Description

  The present invention relates to a conductive blade holder fixing structure for an outlet in which a conductive blade holder and a conductive piece are closely fitted and fixed to each other so that no deviation occurs.

For example, there are adapter outlets, expansion outlets, table taps, etc., which are used for general electric appliances. However, it is possible to avoid the occurrence of dangerous situations such as overheating and ignition due to current overload on the electric circuit. In order to do this, an overload protection device is usually installed on the electrical circuit of the outlet.
Such an overload protection device can interrupt the electric circuit under the influence of high temperature if the operating temperature of the electric circuit is too high or the current is too large, thereby ensuring the safety of electricity use. Yes.

However, each expansion outlet and each table tap usually have multiple sets of “outlet units”, and one set of “outlet units” is used for one plug, but multiple sets of “outlet units” Since one overload protection device is shared, if the overload protection device cuts off the electric circuit, all the “outlet unit” electric circuits are cut off, which is inconvenient in use.
Also, after all the electrical circuits were cut off at the same time, the user could not know which “outlet unit” had the problem and found out which “outlet unit” caused the interruption of the electrical circuit. However, it is not ideal for use because it is not known whether a failure occurred in the conductive blade holder of the “outlet unit” or whether the failure of the electrical appliance itself caused a short circuit problem.

Therefore, the present applicant has previously proposed an overheat destruction type safety structure and an outlet and a plug provided with the overheat destruction type safety structure described in Patent Document 1.
As shown in FIG. 17, the outlet and the plug are provided with a hot-wire elastic piece B1 provided with a hot-wire terminal B extended, and are opposed in advance between the hot-wire elastic piece B1 and the hot-wire copper piece B2. An open circuit break position is provided. The hot-wire elastic piece B1 and the hot-wire copper piece B2 are brought into contact with each other by the position regulating member D to form a passage position, and the hot-wire elastic piece B1 has a recovery elastic force. Moreover, the neutral wire terminal C is provided with the neutral wire elastic piece C1 provided by extending, and an electric circuit interruption position opened in advance relative to the neutral wire elastic piece C1 and the neutral wire copper piece C2 is provided. Is provided. The neutral wire elastic piece C1 and the neutral wire copper piece C2 are brought into contact with each other by another position regulating member D to form a passage position, and the neutral wire elastic piece C1 has a recovery elastic force. The hot-wire elastic piece B1 and the neutral-wire elastic piece C1 have a recovery elastic force formed by bending the material, and between the hot-wire elastic piece B1 and the hot-wire copper piece B2 using the recovery elastic force. Can be opened when necessary, and the electric circuit can be cut off, or the neutral wire elastic piece C1 and the neutral copper piece C2 can be opened when necessary to cut off the electric circuit.

In addition, the live wire copper piece B2 and the live wire elastic piece B1 are tightly sandwiched by the position restricting member D to form sufficient contact with each other, and at the same time, the neutral wire copper piece C2 and the neutral wire elastic piece C1. Between the two, the other position restricting member D is tightly sandwiched to form a sufficient contact with each other. For this reason, it is comparatively excellent in the conductive effect, and the temperature generated by current conduction at these locations can be effectively reduced.
And, when an overload of current occurs in an arbitrary outlet in the table tap E, or a short circuit of the electric circuit or overheating of the electric circuit occurs, the contact part of the hot wire copper piece B2 and the hot wire elastic piece B1 or the neutral wire copper piece The operating temperature of the contact portion between C2 and the neutral linear elastic piece C1 reaches the heat deformation temperature (for example, 120 ° C.), and the two position restricting members D are deformed and broken under the influence of the heat deformation temperature. At this time, the hot-wire elastic piece B1 is separated from the hot-wire copper piece B2 by the above-described recovery elastic force, or the neutral-wire elastic piece C1 is separated from the neutral-wire copper piece C2 by the above-described recovery elastic force, from the passage position. The current supply is interrupted and the supply of current is interrupted, so that a continuous increase in operating temperature can be avoided.
Since the two position restricting members D are non-conductive materials, even if the position restricting members D are deformed and broken by heat, or further split into two, the position restricting members D after being broken are peripheral electronic elements. Because it will never cause a short circuit by touching, it has high safety.

  The above-mentioned conventional overheat destruction type safety structure can cut off the electric circuit of the conductive blade holder (that is, the live wire terminal B and the neutral wire terminal C) of the individual “outlet unit” insertion port, and the other unit insertion port is normal Does not affect the use of power supply. However, since the two conductive blade holders are used to receive the insertion of the plug blades of the plug, the two conductive blade holders are likely to be displaced when the plug blades are inserted and removed unless a good fixing structure is provided. The wobbling of the contact surface of the conductive blade holder may cause the position restricting member D to loosen.
