the width is expanded by spring force and brought into contact with the inner wall of the fitting contact portion 8a to maintain the connection function.

Next, the operation will be explained.

In the conventional example shown in FIG. 3, the connecting cotton 1 is in contact with a part of the body of the worker M, and the first
The connecting terminal 2 and the second connecting terminal 4 are in meshing contact with each other. Further, the connecting cotton 5 of the second connecting terminal 4 is grounded. As a result, the static electricity charged on the human body is transferred to the first connecting terminal 2 by the connecting cotton 1. The static electricity is removed through the second connection terminal 4 and the connection line 5.

Similarly, in the conventional example shown in FIG. 4, the portion where the width of the contact portion 7 of the first connection terminal 6 shown in FIG.
By inserting it into the fitting contact portion 8a of the connector, contact is made, and static electricity is eliminated through the connecting cotton 5.

[Problem to be solved by the invention]

Since the connecting terminal portion of the conventional electrostatic breakdown prevention device is configured as described above, the contact portion between the first connecting terminal and the second connecting terminal can easily be connected when a tensile force is applied thereto. There was a problem that the contact part could separate.

This invention was made to solve the above-mentioned problems, and includes a first connection terminal and a second connection terminal connected to the first connection terminal.
A connection for an electrostatic breakdown prevention device that does not easily separate even if a tensile force is applied to the contact part, and that can be easily opened when separated for inspection, movement, etc. The purpose is to obtain a terminal.

[Means to solve the problem]

The connection terminal for the electrostatic damage prevention device according to Party B's invention is
When at least one of the contact portion of the connecting terminal or the contact portion of the second connecting terminal is provided with a stopper against tensile force, and the contact portion provided with the stopper is sandwiched between the other contact portion, It is provided with a stopper that engages with the stopper.

[Effect]

In the invention of B, at least one of the connecting terminals sandwiched between the other connecting terminals is provided with a stopper portion that can withstand the tensile force, so even if a tensile force is inadvertently applied to the contact portion, the first The contact portion of the second connection terminal will not separate.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a configuration diagram of a connecting terminal portion for an electrostatic breakdown prevention device showing an embodiment of the invention of B. In this figure, the third
The same reference numerals as those in the drawings indicate the same constituent parts, and 9 is a second connecting terminal which is sandwiched between the serrated portions 3 formed at the contact portion of the first contact terminal 2, and the first connecting terminal is attached to the contact portion. A serrated portion 1o that engages with the serrated portion 3 of No. 2 is formed.

The interlocking of these serrations 3 and 10 forms a support against tensile forces.

FIG. 2 is a configuration diagram of a connecting terminal portion for an electrostatic breakdown prevention device showing another embodiment of the present invention. A stopper 12 is provided, and when the first connection terminal 2 is inserted between the sawtoothed portions 3, the stopper 12 is pulled from one end of the sawtoothed portions 3.

By providing the stopper 12 against the tensile force in this manner, even if an inadvertent tensile force is applied, the first stopper 12 is provided. Second
The contact portions of the connection terminals 2 and 11 do not easily separate, and the static electricity of the worker M can be removed reliably.

In addition, in the above embodiment, the first connection terminal 2 connected to the worker M is configured to sandwich the second connection terminal 9 or 11 connected to the ground, but the same applies even if the reverse is done. The effect of this can be obtained.

[Effects of the Invention] As explained above, the present invention provides a stopper against tensile force on at least one of the contact portion of the first connection terminal or the contact portion of the second connection terminal, and the stopper against the tensile force is provided on the other contact portion. Since a stopper is provided that engages with the stopper when the contact portion is provided with the stopper, the first
Even if a tensile force is applied to the contact portion between the first connecting terminal and the second connecting terminal, the contact portion will not simply separate, and if separation is necessary, it can be easily removed. Therefore, it is possible to obtain a connection terminal for an electrostatic breakdown prevention device that can reliably and stably remove static electricity charged on a worker.
